The back wall or the casing this juxtaposed to one end face of the pockets 1 of "the endless conveyor fchain. the oppotened which pivots on an "upper and a lower hinge l4 and screws (Fig, 3)" insueha way thatthe pivotal lid, when in closed position, is placed at asmallr or greater distance from the open end of the casing 6.
On opening the pivotal lid 12 any emptypocketc 1 caneach be suppliedwith an empty'spool A which is insertable by hand into the pocket 1 it from the respective end face. The back wall of the casing 6 borders and determines atthe same time the depth of insertion-of the spools A unless the spools are pushed intothe-casinglfi by said lldup to the required depth, if necessary.

spools are arranged within the casing 6 inaplthird m- 1 machine is assumed to bea cop winding'machine By means of the hinge pins -I8,Flg. 3, the axis of hinging of the lid I2 is adjustable comment surate with the lengthbf thespools used in the By this means the empty propriate position for' being 'fed onward;
The pivotal lid Iris;advantageously,made-of transparent working material, to? exampleglass, thus permitting the irnmediatewiewing of'the emptyyspools A stored in the casing B; In the upperpart of the casing 6 a lateral opening" 16 serving as an exit from the pockets Tfor'the in t dividual' emptyspools A is providedfor passing the spools to the windingspindle 2 for the -purposeof being olampingly held to saidfspindle by means of a counter holder (ndtljfshdwn); in a manner known per se. This counter holder can be coaxially arranged with the winding spindle 2 by means of a supporting device and axially displaced against sprin influence.
On the termination of a winding on the spool clamped to the winding spindle 2 said spool is released, by automatic retraction of the counter holder, so-"ras' to fall"down. Thereupon, to; ,the winding spind1e2 a freshempty spool is supplied for which purpose the pocket chain 1, 8 is adwhich the two forked lever arms :25 convey the'I vanced the amount of the spacing of a pocket in 1 pocket chain 1, 8, into a position coaxially with which way each time a fresh empty spool is con-. veyed directly to the delivery position formed by I I the opening iii of the casing 6.
In the first embodiment shown in Figs". 1 to 3 on the upper bolt ll of the casing 6 two discs I! (Fig. 2) are secured which are interconnected by a group of four stop pins, that is, cross'pins l8 which are equally distributed on the circumfer lv ence of the disc 11 By this means a feed member is formed which is rigid: with the sprocket l and the cross pins l8 of which cooperate with a feed rod l8 which is pivotally connected with a control lever (Fig. 3), which, due to being spring-influenced bears againsta cam disc 22 by means of a roller 2 I, the camdisc rotating together with the driving shaft 4. I f
For the purpose of effecting the spool exchanging operation automatically the driving shaft 4 is advanced in a manner known per se at the end of each rotation after the winding of a spool is completed on the winding spindle 2, wherebythe feed rod I9 isreciprocated in its longitudinal direction from the cam disc viathe control'lever 2|]. By uide means (not shown) the lateral movement of the feedrod i9, is limited which rod moves, whenshifting in one direction of throw, the feed member [1,18 and thus the guide sprocket it) the amount of one,,quarter of a revolution by which means the pocket chain I, 8 .is advanced for one division. In the course of this operation'the feed rod 19 assumes temporarily a position, as shown in chain-dottedlines in Fig. V1, in which this rod engages with one of the cross pins 18.
In the. courseof each advance feed of the pocket 6 chain I, 8,: a:.-spring-pressed,locking lever 23,
which is fulcrumed on a" projection 24 on the casing 6 is: automatically positioned underneath a cross pin IE on the pair of discs l'l sothatthe pocket'chain is prevented from backward movement. By this meansithe precise feeding of the pocket chain 1, 8 step by step is warranted, which isparticularlyimportant insofar as the pocket chain 1, 8-tends to move ,backwardly when the chain length'shown on the righthand side in Fig.
1 outweighs that shown on the left hand sideby effect of theempty spools carried thereby. This happens obviously particularly :at the times when the left hand chain length is within the embrace of the'spooldelivery positionjfi.
From the pocketlof the pocket chain 1,, 8 arriving at the position ofdeliverylfi the empty spool'rolls away by action of its own weight so as to maintain a predetermined position, therolling having been imparted thereto by the V arcuate guide surface presentedto it, in order to' ibe properly received by two forked lever arms 25. The: forked lever arms 25 are mounted on supporting arms 26 which are extensible in the longitudinal direction by means of screws 21 relative to a mounting arm 28; By means of the mounting arms 28 the two supporting arms 26 are secured to a common shaft 29 whichhas its bearings 30 in the casing 6.;With anarm 3| fastened to the shaft 29 engages a connecting rod 32 which is articulated to a control lever 33 which, due to being spring-influenced bears, by means of a cam disc 35, against a roller 34, which rotates together with the driving shaft 4.
On each revolution of the driving shaft 4 the bearer arms 26, 28 are pivotally adjusted to the left in regard to Fig. 1 from the cam, disc 35 via the parts 34, 33, 32, 3| and 29,-in conjunction with empty spool, which had been received, while the preceding feed step had been effected by the 1 thewindingspindle 2 to which the spool is subsequentlyclamped by means of the counter holder, Thereupon the bearer arms 26, 28 swing back into initial position whilst the forked lever arms 25, as indicated in chaindotted lines in Fig. 1,
disengage from the clampingly fixed spool by wiping-across the latter. This effect is due to the forked lever arms 25 pivotally moving against the spring force of tension springs which normally hold the-forked lever arms 25'ina' predetermined position of rest relative to the supporting arms 26; The supporting arms 23 areaadjust able relativeto the mounting arms 28by means of the necte'd the 'upper end portion of which engages with a guide 40. on the gear box I and is provided withv a stop pin 4| for cooperation witlr'a' bellcrank lever 42' which is pivoted tothecasing Bat 43. The tripping rod '39 cooperating by means of the stop pinj4 l with the laterally directed arm of the "bell crank lever 42 has its second depending-arm formed as a locking pawl 44; i Y
As shown in Figs. 1 and 3 the locking pawl 44 projects into engagement with the lowerportion of a-bolt '45 on a pivotal bottom-of a box A! which is open on top and is secured the ca's ing 6 and serves for intercepting the full spool which had been released'from the windingspindie 2; The full spool received by the box: 41 drops out throughthelower end of the box into aremovable receptacle when the pivotal bottom 46 swings into the "chain-dotted position indicated in Fig. 1. This operation takes place automatically at predetermined times by, downward movement of the tripping rod 39 by action oflthe cam disc 36 through the intervention of the parts 31, 38, so that the bell. crank lever .42 ,is swung out by the stop pin 41 in suchmannerthatjthe locking, pawl 44 releases the bolt 45, whereupon the pivotal bottom 46 swings from its oblique'position about its axis 43$ downwardly until: it hits a bolt- 49 on the t'ripping rod 39. l Dueto the fact that the pivotal bottom.46, swings fromj closing position, 1 into positionfof maximum "opening of which the locking pawl .44 engages againwitli p p 2,878,978 the bolt' lso as a secure the pivotal bottom as in closing position again.
In the exemplificationiof the machine described the empty spool is conveyed towards the t winding spindle 2 from out of the stationary casing 6 including the pocket chain I, 8 by means of the pivotalfeeddevice composed of theparts25,
25,28 andZS. l In contrast therewith in the second exemplification the empty spool is supplied to the winding spindle 2.by the casing 6 itself, due to this casing, which contains thepocket chain I, 8 also in this case, -being swingably arranged. To this end the lower bearing bolt 5' serves as a pivot for shaft 4 (Fig52) as shownfor the first exemplification, while the automatic spool exchanging operation takes place. Inthe second exemplification two forked lever arms 53 are arranged, within the embrace of thespool deliveryposition it provided on the casing 6, in a manner similar to the arrangement of thetwo lever arms 25 used in the first exemplification. The lever arms 53 are mounted on a supporting member 54 which isadjustable. as to height relative to the casing 5 by means of a slot guideand cooperativescrews '55 in appropriate quirements.
position dependent upon re- The empty spool livery l6 ofthe casing 6 by means of the pocket chain 1, 8 isreceived by the two forked lever arms conveyed to the position of deto bear on the two legs forming the angular cross section of thetrough '51 by which means "the position :of the spool is definedn When the casing 5 for. the purpose of suppyling an empty spool to thewinding spindlez swings out of position of rest the trough 5] maintains its positiontrela'tive to the casing 6 by the pin .61 on the disc 60 sliding along the lower-longitudinal side of the stop lever Gil. 3 The casing 6 in swinging back into position or rest operates to movethe stud Glinto driving engagement with a mating rest 65 on the stop lever 63 in such manner that the pin BI is kept from movement by said rest 65 in consequence whereof the disc 60 turns about its axis,
thereby tilting thetrough 51; for thepurpose of delivering the full spool into a removable-receptacle; The tilting movement of the trough '51 is on the verge to come to an end if as shown in Fig. 6 the pin 62 on the disc 6| hits the stop lever '63, whereupon the lever 63 is raised in appropriate manner for permitting the pin 61 on the disc 60 to disengage from the rest 65 on the stop lever 63, andthen thetrough 51 is swung back into position of rest shown in Fig. 4 by action of the tension spring 84.
As evident from Fig.-7 theilower end of the casing 6 is equipped with a patterned cappiece B5 on the entrance side of the casing. This piece 65 is provided with a roundedout central recess 51 and two lateral recesses 68 arranged symmetrically thereto. The recesses 61 and 68 .are socoordinated in regard to position, form andsize.
with corresponding inserting positions within the range of the lower point of reversal of the endlesspocket chain that, as will be seen by comparison of Figs. 1 and 4, so to speak a guide is 53 "and inserted between the winding spindle and the counter holder (not shown) as the casing is 1 swung out of position of rest in order to be clamped in winding position. Thereupon the casing 6 swings back into position of rest in the course of whichmovementtheforked lever arms 53 wipe over the clamped spool, as indicated in chain-dottedlines in Fig. 4, by swinging about their pivot axes on the? supporting member 54 against spring influence. In the course of the swinging movementof the casing 6 intoinoperative position a control lever 56 mounted on the gear box I effects the feeding of the pocket chain obtainedwhich facilitates the insertion of empty spools into the chain. The cap piece 55 covers surfaces of the casing B onthe entrance side thereof thatcarry articulations through which the spool pockets are connected with; each other l, 8 by one division, due to the hook like end of the'feed lever 56 catching a cross pin H! on a feed disc" "so that the latter then rotates for one quarter of a revolution. When the casing 5 swings out of position of rest again another cross pin is on the feed lever II moves behind the hook like end of the control lever 56 for being caught by the latter for effecting afurther feed movement by the disc l1. and thus by the pocket chain 1, or one step.
Thefull spools being released from the windingspindle 2 in the coure of the spool exchanging operation are in this instance alternately intercepted by a trough 51 which has an angular cross section and. is mounted atits end faces by means of studs 58 on arrnsjof-a carrierstirrup 59 fastenedjto the casing One of the studs 58 carbox I. A tensionspring 64 tends to retain the trough 51 in the position of rest shown in Fig. 4
in which the trough '51 bears againstthe casing 6 by one of its longitudinal edges. 3 "The spool droppinginto thetrough?! in the upper endthereof.
by which means inadvertent inserting'oi spools between two adjacent pockets of the chain '1, 8 is practically made impossible. For the purpose of facilitatingin a, similar manner, the proper insertingof empty spools also within the embrace of. the upper'point of reversal of the endless pocket chain the casing including the pocket chain is provided with a correspondingly pat terned cap piece on the entrance side also at the The two guide prisms for the endless pocket chain may be dismountably arranged on their bearing bolts for allowing of being interchanged with other sprockets having different chain or pocket divisions if the pocket chain must be exchanged for another chain with corresponding divisions.
The spool magazine formed by the pocket chain, which servesat the same time as a conveyer, can naturally be built in any size as required.
Instead of forming an endless chain by articulating the spool pockets directly to each other the pockets may be arranged, upon choice, also on one or more chains. t
In the third exemplificationj shown in Fig. I a the horizontal spool pockets 1 are arranged in, an annular row about a horizontal axle 69. .The
spool pockets 1 are provided on the outside of a cylindricalliner m which is supported by the axle Bland is fed step by step so as to convey the pockets or empty spools successively to the position of delivery i6. An outer circumferential course of the spoolexchanging operation comes endless tapes, ropes or carrier ring H or the like retains the spools in thepockets.

' rier is secured'against backward movement by a. locking device ina =manner similarto that explained in connectionwith the two precedingly described exemplifications. Also in such arrangeev ments Walls may be. used as stop means for the end faces of the spools-as explained inthe two previous exemplifications. 1
It will be seen that, in general, the spool mag azine instead of being arranged on the righthand side of the windingspindle, that is the axis of said spindle, i shown m deal and 4., may date arranged on tile ieitiiandside er, if required,
directly above or below the axis of the winding spindle, that is, on the upper or under side of said spindle. In other words the spool magazine may be arranged in any desirecl,position, for example, laterally of the winding spindle on any side thereof or all around the same. For the purposes of the invention the mterstice between two adjacent spool pockets is kept as si'nallv as possible,
should be smaller than th clear xridth of a ocket.
