JOHN GREEN, OF ST. LOUIS, MISSOURI, ASSIGNOR TO COMMONWEALTH STEEL COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION.
SUPPORT FOR CAR-TRUCK BOLSTERS.
SPECIFICATION forming part of Letters Patent No. 776,235, dated November 29, 1904.
Application led' March 24, 1904.
To all whom, it nuty concern:
Be it known that I, JOHN GREEN, a citizen of the United States, residing in the `city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Supports for Car-Truck Bolsters, of which the following is a full, clear, and exact description, reference being` had to lthe accompanying drawings, forming part of this specification.
My invention relates to a moving support for car-truck bolsters, and has for its object to furnish, in connection with a cast truckbolster, a single-piece saddle that engages the ends of the cast bolster at the lower side thereof only and rides in engagement with the moving bolster-sustaining member situated beneath the bolster ends.
My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.
Figure I is a perspective view of one end of a truck-bolster made to suit my improved saddle. Fig. II is a perspective view of the saddle. Fig. III is a longitudial section of the bolster-support. Fig. IV is a transverse section taken on lin-e IV IV, FigfIII.
l designates a portion of theside frame of a railway-car truck in which column-bolts 2 are seated.
3 designates bolster-guides fitted to the upper portions of the column-bolts. Y
4L is a bed seated within the side frame portion 1 at its bottom and having uprights 5, through which the column-bolts 2 pass,
6 is a roller-bed mounted on the bed 4 and the top surface of which' serves as a runway for rollers 7. Y Y
8 is a carriage that surmounts the rollers 7 and rides thereon with freedom. This carriage serves as a spring-seat to receive the bolster-supporting springs 9, and it is provided with vertical side guides 10.
The parts thus far described are old and no invention per s@ is herein claimed for them.
1l designates a cast truck-bolster that is provided at its lower side and at the edges thereof with sockets 12.
13 is a saddle of inverted-U shape, having a plain upper surface and provided with bosses 14, that enter the sockets 12 in the bolster l1.
serai No. 199,767. (No moda.)
By the construction of bolster-support herel in shown and described, in which the bolster is in the form of a single integral casting and the saddle 13 is likewise in the form of a single integral casting and seated whollyT beneath the bolster, I produce a structure that is much less expensive to manufacture than similar structures heretofore in use and at the same time furnish a structure that embodies a maximum of strength and is of such simple nature as to most materially lessen the liability of breakage in service, thereby reducing' the cost ofrepairs in bolster-supports to a minimum.
I claim as my inventionl. In a support for car-truck holsters, the
combination of a carriage o1' sustaining member, a bolster, and asaddle having detachable socket connection with said bolster at its bottom and adjacent to its sides; said saddle having engagement with said sustaining member, substantially as set forth.
2. In a support for eartruck holsters, the combination of a carriage or sustaining member, a bolster having sockets in its lower side, a saddle positioned beneath said bolster, and bosses integral with said'saddle and seating in said sockets; said -saddle having engagement with said sustaining member, substantially as set forth.
8. In a support for cartruck bolsters, the combination of a carriage or sustaining member, a bolster, and a saddle having non-shiftable socket connection with said bolster; said saddle having engagement with said sustaining member, substantially as set forth.
JOI-IN GREEN.
In presence of-n E. S. KNIGHT, BLANCHE HOGAN.
