Patent number: 9184548Abstract: A hand operated crimping tool comprising a body arranged between a distal end and a proximal end of the crimping tool, a tool head arranged distally on the crimping tool, and handles arranged proximally on the crimping tool, where at least one handle is pivotally arranged, and where the relative movement of the tool handles is connected to the relative movement of crimping dies, between which crimping dies at least one workpiece is arranged to be crimped. The tool head comprises a main head part and a pivotable head part, where the movement of the pivotally arranged handle(s) is connected to the movement of the pivotable head part via the body and a mechanism, whereby the pivotable head part of the tool head is movable between an open head position and a closed head position depending on the relative position of the tool handles.Type: GrantFiled: April 13, 2012Date of Patent: November 10, 2015Assignee: Pressmaster ABInventors: John Hutchfield, Lars Olov Persson, Niklas Jonasson

Patent number: 9083133Abstract: A hand operated crimping tool comprising a body arranged between a distal end and a proximal end of the crimping tool, a tool head arranged distally on the crimping tool, and handles arranged proximally on the crimping tool, where at least one handle is arranged pivotally to the body, and where the tool head is arranged axially slidable along the body. A distal crimping die is arranged at the tool head and a proximal crimping die is arranged at the body between which crimping dies a workpiece is to be crimped. The movement of the handles is connected to the movement of the tool head by a mechanism, whereby the tool head is movable between a distal non-crimping position and a proximal crimping position depending on the relative position of the tool handles.Type: GrantFiled: April 13, 2012Date of Patent: July 14, 2015Assignee: Pressmaster ABInventors: John Hutchfield, Lars Olov Persson, Niklas Jonasson

Patent number: 8418519Abstract: The invention relates to a hand tool comprising handles and jaws, where the jaws are operated by the handles, and where an anti-slip device is arranged on the outer side of the distal end of a tool handle. The tool handle has a hard surface with low friction enabling the users fingers to slide on the surface of the handle when squeezing the handles together, and the anti-slip device is arranged to be supported against a support surface in order for the user to be able to press the tool handles together in a controlled manner using a force (F) in excess of hand force.Type: GrantFiled: September 29, 2009Date of Patent: April 16, 2013Assignee: Pressmaster ABInventor: Lars-Olov Persson

Patent number: 4958433Abstract: A tool for stripping insulation from electric cables has two jaws. The jaws are mounted at one end on a pin and can be swung towards each other and latched in their swung-together position. The jaws are provided with a cable support means and a countersupport means or bed, for receiving a cable to be stripped. In their swung-together position, the jaws can be moved apart at one end thereof to a limited extent against the bias of a spring means which endeavors to hold the jaws together.Type: GrantFiled: November 16, 1989Date of Patent: September 25, 1990Assignee: Pressmaster Tool ABInventor: Lars-Olov Persson

Patent number: 4503574Abstract: A tool for stripping surface layers from elongate objects includes an elongate frame, a jaw means which extends along the frame and which is pivotally mounted in the frame and a leg which also extends along the frame and which is pivotally mounted in the frame. When the leg is pivoted towards the frame, the leg is arranged to swing the jaw means towards the frame, via a camming arrangement, against the action of a restoring means. At one end of the tool, the frame and the jaw means have mutually facing clamping surfaces, and a stripping knife means which is arranged between the frame and the jaw means for movement therealong from a starting position adjacent the clamping surfaces. The stripping knife means includes two carriers for a respective one of two stripping knives which are arranged to be brought together by means of the jaw means and which extend transversely relative to the frame.Type: GrantFiled: July 15, 1983Date of Patent: March 12, 1985Assignee: Pressmaster Tool ABInventors: Mats Norin, Lars-Olov Persson
