4 Claims.

This invention relates to refrigerating apparatus and particularlyto the arrangement of a refrigerating element in a refrigerator cabinet.

One of the objects ofthis invention is to provide an improved arrangement of a refrigerating element in a refrigerator cabinet.

A further object of this invention is to arrange a refrigerating element within a refrigerator cabinet in such a manner so that the refrigerant control valves and operating mechanism thereof may be accessible from the exterior of said cabinet. v

A further object is to arrange a refrigerating element within a refrigerator cabinet in such a manner so that the refrigerant valve and operating mechanism thereof are accessible from the exterior of said cabinet, and to arrange said cabinet in such a manner so that said valve and operating mechanism are accessible from the ex- 0 terior of the room or apartment in which said cabinet is located.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accom- 25 panying drawings, wherein a preferred form of the present invention is clearly shown.

In the drawings:

Fig. l is a vertical cross sectional view of a refrigerator cabinet showing the refrigerating 30 element and showing features embodying the present invention;

Fig. 2 is a view of a portion of the apparatus shown in Fig. 1 taken in the direction of the arrow 2-2 of Fig. 1;

Fig. 3 is a view similar to Fig. 2 and showing the closure means for the opening provided in the rear of the cabinet in an open position;

Fig. 4 is a view in cross section of a portion of the refrigerating element forming a part of. the 40 present invention; and

Fig. 5 is a front view in elevation of the apparatus shown in Fig. 4.

Referring to the drawings the numeral designates a refrigerator cabinet provided with a 45 'cooling compartment 21 formed by an inner lining 23. The cabinet also includes suitable insulation 25 disposed between the inner lining 23 and an outer covering 27. A refrigerating ele- 50 ment is disposed within the cooling compartment 21. element may be used for supplying refrigerant to the refrigerating element 30 and for instance a refrigerant circulating element of the type dis- 55 closed in the patent to Harry 3. Hull No. 1,648,-

Any suitable refrigerant circulating 178 issued November 8, 1927. The cabinet also includes the usual opening 38 closed by door 40.

Referring more in detail to the drawings, the refrigerating element 30 may be suspended within the cooling compartment 21 in any suitable manner, and for instance, may be clamped to the inner lining 23 along the rear wall thereof by screws and may be supported at the opposite end of said refrigerating element by means 46. The refrigerating element illustrated includes a container 48 adapted to contain a quantity of liquid refrigerant and includes means in the form .of ducts 50 forming a freezing compartment adapted to receive a plurality of ice making receptacles 53. The container 40 is provided with an end ring which is clamped to the inner lining 23 by an outer ring'57 and the screws 45. Thus the end ring 55 will engage the inner lining 23 on the inner side thereof while the ring 57 will engage the lining 23 of the opposite side thereof while the screws 45 will clamp the ring 55 and 5'7 to said lining to thus support the valve plate end of the refrigerating element to the inner lining 23.

The refrigerating'element 30 is provided with the usual valve plate 60 which is rigidly clamped to the end ring 55 by means of bolts 63. The valve plate 60 is adapted to support the usual float valve mechanism within said container which is removable from said refrigerating element by the removal of the valve plate 60 which may be accomplished by removal of the bolts 63. The valve plate is provided with refrigerant valve connections and 71 on the outer side thereof. The connections 70 provides a connection for a vapor conduit 74 and the connection 71 provides a connection for liquid refrigerant conduit 75. The refrigerant valve connections 70 and 71 are provided with shut ofi valves not shown herein but clearly shown and described in the copending application of Otto M. Summers, Serial No. 266,397 filed March 31, 1928.

The refrigerantconduits 74 and 75 may be received by an opening provided in a wall 82 formed by the room or apartment in which the refrigerator cabinet 20 is located, the conduits leading to the refrigerant circulating element.

According to this invention the refrigerating element 30 is disposed on one side of the lining 23 while the valve plate 60 is accessible from the opposite side thereof. Thus the valve plate 50 extends through an opening formed by the inner lining 23 and terminates between the lining 23 and the outer covering 27. The outer cabinet 20 is located, repairs of the refrigerant 1 covering 27 is provided with an opening 93 adjacent the valve plate 60, which opening is provided with swinging closure means 94. Suitableinsulation 95 such as kapok may be inserted 70 and 71.

From the foregoing description it will be noted that there is provided a refrigerating element. disposed within a refrigerator cabinet in such a manner that the refrigerant valves and operating mechanism therefor are accessible from the complished without entering the. apartment in which the refrigeratorcabinet is located. In order to do this all that is necessary is to pump the refrigerant from the container 48 then remove the conduits from the valve connections. After the'conduits are removed, the valve plate 60 together with the float valve mechanism may be removed, by removing the screws 63, the plate and float then may be withdrawn from the cabinet 20 through opening 93 provided in the rear of the cabinet and through opening 80 provided in the wall 82 which opening 80 may be normally closed by door 99. Also this arrangement is advantageous should there be a leak between the valve plate 60 and ring in which case the gas formed by the liquid refrigerant in the container 48 would not escape-into the cooling compartment 21 which would be undesirable. Since the refrigerant circulating element is disposed.

in the basement or any other room or apartment from the'room or apartment in which the circulating element may be made without entering the apartment in which the cabinet 20 is located.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it. is to be understood that other forms I might be adopted, all coming within the scope of the claims which follow.
