J. B. VAN, Bran-or NASHVILLE, TENNESSEE.

Letters Patent No. 97,7 30, dated December 7, 1869; an-tedated November 30, 1869 IMPROVED RAILWAY-OAR BRAKE.

The Schedule referred. to in these Letters'Patent and making part of the sa'me.

'Be it known that I, J. B. Van Drxmof Nashville, in the-county of Davidson, and State of Tennes- Figure2, a similar section of another car with my train, would be placed in the rear of the car shown in fig. 1.

The object of my invention is to provide an improved method of operating railroad-car brakes, by

I means of which all the brakes of a train can be simulw taneonsly applied and released, or the-brakes of each car operated sepa 'ately, as desired; to which end,

My improvements consist in a vertically-mo able block, containing three sheaves or grooved pulleys, and

placed in a frame beneath the centre of a railroad-car,

1 the same being connected, by a rope or chain passing over its lowest pulley, and underguide-pulleys on the frame, to, brake-beams on each side of the truck- J-wheels, and likewise connected, by ropes; or chains passing under its upper and centre pulleys, respectively, and over guidepulleys in the frame, to brakei shaft-s on the car, and to the/shaft of a tiller-wheel,

, placed on the forward car of the train, in such manner, that when the block is raised or lowered by either of theropes last stated, the brakeswill he applied or released, andfthis operation perfin'med upon one or i more cars independently of each other, or all the cars of a train simultaneously, at pleasure, as hereinafter more fully set forth. i By my improvements, the brake-shoes are applied toboth sides. of the truok-wheelsaml the pulley is substituted for the lever in the "application of the power, thereby removing the objections which have heretofore prevailed against the application of all the brakes of a train simultaneously, it having been found that, ordinarily, the brakes of the rear cars will not free themselves, and the jar and rattle of the levers beneath thecars are a' constant source of annoyance to travellers.

In the accompanying drawing, which shows a convenient arrangement of parts for-carrying out the object of my invention- ,A I'epresents the car on which the tiller-wheel, for

operating the brakes of the entire train, is ,pla ced, and

which, for passenger-trains, would be the baggage-car,

as being the forward car. i

B represents any other car of the train. I A movable block, E, containing three sheaves o I nary construction.

grooved pulleys, a e 0 is placed in a frame, D, beneath the centre of the car.

A wire rope or chain, F, passes under the upper pulley e, and over fixed guide-pulleys d, on the frame I), being secured, at its ends, to brakesl1afts F, provided with hand-wheels or cranks f, and located at the ends ofthe car. I i

By rotatingthe brake-shafts, the block E will be raised or lowered, according to the direction in which they are turned. g Y

A tiller-wheel, G is mounted upon a horizontal shaft, G, in the baggage-car or forward car of the 'train.

'A rope or chain, G, is secured to the shaft G and passes under a guide-pulley, g, on the frame D thence over another guide-pulley, (I, under the second pulley e, of the block E, and over a third guide-pulley, d. Thence it is continued to the next car, and passes over guide-pulleys d d, and under the central pulley a of the block E of that car, in' a similar manner, and so on through the whole train, 'its end being secured to the rear of the last car. V I

It will be readily seen, that by suitable rotation of the tiller-wheel G", which is provided with a pawl, g",

and ratchet y, to prevent it from turning backward until it is desired to release the brakes, the blocks E y of all the cars in the train can be simultaneouslyraised or lowered.

A rope or chain, H, passes over thc'lowcst pulley e of the-block E, and under guide-pulleys (l on the frame D, Extending thence toward the end of the car, it passes around pulleys J upon movable rods J, beneath the trucks 0, which pulleys reverse its direction; thencearound pulleys i, on'the outer brakebeams I, toward the centre ofthe car, by which its direction is again reversed, and is finally secured at each end of the inner brake-beams 1 of the truckwheels which are nearest the centre of the car.

Chains or ropes J are attached to the opposite ends l of the rods J, and, passing around pulleys t, on the outer brake-beams of the truck-wheels nearest the ends of the car, are secured to the inner brake-beams of the same.

The brake-beams are hung to the truck-frames by links or straps i and carry brake-shoes 'i' of the ordi- From this arrangement, it will be observed, that when the blocks E are raised by either of the ropes F G, the rope H and its connections J J 1 will apply the brake-shoes toeach side of every wheel of the ear.-

'By the application of hand or other power to the tilleiwwheel G", the blocks E of all; the cars will be Simultaneously raised, by means ofthe rope or chain G, thu'senabling the brakes to be applied to the whole train without loss of time, and causing thespeed of the same to be rapidly checked, thus afiording protection against collisions and runs off, and the loss of life and damage occasioned thereby.

In case of breakage of the rope G, the brakes can be applied independently by means of ropes F; or the latter method may be employed, if desired, without interfering with the proper working-position of the rope G, which rope, it should be stated, may be either in one piece for the entire train, or in separate sections on each ear, united by proper connections.

Having thus fully described my invention,

What I claim therein as new, and desire to secure by Letters Patent, is-

1. The tiller-wheel G, in combination with the rope or chain G, guide-pulleys g d d, and movable blocks E, the whole constructed and operating substantially as described, for the purpose of simultaneously applying and releasing the brakes of a railroad-train, as set forth.

2. The brake-shafts F and ropes or chains F, in combination with the guide-pulleys d, blocks E, and pulleys ee, substantially as described, and for the purpose of operating the ,brakes of each car separately, as set forth.

3. The rope or chain H, rods J ,'and ropes or chains J in combination with the pulley e, guide-pulleys d, pulleys J i t", and brake-beams I I, the whole constructed and operating substantially as described, for the purpose of applying the brakes to both sides of the. truck-wheels, as set forth.

In testimony that I claim the foregoing invention, I have hereunto set my hand, this 12th day of December, 1868. I
