Abstract

Abstract A pair of spaced, resiliently tired wheels are mounted on a base for axial rotation in a common plane, the spacing between the wheels being less than the diameter of a ball to be thrown and the rotational speed of each wheel being adjustable independently of the other. The base is supported above a ball and socket universal mounting, whereby to afford angular adjustment of said rotational plane in all directions about a common pivot point. The base member is locked in a desired position by the operation of a manual control device that operates to bring the base member against the ball of the ball and socket joint. Electrical controls are present to control the speed of rotation of the coacting wheels. These adjustments of relative rotational speeds and plane of rotation of the wheels afford wide variations in the direction, type, velocity and curvature of a ball ejected from between the wheels.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 304 words
A ball throwing device, comprising: a. a base member, b. a pair of drive motors mounted on the base member and each having a rotary output shaft, c. a pair of wheels mounted one on each of said output shafts and arranged in spaced relation for rotation in a substantially common plane, the spacing between the wheels being less than the diameter of a ball to be thrown, d. a base support, e. universal mounting means for permitting adjustment of the base member angularly in all directions relative to the base support about a single pivot point spaced from said common plane of rotation of the wheels, said universal mounting means including a ball, said ball being positioned between the base member and base support and secured to one of the base member and base support, and one portion of the other of said base and base support comprising a ball-receiving socket for receiving said ball, f. a handle connected to the base member for varying the angular position of said base member with respect to said base support, and g. clamp means for releasably securing together said base member, base support and ball, said clamp means releasably interengaging the ball and socket, said clamp means including 1. a plate member engaging said ball at points spaced from the largest diameter of said ball and on the ball surface opposite the surface engaged by said socket, 2. a manual control member, and 3. connector means coacting with said control member for adjustably interconnecting said plate member and the one of said base member and base support carrying the socket, and said connector means being operable by the control member to move the plate member toward and away from the socket to lockably release said handle and base member with respect to said base support.
Claim 2
Dependent Claim 304 words
A ball throwing device, comprising: a. a base member, b. a pair of drive motors mounted on the base member and each having a rotary output shaft, c. a pair of wheels mounted one on each of said output shafts and arranged in spaced relation for rotation in a substantially common plane, the spacing between the wheels being less than the diameter of a ball to be thrown, d. a base support, e. universal mounting means for permitting adjustment of the base member angularly in all directions relative to the base support about a single pivot point spaced from said common plane of rotation of the wheels, said universal mounting means including a ball, said ball being positioned between the base member and base support and secured to one of the base member and base support, and one portion of the other of said base and base support comprising a ball-receiving socket for receiving said ball, f. a handle connected to the base member for varying the angular position of said base member with respect to said base support, and g. clamp means for releasably securing together said base member, base support and ball, said clamp means releasably interengaging the ball and socket, said clamp means including 1. a plate member engaging said ball at points spaced from the largest diameter of said ball and on the ball surface opposite the surface engaged by said socket, 2. a manual control member, and 3. connector means coacting with said control member for adjustably interconnecting said plate member and the one of said base member and base support carrying the socket, and said connector means being operable by the control member to move the plate member toward and away from the socket to lockably release said handle and base member with respect to said base support.
Claim 3
Dependent Claim 5 words
a manual control member, and
Claim 4
Dependent Claim 5 words
a manual control member, and
Claim 5
Dependent Claim 91 words
The ball throwing device of claim 1 wherein the ball is on the base support, the socket is carried by the base member, and the clamp plate member has an opening therethrough of smaller diameter than the ball, the control member interengaging the plate and base member for releasably clamping them to the ball. 3. The ball throwing device of claim 1 includes wheel drive motors of the variable speed electric type, and electric control means is associated with each motor for varying the speed thereof independently of the other motor.
Claim 6
Dependent Claim 61 words
connector means coacting with said control member for adjustably interconnecting said plate member and the one of said base member and base support carrying the socket, and said connector means being operable by the control member to move the plate member toward and away from the socket to lockably release said handle and base member with respect to said base support.
Claim 7
Dependent Claim 61 words
connector means coacting with said control member for adjustably interconnecting said plate member and the one of said base member and base support carrying the socket, and said connector means being operable by the control member to move the plate member toward and away from the socket to lockably release said handle and base member with respect to said base support.
