Application lec July 19, 1915. Serial No. 40,748.

To all whom t may concern j Be it known that l, l/VILLIAM LowMAN, a citizen of the United States, residing at Silver Creek, in the county of Merrick and State of Nebraska, have invented certain newv and useful Improvements in Gas-lgnit-- My invention relates to improvements in gas igniting systems, 4and more particularly `to those controlled electrically from points remote from the burners..

The object of the invention is to provide means of the class set forth which although being very simple and thus comparatively inexpensive, w1ll be highly efficient in operation and will possess a number of advantages.

With this general object in View, the ins vention resides in certain novel features of construction and in unique combinations of parts hereinafter fully described and claimed, and shown inthe drawings wherein:

Figure 1 is a diagram showing the improvedsystem; Figs. 2 and 3 are side elevations of portions of burners, showing the application thereto of one of the elements of the system; Fig. 4 is an enlarged vertical section through such element, and Figs. 5 and 6 are horizontal sections thereof as seen on the planes indicated by the lines 5--5 and 64-6 of Fig. 4. .l

In these drawings, (referring more particularly to Fig. 1) the numeral 1 indicates broadly a gas light of a common type to which gas is supplied by a pipe line 2, such line having therein an electrically opened and closed valve 3. Carried bythe burner 1, is a jump spark gas igniting device 4 which is shown in detail in Figs. 2 to 6 and will be hereinafter fully described.

`Disposed at a suitable point remote from theburner 1, 'is a plurality of batteries 5 shown in the present application as wired in series, while disposed adjacent said batteries is a jump spark coil 6. Connecting one terminal 7 of the primary coil 3 of said coil 6 with one terminal 9 ofthe batteries, is a wire 10, while leading from the other terminal of said primary coil is a wire 11 which is electrically connectedI with a switch tongue 12 normally spaced from butto be forced into contact with the platinum point or the like on an additional and parallel switch tongue 13. From the tongue 13, a wire 14 leads to the other terminal 15 of the batteries, whereby when the switch tongues 12 and 13 are brought into contact, the circuit of the primary coil 8 will be completed.

Leading from the terminal 7 to one terminal of the secondary coil 16 of the jump spark coil, is a shunt 17, while the induced current is led from said coil 16 through a wire 18, to` a third switch tongue 19 into contact with which a fourth tongue 20 is adapted to be brought upon .actuation of the tongue 12, an insulating block 21 being provided on said tongue 12 for contact with the tongue 2O to operate the latter. Leading from the tongue 20, is a wire 22 which is electrically connected with a Wire 23 carried by the device 4 and having its end bent toward the end of the pipe line 2 immedlately above the mantle or other type of Aburner proper with which the burner 1 is equipped.

When the switch tongues 12 and 13, and 19 and 20, are brought into contact, not only the primary circuit of' the coil 6 is completed, but the secondary current passes therefrom to the wire 23, such current then leaping the gap between said wire and the pipe 2 to form a spark, and finally returning to the batteries through the pipe line 2 and a wire 24 which is grounded thereto and is connected electrically with the. wire 14. Simultaneously with the' completion of the circuits for causing an electric spark adjacent 'the burner proper, the valve 3 is opened, said valve being wired as follows. Independent of the batteries 5, is an additional battery 25 from one terminal 26 of which a wire 27 leads to aswitch tongue'28 disposed parallel to but' spaced from the tongue 12, both of these tongues having their free ends curved inwardly and then outwardly as disclosed at 29 and receiving therebetween an insulating cone 30 on a stem 31, the latter having apush button 32.

lll@

to a magnet, solenoid or the like, with which the valve 3 is provided, such magnet, solenoid or the like, being in turn grounded by a wire 35 to the pipe 2, whereby .when the switch tongue 28 is forced toward the tongue 33, the current will flow from the terminal 26 of the battery 25, through the wire 27, through said switch tongues, and through the wire 34, to the valve 3, from this valve through the wire 35 to the pipe 2, from the latter through the wire 24 to the wire 14, and will then return from the latter to the other terminal 36 of the battery 25 through a branch wire 37. rlhe curw rent in so'traveling, opens the valve 3, and since the switches of the primary and secondary coils 8 and G are completed at the same time, an electric spark will jump across the gap between the wire 23 and pipe 2, thereby igniting the burner. Needless to say, in order to complete the circuits above described, it is simply necessary to depress the single push button 32, and when sufficient time has elapsed to allow the gas to be ignited, releasing of the button 32 will open the switches of the circuits including the jump spark coil, and will likewise break the circuit used to open the valve 3. rllhe latter, however, remains open until closed by electrical means now to be described. Spaced from the plunger3l is yan additional plunger 33 having a push button 3!) at its outer end and a cone 40 'at its inner end, such cone being formed of insulating material and. disposed in cont-act with the laterally bent end 4l of a switch tongiie42, whereby 'to force the latter toward an additional tongue 43. y Leading from 'the wire 27 to the tongue 43, is a current conducting wire 44, while continuing from the tongue 42 is an additional wire 45, the latter being so connected with the valve 3, as to cause the latter to be closed when the button 39 is operated and current flows from the battery 25 through the wire 27, switch tongues 42 and 43, and wire 45, to the valve 3 and from said valve through the pipe 2 and wires 24, 14., and 37, back to the battery. rlhus it will be evident that the burner may be extinguished at will from a remote point.

The preceding description refers primarily to Fig. 1 of the drawings, but the details of the igniting device 4 are shown more particularly in Figs. 2 to 6. In Fig. 2, a burner 46 is shown of the type commonly known as the Millanburner, such burners being provided with a substantially domeshaped co'ver plate 47 having at one side a horizontally disposed fiat surface which constitutes a seat 48, while at the center of this seat a circular opening is provided. Depending through this opening, is the lower end of the upright cylindrical body 49 of the device 4. The cylindrical body 49 is maaar@ provided with an annular outstanding shoulder 50 which is formed integrally with its intermediate -portion and which' is adapted rounding an appropriate'opening through' which the lower end of the body 49 projects. llhe body 49 is provided throughout its length with a cylindrical passage 51 whose upper end is enlarged as disclosed at 52 and receives therein a vtubular internally threadA ed binding post 53. Secured in any appropriate manner within the lower end of the post 52, is the upper end of the wire 23, the latter being extended from said binding post through the passage 51 and beyond the lower end of the body 49. The uninsulated end of the wire 22 is inserted into the upper end of the tubular binding post 53, and a wedge or the' like 54 is driven into said post to bind the wire therein as clearly disclosed in Fig. 4, after which a cap member 55 is correctly positioned upon the upper end of the body 49, to reliably insulate the exposed portions of the'wedge 54 and wire 22, said cap member including a head having therein a central opening through which the parts just mentioned project, and an annular flange which depends from said head and snugly surrounds the upper end of the body 49, such end being preferably though not necessarily increased in diameter.

By constructing the device 4 in the manner set forth in the preceding description, it will be evident that although its construction is very simple and inexpensive, its'operation will be ecient. Needless to say, the

projecting" lower end of the wire 23 may be bent laterally at numerous angles for accommodating the device to application upon burners of numerous types and if found necessary, said end may be totally or partially removed according to requirements.

. The foregoing description, when taken in connection with the accompanying drawings, is thought to be sufficient to familiarize those skilled in the art to which the invent-ion re lates, with the uses, advantages, and utility of the construction provided. Further description is therefore deemed superfluous. lt may be well, however, to add that although the system is shown and described for electrically igniting gas burners, it might well be applied to use in connection with burners using liquid fuel, and to more emphatically explain the functions of using switches in both the primary and secondary circuits and for using two batteries. rilhe first provision 1s made in order that any number of lights may be operated indeline for supplying fuel thereto, an electrically y dependent switches for the two circuits, and 1 a single push button for simultaneously closopened valve in said pipe line, and a jump spark device adjacent the burner; of an electric circuit including the jump spark device, a jump spark coil in said circuit, an additional circuit including the electrically opened valve, switch means for completing the two circuits, and a single manually operable member for closing said switch means at a single operation. j

2. The combination with a burner, a pipe linefor supplying fuel thereto, an electrically opened Valve in said pipe line, and a jump spark device adjacent the burner; of a source of current, a circuit including said source and the jump spark device, a jump sparl; coil likewise included in said circuit, an additionalsource of current, an additional circuit including said additional source and the electrically opened valve, in-

ing both switches.

3. An ignition device of the class described comprising an upright elongated one-piece cylindrical body having a rectilinear bore formed throughout its length, said bore having a cylindrical enlargement opening through the upper end of the body, a tubular internally threaded binding post received snugly in said enlargement and projecting above the body, a wire confined snugly in the bore and having its upper end secured in the lower end of the tubular binding post, the lower end of said wire being extended below the body, a current conducting wire received in the tubular internally threaded binding post and rising therefrom, a wedge driven downwardly in the binding post and forcing the wire into tight biting. engagement with the threads therein, said wedge having a lateral projection above the post to render it easily removable, and a tubular cap iitting over the upper end of the body and having an opening receiving therein the projecting upper ends of the binding post and wedge whereby to normally conceal them from view, said cap,l however, being slidable vertically from the body to render the wedge accessible for the purpose of removing the same.

In testimony whereof I have hereunto set my hand in' presence'of two subscribing witnesses.
