IMPROVEMENT IN MODES OF OBTAINING MOTIVE POWER.l

Specification forming part of Letters Patent No. 159,660, dated February 9, 1875; application filed November 24, 1874.

To all whom t may concern:

Be it known that I, CHARLES FAIVRE, of Paris, France, have invented an Improved Mode of ObtainingMotive Power, of which 'the following is a specification:

The object of my invention is to utilize as a motive power the weight of pedestrians and vehicles as they move to and fro, and this object I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure lis a vertical section of the appaparatus, and Fig. 2 a plan view.

A is a platform, supported by springs, which rest on the cylinders I, and is kept in place by rods C. Boards B and B', hinged to each end of this platform, connect it with the level of the roadway or foot-path. To the under side of the platform A are attached pistons F, (four in the present instance,) which are adapted to the cylinders J, and-are provided with the valve G, opening downward. Each cylinder, where a valve, J ,is open, communicates through the pipe K with the air-engine L, the piston of which is connected by a rod to that of the pump 0, which pumps air through the pipe R into the reservoir S.

The distance which the platform A is maintained by the springs E above the tops of the cylinders I should be about equal to the length of the stroke of the pistons F.

The platform A, and the number and size of the cylinders I, should be in accordance with the duty which they have to perform. Theymay be adapted to door steps, sidewalks, rooms, stores,&c, andfor vehicles on streets, roads, &c., for railroad-trains, at stations on the track, and wherever it may be thought convenient.

When a body passes over the platform A it will depress each of the pistons F, and force the air in the cylinders I to open the valves J, and escape into the pipe K, whence to operate the engine L. When the platform A is released from the passing' weight the pistons F will spring back to their original positions, and allow the cylinders to be again filled with air through the valve G. The valves J will at the same time close and retain the com p ressed air in the pipe K. The piston of the engine L, being operated by the vair compressed in the pipe K, will in turn operate the pump C, which pumps air or other fluid into the reservoir S. The cylinders I may, if desired, be in direct communication with the reservoir. This reservoir is open at the bottom, and is fixed to a foundation or well, the lower end of which contains a supply of water, and the latter, as the air fills the reservoir, rises in the well and keeps the said air under a constant pressure. A pipe, T, at the upper end of the reservoir, supplies this compressed air to the neighboring manufactories, &;c., where some suitable motor is operated by it.

I claim as my invention- The combination of the yielding platform F, f

cylinders I, and pipe K, communicating with the cylinders and with an engine or reservoir, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES FAIVRE.
