GUSTAVOS H EIDEL, OF ST. LOUIS, MISSOURI.

CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 275,650, dated April 10, 1883. Application filed January 25, 1883. (No model.)

To all whom it may concern:

Be it known that I, GUSTAVOS HEIDEL, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement' in Street-Gar Brakes, of which the following is a full, clear, and exact description, reference .being had to the accompanying drawings, forming part of this specification, and in which Figure 1 is a bottom view of a car, showing my improvement applied. Fig. 2 is part in elevation and part in longitudinal section of the lower part of a car. Figs. 3, 4,5, 6, 7, and 8 are enlarged views of different parts of the brake. Figs. 9 and 10 illustrate how the brake can be used when the brake-shoes are located on the inside of the wheels.

My invention relates to street-car brakes intended to be operated by foot-power; and my invention consists in certain features of novelty hereinafter fully described, and pointout in the claims. v

. Referring to the drawings, Arepresents the body of a street-car; B, the axles; G, the

wheels, and D the. brake-beams, with shoes D, as usual. The beams are connected by means of rods E to the lower ends of links F, depending from a hanger or bracket, G, secured to the bottom of the car, to which they are pivoted by pins G. To the lower ends of the links are pivoted short arms H, whose ends are secured together, and to the inner arms, I, of a double U-shaped' frame, I, by a pin or pintle, J. The frame I, when secured in place, is inverted, and between its inner arms, I, and outer arms, 1 fit the inner and free ends of levers K, (see Figs. 3 and 6,) which are pivoted to the bottom of the car by fulcrumbrackets L, and whose outer ends extend to the ends of the car, respectively, (see Figs. 1 and 2,),where they have pivoted to them arms M, that extend up through openings in the bottom of the car, and have secured to theirv upper ends foot-pieces N. It will now be seen that when the outer end of either one of the lovers K is forced downward, and its inner end thus raised, the frame I will be raised, drawing the lower ends of the arms or links F, and consequently the pull-rods E, toward each other, (see Fig. 4, their natural position being shown in Fig. 5,) thus applying the brakes. When one lever is operated it has no effect on the other, as will be plainly observed. When the outer ends of the levers are released they are thrown up by springs O, secured to the bottom of the car. When the levers are pressed down they may be held in that position by catches M,on the outer faces of the arms M engaging with teeth of bars P, secured to the ends of the car. (See Figs. 2, 7, and 8.) The foot-pieces N are pivoted to the arms or blocks M, and are capable of being thrown into avertical position, (see Fig. 8,) the object being this, that when the team is changed from one end of a car to the other the driver first throws the foot-piece of this end of the car up into this vertical position, so that any one standing on the platform cannot accidentally or intentionally apply the brakes by stepping on the foot-piece, nor can they by stepping on the upper end of the arm, for the lower end of the foot-piece-that is to say, the outer end of the foot-piece when it is in its natural position-will come against the bottom of the car, preventing the arm from being pressed down far enough to apply the brakes.

If the brake-beams were on the inside of forced apart, instead of being pulled together, to apply the brakes, and my brake can thus be used as shown in Figs. 9 and 10, Fig. 9 showing the natural position of the parts,and Fig. 10 the position when the brakes are ap plied.

I claim as my invention- 1. In a car-brake, the combination of hanger G, links F, pivoted to the hanger, arms H, pivoted to the links, frame I, to which the links are pivoted, and lever or levers K, pivoted to the bottom of the car, engaging with the frame I, and provided with a suitable foot-piece, all

the wheels they would of course have to be substantially as shown and described, the

3. In a car-brake, the foot-pieces N, pivoted the hanger or bracket, arms connecting the to to the arms M of the levers Kin such a manframe to the lower ends of the links, and ner that they can be turned up vertically, for brake-beams connected with the lower ends of the purpose set forth. the links, as set forth.

4. In a car-brake the combination of alever pivoted to the bott nn of the car, having a foot GUSTAVOS HEIDEL' piece at its free end, a frame operated by the Witnesses: lever, a suitable hanger or bracket secured to GEO. H. KNIGHT, the bottom of the car, links depending from i ALBERT G. FISH
