Oct. 3, 1950 G. J. MARTIN ADJUSTABLE SCREEN VENTILATOR FOR WINDOWS Filed Jan. 29, 1948 INVENTOR. Gua J. MAR'MN JV'H/YV Patented Oct. 3 1950 ADJUSTABLE SCEEN VEN TILATOR FOR WINDOWS Gus J. Martin, New York, N. Y.

` Application January 29, 194s, serial No. 5,039

(ci. :as-94) 8 Claims.

This invention relates to an adjustable screen ventilator for windows.

An object of the invention is to provide a ventilator device which will tend to air condition rooms in a home, the air entering the room only through the opening in the device.

A further object is to provide a device, or ventilator, as aforesaid, which is adjustable to flt various size Windows and which can be substantially sealed inthe window. Another object is to provide a ventilator as aforesaid having means for filteringthe entering air. l

A further object is to provide a ventilator as aforesaid having improved connections between the main part and the adjustable wings.

` Still further, the present invention proposes the prvision of ventilator which is entirely sealed within the window opening, and which functions to admit a controlled `quantity of air through a specifically provided opening in the center of the main section.`

Another object of the present invention is to construct a ventilator which may be effectively used under all types of weather conditions and which may be used to force air into the room for ventilation purposes, or which may be reversed in its action to discharge stale air from the room.

A still further object of the present invention is to provide a devicehaving a motor operated fan for moving the air, which has `all of its operating parts-enclosed with a suitable housing so as to protect the same against the ruinous` effects of inclement Weather.

A further object of the present invention proposes an inlet opening to the motor housing provided on three sides with a suitable track system the ventilator.

for receiving a filter designed vto remove all dust l Fig. 8 is a rear view of the motor housing looking in the direction of the line 8 8 on Fig.. 6.

Fig. 9 is an enlarged section on the lins 9 9 of Fig. l. i

Fig. 10 is an enlarged detail of a portion of Fig. 1 through which section line 9 9 is taken. Fig. 11 is a View, similar to Fig. l0, of that portion, with the hole therein fully exposed. It is the purpose of the present invention to provide a ventilator which will air condition rooms in the home of a human being. The air will enter the room desired only through the opening in the ventilator, and this air is suitably filtered before it comes in contact with the fa'n" of the ventilator so that it is in purer form than if it had been breathed directly from the atmos-4 phere. The ventilator is adjustable to fit in any of a series of sizes of windows and can be completely edged with foam rubber strips to assure a substantially air-tight nt in the window.

Since the ventilator is tightly held in thewindow opening and since it is completely edged with foam rubber stripping, it will provide a closure which is air tight except for air entrance for air conditioning through the authorized port of the Ventilator. The ventilator can be used to provide ingress of cool fresh air from the outside into the room, or it can be reversed to provide egress of air from the rcom to the outside for clearing the room of stale air.

The ventilator includes a box-like compartment for the fan and motor, the compartment being `provided with a filter so that the air entering the room can be cleansed. The filter is removable so that if the ventilator is reversed, the filter Will not become contaminated by the removal of dirty air fromthe room. i

The part of the ventilator which is normally l displayed to the eye of the occupants of the room ence will be hadto the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention fare'more' particularly set forth.

In the accompanying drawings forming a materialpart of this disclosure:

Fig. 1 is a front View of a ventilator constructed in accordance with this invention, in position in a window.

Fig. 2 is a plan of the ventilator of Fig. 1.

Fig. 3 `is a plan of the main part of the ventilator ofFig. l, the side Wings being eliminated.

Fig. 41s an enlarged vertical section taken on the line 4 5 of Fig. l.

Fig. 5 is an enlarged section on the line 5 5 of Fig. 1. l

is neat and attractive in appearance. The ventilator has a main female part and lateral adjustable male wings. The top and bottom ars symmetrical, the only difference being that there is an opening in the front face near the bottom for an electric cord.

The ventilator I 0, constructed in accordance with the present invention, can be utilized with The of the window frame` l2 and the bottom sash I 3 is forced down on top of the ventilator. ventilator in any of its adjusted sizes is rectangm lar and when it is placed in the window, it is first l The ventilator` has a main female part `l 5. This The l part is formed partly of a long rectangular piece of sheet metal provided at its center with a 01rcular hole i6 forming part of the air duct. It is bent at its top and b-ottom, at right angles, to

form a top wall Il and a bottom wall i8, the remainder of the sheet forming a front wall I9, in which the hole I6 is located. A member is fastened, as by screws 2lia or the like, to each of the top and bottom walls. Each member consists of portion 2i) superposed on wall lll or It, as the case may be, a rear iiange 2l, a front flange 22 and superposed on wall i9, and a channel 23 integral with front flange 22. The two channels 23 are oppositely disposed, the top one opening upwardly and the bottom one opening downwardly. At its ends, each flange 2l is cut to form tabs 2l=L which are bent under and fastened to the'bottom of wall Il or i3'. Each wall 20 has a slot 24 extending from each of its opposite ends toward, but not to, the middle of the Ventilator, see Fig. 3.

The ventilator has two male wings 25. The wings are identical and one is shown in Fig. '7. It has a front wall 2t and top, bottom and outer end walls 2l, 28 and 2S respectively. The front wall has a vertical slit 3@ and is cut through its edge opposite wall 29 from slit Se to provide top and bottom tongues 3l. In its assemblage with the female portion, the walls 2'! and 28 fit into the top and bottom slots 2li respectively and the tongues 3| slide in the channels 23. Thus, the overall length of the ventilator may be adjusted by sliding the male wings 25 relative to the female part l5. The male wings are designed for easy adjustment of the ventilator to different sized windows.

A box-like compartment 3?. is secured to the inner face of the main. female part i over the hole i6, this compartment being rectangular in cross section and having a flange 33 attached to the wall i9. One end of the compartment is formed on three sides with a track system 311 for receiving a lter 35. The lter 35 slides througha slot 36 formed in one of the side walls of the compartment, and the tracks extend from the compartment 32 at Ithe top and bottom of the slot 36 to facilitate insertion and removal of the ilter 35, which is provided with a knob 35a by which it may be manually gripped. A fan 3l, with an electric motor 38, is supported in the compartment, the electric cord 3S of the motor passing through a hole in the bottom of the compartment. The hole i6, in the wall i9, is covered by a wire screen 40 for safety precautions.

The fan is directed to blow cold or fresh air from the atmosphere into the room, the air passing through the iilter to the ian and being forced through the screen il@ into the room. If it is desired to blow or draw the air out of the room, the entire ventilator can be reversed, placing the compartment in the room and removing the lter, or the motor can be reversed, if it is a reversible motor, the filter rst being removed. The filter is made of several layers of iine wire screen` The foam rubber substantially seals the venti'- later except for the hole l5, whereby all the air entering the room must be ltered. The electric cord 39 must enter the room for connection with the usual wall socket, not shown, and a rectangular hole 4l is provided in the wall lil' for this purpose, the hole 4l being just large enough for a small male plug t2' to pass through. Since the wire 39 will occupy the hole il it is desired to close this hole as much as possible to lmaintain the air tight condition of the ventilator. To accomplish this, a small frame 43 is fastened to the innerface of wall I9 about the hole 4l and two small sliding doors 44 are positioned in the frame, each door 44 having a semicircular opening 45. These doors are moved apart (Fig. 11) to permit the passing of the plug 42 through the hole 4l, and are moved together (Fig. l0) to leave a hole only the size of the cord 39 so that cord 39 seals the hole and no space for leakage is left. This is important for if the Ventilator is reversed, the plug must be returned through the hole 4| as the compartment will then be in the room, and if the plug were not returned, it would be hanging out of the window.

It is to be understood that theopeningsmay be in the form of a deep slotandtheemembers-.M may be of C-shape; One of these members. may be left permanently in position while the other sliding door 44 may be moved to any adjusted position to accommodate the electric wire and plug.

While I have illustratedandV described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modications coming within the scope of the invention as defined in the appended claims.
