Abstract
Abstract A time lock associated with a cigarette lighter can be set to deactivate the lighter for the set time. The time lock may be mechanically or electrically powered or powered by a combination of those forces. The time lock may operate to lock the cover of a first type lighter to the body thereof, it may prevent the depression of the flint striker lever in a second type lighter or it may, in either type of lighter, remove the compression force between the flint and the striker wheel. A counter may be associated with the time of the time lock to register the number of times the time lock is set and thus, indirectly the number of times the lighter was used.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
60 words
In a mechanical cigarette lighter of the type requiring the operation of a mechanism precedent to the ignition of a spark, the improvement comprising means contained within and cooperating with said lighter for restraining the operation of said mechanism, a timing mechanism connected to and controlling said restraining means and a setting means connected to and controlling and timing mechanism.
Claim 2
Dependent Claim
60 words
In a mechanical cigarette lighter of the type requiring the operation of a mechanism precedent to the ignition of a spark, the improvement comprising means contained within and cooperating with said lighter for restraining the operation of said mechanism, a timing mechanism connected to and controlling said restraining means and a setting means connected to and controlling and timing mechanism.
Claim 3
Dependent Claim
116 words
The cigarette lighter as recited in claim 1 wherein said mechanism comprises a flint striker lever and said restraining means comprises a rod means abutting said flint striker lever at one end and, at its other end, abutting the periphery of a wheel including a radially directed aperture on the periphery of a wheel being connected to said timing mechanism, for rotation about its axis in response thereto so that the movement of said flint striker lever is restrained when said rod means abuts the periphery of said wheel when said wheel is in a first position but is not restrained when the peripheral aperture of said wheel is rotated into register with said rod means.
Claim 4
Dependent Claim
119 words
The cigarette lighter as recited in claim 1 wherein said mechanism comprises a hinged lid covering the fire producing portion of said lighter and said restraining means comprises a tab projecting from an interior wall of said lid and a wheel disposed adjacent said tab and including a peripheral flange having a slot therein, said wheel being connected to said timing mechanism for rotation about its axis in response thereto so that said tab is locked within said flange and thus said lid is locked over said time producing portion when said wheel is in a first position wherein said flange overlaps said flange but said tab is unlocked when said slot is rotated into register with said tab.
Claim 5
Dependent Claim
58 words
The cigaretee lighter as recited in claim 1 wherein said mechanism comprises a spring for compressing a flint against a flint striker means, a plate against which said spring bears and said restraining means comprises a lever bearing against said plate and means for adjusting the position of said lever for thereby relieving the compression upon said spring.
Claim 6
Dependent Claim
51 words
The cigarette lighter as recited in claim 4 wherein said adjusting means comprises a wheel having a cam surface on its periphery which is mounted for rotation, a timer for rotating said wheel, a cam follower connected to said lever and means for urging said cam follower against said cam surface.
Claim 7
Dependent Claim
24 words
The cigarette lighter as recited in clAim 1 further including means for indicating the setting applied to said timing mechanism by said setting means.
Claim 8
Dependent Claim
36 words
The cigarette lighter as recited in claim 6 further including means associated with said indicating means for counting the number of times said setting means are utilized and for displaying a cumulative count of said number.
