dilferent arrangements of)m'y brake To all lwko/m, it may concern: -4 eral Beit known that I, CHARLES E. ROGHAM- mechanism. BEAU, a citizen ofthe United States, and a Referring particularly to the drawings, I resident of St. Joseph, in the county 'Of. show at 10 what may be regarded as a base 5 Buchanan and State of Missouri, have 1nplate adapted to be secured in a preferably 60 vented a new and Improved Car-Brake, of 'vertical plane at any convenient point on which the following'is a full,- clear, and exthe end or side of a car and to which will Aact description. i be rigidly and permanently connected a This invention relates to railway rolling housing or casing 11. The housing is shown stock and has particular reference to an 1mas comprising a rear wall 12, a rim 13 and a 65 proved form of hand loperated brake for face plate or cover 14. A set of bolts 16 freight cars or the like, whereby the train extend throughA the base plate 10 and man or brakeman will have better control thraugh'the casing securing the cover tothe of a car, especially in a switch yard where rim and the casin to the base plate. the cars are being handled in detached rela- Within the casmg is a drum 17 having 70 I tion to the engine than has heretofore been portions 18 and 19 of different diameters possible with the ordinary' forms of brakes. connected preferably by a spiral groove 20. Among the objects of this invention is to To the larger portion 18 is connected any provide a brake or a set of brake mechanisms suitable flexible draft connection shown as 20 whereby a car may be under practically pera chain 21, -the same being guided over said 75 fect control of the brakeman when operate spiral groove and the smaller drum portion, either from the top of the car or adjacent and extending thence outward through the either end thereof, the brake mechanisms berim 13 and guided over any suitably aring so disposed with respect to the car body -ranged directlon pulley 22. To the drum 17 or frame as to enable the brakeman-to opis secured a gear wheel 23 adapted to be 80 erate it freely by one hand while hanging driven by a pinion 24 mounted Aupon an upon the lcar with his feet and the other arbor 25 adapted to be driven by a hand hand and irrespective of the condition of the wheel26. The arbor 25 and the axis 27 of load on the same or the adjacent car.

On freight mannen The length of the chain and the cars as usually constructed the brakeman arrangement thereof upon the drum will be is unable to see the yard and the various cars such that the first loperation of the hand therein while he is in the act of controlling Whl will cause the slack in the chain to l 40 the car being switched and many serious be taken up quickly on the larger portion 18 95 accidents arise because of such fact. and when power is required for the setting The foregoing objects are attained and the, of the brakes the force will be applied aforesaid difficulties are overcome byv the through the smaller portion of the drum 19. mechanism to be hereinafter fully described To lock the brake when set I prefer to use and claimed and shown in the drawings acratchet wheel 28 rigidly connected to the 100 companying this specification in which like drum and gear wheel 23. Coperating with characters of reference indicate correspondsaid ratchet wheel is a pawl 29 pivoted at ing parts in all the views, and in which 30 within the casing.

33 a rod 34 extending outwardly through the casing rim and terminating in a. linger. piece 35 whereby it may be moved to shift the Weight from either end of the pawl to the other. In the position indicated in full lines in Fig.v 1, the weight will cause thel pawl to engage the ratchet wheel and hence will prevent the reverse rotation thereof. When it is desired to release the brake, the trainman will shift the weight to the other end of the pawl by pulling outward upon the rod 34 as indicated in dotted lines. `The pawl will then be so counterbalanced as to swing free from the ratchet wheel.

In Fig. 3 is shown a box car A having a plurality of my brake operating devices connected thereto whereby the brakes may be set either from the top of the car or from a lower corner- By this arrangement a brakeman on top of the car may have control thereof without climbing down or a brakeman adjacent the ground may control the car Without being required to climb to It frequentlyv happens' in shifting the cars in a yard that a brakeman does not have time to change his. position with respect to the bottom or top of a car so as to control the speed ofthe car before it strikes the car to which it is to be coupled.

In Fig. 4 is shown a flat car B adapted to be loaded to substantially its full length and hence .the brake operating mechanism will be preferably placed-below the plane of the floor thereof as indicated o-n the side where it may be operated either from the ground or by hanging upon the side of the car where the brakeman will have a clear view of the yard and his proximity to any cars that may be therein.

The several part-s of the mechanism may be made of any suitable materials and thel relative sizes and proportions vthereof as well as the specic details of construction may be varied to considerable extent without departing from the spirit of the invention.

Having thus described my invention, what I claim as new and desire to'secure by Letters Patent is 1. The combination with a railway car, of a drum, a brake chain connected tothe d`rum`, means to rotate the drum to tighten the chain, rotation ofthe drum, said controlling means comprising a ratchet ing a slidable as set forth.

2L The combination with a railway car, of a drum, a brake chain connectedto the drum, means to rotate the drum to tighten lthe chain, and means to control the reverse rotation of the drum, said controlling means comprising a'ratchet wheel, a pawl pivoted intermediate its ends, and a weight slidable from one end of' the pawl vto the other, substantially as set forth.

`3. In a railway brake operating mechanism, the combination of'a chain, a drum t0 which the chain is connected, a gear wheel and a ratchet wheel secured to the drum, a pinion meshing with said gear to rotate the same to tighten the chain, a pawl coperating with said ratchet wheel, said pawl being pivotedintermediate its ends on a horizontal axis, a weight associated with the pawl and slidable from one end of the same tothe other beyond said pivot, and a rod connected to the `weight whereby it may be moved in either direction, substantially as set forth.

In testimony Whereof- I have signed my weight thereon., substantially and means to control the reverse i wheel and a pawl havname to this specilication in the presence of two subscribing witnesses.
