In the casingare two electroshown in Fig. 5 as enlarged at this point, plays magnets, one controlling the admission of gas telescopically a'tube 29, having in its side to the igniter and the other controlling the wall a port 30. The tube 29 terminates beclosing of the valve which cuts off the supply low in a rod 31, having an eye, with which is 90 of gas to the burner. The gas is supplied to engaged the end of the pin 22, before men- 40 the burner through an upright pipe 1, havtioned. The metal plate 27 is insulated from ing a contracted mouth 2. The delivery end a frame 32, which forms a support for a short of the pipe 1 extends up into a chamber 3 in mica-protecting screen or chimney a nipple-base secured to a plate 4.. In the The current comes to the binding-posts 19 95 chamber 3 is a piston-valve 5, having in it and 20 through wires from the manipulator, gasapertures 6, Fig. 3, and provided with whereby the gas-burners are lighted and exguide-rods 7, which play through the plate tinguished. This manipulator is illustrated 4C. In the side wall ofthe chamber3 is a small in Figs. 6, 7, 8, and 9. This apparatus, as aperture which opens into a tube 9, secured here shown, is adapted for sending the cur- 103 to said wall and forming a chamber through rent into six igniting devices or into any or which extends an upright igniting-tube 10, all of them. This manipulator comprises a having in it a small port or opening 28 within case 35, the bottom of which, 36, is of wood the chamber in the tube 9. On the piston 5- 0r otherinsulating material. The case has a cover 37. Three cells 38, connected in series, are branched on wires leading to binding-posts 39 of the manipulator. These binding-posts extend to contact-knobs 10, and on the latter may be made to bear the free end of a switch-lever 4-1. By shitting said lever 4-1 to one or the other of the knobs 40 the current from one, two, or three cells of the battery can be caused to act in order to suitably supply one,two, three,or fouror even five or six of the igniting devices. The pivot-pin of the switch s1 is connected by a metal strip 42 to the arbor 43 of a pinion 44, provided with a switchlever 45. To effect ignition, the switch-lever 15 is brought over one of six contact-plates 46, which is connected to the binding-post 17, to which are attached the wires leading to the binding-post19 of the igniting device. The current is therefore sent into the igniting device which belongs to the particular plate 46 on which the switch lever 45 is pressed. The current from the battery flows from the latter to a binding-post 89, thence to a knob 40, thence to the switch-lever 11, thence to and through the strip 42, arbor a3, and pinion il to the switch-lever 45, thence to a plate 4:6, thence to a binding-post 47, thence to the binding-post 19 of the igniting apparatus. At this apparatus the current flows from the post 19 to the electromagnet 13 by a wire 48. The excitation of the magnet 13 attracts its armature 12, which in rising elevates the piston 5 and valve 11, thereby opening the mouth of the gas-supply pipe 1 and also the port leading from the chamber 3 to the tube 9. This permits the gas entering the chamber 3 to pass through the apertures 6 in the piston 5 to the burner and also to the tube 9, and thence to the igniter through the aperture 28 and tube 10. At the same time the pin 22 lifts the rod 31, and this latter lifts the tube 29, so as to put the port 30 therein into register with the port 28 in the tube 10, and this permits the gas to flow to the tube 10, as above stated. It may be noted here that in rising (see dotted linesinFig. 5) the piston 5 uncovers the port leading from the chamber 3 to the tube 9, the said piston and also the tube 29 actingas slide-valves. In rising the armature 12 elevates the strip 21, and thus establishes contact With the tip 23, so that the current flows from the post 19 to and through the strip 21 and tip 23 to the rod 24, thence through the platinum wire 25 to the pin 26, thence by the plate 27 to the tube 10, and thence returns, being grounded in the casing. This current heats the platinum wire hot enough to ignite the gas issuing from the upper end of the igniting tube 10, and this ignites the gas at the burner. It now the current be broken at the switch-lever 45 of the manipulator, the armature 12 of the magnet 13 will fall by gravity; but the armature will be arrested at the proper point in its descent by the rod 14 catching on the lug 15 on the spring-armature 16 of the magnet 17. This permits the piston 5 to descend far enough to close the port leading from the chamber 3 to the tube 9 without permitting the valve 11 to close the gas-supply pipe 1. At the same time the tube 29 descends in the tube 10 and closes the port 28 in the latter. Thus the supply of gas to the igniting-tube 10 is absolutely cut off.

To extinguish the ignited gas at the burner, the switch-lever-l5 is moved (toward the right in Fig. (3) so as to be put in contact with one of the contacts 19, which are connected with the binding-posts 50. The switch-lever 415 being depressed into contact with the contact t9, the current flows to the binding-post 20 of the igniting device at the burner and thence through the electromagnet 17. The armature 16 of this magnet is attracted and the supporting-lug 15 thereon is withdrawn from under the rod 1%. This permits the armature 12 to fall to the limit of its drop and the valve 11 to descend and cuts off the supply of gas to the burner.

In order to indicate to which igniting device the currentis being sent, either for igniting or extinguishing, the pinion 44-, connected to and turning with the switch-lever 15, is made to gear with a pinion 51, the arbor of which carries a hand which moves over a dial, as seen in Figs. 6 and 7. This is a simple form of visual indicator and will require no special description.

The manipulator is adapted for simultaneously igniting or extinguishing the gas at the three first, the three last, or all of the burners. To this end the binding-posts 47 are c011- nected electrically to six contacts 52, united in two groups of three each, and over each group is a spring-metal strip 53, which is connected by a transverse strip 54: with the conductor 42. Over each strip is a push-butten 55, and one of these buttons is pressedin order to close the circuit simultaneously through the first three or last three of the igniting devices. The third button 56 permits of pressing down a strip 57, which e11- gages the two buttons 55, so that both of the last-named buttons are depressed simultaneously and the circuit thus closed through the six igniting devices of the series.

For extinguishing the burners devices substantially the same as that just described and seen in Figs. 8 and 9 are employed. These are located at the right-hand side of the manipulator and will not, obviously, require particular description.

The valve 11 may be of lead, so as to be weighty enough to close the gas-supply pipe, and the piston 5 may be of anykind adapted to the purpose.

Having thus described my invention, I claim- In a gas-igniting device, the combination with an igniting-tube, of a cylindrical casing having a nipple at its top to receive the burner, an inlet at the bottom for gas to both the 1o ing a current of electricity through said magnet andthe igniting-wire simultaneously, sub stantially as set forth.

In Witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

VICTOR FORTI.
