JOSEPH C. LANDES. OF COLLEGEVILLE, PENNSYLVANIA.

AUTOMATIC GAS-LIGHTER.

To all whom it may concern:

Be it known that I, JOSEPH C. LANnEs, a citizen of the United States, residing at Collegeville, county of Montgomery, State of Pennsylvania, have invented a new and useful Automatic Gas-Lighter, of which the following is a specification.

My invention consists of an improvement in automatic gas lighters similar to the form shown in my Letters Patent No. 870,891, patented November 12th, 1907, the object being not only to seal the movable members within the top of the casing so as to prevent leakage of gas therein but also to automatically light the burner by the movement of the movable parts and to automatically extinguish the same.

Figure 1 represents a side elevation of a lighter embodying my invention: Fig. 2 represents a central vertical section thereof. Fig. 3 represents in elevation, the device for actuating the valve controlling the burner. Fig. i represents a sectional View of a portion of the igniter.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings. A designates the exterior casing of the device, the same being open at the top and practically closed at the bottom.

B designates the interior casing which is suitably'supported by the base C of the casing A and is open at the top and closed at the bottom excepting for the ports hereinafter designated.

D designates a rising and falling vessel or float which is closed at the top and open at the bottom, the sides of the said vessel being interposed in the space or chamber E be tween the side walls of the casings A and B.

In said space is placed a quantity of meronly as F, into which the vessel D dips and forms a seal for the bottom of the latter.

Connected with a suitable portion of the base C is a pipe G which supplies gas to the burner H.

Suitably fitted upon the pipe G is a rising and falling pipe J, which is suitably connected with the vessel G and to which pipe is secured the plate K, the latter carrying an arm L having a movable connection with the linkM which is also movably connected with the lever N, said lever being suitably mounted and having a spring actuated dog E suitably connected and adapted to engage upon upward movement, with a tooth Y Specification of Letters Patent.

Application filed February 23, 1907.

Patented Aug. 23, 1910.

Serial No. 358,765.

of the ratchet F, which is connected with the stem G. of the valve on the interior of the casing P, said valve controlling the flow of gas through the pipe G, it being understood that the valve is so arranged that upon upward movement of the pawl E and proper rotation of the stem G, it will permit the flow of gas through the pipe G to the burner and upon the next upward movement of the pawl E, it will actuate the valve to close the flow of gas to the burner.

Q designates an insulated block suitably supported on the casing A from which extends the rod R carrying one member of the contact device. Suitably connected with the plate K is the standard S which carries the other member T of the contact device and which is normally out of contact with the member carried-by the rod R, which latter is situated in the path of movement of the contact member T.

Carried by the standard S and insulated therefrom is the cage or shell H which is in suitable connection with the contact piece T and on the interior of which is a stem J,

-which is 'in suitable connection with the cage H, a filament or wire K being suitably connected with said stein J and also with a second stem L which is insulated from the cage H but is in contact with the standard S.

- U designates a battery having a conductor V in suitable connection with the rod R and a suitable conductor \/V in connection with the standard S.

Rising from the base C and surrounding the pipes G and J is a pipe X which is closed at the bottom and open at the top. In the space or chamber Y between the pipes G, J and X is a quantity of mercury Z in which the lower end of said' movable pipe J dips as a seal for the bottom thereof.

In the base C are the ports A and B-B, the same being in communication with the supply nipple C, the port A opening to the pipe'G and the port BB opening into the inner casing B.

The operation is as follows :It will be understood that the automatic gas controller is in suitable communication with the main gas supply and can be situated at any desired point. In order to light the burner, the gas pressure from the main is increased and the gas passing through the nipple C enters the pipe G and passes through the ports B entering the interior casing B and raises the vessel or float D. This carries with it the pipe J and elevates the plate K,

and in so doing, it carries with it the arm L, the link M and raises the lever N carrying with it the pawl E, which engaging with one of the teeth of the ratchet 1 rotates the same turning the stem G so that the valve is insuitable position for permitting the gas to flow through the pipe G, to the burner H, at the same time the standard S is elevated causing the contact piece 1 to contact with the piece carried on the rod R. This'closes the circuit in which the battery U is situated and the wire or filament it will glow, so that the gas will be ignited at the burner H, it being understood that the contact pieces will remain in contact while the pressure of the gas holds the same in position.

As soon as the burner is ignited, the pressure is suitably decreased and the float l) and the parts carried thereby are lowered, but the pawl E in lowering rides freely over the teeth of the ratchet F Without actuating the valve so that the gas continues to flow through the pipe G.

When it is desired to extinguish the gas, the pressure is again increased, raising the float D with the parts which it carries and causing the pawl E to again rotate the ratchet F and stem Gr carrying with it the valve controlling the supply of gas to the burner, which is thus closed, so that the light is extinguished and the pressure is decreased, the parts assuming their normal positions.

As the lower end of the vessel is situatedv in the mercury in the chamber E, the resultant seal prevents the gas that enters the easing B from escaping or leaking into the interior casing A and the seal resulting from the movable pipe dipping into the mercury Y prevents the gas that enters the casing D from escaping or leaking into the pipe J.

D designates a pipe tor filling the chambers E and Y with mercury, the same being in communication with the said chambers, so that by pouring mercury in said pipe it will be properly located in said chambers.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is
