- 8 Claims. (Cl. 62108.5)

My invention relates to liquid congealing apparatus and particularly to a grid structure for forming ice cells suitable for table use.

It is an object of my invention to provide an improved flexible grid structure for congealing liquids for table use.

It is another object of my invention to provide improved liquid congealing apparatus from which congealed liquid is readily removable.

These and other objects are effected by my invention, as will be apparent from the follow- I ing description and claims taken in connection with the accompanying drawing, forminga part of this application, in which:

Fig. l is a top view of my improved liquid congealing apparatus and shows my improved grid structure disposed in a liquid containing pan;

Fig. 2 is a side elevational view of the liquid congealing apparatus; and,

t Fig. 3 is a perspective view of the grid strucure.

Referring specifically to the drawing for. a detailed description of my invention, numeral ll designates a liquid containing panin which a grid structure, generally designated at I2, is disposed. I'he grid structure l2, preferably formed of stainless steel, embodies a longitudinal wall l3 and a .series of spaced transverse .walls It extending from opposite sides of the longitudinal wall it to form, with the pan ll, four corner cells l5 and a series of intermediate cells is disposed in rows between the corner cells. The cells It and it provide cubes of a size suitable for table use.

lhe longitudinal wall I3 is formed of two sheets of flexible metal Ill and it, which are fastened by clips l9 at the extremities thereof, and are preferably, though not necessarily, fastened by any suitable means, such as weldingat 2i, to prevent spreading of the sheets ll and It. The transverse walls I I are formed by bending the sheets I l and It! at right angles, then doubling the sheets at 22 back to the plane of the longitudinal wall it, then again bending the sheets at right angles to form the next section of the longitudinal wall. The transverse walls it, are therefore, formed of two contiguous sheets of metal 23 and 24, doubled at 22.

As is apparent from the drawing, the transverse walls it on opposite sides of the longitudinal wall it are staggered with respect to each other. By staggeringthe transverse walls It, greater flexibility of the grid structure I! is obtained, thus facilitating removal of the frozen liquid from the grid structure l2.

Handles 25 are plvotally fastened to the extremities of the longitudinal wall It] and, when rotated outwardly, bear on the pan member it to raise the grid it and break the ice bond between the congealed liquid and the pan ll so that the grid structure I? with the frozen liquid therein is readily removed from the pan. The

handles 25 are then used to impart flexing movement to the grid to facilitate removal of the frozen liquid therefrom. Such a construction is fully described and claimed n my copending applcation, Serial No. 17,220, filed April 19, 1935 for Liquid congealing-apparatus, and assigned to the assignee of the present invention.

The transverse walls are also preferably fastened together, such as by welding at 26 adjacent the bottom of each transverse wall member, to impart stiffness to the grid structure l2 in a direction upwardly of the pan it, while not af footing the flexibility of the grid structure l2 in the remaining directions. Whenthe handles 25 are rotated, the grid structure It is, therefore, raised an equal distance along its entire length so that the bond between the congealed liquid and the pan is readily broken. The stiffening of the flexible grid structure by fastening the transverse double walls adjacent the bottom thereof is fully described and claimed in my copending application, Serial No. 110,611, filed February 10. 1934, forlce freezing device and assigned to the assignee'of the present application.

From. the foregoing it will be apparent that I 'have provided improved ice congealing apparatus from which congealed liquid is readily removed,

' and have also provided an improved flexible metal grid structure from which congealed liquid is readily obtainable.

While I have shown my invention in but one form, it will be obvious to those skilled in theart that it is not so limited, but is susceptible of various changes and modifications without departing from the spirit thereof, and I desire, therefore, that only such limitations shall be placed thereupon as are imposed by the prior art or as are specifically set forth in the appended claims.

What I claim is:

3. A receptacle for producing frozen ice cells comprising a pan and a flexible grid structure therefor dividing the pan into four corner cells and a series of intermediate cells disposed in rows and extending between the comer cells, said grid structure embodying a longitudinal wall formed of two sheets of metal disposed contiguous to each other and fastened together and also embodying a series of spaced walls extending transversely from opposite sides of said longitudinal wall, thetransverse walls-0n one side of the longitudinal wall being staggered with respect to the transverse walls on the other side and a series of intermediate cells disposed in rows and extending between said corner cells, said grid structure embodying a longitudinal wall formed of two sheets of metal and also embodying a plurality of spaced walls extending transversely from opposite sides of said longitudinal wall and formed of two sheets of metal fastened together near the bottom thereof-to prevent substantial flexing of the grid structure in a direction upwardly of the pan, said transverse walls on one side of ,the longitudinal wall being staggered with respect to the transverse walls on the other side of the longitudinal wall.

5. A receptacle for producing frozen ice cells comprising a pan and a flexible grid structure therefor dividing said pan into four corner cells the transverse walls on the-other side of the longitudinal wall, and means disposed on the grid structure for breaking the ice bond between the ice cells and the pan to facilitate removal of the grid structure from the pan and for thereafter imparting flexing movement to the grid structure to facilitate removal of the ice cell therefrom.
