` further object of the invention tov provide a link mechanism whereby a device ot' standard size may be applied to wheels of varying 'diameter7 the range of adjustnient, however, being ordinarily sutiicient for gear wheels of the size usually employed in automobile or truck transmissions.

Improvements in the details of construetion of wheel pullers and their positiveand .certain operation are also among objects 4of my invention and will become apparent on reference to the following specification which describes the invention in connection with the accompanying drawings.

In the drawings: Figure l is a perspective view of the preferred form of my invention-applied to thel wheel ot' a` motor vehicle.

Fig. 2 is a' perspective view showing the application of the preferred form of my invention to a gear wheel.

Fig. 3 is a longitudinal sectional view of the ulling device.

-l is a detail view of one of the sectional links.

Fig. 5 is a bottom plan view of the spider.

Fig. 6 is a sidey elevation of a modified form of my invention applied to the wheel of a motor vehicle.

Fig. i is an end view of the modified form illustrated in Fig. 6.

Like numerals represent corresponding parts'fthroughout the several views of the drawing.

T he numeral l() designates a spider having a sleeve extension l1 and pairs of spaced lugs l2. The sleeve 11 is hollow and threaded internally for receivii'ig the threaded pressure-.applying member 14 having the s nare head 15 and the rounded Vend l@ vv ich is alsopreferably hardenedso as to prevent its deformation.l The sleeve ll also provided with external threads 125 for a purpose which will hereinafter appear. The end 16 of the pressure-applying member 14; is adapted to engage against the end of Specification of Letters Patent. Patented JApr. 2G, 1921.

the shaft 17 on which'the wheel, gear or. other niemberj is 'mounted' with sufficient 1 tightness as t'orequire the services of the wheel puller in the removal thereof.

Between thepairs of lugs l2 the spider isvslotted as at ll to rovide sufficient clearance for the operation of gripping levers 20.\. a

Levers 20 are inserted between theipairs of spaced lugs 12 and are pivoted therein by means of pins' 2l which pass throughregistering apertures in the levers and lugs and are riveted' over at theirende in'order.' to y secure the pins in place y In the preferred forni of wheel p'uller three pairsof lugs and three levers are shown. However, it will be understood that in some eases the limited space may not be sufficient for this number and in that case two pairs of lugs and two levers may -be used as illustrated in Fig. 6. The levers l20 are each provided on one side of the pivot pin with a relatively long arm terminating' in a hookshaped end 22, and With LL-short ar'rn on the other side of'the pivot terminating in a cam-Shapedsurface 23. A nut Qlis threaded on the external threads 13 and is formed with a polygonalhead suitable for wrench engagement and also with a curved surface complemental in shape to the cam'surfaces 22S ot' the levers.

The nut or. collar 24 may bc adjusted longitudinally by turning the* same `on .the threads 13 and its cam surface engaging 'With the cams Q3 will move the levers 2() simultaneously about their pivot pins 2l untilthe long arms 20 grip the wheel or gear or the link devices which are hercin- I after described.-

vW hen the wheel to be removed is of large diameter, such as the wheel of an automobile, T-shaped members are used equal in number to the levers o'f the pullingr device.

i Each of these T-shaped members comprises a casting having a cross-arm Q5 adapted to extend between and engage the spokes of the wheel and a central projecting 'portion Q6 connecting the cross-arm with the sectional .'li'nlr 27. The link is preferably formed of three sections denoted as 27', each section being separatedv by a'A webr'Bn which is adapted to4 engage the hook-shaped end of each "lever arm 20. It .will be seen.

y that; .these Tfshaped members ca n be readily cle, a

applied and detached from the spokes of the Wheel and that when inl operative position they extend downward so that the spread of the adjustable lever arms may be suilicient'.

both for large andl small Wheels.

In transmission mechanisms the space' is sometimes limited Vand will not pel-init the uSe"of three lever arms on'the pulling de?` vice. Therefore, lthe form shown in Fig. 67 -maybe used in which the structure is the same as above described with the exception that the spider 10 is equipped with two -pairs oflugsl",v andthese 'pairs are' arranged at diametrically opposite points. Fi-g. 6 shows the application of a tivo-arm 'Wheel beingr shown in connection therewith. a

. Assuming that 'it is desired to remove the Ivwheel illustrated in Fig. 1', the Tl-shaped elements are rst placed between the spokes -of the vvheel at'the proper angular displac'ef ments .to coi-respond with the angular posi'- tions of the arms 20. .The nut 244 is then turned So' that it Awill move longitudinally toward the wheel and engage the cam sur-A faces 23 thereby moving),r the gripping levers invard, until thcy'contact with the Web 28 of a sectional link. The nut 24 lis* then screived tightly in position, thus lockingr the gripping levers in engagement -W-ith the T-elem'ents.I Thel member 14 is then turned@ so that. its threaded connection with .the spider will ina-ke it approach the exposed 1 end of the shaft o n which the Wheel is danger ofthe gripping Llevers 'becoming mounted. After the hardened end ldcon-V tacts with the shaft a Wrench is applied t'o theI squared end. 15 of the pressure member and the reactive force will tend to nieve the spider 10 longitudilfiailyI away 4from ,the Wheel,` thus exerting a tensionstress on the spokes 'of the wheel through. the lever arms 20 and T-elements 26.. The turning of the member 14 is continued until4 the wheel is loosened and moved sufficiently on the' shaft so that the Wheel can loe-readily removed byl hand. During the operation, there is no firmly holds' them puller tothe wheel of a motor vehi-` shaped element and sectional links,

vehicle Wheel withA largif'e bearing surface 30 to thegear or link.

These hooks are connected by curved surfaces 31 to the main bodies ofthe levers and afford greater sectional area at the point of mavimum` st-res's andless unit pressure on the contacting si'rrfaces.

It will be seen thatmy invention provides a' simple', 'certain and economical means whereby Wheels or the like, mayv be readily removed from shafts and it is -app'arent that certain changes may be made in the, detail ,construction of the illustrated'form of m'y invention but all suchmodiicationsare' considered 4Withinfthe purview of my invention ifwithi'n the spirit Aand .scope of theapv ,pendod claims.
