Abstract
A wire puller, especially for pulling a wire (23) through a terminal or connector (25) has a pair of levers (10, 14) connected by a first pivot (11) between a handgrip portion (12) and an abutment portion (13) on one lever (10), the other lever (14) having at least one fixed clamping member (16) and a movable clamping member (18) on a pivot (17), the movable clamping member (18) having a concentric, serrated wire-engaging face (21) and being urged by a spring to close that face (21) to a wire-engaging face (20) on the fixed clamping member (16), and the arrangement being such that opening of the levers (10, 14) causes the abutment portion (13) to open the clamping members (16, 18) for insertion of the wire (23) therebetween, while subsequent closing of the levers (10, 14) causes the clamping members (16, 18) to grip the wire (23) and pull it with respect to the terminal or connector (25) held against the abutment portion (13).

Tllu~, ~ith sucn as wire mesh fenclngr }lorizontal suppo~ strands of wire are provided be.w~en su~port posts and whi~h, after being secured to a ~irst ~ost and c~.rriea to an :- enc~mos~ post, need to be tensioned be'cween the posts. In another instanc:er su~h 2S in the grow incl o~ vines, a consid~rable numb~r o~ hori ont~l s~ nds of wire n~ea _o be provided to provide support ~or the vine~ over their heigh'c.
Again, the lengths of wire are secured ~co 2 rir~t yos~ ~nd -carried to an enamost post, s7ith the n~ed rOL t}le lens~:hs or t~ire to be ~ensioned be~ween the posts. The wires ma~ be se~ured in tension by ~ncho~ing ~o the endm~st post; or th~

Claims (8)
1. A wire puller comprising a first lever having a first pivot between a handgrip portion and an abutment;
portion, a second lever pivoted by the first pivot to the first lever between a handgrip portion of the second lever and a first clamping member on at least one side of the second lever, a second pivot on the second lever between the first pivot and the first clamping member, a second clamping member on the second pivot on at least the same side of the second lever as the first clamping member, the second clamping member being spring-loaded to a stop position towards the abutment portion of the first lever, and first and second wire-engaging faces on the first and second clamping members respectively, the second wire-engaging face being arcuate but non-concentric with the second pivot and whereby as the second clamping member is urged towards its stop position the minimum gap between the first and second wire-engaging races diminishes, the abutment portion having a first abutment face adapted to press against the second clamping member when the handgrip portions of the levers are moved away from each other so as to increase the minimum gap between the wire-engaging faces for insertion therebetween of any wire up to a maximum diameter, and the abutment portion having a second abutment face racing appositely to the first abutment face for abutment by a terminal or connector with respect to which the wire is to be pulled when the handgrip portions of the levers are moved towards each other.
portion, a second lever pivoted by the first pivot to the first lever between a handgrip portion of the second lever and a first clamping member on at least one side of the second lever, a second pivot on the second lever between the first pivot and the first clamping member, a second clamping member on the second pivot on at least the same side of the second lever as the first clamping member, the second clamping member being spring-loaded to a stop position towards the abutment portion of the first lever, and first and second wire-engaging faces on the first and second clamping members respectively, the second wire-engaging face being arcuate but non-concentric with the second pivot and whereby as the second clamping member is urged towards its stop position the minimum gap between the first and second wire-engaging races diminishes, the abutment portion having a first abutment face adapted to press against the second clamping member when the handgrip portions of the levers are moved away from each other so as to increase the minimum gap between the wire-engaging faces for insertion therebetween of any wire up to a maximum diameter, and the abutment portion having a second abutment face racing appositely to the first abutment face for abutment by a terminal or connector with respect to which the wire is to be pulled when the handgrip portions of the levers are moved towards each other.
2. A wire puller as in Claim 1, wherein the abutment portion of the first lever is provided with a notch for location of a wire extending from a terminal or connector to between the clamping members on the second lever, whereby the terminal or connector is located against the second abutment face.
3. A wire puller as in Claim 1 or Claim 2, wherein the second abutment face is recessed for receipt of one end of a terminal or connector.
4. A wire puller as in any one of Claims 1 to 3, wherein the other size of the second lever is also provided with first and second clamping members, so that the wire puller can be used either way round
5. A wire puller as in any one of Claims 1 to 4, wherein both levers have a U-section, with the abutment portion formed as a first separate solid component riveted between the limbs of the U-section of the first lever, and with the first clamping member or members formed integrally with a second separate solid component riveted between the limbs of the U-section of the second lever.
6. A wire puller as in any one or Claims 1 to 5, wherein the handgrip portion of each lever is fitted with a resilent sleeve forming the handgrip proper.
7. A wire puller as in Claim 5, wherein the second level is provided with a stop portion cooperating with the inside base of the U-section of the f first lever to limit closure of the levers.
8. A wire puller substantially as hereinbefore described with reference to the accompanying drawings.
