Abstract: The invention relates to a method of making what may for convenience be regarded as friction joints--that is to say, joints between the touching surfaces of two parts that are held in contact (by a force as experienced in a light interference, not one sufficient to cause forging) and that would otherwise move laterally past one another parallel to the touching plane, the method involving some minimal initial lateral movement of the two surfaces sufficient to cause some asperity deformation, leading to welding and shearing under special conditions--the phenomenon of "galling"--but not sufficient to raise the bulk temperature of either to a level where bulk welding will occur.

Abstract: A piece of movable equipment is provided with a male docking bar (10) . An immovable piece of equipment is mounted to an immovable fixture which has a female docking bar (28). The female docking bar (28) has freedom to move in a first axis. The movable piece of equipment is brought into contact along a second, orthogonal axis to meet the immovable piece of equipment, at which point lugs (12) on the male docking bar mate with corresponding holes (30) on the female docking bar. The male locking bar can then be interlocked (16, 32) to the female docking bar. The movable piece of equipment can then further be moved along the first axis.

Abstract: The invention relates to a coupling for fixedly, i.e. non-flexibly, connect free ends of two shaft together. The connection is releasable. A typical field of application is in pumps.

All parts are made free of play when they are secured to the shafts. The invention facilitates maintenance work, e.g. in replacement of packing rings in a pump. It also facilitates the manufacture of the coupling.

Abstract: A detachable locking device is described which consists of a pair of standard box end wrenches with shortened handles having integral ears on the ends of the handles with openings therethrough.

Abstract: A quick change gear apparatus provides a system which shortens time of spindle machine gear changes to approximately ten percent of that previously required for gear change operations. In a preferred form, the apparatus includes a cylindrical spacer juxtaposed against a face of a gear which is secured between the spacer and a shoulder on a gear shaft. A split washer is also employed to permit the quick change operation by virtue of the loosening of a cap screw secured in a free end of the gear shaft. The cap screw contains a head which retains the split washer and assures that the split washer is urged axially against the spacer and gear members on the shaft. A partial turn of the cap screw will enable radial removal of the split washer, to thereby permit subsequent axial removals of the spacer and gear.

The ball-and-socket joint has a ball head, a CIRCLIP and an outer structural part forming a socket, in which there is a circumferential groove the bottom of which forms a support face for the circlip. The support face is substantially defined by a hollow cone and surrounds the CIRCLIP like a jacket, and a flare angle of the support face opens toward the center of the ball head. The CIRCLIP presses with radial bias against the support face and therefore migrates in the direction of its largest diameter and hence toward the center of the ball head until it rests thereon.

Abstract: The pinion gear of a gear pump is press fit onto the end portion of the drive shaft of the pump and is positively captivated on the shaft by a key and by a hot upsetting process, the latter resulting in the formation of axially protruding burrs on the end face of the shaft. When the drive shaft is rammed forwardly with significant force, the burrs tend to embed in an end plate disposed in opposing relation with the shaft. To prevent the burrs from embedding in the end plate and locking the shaft against rotation, the end plate is formed with a recess which receives the burrs with substantial axial clearance when the shaft is rammed forwardly against the end plate.
