SPECIFICATION forming part of Letters Patent N o. 721,625, dated February 24, 1903. Application led September 12, 1901. Serial No. 75,186. (No model.)
To a/ZZ whom it may concern,.-
, Beit known that I, SAMUELMVAUCLAIN, a citizen of the United States, residingin Philadelphia, Pennsylvania, haveinvented certain Improvements in Trucks, of which the following is a specication. The object of my invention is to improve the construction of railway-car trucks, especially those used in connection with elecxo trically-propelled cars.
In the accompanying drawings, Figure lis a side view of my improved truck. Fig'. 2 is a transverse sectional view on the line 2 2,
Fig. l. Fig. 3 is a plan view of one-half the t5 truck with the axles omitted. Y.
1 A is the truck-frame, which consists of two side members A and cross members a. The side members are made of either cast or wrought steel and are shaped as Aclearly shown zo in Fig. 1. These side members are recessed at a' c for the reception of the boxes B for the journals of the axles C,on which aremounted the Wheels C.
D is a transverse frame extending from one side member of the truck-frame to the other.
The said frame has extensionsd d, with depending portions entering cavities a2 in each of the side members A'. Within each cavity is a spring E, which serves to support the 3o transverse frame D on the truck-frame A.
Suspended from the transverse frame D, in the present instance by links ff, is a springplank F, and mounted above .the plank F is a bolster G, carrying the center plate H, on 3 5 which the car-body rests. This bolster is guided in the transverse frame Dand can be made in any form desired, in the present in-A stance being mounted upon springs I I, carried by the spring-plank F, so that there are 4o two sets of springs E and I between the truckframe A and the bolster G, thus making the car ride much steadier than if but a single set of springs were used between the bolster and the suspension-frame or if additional springs were mounted between the axle-boxes B and the truck-frame A. Furthermore, this arrangement'simpliies the construction of the truck, and the springs E are protected, being mounted in the cavities in the side frames A.
I claim` as my invention- 5o l. The combination in a car-truck, of a frame having side members, each made of a single casting recessed near each end, axleboxes in said recesses, two circular cavities formed in the upper portion of each side member near the'center, springs therein, and a 'transverse frame having depending portions extending into the said circular cavities' and supported by said springs, substantially as described. i 6o 2. The combination in acar-truck, of a truck-frame having side members, axle-boxes mounted thereon, two cavities in the upper portion of each side member near the center thereof, a transverse frame having projections directly above the cavities and having portions entering the cavities, coiled springs within each cavity for supporting the transverse frame, a spring-plank, links connecting the plank with the transverse frame, springs 7o on the plank, and a bolster mounted on said springs and guided by the Atransverse frame, substantially as described/ In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
