Application filed May 7,

To all whom it may concern:

Be it known that T, a citizen of the United States,

Rnrns K. STARKEY, residing at Henne'ssey, in the county of Kingfisher and 5 State of Oklahoma, have lnvented certain new and useful Imp rovements in Bushing Removers, of which the following is a specification, reference panylng drawings.

being had to the accomremoving or replacing bushings in one of a plurality of alined openings.

An important object to provide a device 0 has means engaging of alined openings of the invention is If this character wh ch in one of a plurality for alining a shaft with the remaining openings, the shaft being provided upon opposite ends thereof with means for removing or replacing a bushing and means whereby the sh gitudinally in either A further object of vide a device of this 0 readily employed aft may be shifted londirection.

the invention is to proharacter which may be for removing the rear bushing of automobile engine cam shafts, and more particularly the rear cam shaft bushing of the engine at present in a Ford automobile and Fordson tractor.

Other objects and vention will become the course of the foll advantages of the inapparent throughout owing descrlptlon.

In the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein like reference characters designate like parts throughout:

Figure 1 is a side sectlon, showing a de elevation partially in vice constructed in accordance with my invention in use for removing a bushing;

Figure 2 is a similar view showing the device employed Figure 3 IS a tion of the operating shaf Figures 4: and 5 bushing, replacer Referring now mo for replacing a bushing; detail view partially in sect; and are side elevatlons of and remover respectively.

re particularly to the drawings, the character E designates an engine frame which in tion above referred the type of constructo embodies openings 10, 11 and 12 adapted for the reception of the bearings of a cam shaft not herein shown. The rear this constructlon is 0 bearing of the cam shaft in omprised in a bushing employed 1921. Serial No. 467,606.

13 which has a driving fit with the opening 12 and which is ordinarily difficult of access.

The numeral 1% indicates a shaft of less size than the openings 10, 11 and 12, and having one end thereof screw-threaded, as at 1%, the opposite end being adapted for the interchangeable reception of a bushing remover 15 and a bushing replacer 16. In the present instance the method of connecting the remover 15 and replacer 16 is shown comprising an internally threaded socket 17 formed in the end of the shaft 14: and adapted for engagement with reduced threaded extensions 18 formed upon these devices. The remover 18 has the body portion thereof tapered and formed like a tap, as indicated at 19, so that it may be readily engaged in the bushing 13 by rotating the bar. The replacer 16 is provided with a reduced extension 20 adapted to have a sliding fit in the bore of the bushing 13, which reduced extension forms ashoulder 21 upon the re placer adapted to engage against the end of the bushing in a solid manner to enable the bushing to be driven into its position in the opening 12. v

The threaded end 1 F of the bar 14; has slid-ably mounted thereon a member 22 having a sliding fit in one of the openings 10 or 11, preferably in the opening 10, as illustrated, to form a mounting and guide for the bar 14 so that the same may be properly alined with the opening 11 or 12 in which the bushing is to be positioned. This member has a shoulder 23 abutting the wall of the engine frame at the sides of the opening 10 and is adapted to be engaged by a threaded nut 24 mounted upon the screw threads 1 1 of the bar 14. The extremity of the threaded portion 14 of the bar 14 has rigidly secured thereto a wrench-receiving portion 25 wherebv the bar 1a may be rotated as a whole, and this wrench-receiving portion is provided with an extension 26 having a striking face 27 against which a hammer may be applied to drive a bushing into position. This extension 26 may likewise be provided with an opening 28 in which a bar may be inserted to rotate the bar 14 instead of employing a wrench upon the polygonal portion 25.

In the use of my device the bar 14: is inserted in one of the openings and the member 22 positioned in this opening, the bar having first had applied thereto the re- 1 do not limit myself to The bar is then slid through the member 22.nntil the bushing remover engages in the bushing to be removed and the bar 14 rotated to firmly fix the bushing re mover in said bushing. I The nut 24 is then rotated in engagement with. the shoulder formed by the member 22, drawing the bar through the member and drawing the bushing 13 from its seat. hen it is desired to replace the bushing the bar is positioned as above described, having first been provided with the bushing. replacer 16, and the bushing 13 is placed upon a reduced extension 20 thereof. The bar is then moved inwardly until the bushing 13 engages in the endof'the opening to which it is to be a plied, the nut 24 being shifted back or toward the end of the bar or away from engagement with the member 22. The bar may then be forced longitudinally by blows upon the striking face 27 thereof until the bushing 13 is seated. 7

Many changes being possible in the shape,

.size and arrangement'of the various parts 25' hereinbefore set forth without in any manner departing from the spirit of myinvention, I the specific structure thereof except as hereinafter claimed.

, lVhat'I claim is: v v

1. A device for removing or replacing bushings in one of a pair of alined openings,

comprising a member adapted to slidably engage in one of said openings and forming a guide, a bar slidably directedthrough said member and maintained thereby. inalinement with the other of said openings, said bar'being provided upon one end thereof with means whereby it may be rotated and adapted upon the other end thereof for the interchangeable reception ofa busliingreconsequently with-- mover or replacer, and means mounted upon the first named end of the bar for shifting the bar longitudinally through said member. 2. A device for removing or replacing bushings in one-of a pair of alined openings, comprising a member adapted to slidably engage in one of said openings and formin a guide, a bar slidably directed througl i said member and maintained thereby in alinement with the other of said openings, said bar being provided upon one end thereof with means whereby it maybe .rotated and adapted upon the other end thereof for the interchangeable reception of a bushing remover or replacer, and means mounted upon the first named end of the bar for shifting'the bar longitudinally through said member in one direction, the first named end of the bar is likewise provided with a' stril'e. ing face. I I

3. A device for removing from or replacing bushingsin one of a pair of alined openings, comprising a member adapted to slidably engage in one of said openings and having means limiting its movement therethrough,

1 I saidmember having one end thereof extera bar slidably directed through nally screw-threaded and provided with means whereby it maybe rotated, a nut havmg threaded engagement with said end and adapted to engage against said member, bushing removing and replacing implements, and coacting portions formed upon the other end of the bar and said implements whereby said implements may be in terchangeably secured to said end.

In testimony whereof I hereunto aflix mysignature.
