ERNEST H. FRANKAMP, OF REPUBLIC, KANSAS.

ICE-CUTTING MACHINE.

Specification 0 Application filed August To all whom it may concern:

Be it known that I, ERNEST H. FRANKAMP, a citizen of the United States, residing at Republic, in the county of Republic and State of Kansas, have invented certain new and useful Improvements in Ice-Cutting Machines, of which the following is a specification.

This invention relates generally to ice cutting machines, and has for its primary object to generally simplify and improve the construction and operation of such devices, as well as to increase their efiiciency.

A further object of the invention is to provide an ice cutting machine of such construction that the same may be easily moved across the surface of a frozen pond or river without the aid of draft animals,-and which may be accurately guided and controlled.

A further object of the invention is to provide a machine of the character stated which is equipped with improved means for moving the cutting element into or out of contact with the ice.

A still further object of the invention is to provide improved guiding means in connection with the ice cutting machine, which insures the latter of cutting blocks of uniform width.

With these objects in view together with others which will appear as the description proceeds, the invention resides in the novel formation, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In the drawings I Figure 1 is a side elevation of an ice cut ting machine embodying the invention,

Fig. 2 is a vertical sectional view taken substantially upon line 22 of Fig. 1,

Fig. 3 is a detail fragmentary perspective view of a portion of the guide apparatus, and

Fig. 4 is a top plan view of the improved ice cutting machine. v

Referring now more particularly to the drawings, 5 indicates generally the body of the vehicle constituting a part of the invention. This vehicle includes the body frame as shown having depending from the sides thereof, the supporting runners 6, so that the apparatus may be easily drawn over the ice, a handle or tongue 7 being secured to Patented Jan. 20, 1920.

one end of the vehicle to facilitate this operation.

Pivoted as at 8 to the rear end of the sled or vehicle, is a frame 9 which carries the cutting mechanism. The rear end of this cutter frame supports the laterally disposed shaft 10, to one end of which is secured the circular ice cutting saw 11, while the opposite end of the shaft is provided with a belt pulley 12. This pivotal mounting of the cutter frame 9 permits of the latter swinging in a vertical plane. I

Mounted at the rear end of the vehicle 5 and intermediate the longitudinal edges thereof, is the upstanding supporting post 13 to the upper end of which is pivoted a controlling arm 14:. It will be observed that this controlling arm is pivoted to the post above the upper surface of the vehicle, and the pivot for the same is supported by a strut 15 connected to the vehicle body. The upper portion of the arm 14 is connected with the cutter frame 9 by means of links 16, and it is therefore obvious that swinging movement of the lever 14 will cause the cutter frame to raise or lower. In order that the operator of the vehicle at the forward end thereof may control the movements of the cutter frame, a hand operated lever 17 is provided. This lever is pivoted as at 18 to the forward end of the vehicle frame and is equipped with a pawl 19 to engage with the segment 20. The hand lever 17 is connected with the movable arm 14 by a link 21.

The guide mechanism for the vehicle includes a pair of arms 22 extending outwardly from one side of the vehicle in spaced parallel relation and these arms are swingingly mounted upon the vehicle. In the present instance, these arms are turned inwardly at their inner ends as shown at 23, and these inturned ends are rotatably mounted in posts 24 upon the side of the vehicle. 22 are connected by a strut 24' and this strut is braced by a brace arm 25. The guide elements include a pair of blade members 26, one loosely arranged upon each of the arms 22. These blade members are connected by rods 27 so that the same are at all times firmly maintained in proper position. Each of the arms 22 is provided with threads as shown, and clamping nuts 28 are arranged in spaced relation upon the arms,

The arms and one upon each side of each of the blade members 26. From this construction, it is obvious that the blade or gage elements 26 may be adjusted longitudinally of the arms 22 by simply operating the clamping nuts 28.

Arranged upon the side of the sled and intermediate the forward and rear edges thereof is a post 35, to the upper end of which is secured the horizontally disposed beam 36. The outer end of this beam extends over the bars 27 connecting the guide or blade elements 26, and a cord or cable 37 is connected at one end to one of the said rods and extends upwardly therethrough and then passes through an eye 38 secured to the outer end of the said beam 36. The cable 37 then extends forwardly and laterally through suitable eyes upon the vehicle and is connected to the link 21 which establishes connection between the arm 14 and lever 17. By means of the cord 37, the operator of the cutting machine is enabled to easily raise the guide mechanism, it being understood that the latter swings upon the angularly disposed portions 23 of the arms 22.

The power employed for driving the circular saw 11 is derived from a motor indicated conventionally at 39. This engine may be 'of any approved type, and is positioned upon the sled or vehicle. The band wheel 40 of the engine has a belt 41 passing thereover, the said belt also passing over the belt pulley 12 upon the shaft 10. A belt tightener 42 is mounted upon one side of the vehicle and in direct line between band wheel l0 and pulley 12, and this tightener maintains the belt in proper tension.

In operation, the vehicle is moved out upon the surface of the ice and the engine is started. When the vehicle is in the proper position to cut, the hand lever 17 is operated so as to move the saw frame 9 downwardly,

whereupon the rapidly rotating saw 11 comes into contact with the surface of the ice. The depth of cut of the saw, will of course, depend upon the diameter of the saw and also upon the degree of vertical adjustment of the saw frame 9. Thus started, the vehicle is drawn at the proper speed over the ice. l/Vhen one out has been made in the ice,

j the vehicle is moved so that the blades 26 will engage within the said out, it being understood that the gages have been adjusted properly before being inserted into the groove, The engagement of the blades in the preceding cut will properly guide the ve hlcle, so that cuts spaced uniform distances apart will be made. This op i n i ntinued until a sufficient number of cuts have been made in the ice. Should it be desired to vary the distance between cuts, the adj usting nut 28 may be loosened and the blades 26 moved longitudinally uponthe sup? porting arms 22. WVhen it is desired to discontinue the operation of the machine, the hand lever 17 is moved forwardly, whereupon the saw frame 9 is caused to swing upwardly to disengage the cutting blade 11 from the ice. The guide blades 26 may be disengaged from the ice by pulling upon cord or cable 37.

From the foregoing it is obvious that I have provided an ice cutting machine of extremely simple and inexpensive construction and which may be operated and maintained at exceedingly low cost. The various parts constituting the machine are of simple character and may be readily assembled or taken apart, and the said parts cannot become readily disordered or deranged.

The foregoing description and the drawings have reference to what may be considered the preferred or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimensions, etc., as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In an ice cutting machine, a main frame, a cutter frame, pivoted to an end of the main frame, a guide frame pivoted to a side of the main frame, an operating lever, and connecting means between the operating lever and the cutter and guide frames for effecting simultaneous movement of the cutter and guide frames.

2. In an ice cutting machine, a main frame, a cutter frame pivoted to an end of the main frame, a guide frame pivoted to a side of the main frame, an operating lever, connecting means between the lever and cut ter frame including an arm and link, and a flexible connection between the said link and guide frame, the pivots being disposed to admit of the cutter and guide frames being simultaneously operated by means of the said lever.

In testimony whereof'I aflix my signature in presence of two witnesses.
