ELECTRIC GAS-LIGHTING BURNER.

SPECIFICATION forming part of Letters Patent No. 243,344, dated June 21, 1881,

Application filed March 24, 1881. (No model.)

To all whom it may concern: I

Be it known that I, ADAM LI'JNGEN, of New York city, New York, have invented certain new and useful Improvements in Electric Gas- 5 Lighting Burners, of which the following is a specification.

As indicated by the title, my invention relates to that class of gas-burners which are placed in an electric circuit, with two elec- 1o trodes or terminalsof the circuit mounted on the burner and normally separate, but one of which is capable of being moved by the hand to close and break the circuit with the other, and thus produce an igniting-spark in the issuing gas. i

The electrodes in burners of this classhave been of various forms and arrangements relatively to the burner. In most cases one electrode is stationary and fixed close to the gasjet, so as to lie in the flame when the gas is ignited, and hence requires to be made of an expensive refractory metal, such as platinum. In a more recent burner both electrodes retire from the burner-jet out of range of the flame 2 when the gas is ignited. Now, in my invention the movable or operating electrode retires,

as usual, from the jet when the gas is ignited;

but the opposite or yielding electrode is so relatively arranged and constructed that it so always tends to lie against or closely approach the burner-tip, yet is always out of range of the flame when the gas is ignited.

In some burners of this class the movable electrode is operatively connected with the gas- 3 5 cock, so that the motion to produce the ignitingspark turns on the gas at the same time, while in most cases the gas-cock is operated separately by the hand, in the usual manner, and has no connection with the electrodes.

My invention has reference to burners of both these kinds.

The main requisites for an efficient electric gas-lighting burner, as will be readily appreciated, are that the electrodes make a pro- 5 longed moving contact with each other, and, finally, a sudden break as near as possible to or actually in the issuing jet of gas, so as to there deliver a strong igniting-spark, and thus light the gas with certainty at one action;

also, that the electrodes shall be out of the flame when the gas is ignited, so that they may be made ot'cheap metal; and,furthern1ore, that the back and forth movements of the electrodes to engage and disengage each other shall be smooth, easy, and certain, and not liable to entanglement or displacement; and, finally, that the general construction be simv ple, neat, and durable.

My invention aims to embody the abovenamed advantages; and it consists in a special form and arrangement of the electrodes and of the burner relatively to each other, as hereinafter fully set forth.

Figure l of the annexed drawings gives a side elevation of my improved burner with the electrodes in their quiescent position and the gas turned off. Fig. 2 is a similar elevation with the operating-electrode raised after having produced the igniting-spark, and showing the gas lighted. Fig. 3 is a sectional elevation, viewed from the reverse side of Fig. 2, with the gas shown turned full on and the electrodes shown just on the point of breaking contact to produce the igniting-spark. Fig. 4 is a plan view ofFig. 3. Fig. 5is a view similar to Fig. 4, showing the gas turned off and the operating-electrode in the opposite position and near the end of its return movement, where it disengages the yielding electrode. Fig. 6 is afrontelevation of the burner, viewed from the left of Fig. 1.

The burner ais cast in about the usualform, as illustrated, except that near the top thereof it is formed with a cross-partition, I), which divides the gas-inlet c at the bottom from the ti p-socket d at the top; The end 0 is threaded,

as usual, to SGI6W' upon the gas-pipes, and the end I) is ground to receive the usual lava tip, 6, which is cleft with the ordinary jet-slot,

as shown, but which tip serves the additional 0 purpose of an insulator in my burner, as hereinafter shown. The burner is formed with a lateral lug or boss, f, at the location of the partition b, which is bored with a conical hole or socket to receive a tight-fitting taper valve- 5 plug, 9, capable of rotary motion therein in the manner of an ordinary gas-cock, and from this socket, on either side of the partition I), ports h h extend, respectively, into the tip-socket and the hollow body of the burner, as illusroe trated in Figs. 8 and 5. A groove, i,isformed about two-thirds around the rotary valve-plug g at the location of the ports, so that when the plug is turned far enough in one position, as in Fig. 5, so that the solid part of the plug covers the upper port, communication between opposite sides of the partition is closed, and the gas is hence shutoff; but when rotated slightly in the opposite direction the gas is 10 turned full on, and so continues during even a large partial rotation of the plug, as seen in Fig. 8. Now, the valve-plugis thus moved by a lever, k, which is fixed thereto, as shown in the several figures, and this lever at the same time serves as one of the electrodes of the burner, one of its arms being fitted with a projecting pin, Z, which makes and breaks contact with the opposite electrode, m, while the other arm is provided with a pendent rod, a, by which the lever is pulled down to turn on the gas and produce the igniting-spark, or is pushed up to afterward turn off the gas and extinguish the light.

One pole of the battery, usually the posi- 2 5 tive, is connected to the gas-pipes, with which the burneris, of course,in metallic connection, and the lever 7c hence forms the positive electrode in being in metallic connection with the burner. The negative wire from the battery 0 accordingly connects to the other electrode, m, as shown, which is, of course, insulated from the burnersay by a block of insulating material screwed or swaged into a hollow boss on the side of theburner and held in an ordinary 5 simple manner, as clearly illustrated in the several figures.

The electrode m n ay be called the yielding electrode, as it yields to the movement of the rigid electrode 70 l, and, as may be observed, 0 is formed and acts as a plate-spring, being made preferably of sheet-brassor German silver, and of a good width and thickness, as illustrated, so that strength and durability are obtained. The lower end of this spring-elec- 5 trode m is fixed to the insulator, as shown,

while the upper end curves toward and normally rests with a slight elastic pressure against the lava tip 0, preferably in the groove below the slotted head thereof, as shown,

against which it constantly tends to spring, as illustrated in Figs. 1, 2, 5, and 6, and it will be readily seen that as lava is an insulator, hence the circuit is not closed by this contact, while the spring is by this means supported at its free end, and has thus greater stability.

It will be readily noted from the several figures of the drawings that the axis of the electrode-lever 7c is arranged at such position and the electrode-pin l at such radius relatively to the spring-electrode m that the are through which the pin moves intersects the spring at a slight distance from its tip. Now, it will be seen on reference to Figs. 5 and 6 that at this part the spring is cleft by a cut, so as to form a secondary spring tongue or pawl, m,

pointing downward, and that during the downward or return movement of the lever g, as shown in Fig. 5, the electrode-pin Z contacts with said tongue, presses it inward, and finally rides overits tip, and passes behind the spring into the position shown in Figs. 1 and 6, the limit of its motion being determined by the arm of the lever striking one side of the stop 0 on the burner, as seen in Fig. 1.

It will be readily understood from Figs. 5, 6, and 1 that in the position of parts just described the gas is shut off, the electrodes are out of contact, and the circuit broken, the parts being hence quiescent. When,however, it is desired to light the gas, the rod a is pulled down, which of course swings the lever around, and the first part of its motion at once turns on the gas, as will be understood from Figs. 3 and 5, and at the same instant brings the pin Z into contact with the spring m m, thus closing the circuit. The pin now continues a rubbing contact with the spring on the inner curved side thereof till it arrives at its tip, as seen in Fig. 3, when the spring rides off, thus breaking contact, and hence emitting a strong spark in the issuing gas-jet, which ignites the same, as shown in Fig. 2, the lever being thence moved to the limit of its up motion, which is determined by a shoulder on its opposite arm striking the opposite side of the stop 0, as in Fig. 2.

It may be noted that the lever is held in either its up or down positions by the tension of a spring, 1), which connects to a crank-pin at a short distance from its center, and which, passing over the center, on either side of its swing, holds the lever reliably in either of the positions in which it may be set.

The merits of the described construction and arrangements of parts may be now appreciated when it is noted, first, that by this means the gas is turned on well in advance of the igniting-spark, so that the dead gas or air, always present to some extent in the outer parts of the pipes, has thus free chance to escape before the advance of the rich gas, which issues in its fullness by the time the igniting spark is produced, so that the lighting of the gas is thus rendered more certain; second,

the gas-cock is arranged so close to the tip of v the burner that the air which has to be driven out before the gas is reduced to the smallest possible quantity, and thus contributes to the result above stated. Furthermore, the relative form and position of the spring-electrode m is such that it is nearly tangential to the are, through which the contact-pin l moves, (see Figs. 1 and 3,) which possesses two advantages: First, it insures a prolonged rubbin g contact of the electrodes, and thereby keeps the circuit closed long enough to charge the circuit up to a high tension, so that when the break finally occurs, as in Fig. 3, the full reaction insures a vigorous spark for the certain ignition of the gas; second, the mechanical advantages thus given to the lever over the pressure and friction of the spring m on the pin Z enables the spring to be made strong and to press with considerable friction on the pin, so as to keep the contact-surfaces bright and clean, in a condition for perfect electrical action, yet the frictional resistance thereof becomes hardly perceptible to the hand in operating the lever. Moreover, it may be noted from the several figures that the jet-slot in the burner-tipis placed diagonal to the are through which the pint moves, that the end of the yielding electrode m, when quiescent, rests against the tip just below the jet-slot, and that the pin, in breaking contact therewith, takes an upward course and rises over the tip and through the edge of the gas-jet, and thus emits the igniting-spark directly into the jet, which renders its ignition sure; but after the ignition occurs, as in Fig. 1, it will be seen that both electrodes are removed from the flame, the electrode m, which never enters the jet, resting against the lava tip 0, below the flame, where the heat is never injurious thereto, while the lever and pin k l retire to a lateral distance from the flame, as shown best by dotted lines in Fig. 4. Hence both electrodes maybe made of brass or German silver instead of platinum, as would be otherwise necessary.

In addition to these advantages, it may be observed that the engaging and disengaging motions of the electrodes are smooth and easy, and such as not to render them liable to entanglemeut or displacement in their back and forth motions.

It will he therefore observed from the above recapitulation that my burner embodies all the desirableadvantages before referred to, and constitutes a material improvement in this line.

In the drawings I have shown the operatingelectrode as operatively connected with the gas-cock and the gas-cock or valve embodied in the burner; but in most cases an ordinary valveless burner will be used, with the operatin g-electrode simply pivoted thereon, the val ve plug g, ports h h, and partition I) being dispensed with and the gas turned on or off by the operation of a separate stopcock in the usual way. In this case, also, the lever-electrode will he so acted on-by its spring as to always tend to return to the position shown in Fig. 1 after the gas is lighted. The construction in other respects will, however, be substantially the same as illustrated.
