BOLSTER AND TRUCK MECHANISM FOR VEHICLES.
SPECIFICATION forming part of Letters Patent No. 730,688, dated June 9, 1903. Application filed September 29, 1902. Serial No. 125,298. (No model.
To all whom, zit may concern.-
Be it known that I, SPENCER OTIS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bolster and Truck Mechanism for Vehicles, of which the following is, a specification.
My invention relates to that class of trucks for vehicles having truck or gear frames, a bolster mounted therein, and instrumentalities for supporting the bolster and forming a horizontally-yielding connection between it and the truck or gear frames.
It relates, further and particularly to the means for yieldingly supporting the bolster or similar element in the truck-frames and to the construction of the bolster and the integral frictionmechanism with which it is provided for cooperating with the yielding bolster-supporting mechanism of the truck in providing the desired yielding cushioning resistance to the movements of the bolster and vehicle-body resting thereon in all substantially horizontal and downward directions.
The principal object of my invention is to provide a simple, economical, and efficient bolster and truck mechanism for vehicles.
A further object is to provide a bolster having friction mechanism arranged at each end thereof adapted to permit and provide a yielding cushioning resistance to the motion of the bolster in all substantially horizontal or down-ward directions. 7
A further object is to "provide a vehicletruck having a bolster mounted therein adapted to move in any direction with relation thereto and support the vehicle-body, and means for yieldingly resisting or cushioning and positively limiting the movement of the bolsterin all substantially longitudinal,transverse, and downward directions.
- A further object is to provide abolster having integral friction mechanism at each end thereof adapted to frictionally engage cooperating friction mechanism in the truck and provide, in connection therewith, a cushioning resistance to the movements of the bolof bolts 9.
ster in all substantially horizontal or downward directions.
Other and further objects of the invention will appear from an examination of the drawings and the following description and claims.
The invention consists in the features, combinations, and details of construction hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a side elevation, partly in section, of a car bolster and truck constructed in accordance with my improvements; Fig. 2, an enlarged sectional plan view of one end of the bolster and a portion-of the side frame of the cartruck, taken on line 2 of Fig. 1 looking in the direction of the arrow; Fig. 3, an enlarged sectional elevation of the side frame of the truck, showing one of the frictionblocks mounted therein, taken on line 3 of Fig. 1 looking in the direction of thearrow; Fig. 4:, a plan view of one end of my'improved bolster; Fig. 5, a plan view of a pair of sliding friction-blocks hereinafter described; Fig. 6, a side elevation of one end of my improved bolster, and'Fig. 7 an end elevation of one of the sliding friction-blocks shown in Fig. 5.v
In constructing a vehicle bolster and truck in accordance with my improvements I provide a truck-frame consisting of side frames (1, which, as shown, comprise an upper bar 1), lower and intermediate truss-bars c and d, bolster-columns c and f, mounted in such side frames and connected thereto by means The bolstercolumns are provided with downwardly-extending flanges g and upwardlyextending flanges h for engaging the bars of' the si de frame and holding the bolster-columns firmly in place, all of which portions of the side frames may be made inoneintegral casting,if desired. Apairofthese side frames and connections constitute what I term the truck-frame and may be joined together in any desired and well-known'mannor, as by means of cross-ties, (not shown, and are mounted upon journals (not shown) of the truck-wheels r; in suitable bearings in the boxes j in any ordinary or well-known manner.
A bolster 7c is provided and mounted in the a substantially horizontal direction when it reaches the truck, thus economizing the space above, beneath, and endwise of the bolster. To accomplish these objects, the bolster is provided at each end with preferably integral transverse supporting friction angular tongues Z, extending downwardly and inwardly at an angle beneath the ends of the bolster, so as to form a wedge-shaped base therefor. These friction-tongues areprovided with side surfaces m and n, extending downwardly and inwardly at an angle to each other.
Grooved friction-blocks and p are provided and movably mounted in the side frames of the truck, so as to slide horizontally therein when the bolster moves in any sub- I t V ...t. A

columns. These grooved sliding blocks are provided with upper grooved friction surfaces or ways u, extending downwardly and toward'the inner ends of such blocks at an angle corresponding to and in frictional engagement with the friction-surfaces of the bolster-supporting tongues. Spiral springs U are mounted between the sliding blocks and the truck-frames in pockets to in the ends of the sliding blocks and pockets 1 in the side frames or bolster-columns.
From the foregoing it will be readily seen that the friction-tonguesof the bolster rest upon the sliding friction-blocks in frictional engagement with the inclined ways orgrooves thereof, and that the spiral springs provide a yielding cushioning resistance to the movement of the bolster in all substantially hori-. zontal or downward directions, also that the side surfaces of the sliding friction-blocks and side surfaces of the friction-tongues being in frictional engagement form a yielding fric tional resistance to the end thrusts of the bolster, as well as to its movements transversely or downwardly.
To permit the desired limited transverse movements of the bolster, its sides 2 are arranged a sufiicient distance from the inner walls 3 of the bolster-columns or side frames to allow the desired play, and in order to limitits end thrusts the bolster is provided with upwardly-projecting tongues 4 and 5, To pre- It is also de-.
