ICE-VEHICLE.

srncrmcnmon forming part of Letters Patent No. 734,552, dated a as, 1903.

Application filed March 1, 1202.

To all whom it may concern:

Be it known that I, ISAAC N. HENNESS, a citizen of the United States, residing at Ilwaco, in the county of Pacific and State of Washington, have invented certain new and useful Improvements in Ice-Vehicles, of which the fol-- lowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in vehicles designed to propel themselves and, if desired, of hauling other vehicles over the ice or snow.

The object of the invention is to provide a vehicle capable of traversing rough ice, deep snow, and slush, which I attain by the con struction and arrangement of parts hereinafter described, and illustrated in the accompanying drawings, wherein- Figure 1 is a plan view of a vehicle embodying my improvements. Fig. 2 is a central longitudinal vertical section of the same. Figs. 3 and 4 are respectively enlarged perspective views of a propeller-shoe and the steering-rudder.

Referring to the said drawings, the vehicleconsists of a water-tight body comprised of side plates at and a bottom plate b, bent upwardly to form ends I); suitable framing to provide structural strengthto the same, and longitudinal runners 0, extending throughout the body length and to some distance rearwardly thereof.

d'represents a steam-boiler and its attachments, and e arr-engine. 1

To the after end of the vehicle-body is journaled in boxes f a multiple crank-shaft g, which is rotated by a link belt h, passing around sprocket-wheels t' 9; upon the said. crank-shaft and the engine-shaft, respectively. To the several crank-pins of said shaft are pivotally connected push-bars it, having shoes Z, which engage with the ice or other supporting-surface. The said shoesl (see Fig. 3) are each formed of a plate curved near one end to form a ball m, upon which to slide in their forward travel, a flange m at the other end, and a hollow or cavity m therebetween.

Projecting forward of the vehicle-body is an extension-piece 0, folded back at its outer end to provide double bearings o for the post p of rudder p, which is vertically movable Serial No. 96,315. (No man.)

therein to compensate for the irregularities of the surface being traveled over. In order to exert a greater downward force or more them by a pin q, eccentric of the perimeter of the said forked end, and thus provide a fulcrum against the upper fold 0" of the piece 0 by raising the handle end of the tiller after the. rudder has been swung around to the proper steering-angle. with the rudder, are intended as supports for the rudder when in slush or soft snow.

To remove snow-drifts encountered in the path of the vehicle or in opening new roads,

I contemplate using, in combination with the 7c vehicle, a snow-shoveler which consists of a double-bladed shovel 2, mounted upon the extremity of a shaft 3 3, which is rotated from the engine by link belt 4, sprocket-wheels 5 5', and bevel-pinion 6 and gear-wheels 7 8.

The shaft .9 of sprocket-wheel 5 and pinion 6 is journaled in fixed boxes 10. The gear wheel 7 is mounted upon a vertical shaft 12, journaled in bracket-box l3, and seated thereon, so as to seat loosely about shaft 12,

is the hub of a swiveling frame 14, carrying the journal-boxes 14 of shaft 3. Positioned between the last-named boxes and splined to shaft 3.is a sleeve 15, upon which are fixed the bevel gear-wheels 8, adapted to mesh with 8 bevel-wheel 7 for rotating the said shaft in either direction. This is accomplished by means of a lever 11, fulcrumed at '11 to the swiveling frame and engaging with horns 11" of the said sleeve, whereby the latter may be o shifted so as to put either of the said Wheels 8 into or out of engagement. The shaft parts 3 3 are connected by a universal joint 20, so

as to deflect the same out of a right line in either. a vertical or horizontal, direction, the 5 outer part 3 being controlled by a lever 16, fulcrumed at 17 to the frame 14, which is inf termediate of the handle end 16' and its connection 16" With a sleeve-bearing 18, located in proximity with the rotatable shovel.

By means of the swivel mounting of frame 14 the shaft Smay be directed toward any angle with the axis of the vehicle, and uy means of the said universal joint onf' the Wings 19, integral 65 shaft the shaft may be swung vertically or horizontally. Consequently the shoveling or, more correctly, scraping may done anywhere within reach of the device with ease and despatch. The fact that the direction of rotation of the shovel may be reversed is of importance, inasmuch as the material to be handied can be moved from either side and in either transverse direction.

The operation of the vehicle-propelling device is extremely simple and is adapted to accomplish the purpose for which designednamely, the rapid propulsion of the vehicle over rough or hommocky ice or snow surfaces-an important element to its successful operation being the foot-piece or shoe Z, whereby the vehicle may be propelled upon either hard ice or soft snow or slush. Also, in the latter the Hat toboggan-like bottom of the vehicle-body supports the same against immersion therein.

Having thus described my invention, what I claim as new, and dcsi re to secure by Letters Patent, is

1. In an ice-vehicle, the combination with the body having a waterproof body portion, propelling push-bars, and a steering device;

of means to clear a path of snow or the like in advance of the vehicle, such meanscomprising revoluble blades fixedly mounted upon a swinging shaft projecting forward of the vehicle-body, devices whereby the said shaft can be rotated in opposite directions, substantially as described.

2. As a means of clearing the path in advance of an ice-vehicle, the bevel-pinion 6, shaft 9, bevel-wheel 7 mounted on a vertical shaft 12, a frame 14 swiveled on last-named shaft, another shaft 3 journaled in frame 14, a sleeve splined to shaft 3 and having a. bevel gearwheel fixedly mounted to its opposite ends, means to shift the said sleeve lengthwise upon shaft 3, a universal joint in shaft 3, a blade or blades2 mounted upon the outer extremity of shaft 3, and an outer sleeve-bearing 18 and lever 16, arranged and operating as herein shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

ISAAC N. HENNESS.
