Abstract
Abstract A pistol to propel and spin ring-like projectiles such as bottle caps. An impeller is released by a trigger and an off-center mounted hammer strikes and propels the bottle caps with a spin. As the bottle cap exits from the barrel of the gun, a wall mounted rib imparts an additional spinning force to the bottle cap. The trigger of the pistol has a portion for engaging and holding an inside surface of the peripheral wall of the projectile in the firing chamber. When the trigger is actuated the portion engaging the projectile will pivot away and permit the spring biased plunger to engage and propel the projectile.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A pistol for propelling projectiles comprising: a projectile having bottle cap shape defining an inverted cavity with an annular downwardly extending peripheral wall; a firing chamber receiving said projectile; a handle connected to said firing chamber; impeller means movably connected to said firing chamber and operative between a cocked position and through a firing stroke for impacting a spin producing and propelling force on the projectile, at the point of impact with the projectile; a trigger means operatively associated with said handle for releasing said impeller means to apply the spin producing and propelling force on the projectile; and restraining means operatively connected to said trigger means and adapted for engaging and holding an inside surface of said peripheral wall of the projectile in said firing chamber until said trigger means is moved, and said restraining means then disengaging from the projectile to release the same for firing.
Claim 2
Dependent Claim
148 words
A pistol for propelling projectiles comprising: a projectile having bottle cap shape defining an inverted cavity with an annular downwardly extending peripheral wall; a firing chamber receiving said projectile; a handle connected to said firing chamber; impeller means movably connected to said firing chamber and operative between a cocked position and through a firing stroke for impacting a spin producing and propelling force on the projectile, at the point of impact with the projectile; a trigger means operatively associated with said handle for releasing said impeller means to apply the spin producing and propelling force on the projectile; and restraining means operatively connected to said trigger means and adapted for engaging and holding an inside surface of said peripheral wall of the projectile in said firing chamber until said trigger means is moved, and said restraining means then disengaging from the projectile to release the same for firing.
Claim 3
Dependent Claim
41 words
The pistol of claim 1 wherein, said impeller means comprises a plunger movable in said firing chamber, and a hammer operatively connected to said plunger and adapted for delivering an off-center force to the projectile for propelling and spinning the same.
Claim 4
Dependent Claim
31 words
The pistol of claim 2 and further including: urging means operatively connected to said plunger and operative when released for driving said plunger from said cocked position through said firing stroke.
Claim 5
Dependent Claim
47 words
The pistol of claim 2 wherein, said firing chamber comprises a generally rectangular barrel, and a movable cover means assembled to said firing chamber in the vicinity of said barrel and adapted to be moved to expose a loading zone of said barrel for loading projectiles therein.
Claim 6
Dependent Claim
33 words
The pistol of claim 4 wherein, said impeller means further comprises means in said barrel at the exit thereof, adapted for contacting edgewise the forward moving projectile to cause the same to spin.
Claim 7
Dependent Claim
51 words
The pistol of claim 1 wherein, said trigger means includes a stop means engagable with said impeller and active for preventing the same from over-cocking, and a sear engagable with said impeller means and active for restraining said impeller means in the cocked position until release by moving said trigger means.
Claim 8
Dependent Claim
188 words
A pistol for propelling projectiles comprising: a projectile having bottle cap shape defining an inverted cavity with an annular downwardly extending peripheral wall; a firing chamber receiving said projectile; a handle connected to said firing chamber; impeller means movably connected to said firing chamber and operative between a cocked position and through a firing stroke for imparting a propelling force on the projectile at the point of impact therewith; compound spinning means operatively associated with said impeller means and active for imparting a spin to the projectile at the point of impact between said impeller means and the projectile, and active to apply a further spin producing force on the projectile as the same emerges from said firing chamber; a trigger movably assembled to said handle means and operative for releasing said impeller means from said cocked position; and restraining means operatively connected to said trigger means and adapted for engaging and holding an inside surface of said peripheral wall of the projectile in said firing chamber until said trigger means is moved, and said restraining means then disengaging from the projectile to release the same for firing.
Claim 9
Dependent Claim
188 words
A pistol for propelling projectiles comprising: a projectile having bottle cap shape defining an inverted cavity with an annular downwardly extending peripheral wall; a firing chamber receiving said projectile; a handle connected to said firing chamber; impeller means movably connected to said firing chamber and operative between a cocked position and through a firing stroke for imparting a propelling force on the projectile at the point of impact therewith; compound spinning means operatively associated with said impeller means and active for imparting a spin to the projectile at the point of impact between said impeller means and the projectile, and active to apply a further spin producing force on the projectile as the same emerges from said firing chamber; a trigger movably assembled to said handle means and operative for releasing said impeller means from said cocked position; and restraining means operatively connected to said trigger means and adapted for engaging and holding an inside surface of said peripheral wall of the projectile in said firing chamber until said trigger means is moved, and said restraining means then disengaging from the projectile to release the same for firing.
Claim 10
Dependent Claim
46 words
The pistol of claim 7 wherein: said impeller means comprises a plunger movable in said firing chamber, and said compound spinning means comprises a hammer operatively connected to said plunger and adapted for delivering an off-center force to the projectile for propelling and spinning the same.
Claim 11
Dependent Claim
36 words
The pistol of claim 7 wherein: said compound spinning means further comprises means assembled to said firing chamber at the exit thereof adapted for contacting edgewise the forward moving projectile to cause the same to spin.
