Specification forming part of Letters Patent No. 35,966, dated July 22, 1862.
To all 'whom'it may concern: I .Be it known that I, GEORGE CAMPBELL, of Waterford, in the county otSaratoga and State of New York, have invented a new and useful linprovenieutin the Take-Up of Circular-Knit ting Machines, and I do hereby declare that the following is a full, clear, and exact description of thesame'," reference being held to the accompanying drawings, forming part of this specificatiomin which- Figure 1' is a side view of the take-up. Fig. Fig. 3 is a vertical section of the principal parts of the same. Similar letters of reference indicate corresponding parts in the sevcralfigurc's;
This invention relatestothetakeupof those cylindeuknitiing machines in which the needie-plate or needle-ring and the work have a rotary motion; and it consists in a certain means of producing and controlling themovements of a pair of takeup rolls arranged'ahove the knitting-machine with their axes perpendicular to the axis of rotation ofthe needle plate or plates. v r a v To enable others skilled in the art to make and use my invention, 1 will proceed to de scribe its construction and operation.
A is a quadrangular frame-suspended in an upright position above ,the knittingniachine from a crane-like standard, B, by means of a fixed upright pin or stud, a, which is secured in the said standard with itsaxis in'line with theexis of-the needle 'ring or needlerplate.
The said pin or s't'ud only passes through the upper part of the said frame, and the frame'is free to have a rotary motionupon'the said pin corresponding with the rotary motionlof the needle-plate or needlering C.
'1) D are the take-up rolls, arranged horizontall'y in the lower part of thefrau'ie 'A' and geared together outside or one end of the saidframe by a pair of spur-gears, one of whic'lris indicated by the letter b in .Fig. 2; Outside of the opposite end of the frame the upper roll,-
D, whose bearings are-fixed inthe saidframe, has firmly secured to its spur-gear, '0, Fig.1.
which gears with a loose gear, d, attached to with anoth'erlcose spur-geanfl attached to the vided two pawls, s and i, the latter for giving it the necessary motion to produce the taking up of the work, and the former for preventing it fromturning hack and thereby causing the retention of the work after it has been-taken up. The pawl s is attached to the side of the frame Ahy the stud j and the pawl i to a 1e.-
-ver, E, which works upon a flllclllllil'plll, k,
attaching it to the frame A. The lever E is slotted at about the middle of its length, as
shown at Z, Fig. l,to allow it to work clear-ofthe stud j, and near its upper end it'hus an opening, m, for-the reception of the-end (ii a lever, F,- whieh is arranged to'work horizoh tally on the top of the frame A on afnlcrunipin, n, Fig. 2, which attaches it to the said frame. This lever F is kept by a spring, 15in contact with an eccentric, q, formed upon or secured tothe'pinu. The distance oif the movement of the levers F and -E is limited by the upper part of the lever E working in aslot, r, in a plate, G, which is secured on the top of the frame 1 The rotation'ol' the frame-Aupon the .pin 11, produced by and" corresponding with the. 1
,tarymotion of the needlering and the work,
causes the lever F to haven. regular vibrating motion imparted to it by the revolution around and in contact-withthe stationary eccentric g, and that lever imparts motion to the lever E in such manner that if the pawl i is not held up out of gear with the. ratchet wheel k the said pawl will produce a movement of the said ratchet-wheel, and so cause a quantity of the knitted fabric to be taken up by therollers l) D at every revolution oftheknitting-maehiue; but this pawl isheld up out of gear with the ratchetwheel by the tension of the goods, ex-
cept when the said tension becomes so slight as to require more goods to-be taken up. The
means through which the tension is made to act upon the pawl are as follows:
H are two fixed round bars forming the lbottoin of the frameA, hrranged side byside the frame A- by a stud,'e, and this gene dgears' helowthe lower take-up roll, D, and parallel with the takenp rolls. His'e. frame arranged to rock upon the ends of the bar t',jwhich are made to project through the ends of the frame A for the purpose. This frame carries on one side a roll, I, parallel with the take-up rolls, and on the opposite side it has an arm,J,
, which is connected by a spring, K,witha rigid arm, K, secured to the top of the frame, the said spring tending to pull up the arm J and depress the'roll Lw-hich is connected with the pawl i by means of a rod, L, in such-manner that when the said roll is raised the pawl is raised also, and vice versan The knitted goods, represented bya red line in Fig. 3, pass upward from the machine over the bar t, under the roll I, thence upward between the take-up rolls to a roll, M, on which it is to be wound as fast as taken up, the said roll L resting on the top takenp roll, D, de-
riving motion therefrom by the friction of their surfaces and of the interposed goods. The tension of the goods acts to raise theroller Iand lift the pawl 2' out of gear with the ratchet-wheel kin opposition to the action of the spring K,which tends to depress the roll and keep the pawl in gear, and hence while the goods have a certain degree of tension the action of the take-up rolls is suspended; but when the tension becomes less the rolls resume their action. Toprovidefor taking up with greater or less rapidity, for the purpose of making the work less or more clos'e,the rod L is made with a slot, 2:, at its connectionwith the roller I, the end of the said roller passing through the said slot, and a slotted coveringplate, 20, being fitted to the outside ofthe said rod and secured thereto by a screw, '10, for the purpose of closing (more orless) the upper part of the slot 12. WVhen much of the slot 0 is uncovered, the roll I is allowed to rise higher, 'without acting upon the rod L,to fit the pawl than when less is uncovered, and hence by adjusting the plate to higher up the rod the goods will be caused to be taken up'faster, as' the take-up rolls will continuein operation with a greater degree of tension on the goods, or by adjusting the plate 10 lower down the rod the opposite effect w'ill'be produced.
What I claim as my invention, and desire to secure by Letters Patent, is-- 1. The employment, for operating'the takeup roll or rolls 1) D, of a lever, F, attached to the rotating frame of the take-up and rotating with the take-up rolls and with the pawl i,
from'which they derive motion, substantially as herein specified.
