MECHANISM FOR COILING WIRE RODS.

SPECIFICATION forming part of Letters Patent No. 445,965, dated February 3, 1891.

Application filed June 26, 1886. Serial No. 206,323- (No model.)

To all whom it Ill/(by concern.-

Be it known that I, FRED H. DANIELS, a citizen of the United States, residing at or-cester, in the county of lVorcester and State of Massachusetts, have invented certain new and useful Improvements in Mechanism for Coiling ire Rods, of which the following, together with the accompanying drawings, is a specification sufficiently full, clear, and exact to enable persons skilled in the art to which this invention appertains to make and use the same.

The object of my present invention is to provide an efficient and practical mechanism for reeling or coiling hot wire rods as they come from the rolling-mill, and to afford facilities for directing the rods either onto the reel or so as to run out upon the table or floor; also, to provide a shield, guard, or cover to contain the reel mechanism and prevent accidents from the swinging end of the rod in case the same is notfully reeled into the coil; also, to provide an efficient mechanism for throwing the reels into and out of action by aid of hydraulic or pneumatic pressure, and facilities for discharging the coils of wire rod from the reels, These objects I attain by mechanism the nature, construction, and operation of which is explained in the followin g description, the particular subject-matter claimed being hereinafter definitely specified.

In the drawings, Figure 1 is a plan view of rod-reeling mechanism, illustrating features of my invention. Fig. 2 is a front view of the same. Fig. 3 is avertical section through the reels drawn to a somewhat larger scale.

In referring to parts of the mechanism, A denotes a frame, table, or case having openings in its top within which the reels or rodcoiling receptacles B B are located, and being arranged in a pit, space, or chamber beneath said table and fullyinclosed thereby, the top area only of the reels being exposed and the top line of the reel being level, or nearly so, with the surface of the table. or platform. At the back of the reels a depressed space or trough a is formed along the table, which trough is preferably somewhat inclined clownward toward its exit end a, which opens above a receiving floor or platform, whereon the rods can be distributed when desired.

The rod-receptacles of the reels B are formed as rotatable tubs, or with cylindrical rims 13', extending upward from their bottom plates, and at intervals along the inner surface of said rims B vertical inwardly-projecting flanges or ribs 1) are arranged thereon, the upper part of the ribs extending inward farther than the lower part, as indicated. A series of upright pins or fingers b form the center of the reel, which fingers preferably incline outward at their tops. The rod is coiled in the space between the fingers b and ribs 1;, and the down ward spread of the ribs and fingers permits the coils of rod to drop in the space instead of being held near the top, thus insuring the complete filling of the reel-space before the rod runs over the top.

C indicates a spider or radially-armed lifting-plate arranged within the reeling-receptacle with its arms extending across the space between the fingers b and ribs 1), and upon which the coiled rod R is supported.

The rod-receptacles are mounted on upright hollow shafts D, which are supported to revolve in bearings e e on suit-able frames Or standards E, and said shafts are respectively provided with a disk or friction-clutch wheel D, having upper and lower inclined frictional surfaces d d. The upper bearing e carries a fixed friction-rim H, to matchthe upper surface (Z of the Wheel D, and arranged in the under bearing c is a sleeve G, which supports a gear G, having formed on or connected therewith a friction-rim, which matches the lower surface d of the wheel D. The shafts D are longitudinally movable in their bearings, and beneath their lower ends I arrange lifting and depressing mechanism, whereby the shafts, rod-receptac1es, and disks D can be raised and depressed, so as to bring either the upper or lower friction-surfaces (Z or d into acting contact with its corresponding rim. lVhen depressed, as at the left in Fig. 3, the frictional contact with the gear-G imparts rotary movement to the reel or re ceptacle B, and when elevated, as at the right in Fig. 3, the frictional contact with the stationary rim It stops the rotation and holds the reel or receptacle at a fixed position.

The spider or lifting-plate O is fixed 011 the end of a shaft or spindle C, disposed. within the hollow shaft D in themanner indicated. Beneath the foot of the shafts D and C, I

arrange a compound or telescoping lifting apparatus operated by hydraulic, steam, or pneumatic pressure, and consisting of a cylinder J, containing a piston or hollow plunger K, that extends up to and acts against the foot of the shaft D, and within said plunger is arranged a secondary or smaller piston or plunger I, that extends up to and acts against the shaft 0', the primary or outer plunger serving as a cylinder for the secondary piston, opening at its lower end into the main cylinder,-so-that the pressure exerted therein will act on both. The inner plunger is provided with a r'ecess'or lug, as at i, to engage with the end of a latch or locking lever L, whereby said plunger can be retained at its lower position. Said latch-lever is fulcrumed on the outer plunger, as at Ya, with its lower end Z passing through an opening in the side and its outer arm connected by red 7' with a treadle M, orother suitable operating mechanism, whereby the attendant can release the catch L when desired. The lug is beveled at its lower side, or so formed that in-the downward movement of the plunger I the catch-lever will automatically pass over the lug. A shoulder or stop is provided on the interior of the hollow plunger, as at s, to limit the upward movement of the plunger I and lifting-plate 0. Suitable pipes 11., with valve mechanism N, are provided for supplying the cylinders with water for exerting hydraulic pressure, said valves being fitted with operating-handles m at convenient positions. The mechanism is driven by gears g on shaft G which is provided with suitable driving pulleys or other means for transmitting motion thereto from any suitable motor.

The rods are delivered to the reels through guide-pipes P, located above the trough a, which pipes are jointed and hinged in such manner that their delivery ends can be swung into line either with the coilirig-receptacles or with the trough a, (see Fig. 11,) so as to deliver the rods into said receptacles, or so they will run out upon the floor at the end a of the trough. Handles p or other suitable means are provided for moving the ends of the guide-pipes, as required.

The rod is introduced into the guide-pipes direct from the rolling-mill, (not shown,) a switch S being employed, when desired, to cause alternate rods to pass to the right or left reel.

A cover or inclosing casin g T is arranged to inelose the ends of the guide pipes and space above the reels in the manner illustrated, so that there will be no danger from the swinging of a loose end or loop of rod which from any reason may accidentally get loose, or is not closely coiled into the receptacles. Said cover T is provided with openings or doors 0, through which to take out the coils of rod, and it is suspended from above by means of chains t or other means, so that itcan be raised up at any time to allow access to the mechanism beneath it.

Guides T are provided in connection with the cover to prevent its swinging ou'tof place as it is hoisted up and down by means of the chains 25 or liftingv apparatus. Said guides preferably consist of rods, channel-bars, or angle-bars fixed in upright position in connection with the table A, with lugs on the cover T which engage with the said channel of the bar and retain the cover in proper relation and alignment as it moves up and down to and from the table or its supportingplatform A.

The operation of my invention is as follows: The pressure in the cylinder K being relieved, the plungers descend by weight of the superimposed mechanism, allowing the friction disk or wheel B to rest in contact with the gear G, as indicated at theleft in Fig. 8. The gear being in motion imparts rotary action to the coil-receiver B, and the rod being led to said receiver through the pipe P is coiled in the annular space between the ribs 1) and fingers b the coil resting upon the arms of the spider-plate G. \Vhcn the coil is formed, the attendant opens the valve letting the hydraulic pressure into the cylinder J, which lifts the plunger K, thereby elevating the shaft D and forcing the disk or friction wheel away from the gear G and into contact with the stationary rim H, as indicated at the right of Fig. 3, thus stopping the rotation of the receptacle. The pipe 1 is in the meantime swung back into line with the trough. The attendant then, by placing his foot in the treadle, releases the catch Z from the secondary plunger 1, and the pressure acting on said plunger forces up the spider-frame 0, raising the .coil of wire to a position above the fingers b (see right-hand mechanism in Fig. 3,) so that it can be conveniently removed through the openingO. The pressure is then permitted to escape from the cylinder J, the spider-plate and receptacle descending to their former position. 'The operation is alternately repeated, one receptacle being unloaded while the other is being filled. In case of any accident or derangement of the mechanism during the ceiling of the rod the pipe P can be shifted or swung back over the trough a, so that the balance of the rod instead of being tangled up in the reeling mechanism is directed out upon the receiving-floor, and the wasting of rods is thus avoided.

In lieu of making the cover or hood T for the reels with doors or openings 0 for discharging the rod, the cover may be made in two parts, or as a hood for each of the ceilingreceptaeles inde1i endently, and be arranged to be raised by the chain t or otherwise lifted from the platform to give access to the coilin g-receptacle and permit the convenient discharge of the wire rod. Such single covers I have indicated by dotted linesin Fig. 1. These covers may be provided with a slot or opening in case it is not desired to extend them 'over the trough a, to permit the end of the guide-pipe to swing to and from the reel.

I do not herein claim the combination, with the reel or coiling receptacle, of a movable guard, hood, or cover and means for raising or lowering said hood; nor the combination, with the reel, of a direct conductor or guide and a switclrdelivery guide for delivering the rod into the reel or directing it past the reel according as said guide is adjusted, these and other features of invention forming the subject of my Letters Patent, No. 373,965, of November 29, 1887 nor do I herein broadly claim a revoluble reel having a continuous peripheral rim and provided with an inner row of upright pins concentric with said rim, the latter being provided on its inner side with a series of inwardly-projecting ribs, for this forms in part the subject-matter of my Letters Patent, No. 5,448, of November 19, 1889.
