Definitions

This invention relates to devices for handling ingots in the process of manufacturing steel; and it has for its objectto provide mechanism whereby the ingots may be handled more conveniently and rapidly than heretofore.
My invention has for its object to avoid, as nearly as possible the manual handling of the ingots, and this I accomplish, first, by mounting the molds or flasks upon a specially-constructed car, in which the molds remain while the molten metal is being poured into them, said car being provided with a pivoted frame, in which the said molds are mounted; secondly, in providing a pushing device by means of which the. ingots may be pushed from the molds into the furnace, said pushing device being so constructed and arranged as to be capable of serving two or more furnaces.

the 6 designates a car which is mounted to ride upon the longitudinal track-beams 2.
Said car consists of the platform 7, which is mounted upon the trucks 8 8.
the platform is provid ed with downwardly-extendin g arms 9, supporting a plate 10, that forms a slide fitting between the track-beams 2 2.
the wheels 11 of the car 6 are provided with spur-wheels 12, that engage the longitudinal rack -bars 3, thereby preventing the wheels from dragging 0r sliding upon the track-beams.
the slideplate 10 serves to prevent lateral displacement of the parts in the device when in operation, as will be hereinafter described.
'13 designates a mast which is mounted pivotally upon the platform of the car.
the upper end of said mast is likewise mounted pivotally in a car or carriage 14, which is mounted to ride upon the upper longitudinal trackbeams of the frame.
the car or carriage 14 is provided with wheels or rollers that ride upon the trackbeams, and it has on the under side a slideplate 15, that fits between said track-beams and prevents the car from being laterally displaced.
the car or carriage 6 is provided with a lug 16, having a notch 17, adapted to be en- 7 gaged by a lever or catch 18, which is pivotally attached to the mast, which latter may thus be locked in position for operation.
the car-platform is provided with a notched lug at each end, with either of which the locking-lever may be placed in engagement.
the mast 13 carries the horizontally-arranged pusher-cylinder, both ends of which are connected with the mast near the upper end of the latter by means of inclined guys or braces 19.
the cylinder which is designated by 20, has the longitudinally-movable pistonrodf21, which is provided with a suitably-located piston 22.
the front end of the pistonrod extends through a packing-box 23 at the front end of the cylinder.
Said head which is cylindrical in shape, is provided with a longitudinal perforation 25,
the front end of the pistonrod is aeo provided with a perforation 28 o receive the hook at the end of the drawing- Kongs when the device is to be used for drawing the ingots from the furnace, as will be hereinafter described.
the front end of the pusher cylinder is provided with a forwardly-extending U-shaped bail or bracket 29, having a perforation 30 for the passage of the piston-rod.
the object of this is to support or partially support the weight of the front end of the piston-rod and to relieve the packing-box 23 of such weight, thereby preventing injury to said packingbox and avoiding the leakage which would otherwise in time result from such strain or wear.
brackets 31 having bearings for a pair of longitudinally-sliding rods 32, which rods also extend through transverse openings 33 in the mast or derrick.
the grappling-arms 34 Pivotally connected to the front ends of the sliding rods 32 are the grappling-arms 34, the front ends of which are provided with hooks 35, adapted to engage perforated lugs or staples at the upper ends of the molds, as will be hereinafter described.
a lever 36 Connected pivotally to one side of the cylinder is a lever 36, having a handle 37, by means of which it may be conveniently manipulated.
the ends of said lever are provided with swiveled eyes 38, encircling the grappling-arms 34 and serving when the lever is manipulated to bring the outer or free ends of said grappling-arms together or apart, as may be desired.
a clutch member 43 is arranged revolubly upon the cylinder between the clutch member 40 and the mast.
the clutch member 43 is provided with a handle 44, by means of which it may be manipulated to force the clutch member 40 in a rearward direction.
the piston-rod in the pushercylinder is operated by hydraulic power, the water being supplied under pressure to the ends of the cylinder through pipes which are designated by 45 and 46. Both of these supply-pipes are connected with a valve-casing 47, containing an ordinary four-way valve 48. Suitably connected with said valve-casing are also the supply-pipe 49 and the exhaust or discharge IIO pipe 50, the latter extending through a vertical perforation in the lower end of the mast.
the valve itself forms no part of my present invention, it being simply so constructed that the supply may be connected with either end of the cylinder, while the exhaust is connected with the other end, or that the supply and the exhaust may both be cut off at will.
the supply-pipe 49 extends from the valve-casing up alongside the mast 13 and through an opening 51 in the side of the latter, and thence in an upward direction through the top of the mast and through the car or carriage 14, above which the said supply-pipe 49 is connected with a swivel-jointed pipe 52, composed of any desired number of sections having their meeting ends connected by swivel-joints, so as to admit of said swivel-jointed pipe being extended or contracted, according to the position of the car carrying the pusher-cylinder.
the end of the swivel-jointed pipe 52 is connected with the main supply-pipe 53, which is mounted adjacent to one of the end plates 4 of the frame.
a pair of longitudinal trackrods 54 having their ends attached to the upper ends of the end plates 4 of the frame, serve to support the swivel-jointed supplypipe.
a hydraulic cylinder designates a hydraulic cylinder, which is arranged alongside of one of the trackbeams 2 upon the base-plate, and which is provided with a piston -rod 56, extending through packing-boxes 57 at both ends of the cylinder.
the piston-rod 56 has a centrallylocated piston 58.
Pipes 59 and 60 for supplying water under pressure, are connected with the ends of the cylinder and with the casing 61 of a four-way valve 62,which is also connected with the main supply and discharge pipes 63 and 64 in such a manner that water may be supplied to either end of the cylinder while it is being discharged from the opposite end, or that both the supply and discharge may be simultaneously out oif.
the valve 62 is operated by means of a lever or handle 65.
brackets 66 To the ends of the piston-rod 56 are attached the brackets 66, each of which is provided with bearings for two pulleys 67 and 68.
Guide-pulleys 69 and 70 are suitably arranged near each end of the bed-frame.
the frameplates 4 are provided near their lower ends with perforations 71, adjacent to which guidepulleys 72 are arranged, and similar guidepulleys 73 are arranged near the upper end of each of said bed-plates 4.
each of the guide-pulleys 69 To the bearingframe of each of the guide-pulleys 69 is attached a wire cable 74, which passes over the pulley 67 at the adjacent end of the pistonrod 56, thence under the guide pulley 69, thence over the guide-pulley 72 and through the perforation 71, and to the adjacent end of the car or carriage 6, where it is securely attached in any convenient manner.
a similar wire cable 75 To the bearing-frame of each of the pulleys 7 O is attached a similar wire cable 75, which passes over the guide-pulley 68 at the adjacent end of the piston-rod 56, thence under the guidepulley 70, and over the guide-pulley 13 to the adjacent end of the car or carriage .14, to which it is suitably attached.
This brake mechanism is considered desirable for the purpose of effectually preventing any possibility of the machinery being displaced while in operation, and it will be seen that such brake mechanism, serving to lock the wheels of the car, having spur-wheels intermeshing with the rack-bars upon the longitudinal track-beams,will effectually and positively prevent longitudinal displacemet of the car,while its lateral displacementis quite as efficiently prevented by the arrangement between the longitudinal track-beams of the slide-plate 10, which forms a part of the car structure.
the piston-rod 56 is provided near each end with an upwardly-extending yoke or bail 77, which rides upon guide-rods 78, which are suitably attached at the ends of the cylinder to the frame-plates 4 at the ends of the frame structure.
the parts of my invention thus far de scribed, and which constitute the mechanism for pushing the ingots from the molds into the furnaces and for drawing the ingots from the furnaces may be operated by two attendants, one of whom is stationed at the valve-lever 65, controlling the mechanism for causing the cars to travel in either direction, andthe other of whom is stationed upon the table or platform 39, whereby they may conveniently manipulate the lever-handle 37, whereby the grappling-rods 34 are actuated, the lever-handle 44, by means of which the clutch member 43 is operated, and a leverhandle 79, which is suitably connected by means of links and connecting-rods with the stem of the valve 48, which latter may thus be maniulated so as to cause the piston-rod to be operated in either direction.
the ingot pushing and drawing mechan ism which has been described in the foregoing, is in practice to be arranged longitudinally between two furnaces, which may be of any suitable construction and dimensions. I prefer this arrangement, for the reason that owing to the fact that the mast or derrick carrying the pusher-cylinder is swiveled in the manner described,it maybe employed to serve two furnaces or sets of furnaces as well as one. Consequently a considerable economy in the initial cost of the plant may be eifected by arranging the pushing and drawing mechanism to serve two furnaces, one on each side, as described.
the tracks 80 Arranged or constructed alongside the bedplate 1 and parallel to the track-beams 2 on said bed-plate are the tracks 80, which extend at one end to the frames upon which the ladles are supported while casting ingots and at the other end to the rolling-mills.
Thesaid tracks are arranged intermediately between the base-plate 1 and the furnaces,which latter are designated by 81.
the mold-supporting car is composed of the longitudinal frame pieces orsills 82, supported upon the wheels 83 and supporting the heavy vertical end frames 84.
the latter are provided with bearings 85, of large diameter, for the trunnion-plates 86, between which and the bearings the friction-rollers 87 are interposed for the purpose of enabling the moldcarrying frame to be conveniently manipulated and adjusted to its proper position.
the trunnion-plates and the an ti-friction rollers are retained in the bearings by means of the annular flange-plates 88, which are suitably secured to the outer and inner sides of the trunnion-plates.
the mold-carrying frame is composed of two heavy side pieces or girders 89, which are provided on their inner sides with flanges 90 'to support the molds when the latter are in a horizontal position and on their outer sides with longitudinal strengthening-ribs 91 and 92, formed, respectively, at their upper and lower edges and longitudinally along the center.
the side pieces or girders 89 are cast hollow, in order to admit of their being filled or charged with water for the purpose of preventing the heat from the ingots from warping or otherwise injuring them.
the ends of the girders are 4 provided with flanges 93, adapted to engage supporting-cleats 94 upon the inner sides of the trunnion-plates.
the molds or flasks which are designated by 99, are in the main of ordinary construction, but are provided with laterally-extend ing supporting plates or flanges 100, that extend through the vertical slots or port-holes 101, which are formed in the side pieces or girders 89 directly above the central strengthening-ribs 92 of the latter.
the slots 101 it will be seen, will admit of a limited movement of the molds or flask 99 in the direction of the length of the latter.
Said molds or flasks are provided at their upper edges with perforated lugs or staples 102, adapted to be engaged by the grappling-rods 34 of the pushing mechanism, which has been hereinbefore described.
mold-carrying frame as support ing a series of four molds; but it is obvious that a greater or less number of molds may be used when desired.
the molds are open at their lower ends, and the bottoms for the said molds consist of a series of blocks 103, mounted upon-or formed integrally with a plate 104, which is provided with an annular upwardly-extending flange 105,surrounding the individual mold-bottoms.
Thebottom plate 104 is provided on its upper side near its ends with perforated lugs or staples 106, by means of which said bottom plate may be suspended under the molds in such a manner as to be capable of being disengaged from the latter for the purpose of enabling the ingots to be pushed out after the molds have been adjusted to an approximately-horizontal position.
the trunnion-plates 86 at the ends of the car are provided with radial slots 107, in which are mounted the supporting devices for the bottom plate of the molds.
Each of said supporting devices comprises a shaft 108, extending through the slot 107 and having at its inner end a downwardly-extending arm 109,
each of the shafts 108 is p"ovided with an arm 111.
each of the trunnion-plates 86 Connected pivotally to the outer side of each of the trunnion-plates 86 at a point near the upper end of the slot 107 is an arm or lever 112, having an eccentric-ring 113,through which the outer end of the shaft 108, having the arm 111, extends.
the eccentric-rings 113 are provided near the fulcra of the levers 112 with notches 114. It will be seen that by manipulating the said levers the shafts 108 may be raised or lifted upwardly in the slots 107, thereby lifting the mold-bottom,which has been previously mounted by its lugs or staples 106 upon the hooks 110 up into contact with the lower ends of the molds.
the mold-bottom may be retained in this position by placing the ends of the operating-levers 112 under studs 115, attached to the trunnionplates.
the mechanism for adjusting the mold-bottom is wholly connected with the trunnion-plates. Hence the latter may be turned so as to adjust the molds to any desired position without changing the position of the mold-bottom, which is important, for reasons which will be hereinafter made apparent.
the trunnion-plate S6, at one end of the car, is provided with a bracket 116, to which is attached a segmental gear or rack 117, which is concentric with the upper half of the trunnion-plate.
Brackets 118, secured to the upper end of the end plate 84, are provided with bearings for a shaft 119, provided with a worm 120, engaging the segmental rack 117.
the shaft 1 .9 has a square end 121, upon which a crank 122 may be placed for the purpose of manipulating said shaft.
the trunnionplates and the mold-carrying frame may be swung or tilted in an arc of one hundred and eighty degrees, thus enabling the molds to be tilted to either side into a horizontal position.
the furnaces 81 are arranged, as above described, alongside of the tracks 80 and parallel to and at a suitable distance from the frames of the ingot pushing and drawing mechanism.
peels 1.24 each of which consists of a plate of suitable dimensions having slightly upturned or curved side edges 125 and provided at its front end with a downwardly-extending arm 126.
the front of the furnace is provided with bearings for a longitudinally-sliding dumpbar 127, which is provided in its front edge with a series of notches 128 to register with the charging-doors 123.
One end of the dump bar is connected by means of the pivoted rod 129 with one arm 130 of a bell-crank lever, which is fulcrumed at 131, and the other arm 132 of which serves as a handle by means of which it may be manipulated to impart alongitudinally-sliding movement to'the dumpbar 127.
the peels 124 are first placed in position, it being unnecessary, however, to slide the said peels into the furnace until the arms or handles 126 engage the notches of the dump-bar.
the ingots When the ingots are afterward pushed into the furnace, they will carry the peels with them until the handles 126 of said peels engage the notches 128 in the dump-bar. It will thus be seen that by manipulating the bell-crank lever in such a manner as to slide the dump-bar in either direction the peel will be tilted, thus rolling or tilting the ingots supported thereon to either side of the chargingdoors of the furnace.
the car carrying the ingot-molds filled with the molten metal is transported upon the tracks 80 from the converting-mill and to the furnace.
the car is so arranged as to bring the molds or flasks into alignment with the charging-doors of the furnace, and the cars 6 and 14, carrying the mast 13 and the pusher-cylinder with its attachments, are then manipulated to bring the said pushencylinder into alignment with one of the molds and furnacedoors.
the adjustment of the pushing mechanism may be very quickly and-easily effected by means of the operating mechanism actuated by the hydraulic cylinder 55.
the moldcarrying frame of the car is then tilted by means of the worm and segmental rack to bring the molds into a horizontal position with their upper ends toward the pusher-cylinder. Vhile the mold-carryiu g frameis being tilted to bring the molds in a horizontal position the bottom plate of the molds is suffered to remain in contact with the lower ends of the latter, which are thereby closed, this being obviously necessary for the purpose of preventing the ingots from dropping out of the molds by gravity.
the eccentric-rings 113 are operated by their levers or handles 112, which are released from under the studs 115 to permit the shafts 108,
the piston By reversing the valve 48 the piston is next caused to recede, and by manipulating the valve controlling the supply of water into the cylinder 58, the carriages supporting the pushing mechanism may now be adjusted to place the piston into alignment with the next mold, after which the operation may be repeated.
the mold-carrying frame is restored to its normal position and conveyed back intothe converting-mill to receive a new charge, while the pushing mechanism is held ready to operate upon the next car-load of ingots that may arrive from the converting-mill.
the dump-bar 127 is manipulated to tilt the ingots into the spaces between the chargingdoors of the furnace, and the peels may then be withdrawn, leaving the furnaces in readiness to receive the second charge.
the pushing-cylinder is reversed and made to serve the furnace on the opposite side.
the ingots have remained in the furnaces for a sufficient length of time to raise them to the desired degree of heat, they may be drawn by using drawing-tongs of ordinary construction provided with hooks to engage the perforation 28 in the front end of the piston-rod.
the head 24: of the piston-rod is meanwhile slid in a rearward direction upon the rod, so as toexpose the said perforation 28, this being done by simply releasing the key 27 from engagement with the recess or opening in the piston-rod.
the grappling-tongs the ingots are drawn out upon a suitably-constructed car, which, inasmuch as it forms no part of my present invention, has not been illustrated in the drawings, and upon which they may be conveyed along the tracks 80 to the rolling-mill.
Another important advantage certain to be derived from my invention is the facility with which the ingots may be handled in a highlyheated state, thereby effecting a considerable saving in the fuel necessary to raise them to the necessary degree of heat for rolling.
a device for handlingingots the combination, with a car or carriage mounted to travel on a suitable track alongside of the heating-furnace, of a hydraulic cylinder swiveled or mounted revolubly upon such carriage or car, a piston-rod mounted to reciprocate in said cylinder, and means for connecting the ends of said cylinder with the source of fluid-pressure and the exhaust, substantially as set forth.

DEVICE FOR HANDLING INGOTS.

SPECIFICATION forming part of Letters Patent No. 440,219, dated November 11, 1890.

Application filed May 13,1890. Serial No. 351,609. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS BRADY, a citi zen of the United States, residing at South Chicago, in the county of Cook and State of Illinois, have invented a new and useful Device for Handling In gots, of which the following is a specification.

This invention relates to devices for handling ingots in the process of manufacturing steel; and it has for its objectto provide mechanism whereby the ingots may be handled more conveniently and rapidly than heretofore.

The invention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

Heretofore in the manufacture of steel it has been customary to set the molds in a pit in the converting-mill to receive the molten metal from the ladle. After casting the ingots they have been stripped of the molds and loaded upon a special car to be transferred to the rolling-mill. This has been a laborious process, and it has been attended with the disadvantage that the ingots have been exposed to the air before being charged into the furnaces, thereby frequently causing the surfaces of the ingots to become cracked.

My invention has for its object to avoid, as nearly as possible the manual handling of the ingots, and this I accomplish, first, by mounting the molds or flasks upon a specially-constructed car, in which the molds remain while the molten metal is being poured into them, said car being provided with a pivoted frame, in which the said molds are mounted; secondly, in providing a pushing device by means of which the. ingots may be pushed from the molds into the furnace, said pushing device being so constructed and arranged as to be capable of serving two or more furnaces.

My invention resides more particularly in the detailed construction of the said car and pushing mechanism, in the mechanism for adjusting and operating the latter, and in such other details of construction which will be portion of a steel-manufacturing plant, comprising the furnaces, the ingot-pushing mechanism, and the mold-carrying car, showing the relative arrangement of the several parts. Fig. 2 is a side elevation of the ingot-pushing mechanism, showing the pusher-cylinder arranged in position for operation and looking toward the front end of said cylinder. Fig. 8 is a vertical sectional view taken on the line 3 3 in Fig. 2, and showing the pusher cylinder in side elevation and the car upon which it is mounted in end view. Fig. 4 is a sectional view taken longitudinally through the pusher-cylinder and transversely through the car. Fig. 5 is a sectional view taken longitudinally through the frame of the push mechanism on the line 5 5 in Fig. Fig. 6 is a perspective detail view of the pushercylinder and adjacent parts. Fig. 7 is an end elevation of the frame in which the pusher mechanism is mounted. Fig. 8 is a detail view, 011 an enlarged scale, of the front end of the pusher-cylinder. Fig. 9 is a side elevation of the mold-carrying car with the molds in position upon the same. Fig. 10 is a longitudinal sectional view of the said car.

Like numerals of reference indicate like parts in all the figures.

1 designates the base-plate, which is mounted upon a very substantial foundation of masonry, and which is provided on its upper side with longitudinal track-beams 2 2, which may be cast or formed integrally with the base-plate. Rack-bars 3 are formed upon the outer sides of the said track-beams.

At the ends of the base-plate 1 are mounted the vertical upright plates or standards 4: 4,

the upper ends of which are connected by the longitudinal track-beams 5 5, which, as shown in the drawings, will be 'L-shaped or composed of plates having upwardly-extending flanges at their outer edges.

6 designates a car which is mounted to ride upon the longitudinal track-beams 2. Said car consists of the platform 7, which is mounted upon the trucks 8 8. The platform is provid ed with downwardly-extendin g arms 9, supporting a plate 10, that forms a slide fitting between the track-beams 2 2. The wheels 11 of the car 6 are provided with spur-wheels 12, that engage the longitudinal rack -bars 3, thereby preventing the wheels from dragging 0r sliding upon the track-beams. The slideplate 10 serves to prevent lateral displacement of the parts in the device when in operation, as will be hereinafter described.

'13 designates a mast which is mounted pivotally upon the platform of the car. The upper end of said mast is likewise mounted pivotally in a car or carriage 14, which is mounted to ride upon the upper longitudinal trackbeams of the frame.

The car or carriage 14 is provided with wheels or rollers that ride upon the trackbeams, and it has on the under side a slideplate 15, that fits between said track-beams and prevents the car from being laterally displaced.

The car or carriage 6 is provided with a lug 16, having a notch 17, adapted to be en- 7 gaged by a lever or catch 18, which is pivotally attached to the mast, which latter may thus be locked in position for operation.

The car-platform is provided with a notched lug at each end, with either of which the locking-lever may be placed in engagement.

The mast 13 carries the horizontally-arranged pusher-cylinder, both ends of which are connected with the mast near the upper end of the latter by means of inclined guys or braces 19. The cylinder, which is designated by 20, has the longitudinally-movable pistonrodf21, which is provided with a suitably-located piston 22. The front end of the pistonrod extends through a packing-box 23 at the front end of the cylinder.

24 designates a head which is mounted detachably at the front end of the piston-rod.

Said head, which is cylindrical in shape, is provided with a longitudinal perforation 25,

by means of which it is mounted slidingly upon the piston-rod, and it has atits rear end a staple or perforated lug 26, through which a key or pin 27 passes into a perforation in the piston-rod, upon which the said head may thus be locked. The front end of the pistonrod is aeo provided with a perforation 28 o receive the hook at the end of the drawing- Kongs when the device is to be used for drawing the ingots from the furnace, as will be hereinafter described.

The front end of the pusher cylinder is provided with a forwardly-extending U-shaped bail or bracket 29, having a perforation 30 for the passage of the piston-rod. The object of this is to support or partially support the weight of the front end of the piston-rod and to relieve the packing-box 23 of such weight, thereby preventing injury to said packingbox and avoiding the leakage which would otherwise in time result from such strain or wear.

The upper and lower sides of the cylinder are provided with brackets 31, having bearings for a pair of longitudinally-sliding rods 32, which rods also extend through transverse openings 33 in the mast or derrick.

Pivotally connected to the front ends of the sliding rods 32 are the grappling-arms 34, the front ends of which are provided with hooks 35, adapted to engage perforated lugs or staples at the upper ends of the molds, as will be hereinafter described. Connected pivotally to one side of the cylinder is a lever 36, having a handle 37, by means of which it may be conveniently manipulated. The ends of said lever are provided with swiveled eyes 38, encircling the grappling-arms 34 and serving when the lever is manipulated to bring the outer or free ends of said grappling-arms together or apart, as may be desired.

39 designates a table or platform which is secured near the lower end of the mast or derrick at one side of the pusher-cylinder. This platform is for the accommodation of the operator whose duty it is to attend to the manipulation of the lever-handle 37 and other parts of the pusher-cylinder, which are to be hereinafter described.

40 designates a clutch member which is mounted to slide longitudinally upon the cylinder, and which is provided with perforated lugs or brackets 41 for the passage of the longitudinal rods 32, which are secured in said brackets. Springs 42 are coiled upon the rods 32 between the

brackets

41 and 31 and serve to force the clutch member 40 and the rods 32 normally in a forward direction. A clutch member 43 is arranged revolubly upon the cylinder between the clutch member 40 and the mast. The clutch member 43 is provided with a handle 44, by means of which it may be manipulated to force the clutch member 40 in a rearward direction. This is for the purpose of drawing the molds containing the ingots up against the head at the front end of the piston-rod when the device is to be operated for pushing the ingots out of the molds, as will be hereinafter described, thereby relieving the mast and other parts of the machine of excessive and unequal strain, which might prove injurious.

The piston-rod in the pushercylinder is operated by hydraulic power, the water being supplied under pressure to the ends of the cylinder through pipes which are designated by 45 and 46. Both of these supply-pipes are connected with a valve-casing 47, containing an ordinary four-way valve 48. Suitably connected with said valve-casing are also the supply-pipe 49 and the exhaust or discharge IIO pipe 50, the latter extending through a vertical perforation in the lower end of the mast. The valve itself forms no part of my present invention, it being simply so constructed that the supply may be connected with either end of the cylinder, while the exhaust is connected with the other end, or that the supply and the exhaust may both be cut off at will. The supply-pipe 49 extends from the valve-casing up alongside the mast 13 and through an opening 51 in the side of the latter, and thence in an upward direction through the top of the mast and through the car or carriage 14, above which the said supply-pipe 49 is connected with a swivel-jointed pipe 52, composed of any desired number of sections having their meeting ends connected by swivel-joints, so as to admit of said swivel-jointed pipe being extended or contracted, according to the position of the car carrying the pusher-cylinder. The end of the swivel-jointed pipe 52 is connected with the main supply-pipe 53, which is mounted adjacent to one of the end plates 4 of the frame. A pair of longitudinal trackrods 54, having their ends attached to the upper ends of the end plates 4 of the frame, serve to support the swivel-jointed supplypipe.

The cars carrying the pusher-cylinder and its attachments are operated or carried along their respective tracks by means of mechanism, as follows:

55 designates a hydraulic cylinder, which is arranged alongside of one of the trackbeams 2 upon the base-plate, and which is provided with a piston -rod 56, extending through packing-boxes 57 at both ends of the cylinder. The piston-rod 56 has a centrallylocated piston 58.

Pipes

59 and 60, for supplying water under pressure, are connected with the ends of the cylinder and with the casing 61 of a four-way valve 62,which is also connected with the main supply and

discharge pipes

63 and 64 in such a manner that water may be supplied to either end of the cylinder while it is being discharged from the opposite end, or that both the supply and discharge may be simultaneously out oif. The valve 62 is operated by means of a lever or handle 65. To the ends of the piston-rod 56 are attached the brackets 66, each of which is provided with bearings for two pulleys 67 and 68. Guide-

pulleys

69 and 70 are suitably arranged near each end of the bed-frame. The frameplates 4 are provided near their lower ends with perforations 71, adjacent to which guidepulleys 72 are arranged, and similar guidepulleys 73 are arranged near the upper end of each of said bed-plates 4. To the bearingframe of each of the guide-pulleys 69 is attached a wire cable 74, which passes over the pulley 67 at the adjacent end of the pistonrod 56, thence under the guide pulley 69, thence over the guide-pulley 72 and through the perforation 71, and to the adjacent end of the car or carriage 6, where it is securely attached in any convenient manner. To the bearing-frame of each of the pulleys 7 O is attached a similar wire cable 75, which passes over the guide-pulley 68 at the adjacent end of the piston-rod 56, thence under the guidepulley 70, and over the guide-pulley 13 to the adjacent end of the car or carriage .14, to which it is suitably attached.

It will be seen that by the foregoing arrangement of parts when the piston-rod 56 is caused to move in either direction the cars or

carriages

6 and 14, supporting the mast 13, with the pusher-cylinder and all its attachments, will be moved in the opposite direction. It will also be seen that the upper and lower cars are moved at precisely the same rate of speed, thereby preventing the possibility of any of the parts of the machine getting out of alignment. It may here be stated that the lower car 6 is to be provided with suitable brake mechanism 175, the special construction of which, however, is not considered a part of my present invention. This brake mechanism is considered desirable for the purpose of effectually preventing any possibility of the machinery being displaced while in operation, and it will be seen that such brake mechanism, serving to lock the wheels of the car, having spur-wheels intermeshing with the rack-bars upon the longitudinal track-beams,will effectually and positively prevent longitudinal displacemet of the car,while its lateral displacementis quite as efficiently prevented by the arrangement between the longitudinal track-beams of the slide-plate 10, which forms a part of the car structure.

The piston-rod 56 is provided near each end with an upwardly-extending yoke or bail 77, which rides upon guide-rods 78, which are suitably attached at the ends of the cylinder to the frame-plates 4 at the ends of the frame structure. By this means the weight of the ends of the piston-rod carrying the pulleyframes 66 is taken ofi the packing-boxes at the end of the cylinder, the advantages of which will be readily understood.

The parts of my invention thus far de scribed, and which constitute the mechanism for pushing the ingots from the molds into the furnaces and for drawing the ingots from the furnaces may be operated by two attendants, one of whom is stationed at the valve-lever 65, controlling the mechanism for causing the cars to travel in either direction, andthe other of whom is stationed upon the table or platform 39, whereby they may conveniently manipulate the lever-handle 37, whereby the grappling-rods 34 are actuated, the lever-handle 44, by means of which the clutch member 43 is operated, and a leverhandle 79, which is suitably connected by means of links and connecting-rods with the stem of the valve 48, which latter may thus be maniulated so as to cause the piston-rod to be operated in either direction.

The ingot pushing and drawing mechan ism, which has been described in the foregoing, is in practice to be arranged longitudinally between two furnaces, which may be of any suitable construction and dimensions. I prefer this arrangement, for the reason that owing to the fact that the mast or derrick carrying the pusher-cylinder is swiveled in the manner described,it maybe employed to serve two furnaces or sets of furnaces as well as one. Consequently a considerable economy in the initial cost of the plant may be eifected by arranging the pushing and drawing mechanism to serve two furnaces, one on each side, as described.

I shall now proceed to describe the structure of the car carrying the ingot-molds, in which the ingots are transported from the converting-mill and to the furnaces. I desire in this connection. to call attention to the patentgranted to me in the United States on the 15th day of October, 1889, No. 412,832, for improvements in devices for casting ingots. This device is the one which it is intended to use in, connection with my present invention, and it provides for the casting or pouring of the molten metal from the ladle directly into, the molds, which are described as being supported upon suitable cars. The special structure of'said cars, however, I purposely omitted to show or describe in the Letters Patent above referred, for the reason that the said car-structure is more properly a part of the present invention.

.1 make the foregoing statement merely to show that I have provided means whereby the ingots may be cast in molds supported upon a traveling car structure.

Arranged or constructed alongside the bedplate 1 and parallel to the track-beams 2 on said bed-plate are the tracks 80, which extend at one end to the frames upon which the ladles are supported while casting ingots and at the other end to the rolling-mills. Thesaid tracks are arranged intermediately between the base-plate 1 and the furnaces,which latter are designated by 81.

The mold-supporting car is composed of the longitudinal frame pieces orsills 82, supported upon the wheels 83 and supporting the heavy vertical end frames 84. The latter are provided with bearings 85, of large diameter, for the trunnion-plates 86, between which and the bearings the friction-rollers 87 are interposed for the purpose of enabling the moldcarrying frame to be conveniently manipulated and adjusted to its proper position. The trunnion-plates and the an ti-friction rollers are retained in the bearings by means of the annular flange-plates 88, which are suitably secured to the outer and inner sides of the trunnion-plates.

The mold-carrying frame is composed of two heavy side pieces or girders 89, which are provided on their inner sides with flanges 90 'to support the molds when the latter are in a horizontal position and on their outer sides with longitudinal strengthening-

ribs

91 and 92, formed, respectively, at their upper and lower edges and longitudinally along the center. The side pieces or girders 89 are cast hollow, in order to admit of their being filled or charged with water for the purpose of preventing the heat from the ingots from warping or otherwise injuring them. The ends of the girders are 4 provided with flanges 93, adapted to engage supporting-cleats 94 upon the inner sides of the trunnion-plates. The

side pieces or girders are secured firmly in the said supporting-cleats by means of keys 95, driven into the said cleats alongside of the flanges 93. The inner sides of the side pieces or girders are provided with vertical supporting-cleats 96 to receive flanges 97, formed at the ends of transverse brace-plates 98, by means of which the said side pieces or girders are securely connected. It will be observed that by this construction and arrangement the parts constituting the moldcarrying frame may be very conveniently and securely put together or taken apart for repairs, while at the same time great strength and firmness of the various component parts are attained, which is obviously important,

vowing to the heavy weight which has to be sustained and the circumstances under which the ingots are to be handled.

The molds or flasks, which are designated by 99, are in the main of ordinary construction, but are provided with laterally-extend ing supporting plates or flanges 100, that extend through the vertical slots or port-holes 101, which are formed in the side pieces or girders 89 directly above the central strengthening-ribs 92 of the latter. The slots 101, it will be seen, will admit of a limited movement of the molds or flask 99 in the direction of the length of the latter. Said molds or flasks are provided at their upper edges with perforated lugs or staples 102, adapted to be engaged by the grappling-rods 34 of the pushing mechanism, which has been hereinbefore described.

In the drawings hereto annexed I have shown the mold-carrying frame as support ing a series of four molds; but it is obvious that a greater or less number of molds may be used when desired. The molds are open at their lower ends, and the bottoms for the said molds consist of a series of blocks 103, mounted upon-or formed integrally with a plate 104, which is provided with an annular upwardly-extending flange 105,surrounding the individual mold-bottoms. Thebottom plate 104 is provided on its upper side near its ends with perforated lugs or staples 106, by means of which said bottom plate may be suspended under the molds in such a manner as to be capable of being disengaged from the latter for the purpose of enabling the ingots to be pushed out after the molds have been adjusted to an approximately-horizontal position.

The trunnion-plates 86 at the ends of the car are provided with radial slots 107, in which are mounted the supporting devices for the bottom plate of the molds. Each of said supporting devices comprises a shaft 108, extending through the slot 107 and having at its inner end a downwardly-extending arm 109,

provided at its lower end with a hook 110.

The outer end of each of the shafts 108 is p"ovided with an arm 111.

Connected pivotally to the outer side of each of the trunnion-plates 86 at a point near the upper end of the slot 107 is an arm or lever 112, having an eccentric-ring 113,through which the outer end of the shaft 108, having the arm 111, extends. The eccentric-rings 113 are provided near the fulcra of the levers 112 with notches 114. It will be seen that by manipulating the said levers the shafts 108 may be raised or lifted upwardly in the slots 107, thereby lifting the mold-bottom,which has been previously mounted by its lugs or staples 106 upon the hooks 110 up into contact with the lower ends of the molds. The mold-bottom may be retained in this position by placing the ends of the operating-levers 112 under studs 115, attached to the trunnionplates.

It will be seen that the mechanism for adjusting the mold-bottom is wholly connected with the trunnion-plates. Hence the latter may be turned so as to adjust the molds to any desired position without changing the position of the mold-bottom, which is important, for reasons which will be hereinafter made apparent.

The trunnion-plate S6, at one end of the car, is provided with a bracket 116, to which is attached a segmental gear or rack 117, which is concentric with the upper half of the trunnion-plate. Brackets 118, secured to the upper end of the end plate 84, are provided with bearings for a shaft 119, provided with a worm 120, engaging the segmental rack 117. The shaft 1 .9 has a square end 121, upon which a crank 122 may be placed for the purpose of manipulating said shaft. It will be seen that by this mechanism the trunnionplates and the mold-carrying frame may be swung or tilted in an arc of one hundred and eighty degrees, thus enabling the molds to be tilted to either side into a horizontal position.

It is obvious that the parts of the mold-carrying car and the pushing mechanism are to be so proportioned with relation to each other that the molds when occupying a horizontal position shall be practically in horizontal alignment with the piston-rod of the pushercylinder.

The furnaces 81 are arranged, as above described, alongside of the tracks 80 and parallel to and at a suitable distance from the frames of the ingot pushing and drawing mechanism. The said furnaces'are in the main of ordinary constructiona suitable number of charging-doors 123, which are located a suitable distance apart, so as to enable two ingots to be charged through each one of the doors, means being provided, as will be presently described, for tilting the ingot, which is first charged to either side of the charging-door, so as to leave room for the next one. For the purpose of thus tilting the ingots out of alignment- With the chargingdoors, I avail myself of the peels 1.24:, each of which consists of a plate of suitable dimensions having slightly upturned or curved side edges 125 and provided at its front end with a downwardly-extending arm 126.

The front of the furnace is provided with bearings for a longitudinally-sliding dumpbar 127, which is provided in its front edge with a series of notches 128 to register with the charging-doors 123. One end of the dump bar is connected by means of the pivoted rod 129 with one arm 130 of a bell-crank lever, which is fulcrumed at 131, and the other arm 132 of which serves as a handle by means of which it may be manipulated to impart alongitudinally-sliding movement to'the dumpbar 127. When the ingots are pushed or charged into the furnace, as will be hereinafter described, the peels 124 are first placed in position, it being unnecessary, however, to slide the said peels into the furnace until the arms or handles 126 engage the notches of the dump-bar. When the ingots are afterward pushed into the furnace, they will carry the peels with them until the handles 126 of said peels engage the notches 128 in the dump-bar. It will thus be seen that by manipulating the bell-crank lever in such a manner as to slide the dump-bar in either direction the peel will be tilted, thus rolling or tilting the ingots supported thereon to either side of the chargingdoors of the furnace.

In the practical operation of my invention the car carrying the ingot-molds filled with the molten metal is transported upon the tracks 80 from the converting-mill and to the furnace. The car is so arranged as to bring the molds or flasks into alignment with the charging-doors of the furnace, and the

cars

6 and 14, carrying the mast 13 and the pusher-cylinder with its attachments, are then manipulated to bring the said pushencylinder into alignment with one of the molds and furnacedoors. The adjustment of the pushing mechanism may be very quickly and-easily effected by means of the operating mechanism actuated by the hydraulic cylinder 55. The moldcarrying frame of the car is then tilted by means of the worm and segmental rack to bring the molds into a horizontal position with their upper ends toward the pusher-cylinder. Vhile the mold-carryiu g frameis being tilted to bring the molds in a horizontal position the bottom plate of the molds is suffered to remain in contact with the lower ends of the latter, which are thereby closed, this being obviously necessary for the purpose of preventing the ingots from dropping out of the molds by gravity. When the mold-carrying frame hasbeen sufficiently tilted to bring the molds into a horizontal position, or nearly so, the eccentric-rings 113 are operated by their levers or handles 112, which are released from under the studs 115 to permit the shafts 108,

having the supporting-hooks 110, to move outwardly in the slots 107, thereby releasing the bottom plate from the lower ends of the molds and permitting the said bottom plate to swing down between the ends of the car-frame. The lever-man or operator, who

is stationed upon the platform 39, now manipulates the pivoted grappling-arms 34 by means of the lever 36 and handle 37 to cause the hooks 35 at the front or outer ends of said grappling-arms to engage the lugs or staples 102 at the upper ends of the holes or flasks 99. This having been done, he next operates the clutch member 43 by means of the lever or handle 44: to force the clutch membereO and the rods 33, to the front ends of which the grappling-rods are journaled, in a rearward direction against the tension of the springs 42, thus drawing the mold containing the ingot up into contact with the head 24 at the front end of the piston-rod 20 in the pusher-cylinder and serving to hold the said mold securely While the ingot is being pushed out. The sliding movement of the mold just described is made possible by the presence of the vertical slots or port-holes 101 in the moldcarrying frame in which the said molds are supported by their flanges 100. The leverman now manipulates the operating rod or handle 79 of the valve 48 to so adjust said valve as to cause water under pressure to be admitted through the pipe 46 into the rear end ofrthe cylinder, thus causing the pistonrod to move in a forward direction and to push the ingot out of the mold and into the furnace through the charging-door with which it is in alignment. By reversing the valve 48 the piston is next caused to recede, and by manipulating the valve controlling the supply of water into the cylinder 58, the carriages supporting the pushing mechanism may now be adjusted to place the piston into alignment with the next mold, after which the operation may be repeated. When all the ingots have been pushed into the furnace, the mold-carrying frame is restored to its normal position and conveyed back intothe converting-mill to receive a new charge, while the pushing mechanism is held ready to operate upon the next car-load of ingots that may arrive from the converting-mill. After all the furnacedoors have received their first charges the dump-bar 127 is manipulated to tilt the ingots into the spaces between the chargingdoors of the furnace, and the peels may then be withdrawn, leaving the furnaces in readiness to receive the second charge. After having served the furnace on one side of the pushing mechanism the pushing-cylinder is reversed and made to serve the furnace on the opposite side. When the ingots have remained in the furnaces for a sufficient length of time to raise them to the desired degree of heat, they may be drawn by using drawing-tongs of ordinary construction provided with hooks to engage the perforation 28 in the front end of the piston-rod.

The head 24: of the piston-rod is meanwhile slid in a rearward direction upon the rod, so as toexpose the said perforation 28, this being done by simply releasing the key 27 from engagement with the recess or opening in the piston-rod. By the use of the grappling-tongs the ingots are drawn out upon a suitably-constructed car, which, inasmuch as it forms no part of my present invention, has not been illustrated in the drawings, and upon which they may be conveyed along the tracks 80 to the rolling-mill.

The advantages of my invention will be readily understood from the foregoing description,taken in connection with the drawings hereto annexed, by those skilled in the art to which it appertains. By the ordinary method of manipulating ingots it has been customary to strip the ingots from the molds in the converting-mill, where the molds are set for casting in a pit under the pouringladle. The process of stripping the ingots has necessarily been slow and laborious, requiring the assistance of numerous operators, the services of many of whom may be dispensed with by my invention. In addition to this the steel, is kept in a far better condition than heretofore, owing to the fact that it is at no time between the casting of the ingots and the charging of the ingots into the furnace exposed to the drafts of cold air, which have heretofore been instrumental in cracking and injuring the surfaces of the ingots, frequently entailing considerable loss, owing to the inferior quality of the product.

Another important advantage certain to be derived from my invention is the facility with which the ingots may be handled in a highlyheated state, thereby effecting a considerable saving in the fuel necessary to raise them to the necessary degree of heat for rolling.

Other advantages might be mentioned;but it is thought that the foregoing will be suificient to illustrate the superiority of my improved devices for handling ingots over the methods ordinarily employed.

In the detailed construction of the various parts of my invention I have aimed not only at so constructing the various parts of the mechanism as to facilitate the actual handling of the ingots, but I have had specially in mind the difficulties to be overcome owing to the heavy weights to be handled and the highly-heated condition of the ingots.

It is obvious that all of the structural parts attained these objects by the construction" and arrangement of parts herein described, and illustrated in the drawings hereto annexed; but I desire to have it distinctly un derstood that I reserve the right to any changes and modifications which may be resorted to without departing from the spirit of my invention.

I also desire it to be understood that While for various reasons I consider hydraulic pressure to be preferable as a motive and actuating power in connection with my invention I reserve the right to use any other fluidpressure.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
