SUPPORTING .Aam t e-mum DEVICE FOR cLasr-nnaKns.
Application fileaa rii 5, 1913. Serial No. 226,908.
To all whom it may concern:
Be it known that I, ARMAND H. PEYGKE, 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 Supporting and Leveling Devices for Clasp-Brakes, of which the following is a specification.
This invention relates to a supporting and leveling device for clasp brakes.
One of the objects of the invention is to simplify and improve supporting and leveling devices for clasp brakes.
Another object is to provide a pull rod supporting and leveling device adapted to meet the requirements for successful commercial operation.
Generally speaking, these and other objects are accomplished by providing, in brake mechanism, the combination of a pull rod and a hanger therefor forged around the pull rod.
The invention is illustrated on the accompanying sheet of drawings, in which- Figure 1 is a fragmentary plan view of a railway car truck embodying my inventlon;
Fig. 2 is a fragmentary side elevation of the same; and,
Fig. 8 is a sectional View taken in the plane of line 33 of Fig. 2 showing a bracket for supporting the hanger.
The various novel features of the invention will be apparent from the following description and drawings and will be particularly pointed out in the appended claims.
Referring to the drawings, it w1ll be noted that I have shown a railway car truck 10 carried by the car wheels 11, only one of which is shown. Mounted upon opposite sides of each pair of wheels is a brake beam. 12 carrying brake heads 13 with brake shoes 1-1 for frictionally engaging the wheels. The brake beams are provided with fulcrums 15, to each of which is pivotally connected a hanger 16 which assists the regular hangers 17 in supporting the brake rigging. The lower ends of brake levers 18 and 19 are plvotally connected to the fulcrums 15, and connecting these brake levers intermedlate their ends is a pull rod 20. The pull rods must be supported and kept properly leveled in order that the braking mechanism may operate properly.
I have provided an improved and s mplified supporting and leveling device whlch 1n- Specification of Letters Patent.
Patented Nov. 18:, 1 91 9.
cludes a hanger 21, the lower end ofwhich is forged around the pull rod 20 in the form of an elongated loop 22. The pull rod is provided with a plurality of projections 23 between which is formed a seat 24 for the lower end of the loop 22 of the hanger 21. The seat 24 in each case, is formed just outside of the jaws of the pull rod which embraces an intermediate portion of a brake lever. The upper end of each of the pull rod hangers is provided with an eye 25, through which a pin 27 may be passed for supporting the hanger 21, said pin also pass ing through openings in the loop of a bracket 28, which may be secured to the wheel guard at 29 or to any other suitable support. The hangers 21, therefore, are pivotally mounted in line with each other in a manner to permit the pull rod 20 to swing in accordance with braking conditions and at all times maintain the pull rod in a plane parallel with the tracks. By referring to Fig. 3 of the drawings, it will be noted that sufficient clearance is left in the elongated loop to permit the hanger to swing a considerable amount. The arrangement is such however, that it is not possible for the loop 22 of the hanger to move out of its seat 24E in the pull rod.
By means of this hanger arrangement the pull rod, such as the intermediate pull rod herein shown, may be supported and maintained parallel with the track in a simple and improved manner by forging the lower end of the hangers around the pull rod, thereby obviating the necessity of a pin connection between the pull rods and their hangers.
It is evident that there may be modifications of the invention herein shown and described, and it is my intention to cover all such modifications falling within the spirit and scope of the following claims.
I claim:
1. In brake mechanism, the combination of a pull rod with a seat formed therein and a hanger for said pull rod occupying the seat in said pull rod.
2. In brake mechanism, the combination of brakes, levers operatively connected thereto, a pull rod connecting said brake levers and having a seat formed therein, and a supporting hanger for said pull rod occupying the seat in said pull rod.
3. In brake mechanism, the combination rod to permit a free relative movement therebetween but not enough to permit the loop of the hanger from disengaging said seat.
Signed at Chicago, Illinois, this 28th day of March, 1918.
ARMAND H. PEYCKE.
