. DEVICE FOR LIGHTING GAs-LA Ps rn'oivr A DISTANCE.

To all whom it may concern; I ,p l Be t known that I, -LUDWIG SEvEnIN, a

subject of the; German: Emperor, residing at Hagen-Delstern, in theProv-ince of wVestph'alia, Prussia, Germany,have invented oer-1 tain new and useful Improvements in Devices; for Lighting GasLamps from a Distance,

\ of which the following is a specification; I

- The present invention relatesto those devices for lighting gas lamps from a distance,- 1n whlch the gas cock "is openedandclosedby means of an electromagnet, the circuit" of which is closed as theresult of memporary rise in pressure in"v the ,gas main. Known devices of thiskind are unsuitable for practicable purposes because,'owingto the gradual rise andfall of gas pressure,

, it may easily happen lthat, I during "the gradual approach and recession of the two contact-pieces, the following occursL; When-v these contact-pieces areloca ted 1n thejnn mediate vicinity of oneuanother, 1n conse-- quence' of small pressurevrvariations in the gas main or of mechanicalvibration result-1 ing-from' passing vehiclesyorthe like, contact is made for a number; of -times instead of only once as desired, and" consequently} the, gas cockyis actuated many times. 7 In order to avoid this, according to the present invention, an auxiliary switch is provided in circuit with the electromagnet, which switch, after each actuation of the gas [cock opens the circuit until the diaphragm has sunk sufficiently far, i. e-.\the contact pins have receded sufiiciently far from each other,.to exclude 'the possibility of uncle sired contact being made' It is thereby with certainty obtained that at each temporary rise and fall of pressure the gas cock is actuated only once and consequently the entire device works reliably.

One example of theapparatus according to the present invention is diagrammatically represented in the drawing, said apparatus being shown in its essential parts and in various positions of operation.

Figures 1, 2, 3 and 4 represent the apparatus in side elevation respectively in the normal position, the position of freeing the contact lever by the rising diaphragm, the position of closing circuit through the mag net which actuates the gas-cock, and the position of automatically opening such circuit again.

or lowered as-" stationary contact pin 1" and the contact lever t pivoted'at sl 'This'contact lever is p voted to rock in such inannerthat, by .virture Of its own 'friction, it tends to remainin any. position duringitsstroke. and" it i-s'rocked onewayor the other either by 'thedownwardly bent end u ofthe actuating lever h'orby the "bent arm o connected" to the diaphragm. I a I I Themode 'of operation of the device'is tollows Fig. l'as' before stated illustrates the devlcevln its normal position, 6. withnormal gas pressure and diaphragm in its lowest-position. I The contact device 0, 8,

is closed and the circuit is open at p g. When it is desired ,to light or extinguish the lamp by turning the gas cook, the pressure is increased in known manner in the main. Consequently the diaphragm 0 rises, the contact pin 9 approaches theplate p and the bent member '2) allows a free path for the contact lever s (of Fig. 2). When the I gas pressure has risento such an extent that the two contact pieces 29, q touch one another, the circuit of the electromagnet is immediately closed, and by means of the latter the actuating lever h (of Fig. 3) is attracted downwardly with simultaneous rotation of the gas cook. When the lever it moves downward its downwardly bent end it strikes against the rear' end of the contact lever t and consequently, as will be understood from Fig. 3, opens i the circuit of the electromagnet. The contact lever t tends, in virtue of its own friction, to remain in the slanting position, so that at this place the circuit is held open during the downward movement of the membrane, which movement starts only gradually. Any subsequent undesired contacts made by contact pieces 39 g are thus altogether without effect.

undesired contact between thecontact pieces 79, g is impossible, as the contactlever t of the auxiliary switch pulled down by the bentmemb'er v owing to the further movement of the diaphragm, this contact lever t 1 being thus returned to the normal position .1.1In apparatus-for lighting gas as shown in Fig. 1, and the auxiliarycontact device being in consequence again closed.

What Iclaim as my invention and desire to secure by Letters Patent is I from a distance, the combination with a valve for the gas, an electric circuit includinga pair of normally separated contact-' pieces, means for closing said contact pieces on a temporary rise in gas. pressure, and u I I l electromagnetic means, normally actuated by the closing of said contact piecesyfor opening or closing said valve, of means,1com prising a contact device adapted to be acted upon by said electromagnetic means, for

pieces means for closing said contact pieces on a temporary rise in gas pressure, and electromagnetic; means, normally actuated by the closing, of said contact'pieces, for opening or closing said valve, of means, comprising a contact device adapted to be acted upon by said electromagnetic means and Only when the diaphragm, as shown in Fig. 4:, has moved so far down that lamps connected in series with said contact pieces, for rendering said contact p eces, after closure, inoperative to close the circuit until .saidcontactpieces have again separated a predetermined distance.
