HAM INMAN, OF KEOKUK, IOWA.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 718,767, dated January 20, 1903.

Application filed August 5,1902.

f0 all whont it 71m concern.-

Be it known that I, HAM INMAN, a citizen of the United States, and a resident of Keokuk, in the county of Lee and State of Iowa, have invented a new and Improved Refrigerator, of which the following is a full, clear, and exact description.

This invention relates to improvements in refrigerators; and the object is to provide a refrigerator so constructed that there will be a complete and continuous circulation of air between the storage chamber and icechamber, thus keeping the refrigerating-air at a cool and practically even temperature.

I will describe a refrigerator embodying my invention and then point out the novel features in the appended claim.

Reference is to be had'to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a refrigerator embodying my invention. Fig. 2 is a section on line at ocof Fig. 3. Fig. 3 is a section on line y y of Fig. 2, and Fig. 4 is a section on line 2 z of Fig. 3.

Referring to the drawings, 1 designates a storage-chamber for articles to be kept cool or refrigerated. This chamber or chest is arranged within an outer casing 2, and the space between the front and rear of the chamber 1 and the ends thereof forms an air-chamber 3, and an air space or chamber 4 is formed between the bottom of the chamber 1 and the bottom of the outer casin The storage-chamber 1 is provided with covers 5, and the end walls are provided withopenings 6, through which air may pass to the outer air-chambers. This storage-chamber is extended horizontally, and mounted thereon is an ice box 7. This ice-box is arranged with an outer casing 8, and the space between the rear wall of the ice-box and the outer chamber provides an air-space which communicates with the ice-box through an opening 9 at the upper end of the back wall of the ice-box. Arranged in the ice-box is a removable grate 10, on which ice is designed to be placed. Secured to the upper side of this grate and extended from the front end to about the center is a metal plate 11, while connected to the lower side of the grate and extended from about the center to the rear end is another plate Serial No. 1 1 8,46 3. (No model.)

12. These plates will catch the water from the ice and discharge the same into a trough 13, from which a pipe 14 leads outward. The space between the slats of the grate 10 and the plates 11 and 12 will permit of a free circulation of air. Arranged below the grate 10 is another grate 15, on which articles to be cooled may be placed. The ice -box has a door 16, and the compartment having the grate 15 is provided with a door 17. The airspace at the rear of the ice-box and the lower compartment thereof communicate with the air-spaces around the storage-chamber 1, as clearly illustrated in the drawings.

While I have shown the storage box or chamber as extended at both sides of the icebox, it is to be understood that it need extend only at one side, depending, of course, on the size of the refrigerator desired.

In the operation the air, which is somewhat warmed by the articles in the storage-chamber 1, will pass out through the opening 6 and thence through the several air-passages and through the opening 9, and this warm air will cause the cold air from the ice to pass downward through the grates 10 and 15 into the storage-chamber, and when this new supply of cold air becomes warm or heated it will pass out through the opening 6 and force more cold air into the storage-chamber, and thus a continuous circulation of air will be maintained, so that the air in the storage-chamber or box will be kept at a comparatively even temperature.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a refrigerator, a storage-chamber, an icebox, a grate comprising bars, a plate secured to the upper side of said bars and extending from the front to about the center, another plate secured to the under side of the bars and extended from about the center to the rear end, and a trough for receiving water discharged from the plates.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

HAM INMAN.
