CIRCULAR-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 395,764, dated January 8, 1889.

Application filed April l0, 1886.

To all wiz/0m it may concern.'

Be it known that I, EUGENE VERMILYEA, a citizen ot' ythe AUnited States of America, residing at lVatcrford, in the county ot' Saratoga and State ot New York, have invented new and nse't'ul Improvements in Circular- Knitting Machines, ot' which the tollowing is a specification.

My invention relates to that class ot circular-knitting machines which are adapted to use latch-needles that are operated by jacks, and in which machines the web as produced is taken from the needles downwardly through the machinecylinder, the object and purpose of my invcn tion and improvement being to deliver.I the web upwardly to the take-up mechanism, so that it will be above the machine as produced and in a better position to be seen.

Accompanying' this specification to form a part ot.' it there are tive plates of drawings containing ten tigures, illustrating my invention, with the same designation ot' parts by letter-reference used in all of them.

Of these illustrations Figure l is a perspective ot' a circular-lniittil1g machine with my invention applied thereto, said machine being of the kind in which latch-needles are used. Fig. 2 is a vertical section taken on the line .fc m ot' Fig. l. Fig. il a cross-section ot' the frietionrolls of the take-np mechanism and the cloth-roll. Fig. -L is a top view of a deflecting-ring and the brackets by which it is connected with one ot' the stationary rings of the knitting-machine. This illustration also shows the position ot' the pressing-wheels that are by means of a stud and brackets connected with said ring. Fig. 5 is a vertical section ot one ot' thc ring-brackets and ring where connected with said parts, (shown as taken on theline r2 icot' Fig. 4.) Eig. G is an enlarged representation oi' one set ot thc cams which operate the needle-jacks, showing also the adjacent parts ot' the upper and lower stationary rings of the knitti 11g-machine on which the cams are placed, and also showing some of the jacks and needles. Fig. 7 is a side elevation of the take-up mechanism and the frame which supports it, with a part of the latter and the vertical shaft which operates Serial No. 198,425. (N0 model.)

it shown as broken out. Fig. S shows a section of one otl the small pressing-wheels. Fig. 9 shows an enlarged front view of a part of the needles, one of the large pressing-wheels, and one of the small pressing-wheels, one of the yarn-guides, and the outside of one of the cam-standards. Fig. lO shows a section taken through the ring under which the fabric passes to move up to the take-up mechanism, an edge view of one of the largerpressingwheels, and also an edge View of one of the yarn-guides and one of the needles, and a section of part ot one of the cylinders.

The several parts of the mechanism thus illustrated are designated by letter-reference, and the function of the parts is described as follows:

The letter C indicates the machine-cylinder, adapted to be rotated by power applied to the wheel lV by any of the well-known means e'mployed to operate knitting-cylinders of the hind shown.

'lhe letter S designates a sleeve, that is centrally and downwardly projected from the cylinder-bottom t to pass through the machine-table T', to rest with its bearing end on the plate p of the shelt' F, the latter being downwardly projected t'rom the under side ot' this table T.

The letter d designffites astrid, on which the sleeve S and cylinder C connectedly rotate.

The letter ni" designates a nut on the sleeve S, arranged to rest with its under tace on the table T. This nut or ring serves as a support to the cylinder and to steady the sleeve S, to which it is secured by a set-screw, substantially as shown.

NV designates a gear-wheel arranged below the table, with the sleeve S projected through and secured in its hub 7L. The sleeve S is castor formed on a cross-piece, 7, arranged across the bottom ot the cylinder C. On the shattt is a gear-wheel, et, which meshes with a geaiswheel, 5, journaled on a bearing fixed in the table, substantially as shown, and the latter in turn meshes with the wheel S, which rotates the cylinder. Power is applied through the band-pulley ll on shaft S and gears p6 and in,

The letter Ndesignates the latch-needles,

IOD

which are arranged in the outer face of the cylinder C, so as to project upwardly and inwardly on an incline. Y

The letter R designates an upper stationary ring that is supported on posts on. This stationary ring contains cams K', that en gage with jacks J to raise the needles as the cylinder C rotates.

The letter R2 designates another stationary ring arranged below the upper ring that is supported on the table T by the posts m2, and which is also provided with cams K2, arranged to operate the jacks j?, to draw down the needles forced upwardly bythe cam K ol the upper stationary ring, R', as the cylinder is rotated. y, The letters S2 designates studs, that are projected upwardly from the top ofthe deliecting-ring H. These studs are provided with brackets b3 and b, oppositely projected from the two sides of the studs.

The letters I designate inessing-wheels, that are provided with offset-bearings in each of the brackets b3, and the periphery of each of these wheels is arranged to press down upon the web inside of the needles between the latter and the ring I-I, to hold down the web when the needles rise.

The letters d2 designate other and small pressing-wheels, having the same function as the larger pressing-wheels, I, each of which wheels d2 is provided with an oifset bearing in one of the brackets, b4, so as to turn thereon. The rim-face of these pressing-wheels I and d2 are milled to .enagage with the web while holding it down.

The letter Y designates a yarn-guide, and d10 its standard.

The cylinder thus arranged with latch-needies and rings provided with cams to operate jacks to raise and lower the needles together with lthe pressing -whcels, before described,

constitute no part of my invention consideredl separately and apart from my improved attachment to the machine containing them, and with which they may co-operate.

The letter II designates a ring, the function of which. is to downwardly and in sequen ce ulgiwardly deiicct the web comin g vtrom the needles. This ring ll is attached to the upper stationary ring, R', bythe brackets b2. These brackets are arranged to project upwardly and to extend inwardly with an overhang above-that is, vertically inside of the needles-and each of these brackets is provided with an opening, O, at its upper and inner ends :for the upward. passage through it of one of the series of studs d3, arranged on the upper surface of the ring Il. These studs are threaded at their upper ends for the reception of nuts 'n3 n4 to make the studs and the ring II, which they connect vertically adlatter in the usual manner, as in this kind ot circular-knitting machines, and is then,by my improvennent, made to pass under said ring Il, and thence upwardly to the take-up mechanism at A. This take-up mechanism (shown at Fig. 7) is constructed as follows:

The letter F designates a stationary frame, S a vertical shaft, receiving power from a beveled gear-wheel, fw, on its lower end, and which meshes into a beveled pinion, 190,011 the shaft which drives the lmitting-maehine cylinder.

The letter g designates a gear-wheel on the upper end of the said shaft S, the latter gearwheel meshing into Yanother gear-wheel, gT, and the latter into a gear-wheel, g8, on the vertical shaft, which moves the take-up frame proper, and this geared connection, by which it is operated, is arranged to give it the same speed as the inachille-cylinder. The pintle p7, with which the gear-wheel g8 turns, passes down through so as to turn in a stationary cam-plate, C, that is pendent from the other side of the frame F6.

The letter r designates a rod or shaft, having bearings b in the top of the frame]ET of the take-up mechanism, and one end of this rod has a camroller, u, which serves to turn the rod in connection with the cam C, and the other end of this rod is provided with a crank, 7;which operates a pitman, p8, and a pawl, P6, to turn a ratchet, if, on the friction roller R7, which is provided with a gear, l, meshing with a gear, 2, on the other frictionroller, RS. The cloth-roll R9 is made to have its j ournaled ends turn in the usual vertical slots made on each of the inner and opposite sides of the frame f, so that as the web is -rollcd thereon and its diameter increases the journal ends of the roller Rf will risein said slotted bearings with the fabric or web on the lower side thereof rest-ing upon the sanded surface of the roller R7. The web in passing between and over the rollers R8 and R7, the surfaces of which are sanded, is caused to make a stron g frictional engagement therewith, by which it is moved upwardly, and by the frictional engagement between the web and the rollers R9, and the rolled-up web and said roller actuated to turn.

The take-up mechanism thus shown is of the usual and ordinary kind, and any other well-known form of take-up mechanism may be used that will roll up theweb in like manner.

Then the web passes down through the cylinder, as is the usual method in operating circular-knitting machines having latch-nee dles, the web is not so easily examined when produced as it is when caused to pass upwardly to the take-up mechanism by the use of my improvement.

Having thus d escribed'my invention, what I claim, and desire to secure by Iietters Patent, 1s
