Abstract
An apparatus for ejecting balls in which a pretensioning arrangement includes a loading device which is displaceable between a first and a second position, first and second locking members are brought to contact each other by displacement of the loading device to a first position as a pivot arm is thereby moved to the loading position, and displacement of the loading device to a second position produces pretensioning of the pivot arm in the loading position. As a result, the pivot arm has a position in which the apparatus is safe because the pivot arm is without tension in the shooting position. Also, the pivot arm can be moved to its loading position without a simultaneous pretensioning being effected. Pretensioning is only established when the pivot arms are in the loading position and are retained by the locking arrangement. Thus, the loading arrangement and shooting power can be varied.
