Swing-weight and static weight balance for golf clubs

Claim 2

A swing weight balance adapted to employ any substantially horizontal flat surface as a base comprising: an elongated rigid member having a first upright section at one end thereof for supporting a golf club shaft, a second upright section at the other end functioning as a positioning stop for a Golf club with means for holding the grip end of said shaft, and an integral rocker between said upright sections extending from said rigid member in a direction opposite said upright sections for the purpose of resting on said flat surface while in use; a balancing weight adjustable in position on said member between said upright sections; a graduated scale placed in a position on said member for indicating the swing weight of a golf club by the position of said balancing weight with respect thereto when its position is adjusted that only said rocker rests upon said horizontal flat surface; and means for compensating for an increase in the apparent swingweight balance of a golf club without a grip.

Claim 3

A swing-weight balance as defined in claim 1 wherein said means comprises a hole in said second upright section of a diameter greater than the diameter of the grip end of a golf club shaft but smaller than the diameter of the grip of a golf club at the butt end thereof, whereby a club without a grip on its shaft may be balanced to determine its swing weight by moving its shaft through said hole until it protrudes therethrough a predetermined amount which depends upon its length.

Claim 4

A swing-weight balance as defined in claim 2 wherein said second upright section includes an element extending therefrom in a direction away from said rigid member, said element having marks thereon for indicating the amount a shaft should protrude through said hole for a given shaft length.

Claim 5

A swing-weight balance as defined in claim 3 wherein said element is a fixed counterweight.

Claim 6

A swing-weight balance adapted to employ any substantially horizontal flat surface as a base comprising: an elongated rigid member consisting of a flat sheet of material having at least two longitudinal ridges and having a first upright section at one end thereof for supporting a golf club shaft, a second upright section at the other end with means for holding the grip end of said shaft, and an integral rocker between said upright sections extending from said rigid member in a direction opposite said upright sections for the purpose of resting on said flat surface while in use; a balancing weight adjustable in position on said two longitudinal ridges between said upright sections, said ridges extending in a direction away from said rocker to support said balancing weight away from a flat portion of said sheet between said ridges; and a graduated scale placed on said flat portion between said ridges of said elongated rigid member for indicating the swing weight of a golf club by the position of said balancing weight with respect thereto when its position is so adjusted that only said rocker rests upon said horizontal flat surface.

Claim 7

A swing-weight balance adapted to employ any substantially horizontal flat surface as a base comprising: an elongated rigid member consisting of a flat sheet of material having at least two longitudinal ridges and having a first upright section at one end thereof for supporting a golf club shaft, a second upright section at the other end with means for holding the grip end of said shaft, and an integral rocker between said upright sections extending from said rigid member in a direction opposite said upright sections for the purpose of resting on said flat surface while in use; a balancing weight adjustable in position on said two longitudinal ridges between said upright sections, said ridges extending in a direction away from said rocker to support said balancing weight away from a flat portion of said sheet between said ridges; and a graduated scale placed on said flat portion between said ridges of said elongated rigid member for indicating the swing weight of a golf club by the position of said balancing weight with respect thereto when its position is so adjusted that only said rocker rests upon said horizontal flat surface.

Claim 8

A swing-weight balance as defined in claim 5 wherein said integral rocker comprises a crimp on each edge of said sheet.

Claim 9

A swing-weight balance as defined in claim 6 wherein said crimp on each edge of said sheet supports said member a small fraction of an inch above said surface and is an arc which subtends a small angle of a circle that is large in diameter relative to said small fraction of an inch.

Claim 10

A swing-weight balance adapted to employ any substantially horizontal flat surface as a base comprising: an elongated rigid member having a first upright section at one end thereof for supporting a golf club shaft, a second upright section at the other end with means for holding the grip end of said shaft, and an integral rocker between said upright sections extending from said rigid member in a direction opposite said upright sections for the purpose of resting on said flat surface while in use; a balancing weight adjustable in position on said member between said upright sections; a graduated scale placed in a position on said member for indicating the swing weight of a golf club by the position of said balancing weight with respect thereto when its position is so adjusted that only said rocker rests upon said Horizontal flat surface; means for holding a club adjacent said first upright section with its shaft transverse the length of said rigid member; and a second integral rocker between said upright sections for weight balancing said club while measuring the static weight thereof by adjusting the position of said weight balance until only said second rocker rests upon said flat surface, said second rocker being placed between said upright sections such that upon so adjusting the position of said balancing weight, the static weight may be read from the same graduations of said scale, and said scale is provided with legends for major divisions of both said swing weight and said static weight, major divisions of said swing weight coinciding with major divisions of said static weight.

Claim 11

A swing-weight balance adapted to employ any substantially horizontal flat surface as a base comprising: an elongated rigid member having a first upright section at one end thereof for supporting a golf club shaft, a second upright section at the other end with means for holding the grip end of said shaft, and an integral rocker between said upright sections extending from said rigid member in a direction opposite said upright sections for the purpose of resting on said flat surface while in use; a balancing weight adjustable in position on said member between said upright sections; a graduated scale placed in a position on said member for indicating the swing weight of a golf club by the position of said balancing weight with respect thereto when its position is so adjusted that only said rocker rests upon said Horizontal flat surface; means for holding a club adjacent said first upright section with its shaft transverse the length of said rigid member; and a second integral rocker between said upright sections for weight balancing said club while measuring the static weight thereof by adjusting the position of said weight balance until only said second rocker rests upon said flat surface, said second rocker being placed between said upright sections such that upon so adjusting the position of said balancing weight, the static weight may be read from the same graduations of said scale, and said scale is provided with legends for major divisions of both said swing weight and said static weight, major divisions of said swing weight coinciding with major divisions of said static weight.

Claim 12

A swing-weight balance as defined in claim 8 wherein successive major divisions of said swing weight are identified by successive letters of the alphabet, and the same major divisions are identified in succession by a series of integers, each integer of the series being greater than the last by two.
