EMILY CAR-TRUCK.
SPECIFICATION formingpart of Letters Patent N o. 562,212, dated J une 16, 1896. Appleman mea February 15,1896. serrure. 579,429. (Nomaden) To @ZZ whom it may concern:
Be it known that I, WILLIAM H. BOYN'ITON,
of Morris Park, Queens county, New York, have invented an Improved Oar-Truck, of which the following is a specification.
This invention relates to a car-truck for that class of railways in which the car engages a single rail on top and also a single rail at the bottom.
The car is propelled by means of the trolley system, and the object of the invention is more particularly to so construct the truck that it is properly counterbalanced and that it occupies a minimum amount of room in a lateral and also in a vertical direction.
In the accompanying drawings, Figure 1 is a horizontal section of my improved car-truck on line l l, Fig. 2; Fig. 2, a vertical longitudinal section on line 2 2, Fig. l; and Fig. 3, a vertical transverse section on line 3 3, Fig. 2.
The letter a represents a horizontal frame provided at its front and rear with boxes d', in which arehung the axles b' of a pair of traction-wheels b. These wheels are placed centrally within the frame and in line with one another, so as to engage the single trackrail A. Centrally between the axles h there is hung in boxes d2 of frame a the powershaft c, that carries two electric motors c of ordinary or suitable construction.
These motors are preferably of the same weight and size and are secured to opposite ends of the shaft c, equidistant from its center, so that they counterbalance each other. Upon the shaft c are furthermore mounted a pair of gear-wheels c2, each one of which is interposed between and engages a pair of wheels b2, mounted upon the axles b. Thus it will be seen that the motion of the powershaft is transmitted to the axles in order to drive the same.
Upon the frame a is supported, by means of springs e', a second or upper frame e. This frame is provided with a central transverse beam c2, from which the king-bolt c3 projects upwardly. The car body (not shown) engages this king-bolt in the ordinary manner, and is provided with means for engaging the upper or overhead guide-rail of the track.
The main advantages connected with my truck are its compactness, both in a vertical and a lateral direction. Moreover, by mounting two motors upon the power-shaft, they serve to counterbalance each other, while at the same time they may be made so small as not to necessitate an undue elevation of the king-bolt.
1. A car-truck for a single-rail track, composed of a frame, a pair of axles hung therein and carrying single traction-wheels, a powershaft placed between the axles and gearing for connecting the power-shaft with the axles, substantially as specified.
2. A car-truck for a single-rail track, composed of a frame, a pair of axles hung therein and carrying single traction-wheels, a powershaft placed between the axles, electric counterbalancing-motors secured to opposite ends of the shaft, and gearing for connecting the shaft to the axles, substantially as specified.
3. A car-truck for a single-rail track, composed of a lower frame, a pair of axles hung therein and carrying single traction-wheels, a power-shaft placed between the axles and intergeared therewith, a pair of motors secured to opposite ends of the shaft, an upper frame spring-supported upon the lower frame, and a king-bolt projecting upwardly from the upper frame, substantially as specified.
