G. W. MASON REFRIGERATOR CABINET Original Filed May 8. 1926 Patented July 1, 1930 UNITED STATES GEORGE w. mason, or DETROIT, MICHIGAN, ASSIGNOR To coPnLAnD PRODUCTS, Inc, or DETROIT, MICHIGAN, A CORPORATION or MICHIGAN REFRIGERATOR CABINET Application filed May 8, 1926, Serial No. 107,578. Renewed May 5, 1930.

My invention relates to refrigerator cabinets which are cooled by the evaporation of a liquid refrigerant or like process and particularly to. cabinets in which refr gerating machines are installed and built as a unit.

The combination of a refrigerator cabinet and refrigerating machine is not new; however, in existing constructions of this nature the refrigerating unit is not as easily detachable or accessible for adjustment and repairs as it should be.

The objects of this invention are to combine a refrigerator cabinet and refrigerating unit in such a mannerthat the refrigerating unit which includes the motor, compressor, condensing coils and expansion coils and their connections, may be quickly and easily removed in its entirety from the refrigera tor cabinet, and replaced by another like .unit when it is necessary to adjust, repair or replace the old refrigerating unit, and thus provide for the continuous and uninterrupted use of the refrigerator.

With these and other objectsin view, my invention consists in the arrangement, combination and construction of the various parts of my improved device as described in the specification, claimed in my claims and shown in the accompanying drawing, in

which:

Fig. 1 is a vertical section of arefrigerator cabinet, showing the refrigerating unit installed and in position for operation.

.Fig. 2 is a cross section of the cabinet taken on line 22 of Fig. 1.

Fig. 3 shows a modification of mydevice for supporting the expansion coil of the refriIgerating unit within the cabinet. 7

have shown in Fig. 1 a cabinet having conventionally insulated walls 1 and a removable cover 2.

The refrigerating machine or unit illustrated, is of the conventional type employing the compressor 3 driven by the motor 4 to deliver the refrigerant to the condenser 5 which is cooled by the atmosphere. The refrigerant is delivered from the condenser 5 by the pipe 6 to the expansion coil 7 and 50 is there ga'sifiedand then delivered to the compressor 3 by the pipe 8. The motor 5, the compressor 3 and the condensing coil 5 are all mounted upon and supported by the base 9,-the expansion'coil 7 being attached thereto. The base 9 is constructed to fit within the walls 1 of the cabinet, and is supported therein by angle brackets 10 which are attached to the inner sides of walls 1 as shown. The inner space of the cabinet is divided into an upper and a lower compartment by an insulated transverse partition 11 which completely separates the lower or cooling compartment from the upper comp artment which contains the motor, compressor and condensing coils of the refrigerating unit. The expansion coil 7 of the re frigerating unit is positioned below the transverse partition 11 and within the cooling compartment, and is supported therein by the brackets 12, the said brackets being pivotally attached to the underside of the partition -11 and adapted to swing into contact with, and support expansion coil 7 or to swing away from expansion coil 7, as indicated by the dotted lines, and so release said expansion coil 7 for removal. The partition 11 is cut away in the center to provide a circular opening 13 of sufiicient size to permit the insertion of expansion coil 7,

there being provided in one side of said opening, slots or channels, as indicated by numeral 14, in Fig. 2, of suflicient size to permit the passage of pipes 6 and 8. A removable plug or cover 15 with overlapping upper edges, is provided to fill and completely close the opening 13 in partition 11 and will, when in place, prevent any circulation of air currents between the upper and lower compartments of the cabinet. The

pipes 6 and 8, when in place in the channel 14, may be packed with any suitable pack- ,ing material to prevent the passage of air currents through the partition 11.

In Fig. 2 I have shown a plan view of the upper side of partition 11, taken on line 22 of Fig. 1.

In Fig. 3 I have shown expansion coil 7 supported by an open-work metal partition 16 which is so constructed as not to interfere with the flow of air currents in the replace the refrigeratlng unit, the cover 2 I of the cabinet may be removed, and the cover 15 in opening 13 of the partition 11, may be removed, the brackets 12 swun back from contact with the expansion coil 1 and the entire refri crating unit mountedupon the base 9 and including the expansion coil 7 may be lifted out of the cabinet, thereby obtaining access to any and all of its parts, and the whole may be at once replaced b another unit of like kind, if that is desire or the cover 15 replaced without inserting another refrigerating unit, thus conserving the cold in the cabinet. In some cabinet constructions it would be possible to use the same by the insertion of me after the unit had been removed.

It will be obvious that various changes may be made in the arrangement, combination and construction of the various parts of my improved device without departing from the sp rit of my invention, and it is my intention to cover by my claims such changes as may be reasonably included within the scope thereof.

What I claim is: a

1. The combination of a'refrigerator cabinet having an insulated, apertured horizon- GEORGE W. MASON.

tal partition therein,-an expansion chamber insertible through. said aperture, support members on the vertical walls of the cabinet above said partition, a base mounted on said support members, a motor, compressor and condenser mounted on said base, connections through the aperture in said partition joining the expansion chamber to the compressor and condenser and means for removably closing said aperture,

2. In a refrigerator cabinet,.the combination of the side walls thereof, an insulated horizontal partition havin an opening therein positioned between sa1d walls, a base positioned horizontally above said partition and removably attached to the side walls of sa1d cabinet, a motor, a compressor and condenser mounted upon said base, an ex ansion chamber suspended beneath said ase and insertible through the opening in said partition, pipes extending through said partltion for connecting said expansion chamber with said compressor and said condenser, hooks pivotally attached to the under side of said partition for supporting said expansion chamber, and a removable closure for sa1d o ening-in said partition.
