NARROW-WARE LooM SPECIFICATION formingart of Letters-Patent No. 734,390, dated July 21, 1903. Application fiiaa October 1'e ,1'9o1 'se itinojvasvi. (No man.)

To all whom it ntctyooncei t: 1

Be it known that I, FREDERICK EWALD ZEN- GERL, a citizen of the UnitedStates, residingin Philadelphia, Pennsylvania, have invented certain Improvements inNarrow-Ware; Looms, of which the following is a specification.

My invention relates to looms for weaving carpet and other fringes, familiarly known'as narrow-ware looms, in which bobbin-holding shuttles carried by a race-bar in the swinging lay are shot through the warpthreads to lay fringe ends therein and form the heading.

The object of my invention is to dispense. with the bobbins carried by the shuttles and in lieu thereof to provide the shuttle-bodies with a pair of nippers or clamping jaws adapted to carry the yarn from'a stationary cop to the warp-threads, so as to be woven therewith to form the fringe.

My invention also includes means for severing the weft-thread at regular intervals in order to form fringe ends of uniform length.

My invention is fully illustrated in the accompanying drawings, in which- Figure 1 is a plan view of sufficient of a loom to which my improvements have been applied to illustrate my invention. Fig. 2 is a similar plan view showing the operating parts in another position. Fig. 3 is. asectional view taken on the line Ct a, Fig; 1; and

Figs-4 and 5 are similar sectionahviews taken? on the line b b, Fig. 2, showing the partsiof the loom in different positions. i Heretofore in weaving fringe .inqlooms of this character it has been the common-pram tice to provide each shuttle with a bobbin, such bobbin carrying the weft-thread to form the fringe. These bobbins are so small, however, that they must be renewed many times during the day, entailing a considerable loss of'time, with a consequent increase in the cost of manufacture. r i

Theobject of my invention is to dispense with such bobbin andto employ the shuttlebodyusually carrying-the same as a carrier to introducethe weft-thread to the warps to form the fringe ends, such Weft-thread being mined intervals.

taken from a stationary cop of large size,

' whichmay be carried by the loom at any suitable point.

My'inv'ention is particularly applicable to 'loom's of this character weaving fringe consisting of a heading and fringe ends proper, and for the purpose of forming these latter of uniform length means must be provided for severing the weft-threads at predeter- In looms ordinarily constructed for the purpose of making fringe of this characterthe thread as itis woven into the heading is carried back and forth over a bar, and as the completed fringe is taken up by the usual collecting-roll a pivoted knife- 'blade is operated in connection with said bar, cutting the weft-threads looped over the same, and thus forming the fringe. disposed'that at all times there are a sufficient number of weft-loops over the bar to prevent any-pull or strain upon the weft-thread that This knife is so is being woven into the heading during the cutting operation. With the structure forming the subject of my invention, however, the weft-th read is cut at predetermined intervals after it is woven into the heading in order that a fringe of uniform length may be made, the portion out representing two endsof the fringe, such portion having been doubled at the solvage of the fringe-heading. This cutting is effected by-means of a pair of scissors having one blade fixed to the breast-beam of the loom and the other blade pivoted to the fixed blade and operated by suitable cam or other member .on moving part of the operating. mechanism. The movable blade of the scissors is supported in its raised position by means of a suitable spring, and 1ts end jto which the springis attached is also connected with the cam by a cord, so that it may. be positively operated at the proper time. The movement'of this cam or other member to effect a pull upon the cord is timed so as to be coincident with the movement of the lay when beating-up. an,d:takes place after the Weft-thread'has been engaged by the nippers of the thread-carrienfThis cam may operate a suitable trip or latchcontrolling a spring or. weight, such trip onlatch to be released by said cam immediatelyafter the thread has been engaged by the nippers of the carrier, or it may control any other suitable mechanism to effect a pull upon the cord at the proper time. I

In the accompanying drawings, 1 represents the movable lay carrying the reed 2 and the bars 3. and 4, between which the sh uttle'raceis formed. The race-bar is shown at 5, operating the pinions 6, which in turn drive the carrier 7 in the race. The carrier is provided with a pair of nippers comprising upper and lower jaws S and 9, the lowerjaw being fixed to the carrier, while the upper jaw is pivoted to the lower jaw at 10 and is maintained in the lowered or closed position by means of a spring 11, such spring engaging a pin 12, carried by said upper jaw and having its opposite end in engagement with the carrier. The spring is arranged at one side of the nippers, so that it will not interfere with the finger serving to open thejaws of the same.

The breast-beam 13 ot' the loom carries an arm 14, suitably fixed thereto and having at its outer end a movable finger 15, hinged at 16 and maintained in a horizontal position by means of a spring 17, secured at 18 to the arm 14. \Vhen the carrieris in the position shown in Fig. 4;, the projection 19 of the upper jaw 8 of the nippers is engaged by said finger as the lay moves to beat up, whereby the nippers may be opened to receive the Weftthread w, carried by \he cop 20, at a point between the portion already woven into the fringe-heading and said cop. The cop 20 is carried by the breast-beam, as shown. As the nippers open the lay continues its movement toward the breast-beam and the finger raises and passes over the projection 19, releasing the upper nipper 8 and permitting the same to close upon the weft-thread. The thread will be firmly retained by the nippers, and as soon as the lay finishes its inward movement to beat up the cord controlling the moving scissors-blade is pulled and the thread is out. These scissors are mounted adjacent to the arm 14: and consist of the member 21, secured to the breast-beam in any suitable manner and carrying the lower fixed blade 22 of the scissors, and the member 23, pivoted to the member and carrying the upper movable blade 24. The upper blade is maintained in an open position by means of a spring 25, secured at 26 to one end of said member 22 and at 27 to the breast-beam. At the moment the lay begins its rearward movement the scissors are operated, and this action is effected by a pull of the cord 28, such pull being accomplished by the aid of a cam controlling a suitable spring or weight to which the cord is connected, the cam being carried by a moving part of the mechanism for operating the 100111. The weftthread having been cut, forming the fringe end, the carrier 7, having previously engaged the weft-thread, is in position to carry the same forward to the warps, so that it may be woven in the heading, and

said carrier is immediately moved in the shuttle-race to effect this operation. It will be understood that the end of the weft-thread is retained by the nippers during the movement of the carrier in both directions, so that the thread carried by the same makes two fringe ends. In the'drawings herewith the fringe being Woven is shown, in which 29 represents the heading, and 30 the fringe ends proper. This fringe is passed as fast as woven over the bar 31 and is collected by a suitable roll or drum below the same, which may be driven by any suitable means. of fringe directly adjacent to the free weftthreads at the point where the Weaving operation takes place is immediately under the guard-wire 32, against which the reed strikes when beating up. This insures a uniform tension to the fringe and prevents distortion of the weft-threads, which would be occasioned if the heating was directly against the portion of the fringe-heading already woven. The finger 15 is so hinged to the arm 14 that when the nippers are moved away from engagement with the same such hinged finger will readily rise to permit such disengagement. The thread a: from the cop 20 is preferably fed through an eye 33, so that it will be in position for engagement by the nippers as soon as the latter are opened by the finger 15.

The operation is as follows: The carrier 7, with a thread in its nippers, moves through the warp-threads, which are shedded immediately after the passage of the carrier, and then the lay moves forward to beat. up the weft-thread engaged by said warps. As the lay moves back the carrier is again passed through the warp-threads, laying therein the free end of the weft-thread, and as the carrier continues its movement this thread pulls out of the nippers. As the lay moves forward to beat this last thread up the nippers will be opened to again engage the weftthread, and immediately after this engage ment the said thread will be out between the portion first woven into the heading and the part engaged by the nippers. The cuts being made at the same point and the movement of the carrier being properly gaged, the fringe ends will be of equal length, the portion of the thread carried by the nippers to and fro forming two fringe ends.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. In a loom of the character described, the combination of the movable lay, and a threadcarrying member reciprocable in said lay,

said member being movable in a straight line and having jaws at right angles to its line of movement to engage and carry a weft-thread in both directions through the warp-threads to form the fringe-heading, such thread also forming two fringe ends, substantially as described.
