Abstract
A ball projecting machine having a C-shaped arm that provides the ability to adjust the length or elevation of pitched balls. The C-shaped arm connects a ball projecting head to a stand, with the ball projecting head affixed to one end of the C-shaped arm, and the C-shaped arm is slidably engaged through a frame atop the stand to allow rotation of the ball projecting head about a horizontal axis. A center of gravity of the ball projecting head in combination with the C-shaped arm facilitates stability of the ball projecting machine when the C-shaped arm is slid up or down. A locking device, when loosened, allows the C-shaped arm to slide up or down through the frame.
Claims20
A ball projecting machine for projecting a ball, comprising:
- a frame including a stand and at least a first locking device;
- a ball projecting head positioned apart from the frame, the ball projecting head including a first wheel for contacting the ball and a motor that drives the first wheel;
- and
- a generally C-shaped arm having first and second ends, the C-shaped arm being coupled at the first end to the ball projecting head, the C-shaped arm slidably engaging the frame at the first locking device, the first locking device positionable between a locked position wherein the frame affixes to one of a plurality of spaced-apart locations along the C-shaped arm between the first and second ends, and an unlocked position wherein the C-shaped arm is slidably movable relative to the frame between the plurality of locations along the C-shaped arm.
A ball projecting machine for projecting a ball, comprising:
- a ball projecting head spaced apart from and situated atop a stand, the ball projecting head including a first wheel spaced apart from an opposing surface by a distance roughly equal to a diameter of a ball, and a motor that drives the first wheel;
- a generally C-shaped arm that connects the ball projecting head to the stand, wherein the ball projecting head is affixed to one end of the C-shaped arm, and the C-shaped arm is slidably engaged through a frame atop the stand to allow rotation of the ball projecting head about a horizontal axis, wherein a center of gravity of the ball projecting head in combination with the C-shaped arm facilitates movement of the ball projecting machine when the C-shaped arm is slid up or down;
- and
- a locking device with a press-fit connection that, when disengaged, allows the C-shaped arm to slide up or down through the frame.
