FILLING-CUTTING MECHANISM FOR SHIFTING-SHUTTLE-BOX LOOllIS.
Application flled August 21,1924. Sei'ia1'No.-733,256. T
To all whom it may concern: 7
Be it'known that I, EDWARD A. CUNNIFF, a citizen of the United .States, and resident of Waltham, county of Middlesex, State of Massachusetts, have invented an Improve: ment in Filling-Cutting Mechanism for Shifting-ShuttlerBox Looms, of which the following description, in connection with the accompanying drawing, is a specification,
10 like characters onthe drawing representing likeparts. This invention is particularly designed for removing projecting filling ends from the selvage ofcloth' woven in a shifting shuttle box or drop box loom, especially when cross;
bar fabrics are woven. When in the weavmg of such fabrics the stripes or Crossbars woven by one of the shuttles are widely separated, a long loop of filling .is left extendingfrom one bar to the next succeeding bar upon the reparticipation of the shuttle in the Weaving operation. These vloopsof filling must he removed from the selvage to make the fabricsalable and it is difficult, if not impossible, to-remove them bythe usual singeing operations and laborious andexpensive.
to remove them by hand.
The present invention provides means acting automatically during the weaving operationby which such, loops'are first out or severed and then the ends are cutoff close to the selvage. v j a The present invention also provides means acting automatically during the operationiof the loom to remove in a'novel and eflicient manner any filling ends left projecting at the selvage.
These and other objects and features of the'invention will appear more fully from those: parts of the loom directly concerned with a preferred embodiment of the inven- 'tion.
the accompanying description and drawings In the. drawings:
Fig. '1 is a View, in vertical cross-section taken through thelayand breast-beamof a two box shifting shuttle box'loom adjacent the temple and showing a'preferred form of the invention, certain of the parts being broken away. i I
. Fig. 2 is a plan view of the construction shown in Fig. 1 forward ofthe lay and illustrating the cloth being woven.
Figs. 3, 4c, and 5 are perspective views showing successive steps in the weaving of the'cloth andthe cutting of a loop.
' While the invention in. certain of its aspects may beemployed in removing filling vendsfrornthe selvage of cloth being woven in various types of looms it is, as already pointed out, particularly designed for use in connection with aldi'opbox loom weaving comparatively widely separated stripes or bars of filling. 1 I i 1 ..A lay sword 1 is shown supporting the usual layf2, handrail 3, and reed4. The
running shuttle 5 is shown in position on the lay and the positionfof the other shuttle 6 of a two box' loom is indicated in dotted lines in Fig. 1. The, shuttle 6 is shownin of the shuttle boxes the shuttle 6 will take the position on the lay while the shuttle 5 head comprises the usual pod 10 and cap 11 extending transversely of the shank and enclosing the usual temnlerolls 12 which act to maintain the cloth at the required width.
The construction is the same atbothsides of the loom and it is thereforesufiicient to illustrate and describe the construction at one side.v The temple is normally and yieldingly projected rearward by the usual spring. not shown, in the temple stand and is'moved slightly forward at each beat up of the lay 1 by the engagement of the lay with the lheel 13 depending from the temple head. I
The cloth 145 being woven passes fromthe shed through the temple head over the tem ple rolls and thence over. the breast-beam its'inactive position. Upon the next shift and is taken up by the usual take up roll, not shown.
In Figs. 3, 4, and '5 is'illustrated'a piece of cloth in whichnarrow crossbars or stripes 15 are formed by the filling from one shuttle alternating with, comparatlvely first a cutter knife by which these loops are cut'into twoparts and second, a cutting mechanism subsequently acting to shear or cut off the two ends close to the selvage.
The cutter knife comprises a small blade 19 having a sharp rear edge, and
mounted to extend transversely of the plane of the cloth adjacent the salvage and forward of the fell. This position is convenof the cutter kni e and acts to cut I to the selvage, these ends.
iently secured by mounting the blade 19 in aslotted horizontally extending shank 2O adjustably secured by means of the set screw 21' to the top of the temple cap 11.
It will thus be seen, as shown in .Flg. 3, that the last pick of filling 22 in the last stripe 15 woven will be'carrled by its shuttle forward of the blade;19 and will be held by the shuttle in its inactive position. During the weaving of the intervening section 17 y by the other shuttle the cloth will be gradually takenup and the fillin 22 be carried forwardly and beneath the lade-19.' The first pick 23 taken by the shuttle in reparticipating in the'weaving to form the next stripe 15 will pass to the rear of the blade 19 as shown in Fig. 4. There will thus be formed a loop which willbe drawn about the blade 19 as shown in 5 and finally as the cloth is further taken up this loop drawn forwardly against the cutting edge of the blade 19 will be severed, leaving the depending ends such as 24 and 25.
The cutting mechanism for removing the ends at the selva e, whether ends such as 24 and 25 or any ot ers left projecting, has its field of action ad'acent the selvage forward off, close This cutting mechanism is preferably supported from the breast-beam and. oper ated by a hunter carried by the lay.
In the preferred construction illustrated, the bracket 26 is bolted at 27 to the rear face of the breast-beam 7 and presents a rearwardly projectin 1 arm 28 at an acute angle to the 'selvage. n this arm is mounted a stand 29.slotted longitudinally at 30; In
the rear end of the slot is mounteda fixed vertical cutter blade 31 and parallel therewith a vertical guide 32. A hook shaped cutter blade 33' is mounted to slide'and rock in the slot 30 and co-operates at its hooked end with the blade 31. A' plate 34 secured -to the stand 29 and overhanging the slot 30 limits the upward movement of the cutter blade '33. The cutter blade 33 is provided at its forward end with an upstanding arm 35. This arm is in the path of a hunter 36 bolted at 37 to the hand rail 3. A spring 38 engaging a lug3'9 on the arm 35' and'a lug 40 on the stand 29 acts normallyto project the movable cutter blade rearwardly while the hunter 36 acts upon each beat up of the lay to slide and rock the movable cutter blade forwardly and cause it to have a coroperating shearing action with" the fixed cutter blade 31. H
This cutting mechanism is so mounted and positioned that the movable cutter blade is. located immediately adjacent the path of the selva'geand its rearward end'extends, when in open position, beneath the selvagei so that the closing and cutting movement takes place in a direction upwardly and outwardly from the selva e. Thus any fillin ends depending at t e selvage are caug, t and sheared off by the cutting mechamsm. To prevent any filling ends from'bein thrown upwardly a guide arm 41 is mounted on the stand 29 close to the plate 32'and extends above or overhangs the plane, of the cloth. This arm thus acts to restore to the cutting field of the cutting mechanism "any ends thrown upwardly.
The position of the cutting mechanism by which the plane of movement of the movable cutter blade is'normal to the lane of the cloth at an acute angle to the se vage'insures in an effectivemanner the filling'ends being caught and severed.
The position of this mechanism is further determined by adjusting 'it' bodily transversely until the selvage guides a ainst the fixed cutter blade 31 as shown in ig. 2.
i There is thus presented simple and efii- 'cient means readlly attachable to the existing looms secured.
'Having thus described the invention, what is claimed as new, and desired to be secured by whichithe desired results-are by Letters Patent, is:
1. Mechanism for removin long filling loopsfrom' the selva e of clot being woven in a'shifting shuttle ox loom havin a temple comprising a'cutte'r knife carrie by the in weaving is drawn forwardly around the knife and severed as the cloth is taken up in the weaving operation, and cutting mechanism having its field of action adjacent the selvage forward of'said cutter knife and acting to out off close to the selvage the projecting ends of the loop left after severance by the cutter knife.
2. A shifting shuttle box loom comprising a cutter knife mounted on the loom to extend transversely of the plane of the cloth adjacent the selvage forward of the fell and with its cutting edge facing rearwardly whereby the loop of filling formed at the selvage by a shuttle upon its reparticipation in weaving is drawn forwardly around the knife and severed as the cloth is taken up in the weaving operation.
3. Filling and cutting mechanism for a loom comprising a fixed vertical cutter blade located immediately adjacent the path of the salvage, a hook shaped movable co-operating cutter blade extending when in open position beneath the selvage and havin its closing and cutting movement in a d1rection upwardly and outwardly, the plane'of movement of said movable blade being nor mal to the plane of the cloth and at an acute angle to the selvage, and means for intermittentlv effecting the opening and closing movement of the movable cutter blade, whereby the filling ends projecting from the sedlvage are severed close to the selvage.
4. Filling cutting mechanism comprising the construction defined in claim 3 together with a guide arm associated with the fixed blade and overhanging the plane of the cloth and acting to restore to the cutting field any ends thrown upwardly.
In testimony whereof, I have signed my name to this specification.
