ICE-CUTTING DEVICE.

Specification of Letters Patent.

Patented Apr. 8, 1913.

Application filed May 31, 1912. Serial No. 700,671.

.water into a series of blocks of the desired size; and more particularly to a hollow, cross-cut separating member into which a warm medium may be introduced. A somewhat similar device has been disclosed in U. S. Letters Patent No. 876,015; and it is the object of the present invention to improve the device therein disclosed by constructing the same entirely of sheet metal, preferably in one piece, and thereby greatly reducing the liability to leakage; and, furthermore, to afford a flexible cutter by providing between the walls of the same a resilient member, and which member will at the same'time reinforce the cutter as a whole.

The construction of the improved cutter is such that all rivets and solder on the side wall portions are dispensed with so the cutter may be freely drawn from between the blocks after having become detached therefrom. Provision is also made for the more ready drainage of the cutter after its removal from the freezing tank.

The nature of the invention will best be understood when described in connection with the accompanying drawings, in which Figure 1 is an elevation of the improved cutter. Fig. 2 is a similar View but with one wall removed. Fig. 3 is a transverse vertical section taken on the line 3-3, Fig. 1, and looking in the direction of the arrows. Fig. 4 is a plan of the cutter. Fig. 5 is a horizontal section taken on the line 55, Fig. 1.

Similar characters of reference designate corresponding parts throughout the several views.

Referring to the drawings, 10 and 11 designate respectively the outer walls of the cutter and are composed of a single piece of sheet metal suitably bent to form a hollow cutter. This may be accomplished, for example, by starting at the free end 12 of a corrugated portion 13 of the material, the purpose of which will hereinafter be set forth, then turning the metal back over and around the corrugated portion 13 to form the said wall 10 which extends some distance beyond the free end 12 of the said corrugated member. The metal is then turned back again to form the wall 11, which at its farther end is abruptly turned inwardly toward the wall 10 providing a lip 14, which is soldered to the end of the corrugated member 13, or otherwise suitably secured thereto. preferably to taper toward the free end of the member 13, which, of course, is likewise tapered to correspond by making the successive corrugations of less depth. The cutter is tapered also downwardly to enable the same to be more readily withdrawn from the blocks of ice. Of course, the corrugated member 13 might be made separately and insertedbetween the walls 10 and 11; but I prefer to make the cutter entirely of a single piece of the sheetmetal, as hereinbefore set forth.

In order to decrease the liability of leakage, the wall 10 is folded inwardly at the bottom to form an upwardly extending lap 15, the corrugated member 13 terminating at a sufficient distance from the bottom to prevent interference with this lap. The wall 11 is brought down over this lap and is cut away partly, as shown in Fig. 1, the seam being suitably soldered. A small lap 16, also, is turned from the side of the cutter over the bottom of the same.

At the top, the hollow cutter hereinbefore described carries a suitable head 17 which is riveted and soldered thereto to provide a water-tight joint; and this head is provided with suitable openings 18 for the heated water and to permit the escape of the air. These openings are provided in corresponding transverse cuts 19 of the head so that.

in setting the head on end to empty the cutter of the water, the same drains freely The walls 10 and 11 are made,

therefrom. The cutters, as a whole, are supported by suitable lugs 20 extending from the head 17; and are further provided with outwardly extending arms 21 whereby the form to the pressure thereon, making the cutter as a whole flexible .'and.-..providing, a spring action on both walls throughout their entire height. the walls of the same are pressed tightly against the corrugationsyand when the hot water is introduced within-thegcutters, these Walls will again spring into place and the cutter consequently readily loosens and can be easily witl' drawn. The construction here in .disclos ed whereby the cutter is made withoutany-rivets, or solder projecting upon itsactive external, surface, provides a cutter forced throughout its length by the corrugated member, ,13. and affords a sufiiciently strong and;,.at,the same time, flexible cutter.

I claimi,

1. A utting. device for use in the manufacture .ofartificial ice, comprising: a hollow sheet metal member, having flexible walls, anda reinforcing member held therein ,betweensaid Walls but unattached thereto, and. extending substantially throughout their entire Width.

2. A cutting device for use in the manufacture ofwartificial ice, comprising: a hollow sheet metal ,member, and a corrugated, reinfQrcing member held between the walls of thefsame.

3. ,A cutting. device for use in the manufacture of artificialic e, comprising: a single sheet of metal bent back upon itself, and a reinforcing memberr formed of one end thereofturned in between thewalls of said cutting ,device.

When the cutter is frozenin,

4. A cutting device for use in the manufacture of artificial'ice, comprising: a single sheet of metal bent back upon itself, and a reinforcing member formed of one end thereof turned in between the walls of said cutting device, the said turned in portion being corrugated.

, 5. A cutting device for use in the manufacture of artificial ice, comprising: a single sheet of metal bent back upon itself, and a reinforcing member formed of one end thereof turned in between the walls of said cutting device, the said turned in portion being corrugated and its end remaining free and unattached to the cutting device.

6. A cutting device for use in the manufacture of artificial ice, comprising: a single sheet ofmetal bent back upon itself, and a reinforcing member formed of one end thereo-fturned in between the walls of said cutting device, the said turned in portion being corrugated and its end. remaining free and unattached to the cutting device, and the said corrugations being of decreasing depth toward the free end.

7. A cutting device for use in the manufacture of artificial ice, comprising: a single sheet of metal bent back upon itself, a reinforcing member formed of one end thereof turned in between the walls of said cutting device, the said turned in portion being corrugated and its end remaining free and unattached to the cutting device, and a lap member extending upwardly from the bot tom of one of the walls and within the other wall.
