Abstract: A target or clay pigeon may comprise a stopper for hermetically sealing an outlet hole. The stopper may automatically or non-automatically open the outlet hole. In one embodiment, the outlet hole (91) is hermetically sealed by a film (92) with a thread integrated with this stopper, the free extremity of which departs from the film (92) and is connected to a weight (94). With the rotation of the clay pigeon or target, the weight (94) pulls on the wire and tears the stopper, thus freeing the colored material.

Abstract: A target throwing device having a base and a support rotatably mounted on the basis for swinging movement about an upright axis. A throwing arm is rotatably mounted on the support for throwing targets. Structure is provided for eccentrically swinging the support back and forth while throwing targets. A mechanism is connected within a first eccentric drive connection and is operative in response to movement of the first eccentric drive for superimposing an eccentric series of short back and forth swings on the support during each long swing of the support. A second eccentric drive transmits eccentric motion to the support through a member that is movable with respect to the guide mechanism.

Abstract: Apparatus for the throwing of clay pigeon type targets, including a throwing arm and an automatic target loading device therefor, is mounted on a trailer chassis so as to be transportable. The transportable target throwing apparatus also includes mechanisms for immobilizing and leveling the chassis on which the loading device and throwing arm are mounted and a shield which protects the loading device and throwing arm from errant shots when in use. The shield, or protective cover, is partially removable from the trailer to permit unobstructed operation of the apparatus.

Abstract: Apparatus for throwing objects, and particularly "clay pigeons" for target shooting, wherein a spring driven throwing arm is locked in a position wherein the spring is in tension but the arm must be further mechanically driven against the spring tension to an equilibrium point where the throwing stroke will take place under the influence of the spring. The position of the throwing arm is controlled by an electric motor, a pair of parallel circuits for controlling the energization of the motor and a drive train between the motor and the shaft which supports the throwing arm; the drive train including a ratchet type arrangement which constrains the arm to movement in only one direction and "captures" the arm on "rebound" of the spring at the end of a throw.
