I Improvement in Railway-Car Brakes.
No. 130,030. I I Patented July 30, 1872.

KARL EXTER, OF MUNICH, BAVARIA, ADMINISTRATOR OF KARL EXTER,
, SENIOR, DECEASED.
IMPROVEMENT IN RAILWAY CAR-BRAKES.
Specification forming part of Letters Patent No. 130,030, dated J uly 30, 1 872.
To all whom it may concern:
Be it known that the following is a full, clear, and exact description of an Improvement in Brake-Motions for Locomotive-Tenders, Railroad Cars or Wagons, and other Vehicles; the same being the invention of KARL EXTER, senior, deceased, late of Munich, in the Kin gdom of Bavaria, reference being had to the accompanying drawing forming part of this specification, and in which-- Figure 1 represents a sectional side elevation of a locomotive-tender in part, with the improved brake-motion applied thereto; and Fig. 2, a sectional end elevation thereof.
Similar letters of reference indicate corresponding parts in both figures.
The object of the invention is to reduce the labor of applying-the brakes; and the invention consists in a brake'motion which is controlled by a weight carried by a lever or swingingarm so set or arranged that when it is desired to apply the brakes it is only necessary to start the weight that controls them over the fulcrum or center of the lever which carries the weight, and whereby hand-power may be combined with the weight to regulate the controlling force of the latter on the brakes.
In the accompanying drawing, A represents the body of a locomotive-tender, and B B its wheels, to which the brakes or friction-blocks O O are applied, as through a cross-shaft, l), operated by a lever, E, and connected with the blocks by cross-arms b and links 0. The devices for raising and lowering the lever E,
i to put the brakes ,on and off the wheels, are
as follows: F is an upper independent horizontal shaft, made capable of vibration by a lever or handle, G, and carrying a further lever or arm,H, having either an adjustable or fixed weight, b, on it. Furthermore, this shaft F is provided with a crank, I, which is connected by a pitman, J, with the leverE. The weighted lever H and crank I are so set in relation with each other that when the one is up the other is down, and so that when the crank I is depressed to its fullest extent to relieve the brake-blocks C 0 from contact with the wheels the weight on the lever His made to occupy a position "over. the shaft F a little to what may be termed the off side of its center, and
said lever, when thus adjusted, made to rest against a suitable stop. Thus adjusted, as shown by full lines in Fig. 1, theweighted lever H holds the brake from off the wheels. When it is desired to apply the brakes it is only necessary to start the weighted lever H over its culminating line or center, and so that it will fall, as shown by dotted lines inFig. 1, said lever, in falling, turning the shaft F and elevating the crank I, which action throws the brake-blocks onto the wheels and transmits thereto the efi'ect of the weight b multiplied by leverage. By applying the hand to the lever G the pressure of the brakes on the wheels may be increased or diminished, as required. The pitman J is fitted to turn freely in the head that connects it with the crank l, and is provided at its lower end with a screwthread, which fits a nut in the lever'E, so that by turning said rod, as by a hand-wheel, d, to the right or to the left, the distance of the brake-blocks from the wheels can be adjusted so as to secure to said blocks a definite throw at all times, or, in other words, to provide against wear of the blocks, and so that when, by reason of the wear of the blocks, the weighted lever in operating falls below its proper level, the same can be raised or adjusted, as required. To throw off the brakes, the weighted lever H is lifted, by means of the. handle G, to its elevated or normal position What is here claimed, and desired to be secured by Letters Patent, is-
1. The combination, with the brake-operating lever E, of the weighted lever H and pitman connecting it therewith, the crank I, and the handle or lever G of the shaft F, when the whole are arranged in relation with each other, for operation of the brake-blocks (J G, substantially as specified.
2. The combination of the rotating pitman J, having a screw-thread on it, with the lever E, in which it is adjustable, the brake-blocks O O, the crank I, the shaft 13, and the weighted lever H, essentially as herein set forth.
