VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 340,036, dated April 13, 1836.

Application tiled January 14, 1886.

To all whom it may concern.-

Be it known that I, ADAM EDELMANN, of Germantown, county of Columbia, and State of New York, have invented a new and Improved Spring for Lumber-\Vagons and other Vehicles, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved spring for lumber-wagons and other vehicles, which spring has a free and easy movement with a light or a heavy load, and which can be placed on the vehicle or removed from the same'at pleasure in a very few moments.

The invention consists of a sp ring com posed of two convex members, which are centrally united at their respective backs.

The invention also consists in the construction and arrangement of parts, as will be here inafter fully described and claimed.

Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of my improved spring for lumber-wagons and other vehicles. Fig. 2 is a plan view of the same, parts being broken out. Fig. 3 is a perspective viewof a modification.

The spring A consists in two convex members, B and (J, which are centrally united at their backs by means of bolts D or other suit-- able devices. Each member B and C may be provided with one, two, or more plates, B and O.

The ends of the upper member, B, of the spring A are provided with recesses E, and the lower member, 0, is provided at each end with two downwardly-extending lugs, F. The

spring A is placed on the bolster G in such a manner that the outer ends of the member 0 ride on the upper edge of the bolster G, being held in place on the bolster by the lugs F, which extend on each side of the bolster.

Serial No. 188,612. (No model.)

The recesses E of the upper member, B, fit 5 over the stakes H of the bolster, and thereby prevent a sidewisc movement of the spring, but allow a lengthwise expansion. The recesses E of the upper member and the lugs F of the lower member hold the spring A se curely in place on the bolster G.

The upper member, B, of the spring A may be square at its end, not having the recesses E, and be provided with a malleable-iron shoe, L'rivetcd or otherwise secured lo the ends of the member B, and having a recess, 1, similar to the recess E. This shoe can be adjusted at the ends of the member B to suit wagons having their stakes II a greater or less distance apart.

It will be seen that as the spring is not permanentlyfiistened to the bolster it can be removed from the same very easily and rapidly.

The ends of the lower member, 0, of the spring A may be clipped lengthwise to the axles oi" the wagon, and the upper member attached at the outer ends to the under side of the wagon-box.

Haying thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. A spring composed of two members centrally united at their backs, of which the lower member is provided at its ends with downwardly-extending lugs and the upper. member 7 is provided with recesses, substantially as herein shown and described.

2. The spring A, composed of the member B, having recesses E, and of the member 0,

having lugs 1*, said members being fastened
