TJ all whom tt may concern;

le it known that we, EDWARD A. Coa- NILL'LE and CHARLES lf. ConNlLLm, citizens of the United States, and resident of Milwaukee, in the county ot' Milwaukee and State of Vfisconsin, have invented certain new and useful Improvements in Refrigerators; and we do hereby declare that the following is a full, clear, and exact description thereo-f.

Our invention has for its object to provide a refrigerator which is simple in construction, durable, sanitary and non-conductive, the object being attained primarily by an inner lining of vitreous slabs or glass.

Said invention consists in various peculiarities of construction and combination of parts as hereinafter described with reference to the accompanying drawings and subsequently claimed.

ln the drawings: Figure l represents a longitudinal sectional elevation of a refrigerator embodying the features of our invention, with portions of the view broken away, the section being indicated by line ll of the succeeding figure; Fig, 2, a transverse section of the same, as indicated by line of Fig. l, Fig. 3, a horizontal sectional view of said refrigerator, with parts broken away to better illustrate the details, the section being indicated by line 3 3 of Fig. 2, and Fig. et, a detail elevation of the skeleton frame, with parts broken away and parts in section.

Referring by letter to the drawings, A indicates refrigerator walls of ordinary construction, being composed of inner and outer wood casings spaced apart to receive the usual filling B of mineral wool or other nonconductive material. To the inner casing of the walls is fitted a metal-angle skeleton frame composed of upright corner-strips C, connected by a central horizontal metalangle truss D and similar trusses E, F/, respectively atthe top and bottom of the refrigerator. The lower flange of the bottoni truss E forms a support for a wood filling F upon which is preferably laid a sectional hollow tile floor G provided with a coating of cement a, the latter forming a bed for glass linino plates H, as best shown in Figs. l and 2 o the drawings. The side and rear walls of the refrigerator are lined with plates I of glass or other vitreous material, which plates are fitted and secured to the angle-iron frame in any suitable manner, the bottom edge of the plates of the cooling chamber being supported upon the cement a, while the top edges thereof abut the horizontal flange of the truss D and are held in place by a metal-angle strip Z2, the said truss serving as a keeper between the lining plates of the ice and cooling chambers. The lining plates l of the ice chamber are fitted to the angle-iron frame similarly to those just described with the eX- ception that the lower edges of these plates rest upon the upper face of fiange Z) of the central truss.

By the above described arrangement of lining plates it will be observed that a dead air space c is obtained between the inner casing of the refrigerator wall and said. plates, the air-space serving as a non-conductor to keep the glass lining at a uniform temperature.

In the accompanying drawings the cooling chamber is shown provided with a glass division plate J, fit-ted between the bottom lining plates H and rear wall plates l, the division plate however may be dispensed with in some instances, in which case the bottom lining would be in one piece. Tubes K are supported in the cooling' chamber between studs (Z which pass through the liange l) of the central truss, and dowel pins c projecting from the bottom lining plates, there being fingers formed on. said tubes for the reception of horizontal rods g upon which suitable shelves /L rest.

A n ice-tray L is supported upon two pairs of Z iron girders L which rest upon the flange Z) of the central truss, the lower flanges of said girders serving as rests for deflector board 2', which board protects the fioor of the ice-tray from Contact with the warm air rising from the cooling chamber that would otherwise strike the same and cause condensation, the consequences of which frequently result: in a wet and unsanitary condition of the cooling chamber. The icc-tray is provided with the usual ice-rack y', its floor being` `slotted to permit drainage, which is caught by a trough /c supported by the flange 7) of the truss frame, the trough being connected to a drain fm, projecting from the refrigerator floor by a pipe n, the lower end of which enters a flared mouth of said drain.

One of the most important features in refrigerator construction is to provide against shrinkage and wear at the door joints, which results in leakage of air, and thus prevents a perfect seal. lith this in view we have provided metallic door jambs operating in conjunction with metallic faced doors having dead air spaces between the saine, thereby obtaining a perfect seal in the following manner.

The front wall A of the refrigerator is provided with rectangular openings, to the edges of which openings are secured angleiron frames N, The vertical inner flange of each of the frames N has secured thereto a corres )onding flange of a Zshaped metal door jamb M, the flange of which jamb forms a shoulder about the four sides of the frame N. The web portion of the Z-shaped metal door jamb extends inwardly and bridges the space between the wall A and the interior wall of the refrigerator, which space is provided with the filling B. The interior iange of the Z-shaped metal .jamb M together with the exposed portion of its outer fiange forms a double seat for a Z- shaped metal binder frame P, having its vertical flanges arranged to abut upon the double seat aforesaid, the binder frame being secured to the sills Q of a hinged door of which it constitutes a part, and is of such proportion thatwhen the door is closed an air-space is formed between the web portion of the binder-frame and the web portion of the door jamb M. Each door is provided with a wood boxing R that is interposed between the inner flange of the binder-frame P and the door-sills Q, the boxing being closed front and rear by glass panels S, S', to form an airspace therebetween.

By the described arrangement it will be seen that the metallic skeleton frame serves as a support for the ice chest and all of the glass lining plates, and consequently any shrinkage or swelling of the refrigerator walls will not affect said lining or its joints, the said lining being entirely independent thereof, will remain intact during the life of the refrigerator, a result which could not be attained wherein vitreous lining is applied to, and dependent upon the walls for support.

le claim l. )i refrigerator having an opening therein, a continuous Z metal jamb fitted in the opening, a door for the saine, and a continuous Z metal binder frame for th door, said frame being of less dimension than the jamb, whereby when said door is closed the flanges of the door binder frame and jamb abut each other to form a continu'ous closed air space around the aforesaid door.

2. in a refrigerator having a wood-casing, a rectangular opening therein, an angle metallic facing for the opening, a Z-metal rectangular jamb fitted to the inner flange of the metal facing, the web of the Z-iron being of lesser dimension than said metal facing, the combination of a door for the opening comprising wood sills and boxing, vitreous plates fitted to the inner and outer edges of the door-boxing to form a dead airspace, and a Z-iron rectangular frame of lesser dimension than the Z-iron jamb, secured to the door sills, the flanges of the Z-iron frame adapted to close upon the flanges of the Z-iron jamb to foi-1n a continuous dead-air space between the webs of the respective Z-irons.

3. A refrigerator having an ineased skeleton frame comprising vertical angle-iron corner strips, the flanges of which are inwardly disposed, a set of bottom angle-iron truss-members secured to the flanged faces of the corner-strips, the horizontal flanges vof the truss-members being inwardly disposed, a flooring supported upon the inner horizontal flanges of said truss-members, a second set of truss-members, similar to the first named set, secured to the corner strips intermediate of their ends, a top set of angle-iron truss-members secured to the upper ends of the corner strip flanges, the horizontal flanges of which truss-members are outwardly disposed, side, back and bottoni plates of vitreous material fitted to the corner strips between the floor and intermediate truss-members of the skeleton frame, other side and back plates of vitreous inaterial fitted to the corner strips above the intermediate truss-members and adapted to be supported thereby, and a top plate of vitreous material supported by the last named set of side and back plates.

ln testimony that we claim the foregoing we have hereunto set our hands at Milwaukee in the county of Milwaukee and State of lVisconsin in the presence of two witnesses.
