Abstract
Abstract A pair of blocks each having a conveyor and gripping jaws on the latter are provided such that one of the blocks is movable from the other. A carrier having a cramp is moved between the both blocks and is cooperated with the blocks such that when the carrier acts against the movable block and the immovable block, the cramp is opened and closed, respectively.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
264 words
An apparatus for severing a wire drawn from continuous wire stock to a predetermined length and delivering the severed wire to conveyer, said apparatus comprising: a pair of movable and immovable opposite blocks (1,2) each having a periodically and successively rotated conveyer means gripping jaws of a pair on the opposite conveyer means being faced with each other in alignment; a carrier means (10) movable in the direction perpendicular to the conveyer moving direction, said carrier means comprising a lower carrier member (11) reciprocable for a predetermined length and an upper carrier member (12) placed upon said lower carrier member to be slidable relative to the latter in the reciprocating direction of said lower carrier member, said upper carrier member having a clamp (30) for drawing the wire from the continuous wire stock through said gripping jaws at a wire severing and delivery zone while said gripping jaws are open; means (40) for stopping the movement of said upper carrier member in cooperation with a stopper member (41) secured to said movable block while said lower carrier member is moving forwardly; means for opening said clamp by advancing movement of said lower carrier member while the movement of said upper carrier member is stopped; means for retreating said carrier means after said clamp has opened, said retreating means closing said clamp at the most retreated position of said carrier means; means (50) for closing said gripping jaws locating at said wire severing and delivery zone just before said clamp is open; and wire severing means provided near the most retreated position of said clamp.
Claim 2
Independent Claim
264 words
An apparatus for severing a wire drawn from continuous wire stock to a predetermined length and delivering the severed wire to conveyer, said apparatus comprising: a pair of movable and immovable opposite blocks (1,2) each having a periodically and successively rotated conveyer means gripping jaws of a pair on the opposite conveyer means being faced with each other in alignment; a carrier means (10) movable in the direction perpendicular to the conveyer moving direction, said carrier means comprising a lower carrier member (11) reciprocable for a predetermined length and an upper carrier member (12) placed upon said lower carrier member to be slidable relative to the latter in the reciprocating direction of said lower carrier member, said upper carrier member having a clamp (30) for drawing the wire from the continuous wire stock through said gripping jaws at a wire severing and delivery zone while said gripping jaws are open; means (40) for stopping the movement of said upper carrier member in cooperation with a stopper member (41) secured to said movable block while said lower carrier member is moving forwardly; means for opening said clamp by advancing movement of said lower carrier member while the movement of said upper carrier member is stopped; means for retreating said carrier means after said clamp has opened, said retreating means closing said clamp at the most retreated position of said carrier means; means (50) for closing said gripping jaws locating at said wire severing and delivery zone just before said clamp is open; and wire severing means provided near the most retreated position of said clamp.
Claim 3
Dependent Claim
64 words
An apparatus as claimed in claim 1, wherein said stopping means (40) comprises a cam plate (41) attached to said movable block (2), and a lever assembly (44, 47, 91, 92) having a pivotable lever provided with a roller (42) cooperable with said cam plate, said lever being inclined as said roller (42) advances along said cam plate and stopping said upper carrier member.
Claim 4
Dependent Claim
85 words
An apparatus as claimed in claim 1, wherein said stopping means (40) comprises an L-shaped lever (82) pivoted to said movable block (2) and having a pin (84) at its free end, and a lever (86) also pivoted to said movable block and having an hook (88) engageble with said pin on said L-shaped lever, said L-shaped lever (82) having another free end (85) cooperable with said upper carrier member, said other lever (86) having a free end (89) cooperable with said lower carrier member.
Claim 5
Dependent Claim
86 words
An apparatus as claimed in claim 2, wherein said lever assembly comprises an L-shaped lever (44) pivoted to said lower carrier member (11) and having the roller (42) at its one free end, another lever (47) pivoted at its one end with the other free end of said L-shaped lever and at its other end with said upper carrier member (12), and a tension spring (46) provided between said lower carrier member (11) and the pivotal portion of said L-shaped lever (44) and other lever (47).
Claim 6
Dependent Claim
107 words
An apparatus as claimed in claim 2, wherein said carrier means (10) further comprises an intermediate carrier member (90) slidably disposed between said upper and lower carrier members (11, 12), said intermediate carrier member being operatively connected with said lower and upper carrier members through tension springs (94) and (95), respectively; said lever assembly comprises a first link 91 pivoted at its one end with said lower carrier member (11) and a second link 92 pivoted at its one end with said intermediate carrier member (90), said both links being pivoted with each other at their other ends and having the roller (42) at their pivoted junction.
Claim 7
Dependent Claim
68 words
An apparatus as claimed in claim 2, wherein said cramp operating means comprises a J-shaped cramp plate (31), an L-shaped cramp plate (31a), and a T-shaped leVer (32), said J-shaped and L-shaped cramp plates being biased to the closing position by a spring (64) and having foot portions pivoted to both arms (37, 37) of said T-shaped lever, said T-shaped lever being operatively connected to said lever assembly.
Claim 8
Dependent Claim
18 words
An apparatus as claimed in claim 1, wherein said conveyers (4, 4a) are each made of rigid disk.
Claim 9
Dependent Claim
49 words
An apparatus as claimed in claim 1, wherein each of said gripping jaws (3, 3a) comprises a pair of jaw members (101, 101a, 112, 112a), and a spring (109, 117) serving to close and open said jaw members, said jaw members being opened and closed against the spring force.
