TACKING MECHANISM.

Patented Mar. 2, 1915.

Application filed April 17. 1911. Serial No. 621,514.

To all whom. it. may concern Be it known that 1. hoNALI F. Mcl senr. a citizen of the United States. residing at Beverly. in the county of Essex and State of illassachusetts. have invented certain lnr provelnents in Tacking illechanisms. of which the following description. in connec tion with the accoi'npanying drawings. is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the nninufacture of boots and shoes and particularly to fastening inserting machines.

The invention is illustrated as embodied in gang tacking mechanism of an asse1nbling and automatic heel scat lasting machine more fully disclo d in my application. Serial No. 512.9%. tiled August 114, 1909 of which the present application is a continuzv tion as to subject-matter common to the two cases.

The object of this invention is to improve nailing or tacking mechanisms herein designated tacking mechanisms and particularly to provide a gang tacking apple ratus adapted to meet the requirements of heel seat work in automatic or semi-auto matic machinery.

An in'iportant feature of the invention consists in the combination with twoor more drivers of a tack supplying mechanism and actuating means arranged to cause the sup plying mechanism to separate a succesion of tacks and deliver them between two op erations of the drivers.

A gang tacking machine for heel scat work is required to drive a large number of tacks notwithstanding the fact that a given number of tucks inserted by such a machine as the present one has as great holding power as a larger number of tacks inserted one at a time. To provide a machine with a number of raceways and separating devices equal to the number of tacks to be driven would render the machine cumbeu some and expensive. I have discovered that the required results can be obtained by an arrangement and construction by which the tack supplying devices are caused to operate a plurality of times during a cycle of the machine in which the drivers operate once. In devising a machine embodying this featitre of the invention there was encountered the condition that for the best results the delivery ol' tacks to all the drivers should be simultaneous.

A further feature of the invention is to he ria o irnizml in provision for sepaint ug sue lti-:-d\l t-ll'lts ol' tacks and holding: one or more so. as in transit until the full charge is ready and thou deliwring at substantially the sane time the tacks rep-.lrato'l at dilicrcnl tim s. its the machine is shown one series ol ta ks is separated and l'alls into a remix inn plate and then substantiallysimultaumusly with the separatigni ot a. second series o! rocks the receiving plate is moved to bring its tack tilled openings into aline' men! with one series of conductors and to place a second series ot opening.-- in alinement with the separator and with a second series ol conductors so that the second series oi tat-ks discharged nearly simultaneously with the 'lirst series. it desiraliile feature of the construction }i l'()\l(l65 for two complete recipromitions forth and hack of the separator derived from a single rotation oi its actuator.

The machine is provided with a shoe sup port and with power mechanism which positions or ntlu-rwise prepares the shoe to be operated upon and then automatic: ll comes to rest to allow inspection and adinsttncnt oi the shoe. It sometimes occurs that we :uuination discloses that tlu: shoe will not be properly fastened by the continued operation of the machine but requires to he taken out and its parts rearranged or th preparatorv operations. such as lasting the upper materials. need to be repeated.

A feature of this invention contemplates the provision of novel mechanism by which the driving of the tacks can be suspended until a later cycle of the machine's opera-- tion. Another and ver; mportant teatureot the invention consists in means for suspendlog; the separation and delivery of :1 second charge of tau-ks while a charge already dc livcrcd is awaiting delivery as stove cxplained. These "features are embodied in manually operated means for' preventing the descent oi spring actuated drivers and in means for locking an oscillating actuator against a sullicient movement. in the dircction in which it is yieldingly actuated. tor ellcet separation of any tacks. This locking means is controlled bv a hand lever which,

after ha ring set the stops, can be reversely moved. to cause the driving and feeding of the tacks at any time before the end of the nnichines cycle.

A further feature of the invention con sists in means for eilecting the Withdrawal of the stops autonnitically during the preparatory o erations of the next cycle so that itiioat special attention from the operator the shoe will be fastened during the repeated operation of the machine on it.

Another feature of this invention consists in the combination with a plurality of tackrrs. or gang tackcr members, which are arranged for movement inwardly over an end portion of a shoe bottom toward tacking posiion in converging lines until arrested in positions determined by the size and position of the shoe. of a back stop adjustable for large and small shoes to determine the positions in which the tacksshallbeinserted, or the spacings between the rear end tacks and the side tacks. By setting the stop, and then-lore the shoe. Farther back for a large shoe. the side tacl-ts can always be made to man at the cm rcct relation to the breast line of the heel scat.

"ihc everal features of the invention, includ ng ertain details of construction and combinations of parts will appear more fully from the following description of the invention in connection with the accompanying drawings and will then be pointed out in the claims.

Figure l is a side elevation of an illust arii'c cailmdimcnt of the invention; Fig. is a vertical longitudinal section; Fig. 3

a plan iew oi the devices for holding the or or the he l seat tacking operation; Fig. I is a perspective view of the tack drivin; apparatus: Fig. 5 is a perspective view on" the tin-k supplying mechanism; Figs. 6 and 3 are successive sectional views of the ta k delivering mechanism; Fig. 8 is a pen Sportive view illustrating the operating means for the tack delivering mechanism.

The machine comprises a baseQupon the u of which is mounted the head carrying tin tacliuin' mechanism toge'rther wit. mechanism t'cr preparing the shoe forlhe tacking opcrulioh and to the side of whi-h near the front is pivoted at "l the part of the shoe sup port or jack carrying the shoe assemblivw and upper polling apparatus. The ]tl(' int i :an Hm ing outwari'lly to clear the last thereon from the machine for giving access to all sitlcs of the SllOeiH applying the last to thehcel pin ind assembling and adjusting the upper materials and the innersole in proper relatiin. The arm 8 trends upwardly from the pindle l0 and in its forwa d i'm-vtion. which is bent outwardly and then back i in around the toe portion of the shoe. has a horimntal guideway located directly below the last in which a block 15 is adjustable lengthwise of the shoe. This block comprises an overh, ging arm 16 which has a rest H for engaging the bottom of the last or the inner-sole thereon, the toe end of the last being held up by a spring 18 acting upon the heel pin, and a rest 19 for engaging the end face of the last when the block has been adjusted to the right position in the arm 8 for the particular shoe in hand. The block 15 supports pivotally the upper pulling device 22 which has an operating handle rod 28. The rests .17 and 19 constitute convenient means for positioning the innersole lengthwise on the last bottom if the innersole is unattached to the last as it is in the manufacture of many shoes. The jack includes a spring 3 which as shown in Fig. 1 is strong enough to uphold the spin dle 10 with the shoe thereon and when the upper has been satisfactorily pulled toeward and fitted to the last the jack post is swung inwardly, within the heel band and against a suitable back stop 69 the shoe being depressed to permit it to go under the heel bottom rest 100 which will be described. The lower end of the spindle 10 is formed as a rack 11 which engages a pinion 12 on the shaft 4 upon which the jack post is pivoted. This shaft 4 also has a rigidly attached ratchet wheel 41 which is engaged by a pawl on the lower end of a rod iz to turn the shaft 4 and its pinion 1:? in the direction for uplifting the spindle l0 and the shoe from the power shaft during the operation of the machine for purposes which will be described. A similarly constructed but horizontally arranged rack bar l-l, pinion 15, ratchet wheel 16, and pawl 1?, connection is provided between the jack post and a rod 43 for inswinging the jack and the shoe from the power shaft, and these rods are connected to bellrranks =14 mounted on a fixed pivot rod 7 as shown in Figs. 1 and 2. The outer ends of the cranks :lt rest upon springs 45 in the outer arm of a bell-crank 46 the upper arm of which is a segment 9 which, through suitable connections later described, receives motion from the power shaft. This upward movement of the rods is transmitted to them by the independently yielding springs 45 and turns the ratrhets in the direction to uplift the spindle and shoe and to pull them hackwardlv into the machine.

The inechanisn'i into which the shoe is thrust hacluvardly for positioning and holding the work for the tacking operation includes a. plurality of separately movable parallel cords, bands, or the like 50 arranged to extend about the heel portion of the shoe from the shank on one side to the shanklon the other side. A lining 58 of leather, rubber, felt or other suitable. material is arranged within the bands 50 and distributes the pressure of the bands Without interfering with their relative conforming movement to adapt them to the contour of each last when they are put under tension to as sist in holding the upper materials in position to be fastened. This is ell ected through a toothed angle 62, see Fig. 2, fulcrumed nt 6? and having :1 roll in engage ment with the rear cam Fare 64 of the C21!!! block $5. This cnni hlock curried hy the cam shaft iii which is driven through a clutch and connections to the lower pulley shaft 68 which driving ports are or may he Substantially like those shown and claimed in United States Lette s Patent No. Till .686, of June 6, 1905. This clutch mechanism need not be here further descrihed than to state that it is actuated hy a trendle to cause the machine to he stnirtcd and that the rain disk X31 has suitably tm'metl nod located 'ises t enlist the machine illlti lliilti call)" to come to rest at predetermined times which will he later notei. The slide 61. which through snitnhle connections. not shown. closes the heel hand 50, is actuated from the cam face 65 by the angle lever 62 and pinion 60 and is toothed on its lower face as shown in Fig. 2 to engage the upper arm 9 of the angle lever 46 before described by which the shoe is lifted and pulled hack. into the machine and is locked there to receive the heel seat lasting operation. The. back stop (59 is ndjnstnhl moinited in position to limit the backward movement of the shoe into the elastic heel hand which is effected by the connection to the incl: post through the rod 43. This insures u predetermined positioning oi the shoe lengthwise with relation to the operating parts of the machine. The back stop is forked to center the shoe laterally independently of the hand and thus assist in positioning the shoe lot mull with relation to the tucking: nicchn. nism. The hack stop is shown in Fig. '3 as formed on it rack bar ndjiustnhlo h n. shaft (190 having :1 handle at the side of the machine with a. pawl in it to change a loching ratchet 691. Fig. l. which has marked on it grndnations indicating the proper ndjustnient t'or diil'erent sizes. The ratchet can he ndinsted to position the grmluw tions for different groups of sizes. lllli hi5 mens. womens or childrens sizes.

The tnckers, of which there are live each equipped to drive two tacks. are shown host in Fig. -l where the rear end one is indiciitcd at 85 and the front ones at 95. Tl'ieso tnclici's are arranged for movement yield-- ingly in converging lines over the heel sent. from on open position, Fig. 3, in which the heel is fully uncovered to a. tack inserting position that is determined by the size and position of the shoe. The tackers, or more specifically the swiveled tack blocks 120 thereof. have each a depending feeler or gage 122 to engage the side face of the shoe, or the counter -elallnping band thereon, and

limit their inward movement with relation to the previously clamped shoe. The mmfi ment of the taclcers is ohtnincd from the coin lilocl; 65 hefore mentioned its lni ting the coin face (it for actuating the jnt'li to present the shoe in position to he tnrlioil. This coin llluuihas kitlll puth Th. Fig. '3. in which stands :t roll 76 on a slide Th. Figs. '1! and 3.

The spacing lHlWLQll the pairs of tucks will. howeirifviii'v liti'rording; to the. size of the shot and its iongri tndinnl position in the llltll'llllll? hecnnse the intermediate tacli'ers niove obliquely toward the side tnckers and operate more or less close thereto according to the width of the shoe while the space between the intermediets and. rear end pairs of tucks is varied according to how far hack into the machine the shoe extends. This is controlled by the adjustable beck gage 69. The movement of ll; will he the wipers is different and is relative to the side tackers because the side wipers are advanced lengthwise of the shoe by their connections 71 with the rear end wiper. It may 5 be here explained that the actuation of the wipers toward the shoe is effected by the arms 8'1 f through slots 842 in which rise studs 84-0 from a subslide 850 in the end of which a wiper is carried. This is indicated 10 in plan in Fig. 3 and in perspective in Fig. 4. This connection 840, 842 insures the advance of the wipers with the tackers and slightly ahead of them until the engagement of the gages 122 arrests the advance of the tackers and compels the arms 84 to swing laterally against resistance of springs 88. The shape of the cam slots 842 is such as to effect retraction of the wipers from under the tackers far enough to allow the tacks to be driven into stock previously covered by the wipers. Interengaging shoulders 89 on the wedge slide 83 and arm 84 insure the return of the arm to normal position and the Wipers to normal relation to the tackers at the end of each cycle.

The shoe bottom rest controls the vertical position of the shoe which is lifted against it by the connection, earlier described, with the power mechanism. The shoe bottom as rest 100 is formed as shown in Fi 4 to contact with the shoe bottom at a p'urality of pointsincluding points at opposite sides of the innersole near the heel breast line to position the shoe as to transverse inclination of the heel bottom and to clamp the insole down firmly upon the lust bottom near its opposite edges. This bottom rest is movable endwise in a guideway formed in the lower face of a block 102 and is pressed forwardly 40 therein by a spring 103 against an adjusting screw 1051-. This allows the rest to accompany the shoe backwardly into the machine in the indrawin movement effected by the rod 43. The bl ock 102 which carries the bottom rest is guided for vertical movement in the machine head and has rack teeth engaged by a pinion 105 coupled by a rack rod 10'? to a lever 108 which is fulcrurned at its upper end and is held by a spring 109 acting on the rack rod, against a cam face 110 formed on the front end of the cam block 65. This cam face is formed with relation to the cam track 75 for the bottom rest to be raised after the tackers have advanced 56 over upon the shoe bottoin whereby the upper is caused to be firmly compressed upon the last bottom to form a firm smoothly prepared surface to be tacked. The lifting of the shoe is effected by the formation of the 60 face 64 of the cam, movement being transmitted through the strong spring 45 located in the jack lifting mechanism which has been at under tension when the jack was initial raised. The cam face 110 is also 66 formed to depress the bottom rest again blocks 120 of which there are after the tacks are driven, as will be de scribed, and before the wipers are finall retrncted. This is to depress the shoe mm the wipers and to relieve the )IESSUIG of the wipers and prevent them f rom. dragging over the lasted and tacked uppers in their final retraction. The cam face. i l will referably be formed to relieve the uphol ding pressure of the shoe at this time.

The tackers 85 and 95 support the tack five mounted in said tackers as shown in Figs. 3 and 4 to have a small amount of angular movement in a horizontal plane. These blocks have projections extending downwardly through slots in the wipers and carrying feelers or gages 122 arranged to engage the side of the shoe, or the counter clamping bands and thereby limit the inward movement of the tackers and also determine the position with relation to the edge of the shoe at. which the tacks shall be inserted. The gages also effect the necessary turning of the tack blocks in their slides to position at substantially the same distance from the edge each of the two tacks which the blocks are arranged to carry. The tack pockets in the blocks .120 are in clined so as to drive the tacks toward the center of the heel and the drivers 124 are similarly inclined. This arran enient provides that the ingoing tacks Whlfil are simultaneously driven all the way around the heel seat shall by reason of their inclination draw the u )pe inwardly from the edge of the last. These tacks are driven in front of the wipers into a portion of the upper materials which therefore is not at the mo ment of driving held down in lasted position and. the indrawing effected by the inclined tacks is therefore particularly adiantageous because it takes up or reduces the slack that otherwise would be liable to exist between the line of tacks arev of the wipers. A single drive ries two drivers 124 and the t ment of the tack block 1.20 tak the axis of that rod which is a slide block 123 and a ball driver plate 126 guided to hit. lines in the machine head. is the broadened front end of a e fulcrumed at 1528 upon a link 129 and a depending hinged link 130 the foot 0 which rests upon a earn 132 on. the front end of the cam shaft 66. This cam Se! see to lift the driver lever and the drive s against the tensionof s rings 13 suspto E d by rods 133,1 ig. 1, .rom the lever to he wnprcssed against a shelf 135 on the tram preparatory to actuating the driver is e downwardly to insert the tacks when the cam permits said springs to close. Adjustable stops 136 on the frame limit tht down streke of the drivers and determine the extent to which the tacks shall be driven.

her the machine is 1-,moeee A forked slide block 1st see Fig. 2, resting on the machine frame is adapted to be advanced by a T lever pivoted at M3 and having a handle :irm H5, into a position under shoulders 1.46 on the lever-raising link 130 and prevent the descent of the lever for driving the tacks if, after the operator has had opportunity to examine the shoe in the machine. fastening of the upper not desired Eor any reason. The slide block may be manually retracted to permit the driving of the tacks in a later portion of the machines cycle, or if the shoe is not properly prepared for fastening and must be submitted to a second cycle of the machines operation the block may he left until. a suitable time in the next cycle when it will be automatically retracted by the engage-- ment of a wedge 148 which shown as carried by the rotating tack hopper 150 with the upper arm l-l-T of the lever. The tacks are fed by mechanism later to be described from the hopper 150 which is oscillated by a rack bar 152 through spring 17:4 from av cam track 155 in the side of the cam X on the cam shaft 66. These parts do not in theinselics form a part of this iuvention' and mav be of previously known construction. The hopper has a stud 156 between which and the wedge 148 the arm 14-? is set hen the s ide block H0 is advanced to obstruct the descent of the drivers. This stud prevents the osr-ill: ition of the ho 'lpcr through a (treat enough angle to client the s rmration and feeding of a srronrl set of tacks until the which is Waiting to be d ven has been inserted and if the crclr of the nmr'hine completed Without driving the wait ng set then the feeding met-hanism is rendered inetl'ecti e for that m'rle but the WPIlQQ 149 f'orces the tack stonping' devic s to no mal pos t on in (inn to perm t. drli erv oi the Withheld tarlrs for the next c cle.

The tacks which gnvitatc down the raceu'a" groo es Fig. 5. from the honoer are separated bv a slide 160 with which moves a notnhvd gate 162 and are delivered through the oblioue slots and evesin said plate as describ d in row nr or United Ftates Letters Patent No. 1.002.421. granted September 5, 1911. There are five racewvavs and the separating mechanism is arranged to be reciprocate l twice in each cvcle of the machine to deliver ten tacks which is the non designed to drive at one time. To this end a receiving plate 164: is provided which is guided for endwise move ment between the conductor or tack tube anchor plate 165 and a cap plate 166. The receiving plate has ten pockets arranged in two series alternating and so positioned that when the first series is in mm ing position the points of the tacks will rest upon the anchor plate and will not be discharged into the tack: tubes until the receiving plate has been moved to put the second series of pockets in receiving position in time to take the tucks from the second actuation of the lwparating devices. At this time the first sot ol" tacks will be discharged into the tubes and the second set will fall directly through. the receiving plate into the tubes as shown in l ig. 6, so that the two sets of tacks fall into the tubes which lead them to their holders in the tankers, Fig. 2 at nearly the same time. This concentrates the tack do lirering period and leaves the remainder of the time occupied by the cycle of the machine for other operations. i'lne series of tacl; pockets is arranged oblique to the other so that the extent of movement of the rerei ing plate to position all its pockets in alinenient with the tubes in the conductor plate and discharge the tacks mav be difl'ro ent from the spacing between the new in the conductor plate. A different number of tacks mav he ted in anv mult ple of the number of the raceway grooves. For actuating the separating devices to take from the rareiravs two charges of tar-ks in each cycle the pin on 168 which formerlydirectlv reciproratrd the separating devices meshes with a pinion 170 of half the number oi teeth which has a crank connected to the block 75% in the depending for]: of the separator driving bar I74 and from which that bar and the separating devices receive a complete reciprocation from the osc llatory movrment of the pinion 16S and the hopper inone direct on and a second complete re riprocal'ion from the oscillatorv movement in the other direction The crank block has a stnd 175 arranged to Contact at times with an arm 176 on a shaft 178 that has a tooth 179 having a vield ng connection with the delire'r'r slide bv moans 0F spring plungers 1 0 as shown in Fig. 9. Th s arrangement is such that as the stud 17:? turns clownwardlv and to the left in Fig. 9 it leaves the arm 176 and the delivery' slide 164 at rest in n hat mav be considered to be the discharlring position of the slide until the stud nearlv completes its rotary stroke when it will reach a position to contact with the upper side of the arm 17?) and more the delivor v slide into its first receiving position shown in Fig. 7, in time to talre the first set oi tacks discharged from the oblique slots and eyes of the separating plate 160.
