Description

July 21, V1931. M. .1: HEwlTT PORTABLE REFRTGERATOR Filed May 29. 1929 Gttorneg' Patented July 21, 1931 PATENT FFFEQCE PORTABLE REFRIGE'RATOR Application een .Mw 29,

The invention relates to la refrigerator cover vfor barrels and vother receptacles, and the present application is filed to take the place of an application tiled by me August 9,1928, Serial Number 298,585, for the same invention. y

The object of the present invention is to provide a simple, practical and eflicient f o-od receptacle cover of strong, durable and comparatively inexpensive construction, designedfor use lon barrels and other receptacles for theshiplnent of lislnpoultry, meats, .eggs Aand other perish-,able goods, and adapted to be readily applied to 'and-removed from a barrelwitheut injury to the refrigerator cover and capable of maintaining the entire contents `of the barrel lor other receptacle at the desired temperature, so thatsuch articles offood may be shipped without liability of spxoili'n g .them in transit.

A further object of Vthefinvention is to provide a refrigerator cover of xthis character adapted to be re-icedduring transit without removing it lfrom the barrel and capable of :draining the ice wat-er without permitting the same to come in contact'with the Voontents of the shipping receptacle.

Another object 4of the invention is to provide a refrigerator cover for barrels adapted t0 extend from the t0n t0 the -bottem Ote barrel and ,capable 'of Vfeeding ice by gravity from the top to the bottom, and equipped at the top with an ice-'hopper adapted to hold a relatively large amount'of ice s o that frequent re-icings will not be required.

` It is also an object of the invention to p.r ovide a refrigerator cover for barrels and ,other receptacles `adapted to be compa/ctly arranged for returning the device to the shipper and provided with means for `holding a'sliipping tag and capable of maintaining the tag in an exposed position both when the refrigerator oover'is in use on `a barrel and when in folded condition lfor returning the device to the shipper;

With these and other objects in View, the invention consists in the construction and novel combination and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and set forth in the 192,9. serial NQ. 356,950.

claims hereto appended, it 'being' understood that various changes in the form, proportion, and minor details of construction, with'- in the scope of the claims, may be resorted to without departing from the spirit'of lthe in Vention or sacrificing any of the-*advantages thereof.

In' the drawings `Figure l is a perspective view of a ref-rigerator `cover for barrels constructed'in'accordance with this invention and lshowing the cover-attached to the barrel.

Fig .`2 is ar centralvertical sectional 'view of the same. i

Fig. 3 is a side elevation of the refrigerator cover, thelower portion of the-metal tubular section being broken away and the upperpart of the flexible section being in section.

Fig. 4 is a. side elevation, partly in section, showing the refrigerator device inV folded position'.

Fig. 5 is a detail sectional view illustrating the manner of securing theV refrigerator device in folded position.'

ln the accompanying drawings, in'which is illustrated the preferredv embodiment of the invention, the refrigerator cover comprises in its construction a lower tubular metallic section l and an upper flexible section 2 constructed of canvas or other suitable yfabric and adapted to be collapsed and folded andjarrangedfwithin the lower tubular section l forreturn to the shipper or other person, as illustrated in Fig. lof 'the drawings.

The lower sectionl consists of-a pipe or tube of iron or-other suitable material, and it may b e tapered and cylindricalin cross section, as l illustrated in lthe accompanying drawings, or of any other desired configuration, vas will bercadily understood, and when thedeviceis in use it is arranged withina barrel 43 and extends fromthebottom of the'barrel to the upper portion thereof, as clearly illustrated in Fig.y 2 ofthe,drawings.r The lower end of t-he tubular section l is secured to the vbottom 4 ofthe barrel by being arranged in an opening 5 thereof. The tubular section 'is provided atits lower end with a bottom wall 6 having .perforations 7 forming drain openings and adapted to permit Ithe ice water to drain from the device without emptying the barrel or coming in contact with the contents thereof. The side walls of the tubular lower section are imperforate between the bottom of the barrel and the upper flexible section so that the ice water cannot leal; or pass into the barrel.

The flexible upper section 2 has a tapered lower portion S extending downwardly from the top of the barrel and terminating in a substantially cvlindrical neck 9 which is secured within the upper end of the tubular section 1 by suitable lacing 10 which passes through spaced perforations 11 of the tubular sectionA 1. rlhe extension neclr 9 covers the perforations 11 and closes the saine at the inner face of the tubular section 1 and prevents any leal;- agc of water through the said ierforations. The flexible section 2 may, however, be secured to the lower tubular section in any other desired manner7 as will be readily understood. The upper portion of the liexible receptacle extends normally above the top of the barrel, as clearly illustrated in 1 and 2 of the drawings, and is substantially cylindrical, the side walls being preferably arranged at a slight inclination and defining a slight taper, but the normally proj ecting upper portion of the flexible section of the device may be of any other desired configuration, and it is provided with a horizontal top wall l2 composed of two substantially semi-circular sections having diametrically arranged contiguous edges 13 provided with suitable eyelets 1a receiving a suitable lacing 15 which is adapted to enable the refrigerator cover to be readily opened and re-iced in transit without removing the refrigerator cover from the barrel 3.

The enlarged flexible upper section of the device forms an ice hopper and is adapted to hold a considerable quantity of ice for enabling the contents of the barrel to be maintained in the desired temperature without frequent re-fillings of the device. rl`he diameter of they enlarged upper section of the .refrigerator cover is designed to be slightly less than that of the top of the barrel,v and it is provided with a flaring apron 16 of canvas preferably formed integral with the adjacent portion of the upper flexible-section and connected with the same by a substantially horizontal portion 17 which extends from the juncture of the tapering porn tion S and the upper projecting portion of the flexible hopper section of the device. The flaring apron conforms generally to the .taper of the upper portion of the barrel, as

clearly shown in F ig. 2 of the drawings, and it is secured thereon by a barrel hoop 18 which tightly clamps the apron on the barrel at the upper edge thereof. The flexible upper section of the device is providedat intervals with tabs or ears 19 having eyelets 2O through which are driven nails 21 or other suitable fastening devices which terminate short of and do not pierce the apron 16, as clearly illustrated in Fig. 5 of the drawings.

The refrigerator cover is provided at the top with a projecting ear 22 having a suitable eye 23 and adapted to receive a shipping tag 2li and capable of exposing the shipping tag when the refrigerator cover is in use and also when the flexible upper section of the refrigerator cover is folded and arranged within the tubular metal section 1, as illustrated in F ig. l of the drawings.
