Letters Patent No. 88,450, dated March 30, 1869.

IMPROVEMENT IN SPINNINGfM'ULE.

The Schedule referred to in these Letters Patent and making part of the same To all whom 'it may concern.-

Be it known that I, B. C. GOLDWELL, otWyomiug, in the county of Luzerne, and State of Pennsylvania, have invented a new and useful Improvement in Spinning-Machines; and I do hereby declare that the following is a full, clear, and exact description4 of the construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a top view;

Figure 2, a side elevation;

Figure 3, a back view of my machine, and

Figure 4, a detailed view. Y

The nature o f my invention consists in novel mechanism for operating the faller, wherebythe spinningmechanism is adapted to wind up the threads of the bohbins in a more perfect and regular manner than could be done heretofore, the object being to produce an elegantly-shaped bobbin, withthe threads uniformly wound.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In tig. 1, A represents the so-called faller, the same consisting of a wire ruiming nearly across the whole width of the spinning-machine, and being attached to the ends of a number of levers, one of which is seen at arwhich are fastened to a rod, B, parallel with A.

The rod B is operated by au angular lever, C, and a weight, D, on` an arm, d..

lhe motion of lever C is received from a main pulley, E, through the medium of parts hereinafter described.

This pulley E receives its motionfrom a belt from the cylinder of the spinning-machine, in a well-known manner, and it is supported by but not fastencdto a shaft, E, and has one or more V- shaped clutch-teeth, c, on one side, and a clutch-hub, c, on the'other side.

A clutch-head, E2, which, by means of a hub, c, and groove, c", forked lever H,. and a key, tf, can be moved away from or toward the pulley E, will, in the latter case, participate in the motion ofthe pulley, and trans fer it to the shaft fl, and from there, by means of an exchangeable pinion, E3, to an adjustable intermediate wheel, E, which imparts its motion to another toothed wheel, E5, on a shaft, EG.

I ironi this shaft, the motion is transferred by means of a bevelled gear, El, gearing into another bevel-gear, F, on a shaft, F, to which a screw, or worm, 1*", is fastened. v

A worm-wheel, F, is rotated by said worm F2, and, being fastened to a shaft, 1*, with a pinion, F, at its end, which gears into a rack, F, it imparts a very slow motion to the rack, so that the said rack will only travel its own length, or part of it, i-n the time nccessar f' to finish a complete set of-bobbins on the spinning-machine.

This rack is connected to another rack, FS, by means of a lever, or connecting-rod, F7, and a spring, F9,

The two racks mentioned are parallel, or nearly so, and the connecting-rod F7 is pivoted to one end of each of them, as seen plainly in g. 2.

The spring Fg is fastened to the upper end of an upf. right projection, f, on rack Fj, and to the lever F7.

Another upright proj ection, f supports a set-screw, or pin, f", in such manner that the head of said setscrew will prevent the spring F9 from drawing the lever F7 further onward than the operator may desire.

There are also two pins, f3 and f, fastened to an upright bearing, G, which supports a lever, G, having a bearing-tooth, g, and a weight on its end.

The pins regulate the movement of the lever FT;

andthe tooth g, on lever G, bears ona heart-shaped The shorter end of the angular lever G has a connecting-rod, G2, pivoted to it, which moves a cross-head, G3, between two horizontal slides.

A pinion, G4, is so pivoted to said cross-head that itl gears into the rack FS, and into another rack, G5, both of these racks being parallel to the guides of the crosshead above mentioned.

The rack GI", which is enabled, by two small crossheads `and horizontal guides, to move in a horizontal line, parallel with cross-l1ead G3, has a tooth, g', fastened to it, which fits into anotch on the lower part of a rod, G6pivoted to lever C, by which means rack G5 audi-od GE may be coupled or disengaged.

`The rod G is provided with a peculiarly-shaped wire, or rod, g2, which serves as a guide for G, when travelling, and enables a lever, H', to lift it when necessary.

Levler H is of angular shape, and receives motion through a connecting-plate, H3, and a rod, H2, having a bumper, h, at its forward end.

H2 transfers its motion, also, by an upright pin, h, toa compound lever, H4 H6 H, having a forked end, h2, on lever H", which is pivoted to lever H by a pin, h3, and has a tension-spring, h5, at the end'of arm h4, to operate a latch-hook, h6.

HG swings around a pin, hl, on an upright stand, hs, and the forked lever H is fastened to it, so that it can be operated by the rod H3.

The latch-hook h catches against a rod, hg, on the stand which supports shaft E.

The left-hand end of lever H6 is operated by a'cord,

I, figs. 1 and 3, by means of friction on the clutch e5, around which said cord is coiled, and from` whence it passes down to and around.v an intermediate-pulley, Il, and up again to lever HG.

To keep up a certain tension, a spring, I, is attached Vto the cord I, at any convenient place.

Another cord, 13, iig. 3, is fastened to I, and passes up to a pulley, I, on shaft B, to which it is fastened.

This cord I3 is also provided with a tension-spring, I5.

A `small spring, e, on shaft E, serves to push clutch against its mate, e.

Fig. 4 illustrates Athe method of disconnecting the l worm-wheel F lfrom the worm, or screw FZ. This is done by moving a lever, f6, pivoted at f7, and passing through armetallic eye, f", on the bearing f'", which supports shalt Fi. The result will be understood by reference to the gurc in red lines.

Having thus described the construction of my mech anism, I will now explain its operation:

Supposing that a full set of bobbins has been c0111-I pleted, and removed, and the machine is ready to begin spinning again,.the weight D, on the faller and also the faller, are down, and the rod G6 disconnected from the rack G5; now, the operator, by lifting the lever f, disconnects the wheel F'" from the worm F2, and so rotates the Wheel as to mo've the rack Fs to its lll extent in the direction ofthe arrow. Ihis moves the pinion G4, and the rack is thereby moved back, until the tooth y catches into the notch in the rod G, and couples the rack and rod together. y This backward movement of the rack F brings the end of rack FS against the pinfi, which causes the spring F9 tostretch, so that the lever F7 will leave the pinf Y Now the yconnection between .F3 and FE is restored again, and the spinning-machine started anew.

The latch-hook h, being freed by the preceding action of the machinery, the large clutch E2 is off theI clutch-tooth or teeth c, and consequently out of gear with it or them.

The small clutches e* and do not catch, lie-anse the motion is such that they slide against each other.

The whole `taller-arrangement, therefore, remains at rest as long as the spinning-process lasts.

As soon as the frame is run out the required length, the spinning-machine is reversed, for backing off, or unwinding the yarns from the tops of the spindles. This back motion will cause clutch e* to catchelutch ci, and thus pull the cord I by friction, so that it will move the lever H in the direction indicated by an arrow. rlhe consequence is, that latch-hook 7L catches on the rod h, and the forked lever H brings the clutch` head E2 in contact with tooth e, which insures the coupling of the aller-machinery with the driving-pulley E. After this, the machine is reversed again, and the winding-up begins.

The rack F5 is moved in the direction contrary to the red arrow, as seen 'in gs. l and 2, so slowly that only a very small part of way is travelled with each action of the faller.

The cam G2 moves the lever G up, and thereby the connecting-rod Gi' cross-head G" and )inion G* for- Ward.

The rack F3 receives no motion from the rack F6, until F has so far moved that the lever F7, with its lower part, comes in contact with pinf, when it receives a fractional part of the said motion, as long as lever F7 swings around pin f.

From the time .when lever F7 comes in contact with the adjust-able set-screw, or pin f2, the acksF FS move at the same rate of speed.

In this manner, the shape of the bobbin is determined, for it is evident that the motion of the rack F3 is the general feed-motion for all the successive layers of yarn which form the bobbins.

If the rack Fs were stationar Y, one certain tooth on the pinion G4 would, at the beginning of each stroke (See lig. l.)-

of the cross-headl G3, always be in the same relativeA position with its surrounding machinery but, with the motion of Fi referred to, the same tooth, with each stroke, is found to be a little ahead of the position it occupied during the former stroke. lhus the rack G5, which is moved by the pinion G", begins each successive .stroke at a point in advance ofthe former 011e, and, according to this, are the up-and-down movements of the faller gradually higher, until thebobbin is finished.

The reason for beginning the operation by keeping the rack FS stationary, and afterward allowing it to assume the speed of Fj by degrees, isthis, that, by the said operation, a shoulder, or foundation for the bobbin is effected, which supports all the other layers, and the bobbin receives its proper shape, i. e., pointed at the top. i

Each revolution of the cam G2 supplies the bobbin with one layer of yarn, and a new lengthof twisted material.

During the twisting-operation, the faller is raised above the tops of the spindle, and remains inactive. The yarn will be found to be wound up part-ly on the spindle, caused by its own weight, and a slight friction on the spindle,a11d the inclination for fbrn'liugloops, or knots. This has to be removed, or unwound; therefore the machine is reversed.

This motion, besides unwinding the yarn, has the effect of coupling the clutch-head E2 with the main pulley E, in the manner already described. rlhe fallerrod A is, by the same motion; drawn downward, and the rod Glisthereby,moved back until it catches on the tooth g, and couples the rack G with the faller. After this, the machine is reversed again toits former motion, and the faller-arrangement, being effected in the same manner, begins the winding-up operation, by movingl up and down, and guiding the yarn to the spindle with -an irregular motion, or speed, the effect of which is to produce a pear-shaped bobbin.

rlhe shape of this bobbin can easily he altered, or regulated, by changing the circumferential shape of the cam G2, or by setting the set-screw f2 either forward or backward, or .by changing the length of lever F", or by changing the position of pins ff.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. The mechanism for operating the faller, constructed substantially in the manner andjor'the purpose herein described and represented.

.2. l'lhe combination, with the faller of the racks F3 Fi, pinion G4, and rack Gf', all arranged and applied as herein described, and operating in the manner and for the purpose specified.
