CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 392,829, dated November 13, 18823.

Application filed February 1B, 1888. Serin-l No. 264,443. (No model.) Patented in Canada March 2, 1838, No. 28,607.

To all wwm it 11mg/ concern:

Be it known that we, JOHN WILLMM SHOT- rrON and THoMAs HAwKrNs BARNES, both of the city of Montreal, in the district of Montreal and Province of Quebec, Canada, have jointly invented certain new and useful Improvements in Car-Brakes, (for which we have obtained Letters Patent of the Dominion of Canada, No. 28,607, granted March 2, 1888,) and we do hereby declare that the following is a full, clear, and exact description of the saine.

Our invention has reference specially to brakes used on freight-cars, its object being, without interfering with the present system by which brakes are applied to single pars bythe brakemen, to provide means by which the.

locomotive-driver can put on all the brakes in the train, or, in other words,to furnish freighttraius with a continuous brake system, which may be operated from the calo of the locomotive. It may be thus briefly described: We propose to arrange under each car a rod, carried in suitable hangers and provided at both ends with hooks or other means of attachment to the rod under the next ear,the whole length of each rod, including the connecting device, being just so much longer than the car itself and the draw-bars as will allow of the rods being coupled together. Under the tender of the locomotive will be arranged a similar rod connected with the piston of asteam-cylinder set longitudinally under the foot-plate and provided with inlet-pipes by which the steam can be taken into it from any part of the boiler and proper discharge-pipe.

The mechanism by which the traction ofthe rods in either direction will operate the brakes is as follows: To the end of the long arm of the brake-lever is attached a link connected by a chain with any part of the rod on the other side of the center ofthe truclnso that the draft on the rod in that direction will opcratein exactly the same way as the winding up of the r chain by the brakeman.

From the end of the above link, connected with the brake-lever, is taken another chain, which, passing around a roller secured to the truck-beam or car-frame, is returned and aterence must be had to the annexed drawings,

forming part of this specication, in which- Figure lis a view ofthe under side of part of a locomotive with tender and a car fitted up with our brake apparatus; Fig. 2, a similar view,cnlarged,of a single car; and Fig. 3,a side view of same, partly broken away.

Similar letters of reference indicate like parts.

As the brake mechanism itself' is in no way altered from that now in use, and is clearly shown in the drawings, no further reference will be made to it.

A A are the rods carried centrally in suitable bearings, respectively, under the tender and the car and connected by hooks and links B B.

a a c a are respectively eyes formed in the rods to allow them to pass the king-bolts of the car-trucks.

C is in each car a link connected at one end to the end of the long arm of the brake-lever and at the other by a chain or series of links, D,to the rod A at a point, d, the otherside of the truck-beam.

E is a chain,also connected to the end ofthe link C,passing round a roller, sheave,or pulley, F, secured on the truck-beam or to the carframe and having its other end returned and attached to the rod at a point, c, on the same side of the truck-beam, the points d ande being about equidistant from the center of the truck.

G is a steam-cylinder placed,preferably,un der the foot-plate of the locomotive longitudinally in the line ef the rods,and provided with proper inlet and outlet pipes, g y, for the admission and discharge of steam and means for regulating same.

H is the piston-rod of the cylinder G, connected with the rod under the tender.

IDl

lt will be seen that when the rods under the cars are coupled together the driver can, simply by letting steam into the cylinder behind the piston, draw on the whole line of rods and put the brakes at once ou all thecars, it being indifferent which end ofthe car is in front.

Our invention will dispense, except in Very rare cases, with the necessity of the brakemen running along the roof to put on the brakes, and may enable the train to be worked with fewer hands.

Vhat we elaiin is as follows:

l. In combination with a freight or other car, a rod secured longitudinally underneath the ear with coupling,` devices at both ends, a link secured to the end of the long arm of the brake-lever and attached to the rod by two chains, one taken directly to the rod at a point on the far side of the truck beam l'romthe brake lever and the other taken round asheave or pulley returned and attached to thefrod at a point near the brake-lever, the whole operatingas herein described,to put on the brakes when the rod is drawn upon in either direction.

2. In combination, freightears provided with rods hu ng underneath them,linkssecured to long arm ol' brake-lever and attached to rod atpoints on either side oftruekbearn by chains, one taken direct and the other returned round a sheave,said rods bei ng coupled togetherand to a similar rod under tender,and a steam-cylinder underlocomotivc with its piston-rod connected with rod under tender, all as herein set l'orth, and for the purposes described.
