The means of forcingthe propelling wheels 17 a'nqbelg into the roadberl will now be deson Thel shait 1271s I Suspended from the rear end of the frame 1, there are provided a pair of V-shaped brackets 25. Extending upward from the inner surface of the bottom of these brackets 25, there are provided suitable hooks 26, to which are secured the lower ends of spiral tension springs 27. The upper ends of these spiral springs 27 are secure to suit-able hooks 28 on the ends of a cross bar 29. The cross bar 29 is secured in any well known manner to the end of a lever 30, which extends to the forward end of the frame, and rests intermediate its ends on a curved lock 31, which is secured in any well known manner to a transverse rod 32. The rod 32 has a loop 33 formed at one end,iwhich engages with a similar loop or ring on the end of the hanger '14:. The 0 -posit/e end of the rod 32 extends through a 13. By this means, the lever 30 is adapted to force the hangers 13 and 1a downwardly, thereby causing the propelling wheels to dig into the ground. The particular arrangement of the rod 32 with the loops 33 and 34: is such that the hangers 13 and 14:.

may move independently of each other, so as to allow for unevenness in the ground over which the slei h passes.

The lever 30 is operated by a suitable flexible connection 35, which is secured in any well-known manner to the forward end of the lever, and passes over suitable guide pulleys 36, 37 and 38 to the lower end of a cot lever 39, which is pivoted in any well known manner at 40. The foot lever 39 is located adjacent to the front seat in such a. position that the operator may readily op crate the same. It will thus be seen that the lever .30, by reason of its connection with the springs 27 holds the propelling wheels 17' and 18 in yielding cdntact with t e roadway, thereby permitting the Wheels to. spring up when they come in contact with an obstructio'n in the roadway.

In order to prevent the hangers 18 and 14, from wabbling from side vto side, and for the purpose of guiding them, there are provided suitable guides 41, 42, 4:3 and 44 se cured to the frame- Lin any suitable manner, and extending downwardly on each side-of the hangers 13 and 14.

The operation of the device will be readily understood from the above description. When the sleigh is going over smooth ground coated thickly with ice, a slight pressure is put on the foot lever 39, thereby causing the propelling wheels 18 and 19 to tend to jab into the roadway very slightly; However, if'soft snow with a slight crust on the top is reached, the pressure on the foot lever 39 must be increased perceptibly, in orderto force the sleigh along the roadway. In case a bare stretch of ound is encountered, the pressure on the cot, lever 39 may be in creased sufiiciently to raise the rear runners oop 34: on the hanger 10 entirely ofi the ground, supporting the majority of the weight of the sleigh on the propelling wheels 17 and 18. If desired in the running of the sleigh, one of the wheels may be hung up by a suitable hook attached to the framework and adapted to engage the hangers, thereby throwing it out oi. operation and permitting the sleigh to be propelled by one wheel. Any other suitable driving connection may be used between the shaft 12 and the propelling wheels 17 and 18, such as a chain-and-sprocket arrange ment,

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In an auto-sleigh, the combination with a frame, of a shaft rotatably supported on said frame, a pair of hangers pivotally supported on said shaft, propelling wheels on said hangers, a cross rod loosely connecting said hangers, a lever engaging said cross rod adapted to force said propelling wheels into engagement with the roadway, and means for operating said lever.

2. In an auto-sleigh, the combination with a frame, of a shaft rotatably supported in said frame, hangers pivotally connected to said shaft, propelling wheels connected to said hangers, a cross rod loosely connecting said hangers, a lever adapted to operate said cross rod to force said propelling wheels into engagement with the roadway, means for resiliently connecting said lever to the frame, and means for operating said lever.

3. In an auto-sleigh, the combination with a frame, of a shaft rotatably'supported on said frame, hangers pivotally connected to said shaft propelling wheels rotatably sup ported on said hangers, a cross rod loosely connecting said hangers together, a lever adapted to operate said cross rod, to force saidpropelling'wheels' into engagement with 4:.
