IMPROVED GAR-BRAKE.

TO ALL WHOM IT MAY CONGERN:
Be' it known that LLYMAN CLAIK, of Pine Island, inthe county of Goodhue, and State of Minnesota, have invented n new und useful Improvement in Car-Brakes; and I do hereby declare that the following-is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference bein-g had to the accompanying drawings, forming a. part of this specification.
The object of this invention is to furnish a brake for stopping ears on railroads, and the invention consists in operating friction-wheels or rollsin contact with the truck-wheels ofthe car in such a manner that the brakes may be thereby applied at one and the same time to a train of cars orto a single car, as may be desired, and in the manner hereinafter' described. y
Figure 1 represents vo, vertical longtudinal'section of a train of two railroad-ears with my brake attached, the section being through the line :u a: of tig. 2.
' Figure 2 is a top or plan view ofthe same.
Similar letters of reference indicate corresponding parts.
A represents the truck-wheels of the railroad-curs.
B, thev framework of the truck.
C represents the friction-wheels or rolls which I apply to the truck-wheels, by which the brakes are operated.
D represents the brakes. l A
The brake-bars D are att'ached to'the frame of the truck by straps of iron, being near to the pcriphcries ofthe wheel when not in actual use. The brakes o r friction-shoes D, which are brought in contact with the truck-wheels when in use, arc attached to the ends of the brake-bars D.
F represents the shafts of the friction-rolls C. Y
G represents ropes or chains which pass through orare attached to the shafts F, the ends of which ropes or chains are attached to the brake-bars D', as scon'in the drawing. K
The friction-rolls are attached by their shafts F to frames marked 1I, in the drawing, on which frames the said shafts have their bearings, and by which they are supported and Controlled. A v
It will b e seen that when the friction-rolls C are lowered or brought in contact with the revolving truckwheels', the shafts l", to which the rolls are attached, will be rotated, which will wind up the rope or chain around the shaft E, as seen in the drawing, and consequently draw the brakes toward and in contact with the cur-wheels, thereby creating friction sullicieut to stop the cars. A
On the brake-bars D there are placed elliptic springs c2', with which the 'ropes or chains are connected, the tension of which serves to take olf the sudden tension or strain on the brake-chains when the brakes are applied while theA train is under a high rate of speed.
The frames H are attached to the truck nt one end by a joint, as seen at a. Atthe other end thcyare connectedby a rope or chain,f, with a shaft marked J, which passes through or is supported by the'framcwork of every car, as seen in the drawing.l l
By revolving this shaft theehainfwill be wound around it and the frame H, and roll G raised thereby. For the purpose of braking or stopping all the cars in a train simultaneously, these shafts J are connected l together by universal joints K, so that the engineer or other person may apply the brakes when necessary, and
the arrangement is such that the brakes may bs applied to all the cars in the train frein any ope of the cars, for each car is providediwithn hand-wheel and shaft, with a worm-screw, which engages with n pinion on the` 'shaft J.
This arrangement is secu in fig. 1.
L is the hand-wheel.
M is the-vertical shaft.
N is the worm-wheel on the shaft.
l is the pinion.
The universal joint K allows of the lateral and verticalor irregular upand-down motion inseparable from railroad-cars.
The shaft m is supported from the platform or by the truck-frame, and the arrangement does not differ materially from that in common -use as regards position and the manner in whichit is supported.
To provide for the irregular longitudinal motion of the cars back and forth, which invariably occurs in ltrains, I form an extension-joint in the shaft J', which is marked o, which enables the cars to approach towards or recede from each other any distance which is allowed by the car-coupling or coupling-link.
This extension-joint is formed oftwo rodspp, fig. l, and a rod, p'. g
r is a head-bar, which is rigidly attached to the rod p', and which slides on the rods.
s is 'another head-bar, to which the rods are attached at one end, and through which the rod p slides.
The other ends ofthe rodspp are rigidly attached to the universal joint K, as seen in the drawing.
It will be seen that, should the cars (lig. 1) approach each other, the rod marked p will slide through the head-piece s, and that the head-piece r will slide on the rods p p, thus allowing of longitudinal motion, and at the same time allowing a rotary Yinotion to the shaft J.
The upright shaft m isrotated by the hand-wheel L, and the worin-wheel is thrown out of gear with the pinion Zon the shaft J by a shifter (not seen in the drawing) when the brakes are to be applied.
This is for the purpose of applying the brakes in less time than it can be done by reversing the worm-wheel.
Having thus fully described my invention, I claim therein as new, and desire to secure by Letters Patent- The friction-wheels or rolls C and shaft F, combined with the wheels of a railroad-car, und with the brakes controlling the same, when operated by a chain or cord winding upon a, horizontal rod or shaft beneath the car, substantially in the manner and for the purpose hereinvset forth.
The aboire specification of my invention signed by me, this 20th day of June, 1867.
LYMN CLARK.
