Abstract:
This invention relates to gauges and more particularly to size ring gauges for gauging threaded pipes, casing ends and the like and has for its object the provision of novel form of gauge of this class that can be quickly fitted to and taken from the threaded article without the necessity of threading ii into place as heretofore Heretofore a gauge coupling or ring has been used for gauging threaded articles like pipe and casing ends, and it has been necessary to screw or thread the gauge coupling along the whole threaded 'end by hand with the aid of a suitable wrench. About eight turns are necessary to thread the gauge coupling on pipe ends, and about sixteen turns are necessary to thread the gauge coupling on casing ends. This operation consumes so much time and requires so much hard labor that one man can only gauge from 160 to 180 ends in a turn of ten hours. In order to insure threads within a tolerance of one turn on pipe and one and one-half turns on casing, it is necessary or at least desirable, to gauge every end, and to do this with the size or gauge couplings heretofore used required a large force of sizers and entailed a considerable labor cost.
Claim:
A size ring gauge for gauging pipe and casing ends, comprising a ringlike easing a segment ring mounted in and revolvably movable relative to said casing, segments mounted in said segment ring and movable diametrically thereof, spring means for normally tending to move said segments outwardly, and cam means in said casing adapted to force said segments inwardly when relative movement is had between said casing and segment ring in one direction and to release said segments for outward movement when relative movement is had between said easing and segment ring in the other direction. |
