WEFT-IARTER DEVICE FOR- LOOMS.
Application filed November 15, 1923.
" upon detecting depletion of such volume to the predetermined minimum. The expulsion of the old practically emptied weft or filling carrier from the shuttle, which occurs .as a fresh reserve loaded carrier is introduced into the shuttle, leaves a length of the old weft or filling extending outward to the eye of the shuttle from the adjacent selvage of the cloth that is being woven. Two parter arrangements areemployed in L a feeler loom. One of such sets is combined with the socalled shuttle-feeler, and is caused to operate to part the said outwardly extending length of old weft at a point adjacent the mouth of the shuttle-box which is occupied by the shuttle at the moment of replenishment. Such arrangement is known usually as the shuttle-feeler weftparter. The other arrangement, known as the temple weft-parter because applied to the temple at the side of the loom at which the replenishment is effected, is operated to part the old weft again at a point close to the selvage. The shuttle-feeler weft-parter is provided with clamping means by which, after the parting of the old weft or filling by such parter, the outer end of the portion extending outward from the selvage is held so as to prevent such portion from dropping or flying about, and so that, as the shuttlefee ler goes forward after the shuttle-feeling action and the action of its parter, the said portion is drawn forward into the range of action of the temple weft-parter.
Heretofore in practice the fixed and movable blade-members of the shuttle-feeler weft-parter, working against each other like the blades of a pair of scissors, but not designed to cut the portion of the old weft or filling intended to be clamped and held Serial No. 674,886.
thereby until reopening of the said weftparter and clamp at the time of the next shuttle-feeling operation, have been made of metal. Certain drawbacks exist in such case, which it is the purpose of the present invention to obviate. I
The invention consists in a weft-parter clamp having the stationary member or blade thereof made of one of the well-known varieties of chemically modified paper material known as fiber.
A shuttle-feeler of well-knowi1 form provided with weft parter and clamping devices including the invention is shown in the drawings, in which latter,
Fig. 1 shows the same in side elevation.-
Fig. 2 is a view in horizontal section on line 2, 2, of Fig. 1.
Fig. 3 is a view in vertical section on line 3, 3, of Fig. 1.
The shuttle-feeler 1 is constructed at 2 suitably for application in connection with a pivotal mounting in association with the bobbin magazine or battery of a bobbinchangiug automatic replenishing loom. As usual, the end-portion 3 of said shuttlefeeler is designed to be acted upon by the tip or shoulder of an endwise misplaced shuttle projecting inward toward the middle of a loom from the shuttle-box on the lay at the replenishing side of the loom. This end-portion has a horizontal open-ended slot Or notch 31, with its opening facing rearward, to'receive the length of old weft or filling extending from the selvage outward to the shuttle. At 4 is the fixed lower cutting blade of the parter device, and at 5 is the vertically movable upper cutting and clamping blade, arranged to cooperate at its inner side with the fixed lower blade 4 in parting the said old weft or filling, and at its outer side with the fixed clamping member 6 in clamping the adjacent end of the portion ofold weft or filling that extends between the shuttlefeeler and the selvage. The clamping member 6, composed of fiber in accordance with the invention, has an open-ended notch or slot 61, with its opening rearward, to receive the old weft or filling. As usual, in the descent of the movable blade 5 the one angle of the lower edge of such blade coacts with the fixed cutting blade 1 to part the old weft or filling. At the same time, such edgecarries an Ill) adjacenbportionvof the said weft or filling down below the upper edge 62 of the lower .projection 63 of the rear end of clamping member 6, bending such portion of the weft or filling around the said projection, withont cutting the weft or filling, so that the extremity of the latter becomes clamped between one side of the movable parting blade 5 and one sideot the clamping member 6.
lheclainping member composed of fiber acts eitcctivelv in clamping the oldweft or filling. At the sametime it is free from the liabilit-y tocanse cutting and consequent release of the portion of weft or filling which should be held by it which occurs in the case of; metal fixed clamping members.
At 7 is :a tensionspring, constituted by a leaf spring, which isin contact with the outer face of theifiber clamping member 6. The parting, and clamping blades or members nre held in assembledrelations with the shuttle-feeler bvmeans of a bolt 8, which serves as a pivot for the movable iparting blade, and a rivet 9. To provide for the requisite swinging lmovement of the movable parting blade :21 hole 51 is madeitherein around the rivet 9, to permit play of the said blade relative to such rivet; and as heretofore in some cases the upper portion of the movable cutting blade is. furnished with a lateralprojection :52 whichis suitably engaged to swingsuclvbladeinto open position as the shuttle-feeler swings rearward in aloom, while the bladeis furnished with a downward projection or :too 53 for contact with the loom lay to close the blade for the parting and clamping action.
The tension spring 7 is concaverl and disposed with its concave side next the fiber clamping member so that it bears by its ends against such n'iember, in order that in consequence of tightening of the. bolt 8 the clamping and parting members or'blades may be elastically pressed together and toward the adjacent side of the shuttleteeler, to ensure good parting and clamping! action. To reenforce both the upper and the lower rearward projections of the fiber clamping member, and keep both of said projections pressed against the movable parting member, the rear portion of the tensionspring is forked and one branch thereof bears laterally against the lower projection 63 of said clamping member while the other branch hears laterally against the upper projection above the notch or open-ended slot in such member.
What is claimed as the invention is \Veft-parting and clamping devices coinprising". in combination, a fixed parting blade, a fixed clamping member composed of fiber and having an open-endedslot or notch, a. movable combined parting and chunpinp blade or member between said fixed blade and fixed fiber member and cooperat= ing therewith respectively, and a tension spring having rearwardly extending branches bearing laterally against the upper and lower projecting portions of the fiber clamping member.
