19 Claims.

This invention relates to fastening inserting machines, and is illustrated herein as embodied in a heel seat lasting machine of the type disclosed in United States Letters Patent No. 2,420,290, granted May 13, 1947, upon the application ofAugustus D. Willhauck, and adapted to secure a shoe upper in lasted relation to a shoe bottom member, such as an insole, by means of fiber pegs successively severed from strands of fiber fastening material. In machines of this type, the strand or strands of fastening material are usually supplied from a reel or reels, on which the strands are coiled up, by means of a strand feeding mechanism which serves to advance the strand or strands intermittently into a strand severing mechanism in which the fastenings, such as pegs, are severed from the strand or strands.

It is an object of the invention to provide an improved strand feeding mechanism so designed that it will insure the delivery of predetermined, uniform lengths of strand material to the strand severing mechanism without undue strain on the feeding mechanism and without excessive strand tension, liable to cause strand breakages, even though the feeding mechanism is called upon to handle simultaneously a plurality of strands, in the present example up to twenty-two strands. It is a further object of the invention to provide mechanism whereby on strand failure, i. e. strand breakage or exhaustion of strand supply, the strand feeding mechanism and other operating mechanism of the illustrated machine, such as mechanism for operating a work supporting jack, are rendered inoperative. This will prevent continued operation of the machine with less than the required number of strands presented to the strand severing and peg forming mechanism until the faulty situation has been remedied. Moreover, it is a still further object of the invention to provide mechanism operable at the will of the operator to prevent the operation of the strand feeding mechanism and fastening inserting mechanism but permit the operation of the jack actuating mechanism if, for test purposes, the illustrated machine is to run with a work piece presented thereto on the jack but without the forming and driving of fastenings.

To this end and in accordance with one feature of the invention there is provided in the illustrated machine a strand pull-off member operatively connected with the strand feeding mechanism in such a way that, on completion of a strand feeding operation, the pull-ofi member is caused to pull off a length of strand from the supply and to hold that length of strand taut between the supply and the feeding mechanism. Immediately prior to the commencement of a strand feeding operation, the pull-off member is caused to slacken the extent of strand or strands between the supply and the feeding mechanism thus greatly facilitating the operation of the latter and reducing strand breakages to a minimum.

In accordance with another feature of the invention, each strand is engaged by a springbiasecl feeler which is held, by its engagement with the strand, in a normal operative position against the tension of its spring. On strand failure this feeler is adapted to act on a contact member connected to a throw-out mechanism by means of which the feed mechanism and the jack mechanism may be rendered inoperative.

In order to determine the accuracy of the position of the work piece with relation to the operating instrumentalities of the machine that act upon the work piece, it is sometimes desired to run the machine with the jack presenting the work piece in operative position but without the forming and driving of fastenings. Accordingly, the invention provides a manually controlled mechanism by means of which the jack mechanism may be disconnected from the above-mentioned throw-out member, and the throw-out member rendered operative only to stop the feeding mechanism and the fastening inserting mechanism.

These and other features of the invention will now be described in detail in connection with the drawings and will be pointed out in the appended claims.

As has been stated, the invention is illustrated herein as'embodied in a heel-seat lasting machine ofthe type disclosed in the above-mentioned patent. Accordingly, only so much of the general organization and-construction of that machine-will be shown anddescribed herein as it is necessary to refer tolfo-r an understanding of this invention. Ithas also been explained that the machine referred. to-is adapted to insert into the work presented thereto fastenings in the form of peg-s which are formed in the machine from strandsof fastening material, for example, fiber strands S. Thus, the illustrated machine, the same asthe machine in the patent referred to, has: a strand supply generally indicated at A in Figs. 1 and 2, astrand-f'eeding mechanism generally indicated at B in Figs. 1 to 4, a strand severing and peg transferring mechanism (not shown), peg inserting mechanism (not shown), a jack, generally indic'atedat C in Fig. 14 adapted to-support a shoelast and a shoe mounted thereon, anda jack controlling mechanism, generally indicated at D in Figs. 14 and 15, adapted to control the movements of thejack into and out of operative position. In its operative position the jack presents the heel seat portion of the shoe to the lasting mechanism (not shown), the latter mechanism including wipers and a heel end clamping band.

The illustrated machineis equipped to process simultaneously up to twenty-two fiber strands for the simultaneous insertion into the heel seat portion of the shoe of up to twenty-two fiber pegs'severed from the strands. Thus, the strand supply A of the illustrated machine comprises twenty-two reels, indicated at 23 in Figs. 1 to 4. Only eleven reels are shown in Fig. 1, the other eleven reels being located behind the reels shown in that figure. Each reel carries a coil of fastening material. To support the reels in the machine, the machine frame 22 is provided with two uprights 24 connected together by a horizontal'bar 26 extending through brackets 28 secured to the uprights. Similar brackets 3B are carried in uniformly spaced relation on the bar 25 and each bracket 28, 30, with the exception of the. bracket 28 at the extreme right of Fig. 1, has two extensions or arms 32, on each of which two reels are rotatably mounted in side by side relation. The just-mentioned bracket 28 at the extreme right of Fig. 1 has three extensions or arms 32 and. thus carries six reels 20. The strands of fastening material run through suitable guiding 4 eyes 34 secured to th brackets 28, 3B and from there run toward the front of the machine. The entire strand supply is protected against dirt and other foreign matter that otherwise might drop into it by a cover 36 mounted on the upper ends of the uprights 24.

The mechanism proper for feeding the fiber strands which is illustrated best in Figs. 3 and 4 is substantially the same as the strand feeding mechanism of the machine disclosed in the abovementioned patent. Briefly, the illustrated strand feeding mechanism comprises a feed roller 38 and a cooperating pressure roller 40, between which rollers the twentytwo strands of fastening material' pass and which serve intermittently to ad- Vance the strands into the strand severing mechanism of the-machine. The feed roller :38 is preferably a solid unyieldable member provided with twenty-two grooves adapted to receive the twenty-two strands, whereas the pressure roller it ismadeofa yielding materiahsuch as rubber. The feed roller 38 -is securedon a. shaft 42 rotat-v ably mounted in a. bracket 46'. secured to'the machine frame. Thereare. mounted on the shaft 42,. as fully disclosed inxthe patent". referredto, two oppositely operating Horton. clutches. 'I heouter driving sleeveof the first clutch is indicated at 46V in Figs. 2', 3 and s and; as willnbe'. described, it is oscillated so as to impart to the shaft 42 and the feed roller Bean intermittent: rotation in one-and: the same direction. The second :I-Iortonfclutch, as also fully disclosed in the. patent referred to, merely serves to lockithe shaft onreverse rota-2 tion of the sleeve flt'of the. first clutch by the: driving. mechanism to. bedescribed.

The pressure roller is is secur d one shaft 4'8 rotatably mounted inz-a swingableframe .or bracket 58. Gearing 49 (Fig. 2")? isprovid'ed to transmit thev rotation of. the. shaft: 42 tot-the shaft 48,. the arrangement beingsuch that. the two rollers 38 and f-t rotate at ab'out 'the same peripheral speed. The bracket-ED tFigs': 2 ,-3-and 4) is hinged" on a shaft 52 which -iissecured in the lo wer-end of the bracket 44 Ja -coupling pin 5% is pivotally mounted on a'shaft 5fsecured in the upper portion of the bracket 44 and normally lies in a grooved portion providedi-n the upper end of the bracket 50 and is held -inthat position b -a thumb; nut 58 threaded ontothe pin and abutting the racket 59; Thus; the pressure of the roller 40- against the-ro-ller may be adjusted by the ma nipulation of the thumb-nut 58.

The already-mentionedmechanism for actuating the strand feeding mechanism will now bedescribed. The above-mentioned outer driving sleeve 56 of the first I-Iortoncl-utch has a lug 60' (Figs. 3 and 4) with which is pivotally connected the forward end of a reciprocatingactuating member in the form of a link 62". The link 52' carries at its rearward end a headedpi-n 54, the head of which is held in a T-shaped guideway 66 provided in a substantiallyvertical rocking lever 68. As wi-ll be describedfthe pin 34 is adjustable along thegui'deway BG-so-asto vary the length of feed movement imparted to the strands- S. The lever tfl'issecuredto a shaft l-t rotatably mounted in a lug 12 provided on the machineframe 22. Threaded onto the pi-n Edie-a thumb nut 14 by means of which the-pin (it may be caused to bind in the guideway SEE-and thus tomaintain its position of adjustment" therein. On the other hand; uponloosening the thumb nut 14 the pin 64 may be adjusted along the guideway 66 with relation to the shaft- 16, thereby varying the effective length of the rocking lever- 68 and thus the throw of the link 62 and consequently the length of feed movement imparted to the strands S.

For the purpose of rocking the lever 68 there is pivotally secured to it at I8 2. driving rod I (Figs. 1, 3 and 4). The rearward end portion of the driving rod I6 is threaded into a turn buckle 80, through the other end of which there is slidable a rod 82. A spring 84 is mounted on the rod 82 between a fixed collar 86 and the turn' buckle 80 and serves to transmit the motion of the rod 82 toward the right of Fig. 1 to the driving rod I6. As in the machine of the abovementioned-patent, the rod 82 is actuated by a bell-crank lever 88 pivotally secured on the machine frame and connected by means of a vertical rod 90 to a slide (not shown) which is mounted for reciprocation in the machineframe and which is provided with a cam follower (not shown), the cam follower being actuated by a cam (not shown) mounted upon the drive shaft (not shown) of the machine. As will be seen, reciprocation of the rod 90 causes reciprocation of the rod I6 to actuate the above-described strand feeding mechanism. The length of feed movement imparted to the strands S may be regulated by adjusting the headed pin 64 along the guideway 60 as described. The strands after leaving the feed roller 38 and pressure roller 40 are received in guiding tubes 92 which conduct the strands into the above-mentioned strand severing and peg transferring mechanism.

To assist the above-described strand feeding mechanism in its operation there is provided a pull-off mechanism illustrated best in Figs. 3 and 4. The pull-off mechanism comprises a pulloff roller 94 over which the twenty-two strands S of fastening material pass. The roller 94 engages the strands at a location between the strand supply or reels 20 and the strand feeding mechanism, in particular, the

rolls

38 and 40. The pull-off roller 94 is mounted on a movable support in the form of an arm 96 which is pivotally secured at 98 to the bracket 28 at the extreme right of Fig. 1. The free end of the arm 96 is forked and has pivotally secured thereto a trunnion block I00 which is bored vertically to receive a, rod I02 held in position by a nut I04 engaging the upper extremity of the rod and resting against the top face of the trunnion block. The nut I04 is secured against rotation by a lock nut I06. The rod I02 is pivotally secured at its lower end to an arm I08 which is secured upon a shaft I I0 mounted for rotation in a bracket I I2 secured to the machine frame. A spring H4 is mounted on the rod I02. The upper end of the spring I I4 abuts the trunnion block I00 and its lower end rests against a washer IIB held on the rod I02 by nuts IIB. It will be seen, therefore, that the spring II4 normally serves to maintain the pulloff roller 94 yieldingly in its uppermost position in which the roller 94 holds taut the extents of fiber strands between the strand supply and the strand feedin mechanism. Secured to the shaft H0 is also a rearwardly extending arm I20 which is pivotally connected to a downwardly extending link I22. The link I22 is pivotally connected to a lug I24 which is part of the outer driving member 40 of the above-mentioned first Horton clutch on the shaft 42 of the strand feeding mechanism. The arrangement is such that on forward movement of the above-mentioned reciprocating link 62, during which the feed roller 38 is rotated to advance the fiber strands,

the just-mentioned lug I24 is rotated in a clock-- wise direction, as viewed in Figs. 3 and 4, with the result that the link I22 is elevated. The shaft H0 is rotated in a clockwise direction, as viewed in Fig. 3, by reason of the rotation of the arm I20 in the same direction due to the elevation of the link I22. This, of course, also causes a clockwise rotation of the arm I08 as a result of which the rod I02 is lowered, thereby positively lowering, through the agency of the nut I04 and trunnion block I00, the pull-off roller 94. In consequence of the lowering of the pull-off roller 94 the extents of fiber strands between the strand supply and the strand feeding mechanism are slackened. Thus, the task of the strand feeding mechanism in advancing the twenty-two fiber strands is considerably facilitated and the danger of strand breakage, imminent by the sudden application of considerable tension to the fiber strand, is mitigated. As pointed out, the slackening of the strands by the pull-off mechanism occurs simultaneously with the beginning of the strand feeding operation. If after a feeding operation the link 62 is returned toward the left of Fig. 3 into its initial position the lug I24 is rotated in a counter-clockwise direction with the result that the shaft H0 is rotated in a counterclockwise direction elevating the rod I02 and collar IIB secured thereon, as a result of which elevation the pull-off roller 94 is yieldingly moved back into its uppermost position through the agency of the spring H4. The timing of these movements is such that the slackening of the strands by the pull-off mechanism occurs quickly and that the actual strand feeding operation also only occupies. a minor portion of one cycle of operations of the machine. On the other hand, however, the return of the pull-01f roller 94 into its initial strand tensioning position consumes a considerable 'portion of a cycle of operations. During this return of the pull-off roller 94 into its initial position it causes a new extent of strand or strands to be pulled off the reels 2!] relatively slowly and this new extent of strand is, so to speak, held in readiness by the pull-off member 94 for the next strand feeding operation. Accordingly, the strand feeding mechanism proper is relieved from the task of actually pulling the strands off of the reels. As stated, the pulling off is effected by the roller 94 in a manner much slower than could be effected by the strand feeding mechanism, thus also preventing the reels 20 from overturning in which case too much strand would be unreeled.

It nevertheless may occur from time to time that one or several of the twenty-two strands will break. Moreover, it may happen that the coil of strand on one of the reels 20 becomes exhausted. In the following these occurrences are generically designated as strand failure. Strand failure results in the insertion into the heel seat portion of the shoe of a less number of pegs than is required which, of course, is not desirable. To bring about, therefore, an automatic stopping of the machine on strand failure, the following mechanism, illustrated best in Figs. 3 and 4, is provided. There are pivotally mounted on the above-described shaft 56 in the bracket 44, twenty-two plate-like feelers I20, each of which is provided with a rearwardly extending screw eye I28 to which the upper end of a vertical spring I30 is secured. The lower end of the spring is attached to the bracket 44. The twenty-two feelers I20 are so arranged that a substantial portion of each feeler is'located behind each strand Sand is held by the spring I in. engagement therewith. Located-ilffront ofthe feelers I26 and extendingcrosswise over the twenty-two fiber strands is a contact-member I32 which has at opposite ends upwardly extend ing portions by means of which: it is pivotally mounted on the shaft 55. The contact member is so arranged thatit engages or is closely spaced from the twenty-two strands in front of the pertions thereof which are engaged by the feelers I26. Accordingly, the twenty-two strands S extend between the feelers I25 and the contact member I32 and hold the feelers in their normal operative position against the tension of the Springs I30, each of which tends to swing out its'respective feeler' I26 in a counter-clockwise direction as viewed in: Fig. 3. Thus, a feeler I26 may swing out as just described only upon failure of the strand S extending between it and the contact member I32. Such a condition is illustrated in Fig. 4- of the drawings. The Swinging out of one of the feelers I26 causes that feeler to contact the member I32 and also rotate that member in a counter-clockwise direction about the shaft 56. This movement of the contact member I32 is utilized in automatically stopping or throwing out of operation the strand feeding mechanism.

This automatic throw-out mechanism will now be described. It is illustrated in Figs. 3, 4, 5 and 6 of the drawings. The throw-out mechanism, of course, is normally inoperative and is adapted automatically to throw out the operation of thestrand feeding mechanism upon strand failure. The above-mentioned contact member I32 is.connected by a rearwardly extending link I34 to an arm I36 which constitutes part of the throw-out mechanism. The core of the throw-out mechanism is a shaft Hit-fixed in the machine frame. To this end the frame 22 of the machine has. secured to it a split bearing I40'6Figs. 5 andt) in which a portion of the shaft I38= is mounted and which is tightened, to bind the shaft, by a draw bolt I42 secured in position by a nut as iscustomary. Rotatably mounted onthe'freely extending outer end of the shaft I38 is 'a threearmed normally inoperative throw-out member I I- l. The member E45 has a normally upwardly extending arm I45 (Fig; 5) on which is provided a laterally extending sleeve I (Fig. 6) Rotatably mounted in the sleeve is a pin I50 toone end of which the above-mentioned arm ['35- is secured. The pin I50 is providedabout halfway between its ends and-at its lower portion with a recess I52 which extends transversely to the longitudinal axis of the pin and the top wall of which is somewhat curved, as best shown in. Fig. 5, substantially along a diameter of the pin. A corresponding recess or hole is provided in the sleeve I48. In the normal position of the parts, that is to say, when the throw-out mechanismis inoperative, and this position is illustrated in Fig. 5 in full lines, the recess I52 is so located that it does not impede the free movement through it of a pusher I54 which is secured on a segment-shaped member I56, the hub I-5'8-of.

which is rotatably mounted on the shaft I35- between the hub of the throw-out member IM- and the split bearingv I40 (see Fig; 6). The segment I56 is rocked during the operation of the machine by means of a link and lever connectionto the strand feeding mechanism. Thislink and lever mechanism comprises a link I50 pivotally secured by a pivot screw I52 to the segment I56. The other end of the link is pivotally connected by means of a screw I64 to an arm I66 which is 8 secured on the: :rock shaft 10 'of the mechanism for actuating the strand feeding mechanism. Asabove described, on strand failure-the feeler or feelers I26 previously engaging the strand or strands which have become broken or exhausted are swung out by their respective springs I30 with the result that thecontact member I32 also is swung out as illustrated in Fig. 4 of the draw ings. This results in a forward movement of-the link'I34 and in a counter-clockwise rotation, as viewed in Fig. 3 or 5, of the arm I36. This ro-" tation of the arm I36 causes counter-clockwiserotation of the pin I50 within'the sleeve I lBsothat the position of the above-described recess I52 in the pin I50 is changed with relation to the path of movement of the pusher I54. Of course, this 'rotation'of the pin I50 and the changein position of. the recess I52 can take place only when the pusher I56 is not located within the a pin I50 or, in other Words, when-the segment-'- shaped member ififi is substantially at the left hand end of its path of movement, as viewed in Fig. 5. When after the rotation of. the pin I50, as described, the segment-shaped member I55 is again moved toward'the right of Fig.5 the pusher I55 mounted thereon is caused to strike against the pin I50 after having moved through the above-mentioned corresponding re-= ces's or hole provided in the sleeve I48. As a result the pusher I55 moves the pin I50and with it the throw-out member I44 into theposition: indicated in dotted lines in Fig. 5. Thus, the throw-out member I44 is rotated in a clockwise direction from the full line position into the dotted line position of Fig. 5. This also results in a locking of the strand feeding mechanism as will be described. I To this end there is pivotally connected to' the downwardly extending arm- IISB of the throw-out member M l/a downwardly and forwardly extending rod I10 which passes through a trunnion block I12 rotatablysecured in the forked end of an arm I14 securedon a shaft I10 mounted for rotation-in a bearing provided in the machine frame, Secured ontheshaft I16" is also anupwardly extending latch arm I18 which is adaptedto cooperate with a latch I secured on the shaft 10. The rod'I1'0' carries on it a spring I82 which is confined be= tween the trunnion block I12 and a washer I84= (Figs. 3 and 4) held on the lower end portion of the rod I10 by lock nutsISB. It will be seen, therefore, that on clockwise rotation of the'throwout member I44 into thedotted line position of Fig. 5 by the-pusher I5 1- the-spring I82 is-active to rotate the arm I14 in a counter-clockwise direction asviewed in Fig. 5 as a result of which the latch arm I18 isbrought into engagement with the latch I80. Thus,- the shaft 101's lockedagainst rotation and continued motions of the rod 82 are absorbed by the spring 84. 'It Willbe understood that the-locking of the shaft 10' results in the strand feeding mechanism being rendered inoperative.

Moreover, since it is desirable on strandsfailure also to render the:j-ack operating mechanism inoperative, the throw-out member I45, has a third arm I88 (Fig. 5) provided with a lateral extension shown in Fig. 6 to-which' is pivotally secured' a rod I05. The rod I90 extendsdownwardly through a lug I92 provided on. the machine-frame and carries a spring I9 1 which is-confined between the lug I52 and a fixed collar on-the-rod- I90. At its-lower endtherod I90 is-connected by means o-frmechanism to be described with the jack control mechanismshownin Figs. -1 lthroughination of Fig. 14 that the jack and its controlling mechanism D are substantially the same as the fluid operated jack and jack control mechanism disclosed in United States Letters Patent No. 2,085,755, granted July 6, 1937, on an application of J. C. J orgensen. As disclosed and illustrated in that patent (Fig. 3), swingin move ment of a latch I86 out of latching engagement with a bar I16 results in the rendering of the jack control mechanism inoperative and it is with the equivalent of the latch I66 that the rod I90 of the present machine is indirectly connected, as will later be described in more detail.

It is sometimes desired to operate the illustrated machine for test purposes with the jack in operative position and with a shoe thereon but "without the insertion of fastenings into the shoe.

This, for example, is done when at the beginning of the operation upon a new run of shoes of sizes or styles diiierent from those previously operated upon, the selected size and position of the Wipers with relation to the heel seat portion of the shoe are to be tested. This means that during such test operation the strand feeding mechanism and the fastening inserting mechanism should be inoperative but that the jack control mechanism should be operative to permit the jack to locate the work in operative position with relation to the wipers. This end is served by the manually operated control mechanism which is illustrated in detail in Figs. '1 to 13, inclusive. This mechanism includes a bearing sleeve I96 (best shown in Fig. 9). The sleeve I96 is fixed in a bore I98 (Fig. 7) provided in the machine frame 22, the sleeve I96 extending outwardly from the frame 22 a certain distance. Rotatably mounted on the outwardly extending portion of the sleeve I96 are two

control members

200 and 202 which, as will be presently described, are normally connected together so that movement of one will result in movement of the other. The above-mentioned rod I90 connected to the throw-out member I44 is pivotally connected at its lower end to a lug 204 extending radially from the control member 200. The other control member-202 has a radial lug 206 which is positioned in diametrically opposite relation to the lug 204. To the lug 206 is pivotally connected a downwardly extending cable 208 which is connected at its lower end to the fluid operated jack control mechanism D, in particular, to the already described latch 260, corresponding to the latch I86 disclosed in the abovementioned patent to Jorgensen. Since the two

control members

200 and 202 are-normally coupled together they act as, and may be considered to be, a two-armed lever. Accordingly, on operation of the throw-out member I44 abovedescribed, in particular, on movement of that member into the dotted line position of Fig. 5, the strand feeding mechanism is locked and the rod I90 is moved downwardly, rotating the two

control members

200 and 202 in a counter-clockwise direction, as viewed in Fig. 10, into a position indicated in Fig; 11, thereb pulling up on the cable 206 to render the jack controlling mechanism inoperative in the following manner. Referring to Figs. 14 through 17, it will be seen that the cable 208 extends downwardly through a tubular guide 262 which is secured at its lower opening to .a fixed casting 264. The lower portion of the cable 208' extending downwards past the opening in the guide passes through a loose fitting bore 266 in a forwardly extending arm 268 which, with the latch portion 260, forms a bell I 10 crank lever pivotally mounted upon a horizontal pin 210. The lower extremity of the cable 208 is fastened to a lifting plug 212 suspended between the cable and an upwardly yielding spring 214. A plunger bar 216, which is equivalent to the before-mentioned bar I16 of the J orgensen patent, is positioned within a vertical slideway 218 in a fixed bracket 260. The bar 216 is normally held in the depressed position, as depicted in Fig. 15, by the downward force of a return spring 282, and the bar may be elevated to activate the jack by a thrust rod 284 which is treadle operated. The vertical travel of the bar 216 is limited by a fixed stop pin 286 which protrudes into a guide groove 286 out in the bar. The upper portion of the bar 216 is slidably journaled through a movable yoke 290 to which the latch 260 is anchored by the pivot pin 210; thus when the latch is engaged with a notch in the bar the yoke 290 will be elevated when the treadle is operated. A pressure valve (not shown) for operating the jack is directly connected to an arm 292 extending laterally from the yoke 290. The latch 260 is normally held in engagement with the bar 216 by the downward force of a spring 294 anchored at its lower extremity to the outer end of the stop pin 286. From the foregoing it will be seen that the jack operating valve may normally be opened by the elevation of the treadle operated plunger bar 216, however, upon strand failure the cable 208, as above described, will be pulled upward by the counterclockwise movement of the rotary control member 202, so that the lifting plug 212 will strike the lever arm 268 swinging the latch 260 counterclockwise out of engagement with the notch in the bar 216 so that the elevation of the bar by the treadle will be ineffective to lift the yoke 299 and open the jack operating valve. The machine cannot be restored to operative condition unless a new strand S is threaded between its feeler I26 and the contact member I32 and the contact member is manually pushed inwardly of the machine, thereby causin a resetting of the throw-out member I44 into its normally inoperative position illustrated in full lines in Fig. 5. This, of course, results in the unlocking of the strand feeding mechanism by the separation of the latch arm I18 from the latch I and in the elevation of the rod I by which the jack controlling mechanism again is rendered operative by the reengagement of the latch 260 with the bar 216.

However, as stated, a different state of affairs has to prevail when the machine is run for test purposes with the strand feeding mechanism and the fastening inserting mechanism inoperative, but with the jack controlling mechanism operative. This necessitates, first of all, a separation of the

control'members

200, 202 so that throwing out the strand feeding mechanism no longer affects the operation of the jack. The control member 202 carries a locking pin 2 I0, best shown in'Fig. 9, which extends parallel to the axial direction of the bearing sleeve I96 and which is adapted to enter into a hole 2 provided in the control member 200. In the normal operation of the machine the

members

200, 202 are thus locked together by the pin 2 III with the results described.

a rabbeted portion 220 which fits over the flange 2l8. The hand wheel 2E2 and the parts integral therewith are secured upon a rotatable and longitudinally movablebolt 222 which extends from the hand wheel 2 I 2 inwardly through the bearing sleeve 196 and thence further inwardly through the bore I98. Inwardly of the bearing sleeve I 95 the bolt 222 has a portion which carries a spring 224 .confined between the inner end of the bearing sleeve E95. and a shoulder .226 of the bolt.

The spring 224 thus tends to pull the bolt 222 inwardly. Outward movement of the hand wheel 2 i2. and'thus of the bolt 222 in the axial direction of the. bolt and against the tension of the spring 224 .causes the locking pin 219 to be withdrawn from the control member 299 and accordingly causes. the

members

200 and 222 to become disconnected from each other.

After unlocking or disconnecting the control members 292 and 202 b drawingthe bolt 222 slightly outward, the hand wheel 2 52V when turned in a counterclockwise direction as viewed in 'Fig.

1.0,. will rotate the control member '22!) in the same direction, without eiiecting any movement .of the control member 2132, thereby to pull .down

.the rod 190 and to throw out thestrand feeding mechanism by rotation of the throw-out member 144 into the dotted line position of Fig. 5 but to leave-operative the jack controlling mechanism.

Tocause-such rotation of the control member 200 the latter is provided with a pin 228 '(Fig. 9) outwardly extending through a recess 230 out into the periphery of the control member2il'2 and also extending. through a cut-out portion or recess 232, best shown in Fig. 12, provided in'the flange 21.8 of the hand wheel 212. Asseen in Fig. 12 the upper side of the pin 228 normally abuts one end of the recess 232 and this pin extends outwardsufiicient to still abutwithin the recess 232 while the hand wheel is withdrawn, so .that on rotation of the hand wheel M2 in a counterclockwise direction as. viewed in Fig. the pin 228 moves the control member 26!! along with the hand wheel 2 l2. Due to the provision or the recess 232, this movement of the pin 223 does not aifect the control member 202. This, of course, causes the spring Hi4 to'be loaded which then will tend to return the parts into their initial positionunless they are locked in their new position ofadjustment. Accordingly, after the rotation of the hand wheel 2 i 2 as described, the hand wheel again is moved axially, this time inwardly with the result that the pin 228 enters a hole 234 '(Figs. 8 9) provided in the bottom of the cup shaped portion 216 of the hand wheel 2|2. will be described, the hand wheel 2l2 may be locked in whatever position of adjustment it happens to be. Inwardmovement of the hand wheel 212 causes inward movement of the locking pin 210,- and entrance of the pin 210 in a hole 236 3 provided in the control member 290 adjacent to the hole 2H and spaced from the latter hole .a distance corresponding, to the extentof rotation of the control member 209 by the hand wheel 212.

It will be understood that the rotation ofythe I 12 tensioned spring .2 24. As is fully disclosedin the above-mentioned patent-to Willhauck, the machine disclosed therein has a plunger 144 which serves to operate the fastening inserting mechanism. The-machine illustrated herein has acorresponding plunger 238' (Fig. '7) which serves to operate the fastening inserting mechanism *in similar fashion by moving downwardly from the position indicated inFig. '7. This plunger 238, the same as the plunger .144 of the machine disclosed in the above-mentioned-patent to Willhauck, has a recess 240 which, when the plunger "238 is in its uppermost-position, is located opposite the bore 198 in which'the bolt222 is movable. Accordingly, inward movement of the bolt 222, as described, causes the bolt to enterthe recess '24!) and to lock the plunger 238. in its uppermost position, thereby rendering the fastening inserting mechanism inoperative.

' Forthe purpose of holding thehand wheel 2 l2 in either ofiits two positionsof adjustment the cup-shaped portion 2N3 has in its side wall two diametrically opposite, axially .extending notches 242 (Figs. 9 and 12) into which may enter-a tongue .244 extending axially outwardly from a plate 246 integral with-the outer end of thebearing. member I96 and apertured to permit passage therethrough of the bo1t'222. The tongue 244 enters the notch 242 when the hand wheel H2 is in its normal position in which the control -members-2llll, 202 are'locked together and arefree to rotate as a unit about the bearing sleeve I (see Fig. 8). Thus it'will be seen also that the hand wheel 212, before it can be rotated in a counter-clockwise direction as viewed in Fig. 10, has tobe pulled out first as described, not only to unlock the

control members

290, 292; but also tomove the cup-shaped-member 2| it away from the fixed tongue 244 until the latter is clear of the notches 242. After the rotation of the hand wheel 2l2 as described it is, as already stated, againmoved inwardly assisted by the spring 224, to lock the fastening inserting mechanism by causing the bolt 222 to enter the recess 240 of the plunger 238. However, the bolt 222 to this end has to move inwardly further than it normally is permitted to-move by the axial extent of the-notches 242. Accordingly, thereis provided in the member 2H5 adjacent to the notches 242 a second pair of diametrically opposite, axially extending notches 248 of considerably longer-extent than the notches 242. The notches 248 are so located that on completion of the rotation of the hand wheel H2 in acounterclockwise direction, as viewed in Fig. 10, to throw out the strand feeding mechanism the notches 248 are opposite the stationary tongue 244 which, on ensuing inward axial movement'of the hand wheel 212, enters the notches 248 :to hold the hand wheel in-its new position of adjustment, the notches '248 permitting the bolt'222 to move-inwardly far enough to enterthe recess 24!] of the plunger 238.

After the completion of the test run of the machine the operative condition of the machine is restored by a reverse manipulation of the hand wheel 21 2. In particular, the hand'wheel first is moved axially outwardly to withdraw the cupshaped member 216 from the tongue 244 and to withdraw the. bolt 222 from the recess 240 of the plunger 238', thereby. unlocking the fastening inserting mechanism. Then the hand wheel M2 is rotated in a clockwise-direction as viewed in Fig. 11 with the result that'the control member 2% is rotated in a clockwise direction back into its-initial. position under the. action. f r .the loaded spring I94, this back rotation of the control member 20!! being permitted by the pin 2 I B which, as a result of the first-described outward movement of the hand wheel 2 [2, also was withdrawn from the hole 236 of the control member 200. The hand wheel is rotated in clockwise direction as viewed in Fig. 11 until the notches 242 are opposite the tongue 244, whereupon the hand wheel 2 l 2 again is moved inwardly in-the axial direction, thereby causing the tongue 244 to enter the notches 242 and also causing the locking pin 2! to reenter the hole 2| l of the control member 200. This again locks the hand wheel H2 and also looks the

control members

200 and 202 together for free rotary movement as a unit about the bearing sleeve I96.
