摘要： PURPOSE:To surely carry out imprinting independently of the dimension of the projection length of a screw from a nut which completes tightening, by installing a lever device which can press down a leaf spring for the urging of the rise of a printing rod, by the action of a toggle link in a pipe. CONSTITUTION:When the tightening torque due to a wrench 1 reaches a certain value, a toggle link 9 in a tilt state is turned in the axis line direction of a pipe 7 by the toggle action of the toggle link 9, and the projection formed on a lever 1b is pressed upward. Owing to the displacement of the toggle link 9, also the lever 1b is shifted, and a lever 14 is turned in the clockwise direction through a bolt 15, and a leaf spring 8 is pressed down. Accordingly, a printing rod is lowered sharply, and performs printing at the end part of the bolt. Accordingly, when tightening completes, the end part of the bolt can be imprinted and colored automatically.

摘要： PURPOSE:To keep off such a fear of unreeving by installing a radial pull arm and a guide arm in a base frame and a movable frame respectively, and forming each inner surface of these arms being opposed in making both these frames overlapped, into a stepped form so as to cover both the side edges. CONSTITUTION:A pulley center shaft 2 is projected into a base part of a base frame 1 while a pull arm 1a and each guide arm 1b at both sides are projected in the radial direction from the base part. An engaging part M is installed in a radial position of each end of these arms 1a, 1b. A movable frame 4 is provided with a pull arm 4a and a guide arm 4b corresponding to the base frame 1, and it is pivotally supported at the outside of the pulley being inserted into the center shaft 2 while it is provided with an engaging edge N engaging the engaging part M, through which a closed space is made so as to be formed at the upper part when being overlapped. Each opposed side of this space is formed into a stepped surface which is made so as to cover both side edges of the pulley. Consequently, with a movable arm 4 rotated, a rope is removable, and that such a fear of unreeving is brought to nothing.

摘要： PURPOSE:To prevent runaway of wire by providing a ratchet type engaging section engageable with a frame body to allow self-weight approach to pulley side and a wedge member for gripping the wire on a guide rail to the guide rail having an inclining slide face and fixed to the frame body. CONSTITUTION:When a metal wheel is turned over upside down, the guide rail 5 of a lowering hanging wheel 1 lowers together with a wedge member 13 through self-weight and approaches to a pulley 3. At this time, ratchet type engaging sections 9, 12 allow relative lowering of the guide rail 5 with no trouble. When the guide rail 5 lowers, the wedge member 13 contacts with a wire. When the free end of the wire starts to run on the pulley 3, the wedge member 13 moves along the inclining slide face 6 of the guide rail 5 through friction and pulled in between the wire and the guide rail 5 thus holding the wire between the wedge member 13 and the pulley 3. By such arrangement, runaway of wire can be prevented.
