Application filedJanuary 21, 1910. Serial No. 539,347,
A My inventionrelates to electrically operated means for controlling the supply of gas to gas-burners, and also for igniting the same. Y
J According to my invention, my improved device comprises an electro-magnet which is provided with a hollow core 1 and with a double armature, the said armature being advantageously pivoted, or hinged, to the lower end of the electro-magnet, and being preferably composed ofone part inthe form of a fork, between the legs of which the second part, which is in the form of an elastically mounted hammer, is located. The upper end of the hollow core has mounted in it, but electrically insulated therefrom, a socket, or nozzle, through which the gas for ignition purposes escapes, and which is electrically connected to one end of the winding around the hollow core, the other end of the said winding being connected to a clamp-screw mounted upon, but insulated from, the lower end of the magnet core. A wire-or rod, of a non-oxidizable metal, extends through the socket, ornozzle, and is connected, at its lowerend, to the inside'of. I the hollow core, its upper end projecting through the open end of the socket or nozzle, and normally resting in contact therewith. m The hollow core is in communication with the casing of the valve controlling the supply of gas to the burner and to the bypass socket, or nozzle, and the connecting passage is provided with means, such as a spring-rod, by means of which the valve is controlled in the manner hereinafter described.
The device operates as follows, that is to pass passage in the magnet core and nozzle.
At the same time, the other part-of the double electro-magnet, that is to say' the,
elasticallymounted hammer, comes into contact w1th the spring-rod in the nozzle, presses the same back from contact withthe edge ofthe latter, thus breaking the electric circuit,isothat the said spring armature to make contact, whereby it is again attracted. In this manner, the. elastically mounted hammer is vibrated, and causes a series of sparks to be formed between the Figure 1 is ajsectional elevation of a de-- vice for controlling the supply of gas to gas burners and igniting the same, constructed according to my invention. Fig. 2
is a view similar to Fig. 1, but showing the parts in a different position. Fig. 3 is a face view of the double armature, and Figs. 4: and 5 are similar views, respectively, of the two parts thereof.
a represents the hollow core of the magnet, and b, c, the doublearmature thereof, 6
being the fork-shapedpartpivoted to the lower end of the hollow magnet core, 04 at 5 while 0 represents the hammer-portion,
which is mounted .upon the spring 0? secured to the lower end of the fork-shaped part b. e is the socket, or nozzle, which is fitted at the upper end of the magnet core a, the said nozzle-being insulated from the said core by means of the insulating sleeve cl.
f is the spring-rod of a suitable non-oxidizable metal, the said rod extending through the vnozzle e, and being secured at its lower end, as shown at 7, to the inner surface of the core of the hollow magnet a, while its upper end, which projects beyond the upper end of the nozzle 6, is normally in contact with the edge or lip of the latter, as clearly shown in Fig. 1.
g is the winding ofthe magnet, the upper end of the said winding being connected to the nozzle 6, while the lower end is connect- .60 I rebounds and again permits the spring-rod formed with a transverse passage 7', which is fitted with a bush 7c in communication with the interior of the casing Z, shown in broken lines in Figs. 1 and 2, of the valve which controls the supply of gas, to the service pipe of which it is fitted, the said bush is having mounted within it a rod m normally held in the inoperative position by means of the spring m and projecting, at its outer end, through the magnet a, and into contact with the lower end of the part b of the armature. Or the spring may be dispensed with, and the valve rod m be loosely connected to the armature Z), in which case directly the electric current is switched off the armature would be released from its contact f, and pull back the striker m with it, so permitting the ball valve m to return to its seat and close the gas supply.
The device operates as follows, that is to say: Assuming that the gas be cut off and that it be desired to ignite a burner, the electric circuit containing the electro-magnet is closed by a controlling switch (not shown) whereupon current flows from the battery, which is also not. shown in the drawings, to the binding screw it, thence through the winding 9, to the nozzle 6, and through the spring-rod f, to the hollow core a, and thence to earth. The double armature b, c, is thereby attracted toward the electromagnet, as shown in Fig. 2, this movement of the double armature actuating a the spring controlled rod m gfurnished with a valve m and a striker m so as to open the gas valve on, and cause the gas to pass through the same to the burner, and also through the hollow core a to the nozzle 6. The part c of the magnet is attracted simultaneously with the part b, and its upper end strikes the end of the spring-rod f, thereby pushing the same out of contact with the nozzle e, and breaking the circuit, so that the elastic armature 0 recoils, thereby permitting the circuit to be again completed, this operation continuing as long as the controlling switch is on, thereby causing the armature c to vibrate and create a rapid succession of makes and breaks and consequently a succession of sparks between the spring-rod f and the nozzle 6. This sparking ignites the gas issuing from the socket or nozzle e, and the ignited gas issuing from this by-pass serves to ignite the gas issuing from the main burner. It will be understood that the rapid make and break effected by the elastically mounted part 0 of the armature has no effect upon the part b of the armaturewhich controls the supply of gas by reason of hysteresis; that is to say, the vibratory movement of the part 0 resulting in the make and break, will not cause a corresponding movement of the part 6, since the latter, by reason of its greater mass, is held momentarily against the magnet core after each break by the action of hysteresis, the makes and breaks occurring in extremely rapid succession on account of the fact that the part 0 is attached to the spring 0 and hence is capable of vibration, and that said part coacts with the spring contact f, wherefore the part b will be held in retracted position during the entire time that the current is switched on, while the part 0 will be unaffected by hysteresis, owing to its relatively small mass and to its particular mounting above described.
