Abstract
Abstract A winterized control cable composed of an inner cable slidable in an outer tube is provided with at least one heat generating wire for preventing water droplets between the inner cable and the outer tube from freezing and to prevent the lubricant filling between the cable and tube from solidifying. The heating element or elements can be disposed in either the inner cable or the outer tube. Alternatively the heating element or elements can be disposed between an outer covering and the outer surface of the tube or between a plastic sleeve housed in the tube and the inner surface of the tube. The control cable disclosed is particularly use for remote control of clutch, throttle, brake and the like of automobiles and snowmobiles.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
A control cable comprising an outer tube, an inner cable slidably extending through said outer tube and a heat-generating wire means, wherein the tube has a relatively large wall thickness and the heat-generating wire means is at least a single wire embedded in the wall of said tube and helically wound longitudinally along substantially the entire extent of said outer tube, and means for connecting the heat-generating wire means in circuit with an energization source, whereby said heatgenerating wire means conveys current from an energization source to produce heat in said outer tube to preclude moisture formation and freezing between said outer tube and inner cable.
Claim 2
Dependent Claim
106 words
A control cable comprising an outer tube, an inner cable slidably extending through said outer tube and a heat-generating wire means, wherein the tube has a relatively large wall thickness and the heat-generating wire means is at least a single wire embedded in the wall of said tube and helically wound longitudinally along substantially the entire extent of said outer tube, and means for connecting the heat-generating wire means in circuit with an energization source, whereby said heatgenerating wire means conveys current from an energization source to produce heat in said outer tube to preclude moisture formation and freezing between said outer tube and inner cable.
Claim 3
Dependent Claim
40 words
A control cable according to claim 1, wherein said outer tube comprises an outer covering, a coiled steel wire tube extends through said outer covering and said heat-generating wire means is interposed between them and covered with an insulating material.
Claim 4
Dependent Claim
48 words
A control cable according to claim 1, wherein said outer tube comprises a coiled steel wire tube externally covered with an insulating material, a plastic sleeve extends through said coiled steel wire tube and said heat-generating wire means is interposed between them and covered with an insulating material.
Claim 5
Dependent Claim
46 words
A control cable according to claim 1, wherein said outer tube comprises a coiled steel wire tube, a two-layered outer covering houses therein said coiled wire tube and said heat-generating wire means comprises a bare heat-generating wire interposed between the two layers of said outer covering.
Claim 6
Dependent Claim
41 words
A control cable according to claim 1, wherein said outer tube comprises a tube made of an insulating material, said heat-generating wire means is embedded in the wall of said tube and a coiled steel wire tube extends through said tube.
Claim 7
Dependent Claim
38 words
A control cable according to claim 1, wherein said outer tube comprises a plurality of steel wires, at least one of which comprises said heat-generating wire means, said at least one wire being covered with an insulating material.
Claim 8
Dependent Claim
133 words
A control cable including an outer tube and an inner cable slidably extending through said outer tube, said outer tube being made of an insulating material, a heat-generating wire means being embedded in the wall of said outer tube, wherein the tube has a relatively large wall thickness and the heat-generating wire means is a plurality of wires positioned in parallel to each other and embedded in the wall of said tube in a helical arrangement with a small inclination and substantially coextensive with said outer tube, and means for connecting the heat-generating wire means in circuit with an energization source whereby said plurality of heat-generating wires convey current from an energization source to produce heat in said outer tube to preclude moisture formation and freezing between said outer tube and inner cable.
Claim 9
Dependent Claim
133 words
A control cable including an outer tube and an inner cable slidably extending through said outer tube, said outer tube being made of an insulating material, a heat-generating wire means being embedded in the wall of said outer tube, wherein the tube has a relatively large wall thickness and the heat-generating wire means is a plurality of wires positioned in parallel to each other and embedded in the wall of said tube in a helical arrangement with a small inclination and substantially coextensive with said outer tube, and means for connecting the heat-generating wire means in circuit with an energization source whereby said plurality of heat-generating wires convey current from an energization source to produce heat in said outer tube to preclude moisture formation and freezing between said outer tube and inner cable.
