REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 489,247, dated January 3, 1893.

Application filed August 15, 1892. Serial No. 443,126. (No model.)

To all whom it may concern:

Be it known that I, JOHN M. CLARKIN, a citizen of the United States, residing at St. Paul,

in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Refrigerators, of which the followingr is a specification.

This invention relates to refrigerators, and it consists in the construction, combination, and arrangements of parts, as hereinafter shown and described, and specifically pointed out in the claim.

In the drawings-Figurelis a cross sectional elevation. Fig. 2 isa longitudinal sectional elevation, on the line a' .fr of Fig. l, of a portion of one end of the refrigerator through the ice receptacle, and Fig. 3 is a front elevation of a portion of the other end, showing the arrangement of the doors. Fig. 4 is a plan view in section on the line y y of Fig.

l. Fig. 5 isa plan View in section on the line e e' of Fig. l. Fig. 6 is an enlarged sectional detail illustrating more fully the construction of the butter receiving chambers. Fig. 7 is an enlarged detail illustrating the manner of constructing the Walls of the refrigerator.

The casing or walls of the refrigerator are formed of an outer shell A having a lining fi of paper or other similar suitable non-conducting material, and an inner shell A2 placed some distance from the outer shell, as shown, so as to leave large air spaces between the two shells. This inner shell is also provided with a paper or other suitable non-conducting lining t2 the two shells being secured at the corners by corner posts A3, as shown.

Attached to the interior of the outer shell A at suitable intervals are wooden strips i* to form supports for a paper or other similar suitable non-conducting partition i, while strips i similar to the strips i4 are attached to the inner shell opposite to and projecting toward the strips i4- as shown, so as to form additional supports to the partition By this simple arrangement the walls are formed with two distinct and separate air spaces, which insures a much more complete and perfect insulation and at a very slight cost. This construction also greatly decreases the weight, as no heavy non-conducting tillin g is required for the walls.

The ice receptacle consists of a galvanized iron or other suitable pan B suspended about midway across the interior of the refrigerator, and provided with an ice rack B2 upon which the ice rests. The pan is surrounded on all sides by upright guards B3 forming racks to retain the ice in place but with sufficient space between them to afford free circulation of the air, as indicated by the arrows, in Figs. l-2 and 6. The ice `rack B2 is elevated a short distance above the bottom of the pan B by cross strips a, so that the water from the melting ice will freely flow off through the drainage tubes, as well as to permit the air to freely circulate around the slats, of which the rack is formed. The rear edge of the ice pan does not extend to the back of the interior of the casing, but ends at an interior non-conducting partition AAL which in turn ends a short distance below the top of the casing, so as to afford a passage for the air currents at b, as shown in Figs. l and 2. The lower edge of the partition A4 comes flush with the bottom of the pan B', as shown. Depending from the bottom of the pau B near its front edge, is a stop strip g which serves as a check to the rising warmer currents of air and prevents them from flowing upward against the descending currents of colder air flowing downward in front of the ice receptacle, but which causes them to flow backward and upward behind the partition A4. The front edge of the pan B does not extend to the front of the casing but space is left for a series of slatted shelves D', access to which is had through doors D2 in the front of the casing A, as shown.

In the front of the interiorof the casing beneath the line of the pan B', are a series of small compartments Fforined by short cross partitions F2, (see Fig. 4.) and each provided with an inner hinged door F3 and an outer hinged door F4, the latter formed with suitable nonconducting walls, preferably with two plates of glass cl d? and with an airspace d3 between them. The tops of these compartments are formed of slats e', and with a corresponding slatted grating over each with its slats c2 registering with the slats e', so that when the slats e2 of the gratings are placed above the slats e', currents can freely pass downward between them into and through the compartments F', as indicated by the arrows in Fig. 1, but when the grating is moved so that its slats e2 come above the spaces between the slats e', as in Fig. 6, the grating forms a cut of plate to shut off the air currents. Each ot` the doors F3 is connected to its corresponding door F4 by a rod h', so that as the door F4 is opened the connected door F3 will be closed, and vice versa, and by connecting each of the gratings to its contiguous door F3 by a short rod h2, the slats e2 of the latter will also be closed over the spaces between the slats e at the same time that the door F3 is closed, as in Fig. 6. By this simple arrangement, when one of the doors F4is opened all communication between the interior of the compartment F with which it is connected and the interior of the refrigerator, is shut off automatically, so that no substantial portion of the cold air of the interior of the refrigerator is lost by the act of opening one of the compartments F', all the cold air that is lost being that contained in one of the compartments.

posed of corresponding slats e2, and adapted.

to be actuated by the opening and closing of said doors, to cover and uncover the spaces between the slats forming the top wall of said compartments, substantially as and for the purpose set forth.

In testimony whereofI have hereunto set my hand in the presence of two subscribing witnesses.

JOHN M. CLARKIN.
