  • Each lug I 3 has anupwardly pointing-nose l5, Figure 3 4 the purpose of which will hereinafter become apparent.
  • a bobbin carrying member shown as a movable platform support I6 of channel section extends between the two uprights 4 provided for each bobbin cradle 3.
  • the support It has its web cut out at its ends so that it embraces the flanges of the uprights 4 and is therefore guided in the longitudinal direction of the machine by the uprights t and is therefore constrained, when raised or lowered, to rise or fall vertically in exact register with the axes of the bearings provided on the cradle 3 for the bobbin shaft.
  • the support Hi can be placed in position and removed readily without fastening or unfastening any part.
  • a horizontal pivot pin H is mounted in the flanges of the support It at each end thereof and a hook I8 is mounted on the pin i? at the outer side of each flange of the support it so as to be oscillatable.
  • Each two hooks t8 on the same pin are tied together by rigid ties is so that they oscillate together.
  • a bent pivoted connecting rod extends externally along one side of the support I6 and has one end connected at iii to one of the coupled pair of hooks is above the pivot pin I1 thereof and the other end connected at 22 to one of the other coupled pair of hooks 48 below the pivot pin I!
  • the hooks 13 are adapted to be engaged from below by the hereinbefore mentioned lugs l3 when in an outer position and to be clear of the lugs l3 when in the inner position.
  • Each support it has mounted on it a bobbin platform 23 the base of which lies in the channel of the support it and the supporting surfaces of which are sufficiently elevated above the support it to enable the bobbin 2% resting on the said surfaces to be raised into position in the cradle 3 from below without the fouling of the support it with the rotary member 25 of the stranding machine.
  • a bobbin can be hoisted into position in any single one of the cradles 3, or bobbins can be simultaneously hoisted into any selection of the cradles 3, or bobbins can be hoisted simultaneously into position in all of the cradles 3.
  • Unloading of empty bobbins can likewise be effected singly or simultaneously in any series or all together, the lowering of the support It or supports 16 after the corresponding platform or platforms 23 have been raised to support it, being effected by allowing the two bars 2 simultaneously to slide back into the initial position under the Weight of the chains ll, slides I2, and any platform or platforms 23 support or supports l6 and empty bobbin or bobbins thereon.
  • each shaft 25 has a sprocket wheel 3t fixed to it and meshing with two pivotal link chains 35 one end of each of which is connected to the correct end of one of the bars 2.
  • the other end of each chain 35 is anchored at 36 to the corresponding rail i so that it forms a loop which carries a jockey sprocket wheel 3? which is weighted by means of a rotatable stirrup 33 carrying a weight 39.
  • a releasable locking pawl and ratchet (not shown) associated with the shaft 30 or other suitable locking means are provided to prevent unwanted rotation of the shaft in the lowering direction.
  • Suitable starting and reversing means and automatic stop means which are already well-known in connection with electric motors are provided to control th motor and prevent overrunning of the shafts 25.
