1 Claim. 1

In rural communities it has long been a problem for the individual to preserve his meats and other perishable products.

Where there are sufficient persons in a community this problem may be solved by a central refrigerated depot. Such depots have been ice houses or cold storage places. These types of refrigerated depots required the individual to enter the refrigerated area.

It is among the objects of my invention to provide a refrigerated locker construction in which the drawers are accessible from the exterior, so that the user does not have to enter the cold area. My drawers are so constructed that when they are closed a seal is formed, preventing cold air from escaping, or warm air from entering. My sealing construction also provides a leakproof closure, and has such other objects, advantagesand capabilities as will later more fully appear and which are inherently possessed by my invention.

While I have shown in the accompanying drawings a preferred form for my invention, yet I wish it understood that the same is susceptible of modification and change without departing from the spirit of my invention.

Referring to the drawings, Fig. 1 is a perspective view of the exterior of my drawer, and Fig. 2 is an enlarged fragmentary view of my drawer, partly in section.

In the embodiment selected to illustrate my invention drawer I9 is slidable in the cabinet of a refrigerated locker system and withdrawable by the user without the user having to enter the chilled interior of the cabinet.

My drawer l9 consists of a drawer head 20 and to the rear a container portion 2|. The drawer head 20 has a front faceplate 3|, and s aced rearwardly therefrom a rear member 32. Extending rearwardly from front faceplate 3! are extensions 10 against which rests a continuous gasket 35 of rubber, canvas or other suitable flexible and sealing material. The front portion of breaker strip 33 rests against said gasket and screws II extend through strip 33, gasket 35 and extensions 10, to hold the strip 33 to front member 3!.

The o posite ends 12 of rear member 32 extend outwardly. Another continuous gasket 36 similar to gasket 35, rests on said ends 12. The rear portion of breaker strip 33 rests against said gasket 36 and screws H extend through strip 34,-

gasket 36 and ends 12, to hold the strip 33 to rear member 32.

The breaker strip 33 is therefore attached to front faceplate 3| and rear member 32 and closes the space therebetween which may be filled with heat resistant, insulating material. The breaker strip 33 is a heat resistant, non-conductor member, made of rubber, plastic or other suitable material.

Having thus described my invention, I A hollow leak-proof closure for refrigerated lockers comprising a head portion having a front faceplate, and extensions extending rearwardly from said front faceplate, said extensions spaced inwardly from the outer ends of said front faceplate, an unbroken continuous gasket resting on said extensions, said gasket having an enlarged, solid head portion engaging the rear of said front faceplate, a rear portion rearwardly spaced from said front faceplate and having its opposite portions bent to form outwardly extending ends, another unbroken continuous gasket positioned on said ends, and having an enlarged, solid head portion, a load sustaining non-conductor breaker strip extending between said front faceplate and said rear portion, said breaker strip having recessed front and rear portions, said front recessed portion engaging said first mentioned gasket throughout its length, the front end of said front recessed portion engaging the rear of the head of said first mentioned gasket, said rear recessed portion of said breaker strip engaging said last mentioned gasket throughout its length, the rear end of said rear recessed portion engaging the front end of the head of said last mentioned gasket, and means extending through said breaker strip and said gaskets for holding said breaker strip to said front faceplate and said rear portion to provide a sealed closure.
