THREAD GUIDE FOB SPINNING MACHINES.,

vApplication led June 21,

To all whom it may concern.'

Be it known that 1,RIOHARD V. BUTLER, a citizen of the United States, and residing at Old Forge, county of Lackawanna, State ot Fennsylvania, have invented certain new and luseful Improvements in Thread Guides for Spinning Machines, ot which the following is a specification.

v T his invention relates to spinning Amachines and particularly to machines l'or spinning silk and its obj ect is to providera guide mechanism for use in combination with the usual eed rolls oi' such machines.

v1n silk spinning machines it is customary to employ feed rolls arranged in pairs each pair comprising a front and rearroll arranged substantially parallel and mounted in a suitable frame. lhe threads ot' silk in any desired number are generally caused to pass downwardly in iront 0i the front roll and after being wound oneor more times around each roll are led aw ay from the iront roll and caused to pass to other parts ot the machine positioned beneath the rolls. It has been 'found' that when the threads are thus 'carried downwardly directed 'from the front roll or when they are allowed to pass over any considerable portion ot such roll immediately before passing downwardly they are liable tobecome entangled with the adjacent wraps ot' thread on the roll or to be caught by the front roll itself, with the result that the threads are wound about the rolls which necessitates stopping the rolls `and cutting the threads therefrom thus causing a loss of time as well as a loss of valuable material. My invention aims to overcome theseV difficulties by providing a guide mechanism which is arranged in iront ot the usual rolls and so positioned as to receive the threads after they leave the rolls. This guide mechanism is so arranged as to lift or hold the threads out ot' Contact or any ex tended contact with t-he front roll as the threads are passing from the rolls to the guide and downwardly to the other mechanism oi' the machine.`

v@ne speciiic embodiment of the invention is described in the Jmllowing specilication and illustrated in the accompanying drawings, in which:

Figure 1 is a side view showing a portion of a spinning machine containing the usual Specification of Letters Patent.

1921. Serial No. 479,338.

feed rolls and also having my improved i 55 Figure 2 is a iront view of the construcv guide mechanism attached thereto;

tion shown in Figure 1;

Figure 3 is a plan view of the same; and

Figure 4 is a sectional view on the line L -4 of Figure 3.

Referring tothe drawings in detail 10 represents a supporting member provided with side lugs 11 between which the roll carrying frame 12 is arranged, this frame being provided with front and rear bearings 13, 1li, within which the rolls 15 and 16 are rotatably mounted. These rolls are provided at their ends with gear teeth 17, 18, which mesh with a common driving gear 2O indicated by dotted lines in Figure 1. Between the rolls 15 and 16 there ,is arranged an inclined guide 21 which is suitably secured to the frame 12, this guide serving to keep the threads separated as they pass around the rolls. As shown in Figure 1 the threads are usually led through a suitable guide 22 and into contact with the i'ront roll 15 from which they pass around the rear roll 16 and after one or more turns'about each of the rolls the threads are ledv downwardly to other parts ol the spinning machine.

The mechanism thus tar describedvis old and well known. 1n my improved construc- Patented Apr. 18, 1922.

tion Iprovide a bracket 25 which is suitably secured as by means of a bolt 26 to the supporting member 10, this bracket extending forwardlyand upwardly and at its upper end being provided with spaced arms 27, 28 between whichthere-is arranged a suitable guide 30. This guide is preferably made otf glass or porcelain or other suitable vitreous material andthe same is positioned at an angle to the axis oi the iti-ont roll 1.5, the purpose ot' such inclination being the same as that oit` the inclined guide 21 heretofore mentione'd, namely it tends to keep the threads separated from each other thus avoiding entanglement of the same. rlhe guide 30 may be rigidly secured in the arms 2i. 28 or, if

' Zontal plane as the upper surface of the rear roll 16, the result being that` the upper surface or periphery of the front roll 15 lies slightly beneath a straight line connecting the upper surface of the roll 16 and the guide 30. By this arrangement it will be apparent that as the threadsI leave the rolls and pass to the guide 30 they will be lifted or held out of contact with the surface of the roll l5 and also ,held away from the adjacent wraps of the threads ypassing around said roll l5.

It will be e understood that the terms front and rear as applied to the rolls l5 land 16 are employed merely for convenience of'. description and are not to be taken as indicating any particular position of the rollsand the guide 3Q in space. The front roll may be regarded as the one arrangedjnearest the guide and the rear roll the one farthestfrom the guide. y It is also to be understood that the axes of the rolls linstead of being arranged in a horizontal plane, as illustrated in the drawing, may be arrangedfin a plane inclined to the horizontal and that the particular angles at which the Athreads are led to and. from the rolls are immaterial. I

By thus lifting and holding the threads o utofmcontact with the front roll 15 and away lfrom the adjacent wraps of thread on thev rollsit has been found that the threads will notbewcaught bythe rolls or become entangled with adjacent threads. As heretofore noted, in the case of prior construetions suchentanglement of the threads or catching -of the sameupon the rolls results in wrapping the vmaterial about the rolls thus requiring that the machine or rolls be stopped untilthe'entangled material can be cut therefrom. With my improved guide device applied to a machine these difliculties are largely avoided, the rolls can be operatedmore steadily and require less attention and loss of time in cutting material from the rolls andloss of valuable material are to a considerable extent obviated. Y

Having thus described my invention what I claim las newv and desire to secure by Letters Patent is: y

i l. ln a 'spinning machine having feed rolls and means for driving. the same to wrap threads thereon, the improvement which comprisesa guide yarranged adjacent one of said rolls over which guide the threads are adapted to pass when carried out of contact with the rolls, said guide being positioned above the axis of the roll ad'- jacent which it is arranged. Y

2. ln a spinning machine having feed rolls arranged side by side and means for driving the same, to wrap threads thereon, the improvement which comprises a guide arranged adjacent one of said rolls over which guide the threads are adapted to pass after leaving the rolls, said guide being positioned to hold the threads away from the roll adjacent to which it is arranged as the threads pass from the rolls.

3. ln a spinning machine having feed rolls and means for driving the same to wrap threads thereon, the improvement which comprises a guide arranged adjacent one of said rollsover which guide the threads are adapted to pass after leaving the rolls, the upper surface of said guide being arranged above the axis of the roll adjacent which the guide is mount-ed and positioned to hold the threads out of contact with saidv roll as the threads pass from said rolls.

e. ln a spinning machine, in combination,

feed rolls about which threads are adapted to be wrapped, means for driving said rolls, a guideI for receiving and guiding the threads after they pass from said rolls, said guide being arranged adjacent one of said rolls and positioned above the axis Vof "the roll adjacent which it is mounted. `i

5. In a spinning machine, in combination, a front feed roll and a yrear feed roll, means for supporting and driving said rolls to wrap threads thereon, a guide arranged lin front of said yfront roll over which guide the threads are adapted to Vpass after leaving said rolls, said guide being positioned to hold the threads above the surface ofthe front roll as they pass from the rolls and means for supporting the guide. d

6. ln a spinning machine, in combination, a front roll and a rear roll, means for supporting and driving said rolls to wrap threads thereon, a guide arranged in front of said front roll over which .guide lthe threads are adapted to pass, the upper sur face of said front roll being arranged beneath la straight line connecting the upper surface of the rear roll and said guide, whereby the threads are lifted out 0f contact with said front roll as they pass to said guide, and means for supporting the guide.

7. ln a spinning machine, in combination, a front roll and a rear roll, means for supporting and driving said rolls ,to Wrap threads thereon, a guide arranged in front of said front roll over which the threads are adapted to pass after leaving-said rolls, said guide being inclined to the axis of said front and rear rolls with the upper surface of the latter arranged above the upper surface of the former and also having an inclined guide arranged between said rolls, the improvement which comprises a guide arranged in vfront of said front roll and having its upper surface so positioned that a straight line extending therefrom to the upper surface of said rear roll will pass above said front roll, said guide being inclined in substantially the same direction as the aforementioned guide between said rolls.

l0. In a spinning machine, in combina.- tion, a front roll and a rear roll, means for driving said rolls to wrap threads thereon, a guide arranged in front of said front roll for receiving the threads as they leave said rolls, the upper surface of said front roll being positioned below a plane parallel with the axis of said rear roll and passing through the upper surface of said rear roll and said guide, whereby the threads are lifted out of contact with the front roll in passing from the rear roll to said guide.

ll. ln a spinning machine, in combination, two feed rolls arranged adjacent to each other, means for rotating said rolls to wrap thread thereon, a guide arranged adjacent one of said rolls over which guide the thread is adapted to pass as it is leaving the rolls, said guide being positioned to hold the thread away from the surface of the roll adjacent to which it is arranged as the thread passes from the rolls.
