In a device for indexing a work attached to a cutting device of a machine center, the device for indexing comprises an indexing plate connected to a driving shaft of an indexing table and held by a stopper on the normal position on a base, a push bar interlocking operatively with an extra action other than the normal action of a tool to move linearly relative to the base, an actuating member for rotating the indexing plate by engaging the push bar operatively. The device is so constructed to dis...

The turret comprises a supporting base and an indexing head mounted on the base for extension and retraction away from and toward the base and for rotation with respect to the base. A first rotary actuator is mounted on the base and threadedly carries a lift stud which is rotatably connected to the head. A series of interengaging indexing lock members hold the head in one of several indexed positions when the head is retracted. When it is extended, the lock members disengage to allow the head to...

Apparatus for successively indexing slots of a wafer carrier into position at an end of a conveying means, such as an air slide, utilizes motion of a rotary drive means to move pins within drive slots and impart motion to the carrier. As the rotary drive head rotates, a pin moves down into a drive slot, pushes against a sidewall of the slot to move the carrier, then retracts back to the end of the slot. With proper positioning of the rotary drive means, the pins also serve to prevent extraneous ...

An indexing mechanism for converting reciprocating motion into intermittent rotary or linear motion. Driving elements engage driven elements during each motion of the reciprocating member in either direction to effect intermittent motion of the workpiece in the desired location. The driving elements also include locking means to limit the motion imparted by the reciprocating member and lock the driven elements in place until the reciprocating member moves in the opposite direction. Several diffe...

The indexing stacker is composed of four compartments which are defined by three vertical side walls and a bottom wall which is inclined towards the center of the stacker in the X and Z planes. The bottom wall has a substantial cut-out exposed on the open side of the compartment which allows insertion of fingers under a stack of articles to facilitate removal of same. A post is mounted in the cut-out region to provide support for the stack of articles. Means are provided for indexing the stacker...

An indexing mechanism that converts reciprocal movement into rotary movement and that includes a driver member supported for movement along a straight line between a first position and a second position. A driven member in the form of a sleeve encircles the driver member and has a series of circumferentially spaced identical helical grooves formed in the inner surface thereof. Each pair of adjacent helical grooves have a straight tapered groove connecting one end of one helical groove to the oth...

Apparatus for selective electroplating of discreet areas of strips intermittently advanced through said apparatus. A particularly important aspect of the apparatus is the means whereby the strip is advanced intermittently but is, at all times, held under tension by a dual-clutch arrangement comprising two indexing wheels, a drag clutch positioned to control tension on a first wheel at one side of the electroplating bath, and another indexing wheel intermittently operated to advance the strip on ...

An indexing device for indexing a member, such as a table, into operative working positions in which the table carries follower elements, such as rollers, and cooperating therewith is a drive member mounted on a pair of parallel equal length arms which rotate in unison thereby causing the drive member to take an orbital path. The drive member is slotted and during travel along the orbital path picks up one of the followers on the table and therethrough causes the table to carry out an indexing m...

An indexing head has a plurality of co-axial discs rotatable relative to each other. A first disc carries an indexing pin receivable in a series of equi-angularly spaced recesses of a second disc. A third disc is angularly settable relative to the second disc by means of gauge blocks, and is lockable after setting by locking means. A tool shank can be releasably held in an axial bore of the first disc. When used in an oil bath of an erosion machine, the head is fitted with a bellows skirt to pre...

An indexing device consists of a base, a lid pivoted to the base, and a plurality of cards pivotally mounted between the lid and the base for selective movement with the lid. Each card has a lug at a front edge thereof, the plurality of cards being arranged such that the lugs are serially positioned at specific intervals in step-wise fashion. A like plurality of levers are pivoted to the base at corresponding specific intervals. A first end of each lever has a push-button fixed thereto for downw...
