Abstract: A rolling gear apparatus for an involute tooth gear cutting machine that rests on an engine bed of the machine. A primary carriage is longitudinally movable in both directions on the engine bed and carries at its top a secondary carriage that is guided in longitudinal movement in both directions. A crank element is connected to the secondary carriage and is glidingly movable in a guideway that is angularly adjustable relative to the engine bed. A roll-circle member is carried by the primary carriage and is connected to the secondary carriage through a band drive. The movement path II of the secondary carriage is at an oblique angle to the movement path I of the primary carriage to provide improved selectivity in adjusting the base-circle diameter of a toothed-wheel gear blank connected to the roll-circle member.

Abstract: There is disclosed and shown an automatic nut installation and torquing system (10) connected with an automatic fastener installation machine (11) whereby a threaded nut (21) is automatically conveyed in proper orientation from a supply source to a final installed position on a threaded fastener (34); the installed nut (21) being at a selectively predetermined final torque value that is selectively variably and controllable without regard to the torque output of the torque motor (48) so long as the desired installed torque value of the nut (21) does not exceed the maximum torque deliverable by the torque motor (48). The variability and controllability of installed torque is accomplishable without any recalibration or readjustment of torque motor (48) to change its torque output.

Abstract: A hand held tool for installing compression rings includes a pair of relatively reciprocable coaxial cylindrical independently spring biased elements housed within a cylindrical handle which includes mode control means automatically preconditioned for enabling the tool to perform either an installation or ejection operation. The mode control means includes a cylindrical radial cavity containing plural spring biased spherical ball detents and extends into corresponding portion of the outer reciprocable element. The positioning of a tapered central section of the inner reciprocable element coincides with the cavity so that one of the spherical ball detents normally sits within a hollow defined by the taper. When one spherical ball detent, in response to the mode control means being preconditioned by depressing a front end or shaft portion of the inner element, is positioned to lock the outer member to the handle, this allows the ring to be installed onto the cam shaped front end of the outer element.

Abstract: In grinding non-uniform workpieces rotating about a longitudinal axis an endless abrasive belt passes over a contact roll in tangent contact. The rotating workpiece is pressed against the belt at the tangent point and the belt is passed around the workpiece on at least one side from the contact point. The amount of wrap is sufficient to heat the workpiece relatively uniform. Either plunge or traverse grinding may be used.

Abstract: A ratchet reversing mechanism of the shifting pawl type is operated by a reversing apparatus which is confined to a small arcuate segment of the work-turning member, leaving space over the work-turning member for a quick-release mechanism and for attachment of a speeder ring. A switching ring lies over the pawl and includes a spring-receiving recess which positions a compression spring in a radial plane above the pawl, one end of the spring engaging the pawl and the other end of the spring engaging the switching ring at a location radially outwardly of the engagement with the pawl, such that the spring extends only over the segment of the work-turning member defined by the recess in the work-turning member which receives the pawl. A second pawl is provided in another embodiment of the invention.
