An indexing device comprises a rotatably driven input shaft; a globoidal cam having, for the purpose of outputting intermittently the rotation of the input shaft, a taper rib defining a cam face which has a disk-shaped end face gradually yielding to a helical face about the input shaft; an output shaft to which the rotation of the input shaft is transmitted so that the output shaft may rotate intermittently; an indexing disk provided on the output shaft and having supports protruding radially ou...

An indexing system made of a plurality of arranged index sheets, each provided with indicia such as a letter, color, or symbol on an extended area thereof and a plurality of holes so that when the sheets are arranged one on the other, a viewer can see the specific indicia through the holes.

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...

An indexing device wherein a rotary member which is supported by a support member such that the rotary member is rotatable about its axis and axially movable between a first position thereof and a second position thereof is rotated by a rotational drive mechanism having a one-way clutch, in increments of a predetermined angle, and wherein the rotary member is prevented by a stopper mechanism from being rotated past the predetermined angle due to inertia while being placed in the first position, ...

A long retracting sootblower for boiler cleaning of the type having a lance tube which is advanced into and out of a boiler and simultaneously rotated, and having one or more nozzles discharging a jet of blowing medium which trace helical paths. An indexing mechanism is provided to change the positioning of the helical paths traced by the nozzles between successive actuation cycles to minimize boiler erosion and mechanical stress caused by repeated blowing medium impact against surfaces within t...

The present invention comprises a mechanism for incrementally rotating a plotter carousel holding a plurality of pens around its perimeter. The rotational increments of the carousel are spaced to present any of the plurality of pens to a drawing arm on the plotter, or other graphics. A non-servo, non-stepper electric motor, such as a DC motor commonly used in slot cars, provides the rotational power to rotate the carousel. A control device switches the motor on or off with an output connected to...

There is disclosed a novel Indexing Hinge which rotates when a plunger is depressed and locks when the plunger is released.

An indexing device for use with a machine tool comprises a housing supporting a rotatable face plate. The face plate is connected to be driven by a drive unit which includes a motor. The drive unit can be detached from the housing and replaced the other way round where this is convenient in use of the device, for example to position the motor so that it will not come into contact with any part of the machine tool to which it is fitted.

An apparatus for drilling holes through batches of paper, the apparatus having a vertically movable drilling head, a movable table for supporting the batch of paper through which the holes are to be drilled at predetermined positions, and an indexing means incorporating elongate indexing members with holes or recesses provided therein corresponding to the positioning and spacing of the holes to be drilled, and a locating pin arrangement associated with and movable with the table and adapted for ...

An indexing drive has an actuator which reciprocates a ratchet arm along an arcuate path to cause an indexed rotation of rollers during one direction of movement of the ratchet arm which bear on a follower to produce an associated indexed rotation of the follower which may be communicated with a drive mechanism of apparatus to provide an indexed movement of the apparatus. Desirably, when the follower is not being rotated by the rollers, it is restrained from rotation in either direction to preve...
