To all whom it mwy concern:

Be it known that I, Anson H. Caoss, of l lV'inthrop, in the county of Sn doll: and State 5 ofMassachusetts, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

Clhis invention relates to refrigerators or cold storage receptacles, the walls of which are rendered non-conductors of heat by Walls. from which chambers,'air is exhausted to form a Vacuum space practically surrounding the storage chamber and preventing heat from being conducted through the walls of the receptacle so that a low temperature may be maintained in the THEE.- tacle with a minimum consumption of ice.

Heretofore it has been proposed to pro vide a vacuum space. or chamber surrounding a storage space, the vacuum space being practically continuous so that, in the event. of leakage of air into the vacuum space at any-pointin the Wall of the refrigerator, the entire vacuum will be destroyed.

My invention has for its object to mini mize the loss or impairment of the vacuum by leakage at any given point in the wall of a refrigerator of the -lnss to which. my invcntion relates, and to this end it consists in a refrigerator comprising hollow Wall sections, each ha ing a space from which air. is adapted to be exhausted, the spaces of the sections being independent of each other so one point, in the refrigerator Wall, the disturbance of the vacuum will be confined to the section in which the leakage occurs, the

Of the accompanymndrawings forming a part of this specification, Figure 1 represents a front. elevation of a refrigerator ein mdy ing my invention. Fig. 2 represents a sec tion on the line 2-2 of Fig. 1. Fig. 3 represents a section on the 1 inc 3--3 of Fig. 2.

The same numerals of reference indicate the same parts in all the figures.

space 12 of each sect-ion is adapted to be independently exhausted of air and hermeticso thanv leakage of air into any section will not affect the vacuum in any other section or sections. Each section is exhausted anysuitalolc means to form a vacuum, each, ection being hc1:metically the exhaustion of the all, As here shown, each of the side walls of the receptacle composed of a single section, namely, a norlzontal bottom section l3, \'crti cal side sections l-l. and a horizontal top sec tion 15. These sections may be of any s; t able material or materials, and arr-f suitably connected to torn: a storage chan'lbcr of substantially air-tight construction. A's here shown, the bottom and side sections are proaided with beveled edges 16 which are prefe aibly-the sides of flanges formed on said sectienaes shown in Figs.- 2 and 3, "said flanges able packing" strips may heinterposed between the beveled edges 16 to term air-tight joints. The bottom section 13 is shown as provided with dowtmmrdly projecting legs 18 having casters 19!);

preferably hinged to one oi" the side sections so that it. constitutes a top or cover which may he raised to permit access to the interior of the receptacle. The sections may be provided internally with stay-bolts 19 to pro-- vent the sides of the sections from being forced together by atmospheric pressure. The interior of the receptacle may be provided with suitable "shelves 20 and with an ice receptacle 21, here shown as a pan, (lo-'90 by the upper shelves and provided with a Waste pipe 22 adapted to conduct away the water resulting from the melting of the ice, said Waste pipe leading tachahly supported to a trapped outlet in the bottom section 13.

Suitable ventilating means may bcemployed to ventilate the interior of the receptacle if desired. The sections may he of any suital'ilc material, for example. each section may be cast from aluminum or other suitable metal.

lt is obvious that the number of sections forming the walls of the storage receptacle may be greater than that here shown, and l do not limit. myself to a construction in which each side Wall is made as a single 10a part.

The air may be exhausted from the sections in any suitable way and any suitable connected by pelts 1?. Suit- 75 'lili'e top section 15 is 80 means may be employed for hermetically r ftlllllg each section after the air has been exhausted from it.

The storage chamber may be either port- 5 able or fixed. 't

A cold storage chamber or structure of l any desired size may be made in accordan t with my invention. i

structure embodying my lll\'tlll10l1 as above described, may have an outer casing or an inner casing or lii'iing', or both of wood or other suitable material.

As shown in Fig. 3, the inner walls of the side sections are formed with'intcgral ledges or cars 28 on which the shelves 20 may be removahly supported. This integral struc ture provides a support for the shelves for regulating any internal attachments to be made to the sections, as by nails or screws or other means which might tend to weaken the inner walls of the sections so as to pro duce leaks. As also shown in Fig. 3, the bottom section not only has integral legs 18 I but is formed with. an integrally depressed i portiondl to receive dri )pings or water of condensation. This depression forms an inj tcgral cup 2- from which the drippings or water may be drawn through the medium of i any suitable outlet pipe. The ventilating tubes oi pipes 25 arc also formed integrally with the iunc and outer walls of the sections so that the prc-rncc o'l saitl pipes or i tubeswill not tend to wcaltcn the walls ol" the sections andresult in leakage of air.

I claim:

1. it refrigerator comprising hollow wall sections, cachet which is cast in one piece. and incloscs an indtpcndcnt \tlt'ttlllll cham ber. each section having an air outlet adaptcd to be hermetically sealed, the chambers being exhausted and scaled bclorc the set tions ar assembled, said sections bcitr; provided with internal means for supporting their sides against illll'lOSPllOllC pressure, and

being connected together to form a storage receptacle.

2. A retrlgerator comprising hollow wall sections each of which is an independent vacuum chamber, said sections being operatlvolyyconnectcd to fornra storage receptacle, the lower or bott om section having in tegral legs projecting downward to support the bottom section above the floor.

3. A refrigerator comprising hollow wall sections each of which is an independent vacuum chambeiysaid sections being operatively connected to form a storage rcce taclc, the lower section having an integrally formed depression or cup shape portion to receive drippings or water of condensation.

4. A refrigerator comprising hollow wall sections each of which is an independent vacuum chamber, said sections being operatively connected to form a storage receptacle, the said sections having integral ledges adapted to support removable shelves.

5. A refrigerator comprising hollow wall sections each of which is an independent vacuum cl'iamber, said sections being operatively connected to form a storage romp-- tacle, one of said sections having pipes or tubes extending entirely through it and in tegral with both the inner and outer walls of the said section.

6.. A refrigerator comprising hollow wall sections each of which isan independent -vacuum chamber, said sections being operatively connect-ed to form a storage rcccptaclc, said sections having beveled edges tormcd with integral extensions or'tlangcs whicharc boltcd together outside of thc rc l'rigcrat or.

In testimony whereof I have allixctl. my signature. in presence of two witnesses.
