Abstract
Abstract A method and apparatus for mounting a pliable molded sleeve on a combined ferrule and electrical conductor forming an ignition wire for internal combustion engines having a feeding device for depositing a sleeve in a cradle in alignment with a spindle which impales the sleeve. The spindle is provided with a shoulder that pushes the sleeve toward a conductor on the end of which a ferrule has been mounted. The combined conductor and ferrule are held by a plurality of pairs of swinging gates. As the spindle impales the ferrule, compressed air is directed to pass through the sleeve causing it to expand and slide over the ferrule. As the sleeve engages each of the pairs of swinging gates, the gates swing out of the path of the sleeve to permit the sleeve to be properly fitted over the combined conductor and ferrule.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
119 words
The method of mounting a resilient sleeve on a ferrule secured to the end of an electrical conductor comprising gripping said metal ferrule and said conductor at various positions along their length, placing said sleeve in substantial axial alignment with said ferrule, pushing said sleeve toward said ferrule, expanding said resilient sleeve by fluid under pressure, continued pushing of said sleeve over said ferrule and causing said individual gripping forces to swing away from said ferrule and said conductor onto said sleeve in sequence as said sleeve slides over said ferrule and said conductor and discontinuing the flow of fluid under pressure whereby said sleeve resumes its normal size to become firmly positioned on said ferrule and said conductor.
Claim 2
Independent Claim
119 words
The method of mounting a resilient sleeve on a ferrule secured to the end of an electrical conductor comprising gripping said metal ferrule and said conductor at various positions along their length, placing said sleeve in substantial axial alignment with said ferrule, pushing said sleeve toward said ferrule, expanding said resilient sleeve by fluid under pressure, continued pushing of said sleeve over said ferrule and causing said individual gripping forces to swing away from said ferrule and said conductor onto said sleeve in sequence as said sleeve slides over said ferrule and said conductor and discontinuing the flow of fluid under pressure whereby said sleeve resumes its normal size to become firmly positioned on said ferrule and said conductor.
Claim 3
Dependent Claim
48 words
The method as recited by claim 1 and the impaling of said sleeve as said sleeve is pushed toward said ferrule and permitting the escape of said fluid under pressure in said sleeve at the position of the periphery of said sleeve as said sleeve enshroudes said ferrule.
Claim 4
Dependent Claim
123 words
Apparatus for mounting a resilient sleeve on a ferrule connected to the end of an electrical conductor comprising a pair of support means, means pivotally mounting said support means, gripping means for holding said ferrule, means rotatably mounting said ferrule gripping means on said pair of support means whereby said support pivot means compels the swinging of said ferrule gripping means toward and away from said ferrule and said ferrule gripping rotating means permitting the swinging of said ferrule gripping means along an axis of said ferrule, means pushing said sleeve toward and on said ferrule whereby upon the sliding of said sleeve on said ferrule said sleeve engages said ferrule gripping means and causes the latter to swing away from said ferrule.
Claim 5
Dependent Claim
123 words
Apparatus for mounting a resilient sleeve on a ferrule connected to the end of an electrical conductor comprising a pair of support means, means pivotally mounting said support means, gripping means for holding said ferrule, means rotatably mounting said ferrule gripping means on said pair of support means whereby said support pivot means compels the swinging of said ferrule gripping means toward and away from said ferrule and said ferrule gripping rotating means permitting the swinging of said ferrule gripping means along an axis of said ferrule, means pushing said sleeve toward and on said ferrule whereby upon the sliding of said sleeve on said ferrule said sleeve engages said ferrule gripping means and causes the latter to swing away from said ferrule.
Claim 6
Dependent Claim
90 words
The structure as recited by claim 3 wherein said pivot means for said ferrule gripping means comprises a pair of rods rotatably mounted on said support means, a notched member for engaging said ferrule mounted at obe end of each of said rods, a plurality of stop members mounted on said support means, a pin secured to the other end of each of said rods and spring means yieldingly urging said pins into engagement with said stop members when said notched members are extending in a direction toward each other.
Claim 7
Dependent Claim
50 words
The structure as recited by claim 4 wherein said sleeve pushing means comprises an elongated rod for impaling said sleeve, an enlarged portion mounted on said rod engaging said sleeve, said elongated rod having a longitudinal slot along its length permitting fluid under pressure to flow therealong into said sleeve.
