Description

EQHN: HiV Mm Gli @EEN ETI ,shaft 10.
of the spring 28. These levers are fulcrumed on a rod 32 extending between and carried by the frames 26. Adjacent to the ,vdrivers seat are fulcrumed hand levers 33 and 34 one of which 1s connected to one of the bell-cranks, and the other to the other bell-crank by a rod 85 or other suitable connection. The levers 33 and 34: are provided with the usual toothed segments and spring vIn case of deep snows, where the spurs 18I cannot start the sleigh, an auxiliary propelling mechanism is employed. This mechanism comprises a pair of levers 86 each loosely inoivinted at one end on a crank 37 on the The levers are of suoli a length that when their free ends are released, they extend at an inclination to the ground, the
free ends being engageable therewith. lVith the levers in this position, when the shaft 10 `is turning, said levers operate to push, the sleigh. forwardly. l/Vhen not in use they may be elevated and held in such position by f means of a catcliBS carried bythe sleigl'il.
On the cranks 37 is also mounted a 'second pair of levers 39 operating in the same'manner as the levers 3 6, but extending 1n an opposite direction so that when they are swung downwardly into operative position, the sleigh will be backed. To the hind l i sleigh body are fastened leaf springs 40 having at their free ends slots 41 through which the levers 36 and 89 loosely pass, and whereby they are guided. The springs have suflicient flexibility to permit'the levers to be elevated and placed in the catches 38'. Fig.
means for normally holding the sprockets f spread apart, and means for pressing the lower stretch of the cham outwardly to ad Vance `the spurs, said outward movement of tho chain beingaccompanied by a movement of the sprockets toward each other.
2. In a sleigh p|;'opeller,'the combination with the runner, ofan endless chain, spurs carried by the chain, a pair of sprockets for guiding the lower stretch of the chain along the runner, said sprockets being movable toward and from each other, yielding means for normally holding the sprockets spread apart, a spring supported frame supported by the runner, and a pair of rollers carried by the frame, and engage'able with the lower stretch for pressing thesaine outwardly to advance the spurs, and means for elevating the springsupported frame.
3. In a sleigh propeller, a drive shaft, a crank on said shaft, levers pivotallyv connected at one of their ends to the crank, and extending in opposite directions, and at an inclination to the ground, the free ends of the levers being in contact therewith, and means for holding the levers in elevated position to clear the ground.
