UNITED STATES PATENT OFFICE.

JAMES M. MCCOOL, OF MONTGOMERY, ALABAMA.

REFRIGERATOR;

SPECIFICATION formin part of Letters Patent No. 724,319, dated March 31, 1903.

Application. filed July 29, 1902. Serial 110.117.488; (No model.)

To all whom it may concern.-

Be it'known that I, JAMES M. MCCOOL, a citizen of the United States, residing at Montgomery, in the county of Montgomery and State of Alabama, have invented new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to refrigerators of that class embodying a series of independent storage-receptacles adapted to separately contain as many different commodities orarticles.

The purpose, mainly, of the present improved form of refrigerator is to utilize cold currents of air in the most advantageous manner and establish a circulation thereof around and between a series of independent receptacles or storage-compartments, which are accessible without permitting the exterior warm air to flow into the cooling-chamber of the refrigerator and moderate the temperature of the latter, and thereby economize in the use of ice in maintaining the desired low degree of temperature.

A further purpose of the invention is to so construct a refrigerator that the cold-air currents will separate from and be uncontaminated by the water of condensation or drip descending through the cooling-chamber from the ice-box, and thereby establish a dry cold, with material advantage in refrigeration.

A further aim of the invention is to provide a refrigerator having a chamber in which are disposed a series of independent receptacles which are accessible from the exterior without permittingthe entrance of the surrou nding air to the said chamber, and also a cold-storage chamber at one end, which can be used without in the least aflecting the independent reoeptacles, the said cold-storage chamber being arranged near the ice or other refrigerant inclosure.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a perspective View of a refrigerator embodying thefeatures of the invention. Fig. 2 is a longitudinal vertical section of the same, taken through the center thereof. Fig. 3 is a transverse vertical section on the line 3 3, Fig. 2. Fig. 4 is a horizontal section on the line 4 4, Fig. 2.

Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates an elongated rectangular inclosure or casing, which provides a refrigerating-chamber 2, and rising from the front end thereof is a vertical auxiliary inclosure or casing 3, having an inlet-door 4 and surrounding a cold-storage chamber 5. The bottom, sides, and end of the inclosure or casing 1, as Well as the similar parts of the inclosure or casing 3, and also the top of the latter, are formed with double walls which are spaced apart and have a suitable heatnon-conducting material, as clearly shown by Figs. 2, 3, and 4. The door 4 will also be suitably packed in the most approved manner, and all of the well-known incidental structural features of refrigerators as now commonly manufactured and tending to produce a superior refrigerating inclosure will be applied to the present improved device. Within the upper portion of the storagechamber 5 is an ice-chamber 6, having an open bottom with an ice-rack 7 disposed thereon and also provided with a door 8, which will be suitably packed to prevent the ice from being attacked or afiected by the exteriorair when the door 7 is open. The top wall 9 of the ice-chamber is independent of the top wall of the inclosure or casing 3 for economic preservation of the ice in the chamber 6, and closely joined to the lower open end of the ice-chamber is a metallic chute 10, formed with a lower elbow 11 and an outletmouth 12, extending into the chamber 2 at the front'of the latter.

Within the chamber 2 are a series of independent receptacles 13, which are fully closed except at their upper ends and have blocks 14 interposed between the bottoms thereof and the bottom of the chamber'2, the said blocks'being located at the corners of the bottoms of the receptacles. By elevating or raising the bottoms of the receptacles 13 airpassages are provided thereunder; Over the 1 top of the chamber 2 is a frame 15, compriscles 13 and hold the latter regularly spaced apart to form air-passages.

From the foregoing it will be seen that all the sides and bottoms of the receptacles 13 are fully exposed to the influence of the cold air within the chamber 2. The independent receptacles 13 will be preferably porcelainlined, and over their upper open tops transverse slides 19 are mounted to engage the grooves 17 and have central upstanding grips 20 for operating the same and drawing them outwardly from either side of the casing or inclosure 1 to disclose andrender accessible either one of the receptacles 13 with which each codperates. The slides 19 have transparent panels 21 therein, through which the commodities or articles contained within the several receptacles may be inspected without opening the said slides.

The chamber 2 is separated from the lower portion of the chamber 5 by a front vertical partition 22, and therethrough the mouth 12 of the chute extends and is disposed over the front end of a central trough 23, extending longitudinally through the chamber 2 and has a downwardly-directed curved outlet 24, projecting through the lower portion of the rear end of the inclosure or casing 1, as clearly shown by Fig. 2. This trough 23 is disposed close to the bottom of the chamber 2 and is gradually inclined downwardly from its front end to the outlet 24. The water of condensation or drippings from the ice in the ice-chamber fall downwardly through the chute 10 and strike the elbow 11 and by the latter are directed into the trough 23 and pass out through the outlet 24.

The cold air passes from the ice-chamber 6 downwardly through the chute 10 into the chamber 2 and circulates around the recep: tacles 13, and there being no outlet or escape for the currents of air within the chamber 2, except through the door 8 when the latter is opened at long intervals to replenish the chamber 6 with ice, will result in maintaining a uniform and low degree of temperature in the said chamber 2.

The cold-storage chamber 5 can also be employed with advantage for preserving meats or other large articles which are rendered readily accessible through the medium of the door 4 Without interfering with the temperature of the chamber 2.

The improved refrigerator will be found exceptionally useful in stores, hotels, and other places where large quantities of different commodities are required to be refrigerated, and the proportions of the refrigerator may be varied to accommodate different uses or to increase the capacity thereof. It will be also understood that the proportions and dimensions of the improved refrigerator maybe varied to adapt it for domestic use, and in the construction of the device changes in the form and increase in the number of receptacles and a variation in the minor details may be made without departing from the principle of the invention.

Having thus fully described the invention, what is claimed as new is 1. A refrigerator, comprising a front vertically-disposed cold-storage chamber, an icechamber located in the upper rear portion of said storage-chamber, the said ice-chamber being a closure distinct from the storagechamber and having an independent door and also provided with a depending chute with a lower curvedend, a distinct refrigeratingchamber extending from the lower rear side of the storage-chamber and separated from the latter by a partition through which the lower curved end of the chute extends, the bottom of the ice-chamber opening fully into the upper end of the chute, and a series of independent receptacles mounted in the refrigerating-chamber and having fully-closed bottoms and sides and accessible from the top, the said receptacles being separated from each other and the adjacent sides and ends of the refrigerating-chamber and also having their bottoms elevated above the bottom of the latter.

2. A refrigerator, comprising a front vertically-disposed cold-storage chamber, an ice chamber in the upper rear portion of said storage-chamber in the form of a distinct in closure having adoor and also provided with a depending chute with a lower rearwardlyprojected end, a refrigerating-chamber connected to the lower rear portion of the storage-chamber and completely separated from the latter by a partition, the lower end of the chute extending through the said partition above the bottom of the refrigerating-chamber, a series of independent receptacles mounted in the refrigerating-chamber and having fully-closed bottoms and sides and accessible from the top, the said receptacles being separated from each other and the adjacent sides and ends of the refrigeratingchamber and also having their bottoms elevated above the bottom of the latter, and a downwardly and rearwardly inclined trough extending from the partition under the lower end of the chute to and through the rear end of the refrigerating-chamber;

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