SPECIFICATION forming part of'Letters Patent No. 236,851, dated January 1- 8, 188 1. Application filed .August 25, 1880. (No model.)

To all whom it may concern Be it known that I, JAMES SIMMONS, of St. Louis, in the county of "St. Louisand State of Missouri, have invented a new and Improved 5 Ice-Box; and I do hereby declare that the following is afull, clear, and exact description of the same.

The object of my invention is to construct the main frame and walls of an ice-box or refrigerator so as to be readily put together or detached for shipment, at the same time formin g asubstantial air-tight refrigerator; and the improvement consists in the peculiar construction of the corner-posts and sills and their ar- I 5 rangement with respect to the double walls of the box, as will be hereinafter more fully described.

In the accompanying drawings, Figure 1 is a perspective view of the ice-box Fig. 2, a transverse vertical section of the same; Fig. 3, a perspective view of a portion of a corner joint; and .Fig. 4, a similar view of a portion of the sill, showing the form of the joint.

The main box A may be arranged upon the 2 5 interiorin the usual manner, and provided with adoor, B, at one end, that is fitted into the easin gto form an air-tigh t joint therewith. A platform, 0, formed with a zinc bottom, and drainpipe 0, leading from it, is arranged in one cor- 0 nor of the box A at the farthest end of the box from the door, and is elevated some distance from the ground. The platform is partitioned 011 from the main compartment of the box by slats D, so that a free circulation of air betweenthe space above the platform and the other portions of the box may be obtained. A small door, E, is fitted into the casing opposite the space above the platform 0, through which the ice may be passed into the box and placed upon the platform. The casing of the box A is extended at one corner to form a small rectangular compartment, F, annexed to and communicatingwith the main compartment or box A. A partition,- G, of rectangular shape, is

arranged to slide between hollow walls of the box A, and is connected with a door, F, coverin g the compartment F,by means of -a string or cord, H, that passes over a roller, H, in the main walls of box A, so that when the door F is raised the partition G will be allowed to drop andshut 0E communication between the maincompartment or box A and the annexed .rents of air from the outside to rush in and reduce the temperature in the main compartment.

The walls and framing of the structure are built up in a peculiar manner, as follows: The sill and cap pieces may be of similar form and construction. The main sill-piece I is formed from a rectangular oblong piece of timber. It is beveled at i, on its upper and outer edge, and is grooved at 11in the middle portion of its upper face. A tenon or tongue, 6 is formed on its inner and upper side to constitute a bearing for a double floor, so that the under side of the lower floor will be flush with the under side of the sill-piece. The sill-pieces are formed of sides that are miter-jointed at the corners, so that the groove 6 in one sill-piece will communicate with the corresponding groove in the other sill-piece.

Each corner of the structure is provided with corner-posts K L. The post K has two tongues, k it, one formed upon each end. The one extending outward from the corner k forms a bearing to which the inner and outer, walls of the box A are fastened,'to leave an airspace, M, between them, and the other tongue, k, of the post fits tightly into a groove cut into the post L, the said tongue or tenon It being cut in line with the inner wall of the box to form a flush joint with the inner side of the post. The post L has a groove, 1, cut in its face, into which the tongue of the post K fits snugly, and has a tongue, I, out upon its end to extend outward from the corner to form a hearing, as in K, for the outer walls of the box A and annexed compartment F. Screwbolts N are run through post L, so that they will pass through the tongue k of post K to 100 secure the two posts, with their connections, firmly together. A filling-piece, a, is secured between the outer walls, a a, at their lower edges, to project downwardly therefrom and fit snugly into the groove 6 in the sill and cap pieces. The posts K L are each also provided at their ends with a tongue in line with and equal to the thickness of piece a and inner wall, a, which tongue fills up the groove 1' at 10 the corners. The inner sides of the walls a a are covered with non-conducting material.

The advantages of the mode of connecting the framing and walls of the box will be readily understood, and combine simplicity, strength,

and perfectly air-tight joints.

What I claim as new is 1. The framing of an ice-box or other compartment, formed with non-conducting walls, and consisting of the post K, formed with tongues k k, and the post L, formed with a tongue, l, and a groove, l, to receive tongue k, the tongues k and I being secured to and interposed between outer and inner walls of the structure, substantially as described.

2. The framingof an ice-box or non-conduct- :5 ing compartment, consisting of the posts K L, formed with tongues upon their lower ends, outer walls, a, inner walls, a, filling-piece a, and acap or sill piece, I,formed with groove '5, to receive the tongues upon the lower ends of posts K L, and tongue 1?, upon the upper and inner side of the sill-piece I, to receive the outer and inner parts of a double floor, in the manner and for the purpose substantially as described.

JAMES SIMMONS.
