GEORGE F. SAVOY, OF PEWAUKEE, WISCONSIN.

ICE-SEVERING DEVICE.

Be it known that I, GEORGE F. SAVOY, a citizen of the United States, residing at Pewaukee, county of Waukesha, and Stateof Wisconsin, have invented new and useful Im rovements in Ice-Severin Devices, of which the following is a 'spec' cation.

The ob'ect-of my invention is to provide a device or severing large blocks of ice into small rectangular pieces of uniform, convenient size and shape, by the use of an electrically heated instrument, whereby the waste and labor incident to the use of edged tools and the ordinary splitting rocesses is avoided, and whereby the bloclfs may be gotten out much quicker and in a neater and more attractive shape than by the processes heretofore employed. My invention is explained by reference to the accompanying drawings, in which Figurel represents a top View of a preferred form of my ice severing instrument by which the ice is cut into rectangular shape. Fig. 2 is a side view of the handle and a portion of the blade shown in Fig. 1.

' Fig. 3 represents a side view and Fig. t an end view of the end portion of the device shown in Fig. 1. Fig. 5 represents a side view of a straight ice severing instrument which ispreferably used in severing the cakes horizontally from the main block. Fi 6 represents a large block of,ice, in which the small rectangular pieces, which are adapted to be formed with my severing instrument, are indicated in part by dotted lines.

Like parts are referred to by the same reference figures throughout the several views.

It is a well'i'mown fact that when ice has been packed away in an ice house fora considerable length of time and subjected to a low temperature, that the several blocks of which it is originally composed, congeal to form substantially a solid-block of ice, and that preparatory to delivering the ice to the trade, it becomes necessary to subdivide the block thus congealed into a plurality of 1 represents acake of ice, asth'e original 0 parts are congealed together in an ice house. 2, 2, represent a series of cakes as they are Specification of Letters Patent.

severed into uniform rectangular pieces preparatory to being delivered to the trade.

3 represents my angular severing instrument, by which the vertical cuts 4 and 5 are simultaneously formed.

6- represents the severing instrument in position for use.

The instrument '3 comprises the blade 7, which is formed inline with the handle and the blade 8, which is formed at right angles thereto. It will nowbe understood that when the instrument 8 is in the position shown in Fig. 6, the blade 7 is adapted to produce the vertical cut 4, while the blade 8 is adapt edto produce the vertical cut 5.

The blades 7 and 8 are preferably formed of metal of high resistance, whereby as a current of electricity is passed through them, they become heated to a high temperature, and when thus heated and placed upon the ice, the ice will be melted and severed thereby, as indicated in Fig. 6. An electric current is conducted to the severing blades 7 and 8 from an electric generator 9, through the electric conductor 10, switch member 11 and conductor 12, when. a'returncurrent is conducted from'the blades 7 and 8, through the conductors 13 and 1 1. It will of course be understood that the conductors are preferably insulated to prevent the liability of injury by contact therewith and that the conductor 13 is preferably of a low resistance, whereby the return current will freely pass through the same without heating it. By thus forming the blades of the severing instrument at an angle to each other, as shown, two sides of the blocks of ice are simultaneously formed at right angles to each (other, whereby it becomes comparatively easy to form all of the cakes of ice of substantially uniform sizes and in the desired rectangular shape, as indicated in Fig. 6. When the vertical cuts 4 and 5 have been thus formed by passing the severing instrument vertically through the block 1, the horizontal cuts 14 may be more readily pro duced by a straight severing blade of the shape shown in Fig. 5. V

15 represents a straight severing blade of similar construction to that shown in Figs. 1 to 4: inclusive and the same is in like manthrough the electric conductors'16 and 17.

i 18 represents an insulating coveiglig -filhich the electric conductors are shielded from contact with the severing blades.

Having thus described my invention, What ll claim as new, and desire to secure by Let ters Patent, is-

In a device for severing ice by electrically generated heat, an angular severing blade of high resistance, an electric conductor
