' is capable of serving as an effectual clearing device and whichv atv the same time"v serves to place'upon the running thread a fixed amount oftension. i
Other objects are toprovide.aRc nstructionfor the device Which is simple in character; which renders thedevice capable of beingreadily cleaned, and whi'ch will effect a. breaking of the thread in the event a slub or other irremovable obstruction is encountered; T In. the accompanying drawings Figure 1. is aside elevation taken from .the righthand side ofFigz. 3.
. Fig. 2 isa vertical sectional viewtaken in the plane of line 22 of Fig. 3.

Fig. 4 is a fragmentary plan view of cer tain thread guidingmeans comprised in the device. I
The device herein shown is adapted for use in connectionwith a winder of the type disclosed in the Colman Patents No. 1,267
977and No. 1,274,386, granted May 28, 1918, and August- 6; 1918, respectively.- Itwill be apparent; however, that the device is also adapted for use with other forms of spoolers and winders. My combined yarn tensioning and clearing device comprises, in the preferred form illus trated, a pair of plates 5' and 5 providing two'opposed, smooth, curved surfaces 6 and .6f'between which the running. thread is arranged to pass. Said plates-are respectively supported' at their upper ends by a pair of shafts 7 and 7 arranged in. parallel relation and mounted in two upright supporting members 8 and 8 of a U-shaped frame 9. The plates arebent along one edge so as to partially encircle the shaft 7 and 7, the latter beingpreferably polygonal in shape, and from said shafts the, plates depend downwardly and toward each other with the surfaces 6 and .6 disposed in opposed relation at the lower edges of the plate. When used with a winder of the typeshown in the before-mentioned Colman patents the plates are arranged out of contact with each v 19 of the member 19 vwhich thus constitute other as indicated in Fig. 1; 1
The U-shap'ed frame 9 is mounted preferably upon a flanges 11 at ront and rear edges and anchoredto a suitable support 12 by means of two or more screws 13. A second plate 14" having upturned flanges 15 isentered between the base and the plate 101 The two plates are thus spaced apart vertically. -The frame 8' is secured to theplate 10'1by means of a bolt 14. An. upturned flange 11 is formed'on the left hand end of theplate, 10 against which the frame is bolt 14. 7
Means is provided for guidingthe thread in its passageupwardly between t and tensioningplates hand 5. consists of a shoulder 16 formed on a laterally extended end portion] ofthe plate 10,
and a forwardly o ening notch 17in a laterally extended en portion of the plate 14. The notch is made of substantial depth and is a greaterwidthat its forwardend in order more readily to receive the. thread. The forward edge'of the plate 10 is shaped to provide an outwardly and rearwardly inclinededge18' for guiding the thread into the .notch- 17 in placing athread in the devlce. r
Between the upright members 8 and 8 of. the frame '9' is inserted a generally U- 'shaped member 19 having an upwardly extendingportion forming aspring clip 20 adapted to. engage with a pair of rods 21and 22 secured'between the members 8 and 8 plate 10 having down-turned he clearing .This means held by the near the'upper ends thereof. The rods 21 1 and 22' are located oneabove' the otherand engage with the clip 20'to hold the member 19 against turning. At the upperend ofthe clip 20' itmaybe shaped as at 23 to receive andclamp the upper'rod21'.
The rods. 2l'and-22 are extended laterally .to the right as shown in Fig. as is also a third rod 24 positioned directly below the rods 21 and 22. 25 are detector fingers coacting with the rods 21', 2'2 and 24 which form a station'arygrid between which and thedetector fingers the thread passes.
The plates 5 and 5 are yieldingly held with their lower. curved ends 6 and 6 in the desired relation to each other by a pair of'plates26, one on. eachof'the shafts 7 and7, engaging the depending side portions and 7 and thus move the surfaces 6 and 6 7 and 7 to rock, all corners are sufficiently rounded, the apertures in the members 8 and passes it -ment of the finger.
8 being circular in form.
Any suitable means may be employed tov limit the movement of the plates 5 and 5 toward each other by the leaf springs 19. Herein I have shown for this purpose a finger 27, one end of which is mounted in an aperture in the upright frame member 8, large enough to permit of a rocking move- The'other end of the finger is slidablein vertically disposed slot 28 in the upright'frame member 8'. Be tween itsends the finger is flattened and provided with an aperture through which bolt 29 anchored at its lower end in the base of the frame member 9. A coiled expansion spring interposed be tween the frame member and the finger serves to hold the latter against the head of the bolt 29. By adjusting the bolt the position of the finger relative to the plates 5 and '5 may be readily determined, it being observed that the finger engages inclined surfaces 5" on the plates above the curved surfaces 6 and 6. Thus a nice adjustment of the distance between the surfaces 6 and 6 may be obtained, the distance varying in accordance with the'amount of tension which it is desired to maintain on the thread, until the full force of the spring pressure is exerted against the plates and the thread. In any case a fixed amount of tension will be maintained upon the running thread by the frictional engagement of thethread withthe surfaces 6 and 6. Also, particles of extraneous matter on the thread will be cleared therefrom; and in the event that a relatively large and irremovable obstructionon the thread attempts to pass between the plates, a breakage of the thread will result because of the inertia of the parts combined with a substantial stiffness in the leaf springs 19 which hold the plates against opening or separating when the obstruction is encountered.v
To enable the device to be quickly and easily cleaned of matter accumulated between the plates 5 and 5, the shaft 7 is extended slightly beyond the left hand end of the U-shaped frame 9 and provided with a forwardly extending lever 81. This lever may be operated manually, but is adapted to be operated mechanically as by a cam bar of the traveling mechanism shown in the Colman Patent No. 1,267,977.
' To facilitate the placing of the thread in the device and to insure that it shall not be obstructed in this operation by the forward plate 5, the latter is shortened at its right hand end as is shown clearly in Fig. 3 as is also the shaft 7. The curved guiding surface 18, it will be observed, projects slightly beyond the plate 5 but terminates short of the end of the plate 5'. Thus in placing the thread in the device it is guided laterally and rearwardly by the surface 18 beyond the end of the plate 5, whence it springs laterally to the left betweenthetwo plates as permitted by the guiding edge 16 (Fig. 4:), the'latter being disposed approximately in the vertical plane of the inner end of the notch or slot 17 in the lower plate 14, and also in the plane of one side of the guide finger 24 above the plates5 and 5'.
To permit of access to the screw 29 for purposes of adjustment, an aperture 32 is provided in the forward side of the member 19 (Fig. 2). I
I claim as my invention a 1. A combined yarn clearing and tension ing device having, in combination, a pairof parallel shafts located one in front of the other in laterally spaced relation, a pairof v plates having their upper edges secured upon the respective shafts and depending therefrom and shaped to; provide at'their lower edges opposed curved surfaces, spring means tending to move said plates toward each other, and a stop finger vertically adjustable between said plates and'adapted to limit the movement of said curved surfaces toward each other by the action of said spring means. i
