6 Claims.

The present invention relates to a direct warping mechanism and more particularly to a mechanism whereby a series of threads may be wound in courses longitudinally upon a warp beam di- 5. rectly from a series of cones, the rotation of the beam being controlled by an automatic stop mechanism actuated by the tension of the thread.

In the methods of win-ding a series of warp threads upon a beam used heretofore, the threads were wound from spools upon a mill and thence upon the beam. In both of these operations, one operator could watch only a small and circumscribed number of threads and the speed of winding was regulated at a low rate determined by the amount of thread upon the spools, the type of thread, and the expedition with which the winding mechanism could be stopped. In such methods of winding, if high winding speeds were used, threads would run loose or would be lost with subsequent difliculties in the knitting and dying operations.

The present invention permits of a direct winding of threads from cones to a beam; permits of thread speeds or winding speeds in excess of that permissible in the warp Winding operations heretofore used; provides a mechanism whereby rotation of the beam may be quickly and positively stopped; provides a direct beam winding mechanism controlled by automatic means; provides a mechanism for suddenly and abruptly stopping the rotation of the beam preventing threads from running loose and eliminating the possibility of lost thread ends; provides a stopping mechanism for the beam which permits of warp winding speeds far in excess of those currently in use; provides a mechanism for winding a warp upon a beam whereby the tension of the individual threads is maintained at 40 a substantially constant figure; provides a mechanism whereby a plurality of sections of a warp be wound simultaneously with the production of a beam carrying a series of warp M threads possessing substantially the same tension.

The invention further provides an automaticaily controlled direct warp winding mechanism which is substantially more economical in opn than the methods currently in use since ad speeds are substantially twice those can be used in other methods of winding ace the method permits of the supervision ,1 a greater number of threads by a given number of operators than has been possible heretofore, the method of winding a warp beam as disclosed in the present invention producing a completed warp beam in about one third of the time required for the usual mill winding operation.

Referring more particularly to the drawings, creel i5 is shown in Fig. 1 having front frame portions l6, longitudinally extending portions l1 carrying spindles l8 upon which are mounted spools IQ of thread 20. Creel i5 is provided with 55 outer rail portions 2| placed adjacent the spools so that thread from the spools is led through an eyelet 22 in rail 2| in contact with and between tensioning discs 23 mounted upon side rail 2| by any convenient means, as for instance by means of the bolt and nut 25 and 26 and provided with a smooth operating surface such as the porcelain sleeve 24.

Creel E5 is provided with an eyelet bar 21 extending laterally from side rails 2| and adapted to receive threads 20 from the several spools passing through eyelets 22 in' the side rails. Eyelet bar 2'! is provided with a plurality of eyelets 28 sufficient in number to accommodate the individual threads from a given row of spools, as for instance twenty-one eyelets, to accommodate the threads from that number of spools carried upon one row of a standardsize creel. In the form shown in Fig. 5, the eyelet bar is bolted to side rail 2| at the front ofrthe creel and extends outwardly and horizontally from the side rails of the creel, the creel being provided with an eyelet bar for each series of spindles or side rails. Threads 2!) are passed from the eyelet bar to the beam and are wound thereupon in a manner to-behereafter described. I

Averticallyextending supporting member 29 is spaced from the side rails 2| oi the creel and extends vertically thereof having attached thereto" an electrode bar 30 positioned adjacent but spaced from the eyelet bar at a point below the eyelet bar for a purpose which will become apparent. An electrode bar is provided for each eyelet bar and course of spools.

The electrode bar so comprises an outer U- shaped member 3| formed of electrically conducting material and having placed therein an electrically conducting member 32 between the legs of the U-shaped member and insulated therefrom by means of the. insulated material 33 The. u-shaped member 3t and strip member 32 form opposite ends or open electrical circuit, which circuit when closed actuates a stopping mechanism for preventing further rotation of the warping machine carrying the beam as will be described hereafter.

Drop wires or heddles'35 are carried upon electrode, bars 30,. each bar being; provided with a number of drop wires sumcient to carry all the threads from the number of spools upon a given series, as for instance twenty-one spools as mentioned above, for a normal sized creel. The thread fromthe spool adjacent the front end of the creel, as shown in Fig. 3, is normally passed through the eyelet adjacent side 2| while the thread from the next adjacent spool is passed through'the next adjacent eyelet and so on until all the threads from. all. the spools in the various courses have been arranged. Interposed between the eyelets 22 in the side rails and the eyelets 28 in the; eyelet bar are the heddles 35, the threads 25 being passed. through theelectrically non-conducting threading member 31, or eyelets 3. detachably attached to the upper portion of the drop wire, the lower'electrically conducting portion 58- being slotted to slide over the electrode bar 35, as shown in Fig. 5. Threads 2c pass from eyelet bar 21 to the beam and are wound to a sufiicient tension, to raise drop wires or heddles 35 to a height where no contact is had between the electrically conductingstrip member 32 and the upper edge- 39' of the slotted portion of the electricallyconducting portion 38 of the drop wire. Since all of the threads carry and support a drop wire thereon, each thread,

as it is wound upon the beam is wound under substantially the same tension thereby permitting the formation of a beam of threads in desirable condition for use in the preparation of a warp fabric since loose or lost ends are dimin- 5 ished and difficulties in dyeing from the production of various shades in the fabric due to difference in tension of the threads on the beam, is substantially eliminated.

It will be seen that upon the slackening ten- 0 sion of the threads, or upon breakage thereof, a drop wire 35, slidably positioned over the electrode bar 30 will be pulled downwardly by the force of gravity and make electrical contact between the upper edge of strip member 32 and the 15 upper edge 39 defining the slotted portion of the drop wire. This contact closes an electrical circuit which actuates a positive stopping mechanism attached to the beam as described more in detail hereinafter. 20

The warping machine, Figs. 2, 6 and '7, comprisesv a supporting frame 45 having a front rail 46, upright beam supporting members 41 carried by frame 45 for receiving and bearing a beam 48 adapted to be actuated by means of the 25 motor 49, and appropriate power transmitting means for communicating power from the motor to the beam. The beam is divided into a plurality of sections of which one or more may be wound simultaneously by employing an appro- 30 priate number of spools or creels.

A sliding bracket member 50 (Figs. 6, 7 and 8), adapted to be clamped to the front rail 46 by means of turn screws 52 carries the outwardly extending supporting member 5|, attached to 35 the clamping bracket 50 for supporting leaders, counters and the like, the whole bracket and support member being movable to any desired position along the beam.

A. vertically adjustable clamping member 53 extends upwardly from the support member 5| and is provided with a clamping member 54 at its upper portion for clamping and carrying the perforated leader or brass 55 through which the various threads being laid upon the warp beam are passed to position the threads upon the beam.

- A, guide support. 56 is adjustably mounted upon supporting member 5| and extends upwardly therefrom carrying upon its upper end guide bar 57, a bracket. 58 being attached to guide support 56 for carrying and supporting the forward tension bar 59 and the rear tension bar 60. Another supporting member 6| is attached to member 5| for carrying a. counting mechanism shown generally at 62. In operation threads 2|]. pass through the perforated leaders 55 over the forward tensioning bar 59 through the guide bar 51 and under the rearward bar 60 and from thence to beam 48 upon which, the threads are wound in 60 side by side relation to form a warp beam. The counter 62 for determining the yardage or amount of thread wound upon the beam, is of the genoral: or usual type and is actuated by the rotation of the guide wheel member 65 over which a 65 thread is carried in loop formv whereby the wheel is turned as a pulley for actuating counter 62.

A finishing table 66 is carried by the. supporting bar 61 for clamping and retaining the ends of the threads upon completion of the winding of 70 the warp beam. The finishing table is adjustably clamped to supporting member 5| and may be raised or lowered in height with respect thereto so as not to interfere with the warping operation and be moved upwardly to the thread line 68 Cir i is

at those periods when it is desired to use the table for holding and retaining the ends of the warp thread.

Table 66 comprises a horizontally extending member 59 of sufficient length to extend longitudinally of a complete section of the machine and is provided with a flat table surface adapted to engage a similar flat surface upon the companion table piece it hingedly attached to the horizontally extending table portion 69 at II, the upwardly extending portion I being adapted for pressure upon the horizontally extending portion 69 when lowered therein. A liquid container I3 is attached to the supporting member 5| and is provided with an outwardly extending bracket I -l carrying a reel I5 and a downwardly extending bracket I6 carrying another reel 11 which are provided with paper or other fabric carrying mucilage or paste upon one side thereof, the paste strips l8 and I9 passing from the reels I5 and TI between the guide spools I8, I9 attached to the upper portion of the tank, and over rotatable pulleys l8", l9" supported at the upper portion of the tank and having their lower portions immersed in a moistening liquid or fluid 82 contained in the tank and adapted to make the glue or mucilage attached to the under side of the strips responsive to pressure. Thus, when the threads are completely wound from the spools upon the beam, all the threads pass above the lower portion or leg 69 of table 66 and the glued tape or strip I9 is spread upon the lower leg of the table with the moistened glued portion upward. The whole table is then moved upwardly so that the threads are in contact with the moistened or gummed portion of the strip. Strip I8, from the other reel I5 is guided upon the upwardly extending leg I0 of the table in such fashion that the moistened gummed portion of the plate is exposed and when the strip and leg '89 are moved downwardly contact with the horizontally extending portion 69 is had on all of the thread ends passing over the lower leg 69 whereby the tapes or strips I8 and I9 retain all of the threads between the gummed portions thereof of the tape and hold the threads tightly so that none of the threads run loose or are lost in the process and the beam may be moved and used in the usual warp knitting machine.

The warping machine (Figs. 6, '7, l0 and 11) is provided with a hand rod 80 which is supported upon front rail 45 of the machine by means of brackets 9|. The hand rail is movable longitudinally of the brackets and makes engagement with the actuating lever 83 attached at its lower end 84 to a rotatable shaft end 85 extending laterally of the warping machine and supported in the brackets 86. Thus, movement of hand rod 80 toward the right or front of the machine produces clockwise rotation in the shaft 85. A link 8'! is attached to shaft 85 and has operative connection with the belt moving mechanism or lever 38 centrally thereof, the belt lever being pivotally attached at its lower end 89 and being provided with the belt guide and shifter 90 at its upper end which retains and guides belt 9| extending from pulley 92 of motor 49 to pulley 93 attached to the beam actuating shaft 94. Thus, upon movement of hand rod 90 to the left as seen in Fig. 6 and to the right as seen in Fig. toward the rear end of the machine, actuating lever 83 .causes rotation of shaft 85 in a counter-clockwise direction producing movement of the belt guide 98 thereby moving belt SI from idler pulley 95 to the operating pulley 93.

Actuating shaft 85 is also provided with an additional link mechanism composed of lever 91 extending outwardly from the shaft and the upwardly extending link 98 to which link 99 is attached. Link 99 is anchored to rod I00 rotatably supported in bracket I04, the rod having attached thereto one end of the braking mechanism IOI by means of the arm I02, the brake I9I extending over pulley I03 attached to shaft 94, the other end of the brake being anchoredon the pin I05. Upon movement of the hand rod to the right as in Fig. '7, that is, toward the front end of the machine, movement of shaft 85 is induced in a clockwise (counter-clockwise in Fig. 10) direction as noted from the front of the machine thereby causing movement of the belt guide 88, Fig. 10, to the left thereby moving belt 9| from actuating pulley 93 to the idler pulley 95, that is, to the phantom position, Fig. 10, while at the same time counter-clockwise movement of the rod I99 (Fig. 11) to which one end of brake IN is attached through the lever arm I02 is induced thereby causing an immediate tightening of the brake band and stopping the rotation of the beam actuating shaft 94 and beam 48 within substantially one rotation thereof thus preventing lost threads or threads running loose on the beam.

In order to induce automatic stopping of the machine switch rod I07, Fig. '7, is provided extending longitudinally of the machine and slidrail in brackets I08 attached to front rail 46,

one end of the rod being attached to spring I09, the other end of the spring being anchored upon a convenient portion of the frame, as by means of stud III], so that during the operation of the warping machine spring I09 is under tension and tends to move switch rod I01 to the right, that is, toward the front end of the machine.

{l solenoid I I2 (Figs. 7 and 12) is attached adjacent the lower portion of front rail 46 provided with a retractible latch member H3 (Fig. 12), urged to the protruding position by means of a resilient member or spring I I4, one end I I5 of the spring being attached to the casing H6 of the solenoid while the other end of the spring is attached to the latch member H3 at III. Collar H9 attached to switch rail I0? is provided with detent I I9 for engagement with the latch member H3 so that during such engagement the switch rod I0! is maintained in the limit of its movement toward the rear end of the machine, that is, toward the left as shown in Fig. '7. By energizing solenoid II2 latch member H3 is retracted into the solenoid permitting automatic movement of switch rod I0'I toward the front end of the machine due tothe urge of tensioned spring I09. In order to effect automatic operation of the machine collar 520 is attached to hand rod 80 and is provided with a downwardly extending fork I2I for engagement with collar l I9 upon the switch rod so that movement of the switch rod toward the front end of the machine automatically actuates the hand rod, causing movement thereof toward the front end of the machine thus moving the operating belt 9I to the idler pulley 95 and at the same time producing braking action in the brake I0! as heretofore described.

When in the operative position, as shown in Fig. 7, a collar I24, attached to hand rod 80, makes electrical contact with an electrically conducting spring member I (Fig. 12) attached to an insulated plate I26 mounted upon front rail 46.

Thus, in Fig. 13 electrical attachment is made from a source of current I30 to the resilient spring member I25 through suitable conducting means I3I, which in turn by means of contact with collar I24 produces a ground in the front rail 46 and frame of the warping machine. One side of solenoid H2 is grounded to the machine through the line I32 and the other side of the solenoid makes electrical contact with conducting member 32 of the electrode bar through the line I33, while the other side of the power line I34 makes electrical contact with the conducting U-shaped member 3| of the electrode bar 30. It is thus seen that upon decrease in tension of any thread permitting a drop wire 35 to make electrical contact with the electrode bar 30, closed circuit is produced energizing the solenoid I I2 producing retraction of latch member I I3. Upon escapement of detent I I9 automatic movement of the switch bar III! toward the front end of the machine is induced by spring I09 which movement in turn produces automatic movement of hand rod 80. However, movement of hand rod toward the front end of the machine causes disengagement of collar I24 with the electrically conducting spring member I25 which in turn causes the circuit to be opened, deenergizing solenoid H2 and permitting protrusion of latch H3. Upon clearing up any broken thread or taking up the slack and increasing the tension in any loose thread any drop Wire contacting with both sides of electrode bar 30 is raised from contact therewith and movement of hand rod and switch rod to the left will again cause engagement of latch I I3 and detent I I9 and the maintenance of these rods in a position where operation of the warping machine may occur.

It will thus be seen that the present invention provides a device for automatically stopping a warping machine in a short period of time without the danger of losing threads or of thread ends running loose and provides a mechanism in which a warp beam may be produced directly from spools without the usual mill winding.
