An feeding and indexing apparatus has article feed units which can start and stop along a circular path at specific time intervals when drive arms are rotated at a constant speed. A cam assembly is disposed radially inwardly of and concentrically with the circular path, and cam followers are movable in contact with the cam assembly. The drive arms are rotatable about the center of the cam assembly. Driven arms are operatively coupled to the drive arms, respectively, at respective junction points...

In a turret indexing device, a coupling containing three gear members is employed in a turret indexing device to cooperate with an indexing disc mounted on an output shaft which is adapted to hold an indexing head. The coupling is operated by a first cam fixedly mounted on an input shaft through a lever mechanism, and the indexing disc is driven by a second cam fixedly mounted on the same input shaft. The three gear members include a first gear member fixedly mounted on a collar slidably mounted...

An improved apparatus for placing current on a moving wire electrode traveling between two points and over a conductive member in the form of a rod. The rod is at an acute angle with respect to the normal straight line of wire travel and its circular outer surface is in contact with the moving wire. The improved apparatus provides a mechanism whereby the conductive member is turned about its longitudinal axis thereby exposing a plurality of different contact surfaces to the wire. An index mechan...

An ammunition indexing mechanism for moving, responsive to actuation of a trigger mechanism, a cartridge from a selected one of a pair of opposed feedports in a weapon receiver and into alignment with a firing chamber of a barrel assembly of the weapon, has a rotary mechanism for moving through a selected index angle each ammunition cartridge entering through the selected feedport; and a torque assembly for storing energy, responsive to a selected movement of the barrel assembly, until released ...

An improved magazine for fragile projectiles such as pellets or paint balls, wherein the front end of a rotating drive member is formed with elongated fingers to form individual chambers to feed the projectiles one by one out of the magazine synchronously with the firing of the gun. An escapement member operated by some portion of the gun permits rotation of the carrier within the housing of the magazine, one projectile distance at time, to cooperate with the elongated fingers and an exit ramp f...

A retrofit auto-indexing system for a turret punch press is described in which a predetermined location is provided to which both the upper and lower turrets of a non-indexing turret punch press are rotated. Upper and lower punching tools are mounted respectively in the upper and lower turrets in such a manner so as to be rotated simultaneously, using a single servomotor, to a desired angle. The auto-indexing system is controlled using a microcomputer which is connected to receive the numerical ...

The present invention relates to an indexing and organizing system for audio/video tapes and compact/video discs. The system providing self adhesive labels and flags comprising sheets of thin semi-rigid flexible material. Each label having an adhesive applied to a back portion thereof. Each label has three panels to embrace a front portion, side portion and back portion of a storage case for a video/audio tape or video/compact disc whereby when a self adhesive label is attached to a storage case...

A self-contained shoulder indexing apparatus is for use during imaging of a shoulder joint of a patient, with the patient lying on an imaging table slidable into and out of a primary imaging coil. The self-contained shoulder indexing apparatus includes an index mechanism having an index member lockable in any selected one of a plurality of sequential index positions. Table attachment means connects the index mechanism with the table for sliding movement with the table. A cuff support member is c...

Apparatus and method for indexing sheets cut from a web including a production line having an unwind at one end and a backstop at the other end, a printer and a rotary knife between the ends, the relation of the knife speed to the web speed being changed cyclically to develop longer and shorter sheets.

An attachment indexing apparatus which performs the steps of indicating an objective indexing position angle of an attachment by an indexing position angle indicating means 1, detecting the present position angle by a position detecting means 2, comparing the objective indexing position angle with the present position angle by an angle comparing means 3, determining the indexing rotation direction of the attachment by an indexing rotation direction determining means 4 in accordance with the comp...
