Be it known 'th'a-t I, AUGUSTUS CAsE, a

"citizen of the United States, residinggat Tillamook, in the county of Till'amook and State of Ore on, have invented certain new and useful mprovements in Bushing-Removing Tools, of which the following is a I particularly to the-class of bushing remov- 111% tools.

he primary object of the invention is the provision of a tool ofthis character, wherein the bushings fitted within the/knuckles or king bolt sleeves of turning spindles of the front axles of an automobile can be readily removed with despatch, .the tool being of novel construction so that the same can. be applied within the knuckle or sleeve to en-.

gage the inner end of a bushing whereby it 'may be extracted by' a hammer blow upon thetool after its application, thereby facilithe tool.

tating the replacing of bushings by mechan ice in automobile repair .shops. I

Another object of the inventlon 1s the provision of a toolof'this character, wherein the same can be used by mechanics without ne cessitati'ng labor and trouble'ordinarily experienced when attempting to remove. the

ing for. the removal ofthe' same bushings fitted withinthe knuckle or king ing from said knuckle or sleeve, the fork of the front axle of said automobile being shown by dottedlines, while the knuckle or sleeve bushings and tool are shown by full lines and a portion of the tool being broken away.

Fig. '2 1s a perspective view of one part of Fig. 3 is a perspective view of the other part of said tool;

Fig. 4 is a fragmentary,"vertical, sectional view through the part of the tool shown in Fig. 2. I

imilar reference characters indicate corresponding parts through the several views inthe drawmg.

Referring to ignates a ortion of the wheel spindle and B the knuc le or king bolt sleeve thereof, which is adapted to be pivotally mounted in the fork end C of the front axle-of an auto- 'mobile in the usual well known manner and when It is required to remove the bushing .within said knuckle or sleeve *B the pivot bolt sleeve of a, wheelspindle of an automobile, the tool being readily adjusted to assure the positive engagement thereof with a bushwith despatch.

which is extremely simple inits construction, readily and easily applied to facilitate the easy removal" of a bushing, thorou hly reliable and efficient in its purpose, an "inex ensive to manufacture.

ith these and other objects in view the invention consists in the features of con-.

struction, combination and arrangement of arts as' will be hereinafter fully described, illustrated in the accompanying drawing and pointed out in" the claims hereunto appended. I I

In the accompanying drawing: Figure 1 is a vertical, sectional view through the spindle-knuckle or king 'bolt sleeve of the front axle of an automobile of a tool constructed in accordance with the invent-ion applied for the removal of: a bush- A still further object of the invention isv theprovision of a tool ofthis character,-

pin or king bolt (not shown) is removed.

from the-fork C'thereby detaching the knuckle or sleeve B for access to; the bushings 5 thedrawing in detail deswhich are pressed-into the said knuckle or a sleeve through the opposite ends thereof to assure a ti ht fit therein. I

The too for removing the bushings 5 from the knuckle or sleeve B comprises a of said tool and an adjustable wedge 7 constituting the other part thereof,.t shank atone end with a reduced or wrench "engaging tenninal 8 while the opposite end portion is bored and threaded to provide a threaded socket 9 o ning through said-end portion for adjusta ly'receivingthe reduced shank or'stem 6 which constitutes one part I I I lfibeing of the required length and is formed I threaded or screw end 10 of the wedge 7 I for a purpose presently described.-

- The socket end of the shank 6 is longitudis,

nally slitted as at 11 for a predetermined" distance at intervals circumferentially thereof to provide expansible or spreading fingers or jaws 12,,wh1le the wedge 7 at the inner end of the reduced threaded or screw portion 10 is formed with a beveled or tapered spreading surface or shoulder 12 to act w en the screw 10'is engaged in the socket 9 for the expanding or spreading of said jaws or fingers 12, which are normally conplon the fingers or jaws 12 of the shank 6 ice tracted, whereby they will be in position to have an external diameter corresponding to the diameter of the solid portion of the shanki 6, and the expanding or spreading position of the fingers or jaws" 12 will enable the abutment thereof with the inner end of either bushing 5 when in the knuckle or sleeve B to permit the removal of said bushing therefrom. The wedge 7 near its outer end portion is formed with a suitable hole 14 transversely therein to receive a spanner or key to permit the easy rotation or turnin thereof when engaged with the part 6 of the tool.

In the use of the tool the parts 6 and 7 are separated, the jaws or fingers 12 being normally contracted as shown in Figs. 2 and 4 of the drawing and the said part 6 is inserted through one of the bushings 5 in the knuckle or sleeve B and thereafter the wedge 7 is inserted in the other bushing to have its screw 10 engaged in the threaded socket 9 whereupon the wedge 7 is rotated, while the shank 6 is held stationary, thus causing the shoulder 13 to act upon the fingers or jaws 12 for the expanding or spreading thereof to the extent shown in Fig. 1 of the drawing for the abutment of these fingers or jaws 12 with the inner end of the bushing 5 to be' removed and finally a hammer or other striking implement is manipulated to impart a blow to the shank 6 whereby the bushing 5 abutting the fingers or jaws 12 will be extracted to remove from the knuckle or sleeve B, while the other bushing 5 can be readily removed either by the tool or other implement as will be clearly apparent.

From the foregoing it is thought that the construction and manner of use of the tool will be clearly understood and therefore a more extended explanation has been omitted.

What is claimed is:

1. A tool of the character described, comprising two parts, one of said parts being formed with a threaded socket, expansible fingers concentric to and projecting beyond said socket, and an adjusting screw formed on the other part for engaging the threaded socket and having a tapering shoulder at its inner end for action upon the fingers to spread the same on adjustment of the scre\ in the socket in one direction.

2. A tool of the character described, comprising a member having expansible fingers at one end thereof, the said member being formed with a threaded socket and located centrally relative to said fingers, and an adjustable member engaged in the threaded socket and having a tapering shoulder for co-action with the expansible fingers to spread the same on adjustment 'of said adjustable member.

3. A tool of the character described, comprising a shank having a tubular end portion longitudinally slitted to provide expansible fingers, the tubular end portion being internally threaded to provide a socket and an adjustable wedge for co-action with the expansible fingers and having a threaded portion engageable in the socket in said shank.

In testimony whereof, I hereunto aflix my signature.
