Definitions
- the said invention relates to a provision for preserving fruits and other perishable substances; and it consists of a room or apartment guarded externally by non-conducting walls, and provided at its upper part with an insulated ice-reservoir and within its interior with a means of mechanical agitation of the contained air, and with deposits of quicklime or other absorbents.
- Figure l shows by vertical section and in perspective a room or 'chamber embodying my improvements.
- 2 is ahorizontal section below the ice door.
- Fig. 3 is a perspective view of a portion of the ice-reservoir, together with one of its supporting beams.
- Fig. 4 is a transverse section ofa supportingbeam.
- the preserving-chamber J should be made as nearly air and heat tight asl possible, and
- E,f, and g constitute, respectively, an outer, an intermediate, and an inner air-tight shell or casing.
- the ice-ioor P is constructed of sheet metal, so as, while effectually preventing any ⁇ actual contact of ice with the air of the preserving-chamber J, to at the same time alford a free and eq ⁇ ual conduction ofheat through every portion of the loor.
- the upper surface of the ice-loor l) has a slight descent toward one or more discharge-pipes, Z.
- p is a rim supporting an inner wall, w.
- the ice-floor P is supported on transverse beams T, having their upper portion, metallic, in order that there may be a free and rapid conduction of heat from the preservingchamber through those ⁇ parts of the floor in contact with the beams.
- the lower portion, u o, of the beams may be ot' wood.
- y is a metallic trough to receive and conduct oli' condensed vapor.
- @O is a movable air-tight cover, which is made to tit snugly the, sides of the ice-reservoir, so as to insulate its lower portion, containing ice, from its upper portion, which, after placing of -the ice-cover O, is packed with chai orother In u-conductor.
- the insulation of the two compartments ot' the ice-reservoir may-be completed by the applicationof'tarred canvas or other luting to the edges of. the cover O.
- the elevation of the cover 0 for the insertion of ice may be effected by means of af windlass, W, and cord k or other suitable appliances.
- R is a door leadinginto the ice-reservoir.
- the entrance-passage to the preservingapartment should be guarded by a series of doors, so that an entrance to or exit from the room can be eected without direct com munica.- tion between the inner and the outer air.
- These doors should be made double, and be packed with chaif or other non-conductor, and should be made to lit their frames closely by means of list or otherwise.
- H are shelves for the reception of fruit or other edibles.
- Receptacle K is a rotary fan operated by ⁇ means of a wind-wheel, N.
- Receptacles F for quicklime or other suitable desiccating andantiseptic substance, act in conjunction with the agitator K to absorb gaseous impurities and surplus moisture from every portion of thc contained air.
