SPECIFICATION forming part of Letters Patent No. 492,230, dated February 21, 1893. Application filed October 24, 1892, Serial No. 449,841, (No model.) To all whom it may concern. forms A, are projected, to furnish means for Be it known that I, BENNETT PRICE, of entering the car, and for the accommodation Brooklyn, in the county of Kings and State of of the driver or motor man, common brake New York, have invented new and useful Im rigging E, being furnished for the control of 55 provements in Supplementary Trucks for the vehicle when it is to be stopped. Street-Railway Cars, of which the following is The improvement consists essentially, in a full, clear, and exact description. the provision of two supplementary trucks, Railway lines occupying streets of a town one for each end of the car, each truck com or city, are at times blocked by the stretch prising a single transverse axle, having a pair O ing of lines of hose across their tracks during of wheels, and attachments therefor, that by a fire, or from the disablement of a car due manipulation from the car platforms, will ele to a broken wheel or axle on it. Such im vate the car body and its main wheels and pediments to regular travel are sources of an axles, throwing the weight on the supplemen noyance to the public as well as a loss of val tary trucks, that are located a proper distance 65 15 luable time. from the main car wheels toward the end The object of my invention is, to provide platforms. efficient means for the transference of a street The supplementary trucks being alike, a railway car across a line of fire hose that is description of one will answer for both, and stretched transversely of the track; and also as shown, they consist essentially of a trans to obviate the protracted stoppage of a rail verse axle F, on which the flanged wheels F, Way Car On account of the accidental break are secured near each end leaving journal age of one of its wheels or an axle. ends projecting beyond said wheels. To this end my invention consists in cer. The boxes a, which are designed to loosely tain features of construction, and combina engage with the journals of the axle F, are 75 25 tions of parts, as is hereinafter described and secured upon the lower ends of the coarsely claimed. threaded screw rods b, that are screw cut Reference is to be had to the accompanying throughout their length, and which project drawingsforming a part of this specification, upwardly through the platform A', and into in Which similar letters of reference indicate the guide boxes b', which latter are attached corresponding parts in all the figures. | to the end walls of the car body A, vertically Figure 1 is a side view of a street railway and near its side edges.

A bracket block d, is pro raise the main car wheels from the track; vided for each bevel wheel c, and has a cy Fig. 4 is an enlarged reverse plan view of an lindric Socket or recess formed in it from be end portion of a street railway car, and a part low upwardly, of such dimensions as will per of the improvement on it; and Fig. 5 is a mit the cylindrical hub of the bevel gear broken front end view of a car, and the novel wheel c, to fit loosely in it and seat upon the attachments on it, adjusted to elevate the car top wall of the recess, as indicated in Fig. 5. body and its main wheels from the track rails. The bracket blocks d, are suitably flanged and The car body A, is of any approved con adapted for a bolted attachment on the lower 95 45 struction, and may be adapted for electrical sides of the longitudinal side timbers of the propulsion, or be drawn by horses on a rail car bottom frame, or lower surface of the plat way track B, the ordinary main wheels C, and form near the side edges, as may be preferred, transverse spaced and parallel axles D, being so as to permit the screw rods b, to project Evided to afford rolling support for the car vertically through holes in the platform, and Od so ody. penetrate the guide boxes b', as before men At each end of the carbody the usual plat tioned. There is a hub portion projected 2 492,230 from the lower face of each of the bevel gear at a convenient distance from the platform, wheels c, to enter and loosely fit an apertured. for manipulation. A spring pressed vibrat cap plate d', that is secured upon the lower able pawi p shown in Fig.1, is furnished for o surface of the bracket block it engages, there each wheel o, and as usual is adapted to Slic by retaining the gear wheels in position on cessively engage with the teeth of the ratchet the car body below the platform and free to wheel, when the lever O is vibrated, and Com rotate in the bracket blocks.
