| Abstract:
This invention relates to certain improvements in steering apparatus adapted for various uses, but more particularly for use with that class of machinery known as traction engines, which are adapted for hauling and also for motive power to be applied to other machines, an example of this kind of engine being given in my other pending application for Letters Patent on improvements in traction engines, filed November 6, 1890, Serial No. 370,497.
The object of the invention is to provide a steering mechanism capable of efficient and prompt action, yet simple in construction and inexpensive in the arrangement and application of its various parts.
Claims:
1. In a traction engine, the combination of the boiler, the forwardly-extending frames attached thereto, the axle journaled in said frames, the front wheel mounted on the axle by a gimbal bearing, the yoke connected to the wheel hub, the bow-frame on which the yoke is pivotally supported, said bow-frame being supported on the aforesaid axle, and a hydraulic piston whose piston-rod is connected to the bow-frame and also to the yoke, substantially as described.
2. In a traction engine, the combination of the boiler, the forwardly-extending frames attached thereto, the axle journaled in said frames, the front wheel mounted on the axle by a gimbal bearing, the yoke connected to the wheel hub, the bow-frame on which the yoke is pivotally supported, said bow-frame being supported on the axle, the hydraulic steering apparatus consisting of the hydraulic cylinder, its governing valve, the piston and piston-rod which is connected to the bow-frame and also to the yoke, and the connections whereby the attendant controls said valves, substantially as described.
3. Ina traction engine, the combination of the boiler, a frame at the forward end thereof, the axle journaled in said frame, the front wheel mounted on the axle by a gimbal bearing, said wheel consisting of the shell-like hub, a rim, spokes fastened to the rim and to the hub, the interior bosses on the hub receiving the pins that connect the hub to the rings surrounding the axle and the pivot passing through the axle and said ring, the yoke connected to the hub, the bow-frame on which the yoke is pivotally supported, said bow-frame being supported on the aforesaid axle, and the hydraulic steering apparatus consisting of the hydraulic cylinder, its governing valve, its piston and piston-rod which is connected to the bow-frame and to the yoke, and connections whereby the attendant controls said valve, substantially as described.
4. In a traction engine, the combination of the boiler, the axle journaled in a frame at the forward end thereof, the front bearing and steering wheel mounted on the axle by a universal joint, the yoke connected to the hub of said wheel, the bow-frame on which the yoke is pivotally supported, said bow-frame being journaled on the aforesaid axle, the hydraulic steering apparatus consisting of the hydraulic cylinder, its governing valve, a piston and piston-rod which is connected to the bow-frame and also to the yoke, and connections whereby the attendant controls said valve, which consist of a valve-rod a vertical guide shaft, the link extending therefrom to the crank which operates an eccentric pin for moving a lever, and the valve-rod, said lever having no fixed fulcrum but supported by a crank in the end of the shaft operated by c0nnection with the hydraulic piston-rod, substantially as described.
5. In a traction engine, the combination of the boiler, the forwardly-extending frames attached thereto, the axle journaled in said frames, the front wheel mounted on the axle by a gimbal bearing, said wheel consisting of the shell-like hub, a rim, spokes fastened to the rim and to the hub, the interior bosses on the hub receiving the pins that connect the hub to the rings surrounding the axle and the pivot passing through the axle and said ring, and the hydraulic piston connected to the Wheel in such a manner as to move it in a horizontal plane and thus direct the course in which the engine is to move, substantially as described.
