To all ywhom t may concern:

Be it known that I, JONAS NoRTHRoP, a citizen of the United States, residing at Hopedale, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Feeler-Looms; and I hereby declare the following to be a` full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to an improvenient in feeler looms and more particularly to an improvement in thread parting mechanism for severing the outgoing and incoming filling ends.

Automatic weft replenishing looms employed in weaving the higher grades of fabrics are provided with a filling feeler mechanism b v which the amount of filling on the bobbin in the active shuttle mayv be measured or determined.y and, when the filling has been unwound or exhausted to a predetermined extent, the filling feeler mechanism acts to set in operation the weft replenishing mechanism. Such looms are known as feeler looms. As theselooms are usually constructed the filling feeler mechanism is located on one side of' the loom and the weft replenishing mechanism on the other side of the loom, so that critical or predetermined exhaustion of filling is indicated on one beataip of' the lay and the weft or filling rel'ilenishing operation takes place on the next beat-up of the lay. Then the shuttle with its critically exhausted filling is boxed at the replenishing side of' the loom, it is customaryY to sever the filling and extending from the fell of the cloth to the shuttle (this filling end being known as the outgoing filling end) at about the time the replenishin;I operation takes place; and when the shuttle with its fresh supply of filling has continued the caving operation, it is customar;T to sever the filling end extending from the fell of' the cloth to the hopper (this filling end being known as the incoming filling endl. It sometimes happens after the determination of critical exhaustion of filling that the filling entirely unWinds from the bobbin before the shuttle is boxed at the replenishing side of the loom, so that a short weft is laid in the shed, that is, a mispick results and consequently a blemish appears in the cloth. One object of the present invention is to prevent the occurrence of the above-described mispick by producing a thread parting mechanism of' such construction that when the parting mechanism is brought into operation to sever the outgoing filling end, and the filling has become entirely exhausted after the indication of critical exhaustion and before the shuttle reaches the replenishing side of' the loom, the thread parting mechanism will act to set in operation devices for stopping the loom.

It sometimes happens during the weft replenishing operation that the filling is broken, that is, a hopper misthread occurs.` and the shuttle is picked to the opposite side of the loom Without paying out an intact filling. Occasionally the break in the filling is at such a distance from the bobbin that when the shuttle is boxed at the filling feeler side of the loom, a few inches of weft extend into the shed and form a mispick. Another object of the present invention is to prevent the occurrence of this mispick bv producing :i thread parting mechanism of such construction that. when the parting n'iechanism is brought into operation to sever the incoming filling end and there is no incoming filling end to sever. the stopping devices will be set in operation bv the thread pa rtiug mechanism to stop the loom.

A further object of the invention is to produce a thread parting mechanism having parter blades of such construction and arrangement that they coperatc with thc reed dents or with a similar structlu'c carried b v the lay, to sever the outgoing and incoming filling ends. The partei' blades are adapted to project through an)v part 0f the reed and to coperate with the adjacent reed dents; consequently, the thread parting mechanism may occupy any position longitudinally relatively to the lay. with the resuit that the same reed may be employed for the Weaving of all widths of cloth within the capacity of the reed. Whatever the width of the cloth woven.y the thread parting mechanism will be so positioned that the partei' blades will project through the reed immediately outside of the warp threads which are to form the selvage of the cloth. Inasmuch as the thread parting operation takes places only on the replenishing beat-up of the lay and on the beat-up of the lay inunediatcly following the replenishing operation, it is readily seen that the wear on the reed will be negligible. I believe 1 am the first to produce a thread parting mechanism having parter blades adapted to project through and to coperate with any section of the reed to perform the function of severing the filling. l am aware that hitherto thread parting mechanisms have been produced which have been adapted to project through the reed either with or without the removal of the reed dent-t` to perform the thread parting operation. but in these instances. so far as l am aware. the reed has not been used as one of the parting members.

l believe I am the first to produce a thread parting mechanism of such construction that when il is brought into operation to sever the filling` and no filling is present to be `severed. the loom stopping devices will be arti-'d upon by the thread parting mechanism to stop the loom.

To the accomplishment of these objects the invention resides in the improved thread parting mechanism hereinafter described and particularly pointed out in the appended claims.

ln the accompanying drawings illustrating the preferred form of the invention.` Figure 1 is a plan of a portion of the re.- plenishing side of the loom showing the improved thread parting mechanism thereon: Fig. 2 is a sectional side elevation of the parts illustrated in Fig. 1 showing the thread parting mechanism in normal or inoperative position. that is. in the position it occupies during the regular weaving operation of the loom: F ig. l is a similar view showing the positions of the parts of the thread parting mechanism after it has operated to sever the outgoing filling end: Fig. l is a similar view showing the positions of the parts of the thread parting mechanie-,m when the out going filling end has not been caught beteren the parler blades and the reed; Fig. 5 is a side elevation of a portion of the'parts of the thread parting mechanism showing their inter-relation when the lay is at its rear center: Fig. G is a detail showing the relative positions of the forward end of the release lever and its latch while the lay is at its rear center and the hopper arm has been moved to the right hy an actuation of the change shaft: Fig. T is a detail showing the inter-rclatimi of the forward end of the release lever and its latch while the lay is at its rear center and the change shaft has returned the hopper arm to normal position; Fig. 8 is an enlarged section showing the construction of the device for depressing the forward ends of the parter blades; and Fig. 9 is a diagrammatic view showing the interrelationship of the various parts of a feeler loom embodying the features of the present inA vention.

r1`he loom to which the improved thread parting n'iechanism is applied may be of any usual or preferred construction. The portion of the loom illustrated in the drawings comprises a lay l0 mounted on the lay swords 11 for oscillation toward and from the breast beam 12. A rock or change shaft 13 journaled in brackets secured to the front of the breast beam extends across the front of the loom.y is connected at one end ot the loom with the filling feeler mechanism. and is connected at the other end of the loom with the weft replenishing mechanism through a hopper arm 14. The change shaft l2?) with its connected mechanism constitute loom controlling devices. The plate 15 of the hopper.y which contains the supply of' filled bobbins, supports certain of the parts of the weft replenishing mechanism and is secured to a bracket 16 fastened lo the breast beam 12. Pivoted at 1T 011 the hopper plate 15 is the shuttle feeler 18 which is connected with the hopper arm 11 through a link 19 and a spring Q0. ldlhen the filling feeler mechanism indicates critical exhaustion of filling, it operates to impart an oscillatory movement in a clockwise direction to the change shaft 13 so to swing the arm 11 to the right, viewing Fig. whereupon the lower end of the shuttle feeler 18 swings to the left to feel for the shuttle 22 and determine whether it is proporly boxed for the replenishing operation. The shuttle travels across the lay on the shuttle race Q3 with its rear wall against the reed dents 21 of the reed 25. by which each weft is beaten up against the fell of the cloth on the forward beat of the lay. The above-described parts operate in substantially the same manner as corresponding parts on other filling feelcr controlled weft replenishing looms.

The improved thread parting mechanism comprises partei.' blades 28. the forward or filling engaging ends of which are adapted to pass between the reed dents and to project through the reed at all times whether the lay on its rear center or on its forward center and whether the partei' blades are in operative or in inoperative position. By reason of this arrangement the reed dents serve as guides for the partei' blades so that they shall not be injured during the oscillations of the lay toward and from the breast beam. The rear ends of the partei* blades are secured to a head 29 formed on the inner or parter blade end of an oscillatory parter rod 30 which is formed as a crank shaft, of which the middle section 31 serves as a crank pin by which an oscillatory movement is imparted to the rod 30 to depress or raise the forward ends of the parter blades to bring the parter teeth 32, which project downwardly toward the lay with their cutting edges toward the reed, either into operative or inoperative position respectively with relation to the filling. The outer end of the parter rod 30 is loosely received in a hole in the free end of an arm 33 adjustably secured to a support 34 disposed in substantial parallelism to the parter rod 30. The support 34 is secured by a bolt and slot connection to a bracket 35, in turn secured by another bolt and slot connection to a second bracket 36 fastened to the frame of the loom. By means of these bolt and slot Connections the position of the partei' blades 2S may be adjusted longitudinally of the lay. By moving the support 34 longitudinally the partcr blades 28 may be brought into position to coperate with any desired part of the reed according to the width of the cloth being woven. The end of the rod 30 nearest the parter blades is received. not only for oscillatory movements but also for short reciprocatory movements toward and from the breast beam, in a horizontal slot formed in a boss 37 on the support 34. During the weaving operation of the loom the forward ends of the parter blades are in raised position near the reed cap or upper rail 38 of the reed frame, so as to be ont of the path of motion of the shuttle as it is picked across the lay. The parter blades are maintained in this position during the weaving operation by the engagement of a cam surface 39 with the crank pin 31, the cam 39 serving to depress the pin 31 and thereby raise the parter teeth 32 above the filling. The cam 39 is formed on the under side of a parter blade controller 40 provided at its rear end with. a slot 41 which engages a pin 42, by which the rear end of the controller is supported` projecting laterally from a forward extension 43 of the bracket By means of this construction the blade controller may be moved toward and from the breast beam. When the blade controller 40 is in normal position. as shown in Fig. 2, the forward end of the slot 41 is against the pin 42 which acts as a stop pin to limit the rearward movement of the controller. and the cam 39 presses downwardly against the crank pin 31. The blade controller 40 is moved into and held in this position by means of a tension spring 45, the forward end of which is secured to the forward end of the contro-ller and the rear end of which is secured to a pin fixed in the extension 43. The blade controller is moved toward the breast beam to release the rod 30, and permit the thread cutting teeth 32 of the parter blades to descend into operative position in front of the filling. This forward movement of the blade controller is effected by the engagement of a hook 46 formed on the forward end of the controller with a bunter 47 secured to a plate 48 forming part of the shuttle box at the replenishing end of the lay. The blade controller hook 46 is maintained above the path of motion of the bunter 47 during the weaving operation by the engagement of a cam slot 5l, formed in and near the rear end of a release lever 53 pivoted at its rear end on the pin 42, with a pin 50 projecting laterally from the blade controller. The forward end of the release lever 53 is held in raised position by a shoulder 54 formed on the lower end of a latch lever 55 pivoted at 56 on a bracket 57 adjustably secured to the upper end of the hopper arm 14, so as to hold the forward end of the blade controller above the path of motion of the bunter 47. A torsion spring 58 tends to swing the lower end of the latch lever 55 rearwardly toward the forward end of the release lever 53. The rearward movement of the latch lever is limited by a stop shoulder 59 which comes into engagement with the forward side of the bracket 57.

lVhen the filling feeler mechanism indicates critical exhaustion of filling and the hopper arm 14 swings to the right and thereby disengages the latch lever shoulder 54 from the forward end of the release lever 53, the forward end of the release lever, acted upon by gravity, descends until the stop lug 60 rests on the base of the bracket 16. as shown in Fig. 6. As the forward end of the release lever descends, the upper side of the slot 51 by pressing against the pin 50 depresses the hook 46 into the path of motion of the bunter 47, the stop lug 60 determining the lowered position of the hook 46; whereupon as the lay moves forwardly the blade controller 40 is carried toward the breast beam, as shown in Figs. 3 and 4, thereby releasing the crank pin 31. The release of the crank pin 31 permits a spring pressed slide 61` in the lower end of which thc crank pin is loosely received, to raise the crank pin and thereby impart an oscillatory movement tothe outer ends of the parter rod 30 so as to depress the parter teeth 32 of the parter blades toward the shuttle race. The slide 6l is received for vertical movements in a slide-way formed between a guide 62 and the extension 43. The guide 62 is adjustably secured to the extension 43 by means of a screw 63. A compression spring 64 interposed between a rib 65 of the slide 61 and a part of the guide 62 tends to impart an upward movement to the slide 61. The limit of upward movement of the slide 6l and consci-,uently the amount of downward movement of the forward ends of the parter blades. is determined by the engagement of the upper sideof the rib 65 with a pin 6C secured in the extension 43.

Vilhile the hopper arm 14 was swinging to the right as a result of the indication of critical exhaustion of the filling, and while the latch shoulder 54 was moving out from under the forward end of the release lever 53, thereby permitting it to descend under the action of gravity and carry downward with it. by the pressure of the upper side of the slot 51 on the pin 50, the forward end of the blade controller 40 so as to depress the hook 46 in the path of the bunter 47, the lay was on its backward beat and the shuttle was picked to the replenishing side of the loom. The depression of the hook 46 into the path of the bunter 47 did not release the cam 39 from engagement with the crank pin 31, so that the forward ends of the parter blades :28 remained in raised position. During the next forward beat of the lay after critical exhaustion of filling, this being the replenishing beat-up of the lay, the bunter 47 engages the hook 46 of the blade controller 40 and pulls it toward the breast beam, thereby disengaging the cam 39 from the crank pin 31 and permitting the springpressed slide 6l to raise the crank pin Si and oscillate the parter rod 30 to depress the teeth 32 of the parter blades toward the shuttle race and in front of the filling. lt is assumed that, after critical exhaustion of filling was indicated by the filling feeler mechanism, enough filling remained on the bobbin to suflice for the pick of the shuttle to the replenishing side of the loom and that, therefore, a lling thread was laid in the shed, so that, as the lay moves forward on the replenishing beat-up, the cutting edges of the parter teeth 32 engage the filling and present it to the forwardly moving reed dents 24.; whereupon, owing to the continued forward movement of the lay and of the reed dents, the filling is severed between the cutting edges of the parter teeth and the reed dents. Inasmuch the replenishing operation is completed b v the time the lay reaches its forward center, it will be observed from an inspection of Fig. 3 that the thread parting operation takes place slightly before the completion of the replcnishing operation, that the thread parting operation takes place about the time the warps are crossing each other for the next shedding. lWhile the lay was on its replenishing beat-up and the blade controller 40 was being carried forward owing to the engagement of the bunter 47 with the hook 46, the pin 50, carried by the controller 40, acted upon the upper side of the cam slot 51 formed in the release lever and lifted the forward end of the release lever 53 into position to permit the latch lever shoulder 54 to swing under it, as shown in Figs. 3 and 4. At this time, however, the hopper arm 14 was still to the right. Upon the first return or backward beat of the lay after the replenishing operation and the consequent disengagement of the bunter 4T from the hook 46, the spring 45 acting upon the blade controller 40 draws the blade Con troller rearwardly as the lay beats back, thereby permitting the forward end ofthe release lever 53 to descend before the latch shoulder 54 has had opportunity to swing under it. By the time the lay has reached its rear center the hopper arm 14 has swung to the left toward the breast beam, bringing the rear side of the shoulder 54 into engage ment with the forward end of the release lever, the spring 58 permitting the latch lever 55 to yield slightly, as shown in Fig. 7.

The assumption is that during the replenishing operation no mishap occurred and, eonscrpiently, on the first pick of the shuttle an ay from the replenishing side of the loom an intact filling was laid in the shed. On the first beat-up of the lay following the replenishingoperation, the parts of the thread parting mechanism being in the same position in which they were in on the replenishing beat-up of the lay, the engagement of the bunter 4T with the hook 46 acts to release the cam 39 from the crank pin 3l to permit the slide 6l to depress the partei' teeth 32 toward the shuttle race,so that they may present the filling to the forwa-rd movement of the reed dents 24. As the lay completes its forward beat. the filling is severed in the same Inanncr as before. This forward beat of the lay resulted, as before, in the raising of the forward end of the release lever 53, where'- upon the latch lever under the actuation of its spring 58 swings the shoulder 54 under the forward end of the release lever, so as thereby to hohl it and the forward end of the blade controller in a raised or inoperative position. All the parts of the thread parting mechanism are now in their normal or inoperative position, as shown in Fig. 2. and remain in this position until critical'exhauslion of filling is again vindicated by the v{illing feeler mechanism. lt is thus seen that the outgoing filling end is severed on the rcplenishing beat-up of the lay and the inA coming filling end severed on the first beatup of the lay following replenishment, and. consequently, this latter filling end is severed before it has had opportunity to break and snap into the shed. Thus, one canse of double picks. that is, thc laying of lwc wefts in one shed. is eliminated.

lf. after the determination of critical eX- haustion of filling. it should happen that the filling should entirely unwind and exhaust the bobbin before the shuttle reaches the replenishing side of the loom, a short weft would be laid in the shed causing amispick, and so means are provided to stop the loom, to permit the operator to pick out the short weft. Then the partei' blades '28 are depressed toward the shuttle race and they do not present any filling to the reed dents 24, the thread parting mechanism operates to cause loom stoppage. The connections between the thread parting mechanism and the loom stopping devices comprise a U- shaped stop controller (5S) of which the rear ends are received in collars 71 secured to a pivot pin 72 journaled in the upper arm 73 of a stop lever T4 fulcrnmcd at 75 on the loom frame. A link 7G connects the lower arm of the stop lever 74 with the free end of an arm 77 secured to a stop shaft 78 connected with the usual means for stopping the loom. These parts constitute loom stopping devices. A compression spring '79 interposed between a lug on the loom frame and the forward side of the upper arm 73 of the stop lever 74 tends to swing the upper arm of the lever 74 to the left and the lower arm of the lever 74 and arm 77 to the right, viewing Fig. 2. The extent of these movements is limited by the upper end of the stop lever coming into Contact with the loom frame.

0n a framework 80 rising upwardly from the lay is secured an actuator 81 having a barb 8:2 for engaging the cross-bar 70 of the stop controller. so as thereby to actuate the loom stopping devices. lWhen the cross-bar is permitted to be engaged by the barb 82 on the forward boat of the lay. the cone tinued forward motion of the lay and of the actuator 81 draws the cross-bar 70 forward and oscillates the stop lever 74 on its pivot 75 in a clockwise direction, thereby swinging the lower arm of the lever 7l to thc left and through the link 76 and the arm TT. oscillating thc stop shaft 78 in a clockwise direction to release the shipper or other stopping means and stop the loom. The cross-bar 70 of the St op controller 69 is maintained during the weaving operation in the upper end of an obliquely disposed cam slot 84 formed in a cam piece 85 secured by a bolt 86 to a lug 87 projecting upwardly from the blade controller 40. It will be observed. therefore, from an inspection of Fig. i), that during the regular weaving operation of the loom the cross-bar of the stop con troller 69 is above the path of motion of the barb 82 of the stop actuator 81.

Upon an oscillation of the change shaft 137 resulting from the indication of critical exhaustion of lillin and the consequent forward movement o the blade controller 40 and the cam piece 85, the upper side of the cam slot 84 by acting upon the cross-bar 70 causes it to descend to the mouth of the slot 84, in which position it is in the path of the barb 82. By means of the cam slot 84 the cross-bar 70 positively and rapidly moved from its inoperative position above the path of the actuator 81 into the path of the actuator. Thus the uncertainty of gravity action is eliminated. At this time the barb 82 is somewhat. to the rear of the cross-bar 70 and the cutting edges of the partei' teeth 322 are in front of and distant from the reed dents about the thickness of a filling thread. lf now, there is fillingl between the cutting edges of the partei' teeth 3:2 and the dents 24. this filling will be of sufiicicnt strength, whatever its Hoeness, to cause the parter blades to be drawn forward with the lay until the partei' end of the rod 3() is drawn to the forward end of the .slot formed in the boss 37. As the parter end of the rod 3() moves forward it carries with it a link 89 of which the forward end embraces the crank pin 31, and the rear end is loosely received in a .hole in the lower end of an arm 9() depending from the pivot pin 72, whereupon check nuts 91 threaded on the free end of the link 8S) pressing against the rear side of the lower end of the arm 90 carry it forward and oscillate the pivot pin 72, thereby swinging the cross-bar 70 of the stop controller 69 npwardly clear of the path of motion of the barb 82. Thereupon, the lay and the stop actuator complete their forward movement without affecting thc loom stopping devices. lf. however. no filling was caught between the cutting edges of the parter teeth and the reed dents 24. the partcr end of the rod 30 would not be drawn forward, the link 89 and the arm 90 would remain quiescent, and the cross-bar 70 of the stop controller would remain in the path of the barb 82. so that. as the la).y continued its forward movement, the barb 82 would engage the cross-bar 70, thereby swinging the stop lever 74 about its pivot and imparting an actuation to the stop shaft 78; whereupon the loom would be stopped. 'lhus it is seen that if the crossbar 70 of the stop controller G9 is permitted to remain in lowered position. it indicates that fillingr is absent and that the loom should be stopped. And conversely. if the cross-bar 70 is swung upwardly clear of the barb 82, it indicates the presence of filling at the time of the thread parting operation.

ln order that the forward ends of the parter blades 28 may be raised clear of the path of motion of the shuttle on the backward beat of the lay after the thread parting' operation.` the stop actuator 81 is provided with a cam surface 93 which, as the lay beats backward, comes into engagement with the crank pin 31 and depresses it, thereby raising the forward ends of the parter blades 28 above the path of motion of the shuttle. The arrangement of these parts and the timing of their operation are such that before the shuttle passes the place occupied by the parter blades, the cam shoulder 93 engages the crank pin 31 so as to lift the forward ends of the parter blades above the shuttle and then, as the lay continues its backward beat, the spring 45, acting upon the blade controller 40, brings the cam surface 39 into engagement with the crank pin 31 and, consequently, the forward ends of the parter blades are continued in their raised position during the backward beat of the lay.

It will be observed from an inspection of Fig. 2 that during the normal operation of the loom and the retention of the crossbar T0 of the stop controller 69 in the upper end of' the cam slot 84 a space separates the rear side of the lower end of the arm 90 and the check nuts 91. This space corresponds to the drop between the upper and lower ends of the cam slot 84, so that, after the actuation of the change shaft 13 and the swing of the hopper arm 14 to the right, and the consequent forward movement of the blade controller 40 and the cam piece 85, the passing of the cross-bar 70 into the mouth of the cam slot 84 serves to bring the rear side of the lower end of the arm 90 against the check nuts 91, so that the slightest force exerted upon the parter end of the rod 30 in the direction of the breast beam serves to tilt the stop controller 69 on its fulcrum. In this connection it will be observed that the stop controller 69, the link S9 and the parter rod 30 are of very light construction so that they respond readily to the slight forward movement of the par ter blades 28 when the cutting edges of the partei' teeth present the filling to the severing action of the reed dents 24.

ln the foregoing description of the specific embodiment of the present invention, the features of the invention have been described as cooperating to sever the outgoing` and incoming filling ends on a feeler con trolled` weft replenishing loom, and if these filling ends are not present. to stop the loom, The thread parting mechanism has been described as being set in operation by a turning of the change shaft connected with the filling feeler mechanism. 1t will be understood. however, that the invention is not limited to application to feeler controlled, automatic weft replenishing looms, but is also adapted for application to other types of :infomatie weft replenishing looms as, for example, those which are controlled by a filling detector mechanism connected with tbe change shaft. In case the invention is applied to a filling detector controlled, automatic loom, the thread parting mechanism would of course be employed only to sever the incoming filling end, inasmuch as there would be no outgoing filling end. In this case the thread parting mechanism would not be employed to stop the loom on filling absence, but the loom would be stopped through the action of the filling detector in the usual manner.
