ABSTRACT:
A projectile propelling assembly for use with a bow includes an elongated guide member for guiding a projectile to be shot by the bow. The guide member is mounted on the bow by a support and in its mounted position the guide member extends longitudinally in the direction of the shooting motion of the bowstring. In one embodiment of the invention the tension for the bow is provided by a spring, and in another embodiment, a pair of flexible bow arms is employed. A channel is provided for movement of a fluid and is operatively associated with the guide member. The bowstring is operatively associated with the tension source of the bow, the channel, and the guide member. The drawing movement of the bowstring increases the tension in the bow and when the bowstring is released, the tension of the bow acts on the fluid which in turn acts on the projectile to propel it from the bow. In one embodiment of the invention, when the bowstring is drawn into a drawn condition and then released, the bowstring is under no load and does not propel the projectile as it returns to an undrawn condition.
