$lI-EOIFICATION forming part of LettersPatent No. 289,474, dated December 4, 1883.
Application filed April 12, 1883. (No model.)
To all whom it may concern.-
Be it known that we, EVAN VVIE and JOHN TAYLOR, of Troy, in the State of New York, have invented certain new and useful Improvements in Gar-Brakes, and we do hereby declare that the'following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification, in which Figure l is a longitudinal section taken through the bed of a car broken into sections, for the purpose of illustrating our improved system of brakes; Fig. 2 is a plan view of Fig. 1. Fig. 3 is a side view of the center chain-wheelhaving its spurred gearing. Fig. 4 is a view looking at the lever D either forward or backward. Figs. 5 and 6 are modifica-tions of our invention. a
This invention relates to car-brakes wherein a cylinder having a piston in it is used, the latter being actuated by air, controlled by the engineer or by any person located on a coach composing one or moreofthe make up, as
will be fully understood from the followingdescription,when taken in connection with the annexed drawings.
A designates the bed of a railroad-cannuderneath of which are trucks constructed in the well-known manner.
B designates an angular arm, which weattach to the piston-rod of the well-known airbrakeoylinder B, adapted for air car-brakes. This rod is applicable to the piston-rod of the Westinghouse air-brake cylinder, and the angle a of the arm which eXtendsinwa-rdly is perforated to receive a rod lettered 1, which passes through it freely, which rod is connected to the hand-brake shaft 2, a chain being interposed. The rodl has a collar, a, fixed to it, either by welding or pinning, so that when the brake is not in immediate use the said collar is in closelcontact with the said angular arm, as indicated, in Fig. 2. When the air pressure is caused to bear against the piston in the cylinder B, the brake is at once in action on both trucks. Vhen the piston in the saidcylinder is not acted on by air, manual power can be applied to hand-brake rod 2,
and rod 1 will slip through the hole onthe angular arm B.
is a toothed lever, the'segment of which meshes with the spur-wheel (J, on the under side of which is a grooved chain-pulley arranged under the longitudinal center of the car-body, and equidistant laterally from its side sills. When the lever Btis moved, it turns the toothed wheel and its chain-pulley and winds the chain attached to the rods 3 and 4., and applies power to the arms of levers Du These levers are located on and-have their fulcra on the truck-frames, as shown in Fig. 2, and the ends of the levers are bifurcated, as
shown in Fig. 4, and have chain-wheels 1) applied to them.
E is a nutscrewed to an eyebolt which passes through the brake-beam of each truck, and is used to lengthen or shorten the brakerods J, for the purpose of taking up or shortening the slack and compensating for the wear of the brake-shoes, and also for the expan sion and contraction of the rods.
For the purpose of illustrating what we have abovedescribed, and shown iirtliedrawings hereto annexed, we will state that in case rod 1 should break it will not disablethe air-engine, or if a break should occur between arm B and the brake-shoes the hand-lever at the opposite end of the car can be operated successfully to brake the train or the car. Now, if rod 2 breaks it would not interfere with the air-engine,-and if rod 3 should break power can be applied so as to brake on the opposite truck; and, again, should rod 4 break the same result would necessarily obtain. In short, if any of the rods leading from the lever D to thebrake-beams should give away it is obvious that the result would be that only the brake beams-on the trucks to which the broken rod is applied, would be disabled.
It is obvious also that by our improved system power is applied almost directlyto the brakes, and that this is done through the mefrom which chains and rods act through the 'medium ofthe said levers D and their connecting-rods; also, that if the brakes are properly set for close action, and the power in the hands of the engineer is fully applied, every wheel throughout a train will be held so that it will not revolve; also, that when power is applied to'the air-cylinder every pound of pressure is immediately directed to the truck.
The rod of the piston in cylinder B may be dium of levers B acting on a central gearing,
extended beyond the arm a and passed through a guide or eyebolt, P, which depends from the bottom of the car, as shown in Figs. 5 and 6. By thus guiding the piston-rod lateral vibration or strain is prevented.
Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is I 1. The combination, with an air-cylinder applied to a railroad-car, of an angular pistonrod and a rod which is connected to a handbrake and also to a brake-lever, D, all constructed and adapted to operate substantially in the manner and for the purposes described.
2. The combination, with an angular pistonrod, of an air-engine, a rod, 1, a nut or shoulder applied on this rod, a hand-brake shaft, and a lever which engages by its segment with a central chain-wheel pinion connected to the brake-bars, all constructed and adapted to operate substantiallyin the manner and for the purposes described.
8. In a system for applying brakes to railroad-cars, the combination, with a single cylinder having a piston working therein, an angular piston-rod, a brake-rod applied to work freely through one end of said piston-rod, a shoulder on said brake-rod, and afiexible con nection with segmental levers which are in 30 gear with a central chain-pulley, all constructed and adapted to operate substantially in the manner and for the purposes described.
4. The combination of brake-bars hung from the truck, toothed levers B, actuated by an engine, B, the toothed wheel 0, with its chainpulley gearing with said levers, a rod and chain connecting the chain-pulleywith levers D, the chain-pulleys b, rods and chains J, eyebolts passed through the brake-bars, and nuts for adjusting said rods and chains, all constructed and adapted to operate substantially in the manner and for the purposes described.
5. The combination, with the brake-bars hung from the truck-frame, bifurcated lever D, arranged in a vertical plane, the chain-pulley between the prongs of the said lever, chains and rods connecting said pulley with the brake bars, a rod and chain connecting said lever with a chain-pulley, and the connections between this pulley and an air-engine, all constructed and adapted to operate substantially in the manner and for the purposes described.
In testimony that we claim the foregoing as our own we a'ffix our signatures in presence of two witnesses. 7
