PECK, F PORTLAND, OREGON, AND HOWARD BLOOD, OF DETROIT, MICHIGAN REFRIGERATOR CABINET Application filed January 5, 1929. Serial No. 330,520.

Our invention relates to refrigerator cabinets especially adapted for the ice cream trade and it particularly relates to cabinets having a number of distinct compartments with. associated refrigerating apparatus to maintain different temperatures in the. severalcompartments.

The present invention has to do with the structure of the cabinet proper regardless o the "specific refrigerant employed. I

An object of the invention is to provide a cabinet of a neat appearance, one which can be manufactured at reasonable cost and one which has effective provisions, to prevent water being slopped into the compartments when washing the top of the cabinet.

Further it is an object to provide a cabinetwhich contains a double-wall shell lining for the compartment or compartments of the .19 cabinet, in which shell the refrigerating fluid and the cooling coils are located, and in which provision is made effectually to insulate the top of such shell from contact with the lid, the insulation being so attached to 5 the top of the cabinet as to comprise an integral structure therewith, whereby when it is desired .to remove or replace the shells the top with such insulation may be taken off and replaced as a unit. I

Further, it is an objectto provide means whereby the cover or covers for the compartments will eflectively close their compartments without metal-to-metal contact between cover and cabinet top, thereby preventing loss of temperature by conduction I and yet permitting a metallic sheathing for the cover to be used. I

Other objects will in part be obvious and in part be pointed out hereinafter.

Tothe-attainmentof the aforesaid objects and ends, our invention consists-in the novel details of construction and in the combination, connection and arrangement of parts, hereinafter more fully described and then pointed out in the claims.

In the drawings:

Figure 1 is a side elevation of a refrigera tor cabinet embodying our invention, parts being broken away and shown in section.

Figure 2 is a plan of a portion thereof,

parts being broken away and parts being how the refrigerator pipes are passed into and from the cabinet.

Figure 5 is an enlarged detail section and parts being shown in section to illustrate through an upper portion of the cabinet showing the, top unit lifted from the remainder of the cabinet body and showing the cover unit lifted from the top unit.

Figure 6 is a detail horizontal section on the line 6-6 on Figurel.

Figure 7 shows adetail section of the lidhinge construction.

In the drawings in which like numerals and letters of reference indicate like parts in all of the figures, 1 designates an angle iron frame, the sides, ends and bottom of which are covered with galvanized steel plates 2 held in position by corner angles 3 and screws 4 as indicated in detail in Figure 6.

Within the frame and separated from the plates 2 by a suitable thickness of paper 6 is the cork wall 5 which functions as the principal heat insulator, thiswall being chambered to provide the compartments 7 and 8 (two being shown in, the embodiment illustrated). a v p In each of these compartments there is located a double-wall refrigerant container 9 and 10, the depth of which depends upon the temperature to be produced in the particular compartment containing the vessels 9 and 10. lVhere the temperature is to be lowest the vessel 9 may extend to the bottom of the compartment. Where the vessel 10 does not e2;- tend to the bottom. of the compartments 1t rests on the upper flange 11a of a deep pan located withinthe containers 9 and 10 and Y extend to the outside of the refrigerator cab-- of ring-like form and arranged to fit at 17 w into the top groove 17 ;2/ of the container 9 or 10 as the case may be.

The rubber compound bands 17 have metal threaded sockets 18 molded into the same, to which, by screws 20, angles 19are secured, the angles 19 being preferably permanently secured to the top plate 24. The top plate 24 is preferably formed of galvanized steel and has an outer annular flange 25 bent downwardly as best shown in Figure 5.

The bands 17 have their upper surfaces grooved as at 21 for the reception of the strips or bands 22 of suitable rubber compound which fit the grooves 21 and project upwardly therefrom a suitable distance as best shown in Figure 5, and these strips or hands 22 have roo'ves or recesses 23 ontheir outer surfaces j ust above the top surface of the bands 17.

26 designates a sheathing of Monel metal which is bent at 27 over the inner edge of the top plate 24 and is extended down over the flange25 and bent back under the same as at 28, as clearly shown in Figure 5 of the drawings. I

' The cover is secured to the upper angle irons of the frame 1 by means of screws 29 with interposed Monel washers 30.

The covers for the compartments may be made in single bodies or in sections if desired. When made in sections the sections are preferably hinged together as will hereinafter more clearly appear.

By reference particularly to Figure 5 it will be observed that the covers each comprise a frame 31 of rubber composition in which is contained the cork filler 32 wrapped in paper 33. The bottom of the frame 31 is sheathed with a plate 35 of Monel metal secured in place by screws 36 and threaded metal sockets 34, the latter being molded in the cover frame 31. The bottom plate 35 has its edges upturned as at 36 and counter sunk into the frame 31' so that its outer inclined faceanay be flush with the inclined face 37 of the frame 31, see Figure 5.

The cover frame 31 has a flange 38 adapted to fit within the confines of the strip 22 when the cover is in place.

Molded in the cover frame 31 is a metallic member consisting of a plate 39, an anchoring portion 40 molded in the frame 31, the plate 39 being countersunk in the cover frame so that its upper face lies flush with the extreme upper face of the cover frame.

Over the cover frame, the cork 32 and the plate 39 is extended a sheathing 41 of Monel metal, the margins of which are bent over the projecting portion of the plate 39 as at 42, to cover the said projecting portion.

It will be seen by reference to Figures 1 and 5 that when the lid is closed the projecting Monel metal covered nortion of the plate 39 will extend above the strips 22 and rest upon the same with the frame 31 confined by the strips 22, there being, however, no contact between the cover frame 31 and the band 17 in order that a tight seal may be effected between the

parts

42 and 22 when the cover is in place.

\Vhen the cover is made of two parts hinged together the construction disclosed in Figure 7 is preferably employed. By reference to this figure it will 'be seen that the Monel metal top sheets 41 are formed into hingeelements 43 and vertical plates 44 extend downwardly from the hinge elements as a part thereof or integral therewith and are secured by screws 45 passing into threaded socket members 34 molded in the cover frames 31. A suitable gasket 46 is also secured to one of the cover frames 31 and is adapted to engage the opposing cover frame 31 when the cover.

is closed as indicated in Figure 7 to efi'ect an air-tight joint.

While we have specified the cover and

top sheathings

41 and 26 respectively as of Monel metal, it is obvious that any other suitable metal which will not corrode may be employed.

\Vhen reference is made in the claims to heat insulating and heat non-conducting material we wish it understood that these are relative terms and are not to be construed as absolute.

While we have disclosed as a preferred embodiment of the invention a two temperature cabinet, it is obvious that the invention is applicable as well to a single temperature cabinet, a cabinet of one compartment or a skilled in the art.
