21 Claims. 1

This invention pertains to improvements in automatic replenishing means for looms, and more specifically, to improvements in that part of the said mechanisms which function incidental to transfer of the filling supply from the battery to a shuttle, to the shuttle feeler and also to an improved and novel means for operating a thread cutter simultaneously therewith.

It is a general object of the invention to improve and to simplify that part of an automatic replenishing means for looms which functions in response to an indication taken from a substantially depleted filling carrier to set the transfer cycle in operation, to render such mechanism more certain in its operation and to simplify the installation and adjustment thereof so that when once properly set up, the mechanism shall maintain its adjustment and shall operate satisfactorily over a relatively great period of time.

It is a more specific object of the invention todevise a filling transfer mechanism which shall operate in response to an electrical signal conveyed through a circuit in which a filling feeler is adapted to indicate substantial exhaustion of the filling then being woven, and in which the major portion of the device is mechanical in nature and, therefore, very little load imposed upon the electrical portion of the device.

It is a further object of the invention to so simplify that part of the filling transferring means and of the protection devices functioning incidental thereto, and to consolidate them at the replenishing end of the loom, that it becomes unnecessary to provide the usual mechanical means at the left hand end of the loom and along the front portion thereof as has heretofore been the practice.

It is a further object of the invention to do away with the usual cam and slot actuating means and its attendant slackness and lack of precision and to substitute therefor a linkage comprised practically entirely of levers and interconnecting links all of which provide for positive actuation of the various parts involved with maintenance of precise tolerances of adjustment.

It is a further object of the invention to devise a replenishing and protection means in which the movements of the transfer latch, cutter and clamp and of the shuttle feeler are definitely interrelated and in which the adjustment or setting of each relatively to the other is maintained through positively interconnected linkage.

A further object is that of providing for the above mentioned interrelated parts a spring toggle means for temporarily holding them in extreme positions and for assisting in the movement of the parts from one position to the other.

Other objects of the invention will be apparent from the following more detailed disclosure.

According to the practice over a long period of time, automatic type looms or those which automatically replenish the supply of filling in the shuttle as the same becomes substantially depleted have been equipped with batteries containing a plurality of filling supplies which may be indexed or advanced in some satisfactory manner so that the supplies are successively transferred from the battery to the shuttle as the occasion requires. The condition of the filling has normally been sensed and indicated by a so-called filling feeler which has, in most instances, functionedthrough mechanical linkage to set in motion other mechanically functioning parts by which a transfer latch and other elements have been set to be actuated by a, bunter or other projection on the lay, so that the transfer cycle started as just above indicated, is completed upon the next forward movement of the lay. Briefly, the loom has means operable at that time to transfer the next succeeding filling supply to the shuttle and to eject the exhausted filling carrier, to interpose a shuttle feeler in the pathway of the shuttle, and to cause a cutter to part or sever the filling attached to the outgoing supply or carrier. While this mechanism has functioned more or less satisfactorily, all things considered, it has been desirable that it be simplified and that, if possible, the indication taken at one side of the loom by the filling feeler be transferred across to the replenishing side through an electric circuit thereby to make unnecessary all of the mechanical parts heretofore required for converting the movement of the filling feeler into a suitable mechanical impulse and carrying that impulse across the loom to set in operation the various instrumentalities to complete the cycle and which function at the opposite or replenishing side. It has also been desired to do away with certain cam means which have functioned at the replenishing side and which have been though to be more or less essential at least if suitable protection was to be provided, and with the slack movement resulting therefrom.

In carrying into effect the above mentioned objects and in obviating these and other difficulties, the impulse or indication derived from the filling feeler is transferred from that side of the loom across to the replenishing side through a circuit as hereinafter described in greater detail and functions through a solenoid or other similar electrical means to set or to change the r l ti Position of certain parts incidental to starting convenient manner.

:In' operation, the transfer mechanism func- 0 tion's a's replenishment is initiated "through a 'fe'el'e'r mechanism-preferably located 'at the op- "posite side of the .loom'and of a known type, p'referably "one in which exhaustion or near-exhaustion of'the filling supply completes "an elec- 25 tr ical circuit which in turn conducts power to energize an electrical means adjacent the reiplenishing 'side'of the machine. 'As the circuit is completed, the lay structure is employed for the' purpose of :moving certain parts to anex- 0 treme position whereupon thetransfer-may and will be effected if the shuttle "is properly :boxed; otherwise the protecting rmechanisrn will revoke the transfer returning all parts'to their original or inactive positions. Y p Y The protecting function is afforded by ashuttlefeeler 'generally'indicated by numeral 25 and comprising an angularly' formed member with parallelglower arms 25' pivoted at26 toxsome suitable supporting structure preferably attached to the loomsi de'or-other fixed part of the framework of the loom. The feeler terminates at its upper end, in a nose portion 'or active shuttle feeling elementj'l. When in the; position of Fig. .6, this shuttle :feeler will be engaged by the shuttle in the event thatelement is so misplaced or so incompletely boxed at the replenishing end pf the loom that the transfer .of 'a filling supply could not be-effected without danger of undesirable:Engagement and possible destruciqn .th -P i V Theshuttle feeler .is maintained in'either of its extreme pOsit'ions that of Fig. 5 or that of -Figs. 6 and v8, by a spring, toggle mechanism -coinprisinga compression-spring 28 surrounding a plunger 29 one end of which is pivoted -at 38 a t to the shuttle feeler =2 5 and the other end of which projects throughan opening in asleevel ke ta ne 13. wh ch ha r u c m large to aeccrnmodate a; substantial part r the .springitself.

. latch stand or holder 34 and is locked in position by lock nuts 35, one at either side of the stand 34. The stand 34 is so shaped as to provide an apertured pivot portion 36 through which pivot I9 is passed, also a downwardly projecting forked portion 31 to which is hinged an actuating arm 38, the latter being of angular form to extend back and downwardly to provide a second arm 39 to which is attached a spring 40 the opposite end of which is connected at 4! to a depending lug 42 at the rearmost end of the latch 33. That end of the latch is notched to be engaged by a hunter 43 attached to the lay structure, preferably to the beam or to the shuttle box at that end of the lay.

The arm 38 has a ledge 44, Fig. 4, which contacts against the lower side of the latch stand or holder 34. The spring 48 is under suflicient tension so that normally the latch finger 33 is maintained in such position relatively to the arm 38 that the ledge 44 is in actual contact with the lower surface of the stand 34 so that the finger and arm 38 normally tend to function as a unit. Downward pressure upon arm 38 tips the rearmost end of the finger 33 upwardly and the adjustment of parts is such that it stops in a position so that it will be engaged by the hunter 43 when the lay moves forwardly unless the transfer function is revoked as will hereinafter be explained.

The transfer latch mechanism is caused to function simultaneously with movement of the shuttle feeler by interconnecting mechanism which comprises a lever fixed to one end of a shaft 45 better shown in Fig. 2, and which is carried within bushings, one at either end of sleeve [3. This lever comprises a hub portion 46, Figs. 1, 3 and 6, fixed to the end of the shaft 45 by set screws or other suitable means and also two arms, one indicated by numeral 41 projecting rearwardly and the other 48 projecting forwardly and also outwardly toward the end of the loom. The first mentioned arm 47 is connected by an adjustable link 43 to a pivot 58 in a boss 5 I, Fig. 6, intermediate the ends of the shuttle feeler 25. Arm 48 connects by means of a link 52 to the forward end of arm 38, Fig. 1. This link 52 is forked at either end and is also adjustable, although it is to be understood that the actual form which the links 49 and 52 take may vary so long as they are suitably adapted to convey the movement of the shuttle feeler to the transfer latch mechanism, and vice versa.

fhe spring 40 functions in connection with the pivot between the stand 34 and arm 38 to permit a certain amount of articulation as is necessary when the transfer arm and hammer are actually moved to filling replenishing positions at which time the arm 48 moves upwardly along with a tendency for the latch finger 33 to move upwardly or at least, to remain at the elevation which it occupied when contacted by the hunter 43. Thus the movement of arm 48 moves lever 38 upwardly and the ledge or abutment 44 away from the lower surface of the stand 34 elongating spring 4| at that time.

For moving the shuttle feeler and the transfer latch to that extreme position which they occupy when transfer is about to be effected, a circuit is completed by a feeler 53, Fig. 9, and a solenoid 54 shown diagrammatically in Fig. 9 and also illustrated in Figs. 5 and 6, is energized so that the plunger or armature 55 is pulled upwardly to swing a bell crank lever having an arm 55 connected to armature 55 and a depending arm 51 atria in a direction to affect an electrically operated latch. In its free position the bell crank lever is held in place as a short projection 58 strikes a stop screw 59. The bell crank lever is pivoted at 69, a relatively fixed point with respect to the solenoid 54. When the feeler closes the circuit as just described, the parts move from the full. line to the dot-and-dash line position of Fig. 5,. and a wire bail 6| is then so set as to be engage-- able by a hook 32 attached to a holder or carrier 33 which is in turn fixed to part of the lay structure, more preferably, as herein illustrated, to the lay sword 24.

A cam lever having a depending arm 34 pivoted at 35 and having a cam 66 extending in the opposite direction carries the bail 6| which is fixed in the end of a small pivoting member 61 hinged at 53 at the lower end of the arm. A spring 65' tends to retain the arm and cam in inoperative position. A curved extension 63 of this bail holder is in a position to be contacted by the lower bevelled end E6 of the depending arm 51 of the bell crank lever which is actuated by the solenoid 54.

The cam 68 engages at the lower surface of one of the lower parallel arms 25' of shuttle feeler 25 and functions to move the parts to the opposite extreme position, that'illustrated in Fig. 6, preparatory to transfer. These arms 25' are interconnected by a connecting strut H. It is to be understood that the solenoid is energized when the shuttle is at the opposite end of the loom from that at which transfer occurs and that the bail is set in position to be engaged by hook 62 as the lay is in a forward position, rearward motion thereof functioning through hook 62 to pull the arm E54 in a rearward direction as shown in Fig. 6 whereupon cam 86 moving about pivot 65 pushes upwardly on lug H to raise the shuttle feeler so that the spring toggle mechanism passes its dead center position and then tends to move and to hold the shuttle feeler in active position, simultaneously moving the latch finger 33 to the position it occupies preparatory to transfer. A stop 12 in the form of an adjustable screw passing through lug i3 is set to be contacted by a projecting end 14 of the shuttle feeler thereby to limit the movement of the parts as illustrated in Fig. 6.

Now referring to Figs. 1 and 2, the cutter mechanism which may preferably be of the Stafford type is supported on a bracket fixed at the end of the sleeve 13. This sleeve is very rigidly supported in the hopper stand, or other fixed part of the rigid framework of the loom and the supporting bracket comprises a plurality of members which afford a certain amount of adjustment for positioning the cutter and for determining its pathway. These supporting members include a top stand indicated by numeral 15 and comprising; a central hub portion clamped by set screws orthe like to or adjacent the end of the sleeve and from which project arms one of which is drilled; for reception of a bolt or screw passing into a, depending member 18, and the other arm of which is slotted for a similar bolt or screwthreaded into the same depending member, but providing a certain amount of adjustment as described in Patent No. 2,223,896. An angular slide frame having vertical portion 71 and a horizontal part "i8 is likewise bolted to the depending member 76, the connection between the two providing for a certain amount of vertical movement. This horizontal portion 18 is grooved to provide a guideway within which a sliding, cutter supporting. plate 19 is movable to and from the lay structure so that a cutter generally indicatedby humeral ail-and carried by thesplate 19 may be moved toandifroma position to engage and sever the filling at the shuttlealll inthe manner understood by those skilled Lin-the art.

According to the particular construction which isnovel in theinstan't case,.the shaft 45 supported in bearings within sleeve LIB serves .a dual functionin that it imparts movement to the cutter or slide assembly by a link 83.

Themovableblademembers of the cutter are actuatedbyanarmts from which projects av pin -BB-engageable .with a .swivelli-ng cam generally indicatedby nu'meraltfiandpivoted at 81. The cam 86 isnormally disposed ina predetermined horizontal position by: a Ilug projecting therefrom and extending withina notch 88 to engage upon the-end of an adjustable stop screw 89 locked imposition in theusual .manner. This cam has an-upwardly turned, portion 90 at its forward end anda downwardly turned cam surface 9| directed toward thereanof the loom. When thecutter is iniinaetive position, Fig. 3, thecam 99 .is in the pathway .of .the pin jflisothat upon movement of the parts incidentalto initiating transfer, the. cam functionsithroughthe pinand arm 84 to open the blades of the .cutter .all.as illustrated in Fig. 1.

Spherical connections83 provide for free swivelling ofthe parts whichbecomesessential since thecutter s'lidesatan acute angle to the lay and toshaft 4'5, -while the.. plane ofmovement of arm 821s perpendicular thereto.

As above-described, the setting of the parts incidental-toeffecting transfer occurs during a rearward movement of the lay. .As .the'ilay .next

-movesv forwardly to complete transfer, the :con-

tact between hunter l3 and finger. 33 imparts the necessary motion to transfer arm I5 while another partiof .theflaystructure returns all other parts to .their initial and inactive position through itscontact withan adjustable contact .screw 92,IFig. .-1 lTI'hat causes thev cutter to move with layasitcu'ts and clampsthe "filling and the shuttlefeeler-and transfer l'a't'ch control parts to return toward their initial, positions. As soon .asthe spring toggle ipasses its center position it j hastens the return motion.

. Operation In operationofthe. device, it isto be assumed "that'the parts "are in position-as illustrated in :Fiigs: 3iand'fi. Upon sensing-nearexhaustion of fillingby the, feeler v53 the .circuit is closedso that solenoid .54 becomes "energized thereby pull- Ling upwardly on armature :55 to swing the bell crank lever comprising arms 56 andiilabout its pivot thereby to cam the'wire bail :6! upwardly to the ,dot-and dash line position 'of Fig. 5, this being effected -through the inclined interengayging surfaces of the end 10 of arm "57 and of the projectionfiflof the'holderforthe wire ball. This movement, just above described 'occursas' the lay is at about its forward position at beat-up and when the shuttle .is at'the "left'ghand end of the loom, or that end opposite the replenishing means. 7

Then upon the following rearward movement of the lay structure the .hookedien'd 62 of the projecting means attached "to-the lay structure which'engages bail 61 draws rearwardly onthat member to swing lever .54 about pivot '65 'so-that thecam 66 moves the shuttle feel'erZB about its pivot 26 and against theicompression of -the spring 28 at the toggle so :as "to set theishuttle feeler in the position illustrated in Fig. 6. ',Of course, just as soon as the spring toggle passes dead center positionwith respect to the pivots' 30 and 26, it. quickly moves thepartsthe remainder of the distance which they. maytraveLithat being governed by the stop 12 as his engaged by profjection .74, Fig. '6. There is a slight clearance 'between'the cam 66 and that 'partofthershuttle feeler which it engages when the parts have moved to extreme position in the direction of setting the parts in their operative position.

At the sametime that the shuttle feeler is moved .as .just above described, the transfer .latch is alsotmovedfromthe position of Fig.3 to that ofjFig. 1 'andthe'cutter likewise moved from the position of Fig. '3 to that illustrated in "the first figure. The-link 49, through the bell crank lever comprising arms 15'! and 28, functions at that time to push downwardly on link52 swinging the arm SBand the latch stand and transfer finger from the dot-and-dash line position of Fig. 'to a raised or elevated position in'which "the" notched end of the finger "33 is in position to be engaged by "the hunter 23 carried'by the lay mechanism upon the next forward'move- 'men'tthereof. At'that time the transfer latch *standand fingermove as a unit withthe-arm e'fl-since the spring 59 *main-tai-ns the-ledge 44in engagement with the'over-lying surface of the stand.

The cutter is "simultaneouslymovedforwardly to a position in which the blades thereof may engage the 'filling to -clamp-and cut it, through the interconnections comprising shaft tidand the depending arm 82 and link'-83. As that-cutteris -move'd forwardly, cam 86 functions as described to open the blades.

The parts are set to carry out the-transfer "function and that function will occur as the bun ter as contacts latch finger' 33 thereby pushing forwardly to swing the arm i8 about the *center or pivot'afforded by the'fixed sleeve 53 and to move the transfer arm and' har n-mer downwardly to project one-filling supply from the battery into the shuttle, thereby expeiling the carrier for-the-ex-pendedfilling. 'At-t'he same time, the shuttle feeler and-the cutter mechanism are moved toward their inactive positions as a part of the lay, or a hunter attached thereto, contacts the adjustable screw 92. Thus as the cutter is'moved forwardly as the lay advances, the arm't? swings shaft 45 so that the bell crank "lever carried at theoppos'it'e end thereof moves the shuttle feeler about its pivot 26 until the spring toggle which actually presented all the force holding the parts in position is moved to the opposite side of its dead center position whereupon it is then effective for quickly moving the elements to their initial or inactive positions, Figs. 3 and 5. It is to be understood that the hook 62 will have disengaged the bail 6| thereby permitting it to drop to its full line position, Fig. 5, and that as the shuttle feeler returns to inactive position, Fig. 5, the arm 64 and cam 66 will be returned to their initial position at which time the extension 69 will again engage behind the end 50 of the solenoid operated lever, the latter normally maintaining its initial or inactive position since the weight of the solenoid armature always tends to move it to the full line position, Figs. 5 and 6, in which the arm 58 engages the stop 59.

As the transfer is effected, the bunter 43 remains in engagement with the latch finger 33 until the lay actually starts to move rearwardly whereupon the parts then separate. It is also evident that the movement of the cutter and the shuttle feeler and all of the levers and links interconnecting these parts occurs first at a speed dependent upon the forward movement of the lay, and then when the spring toggle moves past its center position, at a more rapid speed. The arm 38, link 52 and the bell crank lever and link 49 therefore move independently of the transfer latch mechanism and the spring 40 becomes extended to a considerable extent at that time thereby to permit articulation of the arm and the transfer latch about the pivot between those members which may be considered a secondary pivot.

Cutting occurs at a position closely adjacent the most rearward extension of the cutter assembly or just as the lay contacting projecting screw 92 starts to move the slide 97 rearwardly at which time pin 85 rides up cam 9|. The cutter remains closed and retains the bound or clamped end of filling until it reaches its most forward position and, in fact, does not open until the next transfer movement is initiated.

In the event the shuttle is not properly boxed at the transfer, the tip 21 of the shuttle feeler engages the shuttle and as the lay moves forwardly, it pushes the feeler against the spring toggle to move the parts to their inactive position. The action is then one in which the bunter never engages latch finger 33 nor does the cutter engage the filling since these parts all move toward the front of the loom at a time earlier than The mechanism otherwise would be the case. becomes set for a second attempt to replenish as the filling feeler again the solenoid.
