rWHEEL Puri-LER.

Application inea March 1'2, 19271 serial No. 174,866.

The invention relates" to devices for pull#` ing wheels or other members from axles or shafts on which they are mounted, in cases in which they have been originally mounted on the shaft with a drive Vtit or,for any other reason,areN clitlicult to remove. More particularly, vthe invention relates to that type of puller in which a threaded ring, separate from the main 'body of the puller, is employed-- l The objectot the invention is to provide a puller or the type above specified, in which the ring may be irst screwed onto thehub of the wheel gear, or other object that is to be removed from a shaft, and the body of the puller then placed over lthe ring and iixed .in position'tor pulling.' According to the invention, the threaded ring provides peripheral recesses and projections, and a member carried by the body of the puller, or a portion thereof formed integral With it, provides interlocking internal recesses and projections. Thus the body portion. of the puller may be slipped over the ring s which is already in position on the hub, and then turned slight-ly to lock it in position..

The wheel may now be removed by the use of a threaded bolt which reacts against the shaft, or a driving wedge, or any other known equivalent, may be employed as my invention relates to `the interlocking ring, and the interlocking member that coacts with it.

The above will be more particularly described in connection with the accompanying drawings, in whichy Fig. 1 is a. front eleva-tion of the puller, showing the ring in interlocking position.

F ig. 2 is a. longitudinal sectional View on the line 2 2 of Fig. 1.

Fig. 3 is a perspective view of the puller, the ring being removed.

F ig. l is a perspective vie-w of the ring, this figure being drawn on a larger scale than Fig. 3.

Like reference characters reiterl to like parts throughout the drawings.

Referring irst to Fig. 2, the body of the puller is shown Vat 1. As indicated in this ligure, the body portion 1 is cup shaped and provides an aXial hole 2 therethrough.v It also provides va cylindrical recess 3 of a larger diameter than the hole 2, which leaves an internal shoulder 4 for a pnrpose'to be described.4 The body port-ion 1 is externally threaded at 5 and a member 6 is screwed onto it; this member can be fastened in any position of' adjustmentby means of a set screw 7 v Referring nonT toy Fig. 3, the member 6 provides a plurality of inwardly projectingv f portions 8 leaving a plurality of recesses '9;

The sectional View of Fig.' 2 is taken through the kproject/mgv portions 8, and it will be ob-y vserved fromv said ti'gure't'hat each portion 8 is bevelled as shown 'at 10. The `threaded ring 11 is bestshown iii Fig. 4l; it provides'a plurality of projecting portions 12 and receases-'13, the former having beve'lled .edges 14; The ring 11 lis split at 15 and provides internal threads 16.

Referring now to Figs. 1 and 2, a nut 17 is provided which removably'iits in the recess 3. A bolt 18, which is threaded as shown,l passes through the hole 2 andl through the nut 17. Pins 19, 19, located in the cylindrical recess 3 and extending into Y drilled holes in the body portion 1, prevent the nut 17 from turning when the boltis turned. A pin 2O extending forwardly-.troni the body portion 1 providesa limiting stop for the ring 11, engaging with the side of one of the projecting portions 12 when the ring is turned.

A plurality of rings 11 are preferably g provided, each ring having the same outer peripheral size and shape,fbut each ring having a different internal diameter to lit different sized hubs. A ring 11 having been selected that lits the threads on the hub of the Wheel or other article to be removed, it is screwed onto such hub. Assuming that the remainder of the puller has been assembled substantially as shown in Fig. 3, it may readily be slipped over the ring 11, as the projections 12 will pass through thev recesses 9 in the member 6. Vhen the member 6 has thus passed over the ring 11, the latter having come in contact with the body portion 1, the body 1 and the member 6 are rotated until the side of one of the projections 12 strikes the pin 20. The projections 12 are now behind the prgjections 8.

To remove the wheel, all that is now necessary is to turn the bolt 18. The front end of the bolt eventually contacts with theV shaft on which the wheel is mounted, and further turning removes the Wheel. It

necessary a blow can be given to the head of the bolt 18 without fear of stripping any threads, since the nut-can always'move forward in the recess 3. As the turning oi the bolt 18 pushes it against the shaft, the reaction on the nut 17 is taken by the shoulder, which draws the body 1 to the right, Fig. 2, this in turn drawing the member 6 in the same direction, forcing the beyelled por* tions 10 against the bevelled portions 14 ot the ring 11, which tightens the ring on the threaded hub by diminishing the size of the split opening 15. This very effectively pre-I vents strippingr the Vthreads either of the ring 11 or of the hub.

It should be noted that once the member 6 is properly adjusted on the body portion 1, the relative position of these parts never has to be changed, the only necessary adjustfv ment of the device thereafter consisting in the adjustment of the position of the bolt 18 in the nutl 17. The parts 6 and 1 are made separate merely for manufacturing reasons.

I claim,V

1. In apparatus of the class described, a

split ring, alternate projecting and recessed portions on the outer periphery of said ring,

and there being bevelled edges on said projecting portions, in combination with a hollow member, alternate 'projecting and recessed portions in the internal periphery of said hollow memb-enandthere being bevelled Vedges on said projectingfportions,'whereby portions on the outer periphery of said ring,

and there being bevelled edges on said projecting portions, ,in combination `Vwith a hollow member, alternate projecting and recessed portions in the internal periphery of said hollow member, there being bevelled edges onvsaid projecting portions, and nutV y' and bolt means for causing areacting thrust on said hollow member, whereby said ring and said membervmay be interlocked together with said bevelled edges in engagement` and the said thrust will compress the said split ring.
