Abstract: A multiple-spindle mechanism employs an arrangement of passages, grooves, and ducts that promotes continuous and simultaneous lubrication of all spindles. The mechanism is especially well suited for use in an automatic screw machine.

Abstract: The system includes a protective sleeve that is lowered over a flag under the weight of a carrier ring. An arrangement of cables and control means effects raising and lowering of the protective sleeve, and positions the lowered carrier in a tilted orientation to effectively close the lower end of the sleeve and thereby to afford enhanced protection for the contained flag.

Abstract: A fast-acting die head that is particularly well-suited for use with small-size workpieces employs a set of chasers, each formed as a single piece and having a nose portion that provides two force-receiving surface elements. One of the surface elements is disposed to coact with a camming ring, which is moved axially thereover to close the chasers radially upon the workpiece; the other, underlying surface element receives the force of a spring-loaded plunger, which acts to thrust the associated chaser to an open position when the closing force of the camming ring is removed.

Abstract: A collet-operating mechanism utilizes an array of wedge members for the transmission of closing force to the pressure collar. The wedge members are of flatted barrel-shaped configuration to optimally cooperate, in line contact relationships, with bearing surfaces on the pressure collar and the supporting sleeve member.

Abstract: A filter unit of an automatic screw machine employs a filter element that rotates relative to, and in contact with, a brush element. Foreign matter is thereby automatically dislodged and ejected from the filter element.

Abstract: A system for washing parts utilizing a circulated, heated liquid includes a master unit and at least one auxiliary unit. The master unit has a tank for heating the washing liquid, and has a pump for circulating the liquid through the chamber of the enclosure. The auxiliary unit is devoid of such a tank, but has means for making connections necessary to enable circulation of the liquid heated in the tank of the master unit through the chamber of the auxiliary unit enclosure.

Abstract: The method, apparatus and system utilize the saddle on which the stationary head of an automatic screw machine is normally mounted, for supporting a cylindrical boring bar. Rotation and advancement of the bar on the saddle surface enables reboring of the cylindrical opening through the rotary head-mounting section of the machine, which rebored opening will be precisely coaxial with the surface of the saddle.

Abstract: A multiple-spindle mechanism is lubricated, and is protected against the entry of foreign matter, by a mist of oil which is distributed under pressure between mutually contacting bearing surfaces, and is discharged outwardly thereof. The mechanism is especially well suited for use in an automatic screw machine, and provides the desired functions despite the axial reciprocation of the spindles that occurs therein.
