4 Claims.

My invention relates to ventilators and more particularly to a stationary type of ventilator for use in buildings or the like.

An object f my invention is to provide a device that may be permanently installed in the outer wall of a building or enclosure and arranged in a manner to exclude the elements, and lter or screen the air as it enters or leaves the enclosure.

Another object of my invention is to provide a device that may be easily assembled and installed without the use of special tools.

Another object of my invention is to provide a device that is arranged to lock into a fixed position when assembled.

A still further object of my invention is to provide a device that is easily constructed, economical to manufacture, efcient and practical for the purpose for which it is intended.

It is manifest to anyone familiar with the use of permanently installed ventilators that they are quite frequently the cause of snow, rain, insects or the like entering the enclosure. With the device described, illustrated and claimed, these objectionable features are entirely eliminated. The device is simple in constructtion, may be easily installed and made accessible for cleaning purposes.

Other and further objects of my invention will become more apparent as the description proceeds and when taken in conjunction with the drawings in which Figure l is a perspective view of the entire assembled device.

Figure 2 is a perspective view of the angularly disposed housing forming a screening portion for the device.

Figure 3 is a composite perspective rear view of the component parts constituting the device.

Figure 4 is a vertical cross-sectional view of the assembled device, and

Figure 5 is a horizontal cross-sectional view of the device taken at the line 5-5 in Figure 4.

Similar characters of reference indicate corresponding parts throughout the several views, and referring now to the same, the character I0 shows a face plate for engagement with the outer surface of a wall having an aperture through its center and having inwardly disposed members I I, I I and I l, thereby forming a frame for the support of a plurality of louvres or angularly disposed horizontal blades I2. These louvre blades may be mounted in a Xed position, or may be pivotally mounted for adjustment. The lower frame section II. is shown angularly dis- 2 i j posed to conform with the angle of the louvre blades I2.

The side frame members I I, are equipped with inwardly extending flange members I3 and the lower frame member I I is provided with an inwardly extending ange member I3. The face plate I0 is shown as having a plurality of apertures I4 therein, in which screws are inserted for attaching the plate I0 to the outer surface of a wall or the like, and when the plate I0 is placed in a fixed position, the frame formed by the walls Il, II and II extend inward for receiving an angularly disposed housing shown as I5, which has outwardly projecting members IB on the sides and bottom for engagement with the flange members I3 and I3 of the frame, and inwardly extending channel members I1 at the top for the slidable support of a screen or filtering member I8 in the form of a removable frame equipped with wire screen or the like.

The upper portion II of the frame structure supports a retaining member I9 arranged to retain the forward end of the filtering frame member I8 when the device is in an assembled position as shown in Figures l and 4.

Obviously, the front frame I0 is attached from the outside by means of screws through the apertures I4, and the entire frame structure consisting of a wall I I, I I and Il extends inward, permitting the housing I5 to be slidably brought into position and held by means of the inwardly extending flange members I3 and the outwardly projecting members I 6, after the frame IB has been slidably inserted into the channel I1, at which time the retaining member I9, which is in a Vertical position as shown in Figure 3, is brought down into a horizontal position as shown in Figure 4, thereby locking the housing I5 into position. To remove the housing I5 with the ltering frame I0 in position, it is only necessary to bend the member I9 upward and raise the entire housing I5 out of engagement with the frame members.

In the chosen embodiments of my invention, there are many features not heretofore disclosed in the prior art, and although I have shown a speciiic construction, I am fully cognizant of the fact that many changes in the form and coniiguration of the engaging channels and flanges as well as the shape and contour of the entire device may be made, without affecting its operativeness, and I reserve the right to make such changes as I may deem convenient or necessary without departing from the spirit of my invention or the scope of the appended claims.

member inclined upwardly relative tol the face plate, means for engaging said housing at its forward end with said frame, a ltering means, and channel members formed at the top of the vertical side Walls for the slidable engagement of said ltering means.

2. A device of the character described cornprising in combination a face plate provided with a central opening therein, said face plate being vertically disposed, flanges projecting outward from the opening in said face plate forming a frame, a plurality of louvres angularly disposed within said frame, a housing, said housing provided with an open forward end and having two vertical side walls and a bottom member inclined upwardly relative to the face plate, means for engaging said housing at its forward open end with said frame, a filtering member and horizontal channel members formed on the top of vertical side walls of said housing for slidably engaging said ltering means.

3. A device of the character described comprising a face plate having a central opening therein, said face plate vertically disposed, flanges forming a frame projecting from the inner edges of the opening in said face plate and forming a Ipart thereof, a plurality of louvres angularly disposed Within said frame, a housing, said housing having its bottom upwardly inclined relative to the face plate and open at its forward end, a pair of vertical side walls, means in the form of anges on said housing for slidably engaging said housing at its forward end with said frame, a filtering means and horizontal channels on the upper edges of said vertical side walls for the slidable engagement of said filtering means.

4. A device of the character described comprising a vertical face plate having a central aperture, flanges projecting outward from said Yface plate, said frame consisting of a top portion, a bottom portion and two side portions, said bottom portion angularly disposed, said side and bottom frame portions provided with anges extending inward, a plurality of louvres disposed within said framefsaid louvres supported by the inside of said frame and mounted thereto, a housing, said housing having vertical side walls and being upwardly inclined at the bottom, anges on the side and bottom walls of said housing for slidable engagement with the anges on said frame, a ltering means, said housing having the top of its vertical side walls provided with horizontal channels for slidably supporting said filtering means.
