Abstract: A connector or locking device for wires (or wire ropes) W has a body (20) of alloy, two channels (21) within the body, entry ends (23) at opposite ends for wires, and wedges (25) within the body urged by springs (26) towards the entry ends (23) and to protrude into the channels (21) for the purpose of gripping inserted wires and preventing their withdrawal in the opposite direction to insertion, and is characterized in that guideways (30) are formed within the body (20) alongside each channel from adjacent its entry end (23) to beyond its wedge (25), and plastics slide (31) are fitted one within each of the guideways each with its inner end (32) overlapping a nose part (33) of the respective wedge and its outer end (34) protruding outwards beyond the entry end of the channel, retention means (35, 36) being provided between each slide (31) and its guideway (30) while allowing inward sliding to push the wedge (25) against the urge of its spring (26) when the outer end (34) of the slide is pushed relative to the

Abstract: A tool for pulling a wire (W) through a connector (C) or a terminal has a pair of levers (20, 24) pivoted together, one lever (20) having an abutment portion (23) for location of the connector (C) and the other lever (24) having clamping members (26, 28) for gripping the wire (W), characterised in that one lever (24) has a handgrip portion (25) articulated to a shank portion (40) for movement between an in-line position and a position inclined towards the handgrip portion (22) of the other lever (20), spring-loaded latching means (45) being provided between the handgrip portion (25) and the shank portion (40) for disengagement when the tension in the wire (W) reaches a value set by a knob (72) for loading the spring means and indicated by a pointer (73) against a scale (74).

Abstract: A wire termination device (24) of the type having a body (25) with a first through-bore (26) into which protrudes wedging means (27) urged by spring means (28) and having a second through-bore (33) without wedging means, is characterised in that the second through-bore (33) is interrupted by a transverse notch (34), and each body portion (35A, 35B) separated by the notch (34) has a longitudinal entry slot into the second through-bore (33) with the slot (36A) in one portion (35A) at the opposite side of the body (25) to the slot (36B) in the other portion (35B), whereby the device (24) can be affixed for a horizontal wire (37) of a stock-fence by presenting the notch (34) to the wire (37) and then turning the device (24) so as to enable the wire (37) to pass through both slots (36A, 36B), whereafter a free end (38) of the wire (37) can be inserted into the first through-bore (26) after passing round an end post (39) to be secured in the device (24) by the wedging means (27).

Abstract: A mechanism for suspending equipment from an overhead structural member includes a suspension strand, e.g. of wire or wire rope, provided at one end with a screwthreaded portion, together with a locking device having in bores each preferably associated with a wedging mechanism which prevents withdrawal of the free end of the strand in the opposite direction to insertion. The screwthreaded portion may be screwed into the overhead structural member, or into the equipment, the free end of the strand passed through one bore of the locking device, through an eye on the equipment or round the equipment, or through an eye on the overhead structural member or round the overhead structural member, then back through the other bore of the locking device to be secured therein by the wedging mechanism.

Abstract: A wire clamping device including a body, at least one bore through the body for an end of a wire and at least one channel in the body converging at an acute angle and into communication with the bore towards an inlet end of the bore. An abutment is at an end of the channel remote from the inlet end of the bore, and a wedge is movable along the channel between the abutment and a region of communication with the bore. A face of the wedge facing the abutment is provided with an undercut groove, and a hole is provided through the abutment for passage therethrough of a rod-like tool provided with diametrically opposed projections at one end for pulling engagement with the undercut groove by partial rotation of the tool from an insertion position.

Abstract: A method of suspending equipment (40) from an overhead structural member (37) comprises providing a first eye (36) on the overhead member (37), providing a suspension strand (20) with a loop (21) at one end, passing the other, free, end (38) of the strand (20) through the eye (36) and through the loop (21), passing the free end (38) of the strand (20) through one bore (24A) of a locking device (23) of the type having twin bores at least one of which is associated with wedging means preventing withdrawal in the opposite direction to insertion, providing a second eye (39) on the equipment (40) to be suspended, passing the free end (38) of the strand (20) through the eye (39) on the equipment (40), and passing the free end (38) of the strand (20) through the other bore (24B) of the aforesaid device (23).

Abstract: A connector for wires comprises a body (20) having through passage (21) adapted to receive a pair of oppositely directed wire end portions (22A, 22B) in close lengthwise relationship with each other, channels (23A, 23B) within the body (20) one to each side of the through passage acutely inclined to and, at their inner ends, breaking into the through passage, and wedge structure (24A, 24B) within the channels adapted upon attempted withdrawal of either of the wire end portions (22A, 22B) from the through passage (21) to urge the wires therebetween forcibly towards each other, whereby friction secures them firmly in the connector.
