Abstract: The spool for storing and distributing linear product has a drum and inner flanges defining the ends of the drum. The drum is configured to receive a linear product wound about the drum. The inner flanges have locking gears on the outside faces of the inner flanges. The spool has an axle supporting the inner flanges and a pair of outer flanges. The outer flanges each have an outer flange gear positioned in their inner face and corresponding to the inner flange gear. The inner and outer flange gears cooperate to allow the drum to rotate in a first direction but not a second direction when the spool is supported by the outer flanges. The outer flanges are slightly taller than the inner flanges such that the spool may be positioned on a flat surface (e.g., truck bed or ground) and unwound without any equipment.

Abstract: A mechanical device for the fast exchange of jaws in a lathe plate providing an intermediate jaw support attached to the jaw holder with a straight support face and providing with a guide wherein the jaw is positioned and fixed precisely and eliminating the clearances found in the conventional method.

Abstract: A pottery holding device and method for securely holding a workpiece during rotation and working of the workpiece on a wheelhead of a pottery wheel. The pottery holding device includes a wheelhead member and at least three holding members. The wheelhead member configured for attachment to the wheelhead of a pottery wheel. The at least three holding members and wheelhead member configured to allow selective locking of the at least three holding members in positions about the periphery of a workpiece. The device adapted to securely hold circular, non-circular symmetric and irregular, asymmetric or organic shaped workpieces. The device further adapted to securely hold workpieces in positions and orientations such that the center of the workpieces is aligned with the axis of rotation of the device, and positions and orientations such that the center of the workpieces is spaced from the axis of rotation of the device.

Abstract: The device is constructed with a tensioning spindle (12), a counter-holder (14) and a carrier (30), at least the tensioning spindle (12) being mounted such that it is rotatable about the longitudinal axis, and the carrier (14) being fixed to the tensioning spindle (12) and, when the workpiece (50) is clamped between the tensioning spindle (12) and the counter-holder (14), being capable of being brought into engagement with the workpiece (50) in such a way that it transmits a rotary movement of the tensioning spindle (12) to the workpiece (50). The device furthermore provides for the carrier to have a spring element (30) which can be coupled to the workpiece (50) under prestress to transmit a torque.

Abstract: A collet chuck assembly for an axially fixed collet head. The collet head is fixedly and removably mounted in a threaded bushing to prevent axial motion, and is keyed into place to prevent rotation. A sleeve assembly has cam surfaces adapted to engage the cam surfaces of the collet head to open and close the collet head, and slides between collet head open and collet head closed positions within a spindle adapter body. The sleeve assembly has projections that extend from a rearward portion and pass through appropriately sized passages in the axially-fixed bushing. Motion from a spindle drawbar is transmitted by a drawbar link-up through the projections of the sleeve assembly. Using this arrangement, no physical connection is required between the drawbar link-up and the sleeve assembly. Additionally, no cap assembly is required.

Abstract: A face-driver assembly and method for accurate coupling of a face driver with the spindle of a rotary-drive machining device. The assembly includes a face driver, a hub on the spindle defining a prealignment bore, a pair of self-centering coacting tooth sets on the hub and face driver, an engagement post extending into the hub and forming a prealignment shaft closely complementary to the prealignment bore, and a releasable coupling to hold and draw the engagement post rearwardly and thereby join the tooth sets in a manner facilitating final accurate centering.

Abstract: To allow a lathe to turn the photoreceptor drums, charge rollers and developer brushes of printers, copiers, and facsimile machines, a unitary component adapts the object so it can be held on the lathe and drives the object. The adapting portion includes a flexible material such as a hose or o-ring to snugly receive the end extension of the drum, roller or brush. The drive portion connects with the drive bolt of the lathe and spins the object. In a second embodiment, the drive and adapter portions are separate components. A bore in the drive bushing is lined with a short piece of hose or one or more o-rings and snugly receives a protrusion from the adapter unit. A third embodiment replaces the drive bushing with tail stock forced against the adapter unit by the drive bolt of the lathe. A bore in the adapter unit lined with a flexible hose or o-ring snugly receives the end of the tail stock.

Abstract: A method and apparatus are provided for holding and positioning objects for a single diamond point turning operation. The objects which may include liquid phase epitaxy films are mounted on multiple platforms (10, 46). The platforms (10, 46) are securely connected to a base (20). The platforms (10, 46) are positioned, independently from one another, for elevation and orientation relative to the base (20) while the platforms (10, 46) are securely connected to the base (20).

Abstract: Components are disclosed which allow a powerful, variable speed lathe to turn the photoreceptor drums, charge rollers and developer brushes of printers, copiers, and facsimile machines. In one embodiment, adapter units fit over the cylindrical extensions on the ends of the drum. Two pieces of opposing tail stock support and hold the drum on the lathe by applying pressure against the adapter units. A drive bushing is attached to and rotates with the drive bolt of the lathe. The drive bushing has one or more drive pins which interact with the spoke-like members on the drum to turn or spin the drum and allow it to be cleaned, polished, coated or otherwise treated. In a second embodiment, a short length of hose is used to connect the adapter unit with the charge roller or developer brush. The drive pin of the drive bushing is received in a hole on the surface of the adapter unit facing the drive bushing. The roller or brush is turned on the lathe by having the drive bushing turn the adapter unit.

Abstract: A machine tool has a pair of rotary spindles which support opposite ends of workpiece to be machined. At least one of the spindles is driven and a ring having a plurality of arms is coaxially secured to this spindle for rotation therewith. The arms entrain an annular member which is essentially coaxial with the spindles and is provided with threads. An annular guide plate which is again essentially coaxial with the spindles supports a plurality of clamping jaws for movement radially of the spindles. The clamping jaws are provided with threads which mesh with the threads of the annular member so that rotation of the latter can cause movement of the clamping jaws. A plurality of rocker arms is mounted on the machine tool for pivotal movement between an inoperative position and an operative position in which the rocker arms engage the periphery of the guide plate to prevent rotation thereof.
