An apparatus capable of measuring pin protrusion and collar swage height in a fastener assembly. The apparatus comprises: a gage body; a shaft that is translatable along its axis; an instrument that measures the absolute axial position of the shaft relative to a zero position; pin protrusion and collar swage height measurement contact members coupled to the shaft; and a slotted gage plug that is rotatable and axially displaceable relative to the gage body. The gage plug sits on the swaged collar during measurements. When the collar swage height measurement contact member is disposed in the slot in the gage plug, pin protrusion can be measured. When the collar swage height measurement contact member is not disposed in the slot and instead rests on top of the gage plug, the collar swage height can be measured.

Dual-function gage for measuring dimensions of a fastener assembly

An aqueous tube cleaning system as described herein can be utilized to clean a plurality of tubes having different lengths. The system includes a tower assembly having a wash chamber that houses the tubes during the cleaning cycle. The tower assembly is held in a horizontal load/unload position for loading and unloading of the tubes. The system rotates the tower assembly into a vertical cleaning orientation to accommodate cleaning with cleaning and rinse solutions, which flow through and around the tubes using the force of gravity. After rinsing and draining, the tower assembly is rotated back to the horizontal position for unloading.

Cellular aqueous tube cleaning system and method

An aqueous tube cleaning apparatus and method includes a cleaning receptacle and a vertical receptacle, which is taller than the cleaning receptacle. A tube, or bundle of tubes, is placed in the cleaning receptacle, extending through an inlet port from the vertical receptacle, and a gate is closed to clamp the tubes in place. The vertical receptacle is then filled with a fluid, and the pressure created by gravity forces the fluid through and around the tubes, cleansing the inner and outer surfaces of the tubes.

An embodiment of a hole angularity gage includes a gage body and a contact disc positioned within the gage body. The contact disc includes a central opening defined by an inner edge. The gage also includes a center pin that extends through the central opening, and a hole probe adapted to rotate the center pin from a primary gage axis toward the contact disc's inner edge. The gage also includes an indicator adapted to activate when the center pin makes contact with the contact disc. Another embodiment of a hole angularity gage includes a hole probe and a circuit. The circuit includes an indicator and a switch, which is adapted to close when the hole probe is rotated by an angle greater than a gage setting angle. The indicator is adapted to activate when the switch is closed. Other embodiments include methods for using and manufacturing hole angularity gages.

Hole angularity gage and methods of operation and manufacture therefor

A measurement device and apparatus for measuring the out-of-roundness of a circular part. The apparatus includes a base on which a travel assembly is mounted within an elongated channel formed in the base. A recirculating ball bearing slide assembly is operatively coupled to a flat strip force spring, which is in turn coupled to ball bearing slide assembly, and which provides a constant contact force, regardless of distance, to bias the travel assembly into a 90-degree corner portion of the base assembly. A generally circular part is placed in the 90-degree corner and manually rotated while the travel assembly is in contact with an outer surface thereof. The linear movement of the travel assembly is detected by a measurement device which provides an indication of the out-of-roundness of the part.

Apparatus and method for measuring circularity of circular parts

A device for supporting a long cable to permit the ends of the cable, such as swaged end fittings, to be tested by a conventional tension/compression tester. The device includes a drum upon which the cable is wound. The drum is supported by a pair of vertical flanges which in turn are connected to a movable platform of the tension/compression tester. One end of the cable is connected to a fixed base of the tester. A small section of the remaining portion of the cable that is not wound around the drum is engaged by a movable clamp which is fastened to one of the vertical flanges. The cable is tested by movement of the platform away from the base until a predetermined load is reached. A majority of the applied force is absorbed by the portion of the cable that is wound on the drum. The remainder of the applied force is absorbed by the adjustable clamp. Consequently, during the test there is limited slippage of the cable on the drum.
