NEW YORK, AssIGNoR To HIM- Letters Patent N 94,083, detail August 24, 1869.

IMPROVED RAILWAY-CAR BRAKE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom fit may concern:

Be it known that I, JAY M. CnosnY, of the. town of Marathon, in the county of Cortland, and State of New York, have invented a new and useful 1mprove. ment in Car-Brake and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming a part of this specification, in which- Figure l is a plan view of my invention, placed on the bare trucks to' show its construction.

Figure 2 is a side view of the same, with thel near half of the ear cut away, the hotter to show my plan.

y Figure 3 is a view of thatpart ot" my invention by 4wiiehthe same is shifted, and adiusted for moving in opposite directions. f

Figure 4 is the end view of the car-bumpers.

Figures 5 and 6 are Vrespectively side and end views of the block used iu connection with my invention, and as a part thereof.

Similar letters of reference indicate like parts.

ln the accompanying drawings- A is a car-wheel.

b is the axle thereof.

(l, the usual wooden bar, which is attached to and holds the brake-blocks d.

E is the bumper, in common and general use.

f is the inner headof the new bumper.

y g are the rods thereto, extending to the end of the car, and uniting with the false-or new bumpers V.

7l are two elastic iron or steel b'ars or rods, forming springs, and connecting the inside heads f j, of new or i'alse'bmnpers, with the centre lever t'.

j is an arm, used, by means of the chains or cords t 'fand s, in connect-ion with the usual brake-wheel and ratchet u and r, to shift the brakes for use in different directions. Y j

l.: is a lever, which, by being firmly attac-hed to the post x, with the lever 1'. and arm j, is made, by mea-ns of power applied to said lever and arm, as hereinafter explained, to operate the bars C, and apply the brakeblocks fl.

Z is a lever, working upon the pivot 71'.

m is a lever, working upon the point G'.

n is a lever, working 4nponithe point o.

o is a lever, working uponthe point d.

p1) are rods or cha-ins, ot' iron, connecting the lever la with long arms of the levers n and o. n

p' p are rods or'chains, of iron, connecting said lever L with the long arms of levers Z and my..

q q are rods or chains, of unequal length, which, with the car' going in the direction of the arrow in i gs. 1 and 2, connect back-bars C C of the re'ar truck with the shoit arm of the lever I.

q' q aresimilar rodsor cha-ins, connecting the backbars C C of the forward truck with the short arm of the lever o.

lr 'r are similar rods or chains, connecting the forward bars C C ofthe rear truck with the sh'ort arm of the leverI v -r' r are similar rods or chains, connecting the forward bars G C of the forward truck with Ythe short arm of the lever n1.

z s are coil-springs, so placed and constructed around the bars or rods r/ g as to throw the same back to position after being u`sed.

Fig. l rcpresentsthc car as moving in the direction of the arrow, or to the right.

It will be seen that the arm j is thrown forward by means of the brake-wheelc, and held in that position by means of the ratchet on said wheel, as therein shown, it being attached by means of the. chain t.

The heads ot thenew erffalse bumpers, extending beyond the bumper by which the ears are coupled, strike eac-h other when the engine is slowed, as shown in fig. at 4YV, thus' pressing the forward end of the lever Ai backward, which, as before stated, acts upon the arm, moving'jend lt' thereof forward, and end 7: thereof backward lo being attached by 1J to lever n, draws the long end'thereot forward, and applies the forward brake of the rear'truck, by its action on the chains M', fastened thereto; 7s' beinglikewise attached by p. to lever m,draws the long end thereofbackward, and thus applies the forward brakes of the forward truck, by means of theeha-ins r a, fastened thereto.

If it is desiredto move in the opposite direction, except when backing, unwind the brake-wheel fr, and wind up the opposite, il, thereby moving the end of arm j to the rear, and then, bythe pressure above mentioned, the same effect is produced, except by a different set of brakes, the forward brakes always actino. Y

When it is desired to back the train, no change is necessary', as Vthe brake-blocks are -so constructed as to ly up and out of the way, by a reverse motion of the wheels; said blocks being hung, as shown in iig. 5, by the pivots A and B, are thrown out ot' use by a backward movement, and in the position shown in 6.

g1 do hereby reserve to myself the right exclusively to fasten all the bars C C on cach truck together by a strap or rod, thereby subjecting all to one mot-ion, and also of usingonly threevof the bars G C to each Y truck, if I should desire so to do.

Having thus described my invention,

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

1. A car-brake, the power to which is applied by means of the false bumper XV r/ gf, by the pressure 94ans thereon, occasioned by stopping the'engine, or other 3. The self-adjusting blocks or brake-pads d, in conmeans of locomotion attac-hed to the car, in oonneenetion with the parts above mentioned and claimed, tion with the rods or ehains p p', q q', r 0", springs 7er, as herein described, and for the purpose set forth. 1 coils 5, and levers if, 7c, l, fm, al, and o, vSubstantially as The above speeioation of my invention signed by herein described, and for the purpose set forth. me, this 6th day of February, 1869.
