FRED E. RANNEY, OF GREENVILLE, MICHIGAN.

REFRIGERATOR.

:PEGIEICATI-DN forming part of Letters Patent No. 548,818, dated October 29, 1895.

Application ned March 25,1895.

.To all whom it may concern,.-

' Be it known that I, FRED E. RANNEY, of' Greenville, in the county of Montcalm and State of Michigan, have invented certain new and useful Improvements in Refrigerators;

and I do hereby declare that the following is a4 full, clear, and exact description thereof, ref-l erence being had to the accompanying drawings, and to the lettersof reference marked thereon, which form a part of this specifica? tion.

This invention relates to improvements in d ry-air refrigerators, or refrigerators in which the interior construction and arrangement are such as to secure a definite and continuous circulation of air from the ice to the provision chamber and back again to the ice-chamber without any condensation of moisture within or upon the walls of said provision-chamber, so that the atmosphere of the latter is at the same time maintained cold and dry.

The object of the present invention therefore is to provide a dry-air refrigerator of the character under consideration in the constructionof which the ice-compartment shall be constructed of non-conducting material,

shall also be suitably lined with metal, and may be removable as a whole from theref ri gerator to facilitate cleansing of the refrigerator andthe easy repairs thereto and to the ice-compartment, and whereby the refrigerator may be more easily filled with ice without interfering with, but, on the contrary, increasing,

the proper circulation of dry air, and where front andback wallsof the refrigerator, A2 A2 its Side walls, and A3 and A4 the bottom and top thereof. Said walls and bottom are rigidly secured together in the usual manner to form a rectangular box or chest and are each Asuitable non-conducting material.

Serial No. 543,036. (No model.)

preferably made of two separate thicknesses of wood, with an intervening filling a. of any The top A4 is hinged to the rear end wall A of the chest in the usual manner, and a door A5 in the front wall A affords access to the provision-chamber A6,' which comprises the lower portion of the chest. v

B designates a removable ice box or chatnber, which normally occupies the entire upper portion of the refrigerator and is adapted to be inserted and removed through the open upper en d thereof when the top hinged cover A4 is thrown back. Said ice-box B is comprised of front and rear walls B and B2, end wallsBSB'and a bottom B4. The depth of the box'B from front to rear is made such that its walls B and B2 tit closely against the front and rear walls A and A of the refrig t erator and serve as so much additional insulation to resist the influence of the outside air. The width of the box between the ex.- ternal faces of its side walls B3 B2 is made shorter than the internal width of the chest, so as to leave spaces C C between said walls B3 B2 and the side walls A2 A2 of the chest, which spaces constitute the lateral warm-air lines of the refrigerator.

Vertical cleats B5, secured to the lateral faces of the box B, at the front and rear edges thereof, serve to accurately locatethe box centrally between the side Walls A2 A2, the outer faces of said cleats fitting against the inner faces of said Walls A2 A2 when the box is placed in position. The upper edges of the side walls B3 Bs terminate sorne distance below the top of the box and aiford apertures c, through which the warm .air is discharged from the iiues C into the ice-compartment.

` strengthen the box and as handles by which it may be conveniently lifted.

The bottom B4 of the box is provided at its center with an elongated aperture C', extending the greater part of the distance from the front to the rear wall thereof and forming the downdraft or cold-air flue ofthe refrigerator.

ICO

Said bottom B4 is also provided at some suitable point with a drip-opening b, which in this instance is located directly behind the aperture C', close to the rear wall B2 of the box. A drip-pipe D, secured in the lower portion of the refrigerator, immediately below the drip-opening b, and extending down through the bottom A3 of the chest, serves to conduct off the drip in the usual manner. p

The ice-chamber B is supported within the refrigerator upon horizontal ledges a. a2, provided on the front and rear walls A and A. The front ledge ca is herein shown as formed by the upper surface of a cleat E, which is secured to said front Wall A just above the door A5, while the rear ledge 0. is formed partially by a somewhat narrower cleat E on the rear wall and partially by rabbeting the upper portion of the said wall to form a shoulder at this point.

F indicates an ice-rack of any approved form.

As herein shown, the refrigerator is lined throughout in the usual manner with zinc or other suitable sheet metal. The lining A7 of thebody of the chest covers the inner walls of the lower portion thereof and extends at the sides up through the flues C. The lining B7 of the ice-box covers the interiorthereof and is applied to the cleats B6 as well. Around the central Hue C said lining is turned up to form a surrounding ledge b', which prevents any drip from passing into said flue, and the whole of the lining is inclined slightly toward the drip-opening b to secure the proper drainage of the box. The latter is also provided with a depending nipple b2, which projects into the funnel-shaped top d of the drip-pipe D and insures against leakage past the latter.

A lining-plate B8 on the under side of the bottom of the box forms the ceiling of the provision-chamber and completes the lining of the same when the ice-box is in place.

In a refrigerator thus constructed the same perfection of dry-air circulation is obviously attained as in the ordinary dry-air refrigera' tor of the same general type, while at the same time every surface of both the ice and provision chambers and of the several lues can be readily reached for cleaning by simply removing the ice-chamber. When thus removed, the latter can be cleaned byturning a hose upon it, and it can, moreover, be readily carried out of doors or to the ice-house to be filled.

I claim as my inventionl. .A dry air refrigerator provided with an open upper end, a hinged cover, and aremovable ice box fitting within the upper portion of the body of the refrigerator and occupying the full depth thereof from front to rear, the side Walls of the ice box being separated from the side walls of the body by narrow spaces forming lateral warm air flues, and being cut down at their upper edges to afford communication between said flues and the ice chamber, vertical cleats secured to the exterior corners of the box at the front and rear of said iues and litting against the side Walls of the body, inwardly projecting horizontal cleats extending from front to rear of the box above the dues, and forming the handles of the box, and a vertical cold air flue or aperture in the bottom of the box, substantially as described.

2. A dry air refrigerator provided with an open upper end, a hinged cover, and a removable ice box tting within the upper portion of the body of the refrigerator and occupying the full depth thereof from front to rear, said ice box comprising a metal pan and a nonconducting case inclosing said pan, the side walls of the ice box being separatedfrom the side walls of the body of the refrigerator by narrow spaces forming lateral warm airi'lues and being cut down at their upper edges to afford communication between the lines and the ice chamber, vertical cleats secured to the exterior corners of the box at the front and rear of said lues, and fitting against the side walls of the body, inwardly projecting horizontal cleats extending from front to rear of the box above the flues, and forming the handles of the box, and a central cold air fine or aperture in the bottom of the box, substantially as described.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two witnesses.

FRED E. RANNEY.
