ALAN K. GILLESPIE, OF ST. LOUIS, MISSOURI, ASSIGNOB. TO BRECHT COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI.

REFRIGERATOR.

To all whom it may concern!- I Be it known that I, ALAN K. Grnnssrm, a citizen of the United States of America, residing at the city of St. Louis, State of Missouri, United States of America have invented a corta in new and useful ltefrigerator, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, forming part of this specification.

My invention relates to an improvement in counter refrigerators, and its objects are to provide an arrangement in which the refrigerating means is situated below a display chamber in connection wi 111 ns for maintaining a suitably low in rature throughout the display chamber; to provide an eflicient and novel form of ice chamber; and to so arrange all the parts as to form a refrigerator having storage and display chambers in which the display chamber will be of convenient height. and easy of access. Other objects and advantages of my invention 'will appear from the following more detailed description. I

In the accompanying drawings, Figure l is a front elevational view of a refrigerator constructed in accordance with my invention; Fig. 2 is a view partly in plan and part1 in horizontal section along line 2-2 of Fig. 1; Fig. 3 is a vertical transverse cross section along line 3-3 of Fig. 1'; and Fig. t is a perspective view of the ice chamber.

The refrigerator is provided with the usual suitably insulated walls, and comprises a display chamber 1, a storage chamber 2 and ice chambers 3, spaced apart and situated between the display chamber and the storage chamber. The ice chambers communicate with a common ice hopper xi, closed by a plurality of doors 5. This hopper is provided with an inclined interior surface 6, as shown in Fig. 3, which facilitates the forcing of ice from the hopper into the ice chambers 3.

The display chamber is provided with doors 7, partly of glass, and the front wall of this chamber is formed of a plurality of spaced glass plates 8. 6* I The ice chambers 3 terminate shprt 9f the front wall of the refrigerator, and an insulating member 9 passing lengthwise of Specification of Letters Patent.

,frigcrator cooperating "also results in an even the refrigerator and across the ends of the ice chambers forms, with the front wall of the refrigerator, an air passage 10, connecting the storage chamber 2 with the display chamber 1. A glass ballle plate 11 extends I Patented Jan. 8,1918.' Application filed October 26, 1916. Serial No. 127,764.

lengthwise of the display chamber and from the insulating member 9 to a point near the top of the chamber and forms, with the front wall 8, a continuation of the air pas sage 10.

A drain pipe or pipes 12 are provided for the ice chambers and are placed in any suit able position. Articles to be kept cool are placed in the storage chamber 2 through a door 13, or if they are to be displayed, into the chamber 1 through a door 7.

the operation of the refrigerator the an is brought to its lowest temperature while between and adjacent to the ice chamzers The warmest air will of course be at djacent to the walls of the chambers, and particularly in the passage 10. The condition just dcscri ed leads to the circulation of air from the displaychamber downward between the various ice chambers and upward to the display chamber through the passage 10. This circulation will be continuously maintained, because the temperature of the air is always reduced, while passing between the ice chambers 3, to a point below that of the air in other parts of the chamber, and this heavier air moves downwardly,displacing and forcing through the passage 10 the lighter air underneath it.

It will be noted that with the form of ice chambers I employ, a very large area of with the result that I may use a smaller quantity of salt in the ice chambers, or I can reducethe temperature in the refrigerator to a point lower than would be ossible if a smaller area of cooling sur ace were provided. The spacing of the ice chambers throughout the length of the re with the baffle 11, distribution of cooled {lair throughout all parts of the display cham- Having fully described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A refrigerator comprising an upper display chamber, a plurality of containers for cooling means located beneath said chamber and spaced apart to provide a plullt) rality of fines for the egress ofair from the display chamber.

2. A refrigerator comprising an upper display chamber, a lower chamber, a plurality of containers for cooling means located beneath said upper chamber and spaced apart to provide a plurality of flues for the downward passage of air from the upper to the lower chamber, and a flue for the upward passage of air from the lower to the upper chamber.

3. A refrigerator comprising a lower stora e chamber, an upper display chamber, a plurality of inclosed ice containers between said chambers and spaced apart to provide a plurality of passages between them from the upper to the lower chamber, and means forming a passage for the return of air from the lower to the u per chamber, said means comprising a mail extending to the upper part of the display chamber.

4. A refrigerator comprising an upper display chamber having a transparent front wall, a lower storage chamber, co tainers for cooling means located betwee said chambers and spaced apart to providd pas tainers, said air passages communicating with therefrigerating chamber and spaced over one wall of said chamber.

6. In a counter refrigerator, the combination of an upper display chamber, a lower storage chamber, a plurality of inclosed ice containers located between said chambers and spaced apart, said containers extending to a point back of the display chamber, and

.an ice hopper communicating with the rear portions of said chambers.

In testimony whereof, I have hereunto set my hand andafiixed my seal.
