SLED FOR THE TRANSPORTATION OF ICE I1\T BLOCKS.

To all whom it may concern Be it known that I, NATHANIEL J. VVYETH, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Sleds for the Transportation of Blocks of Ice on Rivers and Lakes when Cut to the Depots 0r Receiving-Houses on the Banks of the Same.

The said improvement, the principles thereof, and mode in which I have contemplate the application of the same by which it may be distinguished from other inventions of a like character, together with the part thereof I claim to be my invention and desire to secure by Letters Patent I have set forth in the following description and exhibited in the accompanying drawing herein referred to which taken in connection form my specification.

Figure 1 represents a top view, Fig. 2 a side elevation and Fig. 3 a transverse section.

The sled somewhat resembles those in common use. The runners at, a, are formed of plank, connected together by cross ties b, b, 7), Z), Z). The runners should be formed in the usual way with their ends rounded upward, and may or may not be shod with iron at pleasure. There are projections c, c, on the rear of each of the tops of runners as seen in the drawings, for the purpose of preventing the blocks of ice resting on the sled from falling off backward when the sled is in motion. The upper edges of the runners should be beveled, so that the outer edges of each of them, will stand at about one inch higher than the inner ed es of the same runners as seen in the transverse section Fig. 8. Upon the beveled top of the surface of the runners iron plates or bars (Z, (Z, should be screwed or otherwise properly affixed, having their upper surfaces parallel with those of the runners. The upper and side surfaces of the bars cl (Z should be ground smooth, or brought at their junction to a straight line or angular edge in order that the ice may easily slide over the same and be retained on the rails or bars (Z (Z, or prevented from slipping sidewise by the bevel of the same. Shafts e c are attached to the sled in the usual manner.

I claim as my invention Beveling the top surfaces of runners of an ice sled substantially in the manner and for the purpose hereinabove described.

In testimony that the above is a true clescription of my said invention and improvement I have hereto set my signature this fourteenth day of October in the year eighteen hundred and forty.
