Abstract: A manually operated hair cutting device having a movable spring wire extending through the device. The wire has a base end for engaging one's head to regulate the length at which the hair is cut. The other end of the wire is connected to an activator which is adapted to be moved to forward and rear positions. As the activator is moved forward, the wire is moved through the device such that its base end is moved away from the cutting teeth. When the base end of the wire engages the head, and the activator is moved forward, the device moves upward along the wire. A movable stop normally prevents the handles from being moved together to prevent hair cutting action. An adjustable engager on the activator engages the stop and moves it out of the way as the activator moved forward to allow the handles to be moved together for hair cutting purposes.

Abstract: A bolt cutter device having a generally cylindrical body member in the form of a sleeve, and a shear body slidably movable therein, the body member having tapped openings each receivable of a bolt to be cut.

Abstract: A notching tool for forming notches in ridge- or hip-capping for roofs, the notches being formed to match the profile of the roofing sheets.The tool has a base with a pair of spaced feet which engage the ribs on the roofing sheets to align the tool. A notching head on the base has a replaceable die and punch pair, one of which is fixed to support the capping while the other is manually or power-operated to provide a shearing-type cutting action between the die and punch to cut the notches. Adjustable guides on the notching head support the capping for angular alignment between the capping and the notching head and for adjustment of the depth of the notch. The notching head may be pivotally and/or rotatably mounted on the base and the die and punch may be reversible.

Abstract: A hair cutting angle indicator for use with scissors or the like as an aid to cutting the hair at a desired angle with respect to the vertical. It includes an angle gauge mounted on an attachment removably mounted on the scissors. In one embodiment, the indicator holds the scissors at an adjustable desired distance from the head whose hair is being cut. In another embodiment, angular indicia are provided about a bar mounted to the handle of the scissors so as to indicate the angle of the cutting direction about the pivot axis of the scissors.

Abstract: The blades of a pair of suture scissors are pivotably mounted within a tapered hood. The nose of the hood is smoothly curved and a slot is formed thereacross such that the plane of the slot is in parallel alignment with the shearing line of the blades of the scissors. The width of the slot is such as to accommodate suture threads but not great enough to receive a knot in the suture. The mouth of the slot is smoothly curved to provide convex surfaces to assist in guiding the suture threads into the slot.

Abstract: A hedge cutting arrangement has a cutting device, a drive motor for driving the cutting device, a coupling arranged between the cutting device and the drive motor, two handles for two-hand operation, and two switching devices including actuating members, wherein the coupling is connected with both actuating members so that even when only one of the actuating members moves to its switching off position, the cutting device disconnects from the drive motor.

Abstract: Cutting dies are mounted for parallel movement in a scissors-action handle assembly employing pivot pins mounted both forward and rearward of the pivot axis of the handles, and one of the engagement openings for a pivot pin in each die is longitudinally extended for necessary clearance. The cutting edges of the two dies are at one longitudinal end of the tool extending beyond the portion of the dies between the two pivot pins. Parallel action is guided by a pair of guide pins longitudinally spaced and to the maximum extend possible located in the plane of the die cutting edges. A compression spring is centrally located between the guide pins to bias the dies to open position. When the dies are of the kind adapted to trim venetian blind slat ends, one die aligns the blind slat by transverse ribs to the cutting edge.

Abstract: A wire cutter having a pair of partially overlapping blade-shaped jaws pivotally connected, each jaw having an operating handle, a pin in one jaw blade being received in a slot in the other jaw blade to limit the pivotal movement, a plurality of holes in said jaw blades, said holes being countersunk in the outer surface of one of said blades, said holes being in alignment when said handles are in the maximum open position for the insertion of a wire to be cut, said holes in non-alignment when said handles are squeezed, thereby permitting said blades to cut wire, and a spring between said handles to return said handles to the open position.

Abstract: The nibbler apparatus comprises a quickly changeable rotating cutter having a modified sinusoidal groove of a predetermined width and depth. The rotating cutter is mounted in a die with the modified sinusoidal groove largely enclosed within the die. The modified sinusoidal grooved cutter picks up the material to be cut, carrying it upward into the die opening and there the material is sheared. Flat material can be cut in any direction and the direction of the material being fed into the cutter can be changed at any time.

Abstract: A guard member is secured at one end adjacent the pivot point of a pair of scissor blades having opposed cutting edges. The guard member extends away from the cutting edge at an acute angle and downward to form a narrow slot at the outside edge of the cutting blade forming an open space between the guard member and a substantial portion of the cutting edge.

Abstract: Manually operated tool, primarily a hand tool, for cutting strip elements, more especially, blind strips of Venetian blinds. The tool has cooperating blades. Associated with one of the blades is a feed guide particularly configurated to be adapted to the shape of the strip to be cut for accurate delivery to the blades. Associated with the blades also is a measuring gauge for accurately measuring the amount to be cut off. The blades are especially configurated to be adapted to cut strip material having transverse curvature and further to make a curved cut providing a finished end to the strip being cut.

Abstract: Shears for cutting or trimming hair are presented equipped with a device for indicating, to the hair-trimming stylist, the general angle relative to the horizontal at which the cut is being made. The indicating device disclosed is a spirit level with the usual single small bubble inside the level and, preferably with a plurality of marks spaced longitudinally of the level so that the angle is at least roughly indicated to the hair stylist.

Abstract: In the present invention, a pair of conventional sheet metal shears may be safeguarded quickly against hand injuries for conventional uses as well as equipped and prepared for special conditions, and, easily restored for other or regular uses with respect to either one or both shear blades of standard shears regularly employed for cutting and trimming sheet metal. An improved safety snap-on guard can be used for all work, either by re-orienting the guard or inverting the shears with the guard in place.

Abstract: A hand tool for opening the tapered plastic dispensing tip on material dispensing cartridges which includes first and second lever members pivotally interconnected at one end and each having a handle with finger receiving openings at the other end to enable operation of the tool with one hand, one lever member having a blade portion intermediate its ends formed with a plurality of openings of relatively different size corresponding to the external cross-section of the tapered tip at different locations therealong, and the other of the lever members having a sharpened blade adapted to shear off a portion of the tapered dispensing tip when it is inserted through one of the openings. A probe is provided on the tool adapted for insertion through the dispensing tip to rupture the seal in the cartridge.

Abstract: A hand tool having a cutting blade to cut and form ends on decorative molding is provided with a movable guide for supporting the molding material at different positions with respect to the blade such that ends and insert pieces may be cut from the molding material to form decorative ends on strips of molding material applied to a receptor surface.
