HENRY WILLIS AND GEORGE RICE, OF WORCESTER, ENGLAND.
Letters Patent No, 91,891, dated June 29, 1869;
IBEPRQVEMENT IN MACHINES FOR WINDING- THREAD, c.
'The Shedule referred to in these Letters Patent and making part of the Ilm-B- To whom it may concern:
Be it known that we, HENRY WILLIS and GEORGE RICE, of Worcester, England, have invented certain new and useful Improvements in Windel-s for Sewing- Machines; and we hereby declare thc following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specitication.
Our improvements relate to winders for sewing-machines, and their object is to guide `the thread, while being wound lon the spool, so as to cause the said thread to be wound uniformly on the spool.
Winders made according to our invention may either be used in connection with sewing-machines, so that the winding of one spool may be effected by the machine itself, while the thread on a previously-wound spool is being used, or the said winders may be used apart'l from sewing-machines. f
To enable those skilled inthe art to understand and use our invention, we will now proceed to describe the same by reference to the accompanying drawings, in which-f Y Figure l represents, in perspective, a windcr constructed in accordance with our invention.
a a are the uprights of the winder, iixed to the base-plate or suppolt b.
, c is the axis or spindle of the Winder, between which and the centre, c2, (which may be made adj osta-ble in Y the ordinary manner,) the spool, upon which the thread is to be wound, is fixed.
Motion is given to 'the spindle c by a band or cord from the sewing-machine, or other convenient source ot' power, passing over the pulley, cl, on the said spindie.
On a sliding bar, e, which passes through one of the uprights a, and is arranged in a line parallel with the spindlesc ci, carrying the spool, is fixed the guideand tension-plate g, through one or more oi the'holes in which plate, according to the degree of tension desired, thethread being wound passes.
The saidtension-plate g has a reciprocating. sliding motion given to it in.the following manner:
Below, and parallel with the bar c is another sliding bar, f, mounted in the frame of the winder; and the two bars are-connected by the slotted arm h. y
In the slot is held the head of a crank pin, k, mounted on the face of a toothed wheel, l, which receives motion from the toothed wheel p.
Motion is transmitted from the axis or spindle c, which gives motion to thespool, to the toothed wheel 11,'by the worm m, gearing with the worm-wheel n, upon the axis of which worm-wheel n the toothed wheel p is situated.
The toothed wheel p is of a nearly-elliptical figure, the longer diameter of the said wheel being somewhat less than twice its shorter diameter.
The wheel l, with whichY the said elliptical wheel p gears, has nearly the'shape of the figure 8, or an hourglass shape.
By the rotation of the toothed wheel l, a nearlyuniforip reciprocating sliding motion is given tothe carrying-frame of the guide and tension-plate g, and the thread is wound V,upon -the spool with great uniformity, the shape of the toothed wheels 'p and l cansiug the movement. ot the tension-plate arm or frame to be reversed quickly, and the crank-pin to rotate with a speed quickest` whenthe tension-plate q is about being reversed, and slowest when the tensionplate is in the middle of each stroke.
Tension on the thread being wound on the spool may be produced by means oi' pressure on the large reel of thread, in addition to that produced bythe tension-plate, this pressure being produced by a spring, s', arranged as shown inthe drawings, or by other suit# able means. 1
In order to arrest the revolution of the spool when filled with' thread, I mount the' driving-pulley ldloosely on the spindlec, and so that it may have a limited Sliding mot-ion thercon,sufticient to cause the piu T, which it carries, to engage with or be disengaged from the pin s, on spindle c, according as the pulley is moved toward or away from the latter pin.
It is held away from the-pin by av spring, aand is. Yforced up, t-o engage with the pin, -by means of an arm, w, shown in Figure 2, mounted upon the sleeve or bearing, in which the spindle c is held, so that its end, w,rnay be turned, when desired, down between the upright a and the contiguous face of the pulley d,
so as to i'orce the latter outward, to engage with the pm s. v The other end, fw, ofthe arm w, is bent to a hookform, and hangs over the spool, ,so that when the lat ter has received the propel' quantity of thread, and is of the desired size, it will come in contact, while revolving, with the teeth formed on the under side of the hooked end, and thus turn the arm w, so as to throw the part w out from between the pulley and the upright a.
The spring t will now throw back the pulley, thus disengaging it from the pin s, and the spindle c will, consequently, cease to revolve.
Y What we claim, and desireto secure by Letters Patl ent of the United States, is
1. The combination, with the guide and tensionplateL-and the frame r arm to which the same is attached, of the elliptical and 8-shaped gear-wheels, as described, connected with said slotted frame or arm by a crank-pin, so as to communicate to the frame a reciprocating movement, and receiving motion from the shaft of the Winder, substantially in the manner and by the means herein speciiied.
2. The device for arresting automatically the rotation of the spool, inrcombination with the winderspindle and its driving-pulley, arranged and connected together substantially as and for the purposes specified.
