THREAD GUIDE FOR SPINNING MACHINES.

Application fiIed, June 9,

To all whom it may concern.

lie it known. that l/VILLTAM FnTZEn,.l VIL- LIA M CONNOLLY, and HENRY Fnrznn, citizens of the United States, residing at Scranton, 5 in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in Thread Guides for Spinning Machines; and e do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to spinning machines, and particularly to machines for spinning silk. In silk spinning machines it is customary to employ feed rollers arranged in pairs, each pair comprisinga front and rear roll arranged substantially parallel and mounted in a suitable frame, the threads of silk in any desired number being passed downwardly in front of the front roll and looped a number of times around the two rolls, and are finally led away from the front roll and caused to pass to other parts of the machine positioned beneath the rolls. The threads are liable to become entangled with the adjacent threads as they leave the front roll on their way to the machine beneath the rolls. It has been proposed to overcome this trouble by providing a guide arranged in front of the usual rolls and so positioned as to receive the threads after they leave the rolls.

In one type of guide mechanism the guide proper is supported in an inclined position between a pair of upright fingers, which extend from the top of a bracket secured to the frame forming a part of the roller support. It has been found, however, that this type of guide mechanism is not free from objections. The threads on being received on the guide proper tend to slide down the inclined guide and rub against the finger which supports the lower end of the guide, with the result that threads are frequently broken. The threads in passing downward are also inclined to rub on the shank or butt of the bracket from which the guide supporting fingers rise.

This invention has for its object to provide an improved form of guide mechanism in which the guide proper is preferably horizontally disposed instead of being arranged at an incline as has been proposed, and also to mount the guide in such a man:

1923, Serial No. 644,382.

ner that the downwardly directed threads will not come into rubbing contact with the support or bracket which carries the guide proper.

It is also an object of the invention to secure the guide supporting bracket in such a manner that the guide may be firmly positioned with respect to the rollers.

The above and other novel features of the invention will appear from the detailed description taken in connection with the accompanying sheet of. drawing forming a part of this specification.

In the drawings, Fig. 1 is aside view showing a portion of the spinning machine containing the usual feed rolls and also having the improved guide mechanism attached thereto; Fig. 2 is a vertical cross section of the device shown in Fig. 1; Fig. 3 is a front view of the construction. showing Fig. 1;- F g. 4 1s a horlzontal sectlon taken on line 4.-l Fig. 3; Fig. 5 is a plan view of the device shown in Fig. 1, the rollers and guide being shown as removed from their supporting means, and Fig. 6 is a perspective view of" the bracket which supports the guide- "dotted lines in Fig. 1.; It will be understood that the shelf 11 has a slot or opening' through which the gear 20 extends.

Between the rollers is mounted an inclined guide 21, which is suitably secured to the frame 14, this guide serving to keep the threads separated as they pass around the rolls. As shown in Fig. 1, the threads are usually led through a suitable guide 22 and into contact with the front roll 18 from which they pass around the rear roll and after one or more turns about the rolls, are led downwardly to other parts of the spinning machine.

T e me hani m thus far desc i ed is e14 and well known. The present invention aims to combine with the above described structure, a guide over which the threads may pass as they leave the rolls for passage to othenparts of the spinning machine. This guide comprises a porcelain member 23, which is preferably of reduced diameter between its ends so as to present a concave surface over which the threads may ride. The guide 28 is substantially parallel with the axis of the adjacent roll and is disposed somewhat above the upper surface of the said roll. v

The guide 23 is supported on a pin 2a, which is suitably secured to the upper end of a finger 25 which projects from an angular saddle block generally indicated at 26.

Referring now to Fig. 4, it will be seen that the member 10 has an outwardly ,ex-

'* tending bench-like member 27, Which on the inside face of the member 10 forms a channel into which a part of the gear 20 may extend. To the bench-like member 27 is secured the saddle 26, one angular side a of the saddle having an opening therein through which a screw 28 may pass for securing the saddle to the support 10. The side b of the saddle is disposed against one side of the member 27.

By mounting the guide 23 in the manner indicated, there is no liability of the thread rubbing against the supporting bracket as is the case Where the guide is supported between a pair of fingers. Furthermore, the guide is held in a fixed and definite position with respect to the roller supporting frame since the bench 27 is engaged by the saddle on' two of its sides. By making the guide 23 of reduced diameter between its ends, the threads will tend to ride to the lowest part and maintain that position.

By use of the improved guide, the threats will not become entangled and consequently a great saving in time and material is eittected in running the machine.

What is claimed is:

An attachment for a spinning machine comprising an angular saddle having a finger rising from the corner thereof and a laterally extending guide at the top of the finger, said guide extending in a direction away "from the saddle, one of the sides of the saddle having an outwardly extending inwardly curved extension.

In testimony whereof we afiix our signatures.
