BUSHING R MOVER, j

V Application filed December 28, 1925; Serial 110, 78,010. .1

A further object of the invention is the provision of a tool of the above character which may be quickly mounted in position in association with abushing for removal of thesameh i r 1 1 Still another object of the invention is the provision of an etlicient bushing removing tool which may be sold at a relatively low cost.

Other objects and advantages of the invention will become apparent as the description progresses.

In the accompanying drawing forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:

Figure 1 is a side elevational view ofmy improved tool shown in association with a sectional sleeve provided with flanged bushs t. 1

Figure 2 is a similar view of the tool partially in section shown operatively associated with a cylindrical form of bushing,

Figure 3 is a detailed top plan view of the tool elements in separated position,

Figure 4 is a transverse sectional view taken on the line 44 of Figure 2, and

Figure 5 is a fragmentary perspective view of one of the tool elements.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 10 generally indicates a bearing sleeve of conventional construction provided at its end portions with a pair of flanged bushings 11.

With particular reference to Figure 2, the numeral 12 designatesa bearing structure provided with a longitudinal bore in which is snugly fitted a cylindrical liner or bushing 13. The foregoing structure is well known in the art and forms no part'of the present invention, being merely illustrated to indicate the application of my improved bushing removing tool in connection therewith.

Referring now more particularly. to the structure embodying my invention, the numeral 14 designates the striking element of permit the tool, embodying a longitudinal rod of circular cross section slightly beveled. at one end-to provide a suitable striking surface 15. while theopposito extremity is out to form a tapered projection lfl of reduced size, providing a beveled face 17 at the inner portioniof the projection and a shoulder18 at the intermediate portion:otthebar." This member is forn'ied of a durable metallic bar slightly smaller 111 diameter than the'inner diantieterofthe bushing so. as to permit convenientengagement thereof;

Designed so as to be coeactively associated with the reduced portion 16 of the bar 14' is a key member 19 formed so as to be readily inserted through the bushing in an engageable-position with the bar. The key member is of semi-circular formation providing a rounded outer side of the same radial dimension as the bar 14 while the inner side provides a flat forwardly beveled side corresponding with the beveled formation of the projection 16. Formed on one end of the key member 19 is an eccentricflange 20,

particularly formed to engage the interior edge of the'bushmg, necessarily greater in diameter than the interior of'the bushing,

and less in diameter than the interior diameter of the sleeve. -7As shown to advantage in Figures 1 and 2, the shoulder 18 formed on the longitudinal bar 14 will engage the projecting flangeportion of the key member so that these members will be locked together in a bushing for removal thereof.

In use, to remove a bushing of the type il-- lustrated in Figure 2, the key member 19 is first positioned in the interior bore of the bushing with the projecting flange 20 ar- I ranged in contact with the exterior edge of l the bushing. The tapered projection 16 formed on the bar 14 is then'forced in thespace provided between the key member and the opposite Wall of the bushing sothat the shoulder 18 will be forced tightly against the flanged edge of the key member. The op posite end .of the bar. 14 is then struck with a hammer or other convenient tool and the bushing readily removed from the bearing by the force applied thereto. When em loying the removing tool in a bearing 0 the type illustratedin Figure 1, the key member is inserted so that the flange 20 will be disposed in the interior of the sleeve so as to engage the interior edge ofthe bushing 11. The bar, in this instance, is inserted 1n the that a simple and exceedingly efiicient'busheing removing tool has been devised, capable of application upon various types. of bushings and arranged to be conveniently transported.v An important feature of thepresent constructiomis the cheap construction, enabling the ordinary user of this type of tool to maintain a supply of tools of various sizes for convenient application on different sized bushings.

It is to be understood that the form of my invention herewith shown and described is to be-taken as the preferred example of the same, and thatthe construction is susceptible'of modification so: that changes as to the shape, and size may be resorted to Without departing. from the spirit of the invention or the scope. of the subj'oin'ed" claim.

bar of cylindrical form and uniform diameter for the major portion of its length, the bar at one end being recessed in one side to provide a: flat face inclined with respect to the axis of the bar and a shoulder at the inner-end of the faceextending substantially at right angles to the axis of the bar, and a key havinga transversely arcuate side of the same curvature as the bar and a flat side extending its entire length and inclined With respect to the axis of the-bar and to the same degree as the face of the bar, the said key having'its inner end transversely flat to engage the shoulder of the bar, and an eccentric outstanding flange at the inner end of thearcuate'side of the key'to engage the end of a bushing into which the said end of the bar and the key areinserted.

In testimony whereof I afiix my signature.

ELBERT I. THOMPSON.
