IMPROVEMENT IN CHILDRENS CARRIAGES.

Specification forming part of Letters Patent No. 157,604, dated December 8, 1874; application filed August 14, 1874.

To allwhom it may concern:

Be it known that I, FRANCIS L. HUGHES, of the city of Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Perambulators; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, in Which- Figure l is a side elevation. Fig. 2 is a rear elevation.

My invention relates to the rear springs of a childs carriage. Such springs have been constructed in a great variety of forms, and, among others, scroll-springs have been employed, connected by a stiffspring-bar across, the ends of the spring-bar being attached to two sills which project back from the body of the carriage. This arrangement does not give freedom of motion required, especially in a lateral direction; and to obviate the difficulty my invention consists in combining, with the scroll-springs and the spring-bar, a half-elliptic cross-spring, intermediate with said parts, whereby the sills are dispensed with, and a greater degree of lateral motion attained, making the springs much easier in their action than usual. I

In the drawings, A is the body of the carriage; RE, the Wheels; G G, the front springs,

' and D D the rear or scroll sprin gs. The latter are attached at their front ends direct to the under side of the carriage-body, and at the rear the ends are bent or curved twice around, thereby forming the scrolls a a. The springs are attach ed to and supported by the rear axle J. E is the spring bar, and G is the half elliptic crosss'prin g, which forms the subject ofmy invention.

The ends of the cross-sprin g are riveted or otherwise attached to the inner ends of the scrollsprings a a, and in the center or convex portion it is bolted to the spring-bar, which it thus supports. The carriage-body, in turn, is attached to the spring-bar by the bodyloops 0 0, and the whole thus rests upon the cross-spring G and the coils a a. That portion of the crossspring which connects with the spring-bar rests in a concave socket, d, of the bar, as shown, by which means that portion of the spring is stiffened, while the ends thereof are free to yield either up or down.

By the means above described I produce a better action, especially in alateral or rocking direction, than can be produced by the attachment of the spring bar direct to the scroll-springs, since the cross-spring will yield either up or down independent of the scrolls, thus avoiding the arbitrary action where a stiff connection is used. The cross-sprin g also acts as a governor to prevent too much vibration to the scroll-springs. It produces a much more regular and easy action to the rear springs than can be attained by the devices before referred to.

What I claim is The combination, in a childs carriage, of the springs D, scrolls a a, spring-bar G, bodyloops 0, and the centrally connected crossspring, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

FRANCIS L. HUGHES.
