Abstract: A fungo batting assisting machine having a frame; a cradle mounted upon the frame, the cradle having a ball percussion port; a hammer; a first pivot joint interconnecting the hammer and the frame so that the hammer may move between a spring energy position underlying the ball percussion port and a ball driving position overlying the spring energy position; a ball driving spring normally positioning the hammer between its spring energy and ball driving positions; a trip arm extending from the hammer; a pawl arm; a second pivot joint interconnecting the pawl arm and the frame so that the a pawl arm may move between a trip arm carrying position and a trip arm releasing position; and an actuation lever extending from the pawl arm.

Abstract: A ball pitching machine having a first “U” bracket having front and rear arms, the first “U” bracket further having rocker beam base spanning between the front and rear arms; a second “U” bracket having left and right arms, each left and right arm having a distal end, the first “U” bracket's front arm comprising the second “U” bracket; a third “U” bracket having left and right arms, the third “U” bracket having sling pinching pivot arms adapted for moving the left and right arms between sling pinching and sling releasing positions; left and right elastomeric ties, each having proximal and distal ends, the proximal ends of the left and right elastomeric ties being respectively fixedly attached to the distal ends of the second “U” bracket's left and right arms; a sling having left and right ends, the distal ends of the left and right elastomeric ties being respectively fixedly attached to the sling's left and rights ends; and a trajectory adjusting carriage fixedly attached to and supporting the first “U” brack
