manner` previously described. ,Asg heretofore Y stated, when the belt has been shifted to the 'slow pulley, the movement of the Warp I9 and ythe take-up beam I1 Will be very sloW,-and therefore, the operator can replace l the lled beam' 40 Il with an empty'r beam without changingA the vrspeed ofthe mechanism. If for any reason', it

should be desired to automatically stopy the mechanism when the beam reaches a predetermined size such as I9b, it Would-only bey necessary to 45 adjust the collar 86 in such a position `on the v square shaft 60 that a greater longitudinal movement of the shaft 60 and'belt'shifter 39 Will be permitted, to permit the belt 3 6 to shift from onto the nner puhey e5.

After the delivery roll I4 and associated takeup beam have been slowed down or stopped, and after a filled beam has been replaced by an empty beam, it is kthen desired to resume the top operating speed. In order to do this, it is necessary yto release the trapped air orA iluid under pressure Ain the compression compartment II2 tofpermit the piston I`I5 and-associated connecting rod IIT which is disposed at substantially right angles tothe port |09 previously described. When material is being wound upon the take-up beam, the

'ports |09 and I 20 occupy the position lshown in y f Figures i and 5; whereas when the mechanism iS 70 `Second pulley for driving said beam at a reduced resuming top` speed, fthe ports are shifted from the position shown in Figure 5 to the position shownin Figure 6. At this time, the fluid -supply fromv thepipe` 94 and tank 96 is cut'oi by the valve, but the vrfluid from the compression k'I5 vfor admitting compressed air from'saidisupply l I I2, the 1 operator can then.;manually."y operate the yAs. va means?r` forlubricating interior-.of :the 'cylinder-1I I4'and `fthe pistn'vl I5;
