SLEIGH.

Application filed September 8, 1916.

T 0 all whom-it may concern:

Be it known that 1, Gimme L. SHERIDAN, a citizen of the 'United States, residing at Grygla', in the county of Marshalland State of Minnesota, have invented certain new and useful Improvements in Sleighs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to motor sleighs, and the primary object of the invention is to provide a sleigh which is particularly adapted for being propelled by an internal combustion engine or other suitable prime mover, which sleigh structure includes a drive shaft having a plurality of levers pivotally mounted thereon and extending longitudinally of the sleigh structure, the rear ends of which levers have an axle rotatably supported thereby upon which are mounted propelling wheels and means to operatively connect the axle to the propelling shaft of the sleigh. i I

A further object of this invention is to provide means including a plurality of springs, and means for tensionmg the springs, which are connected to the forward ends of saidlevers, for holding the propelling wheels for yieldable engagement with the surface over which the sleigh is travelmg. y

With the foregoing and other ob ects in View this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had tothe accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and inwhichz-Z- Figure l is a top plan view of the improved motor sleigh. Fig. 2 is a side elevation of the sleigh Fig.3 is a fragmentary vertical section through the rear portion of the sle1gh. 1; Fig; 4 i cross sectional view, through oneg'of'the propellingwh'eels of the sleigh! Fig. 5 is adetail-*view bf one of the groi ters or spurs which-are" attache'd tothe eriphcry oftlie'propellirigfwheelrand I ilii g'. dis a view-of amodified form of Specification of Letters Patent.

the grouterspr spurs which are attached to l the peripheries of the propelling wheels.

Referring more particularly to the drawings, 1 designates the main supporting structure of up motor sleigh which has rear runners 2 supported thereby. The front ends of the runners are connected to the supporting frame 1 by means of flexible members such as chains or the like indicated at 3, which act as safety chains.

The rear runners 2 have a bracket structure 2 attached thereto, the upper end of which bracket structure is pivotally connect.- ed by means of a bolt 2 to a bracing structure generically indicated by the numeral 2.

The bracing structure 2 includes a vertical brace 2 and a side vertical brace 2 and an angled side brace 2 The angled brace 2 and the vertical side brace 2 have depending ears 2 through which the bolts 2 extend as clearly shown in Fig. 4 of the drawings. The center brace 2 is connected to the side rails of the supporting frame 1 in any suitable manner as illustratedat 2 and the lower end of the center brace 2 is positioned between depending ears 2 formed upon the horizontal portions of the side braces 2 and 2. A cross brace 2 is mounted upon the upper end of the braces 2, 2 and 2 and it extends transversely across the rear end of the frame 1 of the sleigh. A pivotal connection between the brackets 2 and the bracing structure 2 permits therear runners 2 to rock. y

' A power shaft 5 is rotatably supported by the; supporting structure 1 and it may be operatively connected through the medium of bevel gears as indicated at 6 to any suitable type of prime mover, such as an internal combustion engine or the like.

Levers 7 are pivotally mounted upon the power shaft 5 and have their rear ends bifurcated as shown at 8. The bifurcated ends 8 .of the levers 7 rota-tably support stub axles a rate V shaft 21 in lieu of the lever 23, without dedrawings. In Fig. 6, the blade of the routers 11 is pointed, so into the ice or snow is traveling, while in the blade 11 has its indicated at 11" ditions,.than those for which the blade 11 is designed. Sprockets 12 are mounted upon the stub shaft 9 and sprocket chains 13 travel about the sprockets 12 and about sprockets 14 which shaft 5.

The forward ends of the lever, 7 curve upwardly as shown at 15,'and t ey have safety chains 15 attached thereto. Springs 16 are also connected to the curved ends of the levers 7 and these springs are eccentrically connected to mounted upon a shaft 21. If it is so desired, the springs 16 may be connected to the shaft by a chain or cable, without departing from the spirit of this invention. The shaft 21 is supported by suitable bearings and it has as to securely bite over which the sleigh Fig. 7 of the drawings, outer edge straight, as

its ends. A hand lever ztzis pivotaily mounted upon the shaft L and, it has a pawl 2-1 pii otally connected thereto which is adapted for coaction with the peripheral teeth of the ratchet 22 for rotating a shaft 21 and the drum 20 for regulating the ten' sion of the springs 16 for iii-messing or decreasing the spring tension on the levers 7 and consequently on the drive or propollin wheels 10, as desired. If it is so desire a hand wheel may be mounted upon the parting from the spirit of this invention.

The springs lfi are provided so that the proper tension will be administered to the leversfor causingthe drive wheels to raise or lower asthcy pass over uneven places in a road, and for continually keeping the necessary spring tension on the lev rie hold the driie wheels in engagement with the road bed to give the necessary or required rip to propel the sleigh.

Guar s 10 are attached tothe rims 10 of the propelling wheels 10, :ind extend ,inwardly toward the hubs 10. The guards 10 are substantially V-shaped in cross section and are attached to the spokes by rivets of analogous fastening devices, as shown in Fig. 5 of thc drawings.

From the foregoing description taken in connection with the accompanying drawings the advantages of construction and of the method of operation of the improved sleigh will be readily apparent to those skilled 111 for use under dill'erent con- 7 are mounted upon the.
