This invention relates to new and useful improvements in refrigerators and more particularly to a supporting plate or pad which is used for supporting the ice and also used as an insulation. 4

One of. the objects of our invention is the provision of a plate or. ad adapted to be placed in the ice receptac e of a refrigerator for supporting the ice and which is provided with a lurality of openings extending through t e plate to provide for a thorough circulation ofair around the ice and also provide. an insulation plate which will prevent too rapid melting of the ice.

Another object of our invention is the provision of an insulation plate for refri erators formed with transverse openings an which is adapted for use not only in supporting the ice within the ice chamber of a refri erator, but is also ada ted to be positione sidesand top 0 the ice if so desired, to provide proper insulation which will reduce to a minimum the melting of the ice.

A further object of our invention is the provision of an insulation plate for refrigerators which includes s aced parallel metal lates, having arrange between them asstos or other suitable filling material of a similar nature, said plates being connected by tubular rivets which will permit circulation of air through the plates and the metal j walls will prevent rapid deterioration of the filling between them.

With the above and otherfobjects in view the invention consists in the'novel features of construction, the combination and arrangement of parts hereinafter more full set forth, pointed out in the claimsand s own in the accom anying drawings wherein:

Figure 1 1s a transverse sectional view taken through the ice compartment of a re-' f?) frigerator, illustrating the application of our improved plate. p

igure is an elevatlonof one ed e of a plate illustrating a modified form t ereof, parts thereof being broken away and illustrated incross section. 1 a

Referrin more particularly to the drawing, it will note that we have shown, for the purpose of illustrating our Invention at the only, a portion of a refrigerator which includes the body 1 havin a top portion 2 formed with an. opening %or receiving there through the ice for the chamber, 3, chamber 3 forming the usual ice compartment for the refrigerator. The opening in the top wall -2 is normally closed by means of a, removablecover 4.,

The walls ofthe chamber 3 may be formed of any thickness, but are preferably of light weight as shown in the drawings and are provided adjacent their up er ends ';with suitable openings 5.to provi evfor the thorough circulation of the air through the ice position relative tothe filler, tubular rivets 10 are used for connecting the two side plates,

outer face of the plates 8, so as to securely retain the plates against spreading movemg plate, it will provide insulation for the ice 'saidrivets having their ends upset onto the and at the same time provide for thorough circulation of the air around the ice, so that the maximum benefit maybe derived from the ice in the chamber 3. It will be noted that in Figure 1 the use of the plates as'insulation along the side walls of the chamber has been displosed; this aidsin preventing the too pid melting ofthe ice and if found dmire one of the plates may be placed on top of the ice so as to entirely-enclose the same in an insulated chamber. t

With the use of our improved plates as illustrated, it will be noted that by using the tubular rivets 10 as disclosed, a plurality of vent openings are formed which also provide .for

a thorou hdrainage of the dri pings from the ice an reduce to a minimum t e deteriora a from the spirit 0 tion of the filling 9 and at the same time provide for a thorough circulation of air.

In the operation, assuming that ice is placed in the cavity formed by the various walls 7, air coming in contact therewith will become cold and will drop to the bottom, displacing the relatively warmer air, which will rise. This cold air will fill the chamber or element 3 to the opening 5 and spill over the sides. The air outside of the chamber 3 will thus be cooled b conduction and aid in cooling the air which is past through the openings 5.

In Figure 2 we have illustrated a slightly modified form of the invention wherein the plates 8' are illustrated in corrugated form with the asbestos filler 9 placed between the lates and secured by means of the rivets 10. this form of the invention it is unnecessary to use tubular rivets as the channels in the corrugated plate will provide for the drainage 0 an.

In the showing of Figure 1, it will be aparent that any suitable t pe of drainage may e used for draining the water from the channel 3.

While we have shown and described the preferred embodiment of our invention, it will be ap arent that slight changes maybe made in t e construction when putting the invention into practice without departing the same or the scope of the ap ended claims. e claim:

1. A pad for refrigerators including spaced metal plates a fibrous filler between said plates and tubular rivets passing through the plates and filler for retaining the plates against movement relative to each other.

2. A pad for refrigerators including spaced metal plates, a filler of asbestos between said plates, and tubular rivets passinglthrough the plates and asbestos filler and aving their ends upset onto the outer faces of the plates for holding said plates against movement relative to each other.

In testimony that we claim the foregoing we have hereunto set our hands at Racine, in the count of Racine and State of Wisconsin.
