  • Patent number: 7134950
    Abstract: A center clamp used with a machining tool having an annular edge has a C-shaped body having an inner end inside the edge and an outer end outside the edge and spaced from it along a clamp axis. A push rod extends along the axis through the outer body end. A rotary joint centered on the axis has an inner part on the inner body end and an outer part rotatable on the inner part about the axis. An axial actuator relatively axially shifts the body and the push rod and thereby clamps a workpiece between an end face of the rod and the outer part of the joint. An angular actuator pivots the push rod about the axis and thereby, when the workpiece is clamped between the rod and the joint, pivots the workpiece about the axis.

  • Patent number: 4538383
    Abstract: Each workpiece holder of a grinding machine is reciprocated relative to and turned about an axis parallel to that of a wheelhead spindle. Workpieces carried by the holder are brought from in front of and to the side of an abrasive wheel front working surface into contact with the working surface. To prevent the pieces ground by the abrasive wheel from being scratched, after the workpieces have been ground, the wheelhead spindle is translated from a region where the grinding is performed. Simultaneously the workpiece holder is turned from in front to the side of the abrasive wheel working surface. The grinding machine, for instance, comprises two workpiece holders that are diametrally opposed with respect to the abrasive wheel. The holders turn in opposite reciprocating directions. The workpiece holders carry two half-holders for optical fibers having ends to be connected together. The ends of the fibers are simultaneously and coplanarly ground by the machine.

  • Patent number: 4261555
    Abstract: Disclosed herein is an optical vise used to securely fasten glasses thereto for performing maintenance functions, suitably constructed so that the glasses retained therein will not be marred or otherwise damaged while being repaired. The structure disclosed herein includes a pedestal providing a support for horizontally extending trays that serve to carry tools and parts, a vertically adjustable support structure which carries at its vertical extremity remote from the base and vise proper. The vise is capable of rotation about a horizontal axis and defines a nesting area for securing foam or a similar soft resilient rubber material which serves to constrain the eye glasses disposed in a slit between two such pads. A back portion of the vise is provided with a similarly spongy material provided with slits along one face thereof so that the arcuate portion of the glasses which when in use hook around the ears of the wearer slide within these slits to provide further support.

  • Patent number: 4252305
    Abstract: Vise jaw covers, each of which comprises a flexible, elongated panel made of soft, resilient, compressible material such as latex rubber, and having a relatively wide end portion severed along a U-shaped line to define an opening with an adjacent flap and having an intermediate portion and a relatively narrow end portion which is brought up and over the face of the vise jaw after the latter is forced through the opening and then outwardly and downwardly along the back of the neck of the vise jaw, through the opening and tensioned, whereupon the opening-defining portions clamp the panel in snug-fitting enveloping relation to the vise jaw with the soft intermediate portion stretched across the work-engaging surface of the vise jaw.

  • Patent number: 4027866
    Abstract: A multi-face clamp for wood working which comprises a clamping unit including a plurality of corner pieces. Each of the corner pieces defines at least two pressure faces which are adapted to engage complementary faces of a work piece. Two threaded bolts extend from and are operatively connected with the corner pieces. One of the threaded bolts has threads formed in an opposite direction from those of the other of the threaded bolts. A turn-buckle is disposed between each pair of adjacent corner pieces and receives in its inner threads the respective free end portions of the threaded bolts, so that upon turning of the turn-buckle the pressure faces of the corner piece exert pressure upon the complementary faces of the work piece.
