REFRIGERATOR.
Specification of Letters Patent No. 20,907, dated July 13, 1858.
To all whom t may concern:
Be it known that I, NATHANIEL I/VATER- arxiv, of Boston, in the county of Suffolk and AState of Massachusetts, have invented an Improved Vent-ilating-Befrigerator for Cooling Meats, Vegetables, &c.; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which- Figure 1, is a top View; Fig. 2, a front elevation; Fig. 3, a longitudinal section, and Fig. 4, a transverse section of it. Fig. 5, is a top View of the grooves and orifice of discharge of the auxiliary bottom, as will be hereinafter described.
In such drawings, A, denotes a box, or case made with a cover or lid B, so applied to it as to be capable of being turned upward in manner to uncover the chamber or refrigerating space, C, within such case. In constructing the said case, I make it of any proper material or materials and in any suitable manner to render it a non-conductor of heat. I also make it with ledges, shelves or like devices suchv as may be useful in supporting ice and meat, vegetables or other matters within it. Generally speaking, the ice or cooling medium should be placed in the upper part of the refrigerating chamber, C, wherein it may be sustained by means of a tray, b, arranged as shown in Figs. 3, and 4.
Through the case, A, and into the upper part of the refrigerating chamber I lead one or more air pipes, D, and cause such to descend within the refrigerating chamber and open at nearly the bottom thereof. And on the opposite part of t-he case or in any other proper portion thereof, I arrange one or more other pipes, E,which I lead from the lower part of the refrigerating chamber through its case, and upward outside of the same nearly to the lid or cover. Each pipe is to be open at both of its ends. Furthermore, in the lid or cover B of the case or through the upper part of the case I lead a pipe, Gr, and surround the said pipe by a space or chamber H, closed at its bottom and open at its top, such chamber and pipe being disposed within the case, as shown in Figs. l, 3, and 4.
In the drawings, the case is shown as furnished with a metallic lining I, which covers and protects the entire inner surface of the refrigerating chamber and has a discharge pipe K, leading out of the chamber and through the case and from the middle of the bottom plate, c, of such lining.
Beneath the lining is an auxiliary space or the wooden bottom, L, of the case formed with channels or-grooves M, M, in its upper surface and radiating from or made to communicate with a common opening, passage or pipe, N, which in Figs. 3 and 4, is shown as extending around the discharge pipe, K, of the metallic lining. The said pipe, K, leads out of a cesspool, O, covered by a cap or valve, P, the same being constructed in such manner as to drain the refrigerating chamber of water without admitting air into it; such a mode of making a cesspool and valve or cover is well known and in common use.
In the operation of a refrigerator so made, the air by passing down through the inlet pipe or pipes, D, D, become cooled by contact with the part or parts thereof which may be situated within the refrigerating chamber. After circulating within the refrigerating chamber and becoming further cooled or foul such air passes into and escapes through the eduction pipe or pipes and as these pipes are principally situated on the outside of the case they will be vexposed to the external atmosphere so as to be warmed thereby in a manner to produce an ascending current of air through each of them. Thus it will be seen that by the arrangement of the air supply pipe or pipes; viz, within the refrigerating chamber in connection with the arrangement of the air discharge pipe or pipes, viz, without the case as described, the ventilation of the said chamberl will be carried on to great advantage, and with economy so far as melting of the ice is concerned. Furthermore, by arranging about the odor discharging pipe Gr, and within the lid of the case as described an encircling chamber, I-I, closed at bottom and open at top, the outer surface of the said pipe G, will be in contact with the external atmosphere, and by being warmed thereby the air in the pipe will be rarefied so as to ascend and create a current favorable to the discharge of eflluvia or bad odors.
By means of the grooved auxiliary bottom arranged under the metallic lining of the refrigerating chamber any leakage.
the absorption of Water into the Walls or sides of the case Will be prevented to a great extent if not entirely. It frequently happens that holes in the bottom of the inner lining are made by ice pricks or other instruments. Through such holes the Water of the refrigerating chamber' will find its Way into the main bottom and stuiling of the case, and more or less injure the same as a non-conductor of heat. By the grooves in the auxiliary bottom, such leakage will be caught and directed toward the discharge pipe.
I claim-- l. The above described arrangement of the air supply and discharge pipes With respect to the case and its refrigerating chamber, in which arrangement the supply pipe or pipes are disposed partly Within the refrigerating chamber, While the discharge pipe, Gr, the same being to operate in mannerV and for the purpose, set forth.
In testimony whereof I have hereunto set my signature.
