UNITED. STATES PATENT O FICE.

VEHICLE-SPRING.
SPECIFICATION forming part of Letters Patent No. 392,408, dated November 6, 1888.
Application filed June 26, 1888. Serial No. 278,258. (No model.) I
To aZZ whom it may concern:
Be it known that I, DALLAS P. CLARK, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Vehicle-Spring, of which the following is a specification, reference being had to the accompanying drawings.
My invention relates to springs formed of round or fiat steel-wire rods or bars, which when in useare subjected to a bending strain, as in elliptic springs, and as distinguished from the twisting or torsional strain to which the wire of spiral or coiled wire springs are exposed.
Iwill proceed to describe the improvement, and point out its novel features in claims.
In the drawings, Figure 1 represents a wagon-bolster and a bar parallel therewith between-the stakes having a double spring embodying my improvement at each end between the bar and bolster; Fig. 2, an end View of the same bolster, bar, and double spring; Fig. 8, an under side view of the same bar and the springs attached thereto. Fig. 4 represents an under side view of a similar bar and springs, showing a modified form of the connection of the springs with each other and their attachment to the bar. Figs. 5, 6, and 7 represent details of Fig. 4 on an enlarged scale.
Like letters of reference indicate corresponding parts inall the figures.
The spring A is formed of a single pieceof flat, round, or square steel-wire rod or bar, and is bent at or near its middle, forming a loop, a. The parts of the wire rod or bar between its middle and ends cross each other, giving to the loop a a circular or elliptical form, and each of the said parts terminates in parallel lugs b and a, formed by bending one end of the wire rod or bar to the right and the other end to the left across the plane of the loop a and in a direction perpendicular to that plane.
I unite or connect two or more springs, a, rigidly together, forming thereby a double 7 spring, as represented in all the figures of the drawings, by a connection, B, uniting, forming, or connecting the lugs 11.
In Figs. 1,2, and 3 the connection B is represented as consisting of an intermediate or connecting part, h, of the same piece of wi re of which the two springs A thus joined are I formed, joining the extremities of the lugs b with each other.
In Figs. 4, 5, 6, and 7' the connection B is represented as consisting of a grooved plate, (I, and a grooved cap, e, into the grooves f of which the lugs b are placed, being firmly and rigidly clamped therein by bolts and nuts 9, the double spring thus formed being firmly and rigidly attached to the bar E by the same bolts, 9.
In Figs. 1, 2, and 3 the double spring is attached to the bar E by a broad-headed clamp bolt and nut, i, and to secure the firmness and rigidity of the attachment the under side of the end of the bar is grooved to partially let in the lugs b and c and the connection B, which in such case is the part h of the same wire rod or bar of which the two springs A thus united are formed.
My improvement is particularly applicable to the seats and bodies of vehicles.
In the examples represented in the drawings, 0 indicates a bolster, such as is used in wagons to support the body or box thereof.
1) indicates the stakes between which. the body or box of the vehicle is carried.
E represents a bar over the bolster and parallel therewith, upon which the body or box rests, and between which and the bolster the springs A operate, the lugs Z) of the springs being rigidly attached to the bar, as hereinafter set forth.
The bar E in Figs. 1, 2, and 3 is represented as notched or bifurcated at the ends to embrace the stakes D, by which the bar is guided in its up and down movements. In Figs. 4, 5, 6, and 7 the plate (I is represented as similarly notched or bifurcated and for the same purpose. The lugs 0 rest upon the bolster G and press against the sides of the stakes D, as represented in Figs. 1 and 2. Vhen two pairs of springs A having my improvement are thus employed between the bar E and bolster G of of a wagon, the two springs of each pair are rights and lofts, but are otherwise exactly alike, and yield equally to the weight on the bar E, and the strain on the wire rods or bars of which the springs are formed is a bending strain, as distinguished from the torsional or twisting strain to which the wire bars or rods of spiral and other springs similarly employed are exposed.
Vhat I claim as new, and desire to secure by Letters Patent, is-
1. The spring A, consisting of a singlepiece of steel-wire rod 01' bar bent so as to form loops a at the end portions of the spring and an elliptical portion between said loops, the ends of the wire rod or bar being bent into parallel lugs 11 0, formed by bending one of the end portions of the rod to the right and the other to the left across the plane of the loops a and perpendicular to that plane, substantially as specified.
2. The combination,with the bolster (.7, stake D, and the bar E over the bolster and parallel therewith, of two springs, A, each consisting of a single piece of wire, and having a loop, a, and lugs 11 and c, as set forth, the connection B, formed of a plate, (I, and a cap, a, having 20 DALLAS P.
