CIGARETTE LIGHTER WITH TIME LOCK
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.

Description
BACKGROUND OF THE INVENTION
This invention relates to cigarette lighters and also to devices
for discouraging smoking.
DESCRIPTION OF THE PRIOR ART
As the health hazards attendant upon cigarette smoking have been
publicized with great energy of late by a number of concerned
individuals and groups, the numbers of substances, processes and
devices for helping individuals to quit smoking have greatly
multiplied.
Many of these substances, processes and devices attempt to
transform a heavy smoker almost instantaneously into a non-smoker
and this abrupt change in life-style often proves so unsettling to
the smoker that he quickly returns to a full habit. It is
obviously, desirable therefore to provide an efficient means for
weaning smokers away from their habit, i.e., for gradually reducing
the smoker's consumption of cigarettes per unit of time. In this
manner the chances of partial, if not complete, rehabilitation
should be greatly enhanced.
SUMMARY OF THE INVENTION
The applicant's invention concerns a device which enables a smoker
to gradually lengthen the time between his smokes and thereby
reduce his habit. Furthermore, within the psychological limits of
the smoker's desire, the applicant's device acts to ensure that the
smoker cannot cheat himself by smoking within the intervals he has
set for himself.
The applicant's device comprises, essentially, a time lock which is
operably connected to and incorporated within an otherwise
conventional cigarette lighter for rendering the lighter inoperable
for the time set on the time lock and means which is adjustable by
the operator of the cigarette lighter for setting the timing of the
time lock. The applicant's invention also includes a counter with a
visual indicator which is connected to the time lock for displaying
the number of times the time lock has been set and thus,
indirectly, the number of times the cigarette lighter has been used
(providing, of course, that the time lock has been energized prior
to each use of the cigarette lighter).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiments of the invention will now be described
with reference to the drawings in which the same elements are
identified by the same reference numerals.
In FIG. 1, reference numeral 10 refers to a conventional cigarette
lighter of the type in which a digital depression of the flint
striker lever 12 about pivot 13 causes the cover 14 to be removed
from the wick (not shown) and, simultaneously, causes a flint
disposed adjacent to the wick to be struck thus igniting the fuel
absorbed within the wick. Thus, it is possible to deactivate the
lighter 10 by restraining the depression of lever 12 which may be
restrained by the following mechanism: Depending from the lever 12
is a locking rod 16 one end of which abuts a shoulder 18 on the
underside of lever 12. The rod 16 is guided by bushing 20 and urged
upwardly to the position shown in FIG. 1 by spring 22. When the
timer locking gear 24 is in the position shown in FIG. 1 the lower
end of rod 16 registers with the locking gear slot 26 which is
formed in the periphery of gear 24 and adapted to receive the lower
end of rod 16. Thus, in this position, the lever 12 may be
depressed since slot 26 is deep enough that lower end of rod 16
will not abut against any surface during the travel of lever
12.
When a smoker desires to inactivate the lighter 10 he merely
manipulates the thumbwheel 28 which has a toothed circumference 30
which meshes at a point of contact with the teeth 32 on the
circumference of the time locking gear 24. This, of course, causes
gear 24 to rotate so that the lower end of rod 16 now faces a
section of teeth 32 rather than slot 26, and attempts to depress
the lever 12 are restrained by contact between rod 16 and teeth
32.
The rotation of gear 24 also energizes a standard time mechanism 34
which may be conventionally powered by a battery or a spring. If
the power source is a spring, it may be rewound by the rotation of
gear 24 through thumbwheel gear 28 and if the power source is a
battery, the rotation of gear 24 may close a switch to connect a
motor (not shown) to the battery (not shown).
The timer mechanism 34 which is a best seen in FIG. 2, connected to
gear 24 at its axle 25 then causes the gear 24 to rotate until the
slot 26 is again in registry with rod 16 and the lighter 10 is thus
again capable of operation.
The amount of time during which the lighter is deactivated is
indicated by a timer scale and pointer 36 and 38, respectively,
shown in FIG. 3, said pointer 38 being mechanically connected to
timer mechanism 34. The scale and pointer can be seen from without
the casing 11 of the lighter 10 through crystal 40. In the
embodiment described above, timer mechanism 34 is adjustable to
settings between 1 and 60 minutes and thus the scale 36 indicates
this range of settings.
Turning now to the second embodiment with special reference to FIG.
4 through 6, it is seen that the lighter 10' shown therein is of
the type construction in which a lid 42 is pivotally connected to
the body 44 of the lighter at pivot point 43. The lid 42 must be
pivoted away from the position shown in FIG. 4 in order to expose
the wick and flint assembly and thus it is possible to deactivate
lighter 10' by locking lid 42 to body 44.
As can best be seen in FIGS. 5 and 6 the lid 42 has a tab 46 which
projects in a substantially perpendicular manner from one interior
wall.
When the lid locking gear 48 is in the position shown in the FIGS.
4 through 6, the tab 46 can pass through the slot 50 formed in the
flange 52 which is annularly disposed about the periphery of the
lid locking gear 48. When the locking gear 48 is rotated from the
position shown, the flange 52 is interposed above the tab 46 and
thus the lid 42 cannot be removed from the body 44.
The locking gear 48 can be rotated by manipulation of the reset
knob 54 since this knob is connected to the free end of axle 56
about which the locking gear 48 rotates. The axle 56 is mounted for
rotational movement in a bushing 55 which forms a portion of a side
wall of the cigarette lighter body 44.
Rotation of the locking gear 48 also causes rotation of the timer
output gear 58 since the gear 48 has a toothed periphery which
intermeshes with the toothed periphery of the timer output gear 58.
The rotation of gear 58 is transmitted to the timer mechanism 34 by
means of shaft 60 about which the gear 58 is mounted for rotation.
The timer mechanism 34 is identical to the timer mechanism
discussed with respect to the first embodiment in construction and
operation and thus, it is energized by the input from axle 60 in
the manner discussed above.
When energized the timer mechanism 34 causes the gear 58 to drive
the gear 48 until the slot 50 is again aligned with the tab 46 and
thus the lid 42 may be tilted back from the body 44 of the
cigarette lighter 10. The amount of time during which the lid 42
will be locked to the body 44 is indicated by the time scale 36 and
pointer 38 through the crystal 40, all of which are identical to
elements with the same reference numerals discussed above.
Turning now to FIGS. 7 and 8 a third preferred embodiment will be
described which can be utilized with any conventional type of
lighter but which is shown for convenience in the type lighter
having a hinged lid.
In the third embodiment a flint striker wheel 62 having
peripherally disposed serrated edge 64 is rotatably mounted upon
the windguard 66 of a lighter adjacent to the wick 68 thereof.
A flint 70 is urged into contact with the serrated edge 64 by a
spring 72 which bears against a plate 74 and is restrained and
guided within the tubing 76 such that rotation of the wheel 62
strikes a spark against the flint 70 in a conventional manner.
Since the plate 74 bears against the lever 78 which is pivoted for
rotational movement about point 80, the compression upon spring 74
and thus the force with which flint 70 contacts edge 64 may be
varied by rotating lever 78.
The lever 78 is urged in clockwise direction (as viewed in FIG. 7)
by tension spring 81 which is fixed to the lever at one end and to
the casing of the cigarette lighter at its other end.
Simultaneously, however, the lever 68 can be urged in the
counterclockwise direction by the cam follower 82 which is urged
against the periphery of the timer cam wheel 86.
In the position shown in FIG. 7 the cam follower 82 is received
within the slot 90 within the timer can wheel 86 and thus the force
of spring 81 is essentially unopposed so that the lever 78 is
rotated to the position shown. In this position a maximum
compression is exerted upon spring 72 and thus flint 70 is strongly
forced against serrated edge 64.
When the timer cam wheel 86 is rotated in a counterclockwise
direction the cam follower 82 engages the circular portion of cam
wheel 86 which engages cam follower 82 and thus causes lever 78 to
pivot about point 80, and thus the force of spring 81 is overcome
and the lever 78 is urged to the position shown in dotted lines. In
this latter position the compression upon spring 72 is relieved and
thus the flint 70 is not pressed against the serrated edge 64,
i.e., the lighter is deactivated.
The timer cam wheel 86 can be activated by a reset knob 54
identical in construction to the knob 54 used in the second
embodiment and the timer can wheel 86 can be driven by a timer
mechanism 34 such as is described in either of the prior
embodiments.
Similarly the amount of time during which the lighter is made
inoperable can be indicated by a time scale 36, a pointer 38 and a
crystal as described above.
A counter may be associated with the pointer 36 and time scale 38
of any of the preceding embodiments to provide an indication of the
number of cigarettes smoked. Such a counter, as illustrated in
FIGS. 9 and 10 may comprises a gear 92 which is mounted upon the
shaft 37 which connects the pointer 38 to the time mechanism 34.
The gear 92 is connected to shaft 37 by a one way drive clutch 94
so that when the pointer 38 is rotated counterclockwise, one
increment for example, one minute, as shown in FIG. 8, the gear 92
is rotated clockwise one increment. A continued rotation of shaft
37 will not, however, be passed by spring clutch 94 to gear 92 and
thus even if the pointer is moved from the zero to the 60 minute
mark the gear 92 will be indexed only a single increment. The
toothed periphery of the gear 92 is in contact with the toothed
periphery of an indicator wheel 96 so that the indicator wheel is
indexed in the opposite direction for any indexing of the gear 92.
The indicator wheel 92 has the numbers of an arithmetic progression
starting with the number one formed thereon in an annular region
near the periphery of the wheel to indicate the number of times the
timer has been set and thus, indirectly, the number of times the
lighter has been used.
The numbers on the indicator wheel may be visible through the
crystal 40 discussed above or through a separate window in the
lighter's casing.
While the above description fully covers the preferred embodiment
of the applicant's invention, many modifications to the invention
are within the scope of the invention, thus for the full scope of
the invention reference should be made to the following claims.
