Manufactured by Best Mfg. Co. - San Leandro, Alameda County CA

Abstract: My invention relates to that class of locomotive-engines which are designed to travel upon roadways and other surfaces without tracks, and which are also adapted to haul loads and to operate as stationary engines for running agricultural and other machines. The objects of my invention are, first, to increase the power and speed of the engine with- oat increasing its weight or cost, and to render the machine capable of traveling easily over hilly or uneven surfaces, and also over soft ground; second, to render the steering action simple and prompt in operation; third, to perfectly balance the boiler upon the supporting-frame, so as to avoid all strain upon the frame and engine while the machine is traveling over uneven surfaces; fourth, to so mount the engine upon the frame-work that it may be readily connected to and removed from said frame; fifth, to apply the motive power directly to the traction-w heels, and to allow for variations in speed of the wheels while the machine is turning around; sixth, to permit of ready variations in tile speed of the ma- chine, and to entirely disconnect tile propelling-gear, so that the engine may operate as a stationary engine, and, last, to simplify and strengthen the machine as a whole. Claim: In a traction-engine, the combination of the main frame having the semicircular- rear portion, the boiler secured thereto, and the curved or- U-shaped axle passed around the rear side of the boiler and flexibly connected at its spindles to the frame, with the hangers engaging beneath the bottom of the boiler with their lower hooked ends, and slidingly connected to the axle at their upper ends, and~ the springs cushioning the vertical play of these hangers.

Manufactured by Best Manufacturing Co. - San Leandro, Alameda County CA

Abstract: It is the object of my invention to provide an elastic support for the boiler, engine, and supporting-frame of a traction-engine, and such connection between the frame and the bearing-wheels and axle thereof that the movement of the supported parts upon the springs will not interfere with the proper meshing of the gears by which power is transmitted from the engine to the gears upon the main bearing-wheel whereby the latter are revolved. Claim: The combination in a traction-engine of the frame; the bearing-wheels; the axle; transverse plates forming a channel within which the axle is movable; yokes suspended directly from the axle, and plates through which the ends of the yoke pass; and springs disposed between the last-named plates; said first-named plates bearing directly upon the uppermost of the last-named plates.

The adjusting worm of an adjustable open end wrench has slots into which a spring-tensioned "U" shaped latch can enter, forming an adjustment lock. An analogous form employing a ribbed spring for notches in the adjusting nuts of "monkey wrench" and "Stillson" type pipe wrenches appears in parallel patent 1,367,407.
