J. SCHULDE REFRIGERATH Filed Jan. 2, 1923 Patented July Z2, lli.
UNITED STATES Parana Application filed .''anuary 2, 1923.
To nl!" tf1/mm 'it may concer/t.'
l'le it known that l., JOHN ScrrULnr., a citiaen of the United States, residi g at gt Louis, State of Missouri, have invented certain new and useful Improvements in itefrigerators, of which the following` is a spec-- ification.
illy invention has relation to improvements. in refrigerators of the display c se type, and consists in the novel features of construction more fully set forth in the specification and pointed out in the claim. The invention relates more particularly to refrigerators wherein a mixture of ice and salt is availed of for obtaining the required temperature, said mixture being contained in a tank at one end of the display case, means being provided for the circulation of the resulting brine in the case.
The principal object is to provide a tank that is mounted on an axle within the case so that it may be tilted through the open door to facilitate loading. Another object is to provide vents near the top of the display section of the case to permit the warmer air to escape therefrom thus avoiding the accumulation of water of condensation on the glass panels.
Further objects will be better apparent from a detailed description of the invention in connection with the accompanying drawings, in which- Figure 1 is a front view of the display case with the front wall broken away at one end to disclose one of the refrigerator compartments; Fig. 2y is a composite vertical transverse section taken through the case on the line of Fig. 1, and through the brine troughs on the line' QH--Qt of said figure. the lower part of the ice tank being in elevation 5 Fig. 3 'is a vertical longitudinal section of a refrigerator compartn'ient taken on the line 3 3 of Fig. 2; Fig. is a horizontal longitudinal section taken on the line 4 4 of Fig. 1.
Referring to the drawings, 1 represents a refrigerator display case haif'ing refrigerator compartments 2, 2 at the ends and a displa7 compartment 3 therebetween, the latter compartment having a front wall composed of three glass panels 4;, 4f, 4t, separated by mullions 5, A vent e ln branches 6', 6 passes through each inullion the top sothat the warmer air rising within the compartment 3 may escape to the Serial No. 610,?
outside, thus prei enting the panels at from sweating.
A curved horn 12 of uniform width and tapered toward the top is n'iounted within the tank, the large end of said horn passing through the inner side wall of the tank below the center thereof, and the small end (open at the top) being spaced a short distance from the cuter side wall and secured thereto a channel 1S a short distance below the open top of the tank. rilhe front and rear walls of tl e tank T taper slightly toward the bottom, and the bottom slopes downwardly toward the center thereof where it is provided with an inwardly extending recess 141. The tank is provided with two discharge spouts 15, 15 for the salt brine, a spout on each side of the recess 14, said brine discharging from the speuts into the troughs 16, it resting on the bottom of the case.Y in a double case (as shown in Fig. 1) there is a pairof troughs integrally formed, leading from each refrigerator compartment 2, the two pairs coming togeti'ier at the center of compartment 3 and having a common drain pipe 17.
t tube 1&3 passes through each trough 16, said tube being spaced from the sides of the trough and mounted in the end walls thereof.
llU
The tubes are open at the ends and pass through the end Walls of the trough thus forming a flue passage-Way for air, throi'lgh the brine in the trough. The brine is maintained at a constant level in the trough by the overflow discharge pipe 19 leading into the drain pipe 17.
The operation of my improved refrigerator is as follows:
Assuming the tank 7 to be filled With a freezing mixture, the compartment 2 will be cold. However, following natural laws, the air in the upper part of said compartment entering from the adjacent compartment 3 will not be as cold as the air in the lower part of compartment 2. After the air enters compartment 2 its temperature is reduced and it falls, some entering the horn 12, Where it is further reduced in temperature by the surrounding refrigerant. Thus the air will move steadily downward through the horn 12 which cnlarges toward the discharge opening to permit a free and unimpeded discharge of cold air into compartment 3. Cold air will also be forced through the recess 14 and under the bottom of tank 7 into compartment 3 by the super-incumbent air that is being cooled by contact with the outer Walls of tank 7 A further cooling eect is brought about in the compartment 3 by the brine-filled troughs 6, 6, and lues 18 through Which the air may pass and be cooled.
Having described my invention, I claim: A refrigerator having a cooling compartment and a storage compartment, a refrigerant tank mounted in said cooling` compartment, a horn disposed Within said tank and spaced from the sides thereof, said horn having an inlet near the top of the tank for receiving the Warm air from the top of the storage compartment, and an outlet near the bottom of the tank leading into the storage compartment near the bot-tom thereof, said horn gradually increasing in cross-sectional area from the intake to the outlet thereof. In testimony whereof I hereunto aflix my signature.
