Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed April 25, 1914. Serial No. 834,337.

To all whom z't may concern Be it known that we, BENJAMIN WVALKER and ALFRED SPINK, subjects of the King of Great Britain, residing at 81 Leopold street, Leeds, England, and Pearson Terrace, Hyde Park, Leeds, England, respectively, have invented new and useful Improvements in or Relating to Looms for Weaving Pile Fabrics, of which the following is a specification. v

This invention relates to looms for, weaving pile fabrics and it relates particularly to looms for weaving warp vpile fabrics and having the pile forming wires arranged longitudinally of the fabric.

In looms of this kind it has been proposed to have the pile forming wires fixed in such manner that their rear ends are movable and I to move each said rear end by means of a reed of special construction from one side to the'other of the path followed by the end of pile warp pertaining to the wire, so that by moving the rear end of each wire from one lateral position to the other thewarp end pertaining thereto alternately passes down'opposite sides of the said wire and thereby the loops are formed without displacing the pile warp from its vertical path.

The chief object of the present invention is to provide a loom of the above stated kind in which the parts are'adaptedto be moved accurately and without danger of injuring the warps. i

According to this invention means are provided whereby the rear end of each pile forming wire is locked in its lateral position. During the forming of the loops the pile forming wires areliable to be moved downward,.or sag, at their rear ends, and to take this up means are provided for carrying the said ends upward to their normal position verticallythatis to say, for bringing the rear ends of the wires into alinement and thereby insuring that all the pile forming wires are firmly supported at one level dur-' ing the time the pile endsare being formed over the said rear. ends. .After being raised to their normal position the rear ends of the -wires arelocked. The rear ends of the said wires'are adapted to move betweenstatiom 'ary vertical guide blades or members each arranged between the vertical paths-of the pile warp'ends, the end of each pile forming wire is movedlaterally f'romone side to the other of the path of the pile warp end pertaining thereto by means of a deflector. The statlonary vertical guide blades or members between which the pile wire ends are moved are provided with resilient, or yielding, or movable sections against which the wire ends come incontact, when the said sections yield sufficiently to cause the non-contacting side of the pile wire to become approximately flush or in alinement with the non-movable portions of the stationary vertical guide blades Or members thus insuring the pile wire being taken up by and locked within the locking device.

In the accompanyingdrawings Flgure l is aside elevation, partly in section, of one construction of warp pile loom according to this invention. Fig. 2 is a' front elevation of a portion of the same, certain parts being removed. Figs. 3 and 4: are respectively a vertical section and a plan showmg, on a larger scale, some of the wires and certain parts pertaining thereto. Figs. 5 and 6, 7 and 8,'and 9and 10 are respectively side and front elevations showing the parts in their various positions that they assume during working. Figs. 11 and 12 are respec-. tlvely side and'frontelevations, on a larger scale, of one of the stationary guide blades or members.

The side frames 2, the reed 3 and the lay 1 carried on. swords 5 on the rockin shaft 6 and actuated from the crank shaft? by connecting arms (not-shown), the tappet shaft 8. the supporting plate 9, the take-up roller 10 provided with the usual pins and the takeup roller 12 for the piece, and the cutters 13 are of ordinary construction.

The figuring-warp ends a and a are controlled by a figuring-harness comprisingcords b and actuated by suitable jacquard or other mechanism. The binder warp ends 0 and c and the stufi'er warp ends 6 are controlled respectively by heddles d and f in the usual manner. In Fig. 1 and also in Fig. 3 the acting figuring-warp end a is shown fully opened or. lifted higher than the ordinary binder warp end 0 The pile ends are shown as being operated from jacquard mechanism as is used for weaving a figured carpeting but when it is used to weave plain carpeting the pile ends may be controlled by a heddleor heddles operated by the ordinary harness levers in a dobby head, cams .or any other'of the various methodsiknown to those skilled in the art of weaving.

The pile forming wires 13 are arranged longitudinally of the fabric and extend rearwardly so as to more or less penetrate the spaces between stationary vertical guide blades or members 14 located immediately behind the ordinary reed 3 when such reed is in its extreme backward position, as

' ends of the longitudinal pile wire 13 which are each provided with a downwardly projecting end or hook 17 are loosely mounted between this cross-rail and a cross angleplate 18 detachably secured to the cross-rail 15. V

The upper and lower ends of the guide blades ormembers 1 1 aremou'nted in fixed spacing frames 19 extending across the loom and each comprising a backbar 21 and a front bar 20. The guide blades or members are separated the desired distance ap art, that is to say, the pitch of the pile wires is adjusted, by projecting pins 22 secured in each back bar 21, and thefblades or members are held inposition by the front bar .20 detachably" secured to the back bar. The said fixed spacing bars andtheir guide blades or members. form a kind of fixed reed. The'rear ends of the longitudinal pile forming wires are. adapted to. be moved laterally against the opposite sides of the guideblades-or members 1 1 of this fixed reed. f i

QMounted immediately in front or at the front edge of each guide blade for member 14 is a vertical guide wire 26 the upper por-,

tion of which is cranked or provided with a crank or deflector 27. These cranks are automatically operated fromprojecting arms 28 on the said wires 26 engaging with the dents of a reed 3O havinga transversely reciprocating movement and so arranged as to be capable of moving each crank later-- ally from its central or mid position i to.

either side of same and at the same time moving the free ends of the pile wires laterally. 1 Also mountedimmediately behind or at the rear edge'of eachguide blade or member 14 is preferably a wire slide 32 provided with thin sheet metalflanges 33 projecting infront of and embracing the guide blade ormemberand forming as a wholefa locking-slide '31. This locking-slide is' capable of being moved vertically up and down and is so arranged that when it isin its top or locking position the side flanges inclose a partly cut away or thin portion in the guide blade. -This thin portion is-preferably cut away and a thin flat wire 36substituted and loosely mounted'near the front edge; of the; guide blade in sockets formed in the'lto'p and bottom of the opening or notch formed in1 the guide blade. thin flatwire ormov able section 36 is adapted to move a little laterally when a pile wire is moved and pressed against sameby the crank of either adjacent guide blade causing the non-contacting. side of the pile wire to become flush or within the main portion of the guide blade thus insuring the pile wire being passed by and locked between .the side flanges of the locking-slide.

The sideflanges 83 of each locking-slide 31 are preferably connected together at the front edges by a connectingpiece 40 thus providing a flifterfor raising the wire vertically into its normal position.

The locking-slides are moved vertically up and down through the medium of a recessed cross-bar 12 into which recess the hooked ends43 of the slides project; The

cross bar ,42 is weighted bysuitable springs or weights i i 1 The reed 30 may be transversely reciprocated by a fle xibleconn ection or cord or chain A passing over and under guide pulleys a5 and l6frespectively connecting said reed to the lever 417 operated by the suitable cam or tappet 48,011 the shaft 8.

reed is returned ormovedin the opposite direction by areturning spring or a hanging weight connected to the reed by the cord 50. V Suit-able stops are provided fo limiting the movement of thjejreed. j i The weighted bar 12 for moving the locking-slides 31 up and do wn'is connected by cords orchains 52 ,to' the endsfofcranked levers 53 coupled together by the eonnecting red 541, one of'the'levers being provided with an arm 55 to which a cord .56'is at tached. the cord passing under the guide pulley 57 and connected at its other end to th lever 58" operatfld by the suitable cam.
