REFRIGERATOR.

Application filed May 22, 1924. Serial No. 715,045.

\ f To all whom it may concern:

Be it .known that I, LLOYD G. Cornrmn,

a citizen of the United States, residing at Flint in the county of Genesee and State of Michigan, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to a refrigerator,

. and more particularly pertains to the means for securing and floating. the inner shell within the outershell.

The object of the present invention is to support the inner shell in spaced relation with respect to theside walls of the outer shell largely by means carried by the front of the outer shell. In this construction the inner shell is first correctly positioned so that the door openings in the front of the outer shell will register with the several chambers in the inner shell after which the inner shell may be clamped to the outer shell without the use of aback plate.

In the drawings:

Fig. 1 is a perspective view of the outer shell partially broken away to show the supporting means.

Fig. 2 is a horizontal section through the refrigerator showing the inner shell and ice-chamber secured to the outer shell.

Fig. 3 is a section on the line 3-3 of Fig. 2.

Fig. 4 is a section on the line 4-4 of Fi 2.

Fig. 5 is a detail of the crimped union of the clamping tension straps.

Fig. 6 is a detailed section showing a modified form of construction in which the outer shell is formed of cast stone.

This refrigerator comprises an outer shell (1, which may be made of wood or other fibrous material, or it may be made of cast material as shown in Fig. 4. Referring to the preferred form of construction in which the outer shell is formed of fibrous material I provide the front of the outer shell with one or more openings b and with a lar e opening at the rear. Secured to the insi e of the front wall of the outer shell are a plurality of angle bars c which are positioned around the openings b. The inner shell d which is preferably moulded of an oxychloride cement, is telescoped into the outer shell and is provided with one or more openings in the front adapted to register with the openings 6 in the front wall of the outer shell. This will'form a passageway 'of the outer shell.

from the outside to the interior of the inner shell so that access may be had to the same.

. The inner shell abuts the inside of the front wall of the outer shell and fits within the angle bars 0 as clearly shown in Figs. 2 and 3. This supports the inner shell in spaced relation with the top, side and bottom walls The angles are provided with a plurality of slots f in which the straps g are anchored the, said straps passed around the body of the inner shell and drawn taut by a suitable tool. The ends of the strap are then secured together as at h by crimping a tie over the. same and thereby securely clamping the inner shell to the supports carried by the members may be passed about the inner shell in as many places as is desirable so that the inner shell will be securely held in place.

One of the openings 7) in the outer shell I forms the opening for which access is bad to the ice-chamber z'. Surrounding this opening for the ice-chamber I saw out grooves j in the front wall of the ice-chamber. The lining of the ice chamber is preferably formed of sheet metal and open at the front, the edges of which are fitted into these grooves and the straps is anchored to the angles 0 are passed around the ice-chamber lining and drawn taut and clamped together for clamping the ice-chamber to the front wall of the outer shell. However, the inner shell can be constructed entirely of'cast stone as shown in my co-pending application, Serial No. 647,603, in which the food chambers and the ice chambers are of cast material. This same securing means can be utilized for clamping the inner shell to the outer shell and holding the same in spaced relation with the four side wallsof the outer shell.

Fig. 6 shows a modified construction in which the outer shell is of cast stone and a wood frame m is cast-united to the outer shell, as shown in my co-pending ap lication, Serial No. 686,883. This wood rame is provided with the groove n in which the inner shell is fitted, the angle bar being secured to the frame m and the straps g anchored to said angle bars for clamping the inner shell to the outer shell. 7

In Fig. 4 is shown the means by which the back plate is secured both to the inner shell andt e outer shell for supporting the rear portion of the inner shell,

vopenings,

thereby more rigidly securin the inner shell to said outer shell. Fi rous strips 7' are cast-united with the inner shell by means of the fastening devices 8, which in this case are shown as large headed nails, which are partly driven into the wood strip,

the means being embedded in the cement,

thereby securely anchoring or keying the strip to the moulded inner shell. As many of these stripsmay be used as is desired and the back plate is secured to the strips by means of nails, screws, or other suitable fastening devices as at t. The back plate is then secured to the outer shell by fastening devices a. Thus the inner shell is su ported in spaced relation with respect to e outer shell at the front by the supporting angle bars 0. The tension members 9 clamp the inner shell against the front wall of the outer shell. The back plate supports the rear portion of the inner shell and relieves the said shell from some of the strain, thereby functioning as an auxiliary supporting means.

What I claim is: p

1. In a refrigerator, the combination of an outer shell provided with an opening and at the front with one or more door openings, an inner shell provided at the front with an opening and telescoping into the outer shell and clamped to the front of the outer shell in spaced relation with some of the walls, and tension bands for effecting such clamping.

2. In a refrigerator, the combination of an outer shell provided with an opening and at the front with one or more door and a moulded inner shell provided at the front with an opening and telescoping into the outer shell and hun from the front of the outer shell in spaced relation with some of the walls.

3. In a refrigerator, the combination of an outer shell provided with an opening and at the front with one or more door openings, an inner moulded shell provided at the front with an opening and telescoping into the outer shell, and tension means for securing the inner shell to the front of the outer shell.

4. In a refrigerator, the combination of an outer shell provided with an opening and at the front with one or more door openin s, an inner moulded shell provided at t- 1e front with an opening and telescoping into the outer shell, angle bars secured to the front of the outer shell and surrounding the door openings for supporting the inner shell in spaced relation with respect to some of the walls of the outer shell, and means for securing the inner shell to said supporting angle bars.

5. lo a refrigerator, the combination of an outer shell provided with an opening and at the front with one or more door openings, a moulded inner shell provided at the front with an opening and telescoping into the outer shell, angle bars secured to the front of the outer shell for supporting the forward end of the inner shell, and means for clamping the inner shell to the front of the outer shell.

6. In a refrigerator, the combination of an outer shell provided with an opening and at the front with one or more door openings, an inner ,shell provided at the front with an opening and telescoping into the outer shell, angle bars secured to the front of the outer shell for supporting the forward end of the inner shell, and straps anchored to the supporting angle bars and passed around body of the inner shell, the said straps drawn taut and secured together 'in such taut position to clamp the inner shell to the front of the outer shell for floating the same in such spaced relation with res opt to some of the walls of the outer she I.

In testimony whereof I have affixed my signature.

LLOYD G. COPEMAN.
