1 spring during removal, absence and replacement of the shackles. g I

An object is to provide a device which is simple, is easily and quickly applied and re moved by one operator and be a labor saver J over present systems for the same purpose.

Also to provide an object of low cost, of few and inseparable parts to avoid loss thereof, is light and rugged, and not cumbersome, thus forming a particularly practical too i for vehicle service institutions.

The invention contains certain advancements in this art as set forth in the ensuing disclosure and having, with the above, additional objects and advantages, and Whose construction, combination and details of means, and manner of operation will be made manifest in the description of the herewith illustrative embodiment; it being understood that modifications,variations and adaptations may be resorted to within the scope,

principle and spirit of the invention as it is more directly claimed hereinafter.

Figure 1 is an elevational view showing the applied device.

Figure 2 1s a perspective of the tool.

A portion of a rear, frame limb 2 is shown spring, one bar of the yoke being pivoted-so and under this is fixed a cross-spring 3 whose ends have eyes 4, only one being here illustrated as attached by a suspended shackle 5 to a perch 6 fixed on the axle 7 I The spring 'consists'of a bolster of leaves which are banded bya clip 8. r

The improved tool includes a U-shaped yoke one of whose side bars 10 is pivoted at 11 to the near end of the. cross-bar 12 whose V opposite end is rigid with the other side bar 13. Thus the side bars are relatively separable so as to be readily straddled over the frame limb 2.

The bar 13 turnably passes through a side 4 lug 15 of a wedge shaped chair block 16 whose inclined top more or less conforms to the bend of the spring 3. The opposite side of the chair has a lug 17 outwardly slotted at 18 to pass onto the respective side bar 10 of the yoke when this has been hung over the frame.

The lower ends of the yoke bars are threaded at 19 and have irremovable nuts 20.

After the yoke'has been hung on the frame I then the chair is swung around on bar 13 to close on the other bar and then the nuts 20 are run up until the chair sets hard against the spring and abuts the clip 8; this acting as a buttress for the chair. By using awrench on the nuts the chair is made to force back the spring. and slack the shackles so that its bolts or pins can be pulled'easily while the frame is jackedor hoisted for such operation. all of the time that it-is applied and thus allows replacement of the shackle without The tool holds the spring back -75 again going through the process of taking up the spring.

It will be seen that the bar 10 swings in the 5-29 1 plane of the yoke and into the open end of its respective lug of the chair.

What is claimed is 1. A vehicle. shackle releasing tool comprising a yoke having side bars adapted to be hung over a frame part and its subjacent as to be moved in the plane of the yoke to an. open po'sitiontofacilitateapplication of the yoke, and a chair and adjustable supports veesee therefor mounted on the side bars of the yoke for repressing the spring.

2. A shackle releasing tool comprising a U-shaped yoke whose side bars are provided with adjustable nuts and which is adapted to be straddled over a spring and frame assembly, and a chair having side lugs one of which is pivoted on one of said yoke bars and the other is laterally apertured to be swung against the other bar; the nuts being engageable with the lugs tovrepress the spring resting on the said chair.
