REFRIGERATOR Application filed February 28, 1908, Serial No. 418,310. Renewed August 20, 1909.

To all whom it may concern:

Be it known that 1, FOREST V. DETWILER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to improvements in refrigerators and it has for one of its objects to provide improved means whereby either the city supply of water, the drip water from a beverage dispensing fountain, or ice may be used as a cooling medium.

A further object is to provide an improved cooling casing including air circulation tubes and in which the circulation of the air from the ice receptacle also acts as a cooling medium to reduce the temperature of the water surrounding the air circulation tubes so that the ten'lperature of the circulating air will not only be materially reduced but will remain substantially the same:

A further object is to provide an improved device of this character whereby the accumulation or the presence of moisture in the cooling chamber will be avoided.

A further object is to provide an improved separable and knock-down cooling receptacle which may be readily removed when desired, and improved means for maintaining said provision receptacle in position.

A further object is to provide an improved device of this character which will be simple and durable in construction and eificient and effective in operation.

To the attainment of these ends and the accomplishment of other new and useful objects, as will appear, the invention consists in the features of novelty in the construction, combination and arrangement of the several parts hereinafter more fully de scribed and claimed and shown in the accompanying drawings illustrating an exemplification of the invention and in which- Figure 1 is a vertical sectional view taken on line 1-1 of Fig. 2 and showing in dotted lines a modified arrangement of the invention.

Fig. 6 is an enlarged detail sectional view of one extremity of the air circulation pipes showing the manner of closing the pipes when it is desired. Fig. 7 is a detail perspective view of the drip pan.

of Fig. 2. Fig. 9 is adetail sectional view on line 9-9 of Fig. 8.

Referring more particularly to the drawings and in the present exem lification of the invention, the numeral 10 designates the outer casing or frame work of the refrigerator, which is packed with the usual asbestos or mineral wool 11. This casing maybe of any desired size and configuration and is preferably provided with an aperture 12 in the top thereof and which is closed by a suitable closure or cover 13.

Arranged within the casing, in the usual manner and resting upon the bottom thereof is a drip pan 14 from which leads a suitable discharge pipe 15. This drip pan l l is of a size to substantially fill the bottom of the casing and is provided with a top 16 which has a suitable aperture located at the center thereof and is provided with an upwardly projecting circumferential flange 17 surrounding the-aperture. The top 16 is preferably inclined from the periphery of the pan toward the flange 17, as shown more clearly in Fig. 8, and is provided with a Fig. 8 is a detail sectional view on line 8-8 series of apertures 18 preferably surrounding theflange 17 by means of which any water of condensation which may accumulate on the top of the pan will be directed into the pan. If desired, suitable supporting legs or brackets 19 may be provided adjacent the corners of the aperture or the flange 17 for strengthening the top and a-lso the flange 17, which latter assists in supporting the removable casing to be hereafter described.

Arranged within the chamber is a cooling casing, which preferably comprises a tank or receptacle 2(), which may be of any suitable depth and of any desired size and is preferably provided with a circumferential flange 21 surrounding the top thereof and which projects beyond the sides and is adapted to engage the inner wall of the casing 10 for holding the tank against lateral displacement.

Depending from and communicating with All the tank or receptacle 20 are a plurality of marginal tubular members 22, which may be of any desired length according to the height of the casing 10, and these depending tubular members are arranged to partially surround the periphery of the tank so as to form a casing having an open side.

A tubular member or pipe 23 is arranged at the bottom of the tubular members 22 so as to connect and communicate with the members 22 and this tubular member or pipe 23 forms a base which is preferably provided with three sides, as shown more clearly in Fig. 2 of the drawings, so that the hollow casing formed by the tank 20, tubular member 22 and tubular member or pipe 23 will be entirely open on one side below the tank or receptacle 20.

The tubular member 23 is preferably of a .width somewhat greater than the diameter of thetubular members 22 so as to form a projecting flange or ledge 24 for a purpose to be hereinafter set forth. Any suitable means may be provided within the casing 10 for supporting the hollow casing thus formed. Suitable and efficient means for accomplishing this purpose comprises brackets 25, which may be secured in any suitable manner to the inner wall of the casing 10 and above the 'd rip'pan 14.

Arranged within each of the tubular members 22 are air circulation pipes 26, which are of a diameter somewhat less than the diameter of the tubular members 22 and these pipes 26 are secured by one extremity to the bottom of thetubular member 23 over suitable apertures therein, and the upper extremities 27 thereof project through the bottom of the tank or receptacle 20 and into the tank and terminate any desirable distance beyond the bottom thereof.

One extremity of suitable elbows 28 may be inserted into the extremities .of the pipes 26, as shown more clearly in- Figs. 1 and 8, so that the free extremities 29 of the elbows will extend toward the inside of the hollow casing.

A separable or knock-down provision receptacle is adapted to 'be inserted through a door opening.30 and into the hollow casing through the open side or end thereof and the door opening 30 is adapted to be closed by a suitable door or closure 31.

The separable provision receptacle preferably comprises a top 32 which may be constructed of any desired or suitable material suchas metal or the like and is of a configuration to' fit Within the casing and of a size somewhat smaller than the interiorof the, casing. The edges of the top 32 are preferably flanged or bent as at 33 to form a downwardly opening groove or recess 34 (shown more'clearly in Fig. 4 of the drawings) and secured to the upper face of the top is a plurality of brackets 35 which are adapted to engage suitable guide ways 36, which latter are preferably secured to thebottom of the tank or receptacle 20, as shown' more clearly in Fig. 3 of the drawings. The'brackets'35 and 36 are so'positioned that the top 32 may be inserted through the door opening 30 in the casing 10 and when the top is 111 position, it will be spaced a short'distance below the bottom of the tank or receptacle.

One edge of the sides and back .37 of the provision receptacle is adapted to be inserted in the groove 34 of the flange 33 on the top 32 and the free end thereof is laterally deflected as at 38 and is provided with an upstruck rib or bead 39 extending the entire length thereof. The bottom 40 of the provision receptacle is provided with sides and back 41 of any desired height and the upper" edges thereof are laterally deflected as at 42 (shown more clearly in Fig. 4 of the drawings) and this laterally deflected portion 42 is also provided with an upstruck portion or bead 43 extending the entire length thereof and is adapted to enter and be seated within the upstruck portion or bead 39 on the laterally deflected portion 38 of the sides and back 37. The laterally deflected portions or flanges 38, 42 of the sides and bottom are so arranged that when the extremity of the sides and back are seated within the groove or recess 34 in the top 32 and the latter is held in position by the

brackets

35, 36, they will rest upon the ledge 24 of the tubular member 23 and the bottom40 will rest upon the upper edge of the flange l7 surrounding the aperture in the top 16 of the drip pan 14.

The sides and back 37 may be provided with a plurality of apertures or openings 44 to permit air circulation through the separable provision receptacle. One series of these apertures or openings 44 are preferably arranged adjacent the free ends of the elbows 28 and another series is preferably arranged adjacent the top 32 of the chamber. If desired, some of the'apertures or openings may be covered by a suitable reticulated material 45, such as wire gauze or the like, to prevent the entrance of foreign matter into the provision receptacle.

Suitable clips 46 may be secured to the outer face of the sides and back 37 of the provision receptacle which are adapted to engage and partially surround the tubular members 22 so as to hold the sides and back of the rovision receptacle against accidental displacement.

Arranged within the tank or receptacle 20 is a suitable ice'receptacle or pan 47 which is preferably provided with a plurality of apertures 48 in the sides thereof to permitthe free circulation of air therethrough and a series of apertures 49 in the bottom to permit the water from the ice to drip into estate the .tank or receptacle 20, and the tank or receptacle is also provided with a series of apertures 50 in the sides thereof adjacent the top to permit :the free circulation of air.

tank 20 and from there it will pass through the tubular members 22 which form the sides of the hollow casing and into the bottom 23 until the bottom and tubular members have been filled with-the liquid after which the water will accumulate in the tank 20. The height of the water in the tank may be" regulated ;by means of a suitable overflow :pipe 52, which latter is preferably arranged within one of the tubular members 22 and extends through the bottom of the tubular member 23 and into the drip pan 14 through a suitable opening in the top thereof and may be held in position by means ofsuitable nuts 53 (shown more clearly in Fig. 1 of the drawings). The upper extremity 'of the overflow pipe 52 terminates short of the up- .per extremities of the tubular members or -pipes26 and by adjusting the upper extremity of the overflow pipe 52'with'respect to the bottom of the tank 20, the height of the water in :the tank may be regulated.

With this improved construction the cold I air in .the tank20 adjacent the ice will pass through the tubular members or pipes 26 to the bottom of the casing 10 .and will be discharged through the elbows 29 and into the cooling chamber through the series of apertures 44 adjacent the extremities 29 of the elbows 28 and will pass upwardly in the chamber to the top thereof and out through the openings or apertures 44 adjacent the top. While the cold air is passing downwardly through the pipes 26- the .cooling medium (water) which is located within the tubular base 23' and the tubular members 22, will maintain the circulating air at a low temperature While the temperature of the air will in turn tend to maintain the water also at a low temperatureand during this circulation of the air the cold temperature which is radiated from the outside surface of the tubular members 22 will pass into the provision receptacle through the apertures or openings 44 in the sides and back thereof to circulate therethrough and upwardly toward the top thereof and pass out of the apertures adjacent the top. The cold air which is discharged through the elbows or pipe extensions 29 will also enter the provision receptacle through the openings 44 adjacent the bottom and circulate through the receptacle. After the air passes out of the cooling chamber, it will tend to rise in the casing 10 toward the top thereof and on the outside of the tank or receptacle 10 until it reaches the apertures 50 in the up per edges of the sides of the tank through which it will pass into the tank and from there will pass through the apertures 48 in the ice pan or receptacle so as to come in contact with the ice 51 therein. This circulation will continue so long as there is suflicient ice to maintain a cold temperature and as the ice melts and the water is drawn off by means of the overflow 52, the air will pass through the series of apertures 48 and always come in contact with the surface of the ice.

\Vhen it is desired to remove the cooling receptacle for the purpose of repair or for cleaning the parts all that is necessary is to open the'door 31 and knock down the provision receptacle by removing the sides and back, orby removing either one of the sides or the back as the case may be. This operation may be accomplished by springing the upstr'uck or beaded

portions

43, 39, out of engagementwith each other and then detaching the other end of the respective member by drawing it out of the groove or recess 34 in the top. The provision receptacle may be assembled by reversing the operation, that .is, by first inserting one end of the side or back into the groove or recess and then springing the beads or offset

portions

39, 43 into engagement with each other.

If desired, a suitable drain cook or valve 54 may be provided at a convenient place,

preferably in the lower face of the tubular in dotted lines in Fig. 7), so that when the valve or cock 54 is opened the contents of the hollow casing may be discharged therethrough and into the drip pan 14.-

Extending into the side of the casing 10 and through one of the walls of the tank 20 is a pipe 57 which terminates in a suitable nozzle 58 and connected to the free end of the pipe 57 is a supply pipe 59, which may be connected to the city water supply and a valve may be provided within the pipe 59. WVhen it is desired to use the city supply of water as a cooling medium, the ice pan or receptacle 47 may be removed (if desired) from the tank 20, although the removal of the ice pan is not necessary. With this form of cooling medium the operation or the circulation is the same as when the ice is used as a cooling medium with the exception that in this instance the cooling medium is running water, which may be supplied to the tank 20 through the pipe 59, the nozzle 58 being reduced as. shown to prevent the pressure of the water from injuring the tank. As the water enters the tank through the pipe 59 it will fill the tubular bottom 23, and tubular side members 22, and accuis located at such a height mulatein the tank 20 to the desired height --tor. If desired, and when the citysupply ofwater is used as a cooling medium, suitable caps or closures 61 (shown more clearly in Fig. 6 and in dotted lines in Fig. 1), may be provided for the tubes 26 to prevent the moisture from passing into. the tubes 26.

The elbows 28 of the pipes 26v are preferably provided with apertures 62 in the lower faces thereof adjacent the drip pan 14 to permit any water of condensation which may accumulate therein to drop upon the to of the pan 14 before the airpasses out the pipe and thereby prevent the moisture from being discharged with the air into the cooling chamber.. I

If desired, and instead of using the city supply of water as a cooling medium and the ice 51, a suitable pipe 63 .may be provided Which is covered with a suitable insulation 64 (shown in dotted lines in Fig.1 of the drawings), which discharges into the tank 'and this pipe may be arranged to receive the drip from a beverage dispensing fountain in which instance the water therefrom will act as the cooling medium.

In a modification shown in Fig. 5 of the drawings the tankor receptacle 20 receives its supply of cooling fluid from a cabinet 65, which is provided with suitable packing or heat insulation 66 and a closure 67 for the opening 68. This cabinet may be supported in any convenient manner and at any convenient point and has communication with the tank 20 by means of the pipe 69 which is preferably arranged on a slight incline as shown, and suitable heat insulation 70 may be provided for the exposed portion of the pipe. The cabinet 65 is provided with a suitable ice rack 71 upon which the ice 72 is adapted to rest and the cabinet with respect to the height of the tank 20 of the refrigerator that the extremities of the pipe 69 will always be submerged, that is, the water level in the cabinet 65 will be the same as the waterlevel in the tank 20 but the cabinet is so arranged as to contain onlysuflicient' water to submerge the end of the pipe 69 while the water in thetank 20 may be of any desired depth. This form of the invention is more particularly adapted for use for dispensing beverages and the cabinet 65 is arranged at a suitable height as to ermit ready access to the ice therein where y the latter ma be shaved when desired for use withthe' everages. I f I With this improved construction of refrigerator the walls of the cooling chamber are spaced from the tubular members 22 thereby preventing the water from coming in direct contact with the Walls of the proand communicating with the base, means whereby said casin may be sup lied with a cooling liquid, and an air circu ation pipe within each of the tubes, said pipes being of a diametersomewhat smaller than the diameter of the tubes and surrounded by the cooling liquid, one end of each of the pipes projecting through the hollow base and. the
