BRAKE-STAND FOR CARS.

TSEECIFIGATION forming part of Letters Patent No. 694,191, dated February 25, 1902. Application filed October 15, 1901. Serial No. 78,750. (No model.)

To all whom, it may concern.-

Be it known that 1, JOHN W. PUCKETT, a citizen of the United States, residing at Manchester, Chesterfield county, Virginia, have invented certain new and useful Improvements in Brake-Stands for Cars, of which the following is a specification.

My invention relates to brake-stands for railway-cars, the same residing particularly in anovel means of mounting the brake-staff whereby it may be swung from a vertical to a horizontal position without throwing it out of operative connection with the brakes.

In the loading of freight-cars it is frequently The details of my invention will hereinafter "appear, and the novel features thereof will be set forth in the claims.

} In the drawings forming part of this specification, Figure 1 is an end elevation of a carbody provided with my improvements. Fig. 2 is a vertical section of the same, the section being taken through the brake-staff. Fig. 3 .335 is a sectional plan view showing the upper 'end of the brake-stand. Fig. 4 is a detail front elevation of the back plate or bracket,

and Fig. 5 is a rear elevation of the staff-carrying plate or frame.

Like reference-numerals indicatelike parts in the difierent views.

- In the embodiment of my invention here- 'in shown I secure to the front of the car-body l a base-plate or bracket 2, which projects 4 5 down below the bottom of the car-body and has an opening 3 extending through it. Around this opening, on the front side of the plate 2, is an outwardly-extending rib 4, which lies parallel to the front face of the plate 2, forming an annular groove 5. The rib 4 is cut away or notched at one point, as shown at 6,

found necessary or desirable to have the load forming an entrance into the annulargroove or channel 5. This notched or cut-away portion has been shown as being located at the upper edge of the rib 4; but it is obvious that the same may be otherwise disposed. Above the rib 4 and groove 5 the plate 2 has secured to or formed integral with it a secondary plate or thickened portion 7, the lower edge of which is concave, as shown at 8, and concentric with the rib 4. The upper edge of. the plate, enlargement, or thickened portion 7 is convex and concentric in its curvature with the rib 4 and ,is also recessed to form with the plate 2 a groove .9 and an upwardly-extending lockin g projection 10. Pivoted in the plate 2, adjacent to. one of the side edges of the enlargement or thickened portion 7 thereon, is a dog or stop 11, which normally projects outwardly beyond the face of the .enlarged portion 7, but is adapted to moveupwardly and inwardly, so as to fit within the recess or opening 12 in the plate 2.

Cooperating with the back plate or bracket 2 is what may be termed a staff-carrying v) plate or frame 13. The same is formed with a circular opening 14, which when the parts are in their assembled positions registers with the opening 3 in the plate 2. Secured to or .formedintegral with the plate or frame 13 on,

the front side thereof are the lugs 15 16, the same having openings extending therethrough, which brake-staff 17. Any other suitable form of bearings for this staff may, however, be sub-.

stituted for the lugs 15 and 16. The said staff 17 is provided, as usual, with an operating-wheel 18 upon its upper end and has se- 7 cured to it at a point just above the upper With this ratchetg lug 15 a ratchet-wheel 19.

constitute bearings for the wheel cooperates the pawl or dog 20 for preventing reverse movement of the staff. The

said pawl or dog is pivoted in a lug or projec tion 21 on the frame or plate 13. On the rear side of the staff-carrying frame are the inwardly-extending lugs or projections 22 23, the lug 23 being of a size corresponding with that of the notch 6 in the rib 4 and the lug 22 being of greater length. These lugs lie in the same plane with each other and are preferably located on opposite sides of the opening 14. Their inner edges are concave, and the curvature thereof isconcentric with that of the opening 14. The said lugs when the parts of the device are in operative positions fit and move within the groove 5 on the back plate or bracket 2, as is clearly shown in the drawings. In assembling the parts the staff-carrying frame or plate 13 is turned so that the operating-wheel 18 on the staff 17 extends downwardly. The lug 22 is then introduced intothe groove 5 and the lug 23 is passed through the notch 6 into the groove 5, when said frame 13 is swung around to a vertical position, with the operating-wheel 18 on the staff 17 uppermost. The lugs 22 and 23 move freely in the groove 5, and it is impossible for the same to become disconnected from said groove unless the lug 23 be brought around to the notch 6. Above the lug 22 on the rear face of the stafi-carrying frame or plate 13 is formed an overhanging flange 24, havinga concave lower edge and producing a groove orchannel between it and the body of the plate 13. When the staff 17 is inits vertical position, the flange 24L fits within the groove- 9 behind the locking projection 10 and said locking projection 10 fits within the groove 25 in front of the flange 24. This construction provides for a locking connection between the base-plate or bracket 2 and the staff-carrying frame or plate 13 in addition to that formed by the lugs 23 and 24 and the rib 4. Danger of displacement or outward movement of the ployed, and the same may be secured in place I in any other suitablemanner.

plate or frame 13 independent of the plate or bracket 2 is thereby effectually prevented.

The back plate or bracket 2 is secured to the front of the car-body 1 by means of screws 26, bolts, or other analogous devices. By'one of said screws is secured in place a stop. 27. This stop hasbeen shown in the form of a block of metal, through which the screw 26 passes; but any other form of stop maybe em-v Now it will be observed that when the stafi 17 is in its vertical position'mov'ement of the frame 13, which carries said st-afi, is prevented in one direction by thedog 11, and movement of said frame in the opposite direction is prevented by the stop 27. As long asthe stop 27 remains in place, therefore, it is impossible to turn the stafE-carryingframe 13 to the right to bring the lug 23 opposite the notch 6, and'consequently it is impossible to disconnect said plate or frame from the back plate or bracket 2.

Movement of said staff-carrying frame 13 beyond" a certain distance is prevented in the opposite direction by the engagement of the lug or projection 28 on said frame with the enlarged portion 7 on the back plate 2. This lug or projection 28 is -so disposed that it will permit of a movement of the frame or plate 13' from avertical to a horizontal position and no, farther. When, therefore, it is'desired to load the car-body 1 beyond the ends of the same, and it is" consequently desirable to get the brake-staff 17 outof the way, it is merely necparts from their horizontal to their vertical positions, no locking or detent mechanism is necessary to be released, it being merely essential to elevate the free end. of the stafi 17, which movement will cause a swinging to the right of the plate or frame 13.

same out of the way automatically, and when said frame reaches its vertical position, which is determined by its. striking against the stop 27, said dog 11 returns to its normal outward position, and turning movement in either di-' rection'of the frame 13 and the parts carried thereby is prevented. I

It should be stated, ofcourse, that the stafi 17 has connectedto it adjacent to. its lower end the chain 29, which leads rearwardly to the brake or brakes and is adapted. to. be

wound upon said staff. This chain29 passes through the

openings

14 and 3 and is adapted to be wound'npon the. staff 17 in any position to which said stafi may be turned.

My invention has been shown in connection with a coupler 30 and an operating-lever .31 for the coupling-pin in order to showthat the staff 17 may be shifted from one of its positions to the other withoutrinterfering with the operation of said coupler or the uncoupling mechanism therefor.

The preferred form of .my invention has been shown and described; .but'I realize the fact that many changes may be made in the detailsof construction as well as in the size, proportion, and arrangementof the different parts. I therefore do not desire to be limited to any of the specific details herein shown and described except as defined in the following claims. p
