Abstract
Abstract A ball rammer includes a rammer head formed of a solid member of cold rolled steel, having an elongated cylindrical surface and flat ends which are joined to the cylindrical surface by the respective arcuate surfaces. A handle of the ball rammer is joined to the head approximately tangentially at a mid point of the cylindrical surface. One of the flat surfaces is smaller than the other and is somewhat pointed so that different effects are realized by using each end to strike a game ball.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
240 words
An instrument for striking a relatively hard plastic ball, comprising: a. an elongated cylindrical head of hard and relatively unyielding metal having a first striking surface comprising the cylindrical surface of said rammer head, said rammer head having adjacent one end thereof a first arcuate surface curved toward the axis of said cylindrical surface for a predetermined first arcuate distance and joined tangentially with said cylindrical surface at one edge and with said rammer head terminating in a second striking surface at said one end, said second striking surface having a planar ball striking surface perpendicular to said axis and being tangent to said first arcuate surface at its other edge, said rammer head having adjacent the other end thereof a second arcuate surface curved toward said axis for a predetermined second arcuate distance and joined tangentially with said cylindrical surface at one edge and with said rammer head terminating in a third striking surface at said other end, said third striking surface having a planar ball striking surface perpendicular to said axis and being tangent to said second arcuate surface at its other edge, said first arcuate distance being different than said second arcuate distance and said third striking surface having a greater area than said second striking surface; and b. a shaft; said shaft having a handle at one end and head attachment means at its other end for securing said shaft to said rammer head perpendicularly thereto.
Claim 2
Dependent Claim
240 words
An instrument for striking a relatively hard plastic ball, comprising: a. an elongated cylindrical head of hard and relatively unyielding metal having a first striking surface comprising the cylindrical surface of said rammer head, said rammer head having adjacent one end thereof a first arcuate surface curved toward the axis of said cylindrical surface for a predetermined first arcuate distance and joined tangentially with said cylindrical surface at one edge and with said rammer head terminating in a second striking surface at said one end, said second striking surface having a planar ball striking surface perpendicular to said axis and being tangent to said first arcuate surface at its other edge, said rammer head having adjacent the other end thereof a second arcuate surface curved toward said axis for a predetermined second arcuate distance and joined tangentially with said cylindrical surface at one edge and with said rammer head terminating in a third striking surface at said other end, said third striking surface having a planar ball striking surface perpendicular to said axis and being tangent to said second arcuate surface at its other edge, said first arcuate distance being different than said second arcuate distance and said third striking surface having a greater area than said second striking surface; and b. a shaft; said shaft having a handle at one end and head attachment means at its other end for securing said shaft to said rammer head perpendicularly thereto.
Claim 3
Dependent Claim
17 words
An instrument as claimed in claim 1 wherein said rammer head is of a solid steel material.
Claim 4
Dependent Claim
55 words
An instrument as claimed in claim 1 wherein said attachment means comprises the lower part of said shaft being flattened into a curvilinear surface of substantially the same curvature as said cylindrical surface, said curvilinear surface being secured to said rammer head at the cylindrical surface thereof and substantially tangentially thereto in a wrap-around manner.
Claim 5
Dependent Claim
17 words
An instrument as claimed in claim 3 wherein said rammer head is of a solid steel material.
Claim 6
Dependent Claim
24 words
An instrument as claimed in claim 4 wherein said shaft is secured to said rammer head midway between the ends of said cylindrical surface.
Claim 7
Dependent Claim
17 words
An instrument as claimed in claim 1 wherein both said arcuate surfaces have a truncated hemispherical configuration.
