Our invention consists in improvements in mechanism for acting upon a series oit' elements such as the threads of a warp and is intended more particularly to provide means ior maintaining a Cooperative alinement between a progressively acting operating mechanism such for example as the needle oit' a warp drawing machine and the individual members of two or more separate groups of elements, which members are intended simultaneously to be acted upon by said operating mechanism. Such hy way oi? illustration may be the threads o'l the warp, the series ot heddles in the harness and the splits ot the reed in the warp drawing' machine referred to.

Our invention is not'limited lin its ap'plication to any particular purpose or to any particular machine 'or apparatus but by way of illustration, in the accompanying drawings we have shown one form et the same embodied ini a well-known type `of Warp drawing machine, many features of which are shown in patent to M. F. FieldNo. 755,861, dated March 29, 1904-.

In a warp drawing machine as ordinarily constructed, the warp threads are-helddistended in a generally gparallel relation and adjacent to the warp is arranged the harness and the reed in the same general relation which they are to occupy in the loom. lperating mechanism comprising a needle or hoolrand appropriate driving mechanism uponv a moving carriage is given 4a progressive step by step movement erosswise 4the reed, the 'harness and the warp, Iat each adance of the carriage the needle bei-ng caused to move forward between the splits of the reed, through theeye of the-heddle to seize i one of the warp threads and draw the said Specification of Letters Patent.

thread back again through the heddle eye and the reed. The carriage then advances to permit a repetition of the same operation upon the next adjoining thread. In the warp drawing machine as generally constructed, the step-by-step advance of the operating mechanism is designed with reference to the spacing of the heddles and, `ifi this be 'different from the spacing of the warp threads or the reed splits, some corrective or compensating movement of the warp threads or the reed or both with reference to the heddles becomes necessary. Ordinarily the total width of the warp is materially greater' than the total width of the harness ,and frequently the warp threads are irregularly spaced, in the one case causing the warp threads to increasingly depart from correct alinement with the operating mechanism, and in the other causing irregular departures from the proper alinement. y K

In the accompanying drawings we have shown one embodiment ot' your invention applied to a warp drawing machine, so that the individual members of the. heddles and the warp threads and the reed splits are brought into cooperative alinement with the operating mechanism to permit the latter to act simultaneously upon the individual members oi' these three groups of elements, even though the latter tend normally to be out ofalinement with each other,`

Our invention will be best understood by reference to the following description, taken in connection with the accompanying drawings, which show, for illustrative purposes, one embodiment th ereof; while its scope will be more particularly pointed out in the appended claims.

In the drawings we have shown a warp drawing machine of the general type illustrated in patent to M. F. Field No. 755,861. The general -function of this machine is to support the warp, the harness and the reed in the general relation which they will sub sequently occupy in the loom and there to permit appropriate mechanism to draw the individual threads et the warp through the appropriate heddle or' the harness and be tween the splits of the reed preparatory to placing these several elements with the drawn warp in the loom.

For a description ot the details ol' the operation ot this machine reference may be had to the above-mentioned patent, it being suilicient for the purposes ot our invention here to point out only the general operation thereof. The harnesses, oi which herein there are two,-a front set (t and a rear set a, and the reed b are suitably supported transverse to the line of action of the drawing-in needle c, which latter is mounted for reciprocative movement, together with the needle operating mechanism upon the trav cling carriage ci. The latter is mounted to travel through a step-by-step movement upon suitable ways lengthwise the frame oif the machine and parallel with the reed and harness, the mechanism for reciprocating the needle and advancing the carriage at appropriate times being actuated from drivnig shaft d moving with the carriage and receiving its movement from some suitable source (not shown). `When the needle is ready for its 'forward movement upon the carriage, the arm ii is caused to move forward to separate the splits ot the reed at the appropriate point so that the needle may with certainty pass through the desired space therein. As in the prior patent reierred to the reed is supported somewhat loosely upon bearings b2 permitting .it to yield or slide longitudinally so that it the splits are irregularly spaced or Vfor any reason out ol alinement with reference to the hed-illes the reed frame will be ven a slight longitudinal movement by the arm Z/ which has an approliriately shaped nose, to bringl the same with certaii'ity into coi-rect alinement for the action of the operating mechanism.

Suitable harness spreading and separating mechanism c2, fully disclosed in the sai d prior patent, advancing with the carriage and bearing a definite relation thereto, is

caused intermittently to act upon the successive heddles of the harness so that the appropriate heddle eye through which the warp thread is to be drawn is separated in turn from the others and held within the path of the advancing needle.

Then the needle advances it passes between the separated and properly alined reed splits, and through the appropriate heddle eye, which latter is maintained by the separating mechanism in certain alinement with reference to the needle path. Further advancing the needle is caused to partially turn and seize a warp thread the latter be ing shown with reference to the reed and the harness eyes at c (Fig. l). The needle is then immediately retracted drawing the thread through the heddle eye and between the splits of the reed, the thread being disengaged trom the needle by a transverse movement of the knock-off linger d2. The needle having been fully retracted, the carriage is advanced another step, the arm 1) moved into the next adjacent space between the reed splits and the harness separating mechanism turned to maintain the next successive heddle eye in the advanced path of the needle. The operation is then repeated and again repeated untilthe entire warp has been drawn through the harness and thc reed.

The warp threads pass upward from the warp beam r (not shown) through a. gripping member or bar c (Figs. l and 5) over a shaft c2 which carries means for irst stretching and then separating the threads, and to a second gripping member or bar c3. The gripping member c3 clasps the threads with a relatively slight friction but the gripping` n uab-er c with a relatively greater friction, so that as the threads are seized and drawn by the needle the loose ends thereof pass readily from the gripping member c3 but remain firmly held in the gripping member c. The action of the machine so lar described and the general construction and arrangement ol parts is substantially that ot lthe well known warp drawing machine a type olt which is disclosed in the prior patent referred to.

rlhe warp separating device c4 herein comprises spreading and separating means carried upon the shaft c2, the latter being liournaled in hangers carried by the standards d3 secured to and travelingr with the carriage (Lione of the said standards being shown in Figs. l, 3 and 5.

The separating mechanism is therefore caused to advance with the carriage and act upon the successive threads of thewarp, sai d shaft c2 vbeing given an intermittent rotation in a well known way by gearing driven from the carriage. Referring to 5, the action of the Warp separating device will be readily understood. The shaft e2 toward its active end is of increasing diameter and, as it advances beneath the threads of the warp, gradually increases the tension thereupon, suitable corrugations G5 being proA lGO vided .to stroke the threads into parallel position. As the carriage and shaft c2 advance the successive warp lthreads engage the lip of the warp separating feed screw portion c and are selected and separated one at a time and advanced by the intermittent rotation ofthe screw until-they reach the final position of the warp thread c. The separating screw having a fixed relation with reference to the carriage and therefore to the path ofthe needle the finalposition as-A sumed bythe thread may be and is made to lie with certainty within the needle path.

It will be seen that where the width of the warp is greater than the width of the series of heddles in eachxharness, the successive warp threads will depart more and more from a position of alinement with the corresponding heddles and from alinement with the needle which latter. advances at each operation just enough to pass through the next separated heddle eye. Although the warp threadseparating screw willotend to bring the warp threads into a position of alinernent with the needle yet if the warp is unmoved its threads become more remote with reference to the. feeding screwitself as the operation proceeds. It is found to be' important for the effective action ofv the separating ldevice that the warp threads should meet the screw e at an angle which. approximates the pitch of the screw thread7 but if the warp threads are fixed in position this angle will continually decrease and will soon become too little to permit separation of the thread by: the screw.

In order to provide a corrective movement to correct the changing relation between the operating mechanism and the warp threads, the warp beam and the gripping bars e and e3 are mounted upon a frame or carriage, which can be moved. lengthwise the machine to provide the necessary compensating movement forthe warp.

Referring to Figs. 3 and 4, wherein the construction of one end of this frame -or carriage is partially shown, thelatter consists of the two end supports c7 which are hung upon. the horizontal rods es, the` latter adapted to move lengthwise over the horizontal grooved ,guiding rollers c". The clamp bar c is secured directly to the end piece c7, while the .clamp bar c3 is adj ustably pivoted upon the rod 610, the latter being secured to the said end piece e?. The opposite end of the carriage is similarly constru cted. The` compensating adjustment of the warp carriage may be manually effected through the rotatable rod (Figs. Sand 4) the latter being geared by the beveled gears f to thetvertical shaft f2, the lower end of the said shaft f2 having secured thereon the pulley f3. An endless band fx `embraces the pulley f3 and a corresponding V*pulley (see Fig. 2).-at the oppositeend of the machine,

ably but` rigidly secured (Fig. 6) as'by means of the pinsy f7 to rotate with the pinion f6, the teeth. of the said pinion being in-engagement with the rack 1- (FigA 2) secured to and movable with the warp carriage. If now the roll or. rod f is turnedV by hand the vertical shaftA f2 and pulley f3 is also turned, and movement of the'band fX effected. .This turns the pinion f6, and causes the longitudinally 'movable warp carriage ylaterally to advance or recede relatively to the pinion and therefore to the operating carriage d which carries the pinion; Thus, in the machine illustrated the positionlof the warp may be adjusted from time to time by hand to compensate either for irregularities in the spacing of the warp threads or to offset the continually advancing position-which the said warp threads bear to the operating mechanism as the drawing-in operation proceeds.

rFor greater efficiency however, this corrective movement vshould be automatic and regulated by the progress of the drawing-in operation and in the machine illustrated we have provided means which act-automati- 'cally to move the warp, such means being thrown into and out of operation by the charging position of a feeler finger, the latter being controlled by the position of the warp threads relatively to the operating mechanism. This is accomplished in the following manner: The shaft goto which is keyed the` band wheel f5 passes downward beneath its supporting frame and is rigidly secured to the ratchet wheel g', whereby a turning of the latter will cause the corresponding movement of the pinion f6 and a compensating movement ofthe warp car-- ringe. vThe turn of the ratchet wheel is effected by a pawl L (Fig. l), pivoted upon the recilnocating pawl actuating rod h', the latter being connected to the oscillatingr link h2, the latter moved by the rod h3, connected to the needle actuating lever h4. The connection is such that when the needle is moved inwardly the pawl actuating rod is also moved inwardly and carries the pawl idly over the teeth of the ratchet wheel. When the needle is retracted the pawl actuating rod is also retracted, and if the pawl is permitted to engage with the teeth of the ratchet wheel it effects a slightmovement of the ratchet wheel and therefore of the kwarp carriage,as described. The compensating movement' of the Warp carriage is therefore effected as it should be while the needle is in its retracted position.

The means which automatically .control iis y the operation of this warp compensating mechanism, is as follows. Swingingly mounted upon the arm Z4 of the mechanism carriage, is the feeler finger z', having a properly shaped nose z" correctly positioned to underlie the foremost of the warp threads provided the latter are in the correct or the desired alinement with reference to the separating screw c4 or other elements of the operating mechanism. In Figs. 4 and 5 the warp threads are illustrated as having the desired relation to the separating screw, and the nose '11 of the swinging .finger is held downward against the under side of the foremost warp threads, causing its opposite and angularly turned end 2 to bear against the heel of the pawl lifting lever le, which is fulcrumed upon the pawl actuating rod 71,. rlhe lever is provided with a pawl lifting linger 7c', which has an inturned end engaging a curved slot 71,5 in the pawl, the proportions of these several parts being such that' when the nose of Vthe feeler is held downward by contact with the warp threads, the lifting` lever K is forced backward and the pawl maintained out of engagement with the teeth of the ratchet wheel g', the reciprocations of the pawl actuating rod being ineffective to cause movement of the warp carriage.

As the drawing-in operation proceeds, the warp threads will become farther advanced relativ dy to the needle and the nose of 'the feeler finger and their angle of inclination to the separating screw less, so that finally the witlnlrawal of the foremost warp tin-earl will free the feelcr and the advance of the operating` carriage will be insuliicient to bring its nose under the next succeeding warp thread. rllhe 'nger will then move to the position shown in Fig. l, permitting' the lifting lever /c to swing forward and drop the pawl into engagement with the teeth of the ratchet wheel. The weights of the parts can be so adjusted as to permit the nose of the `teeler linger to press upward against the warp threads with any desired tension, but preferably they are proportioned to permit the pawl slightly to overbalance the linger so that the upward tendency of the latter is elatively slight and slight variations in the tension of the warp threads will not affect the operation of the device. llVhen the feeler linger mores to the position shown in Fig. l, each reciprocation of the pawl mores the warp carriage slightly from right to left,r as viewed in Fig. o, and this compensating movement will continue by repeated slight increments until the desired alinement of the warp in the separating mechanism is obtained. Each retraction of the pawl operating rod 71, is accompanied by rearward movement of the lifting linger 7c, and the inturned end of the feeler linger, so that the nose z" of the latter moves from a position above the plane of the warp threads on advancement of the pawl to a position below the plane of the same on retraction of the pawl. if the corrective movement occasioned by the retraction of the pawl is suliicient to bring the next warp thread within the path of movement of the feeler finger nose, movement of the latter is arrested on the advancing of the pawl and the latter is again withdrawn from engagement with the teeth of the ratchet wheel and into the position shown in Fig. 4. Thus it will be seen that the nose of the feeler linger being located in the place where the foremost warp thread ought to be for the best conditions of operation, if the foremost warp thread is not in its designed position in contact with the feeler finger, the warp carriage will be automatically adjusted through a step-hy-step compensating movement to bring the leading warp thread into the desired position.

ln the description of the machine, it has been assumed that the endless band f has no effect upon the automatic feed of the warp carriage, and in fact this is the case in the machine illustrated, for, hy reference to Fig. 6, it will be seen that the pitch circle of the band wheel f5 is substantially equal to the pitch diameter of the pinion fl", so that as the operating carriage moves the pinion and band wheel along, the former will roll idly upon the rack and the latter upon the endless band.. l

lf the total width of the warp is less tha the total width of the harness, instead of greater, as has hereinbefore been assumed, the resultant compensating warp feed must be in the opposite direction to that described,

that is to say, as the drawing in operation" progresses, the position of the warp threads will lag behind that of the corresponding heddles and the inclination between the warp threads and the separating mechanism will become greater and greater. To correct this the warp should he moved from left to right, as viewed from the rear in F ig. 5, instead of in the opposite direction. In order that this may be effected hy the same mechanism as has been described, we have provided means so that the step-hystep movement of the operating carriage from left to right (as viewed from the rear in Fig. may be made to cause a step-by-step movement of the warp in the same direction but farther than is required Vto compensate for the increase in pitch of the warp threads, the automatic compensating feed when brought into action by the feeler linger being then permitted. to move the warp carriage back again from right to left by an increment which is sufficient always to insure the correct alinement of the warp threads.

To accomplish this, the band wheel f5 is removably mounted on the shaft g and may be replaced by one having a greater pitch diameteil than that shown in Fig. G. lf'this is done, each step-by-step advance of the operating carriage which carries the shaft Will cause a smaller angular movement of the band Wheel than before, consequently the pinion f will roll idly upon the rack r to lesser extent and will cause the rack to movefrom left to rightv and thus carry the Warp along in the direction of travel of the mechanism carriage. The amount of this movement'tvhi'ch is dependent upon the size of the band Wheel f5 is preferably greater by a slightincrement than is necessary to properly adjust the warp and on the nent retraction of the needle, if the movement of the Warp has been too great and the foremost thread thereof is not in proper alinement, the rise of the feeler `finger will throw in the automatic compensating movement for the Warp. Y

It is to be observed that in the specific embodiment of our invention illustrated, the warp carriage is positively positioned relatively to the mechanism carriage b the compensating motive mechanism, an that this motive mechanism is at all times under the controlv of the delicately adjustable feeling means. The latter may, of course, be embodied in a great variety of forms. The feeler iinger or member has a movement transverse to or crosswise of or to and from the plane of the Warp, instead of in vor substantially in the plane thereof. It Will be evident from the foregoing description and from the illustration, and particularly F ig.,

5, that'the nose or operative portion of the feeler inger contacts with a plurality of the leading Warp'v threads. i This construction is of importance and is preferably employed by us. A feeler finger vibrating or moving in the plane of the Warp tends to roll the thread back from the point of action of the separating mechanism, and tends to roll them over one another. This action is eliminatedy or prevented when the feeler linger Works across or transverselyL of or to and from the plane of the Warp'. It will also be observed, viewing Figs. 4 and 5,' that the feeler is made operative uponthe thread at a point relatively remotey from the point of action ofthe separating mechanism. This is o'f practical importance, inasmuch as the operation and character of the Warp separating mechanism herein illustrated are not dependent yupon the controlling with absolute nicety of the slope of the threads to be separated. The feeler finger therefore may advantageously be located at a kpoint relatively remote from the point of action of the Warp separating mechanism. l3`urthermore, y the feeler finger need not kWork so accurately y as if the thread next to be separated or picked ofi' had to be located With great eX- actness by the action of the separating mechanism. i

These principles and features of operation of the feeler iinger or member may be employed, Within the scope of our invention, invarious types of Warp separating or selecting machines, and We are therefore not limited to theL use thereof in connection with a mechanism of the drawing in type. i

Obviously, the presence or absence of the, Warp threads might be made to control this mechanism by either stopping or starting the movement of the feeler finger, or by acting upon the motive mechanism in any Way to throw it in or out of operation at the desired times. A construction like the one shown, however, has the advantage of simplicity, delicate' adjustment and sensitiveness. The vibratory movement of the feeler and its connection to the reciprocating driving mechanism of the needle is advantageous also, in that the control of the feeler finger over the operative connections between the reciprocating mechanism and the compensating mechanism is periodic and times the advance of the Warp carriage relatively to the needle carriage exactly with the retractions of the needle. A

Ve have here described one embodiment of our invention as applied to a common95 type of VWarp drawing machine. It isto bef understood however, that it is shown of the construction and inthe connection describedl for illustrative purposes only and vis notl limited to the particular details or the special 100 use referred to herein, 'but on the contrary is susceptible of application to other uses which A will be apparent to those skilled in the art, wide departures from the construction and arrangement disclosed, and of embodiment 105 in a variety of forms to which reference here is unnecessary.
