WINDOW-VENTILATOR.

EPLECIFICATION forming part of Letters Patent No. 331,796, dated December 8, 1885.

Application filed April 20, 1883. Serial No. 92,370. (130 model.)

To all whom, it may concern:

Be it known that I, PHILIPP (J. Knarrnn, of Louisville, in the county of Jefferson and State of Kentucky, have invented a new and useful Improvementin Show-Window and Cellar Ventilators,which improvement; is fully set forth in the following specification and accompanying drawings, in which- Figure 1 isa cross vertical section of a show window equipped with my improved ventilating device. Fig. 2 is a perspective of my improved Window.

The present invention relates to show-win dow and cellar ventilators for stores; and the object is to provide a system of ventilation or drafts for the show-window and the cellar, so that the show-window will not receive or deposit moisture in cold weather and obstruct the View from the outside, and to enable the cellar beneath the store-floor to be ventilated during the summer months, all of which will now be set forth in detail. I

In the accompanying drawings, A represents the store-floor, and B the show-window floor or platform. 0 is the cellar-space below the show-window. D represents an open ing through the floor along the forward end or side of the show-window, which opening is designed to communicate directly with the cellar O. In case the show-window extends over the line of the cellar, as is the case in some instances, I design having fines communicating with the opening D and extending back under the floor A to the cellar. The front or both front and sides of the showwindow are provided with an opening or openings, E, having in said openings screens F. These openings are located in the sides of the show window frame below the floor B. The space below the floor B is divided into two compartments by means of a partition, G. The front compartment, H, is in communication with the openings D E, which extend practically the entire width of the glass, and the rear compartment, I, is in communication with the opening J, having a suitable door, K. The rear compartment, I, may be used for a storage-room, and the partition G is designed to prevent air from the openings D E passing into the store through the opening J when the door K is opened. The show-window floor B has near its outer end an opening, L, communicating with the chamber H. The upper end of the show-window has in the outer face,or in both the sides and the ends of the frame, openings M, provided with screens N. These openings have glass transonis or doors 0, hinged on the inside. P represents a cord attached to the transom, and running thence over pulleys Q to the inner side of the show-window, so that the said transom 0 may be opened by a person inside the store by the depending cord P.

R represents the show-window glass, and S the door communicating with the interior of the store.

The operation of the invention is simple and readily understood.

On thefloor A is a slide or registeigU, which projects forward so that it covers the opening D in the floor. The under side of the floorB is similarly provided with a rogiste1,V, which closes the opening L.

In cold weather the transom O is opened, as shown by dotted lines, and the upper register,V, drawn back, as shown in the drawings. The lower register, U, is pushed forward so as to cover the opening D. The cold air from the outside therefore enters the opening E, passes through the opening L, ascends to the transom-opening M, and passes out, thereby cooling the interior of the showwindow,causing the air from the outside to enter feeely and circulate, so as to bring the temperature the same within that it is without, and thus prevent condensation from taking place on the glass.

In warm weather the register V and transom O are closed and the register U opened, so that the cellar can be ventilated and the gases and noxious vapors passed out through the openings D E.

Having described my inventiomwhat I claim A show or bulk window of the character described, having ventilating-openings at top and bottom extending substantially the en tire width of theglass, a floor above the lower openings, said floor provided with corresponding openings near the walls of the window, all

have hereunto set my hand, this 26th day of February, 1883, in the presence of witnesses.

the said openings provided with valves by which they may be opened or closed, and an opening between the cellarand theiower openings in the window, and means for closing 5 said opening at wilhsubstantially as described,
