Definitions

  • the new apparatus allows ofdispensing with a professor or an expert player; it can be actuated by a child; if need be, it can be mechanically driven so as to be absolutely automatic.
  • the apparatus forming the subject-matter of the invention is essentially character ized by a spring device which is bent and which, when it is released strikes the ball in the same way as a blow froma racket, then projects it according to the desired trajectory and in the required direction.
  • his feedin device can be set in such a way that the hall struck by the spring can occupy a diiferent position in the path of this spring, thus modifying at will the trajectory.
  • a crank actuates a leaf spring or springs the free end of which encounters an adjustable abutment which stops the s ring until the latter, having been sufliciently ent, frees itself from the abutment, suddenly relaxes and strikes the ball.
  • Fig. 1 is a side view of the a paratus.
  • Fig. 2 is a section made accor ing to line .AA of Fig. 1.
  • Fig. 3 is a partial front view corresponding to Fig. 1.
  • Fig. 4 is a side view'of a slightly modified form of the invention.
  • the new apparatus comprises a frame a, of suitable shape, carrying a socket b in which can freely rotate a shaft 0 on which is rigidly secured a crank d.
  • a drum e On this shaft is also rigidly secured a drum e on which is attached the end of a leaf spring f, for instance by means of a bolt 7.
  • the spring winds on a portion of the periphery of the drum and extends in an arm g, the end of which is slightly curved.
  • This end 9 comes opposite an abutment k which can be provided with a. roller for diminishing the friction.
  • abutment is carried by a plate 6 provided with a series of holes 72 this permittin to insert the abutment in one of these ho es, to immobilize it therein by a wing nut h and to adjust the distance between the said abutment and the ball j to be thrown.
  • Another abutment la is adapted to limit the relaxation of the spring.
  • the ball j is the first one of a column of balls filling a feeding conduit Z.
  • the lower end of the latter has an aperture or recess m (Fig. 3) permitting the passage of the spring.
  • an aperture on the front side allows the issue of the projected ball.
  • the conduit Zis carried by the plate 2'.
  • the latter is so mounted that it can rotate concentrically with the axis 0 and it can be locked in the required position by means of clamping screws 0 inserted in circular openings n in the said plate.
  • the feeding conduit Z is filled with balls. Forthrowing the balls, it suifices to turn the crank d. ⁇ Vhen the spring 9 encounters the abutment h, it is stopped. It is then bent until it frees itself from the abutment h.
  • the base of this com duit is provided with a slightly projecting nose 9.
  • a system for feedin the balls, an elastic system comprising a late spring and a rotary shaft carrying the plate sprin an abutment for arresting this plate spring 'placed at a certain distance from the ball to' be thrown, a support carrying the abutment and means for regulating the position of this support concentrically with respect to the sha 2.
