BRAKE surron'rrne ANDY LEVELIIIG nnvrcn.

To all whom it may concern:

Be it known that I, ARMANI) II. PEYOKE, 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 and Leveling Devices, of whichthe following is a specification.

This invention relates to a 'brakesupporting and leveling device.

One of the objects of this invention is to simplify and improve brake supporting and leveling devices, and to combine parts in a novel manner for reducing the amount of necessary material. 7

Another object is'to provide an improved combination of brake supporting and leveling devices and safety bar hangers, adapted to meet the various requirements for successful operation.

These and other objects are accomplished by means of the arrangement disclosed by the accompanying sheet of drawings, in which,

Figure 1 is a fragmentary side-elevation of a railway car truck, embodying my invention.

Fig. 2 is a fragmentary end, view of the supporting and leveling devicemeans.

Fig. 3 is a detail sectionalview taken in the plane of line 33 of Fig. 1.

Fig. 4: is a fragmentary side elevation of a railwaycar truck, embodying a modification of my invention, and

Fig. 5 is a detail partial end elevation of the same.

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

Referring first to Figs. 1, 2 and 3 of the drawings, it will be noted that I have shown my invention as applied to a railway car truck, including a spring plank 10, under which is mounted a safety bar 11, which extends to opposite sides of the spring plank underneath brake beams, including a compression member 12, a tension member 13 and a fulcrum 14, extending between said compression and tension members. The function of the safety bar 11, is to catch the brake beam and prevent the latter from falling to the ground in the event that it becomes detached from its normal hangings. The safety bar 11 is supported in-two brack-' the preferred Specification of Letters latent. P te t d Ma 11, 192.0,

'App1ication filed April 22, 1918. Serial No. 229,937;

ets 15, which are provided with spaced legs, having apertures therein, for'the reception of the safety bar. These brackets preferably are secured to the spring plank, and interposed between the inner legs of the brackets 15, there is secured to the safety bar a double spring clip 16, theends of which engage the inner legs of the bracket 15 for positively locking the safety bar against longitudinal movement.

Formed ntegrally with the bracket 15 in each case, is a leveling member 17, preferably of spring material, said member ex-. tending over the brake beam andterminating in a loop 18 in which a balance hanger or link 19 is pivotally connected by a pin or other pivotal connection 20. The lower end of the hanger 19 in each .case is pivotally connected tothe outer end ofthe fulcrum, 1 1, whereby the brake beam is main tained in a balancedcondition so that the brake shoes, carried by heads mounted on the brake'beams will be maintained in concentricity with respectv to the braking surfaces of the associated wheels 21; This spring leveling device 17 permits the necessary movement in a vertical direction, in

accordance with operating conditions, and

at the same time properly supports the brake beam in the manner hereinabove mentioned.

Referring to Figs. 4 and 5 wherein I show embodiment of this invention, it will be noted that the safety bar 22 is hung in apertured brackets 23, said brackets 23 being formed by bending the material back on itself and providing the upper end of one leg with a hooked portion 24, overhanging a flange, in each case, of the spring plank 25, the brackets, in addition being otherwise secured to the spring plank by rivets 26. The lower ends of the brackets are formed by upsetting the strip material to form a head 27, broadened out to give considerable bearing surface for the safety bar 22. The safety bar in this case is pro vided with two spring clips 28, each of which engages its corresponding bracket 23 to prevent longitudinal movement of the safety bar. Formed integrally with each of the brackets 23 is an overhanging leveling member 29, preferably of spring material connected to the brake beam 30, in the same tions and operation of the arrangement dis-' closed in Figs. 4 and 5 are the same as the arrangement disclosed in the other figures of the drawing.

There a single central safety bar is used the resilient leveling device also may'be arranged centrally. If two .safety bars are used, one at each side of the truck, the' spring leveling device may be offset having its outer end in each case terminate centrally with respect to the brake beam.

It is evident that there may be various other modifications of my invention and it is my intention to cover-all such modifications,

which do not involve a departure from the of a brake beam, a rigid safety bar therefor,

separate means for supporting said safety bar and extending into the proximity of said brake beam, and a supporting connection between said brake beam and extending portion of said means.

4. In brake mechanism, the combination of a truss brake beam, a safety bar therefor, a member forming a hanger for said safety bar and also having a portion extending over said brake beam, and a hanger connecting said overhanging portion and of a truss brake beam, a safety bar therefor, 4 a member forming a hanger for said safety bar and also having a resilient-member exte'ndingover the brake beam, and a hanger connecting said overhanging portion and the tension rod portion of said brake beam 5 for maintaining the latter in balanced con dition.

6. In brake mechanism, the combination of a spring plank, a member secured thereto having a bracket portion and a supporting 5 portion, a safety bar carriedby said'bracket portion, a-brake beam overlying. said safety bar, and a hanger connectingsaid brake beam and supporting portion.

7. In brake mechanism, the combination 6 of a brake beam, a rigid safety bar therefor, a member supporting said safety barand terminating at a point adjacent the brake beam, and a connection between said member and brake beam. Y I f6 8. Inbrake mechanism, the combination of a brake beam, a movably mounted safety bar therefor, a member having a bracket portion for supporting said safety. bar, means normally preventing movement of 7 said safety bar, said member being operatively connected to said brake beam. for

, maintaining the latter in-balancedcondition.
