(Cl. 312-149) The present invention relates to improvements in refrigerated lockers. In particular, the present invention relates to improvements in a type of refrigerated chamber having a large number of open ends abutting against the inside of the hous ing. The end openings of the shells are arranged in alignment with the openings 6 closed -by the insulated doors l. Each shell 8 supports therein small compartments which may be rented sepa-_` a rectangular and elongated drawer 9 which has rately. to different people. its sides and ends closed as well as the top, with In the past, refrigerated lockers have been un the> exception »of a plurality of small openings satisfactory because in some instances the user having removable locker closures I0, each one of has. had his whole body subjected Vto the refrig which givesaccess to an individual locker.

Each of the drawers may posed openings, an elongated drawer adapted to slide endwise through said openings, a closure for 20 be supported upon . suitable rollers I2 placed thereunder and bearing at their ends in the side each of said openings, each of said closures being walls of theshell. `The rollers at the end of the larger than itsrespective opening and overlying shelll may 4have additional support and bearing said opening, and means for engaging each of said closures with either said housing or said 25 surface bythe provision of vertical uprights I3 placed alongside the ends of each tier 'of‘shells An end roller is, at times, called upon to support the total weight of the drawer. A top or hold above, and which will attainthe objects of the down roller i4 is provided and placed centrally present invention, are hereinafter described in detail and shown in the accompanyingdrawings 30 of the shell. This hold-down roller will prevent the inner end of the locker from tipping up as wherein: ' the other end is withdrawn.

This removing of only half of the drawer at a time by movement in either direction 6 even if the drawer is to be pulled in only one di rection, that is, it leaves the housing through only one opening. Having thus described the construction and op to either side of the housing, greatly simplifies eration of our device, we claim: the construction in that the strains on the drawer are greatly reduced and the problem of providing suitable rollers or bearings upon which the drawer moves is much simpler. This is particularly so, 10 in View of the fact that thesedrawers are loaded therein, a drawer supported within the housing for movement outwardly through said opening, a with weights of sixteen hundred pounds or more ' ‘ 1.
