The present invention has for object an aspiratorventilator apparatus which can be used either for salubrity'purposes by renewing the air in any medium, or for evacuating i vapors and smoke from furnaces or fire-places in general whilst accelerating their draught.
Thisapparatus is characterized bythe combinatibn of the following constituent parts:
- 1. A central cylindrical body open at both l0 ends and provided with apertures directed upwardly for the entrance and ascent of the outer air; l
2. A cap provided with outlet orifices at its upper part and with air inlet rilices at y' 15 its lower" part, in coincidence with thel orilices or apertures of the cylindrical body.
The advantages, of this apparatus are the following 1. Absence of any rotary movement which, 20 in certain apparatus, after a very short time, prevents them from rotating owing either to rust, or owing to Bthe agglomeration of'soot, or again owing to the corrosive action of vapors, smoke and the like. 2. No longer any rain inthe chimneys, the
apparatus being covered; 3. Driving back of smoke renderedimpossible, as the atmospheric air cannot in any case enter the chimney, since the most violent 1y accelerates the draught of the latter wit outever causing any driving back of smoke, carbon monoxide, vapors or smell; 4. Easy sweepinggowing to the fact that as j the cap is removable, it uncovers the central cylindrical body. j `The invention will be described, by way of example only, with reference to the accompanying drawing in which :l
Figffl islan elevation of a form of construc- Figs 2 a verticalv section of the sameappgratus.
' illustrated indrawing, this apparatus comprisesa cylindrical-body aarranged on 'the top of'the'pbject adapted to receive it, a closed vehicle for instance;
About this cylindrical body a are provided cut out aperturesfb so formed that the iiaps lo lcutout atl thetop remain: attached -at the bottom to the cylindrical body and are then bent inwardly. e A
A kind of cap c,.pref erably removable, covers' the upper part of the cylinder a.
This cap pleated as an accordion is closed at it-s upper part by a conical cover and its lower part is assembledwith the cylindrical body a ;A moreover, 'ut out apertures d with bent flaps are provided in the upper part of the cap; finally, other apertures e are provided in the lower part of the said cpby striking intongues e which serve as ba es and opposite these latter cut out apertures are provided penthouses f open at the bottom.
A fla-nge g connects in a fluid-tight manner the cylindrical body a with the roof h of the vehicle for instance.
The bottom part of the cylindrical body a is connected to a collar z flaring at its lower part and provided with cut out apertures y'. This gollar a' is secured in the ceilingk of the ve- Vithin the flared portion of the collar i is ceiling fixture Zsupporting the lamp and surrounded by an apertured ring m. I
Vent holes n are provided betweexrthe roof k and the ceiling lc.
The wind enters through one or the other of the penthouses f, according to the direction of running of the vehicle, and thus causes the rapid evacuation of the fumes', smells and vapor of the vehicle through the two outlets d provided in the cap. Y
These two outlets d being formed on the sides of the apparatus, neither rain, dust or ,the like can enter'the apparatus.
Moreover, the orifices n formed in the boti tom' portion of the apparatus allow the suction of the foul air which may happen to be 1 between the ceiling lo and the roof it, this attenuating the caloric effect of the solar'ray-s, in summer and the action of tle-cold in. winter; finally these orifices regulariz'e thetemperature and avoid the expansion and shrinking of the woodwork. This apparatus will preferably'be made non-oxidable ena-melled sheet-iron.' L
The forms, details, accessories', materials and dimensions o f this apparatus can of course be varied without departing thereby romthe principle of the invention.
'I claim A ventilator of the character described 5 comprising a, cylindrical body having the respective ends open and having the lower end in communication with the part to be ventilated, flaps struck inwardly and extended upwardly to leave openings in the body for ad- D mitting fresh' air, a cap arranged. about the upper end of the body and including a. conical top and a depending flanged portion accordion shaped in vertical section with the lowermost edge secured to the outer surface of the body, the upper part of the flanged portion having an exit opening therein, flaps struck upwardly at ypoints near the lower edge of the flanged portionk and at points near the first flaps so as to leave air admission 5,70 openings and hoods secured to the outer surface of the flanged portion of the 'cap and about the last mentioned openings and having the lower ends open.
The foregoing specification of my Improvements in aspirator-ventilator apparatus signed by me this 8th day of Decemi ber, 1927.
