Application led June 17, 1919. Serial No. 304,757.

To all whom t may concern.'k

Be it known that I, ELMER E. STONER, a citizen of the United States, residing at Stroudsburg, in the State of Pennsylvania, have invented new and useful Improvements in Ice-Cutting Machines, of which the following is a specification.

This invention relatesto ice cutting apparatus and the principal object of the invention'is to provide a plurality of band saws for cutting the ice into blocks. y

Another object of the invention is to provide means for feeding the ice to the saws, said feeding means engaging the under face of the cake with means for adjusting said means to suit varying thicknesses' of ice.

Still another object of the invention is to provide means whereby a cake of ice will be cut first into a plurality of strips and then said strips will be cut' into blocks.`

The invention also consists l in certain other features' of construction and ,y in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims. Y

AIn describing my invention iny detail, reference will be hadl to the accompanying drawings wherein like characters denote like or corresponding parts throughout the sev.- eral views, and in which n Figure 1 is a plan view of the invention;

Fig. 2 is a section between the feed rollers andthe band saws looking toward the saws, Fig. 1; l

Fig. k3 is a section betweenthe feed rollers and the saws looking toward the feed rollers, Fig. l; y

Fig. 4. is an end view with one of the sawsupporting frames tilted into inoperative position; f

Fig. 5 is a view of the heating means fo the device; l l

Figs. 6 and 7 are detailed views.

Fig. 8 is a view of a modification. l Y

In these views 1 indicates the supporting frame which is built in the body of water from which the ice is to be taken and which is of L-shape and through which the blocks of ice are passed to be operatedupon by the cutting mechanism. This frame is provided with the uprights 2 and the saw frames 3 are pivotally connected to these uprights so that the said saw frames may be moved into either a vertical position or a horizontal position. lVlien in a horizontal position the saws are inoperative `and all parts ofthe mechanism are raised above the water level. As shown, the saw frame is of rectangular shape and its lower member supports the shafts 4 in spaced relation while the upper member supports the shafts 5, each shaft 5 being located directly above` one of the lower shafts `4. The shafts 4 and 5 have secured thereto the pulleys 6 for supportingy the band saws 7, As will be seen, the diameters of the pulleys are such as to support each stretch of the saw the same distance apart so that uniform strips of ice will be cut by said saws.

The shafts 5 are driven by the drive shaft 8 whichis connected tothe shafts 5 by the beveled gears 9. The shaft 8 is connected in any desired manner with any type vof motor. feeding means and such means consist kof a plurality of spur wheels l() mounted 'on the shaft 11 which has its ends journaled in boxi'ngs 12. These boXings are slidably mounted in the depending frames 13 which are secured to the main frame. These, def pending frames extend Adownwardly into the water so that the spur wheels willengage the under faceof the cake of ice. The means for sliding the boXingsto bring the spur wheels against the bottom of the In front of the saws'fI locate the y cake of ice consistof a screw-threaded shaft f this way the spur wheels may be raisedy and lowered so that they will properly engage the bottom face of the cake of ice and this engagement is yieldable due to the coiled springs. The shaft 11 is connected with the actuating means by the flexible shaft 11.

As will be seen I place one of the cutting means with the feeding means at a point where one part of the yL-shaped frame connects with the other part so that as the cake of ice is driven through this'part it will be cut into strips, as shown in Fig. l. Then as the block is moved at right angles it will come in engagement with the other cutting means so that the strips will be cut into blocks. As will be seen, the drive shaft 8 is extended and is connected with the shaft 8 of the other set by the beveled gears 8X so e that one set will be driven by the other set. I provide heaters 18 which consist of steam coils, adjacent the upper portions of the apparatus so as to keep the same free of ice.

In the modification shown in Fig. 8 the means for feeding the ice to the saws consists of en-dless chains 2O which pass over sprocket wheels 2l located on shafts 22, one of these shafts being driven in the same .ianner as shaft l1 is driven. I may aiso provide small rollers 23 carried by brackets 24 for preventing the icefrom pushing the saws rearwardly. Y

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent. j

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What I claim is l. An ice cutting apparatus comprising a supporting frame built in a body of water from which the ice is to be gathered rand formed in the shape of a channel through which the blocks of ice are to be passed, a saw frame pivotally mounted in said frame and extending across the channel, said frame having its pivotal points arranged above the water` level so that when the frame is swung into horizontal position it will be above the water level, transversely arranged shafts in said saw frame adjacent each side thereof, pulleys on said shafts, band saws carried by said pulleys, means for driving the shafts of one row and manually operated means for swinging the saw frame on its pivot to move the saws into vertical and operative positions or into horizontal and inoperative positions.

2. An apparatus for cutting ice comprising a frame, located in the body of water from which the ice is te `be gathered aud made in the form of a channel through which the blocks of ice are passed, avsaw frame pivotally mountedvin the supporting frame and extending across the channel, said frame having its pivots arranged above the water level, a row of transversely arranged shafts at each side of the saw frame, pulieys carried by said shafts, band saws supported by said pulleys, means for driving one row of shafts and power driven means for feeding the block of ice against the saws. 8. in apparatus for cutting ice comprisin@V aV frame, located in the body of water from whichtheA ice is to be gathered and made in the form of a channel through which the blocks of ice are passed, a saw iframe pivotally mounted in the supporting frame and extending across the channel, said frame having its pivots arrangedy above the water level, a row of transversely arranged shafts at each side of the saw frame, pulleys carried by said shaft, band saws supportedk by said pulleys, means for driving one row of shafts and power driven means .for feeding the bloclr of ice against the saws, said means consisting of uprights carried by the supporting frame infront of the saw frame, slidingboxings supported by said uprights, a shaft journaled in said boX- ings, means' carried by the shaft for engaging the under face of the blockk of ice for forcing. it againstthe saws, yieldable means for vsupportingthe boxings and` means for adjusting the boXings vertically.

4. An apparatus for cutting ice comprising a frame located in the bodyof water from which the ice is to be gathered and made in the form of a channel through which the blocksof ice are passed, a saw frame pivcted in said supporting frame and extending across the channel, saws supportin said saw frames, means for actuating the saws and heating means carried by the saw frame for preventing the formation of ice on the saws and their associated parts. i 5. An ice cutting machine comprising a supporting frame located in the body of water vfrom which the ice is to be gathered and formed to provide an L -shaped channel through whichL the iceis passed, apair of saw frames pivotally mounted in the supporting frame, one in each part of the channel, saws carried by said saw frames, means for actuating the saws and feeding means located in front of each sawframe for feeding the ice against the jaws, one set of saws cutting the bieck of ice `into strips and the other set ycutting said strips into smali blocks.

In testimony whereof I aiiix my signature.
