TENSION-REGULATOR FOR SPINNING OR TWISTING MACHINES.-

SPECIFICATION forming part of Letters Patent No. 691,594, dated January 21, 1902.

Application filedI'ebruary 15, 1901. Serial No- 47,480. (No model.)

To aZZ whom it may concern.-

Be it known that LARTHUR OEcIL BUTLER, a subject of the King of Great Britain and Ireland, residing at Wollaston, in the county of Norfolk and State of Massachusetts, have invented a certain new and useful Tension Regulator or Governor for Spinning or Twisting Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to a device in a spinning or twisting machine forregulating or governing the tension of the yarn as it passes from the delivery-rolls through the traveler to the bobbin; and it has for its object to provide a simple and efficient means for producing said result.

According to the present'invention I am enabled to produce a stronger and more elastic yarn and a more uniformly-compact cop or bobbin than has heretofore been produced. Furthermore, by the use of'my invention finer counts may be spun than have heretofore been spun and a bobbin of smaller diameter used than has heretofore been used in machines of a similar character. In addition my invention prevents the ballooning of the yarn, either when spinning or twisting.

The above-mentioned advantages and object of my invention will be more fully set forth and explained in the hereinafter-detailed description.

The invention consists, broadly, of a rotatable governor or regulator attachment for spinning or twisting frames which is capable of an axial or up-and-down movement relatively to its shaft or axle under strain of the yarn, whereby the tension of the yarn may be regulated or governed.

The invention further consists of the novel features of construction hereinafter set forth and described, and more particularly pointed out in the claims hereto appended.

.Referring to the drawings, Figure l is a side elevation of the preferred form of my invention. Fig. 2 is a plan View of the same. Fig. 3 is a plan of the under side, and Fig. at is a view of a vertical section. of a modification .of my invention, and Fig. 6 is a plan view of the same.

Like letters refer to like parts throughout the several views.

Fig. 5 is a viewring, and g the movable ring-rail, all of ordinary and usual construction tisarevolubledisk. kisahollowsplitspindle-engaging sleeve projecting from the nu der sideof said disk, and Z an upright shaft or axle extending from the upper side of said disk.

The parts i, k, and Z are made of metal, preferably of steel.

m is a collar madeof suitable material and detachably connected with tlieupper end of the shaft or axle 1. T a

nis a revoluble or rotatable governor or regulator made,preferably,of steel and loosely mounted on the shaft or axle Z and adapted to rise and fall upon said shaft under strain of the yarn-that is to say, the said governor is capable of an axial 'orIup-and-down movement relatively toits shaft or axle under strain of the yarn.

0 0 denote guides or eyes on the governor or regulator, through one of which the yarn passes.

The above-mentioned device is detachably connected with the spindle, as illustrated in Figs; 1 to 4, inclusive, the hollow split sleeve It being constructed of a suitable size and having such a degree of resiliency that it will fit onto and be held firmly on the top of the spindle, or it may be detachably connected with the bobbin in the same manner that the modification is connected, as shown in Fig. 5.

The'mode of operation of the above device in so far as it has not already been disclosed is as follows: The yarn passes from the de livery-rolls and thread-guide (not shown) through the guide 0, thence over and upon the periphery or edge of the disk 1 and thence through the traveler to the bobbin; When the spindle and bobbin are rotated, the disk z'is also rotated, the pull of the yarn upon the traveler causing the latter to revolve upon the race of the ring. The governor or reguin close contact with the yarn assists or aids the traveler in its rotary movement. \Vhen the spindle and bobbin are rotated at any rate of speed, the pull of the yarn causes the governor or regulator '17, to rise, the edge or periphery of the disk 2 acting as a fulcrum. The greater the pull or strain of the yarn the higher the governor will rise on its axle Z, and when the tension becomes slack for any reason the governor will fall, the rising-and-falling movement or up-and-down movement occurring between the disk 71 and the collar m. It is obvious that by this means the tension on the yarn is constantly regulated and governed, and thereby an even tension on the same is maintained, whereby a stronger and more elastic yarn and a more uniformly compact cop or bobbin are produced. Furthermore, the yarn by being held continually in contact with the edge of the disk 2' (and the latter revolving with the spindle) imparts to the traveler a rotary motion quite apart or in addition to its being dragged around by the bobbin. Thus much of the strain upon the yarn is relieved, and for this reason and the fact that the regulator or governor readily yields to any extra strain that would otherwise break the yarn finer counts may be spun 1 the spindle whenever it becomes necessary to and a bobbin of smaller diameter used.

In the spinning or twisting machines the yarn as it is being built up on the bobbin has a tendency to balloon at a point intermediate the traveler and the delivery rolls. This tendency to balloon is obviated by my device, for besides being held in against the disk the slack is taken up by the weight of the governor it, thus reducing the tendency to balloon to a minimum.

I believe that I am the first person to produce a governor or regulator for regulating the tension and for maintaining an even tension upon the yarn and one that acts automatically under stress of the yarn.

Referring to the modification set forth in Figs. 5 and 6, the disk 19 is the rotatable governor or regulator, made, preferably, of metal and loosely mounted on the axle Z, likewise preferably made of metal and adapted to rise and fall or to move up and down on said axle under strain of the yarn. This up-anddown movement takes place between the collar m and the rotatable ring q, made, preferably, of metal, which is loosely mounted upon the axle Z and rests upon the collar m, secured to said axle. The ring q is provided with the guides or clips o 0", through one of which the yarn passes. The lower portion of the axle Z terminates in the split sleeve is, which is slightly tapered at the bottom and of such a size and having such a degree of resiliency that it will fit into a. recess in the top of the bobbin and beheld firmly in frictional contact with the bobbin. The spindle is shown as projecting into the sleeve it; but it is not necessarily held by the latter. The

mode of operation of this modification is substantially the same as that of my preferred form of invention, except that the modification is shown as being detachably connected with the bobbin, although it might obviously be detachably connected with the spindle, as in Fig. 1, and excepting that in the modification the governor-disk p and the ring (1 are both loosely mounted on their axle, whereas in my preferred form of invention only the governor is loosely mounted upon its axle, the disk L' forming a part of or being rigidly attached to the axle.

In the modification the yarn passes from the delivery rolls and thread guide (not shown) over and upon the edge of the governor-disk p, thence through the guide 0, and thence through the traveler to the bobbin. In the modification the strain of the yarn when the spindle and bobbin are rotated causes both the governor-disk p and the ring q to rotate and the governor-disk to rise and fall in precisely the same manner that the governor n rises and falls. The principle of the invention, however, in both forms thereof is substantially the same, as .will be readily seen without further description.

Both forms of my invention being detachably connected either with the spindle or bobbin the latter may be easily removed from remove it.

What I claim, and desire to secure by Letters Patent, is

1. An attachment for spinning or twisting frames, comprising a shaft provided with means for attaching it to a revoluble body, and a governor or regulator, through which the yarn is passed to the bobbin, m'ounted upon said shaft loosely and capable of upand-down movement on said shaft as the latter revolves, substantially as described.
