Abstract: This invention pertains to an improvement in box joint tools and particularly for reducing play resulting from wear of the members forming the box joint. The box joint is formed in the usual manner. This improved joint is used when or where wear develops or may be utilized with new tools at the time of assembly. A first portion outer member of the box joint is machined to provide a counterbore and an enlarged bore in this member portion. A counterbore is also formed in the second outer member portion and extends to about one thirty second of an inch from a central jaw tongue portion. This counterbore provides a flexure portion with a smaller bore axially coincidental with the axis of the central portion. A pivot pin bushing has a threaded bore and is sized to be a press fit in the formed counterbore and enlarged bore of the first outer member. This bushing is mounted in the first outer member and the shank portion extends into the tongue portion of the central jaw.

Abstract: A belt buckle knife is disclosed in which a knife portion can be removed with the knife blade locked in its open position without the need of removing the belt buckle knife from the belt. The belt buckle knife includes a buckle portion which engages and fastens the belt independent of the knife portion being attached to or removed from the buckle portion. The knife portion is selectively operable from a knife closed position to a knife open position. In the knife closed position, the knife blade is engaged by a part of the buckle portion, with the knife portion and the buckle portion being securely fastened together. In the knife open position, the knife blade is locked open with respect to the knife handle, and the knife portion can readily be removed from the buckle portion.

Abstract: A combined pocket knife and money clip has a casing formed of two disc like pieces of injection molded plastic which have a cavity therebetween, a grommet which extends through the casing, a blade pivotally supported on the grommet within the cavity, a spring clip which is retained on the casing by the grommet and cooperates with the casing as a money clip, and a linear spring wire within the casing. The spring wire acts on a cam portion of the blade to bias the blade to an interior position in the cavity and to an exterior position where its cutting edge is located outside the casing.

Abstract: A curling iron includes a tubular barrel extending forwardly from a hollow handle. The barrel contains an electric heating element and is provided with a spring-biased pivotable hair holding clamp conforming to the surface of the barrel. The barrel and clamp are pivotal as a unit about 180 degrees from the extended operative position into a folded storage position within the handle through a side opening in the handle. The opening is closed by a pair of inwardly pivotable doors which are spring-biased to an outward closed position conforming to the outer surface of the handle. Pivotal movement of the barrel from its extended position causes contacts on the barrel to separate from spring contact elements fixed in the handle to disconnect the heating element from its electric power source. As the barrel and clamp are folded into the handle through the opening, the doors are pushed inwardly out of the way so that the handle may receive the barrel and clamp for storage.

Abstract: A scissors, preferably for use as one of the elements in a pocket knife such as a jackknife, which is biased to an open position by a concealed spring. The scissors includes two rectilinear blades which are pivotally secured to each other by a pivot at a point intermediate the ends of the blades. The blades are biased to open position in which the blades are at an acute angle to each other by the spring, which is mounted about the pivot. The spring includes a single flat coil which spans an arc of less than 360.degree., typically 270.degree.. One end of the coil has an integral leg perpendicular to the plane of the coil and parallel to and adjacent the pivot. The other end of the coil extends tangentially away from the arc of the spring coil. One of the blades has a pocket, including an extension, adjacent the pivot. The other blade also has a pocket adjacent the pivot, and the leg is located in this pocket. The spring is disposed in the pockets with the coil of the spring extending about the pivot.

Abstract: A folding blade pocketknife having a pivotally mounted leaf-type spring, one end of the spring being in contact with a cam surface of a pivotally mounted blade, the opposite end of the spring being in contact with a moveable surface, said moveable surface being adjustable for adjusting the effective tension of the knife blade.

Abstract: A horseman's pocket knife has a handle into which a plurality of useful blades can be folded. The knife includes a hoof-cutting blade with a cutting edge along one side. A hook-shaped cross section is established at the end of the hoof-cutting blade and its tip is also provided with a cutting edge. The width of the hoof-cutting blade toward the hooked end and the size of the hook are dimensioned so that the cutting blade can be folded into the handle without interferring with the handle or other blades. A hoof-cleaning blade in the shape of a hook in the plane of the blade may also be provided for removing stones and other debris from the horse's hoof.

Abstract: A pocket-sized claw-like multibladed weapon adapted to be held in the closed fist with the blades being spaced apart and projecting outwardly between adjoining fingers; likened to animal claws or talons of birds of prey. For storage and handling of the weapon, the blades are retractable, foldable, pivotable, and/or otherwise reposable in a confined manner, so that the weapon may be safely carried in the user's pocket or purse while occupying a minimal space. The weapon may be rapidly converted or erected from its reposed condition to its activated position when required.

Abstract: The foldable blade knife comprises a blade with a tang positioned between the arms of a flat U-shaped handle at the ends of the arms away from the base of the handle, and a pivot pin extends through the arms of the handle and through the tang equidistant from the butt of the tang and the ends of the arms. The handle defines an opening sized and shaped to approximately correspond to the size and shape of the blade element, and at least one edge surface of the tang and the facing surface of an arm of the handle are formed in interfitting convex-concave shapes so that the resilient arms of the handle tend to hold the blade folded into the handle or to hold the blade extending out coextensively from the handle and when the handle is grasped by a hand, the gripping force by the hand tends to further lock the blade in its open or closed positions.

Abstract: Inspection of can double seams is performed by cutter which approaches can in a relative direction and location to both sever the cover hook and move it along the can without damage to the body hook. The cutter is caused to move at a small angle away from the can during the cutting action to avoid damage to the body hook.
