P. J. BODE VENTILATOR Oct. 14, 1930.

VENTILATOR Application filed September 4, 1928. Serial No. 303,674.

The object of my invention is to devise a ventilating system and the structure for the same to be used in both buildings and vehicles. A further object is to devise a ven- 5 tilating system, which will automatically remove the foul air from the room or vehicle, and displace the foul air with fresh air, and thereby produce a circulation of air. I A still further object is to devise a ventilating mechanism that is simple in construction, made of few and simple parts, that lend themselves readily to multiple production.

With these and other objects in view, my invention has relation to certain features of construction and arrangement of parts, as will be hereinafter more fully described, claimed and illustrated in the drawing, in which n Fig. 1, is a front elevation of a portion of a vehicle body with my device attached.

Fig. 2, is a perspective view of the con duits used in my device, and

Fig. 3, is a fragmental, longitudinal, sectional elevation of the top and front of a vehicle with my device attached.

][ have illustrated a vehicle in the drawings, but do not desire to be limited in the application of my device to a vehicle.

The drawings illustrate a closed body such as a sedan or coupe in which the ventilation problem is a serious one when the windows and doors are closed, as is the case in in clement weather. Numeral 4 designates the body generally having the front 5 and the top 6. Numerals 7 indicate the ribs of the top. My device is secured to the ribs 7 by means of the angle irons 8 and by passing through a perforation 9 in the front 5, is secured to the front. In a similar way it is secured to the back not shown.

My ventilating device is preferably made of sheet metal, rectangular in shape and so conformed as to have the sides 10, and the partitions 11 and 12. This divides the entire structure 13 into 3 flues, 14, 15 and 16. The fines 1d and 16 are on each of the corresponding ends closed by the stops 17 and 18. The sides 10 are perforated with the perforation 19. Tu the bottom plate 20 of the structure 13 beneath the flue 15 are formed the rectangular openings 21, having the flaps 22 immediately above them. These flaps are bent at a slight angle to the plane of the bottom structure 20. The structure 13 is positioned as shown in Figures 1 and 3 with the bottom plate 20 positioned downwardly. The ends of the sides 10 andof the bottom plate 20 as well as the partitions 11 and 12 extend forwardly beyond the front of the body as shown in Fig. 3. In the-plane of the body front are operatively positioned the gate valves 23, which are pivotally secured between the sides 10 and partitions 11 and 12, so that they may be conveniently, manually rotated by the operator. When the gate valves 23 are in the position shown in Fig. 3, the lines in which they are p0sitioned are closed from the front. When the valves are opened they lie against the surface of the bottom plate 20.

The direction of circulation of the air is indicated by the arrows on the drawings. The circulation is the following. The fresh air from the outside enters the flue 15 from the front, passes through the flue 15 and out the rear end of the flue 15. This passage of the air in this fine over the rectangular openings 21, produces a partial vacuum or suction, which causes the foul air immediately adjacent the bottom plate 20, to rush through the rectangular openings 21, into the fine 25, to be carried out the rear end of the fine 15.

When my device is placed in a building, it may be so located as to have the flues parallel to the prevailing wind in order to facilitate the circulation. The flaps 22, prevent the fresh air passing through the flue 15 from entering the rectangular openings21, in any appreciative amounts.

he air entering the fines 14 and 16 from the front end passes rearwardly, but cannot pass out the rear ends on account of the stops 17 and 18 and is forced therefore to move laterally through the perforation 19 into the car. in the car, the fresh air entering through the perforations 19 and making its exit through the rectangular openings 21, through the rear of the flue 15.

This action is facilitated by the movement Thus circulation is established of the car in a forward direction. When the car is not in motion or when my system is applied to a room, it may become necessary to produce a forced draft to promote the 'circulation.

For this purpose I provide the pipe 24, which has anyconvenient entrance in the flue 15, as shown in Fig. 3, the end being bent rearwardly, so'that when the air is forced into the flue 15, through the pipe 24:, it will be ejected longitudinally rearwardly in the flue 15. When the air is exhausted from the flue 15 in this manner the foul air will pass through the rectangular openings 21 in the same manner that it did through the natural draft. The rem-oval of the foul air in the manner described will cause a circulation of a natural draft through the flues 14 and 16 as was the case with the natural draft.

Numeral 25 indicates a fan, which may be conveniently positioned and actuated in any desired manner, and which is in fluid communication with the pipe 24.

What I claim is In combination with a vehicle, a ventilating mechanism comprising a flue open at both ends and having openings in the lower faces with flaps immediately above them, a fan in fluid communication with said flues, and a plurality of flues open at one end and closed at the opposite ends and having lateral perforations therein, all of said flues extending forwardly beyond the front of said body, valves positioned in the plane of the front of said vehicle and in said flues.

In testimony whereof I aflix my signature.

PETER J. BODE.
