Intermittent motion is given to ‘the take-up 'rality of loopers III, these loopers being wVerti cally adjustable by ‘means of suitable set screws , IE3 and the sections of the ‘looper bar ‘I I0 being 40 secured to the looper shaft I93 'bymeans of a roll 59 by means of a free wheeling clutch ar rangement ?xed on the stub shaft 57. This com prises a member ‘I9 rotatably mounted on stub plurality of bolts'I I4. ‘It is to be noted that the front or pointed ,portion of ‘each looper ‘has a shoulder "H5 which is adapted ‘to engage the strand as the extreme pointed portion of the shaft 51 and having a lever arm ‘II ?xed thereto .1, ‘ looper passes ‘between the strand and the needle which projects forwardly of the machine and is slotted as at ‘I3 in which is adjustably mounted by means of a bolt M the lower end of a link ‘I5, the upper end of which has a bearing which en circles an eccentric ‘I6 ?xedly mounted on shaft , I6. This imparts up and down motion to the free end of lever .‘H and'thus oscillates the mem ber 19 back and forth on the stub shaft 51,. The periphery of member 10 has a plurality of tapering notches BE! therein in vwhich rollers I8I are mounted. Fixedly, mounted on stub shaft 51 is a cup-shaped member 83 whose periphery is adapted to encircle the member ‘I6. An annular member 84 is ?xed over the open end of the cup shaped member ‘83 to con?ne the member "II! ‘against endwise movement on the stub shaft 51 and to con?ne the rollers 8| in the notches 89. as it moves to lowered position, and thisshoulder prevents the loops from travelling further back on the looper as-shcwn'in ‘Figure $6. With theparts in'the position shown in Fig ure 5, as the needle starts its upward movement, the closed-channel ‘9B in cam wheel 95 oscillates arm 98, which oscillates the shaft 99 to move the looper point in between the yarn carriedby the needle and the needle itself, and immediately verging end of the notches 80 and will be wedged between the wall of the notches and the periph eral portion of the member 63 and will therefore above the ‘needle eye, and vthus prevents the yarn from being withdrawn from the fabriclon the up— ward travel of the needle. At the same time, after the looper has passed in between the ‘needle and the yarn to cause the yarn to impinge against its shoulder II the eccentric Mil causes down ward movementof arm IIM‘to also oscillate shaft "I03 ‘to the position shown in ‘Figure 6 to thus draw out the loops to a much greater length than would bet-he case were not this double oscillation . given to the shafts 99 and H33 respectively, The vertical posts iii] and II rest onfa ‘base member I529, which with frame members 'I'2I, I22, and I23, form a support for a shaft I24 on which a roll of the cloth 5% is adapted'to be supported. This cloth on its way to the upper ‘surface of the bed plate passes over a roller I25 impart a step by step rotation to the take-up roll rotatably mounted in’bearings I25 supported on ‘ It is‘thus seen that as the lever ‘III moves down wardly, the rollers 8| will roll back into'the larger portion of the notches 8i) and will have no tend , ency to move the cup-shaped member 83; whereas, upon upward movement of the free end of lever "I I, the rollers 8| will move into the narrow or con 59. This movement of the shaftB'I and the take ~up_roll 59 occurs‘while the needle is moving up ~warclly out- of the fabric and downwardly to. blocks I2? secured to the front surface of the front vertical posts I9.
