JOHN WILEY, 21), or some READING, MASSACHUSETTS,

Letters Patent No. 52,911, dated March 12,1867.

IMPROVED UAR-STARTER All D BRAKE.

TO ALL WHOM IT MAY CONCERN Be it known that I, Tom; W ILEY, 2d, of South Reading, in the county of Middlesex, and State of Massaehusetts, have invented a new and improved Gsr Starter and-Brake; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art'to make and use-the surne, reference being had to the accompanying drawings, forming part of this specification.-

This invention relates to 12. new and improved brskeproechcnism for railroud cars, constructed and arranged in such a manner that the device, when applied or operated as a btnlc'e to retard the movement or fully stop the core; will retein or hold the power which accomplishes that result, and be capable of giving it out or applying it insuch a. manner as to start, or did in starting, the cars,

The object of the invention is to obtain every simple and efiicicnt device for the purpose, one which may be manipulated with the greatest facility, ond'c'opable of, being constructed and applied to a car at a very moderate expense. 1 In the accompanying dra.wings-- I 3 Figdre 1 is a. side view of at car truck, partly in section, having my invention applied to it.

Figure 2, a transverse vertical section of the same, taken in the line at 9:, fig, 1.

Similar letters of reference indicate corresponding parts.

A represents the truck-franks of-a railroad car, end B, the Wheels thereof. These parts may be of usual con-' struction, and, therefore, do not require a special description. On one of the axles G of the truck there is firmly keyed a wheel, 1), which is fitted and works within an oblong slot or opening, a, in-aslide, E, said slide being provided with a horizontal cylindricalprojection, I which passes through a cross-bar, c, of the truck, and has a spiral spring, F, uponit', the inner .end of the spring bearing against the cross-her c, and the outer end hearing against a pin, d, which passes through 6 near its outer end, (see fig. 1.) G is an upright Windlass at one end of the truck-frame A, the lower end of said Windlass being connected by n chain, e, with asliding-bnr, H, at the under side of the slide E, the rear end of H having the lower ends of two eccentrics I I attached to it, said eccentrics being titted on the ends of o friction-roller, a in the rear of the slide. These eccentrics are placed loosely on the wheel I), one at each side of the slide E, and are retained in position on the axle, or prevented from letersllfy sliding thereon by circular plates J, secured in position by pinsfpcssing through the axle, (see fig. 2.) Therollcr a bears against the under side of the slide E; und the ends of the slot or openinga in slide E'sre of semicircular form, corresponding to the diameter of the wheel 1). Kiss a foot-lever or treodle, having it friction-roller, f, insertedin its under side, which rests upon the upper surface of the slide E.

The operation is as follows: When it is'designed-to retard the rnotion of the car, or stop it entirely, the driver turns the Windlass G, and thereby draws the sliding-bar H and the lower ends of the eccentrics II forwerd,'which throw or press upward the slide Epsnd cause the lower edge of the opening a in'the slide to hearugainst the lower edgeof the wheel I) on'the axle; and said wheel will force the slide back, and compress the spring F, the resistance of which retards or stops the car. In sturtingthe ear, the brakeman releases the Windlass G, and at the same time presses down the foot-lever or treadle K, which cnuses the upper edge of the slot or opening a to bear upon the upper edge of the wheel D, and the slide Evwill, under/the action of the spring F, be drawn forwzird, and the wheel D and axle G rotated in the direction to start or assist in starting the cur. I would remark that a device of the kind described is applied to each axle of the truck, as street. or city cars, forwhichthe invention is chiefly designed, are not turned at; the end of their route, the team being changed from one'endto the other. I would further remark that, if the car is not fully stoppedby the coin- ,pression of the spring F, a greet deal of friction is created by the contact of the forward semicircular ended" the slot or opening a with the wheel D.

I claim as new, and desire 'to'secure by Letters Patent- The slide E, provided with the oblong opening a, and cylindrical projection Z2, working through the cross bar 0, spring F, wheel I), upon the axle C, treadle K, eccentrics I I, sliding-bar H,'chcin e, and Windlass G,

when all ere constructed and arranged to operate as herein set forth, for the purpose specified.
