UNITED STATES PATENT OFFICE.
LOBEN L. WHITNEY, 0F HAMMOND, INDIANA, ASSIGNOR TO AMERICAN STEEL FOUNDRIES, OF CHICAGO, ILLINOIS, A CORPORATION OF NEW JERSEY.
SAFETY-GUARD AND LEVELING- DEVICE.
Specification of Batters Patent.
Patented Apr. 5, 1921.
Original application filed February 13, 1918, Serial No. 217,008. Divided and this application filed August 28, 1920. Serial No. 406,633.
To all whom it may concern:
Be it known that I, LOREN L. WHITNEY, a citizen of the United States, residin at Hammond, in the county of Lake and tate of Indiana, have invented certain new and useful Improvements in Safety-Guards and Leveling Devices, of which the following is a specification.
This invention relates to safety guards and leveling devices. and is a division of my application Serial No. 217,008, filed February 13, 1918.
The object of the invention is to simplify and improve combined safety guards and leveling devices in a manner tomeet service conditions.
This and other objects are accomplished by means of the arrangements disclosed on the accompanying sheet of drawings, in whioh- Figure 1 is a fragmentary side elevation of a railway car truck embodying my invention; and,
Fig. 2 is a similar view embodying a modification of the invention.
, Referring first to Fig. 1 of the drawings, it will be'noted that I have disclosed my invention in connection with a railway car truck including a spring plank 10, to which are connected depending apertured hangers 11 for supporting a rigid safety bar 12, the outer ends 13 of which are'inclined upwardly and each of which receives overlapping guiding hood portions 14 of a spring or resilient member 15 connected to the compression member 16 of the associated brake beam having a tension member 17 which rests upon an intermediate portion of the spring 15, which is bowed up for meeting the tension member at the proper place. By means of this arrangement the brake beam not only is prevented from falling to the tracks by the underlying end portions of the safety bar, but also maintained in proper position by means of the resilient members whereby the brake shoes are maintained in concentricity with the' day of August, 1920.
treads of the truck wheels.
In Fig. 2 of the drawings I have shown a rigid safety bar 18' which is straight throughout its length and is slidably engaged by a bent back portion 19 of a resilient member or spring 20 connected to the compression member 21 of the brake beam, which has a tension member 22 resting upon the intermediate curved or bowed portion of the resilient member 20 for the purpose hereinabove described in connection with Fig. 1.
There may be various modifications of the invention as herein particularly shown and described, and it is my intention to cover all such modifications which do not involve a departure from the spirit and scope of the following claims.
I claim:
1. In a railway car truck, the combination of a brake beam having compression and tension members, a safety bar underly ing same, and a member connected to the compression member slidably engaging the safety bar and upon which the tension mem' ber rests.
2. In a railway car truck, the combination of a brake beam having compression and tension members, a safety bar underlying the same, and a resilient member connected to the compression member slidably engaging the safety bar and upon which the tension member rests.
3. In a railway car truck, the combination of a brake beam having compression and tension members, a safety bar underlying same, and a member connected to the compression member slidably engaging the safety bar and having a bowed portion upon which the tension member rests.
4. In a railway car truck, the combination of a brake beam having compression and tension members, a safety bar underlying the same, and a member connected to the compression member having guide portions for slidably engaging the safety bar, said member acting'as a support for said tension member.
Signed at Hammond, Indiana, this 23rd LQREN L. WHITNEY.
