Patent number: 6513245Abstract: A pinching tube cutting device to transversely cut a tube made of a plastic material. The device consists of two handles attached to each other in a pivoting movement around an axis wherein one handle contains a cutting blade at its end while the end of the other handle contains a hollow seat to receive the tube. The blade has two sharp edges making a salient angle between 120° and 150°, in such a manner that an angle (&agr;) formed by the sharp edge furthest from the axis and a line passing through the point of the blade and the axis is larger than the angle (&bgr;) formed by the other sharp edge and the line. The point of the blade describes a circular arc which cuts the segment of a line which joins the axis and the center of the tube with the largest diameter possible to rest in the seat.Type: GrantFiled: September 5, 1997Date of Patent: February 4, 2003Assignee: Virax, S.A.Inventor: Claude Aubriot

Patent number: 5074046Abstract: A manual sheet metal cutter (10) with a movable upper blade (12B) laterally offset from and integrally formed with a lower movable handle (12A) pivotally connected to, and sandwiched between, a stationary blade member (14) on the offset side of the movable blade (12B) and a stationary handle (16), of which are all pivotally connected together by a single fastener (11) defining a pivot axle. A rearward extension (14A) of the stationary blade (14B) defines an alignment section which bears against a mating alignment portion of an intermediate section (12C) of the movable blade member (12) to maintain the blades (12B, 14B) in correct cutting relationship. The fastener (11) enables pivotal adjustment of the angle of the stationary handle member (16) relative to the stationary blade member (14B), and an arcuate lower edge (14C) of the stationary blade member (14) defines a rocker to facilitate rocking, cutting movement.Type: GrantFiled: August 2, 1990Date of Patent: December 24, 1991Inventor: Eugene Kolesky

Patent number: 4967475Abstract: An improved all-way offset snips with full width wire cutter has bosses through which first and second blade members are pivotably connected for rotation about an axis perpendicular to the pivot bosses. The blade members have extended offset cutting surfaces with respect to the pivot bosses to permit the cutting of irregular shapes, particularly sharp curves and especially small circles, including opposing circles of about 2.0" to 2.5" diameters. The cutting surfaces are rotatable between an open position and a closed position for cutting the sheet material therebetween. The pivot bosses and the cutting surfaces are adapted for removal of material therefrom to permit resharpening of the offset snips while maintaining the offset of the cutting surfaces. The shanks of the blade members are also provided with wire cutting means, preferably a pinch cutter capable of being a limit stop for limiting rotation of the first and second blade members.Type: GrantFiled: September 30, 1988Date of Patent: November 6, 1990Assignee: Prosnip CorporationInventors: James R.

Patent number: 4462157Abstract: An improved heavy duty snips and shears useful for cutting sheet metal or other stiff or rigid material. The improved snips and shears include a lower blade having a substantially horizontally disposed body. The body of the lower blade comprises a first horizontal section, an intermediate downwardly inclined section, and a second horizontally disposed section. The inner edge of the intermediate section forms a cutting edge which is turned upwardly such that the cutting edge is raised above the first and second horizontal sections. The upper blade of the snips and shears is pivotally attached to the lower blade and includes a downwardly extending heel disposed at the rearward end of the cutting edge. A machine ground boss is formed on one of the blades and provides a friction surface which provides a pressure point of minimum area to facilitate sliding contact of the two blades.Type: GrantFiled: August 14, 1981Date of Patent: July 31, 1984Assignee: The Stanley WorksInventor: John M.
