ERNEST H. -STUBTS, PHILADELPHIA, PENNSYLVANIA.

- eas-LIGHTER.

Be it known that I, lihinas'r/y H. STu-R'rs, a

Philadelphia, in'thecounty of Philadelphia and State of Pennsylvania, have 4invented certain new and .useful Improvements' in Gas-Lighters, of which v.the following is a specification.

My invention relates to improvements in gas lighters, the object ofthe invention being to provide improved means for turning on and off the gas'supply from a burner,y and at,the same' time automatically controlling the operation of the pilot light, so that .when the gas is turned onthe pilot light will be permitted' a supply` of gas suflicient' to insure the lighting of the burner, Whereas pilot light is 'maintained low. A u Y A'further object is to provide improvements of the character stated which areespecially adapted for use in connection with olf the gas when the temperature of the Water' reaches a pre-determined degree.

A`further object is to provide' improvements of the character stated whichv are operated electrically from a distance, andA .which is of-extremely simple construction, strong and durable'in use.

" With these and other objects in'. View,v the invention consistsin certain novel features of construction and combinations "and arrangements of ,partsaswill be more fully hereinafter described and pointed out '1n accompanying drawings: Figure 1 1s a view partly in elevation and partly in section illustrating myvimprovements.

3 is a gas burner having a central opening 1 therein, and supported atthe upper end of a gas supply pipe 5, `the latter located at one "side of the center ofthe burner, and at its lower endiiared outwardly as shown at 6 so as to' provide ample space for the entrance of air. In other words, the burner above described is of thel vordinary Bunsen type, and is connected to a lgras supply pipe by means of an electro-magnet inclosing casing 8, and a cock 9. 1n the casing 8, a central vertical pipe 10 having -a turning plug' 11 therein is located, and at the ends of 5said pipe 6, disks l2 and 13 respectively Specification of Letters Patent. Patent-.Qd Sept, 21 1915 Application slee october'ar, 1914. serial un. 868,833.

are secured,'and over which casing 8 is posiedge as shown at 15, and into which recess a pin 1 6 is projected to limit the turning vmovement of the plug. The segmental disk 14 is engaged by two

pivoted armatures

17 and 18 respectively. I

The armatures 17 and v18 have parallel lugs 19 projecting therefrom at their centers and located at opposite sides or' hangers 20 depending .from the upper disk 12. Manually perated pulls 21 project through the upper disk 12, andY are connected to in- Igers 19 of the ,respective armatures to per-` mit the armatures to be moved and the gas .to be manually turned on and oli" as occasion' may require.

The

armatures

17 and 1,8 are located above electro-magnets Land 0 respectively, .the former causing the gas to be'turned on to light the burner, and the latter causing the.

,das to be turned off to extinguish the burner. It will be noted that the movement yof one armature compels the. reverse movement of the other, and these parts are of such a construction that when once moved they Will remain in thepositionlmovedzuntil -therotheiffinagl'iet is energized to reverse the positions. f

22 represents a relatively small gas' tube communicating with the pipev 10 below the turning` plug 11. The tube122 extends up beside pipe 5, and at its upper end is provided with a chimney 23 in which a small of gas being permitted to pass through a' groove 27.

The valve Q6 1s normally held on its seat 4by a spring 28, and when the valve is opened,

a relatively large amount of gas is supplied to the pilot to allow the same to burn above the chimney as will be hereinafter explained.

The lower end of the stern is positioned above a head on the upper end ot' a vertically movable rod 2t). rlhe lower end of this rod 29 is positioned above a pivoted armature 31 controlled by an electro-magnet P, so that when the magnet .l is energized, the armature 31 will compel the valve 26 to open, and allow a sutlicient amount ot' gas to How through the tube '.22 to project the tlame ot' the pilotabove the chimney 23 and through the openingr fl. in the burner 3, causing the burner to be lighted.

To insure a spreading ot the flame and the proper lighting of the burner, a V- shapcd del'lecting bar 32 is positioned across the opening 4 and serves to deflect the liame to both sides in position' to ignite the gas es :aping through'the orilices ot' the burner.

The boiler 1 is equipped with a thermostat which may be made in any approved Jform, but in the present instance consists of a tube inclosing a rod S4, the tube and rod being of different metals, so that the expansion of the tube causes the longitudinal movement ol the rod. The outer end of the rod is connected to a lever the latter pivotally supported on a bracket 31S, The lever 35 carries at its free end, a Contact 37 normally spaced froma contact 38, the latter insulated from the boiler.

On the upper disk 12, I locatea support 19 carrying a contact 10 insulated theretrom. On one of the manually7 operated pulls 21, I locate a contact 41 which engages the contact 110 when the armature 17 is in position to turn on the gas, and these contacts are apart when the armature 17 is elevated by reason of the downward movement of armature 18 to shut oii' the gas.

In Fig. 8, I illustrate an electric diagram showing one means for electrically controlling the several parts. L and O represent electric switches which preferably comprise spring-pressed buttons, so that when the buttons are pressed, the circuit will be closed, and when released, the circuit will be opened. B represents a battery or source of electricity supply which is connectedv in circuit with the several electro-magnets and contacts as will now be explained. From one side of the battery B, a wire 4Q extends to the switches B and L. A wire 43 connects switch L with electro-magnet L, which latter is connected to electro-magnet l by a wire 111, and the latter is connected to the opposite side of the battery by a wire lo. Switch U is connected by a wire lo with the electro-magnet O, and the latter is connected by a wire 17 with wire 15. 1S is a wire connecting the contact 3T with the wire L12, and L19 is a wire connecting contact 3% with contact 10, contact -11 being connected by ar wire 5U with wire L16.

When the switch L is operated, the circuit is as follows: from battery B, through wire 42, switch L', wire 13, electro-magnet L, wire 4l, electro-magnet I), and wire 45 back to the battery. This causes thc gas to be turned on and the pilot light to flare up sutlicient to light the burner. It .is to be miderstood that assoon as the circuit above described is broken, the valve of the pilot light returns to closed position, so that the pilot assumes its normally small llame. Ille energizing ot electro-magnet li moves the contact 4l against the contact ll). lv'hen it is desired to turn oti' the gas supply to the burner. switch O is operated. The electric circuit is then from battery B, through wire #12. switch wire 46, electro-magnet wire 1T. and wire 45 back to the battery. If the switch O is not operated to cut oil the supplyv ot' gas, and the temperature ot' the water inthe boiler reaches a pre-determined degree, the operation ot the thermostat 3?, will cause the contact 37 to move against contact 3S, and close the electric circuit to the magnet O as followst-t'rom battery ll,

through wire 4Q, wire-i5, contact l'T. contact i 3S, wire 4S). contact -l-i).y contact ll. wire 50. and wire lo to' elet-trimagnet and vfrom thc latter through wire -lT and wire l5 to the battery. The electro-magnet O will then turn oil' the gas, and in doing s0 willh compel the armatures 17 and 1S to reverse their former positions. The movement of armature 17 will instantly separate the contacts 4() and 4l, so that there will be no drain upon the battery. lt will therefore be noted that the contacts and l1 are together only when the gas is turned on, and at such times the contacts 37 and are apart, so that there is no drain upon the battery at any time. j

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I. do not limit myself to the precise details set forth, butoonsider myself at liberty to make such chan es and alterations as fairly i'all within tie spirit and scope of the appeudedclaims.
