  • Patent number: 7111620
    Abstract: The present invention provides a ball engagement device for use with a ball launching device, comprising a housing having first and second ends, an opening for accepting balls and a ball chamber adjacent to the opening. The device further includes a motor coupled to the housing and a pinion connected to and driven by the motor. The pinion drives a rack that has a ball engagement end, wherein the rack is slideably disposed along an interior portion of the housing. The device also includes a first switch disposed in the housing and that is operably configured to activate the motor to rotate the pinion in a first direction, the first switch is activatable by the presence of a ball in the ball chamber, a second switch disposed in the housing operably configured to rotate the pinion in an opposing second direction, a third switch disposed in the housing at a predetermined distance from the second switch and operably configured to deactivate the motor and a switch activation member disposed along the rack.

  • Patent number: 7040309
    Abstract: The present inventions provides a directing device for controlling the orientation of a ball launching device, comprising a first member, a second member pivotally attached to the first member, and a third member disposed substantially parallel to the second member, rotatably connected to the second member and operably configured to receive the ball launching device. The device further includes a first actuator connected to the first and second members and, a second actuator connected to the first and third members. When the first actuator is actuated the second member pivots relative to the first member, and when the second actuator is actuated the third member rotates relative to the second member. This invention also provides an automatic ball throwing device having the directing device of this invention and a method of converting a pitching machine into the same. This invention further provides a hopper for use with the directing device.
