Spaced parallel guide rods 15 and 16 extend from top to bottom frame walls and two spaced cross-members 17 and 18 extend between the sidewalls.
First and second pulley blocks 20 and 21, are mounted for sliding movement on the rods 15 and 16. The first pulley block carries a first and third series of pulleys 22 and 23, respectively the pulleys of each series being mounted for independent individual rotation on a common axis and the second block carries a second series of pulleys 24 similarly mounted. The blocks are linked by two chains 27, 28 which pass round idler gears 29 and 30 respectively mounted in the top and bottom walls. A double acting piston and cylinder drive means 32 is fixed on the cross-members and operatively engages the pulley block 21. A fourth and fifth series of pulleys 33 and 34 are each fixed for rotational movement on respective common axes on the side walls 11 and 12, respectively. An output nip 35 comprises a series of roller pairs, the rollers of each pair being individually spring biased together to accommodate different wire sizes and is mounted on a block extending from the sidewall 12. The nip is linked by a gear train 37 and a ratchet or one-way clutch (not shown) to the chain 27.
In operation of the apparatus, a series of wires from storage reels are looped around the pulleys as shown and located in the output nip. The pulley blocks are adjacent the cross-member 17 as shown in Figures 2 and 3.
Operation of the piston and cylin~er drive pushes block 21 away from .

~ 1093~z ' the cross-member and block 20 is drawn a corresponding distance by chain 28. The spreading of the blocks draws a predetermined length of wires simultaneously from their storage reels as the other ends of the wires are held by the nips 35. Subsequent operation of the piston and cylinder in the opposite sense draws the block 21 towards ; the cross-member 17 and similarly block 20 by chain 27.
At the same time, chain 27 drives output nip 35 through gear train 37 at a rate appropriate to draw off the lengths of wires corresponding to the lengths previously drawn from the storage reels.
The above described apparatus is particularly suitable for use with the harness making apparatus 102 shown in , Figures 4 and 11 and described more fully in our Canadian Application Serial No. 306,861 filed July 6, 1978 and to which attention is directed. In the apparatus, a head 91 holding one end of the wires 59 transverses from an operating station 93 adjacent the nip 81 to a distal station 94 drawing the wires from the nip, terminates that end of the wires in a connector 98 and 99 at that station, and returns to the station 93 adjacent the nip for a dwell period in which measured lengths of wires 59 are fed by .f the nip past or through the head to extend in slack condition between the stations and terminated at their other end in connectors 103, 100 at the adjacent station.
This arrangement enables wire harnesses of greater length than the separation of the stations to be manufactured.

~695 The measuring part of the operative cycle may largely occur during the return of the head from the distal to the adjacent station reducing the dwell period facilitating speed of operation of the apparatus.
In the second example of apparatus 41, Figures 4 to 10, five pulley assemblies 43,44 are provided, two assemblies 43 mounted for movement together on an upper movable pulley block 45 and three assemblies 44 on a lower movable pulley block 46, enabling a reduction in the overall height of the apparatus 41 in relation to the lengths of wires measured compared with the first example. Means are provided to alter the lengths of wires measured and, as shown in Figure 5, the means may comprise a first micro-switch 47 mounted on a stop block 48 mounted for movement along a threaded column 49 adjacent the path of movement of the upper pulley bloc]c 45 by handle 38. Towards the ~o B end of the wire measur~ng step a cam ~on the upper block engages the first micro-switch causing control circuitry to xeduce the fluid supply to an operating cylillder to retard the uppex block 45 and a lug Sl on the pulley block subsequently engages the stop block 48 to prevent further separation of the pulley blocks 45,46.
A second micro-switch 52 is mounted on the stop block 48 at a location spaced fxom tha first micro-switch and :~
engageable by a second cam 53 on the upper bloc]c 45 during a first stage of movement of the blocks 45,46 towards one another. The switch 52 is arranged to operate ,. ~ .

patent applicationr~ th~ 6~e ~tc (~78~t where control circuitry reactivates tlle operating piston to drive the pulley blocks fully towards one another and the drive to the output nip to complete the wire feed.
The output nip 81 ~Figure 6) comprises co-operating roller assemblies 54,55 having individually rotatable rollers 56,57. The individually rotatable rollers 57 of the lower roller assembly 55 are connected for movement together on a common shaft 60 by annular friction clutch plates 39 located on the shaft between the individual rollers. The clutch plates 39 transmit axial thrust but permit slip of an individual roller in the event of resistance from its associated wire 59 resulting from complete feed of that wire. The individually rotatable rollers 56 of the other, upper roller assembly 54 of the output nip are each biased by an individual pneumatic piston and cylinder assembly 58 towards the co-operating roller thereby maintaining a nip pressure on the respective wires 59 which is substantially independent of wire diameter. The individual pistons and cylinders 58 are located in staggered relation in a cylinder block assembly 40 to permit high density of pac]cing.

A wire clamp (Figures 7 and 8) i5 located between the idler pulley assembly 80 and the nip 81 and comprises a series of wixe engaging fingers 82 individually biased by springs 61 in housin~ 62 against individual wires 59.
~ lin wire-locking piston and cylinder assemblies 83 are provided to advance the spring housing 62 against the fingers 82 simultaneously, to clamp the wires 59 against a bar 84 at the end of each wire feed operation to prevent wires being pulled from the wire clamp or holding head 91 particularly during a wixe measuring operation.
A wire lockiny nip 8~, Figure 4, and shown in more detail in Figures 9 and 10, is provided on the input side : 15 of the wire measuring and feed apparatus 41 and comprises an upper pulley assembly 86 movable against wires located ; in two lower pulley assemblies 87. The upper pulley .
assembly 86 comprises a series of lndividual pulleys 88 operated by respective triple ackion piston cylinder devices 89 located in a cylinder block assembly 63 in staggered relation. Control circui.try ~not sho~n) is provided to operate the piston and cylinder devices in three modes: to wlthdraw the upper pulley asse~bly 86 from the lower pulley assembly 87 to permit initial location of wires in the pulley assembly; to bias the upper pulley assembly 86 towards the lower pulley assemblies 87 to ; provide a l~w pressure on the wires during wire measuring, , :, .
~` 10~3 ~ 9~Z 4695 preventing overrun otherwise caused by inertia of supply reels; and, to provide a high pressure to lock the wires during operation of the output nip 81 during the wire feed.
The apparatus described enables substantially equal, predetermined, lengths of wires of different diameters to be fed simultaneously to the operating stations. Any xequirement for pulleys of different radii for wires of different diameter is avoided and as any small difference in wire ]engths initially drawn from the pulleys will be accommodated by differential slip between the individual output nips, the nips can be mounted on a common drive shaft driven at a single speed. As the output nips are isolated from the wire storage reels during the wire feed the nips do not have to overcome the inertia of the storaye reels avoiding slip and over-run and consequential errors in lengths of wires fed. The nips are subject to less ~ tension during the wire feed operation... The individual ; .!.1.)" rofo.f~o~
free ~Y~hk~r of the pulleys facilitates free movement of the individual wires during the wire measuring and feeding operations. The relative positions of wires of different diameters can be altered on the pulleys without alteration to any part of the apparatus which can, therefore, be used to make different wire harnesses.
