T0 aZZ whom it may concern:

Beit known that I, ADOLFO DE CLAIRMONT, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The primal object of this invention .is a rareiied-air space in double-walled structures to greatly retard the passage of heat and cold. 1 In refrigeratorconstruction a saving of about fifty per cent.` of ice results, which is of material advantage.

heating, and in warm weather the house or building is rendered `cooler than would be possible if no obstacle were interposed to the penetration of heat-rays. Refrigerator-cars and like cold-storage carriers are enabled to have the storage capacity for provisions increased compared with similar transporting structures of like size as generally provided. Less ice being required, the weight of the refrigerators is diminished. Hence a saving of energy and propulsive power results. The space between the walls must be hermetically sealed, and the air isV exhausted therefrom to a practicable degree by means of a pump or other contrivance.

While the vital feature of a rarelied atmosphere in the space of hollow walls is paramount, yet the invention contemplates the novel structural features which hereinafter will be more fully described and claimed and which are illustrated in the annexed drawings, in whichl Figure l is a perspective view of a refrigerator embodying the invention, a portion of one of the sides being broken away. Fig. 2 is a plan section. Fig. 3 is a`detail view showing more clearly the hinge connection between a door and a side of the refrigerator, whereby communication is established between these par-ts. Fig. 4 is a section about on the line X X of Fig. 3. Fig. 5 is adetail view showing the valve-controlled port between the spacesof adjacent walls.

In house and like con-` struction fuel is saved in cold weather for Fig. 6` is a view of the parts shown in Fig. 4 with the door thrown open, so as to bring the passages of the hinge members into register. Fig. 7 is a perspective view of a hollow glass panel or light. Fig. 8 is a section of the saidV 55 panel.

Corresponding and like parts are referred 4to in the following description and indicated in all the views of the drawings by the same reference characters.

While the invention is illustrated in connection with a refrigerator, it is to be understood that it is designed for general use in connection with structures of any kind having hollow or double walls.

The refrigerator shown is of the type commonly employed for domestic purposes, its top, front, back, bottom, and sides being hollow and access being had thereto by means of the door l, leading to the provision-cham- 7o ber, and the door 2, opening into the ice-compartment. These doors are likewise hollow. The space inclosed between the several walls of the sides and doors of the refrigerator is hermetically sealed, and the air is exhausted 7 5 therefrom by means of a valved nipple or pipe, such as commonly employed in pneumatic devices, the valve opening outward instead of inward. For convenience in exhausting the air from the several parts of the re- 8o frigerator or structure a single nipple or pipe 3 is provided and conveniently located, being applied to the back of the refrigerator in the present instance. The top, bottom, and sides have communication with the back, and the front may be in communication with any one of the sides. Valves 4, of any design or make, are employed for controlling communication between the several air-spaces of the structure, so that after the air has been exhausted 9o the several walls lnay be isolated, thereby preventing the admission of air into the spaces of all the walls should a defect or leak exist in any one of the walls. The hollow spaces of the doors l and 2 are in communication g 5 with the hollow spaces of the walls to which they are attached through the hinges, which are formed with passages. Obviously within the purview of the invention any means may be provided which will establish communicaroo tion between the doors and the parts to which they are hinged. The hinges are preferred,

since they obviate the necessity of providing independent means for establishing communication between the doors and part to which they are attached. The hinge member 5 is provided with the pintle 6, and a passage 7 is formed therein. The` hinge member 8 is formed with theA sleeve 9, which fits over the pintle 6 and has a passage l0, which is in communication with the air-space of the part to which the member 8 is attached. NVhen the hinge members are extended, as shown in Figs. 3 and 4, the passages 7 and 10 are out of register and communication between the space of the door and the space of the part to which the door is hinged is interrupted.'

When the door is thrown open to the limit of its movement, asindicated in Fig. 6, the passages 7 and lO are brought in register and communication between the door and the part Vthe same time.

to which the door is hinged is established. It seldom happens in ordinary usage that the door is thrown back against the part to which it is hinged. Hence normally communication between the door and part to which the door is hinged is cut off. Vhen it is required to exhaust the airfrom the walls of the refrigerator, the valves 4 are opened and the doors are thrown back to the limit of their movement, thereby admitting of exhaustion of the air from all parts of the refrigerator at one and After the air has been exhausted the several spaces of the walls and doors are isolated by closing the valves 4 and by closing or partly closing the doors. The ends of the passages 7 and 10 bordering upon the hinge-joint are extremely narrow. Hence a slight movement of the door suffices to throw the passages 7 and IO out of register. The pintle 6 being tapering and the sleeve 9 of a corresponding taper and the parts iitted by a ground joint, leakage at the joint between the hinge members is obviated.

The door l, leadinginto the provision-chamber, is provided with a glass panel or light l1, which is hollow, the air being exhausted from thespace. Thispanelorlightmaybeapplied to any side of the refrigerator or may be used in structures generally and is admirably adapted for passenger-cars and buildings. By having the air exhausted from the space the vision is not obstructed and the presence 6o of the brace is not perceptible. Y

I-Iaving thus described the invention, what is claimed as new is l. In a structure having hollow walls from which the air is adapted to be exhausted, a 65 valvecontrolled com munication between said walls for isolating the same after the vacuum has been created, substantially as and for the purpose set forth.

2. A refrigerator or like structure having 7o hollow walls from which air is adapted to be exhausted by application of a pump to a side or wall of the structure, and valve-controlled communications between the spaces of the several walls to admit of each being isolated 75 after exhaustion of the air, substantially as set forth.

3. In a structure having a hollow wall and ahollow door, a hinge connection between the door and wall, and hinge members having 8,0

passages in comm unication with,respectively, the wall and the door, said passages being normally out of register to interruptcommunication betweenv the hollow spaces of the wall and door and adapted to be brought into co- 85 incident relation by throwing the door open to the limit of its movement, substantially as set forth.

4. A hollow glass panel or window-light having the air exhausted therefrom and hav- 9o ing a transparent brace attached at its ends to opposite walls of said hollow glass panel, substantially as set forth.`

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