Be it known that we, BENJAMI;Y iNsoN and Ronnirr A. TROBAUGH, citizens of the United States, residing in the city andv county of 'lulsa and State of Oklahoma, have invented certain new and useful lmproveiiient-s YVheel Pullers, of which the following is a specification.

rIhis invention. relates to'a tool oi' imple-V 'inent known generally as a wlieelpuller, but it is to be understood that this terni is not used in its restrictive sense, because the device is capable of utility for purposes other than conveyed by the expression, and the object of therinvention is to provide, in a manner as hereinafter set forth, a device ofthe characterreferred to, with mea-ns for removing wheels, gears, spindles, etc., and which will be as nearly universall as possibleinl respect to application of objects or elements of this nature of different shapes, construction. Y

A further object of the invention is to proin a -man'ner as hereinafter set forth, a device of the character referred to, with a plurality of removable clamping elements which can bereadily replaced when worn.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a tool or implement of the character referred to, which is simple in its const-ruction and arrangement, strong, durable,icoin pact, thoroughly efficient and convenient inv its use, readily set up, and comparatively inexpensive to manufacture.

lVith the foregoing and view, the invention consists lof the novel construction,'combination and arrangement ot parts, as hereinafter more specifically described drawings, wherein is shown an embodiment of the invention, but it is to be understood thatV changes, variations and modifications can be resorted to which come within the j j` ly referred to.' The forward end each ot scope of the claims hereunto appended.

Referring to the drawings in detail, 1 denotes a cylindrical tapering head piece, having formed integral with the end of larger diameter Vthereof four pair of substantially triangular-shaped arms", The arms of one pair are indicated 'at 2, 3,the arms of another pair at 4, 5, the arms of another pair at 6,

'7, and the arms of the remaining pair at 8,

9. The pairs of arms are Vradially disposed vwith respect to the head piece l, andthe arms of each pair are spaced from each other.- The outer corners at the forward ends of the arms 2, 33,

mergefrespecti'vely in the outer corners of s the forward ends of the arms 9, 4, as at 10'.' 1l. The outer corners at the forward ends of lthe-arms 5, 8, merge respectively in the outer corners of the forward ends of the arms 6, 7, as at 12, 13. of each of said arms are of greater width than the rear ends thereof and the outer edges of said arms form continuations of the outer periphery of the head piece 1.

The inner side of each of said arms, at its forward end, is formed with a rib 14'of a length equa-l to the width o-f the arm at the saidend, and said rib 14 forms a shoulder 15'. The ribs ofv each pair of arms oppose' The ribs of each pair of armsprovide a pair of combined guides and retainers for a clamping element to be presenttlie arms,'a t the outer side thereof, is pro` vided with an extension 16 of materially lessI width than the width of said end.

Formed integral Vwiththe forward end of each pai-r of arms,at the outer portion theren of, and extended forwardly therefrom is an apertured'bos's'whaving the wall of, its'Y open=` ng threaded. The said besace are dieA @sed at aight angles wat, respiri, to the *errant The forward ends vof the bosses.

edges of said arms, and the boss formed integral with the arnis 2, 3 is indicated at 17, that formed integral with the arms 4, 5, at 18, that formed integral with the arms 6, 7 at 19, and that formed integral with the arms 8, 9 at 20. The opening formed in caen of said bosses is indicated at 21. The outer side .of each boss is flush with the outer edge of that pair of arms with which it is formed'integral. rlhe extensions 16-of the arms are formed integral with the bosses and project inwardly therefrom. The extensions are of less height than the height of the bosses.

The bosses are connected togetherby a series of inclined brace members 22,23, 24

f and and. said brace members are formed integral with the extensions 16 and the sides rl`he brace member 22 is arranged between the bosses 17, 18, the brace member 23 between the bosses 18,19, the brace member 24 lbetween the bosses 19 and 20, and the brace member 25 between the bosses 2O and 17.

rThe head piece 1 is formed vwith a centrally disposed opening 26 having the wall thereof threaded, and extending through the opening` L6 and tlireadedly engaging withthe wall thereof is a forcing element having a plane cylindrical inner end 27 formed with an entering point 28, centrally thereof, and which projects forwardly therefrom. VThe forcing element further includes aninterlmediate peripherally threaded. portion 29 and a rear end portion 30 having a part thereof of polygonal contour, as indicated: at 31, for the reception of a suitable tool or` implement for adjusting the forcing element.

Threadedly engaging with each of the bosses is an adjusting member 32 formed,

with a peripherally grooved inner end por-V tion 33, a peripherally threaded intermedi-k T-shaped projection 40. The flanges 38 and i 39 provide means for connecting the clamping element tothe inner end portion of an adjusting member, andthe extension 40 prolvides means for slidably connecting the clamping velement to the ribs of a pair of4 arms when th.eclainping element is shiftedv by an adjusting member. In Figure 1 of the drawings, a pair of hub clamping mem-` bers is illustrated in clamping engagement with the hub 41 of a wheel mounted on a spindle 42, and with the entering point 28 of the forcing member seated inthe end of the spindle.

Nrlhe adjusting members provide means whereby the hub clamping elements can be employed 4with hubs of varying diameters.

lVlien the hub clamping elements are posi'- tioned in clamping engagement with the hub 41, the forcing member is adjusted inwardlv and such movement will provide for the pulling oil1V of the hub 41 from the spindle 42. A In Figures 4 and 5 of the drawings, there is illustrated a gear clamping element and when employed, the clamping elements are removed.

The` gear clamping element consists of an interiorly threaded socket forming member 43 peripherally grooved, as at 44, for the reception of a pair of opposed ribs 14. Threadedly engaging `with the member 43 is an adjusting bar 45 carrying a right angularly disposed'gripping linger46. The bar 45 is adjustable relative to-the member 43-V and is secured in adjusted position by a lock nut 47 carried thereby. r l

Figure 6 illustrates an attachment for eir-V tending the range of the puller beyond the radius of the bosses, and said device coinpriscs an arm 48 bifurcated at 49 and shouldered, as at 50, and which provides. means for connectingl a clamping element therewith. The arm 48 is foi'medwith a T-sliaped extension 51,adapted to` be connected with pair of. arms through the medium of the ribs 1 14. Vhen the attachment is in position, the

extension 51 abuts against the boss as shown in Figure 6, and the clampingelement cai'- ried by the arm 48 and which is indicated at 52, is arrangedexteriorly of and spaced from a boss.v

For pulling ofi7 timing gears that cannot be reached b-ya gear clamping element, andate portion 34 and a polygonal'-shapedV head The inner portion 33 provides meansv with such gears having an opening formed with threaded walls for the purpose of attaching bolts therewith to pull the gears, a, block 53 and a headed bolt 54 are employed. rlhe block 53 is positioned against. a. pair of ribs 14 andthe bolt 54 extendedthrough the bloclrand the arms with which the ribs 4are formed integra-l, and the bolt 54 is then se-A cured in the aperture. of the timing gear 5c.

After the clamping elements have been mounted in position, whether said elements be employed forl removing auton'iobile or other wheels, the forcing element is operated and which acting in connection with the yclamping elements will pull ofi' the wheel.

navarra increased, depending on thenumber of sides the main case. When removing truck wheels or for larger gears, preferably Vthe main case will be heX-agonalor octago-nal i-n contour.

The threadedhub clamping elements will be constructed ofvarying sizes'and with any number of threads to the inch as will suit the different requirements. The inner ends of the adjusting members will be constructed in any suitable manner to connect with the clamping elements to adjust the same,

but the connection will be such as to allow the adjusting members 'to rotate when shifting a clamping element. The reduced part on the outer end of the forcing member is placed there for the purpose of striking with a` hammer or sledge. A strong tension is had on the forcing member and in cases where the wheel or gear is exceptionally diicult `to remove, a blow with thefhammer on vthis reduced part will help to break the bond between the axle and hub. The forcing member is to be threaded any style, such as buttress, V, square, acme, etc., and any number to the inch as may be required by the nature of the work to be performed. The entering point on the inner end of the forcing member is for centering it on the end of the spindle or axle and tits in the lath center placed there for the purpose of machining the axle in manufacture.

lt is thought that the many advantages of a tool or implement, in accordance with this invention, and for the purpose set forth, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in the details of construction can be had which will fall within the scope of thev invention as claimed.
