CHARLES N. SHAV, OF PETOSKEY, MICHIGANJ MEAT-FREEZER.
SPECIFICATION forming part of Letters Patent No. 316,840, dated April 28, 1885. Application mea Npvemter a6, 1834. (No model.)
To all whom, t may concern.-
Beit known that I, CHARLEs N. SHAW, a citizen of the United States of America, residing at Petoskey, in the county of Emmett and State of Michigan, have invented certain new and useful Improvements in Meat Freezers, vof which the following is a specicatiomreference being had therein to the accompanying drawings.
This invention pertains to improvements in refrigerators, having for its object not only to keep meat, oysters, poultry, &c., in a frozen condition and state of preservation, but also to prevent ingress of air in the ice-chamber, and to expedite the storing and removal of the articles to be preserved 5 and it consists in the combination and arrangement ofthe parts, substantially as hereinafter fully set forth and claimed.
In the accompanying drawings, Figure lis a sectional elevation of the refrigerator. Fig. 2 is a view in perspective embodying my invention. Fig. 3 is a detail view thereof, and Fig. 4 is a view in perspective of my invention in its closed condition.
In carrying out my invention I employa refrigerator, A, preferably cylindric, comprising an outer wall, A', and an inner Wall, A, forming a chamber, B, for reception of charcoal or other well-known non-conducting material. The two walls A and A2 are connected at the top by an air-tight cover, a'. The4 bottom a of the refrigerator is also constructed with two horizontal Walls, forming a chamber, B, wherein is inserted non conducting packing material.
To the inside of the bottom a of the refrigerator is rigidly secured or cast integral therewith a circular vertical strip, b, which is designed to prevent jarring or displacement of the inner cylindricreceptacle or can, C.
The receptacle or can C is designed for reception of the article or articles to be frozen or kept in a state of preservation. The rim of the can or receptacle() has secured thereto rubber packing b, and in connection with cover F renders can C air-tight.
The ice-chamber D is formed between the inner wall,A`l, of the refrigerator A and the can or receptacle C.
Removablyhinged or secured to air-tight cover a is a circular lid or cover, E,Which covers the ice-chamber D air-tight, the inner edge of the cover a being provided with rubber packing e on the horizontal face of a shoulder, e', on which the corresponding shoulder of the cover E fits, and is tightly and securely held in position by means of a pivoted thumbpiece, en.
Disposed centrally in the cover E, and of the same width asthe can or receptacle C, is another circular lid or cover, F, hinged to the cover E, and is rendered air-tight in like manner, rubber packing f being secured on the outer edge of the shouldered opening therein. The lid or cover F may be tightly secured by the pivoted thumb-piece f or other ordinary means.
The coldest temperature that can thus be obtained from ice alone is about thirty-four (34) degrees above zero; but by adding salt to the ice atemperature as low as four (4) degrees above zero may be produced. Consequently, by placing ice in the ice-chamber D and adding sufficient salt a low temperature may be obtained, and the refrigerator being air-tight this temperature may be retained. The salt on the ice soon runs off with the drip from the ice through a drip-pipe, G, in the bottom a', leaving the temperature in the icechamber D about the same as before the salt was applied to the ice. The temperature in the can or receptacle C being much colder than that of the ice-chamber D, the temperature is equalized with that of the receptacle C, thus causing the ice to remain solidly frozen and economizing its consumption. The temperature in the receptacle C is thus rendered sufficiently cold to keep fresh meats, sh, oysters, rc., in a frozen condition for several days.
From the foregoing it will be seen that access can be had to the receptacle C through the lid or cover F without exposing the ice in chamber D, which also greatly economizes the ice.
My invention also embodies an elevator, K, which comprises a convenient means of storing therein such articles as fresh meats, fish. poultry, and game, and is especially adapted for t-he use of hotels, families, meat-markets, &c.
To the air-tight cover ct, l secure by brack- IOO ets two standards,.G, of corresponding size.
Thesestandards G are connected at'their up' per ends'by a vcross-bar, g,to whichis securedon its upper surface, directly over the center of cover F, a pulley, H, and on the outer righthand corner is secured a pulley, H', the purpose of which will appear Vfurther-on.
To the inner under side of the cover F, I secure three vertical rods, h h and h', the rods h h being directly opposite each other andcconnected together at their upper edges by a bar, Y
h2. To these rods I attach two or more hoops or bands, o, having each secured thereto aseries of hooks, o', for hanging thereon `to be Ipreserved fresh meat, Ste. The hoops or bands extend only a short distance beyond the two opposite rods h-h, to allow of more convenient laccess to the yinterior of the elevator 'K and Vstoring Vor obtaining of articles to be preserved. Thebar or rod 'L has a tenon formed oueach end,whicl1 is adapted to a corresponding mortise, mprovided in the standards'G, vwhich serves as a guide for the cupboard K.
To the key in the opening in the eyebolt Z is secured an elevating-rope, M, which is'passcd u-p through an opening in the bar g and over pulley H, thence down vover pulley 'I-I, and -to Vthe end of `this rope is connected a counterbalancing-Weight, N, for elevating the cupboard K.
NVhendesired, I dispense with the hoops or bands 0 andtheir hooks, and in lieu thereof 1I attach four or more shelves, I, forming a cupboard, K, as clearly seen in Fig. 3.
'It will be seen that my invention is both `durable andeconomical, and that it prevents any waste of ice from exposure, that the lid or cover F when opened or removed doesV :not expose the ice, as there is no connection betweenthe receptacle() and chamber D,'and thusconstructed the article or articles in the receptacle C are not'aiffected by the moisture Vof the.iceehamber.
Iam aware that it is not broadly new .to
construct in-connection with a refrigerator an velevator for -receptionzand storing of articles Vto be preserved; but my invention is designed as an improvement on such devices, and is intended mainly to provide in one and the same device means for retaining the ice in a frozen condition Vfora greater period of time than heretofore, and to render the invention particularly adapted for the storage of fresh meats, which alone is an advantage over similar inventions as heretofore constructed, they having been found not applicable for such purpose.
Anotherimportant feature of my invention is the manner in which I construct that part of theV elevator which is inclosed -within'the walls of the refrigerator to permit Vthe ready access V,to the articles stored thereimand to convert the same into a cupboard, thereby vrendering 4the inventionY specially applicable 'for the use of families.
Having thusfully described my invention,
Vwhat I claim, and desire to secure by Letters Patent, is-
l. The elevator K, having bars orrods Vh h and h, hoops or bands o, and .hooks ,-o, arranged'for the purpose'hereiu shown and described.
2. A refrigerator having the removable lid F, elevator K, and lioopsor `bands 0,7.in combination with the cover E andairftightcover
