JAMES F. CONNIFF, OF OCONTO, TISCONSIN STEAM-SLED.

SPECIFICATION forming part of Letters Patent No. 400,058, dated March 26, 1889.

Application filed July 24, 1888. Serial No. 280,894. (No model.)

To all whom it may concern:

Be it known that I, JAMES F. OONNIFF, of Oconto, in the county of Oconto and State of lVisconsin, have invented a new and Improved Steam-Sled, of which the following is a full, clear, and exact description.

'lhc obj-ect of the invention is to provide a new and improved sled to be propelled by steam-power and adapted to pull a train of sleds.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters ofl reference indicate corresponding parts in all the figures.

Figure l is a plan view of the power-sled. Fig. 2 is a side elevation of the same. Fig. 3 is a plan view of the train of sleds, and Fig. 4. is a side elevation of the same.

The improvement consists, principally, of the power-sled A and the train of sleds composed of the sleds B B &c., in which the front sled, B, is connected by suitable means to the rear end of the power-sled A. The latter is provided with a main frame, C, mounted on the sets of runners D and D', of which the runners D are pivotally connected at D2 to the under side of the frame C, and are provided with the upwardly-extending curved ends D2, passing into the vertical slots C', formed in the frame C. Thus the runners D have a vertical swinging motion, being guided by their curved ends D2 in the slots of the main frame C.

On top of the main frame C is mounted a boiler, E, of any approved construction and supplying steam to the engine F, connected in the usual manner with the main driving'- shaft G, mounted to rotate in suitable bearings on the main frame C. Each of the shafts G carries a sprocket-wheel, G, over which passes a sprocket-chain, G2, also passing over a sprocket-wheel, G2, secured on a shaft, H, mounted transversely at the rear end of the main frame C. Each shaft H is provided with a sprocket-wheel, H', over which passes a sprocket-chain, H2, also passing over a sprocket-whecl, H2, secured on a shaft, I, carrying a propeller-wheel, J. Each shaft I is mounted to rotate in suitable bearings formed on a frame, K, fulcrumed on the shaft H, so that the frame K is free to swing up and down, thereby holding the propeller-wheelJ in contact with the ice or snow. The periphery of each wheel J is formed by projections J, each of which has a transversely-exteiiding sharp edge, J2, adapted to cnt into the snow or ice, so as to firmly embed the wheel in the snow or ice, in order to propel the sled forward. As shown in Fig. l, two wheels J are employed; but any desired number may be used and di iven from the engine by any suitable means. The sleds B B &c., forming the train of sleds, connected with the power-sled A, are cach provided with a reach, L, connected with the next following reach bya coupling, L, of any approved construction. On each reach L are secured the transversely-extending beams II,

:for supporting the bed (not shown) of the sled,

and a king-bolt, O, passes through the said beams N and the reaches L into the bolster I), connected with a set of runners, Q. I prefer two sets of runners for each reach, as shown in Fig. 3,'and I connect the front runners by chains Q with a cross-shaft, Q2, mounted on the front end of the rear set of runners. A similar cross-shaft, Q2, is mounted on the front set of runners and carriesa forwardly-extending arm, Q3, having an npwardly-extending pin, Q4, passing through a slot, L2, in the rear end of the reach L, and serving to hold the set of front runners in place. The chains Q', connecting the front runners with the rear runners, permit the said runners to turn, as

is plainly shown in the forward part of Fig. 3.'

The operation is as follows: The steam supplied from the boiler to the engine F cames a rotary motion of the main driving-shafts G, which, by the connections of the sprocketwheels G and G3 and the sprocket-chain G2, impart a rotary motion to the shafts H. The latter, by their connections with the sprockctwheels H and HS and the sprocket-chain H2, impart a rotary motion to the shafts I, so that the propeller-wheels J are rotated in the direction of the arrow o', and the steam-sled A is moved forward as the transverse edge of the sharp edges J2, formed in the peripheries of the wheels J, pass into the ice or snow alter- ICO nnitely, so as to propel the Sled. The iraiin of sleds l.; 3 :ne connected with the rear end of The power-sled A, and are propelled forward hy the latter in the nninner above described.

VIlm'in ijhus full y described my invention, l Claim as new and desire to secure by lietters limitent* l.
