REFRIGERATOR.

Specification of Letters Patent.

Patented Oct. 19, 1909.

Application filed March 9, 1909. Serial No. 482,246.

To all whom it may concern:

Be it known that I, WILLIAM T. NIoHoLLs, of "Wellsburg, Brooke county, West Virginia, have invented a new and useful Refrigerator, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevation of a refrigerator embodying my invention; Fig. 2 is a section on the line IIII of Fig. 1; Fig. 3 is a section on the line IIIIII of Fig. 2; Fig. 4 is a vertical section showing one corner portion of the refrigerator on a larger scale; Fig. 5 is a horizontal section through one of the corners, also on a larger scale; and Fig. 6 is a detail plan View of a portion of the frame.

My invention has relation to refrigerators, and is designed to provide a refrigerator having its inner and outer walls formed of glass, and wherein the use of wood is wholly eleminated; also to provide a refrigerator of this character which will be thoroughly sanitary, in which there will be no screws, bolts, or other fastenings to work loose, and which can be constructed at a comparatively low cost. To this end my invention consists in the novel construction of the refrigerator hereinafter more fully described, and pointed out in the appended claims.

Referring to the accompanying drawings, in which I have shown the preferred embodiment of my invention, the numeral 2 designates the inner glass tile lining of the refrigerator structure, and 3 the outer tile covering. In the construction of the refrigerator, I make a base frame of the form shown in Fig. 6, consisting of the four metal strips 4 mitered together at their meeting ends and secured at the corners by means of the gusset plates 5 riveted thereto, these plates being preferably provided with the inner corner extensions 6, which may be utilized as a support for the caster bearings The base strips 4 are preferably provided with the vertically upwardly projecting flanges 7 at their inner edges. Upon this frame, T place a series of suitably spaced channel or I-beam members 8 as shown in Figs. 2, 4, and 5, and secure thereto in any suitable manner an inner and outer metallic lathing 9 of any suitable character, such as expanded metal. The space inclosed by the lathing may be filled as indicated at 10 with mineral wool, cork, or any other suitable heat-insulating material. I then apply to the lathing on both sides a coating 11 of cement, which forms a bed for the glass tiles forming the inner and outer surfaces of the structure. These tiles are preferably of a form having undercut projections 12 on their inner surfaces, which are embedded in the cement, and which secure the tiles firmly in place.

The floor of the refrigerator structure is preferably formed by a base plate 13 supported on the base frame 4, and forming a support for a cement bed 14 in which are set the fioor tiles 15. The interior frame formed by the members 8 and by the metallic lathing can be suitably reinforced at the corners, as by means of the angles 16 (see Fig. 5).

17 designates the usual doors for giving access to the interior of the refrigerator. The body of each of these doors is constructed in the same manner as the wall structure of the refrigerator, but each door body 1s surrounded by a metallic frame .18, which fits Within a corresponding frame 19 set into the wall structure.

. The frames 18 and 19 are preferably provided with the interfitting offsets or shoulders 20, which insure close seating of the doors when closed. These frames 18 and 19 may also be provided with the usual door fixtures, which, with the exception of the hinges, are not shown in the drawings.

The top of the structure is shown as formed in the same manner as the side walls, except that the members 8 in the side walls are shown as of channel form, while the corresponding members in the top wall are preferably of I-beam form, since these memhere are required to sustain the weight of the top wall. The top of the structure may be formed with a molding 21, as shown, since the glass tiles employed, together with the cement, may be molded to any desired form.

22 designate suitable shelfsupporting members. These can be secured to the frame members 8 or to the reinforcing angles 10, and the cement placed around them, their inner ends projecting through the inner tiles sufliciently to form shelf-supports. These supporting devices can be so arranged as to come between the joints of the tiles as shown in Fig. 3.

The construction described forms a very strong and secure construction, in which wood is entirely eliminated, and which can be manufactured at a comparatively low cost. The body of the structure consists mainly of cement, which permanently secures the interior and exterior tiles, and which, with the metallic lathing and frame members, constitutes a rigid wall structure. The only metal which is exposed at the exterior of the structure is that at the door frames and doors, and the base frame. There is, therefore, very little metal surface to become tarnished or to keep clean. It will also be noted that theuse of securing screws or bolts for holding the parts of the structure together is entirely eliminated.

It will be obvious that various changes can be made in the details of construction and arrangement of the parts. Thus, the inner metallic frame can be constructed in various ways; any suitable form of metallic lathing may be employed; and any desired character of glass tiles may be used.

What I claim is 1. In a refrigerator, a wall structure comprising separated metal supports forming a skeleton frame, inclosing an unobstructed space, a filling of non-heat-conducting material in said space metallic lathing secured directly to both sides of the skeleton frame, a layer of cement applied to the metallic lathin and tiles set in both the inner and outer Iayers of cement and forming the interior and exterior surfaces of the structure; substantially as described.

2. A refrigerator, comprising a bottom wall, consisting of an open base frame, 'a base plate supported thereby, a layer of cement on said plate, and tiles set in the cement, side and end walls consisting each of spaced upright supports resting on the base frame, metallic lathing secured directly to said supports on both sides, inner and outer layers of cement applied to the lathing, tiles set in said cement and forming both the inner and outer surfaces of said walls, and a top Wall of similar structure to the side and end walls; substantially as described.

3. In a refrigerator, a wall structure comprising a supporting frame composed of parallel spaced metalv pieces, metal lathing secured directly to each side of said supports, a fillin and non-heat-conducting material confine between the lathing, and tiles supported from the lathing and forming the interior and exterior surfaces of the structure; substantially as described.

4. In a refrigerator, a Wall structure comprising a supporting frame composed of parallel spaced metal pieces, metal lathing secured directly to each side of said supports, a filling of non-heat-conducting material confined between the lathing, and tiles sup ported from the lathin and forming the interior and exterior surfiaces of the structure, said structure having door openings therethrough, a fixed metallic frame seated in and surrounding the openings, and a door having a metal frame arranged to fit within the fixed frame, and a body portion of similar construction to that of the fixed portion of the wall; substantially as described.

5. In a refrigerator, a wall structure, comprising an inner metallic skeleton frame, inner and outer layers of cement applied to said frame, inner and outer tile coverings secured by the cement, and shelf-supporting members carried by the metallic frame and projecting through the inner layer of cement and the inner tile-covering at the joints between adjacent tiles; substantially as described.

In testimony whereof, I have hereunto set my hand. WILLIAM T. NICHOLLS.
