SPECIFICATION forming part of Letters Patent No.299,432, dated May 27, 1884; .Application filed December 18, 1883. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM D. SMITH, a

citizen of the United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in \Vindows; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked which form a part of this specification.

My invention relates to improvements'in box or show windows; and it consists in the construction, combination, and arrangement of the several parts, as will be hereinafter more fully described and claimed.

In the drawings, Figure 1 is a perspective View of my window. Fig. 2 is a vertical section thereof. Fig. 3 is a cross-section on line as m, Fig. 1. Fig. 4 is a rear elevationof the window.

The front of the window glass plates A, and a door, A, is hung at its rear side, as shown. The sides are shown without glass, but may be so supplied when desired. The bottom B of the window is provided near its forward edge with an opening, B, covered by a wire or other suitable netting or grating, B A valve, 0, is held in suitable guides close against the opening B, and may be adjusted forward or back, to vary size of opening B or entirely close same, as will be understood. In the front of the win dow, below the bottom B and in line with opening B, I form an opening, D, covered by grating D. An air-inlet passage or flue is formed between the openings D B by the in clined deflector E and the sides E. By this construction it will be seen the air can pass freely into the window, yet all dirt particles are excluded by the gratings, of which I-preferably use two, D and B and make of fine net-work. At the upper rear side of the window I form an offset, F, communicating with the window through an opening, F, covered by wire-netting F*. This offset extends the full width of the window, and is provided at one end with a pipe, G, which extends lateris provided with ally from the window, and in use is projected into a chimney. Pipes H H extend vertically up from the top of the window, and in practice extend into fines or chimneys, to attain which end they may be bent and made of any suitable length desired.

I have not thought it necessary to illustrate fines or chimneys, as it will be obvious to persons skilled in building at what points and how it will be best to open the pipes H H G thereinto.

\Vhere so desired, pipes G may be extended from both ends of the offset, and it will be appreciated that where either pipes G or H are used alone in connection with the lower opening, B, good results will be had; but I prefer to use both pipes G and H, as before described.

I also prefer the form of lower air-inlet described and shown, as thereby the air is received directly from the open air, and is so delivered into the window, and in its passage all dirt, &c. is stopped, and does not enter the window.

By use of the pipes O H extended and opening into the dues or chimneys, it will be seen that I get a draft of air upward through the window from its lower. end, and that a constant upward circulation of fresh air of equal temperature is had. This prevents all sweating of the window common to ordinary showwindows. The upward draft, it will be understood, causes a constant circulation, and the air in the perature. Were the upper opening made directly out into the air, as is the lower one, it will be appreciated that this constant circulation would not be had, but that the air would flow into the window from both openings. By my improvement I gain a constant even circulation, and consequently better results, as will be appreciated.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The window substantially as described and shown, provided in its lower end with an air-inlet, and in its upper end with an air exit or exits communicating with the flues or chimneys, substantially as and for the purposes set forth.

window is kept at an even tem 2. The combination, with a box or show window, substantially as herein described, having an air-inlet in its lower end, of pipes, as G H, extended from its upper end and pro- 5 jccted into ilues or chimneys, substantially as described, and for the purposes set forth.

3. The improved box or show window, substantially as described and shown, having an opening, B, in its bottom, and provided in its front side, below said bottom, with an opening, D, connected by passage E E with opening B, the hinged door A, the offset F at its upper rear side, and pipes G H, all arranged and operating substantially as and for the pur- I 5 poses set forth.
