DEVICE FOR HANDLING CAR WHEELS.-

Application filed May 27,

This invention relates to a device for handling car wheels and particularly for handling the wheels used in connection with railroad equipment.

. An object of this invention resides in providing a mechanism for handling carwheels used in railway rolling stock in order to remove or position the wheels in their proper relation under the rolling stock when the same is jacked up and. for placing these wheels from positions adjacent the tracks onto the tracks so they ,may he placed in proper supporting relation under the piece of rolling stock to which the wheels are being applied.

A further object of the invention is to provide a device of the above mentioned character which will facilitate the handling of the wheel so that one or two men may handle a pair of wheels with the useof the present invention to substantially save the time and labor as compared with the old method of handling the wheels with six to eight men.

The invention comprehends numerous other objects residing in the construction of the device which are particularly set forth in the following description and claims directed to a preferred form of the invention, it being understood, however, that various changes in. the size, shape and relation of parts may be made without departing from the spirit and scope of the invention. as herein set forth. 7. I

In the drawings forming part of this application T Figure 1 is a perspective view showing the manner of using the invention in handling car wheels. I s

Fig. 2 is a side elevation of the device with-portions of the base structure broken away'as shown in. section.

F is. 3 is a horizontal sectional view taken on the line 8-3 of Fig, 2. portions below this sectionbroken away to clearly illustrate the parts thereunder.

This invention is provided for use in repairing and replacing parts of railway rolling stock and particularly trucks and wheels, and is designed for use in connection with the repairing of trucks and the removal and replacement of wheels on the rolling stock in places where the usual tools as found in the repair shop particularly maintained for such work are not ordiwhich 1927. Serial No. 194,768.

narily available, to make repairs for the furtheruse ofthe rolling stock.

It is the present practice under such conditions toemploy a large number'of men to.

Referring particularly to Figs. 2 and 3,1

indicates a suitable form of jack of any construction well known in the art which is provided with a lift 2 formed for sliding operation through the body of the jack 1 through the operation of the handle 'Ssuitably pivoted in the jack and operating any desired mechanism for raising and lowering the lift in the jack body. Any of the several forms of jacks designed forthe purpose may be well used in connection with this invention, and for which purpose the hodg' oi the jack is provided with a special base l of annular form as shown in Fig. 3 is formed on the upper edge with an annular recess 5 and at predetermined points adjacent the recess 5 with notches 6. The lower face of the base portion 4 is :lormed adjacent the periphery on the under face with an annular arcuate bearing groove 7 and in the central portion with a depending boss 8 also of annular form.

The central portion of the base 4 is formed with an opening 9 containing the guideway for the shank of the lift 2 so that it. may move to its lowest position in the body of the jack 1. The boss 8 has bearing engagement in the annular upstanding flange 10 which projects upwardly from the space of thesupporting plate 11, and immediately outwardly of this annular flange 10, the plate is formed an annular groove 12 opposed to the groove 7 in the base 4: and between which are positioned the balls 13 to provide an anti-friction bearing support for the jack in the supporting plate 11. The balls 13 provide an effective annular bearing around the periphery of the base 4 for rotatably supporting the jack 1 on the supporting plate 11 while the boss 8 provides an effective means of centering the base in the sup but where it is necessary} occasioned in the manual porting plate and distributing lateral stress applied to the jack directly to the supporting base.

The edge portion of the supporting plate 11 is provided with an annular upstanding wall 14 which receivesaiid hoiisesthe base l therein providing a bearing surface for the peripheral portion of the base. The uper edge of the wall 1 1 terminates in the plane of the bottom portion of the recess 5 andreceives the annular retaining ring 15 which is suitably secured thereto by the bolts 16 or other securing means with the inner-edge seated in the annular recess 5 of the base for efiectively retaining the same in assembled relation with the supporting plate 11. i

At 17, the retaining ring 15 is provided with a pair of ears between which extends the latch member 18; and in which said latch member is pivotally supported thru the use of the pivot bolt 19 while the inner endis formed with a lateral depending extension 20 adapted to seat in-th'e recesses 6 in theba'se portion for' retaining the jack against rotation 111 the plate 11. The opposite end' of this latch member 18 is formed to provide apedal 21 venient release or the base or rotation through depressing-- the pedal portion 21 with the foot. A coiled spring 22 normally retains the latch member 18 in position so that the ends 21 will engage within one of the'recesses'ti. l

his construction provides an assembly in which the parts are in rigidly assembled relation so that all transverse stresses are equally distributed to the supporting plate 11 and at the same time permits the ready rotation of the jack on this supporting plate. This therefore, provides a construction in which the supporting plate may be made with a substantially larger area adapted to seat on a tie or the like, as illustrated in Fig. 1, in order that the hit 2 of the jackmay be brought under a central portion of theaxle 23 of a car wheel for suitably raising the car wheel above the plane of the track to permit rotation mtothe dottedline position of 1, when it is desired to remove awheelfrom the track.

The operation is reversed when it is desired to place a pair of wheels on the track by placing the jack underthe center; of the wheel structure and elevating the same to to permit the conthe dotted line position of Fig. 1, and subsequently rotating the jack and the wheel supported thereon for placement on the rails. In carrying out this operation, it will be npted that the handle 3. is alays available forreacly operation use to t e rotation of the jack onthesupporting plate 11 which maintains the same relation between the operating. parts. of: the jack and the wheel structure, in order that the rotation of the wheel will not overlie the operative parts of the jack structure, and thereby prevent sufficient operation thereofl The latch member 18 serves to permit the rotation'of the jack through an arc of 90 in view of the positioning of the recess 6 so that when properly placed itwill stop the rotation of the jack with the Wheels carried thereby in proper position for placement 'on the tracks when moving these wheels from the dotted line position shown in Fig. 1.

This only'illustrates one application of the invention in connection with its use in repairing and replaein parts in railway rollin stock, while anot ier ready use is em hodie 'in reversing the positions of trucks underthe ears, or in removing and replacing these trucks in the repair oi the cars or ot'the rollingstock along 'a railroad.

Having thus described-"our invention, what we claim as new is A device of the class described comprising a jack having an annular base formed thereon provided with a centrally disposed annular boss on its undersurta'ce, an annular supporting plate having an annular upstanding wall at its outer edge within which the base is snugly fitted for rotation therein, said plate having a central recess adapted to snugly receive the boss of said base and cooperating with said upstanding wall whereby 'to' provide a double bearing support for the base against relative'transverse movement with respect to the plate and a latch member pivotally mounted intermediate its ends upon said plate with one end ofisaid latch engageable with the base for retainingthe same against rotation and spring means engaging the opposite end of the latch normally urging the same in base engaging position.

In testimony whereof we afiix our signatures.
