Application filed August 21, 1923.

L), and means for connecting the bushing and bearing means together for eii'ectively \,itliV drawing or placing a bushing in position.

A still further object oi the invention is to provide an improved tool of the above character', which will be durable and eiii ient in use, one that will be simple and easy to manufacture and one which can be 'placed upon the market at a small cost.

`With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, in which drawings:

Figure 1 is a longitudinal sectional view through the Y tool showing the same arranged for extracting a bushing from a bearing.

Figure 2 is a top plan view ot' the tool.

Figure 8 is a transverse section through the tool taken on the line 3"-3 oit' Figure 1.

Figure 4 is a bottom plan View ot the tool.

Figure 5 is a diametric section through a portion of the tool utilized for engaging a bushing, Whenthe tool is utilized tor forcing a bushing into place, and

Figure 6 is a diametric section through the means for engaging the bearing, when the tool is used for forcing a bushing` into place.

Figure 7 is a side elevation ot a tool partially in section showing the same in position for extracting a bushing, and

Figure 8 is a similar view ,of the device shown in the operation of inserting a bushing.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A generally indi- Cates the improved tool, which comprises a longitudinally extending bolt 10 having one end thereof provided with male threads 11 and its intermediate portion provided Wit Serial No. 658,621.

a smooth bearing surface 12. rlhe end of the bolt 10 opposite to the end provided with threads 11 can be provided with a reduced polygonal extension 13 for perniiting the bolt to he engaged by a Wrench to prevent the turning o1 the bolt. rilhe smooth portion 12 ot the bolt 10 adjacent to the polygonal extension 13 is provided with an an nular groove 141, Vthe purpose o' which, will he hereinafter more iully described.

Threaded upon the threaded end 11 et the holt 10 is a relatively large manipulating nut 15 including the polygonal head portion 16 and a reduced axial extension or guide 17. A guide sleeve 18 ior the bushing and for engaging the hearing is provided tor receiving the bolt 10 and this sleeve is provided at its outer end with an internal shoulder 19 `for engaging the cylindrical extension or guide 17 on the nut 15. A suitable tl bearing 2O is adapted to he interposed between the polygonal head 1G of the nut and t-he inner end oi the sleeve 18 and this thrust bearing can be held in place on the extension 17 in any preferred wayi such as by a ring 21 or by forming shoulders directly on the extension.

An annular member 22 is provided for engaging the bushing, when the tool is to he used for extracting bushings from bear' and this member 22 is held in place hy a suit.- able split annular retaining ring 2S having a reduced necl openingy 24 for permitting the slipping ot the ring in place in the groove portion 14 of 'the bolt 1U. This ri 23 is provided with a reduced extension 25 for fitting into the bushing engaging meinber 22. Y

`When the tool is to be used :tor entr-acting bushings the smooth portion ot thi` bolt 1L is slipped through the bushing and the inner end of the sleeve 18 is placed in engagement with the hearing. The bushing engagingmember 22 is now slipped on the bolt 12 ant held in place by the ring 23. The nut 15 is now rotated by a suitable wrench or the like which can be placed in engagement with thel polygonal head 16 of the nut. This nut is now rotated in such a manner as to draw the bolt 1() inwardly7 which will i'orce the inember 22 into contact with the bushing and gradually draw the bushing from out oi the bearing and into the sleeve 18.

When it is desired to use the tool for placing bushings in place, the member 22 and the sleeve 18 are removed from the itl (l tl bolt 10. il. bushing engaging' ineniber 2G is nnbnt'itnted ior the sleeve lo and the naine ineludea :u annular bod v tor receiving the @guide or ent'ensionl on the nut 15 and the bore ot the body is provided with u groove :2T Ytor receiving the retaining` ring :l or the ahouldern Yt'or holding' the thrust bearing` 2t) in place. The bushingl engaging member 22 is nlo removed l'rom the bolt it) and an enlarged annular bearing;l tz'iignigi1n {Y member 3i) in substituted therefor. This bearing engaging; member 'ltl is prtnided with a bore Si `l'or permitting); the same to be Slipped upon the bolt it) und thin bearing' enfeaninir niemlfer llt) in held in place b v the retaining ring; ill, in the naine manne as the member 22.

.lin une oi' the tool Al'or puehing bear inge in place, the member in is placed on the extension li' and the bolt il is then slipped through. the hearing, the bushing haring been placed on the bolt in intimate eontact with the member 2o. The bearinpy engagging` member 3i) new placed on the bolt and held in plaee by the ringl Ql. The nut i5 in rotated by a suitable wrench, and the mein-- ber lo engaging* the bushing; wiil eti'eetivelv 'tort-e the name in plaee. it the bolt 10 has a tendenev to rotate with the nul i5, the bolt can be held against rotation by placingl :t suitable wrench on the polygonal extension 13 of the bolt.

Front the foregoing description, it can be seen that I have provided an exeeptionalli7 simple and durable tool 'for etieetirely extracting' bushings troni. bearings and for placing bushings in bearingal which will not injure the buhings in univ Wav whatsoever.

Changes in details may be made Without departing vii'om the Spirit or the aeope et this invention.
