GAS LIGHTER.

Specification of Letters Patent.

Application filed September 19, 1908. Serial No. 453,847.

To all whom it may concern:

Be it known that 1, Wilson I). t). \Vnicu'r, a citizen of the- United States, and a resident of Germantown, Philadelphia, in the county of Philadelphia aml State of Pennsylvania, have invented a new and improved Gas- Lighter, of which the following is a full, clear, and exact description.

My invention relates to gas lighters, and has for its object to provide an electrical gas lighter which is constructed in the following manner. 7 v

A spark coil and battery cells are disposed in a casing, to which is attached a hollow standard, at the top of which there is a stationary electrode and also a spring electrode,

the latter being attached to an electrical conductive rod which is held in bearings in the hollow stem. A wire from-the spark coil leads to the stationary electrode in a plate in the casing which is insulated from the said casing. The casing is of conductive metal and the rod is in electrical.connnunication with the casing. 'l. he battery cells have contact plates at their terminals, which are adapted to complete the circuit between them and between the said plate in communication with the spark coil, and also with a spring which is in electrical communication with the metallic casing to complete the circuit with the rod.

In this specification I will describe thepreferred form of my inventiom'but I do not limit myself thereto as I consider myself entitled to all'forms and embodiments of the invention which may be held to fall within the scope of the appended claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which'similar characters of re terence indicate corresponding parts in all the figures, in which F'gure 1 is a sectional elevation of the invention; Fig. 2 is a sectional view on the line 22 of Fig. 1; and Fig. 3 is a sectional view on the line 33 of Fig. 1.

By referring to the drawings, it will be seen that a cylindrical casing 1 is provided, which has caps 2 and 3 which are adapted to screw on its terminals. In the casing 1 there is a partition 4 which is adapted to separate a spark coil 5 from battery cells 6. To the casing is secured a hollow standard 7, metallic brackets 8 being provided to hold the standard in place relatively to the easing. J ournaled in the standard 7 is an electrical conductive rod 9, which is in electrical communionlion with the casing, by means of its bearings, the hollow standard and the brackets, all of which are of conductive metal. At the top of the standard there is secured av member 10, which is preferably disposed at right angles to the standard, this member-l0 having a guard 11 disposed thcreovcr to protect the electrodes. One of these electrodes is stationary and is insulated from the member 10 by insulating material 12, the stationary electrode 13 being in electrical communication withthe spark coil 5 by means of an insulated wire 14. A spring electrode 15'is secured to the rod 9 and is so disposed that when the rod 9 is moved up and down, the spring electrode 15 will bring about a make-and-break contact with the stationary electrode 13. An upright stop 16 is disposed at one side of the spring elect-rode 15, this-stop being adapted to prevent the spring electrode 15 from moving out of operative position. Another wire 17' from the spark coil 5 passes through the partition 4: and is in conm'iunication with a contact plate 18. The partition 4 is of insulating material. in order to prevent a short circuit between the contact plate 18 and the casing. T he positive and negative poles of the battery cells (3 are eonnected by contact members 19, and an electrical communication is made between the lower battery cells 6 and the casing 1, by means of an electrical conductive spring 20. The hollow standard 7 is open at the bottom, and the electrical connective rod 9 projects through the opening, a spring 21 secured to the rod 9 pressing against the partition 22 to hold the rod down, and a lever 23 pivoted to an extension 2% of the hollow standard 7 is provided, to bear on the lower terminal of the rod 9 to press it upwardly.

In using my invent-ion,=the cap 3 is removed from the casing 1, and the batteries are then inserted in the casing in the usual manner, the connections between the battery cells being obtained by means of the cont-act members 19, the upper contact member being in communication with the contact plate 18, which completes the communication between the battery cells and the spark coil 5. The spring 20 is then inserted atthe bottom of the casing and the cap 3 is screwed in place. The lighter is then adapted to beused, and when brought in communication with-proper gas mixture, the rod 1) may be Patented Aug. 31, 1905).

ard, a stationary electrode secured moved upwardly by means of the lever 23, which will draw the movable spring electrode into contact with the stationary electrode 13, and when the lever is drawn away the spring 21 will draw the rod down, thus breaking the circuit and producing the de-.

sired spark.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

In a gas lighter, a casing in which are disposed a spark coil, anda battery, a standard, which is secured to the casing, an open frame secured to the top of the hollow standto the open frame having a substantially horizontal upper terminal, a rod journaled in the hollow standard, an electrode secured to the rod substantially at right angles thereto and being disposed trode, a stop, second elect-rode in the path of the first named electrode, means to hold the rod yieldingly downward," a lever having a shoulder, which is adapted to engage the lower terminal of the rod to move the rod upwardly, and an electrical circuit in which the spark, the coil, the battery, the electrodes,

and the rod form units.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
