2 Claims.

This invention relates to winding frames. employed for winding spools used in therweaving of Axminster rugs.

. The object of the invention isto facilitate the 'y operation of. clamping the strands of ,yarn togetherv after winding and prior to cutting, by the provision of a combination of comb clamp and spool reed of novel construction lwhereby the yarn is guided between the teeth of the clamp m, without the danger of splittingthe individual '1^ strands of yarn by the teeth as has been common heretofore. f l

Fig. 10 is a horizontal sectiontaken on the line ill-I0 of Fig. 6. ,wh As indicated in Fig. 1, the setting frame `of a pair of tension rolls 2 ,and 3 engaging the yarn as it passes from the creel, in the direction incated by the arrow, to the spool 4which is rotated by a plurality of winding rolls 6, 1` and 8, one gli or more of which is power-driven. These details may be variously contrived.

At I have indicated by novel reed, disposed in proximity to the spool 4. It comprises a plurality of dents 3| extending vertically from a 505' mounting 32 which is supported at both ends by levers 33 which yare pivotally mounted, as will appear, to elevate the reed to itsvdotted line position for clamping up the yarn after the run.

, As indicated in Fig. 9, each of the dents 3| is constructedof a strip of metal of uniform Width and thickness, the bottom portion 31 of the front edge of which is twisted slightly out of alignment with the upper portion 38 of the front edge.

60 This twisting operation may be performed by f' my invention is provided, as is customary, with (Cl. .Z8-55.5)

holding securelythe entire rear face 39 of the dent and theny grasping the lower corner 31 of the front face, after-.which the lower portion is bent to the left-as viewed in Fig. 9 and out of alignment with the upper portion 38 of the front 5 face, without bending either the upper portion of the front face, or the rear face throughout its entire area. n*After the dents are bent in this manner, they are mounted in the supporting block 32 at equally spaced intervals,parallel with 10. each other and withmtheir twisted lower portions all curving to the left, as viewed in Fig. 4, in

parallel curves. 1

The supporting block 32 has` -secured to: its front face, adjacent, the bases of the dents 3|, by 15 suitable bolts 34, a block 35 which is slotted at 36 to receive a comb member 40 (Figs. 5 and 8) forming one element of the usual comb clamp adapted to clamp up the vyarn after winding.

The levers 33 supporting the opposite ends of 20 reed 30 are fixed to opposite ends of a rotatably mounted shaft r1| The lever 33 shown in Fig. 1 joins pivotally at with one end of a link 46, the other end of.. which link is pivoted at 41 to arm 48 WhiChisXed to a shaft 50, suitably mounted to rotate.

As indicated in Fig-.2, shaft 43 mounted adjacent shaft 50 carries freely mounted thereon, a cam member which may be in the general shape of a truncatedcone to provide `a tapering 30 cam surface which, gradually diverges from a low portion 62 closely adjacent `the surface of the shaft 43, to a high annular portionf63 formed of `a hub of substantialthickness as compared with the low portion62 of the cam. The cam 60 y, has lugs 65 depending from the enlarged end thereof. Pivotally secured tothe bolt 66 passing though the lugs. 65 is one end of` a link 10 which is pivoted at its otherend at 12 to a link 13. The link 13 is fixed to stud shaft 14 rotatably mounted in lug 15 depending from and secured to the frame -of the machineV in any suitable way.

The links 10 yand 13 form a toggle joint actuated byrotation of shaft 14 to which link 13 is secured and the toggle is provided with a stop 12a adapted to-abut the surface 12b' when the toggle is straightened and a second stop 12e which yabuts surface 12d when link 13 is swung to the left slightly beyond a horizontal position. As indicated in 3, a pinion 11, secured to shafty 14, meshes with a rack 18 pivoted at 19 to a 50 push-pull rod 80,v which has a sliding bearing in the side frame memberl0 of the machine and is provided at its extremity with a hand knob 8| by which the rack may be lmoved longitudinally of the shaft 43.

. Riding on the surface of the cam 60 is a cam follower carried by an arm 82 (Fig. 2) fixed to the aforesaid shaft 50 vby one or more bolts 93.

v'With `the machine constructed as above dew scribed, its operation is as follows: The winding position of the spool reed is that shown in full lines in Fig. 1 obtained by disposingthe cam 6U in its `dotted position of Fig. 2 with stop 12a against surface 12b. Cam follower 90 is now on lower portion 62 of the cam. It will be noted),y

the roll 2 in engagement with roll 3, in amanner from Fig. 4 that the yarn l now passes through the dents 3| of the reed above the lowertwisted portions 31 thereof, in which vposition they strands of yarn guided by adjacent dents,are given ample space 38A for the running of the yarn.

Prior to commencing the winding, the comb member 4!) of the clamp is secured in position in the groove 3%* immediately in front of the dents j 3| lbelow the yarn and in alignment with the bases of the dents. It will be observed by a comparison of Figs. 4 and 10, that the partial. twists of the lower front edge portions 3l of the dents form a plurality of straightline openings for the passage of taut yarn, each of which openings is bounded on one side by the front edge portion 3'! of one dent and on the other side by the rear edge 39 of the next adjacent dent on the left, as viewed in Figs.l 4 and 10. Thus, as a result of the straight line position of the yarn under tension, the twisting of the bottom portions of the dents 3i provides, in eiect, a number of areas 31A for guiding the yarn at the bottom of the dents which are quite narrow as compared with the wide areas 38A at the upper portion of the dents.

The clamping comb 40, when properly positioned in the slot 35 provides narrow spaces 40A, between adjacent teeth, in alignment with the narrow spaces 37A at the base of the dents, with the pointed tips of the comb teeth disposed, as-

indicated in Fig. 5, in alignment with the deflected portions 3l of the dents. To insure this position of the comb, the slot 36 may be of xed length to receive and properly position a comb of corresponding length or, if desired, it may be prof vided with adjustable end portions for varying its length to adjust the position of the comb. At thecompletion of the winding operation,

during which, as stated, the yarn is guided byy spaces 38A as shown in Fig. 5, the push rod 80 (Fig. 2) is pushed to the right, as indicated in that view, to elevate the reed 30 from its full line position of Fig. 1 to itsdotted line position, whereby, in effect, to depress the yarn l into the comb of the clamp and between the teeth thereof.

By this movement of the push rod 80 to the right,l

a clockwise rotation of the link i3 is effected until stop 712e abuts surface 12d which moves the link 'it to the left, thereby pushing the lugs 65 and cam Si) to the left to make the cam follower 9e ride from its lower position at 62 to the elevated position at 63. 'I'his movement of the cam follower elevates the leverl 92 to which it is Secured, to impart a slight rotation to the shaft 5U. This movement of the shaft 50 is imparted to the lever 48 to rotate that lever and the lever 46 (Fig. l) and lever 33 from their full line to their dotted line positions to elevate reed 30 to its dotted line position. As indicated in Fig. 6, this movement in effect causes depression of the taut strands of yarn, first into the narrow passages SIA and thence into the slots A between the teeth of the comb, as indicated at IA, and it willv be observed that during this movement the yarn cannot touch the points of the teeth of the comb. After this operation, the cap B9 is secured over the comb to clamp the yarn in the usual manner, a small length of yarn is drawn off from the creel, the clamp is removed from the slot 36 and the yarn is cut adjacent the clamp. n Y

The operation of drawing off .ar small klength of yarn from the creel may be effected manually after elevating the upper roll 2, or it may be effected mechanically by imparting rotation vto j is removed from the'setting frame (afterv the top roll 'I hasbeen moved out of the way in any suitable manner) an empty spool .is inserted in windempty Vspool andthe winding operation repeated. Prior to the commencement of rotation of the winding rolls, the'reed 30 is dropped frorriitsvr dotted line to its full line position by movement of the push rod 8U to the left, until stop `lila abuts surface 'IZbto position the link 'iii yasindi-` cated in dotted lines in Fig. 2 and to dispose the yarn as indicatedin Fig. 4. A combfclamp is then inserted;

It will benoted that the dents of the ,spoolA reed Sil by being twisted kat their bases present the narrow straight-line apertures 31A without actually diminishing the spaces between adjacent dents at their bases' and I thereby provideample room ,at the base of the reed for the passage ofl knots during the operation of drawing oil yarn from the creel after the spool has been clamped.

I claim: Y a

l. A yarn guiding reed for use with a clamping comb, the dents of said reed being spaced ,from

each other tol form a series of apertures of preing position, the yarn ends are lapped about the i;

for holding the comb spaces in registry withl said ing the reed and the comb holder relative fto the yarn to depress the yarn linto said lower apertures, and yarnjdeflecting means for guiding the yarn past the comb teeth and into the' comb spaces during such movement. l

2. In a setting frame, the combination of a yarn guiding reed having dents spaced to .form a series of apertures of predetermined width along the upper portion of the reed for guiding theyarn during the run of the machine, the lower por-` tions of said dentsbeing deflected out of align? ment with the upperportions thereof to form a lower series of apertures which confine the yarn,`

more narrowly than the upper series,` a yarn clamping comb having teeth separated by'spaces' adapted to register with the lower seriesof apertures, a comb holder xcdly secured to the reed for holding the comb spaces in registry with saidlower apertures, and means for simultaneously moving the reed and the comb holder relative to the yarn to depress the yarn into said lower apertures, the tips of the teeth of the comb being aligned with the deected lower portions of the reed dents so that when the yarn is so depressed it is guided past the tips `of the teeth ofthe comb and into the comb spaces.
