A bracket 56 (see Figs. 1, 2, 4 and 5) is swingably mounted on a stationary rod 58 carried by supporting elements 60 and held in its position by set screws 62. The supporting elements 60 are slidably arranged on rods 64 carried by stationary parts of the frame of the warper. The supporting elements 60 may be held in any adjusted position by means of set screws 66 (see Fig. 4). For the purpose of balancing the weight of the bracket 56 and the parts connected therewith in the intermediate positions of the bracket between'its operative upright position shown in Fig. 4 and its inoperative horizontal position shown in Fig. 5, two torsion springs 68 are wound around the rod 58, one end of each torsion spring being secured to therod, the other end of each torsion spring being secured to the bracket. The bracket may be held in its upright position by means of a locking screw swingably mounted on a stationaryV extension 12, which may be engaged with a complementary locking member 14 on the bracket.

A bearing 16 arranged on the bracket 56 carries the shaft 18 of an idling head 8|). The rotatable shaft 18 rests on rollers 82 of thebearing and is arranged With play in the bearing, i. e. the shaft may also be shifted in the direction of its longitudinal axis. One side of a thrust ball bearing 84 mounted on a shiftable rod 86 extending through a hole in a cover plate 88 of the bearing 16 is in contact with the end of the shaft Now, the insertion ofl an empty beam 44 into the warper shall be described: For this purpose the supporting elements 60 carrying the bracket 'I8 of the idling head. A spring 90 arranged between the plate 88 and the other side of the ball bearing 84 tends to urge the latter against the end -of the shaft 18. The idling head 80 and its shaft 'i8 may be shifted to a certain extent in the direction of the arrow A against the action of thel spring 90. 'I'he movement ofthe rod 86, ball bearing 84, shaft 18 and idling head 80 in the 'opposite direction under the action of the spring 90 is limited by a set collar 92 secured to the projecting end ofthe rod 86.

A gear 94 keyed to the shaft '|8 of the idling head meshes with a pinion 96 keyed to the shaft of a shut off counter 98 mounted on top of the 56 and the rods ||0 of the rest bars |00 are brought into a predetermined position in accordance with the width of the beam to be inserted. Of course, if the supporting elements 60 are already in the proper position, a-special adjustment thereof becomes superfluous. The bracket 56 is swung into the horizontal position shown in Fig. 5, whereupon the empty beam may be easily placed into the warper by sliding the flange |20 along the rest bars, until one end of the center hole |26 comes into engagement withthe driving head 50. The conical shape of the driving head facilitates the engagement and causes a slight lifting of the flange |20 away from the rest bars |00. During the engagementA of the driving head 50 with the center hole |26 of the beam, a key |30 arranged on the driving head is brought into engagement with the longitudinal notch |28 to establish a positive drive of the beam. YNow, the bracket 56 is swung into its upright position shown in Fig. 4, so that the idling head 80 comes into engagement with the other end of the center hole |26. The idling head is also of conical shape, so that the flange |22 of the beam is slightly lifted away from the rest bars |00 to secure a free rotation of thebeam. During the engagement of the idling head 80 with the center hole of the beam, th idling head maybe shifted to a certain extent in the direction of the arrow A (Fig. 4) against bearing 16. I'he shut off counter 9,8, which may be of any well known type, serves to cause an automatic stoppage of the warper as soon as the beam 44 has performed a predetermined numbelow the space occupied by a beam 44. Each resty bar comprises two members |02 and |04, which are adjustable with respect to each other by means of a slot and screw connection |06. The rest bars |00 are connected with rod |08 and ||0 at the ends thereof. The rod |08 is slidably and adjustably arranged in a bore of an arn |4|2 mounted on the frame of the warper.. Avset screw ||4 serves to hold the rod 08 in the adjnusted position. The rod I0 is slidably and adjustably arranged in a bore of an extension ||6 of the adjustable supporting element andis held in its position by a set screw H8. Thus, the

rest bars |00 may be adjusted in a certain positionA with respect to a beam 44 by means of the rod. I 08, ||0 and set screws ||4, H8, while the length of the rest bars may be adapted to the width of the beam used by means of the slotl and screw connection |06. Therefore, the warper may be used for beams of various sizes and shapes. 'i

Fig. 4indicatesk a beam 44 of usual form ,in

.other words, the above described play of the idling head and its shaft 18 allows for slight differences in the width of beams of a certain standard size. After'locking the bracket 50 in its upright position by means of the screw 10, the operation of the warper may be started.

In order to remove a. full beam from the warper after the termination of the warping operation, the bracket 56 is swung into the horizontal position shown in Fig. 5, whereby the idling head 00 4is disengaged from the center hole of the beam and the flange |22 of the beam drops onto the rest bars |00. Now, the operator has freevaccess to the flange |22 and may easily remove the beam from the warper by sliding its flange |20 along the'rest bars |00. j

According to Figs. 1, 2 and 3, a pressure roll |32'of a width somewhat smaller than the distance between the flanges |20 and |22 of the beam 44 rests against the winding |34 on the beam. `As best shown in Fig. 6, the pressure roll |32, which is selected in accordance with the standard size of the beam to be'inserted intothe warper, is exchangeably journalled in roller bearings |36 and |18 carried by arms |40 and:v |42 mounted on a rod |44 rotatably and shiftably arranged in bearings |46 and |48 of the/frame of the warper. The longitudinal axis ofthe rod |44v is substantially parallel to thelongitudin'al axis of the beam 44. 'I'he arm |40 is -xed to the rod |44 in anyv suitable manner, while th'e arm |42v is slidablyand adjustably arranged on the rod |44. so that the distance between the arm |40 pagina 3l Thema inieheliiiniispeei'senbymemsor asetscrew ill.

The arms 24| and 241 are held in their positions bysetscrewsorthelike.

Moreover, arheostat 25| mounted on a stationary partof the warper` and electrically connected with the field of the electromotor 4| by lines 2|| 'is controlled by the slidable carriage 2|4 keyed to the shaft 23| 'of the rheostat 25|' is order-to-obtain a Vsubstantially constant traveli'll asbest shown in 2,-3, '1, ammi` l2. rior;v vthis-purpose, a'rack 242 meshing witha pinion stantially constant tension in the warp yarns as the diameter of the winding |84 increases.

Assume, at the start of a warping operation the adjustable divergent reed 42 is set in suchl a way. that the warp 34 (indicated by a dash and dot line in Fig. 8) passes between the points d and e of the reed. During the building up of the winding |34 on the4 beam the diameter of the windingis increased, 'so that therwarp is lifted from a. lower level into a higher level, for example, from the position 34' into the position 84" as shown in Fig. 7. At the same time, the swingable support |48, |42 carrying the pressure roll |32 is moved through the angle y, so that the carriage |18 supporting the reed 42 is lifted by means of the controlling mechanism |18, |12, |14, |18 through the distance c (see Fig. 3). Preferably, the members of the controlling mechanism are arranged and shaped in such a way, that the lifting of the reed corresponds to the lifting of vthe warp and the latter always passes between the two points d and e of the reed.

roller |14 of the member |12 slides along the surface of the cam 18. Thus, the controlling mech- 'anism |18, |12, |14, |18 is renderedinactive. and

the swinging of the pressure roll away from the winding on the beam does not ca'use a furtherI lifting of the reed and the table. If it is desired to produce a winding of a diameter smaller than that shown in Fig. '1, the position of the set screw 212 is changed in such a' way, that the abutment 214 contacts the screw 212 after a shorter stroke. Thus, the stopping means 212, 214 may be adjusted for windings of various diameters. Y

In order to hold the pressure roll |82 in the extreme position shown in Fig. 7 against the action of the weight |84 and the spring |88 during' the exchange of a beam, the following automatic locking mechanism is` arranged. According to Obviously, the guiding rods 238, 231 and the l table 248 connected with the carriage |18 are lifted simultaneously with the reed 42.

If, after the start of thewarping operation, the operator should find out, that the yarns of the warp are not uniformly distributed over the width of the beam inserted into the warper, the

desired uniform distribution of the yarns may easily be obtained by a slight re-adjustme'nt of the reed 42 in vertical and/or horizontal direction by the adjusting means |88, 282 and/or 222, 228.

When the warping operation is terminated and the warper is arrested in a manner to be described hereinafter, the pressure rcll is in the position |32" indicated by dash and dot lines in Figs. 1 and'l. According to Fig. 7, the pressure roll then is still between the flanges of the beam 44. In order to renderlpossible the removal of the full beam in the direction of its longitudinal axis as described above, the pressure roll should be further swung by hand into the position shown in full lines in Fig. 7. For this purpose, a handle 210 is arranged on the arm |42 (see Figs. l and 6). During this manual swinging of the pressure roll from the position |32" (Fig. 7) in clockwise direction, a further lifting of the reed 42 and the table 248 is undesired, as the warp remains in the same level. Therefore, adjustable means are provided for rendering inoperative the controlling mechanism |18, |12, |14, |18 when, after the termination of the warping operation,

- the pressure roll |32 i's movedraway from the winding on the beam. As best shown in Figs. 2, 3 and 8, an adjustable set screw 212 is -arranged on the member l| 82 for cooperation with an abutment 214 secured to the slidable carriage |18. The adjustable set screw 212 may be set in such a way, that the abutment 214` contacts the set screw substantially simultaneously with the stoppage of the warper, when, for example, the pres- Figs. 3 and 6, a locking rod 218 carrying two set

collars

218 and 288 is shiftably arranged in

stationary bearings

282 and 284. A spring 288 arlof the warping operation, the crank |18 and cam 288 reach the position shown in dash and dot lines in Fig. 7, the locking rod 218 is still above the cam 288. Now, when the pressure roll |32 is moved away from the beam and the crank is swung into the position shown in full lines in Fig. 7, the inclined surface of the cam 288 contacts the locking rod 218 and displaces same against the action of the spring 288, whereupon, after disengagement of the inclined surface of the cam from the locking rod, the spring 288 returns the locking rod into its normal position now below the cam-288, so' that the locking rod 218 comes into engagement with the straight locking surface 284 of the cam 288 and holds the pressure roll |82 in its extreme position. In

order to release the pressure roll after the exthe locking rod 218 may be'released, so that the latter is automatically returned by the spring 288 into theposition above the cam 288 as shownv in Fig. 6.

The warper shown in the drawings has a first l brake associated with the drive and a second brake associated with the pressure roll, and means are provided for causing a substantially simultaneous application of said two brakes when 4 the warper is arrested.

sure roll and the members of the controlling y mechanism are in the position shown in dash and dot lines in Fig. 7, i. e. the pressure roll is in the position |32". Now, when thepressure roll is moved away from the winding on` the beam- According to Figa. 2, 3 and 4 a portion of the drive head 88 keyed to the shaft 82 of the electromotor .48 is in the form of a brake drum 284. One end of a brake band 288 embracing saiddrum is secured to a stationary element 288. the other end of said lbrake band-is secured 'to an arm 888 of a double armed lever 882 pivoted to the element 288 at 88,4. A tension spring 888 stretched between the other arm 888l of the double armed lever 882 and an extension 8|8 of the stationary element-288 tends to turn the double armed lever 882m counter-clockwise direction as viewed in Fig. 3 to-hold the brake in grip-r trically'connected with the electrical braking control means to be describedhereinafter. An excitement of the solenoid 3 I 6 causes a movement of the lever 302 in clockwise direction for an application of the

brake

294, 296.

According to Figs. 3 and- 4, a ring 326 of" leather or any other suitable material is mounted on the surface of the brake drum m facing the flange I of the beam. `When a beam is inserted into'a warper, the ilange |20 is pressed against said riiig 320,'so that the ring Vassists in the driving of the beam by friction.

As best shown in Figs. 3 and 6, a brake drum pressureroll |32. When the pressure roll is inserted into the bearings on the supporting arms |40, |42, a brake band 326 may be placed around the drum 322. One end of said brake band 326 is connected with a lug 326 on the arm |40,

' vthe other end of said brake band is connected with one end of a compensating means or tension spring 330 having its other end connected with` a crank322 keyed to a shaft 334 journalled in a bearing 336 of the arm |40. A tension spring 336 stretched between a pin 340 arranged on the arm |40 and an arm 342 keyed to the shaft 334 tends/to move the crank 332 in clockwise direction as viewed in Fig. 3 to hold the brake in released condition. I

The nrst brake 294, 296v associated with the drive of the'warper and the

second brake

322, 326 associated vwith the pressure .roll are'coupled with each other by means of a Bowden wire 344. One end 346 of said Bowden wire is secured tov the arm 306 of the double armed lever 302, while the otherend 340 of the Bowden wire is connected with'the arm 342. Thus, an excitement of the solenoid 3 I6 causes an application of the

first brake

294, 296 and, substantially at the same-time, .an application of the second brake 322, 32 6 through the medium of the Bowden wire and the tension spring 330 compensating for diiierences in the brakes. On the other hand, a deenergization of the solenoid 3|6 permits a movement of the lever 302 in counterclockwise direction `by the spring 306 for an automatic release of the two brakes. Of course, any other coupling between the two brakes and any other compensating means arranged between the two brakes could be used. if desired.

As pointed out above, the rheostat 266 serves to cause an automatic reduction of the opentduring the operation of the warper. Thel normal travelling'speed of the warp yarn is determined by said predetermined normal operating speed oit-the electromotor at the start of the warping operation. Different yarns of di'erent size to obtainthe proper tension in the yarns. Therefore, an additional electrical adusting means or a hand rheostat 360 (see Figs. 1 and 2)' is arranged on the warper for the adjustment of said predetermined normal operating speed of the driving electromotor 36. v ,Ithasbeenfoundthatawidespeedrangeof the electromotor 46 directly coupled with the s drive66ofthebeammaybeobtainedbyusing a D.

C'. motor .mfgenerator set 26 by means of aline 462 connecting the terminal 464 with a junction 'point 446 in thef line 366 and by means of ,lines 462 and 416 connecting the terminal 466 with a junction point 416 in the line 366.

w when the trip con magnet su is excited b'y mainswitch ia closed as will be described hereand/or material require different travelling speeds A vloaded Start push butt0n. The holding circuit` 'may be traced as follows starting from the lett hand terminal-of push button switch 382: The line 388, the ileld 394, the line 386, the rheostat 258, the line 388, the trip coil magnet 314, the line 386, the bridge of the overload circuit breaker 318, and the line 400 connecting the left hand terminal of the circuit breaker 318 with the left hand terminal of the start Apush button switch 382, said line 400' including the poleMz of the main switch M, the switch 402 of a counter stoprelay 404, the switch 406 of a warp brake relay 408, the electromagnet 4I0 of a time relay 4t2, and a stop push button switch 4I4 normally held in closed position by a spring (not shown).

The main switch M is opened and the supply of direct current to the electromotor 46 is interrupted at the pole M1, as soon as the above described holding circuit of the trip coil magnet 314 is interrupted either at the stop push button switch 4l4 or at the switch 406 of the warp brake relay 408 or at the switch 402 of the counter stop relay 404. The opening of the stop push button switch 4I4 takes place when the warper is arrested by hand, the opening of the switch 406 takes place when one or more control needles 416 in the creel drop and close a control circuit owing to a breakage or yarn as more fully' described in my copending patent application Serial #419.832, led November 21, 1941, and the opening of the switch 402 takes place when the normally closed switch 4I8 of the shut oi counter 98 is opened after the performance of a predetermined number of revolutions of the beam as more fully described in my copending patent application Serial #419,832, filed November 21, 1941.

Any of above mentioned interruptions of the holding circuit of the trip coil magnet 314 causes an energization of the brake solenoid 3i8 for l an immediate application of the brakes of the warper asA will be described hereinafter. The solenoid 3I8 is arranged in the following circuit:

- A line 420 branched of! at the point 422 from a rst line oi' the A. C. supply line leads to the

switch

4,24 of the time relay 4l2 and thence to one end of the solenoid 3i8. The other end of -the solenoid 3i8 is connected with the Junction leading from the electromagnet 434 lto the junction point 438, the line 388 from said junction point 438 to the trip coil magnet 314, the portion of the li'ne 388 leading from the trip coil magnet 3144to the Junction point 440, and the line 442 connecting Asaid junction point 440 with the electromagnet434. Thus, as soon as the holding circuit of the trip coll magnet 314 is interrupted at the stop push button switch 4I4 or the switch 406 or the switch 402, the described circuit including the electromagnet 434 is also interrupted, so that the electromagnet 434 is deenergized and the switch 430 is closed. At the same time the electromagnet 4l0 of the time relay 4I2 arranged in the holding circuit of the trip coil magnet 314 is also deenergized. Owing to the delaying action of the time relay 4I2, however, the switch 424 remains for a short period, for example 2 seconds, in the closed position 424 shown in dash lines, so that' the circuit ofthe brake solenoid 3i8 is closed and the latter causes a strong asa-1,6 12

application of the brakes of the warper as soon as the electromagnet 434 of the solenoid brake relay 432 is deenergized and the switch 430 is closed. After said short period of 2 seconds, for example, however, the switch 424 ofthe deenergized time relay 412 comes into the open position shown in full lines, s'o that now the ad- Justablechoke coil 433 is included in the circuit ofthe brake solenoid 3I8, whereby the energization of the .brake solenoid 3i8 is automatically Nreduced to a predetermined degree for causing only a slight application of the brakes oi the warper. Thus, after a short period of a strong application of the brakes for causing an immediate stoppage of the beam, a slight application of the brakes prevails as long as the motor 46 is arrested. As soon as the motor 46 is irestarted,

the electromagnet 434 arranged in parallel to the trip coil magnet 314 is excited, so that the switch 430 is opened and the brake solenoid 3i8 is deenergized for an immediate release of the vbrakes of the warper. The above described slight application of the brakes oi' the warper during the standstill of the motor 48 may be adjusted by the choke coil 433 to suchv a degree that it permits an unwinding of a portion of the winding on the beam by the storage device 22 but pre-V vents an undesired continuation of the rotation of the beam as soon as the storage device has been stopped for the termination of theunwinding operation.

Ii desired, however, the line 42| and the adjustable choke coil 433 may be omitted. Under these circumstances the solenoid 3i8 would be d deenergized as soon as the switch 424 of the time relay 4|2 comes into the open position, i. e. the brakes of the warper would be released after a short period of application corresponding to the delaying action of the time relay. v The hand rheostat 350 for adjusting a predetermined normal operating speed of the electromotor4 46 by controlling the voltage of the direct current supplied to the electromotor is arranged in the following circuit: A line 444 leads from the end 445 of the coil 446 of the generator ileld rheostat 360 to the pole M3 of the main switch M, whichin turn is connected with the junction point 448 in the lime 388 by a line 450. A line 452 leads from said junction point 448 to .the terminal 454 of the exciter 456 of theA. C. to D. C. motor generator set 26. The terminal 458 of the exciter 456 is connected with one endof the field 460 of the D. C. generator 358'b'y a line 462, The other end ofthe field 460 is connected with the movable ringer 464 of the hand rheostat 350 through a line 466 including the switch 468 of the relay `408. The end 441 of the coil 448 vof the hand rheostat 350v is connected with the junction ing to the junction point 414, through vthe portionA of the line 398 connecting the junction point-414 t with a junction point 416, and through a line 418 connecting the junction point 418 with the junction point 410. As will be apparent from the described connections, theA generator field 480 is energized by the exciter 458, which generates a constant potential. Thigpotential is applied to a circuit consisting of the,lei'thand portion (as viewed in Fig. 13) of the generator neld hand rheostat 350 in parallel with the generator iield 468 and the right-hand portionV of the generator field hand rheostat 350 in series with these. A movement of the iinger 464 across the hand rheostat 350 will cause a variation of the potential applied .to the generator neld 480 and, consequently, a variation of the current ilowin through this generator ileld during the normal operation of the warper.V If, for example, the linger 464 is moved to the right, the energization of the generator field and the current flowing through said generator field are increased. Therefore, the current flowing through the generator iieldis in proportion to the setting of the nger 464 of the lhand rheostat 868. This current, when high, gives a high voltage generated by the generator 366, when low a low voltage generated. The normal operating speed of the electrornotor 46 at the start of the warping operation is determined by the voltage of the direct current supplied to the electromotor, and, therefore, the normal operating speed of the electromotor may be easily adjusted by means of the hand rheostat.

The automatic rheostat 268 arranged iny series with the eld 384 ofthe electromotor 46 serves to reduce the speed of the electromotor from said normal value to a lower value, so as to obtain a soon asthe electromagnet 482 ofthe relay 488' is deenergized so that the switch 468 is closed..

In the first instance the electromagnet 482 is deenergized, as soon as the control circuit including the control needles 4| 6 in the creel is interrupted after the slack in the previously tied yarn has been taken up. In the second instance the electromagnet 482 is deenergized, as soon as during the warping operation as pointed out above.

Under certain circumstances, a very low speed or a so-called inching speed of the electromotor the tying of theends of the broken yarn without the use. of the storage device.. or, second, after the occurrence of a yarn breakage at a point between the creel and the beam and the tying of thel broken ends of the yarn subsequent to the unwindlng of a portion of the warp from the beam by means of the storage device. In lthe rst in stance the warp should be drawn from the creel at a very lowspeed, until the slack in the yarn has been taken u p, and in the second instance the warp folded in the storage device .should be taken up by the beam at a very low speed during the return of the gripping means 48 -by the reversible motor 488 from its lower active position into, its upper inactive position, until the warp is released by the storage device.

As more fully described in my copending patent application Serial #419,832, led November 21, 1941, and my Patent No. 2,302,700, issued on Nov. 24, 1942, the electromagnet 482 of the relay 488 is excited in both instancesmentioned above, so that the switch 468 is opened and the hand vrheostat 358 is disconnected from the generator iield 468.A According to Fig.. 13, an adjustable inching resistor l484 is arranged

betweenthe junction joints

486 and 488, so that, after the described disconnection of the hand rheostat.

368 from the generator eld 468, the current now flows rthrough the following circuit: exciter 4466, line 462, generator eld 468, line 466, inching resistor 484, line 444, pole Ma, lines 458, 462.

Therefore, under these circumstances a current proportional to the combined resistance of the generator field 468 andthe inching resistor 484 arranged in series with each other .will pass through the generator ileld, setting up a iiux which will produce the low voltage required for the low inching speed and the low torque of -the theainching speed switch 488 controlled by an element 48| arranged on the movable gripping means 48 o1' the storage device is opened when, y after the use of the storage device, the gripping I i means 48 of the storage device are arranged in series in a circuit including themain switch M for starting the electromotor; the control element 488' of the auxiliary start vswitch 482 oi the electromotor 46 is mechanically `coupled with the reversing switch 486 for the reversible motorV 488 of the storage device in such a way, that it causes 'A a closing of the auxiliary start switch 482' when the reversing switch is set for an upward movement oi' the gripping means 48 by the reversible motor.

In view of the foregoing, in the first instance, i. e. in case of a breakage oi yarn in the creel, an inching speed of the electromotor 46 is obtained by pressing and holding the spring loaded' start push button 882; as soon as the slack in the previously tied yarn has been taken 'up and the control circuit including the control needles 4I6 is interrupted, the electromagnet 482 of the` relay 488 is deenerized' andthe switch 468 is closed, whereby the-hand rheostat 858 is. reconnected with the

generator ileld

4,68, so that the speed of the electromotor 46 'rises to its4 set value and the electromotor Acontinues its operation at the high operating speed. In the second instance, i. e. in case of the use of the storage device, the electromotor 46' operates at inching speed, as soon as the reversing switch 486 mechanically coupled with Vthe control element 488 of the auxiliarystart switch 482 is set for upward movement of the gripping means 48, until the circuit including the main switch M is broken at the control switch 484 during the upward movement of the gripping means; the electro' motor 46 may be restarted at its operating speed by pressing the start push button 882, as soon as, after the return of the gripping means into its upper inactive position, the inching.l speed` switch 488 4has been opened, w'herebythe electromagnet 482 ofthe relay 488 has been.deen-. ergi'zed and the 'switch 468 has-been closed to reconnect the hand rheostat 868 withV the gener-- 88 is adiustably mounted qu'A the. rods` 64 so as to permit the ,insertion of beams of various` widths, the pressure roll |82 is exchangeable so as 'to permit the selection of la pressure roll ca- -pable of cooperation with a beam 'of predetermined width, and the divergent reed 42 is adjustable in horizontal and vertical direction. Therefore, the warper may be used for winding yam in various gauges, i. e. number of yarnsper inch, on beams of various widths as will be explained hereinafter` in connection with Figs. 14-16.

If, for example, the warper has been used previously for warping yarn in a gauge of 30 yarns per inch on a beam of a width of 10", and if, during the next warping operation, the warper shall be used for warping yarn in the same gauge of 30 yarns per inch on a smaller beam of a width of 8", the following steps are carried out: Assume, during the previous warping of the yarn on the 10"-beam, the beam 44, the bracket 56 with the idling head 80, and the reed 42 are in the position shown in full lines in Fig. 14, and a warp of 300 yarns passes between the points f and g of the reed. Now, the bracket with the idling head is brought into the dash and dot line position 56', 80', so as to permit the insertion of an 8"-beam 44'; the motor 46 and the driving head 50 coupled therewith remain in their position. A pressure roll capable of cooperation with an 8"-beam is substituted for the pressure roll used previously. The reed 42 remains in its position. 60 yarns are taken away from the warp, so that a warp of 240 yarns only passes between the points f and m of the reed 42, said points being spaced from each otherat a distance of 8".

Therefore, the beam of a width of 8" receives 240 yarns per 8", or, in other words, the yarns are wound on the 8"-beam in the same gauge of 30 yarns per inch, as they have been Wound previously on the 10"-beam.

If, for example, the warper has been used previously for warping yarn in a gauge of 30 yarns per inch on a beam of a width of 10", and if, during the next warping operation, the wanper shall be used for warping yarn in a. different gauge of 2'5 yarns per inch on a beam of the same width of l", the following steps are carried out: Assume, during the previous warping of the yarn on the "-beam, the beam 44, the bracket 56 with the idling head 8U, and the reed 42 are in the position shown in full lines in Fig. 15, and a warp of 300 yarns passes between the points f and g of the reed.` Now. the bracket with the idling head remains in its position relative to the rod 64 so as to permit the insertionof another 10"-beam. The pressure roll is not exchanged. The reed 42, however, is brought into the position 42' as shown in dash and dot lines in Fig. 15, so that the point h. takes the place of the point f and the point i takes the place of the point g. Furthermore, 50 yarns are taken away from the warp in the space between the points i and k, so that a warp of 250 yarns passes between the points h and i of the reed in the .position 42', said points being-spaced from each other at a distance of 10". Therefore, the beam of a width of 10" receives 250 yarns per 10", or, in other words, now the yarns are wound on the 10" beam in a'. gauge of 25 yarns per inch. In order to move the reed from the full-line position 42 into the dash and dot line position 42', preferably at 'rst the reed is shifted in a vertical direction Y (see Fig. 16) so that it comes into the intermediate position 42" as shown in dash lines, whereupon the reed is moved from said intermediate position 4 2" into the new position 42', in a horizontal direction Z. Of course, the horizontal and vertical adjustment of the reed could'be reversed or carried out simultaneously, if desired.

Although preferably the individual vobjects of the invention are applied to a. warping plant-'in -in partial combination to warping or beaming machines. It is emphasized that the merits of the invention are not limited to the described and illustrated combination, but the individual objectsof the invention per se also have inventive merits. Without statingl that all the, individual objects of the invention are enumerated, itmay be mentioned that, for example, the direct coupling between the driving electromotor and the driving means of the beam could be arranged in a Warper, which is not equipped with means permitting the insertion of the beam in the direction of its longitudinal axis, or that the means for adjusting the warper to the size of the beam to be inserted could be arranged in a warper which has no direct coupling -between its drive and the driving means of the beam, or that the controlling means for lifting the reed in accordance with the increase of the diameter of the winding on the beam could be arranged in a warper wherein the automatic controlling means for reducing the speed of the drive are separated from said controlling means for lifting the reed, etc.
