  • Patent number: 4501427
    Abstract: A target apparatus for pistol shooters has a plurality of target boards (28) provided at spaced intervals in a frame, the lower frame member (10) of which is hollow. Each support (30) for each target board (28) has an axle (34) journalled in a mounting plate (36) on the lower frame member (10), with a pinion wheel (37) on each axle (34). Respective racks (42) are provided on an operating rod (39) which is reciprocally moved by a double acting pneumatic cylinder (13). A damping assembly (44) has a piston (48), connected to the operating rod (39), slidably movable in a cylinder (45) which has bleed holes (55) at each end to damp the movement of the piston (48) and inlet holes (56) normally closed by a valve (57) which enables the cylinder to be maintained full of oil as the piston (48) moves in the cylinder. Oil fills the lower frame member (10) and acts as the damping medium, the oil being in free communication with the cylinder when the piston (48) is intermediate its stroke, where no damping is required.
