IMPROVED RAILWAY-TRACK SGRAPBR.

TO ALL WHOM IT MAY CONCERN:

Be it known that I SAMUEL A. OTIS, of Boston, in the county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Track-Scrapers; and I do hereby declare that the following is afull and exact description thereof, reference being had to the accompanying drawings,- and to the letters of reference marked thereon.

To enable others skilled in the art to make and use my invention, I will proceed to-describe its nature, construction, and use.

The nature of myinvention consists, first, in arranging the two shoes of a scraper and the connecting parts in such a manner that the shoesmay automatically adjust themselves to the varying gauge of the track; second, in combining with the shoe :1 small roller, which allows the shoe to run very nearly but not quite in contact with the rail; third, combining with the scraper a peculiar device, so arranged that the scraper inay be raised from or lowered to the track by a lever, which may be operated by the foot or hand. i

I Drawings.

Figure I is a side elevation of a part of a car, showing my improved track-scraper attached.

Figure 2-is a plan of the same.-

Figure 3 is an end elevation of the same.

In all the drawings, B 13 represent the shoes or scraper, shaped as shown inthe drawings, each being provided with a small truck-wheel, K, which serves to keep the shoe slightly elevated above the track, and consequently to save the wear of theshoe.

M, figs. 2 and 3, isa rod, passing freely through the shoes, having a head or screw-nut on each end, one of which is shown in fig. 1 by P. Q Q are sleeves, sliding freely upon the rod M, one end of eaehbearing against the shoe, and the opposite end against the forked soring O 0. By the above arrangement of the rod M, sleeves Q, and spring 0, it will be seen that the shoes BB maybe made to approach each other, and thus accommodate themselves to a narrow gauge, the length of the .rod M beingsuch as to admit of the shoes B B fitting upon the widest gauge likely to occur on ordinary roads."

To admit 0f the above-described action, the supporting-arms C C of the shoes are made-flexible.

R R are housings, upon which the arms 0 G'are hinged. L is a lever, attached to the bar C. E is a link, attached to the lever L, and to the armF of the rocker-shaft D, so if the said rocker-Shaft is operated, as it may be, by the lever G, the end of the lever L will be raised or lowered, carrying with it the arm 0 G and shoes 1313. G G are two arms, extending from the lever G, which serve as levers to be acted upon by pressure of the foot; thus, in fig. 3, by pressing hard upon the arm G, it will be pushed over towards T, which action would. raise the, arm F, and, through it, the link E the lever L, and thus the shoes B B. If the foot be placed upon the arm G, fig. 3, the shoes 13 B will be borne hard down upon the track.

T, fig. 3, is a circular plate, having a number of perforations, as shown, into which the pin, not shown ir. the drawings, attached to the handle H, may enter, and thus hold the lever (Land consequently the shoes 13 B, in any desired position. i

What I claim as my'invention, and desire to secure by Letters Patent, is

1. The combination and arrangement of the shoes'B B, sleeves Q Q, rod M, and fork O O, substantially as described and for the purpose set forth.

2. The combination, with the lever G, in a trackscraping machine, of the foot-lever G G, substantially as described and for the purpose set forth.

3. The combination and arrangement of the leverL, the link E, and the rocker-shaftl), made substantially as described and for the, purpose set forth.
