THREAD-GUIDE FOR SPINNING-MACHINES.

SPECIFICATION forming" part of Letters Patent No. 270,169, dated January 2,1883,

' Application filed May 5,1882. (No model.)

i To all whom it may concern:

Be it known that I, THOMAS D. WILMAR'IH, of Providence, in the county of Providence and State ofRhode Island, have invented a new and useful Improvement in Thread-Guides for Spinning-Machines, of which thet'ollowing is a full, clear, and exact description.

My in veu t-ion consists in a revolving threadguide, having, the object to relieve the thread or yarn of tension, so and breaking thereof, and to produce a more even and a stronger yarn, as hereinafter described and claimed.

Reference is to be hadtto the accompanying drawings, forming a part of this specification, in which similar letters ot reference indicate corresponding parts'in all thefigures.

Figure l is an elevation showing my improved thread-guide as applied to use. Fig, 2 is a sectional side view of the same. Fig. 3 is an elevation of my improvement, shown applied to that portion of a spinninganachine immediately from which it receives its movement; and Fig. 4 is a side view thereof.

A is the ordinary delivery or fluted bottom roll of a spinning-machine. I

D is the bobbin upon which the thread or yarn is wound, and U is the thread-guide,

placed upon the shaft 0 intermediately of theroll A and bobbin D. The thread-guide G is its mid-length for the yarn, and attached to the shaft by a set-screw, a, or other means.

In operation the thread or yarn passes from the roll A over the guide 0, and from thence to the bobbin. The shaft 0 is to be revolved in the direction opposite to the travel of the yarn, the effect being that the twist is carried to the bite of the roll A, where it is most needed, and at the same time the thread or yarn is relieved of tension at the roll A, so that stietching and breaking is prevented, thereby avoiding waste and making the yarn more even, stronger, and better.

It will be understood that one of the revolving guides 0 will be fitted in connection with each bobbinh For convenience of dofiing or removing the bobbins ot yarn or thread when full, the entire device is to be so arranged that it'may be moved endwise, thereby allowing the bobbins to come off between the whirls.

as to prevent stretching E is a beam, to which is bolted a bracket, J, supporting a standard, K, bolted to the latter and forming one of the bearings for the shaft a, carrying the guide 0.

K is one of the standards which support the fluted roll-shaft.

Around the shaft 0 ot' the guide 0 is placed a spring, 1), arranged between the guide U and the standard K. The springs l), while enabl ng the ready holdingot the bifurcated key D", inserted between the standard K and gear-wheel E when the guide 0 is slid to one side to permit the dotting of the yarn, as indicated in dotted lines in Fig. 3, will also cause the automatic return of the guide 0, with its shaft 0, to its original position.

F G are intermediate gearing for transmitting motion from the gear-Wheel H, ordinarily employed for driving the back rolls of the spinning-machine, to the gear-wheel E of the guide-shalt c'to drive the guide 0 in a reverse direction to the travel of the thread over the fluted roll A. The shafts of the wheels F G are supported in standards I, bolted to side pieces of the frame of the machine, only one of said standards'being shown.

In shifting the guide (3, with its shaft 0, to permit the doffing of the yarn, the gear-wheel E is moved away tiom the standard or support K a distance equal to the width of the key D and thelatterinserted between the said wheel and standard K and-caused to straddle the shaft 0, as seen in dotted bees in Fig. 3. The

gear-wheel E is recessed or countersunk on its outer side to receive the nut which is screwed upon the shaft c for securing the wheel thereon, asshown in dotted lines in Fig. 3.

Having thus described my invention, I claim as new and desire to secure by Letters Paten t- The combination of the roll A, the bobbin D, and the ring and traveler with the shaft- 0,

carrying the guide (J, and gearing E F G H, u C

adapted to drive the shaft in an opposite direction. to the travel of the yarn, whereby stretching and breaking of the yarn is prevented, substantially as specified.
