Abstract
Abstract A manually operated gas lighter for use for lighting barbecues, fireplaces, camp fires, ovens, and the like, which once ignited can be maintained ignited by providing a locking member to positively maintain the valve actuator in its depressed position. The locking member circumscribes the lighter body so as to be relatively rotated with respect to the lighter body, and which circumscribing member is provided with a slot which is constructed to receive and lock the valve actuator in its igniting position by effecting a predetermined relative rotational movement between the lighter and the circumscribing member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
218 words
A gas lighter comprising: a lighter body having a reservoir portion for holding a supply of volatile liquid fuel, a normally closed valve for controlling the flow of gaseous fuel from said reservoir, a sparking ignition means disposed in igniting relationship with said normally closed valve, a valve actuator connected to said normally closed valve, means for pivotally mounting said valve actuator on said lighter body, said actuator having a portion extending beyond the periphery of said lighter body, means for positively maintaining and locking said valve actuator in the open valve position for maintaining said lighter ignited upon ignition, said latter means, including a member circumscribing said lighter body, said circumscribing member being mounted for rotation relative to said lighter body, and said circumscribing member having a slot formed therein for accommodating the extended portion of said valve actuator, said slot having a lateral offset leg portion for receiving said extended portion in the opened valve position upon effecting a predetermined relative rotation between said lighter body and said circumscribing member so as to positively lock said valve actuator in the open valve position for maintaining ignition, said lighter including a flame adjusting lever, and said circumscribing member includes a notched out portion for accommodating said adjusting lever, said notched out portion being disposed opposite said slot.
Claim 2
Dependent Claim
218 words

Claim 3
Dependent Claim
37 words
The invention as defined in claim 1 wherein said slot is "T" shaped with the stem of said "T" shaped slot being disposed in alignment with said valve actuator in the closed valve position of said actuator.
Claim 4
Dependent Claim
25 words
The invention as defined in claim 1 wherein said circumscribing member includes a ring rotatably mounted to said lighter body immediately adjacent said valve actuator.
Claim 5
Dependent Claim
104 words
The invention as defined in claim 1 wherein said circumscribing member includes an elongated tubular housing having an open end portion for accommodating said lighter body, said tubular housing includes a means for limiting the extent said lighter projects into said tubular housing, said slot includes a second lateral offset leg portion to define a "T" shaped slot wherein said opposed leg portions define the cross arm of said "T" shaped slot disposed in spaced relationship to the periphery of said open end of said housing, and said "T" shaped slot having a stem portion for receiving said extended portion of said valve actuator.
