CHARLES A. MOORE, OFST. PAUL, MINNESOTA.

vnn'rrtarme APPARATUS.

Application filed March 18, 1924. Serial No: 700,061.

To all whom it may concern Be it known that I, CHARLEs A. Moore, a residing in St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Ventilating Apparatus, of which the following is a specification.

My invention relates to improvements in ventilating apparatus.

Its object is to provide a simple, durable and inexpensive apparatus of the present nature, the same being adapted to be readily installed in a building and to operate effectively not only in expelling foul air therefrom, but also in supplying fresh air thereto.

Another object is to provide for such results in an apparatus employing a single fan of conventional design.

With the foregoing and other objects in View, which will'appear in the following description, the invention resides in the novel combination and arrangement of parts and in the details of construction hereinafter described and claimed.

7 In thedrawings, Fig. 1 is a vertical, central sectional View of a device embodying my invention, the same being shown in connection with a room structure; Fig. 2 is a horizontal, central sectional View of the device shown in Fig. .1 and Fig. 3 is a rear elevational view of the same.

Referring to the drawings, it will be observed that the illustrated embodiment of my invention constitutes a unitary structure arranged against the inner wall of a room and adapted to set up a ventilating circulation of air therein.

The improvement includes a unitary casting consisting of a central conduit 10, a ring 11 encircling said conduit and a rim l2 encircling said ring, the conduit 10 and ring 11 being united by an annular web 13, and the rim 12, in turn, united with the ring 11 through the medium of

ducts

14, 15. This casting, just described, is placed in a wall 16 of a room. as shown :in Fig. 1, the outer margin of the rim 12 being fitted in a circular opening 17 in the wall 16. Capping the rim 12 and ring 11 is a cover plate '18, said plate being formed with a central aperture 19 therein, which registers with the inner opening of the central conduit 10. A motor 20, secured centrally of the aperture 19 by means of braces 21 reaching radially therefrom and attached at their outer ends to said plate 18, carries a fan B on the shaft 22 thereof, said fan being of conventional design and consisting of radial blades 23 similarly pitched. The fan blades 23 turn in the limited space between the inner end of the conduit 10 and the cover plate'18, the ends of said blades 23 projecting beyond the diametrical limits of said conduit. It will now be observed that the inner opening 'of the central conduit 10 embraces a circular, central area of the fan 13 at one side thereof and that an annular area of said fan at itsopposite side is embraced by an opening 24 that amounts to a second conduit in the combination of the run 12, ring 11 and cover plate 18. Said opening 24 is formed between the ring 11 and the inner flange 18 of the cover plate 18..

From the foregoing, it will be under stood that the fan B, turning in one direction, will draw air from without through the conduit 10 and the center of the fan and force said air into the room; also that said fan. will draw air from the roomthrough the

ducts

14, 15 and the margin of the fan and force said air to the outside through the conduit formed by the rim 12, ring 11' and cover plate 18. Turning in the opposite direction, said fan B withdraws air from the room and expels it to the outer air through the center of the fan, while air is drawn' from the outside into the conduit formed by the rim 12, ring 11 and cover plate 18 and thence forced into the room through the ducts .11, 15. I v

Communicating with the

ducts

14, 15 are "pipes 25, 26, said pipes being fitted. with

dampers

27, 28 and providing for the Withdrawal or introduction of air from and to the room at the ceiling of floor thereof, as may be desired.

Among the several advantages making for eifective ventilation, and compactness, simplicity andlow cost of construction, the single conventional fan serving the dual purposes hereinbefore described is an important feature.

Changes in the specific form-of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.

' Patent is:

1. Thecombination with a room-and ventilating fan therefor having radial blades,

a conduit opening at its outer end into the outer atmosphere and at its inner end in close proximity to the fan, said inner end of said conduit being proportioned to embrace a portion of the area of said fan, a second conduit opening at its outer end into the outer atmosphere and at its inner end adjacent to the fan said inner opening of said second conduit being arran edin opposition to the inner opening said first conduit and proportioned to embrace a different portion of the area of the fan, and a duct leading from a part of the room removed from said fan to the side-of the fan opposite said inner opening of said second' conduit.
