Patent number: 5065516Abstract: disassemblable scissors which utilizes a releasable pivot joint between pivotable scissor halves. The pivot joint is formed in the scissor halves between the blades and the handles of the scissor. The scissors halves are pivotally retained together over a range of cutting motions by a retaining assembly. The retaining assembly retains a portion of one of the scissors halves movably within a retaining portion of the other of said scissors halves at least over the range of cutting motions. To release and disassemble the scissors, the scissors halves must be pivoted at least past the range of cutting motions to a point where the portion of the one scissor half is no longer retained by the retaining portion of the other scissors half. In this position, the two halves can be transversely pulled apart.Type: GrantFiled: November 6, 1989Date of Patent: November 19, 1991Assignee: Andrew Tool CompanyInventor: David H. Dulebohn

Patent number: 5046252Abstract: A cutter for optical fibers includes upper and lower frames pivotally connected at their ends pivotally movably relative to each other, a cutting blade provided on the upper frame for cutting optical fibers and supporting device provided on the lower frame for supporting an optical fiber to be cut. The upper frame includes a regulating device for moving the cutting blade in its longitudinal direction and stopping and fixing the cutting blade and a confirming device for visibly confirming a position where the cutting blade is fixed. With this arrangement, there is no need for exchanging of cutting blades every cutting of a fiber. Moreover, a cutting blade portion to be used can be visibly identified and it can be prevented to use again once used cutting edge portion of the cutting blade.Type: GrantFiled: April 23, 1990Date of Patent: September 10, 1991Assignee: Daiichi Denshi Kogyo Kabushiki KaishaInventors: Tokuichi Ayuta, Kazuhiro Ohtsuki

Patent number: 5038477Abstract: An apparatus for cutting aluminum siding or like articles includes a movable blade and a pair of fixed blades between which the movable blade is mounted to pivot. The fixed blades are each mounted on a rail that is rigidly connected to a flexible base member. An adjustment bolt is provided for exerting force between the rails. Force from the adjustment bolt causes the base member to deflect, thereby permitting the distance between the fixed blades to be varied. A second feature includes the provision of different sets of fixed blades, each configured to conform to a different type of siding. A novel movable blade is also provided.Type: GrantFiled: June 26, 1990Date of Patent: August 13, 1991Inventor: Harold A. Parrow

Patent number: RE39286Abstract: A cutting device especially designed for cutting up salad greens includes two blades, a rib and handles. The two blades are inter-secured to rotate together about a common axis, but are spaced apart from each other along the common axis. The rib is pivotably secured to the two blades so as to rotate about the common axis, and is curved in a direction of rotation so as to have a concave surface. The handles are integrated with the two blades and the rib to control the two blades and the rib to rotate simultaneously between open and closed positions. The concave surface of the rib is the lead surface when moving from the open position to the closed position, and the cutting edges of the two blades cross edges of the concave surface when moving from the open position to the closed position, so as to perform a cutting action.Type: GrantFiled: April 8, 2003Date of Patent: September 19, 2006Assignee: Wenco, L.L.C.Inventors: Michael I. Silver, Wendy L. Silver, Eric Chan, Rama Chorpash, Ira Spool
