Patent number: 5953820Abstract: The hand tool has a shaft with a distal end which is configured to receive any one of a variety of different sized chisel or scraper blades or the like, via corresponding male and female dovetail connections, for example. Storage space for the extra blades, if desired, may be provided in the handle which is secured to the shaft, or may be provided via depressions in a panel of a tool case of the type commonly referred to as "gift cases". Where storage space is provided in the handle, preferably this is accomplished by virtue of a spring-loaded collar which overlies lower portions of elongated rotatable cover pieces, preventing rotation. When the spring-loaded collar is retracted, the cover pieces can be rotated, to reveal storage areas on either side of the handle.Type: GrantFiled: August 8, 1997Date of Patent: September 21, 1999Assignee: Maxtech, Inc.Inventor: Kailash C.

Patent number: 5303474Abstract: An improved safety utility knife has a hollow handle and a blade which is normally retracted within the handle, but can be extended by squeezing an operating lever. The lever is connected to the blade holder by a toggle linkage having a rearmost pin secured in a discrete support whose position is adjustable. A thumbscrew threaded into the support enables one to adjust the position of the support from outside the handle, and thus change how far the blade protrudes from the handle when the operating lever is fully depressed.Type: GrantFiled: November 30, 1992Date of Patent: April 19, 1994Assignee: PSI, Inc.Inventors: Ronald Keklak, Michael V. Couture, John C. Whitehouse

Patent number: 5301428Abstract: A releasably locking handle for a retractable blade utility knife The handle is formed from a pair of elongated mating handle halves connected by a central pivot. A slidable blade carrier is supported between the handle halves. The handle has a dual locking mechanism which provides for pivotal opening of the handle only when the blade carrier is in a fully forward position. A magnet which is fixed in the handle slidably supports the blade carrier.Type: GrantFiled: March 10, 1992Date of Patent: April 12, 1994Assignee: The Stanley WorksInventor: John H. Wilcox

Patent number: 5283954Abstract: The blade includes a frame body designed as latticework which forms together with two handle shells which can be snapped onto its side the blade handle, and includes a blade which can be clamped by a clamping screw which can be screwed into the frame body into a thread thereof located at the foreward end section of the knife handle, which blade is pressed against a supporting body covered by hard metal and located in the frame body. By the pressing of the blade against the hard metal by means of a clamping screw of which the diameter is larger than the width of the blade any kind of blades can be clamped in the knife handle without using the form locked arresting between blade and knife handle for instance in form of recesses at the edge of the blade such as common at the blades of various designs being generally available on the market. The knife can, therefore, be used with all blades available on the market.Type: GrantFiled: November 17, 1992Date of Patent: February 8, 1994Inventor: Stephan Szabo

Patent number: 5282316Abstract: The invention provides a hand held razor-containing cutting device formed from two separable halves that are connected together during use along a centrally located longitudinally extending parting line. The two halves of the tool are held in contact with one another by means of frictional connecting elements that allow the halves of the tool to snap together for use. A pair of adjacent disassembly tabs are provided. One such tab is located on each half of the tool to facilitate separating the halves of the tool by prying the halves apart, usually with a screwdriver or similar tool that is placed between the tabs and then twisted to pry the tabs away from one another for separating the two portions of the cutting device so that the razor blade can be removed and replaced when required. The frictional connecting elements comprise C-shaped cooperating retaining studs that extend from one half of the tool and during assembly snap into openings provided in the other half.Type: GrantFiled: January 4, 1993Date of Patent: February 1, 1994Assignee: National Polymers Inc.Inventor: Dennis C. Anderson

Patent number: 5206965Abstract: Cutting structure for scoring or cutting surfaces is disclosed. The cutting structure includes a housing having elongated sides, a blade and thumb positioning structure associated with the elongated sides. Measurement means may be positioned against the thumb positioning structure and may be held in place by the user's thumb thus providing a measured distance which may be cut. The invention further includes angled structure associated with the housing which provides a guiding surface when making angled or mitered cuts along the edge of drywall. The invention may also include a retractable measuring structure retained within the housing, a retractable blade, retaining means formed in the housing for housing spare blades and a notch for cutting rope and the like.Type: GrantFiled: November 22, 1991Date of Patent: May 4, 1993Inventor: Mark Rowley

Patent number: 5168628Abstract: A shaving apparatus for flat and contour shaving makes it possible to distribute in the form of a think film on the skin just prior to shaving a cosmetic or pharmaceutical preparation. It comprises an applicator part, a feed part and a blade part, the blade part and the applicator part together forming the razor head (1), while the feed part forms the razor handle (4). The preparation is applied by means of a roll (5) or a spatula-like part, on which rotates a thin film of the preparation supply shielded from the outside. The feed device comprises a preparartion reservoir (6) and a miniature pump (5), which is arranged in such a way that it can easily be operated during application by the fingers guiding the razor and consequently during shaving preparation is fed into the applicator. The blade part comprises at least one blade functionally cooperating with the applicator part.Type: GrantFiled: June 19, 1991Date of Patent: December 8, 1992Assignee: Kai Industries Co., Ltd.Inventors: Elmar Mock, Daniel Schirmer

Patent number: 5168630Abstract: A blade-carrier tool of the type forming a handle for holding in the hand, and provided at its front end with a removable blade which is held in position by a clamping mechanism including two jaws between which the blade may be engaged. The jaws of the clamping mechanism are connected to respective levers serving to control the clamping mechanism. The levers are suitable for occupying an open first position in which the jaws are moved apart from each other, and a closed second position which is spontaneously locked under the action of declutchable locking means, in which position the jaws bear against respective opposite sides of the blade and hold it securely in position.Type: GrantFiled: December 27, 1991Date of Patent: December 8, 1992Assignee: Societe Anonyme dite: Rougier-mur-Sol ayant son siege socialInventor: Bernard H.
