Referring to thedrawings, in Fig. 1 a perspective view of a partof abuilding structure is shown 6 Claims. (Cl. 98 33) 2 comprising the studding I0, the joists H, the rafters I2 and the roof portion 13. This is of usual construction. Mounted on a cross member [5 secured between adjacent studs I0, as by nails I6, is one embodiment of the ventilating device 20 of this invention, the same being shown in perspective. As shown, this device can be completely disposed between adjacent members of studding and of course could be of diiierent' sizes. The applicants device comprises a housingv or casing 2|. This housin 2| is box-like and generally rectangular in horizontal and verticalsection and is made of a sheet material, such as wood or metal. The said housing has a bottom 2 la secured to cross piece l5, sides 2 lb, a rear-wall 21c and an open top 21d. The said housing has upper and, lower front openings Zle and 2| f respectively. The upper front portion 2 lg adjacent the upper edge of said housing 2| is recessed slightly. A pyramidical cap 22 is provided which extends upwardly from and fits about the upper edge portion of said housin 2|. The said cap has a cylindrical portion 22a. A discharge duct 23 isprovided shown as of cylindrical form which extends upwardly between the studding into the attic or upwardly through the roof. If extending through the roof, as shown in Fig. 1, said discharge duct may be provided at its top with a cap 24. I Extending transversely across the front of said housing are spaced horizontal cross members or bars 25, 26 and 21 secured adjacent the top, ad jacent the middle and adjacent the bottom thereof respectively. These cross members may be made of wood, are rectangular in vertical section and may be secured to the sides of said housing in any suitable manner, as by nailing. The cross members 25 and 26 serve to define the upper and lower openings He and 21f. Secured to and extending between members 25 and 26 in the upper opening 2| e are a plurality of spaced electrical heating coils or conductors 28, forming a heating unit. Electrical current to said coils or conductors is controlled by a toggle switch 29 disposed in a chamber in member 26 and havin a forwardly projection handle 29a. Electrical current is provided through a suitable conductor 30. Secured to the inner side of cross member 25 by screws 32 is a hinge 35 to which is swingably secured a damper 36. Said damper is made of sheet material, such as metal. Said damper is moved in an arc backwardly and upwardly and said hinge is so constructed as to position said damper at either end of the arc in which it moves or at an intermediate point. For movement of said damper, a handle 3! is pivotally secured to the same adjacent its lower end by a pivot 24. Said handle is formed of a bar or rod extending to the front of housing 2i and having an upturned end. Damper 36 is disposed in the upper front of casing 21 and at the rear of coils or conductors 28.

Referring to Figs. 3 and 4, a fan housing 42 is provided and is secured in the lower part of casing 21 and is spaced inwardly somewhat of the front and back of said housing. Said fan housing is preferably made of sheet material, such as metal, and has a generally cylindrical shape with an upper portion curved upwardly to form a duct 420 leading into the upper portion of casing 2|. A plate 43 extends across casing 2| through which the duct 42c passes and by which said duct is positioned. A circular air intake opening 42d is provided in the front 42a of the said fan housing. Brackets having circumferentially and equally spaced radial arms are secured exteriorly to the front and back of the said fan housing respectivelyby bolts 49 and are centered thereon respectively in alignment with one another. Said brackets are secured to the said fan housing by screws 48. An electrically driven motor 41 is provided and is disposed in fan housing 42 and secured to the front bracket 45 by bolts 48. Motor 4! is provided with an armature or driving shaft 49 which is journaled in said brackets 45. Positioned about said motor and secured to shaft 49 is asquirrel cage type fan 50 rotating freely about motor 41. A toggle switch 44 for controlling motor 4'! is provided.

A modification of the above described construction is shown in Figs. 5 and 6. Secured to the front of the lower chamber is a face plate 5| provided with a circular opening 5m centered therethrough and forming an air intake. A motor 52 is provided having an armature or driving shaft 53 extending forwardly therefrom. Said motor is positioned centrally of opening 51a and disposed in the lower front of casing 2|. Motor 52 is secured by diagonally extending and cross braces 54 having their outer ends bent at right angles and secured respectively to cross members 26 and 21 and their inner ends similarly bent and secured respectively by bolts 58 to the housing motor 52. A propeller blade fan 59 is secured to shaft 53 and is driven thereby. A toggle switch 44 for motor 52 is provided secured to member 21. A different form of handle 31a is provided for damper 35 and is of upwardly curved form and secured adjacent the upper end of said damper.

A deflecting plate 60 is provided at the rear of fan 59. Said plate extends substantially the width of said casing 2|. It is secured by screws Bl at its lower edge portion to cross member 27. Said plate is inclined upwardly and rearwardly and is secured in any suitable manner, as by welding, to the rear of the casing 2| at the upper'portion of its lower chamber.

Overlying the front of housing 2! is an ornamental grille provided with a plurality of openings formed of spaced vertical bars 66 in its lower portion and spaced radially extending bars 61 in its upper portion to permit the free movement of air therethrough. Openings 68 and 69 are provided in the said grille to respectively accommodate toggle switches 29 and 44. Said grille is secured to said housing 20, as by screws 69a or other commonly used fastening means.

In operation, the applicants device will be recessed in a wall, as shown in Fig. 1. Housing 2| is conveniently disposed between adjacent studding i0 and duct or conduit 23 extends upwardly between said studding. Cross piece [5 can be located at any desired height. Only the ornamental grille will be visible on the wall of the room, such as a bathroom or kitchen. The discharge duct may lead into the attic of the dwelling or building or it may extend up through the roof. This single unit ventilating device has a high degree of utility in performing thre related functions. By positioning the damper into a forward'or verticalposition, as is shown in Fig. 6, the discharge duct will be open to its full extent. Then by turning on the blower or fan, air will be withdrawn from the room through the opening into the lower portion of the casing 2| and it will be forced upwardly and out through the exhaust duct 23.

When the damper is pushed backwardly to its full extent, as shown in Fig. 4, the discharge duct will be closed off completely. When the fan or blower is turned on it circulates the air in the room by; drawing it in through opening 2|] into the lower portion of the casing 2| and blowingor forcing it back into th room through the upper opening 2 id. If desired, the heating coils 28 may be turned on when the air is circulated back through the room. This air. passesthrough the heating coils and is warmed in its passage. Thus this device may serve as an auxiliary heating unit.

By positioning the damper at any point between its fully opened or vertical position. and its fully closed position, the amountof air discharged or circulated can be readily adjusted to the comfort of the operator. Also by positioning the damper, as shown in Fig. 4, any back drafts occurring when the unit is not in use are prevented from entering the room.

Thus it is seen that I have provided a ventilating device with highly desirable features which is compact, easily installed and highly efficient in its operation. t is conveniently disposed between studding in a wall. It can be used to quickly withdraw odors from a room or moisture laden air or it can circulate air as it is or warm it as it passes through heating coils. It can, as shown and described, fit conveniently between the studding of the building. Thi device has particular usefulness in a bathroom or a kitchen.

It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the-parts, without departing from the scope of applicant's invention, which generally stated, consistsin a devicecapable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.
