from a conveyor chain 26 each carrier includes a plate 27 which is formed with a slot 28 in which is pivotally mounted a pair of part gripping levers 29 and 30 on an axle pin 31 first ends 32 and 33 of the levers are biased apart by an interposed spring 34 seated within opposed blind holes 35 and 36 formed in the respective levers in use an attending operator pushes a pair of parts down into the nests to pivot the levers 29 and 30 against the action of the interposed spring 34 which reacts to urge the levers to engage and hold the parts in the nests the entries to the nests and the lever ends are beveled or rounded to facilitate the entry of the parts into the nests as disclosed in fig2 the conveyor chain 26 is advanced by a sprocket 37 driven by a controlled speed motor 38 the conveyor chain passes over idler sprockets 39 and 40 and over the drive sprocket 37 to turn the carriers upside down whereupon the now downwardly extending terminals 17 18 and 19 are moved through a flux applying station 42 where a rotating brush 43 applies flux from a pool 44 to the wire wraps on the terminals next the conveyor chain 26 advances the parts from the fluxing station to a solder applying apparatus 45 of the type shown in fig6 and 8 where the insulation on the wire wraps is melted and removed and then solder is deposited on the wire wraps finally the soldered devices are conveyed to an unload station 46 whereat the devices are automatically dropped from the fixtures 24 the soldering apparatus as shown in fig6 and 8 includes a well 47 into which.
