ICE-CUTTING MACHINE.

Application filed June 11, 1913.

To all whom it may concern:

Be it known that I, ALFRED GURRIE, citizen of the United States, residing at Delhi, in the county of Delaware and State of New ork, have invented certain which the following is a specification.

The present invention relates to certain new and useful improvements in ice cutting machines, and more particularly to that type of ice cutters in which the cutters are driven by a motor which is also adapted to be employed for propelling the frame upon which the cutters are mounted.

Among the objects of the invention is to provide an ice cutting machine which embodies novel features of construction where-' chine is traveling over ordinary ground and is not in operation.

A further object of the invention is topro-i vide novel and improved means for raising the cutting saws and adjusting them to any desired elevation so as to cut a certain depth into the ice.

A further object of the invention is to provide adjustable guides or markers which are hinged to the sides of the main frame of the machine and enable the that are being out.

In connection with the foregoing, it willv be observed that the construction of this machine is such that the frame which carries;

the engine and cutting equipment does not have to be raised from the surface of the, ice 1n order to elevate the saws above the With these and other objects in view, the invention consists in certam novel comb1- of the parts asv Specification of Letters Patent.

of the same with the rear portion of the operators platform and seat removed to show the mechanism beneath. Fig. 3 is a side elevation of the same. Fig. 4 is a detail perspective view showing the method of mounting the saws, and Fig. 5 is a detail perspective view of a portion of one of the guide boards, showing the manner of mounting the same for adjustment.

Corresponding and like parts are referred to the following description and indicated in all the views of the drawings by the same reference characters.

Specifically describing the present embodiment of'the invention, the numeral 1 designates the main frame of the ice cutter, the said frame being pointed at its forward end as indicated at 2, and being braced at its rear end by the cross piece 3. At the extreme rear end of the frame upright standards 4: and 5 are provided, the said standards being located upon opposite sides of the frame. The forward end of the machine may be provided with the platform 6 and operators seat 7.

The motive power for the machine may be furnished by a gasolene engine 8 which is shown as mounted upon a platform 8' extending transversely of the mainframe 1 at the rear of the forward platform 6. A. suitable fuel supply tank 9 is provided for bold ing the gasolene for feeding the engine. The shaft 11 of the engine 8 is disposed transversely with respect to the ice cutter, one end of the shaft being provided with a tooth or sprocket wheel 10, while the opposite end of the shaft is journaled within a suitable bearing 12 and projects laterally beyond the side of the frame 1, the extremity of the shaft having a pulley 13 applied thereto. This pulley 18 is belted to a second pulley 14 upon a counter-shaft 15 which is suitably journaled upon the frame 1. From this counter-shaft 15 power is transmitted to the drive shaft 16 through the medium of a short longitudinal shaft 16 and bevel gearing 16. A suitable clutch mechanism 15 is mounted upon the counter-shaft 15 for throwing the drive shaft 16 into and out of operation and reversing the direction of rotation thereof. A suitable lever C is provided for controlling this clutch mechanism 15 The drive shaft 16 is provided with a sprocket wheel 1'7 which is connected by connected by a link forward end 2 of the main frame is provided with a vertical shaft '19 which has a forked lower end 19* provided with the .tracwithin which a steering wheel 19 .is mounted. The upper; end of the vertical shaft 19 is provided? with a suitable handle 20 by means of which the said shaft can be rotated and the steering wheel 19 turned laterally for the pur-i pose of directing the movement of the ice cutter either to the right or to the left...

Both the clutch lever G and the steering handle 20 are located adjacent the seat 7} at the forward end of the machine so that? the operator can control the movements of;

the machine without leaving his seat.

Mounted upon the respective standards I 5 and 4 at the rear end of the machine are the vertical guide rods 21 upon which the saw shaft boxes 22 and 23 are slidably mounted. These boxes 22 and 23 provide bearings for the saw shaft 24 the ends of which project laterally beyond the said bearing boxes, and are threaded to receive the jam nuts 25 and 26 between which the circular saw cutters 27 are clamped. Suitably located on the shaft 24 is a sprocket 28 which is connected to the toothed fly wheel 10 of the engine 8 by the chain 29. In order that the bearing boxes 22 and 23 can be raised and lowered upon the vertical guide rods 21 for the purpose of adjusting the elevation of the saws, there is provided a rock shaft 30 which is journaled between the standards 4 and 5. Rigid with this shaft 30 is a bell crank lever 31 and an arm 32, the said bell crank lever and arm being applied to the shaft toward opposite ends thereof. The arm 31 of the bell crank lever is connected by a link 33 .to an eye 22 extending from the side of the box 22, while the arm 32 is connected by a similar link 34 to a corresponding eye 23 projecting from the side of the box 23. The opposite arm of the bell crank lever 31 is 35 to a hand lever H which is mounted upon the operators platform 6 at the forward end of the machine, thus making it possible for an operator sitting upon the seat 7 to raise and lower the saw shaft 24 by manipulating the lever H. It will be observed that the said rock shaft 30 is sufliciently high upon the standards 4 and 5 to provide for a proper clearance of the chain 29 under all conditions, and that the cross piece 3 of the frame 1 is cutaway as at 3 to admit of the chain.

running without interference vthen the shaft 24 is at its lowest position. As previously stated, the end portions of the saw shaft 24 are threaded from the boxes 22 and 23 all the way to the tips or extremities thereof and project some distance beyond the sides of ,the frame 1, thereby making it possible to obtain a lateral adjustment of the cutters 27 in addition to the vertical adjustment.

Each side of the main frame or carriage 1 is provided with a guide board .36 which is disposed longitudinally of the frame .and parallel to .the side bar thereof, the said guide zboards being adjustably mounted upon lateral arms 37 which are hinged .as at 39 to the frame and mounted .to swing in a vertical plane .to admit of the guide boards being raised and lowered. By reference to Fig. '5 it will be seen that these swinging arms 37 are each provided with a series of perforations 37 adapted .to receive the pins 36 .one of the pins being located .upon each side of the guide board 36 and the .said pin s being adapted to be fitted into any selected openings according .to the position of the guide board upon the swinging arm. Suitable diagonal braces 40 are provided between the swinging arms 37 upon each side. of the frame, and with this construction it will be obvious that the guide boards 36 can be adjusted in and out upon the arms 37 and can be swung upwardly into an inoperative position when not in use. With further reference to these guide boards it will be ob served that the same are held inian elevated position by means of the hooks 37 secured to the sides of the'frame 1, which ed to engage with suitable by the bars 37. v In the operation of the device, the machine is driven to the ice field with the cutters 27 and guide boards 36 raised into an inoperative position. W'hen the ice field is reached, the cutters 27 are lowered into engagementwith the ice and the machine then caused to be propelled across the ice in the desired direction so as to make a cut of the desired width and depth the full length of the field. The cutters are then raised, the machine turnedaround, and one of the guide boards 36 lowered into engagement with one of the cuts made by the cutter on trip. The cutters are then again lowered and the machine driven back across the ice field to make a cut as ;before,'the lowered guide board 36 sliding in one ofthe previous cuts so as to insure that the second strip of ice will be cut parallel to the first strip. This operation is repeated until the entire ice field is covered, the guide-boards always being maintained in engagement with one of the previous cuts so that the various strips of ice will all be parallel to each otherand accurately out to the desired size. u Having thus described the invention, what eyes 37 carried are adapt- I claim as new and desire to secure by Let ters Patent, is z- 1. An ice cutting machine including a carriage, standards on said carriage, a motor mounted upon the carriage, traction Wheels driven by said motor, guide rods applied to the before mentioned standards, journal boxes slidably mounted upon the said guide rods, a shaft journaled in the said boxes, rotary cutters upon the shaft, a driving connection between the shaft and the motor, and means for sliding the journal boxes upon the guide rods to adjust the cutters.
