AUTOMATIC TAKE-UP FOR ROTARY KNITTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 463,788, dated November 24, 1891.

Application filed June 17, 1891.

To aZZ whom it may concern:

Be it known that we, \VALLAUE HOSE and HENRY CURTIN, of Little Falls, in the county of IIerkimer, in the State of New York, have invented new and useful Improvements in Automatic Take-Ups for Rotary Knitting-Machines, of which the following, taken in con nection with the accompanying drawings, is a full, clear, and exact description.

The purpose of this invention is automatically to take up and wind neatly and compactly upon a roller the fabric issuing from the needle-cylinder of a rotary knitting-machine and to effect the same at a continuous and uniform speed corresponding to the speed of knitting; and to that end the invention consists in the novel take-up mechanism hereinafter fully described, and set forth in the claims.

In the annexed drawings, Figure 1 is a side elevation of a knitting-machine embodying our invention, a portion of the frame being broken away to illustrate more important tal gear-wheel, which is attached to and drives the needle-cylinder. Fig. 4 is a horizontal transverse section on line y y, Fig. 1. Fig. 5 is an inverted plan view, partly broken away, of the lower end of the revoluble frame, showing the adjustable attachment of the pinions which transmit motion from the stationary gear to one of the take-up rollers. Fig. 6 is a top view of the aforesaid attachment of the pinions. Fig. 7 is an enlarged vertical transverse section of the main portions of the revoluble take-up-carrying frame, taken on line 2 .2, Fig. 8; and Fig. 8 is an enlarged vertical sectional view on line 0 0, Fig. 7.

Similar letters of reference indicate corresponding parts.

Serial No. 396,564. (No model.)

passes down through the tubular hubs of the needle-cylinder and of the wheel B, as indicated by dotted lines 1 1. In order automatically to take up this fabric issuing from the needle-cylinder at a uniform speed corresponding to that of the knitting, we employ the following mechanism.

To the under side of the gear-wheel B we rigidly secure the vertical frame 0, the lower end of which is sustained laterally by a horizontal spider F, rigidly secured to the lower portion of the frame F and having firmly and rigidly secured to it the spur-wheel I-I, upon the hub of whichthe base of the frame 0 v rides and is pivotally secured to it by a bolt n, passing vertically through the spider and the aforesaid superimposed parts, as best seen in Fig.2 of the drawings.

R denotes the take-up roller upon which the fabric is to-be wound, said roller extending horizontally across the frame and is sup ported to yield vertically, preferably byvmeans of prolonged spiral springs c seated in vertical tubes d d, secured to opposite sides of the frame, said tubes being slotted vertically at their upper ends for the reception of the trunnions of the roller B, said trunnions being mounted in journal-boxes e, which are mounted upon the upper ends of the spiral springs d. The vertical slots areextended through the upper ends of the tubes to allow the roller to be removed when desired.

In order to allow the aforesaid springs to be adjusted in their tension, we close the lower ends of the tubes d dand provide the bottoms of the tubes with screw-threaded eyes, in which are inserted set-screws e e, upon the inner ends of which rest the followers (1, on which the spiral springs are mounted, as shown in Fig. 7 of the drawings.

R represents an auxiliary take-up roller, which is arranged before the take-up roller proper R and parallel therewith and preferably fluted. Said auxiliary roller is j ournaled at opposite ends-in the frame 0, and has one end of its shaft projecting from the exterior of the frame 0, and has loosely mounted on it a worm-pinion f, and to the outer side of this pinion is fastened one of platesj of the friction-clutch. The other plate j of said clutch is mounted to move longitudinally on the shaft, and is connected to it by spline and groove, as shown at j in Fig. 7 of the drawings, and has secured to the side adjacent to the platej afriction-disk 7c, of leather or other suitable material. The free end of the shaft of the roller R is screw-threaded and provided with a set-nut m and jam-nut m, and between the nut m and clutch-plate j is interposed a spring-plate o, as clearly shown in Fig. 7 of the drawings. 2y turning the nut on so as to cause the spring 0 to press the clutch-plate j tightly against the other clutch-plate j, the worm-pinion f be comes fastened to the shaft of the roller. Said pinion receives rotary motion from the worm g on the upper end of a vertical shaft g, which is journaled in suitable bearings secured to the rotary frame (J.

To the base of the frame 0 is fixed a horizontal arm 0, which projects from the side of the aforesaid frame, and has pivoted in i s free end a short vertical shaft projecting from the top and bottom of the arm and having secured to opposite ends thereof two pinions i i. The lower pinion t' meshes with the spur wheel H and the upper pinion t" meshes with the pinion 72 secured to the lower end of the shaft g.

Inasmuch as coarse-knitted fabric is produced faster than finely-knitted fabric, it is necessary to adjust the gearing so as to conform the motion of the take-up mechanism to the speed of the knitting, and to accomplish this we employ on the arm G interchangeable pinions t' and L. of different diameters, and in order to allow the said pinions to mesh with the spur-gear H and pinion h we connect the arm 0' to the rotary frame 0, so as to be adjustable longitudinally, by providing the said arm with a longitudinal slot 1), through which pass the screws 19', which fasten said arm to the frame C, as shown in Fig. 5 of the drawings, and upon the said arm we mount adjustably in a similar manner the plate 7', in which is stepped at t the vertical shaft g, as shown in Fig. 6 of the drawings.

Over the auxiliary take-up roller R and parallel therewith is a companion auxiliary takeup roller R, also preferably fluted, and held yieldingly contiguous to the roller R by the journal-boxes b of the roller R, seated movably in guideways a, formed on opposite sides of the frame 0. In line wlth each of said guideways is a chamber a, separated from the guideway by a partition a, which is perforated at its center, as shown in Fig. 8 of the drawings. The journal-box b is provided with a stem Z), which projects through the perforation of the partition a" and longitudinally through the chamber a, and is screw-threaded on its free end, and to said end is connected an adjusting-nut c, and between the inner end of this nut and the partition ct is a spiral spring 0, surrounding the stem I) and exerting an outward pressure on the nut c, and thereby drawing the roller R toward the roller R.

In the operation of the machine the fabric passes between the two rollers R and R, and after the lower end of the fabric has been once wrapped around the roller R the top portion of the wound-up fabric is pressed against the fluted roller R by the action of the springs forcing the roller R upward. or toward the roller R. The*frame O, rotating synchronously with the needle-cylinder A and with the fabric issuing therefrom, maintains the take-up rollers R, R, and R" constantly in proper positions in relation to the needle-cylinder and the travel of the fabric from said cylinder. The roller R receives rotary motion from the spur-gear II by means of the vertical shaft g and its geared connections with the said spur-wheel and shaft of the roller R, as hereinbefore described. The pressure of the roller R upon the fabric passing between it and each of the othertwo rollers R and R imparts rotary motion to the latter rollers, and thereby passes the fabric to the take-u p roller R and winds it upon the same.

In the operation of first applying the fabric to the roller R the nuts m m are to be loosened to relieve the clutch member j from the pressure of the memberj',the pinion f being I then permitted to rotate freely on the shaft of the roller R, and the said roller can be turned by hand without turning the shaft g.

To facilitate the turning of said roller by hand, a hand-wheel t is attached to the opposite end of said roller, as shown in Fig. l of the drawings. After the fabric has been wound once around the roller R the nuts m m are to be tightened on the shaft of the roller R, so as to lock the pinion f on the shaft by the clutch j and j. The rollers R, R, and R are then turned with the motion of the needlecylinder, and the fabric is wound automatically on the roller R.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. In combination with the needle-cylinder, the frame G, rotating with said cylinder and provided with guideways a a, chambers a c, and perforated partitions a between them, the auxiliary take-up roller R, pivoted in said frame beneath said guideways, journal-boxes b, seated in the guideways, the roller R, jour' naled in said boxes, stems 1), extending from the boxes through the partitions a" and chambers a and screw-threaded on the free ends, adj usting-nuts c on said stems, and springs 0' between said nuts and partitions and yieldingly forcing the roller R toward the roller R, substantially as described and shown.
