WHEEL-PULLING DEVICE.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed larch 6, 1916. Serial No. 82,375.

To all whom it may concern:

Be it known that I, WALTER I. Tn'rrm, a citizen of the United States, and a resident of Providence, county of Providence, and State of Rhode Island, have invented an Improvement in Wheel-Pulling Devices, of which the following is a specification.

This invention relates to pulling devices and with regard to certain more specific features to devices for pulling wheels from axles.

One of the objects thereof is to provide a device of the above type of simple and compact construction and ellicient action. Another object is to provide a device of the above type in which a high degree of force may be exerted without injury to the parts. Another object is to provide a device of the above type which may be cheaply made and which is nevertheless strong, reliable and effective in use. Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in. the structure hereinafter described, and the scope of the application of whichwill be indicated in the following claims.

In the accompanying drawing in which is shown one of various possible embodiments of this invention,

Figural is a sectional plan taken on the line 11 of Fig. 2;

Fig. 2 is a side elevation taken trans versely of Fig. 1;

Fig. 3 is a similar view showing the entire device mounted in position for use;

Fig. 41's an outer end view of parts shown in Fig. 3; and

Fig. 5 is a sectional view of certain parts taken along the line 5-5 of Fig. 2.

Similar reference characters refer to similar parts throughout the several views of the drawing.

Referring now to Fig. 2 of the drawing, there is shown a supporting device for attachment to the wheel or other part on which the pull is to be exerted. This device comprises a collar 1 split as at 2 in Fig. 1 of the drawing, and having its end portions provided with the lugs 3 which may be clamped together by a wrench through the screw 4 threaded into one of the lugs 3 as best shown in Fig. 4 of the drawing. The inner surface of the collar 1 is preferably tensions terminate in a nut 8 preferablyhexagonal in form as indicated in Fig. 4 of the drawmg. The extensions 7 merge into the nut 8 by means of the rounded shoulders 9 and their inner ends are curved into the collar 1 as at 10.

Slidably fitted within the in turned flanges of the parts 7 is a nut 11 for which these flanges form ways in the use of the device. This nut is threaded upon a screw 12 which passes freely through the opening 13 through the nut 8. This screw is provided with a squared head 11 and preferably with a tapered inner end 15 which in use rests against the part against which pressure is to be exerted, here shown in Fig. 3 of the drawing as the axle 16 of a vehicle. It may here be noted that the terms wheel and axle are broadly used throughout this description and the following claims to comprehend equivalent parts with which the device is suited for use.

In the use of this device, assuming that it is desired to pull the wheel having the hub 6 ofi the axle 16, the collar 1 is turned upon the hub until it makes a secure connection therewith as indicated in Fig. 3 of the drawing, this turning being brought about by shoulders 17 as indicated in Fig. 1 of the drawing. If, now, the wheel be not unduly tight upon the axle 16 a continued rotation of the screw 12 hearing against the axle will draw outwardly the entire device including the hub 6. If, however, the parts be so jammed in position that the wheel is not readily pulled outwardly, the outer rounded end of screw 14 is struck sharply with a hammer, this action tending to drive the axle inwardly with respect to the hub. It

is to be especially noted that any slight or even considerable movement of the screw 12 under the influence of hammer blows brings no strain upon the parts as the nut 11 also freely slides within its ways topermit movement of the screw without turning. Furthermore, if the hub be frozen in position, or otherwise so firmly upon the axle that it continues to resist outward pulling, the screw may be alternately hammered and the slack taken up by turning it within the nut 11 until the wheel is entirely withdrawn. The screw 4 is then loosened and the device removed, whereupon it is in condition for further use.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

I claim as my invention:

1. A wheel puller comprising in combination, a unitary device having a collar portion adapted to make threaded engagement with the hub of a wheel and a portion extending away from said collar portion, a member slidably mounted in said second portion or said device, and a member threaded through said slidable member and having a portion adapted to engage an axle and a portion by which it can be turned.

2. A wheel puller comprising in combination, three members, two of which are slidabl v related one to the other and the third of which is threaded to one of the first two, one of said members being adapted to engage the end of an axle and another of said members comprising a portion adapted to make threaded engagement with a hub upon said axle, an outer supporting portion, and a pair of connecting portions spaced one from the other to provide substantial openings upon opposite sides.

3. A wheel puller comprising, in combination, a unitary device haying a collar portion adapted to make threaded engage ment with a hub, an outer supporting portion and a portion formed to connect said first portions and shaped to provide an angular guide on its inner surface extending substantially parallel to the axis of said hub, a nut mounted to slide in said guide and held from rotation thereby, and a bolt threaded through said nut and positioned to engage an axle within said hub.

4. A wheel puller comprising, in combination, a unitary device having a collar portion adapted to make threaded engagement with the hub of a wheel, an outer portion and a pair of connecting portions spaced one from the'other to provide substantial openings upon opposite sides, a member slidably mounted in said connecting portions and held thereby against rotation, and a member threaded through said sliding member having a portion adapted to engage an axle in said hub and a portion by which it can be turned.

5. A wheel puller comprising, in combination, a unitary member having a split internally threaded collar portion, an outer portion and a pair of connecting portions spaced one from another upon opposite sides and formed to provide guides on their inner surfaces, a nut slidably mounted in and interlocking with said guide portions, a bolt threaded through said nut in position. to engage an axle in said hub and extending outwardly beyond said first member, and means adapted to clamp said collar portion of said first member about said hula.

in testimony whereof, I have signed my name to this specification this 25th day of February, 1916.

WALTER ll. TUTTLE.
