Abstract
Magazine for an immersed underwater crossbow containing a string and allowing for the rapid introduction by suction of the string and its natural arrangement by means of retracting means as well as its exit without difficulty. By pulling on the shank of the piston pump, a depression is produced within the magazine and the string rapidly enters the magazine across its end and, arranges itself naturally against the piston. One can thus arrange several meters without difficulty. The exit is accomplished in the same way.
Claims11
A crossbow apparatus capable of use while submerged under water comprising:
- a projectile operatively attached to said apparatus, a string attached at one end to said projectile, means for retracting said string, said means for retracting being attached to the other end of said string, a magazine in which said string normally reposes until the projectile is fired, and means to actuate said retracting means after the projectile is fired thus causing low pressure to develop in said magazine with subsequent withdrawing of said string due to water being withdrawn into said magazine.
