ICE-SAWING MACHINE.

Specification of Letters Patent.

Patented Jan. 21, 1919.

Application filed August 30, 1917. Serial No. 188,965.

To all whom it may concern Be it known that we, BYRON B. PHILLIP and MALCOLM GIFFORD, citizens of the United States, residing at Hudson, in the county of Columbia rand State of New York, have invented a new and useful Ice-sawing Machine, of which the following is a specification.

This invention has reference to ice sawing machines of the kind shown and de-- scribed in our prior application No. 178,452, for ice sawing machine, filed Julyl 3, 1917.

The object of the invention is to provide a simplified construction over that shown in the aforesaid application, both types of ice sawing machines being of the kind known as one-man movable or traveling machines, because they are capable of operatingunder the guidance of a single man, who travels in front of the machine and draws it along, being assisted by the revolution of the saw.

The invention comprises a sled on which there is mounted a frame for supporting a motor, either of the explosion or electric type, and a saw, or saws, for cutting the ice. Mounted on the sled are guides whereby the sled, and with it the parts carried thereby, may be directed by a previously cut groove in the ice.

In order to greatly simplify the structure both in construction and operation, the motor frame with the parts carried thereby is pivotally mounted at the center of gravity as measured between the ends of the structure so that the saw may be raised and lowered, and the parts pivotally carried by the sled will automatically maintain the position to which they may be adjusted without the necessity of special fastening devices.

The invention will be best understood from a consideration of the following de tailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that, while the drawings show a practical form Vof the invention, the latter 1s, not confined to any strict conformity with the showing of the drawings but may be changed and modified so long as such changes and modifications come within the scope of the appended claims.

In the drawings:

Figure 1 is a side elevation of an ice sawing machine embodying the invention, and employing an explosion engine as a power unit;

Fig. 2 is a plan view of the structure shown in Fig. 1, with some parts broken away;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig. 4 is a section on the line 4 4 of Fig. l;

Fig. 5 is a side elevation of a portion of the machine of Fig. 1, but having an electric motor as the prime mover;

Fig. 6 is a plan view of the structure shown in Fig. 5;

Fig. 7 is a rear elevation of the structure shown in Figs. 5 and 6, but omitting certain parts.

Fig. 8 is a vertical sectional View on an enlarged scale showing the connection between the runners, the drop bar and the ily Y wheel casing.

Fig. 9 is a horizontal sectional view showing the connection between the Hy wheel casing, the tube which inclosed the transmission shaft, and the rear end of the sled frame.

Referring to the drawings and more particularly to Figs. 1 to 4, there is shown a sled made up of runners 1 secured together and spaced apart at the rear endby a bar 2 which may be of channel steel or other suitable form of structural material reinforced by braces 3 connected to the bar 2 and to the sled runners 1, so that the parts are sub*l stantially connected.

The runners 1 are shown as of the solid type, but it is to be understood that they may also be made of skeleton type. The particular construction of the runners not entering into the present invention, no detail description thereof isgiven.

Attached to and rising from the top of the runners forward of the braces 3 are journal bearings 4 in which are journaled the ends 6U shaft 23 are in alinement and the 'direct' The frame 6, in the structure of Figs. 1

to 4, serves as a support for the explosion engine 9V having its power shaft extending lengthwise of the frame 6 and of the sled carrying the frame 6. The engine 9 is provided with a fly wheel casing 10 and the casing has supporting members 11 on opposite sides carried by the longitudinal bars 7 of the frame 6, which latter is made fast to the shaft 5 near the corresponding ends the bars 7.

The construction of the connections be' tween these parts is very clearly shown in Figs. 8 and 9. Bolted to the fly wheel casing Y at each side is a vertical plate 11a, and each plate as well as the bar` 7 are secured to the shaft 5 by fastening 11b, each member 11 .being bolted to the bar 7. Fastenedto each member 11 is an angle plate 11C, which is also bolted to the opposite ends of cross bar8.

At the other end the frame 6 has brackets 12 secured thereto on opposite sides, and these brackets carry handles 13 ending in handholds 14, the handles13 being connect-- ed together near the handholds by al rod 15 or in any other appropriate manner.

Fast to and forming a cover for the fly wheel casing 10 is an enlargement or cap 16 on one end of a tube 17, the cap 16 being made fast to the fly wheel casing by bolts 18 which pass through the ends of bars 8 and into the fly wheel casing as shown in Fig. 9. The tube 17 extends lengthwise of thesled andV beyond that end of the latter having the cross bar 2. At. the outer end of the tube 17 there is secured a head blocl; 19 in which there is journaled a shaft 2O extending crosswise of the longitudinal aXis of the sled and provided within the head block with a bevel gear wheel"21.V The shaft 2O constitutes a saw arbor and may carrya single saw 22 as shown in the drawings or more than one saw if such be desirable.

Extending through the tube 17 Vand journaled in the head block 19 is atransmission shaft 23 carrying within the head block a. bevel 'gear 2K1 meshing Vwith the bevel gear 21. This shaft 23 is long. enough to reach Vthe vcrank shaft of the engine 9V and is cou'- pled thereto so that the 'engine shaft and the drive of the shaft bythe engine is obtained.

The head block'is made in two'sections,

as shown in Figs. 1, 2 Yand 3,` being divided ofV along a horizontal line intersecting the saw arbor. The sections are bolted together, and

are flanged at the inner end to meet the flanged outer end of the tube 17 to which said sections are bolted. The head block is closed atY the top by a cover and is hollow inside forming a chamber to contain oil thereby providing an oil-tight gear case in which the gears run continuously in an oil bath. p The head block also provides bearings for the saw arbor and the transmission shaft. Carried by the head block 19 is a gage member 25 capable of being adjusted up and down and is held in adjusted positions by a set screw 26. The lower end of the gage member 25 is roundedas indicated at 27, so as to engage and readily travel upon the surface of ice thereby serving as a third runner. Extending across the sled and journaled in those'ends thereof remote from the bar 2 aretwo rock shafts 28 and 29, each carrying a guide blade 30 which may be adjusted lengthwise of the shaft and held in adjusted position by a set screw 31.

Secured to each shaft 28 and 29 is a handle 32 individual thereto and movable over a segment 33 having recesses 3st into and out of which the respective handles may be moved. In this way, one of the guide blades 30 may be made to travel in a groove in the ice to direct the movement of the sled over Y the ice. Y

Instead of using an explosion engine such as the engine 9, an electric motor 35 of any suitable type may be employed as shown in Figs. 5, 6 and 7. This motor is carried by a hanging support 36 bolted or otherwise secured to the side bars 7 of the frame 6 which. support may forni a permanent part of the frame 6, since it need not beY removed in thev motor by a gasolene is being rapidly rotatedV in the proper direc-4 tion, Vso that on an operator grasping the handholds and drawing the sled toward the operator, which would be toward the left in Fig. 1, and with the saw entering the ice, the latter is cut to a desiredV depth, the whole structurebeing guided the proper blade 30 `entering a cutlalready made.V InV this manner, the saw cuts a groove into the l V ice at the desired distancefroni the previoui'sly madet cutand when the cut being made.

is long enough, it is only necessary to readjust the machine: to form the next adjacent cut at a definite distance from the one just cut. The surface of the ice may therefore be scored or cut nearly or wholly through as the operator may desire and be ultimately divided up into blocks of a chosen size.

When it is desired to move the devices over the ice without cutting, the handle end of the frame 6 is depressed, thus raising the saw end, such position of the parts being shown in full lines in Fig. 3.

When it is desired to cut a groove in the ice, the frame 6 is rocked on its pivot support sufliciently to cause the saw 22 to enter the ice to the desired depth.

These various positions of the saw with respect to the ice are maintained automatically, since the whole structure is a balanced structure because the pivot support of the frame 6 is at the center of gravity of the frame 6 and parts carried thereby lengthwise ofl the machine. Consequently, any forces commonly met with in the operation of the machine would not be liable to disturb the balance and it is not necessary for the opera-tor to control the machine in any other manner than to cause it to follow a straight path.

By mounting the rockable parts of the structure upon an axis transverse of the sled and so related to the sled and to the rockable parts that the latter are supported at the center of gravity lengthwise of said rockable parts, the adjustments for cutting or for transportation are extremely simple and fastening devices of any kind become unnecessary.

By forming the main frame 6 of the rockable parts of the machine to receive either an explosion engine or an electric motor, different vpowerunits become interchangeable and hence no material change is needed in the manufacture of the machine to adapt it to different types of power units.

These features, moreover, lighten the structure so that its control is readily within one-man power.

Although an explosion engine or an electric motor of suflioient power is quite heavy, the arrangement whereby the rockable parts including the motor and thesaw are balanced with both the motor and the saw rocking, the construction is made much simpler than would otherwise. be the case, and a direct drive of themotor and the saw without joints or iexible connections becomes commercially practicable.

The tubular` member 17 with its V expanded end or `cap member 16 serves to protect rotating parts both of the prime mover and of the shaft 23 from contact with and injury by particles of ice thrown off by the saw.

It will be observed that the elongated saw support formed by the parts 16, 17 and 19, is fixed to the frame as well as to the moto-r, and constitutes a continuation of the transmission housing, and thereby forms a connection or support of the motor to the frame.

The handle 18 with the handholds 14 provide for drawing, guiding and rocking the machine. virtually a single handle or lever for all three controls.
