  • Patent number: 4708033
    Abstract: A tool for removing headed stoppers from bottles such as champagne bottles, includes a base having a two fingered yoke and a side support, sized and shaped to engage the upper lip and the side of the neck of the bottle respectively, so that when a handle, pivotally attached to the base, is lowered toward the bottle, a pair of inwardly biased jaws slide down over the head of the stopper to engage its undersurface between the fingers of the yoke. Thereafter, the handle is lifted extracting the stopper while inwardly facing extensions positioned above the stopper on the jaws restrict upward motion of the stopper to prevent uncontrolled motion thereof.

  • Patent number: 4620458
    Abstract: Screwing-in apparatus for set screws which can be operated by a wrench, for the connection of hollow rod elements with junction members of a framework, in which the junction members have threaded bores to receive the set screws and the rod elements have end members with middle bores for the passage of the shanks of the set screws. The heads of the set screws can be applied on inside shoulders of the end members for positioning. Other tubular elements are provided which extend inwardly from an opening in the wall of the rod element and open axially parallel to the middle bore in the end member and against it, in order to guide the drive elements of the screwing-in apparatus. A tubular, curved element forms a guide member for the screwing-in apparatus, in the rod element, in which a drive member or members are rotatable and axially immovable. The end of the tubular element which is turned away from the wrench is configured as a plug holder for the set screw.

  • Patent number: 4619160
    Abstract: The piston-cylinder unit (30') of a power wrench presses against the arm (16), by means of a ball and socket joint (44, 45), for swivelling the ring (11), which is connected secure against rotation to the wrench head to be turned. The piston (35) and the arm (16) have complementary spherical surfaces (40, 41) which press against each other. The dimensions of the spherical surfaces can be selected in dependence on the maximum power to be transmitted. The result is a uniform power distribution and a force-free adaptation of the movements of piston (35) and arm (16), without jamming and tilting.

  • Patent number: 4617843
    Abstract: An electrically-operated driver is constructed such that when a screw begins to be driven, axial movements of a bit is transmitted to a switch mounted on a reduction gear, which engages with a shaft of an electric motor, to turn on or off the switch. In the driver, a distance between the switch and a clutch bearing a thrust from the bit is made short so as to eliminate scattering in strokes required for actuating the switch, which scattering would be produced by axial accumulative errors of parts constituting an actuating mechanism for the switch. Accordingly, movements of the bit are transmitted to the switch with certainty to stably start and stop the motor of the electrically-operated driver.

  • Patent number: 4616533
    Abstract: A stripping device for coaxial cables comprises a handle member and a guiding track member for a predetermined end length of a cable, rotarily mounted in the handle member. Knife means, mounted in a knife holder which is pivotally attached to the guiding track member, are provided to perform at least two spaced incisions in the cable. A locking means connects temporarily an inserted cable non-rotarily with the handle member. By pivoting the knife holder towards the guiding track member and at the same time rotating the guiding track member with the attached knife holder about the cable locked in the handle member, a first incision is made and extended along the whole periphery of the cable by the knife means which is closest to the end of the knife holder remotest from the handle member.

  • Patent number: 4615242
    Abstract: A bottle opener for bottles having twist-off caps including a container having an end wall with an opening therein adapted for insertion of a bottle-mounted cap therein. A cylindrical member is connected to and extends into the container from the opening. The cylindrical member is open at the end thereof opposite the opening in the end wall and has a passageway adapted for passage of bottle caps through the cylindrical member and into the container. Longitudinal ridges on the interior of the cylindrical member hold an inserted bottle-mounted cap so that turning of the container about a longitudinal axis thereof extending perpendicular to the end wall causes the removal of the cap from its bottle. Preferably the opener includes means such as resilient fingers for preventing detached caps in the cylindrical member from falling out through the opening in the end wall.

  • Patent number: 4611515
    Abstract: In combination with a miniature jewelers' screwdriver, or similar tool, a barrel made of a stiffly flexible material (preferably a specified plastic) incloses the shaft of the screwdriver. The barrel provides at its working or tip end a set of flexible elements combined with a head holding groove to provide a gripping head which securely holds miniature screws or similar fasteners registered with the screwdriver tip. At the barrel's other end a coil spring around the shaft of the screwdriver exerts pressure to extend the barrel's tip beyond the bit of the screwdriver so that it will act to engage and hold screw heads.

  • Patent number: 4611513
    Abstract: Stepped roller pins roll within stepped lobes formed around the interior wall of a hollow cylindrical casing. A hollow cylindrical retainer or simple ring retainer hook into a recessed groove around the middle of the roller and interact with ridges or grooves in the casing to retain the rollers within the lobes. The retainer fits within the limits of movement of a larger diameter section of the roller so that maximum contact is made between the rollers and a smooth stud shaft which is encircled by the casing to any desired extent. The rollers move along the lobes until they lock tight to grip the stud shaft for threading or unthreading. The casing is provided with wrench gripping faces around the exterior. A wrench grips the casing from the side to operate it leaving both ends of the casing open to admit the stud shaft.

  • Patent number: 4607548
    Abstract: Apparatus and method for biasing the handles of a plier-type tool. The tool includes a pair of pivotally connected members, each member having a handle portion and a jaw portion joined together by an interconnecting portion. The interconnecting portions define pivot structure by which the members are rotatably connected and structure for capturing a coil spring that is operative to urge the handles apart. When embodied in an internal retaining plier, the handles are urged towards an equilibrium position. The spring capturing structure in each region comprises a slot defined by a pair of nonconverging arcuate edges joined at one end by a rectilinear edge forming a spring abutment and a spring seat at the other end including a spring retaining tongue.

  • Patent number: 4604918
    Abstract: A stud tensioning apparatus includes an array of arcuate jaw segments that are movable inwardly to cause grooves on the segments to engage the threads of the studs. The tensioning force is applied to the segments by a pull member that has hangers received by apertures in the segments. The hangers fit loosely into the apertures, permitting the segments to move pivotably in two perpendicular directions to compensate for misalignment between the stud and the tensioning apparatus.

  • Patent number: 4605253
    Abstract: A seam roller to be used when installing carpeting which, when used, draws the opposed edges of adjacent runs of carpeting together while applying a downward pressure to tightly bond the carpeting to an adhesive layer. The tool comprises a roller mounting plate having at least two pairs of integrally formed opposed legs bent out of the plane of the mounting plate a first of said pair being generally at right angles to the plane of the plate while a second pair is bent at a predetermined acute angle with respect to the plane of the plate. A first roller assembly is journaled for rotation on an axle extending between the first pair of legs while each of the legs in the other pair supports two flat disc-like washers on independent axles in a parallel and spaced-apart relationship to one another. The respective diameters of the spaced-apart washers rotationally supported on the second pair of legs are such that their peripheries lie in a common horizontal plane.
