JOEL MOSIMAN, OF FALLS CITY, NEBRASKA.

TRACTION-ENGINE.

SPECIFICATION forming part of Letters Patent No. 333,658, dated January 5, 1886.

Application filed November 2, 1885.

To all whom it may concern:

Be it known that I, JOEL MosIMAN, of Falls City, in the county of Richardson and State-of Nebraska, have invented certain new and useful Improvementsin Traction-Engines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to theletters of reference marked thereon, which form part of this specification.

My, invention relates to traction-engines; and its objects are, first, to augment the effective action of applied power; second, to decrease the strain on the rear drivers; third, to secure a uniform wear of the parts; fourth, to provide for the passage of obstructions without detriment to thedrivers or the mechanism; fifth, to so distribute the imparted energy upon the wheels as shall cause them to operate synchronously and actuate equally the burden; sixth, to provide for the variable exigencies to which the engine may be called by simple media; and, seventh, to attain these ends with structural simplicity and economy of operation. I accomplish these aims by the mechanism illustrated in the accompanying drawings, in which--- Figure l is a side elevation of a tractionengine embodying myimprovements, showing their relative location and the manner of their coactionineffectingthedesiredpurposes. Fig. 2 is a plan view of the actuating mechanism; and Fig. 3 is a detail view, partly in section, of the bearing J, which serves to hold the axle of the front drivers.

The same designationsindicate corresponding parts in the several views.

The power-piston incident to engines of this character actuates the shaft on which the Wheels N O are concentrically mounted. The former is a geared pinion, which revolves the gear-wheel M, while the latter serves as a flywheel. The wheel M imparts its rotation to the pinion B, on whose shaft 0 the bevelwheel A is also mounted. The pinion B meshes with the pinion P on shaft P of the rear driver, thus operating the same. The bevel-wheel A in turn actuates the shaft E by means of the pinion D. This shaft is held in bearings F, and its terminal pinion G transmits the received motion to the crown-wheel Serial No. 181,660. (No model.)

H, which may be of different forms to secure variable effects,and is centrally secured to the shaft I, that depends by a universal joint, J, from the engine. A curved rod, L, secured by nut L, steadies the base of this shaft, and at its lower terminus a bearing. J, is secured, to permit the revolutions of the shaft K by reason of the wheel K (on said shaft) and the wheel H being meshed. Chains S S, having suitable hooks, R, to which draft may be applied, are provided with terminal universal links H Rsecured near the respective ends of the front axle, that serve to effect the diversion of the same, and so guide the machine. It will be understood that the aim of this construction is to cause the front wheels to assist in driving the engine,and thus the power and strain are so equally distributed that the wheels operate at the same time and wear evenly, as well as preventing the jarring motion incident to engines moved solely by rear drivers. It is apparent,also,that other mechanical media might be substituted for those illustrated without materially affecting the results secured. Such modifications I deem within the scope of my invention.

Its operation is as follows: The motive power effects the rotation of wheel 0, on whose shaft is the pinion N, which transmits the energy to pinion B by means of gear-wheel M meshing with both. The motion of the pinion B as well causes the revolution of the rear drivers (by meansof the geared pinion P) as effects the actuation of the front drivers, (because the bevel-wheel A imparts the motion of the shaft G to the shaft E by the pinion D, and it is thence taken up by the crownwheel H, which is in gear with the pinion G.) The crownwheel H in turn rotates the geanwheel K, which is rigidly secured on the shaft K. Thus the steam-generator is applied mediately as well to the forward wheels as the rear ones, and the locomotion is correspondingly facilitated.

Having thus fully described my improvements, what I claim, and desire to secure by Letters Patent of the United States, is-

1. The concentric gear-wheels N O on the same shaft,operated as described, in combination with the gear-wheels M B 1? A, the shaft E, having terminal pinions D G, the toothed wheels H K, and the shaft K, whereby the In testimony that I claim the foregoing as front and rear drivers are simultaneously immy own I affix my signature in presence of pelled. two witnesses.

2. The concentric gear-whee1sN O, mounted 5 on the same shaft, operated as described, in JOEL MOSIMAN.

combination with the gear-wheels M B P A,

the shaft E, having terminal pinions D G, the \Vitnesses: toothed wheels H K, the shaft K, and the A. MINNICK, universal joint J, depending from the engine, E. D. STOUGHTON.

IO the whole eoacting for the purpose set forth.
