IMPROVEMENT IN SPINNING-MACHINES.

Specification forming part of Letters Patent No. 145,322, dated Decembe r 9, 1875i; application iied July 11, 1873.

To all whom fit may concern:

. Be it known that we, CHAUNcEYWILLrAMs, SAMUEL M. VILLIAMS, and HENRY M. WIL- LIAMS, of Coldwater, in the county ofBranch and State of Michi gan, have invented a new and useful 'Improvement in a Spinning- Machine; and we do declare that the following is a true and accurate description thereof, reference be-r ing had to the accompanying drawings, and to the letters of reference marked thereon, and heilig a part of this specification, in which- Figure l, Sheet 1,. is a perspective view. Fig. 2, Sheet 2, is an` elevation of the lefthand end of Fig. l. Fig. 3, Sheet 3, is a plan of the top. Fig. 4, Sheet 4, is a crosssectionA on the line :v x in Fig. 1. Fig. 5, Sheet 5, is an enlc rged longitudinal section of a twisting-tube taken through the line y y in Fig. 3. Fig. 6 is across-section on z z in Fig. 5. Fig. 7 is an end view of the twisting-nut on the end of the tube. Fig. Sis an enlarged vertical section of aspinning-ring and bobbin on its spindle. Fig. 9 is a similar section of the bobbin.v Fig. 10 is a view of the slotted vquadrant-arm which carries the change-wheel in the feed-train. l

The nature of this invention relates to an improvement in machines in which woolen rovings may be spun into yarn and wound upon bobbins continuousl f; and it consists in the peculiar construction and arrangement of the mechanism for raising and lowering the platform which carries the bobbin-spindles also, in the peculiar construction of said twisting-tubes, provided with changeable crossslotted nuts, antL in other arrangements. of devices, as hereinafter described the arrangement of the whole being such that the tubes twist the rovings suiiiciently to give them the required strength to resist the tension put upon them While being subsequently spun, the twist so given being taken out and reversed by the spinning-rings,which wind them as fast as spun upon the bobbins.

In the drawings, Al represents the frame of our spinner, in' the lower right-hand en'd of which a driving-shaft, B, is journaled, which shaft, besides the usual fast and loose pulleys a af, is provided with a large cone-pulley, B1, from which motion is given to a drum, C, journaled across the back part of the frame, by a belt, B2, passing around a cone, Cl, on the end of said drum. D is a spii'ining-ring bearin g, preferably of metal, made in two parts, D D, resting horizontally upon brackets projecting from the front of the frame, to which the inner part, D, is permanentlyT secured, the front half being secured to the part D by bolts b passing' through both, with nuts 011 their front ends, by which the twoparts may be brought together with any desired degree of compression. These parts are internally channeled, and in them are drilled vertical bearings, at regular distances, for the hollow spinning-rings E, Figs. 4 and 8, havingl jour* nals turned down on their ends, which rotate in the bearings halved in the upper and lower sides of the parts D D. The part D has an opening behind each bearing through which a cord, C2, passes with a quarter-turn around each ring, which is grooved around its middle to receive the said cord from the drum C, and each ring is provided with an eye c, at its top end, through which the yarn passes. Below the ring-bearing brackets, another pair of brackets projects from the lower part of the frame, which support the guides d d, whose tops are secured to the brackets above, and upon each slides a cross-head, f, Fig. 2, to which is secured a two-part spindle-bearing, F F', in which the lower ends of the bobbinspindles G are journaled, thek two yparts F F being secured together by three transverse bolts, c, whose nuts may be screwed up to im pede the free rotation of the spindles, whose bearings may be of wood or metal, as preferred. I are the bobbins, each secured upon thc taperingspindle, and playing freely through the opening 1n the spinning-ring E above, as the bearing F F is raised or lowered, which is effected in the following manner: At the side of each cross-head fis pivoted the lo wer end of a connecting-rod, I, whose upper end is pivoted in a slot, g, of a lever, I, by a pin,"fi, the said lever being pivoted back of the slot to the sido of one of the front posts of the frame.

To the rear end of each lever is pivoted a connecting-rod, I2, whose lower end is strapped to an eccentric, H, at each end of a shaft, J, journaled in a bracket projecting up from one of the lower girts of the frame. This shaft J is slowly rotated by its bevel-pinion K meshing with a bevel-gear, K1, mounted on a vshort vertical shaft, K2, journaled in suitable bearings, and carrying a horizontal wormgear, K3, rotated by a worm, K4, on the inner end of the driving-shaft B, whose rotation thus causes the rise and fall ofthe spindle-bearings. When the bobbins are empty, and to be wound, their bases are flush with the tops of the rings, through which they fall their own length, and rise again at each revolution of the eccentrics, which is sufficient to ll them with one layer of yarn. This would, however, wind them with yarn into the shape of cylinders; and, to give them the shape required, it is necessary that the bobbins should move slowly at mid-height, and faster at top and bottom, and to this end we employ the following mechanism Near the left-hand end of the shaft J we key a pinion, L, which, through a train of spur-gears,

L1 L2 L3, communicates aslow motion to a shaft,

M, journaled racross the lower girts of the frame, carrying at each end a wiper-cam, N, upon which rests the horizontal arm of a bellerank, 0, pivoted to the side of a front post in the frame. The upper part of veach bell crank is a curve or segment, and has a slot, g', into which one end of the pin t' of the connecting-rod I projects. The wipers N are so timed. with relation to the throw of the eccentrics that the pin 11 is thrown forward in thev slots g to give it a greater radius, and consequently a more rapid vertical movement to the spmdle-bearin g, while approaching or receding from the ends of the bobbins to the middle,T

andaslower movement from the ends toward the middle of the bobbins, by reducing the radius of said pin in the slot g, thereby causing more yarn to be wound upon the middle, and less at the ends of the bobbins.

The feeding and drawing rolls are at the top of the machine, and to operate them we employ the following mechanism: 0n the shaft B there is a pulley, Q, one edge of which is seen in FiO. l, from which a crossed belt, Q, is carried around a pulley, R, mounted on a shaft, R1, journaled in and projecting inwardly from the right top girt of the frame, and carrying a pinion, R2, which meshes with and gives motion to a spur-gear, R3, whose shaft is journaled in a bracket on top of said girt, with a bevel-pinion, R4, and a spur-pinthereof, whereby any desired pressure may be exerted by the elastic rollers Z upon -the upper rollshaft on the metallic rollers l1 mounted on the lower roll-shaft, the yarn passing between and being drawn forward by the said rollers.y The pinion R5 meshes with a change-pinion, U, mounted on a stud projecting from the slotted quadrant Y, Fig. 10,'bolted to the side of the top girt, and meshes with a changewheel, U,'mounted on a stud at the lower end of said quadrant, which in turn meshes with the pinion U2 on the end of the lower feed-roll shaft YV journaled in the standards J"- boxes sliding in the same standards, and earries a series of elastic rollers, l2, while the lower roll-shaft carries a series of inelastic rollers, Z3, upon which the rollers Z2 may be caused to press by screwing down the capbearings of the upper roll through the setscrews k in the standards j. Near the end of the lower roll-shaft W is a pinion,U-3, which meshes with the gear U4, which vdrives a spurwheel, U5, at the end of a shaft, X, which carries the roving-drum X1 at the back of the the machine, thence each through an eye, c, on

the spinning-ring E, to the bobbin. J ust before passing between the drawing-rolls the roving passesV through a twisting-tube, Y,

journaled in a pillar, Y2, on the frame-top,

and to which an axial rotation is imparted by a quarter-turn endless cord, n, from a-drum, Z, journaled in brackets below, which drum is driven by a belt, Z2, passing around a pulley, Z2, on its end from a pulley, C3, on the end of the drum C. The twisting-tubes may be either cylindrically bored and tapered at the rear end ofthe bore, as shown in Fig. 5, or be tapered from end to end, as preferred. In the end of each is screwed a nut, Y1, having a cruciform slot through which the yarn must pass 5 these nuts may have different sizes of slots for twisting coarse and -iine rovings. The feed-rolls have a slower movement than the drawing-rolls, while the spinning-rings have a higher speed than either. The relative speeds of the latter and of the twistingtubes are unchangeable, but, by means of the quadrant Y and changing the pinions U and U1, the speed of the feed-rolls may be changed so as to put a greater or lesser tension onthe rovings the less speed given the feed-rolls the greater the tension will be, and vice versa. The speed of the machine, as a whole, may be varied by shifting the driving-belt B2 on the cone-pulleys. The ends of the rovings being passed between the feed-rolls, they are thence passed through the twistingtubes, thence through the eyes c of the spinning-rings E, and tied to the bobbin-bases. The machine W is the top feed roll shaft, journaled in Y being in motion, the tube-s twist the rovings suiiiciently to enable them to stand the tension put on them by the drawing-rolls, their diameters being correspondinglyreduced. The twist put in the rovin gs is taken out by the spinningrin gs, which rotate in the opposite directions, Winding the yarn `spun upon the bobbins, the spindles being slowly rotated withthe vbobbins by being cramped in their bearings to such 'an' extent that about two-thirds of the tension is put in by the drawing-rolls, while the remainder of the tension is put in by the spindle -bearings Each rotation of a' spinnin g-ring puts a twist in the yarn and lays a coil around the bobbin, while each time the eccentrics rotate to raise and lower the bobbins 'a layeris wound upon them. One rota. `tion of the wiper-cams is vsufficient to ll the bobbins and give them the necessary swell at the middle. When a spool of rovings is run off, another one, filled and lying in the sockets at the top of the spool-bracket, replaces the empty one. The ends of the royings, being connected with' those passing through the feed-rolls, are continuous. When a bobbin is wound full the motion of its spinning-ring E is arrested by a brake until it can be removed and replaced in the following manner: o is a brake-block, sliding in an opening through the rear side of the bearing D at the back of each ring E. p is a shaft, secured in brackets projecting from the frame below and behind the bearing D, and on this shaft are hung the bellcrank treadles q, each of which maybe depressed by the foot, when its top end will force thek brake block inward against the ring E to arrest its motion.
