  • Patent number: 4841831
    Abstract: A reloader for reloading cartridges. A reciprocating plunger carries a turret that rotates around the axis of the plunger. The turret carries a plurality of cartridges for reloading, the cartridges being symmetrically spaced around the turret axis and adapted to be indexed around the axis in a step-by-step sequence. An overhead die holder contains a plurality of dies spaced in a symmetrical pattern similar to that of the cartridges but in fixed positions. A center opening in the die holder houses a rotatable bushing. The rotation of the bushing is controlled in part by a one-way clutch. An indexing shaft affixed to the turret extends from the turret axis through the bushing. The shaft has a multi-sided cross section and is slidably fitted to the bushing in a manner that prevents relative rotation. The configured cross section has an axial twist and when forced through the bushing by the reciprocating plunger, causes turning of one or the other of the shaft and turret or the bushing.

  • Patent number: 4805497
    Abstract: An externally indexable turret-like device is provided, for use particularly with a lathe, screw machine, automatic machining center or the like, in which the indexable turret-like device cooperates with an external index member mounted on the machine to effect tool-indexing movements. In a principal illustrated embodiment, the index member is fixed to the headstock of the turning machine. The indexable turret is mounted on the tool-holding slide, which is movable by numerically controlled motors or the like. When indexing is desired, the tool support is moved to and into pressure contact with the fixed index member, which mechanically actuates the device through one index position. The device is then returned, by means of the programmed numerical control arrangement, to a cutting position.

  • Patent number: 4286483
    Abstract: The invention comprises a tool turret for a turning machine whose operational axis has a wider spacing from the bed of the carriage than the spindle axis of the turning machine. The tool turret has an inner rim with inner turning tools and an outer rim with outer turning tools, the inner and outer turning tools being angularly offset in relation to each other. In order to bring the inner and outer turning tools into operating position during the stepwise further movement of the turret, successive operational angles must be variable. Because of the wider spacing of the operational axis from the bed of the carriage, the turret disc carrying the tools can be made larger with the result that more tools can be provided thereon or the spacing between the tools can be enlarged. The changeover with unequal angles can be accomplished by means of a regulated direct current motor, the operational angle being fed into the regulation circuit as the desired value.

  • Patent number: 4234023
    Abstract: A liquid feeder comprises a liquid suction and delivery pump which withdraws a liquid such as a culture solution, buffer solution, enzyme solution or the like which is retained in a liquid storage container as refrigerated or at a reduced temperature and delivers it through a flexible tube for injection into a culture vessel located within an incubator. The tube is inserted into an inner pipe and is sealingly secured thereto. The inner pipe is detachably and hermetically mounted in an outer pipe which extends through and is secured to a wall forming an environment isolating layer of the incubator. An eccentric crankpin which is driven by a motor is connected through a link with another crankpin having a greater eccentricity, the latter crankpin being driven for rotation to cause a reciprocatory rotating motion of a driven shaft about its own axis through an angular extent of less than 180.degree..

  • Patent number: 4189963
    Abstract: An index apparatus for indexing a rotary table rotatably and vertically slidably received within a base, comprises a pair of coupling members secured to the rotary table and the base, respectively, and engageable with each other. The rotary table is lifted and lowered by a hydraulic actuator. The rotary table is rotated by a drive means including a drive motor. Generating means are provided to generate a signal each time the rotary table is rotated a unit angle. Control means are provided to reduce the rotational speed of the rotary table in response to the number of signals generated from the generating means, when the rotary table is rotated to a position spaced a predetermined angular distance from a desired angular position thereof. Control means also cause the rotation of the rotary table to stop in response to the number of signals from the generating means, when the rotary table is rotated to the desired angular position thereof.

  • Patent number: 4166402
    Abstract: An indexing rotary actuator for applying the torque of a rotatable pivot arm to rotate a member between plural index positions. The forward stroke of the pivot arm drives a slider crank linkage through a four bar linkage to unlock the rotatable member and rotate the member to its next index position. On the return stroke of the pivot arm a spring biased locking arm on the rotatable member is interlocked with the actuator to lock the rotatable member in the index position. Interlock switches are provided to indicate when a rotated member is in a valid index position.

  • Patent number: 4050355
    Abstract: 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 movement. The indexing movement of the table is smooth and does not involve movement of the table at excessive speeds.

  • Patent number: 4008900
    Abstract: An indexing chuck assembly to hold a work piece so work may be performed on it in differently rotated positions, as on a lathe. The chuck block is rotated between a lifting arm and a table member, the bottom of the chuck block having a cammed shaft which moves both rotationally and linearly as the chuck block is raised and lowered by the lifting arm. The cam shaft has a plurality of yoke cam grooves which engage a biased cam follower in the table member whereby the cam follower follows a reversing cam path defined by the plurality of yokes, each yoke forming a pair of angular grooves in the configuration of a Y, a portion of each yoke being common to its adjoining yoke so that adjoining Y configurations are alternately reversed. Each yoke is defined by an upper pair of aligned rest stops and an intermediate lowered reverse stop, the cam follower imparting rotation to the chuck block as it moves in transit from one rest stop to the adjoining rest stop.
