Abstract: A castellated nut has 8 castellation slots in the outer wall. A circular locking insert has 25 long locking tabs radiating outwardly from the perimeter, an axle-engaging tongue protruding inwardly, and 9 smaller holding tabs which fit into an interior circular nut groove. All 25 locking tabs are bent at 90 degrees up from the circular locking insert and the axle slot-engaging tongue is bent down at 90 degrees. The locking insert is pressed into the nut and the small holding tabs are bent into the interior circular groove in the nut. The axle-engaging tongue is aligned with the axle shaft groove. The locking axle nut is threaded onto the axle shaft and tightened with the axle slot-engaging tongue sliding in the axle groove. One of the 25 locking tabs is bent into one of the 8 castellation slots.

Abstract: This invention relates to ball valves. One problem with conventional ball valves is that opening and closing the valve causes the valve seal to scrape across the valve seat. This reduces the life of the seal. This scraping problem can be eliminated by retracting the seal from the seat before turning the valve.In this invention, the ball valve has two coaxial handle assemblies. The outer, lever, assembly turns the valve closure member within its housing. The inner, handwheel, assembly is used independently to retract or extend the valve seal from or to the valve seat. The retraction or extension is achieved by use of a jack-screw shaft which pushes the seal in and out. The jack screw shaft is driven by a series of gears--a first bevel gear, a ring gear, and a second bevel gear--driven by the inner handle assembly. The ball valve is also provided with an inspection port. This port permits inspection, repair, or replacement of the valve seal while the valve is in use in its open position.

Abstract: A fluid line connector fitting is provided which has first and second generally tubular members, one end of the second member being slidably receivable within the first member. Releasable locking means are also provided to prevent withdrawal of the second member from the first member. The releasable locking means are releasable by the action of a release means which reacts to longitudinal movement of the second member toward the first member.

Abstract: In a valve of the ball or globe type operating means are provided to cause movement of the closure member in an angular mode about an axis of rotation and in a radial direction with respect to such axis in order that the closure member may be removed from the seat prior to subtantial angular movement. The operating means comprises two concentric stems one of which comprises an eccentric portion journalled with the closure member which eccentric portion provides the radial movement. The housing comprises an inspection port against which the closure member may be sealed while the valve remains open permitting inspection and replacement of the main seal through the inspection port while fluid continues to flow through the valve.

Abstract: A quick-release vice or work holder capable of rapid opening or closing and clamping, comprises a bed, a fixed jaw affixed to the bed and a movable jaw means. The bed has an inverted T-shaped central longitudinally-extending slot with at least one substantially vertical face having a plurality of recesses therein. The movable jaw has a guide means and a locking means. The guide means is slidably mounted on the bed for travel therealong. The locking means includes at least one pin adapted to move transversely of the slot to engage one of the recesses.
