Application May 16, 1935, SerlalNo. 21,859 36 Claims. (01. 140-71) This invention relates to an improved wire folding, cutting and handling machine. The primary object of the invention is to provide an improved machine-of the character indicated 5- adapted to fold the lead wires of electric detthe leg'wires of detonators into a group of figure-B loops with each loop lying in a plane in adthat the wire may be drawn out into a single straight strand when the time of use arrives,

without any intertangling or kinking of the wire. I

A further feature of novelty'inherent in the new machine is the provis on of means for applying retaining clips to the bundles of wire after theyhave beenv wound but before they are removed'irom the pins upon which they werewound, said clips serving to retain the various loops of the bundle in proper relation ,to each other during the succeeding operations of attaching the wires to the detonators and applying theshuntsto said wires. After the wires have been placed in the packaging tubes as shown in the McFarland patent above referred to, the tubes themselves hold the'wires in their established relation. The clips applied bythe machine of this invention serve to hold thevarious loops of the wound bundle in their proper relation, as stated, between the time at which the bundle is wound and the time of application of the tube to the bundle; V

v A further object of the invention is to provide 7 a machine of such construction that a plurality of. bundles .may be wound simultaneously and through the instrumentality of a single shuttle actuating'mechanism'. -To this end the machine employs a plurality of shuttles mounted upon a traverse mechanism, common to all of said shuttles, said, traverse mechanism being of a nature to wind-thefivire in a figure-8: path after themanner disclosed in my prior patents aforesaid.

5 ferences, the machine of the present application Vance of the planeof the loop preceding it, so

"In addition miles. improved mnctionm dif- 9 comprises various refinements in construction by virtue of which the desired results are accomplished in a facile and efllcient way. For example, the new machine embodies a greatly simplified ejecting mechanism by which the 5 wound bundlesare ejected from the pins upon which they were wound; improved insulation removing and wire cutting means, and scraping means by which ttle insulation po'unders are kept'f ree of particl s of insulating material.

Further objects and advantages of the invention will be set forth in the detailed description which follows. y

Fig. 20 is'a diagrammatic view illustrating the manner of winding the wires upon the'pins as,

hereinafter set forth.

Like numbers designate correspondingparts in all of the figures of the drawings. Power for actuating the machine is derived from any suitable source such for example'as the teeth, while the gear wheel l5 has only half as I many teeth as the gear wheel l4, and thus makes two revolutions to each revolution of the gear wheel The gear l5 imparts horizontal reciprocation to a cross head I6 that is slidably mounted in ways I! of the main frame.

Spaced vertical standards H! are rigidly affixed to the cross head IE to partake of the horizontal reciprocation of said cross head. These standards are tied together at the top, as indicated at l9, and it is between these standards that the shuttle actuating slide I3 is mounted for vertical reciprocatiorr For purposes of explanation, I have illustrated two shuttles 20 and 20a, these shuttles being caused to describe identical paths with respect to associated winding pins, as presently set forth. I wish to make it clear, however,

that more than two shuttles may be actuated simultaneously from a single shuttle carrying and actuating mechanism, if desired.

Spool like members 2| uponthe shuttles receive the edges of a pair of spaced bars 22 between them. These bars are tied together at their upper and lower ends as indicated at 23. Rods 24, which are tied together by a cross bar 25 and are slidably supported in bracket 26, and standards l8 carry the bars 22, through block like extensions 21 of said bars 22. The upper ends of actuating levers 28 are rounded for engaging in end recesses of said blocks. The lower ends of these levers are pivoted at 29 to a bracket extension of the spaced standards l8, and said levers are actuated by cams hereinafter described.

Since the cross head |6 makes two horizontal strokes to each vertical stroke of the shuttles, it follows that. each shuttle"; will describe a figure-'8 path to bring about the laying of the wire to he wound in figure-aform upon the pairs of winding pins 30, 30a, 3|, 3|a. At the beginning of the winding of the wire upon any given. set of pins, these shuttles are projected to their limit of movement inwardly, or toward said pins, so that the winding of thewire is from the inner portions of the pins outwardly toward their ends, and as the winding proceeds, a lateral traverse is imparted to the shuttles through the medium of the arms 28, so that the wire is laid upon the pins in progressive, non-intersecting, and non-tangled loop formation, as illustrated in Fig. 17.

The winding pins 30, 30a, 3|, 3|a, are fixed in disks 32 said disks being splined upon the turret being adjusted toward and from each other upon said shaft through the medium of set screws of conventional form, indicated in dotted lines at 34. The length of the bundles may be increased or diminished by adjusting the pairs of disks 3! away from or toward each other as the case may be, and, to adjust the stroke of the connecting rod I2, when adjusting thelength of the bundle, the gearwheel II is provided with a plurality of openings |2a for the reception of the crank pin I 2b by which the connecting rod is actuated, said openings 2a being varying distances from the center of the gear The number of wraps per bundle may-be varied by changing the ratio of the chain drive to the high speed shaft of the reducing mechanism hereinafter described.

For ejecting the wound bundles from the pins, strippers 35, of inverted U-shape, have. their legs 35a, 35b slidably mounted upon said pins and have their intermediate portions guided in recesses 36 ofsaid disks 32. Springs 31 tend to retract the strippers and to cause wear plates 33, carried by the leg members 35b of said strippers, to bear against the cam, faces 39 of fixed disks 4!], 4|.

The fixed disks are in turn carried by the turret cap 42. These fixed disks comprise cam ways 43 and the shape of the several cam surfaces is such that, guiding the ejectors during the rotation of the disks32 with respect to the fixed disks 40, the ejectors are fully retracted at the winding position, as indicated at X in Fig. 6. These ejectors are fully projected against the tension of their springs 31 by the time that they reach the discharge position of the bundles, as indicated at a Y in Fig. 6, and are gradually returned to fully retracted position during the time of their travel from position Y to position X.

The lowermost disks 32 carry guide pins 44, there being one of these guide pins between each of the pairs of winding pins. After one bundle has been wound, the turret constituted by shaft 33, disks 34, and associated parts, isindexed or stepped forward'to bring the next set of winding pins into juxtaposition to the traveling shuttles. In its initial movement, the wire is first looped over a guide pin 44 of the lowermost disk 32 of a pair of said disks, and is next carried over the upper winding pin 30. This causes the wire.

. two pounders. Each pounder comprises a shank 48, angular in cross section to cause the pounder head, and the cutter carried by said pounder head, to maintain the proper oblique position to insure that the cutter will. engage the wire substantially at right angles to its length; it being remembered that the wire extends obliquely across the face of the anvil because of the fact that it extends from a lower guide pin 44 to an upper winding pin 30 or 3| as the case may be. The shanks 48 are slidable in block 41, and the pounder heads comprise steel pounding blocks 46a (Fig. 16) which perform the actual work of crushing the insulation.

The shanks 48 carry transverse bars 49 at their outer ends, and pairs of springs 50 are connected to these bars through the medium of adjusting screws 5|, the opposite ends of said springs being connected to studs 52 that are carried by plates 53.

It will be seen that the springs W'tend to thrust 9,091,579 the pounder heads 38' forcibly toward the anvil 45.. Cutting plates 54, carried by the pounder heads, serve the function ofractuallysevering the wires, while thepounder heads themselves serve merely to crush the insulation fromthe wires and leave the terminal ends of said wires free of insulation, it being understood that one end of the wires of each bundle is to be attached to an elec trio detonator, while 'the other end receives a 1 safety shunt and serves as the attaching means by which the detonator is to be connected tothe firing cable of a blasting machine, when the time of use arrives. v

The shanks 48 of thepounders and cutters carry pins 55 which project outwardly through slots 58 of a side plate 51. These pins are thrust outwardly to place the springs 58 under tension, by swinging arms 58 which are connected to escillatory shafts 59 and 58; Gear wheels 8| and 0 62 upon these shafts mesh with each other and the gear wheel 5| is engaged by a rack bar 83.

' When the rack bar is drawn downwardly (Fig.

13) the pins are thrust outwardly until detent latches 64 and 55 snap into notches 68 of the 5 shank 48, said latches then holding the pounder heads in retracted position during the return or upward movement of the rack bar 89 and until a trip bracket 61 carried by one of the arms 58 engagesa pin 68 on one of the latches 84 to retract said latch. The movement of this latch is imparted to the other latch 55 through a piv-1 oted rock lever I8, and thus both pounder heads are released at the same time, and the springs 58 act to thrust said pounder headsand cutters.

forcibly toward the anvil for the purpose of crushing the insulation and cutting the wire, as aforesaid. This moveinent is limited by contact of. bosses 58' with cap plate 41'.

The rack bar is connected by a suitable link 8 mechanism II to a lever 12. (See Fig. 2.) This lever is pivoted at 13 to the frame of the machine and its-free end is slotted and engaged by a wrist pin ll of a crank disk I5, that is actuated from the slow speedshaft of a conventional re- 45 ducing mechanism I8. I

The details of this reducing mechanism have ot been illustrated, because these are common- ,mechanic'al units which may be purchased on thtg L open market having driving and driven shaf of varying speed ratioswith respect to each other; The ratio employed in the present machine is preferably about 12:1, but this ratio may be varied if desired. The high speed shaft of the reducing mechanism is driven through a silent chain or sprocket mechanism 11 from the I shaft of gear wheel I4, said high speed shaft being 7 indicated at I8. The low speed shaft of the re-,

ducingmechanism is indicated at I9, and this shaft is suitably coupled to a corresponding low speed shaft 88 (Fig. 1) which carries cams 8I by which the arms 28 are actuated to impart the desiredtraverse to the shuttles 2I'. These cams; engage a suitableroller 82 carried by said arms.

(See Fig. 17.) r

After the bundles have been wound and after they pass beyondthe anvil, the winding pins ,by

which they are carriedcome to rest in front of the clip applying mechanism, indicated -generally at- C, Figs. 2, 3, and 4, and. illustrated in detail in Figs. 7-40. This clip applying mechanism is carried bya bracket 83 which projects from the pounder body. (See Figs. 1 and 1 2.)

By referring to Fig. 9, it will be seen that this bracket-83 supports a plate, said plate carrying forwardly projecting bearingextensions 85 are connected to move in unison by a cross head' 81 and this cross head is projected forwardly by the actuation of a bell crank lever 88 and retracted by the action of a spring 89 .The forward ends of the pusher bars are notched as indicated at 86a to adapt them to securely engage the rear; ends of the clips 98 and to thrust said clips forwardly to engage the bundles at about their central portions. Fingers 9i are pivoted at 92 and carry pins 93 at their forward endportions. The pihs 93 project through slots 94 and are engaged by springs 95. (See -Fig.,10.) The fingers hold the clips in proper position until the pusher bars eject the lowermost clip of .a pile, the piles of clips being received in magazines 95'. Acarrier bar 98 (see Fig. 11) provides means for holding the clips in assembled relation during the time that they are being carried to and deposited in the magazines 95'. I

The bell crank lever 88 of Fig. 7 is actuated by link 91, and this link is, in turn, actuated by a rocking lever 98, to one end ofwhich link 91 is pivoted; Lever 98 is in turn pivoted at 98 and carries a roller I at its free end, said roller being actuated by a cam 'IIII, driven from the slow engaged by the nose I84 of a pawl I that is pivoted to a horizontally sliding bar I88. A locking plunger I81 has'a nose I88 adapted to engage in the locking notches I89 of the locking disk. Whenthe bar I88 is moved toward the left in Fig. 19 a pin I III, which engages a shoulder on the locking plunger, moves said: plunger out of engagement with the locking disk, and then the nose I84 of pawl I85 engages a tooth of the ratchet disk to impart one step of rotation to the turret.

The pin I I8 carries a lateral extension III, and said pin is held in an elevated position by spring II2. When the pin III rides beneath the cam surface II3 of a bracket M4, the pin is depressed and the locking plunger is released and shoots forward preparatory to again engaging the locking disk when the next notch of said disk comes 'into alignment with the nose I88 of said plunger.

The construction of this part of the machine diilfers from that of my prior patents only in the means for actuating the locking plunger, which means, in the present instance, comprises a lever II5. This lever is pivoted at its lower end as indicated at I I6 and is pivotedly connected to the outer end of the locking plunger at I I1. A spring II8 tends to project the locking plunger I81 toward the locking disk. The bar I86, as in my patents aforesaid, is actuated by a swinging lever I I9, the upper end of which is hung upon a pivot I28. This lever passes through the bar as indicated at I2I in. Fig. 3 and its lower end is disposed tobe engaged by acam I22 of a sleeve I23ehat is splined upon and rotates with the shaft I24 of the intermediate gear wheel ll.

The sleeve123 is urged toward the right by a spring I25 which bears between said sleeve and a collar I26. However, movement of the sleeve toward the right is resisted by the engagement of bearing blocks I21, only one of which is shown,

between collars I28 of said sleeve. These bearing blocks are carried by a lever I29 of yoke-like formation. Said lever is pivoted at its upper end, as indicated at I30, and its lower end is provided with a wear plate I3I, adapted to be engaged by a wear plate I32 of a trip lever I33.

When the inner end of this trip lever is depressed to free yoke I29, and consequently to free the sleeve I23, said sleeve moves bodily toward the right; cam I22 is brought into align-. ment with lever I29, and as this cam rotates, the lever is swung upon its pivot to move the bar I06 endwise and consequently to index the turret one step.

It will be observed that there are 12 teeth to the-ratchet disk, while there are only 6 sets of pins to each shuttle. However, it will' also be observed that the additional guide pins 44, car ried by each of the lowermost of the pairs of rotative disks, make the total number of pins, considered circumferentially with respect to the sev-' eral disks, equal in number to. the notches of the ratchet disk. Thus, two actuations of the ratchet disk take, in the advancement of the turret, a dis- --tance equal to the distance between the sets of winding pins, and during the first of these movements, the wire is looped under the'guide pin 44.

Referring now to Fig. 18, it will be seen that the controlling means for the several mechanisms hereinbefore described are concentrated in and about the reducing mechanism. In this figure, I have illustrated the connection between the slow speed shaft I9 of the reducing mechanism and the shaft80 which actuates the cams BI of the shuttle traverse mechanism. Since the r'educing'mechanism I6 is fixed to the frame of the machine, while the cams 8I reciprocate bodily, horizontally with the cross head I6, it follows that the connection between the slow speed shaft I9 and the shaft 80 must be a sliding one.

To effect that resultfI have provided a sleeve I34 that is keyed at I35 upon the shaft I9, said sleeve having a reduced internal bore I36 having splined engagement with a correspondingly shaped end I31 of shaft 80.. I

, A flange I38 upon the sleeve, in conjunctio with. a disk I39, constitutes a recess I40 within which the arms of a yoke I 4| are received; This yoke is provided upon one of its sides with acam I42 adapted to be engaged by a roller I43 of a crank arm I44, said crank arm being mounted upon and turning with the sleeve I34. function of the roller I43 is to engage beneath the cam I42 to elevate the yoke and a rod I 45,

said rod constituting the actuating means for' the trip lever I33. This lever is pivoted intermediate its ends at I33a, and when the rod I45 is drawn upwardly by the cam roller acting upon cam I42 (Fig. 2), lever I29 will be released and, through the connections described, the turret will be indexed forward one step.

Further, the sleeve I34 carries a cam I46 for operating the scraper mechanism by which the pounder heads are kept free of accumulations from the crushed insulation. The scraping means comprises a reciprocatory bar I41 that is slidably mounted in a guide I48, supported from the pounder mechanism. A spring I49 tends to keep this bar and the parts carried thereby in engagement with the cam I46. The cam and spring act to-reciprocate this bar and move spring steel ly falling within either The- ports.

the rock lever 98, for the purpose of actuating the bell crank lever 88 of .the clip mechanism, as hereinbefore set forth.

It is common practice in wire winding machines of various kinds to apply tensioning devices to the wires to take up undesirable slack, and to keep the wire taut' during the winding operation. I contemplate the use of any such ten sion device, the particular form of which may vary widely without affecting the proper and cilicient operation of this machine. The machine of the present invention is intended to handle wire, which, while flexible, still has such inherent stability and resistance to change of form that when it has been wound to figure-8 form it will retain that shape to constitute permanently formed, progressively disposed loops; until the wire is positively drawn out by the operator. respect the invention differs from mere thread winding devices which wind threads of such a low degree of stability that they would tend to fall into many diiferent shapes as soon as released from the pins upon which they are wound.

It is of course apparent that many ways will In this readily suggest themselves to the skilled engineer for accomplishing the results at which this invention aims, while employing means different from thoseshown and described. I therefore wish it to be understood that the invention is not limited to the construction herein disclosed, but that it includes within its purview any structure fairthe terms or the spirit of the appended claims.
