VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 354,850, dated December 21, 1886.

' Application filed May .20, 1886. Serial No. 202,735. (No model.)

.To all whom it may concern:

Be it known that I, WILLIAM T. BEATY, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Re-enforcing Springs; and I do declare the following to be a full, clear, and exact description of theinvention, such as will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters and figures of reference marked thereon, which forms a part of this specification.

This invention relates to animprovement in springs for carriages, wagons, or other vehicles; and it consists in a re-enforcing spring and in the'construction, combination, and arrangement of the same with the parts of ordinary elliptic springs, as will be hereinafter fully described and claimed.

The annexed drawing illustrates the nature 7 of my invention.

A and B represent twosemi-elliptical springs, composed each of severalstrengthening-leaves securedtogether by bolts, as shown, said springs being connected together at their extremities by suitable devices, a, to form the ordinary elliptic spring.

0 represents the re-e'nforcing spring, which is interposed between the springs A and B, and which constitutes the essential feature of my invention. This spring, in general, consists of a single strip or leaf, although it may, conceivably, if so desired, be composed of several leaves. The spring 0 is secured at its middle portion to the lower spring, B, by means of a bolt, b, and clips 0 0, or other suitspring 0 are provided with clips D, which embrace the upper spring, A, toward the extremity of the latter; and, further, the spring 0 has a compound curvature in both directions from the middle portion, where it is secured to the spring B, said curvature being at first concave downward and then upwardly The terminal portions of the convex, so that theiend portions of the spring when they come into contact with the spring A will be approximately parallel thereto for a short distance, and the clips D will hold them together during the sliding movement due to their elasticity.

It will thus be seen that the spring 0 will re-enforce and strengthen the elliptical springs A and B, thus giving them greater power to sustain a heavy weight upon the carriage and yet without detracting from the elasticity of action, which enables them to lessen the jar incident to the saltatory and rolling motion of the vehicle and the inequalities in the road.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination,with anellipticalspring, of an interposed re-enforcing spring secured to the lower half of the elliptical spring and having its end portions in sliding contact with the upper half of the same, substantially as described.

2. The combination,with an elliptical spring, of an interposed reenforcing spring secured at its middle portion to the lower half of the elliptical spring and compoundly curved thence to each terminal portion, which portions are in sliding contact with the upper halfof the elliptical spring, substantially as described.

8. The combination,with an elliptical spring, of an interposed re-enforcing spring secured at its middle portion to the lower half of the elliptical spring and compoundly curved thence to each terminal portion, said terminal portions being in sliding contact with the upper half of the elliptical spring and being provided with clips which embrace the same, substantially as described, l I

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM T. BEATY.
