Patented Feb. 13, 1934 UNITED STATES PATENT OFFICE This invention relates to a ventilator and more particularly to a window type and has for its primary object a design of apparatus that is more simple in construction and which will possess I many advantages contributory to higher efficiency thereof.
An object of the invention resides in the design and oo-relation of the parts so that the ventilating action of the ventilator may be automati- 1o cally controlled in the raising and lowering of a window sash according to climatic conditions.
Another object of the invention resides in the association of the companion louvers whereby the recirculating of the air may be increased or decreased in proportion to the increase or decrease of the flow of air from the outside of the room.
A feature of the invention resides in the novel manner of adapting the ventilator to a window frame in operative relation with the window sash.
Besides the above my invention is distinguished in the arrangement in a unitary apparatus of a humidifier, a heater, a fan and a filter device in a novel relation so that in a very efiective manner air may be drawn from the outside to recirculate through the apparatus and heated, cooled or humidified, depending upon what is desired.
With these and other objects in view the invention will be better understood from the following detailed description taken in connection with the accompanying drawings, wherein:'
Figure 1 is a perspective view of the ventilator in applied position.
Figure 2 is a cross sectional view of the ventilator at a point through the recirculating louvers.
Figure 3 is a horizontal sectional view through the ventilator at a point directly above the shut.- ter.
Figure 4 is a detail sectional view of the upper portion of the damper plate, portions of the as- 'sociated parts of the ventilator being shown in sections.
Figure 5 is a longitudinal sectional view through the center of the ventilator.
Figure 6 is a detail sectional view of the upper portion to one of the shutters showing associated parts of the ventilator in section.
Again referring to the drawings illustrating one of the many forms of my invention, the numeral 1 designates the ventilator which is illustrated as a window 'type and supported by the window frame 2 contiguous to the window sash 3 so that in the raising and lowering of the sash the ventilator will be automatically manipulated to control the ventilating action thereof.
To accomplish a snug fit between the casing 4 of the ventilator and the window frame and window sash, I provide filler plates 5 which are provided with clamps 6 slidably related with the casing 4. The casing 4 includes a rear end wall '7,
a front end wall 8, side walls 9 and a movable 60 top 10 all of which are economically manufactured from metal stampings. I wish it to be understood that this casing may be felt lined in any suitable desired manner to make the same sound proof or for any other desired reason. As 05 I-consider I am entitled to basic protection for the novel construction and association of the main parts of the invention I am not stressing the details of construction as the various component details may be manufactured and designed in many other ways than illustrated.
The front end wall 8 is provided with a plurality of inlet louvers l1 defining air inlets 12. The rear wall '7 is provided with outlet louvers l3 defining outlets 14. The side walls 9 are provided 7 with recirculating louvers 15 defining recirculating openings 16. Associated wtih the louvers 15 in'both the side walls are a pair of shutters 17 illustrated as plate 19 carrying felt pad 20 arranged to effectively close the openings 16 or partially close the same to control the circulation of air through the openings 16. For the purpose of progressively and gradually closing the openings 16 the plates 19 are pivoted to the casing to one side of the openings 16 as shown at 21 and at the pivot 21 each plate is provided with an arm 22 whereby the plate may be swung about its pivot for covering and uncovering the opening 16.
A damper plate 23 is associated with the louver 11 andthis plate 23 is under direct control of the window sash in a manner now to be described.
The plate 23 is provided with ears 24 pivotally mounted on a rod 25. A control spring 26 has an operative connection with the plate 23 to swing the same away from the louver 11. This plate 23 engages under the sash 3 so that in -the raising and lowering of the sash the plate 23 will be moved towards and away from the louvers 11 for controlling the amount of air passing through the inlets 12.
As I wish to automatically control the recirculation of the air in a room according to the amount of air passing through the ventilator on the outside, I have provided the plate 23 with levers 2'7, one for each shutter 17 and arranged to operatively engage the arm 22 when the plate 23 has been moved into a predetermined relation with the louvers 11. In other words, the lever 2"! will engage the arm 22 for swinging the shutter away from the louvers when the plate 23 has reached a definite air cutting off position in relation to the louvers 11. Thus, it will be appreciated that in proportion to the window sash being lowered to cut off air from the outside the recirculation of air within the room through the openings 16 will be proportionately increased.
To one side of the louvers 11 and 15 is an air circulating device illustrated as a fan 28 driven by a motor 29 that is carried by a support 30. Associated with thefan is a deflector 31 and arranged between the fan and the louvers 11 and 15 is an air filtering device 32 which may be of fine wire gauze, paper or other types of filtering elements. This filtering device 32 is preferably movably mounted in beads 33 carried by the casing so that the same may be readily renewed. Interposed between the fan 28 and the louvers 13 is a suitable type of heating device 34 and any suitable type of humidifier 35. I have illustrated the humidifier 35 in the form of a tray to support water or ice cubes, whichever is desired. I have not illustrated the electrical connections or the electrical devices for controlling the operation of the heating element or the fan motor as this may be designed in many ways, particularly to accomplish many specific results.
In the use of the apparatus the casing is arranged in place and the filling plates 5 slid into position to properly connect the casing to the window frame. Current is then switched onto the heating device and to the motor 29 which sets the apparatus into operation for drawing air from the outside through the air inlets 12 and forcing the same through the filtering device and out the air outlets 14. When the amount of air passing through the apparatus from the outside is too great the lowering of the sash will automatically swing the plate 23 for cutting off the supply of air 'from the outside and when the plate 23 has been depressed great enough it will automatically operate the shutters 17 for creating'a recirculation of warm air within the room. It is to be understood that the direction of travel of the fan may be reversed for forcing air from the room into the exterior or drawing air from the exterior and forcing the same interiorly of the room. It is of course to be understood that the heating device may be used in conjuction with the humidifier or one used independent of the other.
Having described my invention, what I claim is:
1. In combination with a window sash, a ventilator having a plurality of inlet louvers at one end thereof and a damper operatively connected to said window sash to be operated in the movement of the window sash to automatically control the amount of air passing through said louvers.
