DEVICE FOR CONTROLLING FROM A DISTANCE THE PASSAGE OF GAS.

Specification of Letters Patent.

Application filed August 19, 1908.

Patented June 4, 1912. Serial No. 449,354.

To all whom it may concern Be it known that we, ALBERT MAURICE AUBERT and JEAN MARCEL AUBERT, citizens of the Republic of France, residing at 135 Route de Versailles, Billancourt, Seine, in the said Republic, have invented certain new and useful Improvements in Devices for Controlling from a Distance the Passage tion.

This invention relates to a device for controlling from a distance the passage of gas; the said device being operated with aid of three electric leads, that is to say, the device comprises two electromagnets which are thrown into circuit alternately by turning a suitable switch, one of these magnets determining the admission of gas to the burner and the other determining the cutting off of this gas.

The device consists essentially of a valve designed to control a gas passage and arranged in such a manner that it is actuated by a ball adapted to engage its lower face, said ball being actuated through the intermediary of a conical surface on a cylindro-conical body of revolution, the lateral displacement of the latter in one direction actin to raise the valve from its seat, while the displacement of said body in the opposite direction permits the return of the valve to its seat under the action of a spring.

The accompanying drawing is a vertical section of one form of device embodying our invention, the body of revolution being represented as in motion.

The apparatus comprises a tubular casing a in the upper part of which is screwed a tube 7) which holds in place the seat 0 of the valve (Z; the latter is provided with a collar 6 of any suitable form and material, is guided by a tubular extension f and is held on its seat by a spring g. v

Into the respective sides of the casing 41. are screwed caps h and h containing bobbins, i, i of solenoids j, j. Within the hollow bobbins slide the solenoid cores is, is; the two cores are fixed to the opposite faces of a disk Z having a central conical portion and two cylindrical portions m, m of difierent radii, on its periphery. Accordingly as current is transmitted through solenoid 7' or solenoid j, the disk Z is moved to the right or to the left. Preferably the coreslc 7c and the disk Z are bored axially so that air may pass from one end to the other when the disk is displaced under action of one or other of the solenoids.

Extending co-axially through the seat 0 of the valve is a short tube a in which is lodged a ball a resting on the disk Z. The diameter of this ball is such that when the ball a rests on the cylindrical portion on of the disk, the valve 4% can rest upon its I, 7 seat, but when the ballrests upon the cylindrical portion on of the disk the valve d is fully opened, while when the ball rests on the conical portion of the disk as shown in the figure the valve occupies an intermediate position. energized the valve is lifted, while when the solenoid y" is energized the valve is able to.

return to its seat under action of spring 9. A simple switch having two poles suflices to control this valve from a distance. When When the solenoid is y the valve is open the gas passes through the connection at 0 to that at p by way of the orifices 1' in the valve seat 0 and the orifices g in the tubular extension f. Inasmuch as the ball a has considerable play in the tube 0 gas can also pass through this tube; the direction of the passage of. the gas is shown by the arrows.

It will be seen that the cylindrical parts m m of the disk keep the valve stable in its open or closed position, so that when it is open vibrations do not cause it to shut. Moreover, the apparatus is exceedingly sensitive since friction is avoided by the use of a ball and a freely movable body of revolution.

The solenoids or electromagnets and their armatures may be of any suitable form and may be attached to the casing in any suitable manner.

Having thus described the nature of our said invention and the best means we know ofcarrying the same into practical effect, we claim:

1. Mechanism for controlling gas from a distance, comprising a casing, tubes attached thereto for the admission and escape of gas, a cut-off valve, a spring to press said valve on its seat, a freely and axially movable body having a conical surface of revolution between cylindrical surfaces of dilferent diameters axial therewith, said body maintained distant from the walls of the casing to permit'the passage of gas around and past the body under all conditions of operation, a round faced member between said body and valve, and means controlled from a distance for moving the entire cylindroconical surface in one direction or the other. 2. Mechanism for controlling gas from a distance, comprising a casing, pipes attached thereto for the admission and escape a of gas, a cut-off valve, a spring to press the valve on'its seat, a freely and axially movable member having a conical surface of revolution between cylindrical portions of different diameters and co-aXial therewith,

" a ball between said member and valve, cylindrical bearings mounted on opposite sides of the cylindro-conical body and co-axial therewith, two electro-magnets adapted to be controlled from a distance by a source of a current, and cores attached to the cylindroconical body movable in said bearings.

3. Means for controlling the passage of gas'from a distance, comprising 'a casing, pipes attached thereto for the admission and 1- escape of gas, a cut-off valve, a body of revolution free to move, composed of a central conical part and two lateral cylindrical parts-of diiferent diameters, a freely'movable ball interposed between the body of revolution and the valve, an electro-magnet on each side of the body, andcores for said magnets mounted on the opposite faces of said body and co-axial therewith.

4. Means for controlling the passage of gas from a distance, comprising a casing, tubes on the casing for the admission and escape of gas, a valve, a seat for said valve, a freely movable'cylindro-conical body of revolution, a ball interposed between said body and the valve, a socket formed on'the tions, and means controlled from a distance to axially move said member to causethe ball to open the valve and permit it to close. In testimony that we claim the foregoing as our invention we have signed our names in presence of two subscribing witnesses.
