WILLIAM F. I-IA'UPT, 0F ORANGE, NEW JERSEY, ASSIGNOR OF ONE-HALF TO CLARENCE S. A. WILLIAMS, OF SOUTH ORANGE, NEW JERSEY.

THREAD-SPINNING MACHINE.

Application filed May 17,

T 0 all whom it may concern Be it known that I, WILLIAM F. HAUP'r, a citizen of the United States, and a resident of the city of Orange, Essex County, New Jersey, have invented certain new and useful Improvements in Thread-Spinning Machines, of'which the following is a description.

My invention relates to thread spinning machines and more particularly to improvements in the feed roller mechanisms which feed the fine threads downwardly from their respective spools to the spinning devices in such machines.

In the manufacture of s un threads as it has heretofore been carrie on, considerable wastage of material results from the breakin of the fine single threads which are finally spun into the finished thread. This is principally due to the. frictional wear on the threadby its engagement with the feed rollers of the feed roller mechanisms and with the aligning or spacing bar which is located between and above such feed rollers, and to the fact that the ends .of' .the threads, once they are broken, are likely to come in contact with and be drawn into the gearing of the feeding mechanism. The losses which are thus caused are very appreciable, and where the spun threads are of high grade, expensive material, such as silk, are extremely serious. Moreover, much of the spun or finished thread manufactured at the present time is very imperfect due to the wearing, catching and tearing of the thread by reason of its engagement with the feed rollers and the aligning and spacing bar referred to above.

Among the principal objects of my invention are to prevent ractlcally all wastage and losses such as above described, and to roduce the finished spun thread, especially in the case of silk thread, in substantially perfect condition, or at least to a degree of perfection heretofore unattained.

' My invention further contemplates an improved construction for attaining the foregoing objects, which is preferably in the form of an attachment capable of being readily :gplied to spinning machines now in use. uch attachment is preferably removably mounted so as to be readily replaceable, and also preferably mounted for such adjustment as may be necessary to ensure the proper meshing or engagement of Specification of Letters Patent.

the feed roller gears with the corresponding driving gear.

Other objects and features of my invention will be hereinafter more fully described and claimed.

In order that my invention may be more clearly understood, attention is directed to' the drawing accompanying and forming a part of this specification, and in which:

Figure 1 is a view in front elevation, partly in section, of one of the feed roller mechanisms of a silk spinning machine illustrating the application of my invention thereto; 1

Fig. 2 is a sectional view,'partly in elevation, taken on line, 2-2 of Fig. 1, looking in the direction of the arrows;

Fig. 3 is a sectional view taken on line 3', 3' of Fig. 1, looking in the direction of the arrows;

Fig. 4 is an enlarged view in front elevation of one of the feed roller ears of the feed roller mechanism shown in Figs. 1, 2 and 3;

Fig. 5 is a View looking from the right in Fig. 4;

Fig. 6 is an enlarged central, longitudinal, crosshectional view of one ofthe feedroller gears with the feed roller mounted thereon; and

Fig. 7 is an enlarged detailed view, in elevation and partly in section, improved spacing and aligning bar and mounting.

Referring to the, drawing 1, 1 represent the fine,raw, silk threads, which are'respectively drawn, from spools (not shown) on the spinning machine through tripper hooks (not shown), and then pass together down through the usual porcelain guide 2 which is supported on one end of an arm 3 adjustably secured to the usual vertical trip.- per rod 4, as by means of a collar 5 and set-screws 6. From the guide 2 the threads are conducted in the-'form of a single or combined thread 8 over horizontal feed partly of my its rollers 7 and downwardly to the usual spin- The hook or bar 9 while substantially horithe tripper rod 4 from its properly spaced pin-

.deleterious effects are zontal, has a slight downward inclination and serves as a guide to maintain the thread 8, in its several turns around the feed rollers, and aligned. Two gears or rollers 7,.. 7, are normally in engagement with and driven by a gear 11 fixed to the main horizontal dllVlDg shaft 12 of the ma- L The

feed rollers

7, 7,

feed roller gears

10, 10 and the spacing and ali ning bar or hook 9 are all carried by a rame 13 secured to the vertical tripper' rod 4 in a manner which will be hereinafter described.

In case any of the fine raw threads 1, 1 breaks, the tension on the corresponding tripper hook (not shown) is released, the latter drops and in turn releases the tripper rod 4, whereupon the tripper rod is automatically raised or thrown up, carrying with it the frame 13, and thereby effecting the disengagement and separation of .the

feed roller gears

10, 10 and the. driving gear 11, in a manner well understood. In order to ensure the proper engagement or meshing of the feed roller pinlons 10, 10'with the driving gearll and also to render it extremely easy to replace the frame 13 and age, wear or other damage, adjustably and the frame is also removably mounted form of a horizontal guide 14, and a collar 15 rigidly attached to the rod 45, as by means extension or bracket 17 a horizontal guide-we guide 14 engages. X

a screw 19 extends through a slot 2O in the extension 17 and is threaded into the projection 14 of the.

frame 13. The loosening of screw 19 permits, the frame 13 to be easily adjusted to

gears

10, 10 with the sufiiciently to disengage the. same from the guide or rojection 14. I The frame 13 may according y be easily and quickly replaced by a similar frame carrylng like parts, without involving the necessity of moving normal position in the splnning machine.

' The feed, rollers heretofore used in mechanisms of the character shown and described erein, have usually been made of steel. 'Such rollers, however, are easily worn by silk and consequently the surfaces thereof quickly roughen and then wear, tear and catch the fine silkthreads or fibres. These further increased by ich serve to drive the feed,

the parts carried thereby in case of breakin shape and size with the 'sary to frequently replace due tOxtllO'ffiCt that they The

feed roller gears

10, 10 are rotatably mounted on steel rods 21 driven at one end into the frame 13, and each of'these gears is provided with a long, laterally extending hub 22, which is irregular in cross-section and through which the rod 21 extends. Preferably the hubs 22 are square in cross-section, although such crosssection may be hexagonal, elliptical or of other non-circular shape. The hubs 22 are also preferably tapering, and thus when square in cross-section, as shown, they will have the form of truncated yramids. The cylindrical feed rollers, 7, Q are made of porcelain and molded with axially extending openings which substantially correspond gear hubs 22. Porcelain rollers provided with such 0 enings may be very readily molded. Eac of the

rollers

7, 7 is kept in place on the re spectlve gear as by means of a. screw 23 threaded into the outer end of the corresponding rod 21 and awasher 24 disposed between the head of the screw and the adjacent ends ofthe gear hub and roller, the outer end portion of each roller preferably being recessed as indicated at 25 to receive the washer. and the head of the screw. B-

reason of the cross-sectional shapeand taper of hubs 22 and the openings through

rollers

7, 7, the latter may be pushed tightly onto the gear hubs,-and when the screws 23 and against' anyrotary movement with respect to the

gears

10, 10 without danger of the rollers being broken.

Porcelain thread "aligning and spacing bars have heretofore been used in mechanisms of the character described herein, but prior to my invention it has been necesthese bars as they are often broken. In addition to the expense and trouble directly involved in such replacements, this results in serious losses insthe time of operation of machines vided with such bars. The reason for the frequent breaking of these bars is probably are of small crosssection and have usual the feed roller frames by securing one end thereof directly in openings provided therefor in such frames. In order to obviate y been mounted on 2, 4, 5 and 6 and which prothis objection, I provide a guiding and spacing bar 9 (referring to Fig. 7), preferably in the form of a hollow cylindrical tube provided with an outer hook end 26. This bar 9 is secured to the frame 13 by a headed rod 27, preferably of steel or other metal, which extends through and fits loosely within v the opening through the bar, andhead of the said rod, so that the bar will be securely held in the position shown. It will be apparent that transverse strains on the bar 9 will be transmitted to the metal rod 27 and that the danger of this bar being broken in the operation of the machine is therefore extremely slight.

Another and a very important feature of my invention resides in the construction for effectually preventing the threads being drawn into the gearing in case,for example, any of the fine threads breaks and the frame 13 is automatically moved upwardly to disengage and space the feed roller gears 10, 10 from the driving gear 11-, as explained above.

\ For this purpose I preferably form the frame 13 as a hollow guard for the feed roller gears 1.0, 10 and driving gear 12, by providing the same with imperforate top and vertical side, and rear walls, and a vertical front wall 30 having only a pair of circular openings 31, which are only a very little greater in diameter than the feed rollers and through which the inner end portions of these rollers extend. A hollow guard 32 member formed with top, front and rear walls is also provided for covering that portion of the driving shaft '12 below and adjacent the

feed rollers

7, 7, this member extending a considerabledistance forwardly from the vertiml front wall 30 of the frame 13 substantially at fight angles thereto and being rigidly secured to the frame so as to move upwardly therewith when the same is automatically raised by reason of the thread breaking. Preferably, the guard member 32 is made an integral part of the frame 13. The rear guard wall 33 of frame 13 is slotted at 34: so as to straddle .the shaft 12, and while the guard comprising the frame 13 and member 32 is open at the bottom, all of its walls, with the exceptions noted, are solid or imperforate, and all of its vertical walls extend down a considerable distance below the shaft 12. Accordingly, every part of the gearing and the driving shaft 12 with which broken ends of thread passing through the feed roller mechanism are at all likely to come into contact, are completely enclosed or covered at all times, regardless of whether the frame 13 and the parts carried thereby are in lowered or raised position. Losses due to broken threads being drawn into and entangled with such gearing and driving shaft are thus completely and effectually eliminated. In the construction shown, the frame 13 with its top, side, front and rear walls and the guard member 32 formed integrally with the front wall 30 of the frame, constitute an integral one-piece guard.

It will be seen that the frame 13 and the parts carried thereby, which embody practically all features of my invention, comprise an attachment capable of being readily applied to spinning machines in use. Such attachment when once applied to a machine is also capable of being quickly and easily replaced and may be readily adjusted on such machine for the purposes hereinbefore described.

While I have shown and described my invention as applied to a silk spinning machine, it is not limited in its application either to machines forspinning silk thread form or construction. It is also to be understood that the various features of my invention are subject to various modifications and changes in the number, size, shape and arrangement of parts without departure from the spirit of my invention and the scope of the appended claims.
