Application filed February 2:, me. Serial no. 90,094.

This invention relates to refri household units, particularly of t used to refrigerate ice for table use, and an object of this being to provide a novel, and

crating highly efiicient non-complicated apparatus,

conveniently arranged to use prepared solidified carbon dioxide snow as the refrigerant. For further comprehension of the invention, and of the objects, and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claims in which the various novelfeatures of the invention are inore particularly set forth.

Referring to the drawing I which forms a part of this disclosure:

Fig. 1 is a horizontal sectional on the lime ll of Fig. 2. a

Fig. 2 is a vertical on the line 22 of Fig. l.

Fig. 3 is a top detailed view of tlielower drawer.

Fig. 4 is a modification illustrating the employment of means to aid in-the opening of the drawer.

Fig. 5 is a view similarto Fig. 1, but of a modified construction.

i of rectangular crosssection,'and at the upper central portion is provided with a' sunk-in portion 10 to support and house a receptacle inserted'therein, such as 11 formed with projections 11 from the sides therefor to obtain a clearance space between the walls of the receptacle and the housing 10. i

The refrigerant is placedsin the receptacle 11, and the refrigerant used is prepared so lidified carbon dloxide snow, which may be entered into the snow receptacle by eans of a nozzle entering into the mout 11", which thereafter is closed, said nozzle being connected to a supply of liquid carbon dioxide, with the necessary control valves in: terposed, The liquid carbon dioxide must be under a high pressure, and its expansion through the nozzle from high pressure to a -gasat atmospheric pressurea'refrigerates a certain portion into carbon dioxide snow.. The snow thus formed being /porous,

- then be compressed to 'obtain a may greater amount in-a giyen'spa'ce, to a density even greater than we. t x b Upon the absorption of heat by the snow it turns into a gas, and the receptaclell e type radiate the View taken ed within this chamber is a drawer 20, disectional view taken' 17 closed. The

is provided .with a plurality of apertures 11 in the side walls and bottom thereof, to allow the escape of the said gas. a v

The inner space of the housing 10, is partially filled with brine 14, which .surrounds the sunk-in? portions 10, to better coolness, and this brine may be entered by means of a suitable inlet pipe, and union indicated. at 15, the faucet 16 being provided at the bottom portion. of the housing holding the brine, to permit of removing the same.

It is known that heat rises, speaking coldness and relatively falls,

formed, which has a door 17, hingedas at 18, and at the upper end provided with lockmg means, 1ndicated'at'19. Slidably' mount vided by partitions 21 into a plurality of compartments opened at 'the top. Y

The drawer. 20 may he slid out, and these compartments filled with water, thereafter the drawer being reinserted, and" the door water may thus be frozen: into cubes of ice, which may be used for table purposes. I 1

lnithe modification illustrated in Fig. 4 means is provided to automatically pro ect the drawer 20 when the door 17 is opened,

the drawer 20' being of shorter length than v the housing so as to provide a space in the tached thereto against a flange 23, and an adjustable resistance formed by a flange '24 to which the spring is therefore in the bottom of the housing 10, a chamber 10 is .rear for the action of a spring 22, co-acting between the rear of the drawer, being. at-

tend the. full length of the device, and the brine being stored on both sides of the chamber in suitable compartments 10*;

The functioning of this device is very ob vious from the above description.- '1

While we have illustrated and described our invention with some degree of particularity, we realize that in practice various alterations therein may be made. We therefore reserve the right and privile changing the form of the details 0 con-- struction, or otherwise altering the arran ement of the correlated parts, without] ,e-

2 parting from the spirit or the scope of the appen (1 claims.

Having thus described our invention,

what we claim as new, and desire to secure by United States Letters Patent is 1. A refrigerator household unit, adapted to refrigerate ice for table use, comprising a housing of rectangular cross-section, havin g at the upper portion a sunk-in member, supporting a receptacle housing prepared solidified carbon dioxide snow, and provided with apertures to allow the escape of gas, said housing being formed with a brine chamber surrounding the sunk-in member, and a lower chamber, closed by a door, and housing a drawer with partitions to hold water to be turned into ice cubes, and means to project said drawer upon the opening of. said door.

2. A refrigerator household unit, adapted to refrigerate ice for table use,comprising a housing of rectangular cross-section, having at'the upperv central portion'a sunk-in member, supporting a receptacle housing prepared solidified carbon dioxide snow, and

provided with apertures to allow the escape of gas, said housing being formed with a brine chamber surrounding the sunk-in member, and a lower chamber, closed by a door,'and housing a drawer with partitions to hold water to be turned into ice cubes, and means to project said drawer upon the opening of said door, said means consisting of a spring acting between said drawer, and an adjustable resistance.

3. A refrigerator household unit, adapted to refrigerate ice for table use, comprising a housing of rectangular cross-section, having at the upper central portion a sunk-in member, supporting a receptacle housing prepared solidified carbon dioxide snow, and provided with apertures. to allow the signatures.

escape of gas, said housing being formed with a brine chamber surrounding the sunkin member, and a lower chamber, closed by a door, and housing a drawer with partitions to hold water to be turned into ice cubes, and means to project said drawer upon the opening of said door, said means consisting of a spring acting between said drawer, and an adjustable resistance, formed by a stud acting in a threaded aperture in said housing, and a co-acting lock nut.

4. A refrigerator household unit, adapted to refrigerate ice for table use, comprising a housing, a sunk-in portion provided in said housing, a receptacle housing prepared solidified carbon dioxide snow supported-in said sunk-in member, abrine chamber sur. rounding said sunk-in portion, a lower chamber formed in said housing, a door communicating with said lower chamber, a drawer formed with partitions housed in said lower chamber, and means to project said drawer upon the opening of said door.

5. A refrigerator household unit, adapted to refrigerate ice for table use,comprising a housing, a sunk-in portion provided in said housing, a receptacle housing prepared solidified carbon dioxide snow supported in said sunk-in member, a brine chamber surrounding said sunk-in' portion, a lower chamber formed in said housing, a door communicating with said lower chamber, a drawer-formed with partitions housed in said lower chamber, and means to project said drawer upon the opening of said door, said means consisting of. a spring. acting between said drawer, and an adjustable resistance.

In testimony whereof we have afiixed our JULIUS G. BURNS. HERBERT s, DAVIS.
