IMPROVEMET IN TRACTIONENGINES.

Specification forming part of Letters Patent N o. 173,498, dated February l5, 1876; reissue No. 7,736; dated June l2, 1877 application ledMay 23, 1877.

1b all whom it may concern:

'Be it known that I, Gnomes Rousse, of Mount Vernon, in the county of Knox .and State of Ohio, have invented certain new and useful Improvements in Traction-Englnes;

f and I do hereby declare that the following is a full, clear, and exact'description thereof, that will enable others skilled in the art to which it appertains to make and use the same, rel'- erence being had to. the accompanying draw ings, and to the letters of reference marked thereon, whichform a part of this specitication.

lMy invention relates to an improvement in traction-engines.

In the drawing, Figure 1 is a side elevation of so much of a tractiomengine as needed to illustrate my invention. ,the saule.

A is the boiler of the engine, and B is the driving-shaft, to which power is applied from the engine-cylinder. The boiler is supported at its rear by truckwheels F', and at its front by truck-wheels K. The truck-wheels F are mounted upon a shaft, D, which may be either continuous or divided-that is to say, each wheel may have its own axle, or one axle may serve for both. vIn either case, however, there is practically but one axle, which I shall term the rear axle, constitutingthe axis ol' revolu1 tion of the wheels F. The truck-wheels F' are rotated by means of gearwheels E, which have the rear axle as their axis, and mesh with pinions or cogwheels F lxed on a shaft, X, which I term the supplemental'shaft, revolving in suitable bearings or boxes o' b, carried by the boiler. The supplemental shaft derives its motion from the driving-shaft B through the intermediary of the shaft (J, which I shall term the connecting-shaft. This con'- neeting-shaft, supported insuitable bearings c o', engages at one end the driving-shaft and at the other end the supplemental shaft. The engagement is efected, in the present instance, by means of beveled gearing Bl U 0 D', as shown. I

When the wheels F and E are made and mounted on their axle separately, any suitable arrangement-such as the pawl and ratchet G G', applied the one to the gear E and the other to the truck-wheel lsv-will cause the truekwheels to be driven by the gear, and yet Fig. 2 is a plan ot'` admit of the independent movement or revolution ot the truck-wheels whenever this becomes necessary-as, for instance, in turning the machine w the right or left. In the presont ease the pawls and ratehets are in the housings of the wheels 'F' E, and these wheels revolve freely on their axle.

' H is a screw passing from the boiler down through the front truck or axle, answering not only as a king-bolt, but also as a lifting. jack, by means of the nut-wheel H', mounted on the screw between the boiler and the front axle or truck, and resting on the latter. By turning the nut-wheel in one direction or the other the front end of the boiler will be raised trom or lowered toward tbe front axle. When the boiler is so actuated it moves upon the rear axle as its axis., The pinions F ol' the supplemental shaft (which participates in this movement of the boiler) therefore move in the arc of a corresponding circle, and, consequently, preserve their engagement with the gears E.

I. is a tongue or pole for attachment of horses, oxen, &c., for the purpose not only of assisting in the draft, but likewise of steering or guiding the machine.

The feature ot adjusting the elevation of the front end of the boiler is for the purpose` of maintaining, as nearly as possible, the level position of the boiler in traveling upon an inclined road, so as to insure safety by having the crown-sheet and llnesat all`tixnes proper. ly covered with water.

lhe invention herein described is especial ly adapted to portable engines now so extensively used for farming purposes, and for sawing timber in variousplaces. lt has heretofore been found more or less dillcult, especially during inclement seasons, to convey the so-called portable engines from place to place. This invention is intended to obviate, to a great .extent at least, this diieulty and objection, and its character is such as to render it easily adaptable to portable engines already in use, and not provided with any power ot' self-locolnotion.

Haring described my invention, what I claim, and desire to secure by Letters P atent, ls-

1. The combination of the drivingehaft and the rear axle, having truck-wheels adapted to be looeelyor rigidly Been'red to it; with the supplemental shalt, provided with cog-wheels, gearing with wheels von the rear axle, and the intermedateconnecting-shaft, engaging at one end the driving-shaft and at the other end the supplemental shaft, as herein shown andl set forth. Y

2. In a traction-engine; eo as to be capable of upon its power-driven axle as'anaxis,- and means for so moving said boiler, in combination with a rotary supplemental shaft, which aboiler supported with wheels oscillatory movement.

derives its rotary m'ovement'from the drivingshalt of the engine, is carried byand pai-takes of the movement of the boiler, and ears on said aille, substantially as shown and eet forth.

In 'testimony that I claim the foregoing I' Y have hereunto "set my hand this, '21st day of.

May, 1877.-
