VENTILATOR HAT FOR STOVES Filed April 17, 1930 H. MTKH.

Patented Sept. 29, 1931 UNITED STATES ALBERT NITKA, OF MILWAUKEE, WISCONSIN VENTILATOR HAT FOR STOVES Application filed April 17,

My invention refers to ventilators and is particularly designed for use in connection with cook stoves, or the like.

The object of this invention is to provide in connection with a stove hood ventilator, a motor driven fan whereby a current of air is drawn up through the hood and discharged to the atmosphere.

With the above object in view, the invention consists in certain pecularities of construction and combination of parts as will be fully set forth with reference to the accompanying drawings.

In the drawings, Figure 1 represents a front elevation of a stove and ventilator hood embodying the features of my invention; and

Figure 2 is a side elevation of the same with parts broken away and other parts in section to more clearly illustrate structural features.

Referring by characters to the drawings, 1 represents a standard stove, and mounted thereover is a hood 2 having conical faces upon four sides which merge into an opening 3 at the top for the reception of a ventilator pipe 4, which pipe may enter a convenient chimney or it may be directed through a window, or other accessible opening to the atmosphere.

The lower flanged lip 5 of the hood is, as shown, anchored to the wall by a clip 6 and the hood at its mouth end is of suflicient dimenslon to encompass the full area of the stove, whereby smoke and odors therefrom will be cleared and discharged through the ventilator pipe.

In order to create a forced draft which is sufficient at all times to draw into the hood the entire volume of smoke and odors, I provide brackets 7, which brackets extend from the inner walls of the hood near its upper end, and resting thereupon and secured to the brackets is an electric motor 8, having ears extending therefrom for engagement with the bracket.

The motor shaft 9 is in axial alignment with the mouth of the ventilator pipe and extends in parallel relation to the pipe mouth.

The end of the shaft 9 has secured thereto 1930. Serial No. 445,066.

a propellor or suction fan 10, which fan is approximately the diameter of the vent pipe and is housed directly beyond its mouth, as shown in Figure 2 of the drawings.

By this arrangement, it will be observed that the hood for ventilating a cook stove and kitchen, is rendered capable of disposing of all of the odors and gases which may arise from the stove irrespective of draft conditions of the pipe 4, and all that is necessary to put the apparatus into operation is to close a switch which will control the electric current to the motor, the said wiring and switch forming no part of my invention and not shown. It will be noted that the hood may be made up in portable form as, for example, it might constitute a part of, or be attached to the stove, in which case, the pipewould be thereafter assembled and connected to any suitable vent opening.

Inasmuch as in practice, the hood 2 must necessarily be positioned in spaced relation above the stove in order to permit suitable access thereto, it may be desirable in some instances to provide a shield 11, which may be attached to the stove in any suitable manner and project upwardly into close proximity to the mouth of the hood.

It will also be obvious that the sides of the shield will prevent side drafts from carrying odors away from the stove, and will insure the same being drawn into the hood.

Due to the fact that vapors and odors are discharged through the vent pipe 4L with considerable force, it has been found that were the same delivered into a flue at an approximate right angle to the flue, considerable back pressure is built up, which interferes materially with the draft of the flue and any other heating apparatus connected therewith.

It is, therefore, proposed to connect the ventilating pipe 4 with an angularly disposed communication 4 with the interior of the flue. Thus, as the vapors are discharged into the flue, the same will be directed upwardly, whereby the draft within the flue will be increased rather than retarded.

While I have shown and described the preferred embodiment of my invention, it will be apparent that slight changes may be made in the construction when putting the invention into practice Without departing from the spirit of the same or the scope of the appended claim.

I claim:

A ventilator hood for stoves having a mouth adapted to be positioned over the top or" the stove and having an opening in its top Wall, a vent pipe leading from said opening, brackets extending from the inner Wall of the hood, a motor carried by the brackets, a fan associated with the motor and extending into the Vent pipe and a shield depending from the lower open side of the hood and embracing the back and sides of the stove.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.

ALBERT NITKA.
