ARRANGEMENT OF SPRINGS FOR VEHICLES.

Specification of Letters Patent No. 16,625, dated February 10, 1857.

To all whom it may concern:

Be it known that I, DARIUS BABOOCK, of Homer, in the county of Cortlandt and State of New York, have invented a new and useful Improvement in Springs for Vehicles; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which,

Figure 1 is a side or face view of my improvement. Fig. 2 shows a modification of the same.

The invention consists in combining two Csprings with a sinuous spring, as will be hereinafter fully shown and described, whereby a cheap and durable spring is obtained, and the weight of the body of the vehicle made to bear upon the ends of the axles, instead of bearing upon their center portions, and thereby increasing the strength of the same.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A, repfesents the axle of a vehicle; and B B represent two springs, which are known as C-springs. The lower ends of these springs are attached one at each end of the axle A. The springs B are each formed of two leaves, (a) (b), the ends of which are connected together; the outer leaves (1)) having a quicker curve than the inner leaves (a), so that a suitable space is allowed between them.

The upper ends of the springs, B B, are connected by a sinuous spring D, which is formed of a single plate. The form of the spring D is plainly shown in the drawing; the outer portions or ends (0) (a) being curved to correspond with the upper parts of the springs, B B; the center portion (d) being curved in an inverse manner.

The outer ends of the springs B B, have each a curved bar, E, attached to them; said bars being connected to the body of the vehicle; which consequently, is supported by, or rests directly upon, the springs.

Fromthe above description of parts, it will be seen that the spring, D yields or is elastic longitudinally or lengthwise, and serves as a support to the springs B, B. And as the bars E are not jointed, but are perfectly rigid, the springs, B B, and D, are each subjected to their proper share of the weight or pressure; for the outer ends of the springs, B, rise and fall vertically, as shown in red, Fig. 1, and, consequently, the spring, D is acted upon longitudinally.

The C-spring is usually connected with the body of vehicles by means of straps, and these springs have also been connected to semi-elliptic springs by means of ointed bars or connections. These jointed connections allow the Csprings to be compressed, or to yield in a spiral direction; this will be understood by referring to Fig. 2, in which the bars, E, are jointed, and thereby allowed to give, or turn, so as to conform to the action of the C-springs.

It will therefore be seen that in my improvement, it is essential to have rigid bars to serve as connections between the ends of the springs, B, and the body of the vehicle, in order that the springs, B, and the spring D, may be properly acted upon and each subjected to its proportionate share of the weight, and a strong, durable, and elastic spring be thus obtained.

I am aware that combinations of C- springs and semi-elliptic springs have been previously used; I therefore do not claim the combination of the C-spring with other form of spring, irrespective of the peculiar form and arrangement as herein shown, to produce the result described.

hat I do claim, therefore, as new, and desire to secure by Letters Patent, is

The combination of the C-springs, B B, and sinuous spring, D, connected by rigid bars, E, to the body of the vehicle, substantially as shown and described.

DARIUS BABCOCK. l/Vitnesses GEORGE Ross, ALPHoNso STONE.
