Abstract
Abstract A device is provided for instructing and training in the aiming of a billiard cue ball for proper contact with an object ball. The device is a flat compliant structure having an elongated shape possessing symmetry about a longitudinal axis and comprising an object ball locator, an aiming pattern, and a pointer centered on said axis. The device is sufficiently thin so as not to deflect billiard balls during play, and small enough in size to be utilized near the corners of a billiard table playing surface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
184 words
A training device for the aimining of a billiard ball comprised of compliant sheet material of uniform thickness having a generally elongated shape consisting of a body portion bounded by two extreme portions and an outer periphery possessing symmetry about a longitudinal axis, an object ball locator having the form of an aperture or depression centered on said axis within said body portion, an aiming pattern of generally circular boundary configuration constituting one extreme portion of said device and having visibly distinctive indicia radiating from a central point lying on said axis at a distance from the center of said object ball locator equal to the diameter of a billiard ball to be used in conjunction with said device, and pointing means adjacent the other extreme portion of said device and possessing a visibly distinctive symmetric bilateral taper culminating in an apex positioned on said axis and directed away from said aiming pattern, the thickness of said sheet material being not greater than 20 mils so that a billiard ball will not be significantly deflected when rolling over game on a billiard table surface.
Claim 2
Dependent Claim
184 words
A training device for the aimining of a billiard ball comprised of compliant sheet material of uniform thickness having a generally elongated shape consisting of a body portion bounded by two extreme portions and an outer periphery possessing symmetry about a longitudinal axis, an object ball locator having the form of an aperture or depression centered on said axis within said body portion, an aiming pattern of generally circular boundary configuration constituting one extreme portion of said device and having visibly distinctive indicia radiating from a central point lying on said axis at a distance from the center of said object ball locator equal to the diameter of a billiard ball to be used in conjunction with said device, and pointing means adjacent the other extreme portion of said device and possessing a visibly distinctive symmetric bilateral taper culminating in an apex positioned on said axis and directed away from said aiming pattern, the thickness of said sheet material being not greater than 20 mils so that a billiard ball will not be significantly deflected when rolling over game on a billiard table surface.
Claim 3
Dependent Claim
36 words
The device of claim of claim 1 wherein the diameter of the generally circular boundary of said aiming pattern is greater than said distance between said central point and the center of said object ball locator.
Claim 4
Dependent Claim
16 words
The device of claim 1 fabricated from a single integral piece of compliant thin sheet material.
Claim 5
Dependent Claim
52 words
The device of claim 1 wherein the underside of said device is provided with a surface having adhesive affinity for the playing surface of a billiards table, said adhesive affinity being based upon a contact - type adhesive composition having a tackiness capable of repeatedly bonding to and separating from other surfaces.
Claim 6
Dependent Claim
30 words
The device of claim 1 wherein the upper side of said device contains a felt-like surface having frictional properties similar to those of the playing surface of a billiards table.
Claim 7
Dependent Claim
16 words
The device of claim 5, said felt-like surface having been produced by a floc deposition technique.
Claim 8
Dependent Claim
24 words
The device of claim 1 wherein said aiming pattern is comprised of paired elongated indicia diametrically opposed and equiangularly disposed about said central point.
Claim 9
Dependent Claim
18 words
The device of claim 7 wherein at least one pair of indicia is disposed perpendicular to said axis.
Claim 10
Dependent Claim
30 words
The device of claim 1 wherein said body portion has a width, measured perpendicular to said axis, smaller than the diameter of the generally circular boundary of said aiming pattern.
