WHEEL-FULLER.

Patented Nov. 2, 1920.

Application filed September 20, 1919. SerialNo. 325,225.

To all whom it may concern Be it known that I, GEORGE E. FEssnNnnN, a citizen of the United States, residing at Rochester, in the county of vMonroe and State of New York, have invented certain new and useful Improvements in Wheel- Pullers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to a devicezfor ie I moving wheels, ball-races and the like, from the ends of shafts, and the object of the in vention is to produce a simple, compact, and inexpensive device capable of exerting a powerful pull against the article to be removed, and conveniently adaptable to wheels or articles of a variety of diameters and forms.

To the foregoing end the invention comprises a wheel-puller in which one or more divided sleeves are used, these sleeves being formed, at their ends, for engagement with the part which is to be pulled; in combination with means for clasping the parts of the sleeve against said part, and a device, such as a screw, for exerting pressure against the shaft on which the part is mounted.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which Figure 1 is a side-elevation of a wheel-puller with'its parts in cooperative condition; Fig. 2 is a side-elevation, partly in section on the line 2-2 in Fig. 1; Fig. 3 is .a section on the line 3-3 in Fig. 2; and Fig. 4 is a partial side-elevation, in section on the line 2-2 in Fig. 1 but on a larger scale than the latter figure, showing the wheel-puller as used to remove a ball-race from a shaft.

In the illustrated embodiment of the invention the wheel-puller comprises an outer sleeve 5, of. generally cylindrical form, which is divided longitudinally into two parts. At the upper'end the sleeve is provided with an inwardly projecting flange producing lips 6, and at the lower end with inwardly projecting lips 7. The sleeve'o constitutes means for engagement with the wheel or part which is to be pulled, and it cooperates with means for applying pressure to the shaft. These latter means comprise a body 8 which is perforated and screwthreaded to receive a screw 9. The lower end of this screw is provided with a part 10,

of reduced diameter, which engages the end of the shaft, and at its lower extremity the part 10 has a conical projection 11 adapted to enter a center-hole on the end of the shaft and thereby to maintain the parts, in correct alinement. The screw has a. flat head 12 at its upper end, by meansof which it may be turned. I

T he Body 8 has an outwardly projecting flange 13 at its lower end, and when the puller is imposition for use the two parts of thesleeve' 5 are clasped'around'the body,

so that the flange 13 is engaged and retained by the lips 6, as shown in Figs. 2 and 4, thus permitting the thrust of the screw to trans mit'tension through the sleeve 5 and the lips 7 to the part which is to be pulled, the lips 7 at this time lying beneath or behind such part.

The parts are retained in the position just described by means of a ring 14, which holds.

the two halves together as shown in the drawings. When the puller is to be applied to, or removed from, the part which is tobe pulled, the ring 14 is removed, and the halves of the sleeve may then be taken apart to permit the lips 'Z'to be suitably engaged with or disengaged from said part.

In order that the puller may be adapted foruse in pulling parts of several sizes and shapes, it is provided with a second or inner cylindrical sleeve 16, which also is divided longitudinally into two parts. At its re spective extremities the sleeve 16 has inwardly projecting lips 17 and 18, one pair of these lips being greater in radial dimen sion than the other, so as to provide for engagement with wheels, or the like, of two different diameters.

- A feature of the invention resides in its adaptation for pulling the inner races of ball-bearings of the separable type, such races being in the form, of rings with shallow peripheral grooves. For this purpose the lips 17 and 18 are convexly rounded, as shown, so that they may engage in the roove of a ball-race 22 mounted upon a shaft 20, as shown in Fig. 4:. To provide for a sufficiently firm engagement between the race and the lips, two screws 21 are threaded into the sleeve 5, and by tightening these screws the two halves of the inner sleeve 16 may be pressed forcibly toward each other, thus forcing the lips 1 and 18 firmly into the groove in the ballrace. lVith the parts g the puller may be adapted for use with parts of any desired number of forms or sizes.

.The inventionis not limited to the embodiment thereof hereinbefore described and illustrated in the accompanying drawings, but it may be embodied in various other forms within the scope of the following claims.

'The invention claimed is:

, 1; A wheel-puller comprising: a screw; a body in which the screw is threaded; a plu- ,rality' of members having inward projections, at their respective ends, for engaging, respectively, said body and the part which is to be pulled; and a removable ring adapted to embrace said members and to hold them in cooperative relation with said body and said part.

2. A wheel-puller comprising: a divided sleeve. formed, at its respective ends, for engagement with parts of different forms or sizes'which are to be pulled; means for holding the members of said sleeve in cooperative relation with each other; and means, cooperative with the sleeve when in either of its operative positions for applying pressure to the shaft on which is mounted the part which is to be pulled.

' 3. A wheel-puller comprising: a plurality of divided concentric sleeves provided, respectively, with inward projections of different forms or radii for engagement with parts, of different forms or diameters, which are tobe pulled; a removable member encircling the outermost sleeve and acting to secure its parts together in cooperative relation, and means, cooperative with the outermost sleeve, for applying pressure to the shaft on which is mounted the part to be pulled.

4. A wheel-puller comprising: a screw a flanged body in which the screw is threaded; a longitudinally divided sleeve adapted to embrace said body and having, at one end, an inward projection for engagement with the flange on the body and, at the other end, an inward projection'for engagement with the part to be pulled; and means for securing the members of the sleeve'together in cooperative relation.

5. A wheel-puller comprising: a plurality of members formed for engagement with the part which is to be pulled; means, cooperative with said members, for clasping them about said part and for applying pressure to the shaft on which said part is mcunted;

and a divided sleeve adapted to be embraced by said members and formed for pulling engagement with a part of difierent form or size from the part which said members are adapted to pull by direct engagement therewith. a

6. In a wheel-puller as defined in claim 5, screws, carried by said members, for forcing the parts ofsaid divided sleeve positively toward each other to cause them to engage the part to be pulled.
