Application mea october 2a, 1924. serial m. 745318.

To all 'whom t may concem.'

Be it known that I, Tmaononn P. Lonmw, of the city of Toronto, in the county of York Province of Ontario Canada a sub]ect of the King of Great i3ritain, have mvented certain new and useful Im rovements in Refrigerator Counters, of which the followin is a specification.

his invention relates to refrigerator counters adapted for use in self-serve stores,

and my object is to devise an attractive refrigerator counter which will display the goods in convenient manner for self-service, and which will keep the goods at a suiiciently low temperature at a reasonable cost for refrigeration.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawingsA 1n which- Fig. 1 is a cross section of therefrigerator counter; and

Fig. 2 a front elevation of the same.

1 is the base from which a counter 2 is supported by means of the legs 3. At the right hand end between the central pair of legs is shown a door 4, giving access to the central compartment 5 which serves for the passage of the pipesleading to and fromthe refrigerating coils.

A chamber is supported on the counter. This chamber is formed with front walls 6 at o posite sides and a top 7. It will be noted that the walls 6 do not extend up to the level of the top, nor does the top extend laterall to the planes of the Wall 6. Consequent y, at each side, an inclined opening 8 is formed through which access is obtained to the opposite sides of the chamber. Centrally of the chamber are located the refrigerating coils 9 which-extend referably close up to the top. In front of t e coils, at each side, are supported the screens 10, space being left between the bottom of each screen and the counter and between the top of each screen and the top 7,th1.s providing for air,

circulation. At the top of each wall 6 is secured an inwardlyA extending narrow shelf 11. The parts of the chamber 1n front of the coils form storage aces, and these storage spaces are preferab y divided by transverse partitions 12.

In practice it is desirable to form the walls 6, the ends and transverse partitions of the storage spaces and the parte ofthe top imwardly inclined mediately above the storage spaces of lato glass, thus facilitating the inspection o the contents of the storage space and adding to the attractive appearance of the refrigerator as a whole. The screens 10 are also preferably formed of mirrors which will reflect images of the goods within the storage spaces and give the appearance of greater depthto these spaces. j.-

Thefoperation of the refrigerator is as follows :@Warm air passes through openings above the screens 10 to the refrigerating coils. It is then cooled by these coils and drops to the bottom of the coil chamber, passing out through the openings under the screen into the storage s aces. The cold air then Hows along the ottom of each storage space and up the front where it encounters the shelf 11.v This shelf changes its direction of iiow towards the rear ofthe storage space, so that a tendency exists to keep the cold air eddying in the storage CANADA, ASSIGNOB TO LOBLAW space, thus checking its tendency to escape. i

can be conveniently placed 1n the storage` spaces of the refrigerator.

1. A refrigerator chamber having a top, bottom and walls and a rearwardly and'upopening in the top ad'acent the front; a shelf extending rearwardly from the front wall at the forward edge of the opening; a Hue containing refrigerating coils located at the back of the chamber and communicating with the interior of the chamber adjacent both the top and bottom thereof whereby warm air in the top of the chamber passes to the rear into the flue, is cooled, drops down, flows to the front, and is deflected rearwardly towards the upper end of the flue.

2. A refrigerator chamber having a top,

bottom and walls and a rearwardly and upwardly inclined opening in the top adjacent the front: a. sneu extending rearwardly from the front wall at the forward edge of the opening; and refrigerating coils located 5 at the back of the chamber remote from the shelf, said coils extending above the level of the forward edge of the aforesaid opening, whereby warm air in the top of the chamber passes to the rear, is cooled, drops down, flows to the front and is deiected l0 rearwardly to form a vertical eddy in the chamber.
