Abstract

Abstract An elongated hollow cylindrical tube of relatively light and malleable metallic material has one end closed as by swedging to form the ball-striking end of a ball-bat. The other end of the cylinder is attenuated and narrowed to define the handle end of the ball-bat and is then flared outwardly at the open end, the marginal edge thereof being fluted or plain. A cylindrical cup element is then secured onto said open end, the wall of cup being compressed radially inwardly about the flaring and locked thereabout against rotary or longitudinal movement with respect to the ball-bat.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 121 words
The method of making a metal ball-bat which comprises deforming the metal at one end of a hollow cylinder to close off said end, reducing the diameter of the cylinder at the other and open end of said cylinder to extend the length thereof thereby to form a handle portion of uniform diameter, forming an annular peripheral recess in the handle spaced from the open end of the cylinder, applying an inverted side-walled cap of metal over the said other end and crimping the side walls of the cap against the open end of the cylinder and forcing the ends of the side walls into the recess to lock the cap against rotary and longitudinal movemenT with respect to the bat.
Claim 2
Independent Claim 121 words
The method of making a metal ball-bat which comprises deforming the metal at one end of a hollow cylinder to close off said end, reducing the diameter of the cylinder at the other and open end of said cylinder to extend the length thereof thereby to form a handle portion of uniform diameter, forming an annular peripheral recess in the handle spaced from the open end of the cylinder, applying an inverted side-walled cap of metal over the said other end and crimping the side walls of the cap against the open end of the cylinder and forcing the ends of the side walls into the recess to lock the cap against rotary and longitudinal movemenT with respect to the bat.
Claim 3
Dependent Claim 28 words
The method of claim 1 which includes the step of reducing the diameter of the cylinder on a taper from the original diameter thereof to the handle end.
Claim 4
Independent Claim 137 words
The method of making a metal ball-bat which comprises deforming the metal at one end of a hollow cylinder to close off said end, reducing the diameter of the cylinder at the other and open end of said cylinder to extend the length thereof to form a handle portion of uniform diameter, forming an annular peripheral recess in the handle spaced from the open end of the cylinder, flaring the said open end outwardly and fluting the marginal border thereof, applying an inverted sidewalled cap of metal over the said other and open end and crimping the side walls of the cap against the open end of the cylinder and forcing the ends of the side walls of the cap into the recess to lock the cap against rotary and longitudinal movement with respect to the bat.
Claim 5
Independent Claim 137 words
The method of making a metal ball-bat which comprises deforming the metal at one end of a hollow cylinder to close off said end, reducing the diameter of the cylinder at the other and open end of said cylinder to extend the length thereof to form a handle portion of uniform diameter, forming an annular peripheral recess in the handle spaced from the open end of the cylinder, flaring the said open end outwardly and fluting the marginal border thereof, applying an inverted sidewalled cap of metal over the said other and open end and crimping the side walls of the cap against the open end of the cylinder and forcing the ends of the side walls of the cap into the recess to lock the cap against rotary and longitudinal movement with respect to the bat.
Claim 6
Dependent Claim 44 words
The method of claim 3, including the step of deforming the metal of the cap and of the fluted border of the handle end so that there is an interdigitation of cap and border metal preventing relative circumferential movement of the cap and handle.
