VENTILATOR.

Specification of Letters Patent.

Application filed December 5, 1910. Serial No. 595,687.

To all whom it may concern:

Be it known that I, EDMOND GAGNON, a subject of the King of England, residing at Montreal, in the Province of Quebec, Canada, have invented certain new and useful Improvements in Ventilators; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to ventilators and more particularly to ventilators of the fan type.

It is especially designed for domestic use.

In order to more clearly disclose the construction, operation, and use of the invention, reference should be had to the accompanying drawings forming part of the present application.

Throughout the several figures of the drawings like reference characters designate the same parts.

In the drawings: Figure 1 is a vertical cross section through the invention complete, and as applied; Fig. 2 is a bottom plan View of the same; Fig. 3 is a side elevation of the same; Fig. 1 is an enlarged, detail, sectional view of the fan mounting; and Fig. 5 is a diagrammatic view, showing the application of the invention.

The main objects of the invention are to produce a simple, economical, and durable fan ventilator with greatly increased efliciency.

Another object of the invention is to provide a ventilator which may be easily, quickly, and accurately assembled, and equally well separated to permit of repairs, renewals of parts, cleaning, &c.

Referring to the drawings in detail, 1 indicates a stove pipe flue or conduit, in which the ventilator may be placed and through which there is, normally, a considerable draft. This pipe is provided with an opening 2 in one side. About this opening is soldered or otherwise secured a branch pipe 3 across which extends, diametrically, a bar or rod 4c, provided with a small socket or bearing adapted to freely receive the upper reduced end of a small shaft 5 provided with a hub 6 from which extend radially a plurality of fan blades or vanes 7. The lower end of the shaft 5 is reduced or pointed and seated in a socket or cavity formed in a bearing block of glass 8, or a block of other durable material. The bearing block is mounted in the bottom of a cup shaped socket 9 extending from the upper end of a rod 10. The rod 10 is divided into three separate loop shaped arms 11 the outer ends of which are removably clamped to a skirt flange 12 by means of small straps 13 which are drawn into operative position by means of clamping bolts and nuts 14. The skirt flange is formed as an integral part of the branch pipe 3. Thus, the rod or post 10 with its bearing block, may be securely held in operative position to support the fan, and, of course, it may be adjustable vertically to properly seat the ends of the fan post 5 in its bearings.

In order to increase the eifective draft of the fan, each blade is provided with a downwardly and. outwardly bent arm 15 the lower end of which projects slightly below the lower edge of the skirt flange. To each arm 15 is rigidly fixed a plate 16. The plates 16 are mounted tangentially to the circumference of the circle described by the lower ends of arms 15. Consequently, as the arms rotate, the plates 16 will act to draw the surrounding air inwardy toward the center of the circle and beneath the skirt flange. The rotating fan blades 7 then act to draw this air rapidly upward and deliver it through branch pipe 3 and into pipe 1. In this way, a continuous inward and upward draft will be assured. In the preferred form, the transverse rod 4 is in the form of a removable bolt, thus permitting all parts of the ventilator to be readily and quickly removed.

In order to prevent particles of dust and other matter dropping back from the pipe 1 and into the branch 3, a deflector 17 is provided in each of the pipes 1 adjacent each opening 2. This deflector is simply a small plate extending upwardly and rearwardly across the opening 2 in a slightly inclined position, to create an upward current of the air passing through the pipe 1, at these points, thus, carrying all particles of dust or the like upwardly, beyond, and over the openings without dropping therein.

Preferably, a damper 18 is provided in each branch pipe 3 so that they may be individually out off from the pipe 1, whenever desired.

The device is arranged in a branch pipe 2 connected to a flue pipe 1 extending a long, or short distance from, the ceiling, or it may be arranged in a branch pipe extending across the top surface of a stove, preferably with the wide mouth end of the skirt flange extending downwardly to aid in the gathering and directing of the heated air, smoke, noxious gases &c.

The operation is as follows: The heated air with the smoke, noxious gases &c. rises as is well known and a portion thereof enters the skirt flange which guides them to the vanes 7 between which they pass to the flue 1 and through this fine 1 to the atmosphere, or to any point desired. In passing between the fan vanes 7 however the hot air, gases, smoke &c. will rotate the same thereby causing the blades 16 attached to said vanes 7 to rotate therewith. These blades 16 in thus rotating draw all the surrounding hot air, smoke, noxious gases &c. near the ceiling of the room into the skirt flange from which they follow the course above described to the atmosphere. Thus it will be seen that the blades 16 in rotating create a lateral draft thereby expediting the clearance of all smoke, hot air, noxious gases &c. which would otherwise hang suspended at or near the ceiling until they gradually work to and pass through an ordinary opening or fan.

Changes may be made in the construction, arrangement, and disposition of the several parts of the invention without in any way departing from the field and scope of the same and it is meant to include all such within this application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In combination, a pipe provided with a lateral opening, a branch pipe surrounding said opening, a fan revolubly supported in said branch pipe, and means carried by said fan for creating a lateral draft toward said fan.

2. In combination, a pipe provided with a lateral opening, a branch pipe surrounding said opening, a fan revolubly supported in said branch pipe, arms carried by said fan, and lateral draft creating plates carried by said arms.

3. In combination, a pipe provided with a lateral opening, a deflector mounted in said pipe and extending above said opening, a branch pipe secured about said opening, a draft fan provided with means for creating a lateral draft and means for supporting said draft fan in said branch pipe.

1. In combination, a pipe provided with a lateral opening, a branch pipe secured about said opening and provided with a skirt flange, a rod extending across the interior of said branch pipe and provided with a socket, a fan post provided with reduced ends one of which is adapted to be seated in said socket, motor blades mounted on and turning said post, fan blades 16 secured to said post, a post provided with a cup socket, a bearing block mounted therein and provided with a socket adapted to re ceive the other reduced end of the aforesaid fan post, looped arms extending from said post, and means for connecting said arms to the aforesaid skirt flange.

5. In combination, a pipe provided with a lateral opening, a branch pipe secured about said opening and provided with a skirt flange, a rod extending across the interior of said branch pipe and provided with a socket, a fan post provided with reduced ends one of which is adapted to be seated in said socket, motor blades mounted on and turning said post, fan blades 16 secured to said post, a post provided with a cup socket, a bearing block mounted therein and provided with a socket adapted to receive the other reduced end of the aforesaid post, looped arms extending from said post, and means for adjustably clamping said arms to the aforesaid skirt flange.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
