CAR-TRUCK.

SPECIFICATION forming part of Letters Patent No. 516,993, dated March 20,1894.

Application filed October 23,1893. Serial No. 488,943. (No model.)

To all whom itmay concern.-

Be it known that I, MORSE B. SCHAFFER, of the city of St. Louis, Missouri, have invented an Improvement in Oar-Trucks, of which the following is a full, clear, and exact descripion. The improvement relates to the spring-seats and columns of the truck. As heretofore constructed the springs of a car-truck have usually been supported upon a spring-plank that extends across the truck to connect with the arch and pedestal bars at each side of the truck, and the bolster guide bars'or columns have been parts separate from the sprin g-seats and attached to the spring plank, and notched at the top and bottom ends to receive the arch-bars. In the present construction the spring-plank is omitted and, at each end of the bolster, a united spring-seat and bolstercolumns are employed, and the construction is rendered more complete by means of crossties that extend from one side to the other of the truck, all substantially as is hereinafter set forth and claimed, aided by the annexed drawings, making part of this specification, in which- Figure 1 is a side view of the combination spring seat and columns used at each end of the bolster; Fig. 2 an end elevation of the same; Fig. 3 a View from the point of view of Fig. 1 and including the bolster, the bolster springs, and the associated frame-work; Fig. 4 a vertical section on the line 4-4. of Fig. 3; Fig. 5 a horizontal section on the line 5-5 of Fig. 4; Fig. 6 avertical section on the line l-4 of Fig. 3 showing the entire bolster and the more immediately associated parts; and Fig. 7 a plan of the parts of Fig. 6, a portion of the bolster being broken away, the arch-bar being femoved, and the arch-bar bolts being in sec- 1on. The same letters of reference denote the same parts.

A represents one form of bolster to which the improvement under consideration is adaptable. B B represent the bolster springs, O the arch-bar, D the inverted arch-bar, E the pedestal tie-bar, and F F the arch-bar bolts. All these parts are constructed and combined in the usual manner saving as modified by the embodiment therein of the present improvement.

erably by means of the rivet h.

partsA B O D F G are combined substantially I as shown.

H H represent ties which serve to unite the two sides of the truck. The preferable mode of connecting them with the truck sides is shown. The bars are perforated to receive the bolts F and are connected therewith between the bars D and E, and the ties are crossed and united midway in their length and prefeach end thereof, is folded, and the bolt F passes through the main part of the bar and also the fold h, and the fold has a flange m,

which when the parts are assembled, bears against the inverted arch-bar or some other part of the side of the truck. Any other suitable mode of uniting the two sides of the truck will answer, although I prefer the method shown.

The omission from the truck of a springplank, or at least of the middle portion thereof, enables the springs, and their immediate support at each side of the truck to act more independently than if a spring-plank were employed. The spring-seat at either end of the bolster can accommodate itself better to the springs resting thereon than if it were a portion of a continuous spring-plank. Each spring-seat can be more readily strengthened vertically (for instance,it may have the flanges or ribs g g and the brackets g 9 than if it were an integral portion of a spring plank. The combination of the bolster columns with the spring-seat in a single integral part as here shown is also desirable not only in that it diminishes the number of separate parts employed in a car-truck but also in that thereby a stronger and more satisfactory construction is obtained. Furthermore, the improvement enables the use of a deeper bolster than if the spring seats were extended to meet each other as in the form of a spring plank.

Each tie, at

seats, and the two pairs of bolster-columns, said seats and said pairs being respectively integral, but the combined seat and columns at one side of the truck having no direct connection with the combined seat and columns at the oppositeside of the truck, substantially as described.
