Application filed December 17-, 1-924. Serial No. 756,441.

To (ZZZ whom it may concern v Be it known that I, TILLIAM J. Ln'r'roN, a citizen of the United States, and resident of Paterson, in tl e county of Passaic and State of New Jerse have invented a new and useful improvement in Looms, of which the following is -a specification.

This invention relates to an improvement in looms, in which plaits of any desired width may be woven at predetermined (llS tances apart into a fabric during the continuous weaving thereof. I

My invention further consists in providing mechanism for producing the above results which will be very, simple, effective and which will not interfere in the regular action of the heddles-and lay beam 01"" the loom.

My present invention more particularly contemplates certain improvements n looms of the type shown, described and claimed i-n my United States Patent No. 628,206, with the object in view of improving the means tor controllingthe movement of the woven fabric on the winding beam.

A practical embodiment of my invention is represented in the accompanying drawings, in which' Fig. 1 represents a front elevation of: a loom having my improvements applied thereto.

Fig. 3 represents a vertical section taken in the plane of the line III- 111 of Fig; 1, look" in the direction of the arrows.

Fig. 4 represents a detail vertical section of the winding means and adjacent mechanism for the woven fabrigand I 5 re resentjs diagranimatically four detail views of the fabric, showing the several stages during the weaving-got the plait side elevation of the therein.

The heddles 6, 7, 8 and 9 are all utilized for weaving the ground or body of the fabric, while the heddles 6 and 7 alone are used for weaving the loops which are to form the plaits. Then the hcddles 6, and 7 are being actuated .to form the loops the hjeddles 8 and 9 remain stationary.

An auxiliary frame 10 is attached to the rear of the main frame 1 andarranged to receive the journals of warp beams 11 and 12. These warp beams 11 and 12 supply the warp, threads to the severalheddles. The warp beam 11 is provided with the usual weighted frictional device, which consists of a flexible strip 13 passing over a pulley let on the warp beam and provided at its dependent ends with a large weight and a smaller weight 16. The function of the weight 15, is to wind the warp threads onto the beam 11 thereby tending to exert the tension on the thread leadingflto the heddles Sand 9 rearwardly. The warp beam 12 is also provided with a frictional device which comprises a flexible connection 17 arranged to connect a pulley 18 on the beam and having one end. secured to the floor at 19, while the other end has secured thereto a weight 20. The threads from the warp beam 11 are directed overa guide roller 21 mounted in brackets carried by the auxiliary'frame 10.

The winding beam 23 upon which the woven fabric is wound is mounted to rotate in supports 2-1, 25. secured between the breast beam 26 [and a gift 2?, which breast beam and girt are fi'vedin the main frame 1. An intermediate winding roll 28, also carried by t supports 2i and 25, is provided with ',....i 11. 11 sna e v for engaging the fabric and prev- 'ting 'it fromislipping ther therabrieiswooed orunwbuiid. Idler Ollers 29, 80, are me ntejd in the supports, 24, in close proximity to the winding roll 28 so asto cause the tiabricto engage a censiderahle pojr on of tlie periphery of the (ill The pinion 32 and spur gear 33 are loosely mounted on a stud fixed to the support 25.

Rotary movement is imparted to the winding beam 23 and winding roll 28 in a direction to wind the finished fabric by means of a ratchet wheel 36 mounted on a stud 37 and provided with a pinion 88 which meshes with the spur gear A pawl 39 is arranged to engage the ratchet wheel 36 and is lived to a lever 40, which is connected by a link l-l to an arm 42' fast on the one end by a shaft l3 journaled in the main frame 1. The link it is cmineeted at one end of the lever near he pawl, while the other end projects rearwardly and pivoted at all to tho oscillatinearm 4-?) pivoted to the frame at -16. The lower end of the oscillating arm 45 is adjustably connected to the lay beam 2 by means of a bolt i7 which is arranged to ena slot l8 in the lay beam and a slot 49 in the oscillating arm it). Thus it will be seen that by reason of this bolt and slot connection between the oscillating arm to and lay beam 2, a proper movement may be given the pawl 33!) and the rotation of the ratchet wheel 3 governed accordingly. The rocking movement of the lay beam 2 will impart a uniform moven'ient to the pawl -39 and ratchet wheel 36. which in turn actuates the winding beam 223 through the pinion 38, spur rear 33 and pinion 31- fast on the winding; beam 23. while the winding; roll 28, at the same time. receives its motion through the pinion 32, fast on the spur gear 33 meshing with the spur gear 31 fi ed on the roll. The pawl 51!) is lifted out of engagement with the ratchet wheel 36. when desired. by means includinp; an arm 50. secured to the other end of the shaft l3. which arm connected by a. link bell crank levers 51. 52 having links 5-). o-l, which link 54: is "ecured to one end of the usual angle lever 5. the move ment of which is controlled by tubes and rolls (not saown) on the pattern chain 56. Tu conjunction with the pawl 30 a spring; actuated pawl 57, pivoted to the main frame 1 at 58, is arranged to engage the ratchet wheel 36 and hold the same against unintentional movement. The pawl 57 is rocked out of en eagement with the ratchet wheel. 36 by means of a linlc 5!) which conne 'ts the lever it) with a tail ll on the pawl ST. A flexible connec tion (ll leads from the other end of the an- 'le lever :1) an and suitable idler pulleys lit to one end of a bell cra .h lever (t l: pivoted to the main frame 1 at ($5. The other end ol the bell. crank lever is provided with a tlesible connection (36 which is guided in a pulley 6T adiustably mounted in a bracket 63 carried by the auxiliary frame i 7 weight 65) is attached to the end of the flexibie connection 6-6 to apply a yielding ten sion to the parts connected therewith:

"The arrangement of the pattern chain such that all of the heddles and their warp threads are used for weavingthe body of the fabric between the plaits and only the heddles 6 and 7 and their warp threads are used for weaving the strip which is to form the plait, while the heddles S and 9 are helo motionless.

he means employed for permitting' the woven fabric to be drawn rearward'y at predetermined intervals for allowing; the lay beam 2 to beat up the portion of the fabric which has been woven to form the plait is as follows A second pawl Tl) is airanged to engage the ratchet wheel 36, which pawl is lived to a lever 71, pivoted at 72- to the end of an arm '73 havingits fulcrum at T on the main frame 1. This arm 75} is limited in its oscillatory movement by means of stops 75, To, arch of which is provided with a slot TT and a bolt 75, which bolt secures its stop to the main frame 1. The pawl 70 on the lever '71 yieldingly held in engagement with the ratchet wheel Si; by a spring T9 attached be tween a pin on the main frame 1 and the lever 71. The pawl T0 is lifted out of engagcment with the ratchet wheel 36 by means of a pin S1 projecting" laterally 'rom a melting lever 82. one end of which is fulcrumed at 83 on the main frame 1, while the other end is attached to the usual angle lever 9 l by a link The movement of the angle lever 5 is also controlled by tubes and rolls (not shown) on the pattern chain 56.

The operation of my invention is as lo we 2-- All of the heddles 6 to 9 inclusive are crating alternately to form the body of fabric beine woven. and as the loom is erated. the finished fabric is wound onto winding beam 23 in the manner hereinbcfore set forth. After a prcdeternlined amount of the body of the fabric has been woven the warp threads which lead from "he beam it are held stationary and the warp thrauls which lead from the beam 1 are being utilized to weave the portion o the fabric which is to form the plait. Who; the desired amount of fabric to form tie plait has been woven the winding mechani m released and the fabric will be drawn rearwardly until the lard shot of weft of the said plait is forced by the movement of the lay beam 2 into proximity to the first shot of weft of said plait. thereby forming a dependingloop. ll'hile this boa ing up process is in operation all of the beddles have been set in motion. and the wear-- ing of the body of the fabric is again l egun. is the plait portion is being' beaten up to form the plait. he r sh ts o." weft a e intrediu-ed into the iabric. so that when the plait is finally set up there will be a sufficient number of shots of weft woven into the fabric to :eeureh. locl-t'the plait,

fill

01)- the opthe 84, which levers are connected with the winding 'lQCllfiHiSll] as has herebelore been set forth. The train of gear wheels of the winding mechanism is actuated by the oscillation or the lay beam 2 and the arm which moves the lever l0 and with it the pawl 39, which in turn rotates the rat het wheel 36 and the several gears in the train. This movement of the ratchet wheel 36 also carries the pawl with its lever "71 and arm 73 rearwardly until the arm 73 rests against the stop 76. At this time, the pattern chain 56 will have been brought into position to actuate the angle lever 55, which mo ement, through the links 54, 53, bell crank levers 51, 52 linl; 50* and arm 50, will rock the shaft 43 with its arm l2, which inturn moves the lever e0 by the linl: 431 so as to lift the pawl 39 out of engagement with the ratchet wheel Simultm neo'usly with the. movement out the lever ll), through the link 59, the pawl 57 will be thrown out of engagement with the ratchet wheel 36. When the ratchet wheel 36 is released of the pawls 39, 57, it will be free to move in a reverse direction and ermit the wovenfabric on the winding beam and roll to be drawn rearwardly by the tension of the weight 15 on the warp beam 11. This movement of the ratchet wheel 36 will also 'carry the pawl *ZO, lever 71 and arm 73 rearwardly until the arm 73 trikes the stop 75 and arreststhe movement of the ratchet wheel, inwhich position the pawls 89 and 57 will be brought into engagement with the ratchet wheel 86. The angle lever 8% is now actuated by the chain 56 and the lever rocl-red through the link 85,. This movement oi? the lever 82 brings the pin 81 in engagement with the lever 71 which is lifted so that the pawl 70 is disengaged trom the ratchet wheel 36, after which the angle lever Se is returned to its normal position and the pawl 70 caused to assume its engagement with the ratchet wheel 36. In this position, the arm 73 is substantially in contact with the stop 75, and as the fabric is woven and wound upon the winding beam by the movement or the lay beam 2, arm 45, pawl 39, ratchet 36 and the adjacent mechanism, the arm 73 by reason of the 'pawl 0 ei'igaging the ratchet wheel and lever 71 will be gradually carried rearwardly until it isarr'ested by the stop '76, at

v which time, the pattern chain 56 will again actuate the angle lever 55 and the sequence of operations by the various parts repeated.

By reason of the mechanism above described, I am enabled to weave plaits of varying width into the fabric during the continuous operation of the loom, and also weave plaits at various distances apart to suit dilterent requirements.

The mechanism for inserting the weft in the if er'ic has been omitted from the drawings and description, since it would tend to unduly complicate the structure. Any suitable weft introducing means may be employed, as the structure which I have shown and described for weaving plaits into the fabric not interfere with the weft introducing means.
