REFRIGERTOR SHIPPING-@ASE SPECIFICATION forming part of Letters Patent No. 608,701, dated August 9, 1898. Application filed October l, 1896. Renewed April, 1898. Serial No. 676,593. (No model.)

To all whom t may con/06771,:

being had to the accompanyingr drawings, and

to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in refrigerator shipping-cases, and has for its object to provide acase for transporting perishable articles in which the parts are so constructed and arranged as to give the best results with ecomomy of space and simplicity and cheapness of construction, the device comprising an inclosing case or receptacle having openings in the top and bottom, within which case or receptacle is located an inner receptacle presenting two compartments with a removable ice-box interposed between them and forming the inner side walls thereof, said ice-box having a spring-supported false bottom, a space for the circulation of air entirely surrounding the inner receptacle, and openings which register with the openings in the inclosing case to secure a proper circulation conduced by a peculiar arrangement and organization of the several parts; and with this end in view the invention consists in the special construction and combination of the parts, as will be hereinafter fully set forth, and pointed out in the claims.

In the accompanying drawings, forming part of this speciiication, Figure l is a vertical longitudinal sectional view through a refrigerator shipping-case constructed in accordance with my invention, and Fig. 2 is a transverse sectional view on the line 2 2 of Fig. l.

Referring to the drawings, A designates the inclosing case or receptacle,which is provided with a cover A', handhelds a at its ends, and feet a', which support the devicea suitable distance above the door. Within the inclosing case .A is located an inner receptacle B, which is provided on its four sides with projections or pins Z), covered by rubber tips D', said tips bearing against the inner sides of the case A to position the receptacle centrally therein. By this arrangement a'space a2 for the circulation of air is provided which entirely surrounds the inner receptacle B.

To the inner side of the side pieces of the receptacle B are secured vertical angle-stri ps d, presenting iianges or guide-rails which engage the ends of an ice-box O, said ice-box dividing the receptacle B into two compartments D D, which communicate with each other by way of a space left below the icebox by supporting the same upon feet c, formed by projections and rubber tips similar to those hereinbefore mentioned. W'ithin the ice-box O is a plate or false bottom C', supported upon helical springs c'. The ice is `placed upon the plate or false bottom C,

and as the ice melts it will be raised by the tension of the springs above the water or drippings which collect in the bottom of the ice-box. This provides for keeping the ice out of contact with the water, as the plate or false bottom moves upward automatically as the weight of the ice is reduced by melting.

A cover E is provided which fits over the top of the inner receptacle B to close the compartments D and ice-box C, said cover being provided with a central opening e, through which the air may pass from the ice-receptacle into the'air-space a2 when the temperature is lower therein than in the ice-chamber, and when the temperature outside is lower than in the shipping-case cold air will pass through 'the openings e4 and e into the icechamber. l/Vhen the conditions are reversed, the air will pass out of the openings e into the upper air-space a2 and will descend, passing out of the opening e3. Generally speaking, the circulation will be through the opening e2 into the compartments D upwardly and out of the openings e', the warm air rising and passing ont of the opening e4, While the cold air descends and is then carried upwardly by the inflow of air through the opening e3. Thus a constant supply of fresh air takes the place of that which passes out of the opening e4. This circulation is necessary when shipping articles that would otherwise foul the air if confined in the compartments; but in shipping bottled goods such circula- IOO tion would not be required. The openings e3 and e4 may be provided with Stoppers of ordinary construction for closing them when desired.

The construction herein shown and described provides a very simple, cheap, and effective refrigerator shipping-case in which perishable articles may be transported Without fear of spoiling, and by proper attention the air within the case can be maintained at a uniform temperature, which is very necessary in transporting certain classes of articles. It Will be noted that the ice-box O forms a side of each compartment D, and thereby offers the best results in cooling the air Within said compartments.

If desired, the device can be placed within a wooden box to better retain the cold air, and, in fact, the inclosing case could be made of wood instead of metal.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is-

l. In a refrigerator shipping-case, the combination of the inclosing case A, having a cover with a central opening e4, an inner receptacle l5, having openings e near its upper end, and a cover with an opening e", projections or pins covered by rubber tips carried by the receptacle and cover which bear against the case to provide spaces a2 by locating the receptacle centrally therein, vertical strips or guides d secured to the inner side of the side pieces of the receptacle I3, a removable ice-box C, placed Within the receptacle B, to bear at its ends against the guides or strips cl and provide two compartments D, D; together with helical springs resting upon the bottom of the ice-box C, and a plate or false bottom C mounted on said springs, the bot tom of the inclosing case having a central opening e3 said opening and the opening e4 being normally closed by Stoppers, substantially as shown.

2. In arefrigeratorshipping-case, the coinbination 0f an outer casing with legs or supports, the same having in the top and bottom openings, of an inner receptacle with projections to hold the same away from the inner walls of the outer case, said inner receptacle having vertical strips, central openings in the top and bottom of said receptacle, so disposed as to be on a line with the openings in the top and bottom of the outer casing, and openings near the upper edges of the side walls, together With a central ice-receptacle which engages with the vertical strips, the bottom of the ice-receptacle having legs or projections to engage the bottom of the inner receptacle, and a spring-supported traycarried by the ice-receptacle substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.
