THREAD-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 644,866, dated March 6, 1900.

Application filed January 7, 1897. Serial No. 618,241. (No model.)

To aZZ whom it may concern:

Be it known that I, ROBERT MORRISON, of Canton,county of Norfolk, and State of Massachusetts, have invented an Improvement in Thread-Winding Machines, of which the following description, in connection with'the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a novel thread-winding machine, my invention being especially adapted for winding silk onto paper or other tubes, thus doing away with headed spools.

To wind large masses of thread on a cylindrical tube, the ends of the thread masses must stand up straight or at right angles to the tube, and the ends must be wound or laid up firmly, so as not to break down by handling or unwinding. To wind this class of thread mass, the thread being wound must be absolutely controlled throughout the whole length of the traverse; and one object of this my invention is to positively control the thread right up to the winding-point. To do this, I have provided a cloth or textile covered roller which occupies a position parallel to the tube on which the thread or silk is to be wound, and the thread being delivered to the tube by a reciprocating thread-guide is acted upon constantly by the rough surface of the cloth and is prevented from slipping and is laid exactly uniform and at the exact point desired on the tube, the thread so acted upon obeying exactly and quickly any change of the thread-guide when the end of the traverse is reached; The tube to receive, the thread is placed on a spindle having at each end two trundles, which are acted upon and driven by a rotating drum.

Figure 1, in cross-section,represents a winding-machine embodying my invention. Fig. 2 is a detail of the thread-traversing mechanism. Fig. 3 shows the pressure-roller, and Fig. 4 the spindle carrying the tube.

The framework is composed of two like ends A, joined by rails or websa CL (L This frame has at one end suitable ears, as a one of which is shown in Fig. 2, said ears receiving a cam-shaft B, rovided with a belt pulley B and a cam the latter acting on a traverse-lever Z), pivoted at 71 and adapted,

to be connectedat its upper end with a suitable traversing bar Z7 provided with one or more thread-guides b the end of said lever being kept in contact with said cam by a suitable spring ZJ The machine has two parallel shafts 13' B each provided with a series of drums or cylinders d, and these shafts are in practice rotated in like manner. As shown, the shaft B has attached to it at one end of the machine a belt pulley D, which is embraced and driven by a belt D. The shaft B is driven in like manner, butits belt and pulley are at the opposite end of the machine The end of each shaft B B opposite that from which it is driven has (see Fig. 2) a spiraltoothed gear B which engages a spiraltoothed gear 13 on a shaft B said shaft having a small belt-pulley which drives the belt B, passedover the pulley B on shaft 13 for moving the thread-guides Z). In the present embodiment of my invention I have shown two of these traversing bars I), and, in fact, each may be worked by its own lever 12'; but inasmuch as they are alike I need describe but one of them.

The cross-girths a support a series of spindles 0, having bearings 0' attached to part of the girth or cross-frame a, the said spindles each having a suitable spool, as 0 upon which is wound the thread or silk t, which is to be taken therefrom and wound on tubes by my machine. The thread i, which may be silk, on the spool c is to be wound on a paper or other tube, as 6, (shown in section in Fig. 4,) and for the purpose of rotating this tube I have provided a spindle 6, having near one end a fixed trundle e and near its other end a removable trundle e the removable trundle being preferably applied to the spindle after the tube has been applied, the removable trundle being screwed on the spindle. The spindle so provided has end journals which rest in suitable notches in brackets o extended from the cross bar or'web a, and the trundles e 6 rest on the drums or cylinders ol, and the spindle is rotated by the said drums.

Referring to the left-hand side of Fig. 1, which shows the preferred form of my inven-. tion, f represents a pressure-cylinder, preferably of wood, covered with a cloth or textile cover f, the journals of said roll entering slots f in a vertical guide f so that as the thread or silk is wound upon the tube of the spindle the said pressure-cylinder may rise vertically. The cloth or textile cover presents a roughened hairy face, which as the thread or silk t is being wound onto the tube acts on the said thread or silk like the finger of the human hand to hold and direct it just at the point where the thread meets as a tangent the Wound mass, and this roughened surface so clings upon and produces friction on the thread, and so prevents it from slipping unduly longitudinally with relation to the length of the tube,the said cloth surface enabling the thread presented by the thread-guide to be controlled directly at the winding-point, so that as the thread-guide changes its position the thread has no opportunity to slip out of this proper path, which is controlled directly by the thread-guide. The cloth surface of the pressure-roll acting on the thread being wound, as described, enables the thread to be turned at the ends of the reciprocations, so as to build up a square-ended thread mass which will not unravel or break down when the tube is removed from the spindle.

I could not lay the thread on the tube and Wind it up with square ends by the use of a smooth-surface, wooden, or rubber-covered roll.

Between the spool c and the spindle containing the tube I pass the thread under preferablya guide h, as shown at the left in Fig. 1, and then lead it through an eye h of a tension-rod h mounted in a bracket 71 and to increase or diminish the tension I may turn the rod 77/ thus winding the thread a greater or less number of times about the rod.

Instead of permitting the pressure-roll to rise and fall vertically, which I prefer, the said roll might be mounted in bearings at the ends of the arms m, pivoted at m.

I denominate as the winding-point the point where the thread being wound touches thetube or the thread mass as a tangent.

This invention is not limited to the exact de= Vices shown for actuating the thread-guides, and instead I may use any other usual or suitable devices.

Having fullydescribed my invention, what I claim, and desire to secure by Letters Patout, is-

1. In a thread-winding machine,a rotatable drum or cylinder, a rotatable spindle having two trundles, one of which is removable, and

having journals extended beyond said trun-' 2. In a thread-winding machine,a rotatable driving-drum, a rotatable spindle having a tube to receive the thread, and two separated trundles at the ends of said tube and in constantlydriven contact \vith said drum during the winding of the thread until the entire thread massis wound, said spindle projecting beyond said trundles, bearings to receive the projecting ends of said spindle and co6perating therewith to maintain said trundles in said continuous contact, a thread guide, means to reciprocate it, and a uniformly-acting pressure-roll having a roughened periphery of textile material located between said trundles and pressing continuously on the thread going onto said tubes directly at the winding-point, guide-bearings for said pressure-roll, said pressure-roll being raised by the thread mass as the latter increases on the tube, substantially as described.

3. In a thread-winding machine, a rotatively-inounted spindle provided witha tube adapted to receive a thread, a roll located above the tube and having a roughened-cloth periphery adapted to bear at all times in contact with the thread upon said tube, and guides or brackets having longitudinal slots to receive the journals of said roll.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT MORRISON.
