Application filed December 8, 1890. Serial No. 373,859. (No model.)

.T all whom it may concern.-

Be it knownv that we, JOHN CHADDERTON and ALFRED HITci-IINs, bot-h citizens of the United States, and residents of Philadelphia,

Pennsylvania,have invented certain Improve- .principal object being to Construct a machine applicable to the twisting' ot' a form of chenille, although it may of course be employed for yarns or strands of any character.

In the accompanying drawings, Figure l is a side view ot a twisting-and winding machine constructed in accordance with our in- Fig. 2 is a plan view of the same. Fig. 3 is a transverse section on the line 1 2, Fig. 1. the direction of the arrow, Fig. l. Fig. 5 is a longitudinal sectional v-iew of one of the spooling mechanisms detached from the machine. Fig. 6 is a-perspective view of one of the twisting-spindles. Fig. 7 is an enlarged view of the head of one of the twisting-spindles. Figs. 8 and 9 are views of details, and Fig. lO is a view of a modification.

The machine, as shown in Fig. 1,is divided practically in two parts, the 'portion Acarrying the twisting mechanism and the portion A carrying the spooling mechanism, but both portions are drivenfrom the common drivingshaft C.

XVe will tirst describe the twisting mechanism. The machine shown in the drawings is designed to twist twenty-four ends of yarn,

although more or less than this number may be twistedA by multiplying or decreasing the number of twisters and spoolers. Mounted on the frame A are a series of hollow twisting-spindles B. (Shown in detail in Figs. 6 and 7.) These spindles are adapted to bearings a a on the frame, and each spindle is provided with a gear-wheel b, which engages with intermediate gear-wheels b', as shown` by dotted lines in Fig. 3, so that all the gears of the spindles are in train. Motion is imparted to the train by a pinion c', mounted on the shaft c, which is driven from the main shaft C bya belt c2, passing around a wheel c3 on the main shaft and around awheel c4on the shaft c. Q As the twisting-spindles are all of the same construction, a detailed descrip- Fig. et is an end elevation looking in' ing its opposite ends secured in the `head B is a wiredZ, the coils of which, however, are of such size as to permit the free rotation of the roller d. In the outer end of the head B is an eye d3, through whichth'e twistedyarn is delivered to the winding-frames. The yarn enters at the mouth b2, passing through the spindle, is coiled once around the roller cl in the spaces between the coils of the wire d2, and from thence passes out through the eye d3, so that as the spindle is revolved the yarn is twisted.

Mounted in the standards A3 of the frame A are a series of sleeves D. to each of which is secured a pulley D', rotated by a belt passing over the pulley and over a drum E, each spindle heilig driven from said drum by an independent belt, and the wheels or pulleys on the spindles are so staggered that their belts will clear each other, as will be understood on reference to the accompanying drawings.

Passing through the sleeve D and rotating therewith is a spindle D2, having a central passage for the yarn delivered from the twisters and carrying at one end a flier e, constructed in any suitable manner, the radial Passingl around this roller in a helical form and hav-Y arm of'theiiier in the present instance having a passage e2, through which the yarn passes and is delivered to an eye c3 at the end of the flier. The outer end of the spindle is provided with a grooved collar f, rotating freely in a bearing f on one of the transverse bars of a reciprocated frame F, so that as the flier is rotated with the sleeve D it may be moved to and fro by the frame F to effect an even wind on the spool or bobbin. This frame F comprises two transverse bars f2f2, secured together by bolts g and sliding on guide-bars g on the frame-work.

Mounted on the frame of the machine is a transverse shaft G, carryinga pulley G', over which passes a belt G2 from asmall pulley on the main driving-shaft C, and on said shaft G is a belt-pulley g2, over which passes abelt IOO g8 to a belt-wheel G4 on a transverse shaft G. On the shaft G is a worm h, gearing with a worm-wheel h on a vertical shaft H, adapted to bearings on the frame A3. Secured to this shaft H is a cam h2, of the character shown in Fig. 8, which acts on a pin h3 of the bar h4, connected to a lever f3 on the rock-shaft H', said rock-shaft being mounted vertically in bearings projecting from the frame A' and provided with a series of arms h5, connected to the series of frames F.

To provide for the return of the frames after being moved in one direction by the cam h2, I place springs g2 on the guide-bars g between the fixed frame-of the machine and the frames F, or, if desired, the cam h2 may be made in the form of a grooved cam, so as to move the fram es positively in both directions.

Thus it will be seen that as the shaft H revolves the cam h2 acts to vibrate the rockshaft H moving the eye e3 of the flier over the face of the spool J, on which is wound the chenille or other yarn.

On the section A4 of the frame A are mounted small shafts I, carrying spools J, on which the yarn is wound by the liier. On each shaft is a belt-wheel t', driven by a belt t" from a drum or pulley 1 on a transverse shaft I2, this driving mechanism being similar to that employed for rotating the sleeves D, as already described. The spool YJ is slipped over an extension t2 of this shaft I, and is coupled to said shaft by a pin i3, adapted to a camgroove t4 in the plate i5 on the end of the spool, as clearly shown in Figs. 5 and 9, so that. as the shaft I revolves it will carry the spool on this shaft at the same speed; but to remove the spool from this shaft all that is necessary is to turn the spool in the opposite direction, the spool freeing itself from the pin by its cam-slot. As the diameter of the spool varies with the amount of yarn wound upon it, the speed of rotation of such spool is gradually lessened as the winding proceeds, a description of the mechanism for effecting such gradual change being as follows:

Referring to Figs. l and 4, K is a shaft having a belt-wheel 7c, around which passes a beltvk from a belt-pulley k2 on the drivingshaft C. On the shaft K is a cone-pulley L, the belt Z from which passes up and over a cone-pulley L', tapered in a direction opposite to that of the cone-pulley L, as clearly shown in Fig. 4. On the shaft L2 of the conepulley L is a belt-pulley Z, around which passes a belt Z2 to a belt-Wheel l3 on the shaft I2. The belt Z on the two cone-drumsis moved along gradually by a shifter M, one end of which engages the belt Z, the other end engaging a screw M on the shaft M2. Mounted on the end of this shaft is a ratchet-wheel m, and engaging with this ratchet are springpawls fn, pivoted to a reciprocating bar N, guided at one end by the shaft M2 and connected at its other end to an arm n on the rock-shaft H', so that as the rock-shaft vibrates it will reciprocate the bar N, the pawls of which engaging with the ratchet will turn the screw-shaft and feed the belt along the .cone-drums, gradually increasing or diminishing the speed of the spools, as may be desired. The shaft E is driven from a beltwheel p by a belt p', which passes around a belt-pulley 192 on the shaft E', so that the lspindles D2 are driven at a regular speed.
