CHARLES A. GOULD, OF BAY SIDE, NEW YORK.

CAR-BUFFER.

SPECIFICATION forming part of Letters Patent N 0. 529,857, dated November 27, 1894.

Application filed May 26, 1894- Serial No.512,505. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES A. GOULD, a citizen of the United States, residing at Bay Side, in the county of Queens and State of New York, have invented a new and useful Improvement in Oar-Buffers, of which the following is a specification.

My invention relates to the supplemental bulfer devices which are employed principally in connection with freight cars, in addition to the ordinary or main buEer springs on the drawbar. V l

The object of my invention is to produce a simple supplemental buffer of this character which is readily applicable to ordinary cars without necessitating any changes in the construction of the same.

In the accompanying drawings consisting of two sheets: Figure l is a longitudinal sectional elevation of the draft gear of a freight car provided with my improvement. Fig. 2 is a top plan view thereof. Fig. 3 is a cross section in line 33, Fig. 1. Fig. 4 is a sectional elevation of a modified construction of the improvement. Figs. 5 and 6 are cross sections in lines 55 and 6-6, Fig. 4.

Like letters of reference refer to like parts in the several figures.

A represents the center sills of the car body and B the end sill.

O is the drawhead, O the drawbar and G the main draft and bufier springs which pref erably co-operate with two followers 0 0 connected with the drawbar by the usual tail bolt 0 This main spring mechanism may, however, be of any other suitable construction, as it forms no part of my invention.

D is a supplemental buifer spring applied to the drawbar in front of the main bufier springs O and bearing at its rear end against a collar or abutment E and at its front end' against the rear end of a sleeve or bushing F surrounding the drawbar. The collar E loosely surrounds the rear portion of the drawbar and abuts preferably against the same lug e which forms the stop of the front follower c of the main buifer springs. The drawbar slides freely in the sleeve or bushing F and the latter rests loosely upon the usual carry iron 9 secured to the under sides of the center sills, so as to permit the sleeve to slide inward and outward uponthe carryiron. The front end of the sleeve abuts against the upright rear end of the drawhead,

while the rear end of the sleeve is formed with a projecting flange f against which the front end of the supplemental bufier spring bears. The sleeve F is preferably rectangular in cross section to correspond to the flatsided form of the drawbar.

When the drawhead is moved inward by contact with the drawhead of an opposing car, the sleeve or bushing F is compelled to.

The latter is thus efiectually checked and prevented from striking against the end sill or bufier block with sufficient force to break it ofi the drawbar.

In the modified form of my invention represented in Figs. 4., 5 and 6, the sleeve or bushing F is formed integrally with the drawhead and projects rearwardly therefrom. The supplemental buffer spring bears in this case direetly against the rear end of the drawhead and the sleeve serves as a pocket which inoloses the spring.

I claim as my invention- 1. The combination with the car body, the drawhead, the drawbar and the carry-iron of the draw bar, of a sleeve surrounding the draw bar and extending rearwardly from the draw head and resting upon said carry-iron, a stop or abutment arranged in rear of said sleeve, and a bufier spring surrounding the draw bar and bearing at its rear end against said stop or abutment, substantially asset forth.

2. The combination with the car body, the drawhead, the drawbar and the carry iron of the drawbar, of a sleeve loosely surrounding the front portion of the drawbar and arranged to slide upon the carry iron, a lug or abutment arranged in rear of said sleeve or bushing, and a supplemental bufier spring surrounding the drawbar and bearing at its rear, end against said abutment and at its front end against said sleeve or bushing, substantially as set forth.

Witness my hand this 14th dayof May, 1894.

CHARLES A. GOULD.
