UNITED STATES PATENT OFFICE.
CAR-BRAKE.
SPECIFICATION forming part of Letters Application filed February 18, 1882.
To all whom it may concern Be it known that I, ARTHUR E. BEATTIE, of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Oar-Brakes,of which the following is a full, clear, and exact dcscription.
The object of myinveution is to facilitatethe working of car-brakes by utilizing the motion of the moving train. y
The invention consists in friction wheels mounted rigidly on an axle journaled in adjustable frames below the car, which frames can be adjusted by means ofa shaft, from which a lifting-chain passes to these frames, to which shaft other chains are attached, which pass over suitable pulleys acting on the brakechain, and are then attached to the axle of the friction wheels, whereby when the frictionwheels are lowered to be in contact with the car-axle or the rails the chains connected with the brake-chains will be wound'on the axle of the friction-wheels, thereby pressing the brakes against the wheels, and at the same time pressing the friction-wheels against the car-axle or the rails. When the frames in which the friction-wheels are journaled are raised the chains for applying the brakes are loosened.
The invention further consists in the combi-. nation of parts, as will be f ully described hereinafter.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure l is a longitudinal elevation of a car provided with my improved devices for working the brakes by utilizing the motion of the moving train. Fig. 2 is a cross-sectional elevation of the same. Fig. 3 is a diagram of the device, showing the friction-wheels adapted to engage with the car-axle.
Two friction-wheels, A, rigidly mounted on an axle, B, rest on the rails O or against the axle D of the car-wheels D. This axle B is jourualed in a series of frames, E, pivoted to the under side of the bottom of the car F. A chain or equivalent device, G, is attached to the lower end of one of these pivoted frames E, preferably to the middle one, which chain is also attached to a shaft, H,journaled in down- Patent No. 258,353, dated May 23, 1882. I
(No model.)
ward projections or lugs H on the bottom or may be attached to each end of the shaft H.'
The locksKaud racks L can be dispensed with, and the levers J of the several cars united by a chain or rope, so that all the brakes can be applied simultaneously from the locomotive or some other part of the train. A chain, M, or equivalentdevice, is attached to each drum 1, which chains pass over pulleys N, coupled to pulleysO, hanging from the brake-chains P,
these chains M passing from the pulleys N to the axle B of the friction-wheels A, to which axle B the chains M are attached. The brake. chains P are attached to the inner brakes, Q, pass over pulleys It on the outer brakes, R, and over pulleys S, suspended from the bottom of the car, and over the above-mentioned pulleys O, suspended from the brake-chains P. Only one brake-chain P and only one chain M and pulley I may be used; but I prefer the construction shown. 1f the friction on the caraxle is used to apply the brakes, but one friction-wheel A will be required.
The operation is as follows: The train moves in the direction of the arrow a. If the brakes are to be applied, the lever J is moved in the direction of the arrow 1) until it is in a vertical position, (shown in Fig. 1,) whereby the chain G will be unwound from the axle H and the frames E will descend until the wheels A rest on the rails. The levers J are locked in this position. Either all the levers Jaare moved simultaneously or each sin gly.- The friction of the wheels A on the rails will cause a rotation of the wheels A and the axle B in the direction of the arrow (1, whereby the chains M will be wound on the axle B. The drums I are fixed and cannot rotate, and consequently the tension of the chains M will be increased, and as this tensionincreases thepressureofthe wheels A on the rails increases correspondingly, as this tension of the chain M draws the lower ends of the frames E in the direction of the arrow-a", thereby pressing thewheels A more firmly on the rails. The greater friction of the wheels A on the rails in turn causes a 5 greater tension of the chain M, and this causes a movement of the pulleys N O in the direction of the arrow 9. This movement of 'the pulleys N 0 causes strains in the brake-chains P, as indicated by the arrows h, whereby the 1:0 brakes will be pressed against the wheels. If the brakes are to be loosened, the levers J are unlocked and moved in the inverse direction of the arrow 1), whereby the chain G will be wound on the shaft H and the frames E, I 5 and the wheels A will be raised from the rails, andthe' chains M will be unwound from the *p'ull'eys I 'and slackened, thereby causing the brake-chains 'P to be slackened. As long as the levers J are not locked the brakes cannot zd be applied,*for' assoo'nas the wheels A come in bon'tact with the rails the tension of the chain M-will rotate'the drums I in such amanner that' th'e'chain G will be wound on the shaft 'Hjwherebythe frames E and the wheels A will 25*be raised immediately. However, when the b'r akes are not to be applied the levers J are "locked-in 'such a position that thechains G "will-keep the framesE and the wheels A raised, *so 'thatthe wheels cannot come iu'eontact' with 3dthe rails. If the wheels are arranged to come in con'tac'twith the axle D instead of with the 'rails,theoperation will be the same.
"Having thus fully described "my invention, I claim as newa'nd desire to secure by Letters 3 5 Patentwheels A, mounted rigidly on an axle, B, jour naled in adjustable frames E, the chains M, attached to the axle B and a shaft, H, the pulley S on the bottom of the car, the coupled pulleys N O, and the brake-chains P,-substantially as herein shown and described, and for the purpose setforth.
8. In a device for applying car-brakes, the combination, with the brakes, of the frictionwheels A, mounted rigidly onan axle', B,'jour* naled in adjustable frames E, theliftiug-chain Gr, attached to the frames E and to a shaft, H, the chain M, attached to theaxle Band to pulleys or drums I on the shaft H, the lever J, for turning the shaft H,'andderices for looking this lever J in the desired "position, substantia-lly as herein shown and described, and
"for the purpose set forth.
