SPECIFICATION forming .part of Letters Patent No. 300,351, dated June 1?, 188%.

Application filed March 20, 1884'. (So model.)

To all whom, it may concern:

Be it known that 1, Isaac T. DYER, of Quincy, in the county of Adams and State of Illinois, have invented a new and Improved Refrigerator, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved refrigerator, in which the openings through which the cold air can pass from the ice-chamber into the refrigeratingchamber, or the hot air can pass from the refrigerating-chamber to the ice-chamber, can be regulated at will, and which refrigerator can easily be taken apart for packing and cleaning.

The invention consists in a refrigerator having its ice-rack. formed of a series of verticallymovable troughs or gutters, over which inverted troughs or gutters are held, the inner ends of the troughs projecting over the sides of a gutter formed on the top of a transverse beam, from which an outletpipe extends to the bottom of the refrigerator.

The invention also consists in parts and details and combinations of the same, as will be fully described and set forth hereinafter.

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

Figure 1 is a longitudinal sectional elevation of my improved refrigerator. Fig. 2 is a cross-sectional elevation of the same on the line a: :22, Fig. 1. Fig. 3 is a sectional plan view of the same, a part of the gutter being removed and parts being broken away. Fig. 4 is a longitudinal view of the end of the shaft for raising the gutters. Fig. 5 is a cross-sectional elevation of the same. Fig. 6 is a side view of the device for locking the ice-rack in place. Fig. 7 is a cross-sectional elevation of the top gutters of the ice-rack. Fig. 8 is a longitudinal sectional elevation of the same. Fig. 9 is a sectional view of the bottom gutters of the ice -rack. Fig. 10 is a longitudinal sectional elevation of the same.

The refrigerator consists of a box, A, divided into an upper mach-amber, B, and a'lower refrigerator-chamber, 0, arranged below the ice-chamber. At the middle of the length and height of the refrigerator a transverse beam, 1), is arranged, in the upper surface of which a gutter or trough, E, is formed, which gutter is lined with zinc. In circular apertures in the sides of the beam D and crosspieces F, secured to the inner surfaces of the ends of the refrigerator at the same level with the beam D, the ends of two central longitudinal shafts, G, are journaled, which shafts also pass through apertures in intermediate crosspieces, H, arranged between the central cross-piece, D, and the end pieces, F. Each shaft G is provided with a semicircular notch, I, at each end, or in place of the notch, with a cam. That part remaining in the shaft after the notch has been cut out also acts as a cam. Adjoining each intermediate cross-piece, H, a handle, J, is pivoted in each shaft G in such a manner that the handle can be folded against the side of the cross-piece H, which cross-piece H is provided in the corresponding side with an inclined recess, K, for receiving the handle J. On each side surface of the middle cross-beam, D, and on the outer side of the surface of the end cross-pieces, F, fiat strips L are held by pintles L, passing through vertical slots L in the said strips, thus permitting the said strips to be moved vertically, the slots limiting their movement. The pieces or strips L are provided with notches 1, through which the ends of the shaft pass. If the upper ends of the pieces L rest in the recesses I of the shafts G, the said pieces L will be lowered; but if the shafts are turned on' their longitudinal axis, so that the round or cam parts of shafts rest against the closed ends of the notches, the pieces L will be raised-that is, the strips or pieces L can be raised or lowered by giving the shafts G about a quarter-turn, more or less. After the said shafts have been turned, the handles J are pressed into the notches K for the purpose of locking the pieces in place, as

shown in Fig. 6. In Fig. 5 the pieces L are represented as lowered, and the position they occupy when raised is shown in dotted lines. Gutters or troughs M, lined with zinc, are placed on the upper edges of the intermediate pieces, H, and on the upper edges of the strips L L, the said gutters being parallel with the longitudinal axis of the box. The said guttors are separated by blocks m on the upper surfaces of the middle cross-beam, D, and the end cross-beams, F. At the ends projecting over the gutter in the cross-beam D the gutters M are providedwith downwardly-proj ecting aprons M, made of zinc. Gutters or troughs N, covered on their top and bottom surfaces with zinc, and provided in their recessed surfaces with blocks 0, also covered with zinc, are placed over the spaces between the gutters M in an inverted position, so that the blocks pass in between the upwardlyprojecting sides of the gutters M, and the sides of the inverted gutters N lap over and are withinthe upwardly-proj ecting sides of the gutters M, as shown in Fig. 2. The upper surfaces of the inverted gutters N will then be higher than the gutters M. The inverted gutters N form the support for the blocksof ice,

and are in turn supported by the gutters M. The water produced by the melting of the ice flows over the sides of the inverted troughs or gutters N into the gutters M, and through the same to the gutter E in the cross-beam D, and then flows down through the outlet-pipe Q into a basin placed below the refrigerator, which outlet-pipe is provided with a series of apertures, It, through which the hot air in the refrigerator-chamber, through which the said pipe 0 extends, can pass. The ice-chamber is provided with a suitable door, and the walls are made hollow or filled in with non-conducting material, and the walls or sides of the refrigerating-chamber can be made of glass or of wood, as may be desired. The ends of the inverted gutters or troughs N rest on the blocks m. If the shafts G are so turned that the pieces or strips L are lowered, slots or longitudinal openings will be formed between the end edges of the sides of the inverted gutters N and the upper surfaces of the gutters M, as the inverted gutters N cannot be lowered; but if the shafts G are turned to raise the pieces L of the upper surfaces of the gutters M, will be pressed against the longitudinal edges of the sides of the inverted gutters N, thus preventing the cold air from passing into the refrigerating chamber. By means of the shafts G the ice rack or support can thus be adjusted to permit the cold air to pass from the ice-chamber into the refrigerating-chamber, or to permit the hot air to pass from the refrigeratingchamber to the icechamber; or the rack can be adjusted to prevent such a circulation of air. If the openings in the rack are all closed to prevent the hot air from passing into the ice-chamber, the hot air-can pass out through the aperture R in the outletpipe Q.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. A refrigerator provided with a rack formed of vertically-movable troughs or gutters, over which fixed troughs or gutters are held, the said lower gutters being arranged to close the spaces between the upper gutters, whereby communication between the two chambers may be shut off, substantially as herein shown and described.
