This invention relates. to Axminster looms, and particularly to improvements in the. mechanism employed for conducting: the pile yams to the 1 weaving point.

' In looms of this. type, the pile yarns are carried in a large number of separate tube frames, one

, for each row of pile tufts, and each having a spool on which the yarn is woundand a set of tubes which assists the wiping-in of the pile miyarnj between the ground warps. These tube 1 frames are conveyed to the loom above the weav- -ing point on a chain carrierwhich heretofore hasmoved intermittently to cause each successive link or: section of the chain carrying an individual tube frame to pause in a predetermined position above the weaving point during the interval necessary for certain transferring" mechanism to removethe tube framefrom the carrier, conduct it to the weaving point and myreturn it to the'carrier, after which the carrier is advanced another linker section for the transference-of the next succeeding tube frame, and

soon.

The. intermittentmovement of the carrier carrying' the large number of heavy tube frames is obviously a disadvantage in the loom operation but, has heretofore been considered necessary be i cause of the operation of the transferring mechanism. It is the primary object of the presentinvention: to improve on the loom operation by dri'ving the carrier with tube frames continuously at a predetermined constant rate of speed rela- "tive to the weaving cycle and to that end I have devised transferring mechanism having the ;'capacity' of taking a tube frame from a section of V the carrier when it is in one. position, conductingit'to the weaving point and returning it .totne same section of the carrier after it has reached an advanced position; 7 r

Asindicated. in Figs. 1 and 2 of the drawings, the; loom is of the Axminster type and has the usual take-up roll lcdisposed in front of the breast, plate 2 to the rear of which reciprocates the lay 3' operated through the linkage 4 and 5 bya cam on. the cam-shaft 6 in the usual manner. The needle is indicated at I and the shuttle at ll.

main shaft 6 carries on the needle side a bevel gear I meshing with a bevel gear ll secured. to the: end of a shaft l2 containing universait joints l3-and connected through the gearing in housing l5 withthe shaft 20 which drives the; spool chains 2|. Within the housing 15 is a bev'elfgear '22,.fixed to shaftv l2 and in constant its periphery at 3| to receive the trunnions 32 (Fig.2) on a forked arm 33 shifted by hand lever 34in an obvious manner to shift clutch 33 into selective engagement with clutch face 2530121 to rotate shaft 20 either forward or reverse relative to the loom shaft 6. Shaft 20 carries fixed to it, on both the needle and shuttle sidesof the' loom, gears 35 which, as indicated imFig-. 4, mesh with gears 36 and 31 on shafts 0 and, respectively, The shafts 40 and 4| feed of the spool chain 2i so that after weaving one-half of a rug, the same tube frames delivered in reverse order to the weaving point,

may be utilized to weave the remaining half of the rug.

is a speed reduction of three to one so that the shaft 20 rotates one-third as fast as the loom shaft 6. same speed as that of shaft 20. To correlate .the initial position of the chains 2I relative to that of the loom shaft 6 for either forward or reverse movement of the. chains, each of the clutch members 3|, 26 and 21 has three teeth.

As will appear, chains 2| move continuously during the weaving, rather than intermittently as heretofore, and when the chainsmove in the direction of the arrow in Fig. 5, the-tube frame 65a, for example, will be taken from the link 6| when it is in the position indicated in Fig. 5 and will be returned to the link 6| when that link, which is moving continuously, has advanced to the position there indicated for the link 62. My purpose in providing two sprockets 50 and 5| on separate shafts rather than a single sprocket, disposed at the lowermost point of each chain, as heretofore commonly employed, is to provide a substantially horizontally moving chain course near the weaving point having two or more tube frames for the purpose respectivelyiof disengage ing a tube frame from the chains and releasing to the chains a tube frame which has been returned, each arm I2 is pivoted at 13 to a member M and the rear of each arm I2 is connected by a link 15 to a lever 'I6 pivoted at] to a strap I 00. fixed to shaft I8 secured at its opposite ends to the opposite members 14 (see also Fig.9). The

lever I6 is swung by link 86 pivoted at!!! to the lever and at 8| to .one arm of a bellcrank lever 82 rotatably mounted on the pivot 86 carried by a boss 8'! projecting from the loom frame; .From the other armrof the bellcrank lever'extends the link 84 which, as indicated in Fig'sil, 10 and .11, extends to an arm '83 pivoted to shaft I05 and having a follower 88 riding on a cam 89 fixed to the 100m shaft 6. The cam 89 has a low portion' 39a and a high portion89b. When follower 88 is on low portion 890., as indicated, the clutches I0 are closed on the ends'of a tube'frame and the clutches are opened by elevation of the follower by high portion 89b of the cam which effects counter-clockwise movement of lever "I6 (Fig. 9)

resulting in inward swinging of the-rear ends of clutcharms' l2 .and an outward swinging of their front ends carrying the clutches The shafts 4B and 4| rotate at the This movement of the clutchesco-operates with fastening elements on the ends of the tube frames inthe manner indicated in Figs. 6 and 7. Each tube frame 60 carries at each end an upwardly extending bracket having a tongue 96 of a width and breadth to be received freely between the pair of link elements 2 la and 2 lb forming a link of the chain and the bracket carries riveted to it at 9i a spring latch 92 having a shoulder 93 which, because of the outward resilience of the spring latch 92, holds the tube frame 60 in the links 2Ia and 2H) by abutment of'the shoulder 93 with the link element 2Ia. In the train of gears connecting the loom 'shaft 6 and the chain driving shaft 20 there As indicated in Fig. 7, the clutch l0, upon. being moved inwardly against the end of the tube frame 69 in the manner above described, presses inwardly on the spring latch 92 to release the shoulder 93 thereof to release the tube frame from the chain. I have indicated such release by showing the links Hat and Zlbas slightly ele-' vated in Fig. 7 from their position in Fig. 6, but this relative movement has been effected by the released tube frame 60 having been carried downwardly and toward the weaving point by the clutches H! by certain mechanism now to be described. I

.The members '74 which support the clutch arms I2 at the pivots 13 are fixed to opposite ends of. the; shaft I8 as above described, and they are swung vertically about the axis of shaft 18 by a rod IOI (Fig. 10) pivoted at I62 to the member 14 on the shuttle side of. the loom and at its other extremity pivoted at 903 to a lever IM- loosely mounted on shaft I 05. The lever I04 carries a cam follower I06 riding on a cam III], the details of the configuration of which will be described more fully below but which in general is effective to elevate and depress the arms i l in an amount sufiicient to carry the tube frames, released from the chains as above described, to the weaving point and return. a

As stated above, the chains 2I move continuously during the weaving operation and, assuming the chains to'be progressing in the direction indicated by the arrow in Fig. 5, the link SI of the chain will advance from its position indicated to the position now'occupied by link 62 while tubeframe 69a is being taken from the chain, delivered to the weaving point and returned to the chains. To provide this necessary movement of the clutch members It toward the front and rear of the loom, I mount the shaft 18 to which the members '54, carrying the clutches are secured, on levers I 20 secured to a shaft I ZI extending across the loom and journalled in the loom frame. Rotational movement of the shaft l2| for the purpose of swinging the clutches 16) toward the front and rear of the loom is effected by a lever I25 secured to the shaft 62!. which lever is pivoted at I28 to a link I 26 which is in turnpivoted at I21 (see also Fig. 3) to one end ofa lever I35, pivoted intermediate its ends at I3I and carrying at its forward end a cam follower I32 riding'on a cam I35. The cam I35 is fixed to and. driven by the aforesaid shaft '20 and, with the chain progressing in thedirection indicated by thearrow will rotate counter-clockwise as indicated.

With the parts in their positions indicated in full lines, the tube frame 60 is in the weaving position both in Figs. 3 and 5, although, it should be noted that in Fig. 5, for clearness, the'chain' which to trace the movements-of the. tube frame as it is taken from the chain, wiped in and returned, this. pivot will start at the position He, when the tube frameis being released from the 5' chain, and will move along the arc. I40 to the full line: weaving position 1|, the are being the resultant of the forward movement effected'by the cam I35-and the downward movement effected After the wipe in I follower I32' (Fig. 3) and the linkage connect- .ing'it tov the clutches indicate their positions when thetube frame is at the weaving point and itiwill be observed that the follower I32 rests on 25; an elongated dwell at I.35. After a slight pause the follower'during which the frame is lifted toll-b for the draw-off and cut, the follower will be elevated by arise I350 tomove the several links and pivot 11- from their full line to their C posi- 3Q fil15f 'iihehigh portion I350 of the cam has a suflicient dwell to allow for opening of the clutches 'toreleas'e the spool to the: chain, after which g the cam follower I32 descends to the lowest portion I351: of the cam, through the influence of a spring lfiiconnecting the frame and the bell crank: arm I25, to m'ove the parts to their a positions; thereby moving the clutches to take the next tube frame froin the chains, after which the parts move to their full line positions, the neces forward movement of the point 1| being effected by rise of the cam follower on the cam portion I35. .The cycle is thenrepeated and it will be observed that one cycle occupies one-third of a: revolution of cam I 35 in accordance with r the thre'e to one speed reduction between loom shaft Iiandshaft 20 carrying cam I35.

I T ,The vertical components of the movement of I elevation of the arms to the chain is. indicated diagrammatically at IIIIc on the cam. The details of the construction-of this cam are as usual 'andqare only diagrammatically indicated in the drawings. r p .,;'I'he-cam 89,,shown in Fig. 11, which effects the Opening and closing of the clutches on the ends" of the tube frames, is secured to'the shaft c in the position relative to cam no, indicated in'Fig. sothat' the rise 8912 which opens the clutches is effective at the interval in the cycle when' the rise II-Dchasraised the clutches to the .chains.

' When nearingv theend of the yarn on the spoolsfthe yarn on. azfew of the s'poolsiwill fre- 7oz quently becomeexhausted before the yarn runs out on the remaining spools. v It iscustomary in .that'event to continue the weaving and to sup- 1i plyithemissing row of pile tufts which. was intended to come from an empty spoolb'y insert- :5. inganadditional' row of tufts' from an-adjacent :As stated, the full line positions of the cam spool'still having yarn. Although this will distort the. pattern somewhat, the practice is not objectionable unless carried to extremes.

For this: purpose I provide for a double tuft row insertion from any given tube frame by a shifting of the cam followers I06 and 88 onto a pair of cams which repeat the weaving with the same tube frame. As indicated in Fig. 1, the loom shaft 6 carries, adjacent the cam IIIl, a second cam [His and, adjacent the cam 89, a second: cam 89s.

The shaft I05 on which the cam follower levers and I are pivoted, has collars I to prevent longitudinal movement of the cam follower levers relative to the'shaft and the shaft is slidably mounted. in the frame of the loom. The end of the shaft, asindicated at I1I, has pivoted to it the lower end of a. depending lever I12 fixed to a shaft I13 to which a shift lever I14 is also secured. With the lever I14 in the full line position of. Fig. l, the cam followers I06 and 88 will rest on the cams III! and 89 for the normal running cycle of the loom. To cut in a tube frame twice to replace an exhausted frame, the lever I14 isshifted to the left as indicated in dot-dash lines which will shift the cam followers I06 and 88 to the cams Us and 89s. The cam IIOs, as indicated in Fig. 13, has a low portion IIIJt of the same height as the low portion III! of the cam of'Flg. 10 and it has a rise IIDr which elevates the follower I06 the same amount as the rise III") of cam I It. In cam IIIIs, however, the rise by, corresponding in length to the rise IIOc of cam III) raises the tube frame from the Nb position toward the chain by an amount which, while insufficient to return the tube frame to the chains, yet is sufficient to expose the weave for inspection, if desired, by the operative.

The cam follower 88 which controls the opening and closing of the clutches is also shifted to maintain. the: clutches in closed position during the entire loom cycle. For this purpose the cam ass- (Fig. 12)" consists merely of a circular disc of a-radius corresponding to that of the low portion sea on cam 89.

' During thisrepeat operation of any given tube frame, the chain travel continues and the empty tube frame in the chain behind the frame which is cut in twice is removed manually from the chain to make room for the return to the chain of the tube frame which was used twice. The lever I14 is then shifted to its full line position and. thereafter the normal sequence of operation obtains I As is well. known, it is customary to tilt the tube frame 60 during the wiping in operation of the tuft yarn. As indicated in Fig. 5, the clutches/13 which, as stated, are pivoted at H, are. pivotal-1y connected at 20!! to a rod 20! on both sides of the. loom, each of which rods is pivoted at. 202: to a lever 203 fixed to a shaft Z'IEIYWDOSE opposite ends are journalled in the lower ends of levers I20. Near the shuttle side, Fig. 10, the shaft 212 has fixed to it a lever 2I3 which is elevated and depressed by a lever 284 leading to a lever 255 4mg. 14) pivoted at 201 and'having a follower 286 engaging cam 2H1. Elevationrof the follower 295 by the cam 2H] will-tilt the clutches 16 and tube frame in a clockwise direction about the pivot 10 as viewed in Fig. 10- and in a counter-clockwise direction about that pivot as viewed in Figs. 5 and 3. The major portion 2M of the cam is of constant I have found that apparatus constructed as above described operates effectively for the pur-' pose intended of correlating, with the Weaving cycle, a continuous movement of the tube frame carrying chains. In my apparatus there is sufii-. cient play between the links and the tube frame supporting brackets to permit the withdrawal and insertion of tube frames while the chains are moving. However, if necessary, a slight movement of the clutches with the chains can readily be effected by providing the necessary additional cam portions on the surface of cam I35.

t willbe noted that when the direction of travel of the chain carrier is reversed to reverse the order of presenting the tube frames, the rotation of cam I35 is also reversed so that the movement of the clutches horizontally is correlated to the reversed direction of travel of the carrier. However, the main camshaft 6 always rotates in the same direction and thereby the raising and lowering of the clutch arms 74 the opening and closing of the clutches and the tilting of the clutches for the wipe-in, are unaffected their sequence of operations by the reversal of the shaft 2t driving the chains and the cam I35.
