The invention is a highly precise sight for archery. The invention uses a C-frame that is attached to the bow by a bar. Across the open area of the C a blade is attached. The blade contains a rack and along the blade runs a gauge on the rack. For an archer to sight he moves the gauge up and down the blade which moves the sight up and down. The archer can precisely measure to one thousandths of an inch from the gauge. Thus if an archer wishes to reposition his sight to the exact location within a thousandth of an inch all that is necessary is that he write down or remember the gauge readout. In one embodiment of the invention the gauge is analog. In another embodiment of the invention the gauge is digital. The sight also has a windage adjustment that can also be adjusted down to one thousandths of an inch. To get the accuracy down to one thousandth of an inch for this elevation and still manufacture the sight inexpensively, applicant used the parts from mass produced calipers. He takes a regular caliper with the jaws removed using only the blade and the gauge and places it in a c-shaped frame that attaches to the bow, and mounts the scope housing to the gauge of the caliper.

Bow sight

A spray gun carriage assembly is disclosed which provides rapid and accurate reciprocating vertical movement of a spray gun mounted on the assembly, with the stroke of the gun movement being readily adjustable. The spray gun carriage is also movable in two additional axes, i.e., in a horizontal plane. A horizontally extending boom is reciprocated vertically to move the spray gun up and down relative to a workpiece, such as a workpiece being conveyed past the carriage assembly. A first shock absorber mechanism dampens the moment of inertia of the boom, and a second shock absorber mechanism dampens the linear inertia associated with vertical movements of the boom, thus providing for quick and accurate spray gun movements and faster and more efficient spraying. A mechanism is further provided for pivoting spray guns mounted adjacent the end of the boom to yield still further adjustment of spray direction. A quick change flight bar facilitates rapid changeover of the spray guns used with the assembly. The flight bar has a mounting plate which is received on the pivoting mechanism, and has a shaft extending from the plate on which a plurality of spray guns are supported. Changeover from one set of spray guns to another is rapidly accomplished through the simple exchange of flight bars on the pivoting mechanism.
