Abstract
Abstract A motion transmitting remote control assembly comprising a flexible conduit having an anchor fixedly attached to at least one of its ends, the conduit is attached at its anchor members to frame members, motion transmitting members operatively connected to the frame. A core is axially movable in the conduit and is operatively connected to the motion transmitting members. The anchor engages the frame to prevent rotational movement thereof. A tension adjusting device contacts the frame and engages the anchor to axially move the anchor to change the distance between the motion transmitting members to thereby adjust the tension in the core.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
A manually operated pull-pull cable control assembly having reduced backlash comprising an input shaft, a small diameter pinion gear driven by said input shaft, a large diameter gear driven by said pinion gear, a first large diameter rotatable pulley operatively connected to said large diameter gear, a second pulley mounted for rotation on an output shaft spaced from said first pulley, a flexible double conduit cable hose interposed between said first and second pulleys, and two flexible cable cores movably disposed in said hose with adjacent ends of said cable cores being respectively attached to said first and second pulleys so that longitudinal movement of one cable core in one direction is accompanied by longitudinal movement of the other cable core in the opposite direction in said hose, the maximum length of movement of one cable core being substantially equal to the circumference of said first pulley.
Claim 2
Dependent Claim
147 words
A manually operated pull-pull cable control assembly having reduced backlash comprising an input shaft, a small diameter pinion gear driven by said input shaft, a large diameter gear driven by said pinion gear, a first large diameter rotatable pulley operatively connected to said large diameter gear, a second pulley mounted for rotation on an output shaft spaced from said first pulley, a flexible double conduit cable hose interposed between said first and second pulleys, and two flexible cable cores movably disposed in said hose with adjacent ends of said cable cores being respectively attached to said first and second pulleys so that longitudinal movement of one cable core in one direction is accompanied by longitudinal movement of the other cable core in the opposite direction in said hose, the maximum length of movement of one cable core being substantially equal to the circumference of said first pulley.
Claim 3
Dependent Claim
89 words
A remotely operated control system for applying variable torque to a pivotally movable member comprising a motion input means, flexible cable meaNs operatively connected to transmit motion in response to movement of said input means, rotatable means operatively driven by said cable means to rotate in response to movement of said cable means, and torque application means operatively connected to said rotatable means and to said pivotally movable member, said torque application means varying the torque applied to said member in response to rotational movement of said rotatable member.
Claim 4
Dependent Claim
89 words
A remotely operated control system for applying variable torque to a pivotally movable member comprising a motion input means, flexible cable meaNs operatively connected to transmit motion in response to movement of said input means, rotatable means operatively driven by said cable means to rotate in response to movement of said cable means, and torque application means operatively connected to said rotatable means and to said pivotally movable member, said torque application means varying the torque applied to said member in response to rotational movement of said rotatable member.
