Abstract:
A gage according to the present invention for use in measuring engagement parts of a pneumatic hose coupler and including a body and a spring loaded contact rotatably mounted to the body. The body includes an alignment part for locating the gage on the coupler and a member for contacting one of the engagement parts. The contact is biased into contact with another of the engagement parts and calibrated indicator marks provide a visual indication of the angular distance between the two parts. Sights through the gage measure another angular dimension between coupler engagement parts. The gage also includes a plug part for measuring vertical clearance between other parts of the coupler.
Abstract:
A metric and English measuring gauge including parallel first and second bar members having mutually engaging side faces and including contact end portions for engagement with tubular members wherein the offset of such tubular members will be indicated by the relative longitudinal position of the bar members. A shoulder retaining part is enclosed around the bar members and has windows on opposite sides for observing metric and English scales imprinted un opposite sides of the bar members for measuring wall thickness.
Abstract:
A method of forming undulate protrusions on a split ring with the ring placed in a die to first form a center protrusion and then to form the other protrusions located between the first formed protrusion and the ring ends.
Abstract:
A gage including parallel first and second bar members having mutually engaging side faces and including contact end portions for engagement with structural members wherein the offset of such structural members will be indicated by the relative longitudinal position of the bar members. One of the bar members includes a bore having a pin therein which can be made to protrude a selected distance from the end face of the bar to indicate the depth of a bore as measured from the bar end face.
Abstract:
A gauge for measuring the dimensions of a fillet weld. The gauge includes a calibration arm which slides within diagonal slots formed in the gauge body. The arm overlies a scale imprinted upon the gauge body.
Abstract:
A split ring pipe spacer used to separate a pipe from the fitting shoulder during welding. The spacer has yieldable protrusions for the purpose of maintaining proper spacing and alignment of the pipe and fitting during welding.
Abstract:
A split, ring-shaped pipe spacer used to maintain separation between a pipe and a fitting shoulder during welding. The spacer has pairs of yieldable offset segments. The two segments of each pair bulge from the spacer body in opposite directions to maintain proper spacing between the pipe and fitting during welding. The opposing offset segments also permit bi-directional insertion of the spacer into the fitting, position the spacer body out of contact with both the pipe and the fitting, and minute and distribute the stress imparted to the spacer when forming the segments during manufacturing. The spacer ends forming the split in the spacer have a tongue-in-groove shape to accommodate circumferential expansion of the spacer under compression of the pipe.

Abstract:
A fixture for aligning clamping pipes end to end to enable joining the pipes by welding includes a collar circumscribing one of the pipes and circumferentially spaced arms extending outwardly from the collar and then coaxially with the pipes. Pipe damps are supported by each of the arms at approximately 120 degrees intervals about the pipe. The stems of the clamps are supported by the arms such that proper orientation of the clamping shoes and guide members is assured. Furthermore, an extension of the stem which projects between the pipes and carries an inner guide member for engagement with the inner circumferential surface of the pipe has a differential thickness such that the pipes are initially separated by a predetermined thickness by engagement of the pipes with the necked portion of the extension for tack welding. After tack welding is complete, the stems are rotated 90 degrees, thereby bringing a narrower dimension of the necked portion into registry with the gap between the pipes, permitting withdrawal of the stems.
Abstract:
A wafer-shaped spacer ring for a pipe and fitting. The ring is formed of liquid soluble material to allow the ring to dissolve after the pipe and fitting are welded and the pipe is flushed.
