PATENT I STEAM ICE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 273,998, dated March 13, 1853. Application filed October 13, 1882. (No model.)

To all whom it may concern:

Be it known that I, JOHN JAMlESQN, of

.Rockaway Beach, in the county of Queens and State of New York, have invented a new and Improved Steam Ice OuttingMachine, of which the following is a full,clear,and exact description.

The object of my invention is to provide a new and improved machine for cutting a fieldconnect the rear ends of the cutter-frames and pass over the anchor-sleigh, and ropes which connect the front ends of the cutter-frames with windlasses or other winding mechanism on the sleigh from which the cutters are moved.

The invention further consists in an anchorsleigh carrying horizontal pulleys, and provided with wheels having studs which catch in the ice and holdthe anchor-sleigh in the desired position, which wheels can be locked in the desired position by suitable devices.

The invention also consists in a cutter-frame carrying cutters, and provided with adjustable legs which can be raised to lift the cutters from the ice when the same are not to beused, which legs have half-balls or rounded blocks at their lower ends.

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

Figure l is a plan view of my improved icecutting machine and the anchor-sleigh. Fig. 2 is a longitudinal elevation of the cutterframe, showing the same raised from the ice. Fig. 3 is an end elevation of the anchor-sleigh. Fig. 4 is a longitudinal elevation of the same.

On the sleigh A, which is drawn on the ice to the place Where the ice is to be cut, are mounted twowindlasses, B and B, which are i each operated independent of each other, which derive their steam from a boiler, C, also mount-. ed on the sleigh A. The frame D is provided with one or more rows-preferably three-of cutters, E, which increase in height from the front toward the rear end of the frame D, so

that the rear cutters will out deeper into the ice'than the front cutters. The said row of cutters is parallel with the sides of the frame D, and all the cutters of. one row are mounted and secured on a rod or bar which is adjustably fastened on the cross-bars F of the frame D, so that accordingly as the rowsof cutters are adjusted a greater or less distance apart blocks of ice of greater or less width can be cut.

Legs'G, provided at their lower ends with half-balls H, or other rounded blocks, are pivoted to the frame D at the. four corners, and the front legs, as well as the rear legs, are connected with each other by cross-bars. The legs at one side of the machine are provided with handles G, by means of which the legs can be erected, so that the cutters E will be above the ice. All the legs can be folded against the side bars of the frame D, so that the cutters E will rest on the ice and will cut into the same. The frame D is similar in every respect to the frame D. The front ends of the cutter-frames D 1) are attached to the ends of the ropes J and J, which are attached to the drums of the windlasses B and B, upon which they are adapted to be wound.

To the rearends ot' the cutter-frames D D a rope, K, is attached, to pass over horizontal pulleys L L on an anchor-sleigh M, which is provided with two side wheels, N, having a series of groups of studs, a, on its periphery, which studs serve to hold the sleigh in the desired position, and which project slightly from the lower edges of the runners of the sleigh, as shown in Fig. 4. The groups of studs 00 are so arranged that the distance from one group to another is about the width or length of a block of ice, so that whenever the anchorsleigh M is moved the distance of the length or width of three blocks of ice the circumference of the wheels N will have traveled such a distance that a group of studs a enter the ice, and thus prevent the slipping of the said sleigh. The wheels N are rigidly mounted on on the axle O,on which are also mounted wheels 1?, which are provided with a series of notches,- 1), into which the teeth on catches orloclrin'g- 2 erases guide-frame, R, of the well-known usual construction, is pivoted, which has prongs or studs which pass into a previously cut groove for the purpose of guiding the said cutterframe, so that all the grooves cut in the ice will be parallel. The ropes J and J pass over guide-rollers S and S on shafts in front of the drums of the windlasses, so that the cuttor-frames D will always be drawn straight, said guide-rollers to be suitably arranged'for this purpose.

It is evident that the distance between the pulleys L L and the pulleys L L on the anchor-sleighMcan be adjusted according to the desired size of the blocks of ice.

'As the cutter-frames D are preferably provided with three rows of cutters, each frame D cuts three blocks in either direction at the same time. If desired, the frames D may be provided with only one or two cutters; but as that would neutralize all the advantages gained by cutting by steam I prefer to use three rows of cutters, as such a cutter-frame can easily be drawn by a steam-engine which is not too heavy for theice to carry, and the ice can be out quite rapidly.

The operation is as follows: The sleigh A and the anchor-sleigh M are placed a proper distance apart on the ice that is to be cut. The cutter-frame D being at the anchor-sleigh M, by winding the rope Jon the drum ofthe windlass B the cutter-frame D will be moved toward the sleigh A and the cutters E will out three grooves corresponding to three blocks of ice into the surface of the field of ice, the legs G of the cutter-frame having been previously turned up against the side bars of the frameD whereby the cutters are lowered upon the ice. During the time that the cutter-frame D moves from the anchor-sleigh M toward the sleigh A the rope K pulls the cutter-frame D from the sleigh A toward the anchor-sleigh M; but the cutters of the cutter-frame D do not cut into the ice, as the legsGof the said frame D are turned down to be in a vertical position, so that the cutters E will be raised above the surface of the ice, the rounded blocks H at the lower ends of the legs Gr permitting the cutterframe D to move over the ice very easily and rapidly. When the cutter-frame D has arrived at the anchor-sleigh M the cutters ot' the frame Dare raised from the ice, and the cutters of the frame are lowered upon the ice, the-rope J is wound on the drum of the Windlass B, and the cutter-frame D is moved toward the sleigh A and cuts three grooves in the ice. The studs on the guide-frame It enter into one of the grooves previously cut by the frame D, and thus cause thegrooves cut by the cutters E on the frame D to be exactly parallel with the grooves cut by the cutters on the frame D. Then the sleighs A and M are moved forward such a distance that when the cutter-frame D, which is now again at the sleigh M, moves toward the anchor-sleigh A the outermost groove made by the cutters of the said frame D will be the regular width of a block of ice from the outermost groove previously out by the cutters of the frame D when the same moved from the anchor-sleigh M to the sleigh A. In this manner all the transverse cuts can be madein the ice, and then the sleighs A and M are so placed that the frames move at right angles to the grooves or cuts previously made, andthe rope K is passed over thepulleys L and L, as one dimension of the blocks is to be greater than the other. If the block is to be cut square, the rope K can always pass over the same pulleys, LL. Before the anchor-sleigh M can be moved the latches Q must be disengaged from the wheels P, and after the anchor-sleigh has been adjusted the wheels are locked in position by means of the levers or latches Q.

The rounded blocks H at the lower ends of the legs of the cutter-frames permit of moving them longitudinally or laterally very easily on the ice.

In place of the steam-windlassesshown, any p other suitable device for moving the cutterframes may he provided on the sleigh A, the steam-motor being preferred.

The above-described machine will be found and are inclined downward in'the direction of the draft, as shown, to form inclines for preventing the slcighs from being drawn toward each other by the cables.

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