ICE-CHEST 0R REFRIGERATOR.
Specification of Letters Patent.
Patented aan. e, fait.
Application led anuary 6, 1914'. Serial No. 810,538. f
To all whom t may concern:
Be it known that I, CELso PIAZZA, citizen of Italy, residing at 35 Rue Paradis, Marseille, inthe Republic of France, have invented new and useful Improvements in Ice- Chests or Refrigerators, of which the following is a specification. A
This invention has for its object an economical refrigerator or ice safe; the peculiar arrangement and insulation of' which enables the loss of ice to be reduced to a minimum.
Now referring to the accompanving drawings which show an example of t e application of the invention which may be considerably modified while still retaining the essential features of the invention; Figure 1 shows a view in perspective of the ice chest or refrigerator; Fig. 2 is a vertical longitudinal section; Fig. 3, a vertical transverse section; Fig. 4, a horizontal section; Fig. 5 is a view in perspective of the insulating envelop or casing containing the ice; Fig. 6 is a view of the air aspiration valve; Fig. 7 is a section of a portion of the insulating casing containing the ice; Fig. 8 is a view of one of the fans or propellers for changing the air.
The refrigerator is composed of a wooden chest or vsafe ha yg double walls A, between which Galician wood-charcoal B. is placed in the form of grains. In the middle of the charcoal and in order to render` Ycompletely impervious the walls of the refrigerator, a sheet of cardboard C coated on the inner side with a mixture of tar and niter is provided. The bottom of the ice chest or refrigerator is'occupied by a shallow zinc dish or pan D, intended to receive the water formed by the melting of the ice. This dish has a little siphon E which is closed by a few drops of water. In the center and against two sides of the ice chest, receptacles F containin the ice are placed. Each of these receptac es, the number of which may vary, is formed of a box divided into three compartments G H G; the parts G which are similar to one another are tightly closed and contain at the upper part a very sensitive valve I, held down by a spring and opening inward, and a very small screw propeller or fan J mounted on three gut cords K held taut by a spring L. A hole P is bored at the bottom of each of the compartments 'therefrigerator whence a G for the exit o-f air. The compartment H has on its two larger faces inclined strips S of wood to allow the vapor of the ice to escape. An inverted trapezoidal or truncated pyramidal form is given to this compartment H with the object of providing a greater cooling effect to the upper part of the refrigerator where the warmer air is always found. The interior of this compartment H is lined with a double cover of wool M, which is preferably formed into a removable envelo or casing adapted to receive the ice, and y tween the layers of which a mixture of wax and ireclay Q is placed in order to preserve thefice. Small holes N5 formed with a punch in this cover between the strips of wood enable the vapor to escape from the ice.
The ice is filled in at the upper part of the receptacles by lifting lids O and the top R of the casing M. After the ice has been placed in the receptacles and in proportion as the temperature descends, the gut cords K become tauter and cause the screw fans J to make several revolutions; the air contained in the upper part of the refrigerator or ice safe is then drawn through the sprin valves `and returned to the lower portion off portion can escape through the Siphon. The same movements are repeated automatically when the doors of the refrigerator or ice chestare opened and closed and the temperature rises due to the effect ofthe introduction of warm air. The slight stirring and washing of the air by the screw propellers also serve to produce a regular temperature both in the lower and inthe upper part of the refrigerator.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a refrigerator or ice chest, a casing for the ice comprising a double layer of wool, and an intermediate filling of clay and wax.
2. In a refrigerator or ice chest, a casing for the ice comprising a double layer of wool, and an intermediate fillingl of clay and wax, the walls of said casing aving holes wax, said casing having the shape of an nname to this specification in the presence of verte] truncafted pyramid as described. two subscribing witnesses.

In testimony whereof I have signed my BUCGHIENI JOSEPH.
