MACHINE FOR TREATING METALLIC TIRES.

Application filed. February 2, 1907.

. To all whom it may concern:

Be it known that I, EDWARD L. T. SCHAUB, citizen of the United States, residing at O- lumbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Machines for Treating Metallic Tires, of which the following is a specification.

My invention relates to new and useful improvements in tire treating machines.

The object of the invention is to provide a machine constructed to permit adjustments in various directions, also adjustments of an extremely fine character.

A further object resides in the provision of means for optionally cutting or milling the face and flange of the tire together with improved means for bodily raising and lowering arlid swinging the machine in a horizontal ane.

Finally the object of the invention is to provide a device of the character described that will be strong, durable and efficient, simple and easy of operation, comparatively inexpensive to produce and one in which the several parts will not be liable to get out of working order.

With the above and other objects in view, the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view, Fig. 2 is a longitudinal sectional view taken on the line x-x of Fig. 1 and showing parts of the table and cutter head mechanism in elevation, Fig. 3 is an end elevation showing a part of the gearing in dotted lines, Fig. 4 is a view of the opposite end, Fig. 5 is a partial vertical sectional view of a wheel fitted with a blind tire, and Fig. 6 is a similar view of a wheel fitted with a flanged tire.

In the drawings the numeral 1, designates a horizontal hollow table having a longitudinal flat dovetail guide 2, the latter having a central longitudinal slot 3. This table carries the machine as hereinafter described.

A hollow post t extends from the under central portion of the table, telescoping into a cylindrical bearing box 5, the latter being supported at its upper end by an annular flange 6 resting on a cylindrical pedestal 7 having a horizontal base plate 8. A dovetailed longitudinal groove 9 is formed in the underside of this plate, receiving the dove- Specification of Letters Patent.

tailed portion 10 of a track plate 11, thus permitting the pedestal to be moved longitudinally on the plate 11. For so moving the pedestal, a pinion 12, keyed on a shaft 14.- supported in a bearing secured to one side of the base plate 8, meshes with a rack 16 fas tened to the side of the track 11. It might be here stated that the track is mounted on the bottom of a suitable pit and extends longitudinally thereof. Thus by suitably turning the shaft 14 the pedestal and machine which it supports may be moved longitudinally of the pit.

In the center of the bottom of the bearing box 5 a screw threaded boss 17 receives a vertical adjusting screw 18. This screw is formed nearer its upper end with a collar 19 on which the table 1 rests as is clearly shown in Fig. 2, the said screw passing through the post 4 and into the table.

A worm gear 20 secured on the upper end of the screw is engaged by a worm 21 carried on a shaft 22 extending transversely through the table and having one end projecting a short distance to permit the shaft to be turned by suitable means. It is obvious that motion imparted to the worm gearing will cause the screw 18 to move up or down through the boss, the table being thus either raised or lowered. VJ hen it is desired to swing the table in a horizontal plane set screws 23 carried by the pedestal and impinging the bearing box are loosened and the box turned axially in the pedestal by means of a handle 24 carried by the flange 6. After the parts have been swung they may be locked in place by tightening the set screws.

The table 1 supports a carriage 25 having a central longitudinal dovetail groove rece1ving the fiat guide 2, the table being somewhat longer than the carriage to permit a longitudinal adjustment of the latter. This adjustment is accomplished by a screw 26 having one end supported by the table and the other passing through a lug 27 project ing into the slot 3 from the carriage. The screw projects from the end of the table so as to be turned by a suitable tool to move the carriage. It will be observed that as shown in the drawings the table and the carriage occupy a position at right angles to the track plate 11, thus lying transversely of the pit. Of course by means of the handle 24 the table and carriage may be swung to different angles in a horizontal plane with relation to the track. Further the adjustments of the different parts are absolutely independent, each operating to bring the machine into or out of contact with the work.

At the forward end and sides of the carriage outwardlyextending bearings 28 are provided. A machine frame 29 fits snugly at its forward end between the bearings, being provided with inwardly projecting bearing rings 30 embracing a hinge shaft 31 supported in bearings 28. This frame has a box like shape having a top plate 32 and an open rear end. Central ears 33 projecting from the under side of the top pivotally receive the upper end of a turn buckle 34 pivotally supported at'its lower end between ears 35 projecting upward from the rear end of the carriage. The entire frame is thus supported on the hinge shaft 31 and the turn-buckle 34 so that by adjusting the turn buckle the frame may be swung in an are having its center in the said shaft. At its forward end the frame top 32 is formed with an upwardly projecting boss 36 which supports a flanged sleeve 37 projecting down into the frame and passing through an inverted flanged collar 38 secured to the underside of the top. A flanged cutter head 39 rests on ball bearings arranged on the flanged portion of the sleeve 37 and is fixedly secured on the upper end of a head shaft 40 passing loosely down through the said sleeve and projecting some distance below the same. The lower end of the sleeve is externally screw threaded and receives a cupped nut 41 internally screw threaded and engaging the collar 38 which is also screw threaded. By adjusting this nut, the sleeve 37 and the cutter head are raised or lowered. The threads on the sleeve are of a smaller pitch than those on the collar which affords means for adjusting the head vertically to a minute degree. It is to be understood that suitable means for preventing the sleeve 37 from turning in the boss 36 is provided.

The cutter head 39 may be of any approved design arranged to rotate and carrying a plurality of cutting tools 42 adj ustably mounted in a circle and near the edges there of. It is to be noted that several conditions are encountered in treating or truing tires, especially tires of locomotive wheels. In Figs. 5 and 6 I have shown the usual flanged tire and what is known as a blind tire.

The flanged tire generally has a beveled face,

plished by the cupped nut 41, while by means of the turn buckle 34 the machine frame and cutter may be swung to the proper angles to cut the 'bevels. The reason for these various adjustments is apparent when one considers that the work done is calculated in fractions of an inch and further the wheels carrying the tires are often mounted offcenter making a perfect adjustment necessary for a true cut.

To one side of the cutter head and the machine frame a horizontal leaf 43 having a lon gitudinal dovetail guide 44 is provided. This guide enters a similar shaped guide-way in the base of an adjustable standard 45 having a bearing 46 carrying a mandrel 47 pro jecting from each end thereof.

The extension or leaf 43 is formed on the machine side with a longitudinal lug 48 which fits between ears 49 projecting from the machine frame 29. A shaft 50 passes through the ears and the lug, a hinged joint thus being formed which permits the leaf 43 and standard 45 to be swung. The reason for swingingly mounting these parts is to ob tain an adjustment of a grooved cutting wheel 51 carried on the forward end of the mandrel 47. This wheel is employed to cut the flange of the tire being treated and as these latter tires vary in diameter, a swinging adjustment is necessary. Further where tires without flanges are treated it may be necessary to swing the cutting wheel out of the way. For obtaining this adjustment a web 52 is extended at right angles from the side of the frame 29 as shown in Figs. 3 and 4 and in dotted lines in Fig. 1. This web at its lower end is provided with bearing hangers 53 disposed at an angle and supporting between them a worm screw 54, the outer end of the latter being shaped for a suitable operating tool. The screw 54 meshes with a segmental worm 55formed on the lower end of a vertical plate 56 extending down from the bottom of the leaf 43.

It is obvious that by turning the screw 54 the leaf is swung in or out, the standard 45 and cutting wheel 51 being swung up or down. This swinging means takes care of the adjustment of the cutting wheel in a vertical plane; but for adjusting the cutting wheel in a horizontal plane orlaterally of the flanged wheel, the standard is moved back and forth on the guide 44. This is accomplished by a screw 57 extending along the outer side of the leaf 43 and shaped at its rear end for a suitable operating tool. The screw is rotatably mounted at its rear end, but held against longitudinal movement in a boss 58 project ing from the leaf, while the forward portion of the screw engages in an arm 59 projecting down from the standard 45, as shown in Figs. 1, 3 and 4. By turning this screw the stand ard may be adjusted back and forth on the guide 44. Should it be necessary to square the cutting wheel with the flange of the wheel being treated, the machine can be turned on its vertical axis by means of the handle 24 as before described.

I will now describe the gearing for operating the cutter head 39 and the cutting wheel 51. A driving gear 60 is mounted parallel to the side of the machine frame 29 in a bearing 61 cast on the upper right hand side of the frame with relation to Fig. 3. This gear meshes with an under gear 62 mounted on the projecting end of a shaft 63 extending transversely through the frame and supported in bearings 64 projecting from the oppo site side of the said frame. A beveled pinion 65 is keyed on the shaft 63 within the frame and meshes with a vertical bevel gear 66 keyed on the end of a shaft 67 extending longitudinally through. the frame. This shaft is supported in bearings 63 cast on transverse partition. walls or plates 69 forming a part of the machine frame 29 as is shown in Fig. 2. On the end of the said shaft and outside of the forward partition wall, a bevel pinion 70 is keyed. This pinion meshes with a horizontal bevel gear 71 arranged below the center thereof and receiving the head shaft 40. This gear is supported on a bearing frame 72 projecting forward from the forward parti tion wall 69. It will be apparent that this gear is driven by the pinion 70 and in order to permit a vertical adjustment of the shaft 40 and cutter head 39 as hereinbefore described, suitable means, as a key 73, is interposed between the shaft and the gear, the shaft thus loosely passing through the gear and being driven thereby.

Motion may be imparted to the driving gear 60 in any suitable manner or if desired a motor as shown in dotted lines in Fig. 2 may be mounted on the top 32 of the ma chine frame and connected with the said gear. This gear drives the gear 62 which being fixed on the shaft 63 conveys motion to the bevel gear 66 by means of the bevel pinion 65. This gear being fixed on the end of the shaft 67 rotates the same and trans mits motion to the head shaft 40 and cutter head 39 by means of the bevel pinion 70 and gear 71. On the shaft 67 between the partition walls a spur pinion 74 is mounted and held in place by a set screw 75. This pinion meshes at one side with a pinion 76 mounted on the wall 69 as shown in dotted lines in Fig. 3. Above this last named pinion a third pinion 77 is mounted in a bearing 78 projecting from the partition wall, motion thus being imparted from the pinion 74 to the pinion 77 j by the pinion 76.

The top 32 and side of the machine frame are cut away to receive a broad face pinion 79 loosely mounted on the shaft 50 hereinbefore referred to. This pinion is held in place between one of the ears 49 and a lug 80 projecting from the side of the machine frame as shown in Fig. 1. On the rear end of the mandrel 47 which carries the cutting wheel 51, a spur gear 81 is mounted, having engagement with the broad face pinion from which it receives motion, the latter being driven by the pinion 77. By provision of the broad face pinion the standard 45 may be adjusted longitudinally of the machine with out throwing the gear out of contact with the pinion. It is also to be noted that by mounting the leaf 43 and. the pinion 79 on the same shaft the engagement between the said pinion and the gear 81 will not be broken when the leaf is swung by the worm gear. Should it not be necessary or desirable to use the cutting wheel the set screw 75 may be loosened and the pinion 74 moved forward out of mesh with the pinion 76, the transmission of motion thus being interrupted.

ft is to be understood that the machine or a plurality of the same is mounted in a suitable pit outside of the track. That portion of the rail 82 nearest the machine is divided into sections capable of movement transversely to the longitudinal center of the track. in each section the rail 82 is mounted on the upper end of a plate standard 33 mounted on a dovetailed track 84 similar to he track 11. Any suitable means for moving this standard and fastening it in place may be employed. I prefer to arrange a section opposite each machine, however the length of the section may vary and extend in front of two or more machines.

Vi hen tires of the wheels of a locomotive are to be treated, the sections are adjusted so that the rail 82 is alined with the track and the locomotive run onto said rail. After the locomotive has been jacked up so as to raise its wheels off the rail 82, the standard 33 is moved inward on the track 34 away from the treating machine. The machine may now be adjusted to bring its metal removing parts into contact with the tire. In

may be necessary. For instance after raising and swinging the machine bodily a fine adjustment of the cutter head 39 is essential, which is obtained by the means of the cupped nut 41, while to secure the proper angle for the bevel, the machine is swung on the hinge shaft 31 by the turn-buckle 34. The cutting wheel 51 may be independently adjusted by the worm screw 54 and the screw 57 and thus brought into proper position.

order to accomplishthis several adjustments 120 It Will be apparent that the position of the 1 machine with relation to the work is at all times under the control of the operator and he is able to adjust any of the parts to a fraction of an inch.

As herein before stated the actual metal removing parts or tools form no particular part of this invention, as the metal may be removed by cutting, milling or grinding the flange and face of the tire, although grinding is hardly desirable in most cases.

I wish to call the attention to the fact that the cutting wheel 51 may be removed and cutting wheels of different shapes substituted. From this it will be apparent that the wheel mounted on the mandrel 47 need not necessarily be used as a flange treating tool as the machine may be suitably adjusted on the track 11 and the said cutting Wheel brought into proper working relation with the tire so that the tread or any part thereof may be treated. When this manner of operation is adopted the cutter head 39 is not used, al though cutting wheels of different shapes may be used in combination with the cutter head.

A very important feature resides in the provision of separate tools for treating the tread and flan e, arranged to be simultaneously or independently operated. It is not believed that anyone has heretofore attempted to treat the tread and flange at the same time with independent tools. It is obvious that by this arrangement much time is saved and by making the tools and their supports independently adjustable little difficulty is experienced in bringing them into proper Working relation with the tire.
