Abstract
Abstract A metal ball-bat and method of finishing a tubular metal ballbat at the large diameter end by securing a generally cylindrical resilient member within the end portion of the ball-bat. The resilient member is forceably inserted into the ball-bat end, and the end edge of the ball-bat deformed circumferentially inward to secure the resilient member within the bat. The resilient member also overlaps the end edge of the metal ball-bat as a safety feature.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
The method of securely inserting a sound-deadening end closure member within the large diameter end of a generally tubular metal ball-bat, which method comprises: a. forming a generally cylindrical, resilient member; b. forceably inserting the resilient member into the large diameter end of the metal ball-bat, so that the resilient member projects out of the ball-bat end a small predetermined distance; c. forming an inwardly projecting circumferential lip at the large diameter ball-bat end to securely engage the resilient member by; i. rotating a mounting plate upon which are symmetrically disposed a plurality of independently rotatable forming rollers spaced to accept the large diameter ball-bat end between the forming rollers; ii. moving the ball-bat relative to the forming rollers in the direction of the ball-bat longitudinal axis whereby the predeterminedly formed forming rollers deform the end portion of the ball-bat inward to securely engage the resilient end closure.
Claim 2
Independent Claim
148 words
The method of securely inserting a sound-deadening end closure member within the large diameter end of a generally tubular metal ball-bat, which method comprises: a. forming a generally cylindrical, resilient member; b. forceably inserting the resilient member into the large diameter end of the metal ball-bat, so that the resilient member projects out of the ball-bat end a small predetermined distance; c. forming an inwardly projecting circumferential lip at the large diameter ball-bat end to securely engage the resilient member by; i. rotating a mounting plate upon which are symmetrically disposed a plurality of independently rotatable forming rollers spaced to accept the large diameter ball-bat end between the forming rollers; ii. moving the ball-bat relative to the forming rollers in the direction of the ball-bat longitudinal axis whereby the predeterminedly formed forming rollers deform the end portion of the ball-bat inward to securely engage the resilient end closure.
Claim 3
Dependent Claim
38 words
The method specified in claim 1, wherein a generally cylindrical resilient article with rounded end surfaces, is molded and cut along its length to provide two resilient members of predetermined length and weight for insertion into the ball-bat.
Claim 4
Dependent Claim
19 words
The method specified in claim 1, wherein the metal ball-bat is rotated during forceable insertion of the resilient member.
