Abstract
An armature winding machine having an indexing mechanism for indexing the armature. The indexing mechanism includes an indexing clutch driven by an electric motor. A gear drive connects the clutch to the holding structure for the armature. The indexing clutch has a control collar that is selectively engaged with a plurality of pawls operable to stop the control collar at predetermined precise rotational positions. The positions of the pawls relative to the control collar are individually adjustable on a support providing for selective adjustment of the indexing positions of the clutch.

An apparatus for indexing an armature comprising:
- a clutch mechanism, drive means for transmitting power to the clutch mechanism, means for holding an armature in a selected rotational position, power transmitting means drivably connecting the clutch mechanism to the means for holding the armature whereby operation of the clutch mechanism will rotate the armature to a selected position, said clutch mechanism having a control member which can be held in selected fixed positions to release the drive of the clutch mechanism to thereby hold the armature in selected positions, actuator means movable to a first position into engagement with the control member to hold the control member in selected fixed positions and movable to a second position out of engagement with the control member whereby the clutch mechanism transmits power from the drive means to the power transmitting means, support means for supporting the actuator means, said support means being movable to selected adjusted positions, and means for adjusting the position of the support means relative to the control member to adjust the location of the actuator means relative to the control member thereby adjusting the selected fixed position in which the control member is held.
An incremental rotation control apparatus comprising:
- a clutch mechanism having a power input member, a power output member, clutching means operable to drivably connect the input member with the output member, and a control member operable to control the operation of the clutching means, said control member being movable with the input member when the clutching means transmits power to the output member and held in a fixed position when the clutching means does not transmit power to the output member;
- actuator means engageable with the control member to hold the control member in a fixed position to thereby release the drive to the output member and releasable from the control member to allow the control member to move with the input member, support means for supporting the actuator means, said support means being movable to selected adjusted positions, and means for adjusting the position of the support means relative to the control member to adjust the location of the actuator means relative to the control member thereby adjusting the position in which the control member is held.
An incremental rotation control apparatus comprising:
- a clutch mechanism having a power input member, a power output member, clutching means operable to drivably connect the input member with the output member, and a control member operable to control the operation of the clutching means, said control member being movable with the input member when the clutching means transmits power to the output member and held in a fixed position when the clutching means does not transmit power to the output member;
- actuator means engageable with the control member to hold the control member in a fixed position to thereby release the drive to the output member, said actuator means including a plurality of pawls, at least one of said pawls having a radially inwardly directed tooth having a rear face engageable with the control member to hold the control member in a fixed position, the remainder of said pawls having forward faces selectively engageable with the control member to hold the control member in different fixed positions, means for adjusting the position of the actuator means relative to the control member to adjust the position in which the control member is held, and means for pivotally mounting the pawls on the means for adjusting the position of the actuator means.
An apparatus for indexing an armature comprising:
- a clutch mechanism, drive means for transmitting power to the clutch mechanism, means for holding an armature in a selected rotational position, power transmitting means drivably connecting the clutch mechanism to the means for holding the armature whereby operation of the clutch mechanism will rotate the armature to a selected position, said power transmitting means including a first gear connected to the cluch mechanism and a second gear connected to the means for holding an armature, and means drivably connecting the first gear with the second gear, said clutch mechanism having a control means operable to release the drive of the clutch mechanism to thereby hold the armature in a selected position, and means to release the control means whereby the clutch mechanism is engaged to transmit power to the power transmitting means which in turn rotates the armature until the clutch mechanism is released.
