Abstract: This relates to a utensil such as a spoon which is collapsible to occupy a minimum of space. The utensil preferably has a handle formed in two parts joined together by a hinge with there being a releasable interlock between the two handle parts adjacent the hinge for maintaining the handle parts in longitudinal alignment and as an extension of one another. The handle parts may also be provided with cooperating interlocking structure for maintaining the handle parts in longitudinally aligned overlapping relation when the utensil is collapsed. This abstract is not to be constructed as limiting the claims of the application.

Abstract: A slitter is disclosed for slitting a cable-like item longitudinally to a controlled depth with a blade. The cable-like item is drawn through a guide which is shaped to correspond to the cross-section of the item, thereby ensuring proper twist as the item is drawn under the slitter blade.

Abstract: A nut mill for cracking the shells of nuts to permit easy removal of the nut meats from the nuts, including a frame mounting a rotatable, substantially cylindrical, multi-sided breaker, and a cracking plate positioned in relation to the breaker to receive a nut therebetween, which, when the breaker is rotated, the nut is compressed and cracked. The cracking apparatus is mounted in a housing which includes a hopper for feeding whole nuts through the cracking apparatus, and a drawer bin for receiving the cracked nuts.

Abstract: A hand carried, hand operated portable apparatus for destroying hypodermic needles is disclosed herein comprising a housing having a lever arm pivotably mounted on the housing engaging a shearing blade which travels through an internal channel through the top of the housing. A removable container having a longitudinal groove formed by inwardly disposed wall members is press fitted into the housing. A needle from a hypodermic syringe is placed in the longitudinal groove and pressed into the interior of the container in such a manner that the needle remains inside the container after it is cut from the hypodermic syringe.

Abstract: An electric jigsaw includes a motor housing, a shoe having a pivot arch and a shoe plate, the arch securing the shoe plate to the jigsaw housing for relative pivotal movement of the housing and shoe plate about the longitudinal axis of the arch. The improvement comprises an axial cavity defined by the arch and the shoe plate, and a plug removably disposed in one end of the cavity, the plug including a plurality of axially-extending slots open at one end thereof for removably receiving attachments for the saw.

Abstract: A tool for applying compression, e.g., a nutcracker, having a hinged pair of lever arms pin connected to a common housing. The housing contains a stopping device designed to provide a fixed crushing rotation movement to crush the nutshell without crushing the nutmeat. Furthermore, when a nut or other workpiece is not inserted in the tool, the lever arms are free to move, without restraint, making insertion of the nut a convenient and random action. From the standpoint of the user, the nutcracker will look like and operate exactly like the majority of nutcrackers in use today. The major difference is the stopping action, which will prevent damage to the nutmeat and allow less fragmented crushing of the nut shell.

Abstract: An open razor comprises a blade holder 2 pivoted to a protective cover 3 into and out of which it can be folded. The blade holder 2 supports a blade unit 8 formed by a blade 9 sandwiched between two side members 8',8" of plastics material. Guide grooves 15',15" in the side members are engaged by the inwardly-directed flanges 16',16" of a clamping rail 7 forming part of the blade holder.The blade units are stored in a dispenser from which they can be withdrawn by sliding the rail 7 fully on to a blade unit and then lifting one end of the rail to lift the blade unit against the force of resilient retaining projections which engage opposite ends of each blade unit to hold it in the dispenser.

Abstract: Replaceable blade type medical scissors are composed of scissor bodies and replaceable blades. Each of the replaceable blades is composed of a blade portion made of a metal plate which is bent such as to have an arcuate cross section and a retaining portion which is constructed by the metal plate bent into an envelope form which gradually increases in width towards the base portion. Each replaceable blade is adapted to allow plastic deformation and is integrally provided at the base portion of the blade portion. An insertion piece which is provided at the end portion of the scissor body is inserted into the retaining portion of the replaceable blade while the retaining portion is slightly expanded. The replaceable blade is removably secured to the scissor body by the elastic contracting force of the retaining portion.

Abstract: A cutting and scraping device is formed of two substantially identical sections which are joined together to form a slot which receives a razor blade having a blade edge and a handle edge. A locking member is provided to lock the blade in place with either its blade edge or handle edge exposed.

Abstract: A hair trimmer comprises a first cutter reciprocatory relative to a second cutter, the two cutters having parallel cutting edges provided with teeth; a resilient element urging the two cutters towards one another; and a coupling member coupled to the first cutter. The resilient element includes a central portion acting on the second cutter and adjoined by two resilient limbs extending from the central portion through an opening in the first cutter and then away from one another in opposite directions corresponding to the directions of the reciprocatory movement of the first cutter, the distal ends of the resilient limbs exerting pressure on the first cutter and bearing against the coupling member.

Abstract: A portable pipe cutter is provided having a rotating annular cutter with radially advancing blades which are driven as they are rotating around a stationary helically threaded plate. Small keys attached to each of the blades each have a threaded face which engages the helically threaded advance plate so that as the cutter member rotates, the inwardly directed blades not only rotate around a pipe but also advance linearly as a function of angular distance traverse. The unit is characterized by being portable, and having the rotating cutter member separable into semi-annuli, as is the bearing ring in which the cutter member rotates, so that the entire structure can be used anywhere along a continuous pipe, without being inserted over the end.

Abstract: A generally U-shaped bracket is provided having a pair of generally parallel legs interconnected at one pair of corresponding ends by a bight portion extending between and secured relative to the one pair of ends of the legs. An elongated handle is provided and mounted at one end from the longitudinal mid-portion of the aforementioned bight portion and the other end of the handle projects outwardly from the side of the bight portion opposite the side thereof from which the legs project. A one-piece elongated roller extends between and is journalled from the outer ends of the legs and the roller includes a cylindrical outer surface having at least two circumferential grooves formed therein spaced apart longitudinally of the roller and from the opposite ends of the outer cylindrical surface of the roller. The grooves include inwardly convergent opposite side surfaces defining an included angle of approximately 30.degree. and cylindrical bottom surfaces.
