To all whom fit may concern."
Be it known that I, ALBERT CAUCHEMONT, of 17 Rue de lAqueduc, in the city of Paris, Republic of France, architect, have invented Improvements in Suction Devices for Air, Gas, or Smoke Pipes, of which the following is a full, clear, and exact description.
The present invention `has for its object aV suction apparatus for air, gas or smoke'pipes.
This apparatus whichis arranged at the upper part of the exhaust pipe is characterized broadly by the fact that the outer air is unable in any case to enter the conduit surmounted by the device, whatever the direction of the wind may be.
This appliance utilizes the velocity of the external air for producing a suction eect in the discharge conduit and discharging externally, in a continuous manner, the air, gases or products of combustion contained therein.
This appliance does not comprise any movable parts, it obviates the noise and grating caused by rotating appliances and unlike them it is not exposed to being rendered inoperative by being immobilized by the corrosive action of smoke, or the collection of soot and thus presenting its aperture to the wind.
The object of the invention is illustrated by way of example in the accompanying drawing, in which:
Figure 1 is a vertical section of the apparatus on the line A-A. of Fig. 2V. Fig. 2 is a horizontal section of the same apparatus on the line B.-B of Fig. 1. Figs. 3 and 4 show the two parts of the apparatus separately and in perspective.
As shown in the drawing, the present ap-` paratus comprises a pipe a arranged upon the conduit to be ventilated and forming a continuation thereof. At its upper part this pipe is formed in such a manner as to constitute four wings b between each y of which there is a lateral aperture c. These openings which are directed toward the right hand or the left hand, at will, present a ltotal cross section at least equal to thatl of the pipe a.' The pipe a .thus arranged is located inside a kind of lantern formed by Va certain number of appropriately bent metal Y strips d each of which presents a lateral opening e arranged in the opposite direction to the openings c in the pipe a. y
Each of the strips d intersects withtheV adjacent strip,` in such a manner that the outer air in entering at one of the openings e is only able to reach the pipe a tangentially but not to enter it as indicatedV by the arrow 1 (Fig. 2.)
The strips d are iixed at their upper and lower parts upon two horizontal metal plates f and j" whichcompletely close above and below, the annular space comprised between the metal strips d and the pipe a. This latter is likewise' closed at its upper part, by a plate g.
The two parts of the apparatus are held in their relative positions by any appropriate iitting t.
The suction device thus constituted acts in the following mamier. `The air in entering the apparatus at one of the openings e reaches the pipe a' tangentially, as already stated. This air produces a suction effect inside this pipeV and the smoke, gases or vitiated air escape through theopenings c and pass to the annular space com rised between the said pipe and the strips of the lantern. Owing to the relative vacuum produced by the wind at the rear of the apparatus, the smoke or gases are drawn outside in passing through the apertures e in the lantern.
From the foregoing it will be seen that it is impossible for any admission or discharge of air, gas or smoke to take place otherwise than laterally and that in no case can the outer air enter the conduit and produce a i back draft.
The arrangements described above are given by way of example only; the forms, dimensions and detail arrangements may vary according to circumstances without thereby affecting the principle of the invention.
Clalms: Y 1.` A suctlon device for air, gas or smoke Vconduits, comprising a pipe closed at its upper end and having at said end hollow wings lying within the circumference of the pipe, the wings tapering downwardly and outwardly and each having a lateral opening, the combined area of the said openings being approximately equal to that of the pipe, and `a shell surrounding the upper end of the pipe and spaced therefrom, said shell being formed Vof angular strips and end plates, the strips overlapping one another with spaces therebetween forming openings, opening in a direction opposite to that of the openings of the wings of the pipe.
2. A suction device for air, gas or smoke conduits, comprising a pipe closed at its upper end and having at said end hollow wings flying within the circumference of the pipe 52 Qaesa and each provided with a lateral o` ening, and a shell surrounding the upper enc of said pipe and spaced therefrom, said shell being formed of angular strips and end plates, the strips overlapping one another with spaces therebetween forming openings opening in a direction opposite to that of the openings of the wings of the pipe.
3. A suction device for air, gas or smoke conduits comprising a pipe closed at its upper end and provided at said end with hollow wings having lateral openings, `and a shell surrounding the upper end of the pipe and spaced therefrom, said shell being formed of strips and end plates, the strips overlapping one another with spaces therebetween forniing openings opening in a direction opposite to that of the openings of the wings of the pipe.
l 4, A suction device for gas or smoke conL duits, comprising a pipe closed at its upper end and provided at its closed end with hollow wings each provided with an opening in its side, the combined area of the openings being approximately equal to that of the pipe, and a shell surrounding the upper end of the pipe' and spaced therefrom, the shell being closed at top and bottom and having tangential openings in its periphery, opening in a direction opposite to that of the wings of the pipe.
5. A suction device for gas or smoke conduits, comprising a pipe closed at its upper end and provided at its closed end with radial hollow wings lyingwithin the circumference ofthe pipe, each having an opening in its side, and a shell surrounding the pipe and spaced therefrom, the shell being closed at the top and bottom and provided with tangential openings in its periphery.
The foregoing specification of my improvements in suction devices for air, gas or smoke pipes signed by me this 14th day of October 1907.
