Launching device for training retrieving dogs

摘要

A launching device for training dogs to retrieve comprising a plurality of projectiles arranged to be launched by the launching device of the type which can be retrieved by the dog, a projectile mount arranged to support the plurality of projectiles such that the plurality of projectiles can be positioned one at a time to be launched automatically, a gas chamber wherein the gas is arranged to produce a force to launch the projectile, an actuating arrangement to actuate the gas in the gas chamber, at least one gas supply container for supplying the gas to the chamber, a remote operating means to launch the projectiles from a distance and a valve arrangement for controlling the amount of gas entering the gas chamber. The projectile mount is on a shaft having an axis in which the projectile mount can rotate. A motor is arranged to drive the shaft about the axis. A disk is mounted at a respective end of the shaft arranged to rotate about the axis. A plurality of engaging members are on an outer edge of the disk for engaging a switch. The switch is arranged to stop rotation of the motor such that the projectile is in position to be launched. The switch defines the actuating arrangement such that when the engaging members engage the switch the flow of gas to the gas chamber is stopped and ignited. The actuating arrangement has a sparking device defining a spark plug mounted on the gas chamber for igniting the gas and the sparking device is actuated by the switch when engaged by the engaging member.
