Abstract
Abstract A mechanism for shielding a cartridge containing a pyrophoric substance in which the cartridge is encapsulated and is placed on an ignition device such as a cigarette lighter. The encapsulated cartridge cannot discharge its flammable contents until it is placed within the confines of the ignition mechanism, thereby rendering the cartridge safe to handle when it si removed from the ignition mechanism.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
105 words
An encapsulated cartridge for use with a combustion device comprising: a. a housing having a first opening therein; b. means on the housing or removably attaching the housing to the combustion device; c. a cartridge mounted within the housing; i. the cartridge having an outlet nozzle and containing a pyrophoric substance therein; ii means on said cartridge for ejecting the pyrophoric substance therefrom; d. means for aligning the nozzle on the cartridge with the opening in the housing in response to the location of the housing with respect to the combustion device so as to prevent inadvertent ejection of the pyrophoric substance from the nozzle.
Claim 2
Dependent Claim
105 words
An encapsulated cartridge for use with a combustion device comprising: a. a housing having a first opening therein; b. means on the housing or removably attaching the housing to the combustion device; c. a cartridge mounted within the housing; i. the cartridge having an outlet nozzle and containing a pyrophoric substance therein; ii means on said cartridge for ejecting the pyrophoric substance therefrom; d. means for aligning the nozzle on the cartridge with the opening in the housing in response to the location of the housing with respect to the combustion device so as to prevent inadvertent ejection of the pyrophoric substance from the nozzle.
Claim 3
Dependent Claim
33 words
An encapsulated cartridge as defined in claim 1 in which the housing has means thereon for masking the outlet nozzle of the cartridge when the cartridge is not mounted on the combustion device.
Claim 4
Dependent Claim
25 words
An encapsulated cartridge as defined in claim 2 in which the combustion device has means thereon to remove the means for masking the outlet nozzle.
Claim 5
Dependent Claim
17 words
An encapsulated cartridge as defined in clam 1 in which said housing comprises walls surrounding the cartridge.
Claim 6
Dependent Claim
17 words
An encapsulated cartridge as defined in clam 1 in which said housing comprises walls surrounding the cartridge.
Claim 7
Dependent Claim
42 words
An encapsulated cartridge as defined in claim 1 in which said cartridge has a boss thereon connected to the outlet nozzle, and hammer means adjacent said boss whereby the hammer means actuates the boss so as to eject the pyrophoric substance therefrom.
Claim 8
Dependent Claim
40 words
An encapsulated cartridge as defined in claim 5 in which the combustion device has a fingerpiece thereon and a burner valve, means responsive to the actuation of the fingerpiece whereby the valve is operated and the hammer means is actuated.
Claim 9
Dependent Claim
63 words
An encapsulated cartridge as defined in claim 5 in which said hammer means comprises a lever pivoted at one end thereof, first spring mans urging the lever to rotate about the pivot and a cam surface on the lever against which the spring means slips, a second spring means which rotates the lever when the first spring means slips off the cam surface.
Claim 10
Dependent Claim
36 words
An encapsulated cartridge as defined in claim 1 in which the housing has resilient means fixed thereto which bears against the cartridge and maintains the cartridge in a position spaced from the opening in the housing.
Claim 11
Dependent Claim
41 words
An encapsulated cartridge as defined in claim 1 in which the cartridge has a second opening therein, a pin on the combustion device adapted to extend into the second opening, and means on the combustion device adapted to strike said pin.
Claim 12
Dependent Claim
41 words
An encapsulated cartridge as defined in claim 2 in which the means for making the outlet comprises a reciprocable shutter and spring means operatively connected to the shutter to urge the shutter in front of the outlet nozzle on the cartridge.
Claim 13
Dependent Claim
50 words
An encapsulated cartridge as defined in claim 3 in which the means on the combustion device for removing the masking means comprises a projection having an opening thereiN to receive the outlet nozzle and a portion thereon which actuates the masking means to remove it from covering the outlet nozzle.
Claim 14
Dependent Claim
42 words
An encapsulated cartridge as defined in claim 1 in which the housing comprises a plurality of leaf springs which join to mask the outlet nozzle, the leaf springs having means thereon to open the leaf spring jointure thereby exposing the outlet nozzle.
Claim 15
Dependent Claim
75 words
An encapsulated cartridge as defined in claim 1 in which a fingerpiece is reciprocably mounted on the housing, spring means mounted on the fingerpiece to return the fingerpiece from an actuated to a rest position, hammer means mounted in cooperative relationship with the fingerpiece, energy storing means mounted between the fingerpiece and the hammer means such that said energy storing means imparts a force to the hammer means in response to actuation of the fingerpiece.
Claim 16
Dependent Claim
45 words
An encapsulated cartridge as defined in claim 13 in which a holding member on the combustion device maintains the hammer means in a cocked position and the fingerpiece has means thereon to release said holding member to thereby actuate the hammer which strikes the cartridge.
