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.
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.
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.
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.
