Improvement in Springs for Railway-Cars.

HTTFTI UNITED STATES PATENT QFFICE.
TIMOTHY F. ALLYN, or NYAGK, NEW YORK, Assrenon TO COMBINATION OAR-SPRING COMPANY.
IMPROVEMENT IN SPRINGS FOR RAILWAY CARS.
Specification forming part of Letters Patent No. 129,448, dated July 16,1872.
To all whom it may concern:
Be it known that I, TIMOTHY F. ALLYN, of Nyack, county of Rockland and State of New York, have invented a new and useful Improvement in the Construction of Springs for Railway Cars, and designed especially for railway passengercoaches; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawing and to the letters and figures marked thereon, in which- Figure l is a perspective view of the spring and its several parts; Fig. 2, the end clasp and auxiliary rubber spring; and Fig. 3, the central housing and its India-rubber bearingsprings.
The nature of my invention consists in so constructing a steel-plate spring as to obtain the maximum elasticity and sustaining capacity of the materials employed.
To enable others skilled in the art to mak and use my invention, I will now proceed to describe its construction and mode of operation.v
E E E E are two sets of spring-steel plates, forming together a spring of elliptic form, the plates being held in position at their middle parts by the cast-iron housings D D D D, and at their ends by the wrought-iron clasps B B. The housings D D have India-rubber bearings (l O interposed between them and the springplates, which are held in place by recesses formed in the castings for that purpose. These housings are secured to the platesprings by the bolts G G, which pass through the space between the inneredges of the plates and also through washers resting or bearing upon the plate-springs; and have also projecting gibs or lips, which cover the edges of the plate-sprin gs and thus secure them from spreading outward. The end clasps B B are of wrought-iron, and have an iron bolt passing through them, as shown at F, Fig. 2, the ends of which bolt are riveted or barred up so as to secure the clamps together. These bolts also form bearings for the ends of both the upper and under plate-springs E E to rest against. There is also a second bolt passing through these clasps, which serve as carriers for the India-rubber auxiliary springs A A, between and near the ends of the plate-springs E E, which auxiliary springs, being within the end hearings or bolts F F, have the effect of shortening the length of the plate-sprin gs when they are loaded or submitted to sudden or severe strains, and thus greatly increasii'lg the sustaining capacity of the plate-springs.
I have herein described the end clasps as composed of two pieces of plate'iron each, and secured together by the bolt or rivet F; but if preferred they may be formed of a single piece of plate iron and have a central Washer on the bolt F to separate the spring-plates.
Having thus described my improved railway coach-spring, what I claim therein as new, and desire to secure by Letters Patent of the United States, is-
1. The combination of the spring-plates E E, constructed in the manner described, with the end-clasps B and bolts or rivets F F, in the manner and for the purpose substantially as described. i
2. I also claim the auxiliary springs A A between the ends of the plate-sprin gs, arranged in the manner and for the purpose substantially as shown and described.
