EBENEZER H. BOOTH, OF KIRKWOOD, NEW YORK.

VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 402,894, dated May '7, 1889.

Application filed January 28,1889- Serial No. 297,849- (No model.)

To all whom it may concern.-

Be it known that I, EBENEZER H. Room, a citizen of the United States, and a resident of Kirkwood, in the county of Broome and State of New York, have invented certain new and useful Improvements in Vehicle- Springs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the'same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is a bottom View. Fig. 2 is also a bottom view. Fig. 3 is a vertical section. Figs. 4 and 5 are details.

This invention has relation to vehiclesprings; and it consists in the novel construction and combination of devices, all as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letter A designates a wagon-body, and B the headblock or rear axle.

O O represent two spiral springs, which are coiled around the lateral branches d d of the equalizing-lever E, which is provided with an arm, g, projecting from its middle portion. The branches d d of the equalizing-lever are pivoted in boxes h h, secured to the bottom of the body, and these branches terminate in arms is k, which extend at right angles to said branches and parallel to the sides of the body, the branches d (1 extending just beyond the sides of the body, as shown in the drawings.

The inner ends of the springs O O, which are coiled in opposite directions, extend, in the form of arms m m, alongside the middle projecting arm, g, of the equalizing-lever, and are provided with eyes, through which a pin, Z, passes, said pin also passing through a bearing in the end of the arm g, so that the inner arms of the springs are connected to said arm. The outer ends of the springs are also extended, but in the opposite direction, forming arms a a, which are provided with end eyes and bolts, p, whereby they are secured to the wagon-bottom,additional fastening being usually employed in the shape of hook-bolts or loop-connections engaging the middle portions of the outer arms, or, of said springs. The ends of the arms is of the equalizing-lever are provided with eye-bearings s, for the attachment of links or shackles t.

The outer arms, a, of the springs are usually horizontally bowed, as shown, and extend near to the arms in of the equalizing-lever, as shown. The equalizing lever is free to turn in its bearings, being, however, controlled by the springs and the weight of the load in the wagon. To the link or shackle at the end'of each side arm of the equalizinglever is connected a short strap-fastening, F, which is formed with an eye, 2, to receive the boltw, which secures the strap-fastening to the head-block or rear axle, B. The middle portion of the equalizing-lever is connected to the wagon-box by a double loop or double bearing, 1, the loops or hooks of which pass around the lateral branches of said lever at the sides of the middle projecting arm, so that the equalizing-lever is held securely in position with regard to lateral movement, while it is allowed to turn, operating the spiral springs.

The springs, being connected to the equalizing-lever and to the body, are designed to act equally on each side of the vehicle, whether the load is centrally or laterally placed therein. Side rocking is obviated. The springs, being extended at their inner ends and attached to the middle arm of the equalizinglever, take the motion of the vehicle-body, when loaded, easily and securely.

Having thus described this invention, what I claim, and desire to secure by'Letters Pat ent, is

1. The spiral springs outwardly coiled around an equalizing-lever and having the inner arms connected to a middle projection of said lever and the outer arms secured to the vehicle-body, substantially as specified.

2. The equalizing-lever having the lateral pivoted branches, the side arms at right angles thereto, and the middle projecting arm provided with an eye or bearing at its end, whereby it is connected to the inner arms of the spiral springs around said lateral branches, substantially as specified.

3. The combination of the equalizing-lever having its lateral branches pivoted to the vehicle-body, substantially as shown and devehicle-body, its side arms provided with end scribed.
