JOHN SHELTON, OF DENVER, COLORADO.

CAR-BRAKE MECHANISM.

SPECIFICATION forming part Of Letters Patent No. 758,391, dated April 26, 1904;

Application filed July 31, 1908. Serial No. 167,774. (No model.) i

To all whont it may concern:

Be itknown that I, Jornv SHELToN, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Oar-Brake Mechanism; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings,

and to the figures of reference marked thereon,

' accompanying drawings, with which is illusthe wheel-axles.

trated an embodiment thereof.

In the drawings, Figure is an underneath v1ew of a car equipped with my improved beamless' brake mechanism. Fig. 2 is a side Fig. 3 is an end view elevation of the same. of a car equipped with the mechanism, the wheels being partly broken away to disclose the shoes or brake-heads, which are inside connected or located between the wheels. Fig. 4: is a perspective view in detail, showing a brake-shoe and the lever connected therewith. Fig. 5 is a plan view illustrating the brake-shoes and lever connections.

The same reference characters indicate the same parts in all the views.

Let the numeral 5designate the brake shoes or heads, with which are pivotally connected the live-levers 6 and the dead-levers 7. These levers all occupy a horizontal position below Each pair of levers, composed of one live-lever and one dead-lever on each side of each truck, is connected by a rod 8, located inside the vertical plane of the wheels. The extremities of each rod 8 are pivotally connected with the

levers

6 and 7 of wardly from the car-Wheels. The inner extremity of lever '7'is pivotally connected with a depending bracket 9, "suitably' connected at its upper extremity with the 'bolster'of the car-truck. This bracket is provided with a number of openings whereby the position of whose opposite extremity is pivotally connected with the lower extremity of an inclined lever 13, whose upper extremity is pivotally connected with the car-body, as shown at 1&.

" Pivotally connected with the central part of each lever 13 is atop rod 15, which is actuated from the brake-cylinder 16 through the medium of any suitable connections.

I desire to call especial attention to the fact that the dead-levers 7 are at the inner ends of each truck and are used to press the brake-- .55 the lever may be adjusted or regulated as By this means the live-levers 6 are operated with a straight horizontal pull.

i From the foregoing description it will be I understood that as the brake-rod 15 is actuated the inclined lever 13 is operated, whereby power is applied to the

levers

6 and 7, with the result that the brake-heads are forced toward the wheels and the shoes applied thereto with the necessary pressure for brake-setting purposes. The brake mechanism may be operated by hand through the instrumentality of the ordinary brake-wheel 17, mounted on a shaft 18, journaled in the car and suitably connected with the brake-setting devices. By reason of my improved mechanism it may be observed that the movement of the brakeshoes is such as to prevent'them from slipping oil the treads of the wheels, since the tendency is rather to move them toward the wheel-flanges.

Having thus described my invention, What -I claim is 1. In a car-brake mechanism, the combination with the brake-heads, of horizontal deadlevers at the inner end of the truck, horizontal live-levers at the outer end of the truck, said levers being connected to the brake-heads, a rod connecting each pair of levers composed of one live-lever and one dead-lever on each side of the car, and a rod connected to the inner ends of the live-levers and passing toward the center of the car between the fixed ends of the dead-levers; and an inclined lever connected at its upper end to the body of the car, and at its lower end to said rod, and a brake-rod connected to the inclined lever intermediate of its extremities, substantially as specified.

2. In car-brake mechanism the combination with the brake-heads, of horizontal live and dead levers connected with the brakeheads and extending inwardly transversely toward the center of the car, a rod connecting each pair of levers composed of one live-lever and one dead-lever on each side of the car, a yoke connected with the inner extremities of the live-levers of each truck, a rod connected with the yoke, an inclined lever connected with the said rod remote from the yoke, and a brake-rod connected with the inclined lever.

3. In a car-brake mechanism, the combination with the brake-heads, of horizontal deadlevers at the inner end of the truck, horizontal live-levers at the outer end of the truck; rods connecting the central portions of each pair of levers composed of one live-lever and one'dead-lever on each side of the car; ayoke connected with the inner extremities of the live-levers; a rod connected to the yoke and extending toward the center of the car between the fixed ends of the dead-levers; and an inclined lever connected at its upper end to the body of the car, and at its lower end to said rod, and a brake-rod connected to the inclined lever intermediate of its extremities; substantially as specified.

4. In car brake mechanism, the combination with the brake-heads, of horizontallydisposed live and dead levers connected with the brake-heads and extending transversely toward the center of the car, a rod connecting said levers, a depending bracket with which the inner extremity of each dead-lever is connected, a yoke connecting the inner extremities of the live-levers of each truck, a longitudinal rod connected with the yoke, an inclined lever whose lower extremity is connected with the said rod remote from the yoke, the upper extremity of said rod being connected with the body-of the car, and a brakerod connected with the inclined lever intermediate its extremities.

In testimony whereof I afiix my signature in presence of two witnesses.
