Letters Patent No. 112,954,11atea March 21, 1871.

The Schedule referred to in theseLetten Patent and making part of thesame.

To all whom it may concern-.-

Be it known that I, J osnPH PARADIS, of Brooklyn, in thecounty of Kings and State of New York, have invented an Improvement inv Stopping and Starting Railroad-Gars; and the following is declared to be a correct description thereof.

This invention is for storing the force exerted in stopping the car and applying the same -to starting the car, thereby lessening the strain upon the horses and facilitating the starting of the car with rapidity, even when ascending an incline.

I am aware that many devices havebeen proposed for accomplishing the before-named result. i

My invention relates to the construction and arrangement ofthe parts, whereby they are rendered compact, strong, easily managed, and durable.

In the drawing--V Figure 1 is an inverted plan of a car with my improvement applied to the Wheels and axles, and

Figure 2 is an elevation, the wheels on one side heing removed.

The car body or platform a is to be of any desired size or shape, and the wheels b h and cc, u'pon the axles d and e, are to be of' 4any usual character.

Upon the axle d is a chain-barreh'f, securely fastened in place or formed upon such axle d, and upon the axle e is a similarbarrehf', and upon the inner ends of thesel barrels f f lare ratchet-wheels, i.' v

Upon each axle d or e is a second chain-barrel, h or 11', that is free to turn upon such axle, and to be moved endwise by the lever l or l', so that the disk n or n'and pawl o may be in contact with the ratchet-wheel t', or s'uciently distant therefrom to be out of contact therewith. v The springs are either helical or elliptical, or a compound of several springs, that are arranged so as to be compressed by a movement longitudinally of the car.-

I have shown helical springs around the rod 1J, con nected to the bow or elliptic spring p', and 1' lr are compressing followers, that slide upon the rod p andare connected with the chains tand fu.

The chain t passes around the barrels h' and f to the barrel e, upon the vertical shaft c', which is provided with a handle at its upper end, and the chain u passes in an opposite direct-ion around the barrels h andf' to the barrel w on the vertical shaft fw', which is also provided with a handle.

Itis now to be understood that the barrel f, disk n,

and paw] `o at the forward end of the car are to be thrown ont of gear, so as to remain stationaryas the wheels c and axle revolve, and that'. the barrel-f', disk n', and pawl o at the rear axle either revolve with that axle, if the chain t around the barrel h' hangs lcomparatively loosely; or, if-said chain'is attached to the said barrel near the middle of three or four turns of the chain around the'barrel, then the disk, barrel, and; pawl will remain stationary, while the teeth of the ratchetwheel underrun the pawls as the axle and Wheels lre- Y volve.

When the chain tis tightened by the handle 3, shaft v', and barrel c, then the chain is drawn upon .by the barrel f as it revolves with the wheels c, and the barrel h is simultaneously turned and the springs compressed until, by the resistance of the springs, the revolution of the wheels c is stopped,the slack of the chain t being wound upon the barrel lu.

The parts are held by the handle 3 until the car is to be started, when, upon slackening the chain t, the springs p Willbe free to act upon the-chain t and revolve the barrel It', disk n', and pawl, and through them the wheels b b and axle e, in the. direction in Vwhich they move as the oar moves forward; thereby the force that is stored in the springs in the act of stopping the car" is expended in starting the car, either on an incline or upon a level track.

When the car' is being drawn in the reverse direction the disk 'n' and pawl o are moved to disconnect from the ratchet-wheel i, and the parts at the other end are connected, so that thestopping and starting mechan-V ism i s available at either end ot' the car.

Wire ropes may be substituted-for chains. Thisapparatus may be used singly, to work from only one end. o'f the car.

I claim as my invention- The barrel h', disk u', pawl, and ratchet on one axle, and arbarrel, f, on the other axle, inl combination with the springs and a rope or chain -passing around said barrels and leading to a hand-shaft and barrel for compressing the spring in stopping the car, and applying its vpower in startin g the car, substantially as set forth.

Signed by me this 30th day of November, A. D.
