057% iii W B. B. BANKS.






To all whom it may concern:

Be it known that l, BENJAMIN B. BANKS, a citizen of the United States, residing at Chicago, in the county of Cook and State of llllinois, have invented a new and useful Refrigerator, of which the following is a specification.

My invention relates to improvements in. refrigerators in which adjustable, revolving sectional shelves are employed in conjunction with a ventilating system creating a constant circuit of air. The objects of my improvements are:

1st. To render access to and removal of food and other contents from the refrigerator more convenient, expeditious and safe. Heretofore it has been necessary in order to obtain articles or dishes from the back of the shelves to either remove the contents from the front of the particular shelf containing the desired article while the refri erator door is open, and after obtaining the esired article or dish to replace the others, thereby .---all;owing the cold air to escape and be relib placed by hot air, or to reach-over the contents to obtain the desired article or dish, an unsanitary,-awkward and inconvenient method accompanied by the danger of frequently upsetting the various dishes, etc. in the way. Whereas, by my improvement a given shelf is simply whirled around until the desired article on said shelf is at the front of the refrigerator where it can be removed without molesting or interfering with the other articles therein.

211d. To render the refrigerator more adaptable to the various sizes and dimensions of the food dishes and provision articles desiredto be preserved therein by providing shelves which are readily adjusted at any desired depth or height, and which may be used in sections or half sections.

3rd. To create a circulation ofair by providing a communicating pipe between the food chamber and the ice chamber which attracts the hot air from the food chamber, and another communicating pipe from the ice chamber to the food chamber which attracts the cold air from the ice chamber.

ll attain these objects by the mechanismillustra-ted by in which Figure 1 is a vertical section of the interior of the refrigerator showing both the ice chamber and the food chamber with the ventilating pipes and the shelves in place.

2. A ridge V the accompanying drawings Fig. 2 is a erspective view of a single shelf showing its component parts and construction.

Fig. 3 is a cross section-showing one of the shelves in place, in a refrigerator.

Fig. .4 shows how a shelf is secured and fastened to the main shaft or post around which it revolves.

In the drawings A represents the cork lining 'of the refrigerator, B the metal linings which contain the cork, C the wooden exterior of the refrigerator, l) the drain pipe from the ice chamber W, the longer and shorter ventilatin pipes, respectively between the ice cham r W and the food chamber Y.

The shaft or post K to which the shelves L are fastened and around which they revolve contains horizontal holes M drilled through the shaft at frequent intervals. The metal strip N which carries a given shelf L (Fig. 2) is reinforced at the center around the hole through which the post or shaft K, centrally positioned between the shelf Z and the bottom of the refrigerator passes by a piece of iron or steel P having a hollow pipe-shaped casing Q extending downward at least two inches in length, just large enough for the shaft or post K to pass through. 7 This secures the shelves L against any tendency of rocking or tipping but permits the shelves to freely revolve about the post K. lltjis manifest that .the vertical distance in which the shaft or post K is incased in the shelf carrying strip N and its reinforcing piece P lower end of which the supporting pin R is placed through the adjacent hole M necessarily eliminates any rocking of the shelves. (Fig. 4:).

The shelves L themselves are made in half sections. The under side of each half section contains two metal parts or cleats designated as H, the ends of each protruding and bending downward. These protruding ends slip into corresponding notches U on the flat iron strip N, as illustrated by Fig. is turned up slightly at the edge of the shelf so as to prevent articles from falling over-the sides.

The ventilating system illustrated by Fig. 1 shows on the right hand side a hollow pipe designated by the letter E, which extends from the top of the food chamber to a point near the top of the ice chamber. On the left and E and l?- Patented Jan. 14,1919.

hand side designated by the letter F, isa similar pipe which extends from a lower point in the ice chamber, than that to which pipe E extends, to the top of the food cham- 1. Pipe E, extendingto a higher point in the ice chamber than pipe F, both communicating with the 'food chamber, causes the warmer air inthe food chamber to gravis tate toward and ascend in pipe E, the cold air which it displaces in the ice chamber to ing a lower food chamber and an upper ice chamber, of a vertical post secured centrally within the food chamber and having a plurality of spaced horizontally. disposed, openings, pins for said-openings, a horizontally mu es disposed metal strip having s aced pairs of notchesjin its opposite side e ges, a hollow casing secured centrally to and dependi from the underside of the said strip, sai casing and strip slidably mounted on said post and supported in adjusted position thereon by sald ins, a air of semi-circular shelvesfitted. a out said 0st and resting upon the upper side of sai strip, and pairs 0 spaced cleats secured to each semi-circular shelf and fitting in the notches of said strip whereby said shelf-sections are held against displacement withrelation to the post and the engagement of the shelves with the upper side of the strip prevents tilting thereof.
