Abstract

A device for training a baseball pitcher has a baseball catching element operative for catching a baseball, a baseball throwing element operating for throwing a caught baseball in accordance with a catapult principle, and a drive connecting with the baseball throwing element and actuating the baseball throwing element when the baseball is received by the baseball throwing element.

Claims

1. A device for training a baseball pitcher, comprising baseball catching means operative for catching a baseball;

baseball throwing means operating for throwing a caught baseball; and

drive means connecting with said baseball throwing means and driving said baseball throwing means when the baseball is received by said baseball throwing means; and

valve means connected with said drive means and with said receiving plate so that when said receiving plate is moved under the action of the baseball, said valve means is activated and allows a supply a working medium from a source of the working medium to said drive means to activate said drive means and thereby to displace said throwing arm.

2. A device as defined in claim 1, wherein said catching plate is formed so that when it moves to its initial position it closes said valve.

3. A device for training a baseball pitcher, comprising baseball catching means operative for catching a baseball;

baseball throwing means operating for throwing a caught baseball; and

drive means connecting with said baseball throwing means and driving said baseball throwing means when the baseball is received by said baseball throwing means, said receiving means including a receiving plate, said throwing means include a throwing arm connected with said drive means and retained in an absence of a baseball, said receiving means being movable under an action of a weight of the baseball so as to release said throwing arm, whereupon said drive turns said throwing arm so that said throwing arm takes the baseball from said receiving plate and throws it;

a locking element for locking and unlocking said receiving plate;

a contact pin actuatable by said throwing arm; and

a rod connecting said contact pin with said locking element, so that when said throwing arm contacts said contact pin at an end of throwing movement, said locking element releases said receiving plate and said receiving plate is moved to its initial position.
