H. F. TBDEMAN VENTILATOR Filed June 30, 1945 Patented Dec. 14, 1948 l UNITED. sTATas PATl-:N

TOPFICE- The present invention relates to Ventilating fans and is particularly directed to the provision of a device of this character wherein the fan may be disposed in a window or other opening in such a way that when the fan is in useit lies in the proper position to direct air through the opening and when the fan is not in use, it is moved into an inoperative position and carries with it a closure for the opening. L

My invention contemplates the provision of a supporting device consisting of what I may call two plate sections angularly disposed with respect to each other and meeting substantially on a hinge line where a hinge is provided to mount the device in such opening. Either plate section may be locked to the casing of the opening and the other plate section will thereuponstand out from the opening toward the outside or the 1nside as the case may be. The preferredangle between the plate sections is such as to prevent substantial interference with the air ystream from the ian. The fan is mounted in one plate section and maf; comprise a simple framework that is mounted by a hinge at the opening. .The other plate section may be either transparent or opaque, and may be cut down to t diiierent sizes of openings.

The nature and advantages ofmy invention will appear more. fully from the following description and the accompanying drawing wherein a preferred form of the invention-is shown. `It should be understood however that the drawi and description are illustrative only and should not be taken as limiting the invention except insoar as it is limited by the claims.

In the drawing:

Figure 1 is a vertical sectional view through l window to which my device has been applied;

Figure 2 is a perspective view of a completed mit whichv is adapted to be inserted in the place f a section of the glass in the window;-

Figure 3 is a view similar to Figure 2 but with he parts in their alternative position; and

Figure 4 is an enlarged sectional view taken 'ertically through the device substantially on line -ii of Figure 2.

Referring now in detail to the drawings, the Iresent invention is adapted to be applied to an pening, such as a Window 5, the upper section of which is provided with several panes of lass, such as that shown at 'I in Figure 1. )wer section 8 of the window mayhave one or lore panes of glass.

1y invention may be applied thereto. However,

(Cl. 98- 94) 2 l it is obvious the invention is not limited'to'any v f particular type of window. or opening, the device merely as .a closure for 'a certain` itself being complete and adapted to be mounted in any opening.

The device comprises a main framed which may be of any desirable width and which may befconstructed of any suitable material, preferably a transparent sheet material. that can be cut down to 2 and 4 show dotted portions 9a and 9b that can be cut o to bring the frame 9 down to the size shown in full lines. material is the transparent resin product sold under the trade .name of=Lucite. The frame upper inner edge, this' 9 has a hinge i'along its hinge preferably being of the continuous or piano type. AThe hinge supports two plate sections II and I2 which are angularly disposed with respect to eachother and which may be integral or xed to each other 'in any suitable fashion so as to stand at a desired' angle with respect to each other. IV find thatthe Y my purpose is one in the neighborhood of 60 de-l grees, as this allows the fan to operate at a relatively high efliciency without making it necessary for the fan to stick out into the room against drapes or shades to an objectionable degree. The frame 9 preferably carries a latch pin I3 which is adapted to engage both sides of the edge of either section II or I2 to lock the same in xed position. v

A fan It is mounted by means of aspider framework I5 man aperture 'It provided inthe plate section Ii. In addition to the spider I also provide the fan with a guard I'I consisting of a number of bars or wires curved as shown in front ofthe blades of the fan Id. `The fan is driven by a motor I8 which is supported in the spider I5 and which may be energized in the usual man- .ner by connecting a cord leading'therefrom to a current outlet within the room.

`It is believed that the operations of the device will be readily understood. If it is desired to Yhave the fan in operation to drive air from a room, the parts are arranged 4as shown in Figure 2 and the fan. is energized. If the fan is to drive air into the room, then the fan parts would be re,- versed on the plate section II.

In fact, the plate section l I may also be of a transparent material that will admit light. The frame 9 preferably is made of a material that is easily cut to size thus making it unnecessary to have different sizes of fan units for different sizes of openings.

Having thus described my invention, I claim:

1- A Ventilating Ian adapted to replace a window pane in a window comprising a supporting framework having an aperture therein, a ian carrying `framework movable into. and out of frame, and a closure for the aperture in said frame iixed to the fancarrying therewith, said closure and fan carrying framework being so positioned with respect to each other that when one is in the aperture in the frame the other one projects laterally from the frame.

2. A Ventilating unit comprising a mounting frame adapted to be inserted in an opening. a pair of plate sections angularly disposed with respect to each other. and joined at their upper edges, hinge means at the junction of said plate sections for mounting them in said frame, and
