The shell is an elongated open ended member that is tapered in length and is formed with a U shaped cross section, sized to receive the wedge in sliding engagement. The wedge has a shim fixed to its lower side with a surface shaped to frictionally engage the upper surface of a cable positioned within the shell and press it against a friction surface forming the bottom of the shell. A bail engages the wedge and shim to pull the wedge into operative engagement with the shell and a segment of cable extending through the shell.

  • Publication number: 20020117371
    Abstract: The invention relates to a shaft-hub-connection with a shaft having an external face portion seating in a first bore portion (6) of the hub (3). A tensioning screw (19) is provided with a head which is supported on a support disk (11). The disk is non-movably held in an axial direction on the hub (3), in the tensioned condition where the threaded shank (22) sits in the threaded bore (18) of the shaft (14). A nut (23) is between the support disk (11) and the shaft (14). The nut (23) is on the threaded shaft (22). This nut (23) is non-movably retained on the shank. When actuating the tensioning screw (19) in a disconnecting direction the nut (23) abuts the support diskk (11), so that the hub (3) and the shaft (14) move away from each other and become separated.

  • Patent number: 6406210
    Abstract: A novel captivated jackscrew structure is characterized by the formation of both an internal cavity (15) within one of the two bodies that are to be connected together and an access passage (17). One end of the cavity, located at one end of the body is open. The small diameter access passage extends through the other end of the body into the cavity's other end. A standard machine screw (1) is installed head (3) first and captured within the cavity, with the screw shaft (5) protruding from the end of the body (20). A barrier (7) is provided to prevent withdrawal of the machine screw head, but permit the screw head and shaft to move a limited distance axially within the cavity. A backstop (9), resembling an inverted cup with a hole in the bottom lies in inverted position in the cavity over the screw's head.

  • Patent number: 6298534
    Abstract: The present invention generally provides an apparatus and a method for separating components of a processing system which are mounted to one another and may adhere after being subjected to processing conditions. In one aspect, the invention provides a removal screw that can be threaded into a removal hole on a first component and an abutment screw that can be threaded into an attachment hole on a second component. To separate the first component from the second component, the abutment screw is first threaded into the attachment hole on the second or stationary component, and then the removal screw is threaded into the removal hole on the first component. An important aspect of this invention is that the removal screw does not contact, and damage, the contact surface between the first and second components to separate the components.

    Abstract: The invention is directed to a retaining ring for securing components along a shaft by transferring the compression load between the components, thereby preventing the adjacent components from separating. The retaining ring includes a pair of arcuate interlocking members having a first end, a second end, an inner wall and an outer wall. The outer wall includes a first surface and the inner wall includes a second surface thereby defining a thickness between the first surface and the second surface. The inner wall also includes a third surface thereby defining a thickness between the third surface and the first surface, wherein the thickness between the third surface and the first surface is less than the thickness between the second surface and the first surface. The inner wall also includes a fourth surface joining the second surface and the third surface to define a smooth transition therebetween.

  • Patent number: 5678945
    Abstract: A detent mechanism that acts between two components that rotate with respect to one another to control rotation from a first set position to at least a second set position. The detent mechanism (10) comprises at least one rotating cam (23) positioned between adjacent surfaces of two components (11 and 16). The cam (23) is spaced from the axis of rotation of the two components (11 and 16). The cam (23) is journalled for rotation on one of the components (11) about an axis that is substantially transverse to the axis of rotation between the two components (11 and 16). The operating surface (25) of the cam (23) comprises at least one cam lobe that is caused to rotate as the two components (11 and 16) rotate. The cam (23) acts to separate the two components (11 and 16). Spring (17) acts to urge the adjacent surfaces together so that a predetermined torque is required to cause relative rotation between the components (11 and 16).
