well known to the merchantsand public. Attempts have been made to eliminate and avoid 10 such moisture condensation, as by creating a forced circulation of air over the window with an electric fan, but this ractice is notalways convenient or feasible. he present invention aims to provide a simple apparatus for removlg ing excesslve moisture from the an; and for creating a circulation of air as well as for cooling the air at the inner side of the window.

Broadly my invention resides in the removal of moisture from the air at the inner 2 side of the show window, or other surfaces designed to be freed from having the moisture in the air condensed thereon. The referred embodiment of my invention resi es in arranging a cooling element so that the air at the inside of the window will be caused to come in contact therewith andwthe moisture in the air will condense upon the cooling element and thereby render the air free from excessive moisture.

While the-air may circulate through a system which embodies the cooling element, a simple form of the invention is illustrated in the accompanying drawin s in which thecooling element is disposed adj acent the window,

- preferably in a-position concealed from an exterior view through" the window or so arranged as not to detract from the appearance of the window, for the purpose of cooling the air to a temperature more nearly approximating the outdoor temperature.

In its preferred embodiment the invention contemplates the arrangement of the cooling unit ad acent the top of the window and connected to a refrigerating mechanism arranged in a compartment or room separate from the show window, as in the basement of the store. Underl ing the cooling member are arranged means or removing such waters of condensation as may have become deposited thereon in the form of an icy'coating and which will thaw during the periods of rest on the the coolin unit.

Inthe rawings,

Fig. 1 is 'a more or less diagrammatic view 111 perspective illustrating the condensation preventmg apparatus installed at the inner side of a show window.

Fig. 2 is a detailed cross sectional view depicting more clearly the cooling member and its associated trough.

Referring more in detail'to the accompanying drawings, the numeral 1 designates the show windowof a store adjacent the inner part of side of. which is disposed the tubular or cylindrical cooling element 2 of the apparatus. This cooling element is depicted as being an portion of the window so t at as the alris cooled thereby such cooled air will tend to fall or descend across the inner face of the window 1 and tend to create a circulation in which the cooler air has initial contact with the window. The arrangement of this cooling element'adjacent the top of the window permits the same to be more readily concealed to view from the exterior of the window by the usual window drapes and trim-' mings. Since the cooling member 2 is colder than the inner face of the glass .of the window the moisture in the .store air. will condense upon said colder member and gradually form an icy coating therefor. In View of the fact that the modern show windows have their display space partitioned from the remainder of the store by paneled walls, the air within the show window is more or less confined so that the action of the cooling'memberwill be to remove excess moisture from this confined air and render itcomparatively dry. Under this condition of the air the coolin member ma be discontinued in its operation for a brie period, or until the air has been sufficiently mingled with moisture-ladened'air as to necessitate its functionmg in order to prevent the moisture from condensing upon the glass. When the cooling member is inoperative thei'cy deposit thereelongated body arranged ad'acent the upper v densation will drain as through pipe 4 to a suitable escape.

The cooling member 2 is connected by pipes 5 and 6 in circuit with an expansion tank 7 forming part of a refrigerating apparatus embodying a compressor 8 and its operating motor 9. The major portion of the apparatus, including the motor, compressor and expansion tank, is preferably dis osed. in a concealed position, such as in the asement of the store, as diagrammatically illustrated in Figure 1.

The apparatus-thus described will effectively prevent the condensation of water vapors upon the interior of the window by cooling the air adjacent the inner face of the window to a temperature approaching or even colder than the outdoor temperature. In

.addition to this a considerable portion of 1. Condensation preventing apparatus for show windows, comprising in combination means for rendering the cooling element operative for the condensation and precipitation of water vapors of the air ad acent thereto, and a trough underlying the element trough.

6. The method of preventing condensation on show windows, or the like, cofgsisting in cooling the air ad] acent the top o a window thereby causing a downfiowing current of air to pass over the window and simultaneously condensing and precipitating the vapors in the air. I

7. In combination with a show window, a cooling member 'of a refrigerating apparatus mounted adjacent thereto, for creating a circulation of the air at the inner side of the .window and simultaneously acting to remove excessive moisture from the air whereby the air is rendered partiljjv dry. v RWIN C. HORTON.
