Abstract: A golf club survey instrument includes a weight scale and a variably positionable fulcrum, enabling the instrument to be used determine the total weight of a golf club or the weight of each of its separate components, the swing weight of the club, and the center of gravity of the club. A linear scale also provides for the determination of the length of the club, or club components such as the shaft, grip, etc. The instrument comprises a base having a weight scale affixed at one end thereof, with the scale including a golf club grip retainer thereon positioned to place the end of the grip at the origin of the linear scale. The retainer also limits oscillations of the club, thereby providing for the rapid and accurate determination of the center of gravity of the club when balanced upon the fulcrum of the instrument. The base also includes a linear track therein and parallel to the linear scale, with the track providing for the adjustable positioning of the fulcrum therein.

Abstract: A simple, inexpensive weighing device having only one part which moves relative to the remainder of the device can be constructed utilizing a body shaped so that it will rock relative to a supporting surface when an object is placed in a holder forming a part of the body. A pendulum type pointer is pivotally mounted on the body so that the approximate weight of the object can be determined by visual inspection of the position of the pointer relative to appropriate indicia on the body. The body is shaped so that the amount that it will rotate when an object is placed upon a holder is limited to such an extent that the horizontal distance between the object and the center of rotation of the pendulum does not change significantly so as to achieve a desired degree of accuracy in the weight indicated by the position of the pendulum.
