Abstract
Abstract This invention relates to improved apparatus for the automatic calibration of cables of the type having a core wire and surrounding sheath. Such cables are commonly used in automobiles to transfer motion from a controlling member to a controlled member at a distant point which is moved in accordance with the force applied at the first member. A calibration apparatus is described which is fixedly attached to the cable sheath and comprises a rack section and a comb section which interact when force is applied to change the sheath length to that desired.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A cable calibration device for a cable comprised of a core wire and surrounding sheath, comprising: a. a rack section with teeth thereon fixedly mounted on said sheath; and b. a comb section with teeth thereon also mounted on said sheath, said teeth on the comb section being biased in engagement with the teeth on the rack section to secure said rack section to said comb section, the teeth so shaped that a force above the design load of the cable would cause the teeth on the rack and comb sections to move over each other in either of two opposite directions thereby shortening or lengthening the sheath to calibrate the cable.
Claim 2
Dependent Claim
112 words
A cable calibration device for a cable comprised of a core wire and surrounding sheath, comprising: a. a rack section with teeth thereon fixedly mounted on said sheath; and b. a comb section with teeth thereon also mounted on said sheath, said teeth on the comb section being biased in engagement with the teeth on the rack section to secure said rack section to said comb section, the teeth so shaped that a force above the design load of the cable would cause the teeth on the rack and comb sections to move over each other in either of two opposite directions thereby shortening or lengthening the sheath to calibrate the cable.
Claim 3
Dependent Claim
21 words
The device of claim 1 wherein the rack section is a male section and the comb section is a female section.
Claim 4
Dependent Claim
37 words
The device of claim 1 wherein the teeth of the comb section are mounted in pairs offset one to the other by one half of the distance between the peaks of the teeth on the rack section.
Claim 5
Dependent Claim
34 words
The device of claim 3 wherein the comb section has a plurality of legs, each leg having a free end portion, said teeth of the comb section are mounted at each respective end portion.
Claim 6
Dependent Claim
12 words
The device of claim 4 wherein the plurality of legs is 4.
