WILBER J. PINE, OF \VAUKAU, WISCONSIN.

ICE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 485,114, dated October 25, 1892.

Application filed September '7, 1891. Serial No. 404,999. (No model.)

To wZZ whom it may concern:

Be it known that I, WILBER J. PINE, a citizen of the United States, residing at Waukau, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Ice-Cutting Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to improvements in machines for cutting ice into blocks or cakes for packing; and the object of my invention is to provide a means of sawing the ice with a circular saw.

In the accompanying drawings, Figure l is a plan view; Fig. 2, a rear view; Fig. 3, a side view with one of the wheels removed. Fig. at is a perspective view. Fig. 5 is avertical section of the two-way bearing-box. Fig. 6 is an end View of the same, and Fig. 7 is a rear View of the shifting device.

Similar letters refer to similar parts thro ughout the several views.

The machine is to be drawn by horses hitched to the tongue A, and the power is geared from one of the carriage-wheels B B,

spikes a a a a being provided in the tires to engage the ice and keep the wheels from slipping. The wheels B B are attached to the axle O, and the axle revolves with the wheels in the boxes D D; but each wheel may be provided with an ordinary ratchet-hub, such as is used in harvesters, so that when the machine is backed the wheel revolves upon the axle. Within the folly of one wheel is a series of cogs e e e, &c., which engage the cogs upon the wheel E, which is operated out and in to stop or start the machine by the lever F. The wheel E slides loosely upon the shaft 5 f, but is keyed thereto by the key 0 and regages the corresponding cogwheel K, attached to and which revolves the saw-shaft z.

I is the circular saw attached to the shaft i.

The box is a double box receiving the shaft h and the shaft 1' and adapted to rise when the saw is raised in the frame. Within the box It is a projection or shoulder which turns in a groove near the lower end of the shaft h, and the shaft is thereby prevented from rising out of the box.

m on is the saw-frame, and n n the boxes supporting the saw-shaft. These travel up and down in grooves in the frame and are raised and lowered by the screw-rods 0 o 0 0,

one of which is provided within each corner of the frame. To the tops of these rods are attached small cog-wheels r r r a, which engage and are operated by the large cog-wheel S, connecting with the hand-wheel T. By revolving this brake the rods 0 o o o are revolved simultaneously, and the screw-threads, operating within the shaft-boxes 'n at below, raise or lower the saw as the brake is turned forward or backward.

t t are small wheels traveling upon the ice to support the saw-frame. m a: are guides, one of which travels each time in the former seam or cut to regulate the size and uniformity of the strip or cake of ice. Each guide is operated by a spring-lever z.

By the several gears describedIam enabled to get the requisite speed or revolution to the saw.

Heretofore it has been the custom to plow a seam or cut in the ice about half through and then saw the rest by hand. In the same manner I provide a means of sawing the ice in a much shorter degree of time.

It is not intended by any machine-sawing to saw the ice clear through, as some portion must be left to bear the weight of the horses and machine.

In operating my machine the driver sits in the seat W." The saw is first raised within the frame m m. By pushing the lever F forward I throw the wheelE out upon the shaft, so that it engages the cogs e e c with the felly. By means of the several connecting gears above described the saw is set in motion. One of the guides at is then adjusted in the former cut, and after the saw has acquired the requisite speed of revolution I revolve the hand-brake T and lower the saw to the ice. When desiring to stop the machine, I pull upon the lever Fand throw ofl. the slipgear, hereinbefore described. The driver sitting on the seat W, can easily operate the levers F and Z and revolve the hand-wheel T to regulate the out. This is all that is required in operating the machine. raised and lowered, the perpendicular shaft h is also raised and lowered, and the top thereof, moving up and down upon the gage 11 indicates the depth of the cut. This gage can be easily seen by the driver.

It is advisable that a rocking tongue A be provided, that will turn sidewise, so that if the horses turn suddenly to one side the position of the saw and the guide will not be changed.

WVh-at I claim as my invention is 1. In a machine for cutting ice, in combination, a suitable supporting-frame, a revolnble saw which is adapted to be revolved and As the saw is moved vertically, operating-shaft 71-, saw-shaft i, and a two-way vertically-moving bearlngbox is, receiving shafts h and z'and provlded internally with a projection which turns in a groove near the lower end of the shaft h, whereby said shaft is prevented from rising out of the box, substantially as described.

2. In a machine for cutting ice, in combination, a suitable supporting-frame, a revoluble saw which is adapted to be moved vertically by means of the saw-frame mm,boxes 72, moving in grooves in the saw-frame, rods 0, cog-wheels r, cog-wheel S, meshing With the cog-wheels r, and the operating hand-Wheel T, and means for revolving the saw, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

INILBER J. PINE.
