Abstract: An intrinsic gauging device for a ferrule type tube fitting of the type having a coupling nut, a coupling body and at least one ferrule, includes a precisely formed marking on the coupling body that is visually perceptible when the coupling is in a finger tight position, and that is covered or visually imperceptible or otherwise has a predetermined relationship with the coupling nut when the fitting has been initially pulled-up. In a preferred form, the marking is realized as a precision groove or recess machined into a surface of the coupling body. The groove can be made more easily visually perceptible such as by roughening or knurling the surface, or coloring the surface, for example. The groove defines an edge at a precise position that corresponds to a predetermined axial displacement of the nut relative to the body for initial pull-up.

Abstract: A tool for inspecting and verifying weld beads in a pipeline includes a plate-like structure which has a surface and edges adapted for inspecting and verifying various weld bead attributes. The surface is imprinted with several identification marks, including for example, wall thicknesses and ratios of weld bead width to wall thickness. The tool can be used to verify weld bead convexity, weld bead concavity, and weld bead width for many different wall thicknesses. The tool is capable of verifying weld bead width and axial alignment of successive sections of pipe along the pipeline. All verifications and measurements are visual and tactile, without need for complex machinery or calculations, and can be accomplished with a single, lightweight tool. Additionally, a single tool can be used to verify weld beads for a variety of different pipe thicknesses.

Abstract: A molded limit gauge for measuring workpiece thicknesses. The limit gauge includes a body having one or more elongate ridges extending longitudinally therealong. Each ridge has a plurality of notches extending laterally through its upper portion. Each notch has a unique longitudinal dimension that is uniform. In a first preferred embodiment of the invention, the bottom surface of each notch and the land between each notch is horizontally flat. In a second preferred embodiment, each of these surfaces has a configuration of a laterally convex curve. The limit gauge body is configured such that it can be mounted atop a planing machine. So mounted, it can function as a structural top of the planing machine. Measurement of a board thickness is accomplished by attempting to slide the board through notches that appear to match its thickness. A range of board thickness is defined between the indicated sizes of two adjacent notches that respectively allow and do not allow passage of the board through.

Abstract: A pipe size measuring tool having a plurality of gauges, each gauge having an open mouth therein. The sizes of the open mouths in each gauge are different from each other. The gauges are mounted together with each gauge having a front end, a body portion and a rear end. The gauges are pivotally mounted together adjacent their rear ends so that they are moveable from a folded compact position to an open position. The front ends are wider than the rear ends and the gauges are thin and light-weight. Openings are provided in the rear ends so that the gauges may be pivotally mounted together at the rear ends. The gauges are of different sizes with the larger open mounts located in the larger gauges.

Abstract: An apparatus holds a feeler gage. The apparatus includes a shaft having an end to which the feeler gage is attached. A fixture aligns the shaft with an opening into which the feeler gage is inserted. The opening may be a gap of a connector. A portion of the shaft is a measuring section having a plurality of markers. The markers are stripes, grooves, or lands on a portion of the shaft. The fixture comprises a channel, sleeve or bearing that guides the shaft onto the fixture. The fixture includes a ridge for insertion of the fixture onto a track. The fixture may have an alignment arm that engages a side surface of the connector. The fixture has a latch that attaches the fixture to the track. The latch of the fixture comprises two substantially parallel elongate members separated by a distance approximately equal to a width of the track.

Abstract: A spacing tool is adapted for use with a conveyor that conveys plastic bottle containers of the type having a neck ring, a neck below the neck ring, and a body below the neck. The conveyor has a pair of support flanges that are spaced laterally from one another by a distance smaller than an outer diameter dimension of each container neck ring, but larger than an outer diameter dimension of each container neck. Thus, each container can be supported between the flanges with its neck ring in engagement with upper surfaces of the flanges. The conveyor has a pair of container guide rails that are spaced from one another by a distance larger than an outer diameter dimension of each container body so that each container can move along the conveyor between the guide rails. The spacing tool comprises a spacing member having a head portion, a neck portion below the head portion, and a spacing block below the neck portion. The head portion has a first outer diameter dimension larger than the spacing between the flanges.

Abstract: The present invention relates to a thickness gauge which comprises a plurality of metallic sheets made to have standard thickness, a U-shaped frame and a screw which adjusts tightness of the metallic sheets. The present invention is characterized in that each metallic sheet comprises a hole and that the hole positions of any two neighboring metallic sheets are different; when two or more pieces of metallic sheets overlap, the holes of the metallic sheets will be shielded by other metallic sheet and human eyes can not see through the holes. In another preferred embodiment, the thickness gauge is characterized in that there is a cut at each metallic sheet. Whereby users can distinguish clearly and conveniently one metallic sheet from several metallic sheets overlapping together and could avoid misuse and measurement errors.
