SPRINGmVEHICLE.

SPECIFICATION forming part of Letters Patent No. 387,052, dated July 3l,

Application filed April 18, 1888.

To @ZZ whom it may concern:

Be it known that I, EDWARD CLIFF, of Rochester, in the county of Monroe, in the State of New York, have invented new and useful Improvements in Spring-Vehicles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of springvehicles in which the body is supported by a torsion-spring secured to the under side of the body and coupled to crosssprings mounted on the running-gear of the vehicle; and the invention consists in a novel construction of the component parts of the spring individually considered, and in a novel combination of said parts, as hereinafter fully described, and specically set forth in the claims.

In the annexed drawings, Figure l is an in verted plan view of a vehicle-spring embodying my improvements. Fig. 2 is an end elevation of the same. Fig. 3 is an enlarged longitudinal section on line .t x, Fig. l. Fig. 4 is an enlarged transverse section on line y y, Fig. 1. Figs. 5 and 6 are enlarged detail views of the V-shaped bearing of the torsionspring. Fig. 7 is a sectional view of the coupling ofthe body-supporting arms to the crossspring, and Fig. S illustrates a modification of the form of the torsion-spring.

Similar letters of reference indicate corresponding parts.

A represents the body of the vehicle, D D the cross-springs mounted, respectively,on the hind axle and head-block ot the running-gear.

C denotes the torsion-spring secured to the under side of the body, and ff are the coupling-arms connecting the torsion-spring with the crossspring. rFhis torsion spring is preterabl y composed of a central bar, a, U-shaped loops b I) at the ends of the bar c, and extending at right angles therefrom and in one and the same direction, and the arms c c extending from said loops and parallel with each other, all formed of a continuous bar of springsteel. Said torsion-spring is disposed with its armscc lengthwise of the body, in the usual manner, and is rigidly secured te the under cl, interposed be- A, and provided Afitted closely to the exterior side of the body by a shoe, tween the loop Z1 and body with a flange, d',

of the loop, as shown in Figs. 3 and 4 ofthe drawings. A clip, c, is placed astride the loop b and rigidly secured to the shoe d by a studpin, e', projecting from the clip and passing through the shoe and riveted on the latter, and thus the loop is firmly heid in the shoe d. By means of bolts r r passing through the clip and shoe and through the frame A of the body A, the loop l) becomes firmly attached to the body. I do not, however, limit myself to the aforesaid construction of the torsion spring C of one continuous bar, inasmuch as I can obtain the same or nearly the same effect by forming said spring in ti 'o pieces, each formed with the loop I), from which is extended one of the arms c, as before described, the loop in this case being prolonged and terminating near one side ofthe arm c, where it is rigidly secured tothe body ofthe vehicle, as shown in Fig. 8 of the drawings. The free end of the arm c ot' the torsion-spring I provide with a V-shaped edge or bearing, p, and between this bearing and body A, I interpose a bearingblock, t, which is rigidly secured to the frame A of the body, and is formed with a recessed bearing, t, preferably V-shaped, and of a greater angle than the V-shaped edge of the arm c. Although the said edge may be formed on a round bar, as shown in Fig. 6 of the drawings, yet to obtain this bearing in a simpler manner I form the torsion-spring C of a square bar and secure the same in its requisite position to bring one of the edges thereof to bear in the seat t by bending the loop b in a plane relatively diagonal to the shape of the bar, as shown in the annexed drawings. The arm c of the torsion-spring rocking on the Vshaped edge p completely obviates friction and liability of squeaking, and, inasmuch as said bearing is eccentric, the rocking ofthe arm c when subjected to strain causes the couplingarm f, which is rigidly attached thereto, to move longitudinally outward, and thus conformto the elongation of the cross spring D when subjected to a load. This harmonious movement of the coupling-arm f with the spring D allows me to attach said arm direct to the said spring. This attachment I prefer to make by forming the outer end of the arm f with ayoke, h, which projects from one side thereof and is formed with eyes i i, between IOO which is inserted the shackle-eye n, formed on the end of the spring, as illustrated in Fig. 7 of the drawings. A bolt, Z, passing through the eyes t t' and n, couples the arm to the spring. The bolt is provided with a nut, t, by the tightening of which the two eyes t' t' can be pressed closely against the end of the intervening shackle eye n, so as to take up the wear and prevent rattling. In order to guard against excessive pressureQbetween the aforesaid eyes, I form the bolt Zwith a shoulder, o, by which it abuis against the inner face of one of the eyes i. The central portion of the bolt I provide with a circumferential groove, Z', which serves to retain lubricant introduced in the shackle-eye n.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, 1s

l. In combination with the body and its supporting-spring, a rocking bar secured to the body and provided with a V-shaped bearing on the same, and a coupling-arm connecting said rocking bar with the aforesaid spring, as set forth.

2. In combination with the body, the torsion-spring C, formed of asquare bar bent into a U shaped loop, b, in a plane diagonal relative to the shape ofthe bar, the metal shoe d, interposed between said loop and body and secured to the latter, and the clip e, astride said loop and secured to the shoe, substantially as described and shown.

8. In combination with the loop b of the spring C, the shoe d, provided with the Bange d', and the clip e, provided with the stud-pin e', projecting from the clip and passing through the shoe and riveted thereon, substantially as described and shown.

4. In combination with the body A, coupling-arm f, and the spring D, formed with the shackle-eye n, the coupling-bolt Z, passing through said eye and through the end of the coupling-arm and formed with the circumferential groove Z', substantially as and for the purpose set forth.

5. In combination with the body A, the coupling-armf, formed with the yoke h and eyes t' i, the spring D, formed with the shackle-eye n inserted between the eyes i i, the couplingbolt Z, formed with the shoulder o, and the nut Z on the end of said bolt, substantially as described and shown.

6. In combination With the body A and spring D, the torsion-spring C, provided with the V-shaped bearingp, and the arm f, rigidly attached to said torsion-spring and coupled to the spring D, substantially as described and Shown.

In testimony whereof I have hereunto signed my name in the presence of two witnesses, at Rochester, in the county of Monroe, in the State of New York, this 12th day of April, 1888.
