ALBERT MCCALLUM, or SPOKANE, WASHINGTON.
HAND-BRAKE ron cA'ns.
Specification of Letters, Patent.
To all who-m z'timag concern:
Be iti known that ALBERT: L. MGGALLUM,
a citizen of the United States of America,
residing'at Spokane; inthe countyofSpokane and State ofWas'h'ington, hasin'vented improved COIHLQCiZlOlFbGtWQGH illie" brake and the means for operating the same: to pro-- vide a connection whereby the means for operating the same may be set at different locations on the top of the car body and at other places on the car where desired instead of being arbitrarily placed at one loca tion, such as at the end of the car.
A further object is to provide an improved method for operating the brakes. Other and further objects and purposes .will be disclosed by the detail description hereinafter given and by the accompanying drawings forming a part of the specification in which Figure 1, is a broken-away side elevation of a box car equipped with my improved brake, 4
Fig. 2 is a vertical sectional view taken 011 the line 2 2 of Fig. 3,
Fig. 3, is a bottom view with my improved brake,
Fig. 4, is a broken-away front view of the mechanism for operating the brake, showing a manner of connecting the same With a car body and with a brake chain or cable,
Fig. 5, is a side view of the same, and
Fig. 6, is a broken-away rear View of the mechanism for operating the brake.
It is understood that my invention is applicable to boX, coal, flat and any and all cars and to all cars used in interstate commerce.
In the accompanying drawings I have shown my invention made applicable to a box car.
In a detail description in which like numerals refer to like parts throughout the several views, a rack 10 is shown secured of a car equipped to the top 11 of the car body 12 by means of U bolts 13 engaging the cross beams 14 of the car body 12 and being secured to the base 15 of the rack 10. Pivotally mounted on the rack 10, as at 16, is a segment 17, oppositely disposed to which is a lever 18, the two elements 17 and 18 being integral and being adapted to rotate on the pivot 16. In
the periphery of the segment 17 is groove- 18atone end of wh-ichisa'hook19. Mount ed onthe'lever 18 is a gravity pawl 39' adapted to engage the curved ratchet 20 of the rack 10.. The lever 18 is divided into" two portions 18 and 18 connected by a hinge 21 at one side thereof so 1 that in forcing the lever 18 in misdirection thelever WilLrem'ain rigid and in forcing thesaine-in the opposite direction the same will fold at the 'hi-n'ge2 li Theimproved brake mechanism in no way disturbs the under-car mechanism beyond the attachment of the floating beam 22which has the usual rod connection 23 reaching to and connectediwith the brake lever 24, by the operation of which the brake shoes 25 are set against the Wheels 26. Inasmuch as the car-brake construction shown embodies an air-brake, it is well to state that the piston rod 38 has a free action in the cylinder 27 and therefore will not interfere withthe free action of the beam 22 in connection with the handbrake herein described.
Mounted on the end of the beam 22, attached to the support 28 and secured to the body 12 of the car at 29, 30 and 31 are sheaves 32, 33, 34, 35 and 36. Attached to the support 28 is one end of a chain 37, the chain 37 engaging the sheaves-32, 33, 34., 35 and 36, the groove 18 in the segment 17 and being attached at its opposite end to the catch 19. By the connections shown between the lever 18 and the floating beam 22,
PatentedMay 7 1918 i of the arrow (Fig. 4) will operate the beam 22 to set the brake-shoes 25 against the wheels 26. The gravity pawl 39 engages the ratchet 20 and holds the brake until manually released. The fold-over character of the lever 18 is for the purpose of lowering the obstruction of the brake-operating mechanism in passing through subways, under wires, etc. 1
WVhile I have shown one specific form of my invention and only one application thereof, it is to be understood that I reserve the right to vary the details thereof and to make such varying applications thereof as are within the scope of the invention and covered by the claims. For instance, a cable might be substituted for the chain 37 and chain or cable adjusted and so placed that the beam may be operated to set and release the brake-shoes 25 with like effect as shown and herein illustrated and described.
Vhat is claimed is,
1. A hand brake mechanism for cars, adapted for independent action and C0111- bined with an air-brake mechanism, comprising a brake lever, rack and pawl mount-- ed on the car body, a floating beam underneath the car body adjacent the car trucks and connected with brake shoes, sheaves separately attached to the car body and to the floating beam and a cable connected at one end with said lever, passed over said sheaves and connected at the other end with the bottom of the car body.
2. A hand brake mechanism for cars,
adapted for independent action and combined with an air-brake mechanism, comprising a brake lever, rack and pawl mounted on the car body a segment attached to the lever, a floating beam underneath the car body adjacent the car trucks and connected with the brake shoes, sheaves separately attached to the car body and to the floating beam and a cable connected at one end with said segment, passed over said sheaves and connected at its other end with the bottom of the car body.
In testimony whereof I afiix my signature in presence of two witnesses.
