ASSIGNMENTS, TO THE NATIONAL SAME PLACE.
OF BALTIMORE, MARYLAND, ASSIGNOR, BY MESNE REFRIGERATING COMPANY, OF
REFRIGERATOR.
SPECIFICATION forming part of Letters Patent No. 409,035, dated August 13, 1 889. I 7
Application filed February 18,1889- Serial No. 300,263- (No model.) i I 1 skilled in the art to which it appertains to make and use the same.
This invention relates to refrigerators; and
it consists in the novel construction hereinafter described, and set forth in the claim.
Figure 1 is a vertical sectional view of arefrigerator embodying my invention. Fig. 2
is a longitudinal sectional view taken on the line a: a; of Fig. 1, showing the auxiliary chamber attached thereto for containing barreled beer or other spirituous liquors and the means for cutting ofi communication between the main chamber and the said auxi 'ary chamber, the doors being closed; and-Fig. 3 is a similar view showing the doors of the auxiliary chamber open, thereby cutting'oif communication between the main chamber and the auxiliary chamber.
Referring to the drawings, A designates the casing of the refrigerator, which may be made of any suitable material, but preferably, in this instance, of an outer casing 1, of wood, a lining 2, which may be of any suitable dampproof material, but preferably of tarred felt, and an inner lining 3 of zinc or any other noncorrosive material. This casing is divided into two compartments 4 and 5, separated by a rack 6, so as to allow a complete circulation of the air between the two compartments. The lower compartment 4:, which is the cold-air chamber, may be provided with any suitable means for holding articles, but preferably, in thisinstance, with a revoluble table, and the upper compartment or refrigerating-chamher with any refrigerating-receptacle, but
- but'preferably of zinc,
preferably a receptacle such as 7, in which are placed refrigerating-chemicals. This receptacle may be made of any suitable material, and is provided on its upper surface with an inlet 8, through which the chemicals are placed, the said inlet being connects with the pump,
ceptacle through the pipe covered by a cap 9. The bottom is provided with an outlet 10, provided with a similar cap 11.
To one side of the refrigerator, and either upon the interior or exterior, is placed a pump 12, which is operated by means thereto through a pipe 13. In this instance a Water-motor is shown; but, if desired, a motor operated by clock-work, may be employed. Connecting with the pump are two pipes 14 and 15. The pipe 14 is coiled of water fed electricity, or steam around and i-ncloses the receptacle containing the refrigerating-chemicals and enters the same at the point 16, which is preferably-at the top of the side. The pipe 15 connects with the lower side of the receptacle at 17 and as shown.
Having now described the different parts of my device, I will proceed tosh'ow the manner in which it operates. v
A suitable quantity of refrigerating-chemicals is first placed in the receptacle through the inlet 8, and the same 1s mixed with water until brought to the proper consistency. The cap 9 is then screwed on trance of the outside air, which would tend to desired. The pipe 13 is then connected with a suitable water-supply; but, if desired,'the same may be previously attached to a watersupply and provided with a cook 18, which,
when turned, w1ll allow the water to flow to the pump and thus start the same. As soon as the pump operates, the mixture of chemicals and water is rapidly drawn from the re' 15 to the pump, from which point it is forced through the pipe 14 around the exterior of the receptacle and into the receptacle again as the motor operates, this circulation willbe kept up, thereby presenting a constant cold surface to the atmosphere within the refrigerator. After the chemicals have become exhausted, or, in other words, have lost their cooling properties, the mixture is removed by unscrewing the cap 11, when the contents may be readily removed and the receptacle replenished.
The auxiliary chamber consists of a cylintd prevent the en-' at the top. As long exhaust the chemicals more rapidly'than is enters the auxiliary chamber;
drical housing or casing 19, secured to the refrigerator proper and preferably at its back. The walls 20 of this cylinder are made in two sections 21 and 22, and between these sections move sliding semicircular doors 23, which, when pushed out, as shown inFig. 2, meet at the point 24, and thus leave a space 25, through which the cold air from the cold-air, chamber but when it is desired to open the auxiliary chamber for the purpose of placing articles therein or removing them therefrom the doors are slid back, and thus meet at the point '26, thereby effectually preventing the air from the c01d-air chamber escaping or' the warmair from the outside entering.
As before stated, only one form of refrigerator has been shown, which, by preference, 'is cylindrical; but I will have it understood that I do not cbnfine myself or size, nor to any particular materialormaterials in constructing'the same, but may avail myself of those forms and materials that ingly simple of to any particular shape are best adapted to my purpose. It will thus .be seen from the foregoing description that,
form of refrigerator is exceedconstruction, it will be found of the highest efiiciencyand durabilityin use.
although this Having thus fully described my invention,
what I claim as new, and desire to secure by Letters Patent, is
The combination, in a refrigerator, of the cooling-chamber proper, a substantially cylindrical chamber communicating therewith and provided with double walls and a front opening, and the curved doors sliding in said walls, as described, front opening or the communication between the chambers, substantially as set forth.
In testimony that Iclaim the foregoing as my own I have hereunto aflixed my signature in presence of two witnesses.
