The wire is drawn off continuously from the reel and is fed intermittently into the apparatus wherein it is cut off to lengths and gripped in the apparatus with the ends of the cut-off lengths a fixed distance apart and exposed. When the wire is thus cut off and gripped, it is moved at right angles to the length thereof along the apparatus while work operations are performed on at least one end of the lead, the work operations consisting of stripping insulation from the end of the lead and applying a terminal thereto. When the leads have been completely processed, the apparatus straightens the leads out in the direction of the length thereof and delivers them to a receiving station, and wherein the leads are counted and removed from the receiving station in batches of a predetermined number.Type: GrantFiled: August 27, 1975Date of Patent: December 14, 1976Assignee: Lyall Electric, Inc.Inventor: Carl W.

Patent number: 3990351Abstract: A pneumatic impact device comprising a housing, a drive piston and a piston rod. At the forward end of the piston rod there is attached a tool intended for metal working like punching, cropping or forging. The housing contains a drive chamber, an air charge chamber, a reverse chamber and a retard chamber. The piston rod is provided with two forward-facing, annular shoulders one of which constitutes a reverse piston for working in the reverse chamber and the other a retard piston for working in the retard chamber. For being protected from impact strains, the drive piston is longitudinally displaceable relative to the piston rod. During the working strokes, the drive piston cooperates with a backwardly facing shoulder on the piston rod, but just before the latter reaches the point where the tool hits the billet to be worked, the drive piston is stopped in the drive chamber and is thereby separated from the piston rod shoulder.Type: GrantFiled: December 5, 1974Date of Patent: November 9, 1976Assignee: Atlas Copco AktiebolagInventor: Bertil Waldemar Sundin

Patent number: 3983772Abstract: The disclosure relates to a cutting machine and more particularly to a cutting machine for cutting off short lengths of elongated material such as circular in cross section wire-like or tubular elements and more particularly to material commonly known as liquid silver which is small diameter tubular silver elements used to make necklaces or the like. The machine comprises a means for feeding intermittently a plurality of elongated work pieces in parallel relationship to each other and for sequencially and intermittently operating a circular saw which moves laterally relative to the work pieces and cuts off short lengths thereof. The machine comprises means for automatically sequencing the feed means and the cut-off means in timed relation to each other and such that, as for example, as many as 30,000 to 70,000 pieces may be cut in 1 hour's time.Type: GrantFiled: September 26, 1975Date of Patent: October 5, 1976Inventor: Dale R. Oldham

Patent number: 3954033Abstract: A method and apparatus for cutting cylinders of gelatinous material such as polyacrylamide gels into discs of precise thickness comprises a cutting surface which is placed in contact with the entire circumference of the cylinder. Cutting force is then applied from all points on the circumference at once, resulting in cutting the gel cylinder towards the center from all points on the circumference. This is accomplished by the use of a multi-bladed diaphragm similar to an iris diaphragm used for camera aperture control. The edges of the blades of the diaphragm form a variable dimension cutting surface.Type: GrantFiled: June 27, 1974Date of Patent: May 4, 1976Assignee: The United States of America as represented by the Secretary of the Department of Health, Education and WelfareInventors: Harold W. Tipton, John I. Peterson

Patent number: RE30927Abstract: An apparatus for simultaneously forming a plurality of terminals from a plurality of lengths of wire and inserting the terminals simultaneously into preformed openings in a plastic part. The apparatus includes a mechanism for simultaneously moving a plurality of lengths of wire which are held in spaced relation to one another to a severing position. The wires may be arranged in both horizontal and vertical planes. At the severing position, a shear is provided for simultaneously severing end portions from the lengths of wires to form a plurality of short wire terminals. The shears and an anvil support the terminals and maintain them in spaced relation to one another after severing for insertion into the preformed openings in the plastic part. The apparatus further includes a tool which supports the plastic part. A slide moves the plastic part and the terminals into engagement with one another to thereby embed the terminals in the preformed openings of the plastic part.Type: GrantFiled: January 26, 1981Date of Patent: May 11, 1982Inventor: Maurice H. Brown
