Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
A projectile for conveying and dispersing lachrymating material in an aerosol form comprising: a. a hollow enclosing shell having an impacting portion at one end and a base at the other end thereof. b. a container having a quantity of lachrymating material under pressure within the shell; c. valve means for the container disposed adjacent the base of the shell for dispensing the said lachrymating material; d. a plurality of stabilizing fins swingably carried by and extending outwardly of the base. e. a washer shaped member carried in the base of the shell said washer shaped member having a central opening therein; f. an actuating plunger slidably carried within the washer opening in alignment with the valve means; g. locking means engagable with the actuating plunger until shell impacting; h. an inertial member, slidably disposed about the plunger and overlying the locking means and; i. tabs carried by the fins to hold the locking means in engagement with the plunger and inertia member until launching of the shell.
Claim 2
Dependent Claim
168 words

Claim 3
Dependent Claim
29 words
A projectile according to claim 1 in which the impacting portion of the shell is weighted and the lachrymating material is a tear gas and an aerosol forming propellant.
Claim 4
Dependent Claim
23 words
A projectile according to claim 1 in which the stabilizing fins are provided with springs yieldably urging them into an open, operative position.
Claim 5
Dependent Claim
30 words
A projectile according to claim 1 in which the actuating plunger is axially bored to dispense the lachrymating material therethrough and spring loaded in the direction of the container valve.
Claim 6
Dependent Claim
38 words
A projectile according to claim 1 in which the locking means comprises a plurality of balls, ball receiving recesses in the actuating plunger and a ring on the inertial member overlying the locking balls in the locked position.
Claim 7
Dependent Claim
38 words
A projectile according to claim 1 in which an axial tube is disposed between the actuating plunger and the inertial member said tube having ball receiving openings therein whereby the locking balls are released therethrough upon projectile impact.
