Patent number: 4162641Abstract: An assembly for automatically feeding workpieces to and from a numerically controlled turret punch. A loader magazine having an adjustable volume for receiving a stack of workpieces is disposed on one side of a turret punch, and an unloader magazine having a similar adjustable volume for receiving a stack of workpieces is disposed on the opposite side of the turret punch. An ejector associated with a loader magazine ejects the top workpiece from the loader magazine to horizontally feed it into operative association with clamps of the turret punch. The turret punch clamps are moveable with respect to the punching tools, and the punching tools are moveable and operated to effect punching of the workpiece until it has a desired finished configuration.Type: GrantFiled: October 28, 1977Date of Patent: July 31, 1979Assignee: Potomac Applied Mechanics, Inc.Inventor: James H.

Patent number: 4159793Abstract: A tool for preparing the ends of optical fiber waveguides prior to such operations as coupling and splicing. The tool is adapted for single-handed operation and comprises a pair of manually actuated handles, first and second fiber supporting surfaces, and a third fiber supporting surface between the first and second surfaces. The optical fiber waveguide is secured to the first and second surfaces by a pair of clamping members which are responsive to the squeezing of the handles. Once the fiber waveguide is secured to the surfaces, further squeezing of the handles produces separating rotation of a pair of jaw members to put the fiber under tensile stress. A cutting blade suspended above the third surface is released to produce a peripheral microcrack on a portion of the optical fiber waveguide lying on the third fiber supporting surface.Type: GrantFiled: February 16, 1978Date of Patent: July 3, 1979Assignee: GTE Laboratories IncorporatedInventors: Carl Belmonte, Mark L. Dakss, John E. Fulenwider

Patent number: 4158977Abstract: A mat cutter employing a razor blade and providing protection against the blade's bending towards either of its sides. The cutter, used for preparing mats for photographs and other art objects, has a base upon which it sits and a section which slopes upward. A holder for a razor blade pivotally attaches to the sloping section and can rotate the blade into and out of a cutting position. When in its cutting position, the blade fits inside of a slot in the base and extends beyond only enough to effect the 45.degree. desired cut. The two sides of the slot prevent the blade from flexing towards either of its flat sides. With the blade thus surrounded and hidden from view, the cutter also employs a marking device that allows the proper placement of the cutter from a mat's edge to cut along a desired line. The cutter also includes starting and stopping marks so that it may produce a cut of the desired length using similar lines along the other sides of the mat.Type: GrantFiled: December 8, 1977Date of Patent: June 26, 1979Inventor: Malcolm Logan

Patent number: 4156377Abstract: A single fluid power operated piston connected to a tool operating arm pivoted intermediate its opposite ends, undergoes movement through a predetermined stroke between limit positions to alternately perform punching and shearing operations at spaced stations along a common support bed of a metal working machine. The tool operating arm is held in one of its limit positions by the piston device under control of a selector valve while a foot pedal operated valve is displaced against a spring bias by the operator to effect powered displacement of the piston device to the other limit position in order to effect either a punching or shearing operation depending on the position of the selector valve. A shearing operation may also be performed through a second shear arm pivotally connected to the frame and actuated by the piston device.Type: GrantFiled: September 16, 1977Date of Patent: May 29, 1979Inventor: Floyd V. Bracewell

Patent number: 4156378Abstract: A simple direct acting mechanism moves a circular rotatable disc cutter or two such cutters first to rollably engage a hard surface and then to traverse the surface to part the stock between a side-by-side pair of cords or wires. The cutter or cutters are blunt edged, as well as unheated and so avoid baring the cords or wires while parting the stock without the undesired effect of sharp or hot knives. The cutter or cutters are shiftable along the axis or axes to accommodate deviation of the cords with respect to the travel of the cutter. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.Type: GrantFiled: November 25, 1977Date of Patent: May 29, 1979Assignee: The Goodyear Tire & Rubber CompanyInventor: Gilbert A.

Patent number: 4155282Abstract: A cutting mechanism includes a removably mounted backing roller having a longitudinal axis of rotation and a rotatably mounted cutting member having a cutting edge and a longitudinal axis of rotation disposed parallel to the axis of rotation for the roller member. The roller member rotates in a fixed relationship with respect to the cutting member so that the cutting edge operates at substantially the same surface location of the circumferential surface of the backing roller to cut film thereagainst upon each revolution of the cutting member. The roller member is mounted to resiliently float in a direction transverse to a plane extending through the axis of rotation for the cutting member. The drive of the rotating elements is effected through the use of a timing belt operating from the main drive of the machine on which the cutting mechanism is mounted.Type: GrantFiled: February 28, 1978Date of Patent: May 22, 1979Assignee: Scandia Packaging Machinery Co.Inventor: Andrew W.

Patent number: 4151770Abstract: Two webs of different widths of microfoam are fed from web rolls by a continuously driven roller and a pinch roller through a heated-wire cutting station. At the cutting station, a single cutting wire extends across the path of both webs; a single set of clamping plates is also provided. The feed of the webs may be alternately interrupted by a clamping device which includes a pivotal clamp support that can be swung in a rocking motion back and forth about its pivot axis. A pair of U-shaped channels located on either side of the support pivot axis extend across the width of both webs and can be swung respectively toward and away from the webs. Removable clamping segments are fitted into a portion of each U-shaped channel to define adjustable length clamping elements which extend across the widths of respective webs for accommodating various sizes of webs. By swinging the clamp support between two positions, the clamping device alternately clamps one or the other web against a fixed clamp bar.Type: GrantFiled: October 14, 1977Date of Patent: May 1, 1979Assignee: Flexible Design Packaging Machine CompanyInventors: Joseph J. D'Angelo, Lawrence S. Maccherone

Patent number: 4150593Abstract: An apparatus for selective attachment to a rotary microtome in order to permit separation of the specimen from a cutting knife during the return stroke of the specimen. A small frame is adapted to fit within the conventional specimen holder or chuck of the microtome; and the frame carries a solenoid with a movable core. Attached to the forward end of the movable core is an auxiliary specimen holder; attached to the other end of the core is a plate against which a compression spring constantly presses. The preferred power supply for the solenoid is a filtered 30 volt DC power supply. The solenoid is energized only during the downward, cutting stroke of the microtome, and it is de-energized before the arm starts its return stroke. The spring urges the specimen holder away from the knife when the solenoid is de-energized. The apparatus may be readily installed on any conventional rotary microtome with minimal skilled labor; and it may be removed at will to restore the microtome to its original condition.Type: GrantFiled: April 21, 1978Date of Patent: April 24, 1979Inventor: James K.
