OLIVER M. CAMPBELL, OF VAN BUREN, ARKANSAS.

REFRIGERATOR.

Application filed March 20, 1908.

Specification of Letters Patent.

Patented Sept. *7, 1909.

Serial No. 422,328.

To all whom tt may concern:

Be it known that I, OLIVER M. CAMPBELL, a citizen of theUnited States, and a resident of Van Buren, in the county of Crawford and State of Arkansas, have invented a new and useful Improvement in Refrigerators, of which the following is a specification.

This invention relates to portable or sectional refrigerators, and has for its. object to provide novel details of construction for a refrigerator, that will render it very convenient, insure proper circulation of cold,

dry air throughout the interior of the re-v frigerator, prevent sweaty depositsof moisture on the walls within the refrigerating chamber, and aord perfect drainage for water formed by melting of ice used as a refrigerant.

The invention consists in the novel construction and combination of parts, as is hereinafter fully described and defined in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a vertical sectional view .substantially on the line 1-l in Fig. 2. Fig. 2 is a vertical sectional view of the upper portion of the refrigerator, taken at right angles to the plane of the section-line .1-1, and substantially on the line 2-2 in Fig. l. Fig. 3 is a detached perspective view partly in section showing the drip pan, its supports, and a novel draining device for the water dripping from the ice that is supported by the pan. Fig. 4 is a section on line 4.--4 of Fig. '3, and Fig. 5 is a perspective view of a portion of the inner frame work of the pan, parts being broken away.

The refrigerator body is essentially rectangular and consists of four side walls 5, a top wall 5a and a bottom wall 5b. These walls are each preferably formed with intercellular spaces, illed with any suitable non-conductor of heat, as usual in well constructed devices of this character. It will be noted that the top wall 5a and the bottom wall 5b are both rmly aiiixed upon respective ends of the side walls 5. In one side wall 5 a rectangular opening is formed near the top wall 5a, and in said opening a door 5C is closely fitted and hinged, so as to be adapted for outward swinging movement when access to the interiorofthe body is desired. In another sidewall 5, near the bottom wall 5", a larger rectangular opening is produced, wherein is closely fitted a door 5d, that is also hinged upon the body, so as to be swung outward and give access to the interior of a refrigerating chamber A, that will be further mentioned hereinafter.

Within the refrigerator and below the ice compartment is arranged my improved drippan 6, which consists of a hollow body having at one longitudinal edge a drain trough 6, the upper edge of the outer wall of which is in the saine horizontal plane as the bottom of the pan, so that the air will not be obstructed in itspassage over the pan to the storage compartment of the refrigerator. The pan is preferably constructed as follows: Four timbers a of the same width are joined together at their ends to form a rectangular frame, between the side timbers of which extend the cross pieces a so as to brace and strengthen the same. Upon the upper face of this frame I place paper a2 or otherl non-conductorof heat and over this paper and secured to the frame is the top as, which is preferably formed of tongued and grooved boards. A piece of scantling or other timber a4, having its upper edge beveled or'inclined from one end to the other, is then secured to one of the side timbers a. I then surround the frame thus constructed with fourboards a5, three of which are of a, width to eXtendabove the top a2 to form a ledge, while the other one is of a width that its upper edge is on a level with the bottom of the pan and forms with one of the side timbers a andthe timber a4 a drain ytrough 6a. Upon the lower face of this frame I place paper 'a6 or other non-,conductor and over the paper and secured to the frame is the bottom a7 preferably formed o f tongued and grooved boards. The pan is completed by a facing as of galvanized iron or other rust-proof sheet metal for the top of the frame and the trough, the facing being secured to the upper edges of the boards a5. The area of this drip-pan body` is so relatively proportioned, that when in position a suitable space will be afforded between the sides thereof and the corresponding side walls 5 of the refrigerator body.

Preferably for large refrigerators the drip-pan 6 is hung from the top wall 5a by a plurality of suspension-rods 7, which at ffl their lower ends are secured upon the side walls of the pan. The upper ends of the rods 7 pass through the top wall 5a, and reinforcel strips 5@ thereon, that adapt the rods for receiving washers and nuts 0, thus l'langing the pan from the top wall, as shown in liigs. l and 2, centrally in the body of the refrigerator. The pan, as shown in the drawings, is supported by bracket strips t, which in turn are supported at the ends by uprights it extending to the floor. Preferably the pan 6 is disposed somewhatabove the lower door 5d and is given a slight inclination from a horizontal plane.

Upon the upper side of the drip-pan G a number' of batten strips z' are seated at suitable distances apart, each strip being divided into sections, three in number in this case, and each sectional batten-strip is tapered longitudinally a degree that will render the upper sides of these sectional strips horizontal when all are seated upon the upper surface of the drip-pan. Upon corresponding sections of the batten-strip c' a plurality of slats m are affixed, which are spaced apart parallel with each other, and when in position produce a slatted tray that covers the drip-pan, said tray receiving the ice that is placed in the upper portion B of the refrigerator body, through the doorway having the door 5C as a closure. The slatted tray is level on the upper side, so that ice will remain without slipping where it is placed, thus permitting the even storage of ice in the ice-chamber, while the waste water and chilled air will pass down between the slats m over the bottom of the pan to the trough Ga, and thence to the drain pipe g, the water passing into the trough 6a, and the air to the storage compartment. By constructing the slatted tray in sections, convenience is afforded for handling the same when the tray is placed within or removed from the ice-chamber B, which is necessary to enable a thorough cleansing of the refrigerator at proper times.

Upon the side boards c5 of the pan the lower ends of bars a of a slatted rack a is seated, as indicated in Fig. l, said rack being further supported by the suspension-rods 7, whereon it is det-achably held by clip-bands o or other means. Upon two of the other side walls of the ice-chamber B, and also on the door 5C', corrugated guard-walls p and p of wood or metal are secured, and the guard wall 29 thereof, that is opposite to the slatted rack a, rests upon the front board a5 of the pan and is held upright by clips 0, which engage the adjacent pendent suspensionrods 7.

By the provision of the corrugated guardwalls and the slatted rack n, the lining-walls of the ice-chamber B are preserved from injury, and the ice is kept from contact with the walls proper and a circulation of air is permitted between the slats, thus keeping the walls iu a dry condition.

It will be seen that air from the chamber A, below the ice-chamber B, if warmed, will pass up between the inner surface of the side wall of said ice-chamber and the guard-wall 2)', and thence down through the ice in the chamber B, across the same and through the slatted racks a and m, the air thus cooled descending into the lower chamber A and displacing warmer air. The cold air will descend to the bottom of the chamber A and produce a low degree of temperature for the preservation of the food in the storage compartment; and it will be evident that the constant circulation of cold, dry air currents as stated will render the temperature in the lower chamber A uniformly cold and dry.

It will be seen that the novel construction of the improvement facilitates rapid, and proper circulation of the air, and adapts the parts thereof for renewal as long service may require. v
