A measurement tool for determining at least one of the loft angle or the lie angle of a golf club. The measurement tool includes a golf club head support structure having a mating surface and at least one beveled support element. The gauge also has a clamping tool capable securing the golf club head to the golf club head support structure. The clamping tool may include a pushing element and a mating element. The mating element has a jaw for applying a lateral force to the golf club head to secur...

A clubhead measuring gauge comprises a fixed base capable of rotating and adjusting its position along a circumference and fixing a protractor; an adjustable measuring base for mounting the protractor and allowing the protractor to shift its position in an increasing or decreasing angle; and an assistant measuring base having a standard side. All of the foregoing components are coupled to a base having a flat horizontal surface. By means of the protractor of the adjustable measuring base, the fa...

This invention is directed to a golf club head surveying instrument includes a bottom block, a quarter circle scale plate, an adjusting frame, a V-shaped block, a balance block, a slide block, and a rectangular block. The adjusting frame is fixed to the scale plate with its rear end, the V-shaped block is mounted on the adjusting frame and arranged to provide a clamping element for holding a golf club. An adjusting knob is provided with the scale plate for angular adjusting. The slide block is m...

A golf club measuring device has clamping means for retaining a head of a golf club in a fixed reference position and measuring means for measuring the loft and/or lie of the club. The clamping means comprise a first jaw for clamping a striking face of the club head against a first reference surface and a second jaw for clamping a sole of the club head against a second reference surface. The device is conveniently designed to be able to measure the loft and/or lie of both right- and left-handed ...

The device for determining the center of gravity of an object measures the moments of the object (e.g., golf club head, or other irregularly shaped object) as it is positioned in three mutually orthogonal axes. As the weight of the object is known, the moments may be divided by the weight to determine the precise arm from the scale to the center of gravity of the object. A line is marked across the exterior surface of the object along each orthogonal axis, with the intersection of the lines defi...

Embodiments of the present invention provide a fastener assembly that includes a grommet and a pin. The grommet may include a collar integrally formed with a plurality of legs, wherein an opening is formed through the collar. The pin is moveable through the opening between pre-driven and driven positions. The pin may include a plurality of flexible pin compression members connected to a ramp. The plurality of flexible pin compression members and the ramp spread the legs open in the driven positi...

A trailer hitch guide with a first portion to be mounted on a tractor vehicle, and a second portion to be mounted on a trailer vehicle. The first portion having a guide telescopically mounted to the tractor such that it can be viewed by the tractor operator while the vehicle is in motion. The second portion having a hood telescopically mounted to the trailer drawbar at a height equal to that of the guide. The relative spacial relation between the hood and guide emulating the relative spacial rel...

A gauge for accurately measuring depths of grooves formed in a face of a golf club head. The gauge includes a disk with a diameter of approximately one-half inch and a thickness of approximately one-eighth inch. The gauge also includes a ridge that extends across a flat surface on the disk. When the gauge is used, it is positioned so that the ridge is inserted in a groove in a club head face. If the ridge contacts the bottom of the groove, the disk will not lie flush against the club head face b...

This invention relates to a tool for aligning and manipulating an electrical outlet comprising: a base member including a top portion and bottom portion, front portion and rear portion, the rear portion including plugs for plugging into the electrical outlet; and a removable shield for minimizing the possibility of shorting out an electrical connection of the outlet with a metallic junction box during installation for example, the removable shield and the base member being coupled together or re...

The invention relates to an arrangement (1) for checking the quality of balls (2) in respect of their diameter (D) and any damage to their periphery (3), in particular intended for checking golf balls (2). A diameter gauge device (4) extending along at least part of the diameter (D) of an aforementioned ball is situated at a distance from a bottom support (5) so arranged as to support a ball (2) accommodated in the arrangement (1) for checking.
