BRAKE-SUPPORTING MECHANISM.

Application led April 5, 1918.

- To all whom it may concern:

Be it known that I, ARMAND H. PEYCKE, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Brake-Supporting Mechanism, of which the Jfollowing is a specification.

This invention relates to brake supporting mechanism.

One object of the invention is to improve the means for supporting brake mechanism and for maintaining said mechanism yprop-- erly leveled.

Another object is to provide brake supporting mechanism adapted to meet the various requirements for successful commercial operation.

Generally speaking these and other objects are'accomplished by providing in a brake mechanism, a brake, a plurality of supporting members, means connected to said supporting members, and means carried by the aforesaid means to support said brake.

The invention is illustrated on the accompanying sheets of drawings in which- Figure 1 is a fragmentary side elevation of a railway car truck embodying my invention.

Fig. 2 is a detail view, showing the brake supporting and leveling means in front elevation.

Fig. 3 is a fragmentary side elevation of a railway car truck embodying a modification of my invention.

Fig. 4 is a detail front elevation of the modified form of supporting and leveling means, shown in Fig. 3.

Fig. 5 is a detail side elevation and Fig. 6 a detail front elevation of a modified connection between the safety bar and the resilient member which extends between the safety bars.

Fig. 7 is a fragmentary side elevation of a railway car truck embodying another modification of my invention.

Fig. S is a detail front elevation of the modified form of brake supporting and leveling means, shown in Fig. 7, including a three-point support arrangement,

serial No. 226,909.

Fig. 9 is a side elevation, and

Fig. 10 a front elevation of a modified form of supporting and leveling4 means, including a four-point support.

The various novel features of my invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.

Referring first to Figs. 1 and 2 of the drawings, it will be noted that I have shown my invention in connection with a railway car truck, including a spring plank 11 to which are secured hangers 12, two of which are arranged'at each of the opposite ends of the spring plank. Supported by the hangers 12 Iat each end of the spring plank is a safety bar 13, preferably locked to the safety hangers 12 by spring clips 14:. 1 These safety bars 13 underlie brake beams, the compression members 15 of which carry brake heads 16, having brake shoes 17, which engage the tread of the car wheels 18. Connected to each of the brake heads 16 is a hanger 19, the upper end of which is pivotally connected to any suitable part of the truck frame. Extending between the safety bars 13 near the ends thereof is a supportingl member 20, preferably in the form of a spring steel strap, the central portion of which is in the f orm of a loop and provided with openings for the reception of a pin 21 to which is pivotally connected a hanger 22 the lower end of which 4is pivotally connected at 23 to a fulcrum 24, extending-between the compression member 15 and tension member`2'5 of the brake beam. The hangers 19v support the brake rigging, including the brake beam, and hangers 22 overcome the unbalanced force of the brake beam thus maintaining the latter properly leveled in order that the braking surface of the brake shoe be maintained concentric with respect to the braking surface of the cooperating wheel. In this instance it will be noted that the hanger 22 is in the form of two relatively adjustable threaded members whereby the tension rod side of the brake beam may be raised 'or lowered with respect to the compression side thereof.

` the modifications shawn in Figa 3- and brake beamsv become detached from their.

normal hangings they willbecaught and prevented from falling to the tracks by the safety bars 13.

By referring toFigs'. 5 and 6, it will be noted that the spring member 20 has Aits ends twisted to an angle of 90o and perforated for receiving-thesafety bars13 and locked on the bar by oppositely arranged spring clips 27, instead of being secured to the safety bars 13'by keys28, as shown in Figs.1 and 2 andfinstead of rivets 29, as shown'in Figs. 3 and 4.

By referring to Figs. 7- and 8, disclosing a modification of my invention, it will be noted that instead of having the spring member extending vertically upwardly and transversely! and looped at its upper end, as shown in Figs. .1 to 4, inclusive, I haveprovided. a transversely extending spring 'steel member 30, which extends inra straight line between and is connected to the oppositely arranged safety bars 31. The middle portion ofthe spring member' 30 is provided with an inclinedpl'ate 32: for the reception of a sliding shoe-33,l connected to the fulcrum 34v extending'between the tension and compression members of the brake beam. In this modificatiomit will be'noted that only the regulan' hangers 35 are provided and that the tension rod sideof 'the fulcrum is supported by theplate 32 of the spring member 30, the'inclined plate acting as a suitable leveling device for guiding the brake shoe to proper relationship-with respect to the wheel when the brakes are applied. In 'this modification "it willbe noted that athree-point support is provided, two of said points ofsupport including hangers 35 arrangedv on opposite ends of the beams and the third, point of support being. the point'of contact between the spring plate 32 andv coperating sliding shoe In Figs.4 9 and 10 I'have shown a'modiiication of the arrangement shown in Figs. 7 and 8 andin which there are two sliding shoes 36 mounted upon the brake beam tension member 37 andv which slide u'pon' inclined. portions 38 ofl the spring.- 39' which extends between and is: connected to the safety bars or supports 40. In .this modification it will be noted thatthespring has twoV loops, one on each side'of its center and between thecenter'point and the point of con-v nection with the safety bars 40.

In allof these arrangements, the brake mechanism'is flexibly supportedin a manner There may be other modifications of the invention and it is my intention to cover all such modifications which do not depart from the spirit and scope of the following claims:

I': claim 1. In brakev mechanism, safety bars, a member extending therebetween, -a brake beam, brake heads carriedthereby,andVA a hangen for supporting said brake beam, said brake beam also being supported by*V the member.y extending between'said safety bars.`
