Application filed July 2*?,

T0 all whom t may concer Be it known that I, JOHN lV, Soi-IN, a citizen'oif the United States, residing at Roxborough, countyof-Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Methods and Apparatus for Beaming Warp, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this speciication.

This invention relates to an improved method and apparatus forwinding warp beams, particularly binder Warp beams for pile fabric.

As is well known to the art, binder warp beams for weaving some fabric of this character contain in the neighborhood of i880 warp threads or ends; p

The obj ect of my invention is to provide a method of beaming such warp and a device for carrying out the method in which the human element is eliminated toa very great extent, so that I am enabled t0 provide a beam without broken ends as well as a beam in which each threadhas been wound under substantially the same tension in its proper position on the beam so that the length of all the ends is substantially the same.

In carrying out my invention for a beam having 4.880 ends, I provide anumber of beams, for example, four, each with 1220 ends, place these beams in parallelism onv suitable supports in which they are free to rotate. I then conduct the ends from two oi' the beams about tension members to a roll in front of a measuring device and interpose between some of the tension devices guiding reeds and an automatic stop device. This stop device is arranged to stop the machine ii any of the ends are broken or slack. The ends from the other two beams pass around and through similar devices to the roll in liront of the measuring device. The ends from the four beams then pass from said roll about a measuring drum and. around a roll beyond the measuring device, the two rolls together with the meas-V uring drum also forming `a tension device. The ends then pass from the last roll through a guiding reed which maintains the different ends in their prearranged positions to the beam on which they are wound.

The four beams from which the linal beam.

1921. Serial N0. 487,882.

is wound may be beamed. in any desired manner, but-I prefer `to beam them from separated threads each drawn froma separate source, and in their passage from the source to the beam I pass them around suitable tension devices so as to place anequal tension on each end as it passes to the beam. I also provide suitable stops `rer stepping the machine any of the ends are slack or broken.

Fig. l of the drawings is a side elevaf tion in diagram. of one form of apparatus for carrying out the lirst step of my process.

Fig. 2 s a similar View of an apparatus.

for carrying. out the final step` of winding a beam having large number of ends.

In Fig. l `et the drawings the reference character 5 designates the creel for supporting the required number oit' tubes 6 of yarnV end can readily be traced and spliced. vEach thread passes from its guides and stop on the .Creel through a guide eye on a board 7.

The various ends pass from the guide oye board 7 under the over guide rollers S and 9, and then through a separa-ting device l0, consisting oi a 4plurality of wire eyes similar to heddles,r in which alternate threads pass through the eyes while the others pass between the wires forming the eyes. Onehalt` of the ends then pass over a separating bar ll, while the other half passes under said bar. The ends then pass trom the bar 1l through a reed l2 and a supplemental.

.stop device 13', which are arranged to keep the various ends separated so that the stop 18, which controls Yelectrical devices, will stop the beamer if any of the ends are slack or broken, as hereinafter described.

14; is a guide roller over which the ends pass from the stop device 13, and 14. is a easuring drum about which the ends pass from the guide roller. 14 to a guide roller l5. 16 is a second separating bar below the guide roller l5, onefhal'f of the ends passing around one side thereof while the other halt passes about the other side'.` 17 is* a second reed between the bar 16 and the warp beam 18 on which the ends are, wound. B isa bearing, there being` one on each side of the machine for supporting` the warp beam 18; 19 is a tension device or press for the warp beam comprising a longitudinal bar,i which engages the ends or warp threads as they are wound on the beam, and which bar is carried by two weighted levers which are arranged te hold the bar againstthe wound warp withan equal pressure ,throughout the windingof the beam, by means of suspended weights. y

Y The machine isidriven by suitablemechanism hereinafter described to cause the ends to be vc rawn from the varioustubes 6, around and through the various lguides y'and separatingJ devices, as well as the electrically controlled stops, by the rotation ot the warp beam 18; -Th'e various guides are arranged to place the Xends undertension and also to i It frequently occurs that an lend breaks between the guides 'onV the 'Creel 'and some et'l Vthe guid'esbetween vthe Creel and the measuring drum, "and very 'frequently the end will be picked up 'by oneot the other endsV and drawn ahead, thereby be'tore the stop on the cre'elhas time to tall into vstopping-- position, and as the broken end continues to be vdrawn 'from the tube, the stop on the creel will fail to V- Y v By placing a supplementalstop device ad- `jacent tofthe 'measurinp., drum or near the point v',gi'reatest tension ofthe ends, I lam enabled 'te step the 'machine if any orr the ends break close to the beam, and thereby av'oidY broken ends ofthe beam,y as well as stop the machine 'if an `end'should bebrolren and pi'clredfup by 'another 'end' and carried lor'ward before t'liebreel stop acted.

l 1n the coiistr'uc'tion shown, the beam is' drivenby means 'of a pulley 20 connected to the beam many desired manner, which is'in turn driven from a pulleyQl by a belt 22.

23" 'is a fdriyiiig pulley dhithe shaft olf 'the pulley '21 driven by beltZlV irdin yanv suitable sofurc'e. The pulleyQB isarranged to IbeY connected vto the pulley 21 by means of a clutchQ'which is arranged to `be thrown by hand lto 'connect the lpulleys to each other and is re'tainedih 'driving relation by an electrically actuated latch 26. rfhis latch is ei'gy one pole oi' which is connected to a con- Vtension of the ends 34e-to Seidbetween fl f arranged to release the clutch to stop the machine when the latch magnet 2 is energized.

28 is a battery or source of electrical entact 29 on the stop 13. 30 are contacts one on each side of contact 29 which are inter connected and are V"connected to one pole or magnet 27. rlfhe other pole of the magnet is connected to the other pole ol" the battery. The stop 13 is provided with a plurality ot circuit closing' fingers 51 of the usual type,

i there being` one for each warp thread or end,

and are arranged `to separate the threads,

while the tension on the ends will hold the lingers out of engagement with contk cts and 3th 1t` one 'of the threads should become slaclr `or bro'lren, itscircuit closing,l linger will drop and close the circuit through the magnet 27,1eleasethe clutch 25 and stop the machine. The stops on the Creel each comprises a pivoted finger 32 having an eye through which the thread passes trom the tube or bobbin G to its eye inthe board "4"; The finger 32 is connected to one pole et the battery 28 and 33 is a contact connected to one pole of magnet 27, the arrangement infg such that when any ofthe threads brealz near the tube, its linger will drop, close the circuit through magnet 27, and stop the niachine. Y

The. second: step ot this process may be carried out byapparatus, such as shown in Fig. 2, in Awhich four beams such as beams 18,..wound en any apparatus such shown intFig. 1, eachhavingg, for example, L20 ends, .are Asupported inV parallel relation to ech other as fii'idica'ted atlSa, 18h, 18C and 18d in bearingsvlSG, 1Sf, 18gV and 13h respectively. The ends 34a and 34; beams 18a. and 18 respectively pass over guiding andten'sion roll 35, then through aneapansion reed fdgstop, around nuidinfljnand tensioning rolls 3S and 39, a measuring; drum 10, anotheriguiding andtensioning` roller 41 and a'second expansion reed 36d to the beam 12 `on which they are wound. rlhe ends 34s* and 34d Vfrom beams 18c and 1S 'pass over and throughy similar devices 35, 3G, 37 and to the roll 39, and from which roll the;v pass around and through the same derices to the 4beam 4211s the ends from the vb :t

As the ends trom the diiiier "i beams 18, 18h, lcand 18dV in their tothe beam 1-2, passaboutsimilar tension devices, the tension on the `tour sets ot e: from the beam ti'willbe suiistantially edu'i its the lengthot the different ends on bea-1 18a to 1Sd are substantially the saine,

"n, iL ci,

beams 18a to 1S?lv andthe :.first tension de willbe substantially Ythe saine, and as, same tension `is applied "toz `the if'arious e romthe diiierentbeams,the length as we as the tension ot each ot' the i880 ends en 130' bea-m 4t2 Wound by this -method will be suhstantially the saine. It desired., l may use a pressing' and tensioning device such as on the beam l2 during the winding thereof, which is similar to the devise ll) shown in Fig'. 1. y

The beam 42 is driven by a pulley which is in turn driven from a pulley 45 a belt lle, The pulley l5 is driven troin a pulley i7 which is in turn driven from any suitable source ol2 power and is arranged to be connected to, and disconnected treni, the pulley l5 by a clutch e8. 49 is a lever lor shitting' the clutch i8 into drivin` connecu tion and is arranged to be held in such shifted position by a latch 50. The latch 50 is arranged to be Withdrawn by a magnet 5l as hereinafter described to release the clutch lever, which will in turn shi'lt the clutch and disconnect the machine 'from its driving mechanism.

The stop 27 is provided. with two sets ot circuit lingers 52, there being` one :tor each end. These lingers are all alike, but are split up in sets as the end4 are too close to each other to permit placing', for example, 2440 fingers in alignment, so therefore l divide the .fingers into a plurality oi' sets. These lingers are arranged to close the circuitbetnfeen one or the other ot tivo eontact devices and a contact 54e. The contaots are connected to each other and one pole ot a battery 55 or other suitable source oli electrical energy, While the contact -l is connected to one pole olf the Winding): or" the magnet 5l, the other pole or the Winding' being connectedto the other pole oit' the battery The stop 37 is provided with similar fingers 52 and contacts 53"' and 549. ConH tacts 53 are connected to each other and the contacts 53, While contact 541, is connected to Contact 54.

By means el the above described connections, the circuit will be closed through the coil oit magnet :il il" any oil the ends should become slack or broken and permit its Finger to fall, which will stop the machine, and as soon as the end has been spliced and the slackremoved, the circuit will be broken by the lifting ot the fallen tinge/r, so that the machine can be again set into motion by shitting the clutch.

The advantages oit my invention result from the provision ot a method and apparatus lfor Winding beams having' a relatively large number oil ends or iva 'p threads in which substantially the same tension is applied to each end, so that all oil the ends on the beam ivill be ol substantially the same length and under the same tension.
