BRAKE MECHANISM.

To all whom it may concern:

Be it known that I, JUs'rUs J. Ross, a

citizen of the United States of America, and

resident of Fairmont, county of Marion, and State of lVest Virginia, have invented certain new and useful Improvements in Brake Mechanism, of which the following is a specification.

This invention relates to improvements in car-controlling brakes, and 'more particularly to a brake adapted for use on minetipples whereby the movement of thecars being loaded at the tipple may be controlled; and it consists in theparticular construction, arrangement and combination of parts which will hereinafter be fully described.

The primary object of the invention is to provide a simple, positive and convenientlyoperated drum brake for use on loading tipples and the like whereby the movement of railway cars from one position to another with respect to the loading chute of the tipple may be readily controlled from the top of the tipple and, consequently, without resorting to the use of the brakes on the .cars, resulting in the need of a man for operating such car brakes being dispensed with.

As is well known, the railway tracks at a loading tipple are usually arranged on a slight incline for facilitatii'ig the forward movement of the cars as needed for loading and after loading. By means of the present invention, cars are readily releasedv and allowed to move slowly forward down the incline,'and are readily stopped at any desired point,

A further object of the invention is to provide a strong and durable brake of the character mentioned, the construction being such as to readily withstand the great strains and heavy shocks to which it is liable to be subjected.

'In describing the invention in detail, reference is herein had to the accompanying drawin s formin :1 )art of this s cifica-- t-ion, in which Figure 1 is a front elevation of the inventionmounted in operative position; Fig. 2 is a side elevation of the-same; Fig. 3 is a top plan View of the same; and Figs. 4 and 5 are sections taken respectively on the lines 4-4 and 55, .Fig. 3.

Referring to said drawings, in which like reference characters designate like parts throughout the several views-1 mdlcates Specifieation of Letters Patent.

Application filed March a, 1909. serial No. 481,127.

the base-plate of a frame which is adapted to be mounted upon a beam 2, or in other appropriate position at the top of a loading tipple, said frame comprising said base-plate l and a pair of outwardly-directed parallel supporting arms 3 and 4- which are preferably integral with the plate 1 and which are terminated by shaft-bearing portions 5 and 6, inwhich latter is journaled a shaft 7. A drum 8 is keyed upon the shaft 7 between the arms 3 and 4 by means of a key 9 fitting in registering mortises provided in said shaft and in the drum, as is clearly shown in Figs. 4 and 5, and upon this drum is wound a cable 10 one end of Which is appropriately attached to 'said drum, as shown in Fig. 4. Said cable'is passed downward from the drum to and about a sheave 11, and thence forward for connecting to a car. -A brake-wheel 12 is fixed uponthe shaft 7 adjacent to the bearing portion 5, a key v 13 being fitted into registering mortises provided insaid shaft and said wheel, as shown in Figs. 2 and 5. Partially encircling the Wheel 12 is a flexible metal brake-band 14, on the inner surface of which is carried a sectional brake-shoe 15 of wood or other suitable material adapted for frictionally engaging said wheel. One end of the brakeband 14 is connected by means of a strap 16 to the outer end of a forwardly-directed supportl? which is carried by, or which is formed integral with, the frame, and the opposite end of said band is connected by free'end of the lever 19 is a weight 21, preferably-adjustable, whereby force is applied to the brake-band for normally maintaining the brake applied to the wheel, 12, resulting in the drum 8 being maintained in a stationary position.

.The support 17 is formed integral with and receives support from the arm 3, as is clearly shown in Fig. 2. Said support is of hollow box-like formation, providing two parallel vertical members 17, an upper cross member 17*. and a downwardly and inwardly inclined member 17. The inner member 17) is in vertical alinement with the hangs the brake-wheel in appropriate position for having the lever 19 mounted thereagainst in proper relation to the brakeband ll. The two members 17 serve as supports or separated bearings in which are held the strap-attaching bolt 22 and the pivot-bolt 23.

in practice, the weight 21 occupies position on the lever which will normally maintain the drum stationary. When the free end of the cable has been attached to a car and it is desired to allow the car to move forward down the inclined track, the weight is either moved forward along the lever or the free end of the latter is raised relieving the normal pressure of the brakeshoe upon the brakewheel. This action al.- lows the shaft 7 and the drum 8 to turn, paying out the cable 10. it is obvious that by manipulation of the lever the speed of the car in moving forwardmay be readily controlled and the car may be stopped at any desired point.

The device may be operated by the same person who controls the dumping of the .znine cars at the top of the tipple.

Having thus described my invention, what it claim new, and desire to secure by Letters Patent, is-

Leashes In a drum-brake for use on loading'tipplesya base-plate adapted for mounting in vertical, position; a pair of parallel outstanding arms carried by said base-plate; a shaft journaled in said arms; a drum fixed on said shaft; a brake-wheel fixed on said shaft; a hollow box-like support connected to one of said arms, said support comprising a pair of parallel vertical members, an upper cross-member, and a downwardly and inwardly inclined member, the inner of the vertical members being in vertical aline-.

ment with said one arm and the outer of said members being in overhanging relation to said brake-wheel; a brake-band encircling said bra-kewheel; a strap connecting one end of said bralre band to the outer end or" said support; a lever pivoted intermediate its ends against the brake-wheel overhanging member and having an end pivotally connected to the opposite end of said strap, and means for adjusting said brake-band.

in testimony whereof ll aflix my signa v fmeion Gnarrins.
