APPARATUS EMPLOYED IN THE MANUFACTURE OF ARTIFICIAL SILK.

Application led September 5, 1919.

To @ZZ whom it my coni-cm:

Be it known that, I, JAMES CLAYTON, a

subject of the King of Great Britain, residing at 12 Middlesborough Road, Coventry,

in the county of Warwick, England, have invented new and useful Improvements in Apparatus Employed in the Manufacture of Artificial Silk, of which the following is a specification.

My invention relates to machines .em-

ployed in the manufacture of artificial silk,

- sage of the thread into the spinning-box.

I have found that the operation of initially passing, or threading, Athe thread through the thread-guide,` or funnel, is much facilitated, especially in cases where it is desired to run the machine at ahigh Speed, if means be provided whereby thethread is, during the threading operation, subjected to the action of a drawing-roller guide, or Godet, which has, during such operation, a circumferential velocity slower than that which the drawing-roller guide or .Godet has when the thread is passing thereover on its way to the spinning-box during normal working of the machine. My invention is especially adapted, for instance, for use in an apparatus in accordance with m-y invention the subject-matter of application, Serial No. 309509, A. D. 1919, for Letters Patent, in which apparatus, the ordinary drawing-roller guide, or Godet, can be run so much more quickly than is done in Tdinary machines that, without some provision according to my present invention, the/full advantage of greater Speed of outputwill not be practically obtainable owing to the difficulty, of passlng the thread through the thread guides, or funnels, when the drawingroller guides, or Godets,are running at high Speed, but my present-invention is not limited, in its application, to apparatus of this Specification of Letters Patent. y

particular kind as it can be employed with ordinary machines and enable these to be run at higher speed than hitherto.

According to my present invention I p rovide means wher eby,`when the threads are to be passed through the thread-guides, or funnels, the said threads can be passed over drawing-roller guides, or Godets, (all of which I will refer to as Godets) caused to rotate at the required slower circumferential speed. For this 'purpose I provide means whereby the Godets havedilferent species of rotation which I will describe, with reference to the accompanying drawings, premising that I do not limit myself to the precise details illustrated.

Figure 1 shows`A in vertical transverse Section, and Figure 2 in side elevation, sulicient of the upper part of a machine to yillustrate the application of my invention thereto when I employ an additional Godet, upon 7a shaft separate from that of the ordinary Godet, over which the thread passes, through the thread-guide, or funnel and into the spinning-boxwhen the machine is normally at work. Figure 3 Shows a modification wherein the additional Godet is connected to the ordinary Godet.

.Like parts in all the figures Aare marked with the same reference numerals.

Referring first to Figures 1 and 2, the spinning boX is marked 4 and the 'threadguide or funnel is marked 17. The ordinary' Godet is marked C and is shown as being driven by a scroll-wheel n on the shaft N, engaging a scroll-wheel c2, on the shaft c, of the Godet C, which shaft c, is carried in the long tubular bearing c1.

P, is an additional Godet, provided in accordance with my present invention. It

is shown as being mounted on the shaft 0' (carried in the long tubular bearing p1) which has on it a Scroll-wheel p2 which en-Y gages wit-ha scroll-wheel g, on a Shaft Q,f[

which is driven, 'byany suitable gear at a slower circumferential speed than that at which the Godet C is driven.y This can, for example, (assuming the Godets C and P to be, as shown, of equal diameter) be conveniently effected by reducing gear conveying motion from the Shaft N to the shaft Q,-or, if desired, the additional Godet P can be of a diameter So muchsmaller than the diameter of the ordinary Godet C, that the Godros erts Cv and P can be driven at the same speed and have the desired difference in rate of circumferential velocity.

I do not limit myself to any particular relative speeds, but I may mention that satisfactory results are obtainable if the Godet P be driven. at a circumferential velocity of 125 feet per minute and the Godet.

ferred from the Godet P, to the Godet C, (asindic/ated at y in Figure Q) and coiling of the thread into the spinning-box` proceeds.

The troughs q1 and channels r2 are for carrying liquid which drips from the Godets, into the space below and thence away to any suitable receptacle, or place.

InFigure 3 I have shown the additional Godet P formed in one with the ordinary Godet C, but ofsuch smaller diameter that the Godet P will have the required slower.

circumferential velocity.

What I claim is 1.!In apparatus for spinning artificial silk, orthe like, a spinning device and driven` roller guide means having different peripheral speeds, and over which a thread may be passedLalternatively at higherpor lower speed, to the spinning device, the roller guide of lower peripheral speed affording means which facilitates the initial feed of the thread to the spinning device.`

2. In apparatus for .spinning artificial silk, the combination lof a spinning box, a guide funnel for leading thread into the spinning box, and driven guide roller means having different peripheral speeds, and over which a thread may be passed to the funnel alternatively at higher or lower speed, the roller guide .of lower peripheral speed-affording means which facilitates the initial feed of the thread to the spinning device.

3.111 apparatus for spinning artificial` silk, a spinning box, a pair of independent guide rollers, and means for driving -the same at different peripheral speeds' to.afford alternative feed means for leading a thread at higher or lower speed to the spinning box, the roller guide of lower peripheral' speed aHording means which facilitates the initial feed of the thread tothe spinning device.

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