To'll whom it may concern:

Beit known that I, HERBERT B. TAYLOR, or Philadelphia, in the county ot Philadelphia and State of Pennsylvania., have invented. certain new and useful I iiiprovenients in Circular-Knitting Machines, whereof the following is a specification, reference being had to the accompanying drawings.

My improvements have for their object, to obtain an increased production from a cir! cular knitting machine by increasing the relative speed of rotation of the operative lparts.

In ordinary circular knitting machines, as heretofore constructed, it' has been supposed that the speed at which the machine may be operated is chiefly dependent upon overcoming the friction between the cam cylinder and the needle cylinder'. It has accordinglybeen customary to rotate but one o't these elements and it has been deemed iniinaterial, which one is lrotated, so far as the quest-ion of speed is concerned.

In certain types ot' knitting machines` thc needle cylinder is maintained in fixed position, while tlie cain cylinder is rotated around'i't'; In other types of machines, the cani cylinder is held stationary, while the needle. cylinder is caused to rotate relatively thereto.

I have discovered that' apart from the rictonal resistance between the two cylin ders, I there are additional factors which ...limit'ithe speed of these machines. Among "ftliese rfactors are the friction occasionediby the motion off' the gears and their driving members, and the centrifugal ell'ect upon the yarn as it passes from the bobbins to the guide, whereby increased tension upon the yarn is created, In View of these factors this way, I have been able to greatly increase.

^ y the'output per day of the machine.

I have illustrated and will describe my invention as embodied in a rib-knitting ma- I chine -orfribsframe of ordinary construction; but lit isto be understood that my invention isnot thus limitedito this type of inachinebutapplies to any ordinary circular knitting machine producing a contim nous tubular web. I-

In the drawing. 1. is the bed plate, of a circular ribber, supported upon ysuitable standards A2. Within a suitable recess in said bed plate 1, is seated the annulus 3, which is provided along its lower outer edge with a rack 4, constituting it a gear .ring meshing with a beveled pinion 5, arranged to rotate with the main driving shaft 6, of the machine. rI`he cam cylinder 7, which integral with saidl annulus 3, carries the knitting cains 8, on its interior surface, and also carries the yoke 9, provided with a centrally depending stein 1 0, upon which is secured the dial cani plate 1l, having the dial cams 12, arranged to operatev the dial needles.

The needle cylinder 20', is rotatably supported yin 'proper relation to the'bed plate l, by the uprights 21, which stand upoiithe plate 22, supported tor rotation upon the base of the machine. `Tliese uprights carry the rack or bevel gear 23, which meshes with the bevel pinion 24, arranged torotate with the main driving shaft G.` Journaled iii the uprights 2l, and near their `lower end,\are' the takeup rollers 26, driven Vinthe usual way.

The dial 29, is free to rotateA upon than,A i

stein 10, beneath the dial' cam plate 11, but -l is held inl fixed relatioiitothe needle cylinder by the engagement of its lug 30, with a.

correspondinglug 3l, in thefneedle cylinwai' be tively driven iii one direction, while the p .cani cylinder 7, and dialcain plate l1, are' sie positively `drivcnin the opposite direction. I thus secure a relatively rapid-inotioinas' l `between the needle cams and the needles-- more rapid tliain'l'ias 4ever been pi-aoticalin any of the standardytypes otmachines, in

which one of the knitting members above mentioned is stationary, whilelhe'otl'ier i'olates; and inthis `way Iam able' to secure a. largely increased product from. the machine.

., Having thus described my invention, I'v

claim l. In a. circular' knitting 'niacliinin the con1' bination of a rotary cani cylinder, a rotary;

needle cylinder, and means for positivelyV rotatingl both olf said cylinders simultaneously, in opposite directions, lsubstantially as set forth. ,l

2. In a circular iiltlnntting machine, the

2 eoifeee l ,i l `l. l Y ,a i combination with the needle beds, vthe car. cylinder. gearing 'meshing on its opposite beds, and suitable 'supporting parts thefesides with both of said racks, and means to i rotate said geari1ig,\vhe1eby the needle cylinder and dial are rotated togetheiI in one direction and the cain cylinder and dial can plate are simultaneously rotated together in the opposite direction.

5. In a circular knitting machine, the conihination of a yrotary cam cylinder and a for; of means to rotate the needle bedrl in one direction and means Simultaneously 1.'.7

r rotate the cam beds in the other direction,

l whereby the production of the machine '119 "51, increased.

3. ln a circular rib-knitting machine.l the,

combination with the needle cylinder, the

10 dia-l, the cani cylinder, the dial cam-plate rotary needle cylinder; oppositely disposed 15 the dial cam-plate in the opposite direction.

and means for supporting the parts; ot 'means for rotating the needle cylinder and the dial in one direction and means for simultaneously rotating the cani cylinder and rear rings connected to said cylinders; and ear wheels onaconnnon sha-ft meshing n said gearrings whereby said cylinders, may be driven at dierent rates of speed.

in testimony whereof. I have hereunto 4, In a circular rib-frame. the combinasigned lny name, at Philadelphia in the tion with suitable supporting parts, of the State ot Pennsylvania. this 17th day ofMay needle cylinder, an annular rack connected 3 1906. to the needle cylinder, the dial, connections between the dial and the needle cylinder, the cam'cylinder, the dial cam-plate, connect-ions between the cam cylinder and the dial carnplate, an annular. rack connected to the cam HERBERT B.
