Abstract
Abstract A wire stripping apparatus is provided which comprises a rotatable member supported by a carrier, a slide member mounted on the axle of the rotatable member, and cooperable stripping blades mounted to the head portion of the rotatable member, the stripping blades being closed to sever an insulation of a wire when the slide member moves forwardly at the most advanced position of the carrier and being opened when the slide member moves back at the most retreated position of the carrier.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
209 words
Wire stripping apparatus comprising: a supporting base plate 10 on which a pair of protuberances 11, 12 are provided; carrier means 20 provided upon said supporting base plate for reciprocation in the direction parallel to the axis of an insulated wire to be stripped; a rotatable member 40 having a head portion 41 connected to an axle 42 thereof, said rotatable member 40 being supported by said carrier; a slide member 55 slidably mounted on said axle of said rotatable member to take an advanced position and a retracted position; cooperable stripping blades 51, 51 mounted to said head portion of said rotatable member to take a closed position to sever the insulation and an open position in cooperation with the advance and the retract of said slide member; means 60 connected with said carrier means and cooperated with said protuberances for operating said slide member, said slide member operating means maintaining said slide member to the advanced position while said carrier means is at the most advance position and is retreating therefrom and maintaining said slide member to the retracted position while said carrier member is at the most retreated position and is advancing therefroM; and means 80 for setting the most advanced position of said slide member.
Claim 2
Dependent Claim
209 words
Wire stripping apparatus comprising: a supporting base plate 10 on which a pair of protuberances 11, 12 are provided; carrier means 20 provided upon said supporting base plate for reciprocation in the direction parallel to the axis of an insulated wire to be stripped; a rotatable member 40 having a head portion 41 connected to an axle 42 thereof, said rotatable member 40 being supported by said carrier; a slide member 55 slidably mounted on said axle of said rotatable member to take an advanced position and a retracted position; cooperable stripping blades 51, 51 mounted to said head portion of said rotatable member to take a closed position to sever the insulation and an open position in cooperation with the advance and the retract of said slide member; means 60 connected with said carrier means and cooperated with said protuberances for operating said slide member, said slide member operating means maintaining said slide member to the advanced position while said carrier means is at the most advance position and is retreating therefrom and maintaining said slide member to the retracted position while said carrier member is at the most retreated position and is advancing therefroM; and means 80 for setting the most advanced position of said slide member.
Claim 3
Dependent Claim
100 words
Wire stripping apparatus as claimed in claim 1, wherein said rotatable member 40 has a cylindrical recess 43 formed at the front center portion of said head portion 41 and a pair of; grooves 45, 45 in the annular wall portion 44 excircling said recess, said grooves being parallel to the axis of said rotatable member; said cooperable stripping blades 51, 51 are connected to the front ends of pivotable levers 52, 52 provided in said grooves 45, 45, respectively; and said slide member 55 has a tapered end portion 56 against which the rear ends of said levers abut.
Claim 4
Dependent Claim
106 words
Wire stripping apparatus as claimed in claim 1, wherein said rotatable member 40 has a cylindrical recess 43 formed at the front center portion of said head portion 41 and a pair of grooves 45, 45 in the annular wall portion 44 encircling said recess, said grooves being parallel to the axis of said rotatable member; said cooperable stripping blades 51, 51 are connected to the front ends of pivotable levers 52, 52 provided in said grooves 45, 45, respectively; and said slide member 55 has slant grooves 59, 59 with which pins 58, 58 provided at the rear portions of said levers 52, 52 engage.
Claim 5
Dependent Claim
219 words
Wire stripping apparatus as claimed in claim 1, wherein said slide member operating means comprises a spring means 61 forwardly urging said slide member 55, a lever 62 pivotably connected to said carrier means 20, said lever having a lower end 66 cooperable with said protuberance 12 provided at the rear portion of said supporting base plate 10 and an upper end 64 cooperable with said slide member, said upper end of said lever retracting said slide member against and spring means when said lower end of said lever acts against said protuberance as said carrier mean is retreated, and a hook member 67 pivotably connected to said carrier means 20, said hook member 67 having a fore end 71 cooperable with the protuberance 11 provided at the fore portion of said supporting base plate 10 and a rear end portion 70 engageable with a pin 69 provided at said lever, said hook member partially rotating in the direction to release the engagement between said rear end portion and said pin when said fore end of said hook member acts against said front protuberance as said carrier means advances, said rear end portion of said hook member engaging with said pin when said lower end of said lever acts against said rear protuberance as said carrier means is retreated.
Claim 6
Dependent Claim
92 words
Wire stripping apparatus as claimed in claim 1, wherein said setting means 80 of the most advanced position of said slide member comprises a hollow member 81 opened at its rear portion and fixed to said carrier means 20, said hollow member having a horizontal slit 82 continued to the rear end thereof, a stopper 85 of a lock nut screwed to threads on the outer surface of said hollow member, and a member 65 projecting from said slide member to pass through said slits and to be collidable with said stopper.
Claim 7
Dependent Claim
41 words
Wire stripping apparatus as claimed in claim 1, wherein said setting means 80 of the most advanced position of said slide member comprises a frame-like stopper 86 movably connected to said carrier means 20 to restrict inclination angle of said lever.
