Improvements in Knitting Machines.

Abstract

20,127. Page, S. E., [Mayer, O. L.]. Sept. 15. Parallel knitting-machines.-Relates to machines for knitting gloves. Each needle bed is provided with two movable sections L. The wrist and hand are knitted on the whole of the needles, using one thread-carrier only. The movable sections with the loops still on the needles are then tilted on shafts Q by means of levers T<1>, T<2>, pivoted at T, and levers S pressed together by a spring and by a cam W moved by hand between the rollers V. The movable sections are then fed downwards step by step as the first and third fingers M, N are made on the remaining needles by means of two threadcarriers. When these are completed, they are turned down, Fig. 13, their needles are put out of action, and the movable sections are raised, and the second and fourth fingers are knitted on them, using two thread-carriers. The movable sections are fed downwards by racks and pinions operated from a shaft f, which is intermittently driven from the main shaft E by a cam c, pawl lever g, pawl, and ratchet s. When the cam is between the rollers V, the pawl is out of action, and the movable sections are at rest ; when the cam W is moved from between the rollers, the bell crank Y, rod a, and lever b move a notched sector w, and so allow the pawl to drop into action. The cam c also operates a pawl lever i, which drives a ratchetwheel l and a sprocket-wheel on which runs a pattern chain. Bits on the chain trip a latch, and allow a spring to move a rod, which shifts the clutch and stops the machine. The stop-rod can be moved by a hand-lever independently of the pattern chain. The thread-carriers J, K are carried along to feed the yarn to all the needles, or to the needles on the movable sections alone, or to the remaining needles alone, by means of fingers 33, 34, which engage on one side or other, as the case may be, of projections 49 on the carriers. The positions of the fingers 33, 34 and, consequently, the motion of the carriers, are controlled by pins 38, 39 engaging grooves 45, 46 in a cam-bar 40. This cam bar is rotated by hand when the first and third fingers are completed, bringing the other pair of grooves 59, 60 into action while the second and fourth fingers are knitted.
