ATTORNEY Patented Aug. 13, 1929 UNITED STATES WILLIAM HAGKEY, F MONROE, WISCONSIN.

VENTILATING DEVICE.

Application filed June 16,

This invention relates to certain novel improvements in a ventilating device and has for its principal object the provision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

It is among the objects of my invention to provide an arrangement for ventilating a closed chamber such as a closed automobile body, a room in a building or the like.

- Another object of the invention is to arrange the device in such a manner that a conduit will be provided through which air from extraneous sources may be directed so as to withdraw air from the chamber through a conduit disposed in juxtaposition to the first named conduit and having communication with the first named conduit adjacent the rear end thereof.

Another object of the invention is to provide a means whereby air passage through the device may be expeditiously controlled.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, showing the preferred form of construction and in which:

Fig. 1 is a side view depicting my improved ventilating device in elevation and showing the same associated with the upper portion of a chamber;

Fig. 2 is a longitudinal sectional view of the device as illustrated in Fig. 1;

Fig. 3 is a sectional view taken substantially on the line 33 on Fig. 2; and

Fig. 4 is a sectional view taken substantially on the line 44 on Fig. 2. I p

In the drawing wherein I have illustrated the preferred embodiment of my invention, I depict my device as embodying a housing 10 which in the present instance has a partition 11 provided therein. Thepartition 11 co-operates with one side wall of the housing 10 to provide a compartment 12 and thus a compartment is defined between the other side wall 13 and the partition 11 and this compartment is indicated by 14 in the drawing. As is illustrated in ig. 2, the partition 11 does not extend throughout the entire length of the housing 10 but is foreshortened as indicated at 15 and a wall 16 is provided at this point. It is to be understood that while I have described in the foregoing my 1928. Serial No. 285,825.

device as having been arranged so as to embody but one body the device may be arranged so as to provide two bodies arranged in j uxtaposed relation so as to provide a construction analogous to the foregoing.

At the end of the chamber 12 opposite the wall 16 an opening 17 is provided. In the wall 16, a plurality of openings 18 are provided which are preferably disposed in circulararrangement as clearly illustrated in Fig. 4. One end of a shaft 19 is .journalled in an opening provided at substantially the center of the circular disposition of the openings 18. A hub 20 is mounted on this shaft 19 which is disposed in juxtaposition to the wall 16 and blades 21 are provided on this hub which are adapted to co-operate with the openings 18-so as to control passage therethrough. When the shaft 19 is moved in the manner hereintofore set forth, blades 21 may be moved over or away from the openings 18 so as to control passage through these openings.

The foreshortening of the partition 11 p10- vides a compartment 22 Which is in open communication with the compartment 14. At the rear end of the compartment 14 in alignment with the compartment 22, a curved portion 23 is provided which serves to facilitate the deflection of air passing through the c0mpartment 14 into the compartment 22.

The end'wall 24 of the housing 10 has openings 25 provided therein that are adapted to be aligned with the openings18 in the wall 16 an these openings 25 are also disposed in circular formation as clearly illustrated in Fig. 3. The shaft 19 also extends through this wall 24 and disposed around the shaft 19 on the portion thereof extraneous the wall 24 is an elongated hub 26 which has blades 27 provided thereon that are adapted to be moved into or from registration with the openings 25 so as to control passage therethrough. As clearly illustrated in Fig. 1, a handle 28 is provided on the hub 26 and a handle 29 is provided on the outer end of the shaft 19. By gripping the handle 28, the blades 27 may be moved so as to regulate the size of the openings 25 and thus control the air passage therethrough and by gripping the handle 29 and moving the shaft 19 a similar control may be provided for the openings 18.

As clearly illustrated in Fig. 2, the wall 13 of the body 10 hasa plurality of openings 30 provided therein, the utility of which will be made apparent presently.

As has been stated, this device is adapted to be used for ventilating a chamber such as a closed automobile body or a room of a building or the like. In the event the device was used in association with an automobile body, an opening 31 would be provided in the body in alignmentwith the opening 17 and an opening 32 would be provided at the other end of the body in alignment but spaced from the openings 25. The opening 31 would preferably be provided at the forward end of the vehicle. Therefore as the vehicle moved forward, air would pass through the opening 31 and the opening 17 into the chamber 12 and would pass therefrom through the openings 18. The positioning of the blades 21 relative to these openings 18 regulates the speed of air escapement. The air thus passing through the openings 18 would pass into the chamber 22 and thence on through the openings 25 and the opening 32 it being apparent that the speed of air escapementthrough the opening 25 would be controlled by the location of the blades 27 The air rushing through the chamber 22 would tend to draw air from the chamber 14 since these chambers are in free communication and air drawn from the chamber 14: would be drawn through the openings 13. Thus it is apparent that the room or other chamber with which this device is associated will have the stale air extracted therefrom which will obviously cause the entrance of fresh air. It is apparent that the independent regulation of the air passage through the device provided by the independent control of the blades 21 and 27 will permit very accurate control of the air passage through the openings 30. It is also apparent that the device is simple in construction as no moving parts are required and it is obvious from the foregoing that economy ofmanufacture will be attained. I a

In the foregoing description I have described my device as being mounted interiorly of the body with which it is associated and have described openings in this body which communicate with the openings 17 and 25. It is to be understood, however, that the device might be arranged such that the openings 17 and 25 will be disposed exteriorly of the body and obviously in such a construction the

openings

31 and 32 will not be required.

In addition to the foregoing wherein the device has been described as being employed for removing air from a body it is to be understood that by closing the openings 25 the direction of air travel through the openings 30 will be changed and thus fresh air will be forced into the room or body. In the event this device were used in connection with an automobile or the like two such arrangements might be employed, one being located on each side of the body. If such a construction were employed one of the devices might be used to force fresh air into the body in the manner just described and the other of the mechanisms will be arranged so as to withdraw the air in the manner hereintofore described or, if desired, both of the devices might be arranged so as to withdraw air or both might be arranged so as to force in fresh air.

While I have illustrated and described the preferred form of construction for carrying my invention into efiect, this is capable of variations and modifications without departing from the spirit of the invention. I, therefore, do not want to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.
