TTTTTTTT 0R mmm! I m 17 r Patented Oct. 29, 1935 UNITED STATES VENTILATOR Francois Olivier Bissonnette, Montreal, Quebec, Canada Application August 28, 1933, Serial No. 687,034 In Canada September 30, 1932 1 Claim.

The present invention pertains to a novel ventilator designed particularly for use in kitchens, although it is also adapted for use in other rooms where there is a flue outlet regardless of whether a stove is used in said room.

The principal object of said invention is to provide a device which adapts the built-in flue passage leading to the chimney for ventilating purposes. In the accomplishment of this object, the flue opening in the wall is fitted with a face plate adapted to receive the flue pipe leading from the stove. The face plate has, in addition, a ventilating opening equipped with a suitable adjustable cover plate which may be positioned according to the desired amount of ventilation. Ventilation is induced by the natural draught in the built-in flue passage within the wall.

It is also within the scope of the invention to provide such an installation having a ventilating opening but no flue opening; or the flue opening previously described may be covered. Such a device is adapted for use in a. room having a flue opening in the wall but not containing a stove.

The invention is fully disclosed by way of example in the following description and in the accompanying drawing, in which:

Figure l is an elevation of a device according to the invention;

Figure 2 is a vertical section thereof;

Figure 3 is a front elevation of a modified construction showing the flue pipe in section;

Figure 4 is a vertical section corresponding to Figure 3, showing the pipe in elevation;

Figure 5 is an elevation of the same construction of the ventilator adapted for a larger flue pipe which is shown in section;

Figure 6 is an elevation of the form shown in Figure 1, with the flue opening covered; and

Figure 7 is an elevation of a modification having no flue opening.

Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.

In Figure 2 is illustrated one of the walls of a building I in which is built a ventilating flue 2 which communicates with a chimney on the roof in the usual manner. An opening 3 in the wall extends from the flue into communication with the room and in the present instance is larger than the conventional opening for a flue pipe, for a purpose which will presently appear. Into this opening is inserted a collar 4 covered by a face plate 5 as shown more clearly in Figure 1.

A flange or collar 6 is formed in the face plate and is of such size as to receive the upper end of a conventional flue pipe 1 leading from a stove or gas range. Adjacent to the collar 6 the face plate 5 is formed with an opening 8 of substantial size and preferably of semi-circular config- 5 uration. A similarly shaped plate 9 adapted to cover the opening has one end pivoted to the face plate as indicated by the numeral I0. Stops II secured to the face plate 5 at the lower edge of the opening 8 are adapted to hold the cover 10 plate 9 in its lowered or closed position.

When the plate 9 uncovers the opening 8 as shown in Figure 1, a ventilating effect at the opening is produced by reason of thedraught in the flue 2. Cables I2 and I3 are attached to 15 a lug I4 on the cover plate and extend in opposite directions therefrom. These cables are suitably suspended at I5 and equipped with handles I6, so that they may be pulled selectively to open and close the opening 8 in accordance with the amount of ventilation desired.

In the modification shown in Figures 3, 4 and 5 the cover plate 20 has its ends mounted in bearings 2| so that it may be pulled outwardly from the face plate 22 by means of the cable 23. 25 A spring 24 extends from a lug 25 on the cover plate to a suitable fixed point and tends to draw the cover plate into closed position with respect to the ventilating opening 26. The cable may be held in lowered position by any suitable means, 30 and when it is released, the spring 24 brings the plate 20 to closed position.

Figure 5 shows the same construction except that the lower portion of the face plate 22 is adapted to receive the end of a flue pipe 21 of 35 larger than usual cross section and substantially semi-circular.

The modification shown in Figure 6 is similar to the construction of Figures 1 and 2 except that the flue opening of the latter is permanently closed by a plate 28. This device therefore is adapted only for room ventilation and may be installed for this purpose where the usual flue opening to the chimney is not in connection with a stove.

The device shown in Figure 7 is provided for the same purpose. In this case, however, the upper portion of the face plate 30 is provided with a series of apertures 3| rather than a sin- 50 gle large opening, to diffuse the air stream. A semi-circular cover plate 32 is hinged to the face plate at 33 so that it is adapted to cover and uncover the openings 3|. The stop 34 holds the cover plate in its lowermost position, and cables 3 35 are attached to the plate for adjusting the position thereof.

Although specific embodiments of the invention have been illustrated and described, it will be understood that various alterations in the details of construction may be made without departing from the scope of the invention as indicated by the appended claim.

What I claim is: I A ventilator comprising a collar adapted to be mounted in the flue opening in a wall, a face plate mounted on the outer end of said collar said plate having an opening therethrough, a cover plate hingedly mounted over said opening and adapted to cover and uncover the latter, said face plate having another opening, and a flanged member fitted in the latter opening and adapted to receive a flue pipe.
