ROLLER TRAVERSE MOTION FOR SPINNING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 451,764, dated May 5, 1891.

Application filed October 28, 1890. Serial No. 369,590. (No model.) Patented in England December 19, 1888. No. 18,547-

To all whom it may concern:

Be it known that we, GEORGE HURST, residing at Preston, in the county of Lancaster, England, and JOHN FENTON, residing at Ashton-on-Ribble, in the county of Lancaster, England, both subjects of Her Majesty, the Queen of Great Britain, have invented a certain new and useful Improvement in Roller Traverse Motions for Spinning Machinery, (for which we have obtained Letters Patent in Great Britain under date of December 19, 1888, No. 18,547,) of which the following is a specification.

This invention relates to improvements in the traverse motion of spinning machinery, whereby the objectionable cuts or hollows which are so soonworn in the intermediate rollers by reason of the changes of direction in which the threads or yarns are moving taking place each time on the same part of the rollers are obviated and the object of this invention is to do away with the repeated changes at one point, and consists of an improved device, whereby the number of times that the yarns or threads move to and fro between the rollers before coming to the original starting-point can be regulated and varied as desired.

To clearly explain the nature of ourinvention, reference is made to the accompanying drawings in which Figure 1 is a plan view of our improved varying traverse motion. Fig. 2 is an end elevation of the same, showing the bracket by which the motion is secured to the frame end of the machine. Fig. 3 is a diagram illustrating the to-and-fro motion and how the change of direction of the traverse is made every time at a diiferent part of the roller until the whole has been traversed.

According to our invention we employ a bracket 1, which is fixed to the end of the spinning-frame, and on ashaft or stud secured to this bracket 1 is mounted a worm-Wheel 2, driven by a worm 2 on the back-roller shaft or any other convenient moving part.

011 the axis or stud of the Wheel 2, or on a long boss of the same, is a pinion 3, gearing with and driving the wheel 4, carried on a stud 7, secured to the bracket 1, before rnentioned, and on the axis of the wheel 4 is mounted an adjustable eccentric consisting of disk 5, in which is a slot 6. The stud 7 of the wheel 4 passes through this slot, said stud being screw-threaded and carrying a nut 7 which is screwed down on the disk 5, whereby the position of the latter is fixed.

Pivoted on the eccentric-disk 5 is the finger or lever 8, to which is attached the traverse rod 9, connecting the finger 8 to the guideeye. The beak or arm 8 of the finger 8 is actuated by a cam 10, having three or any othernumber of throws mounted on the long boss or axis of the Wheel 2. The traverse rod 9 conveys the motion to the guide-eyes and traverse, to which a spiral spring is attached, thus keeping the lever 8 against the cams 10. It will readily be seen that, although the earns 10 on the axis of the wheel2 give a regular motion to the cranked lever 8 and traverse rod 9, the eccentric-fulcrum 5 of the lever 8 gives in addition an ever-varying motion to the traverse.

The advantage of the above-described traverse over the ordinary one consists in the fact that it does not admit of a concentration of wear on one portion of the surface of the rollers, but insures a regular distribution over the whole surface, whereby the latter is kept even and true, so greatly addingto the utility and efficiency of the rollers, preventing the wearing hollow and cutting of the leather covering of the intermediate rollers 11, (see Fig. 3,) causing them to wear quite level and true, and consequently the rollers will last a much longer time than usual. The spinning is also improved, and a more even or better yarn or thread is produced. This is accomplished by causing the to-and-fro motion to keep changing upon a different point on the intermediate rollers 11 and allowing no dwell in one place, (see Fig. 3,) as shown by the diagram, where it will be seen the motion changes its direction several times before having finally crossed the intermediate rollers 11 and has a similar action on its return, and each time it crosses and recrosses its various changes are made on different points until the whole surface has been traversed and has had an equal amount of wear both as regards points of change of direction and. traverse of yarn over the surface of the rollers.

That we claim is 1. The combination, with the traverse-rod 9, of a lever having a beak or arm connected to said rod, an eccentric for imparting a motion to the lever, a cam operating on the beak or arm for imparting a second motion to the lever, and gear-wheels for connecting and operating" the parts, substantially as described.

2. The combination, with the traverse-rod 9, of a lever-8, having a beak, a cam for operating on said beak and imparting a motion to the rod, means for imparting motion to the cam, an adjustable eccentric for imparting a
