Description
Dec. 9, 1930. A. CAUCHEMONT 1,784,783
VENTILATING DEVICE Filed Feb. 28, 1929 Patented Dec. 9, 1930 PATENT OFFICE ALBERT CAUGHEMONT, F PARIS, FRANCE VENTILATING DEVICE Application filed February 28, 1929, Serial No. 343,294, and in France March 7, 1928.
In my French Patent No. 613,853 of April 1, 1926, I described a ventilator for the ventilation of conduits or smoke conduits in which the plates, constituting the shell were l disposed in such a way as to provide only a single lateral opening between each of them turned solely from the right to the left or from left to right.
The present invention has for an object an improvement relating to such type of ventilator and which consists essentially in the arrangement of double lateral outlets. To this end the plates constituting the shell of the apparatus leave lateral openings between them turned both to theright and to the left. This arrangement has for effect to prevent the direct entry of wind, rain, snow or hail in the central pipe and to permit a double evacuation of that previously existing. The invention will be more readily understood with reference to the accompanying drawing, given by way of example, and in which Fig. 1 is avertical section of my apparatus taken along the line 11 of Fig. 2;
Fig. 2- is a horizontal section taken along the line 22 of Fig. 1;
Fig. 3 is a sectional detail of an apparatus constructed according to my French Patent No. 613,853; and
Fig. 4 is a sectional detail relating to Fi 2.
like reference characters indicate similar parts throughout the several views of the drawing.
Referring to the drawing more in detail,
and more particularly to Figs. 1, 2 and 4:, my
a paratus comprises a pipe at placed above t e pipe to beventilated and forming a pro- 4 longation thereof.
Said pipe which may be terminated at its upperpart by a conical nozzle 6, penetrates in part the interior of a cage formed by a first series of blades of metalor other suitable material 0 f suitably bent or curved to form a sharp edge and in a way to allow between each of them an opening 0? turned directly inside. A second series of plates 0 0 g placed opposite the previous openings at a distance sufficient to leave before each a delivery passageway e is also provided which are provided on each side with a lateral outlet opening (Z 0Z which face in op= posite directions.
The plates 0 0 9 must be arranged to overlap the opening d sufficiently in order that the wind, rain, snow or hail cannot penetrate directly into the central pipe a. Said plates are preferably terminated laterally by a flap p '1) turned outwardly.
The plates 0 f and 0 c g are fixed at their lower part on a plate and at their upper part on a plate Z surmounted or not by a cone m.
The two parts of the apparatus, cage and pipe, are maintained in their respective positions by means of a bracket arrangement m.
The above disclosed apparatus operates as follows:
When the wind comes to strike against one of the outside plates 0 c 9 the said plate, by its disposition and by the disposition of the flaps p p prevents, whatever be the violence of the wind, entry into any of the interior openings d and it spreads, on the contrary, to the right and to the left, creating a first vacuum zone at the double lateral outlets d and d When it comes to move through the space existing between the two plates 0 c g it meets the second series of plates 0 7 against which it abuts and becomes spread out as previously and creates a second vacuum zone due to its rapid passage in contact with the orifices of the thin wall of the opening d.
All the vacuum produced at the orifices d and (l of the double lateral openings is exerted on the totality ofair or gases contained indthe pipe a which become drawn to the out- S1 e.
While I have disclosed what I deem to be the preferred form of my device, I do not wish to be limited thereto, as there might be many modifications made in my invention by those skilled in the art without departing from the spirit thereof as comprehended within'the scope of the appended claims.
Having described my invention what I claim as new and desire to secure by Letters Patent is:
1. A ventilating device of the type described comprisin an outer set of elements disposed in cage ormation each of said elements having a flange at each end thereof, said flanges being so disposed that the opposite edges of two adjacent elements form an outwardly converging passage for the ingress of the wind, a second set of elements within the first set and concentrically .disposed with reference thereto, each element of said second set comprising two members set at an anglle .to each other, said angle diverging outwar and the contiguous members of two adjacent I elements of said second set being so placed as to form an outwardly converging passage which opens behind an element ofsaid first set, whereby the egress of air through the last named passage is made easier and may take place from the ri ht and from the left.
2. A ventilating evice as set forth in claim 1, wherein one part of each of the two-' part elements is substantially radial and the other part is substantially in tangential relation with reference to an irna inar cylinder passing through the apices o sai two-part elements.
In testimony whereof I have signed this specification.
ALBERT CAUCHEMONT.
