RICHARD H. DAVIS, OF SYRACUSE, NEW YORK, ASSIGNOR TO GHRIS'IOPHE O. BRADLEY, OF SAME PLACE.

VEHICLE-SPRING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 390,573, dated October 2, 1888.

- Application filed July 20.1888. Serial No. 280.525. (No model.)

To aZZ whom it may concern.-

Be it known that I, RICHARD H. DAVIS, of Syracuse, in the county of Onondaga and State of New York, have invented new and useful Improvements in AxleConnections for Vehicles, of which the following is a specification.

This invention relates to that class of vehicles in which the ends of the springs which support the body are attached to the axles.

IO In one construction the axles are bent or con structed with a depressed body and the springs are connected by shackles or loops with the ears at the inner ends of the axle-shanks. These shackles have heretofore been attached [5 t0 the axle by bolts passing through holes in the axle, but this construction is objectionable, as the connection .becolnes loose in course of time, causing it to rattle.

The object of my invention is to remedy this defect; and it consists of the improve ments which will be hereinafter fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is an elevation of an axle and connecting parts provided with my improvement. Fig. 2 is a fragmentary elevation of one of the end portions of the axle, the supportingspring, and the shackle onv an enlarged scale. Fig. 3 is a vertical longitudinal section of said parts.

Fig. 4. is a top plan view of the same parts.

Fig. 5 is a cross-section in line as 00, Fig. 3,

looking in the direction of the arrow. Fig. 6

is atop plan view showing a slightlymodified construction of the shackle.

Like letters of reference refer to like parts in the several figures.

A represents the depressed body of the axle, and a a are the raised shanks thereof, which carry the arms or spindles upon which the wheels are mounted.

B represents the semi-elliptical spring supporting the body of the vehicle and attached with its ends to the shanks a of the axle by loops or shackles 0.

Each shank a is provided on its upper side near its inner end with a transverse, recess or depression, (I, in which the adjacent cross-bar c of the loop 0 is seated, as clearly represented in Fig. 3.

0 represents a clamping plate secured to the upper side of the shank a and bearing with its free inner end upon the crossbar c of the loop, so as to hold the same in its seat. The clamping-plate c is secured to the shank a by a clip, f, surrounding the shank a, and a yielding filling-piece or cushion, 9, preferably of wood, interposed between the upper side of the clamping-plate and the bow or upper curved portion of the clip, as shown in Figs. 2 and 3.

The clamping-plates 0 may be made of steel or iron and are preferably constructed of untempercd steel. it represents depending lips or cars formed on opposite sides of the clamp ing-plates e and bearing against opposite sides of the shanks a, so as to hold the clampingplates against lateral displacement on the shank.

The clamping-plates chold the cross-bars of the shackles G in frictional contact with their seats at all times, and thus prevent rattling'of the shackles, and they are sufficiently elastic to allow the cross-bars to turn in their seats and permit the shackles to adapt themselves to the movements of the supportingspring B.

\Vhen the contact'surfaces of the loop and its seat become worn or loose, the play is readily taken up by tightening the clip.

The loops or shackles C may be formed in one piece and the end of the spring be bent around the adjacent end bar of the loop, as represented in Figs. 2, 3, and 4, or one of the end bars of the loop may consist of a removable bolt which passes through openings in the side bars of the loop and through an eye formed at the end of the spring, as represented in Fig. 6. a

I claim as my inventionl. The combination, with an axle provided with a recess or seat, of a shackle arranged in 0 said recess or seat and a clamping-plate attached to the axle and bearing upon said shackle, substantially as set forth.

2. The combination, with the axle provided with a recess or seat, of a shackle or loop 5 seated in said recess or seat, a clampingplate bearing upon said shackle or loop, a clip whereby the clamping-plate is secured to the axle, and a cushion interposed between the clip and the clamping-plate, substantially as 1888.

set forth.

3. The combination, with the axle provided with a recess or seat, of a shackle or loop seated in said recess 01' seat and a clamping- I plate bearing upon the shackle and provided at its ends with lips bearing against the sides of the axle, substantially as set forth.

Witness my hand this 16th day of July, 10

RICHARD H. DAVIS.
