STEPHEN BURDETT, OF NEW YORK, N. Y.

TURNING UP THE STEPS OF OMNIBUSES.

Specification of Letters Patent No. 7,591, dated August 2'7, 1850.

T 0 all whom/2'15 may concern Be it known that I, STEPHEN BURDE'IT, of the city, county and State of New York, have invented a new and useful improvement on the steps of omnibuses and other carriages conveying passengers, itturmng up the step by the action of a spring, and in combination with a brake for stopping the carriage operated by the drivers foot; and I do hereby declare that the followlng is a full and exact description.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation, reference being had to the annexed drawings, making part of this sepcification, and accompanying model, for the better understanding of the same, in which Figure 1 is a plan, and Fig. 2 is a side elevation of the apparatus.

The same letters refer to the same parts in both views.

A, A, front upright lever movable on its joint near the center of its length, and operated by the drivers foot while seated; N, N, being the drivers foot board as usual; B, B, fore coupling rod connecting upright lever with the cross lever C,G, moving on its joint pin'fastened to the underside of the bottom of the carriage; D, D, the brake shackle jointed at one end to the short arm of the cross lever C, and at the other end jointed to the brake bar E, E; the brake bar is strengthened by a brace F, F, and is kept in proper position by its guide rod G, G, passing through the guides O, O; the brake bar carries on each end the brake blocks H, H, which are partly sustained by the springs 72, p, fastenecl to the spring bar R, R; J, J, hind coupling rod jointed at one end to the cross lever C, and passing through the spring case T, T,'and spring S, S, has a joint on the other end coupled to the step shank L, L',,which connect withthe short lever Q, Q, fastened tothe step K, K, of the carriage and turns it up moving on its joints, as soon as the driver takes his foot off the upper end of the front upright lever, and the passenger leaves the step.

I do not intend to restrict myself to the use of spiral springs, but I prefer this arrangement for convenience.

I do not claim the brake, nor the action of levers connecting it with the foot of the driver; but

hat I claim Is the turning up of the step (it being properly prepared for the purpose) by the action of the spiral, or other spring upon the stepping olf of the passenger, and the withdrawing of the drivers foot, and its connection with the brake apparatus; thus preventing boys or others from riding on it; the whole being attached to the body of the carriage, and operating substantially as fully set forth in the accompanying drawings and model.

New York, 1st June, 1850.

STEPHEN BURDETT.
