CHARLES WHITNEY DENNIS, OF AUGUSTA, MAINE.

AUTOSLEIGH.

Specification of Letters Patent.

Patented Nov. 24, 1908.

Application filed April 27. 1908. Serial No. 429,558.

To all whom it may concern:

- Be it known that I, CHARLES \Ynrrunr 1)!)NKIS, a citizen of the United States, rcsiding at Augusta, in the county of Keane lain new and useful Improvements in Autosleighs, of which the following is a specification, reference being had therein to companying drawings.

My present invention relates to an improved autosleigh, and has special reference to a sleigh adapted to be propelled by any fori'n of power, such as explosive engines, steam or electricity, the main feature residing in the fact of a peculiarly constructed propelling machine which will not allow the machine to sink deeply into the snow, all of which will presently appear.

To clearly illustrate my invention, attention is invited to the accompanying drawings, in which Figure 1 is a side elevation of the comlete antosleigh. Fig. 2 is a top plan view of the steering or forward runners. Fig. 3 is an enlarged detail view of one portion of the steering mechanism. Fig. 4 is a cross section thereof. F ig. 5 is a top plan view of the propelling truck and runners, the body being removed. Fig. 6 is an enlarged detail plan view of the steel propelling runner. Fig. 7 is an elevation of one of the propelling axles and drums, and Fig. 8 IS a cross section on line ww of Fig. 7.

Referring to the drawings :--The numeral 1 designates the platform the forward power carrying casing 2, an the rear body The forward part of the platform is pivotally connected at 4, to the steering runner frame 5, which carries the two runners 6, which, are secured to ether by means of the braces 7 In or er to cushionly support the power casing, I employ the two elli tical springs 8. n order to steer or turn t e. runners 6, I employ the rod 8', which is provided with the angularly circular worms or segments 10,

set senn which are always in engagement with the long pinion or cog 11., carried upon the lower end of the steering post 12, whose wheel 13, gives full control to the steering of the autosleigh.

The rear body 3, is supported by means of the springs 14, u on the truck-frame 15 which consists of the upper and lower metal plates 16, supported and braced apart by means of the angle-irons 17, to form the rethe acor support, for

l l l l ceptaclcs at the ends for the journal boxes 1H. m \\'llll'll are mounted the front and rear axles l9 and 20. respectively. (arried upon each axle is a pair of pulleys or drums 21. t i bee and btate of Maine, have invented cerl l l steering true t .ed' below the front of said platform,

cuch of which consists of the rims 22, and the series of flat portions 23, which provide the angles 2-1. Mounted upon these drums, that is pairing, the right forward drum with the right rear drum, and the left forward drum and left rear drum. is what I term the movable runners or tires 25. one to each pair. 'lhese runners or tires are made in sections 26. the inner surface 2(5', of which is of the same width as each flat portion or surface 23 of the drums. and as each section 26, is hingedly connected to the adjoining one by means of the hinge 27, the runners will closely adhere to the contour of the drums and be moved in the proper direction by the movement of the drums. Upon the outer surface of the movable runners and to the sections thereof, I secure the ribs or gripping rods 28, which extend preferably the full width of the runner, and are tri-angular in cross-section. By this means it will be seen that the width of the two movable runners, prevent the rear portion of the autoslcigh from sinking into the snow, acting as a snow shoe, and as the front axle is revolved, the movable runners are operated so that their gripping rods will rip the snow and thus propel the autosleig 1, and movable runners imparting a rotary motion 0 the rear axle, acting as a belting.

Upon theforward axle, I mount a gear 29, which is operably geared to the gear 30, carried upon the shaft 31, which extends forwardly and is connected to the motive power in any suitable clutch (not shown).

From the foregoin description taken in connection with the drawings, it is evident that I provide a practical antosleigh, asI provide a platform carryin the motive power and o erators seat and rear body, a

mounted upon stationary runners, and a propelling truck having its movable propelling runners operably connected with the motive power, and being so climstructed as at the same time they propel the a autosleigh,

sinking into 1m air the at I 0 arm,

1. In an autosleigh, the combination, of a:

platform, a steering runner pivotally mpun motive a front axle journaled in the forward boxes of the truck frames, a r M axle ournaled 1n the remaining boxes, means for operably connecting the trout axle with the motive 1 power, two drums each having a central portion composed of a series of different angled lanes and corners and with projecting rims (eyed to each axle. said drums being separated by a central space upon each axle, two endless propelling belts paralleling each other and mounted upon their respective i drums of the front and rear axles, the front axle conveying motion to the rear axle through the medium of the belts, and each belt being made of a series of sections flexibly connected together to conform to the contour of the central portion of the drums and with exterior gripping ribs.

2. In an autosleigh, the combination of a l in presence of witnesses.

platform, a steering runner pivotally mounted below the front of said platform, motive power mounted upon the platform above the steering runner, a rack bar extending transversely of the runner, a steering mechanism l operably connected therewith and accessible the platform, 7 ournal boxes mounted in said truck frames, 1

in the rear of the motive power, springs carried below the rear portion of the platform, one upon each side, truck frames, one to each s )ring, connected with the spring to support t e p atform, journal boxes mounted in said truer frames, one in each end, a front axle journaled in the forward ones of each frame, a rear axle journaled in the rear ones of each frame, means for operably connectin the front axle with the motive power, two rums each having a central portion composed of a series of different angled lanes and corners 1 and with projecting rims eyed to each axle said drums being separated by a central space upon each axle, two endless ropellin belts paralleling each other an mounte upon their respective drums of the front and rear axles, the front axle conveying motion to the rear axle through the medium of the belts, and each belt being made of a series of sections flexibly connected together to conform to the contour of the central portion of the drums and with exterior gripping ribs.

In testimony whereof I afiix my signature CHARLES WHITNEY DENNIS.
