WARPING MACHINE.

Application filed June 25, 1923. Serial No. 647,466.

improved means for stopping the rotationl ofthe beam when a thread of the warp breaks or becomes unduly slack; the 'mechanism as constructed for the "accom- Cplishing of this object includes a series `of etectors or fallers respectively `engaged 'with and controlled bythe threads of the warp, and a further object of the inventionl is to provide for the detectors being used to `produce a cr0ssvinthe warp, as in warping, i. e., an arrangement of the warp threads in which the alternates will be separated from the remainder. l

A warping machine isshown of. the type]A illustrated in vmy Patent No. 1,377,751, lbut it will be understood that the invention may be applied to Aother warping machines or in fact to any machine in which a warp isv A lever Z is fulcrumed at e `in the frame and in this lever is journaledone end of a shaft f on which is fixed a lwheel gadapted to rest on the groo'ved periphery of and be driven by the wheel c, the` shaft having thereon a member z, on which to wind the warp fixed in some way to rotatetherewith- The beam is here taken as comprising the structure f gv h.

' tion of the beam; In the present case there vthe support fand when the lever isv turned tectors and associated parts and the struc-k On the frame may be-journaled the drum a over which the warp extends, being held in peripheral contact therewith by the rollers a2; c3 is the usual condensing reed.

yMeans `is provided for stopping the rotais a support which Vis here in the form of a lever.' Anotherlever y', forming a cam device or chock, is fulcrumed on the shaft f and has one end'adapted to bear against clockwise it elevates the beam out of contact' with the (going) wheel so as to stop the rotation of the beam; The lever is f connected by a link 7c with another lever'Z fulcrumed at fm in theframe, and this lever has pivotally connected with it a hook memfbera which projects rearwardly yand may be confined` tojup and down movement on its pivot by a guide o on the frame.

y) is a rotary element gournaled 1n the frame on a horizontal axis and having ran eccentric pin which forms yan abutment.

`The hook member is arranged so that its free or hook end is arranged in the path of and adapted to be engaged and moved by the abutment g, such movement when it 0ccurs being to the right and thus adapted to shift thelever clockwise for stopping the rotationl of the beamf The element o is rotated from the `drive shaft b by a sprocket and chain connection r or in any other way. f

It'mayl be stated 'thatso longas all thef warp threads remain unbroken and not unduly slack the'hook member n is` elevated on each cycle ofthe element p outof the path of its abutment g, so as not to be caught byr the latter and stop the rotation of the beam. 'Ihe means for accomplishing this is as follows: Between the warping machine and a creelsof well known type which carries the revoluble spools t from whichvthe individual threads of the` warp are taken and which has .a` bar u overwhich and through a reed o the warps extends, and 100 which coact with the warping machine to maintain the threads of the warp taut as they are being ywound on the beam, is ar-` ranged a stand w' having attached thereto a head formed with ahorizont'al slot g/ 105 in the end of each of its arms rIn these slots slides abar .athesame being adapted 4to be reciprocated by the arms cfa rock.

Ydetectors to stay them.

ing member' 2 ulcrumed in an arm 3 which projects vfrom the stand w. connects a third arm ofthe rockin structure with the stand'w and acts to s ift the rocking structure and hence the bar e to the right in Fig, 1. Each movement in the direction indicated is made possible by moving the bar between these movements 1nV the opposite direction, and this is accomplished by a {iexible connection 6 attached to the bar centrally thereof and extending back `overy a pulley 7 on frame c and attached'to the hoolr member a, which it may now be statedv is subject to the depressing action of a rotary cam 8 journaled in :trame a' and adapted to be driven from the drive shaft b by. 9 in synchronywith the element p. So long as the means zis'not prevented from performing-'its movements `to the-right it eleyates the hook'membe'rn 'out of the path of the'abutment g on each cycle of element p, but it itsmovement to the right is prevented the hook member remains depressed so thatit will 1be caught by the abutmentand so'stop therotation of the beam.

' Thea-means for preventing the movements l to 'the right of the means e6 when a thread breaks or becomes unduly slack will now be explained: Freely movable vertically in 1ndividual holes of bars 10 of a superstructure 171 carried' by the arms m of the head @c of the standard is a series of Jrallers or detectors 12, each havingl an'eye 12 penetrated by a thread ot warp A. The warp normally holds all the detectors in the positionshown in Fig. 2, so that their lower ends are above the plane of 'movementfof-the bar e, the-normal plane of'all the threads being indicated by the line show-n vsolid f in Fig'. 1. But I if a thread breaks or becomes unduly yslack the corresponding detector will fall into the path ot thebar e, thus to stop its' movement to the right. There may be an abutment `bar 13 to theV right of the vlower ends of the It will be understood that the means for effecting the movements of the hoolomember a out of the path of the abutment q, together withthe detectors", may be placed elsewhere than as'shown so long as the detectors are engaged with Vthe threads between the means for-'maintaining the warp taut. As herein illustrated this part ofthe mechanism takes the place andmakes unnecessary the useV of the usualcross.reed` by being constructed as followsz rflue detectors have lateral lugs 12"` and they are arranged so that the lugs ofthe alternate deteetoleeloieet oppeetely to these e'f'tbe remet-ndertbe superetrueture is.. fulernmed eperof rockers le eeebheVingeletS-leeto reeeve e horizontal met lwbehelieee elette/16 on theenperetr eterea'ene-seeb/rod being entitav eeeh meetings-1245 By menienletinae rocker A spring i` va sprocket and chain connectionA to elevate its rod the corresponding detectors can be raised, thus displacing their warp threads out of the planeA so that a shed or cross is formed by the latter and the remaining (or depressed) threads.

Havingk thus fully described my invention, what l claim as new and desire to secure by Letters Patent is 1. The combination, with a rotating beam on whichfto wind the warp and means coactive with the beam to normally maintain the threads of the-warp taut, of a rotaryelement havingv aneccentric abutment, means movable to stop the rotation of the vbeam and arranged in the path of and to be then engaged and moved by said abutment, means, movable in a given direction/von each cycle of said element, to move the lirstmeans out of said path, detectors each normally nrged into *position* to oppose movement offthe second means in eadfdreoton but llevllgv its movement into Suele position opposed by e tbreed'of the Wenn-enel.

of which at intervals in the row have lateral projections, said detectors being normally urged to move in one direction but being held against said movement by the taut Warp i threads, mechanism, cooperative with each detector upon movement thereof, for causing stopping of the rotation of said beam, and

up-and-down movable means adapted on movement in one direction to engage the several projections and thereby shift the corresponding detectors and thus the threads engaged thereby out of their normal positions.

In testimony whereof I affix my signature.
