JAMES H. FISCH AND JOSEPH C. BABST, OF FERGUS FALLS, MINNESOTA, ASSIGNORS TO FERGUS FALLS ROTARY ICE PLOW 00., OF FERGUS FALLS, MINNESOTA.
ICE-CUTTIN G MACHINE.
To all whom it may concern:
Be it known that we, JAMES H. FisoH and Josnrrr C. BABST, citizens of the United States, residing at Fergus Falls, in the county of Ottertail, State of Minnesota, have invented a new and useful Ice-Cutting Machine, of which the following is a specification.
This invention relates to improvement-s in ice cutting machines, the primary object of the invention being the provision of a motor driven sled construction provided with vertically adjustable and spring depressed propelling means or wheels, said wheels being arranged in pairs and provided with means for vertically adjusting the same with relation to the surface traversed, in combination with means for operably connecting the same with the motor, whereby the machine is driven in the desired direction over the ice and simultaneously cuts the same.
A further object of this invention is the provision of a motor driven ice cutting machine of the sled type, provided with a multicylinder engine, with a vertically adjustable cutting mechanism operably connected with said engine, and with a vertically adjustable spring tension driving mechanism operably connected with the engine, the tractors of said driving mechanism being adjacent to or slightly in advance of the cutting edge of the saw, so that solid ice will always be engaged thereby.
lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.
In the drawingsFigure 1 is a side elevation of the complete machine, the cutting saw being in operable position. Fig. 2 is an enlarged detail side elevation of the driving mechanism. Fig. 3 is a top plan view of the frame supporting the same, the vertical frame or lifting member being broken away. Fig. 4 is a detail perspective view of the driving wheel construction. Fig. 5 is a diagrammatic view showing the relative position of the motor shaft and propelling Specification of Letters Patent.

wheels. Fig. 6 is a top plan view of the complete machine with parts removed. Fig. 7 is an enlarged detail and sectional view showing the connection of the propelling wheel carrying frame to the main shaft.
Referring to the drawings, the numeral 1 designates the frame of the machine, provided with forward transverse connecting means 2 and with the operating platform 3. The said frame is mounted on runners as shown.
Mounted in the forward portion of the frame is the motor frame at carrying the oppositely disposed multi-cylinder motors 5 and 5, which are coupled for operation in unison, so as to drive the shaft 6 and the fly wheels 6. The shaft 6 is provided with a series of transmission wheels, one of which is connected to the belt or sprocket chain 7 which operates the shaft 8 and the fly wheel or clutch 9, while leading from another one of the drive sprocket wheels of the shaft 6 is an endless belt or sprocket chain 10 which operates the shaft 11 mounted in the bearings 12, and carrying the circular ice cutting saw 13. This ice cutting saw is vertically adjustable through means of the beams 14, whose rear ends are pivoted to the shaft 6 as an axis thereof, and are provided with the lugs 15 having the links 16 and crank arm 17 operably connected thereto, so that the rock shaft 18 and lever 19 may be operated to raise and lower the forward free end of the beams 14 and consequently regulate the cut of the saw 13, or move the same and hold it out of operable relation with the ice. At the forward end of the beams 14, is the usual gage or stop 20. In order to resiliently hold the beams 14 of the saw 13 in operable relation, the arms 21 are carried at the pivotal end of the beams 14, the coiled spring 22 having its pins 23 connected to the arm 24 to support it from the lower end of the vertical frame 28. Through the means of the lever 26, the clutch mechanism 9 and 9 is operated, this construction being identical with the construction set forth in applicants application filed April 21, 1910, Serial No. 556,813, (Patent No. 1,009,884, November 28, 1911, 628) upon which the construction hereinafter to be set forth, is an improvement.
Secured between the uprights 28 and 29 of the frame of the machine, are the L- shaped brackets or frames 27, which provide a bearing means for the reception of the rods 30, each one of which is provided with the lower forked end 31, and with the upper right angled end 31, this upper right angled end having adjustably connected thereto and to the support 27, the coiled spring 32 which has a tension to pull down upon the arm 31', so as to hold the lower forked end normally toward the surface traversed. In order to raise and lower the stems or rods 30, each one is provided with the eyed lug 33, which has connected thereto from above, the lower end of the flexible connection or chain 34, there being two chains 34, whose upper terminals are connected to the outer ends of the levers 34, carried by the rock shaft A, the operating lever 34" of the rock shaft being connected through the medium of the long link or rod 35, to the operating lever 36, which is pivoted to the longitudinally horizontal strips 37 of the main frame of the machine. By this means the movement of the lever 36, will operate the rock shaft, so as to raise the stems and their forked ends 31 simultaneously, the purpose of which will presently appear.
In the lower ends of the forked terminals 31 are mounted the drive wheels 38, the detailed construction of which is clearly set forth in Figs. 3 and 4 of the drawings.
Each one of these wheels are arranged with the parallel rims, so as to provide a double tread wheel, whose spokes 39 are connected upon opposite sides of the web 40 of the hub 40, said web being provided with the sprocket portion 41, and the hub 40 being journaled upon the shaft 42. This shaft 42 is mounted at the lower end of the forked ends 31 and in the forward free ends of a sectional frame which forms a vertically ward the surface traversed, manually operi ated means for regulating the movement of the tractor wheel toward the surface travj ersed, a rock shaft journaled transversely of the frame above the tractor wheel, means connecting said rock shaft to the stem, and 11113111181113] actuated means connected to the 1 rock shaft for elevating the stem to regulate the downward movement of the tractor wheel.
swinging arm and which is composed of the sections 43 and 43, the same being held together by means of the slot and bolt adjust ing devices 43 and held spaced apart by means of the transverse bars 44 and 44 respectively, these transverse bars 44 and 44" being held against inward movement, while the clamping devices 43 are at the same time assisted, by means of the adjusting screws 45, as clearly illustrated in Fig. 3 of the drawings.
The inner sections 43 of the pivoted members are connected to a rod 46, which itself is carried by an arm 47, whose pivotal point or axis is the shaft 46, and mounted upon this shaft and rotatable therewith is the sprocket wheel 48, which through the medium of the sprocket chain 49 transmits motion to the sprocket wheel 41 and consequently the drive wheel 38. It will thus be seen that the tractor wheels of the present device are disposed adjacent to or slightly in advance of the forward cutting edge of the saw, so that the said wheels will encounter solid ice to push the sledded frame to better advantage.
As clearly shown in Fig. 4 of the drawings, each one of the treads of the wheels 38 is formed angular as at 50 and is pro vided with the removable teeth 51, which are arranged in staggered relation to each other about the treads of the respective sections of the wheel 38.
As shown in Fig. 5, the shaft 8, througli .the clutch 9-9, operates the shaft 52, and
through the bevel gears 53 and 54, operates the shaft 46 and in turn rotates the propelling wheels 38.
From the foregoing it is evident that by means of the provision of the vertically ad-. justable frames or rods 30 carrying the forked ends 31 and their respective double treaded wheels, and the pivotal arrangement of the horizontally disposed frames 43 and 43, respectively, that the said double treaded wheels may be lifted toward and from the surface traversed, so as to provide the proper frictional contact therewith for the propulsion of the machine. It will also be seen that by providing the tread with the removable surface engaging teeth, that l any number of these may be used and as they areworn that the same may be removed and replaced.
What is claimed is: j 1. In an ice cutting machine, a sledded main frame, a rotary saw journaled therein, a vertically swinging arm having its free end terminating adjacent to the forward edge of the saw, an arm upon one side of the saw, a shaft mounted in the free end of the last arm, a tractor wheel mounted upon sa d 1 shaft, a stem rising from said shaft, a spring connected to the stem and to the main frame for resiliently holding the tractor wheel to- 2.
