UNITED STATES CLAUDY CLARENCE TAYLOR', OF MOUNDS, ILLINOIS.

REFRIGERATING APPARATUS. i l

To ZZ @0l/,0m t may concern:

Be it known that I, CLAUDY C. TAYLOR,

a citizen of the United States, residing at Mounds, in the county of Pulaski, State of Illinois, li'ave invented certain new and useful Improvements in Refrigerating Apparatus, of which the following is a specification.

This invention relates in general to a re frigeratingapparatus, especially adapted for embodiment in a refrigerator display counter.

The object of the invention is to provide a refrigerating apparatus of this character which is capable of efficiently producing and maintaining low temperatures and a Continuous and effective circulation of the dry chilled air through the interior of the refrigerator.

Another object is to provide an apparatus of this character having the foregoing advantages'and capacities and which is at the same timevof simple and durable construction, reliable and economical in operation and easily and comparatively inexpensive to manufacture, install and run.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in theA appended claims, reference being had to the accompanying drawings forming part of this specification, and in which:

Figure V1 is a view in rear elevation showing the preferred embodiment of the invention,

Figure' 2 isa view thereof in central longitudinal vertical section,

Figure 3 is a view in transverse vertical section on the line 3 3 of Figure 1,

Figure 4 is a similar view on the line 4 4 of Figure 1,

Figure 5 is a horizontal section on the line 5-5 of Figure 2,

Figure 6 is 'a detail perspective view of the air deflector employed in connection with each of the upper doors, and

Figure 7 is a view in horizontal section on the line 7-7 of Figure 4.

Referring to the drawings, wherein for the sake of illustration there is shown the preferred embodiment of the invention, the numeral 10 designates the casing of the refrigerator which has its walls constructed in any approved manner so as to effectively Serial No. 664,578.

insulate the interior of the refrigerator and prevent exchange of heat through the walls.

Preferably this casing 1() includes a bottom wall 11, end walls 12, vertical side walls 123 having inwardly inclining or converging upper portions 14 for the greater part of their longitudinal extent and a top wall 15. The side walls 13 at one end of the casing extend vertically for their entire height, as indicated at 14a in order to provide adequate space for the refrigerating unit, to be here inafter more fully described. The front side of the casing is provided with a plurality of transparent panels 16, each of which has embodied therein dead air spaces 17, to prevent exchange of heat. The rear side wall of the casing has embodied in its main portion horizontally swingable doors 18 and has embodied in its upper portion verticallyv swingable doors 19. These doors are mounted on the casing as shown in Figures 1 and 3, for a purpose which will hereinafter more fully be set forth. The interior of the casing 10 is lined with sheet metal, porcelain, or the like, designated at 20, and is designed to provide a provision space 21 having shelves 22 and 23 therein made of trussed cross wires 24 connected by longitudinal member 24n and supported by posts 25 on plates 26 which extend longitudinally along each side of the lower part of the casing as shown in Figures 3, 4 and 5.

y A refrigerating unit, designated generally at 30, is provided in the large end of the casing delined by the entirely vertical portions 14rl of the side walls and comprises a metallic container 31 removably set in the casing through an opening 32 in the top thereof, a door 33 being provided for closing this opening 32. The bottom of the container 31 consists of a plurality of slats 34 secured to a pair of strips 35, and mounted on ledges 36 provided therefor at the bottom of the metallic container. A warm air Hue 37 extends through the upper part of the cooling chamber defined by the container 31 and communicates at one end with a vertically disposed warm air passage 38 defined between the container 31 and the ade jacent end of the casing 10. A plurality of tapered cooling conduits 39 also extend through the cooling chamber below the warm air flue 37 and lead from the warm air passage 38 into the provision space 21. A plurality of tubes 40 traverse each of the cooling conduits 39 and have their ends secured in openings provided therefor in the walls of the conduits and freely communicating with the interior of the cooling chamber. 1t is obvious that the cooling conduits 39 and theiiI tubes 40 embody broadly the invention shown7 described and claimed in my cti-pending application filed Feb. 28, 1923, Serial No. 621,804. These cooling conduits are, however7 adapted for organization with the parts of the present invention in that they gradually enlarge from the point at which they con'imunic-ate with the warm air passage 36 to the point at which they discharge into the provision space and in that they incline downwardly from the warm air passage to the provision space. They are also provided with defleeting lips 4t2 which project into the warm air passage 38 and which insure deflection of certain of the air in said passage through the cooling conduits.

A series of ballles l5 are provided and extend transversely between and are carried by the inclined upper portions 15 of the side walls just below the top thereof` and define a return passage 46 for conducting the warm air, which arises from the provision space or enters the interior of the refrigerator when the upper doors are opened, to the flue 37 of the cooling chamber. These baffles are o't' progressively increasing inclination as they proceed from the flue 37 and certain of the baffles remote from the flue 37 are provided with depending flanges l17. A drip pan 50 is arranged below the slatted bottom of the cooling chamber for collecting the refrigerant discharging therefrom. This drip pan 50 is spaced from the bottom wall of the casing and from the adjacent end wall thereof to provide a passage 51 constituting a continuation ol the warm air passage and a passage 52 communieating with the passage 5l. and extending below the drip pan 50. At the opposite end ol the casing from the drip pan 50 an outlet pan 53 is provided and communicates with the drip pan 5() by means of a plurality of large pipes which extend along and are slightly spaced from the bottoni wall 11 of the. casing. The drip pan 50 and the outlet pan well as the pipes 53 are suitably supported on the plates 26. A discharge pipe 56 is provided for carrying ofl the water from the outlet pan to any suitable point of discharge exteriorly of the refrigerator, and within the outlet pan this discharge pipe 56 has a trap 57 embodied therein. A series of baffles 58 are provided on the pipes and are supported on the plates 26 or on the pipes themselves as desired. If found necessary these baffles may also assist in support of the pipe in which event they are (arried by the plates 26. A small air pipe 60 is provided for each pipe and extends from the passage 51 through the drip pan 50, the pipe 55 and the outlet pan and discharges at a point 61 communicating with the provision space. The ends of the pipes which communicate with the space or passage 51 are provided with defleeting lips 63 arranged to insure the passageA of air through the pipes 60.

A. deflector 65 is provided for each door 19, the deflectors being carried by the inclined portions 15 of the rear walls of the casing and having inlet openings 66 conimunicating with the door opening andl outlet openings 6T communicating with the passage 46, the baffles 4T being suitably cut away to accommodate each deflector 65.

In practice the cooling chamber 31 is filled with crushed ice which may be sprinkled with salt and this ice not only encloses the cooling conduits 39 but also is disposed in the tubes 40 to exert a cooling and chilling effect on the air in the conduits through the conduits 39 and the walls of the tubes 40. As the airin the conduits 39 is chilled it rolls down through the conduits into the provision space 21 following the course of the arrows applied to Figure 2. In the provision space it abstracts heat from the provisions and rises up through the spaces between the baflles 45 into the passages 46 through which it flows to the warm air llue 37. From the warm air flue 37 it passes dtnvnwardly through the warm air passage 3S from whence it again passes through the conduits 39. However, some of the air in the passage 38 will drop down past the lips 42 of the conduits and into the passage 51, it being borne in mind that the air in the passage 38 is being cooled in its downward course through the cooling effect of the ice in the cooling chamber' exerted through the wall of the metallic container 31. At this time the ice in producing its cooling effect has melted and the salt sprinkled on the ice has also melted and commingled therewith and the resultant brine drops down through th e slats 34; into the drip pan 50 from whence it flows through the large pipes 55 to the outlet pan 53. llVhile in the pan 50 and while passing through the. pipes 55 the brine exerts a cooling' effect on the air that has dropped down into the passage 51 and flows from the passage 51 through the passage 52 along and between and beneaththe pipes All along the pipes 55 portions of this air is being deflected upwardly into the provision space 51 by the bailles 58. The doors 16 are so arranged with respect to the direetion of vflow of the air that when they are open the inrushing air will flow into the interior of the casing in the direction of flow and thus accelerate circulation within the refrigerator. The same is true of the doors 19. It is to be noted that these doors 19 coact with the deflectors 65 when the doors are closed to force circulation for as the doors 19 are closed they fan the air through the cleflectors into the passage 46 causing the air to flow through the passage 116 to the warm air flue 37 and thereby enhancing` the circulation.

lVhile I have herein shown and described the preferred form of my invention it is to be understood that I do not limit myself to the precise construction herein set forth as various changes in the form, proportion and the minor details of construction may be made without departing from the spirit of the invention and the spirit and scope of the appended claims.
