Abstract: A multi-purpose scraping apparatus is disclosed which enables the interchangeability of scraping blades. The apparatus is made of a handle, a shank and a blade receiving assembly, the shank being interposed between the handle and the blade receiving assembly. The blade receiving assembly comprises a back plate, a spring plate, a spring tongue and means for securing the spring plate to the back plate. The spring tongue extends from the spring plate and provides means for moving the blade receiving assembly from a gripping position to a releasing position. The back plate and the spring plate are thus constructed and arranged to cooperatively engage a blade to be used with the apparatus and to bias the blade receiving assembly in the gripping position. Thus, the spring tongue is moveable to effect movement of the blade receiving assembly from the gripping position to the releasing position.

Abstract: This invention relates to a utility knife having a handle with two or more angular bends. The utility knife has replaceable blade, which may be retractable, clamped in the nose of the knife handle. The knife handle is hollow and separable to accommodate the storage of spare blades in the handle. Most utility knives either have handles which are substantially straight or which have a single angular bend. These knives are more limited in their application or produce difficulty in cutting materials in an obstructed area. A knife having a handle with two or more bends enables the user to cut materials in close quarters or in obstructed areas with greater ease. Different handles provide greater reach or leverage under different circumstances. An alternative knife includes a handle with two or more angular bends, one of which is adjustable. This allows the user to select a configuration that offers optimum reach and leverage.

The shaft portion has a bore for receiving a collet and the knife includes a central knob for cooperating with the collet to clamp a blade into the collet when the knob is rotated in a first direction and to move the collet axially out from the handle, thereby freeing the blade, when the knob is rotated in the other direction.

Abstract: A standard cutting tool of the type commonly used to cut paperboard as a border for framing pictures or other objects is held in a two-piece clamp on the end of a curved arm. A first circular member on the other end of the arm has a surface which mates with a similar surface on a second circular member on the end of an elongated rod. The two circular members are placed in a desired rotational orientation and releasably held therein by a screw or other retaining means. One of two interchangeable, surface engaging, guide members is releasably retained at a desired position along the length of the rod, permitting the cutting tool to make either a circular or a straight cut in the paperboard with a beveled edge. The rotational adjustment of the two circular members permits the longitudinal axis of the blade to be aligned with the direction of blade movement when making circular cuts, thereby eliminating blade drag due to misalignment.

Abstract: A blade holder for holding a disposable ice shaving blade on an ice resurfacing machine has an attachment member which is attached to an appropriate support member on the ice resurfacing machine. The attachment member has an elongated "V" shaped groove which extends across the transverse width of the attachment member.

The tool generally has a handle, an elongated member with a longitudinal bore partially extending therethrough, and a removable and replaceable blade. The cutting portion of the blade is substantially U-shaped in cross-section with the exposed edges tapered and sharpened. The shape of the blade and its sharpened edges facilitate the cutting and removal of a channel within the urethane sealant in order to allow placement of a strip of plastic moulding which retains the windshield in place.

Abstract: A handle for use in connection with tool tangs of a wide variety of sizes and shapes includes a handle body molded of a plastic material and formed with a main blind bore whose end wall is formed with a centering bore of smaller diameter. The main blind bore serves for receiving tapering tangs of largest cross section, or a tubular insert. The insert has a first axial bore opening at one end of the insert and a second axial blind bore opening at the other end of the insert. The end walls of the first and second blind bores are interconnected by a passsage of reduced diameter. The jacket of the insert is split by an axially directed slot so as to facilitate plugging of the insert into the main blind bore in the handle body. The inner surface of the main blind bore and the outer surface of the insert are knurled to prevent rotation of the insert. The tapering tangs of the tool are held in position in the handle at two axially spaced areas.

Abstract: A holder for a detachable blade has a handle part and a blade retaining part formed by a pair of body sections pivotally connected for movement between open and closed positions. A latch member supported within the hollow handle part, and which retains the body sections in closed position, is released by manually operating an associated push button disposed in an aperture in the handle part. Coengageable clamping surfaces on the blade retaining part cooperate in clamping engagement to retain a blade in the holder when the holder is closed. A thumb rest on the blade retaining part reduces risk of accidental contact with a blade secured in the holder.

Abstract: A holder for an interchangeable knife blade comprising a handle, a chuck adapted to be threaded into the handle. The chuck has a bifurcated forward end defining a lengthwise slot for receiving a flat cutting blade, the bifurcated end defining a cam surface tapering outwardly toward the forward end to a major dimension. A tubular elastomeric ferrule is mounted on the chuck for longitudinal sliding movement relative to the chuck. The ferrule extends between the handle and the cam surface when the chuck is partially threaded into the bore, so that additional threading of the chuck into the bore causes the ferrule to slide forwardly over the cam surface. In this way, the forward end of the ferrule is stretched, thereby transmitting a clamping pressure against a blade which is located in the slot.

Abstract: The object of the invention is to provide a shovel blade attachment having both a brush and a cutter secured to the shovel blade by a common attaching assembly. Modifications of the shovel blade, such as drilled holes, are not required.

Said attachment (1) includes a brush (3), a cutter (4), and an attaching assembly (5). The cutter (4) has slots (12) or (13) for adjusting the exposure of the cutter (4) in contact with the shovel blade (2) in order that the shovel blade (2) absorb impact forces.Compression pads (9) help secure the attachment (1) to the shovel blade (2) and provide clearance (19) between a clamping plate (8) and an upturned end (20) of the shovel blade (2).

Abstract: The invention is directed to a clamping system for knives with angular cross-sections, especially suited for agricultural cutting operations in which a portion of the length of the sidepiece extending the cutting edge of the knife protrudes over the knife holder when the knife is clamped, with the clamping element engaging the knife in the area of its angular bend. This system allows for a reduction of knife thicknesses while maintaining other desirable characteristics, and provides the knife with greater strength in the area stressed by bending as compared with the unclamped position of the knife.

Abstract: A surgical blade holder characterized by a handle with a hollow head portion at an obtuse angle with the longitudinal axis of the remainder of the handle.
