Abstract
Abstract There is disclosed a baseball supported by a downwardly curved, semirigid, composite cord, which in turn normally extends forwardly from the normally forwardly disposed end of a pole, the rearward end being swingable connected to a swing structure. Guy wires from the rear of the cord just forward of the pole extend to top of the swing structure and to the swing structure below the pole swing connection. Normally vertically extending coil springs, in plurality and spaced apart, extend from upper and lower cage members which extend diagonally outwardly and rearwardly from the front of the cage as disposed just rearwardly of the swing structure. When a batter strikes the ball with a bat the pole swings from the blow, and with the swing structure and rearwardly against the coil springs on the respective side of pole swing to urge the spring thus strike against by the pole, first to flex or bow responsive to the side swing of the pole, then to straighten back into vertical position. When the springs struck by the pole re-flex, or straighten up vertically, the counterflex of the springs imparts swinging motion in opposite direction to the pole, and the pole swings back at least to original position. When the ball returns, and at elevation in the strike zone, the batter again may swing at the ball. Obviously, a left handed batter stands to the right of the normal pole axis when he swings, while a right handed batter stands to the left of such axis.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
234 words
A baseball batting practice device comprising; a base structure having an elongated upright standard mounted thereon, said standard having intermediate its ends means mounting one end of an elongated pole thereon such that said pole is rotatable in a substantially horizontal plane about said standard, said pole having elongated and slightly flexible extension means on its outer end mounting a ball; a frame structure mounted on said base adjacent said standard and positioned a distance from said standard such that said pole will be engaged with said frame structure upon rotation in said horizontal plane; means mounted on said frame structure for engagement with said pole to cause said pole to rotate in the opposite direction after said means on said frame is engaged by said rotating pole; means on said standard for pivotally supporting one end of said pole for pivotal movement in a substantially vertical plane to allow said pole to be raised or lowered to a desired height of a batter and said pole will engage said means mounted on said frame when said ball is hit in one direction and will also engage said means mounted on said frame when said ball is hit in the direction opposite said one direction, each engagement of the pole with said means mounted on said frame causing said pole and ball to return substantially to a position from which said ball was hit.
Claim 2
Dependent Claim
234 words
A baseball batting practice device comprising; a base structure having an elongated upright standard mounted thereon, said standard having intermediate its ends means mounting one end of an elongated pole thereon such that said pole is rotatable in a substantially horizontal plane about said standard, said pole having elongated and slightly flexible extension means on its outer end mounting a ball; a frame structure mounted on said base adjacent said standard and positioned a distance from said standard such that said pole will be engaged with said frame structure upon rotation in said horizontal plane; means mounted on said frame structure for engagement with said pole to cause said pole to rotate in the opposite direction after said means on said frame is engaged by said rotating pole; means on said standard for pivotally supporting one end of said pole for pivotal movement in a substantially vertical plane to allow said pole to be raised or lowered to a desired height of a batter and said pole will engage said means mounted on said frame when said ball is hit in one direction and will also engage said means mounted on said frame when said ball is hit in the direction opposite said one direction, each engagement of the pole with said means mounted on said frame causing said pole and ball to return substantially to a position from which said ball was hit.
Claim 3
Dependent Claim
156 words
The batting practice device of claim 1 wherein said upright stand is a first elongated tubular member telescopically received in a second tubular upright member having length shorter than said first tubular member and mounted on said base; said first upright member having three tubular sleeves rotatably mounted thereon, said sleeves being a first sleeve mounted on the upper extremity of said first tubular member, a second sleeve mounted adjacent the lower extremity of said first tubular member, and a third sleeve mounted intermediate said first and second sleeves; said sleeves being held at a fixed vertical distance apart by a pair of elongated vertically standing, parallel angle members, attached at diametrically opposite points on each of said sleeves; said third sleeve being said means for mounting said one end of said elongated pole on said upright standard, said guy lines extending from the outer end of said elongated pole to said first and second sleeves.
Claim 4
Dependent Claim
44 words
The batting practice device of claim 1, wherein said slightly flexible extension means is an elongated tubular member having one of its ends telescopically receiving the outer end of said elongated pole, the other end of said tubular member having said ball mounted thereon;
Claim 5
Dependent Claim
86 words
The batting practice device of claim 3 wherein said other end of said tubular member telescopically extends into said ball to a distance intermediate its outer surface and core, said tubular member having a pair of opposing apertures intermediate its ends, the other end of said guy lines each extending through an aperture, passed longitudinally through said tubular member and into said ball, encircling the core of said ball and returned through said tubular member and apertures and terminating at said first and second rotatable sleeves.
Claim 6
Dependent Claim
29 words
The batting practice device of claim 1 wherein said means mounted on said frame structure for engagement with said pole is at least one elongated, vertically extending resilient member.
Claim 7
Dependent Claim
159 words
The batting practice device of claim 1 wherein said frame structure mounted on said base comprises two substantially identical triangular shaped frame members, fixedly spaced one above the other and being in substantially parallel horizontal planes; said frame members each being positioned relative to said upright standard such that two of their sides diverge from said upright standard defining left and right diverging vertical planes; said means mounted on said frame structure for engagement with said pole being at least one elongated resilient member lying in each of said planes and extending vertically and having its ends attached to said upper and low frame member sides, said pole being engagable with said resilient member substantially mid-way its ends; said pole being swingable against said resilient member in said left plane when said ball is hit by a righthanded batter and is swingable against said resilient member in said right plane when said ball is hit by a lefthanded batter.
