MACHINE FOR OPERATING UPON WARPS.

Specification of Letters Patent.

Patented J une 8, 1920.

Application filed July 30, 1917. Serial No. 183,445.

To all whom it may concern.

residing at Rockford, in the county of Win-- nebago and State of Illinois, have invented certain new and useful Improvements in Machines for Operating upon Warps, of which the following is a specification.

One of the objects of this invention is to provide simple mechanism for selecting successive threads of a warp and disposing them in position for action thereon by a warpdrawing, warpuniting or other mechanlsm.

Another object of the invention is to provide means for. suspending the action of a warp-drawing needle in case no thread is presented to the needle by the thread-positioning mechanism.

A further object is to provide simple means for sensitively controlling the relative feed movement between the mechanism and the warp.

A specific object of the present invention is to provide a simple, inexpensive machine for drawing warp threads through the heddle eyes of loom harnesses.

In the accompanying drawings, Figure 1 is an end elevation of a machine embodying the features of our invention, a portion of the mechanism which is mounted upon the traveling carriage being omitted. Fig. 2 is an elevation of the opposite end of the machine, a portion of the guard 114: being broken away. Fig. 3 is a front elevation of the machine with parts broken away, Fi 4 is a fragmental top plan view. Fig. 5 is a vertical sectional view taken in the plane of line 5-5 of Fig. i. Fig. 6 is a perspective view f the thread-selecting and separating mechanism and the drawing-in mechanism. Fig. 7 is a view of the carriage which supports said mechanism, showing also the thread-selecting and separating mechanism and the means for feeding the carriage. Fig. 8 is a view of some of the parts shown in Fig. 7, the view being taken in the plane of line 8 of Fig. 10. Fig. 9 is a view similar to that of Fig. 6 and illustrating the action of the stop mechanism. Fig. 10 is a fragmental top plan view of the parts shown in Fig. 7. Fig. 11 is a view similar to that of Fig. 10,,but showing the parts in a different position. Fig. 12 is a view similar to those of Figs. 6 and 9, illustrating the parts 1n the position assumed upon the completion 'of a drawing-in action. Figs. 13, 14, 15, 16

and 17 are views showing successive positlons of the separator disk and the drawingin needle. Flg. 18 1s a fragmental detail View of a needle guide.

In the drawings, A denotes a loom beam, 13 a warp and C a loom harness. WVhile only one harness is illustrated in Figs. 1 and 2, in practice the warp threads are drawn through two or more harnesses. The harnesses are suspended in parallel vertical planes, and that portion of the warp which 1s engaged by the thread-selecting mechanism is supported in a vertical plane parallel with the harnesses.

Any suitable means may be employed to support the loom beam A. Herein are shown two posts 1 adapted to support the trunnions of the beam. In order to accommodate beams of different lengths, the posts 1 are adjustable toward and away from each other upon two rods :2, being secured upon said rods by means of clamps 3.

To hold the beam against rotation, I provide a brake comprising a brake member a attached to arms 5 fixed upon a rock shaft 6 which is journaled in the machine frame. To the shaft 6 is keyed an arm 7 which is connected by means of a spring 8 to a hand lever 9 rotatably mounted on the shaft 6. The hand lever 9 may be secured in adjusted position by any suitable means, as, for example, a ratchet bar 10 fixed to the machine frame and a catch 11 on the hand lever ar ranged to engage said bar. When desired, the brake may be temporarily released by means of a pedal 1 (Fig. 2) which is rigid with the arm 7. For preparing the wrap for the drawing-in operation, a carding bar 13 is provided, said bar being covered with card-cloth and being supported upon arms lafixed in the machine frame. The carding bar 13 extends substantially parallel with the axis of the loom beam. The arms 1% are provided with stops 15 against which a warp clamp D may be laid. In preparin the warp, the lower half of the clamp is laid upon the bars 14L and the warp threads carried over said bar and placed upon the carding bar 13. The threads are then brushed to straighten them out, a fter which the upwith rubber strips 21.

per half of the clamp is laid upon the threads and the two halves of the clamp secured together.

. The means for supporting a portion of the warp in a vertical plane parallel with the harnesses comprises a bar 16 secured in the machine frame and a clamp located above and extending parallel with said bar. While any suitable form of clamp may be used, that herein shown comprises an angle iron 17 (Fig. 5), the end portions of which are fixed to two levers 18 secured between their ends to shafts 19 journaled in the machine frame. The rear ends of the levers 18 are provided with weights 20. The inner surfacesof the angle iron 17 are provided The warp clamp further comprises a roller 22 covered with suitable friction material and journaled in arms 23 which are pivoted upon the shafts 19. A suitable number of spring clamps 24 may be placed over the roller 22 and the angle iron 17 to hold the roller in engagement with the warp. The arms 23 may be swung rearwardly to support the roller in inoperative position, as shown in dotted lines in Figs. 4 and 5, the roller being supported in such position by means of projections 25 on said arms resting upon the levers 18. 26 are stop pins on the frame to limit downward movement of the weighted levers 18. To hold the angle iron 17 temporarily in a position below that normally occupied, suitable means may be provided, as, for example, arms 27 fixed to the shafts 19 and having pivoted thereto arms 28 arranged to be swung under stop pins 29 set in the machine frame.

Assuming that the warp has been brushed out and secured in the clamp D, the beam brake released, the roller 22 swung back into the dotted-line position shown in Fig. 5, and the angle iron 17 held depressed by engagement of the arms 28 beneath the stop pins 29, the sheet of warp threads is put in place and tensioned as follows: The clamp D is carried forward beneath the bar 16 and upwardly over the angle iron 17. The roller 22 is then swung forward to hold the sheet of threads against the angle iron 17, and the spring clamps 24 are put in place, thus loosely clamping the sheet of threads. The clamp D is now removed and the thread ends extending rearwardly of the angle iron 17 trimmed to the desired length, The beam brake 4 having been applied, the arms 28 are swung out from under the stop pins 29, thus allowing theweighted levers 18 to move the warp clamp formed of the angle iron 17 and the roller 22 away from the bar 3, thus putting tension upon the warp threads. The tension may be varied by adjusting the position of the weights 20 upon the levers 18.

The loom harnesses may be supported by rlage.

any suitable means. That herein shown comprises a bar 30 (Figs. 4 and 5) removably supported in slots 31 in the machine frame. Upon this bar are slidably supported two vertical bars 32. Slides 33 are vertically adjustable upon the bars 32 and may be secured in place by means of clamp screws 34. The slides 33 are notched to support the ends. ofthe upper shafts C of the harnesses. If desired, weights 35 may be hung upon the lower shafts C of the harnesses to keep the heddles taut.

To keep separate the two longitudinal series of heddle eyes C of each harness, we insert in each harness a rod C, said rod extending between the two series of upper heddle strandsvand being supported at its ends upon slides 36 on the bars 32. The slides 36 may be fixed at the desired height by means of clamp screws 37 The mechanism for selecting warp threads singly and in regular succession and for drawing selected threads through the eyes C of the harnesses is mountedfor movement from left to right ,(Fig. 3) transversely of the warp and the harnesses. Said mechanism is mounted upon a carriage 39. The carriage is provided with grooved rollers 40 which run upon a rail 41 and with plain rollers 42 that run within a grooved rail 43. The carriage is caused to travel by means of a pinion 44 (Fig. 7) meshing with rack teeth 45 formed in one side of the grooved rail 43. The pinion 44 is fixed upon the lower end of a shaft 46 journaled in the carriage 39. To the upper end of the shaft 46 is fixed a ratchet wheel 47 arranged to be engaged by a pawl 48 which is mounted upon a pivot stud 49 carried by a lever 50. A torsion spring 51 tends to swing the pawl 48 toward the ratchet wheel. The lever 50 is pivoted upon the carriage 39 at 53 and is arranged to be swung by means including a roller stud 54 carried by said lever and lying between two bars 55. The bars 55 are fixed to levers 56 which are secured to a rock shaft 57 journaled in the machine frame. The bars 55 extend parallel with each other and form between them a groove extending from one side of the machine to the other and containing the roller stud 54 in any position of the car- Any suitable means may be employed to rock the shaft 57. That herein shown comprises an arm 58 (Fig. l) rigid with said shaft and connected by means of a pitman 59 to a crank arm 60. The crank arm 60 is rotatably mounted upon a .stud shaft 61 fixed in the machine frame. Rotatably mounted upon said shaft is a drive pulley 62 arranged to be driven by a belt from any suitable source of power, said pulley having a clutch face 63 (Fig. 3) arranged to engage a similar clutch'face 64 on the crank arm 60. The hub of the pulley 62 is peripherally grooved to receive pins 65 (Fig. 4) carried by a yoke 66. Said yoke is pivoted at 67 (Fig. 8) to the machine frame. An expansion spring 68 tends to move the yoke in the direction to slide the pulley 62 into driving engagement with the crank arm 60. The drive pulley may be moved out of engagement with {the crank arm by suitable means, as, for example, a treadle 69 comprisingarms 70, 71 and 72 (Fig. 3), these arms being fixed upon a rock shaft 73 (Fig. 1). Rigid with the arm 7 O is an arm 74 which is connected by means of a rod 75 to an arm 76 which is rigid with the yoke 66. When it is desired to lock the pulley 62 out of engagement with the crank arm 60 a stop lever 77 may be swung into position to obstruct upward movement of the arm 70. The lever 77 is pivoted to the machine frame at 78.

A tension spring 58 (Figs. 1 and 3) connected to the arm 58 and a stationary part of the machine serves to counterbalance the arm 58, the connecting rod 59 and the crank arm 60, so that when the clutch is thrown out said parts shall stop at once and not gravitate to their lowest position.

7 Although the rock shaft 57 normally oscillates continuously, the carriage 39 is not advanced regularly but, on the contrary, the pawl 48 is permitted to engage the ratchet wheel 47 only when necessary to maintain the selecting mechanism in proper relation to the warp, as will be explained hereinafter.

A disk 79 is mounted upon the carriage 89 for rotation in a horizontal plane, the edge of said disk being finely milled. The disk is so located that, as the carriage 39 advances, the edge of the disk will come into contact with the foremost warpthreads (as indicated in Fig. 10), the friction between the disk and the threads causing the disk to turn as the carriage progresses. As the carriage advances, the disk 79 causes the foremost warpthreads to be bowed forwardly out of a straight line between the bar 16 and the warp-clamp member 17, thus putting additional tension upon the threads.

The selector mechanism comprises a selector 80 having a hook or other suitable thread-engaging element 81 intermediate its ends and upon one side. The selector 80 is fixed to a pivot which is mounted in point bearings upon the lever 50. A torsion spring 83 (Fig. 9) surrounding said pivot tends to swing the selector toward the unselected warp threads. The tension of said spring may be adjusted in any suitable manner. Rigid with the selector 80 is a rearwardly extending arm 84: (Fig. 8) carrying a pin 85 which is arranged to slide along the edge of a cam plate 86 on the carriage 89. Attached to the arm 84 is a flexible or yieldable stop 87 against which the torsion spring 51 tends to hold the pawl 48. As the carriage 39 advances, the constantly-reciprocating selector 80 engages the foremost warp thread and moves said thread forward, the thread slipping between the

clamp members

17 and 22, the thread being deposited by the selector upon a separating device hereinafter described. As the selector is moved rearwardly, the torsion spring 88 swings the selector into contact with the next thread to be taken. If said thread occupies a certain position, the selector will be prevented from swinging so far as to allow the pawl 48 to engage the ratchet wheel 47 upon the rearward movement of the selector. But if the foremost thread stands in such position that the selector swings so far as to allow the pawl 418 to engage the ratchet wheel 17, said ratchet wheel will be turned and the carriage advanced a slight distance, thus pressing the selector against the foremost thread. Inasmuch as the pawl 48 is then engaged with the ratchet wheel, the selector would crowd the foremost threads together, were not the stop 87 made flexible to allow the selector to yield slightly.

The separator device may be of any suitable construction. That herein shown consists of a disk 88 mounted upon the carriage 89 to rotate in a horizontal plane, said disk projecting forwardly beyond and partially overlying the milled disk 79. In the edge of the disk 88 are formed teeth or shoulders 89 into the path of which a thread is carried by the selector 80 during the forward or selecting movement of said selector. The disk 88 is rotated step by step by suitable means, asfor example, a dog 90 pivoted on the lever 50 and held in contact with a ratchet wheel 91 fixed to the disk 88 by means of a tension spring 92. As the separator disk 88 rotates, it spaces the selected threads apart and advances them into position to be engaged by the drawing-in needle. 93 (Fig. 10) is a spring finger that engages the ratchet wheel 91 and serves to prevent reverse rotation of the separator disk.

The drawing-in needle 94; is provided with a flattened head 91 having a notch 94. The needle is carried by a framework 95 fixed to the carriage 39, said framework being arched to clear the harnesses. The needle is slidably mounted in guides 96 (Fig. 12) on the framework 95. The means for reciprocating the needle comprises a lever 97 pivoted at its lower end to a block 98 fixed to the needle. The lever 97 is pivoted between its ends to a fulcrum lever 99 that is pivoted to the framework 95. A tension spring 100 connected to the fulcrum lever relieves the .needle of more or less of the weight of the Means is provided whereby the action of the needle will be suspended in case a thread is not brought into position to be taken by the needle. This means comprises a lever 105 pivoted intermediate its ends to the framework 95, the lower end of the lever being bent to lie in the path of the threads carried toward the needle by the separator disk. The upper end portion of the lever 105 has a shoulder 106 to underlie the bar 101 and support said bar above the path of movement of the bar 104. A tension spring 107 tends to draw the upper arm of the lever 105 against the bar 101. Inasmuch as the lower end of the lever 97 travels in a straight line, the upper end of said lever has a considerable riseand fall during each stroke. Due to the rising of the lever 97 and the bar 104 the bar 101 rises higher than the shoulder 106 on the lever 105. Should the separator disk 88 fail to place a thread in position to be taken by the needle, the spring 107 holds the lever 105 in such position that when the bar 101 descends it lands on the shoulder 106; and as the bar 104 continues to push against the forward wall of the notch 103 the needle completes its movement into thread-receiving position and the bar 101 fulcrums on the shoulder 106 sufficiently to raise the rear wall of the notch 103 clear of the bar 104, thus disconnecting the bar 101 from the actuating bar 104. When the separator disk 88 moves a thread into position to be taken by the needle, the lever 105 is swung clear of the bar 101, whereupon said bar drops into position to be engaged by the bar 104 upon the next forward movement of the latter. The rear end of the bar 101 is beveled as at 108 to allow the bar 104 to raise the bar 101 and enter the notch 103.

Fixed to the framework 95 is an arm 109 (Figs. 9 and 10) having a needle-receiving aperture 110 (Fig. 18), said aperture being open at 111 to permit the escape of the drawn-in thread. About the upper portion of the aperture 110 is a flaring guide 112 to direct the needle into the aperture 110 in case the operator, when selecting a harness eye, springs the needle aside from its true path. The forward portion of the arm 109 is in the form of a guard 113 (Figs. 10 and 18) to keep the heddles out of contact with the separator disk 88.

Rigid with the framework 95 is a tubular V guard 114 within which the forward end of the needle 94 reciprocates.

Assuming that the warp and the harnesses have been positioned in the machine in the manner hereinbefore described, and that the carriage 39 is at the left-hand side of the machine as represented in Fig. 3, the operation is as follows: Power is communicated to the mechanism by disengaging the looking lever 77 from the treadle arm 70. As the carriage 39 advances, the foremost warp threads are bowed outwardly by the disk 79, as shown in Fig. 10, such bowing causing the threads to be separated somewhat farther from one another than they were when extending directly between the bar 16 and the warp clamp. The selector takes the threads one by one in regular order and moves them into contact with the'edge of the separator disk 88, such movement of the selector being caused by the conjoint action of the lever 50 and the cam plate 86. The shoulders 89 on the separator disk move the selected threads into position to be taken by the needle. Before each thread reaches such position, the needle (which has passed through a heddle eye positionedby the operator) has reached its rearmost position as indicated in Fig. 15, so that the shoulder 89 of the separator disk places the thread in contact with the stem of the needle. In the ensuing forward stroke of the needle, the head 94 thereof causes thehead to bend as shown in Fig. 16, so that when the notch 94" comes into register with the thread, the latter springs into said notch as represented in Fig. 17. As the needle makes its forward stroke the thread is drawn in the form of a loop through the aperturellO (Fig. 18) and through the heddle eye, the threadbeing pulled out of the clamp 17-22. The oper- V the open side 111. The operator selects the heddle eyes in the desired sequence and positions them for the passage of the needle, the machine being driven atsuch a speed that the operator can select and position a heddle eye during the interval between the moment when the needle leaves the harness and the moment when it reenters the harness. In case the thread-selecting and separating mechanism should fail to place a thread in position to be received by the needle, the lever effects a suspension of the operation of the needle after the latter has reached the position shown in Figs. 9 and 15. WVhen the separator disk 88 moves a thread into position alongside the needle, the stop lever 105 is swung clear of the bar 101, thus permitting the needle to resume operation. Whenever desirable, the operator may suspend the operation of the machine byv depressing the treadle 69;

As threads are withdrawn from the warp clamp by the needle, the operator may, if

desired, from time to time adjust the weights 20 to lessen their effective weight or place more spring clamps 24: upon the portion of the warp clamp containing the unselected threads. Eventually, however, the levers 18 settle upon the stop pins 26. When all of the threads have been drawn in, the warp and the harnesses are removed from the machine and the carriage 39 returned to its initial position.

Such difference as there may be in the spread of the harnesses and the warp may be compensated for by sliding the harness-supporting bars 32 along the bar 30 to bring the foremost heddle eyes approximately opposite the foremost warp threads.

While the invention is herein shown as embodied in a warp-drawing machine, it will be apparent that various features thereof are capable of use in Warp-uniting, warpleasing and other types of warp-handling machines.
