flu/entanform a further function'in preventing the lifting of the car-body when the safety or track brake is used, as will be explained later.

The two-wheel truck is built u pon substantially the same constructive principles.

before described. In this dase,'however, I'

prefer to employ but one set of guard-wheels c for the truck. These instead of being carried on extensions of the axles c or studs projecting from the axle-block b are carried on a central crossbar e, secured across the frame I), as shown in Fig. 4. The guide-framed and guide-rollers d are in this case unnecessary, as the second bearing-wheel performs their functions.

. To control thespeed or effect: stoppage the car, I prefer to employ a track-brake of the following construction: Two "bell-crank levers f are pivoted, preferably, upon the axle c at opposite sides, respectively, of the main bearing-wheel C. At their lower terminals they are secured to a metallic shoe 8,

adapted to bear upon the track. The upper terminals of the levers are connected by rods 9 witha hand-lever L, pivoted to acleat m, attached to the rear of the frame-b. There is thus formeda drag, in which the shoe 8 is hung from the axle of the bearing-wheel and operated by the hand-lever L. It will be seen that the effective limit of the shoe fric- -tion would under ordinary circumstances be the weight of the car, but in this case the guard-wheels prevent lifting of the car, and the shoe may therefore be brought to bear against the track,with any force desired.

The brake may be made double,as indicated The annular wheel-frame is lengthened to accomby dotted lines in Fig. 5, so as to operatein either direction. a

I may employ both single and double wheel trucks together in trains of two or more cars, as indicated in Fig. 8. I

I do not claim in this application the brake mech'l'tirism herein shown and described, as the same forms the subject-matter of a separate application filed by me on the 21st day of February, I901, Serial No. 48,223.

I claim as my invention and desire to secure by Letters Patent of the United States- 1. A car-wheel truck embodying an annular frame, adapted to a swiveling or pivotal aoiion in relation to the car-body, one or more double-flanged bearing-wheels journaled diametrically in the same, and fixe'd studs extending outwardly at opposite sides carrying guard-wheels adapted to run beneath guardrails, substantially as set forth.

2. A car-wheel truck embodying incombination, first, a frame adapted to;,a swiveling or meted action in relation to the? car-body; second, a bearing-wheel journaled diametrically in said frame, adapted to support the load upon the running-track; third, wheels carried at opposite sides of the truck, and adapted to run beneath guard-rails; 'fourth, a rigid extension ofthe truck-frame; and, fifth, guidewheels carried upon said extension and adapted to bear laterallyagainst the guard-rails.

3. In a single-rail railway system, a truck embodying anannular frame, two bearing- Wheels journaled within and across the same at opposite ends, and a central bar secured to the frame centrally between and parallel with the wheel axles, and carrying the guardwheels at its extremities, substantially as set forth. l

In testimony whereof I have hereunto set .1
