    摘要： A fixture for indexing a work piece, a machine spindle, or the like permits indexing a single rotation of the work piece or other mechanism in any integral number of equal divisions. Stops for the divisions are made to suit the job by assembling a standard roller chain with as many pins and pin spaces as there are to be divisions and mounting the chain about a tapered body, preferably a cone. Fixtures hold the chain at the plane in which the periphery of the cone is the right diameter to receive the chain and other parts adjust the indexing stop to overlie the roller chain at that plane. Adjustments are provided to adjust the indexing stop peripherally of the cone a short distance in order to bring the indexing stop to the required rotational position. This adjustment may also be used to adjust the rotatable part a fraction of an indexing stop.

    摘要： An indexer comprising a housing having an indexing spindle journalled therein in preloaded bearings and adapted to mount thereon a work holding chuck or fixture, the spindle having the radially inner portion of an axially flexible disc brake element or diaphragm affixed thereto, and the housing having a fluid pressure actuated ring non-rotatably but axially movable secured to the housing which axially flexes the radially outer portion of the disc into frictional engagement between the ring and said housing thus to securely lock the spindle in each of its indexed positions to prevent imposition of radial load on the spindle bearings and torque load on the locking pin of the indexing mechanism during the machining of a workpiece held by the chuck or fixture. The indexer herein is further characterized in the provision of a sealing ring in the chamber between preloaded spindle bearings, said sealing ring having an axial passage therethrough which intercommunicates the bearing chambers with a source of lubricant and having a radial passage for conducting fluid under pressure from the housing to the spindle for operation of a fluid pressure operated chuck on the spindle.

    摘要： In the lathe turret construction disclosed herein, indexing of the turret to bring successive tools into operating position is accomplished by a separate locking member which is axially slidable, relative to the turret spindle, between a locking position and a release position. The separate locking member includes means for preventing rotation with respect to a fixed frame of reference, independent of the member in which the turret spindle is journaled.

    摘要： A machine tool wherein the tool turret is indexible about a shaft and is shiftable axially to move the teeth of a ring gear thereon into and out of mesh with the teeth of a stationary ring gear. The indexing mechanism for the tool turret has a pinion which is coaxial with the turret and can be connected thereto by means of a disengageable clutch. The pinion is in permanent mesh with a reciprocable fluid-operated rack. When the clutch is engaged and the ring gears are disconnected, the rack can index the turret by way of the pinion and clutch. When the clutch is disengaged, the rack can return to its starting position without indexing of the turret because the pinion is free to rotate with reference to the turret.
