Level bubble for a golf club

Claim 2

In combination a position indicator mounted upon the shaft adjacent the handle of a golf club of the type normally used to loft a ball, to incline and position the golf club prior to swinging, comprising: a. a cup-shaped positioning head carrying a universal type level indicator; said level indicator comprising a bubble in fluid beneath a section of a spherical glass, a circular marker centered on the glass to indicate the level position of the bubble and a line marker on the glass bisecting said circular marker to indicate direction; and b. a mount means having a clamp to grip the club shaft and a boss to hold the positioning head, said clamp includes a clamp arm and an opposing clamp bar which are secured together; wherein the clamp can be adjustably tightened to permit rotative adjustments of the mount means about the shaft; wherein the connection between the boss and the positioning head is a ball and socket type joint to permit tippable and rotative adjustments of the head upon the boss; said boss is a cup having a hemispherical cavity and the positioning head includes; a spherical base adapted to be fitted into the cup; said cup includes: a hemispherical, outer surface; a washer formed as a spherical segment fitted against the exterior of the cup; an orifice at the base of the cup; wherein a lock means is associated with the boss and the head to lock the head in position upon the boss; said lock means includes a lock screw extended through the washer, through the orifice and into the spherical base, and wherein the orifice is larger in diameter than the diameter of the lock screw to permit position adjustments between the head and boss; and whereby the golf club is placed with the hancle at a selected proper inclination and rotated to position the head of the club for hitting a ball in the desired direction of flight and the clamp means and the positioning head are rotated and tilted to indicate the proper position for holding the club prior to swinging it for hitting the golf ball, the bubble will be juxtaposed with the circular marker and the line marker will be aligned with the direction of flight to thereby provide a predetermined proper setting for repeatedly properly positioning the club.

Claim 3

The position indicator defined in claim 1, wherein said direction marker is adapted to indicate a proper swing of the club whenever the level indicator indicates level along the course of the direction marker.

Claim 4

In combination a position indicator mounted upon the shaft adjacent the handle of a golf club of the type normally used to loft a ball, to incline and position the golf club prior to swinging, comprising: a. a cup-shaped positioning head carrying a universal type level indicator; said level indicator comprising a bubble in fluid beneath a section of a spherical glass, a circular marker centered on the glass to indicate the level position of the bubble and a line marker on the glass bisecting said circular marker to indicate direction; and b. a mount means having a clamp to grip the club shaft and a boss to hold the positioning head; said clamp includes a clamp arm and an opposing clamp bar which are secured together; wherein the clamp can be adjustably tightened to permit rotative adjustments of the mount means about the shaft; wherein the connection between the boss and the positioning head is a ball and socket type joint to permit tippable and rotative adjustments of the head upon the boss; said boss has a hemi-spherical upper surface and said cup has a spherical cavity adapted to shiftably seat upon this upper surface; said boss includes a spherical cavity at its undersurface; a washer having a spherical upper surface fitted into the spherical cavity; an orifice through the boss; wherein a lock means is associated with the boss and the head to lock the head in position upon the boss; said lock means includes a lock screw extended through the washer, through the orifice and into the cup, and wherein the orifice is larger in diameter than the diameter of the lock screw to permit position adjustments between the head and boss; and whereby when the golf club is placed with handle at a selected proper inclination and rotated to position the head of the club for hitting a ball in the desired direction of flight and the clamp means and the clamp means and the positioning head are rotated and tilted to indicate the proper position for holding the club prior to swinging it for hitting the golf ball, the bubble will be juxtaposed with the circular marker and the line marker will be aligned with the direction of flight to thereby provide a predetermined proper setting for repeatedly properly positioning the club.

Claim 5

In combination a position indicator mounted upon the shaft adjacent the handle of a golf club of the type normally used to loft a ball, to incline and position the golf club prior to swinging, comprising: a. a cup-shaped positioning head carrying a universal type level indicator; said level indicator comprising a bubble in fluid beneath a section of a spherical glass, a circular marker centered on the glass to indicate the level position of the bubble and a line marker on the glass bisecting said circular marker to indicate direction; and b. a mount means having a clamp to grip the club shaft and a boss to hold the positioning head; said clamp includes a clamp arm and an opposing clamp bar which are secured together; wherein the clamp can be adjustably tightened to permit rotative adjustments of the mount means about the shaft; wherein the connection between the boss and the positioning head is a ball and socket type joint to permit tippable and rotative adjustments of the head upon the boss; said boss has a hemi-spherical upper surface and said cup has a spherical cavity adapted to shiftably seat upon this upper surface; said boss includes a spherical cavity at its undersurface; a washer having a spherical upper surface fitted into the spherical cavity; an orifice through the boss; wherein a lock means is associated with the boss and the head to lock the head in position upon the boss; said lock means includes a lock screw extended through the washer, through the orifice and into the cup, and wherein the orifice is larger in diameter than the diameter of the lock screw to permit position adjustments between the head and boss; and whereby when the golf club is placed with handle at a selected proper inclination and rotated to position the head of the club for hitting a ball in the desired direction of flight and the clamp means and the clamp means and the positioning head are rotated and tilted to indicate the proper position for holding the club prior to swinging it for hitting the golf ball, the bubble will be juxtaposed with the circular marker and the line marker will be aligned with the direction of flight to thereby provide a predetermined proper setting for repeatedly properly positioning the club.

Claim 6

The position indicator defined in claim 3, including: a direction marker associated with the level indicator adapted to indicate the proper direction for placement of the club and to indicate a proper swing of the club whenever the level indicator indicates level along the course of the direction marker.
