Apparatus for propelling projectiles and particularly suited to throwing footballs. The apparatus includes (a) a structural frame having elongate bearing surfaces and a forward end from which the projectiles are ejected; (b) a ball carriage adapted to contain the projectile, the carriage being slidingly mounted on the bearing surfaces; (c) at least one resilient member for so urging the carriage along the bearing surfaces towards the forward end that the projectile is propelled from the carriage at the forward end of the frame; and (d) a ball rotating assembly mounted on the ball carriage for applying rotation to the projectile as the projectile is propelled from the apparatus. A locking apparatus may also be provided for releasably locking the ball carriage relative to the structural frame. The propelling apparatus, when used in conjunction with a supporting pole, can be accurately aimed and operated by one person.
