41 Claims.

In, its broad aspects, the present invention relates to machines which are. used in"'the manufacture of shoes to apply a. reinforcing strip to a shoe upper part comprising either a sheet of pliable material or the quarters joined by a back seam. More specifically, the'present .invention relates to machines which'arused to apply tape to that portion of the flesh face of a shoe upper part which is to be provided with a row 'of holes each forming or receiving one elementof a closure. In some shoesthe holes receive buttons, in others hooks, and in others eyelets. In the shoe industry the area in which the row of holes is to be formed and which is to be taped prior to the hole forming operation is-called the button row, the hookrow or the eyeletro'w, depending upon the type of closure'with which the shoe is to be provided. For convenience the phrase eyelet row is used herein to designate the taped area irrespective of the ultimate use of the row of holes to be formed therein.

Usually the eyelet row is covered by a piece of tape placed alongside but without the piles of the folded margin of the shoe upper part.- Usually the folded margin-has a bent run extending along at least one end of the eyelet row. It has been proposed heretofore to provide these tapeapplying machines with devices for perinitting the work to be swung laterally by the operative during the tape-applying operation in order that'the tape may be applied on a curved line along the bent run of the folded margin forming the termination of at least one endof the eyelet row.

One of the principal objects of the present invention is to produce a tape-applying machine which will shape at least one edge of the reinforcing stay so that it will fit the bent end on at least one end of the eyelet row.

Another of the principal objects of the present invention is to produce a tape-applying machine which will apply uniformly to successive work pieces a predetermined length of tape.

To the accomplishment of these objects, and such others as may appear hereinafter, the various features of the present invention reside in certain devices, combinations and arrangements of parts hereinafter described and then pointed out broadly and in detail in'the appended claims,

- possessing advantages readily apparent to those skilled-in the art. a

The various features of thepresent invention will be readily understood from an inspection of w 55 the accompanying drawings illustrating the best patent to Osgood, 1,54

Fig. 11 is a detail view in perspective of the tape-severing knife and its supporting lever, and Fig. 12 is a detail view in right side elevation, partlyin section, of thetape-guide and the tapesevering knife. Referring now to Fig. to' which the reinforcing strip is to be applied is shown as a shoe upper part ll provided with a folded margin l5. That portion of the flesh face: .of the shoe upper part H, which is the face exposed to view in Fig. 4, and through which a row of holes is to be formed to receive buttons, hooks or eyelets, is called herein the eyelet row. As shown in Fig. 4 the eyelet row is covered by a piece of tape 16 placed alongside but without the plies of the folded margin. The folded margin l5 has a straight run I'I. along one side of the eyelet row, a bent run l8 along one end of the eyelet row, and abent run 19 along the other. end of the eyelet run. The tape I 6 is applied to the eyelet row with one longitudinal edge ",en-

gaged with the straight run l1, and withshaped ends 2| and 22, engaged, respectively, with the 50 bent runs and I9.

The machine herein shown forapplying tape II to the eyelet row (Fig. 4) is similar in many respects to the taping machine illustrated in the 4 the pliable material I 9,376, August 11, 1925. 5

The applying of the tape it to the eyelet row is accomplished by the combined action of the roll work support 23 (Figs. 1, 2 and 5) and a pressing member 24. The pressing member 24 is secured to a head member 25, or lever, which has a vertical movement and also an oscillating movement. The oscillating head 25 is mounted on the main frame 26 of the machine and it receives its oscillating movement from an eccentric (not shown) on a driving shaft 27 carried by the main frame. The head 25 is provided with a slot 28 (Fig. 1) through which extends a stud fast on the main frame 26, said stud having a block 29 (Figs. 1 and 9) which is slidably mounted in the slot 28 and is journaled on the stud.

' As the shaft 2'! is rotated the eccentric thereon gives the head 25 an up and down movement and also a rocking movement. said movements causing the face of the pressing member 24 to move toward and from'the work on the work support and also to having a rocking or rolling contact with the work.

The work isguided into the machine by a guide 3t arranged to engage the external edge of the shoe part it which is parallel to the straight run -28. The tape is guided to the work by a tapeuide 2!. a Y

The tape is coiled in a roll (not shown) constituting the sourceof supply. From the coil the tape passes through an eye 32, (Figs. 1 and 2) and then under a flanged drum or roll 33, the

milled surface of which engages the sticky face of the tape.

The drum 33 is loosely mountedon a stud 32 which is screwed into the head 23. One race of the drum 33 is provided with a ratchet 35 which is held from movement in a, clock-wise direction by a spring-pressed pawl 35. From the drum 33 the tape passes over a take-up roll or feeler 3T! which engages the tape on its nontacky face. The take-up is loosely mounted on a stud projecting laterally from an arm 38 (Fig. 1) loosely mounted on a stud 39 projecting laterally from a bracket 49 (Figs. 2- and 9) bolted to the leftside vertical face of the frame 26. Fromthe roll 31 the tape passes under-a roll 4| free to rotate.

, vided with a hub 45 which rotates loosely on a stub shaft 46 projecting laterally from a bracket 41 (Figs. 2 and 7) projecting to the left from the machine frame 26 above the bracket 40. The drum 42 is' prevented from rotating baickwardly by a spring-pressed pivoted pawl 48 carried by a bracket 49 secured to the bracket 41. The pawl 48 engages a circular series of teeth 50 formed on the right-hand side of the drum 42. l

From the drum 42 thetape passes over a flanged idler 5| (Fig. 1) 'journaled on a stud 52 projecting laterally from an ear 53 formed on'a plate 54. The plate 54 is secured to a block 55' (Fig. 9) an extension of which is secured to the bottom of the bracket 40. From the idler 5| the tapepasses under a flanged idler .56 journaled on a stud projecting laterally from the downward and forward extension of the plate 54. From the idler the tape passes over a flansedidler 1 W- -2) in the stud 65.

naled on a stud .59 projecting laterally from a by two screws 62 adjustably to the downward and forward extension of the plate 52.

From the idler 58 the tape passes 'to the tapeguide 3i. The bottom of the tape-guide 32 com-- prises a curved plate 63 (Fig. 12) the opposite longitudinal edges of which are bent upwardly to form a channel through which the tape passes. The channel plate 63 is provided with ears 66 which are received loosely by a stud (55 (Figs. 10 and 12) projecting through a. plate E56 (Fig. i) which depends from a block supported from the bracket. 40. The tape-guide plate 63 is provided also with ears 6'8 (Fig. 12) to which is trunnioned centrally a tension device 68 having at one end a jaw to engage the tape and press it yieldingly against the plate" 63 and having at its other end a tail to facilitate the elevation of the jaw from the tape by the operative. The tape-guide 3i. is

' rotatable on the stud 65' but is held from move ment longitudinally'thereon by a latch (59, pivotally mounted on one side of the plate (53, the free end of which engages a peripheral groove 712 (Fig.

From the construction described it is apparent, as the drum 33 is free to rotate in a contra-clockwise direction viewing Fig. 1, that during the feed of the work over the work support 23 by the pressing member 24 there is a tendency for-the pressing member to. pull tape from the source of supply at each feeding step. But as the tacky face of the tape in the source of supply is stuck somewhat to the non-tacky face in an adjacent convolution, considerable force is required to unwind "the tape. it is, therefore, undesirable to rely upon the pressingmemberfll to pull p'e from the 'sourceof supply as the pulling force exerted thereby would drum-head the tape between the work and the tape-guide 3i and thus interfere With the application of the tape to the work.

In the illustrated embodiment of the present invention the roll 33 is rotated in a manner presently to be described to unwind the tape from the coil in the source of supplyand to produce an auxiliary supply of slack tape which is used up as needed by the pressing member 24. ,The

take-up engages the slack tape under the mild tension of a coiled spring H (Figs. 1 and 2) one end of which is secured to a pin on the arm 38 and the other end of which is secured to a bracket 12 on the main frame located between n 1ents of the presser member thestud 3-9 loosely carries a pawl 13 (Fig.1). The hubs of the, arm

38 and the pawl 13 interfit beneath. the idler 4 I, there being a space between the hubs'to allow the take-up .fland the pawl II to move relatively. Coiled about the hubs oi the arm 38 and the pawl 13 is'a spring 14 one end of which engages the arm 38- and the other end of which 1 engages the pawl I3.

Fig. 1, in constructionlines, shows the pawl I3 withdrawn from the orbital path of the ratchet Ii. Thil is due to the position of. the take-up or feeler '31 which is held in engagement with theloop of withdrawn tape by the light spring II. In consequence no tape is pulled from the the ratchet 35. Then as the ratchet 35 continues to move downwardly and laterally the pawl -I3 rotates the ratchet 35 and the roll 33 to draw tape from the coil in the source of supply. During the movement of the ratchet 35 in engage- 'ment with the pawl I3 thespring I4 enables the .of operationthe withdrawn tape is'bound to; accumulate. But as the spring II maintains the take-up 31 engaged with the withdrawn tape.

pawl I3 to yield relatively to the take-up 31. Thus, rotation of the pull-off 33 does not increase the tension of the take-up 31 on the tape engaged thereby- In order to prevent the ratchet 35 from riding over the pawl I3 during the movement of the head 25, a-bracket I5 is provided which carries an adjustable screw," for limiting the move ment of the pawl I3 into the orbital path ofthe ratchet 35. I In order to control the pull-off stroke of the pull-off 33 the pawl "I3 is made in two parts 11 and 18 so that they may be adjusted longitudinally through the screw and slot con-' nection I9. The selected adjusted position of the parts 11 and I8 is maintained by a drift 80, herein shown as a wedge block, interposed between-the head of the pawl I3 and one end of the part- I8. I r

In the illustrated embodiment of the invention the stroke of the pull-011.33 is such that more tape pulled from the coil in the source of supply in a single stroke thereof than 'is used up by the pressing member 24 in a single feeding step thereof. With such a construction andmode during its accumulation, the pawl 13 is withdrawn from theorbital path of the ratchet 35' and the operation of the pull-off 33 suspended.

When the pressing member 24 eats into the accumulation of withdrawn'tape the pawl I3 is replaced in the orbital path of the ratchet 35 and the pull-off 33 is rotated again to withdraw more tape. In the preferred mode of operation the pull-off 33 operates in timed relation with the pressing member 24 during successive cycles varying in number depending upon prevailing conditions and then the operation of the pull-off 33 is suspended for one cycle, or, it may be, successive cycles, .depending'aga-in on the prevailing conditions. Thus, while-the pressing member 24 is operated periodically, the pull-off 33 is'operated non-periodically.

When no work is in the machine the tapeguide 3| stands in the position shown in Fig. 1. During the application of the tape to the work the tape-guide3l stands. in the position shown in Fig. 5. In order to rotate the tape-guide 3| on the'stud 55 to transfer it from the position of Fig. l to that of Fig. 5 and to lock it in operating position the'left-hand side of the flanged tapeguide plate 83 is provided with a hole which engages a pin 82 (Figs. 10 and 12) projecting laterally from a lever 83 (Figs. 10 and 12) pivoted on the stud 65. The front end of the lever 83 is secured rigidly to one end of a lever 84 (Figs;

- 92, between the. frame 25 and the arm 9|.

1 and 10) pivoted on the stud 85, there being a distance piece 85 on the stud interposed between the lever 84 and the plate 85. The other end of the lever 84 is connected by a heavy coiled spring 1 and 9) the sides of which embrace the shank of a screw of an arm..9'|. The arm 9| is secured toone' end of 'a rock-shaft 92 journaled in the frame, a distance piece .93 being interposed, on the rock-shaft The other end of'the rock-shaft 92 is provided with an arm 94 (Figs. 2 6 and 9) which is pivoted to the upper end-of a plate 95. The lower end of the plate 95 is pivotally connected to a bar 93 I which is carried by one end of a lever 9'1. centrally pivoted on the machine frame. The other end of the lever 91 is provided with an inclined slot 98' thewalls of which embracea cylindrical block 99 (Fig. 9) carried by the bent end I00 (-Fig. 2) of a rock-shaft IOI. Therock-shaft I0| is provided with an arm I02 suitably connected for control by the operative to a treadle-rod I03.

Downward movement of the treadle-rod I03, through the connections described, rotates the rock-shaft 92 inv a contra-clockwise direction (Figs. 1 and 5) depresses the link 88 and rotates I the tape-guide 3| on the stu'd'65 from the position of Fig. l to that of Fig. 5. In order to lock the tape guide in operating position the link- 88 is provided with a block I04 (Figs. 1 and 5) which,

* projecting'laterally from one end when the tape-guide 3| is in.the position of Fig.

.Leng'ages a rearedge on the vertical arm of a bell-crank lever I05 pivoted on the plate 54. The vertical arm of the,,bell-crank lever I05 is pressed into engagement with the end of the block I04 by a coiled spring I08 interposed between the armv and a block I01 secured to the plate 54. The' lower end of the arm is provided with a shoulder I08 which, when the'block I04 is carried downwardly by the link 88 under the influence of the treadle, engages overthe upper forward corner of the block I04 and latches .the tape-guide 3| 'in itsoperating position against the tensionof the spring 86. The slot 89' allows the operative to release the treadle as soon as the tape-guide 3| is locked inits tape-applying position. 7

As indicated in Figs. 1 and 5 the machine is provided with a knife I09 for severing the tape at i a point between the work and'the delivery end of the tape-guide 3| when it is in the position of Fig. 1. The knife comprises a curved plate I I0 (Fig. 11) havi ng a front serrated cutting edge III. The rear edge of the plate 0 is secured to a bar 2 which is carried by a clamp-block H3. The block 3 is secured to the vertical arm of a bell-crank lever I|4 pivoted on the plate 66.]

The horizontal arm. of the belhcranklever H4 has a cam upper surface 5 which, when the parts are in the position of Fig. 1, is engagedby' a button. 5 .(Flgs. 1, 5, 9 and 12) rotatably mounted'on'one end of a horizontal rod II I slidably mounted in the head 25. With this con- ,struction, when' the parts are in the position of Fig. 1, movement of the head 25 to actuate the presser member 24 causes the button 6 to wipe along the cam surface I I5 and thus operate the knife to sever the tape. The knife I09 is returned to its inoperative position; when the'butto'n H6 ls elevated by the head 26 away from the cam surfaceIIS, by a coiled spring (Fig. 12) one end of which is connected to the plate 66, and the other end of which is connected to an eye formed on the bell-crank lever M8, the plate66 being provided with a pin M9 (Fig. 12) to limit the movement of the knife 809 under the influence of the spring 808. When the parts are in the position of Fig. 5 the button H6 is held in a position clearing the cam surface H5, during the reciprocating and oscillating movement of the-head 25, by a leaf spring I (Fig. 9) one end oiwhich is secured to the head and the other end or which presses against the free end of the rod H1.

When the parts are in the position 03 Fig. l the button 8 it is forced to the right and-directly over the cam surface lit by a cam i2I (Fig. 9) formed on one end of a bell-crank lever [I22 (Figs. 1 and 5) pivoted on the plate 56. The lower end of the bell-crank lever 622 is embraced by pins I23 and ld lon the lower end of the link dd, the bell-crank lever being held in engagement with the pins by a coiled spring I25 one end 05 which is secured to the plate 58 and the other end oi which is secured to a bent plate i120 pinned to the bell-crank lever 62?.

With this construction, when the link 88 is de- I pressed to lower the tape-guide 3| intooperative position and to lock it in that position, the cam l2l is withdrawn from the button lltthus to I maintain the tape-severing knife inoperative during the tape-applying operation. When the link tion of Fig. 1 and throw the knife into operation to sever the tape, by any suitable devices under the control ofthe operative. To relieve the operative of the additional manipulations and to insureuniformlty in the lengths of tape applied successively to similar work pieces, it is preferred, however, to control the latch automatically. In order that'a predetermined length of tape may be applied 'to the work, devices are provided for determining the extent to which the tape may be drawn through the tape-guide preparatory to the operation of the tape-severing cutter. Preferably these devices are connected with .the latch I00 so that their movement, when the proper amount of tape is drawn through the tape-guide, trips the latch and thus throws the actuating mechanism for the tape-severing knife into operation. The devices are thus rendered active at the proper time without any attention on the part of the operative.

.As shownln Figs. 1, 5 and '1 the tape is led towardsthe tape-guide 3| over the drum 42 which is mounted to turn freely on the stud 48 and also upon the periphery of a controlling or measuring wheel I21 rotatably mounted on a sleeve I20 carried-by the stud 46. The. measuring wheel carries a clamping jaw or tooth I23 mounted to engage one of a series of teeth I formed on the lefthandside face of the drum 42 and thus clamp plate 54.

is formed on one end o1 a link I 3| mounted to slideloosely through a block I32 secured to the measuring wheel I21. The other end of the link i3I rides in a slot I34 formed in the upper end of a lever I35. The link I34 carries a lateral pin I36 the opposite ends of which are provided with nuts I31 engaged with the lever 635. The lever I is pivoted on a pin I38 bridging the space between a palr'of ears I 39 formed on the block I32. The tooth I29 is pressed into engagement with one of the series of teeth 539 by a spring I40 coiled about the link I38 and interposed between the block 532 and a collar Ml on the link Q38.

- In order to withdraw the tooth 629 from the drum 42 the lower end of the lever M355 is engaged by one end of a screw I 32 carried adjustably by one end of a long lever I43. Intermediate its ends the lever lfl3-is pivoted on a vertical pin Mt (Fig. 2) bridging the space between the ears N5 of a block Mt secured to the upper edge of the The other endof the lever M3 is provided with a roll M1 (Figs. 1, 2 and 5) which is held by a coiled spring M5 (Fig. 2) interposed be-, tween the lever I63 and the block M6, in engagement with a cam plate I59 carried by the link 85.

When the parts are in the position of Fig. 1 the cam plate M5 p esses the roll I61 in a direction to cause the lever M3130 withdraw the clamping jaw I29 from engagement with the drum 42. When the treadle-rod 803 is depressed by the operative to lower the link 88, the roll M1 rolls down the incline on the cam plate. N9. thus releasing the lever 535 so that the spring M0 may press the clamping jaw I29 into engagement with the drum 52. Thus during the tape-applying operaguide 3! causes the drum 42 and the measuring wheelI21 to move together as a unit. During this movement a spring I (Fig. 7), having one end connected to a support I5I pinned to the sta tionary stud Q6, and. having its other. end connected to a rod. I52 projecting laterally from the measuring wheel I21, is wound up so that the measuring wheel I21 may be returnedto its original position when the clamping jawIZS is dis,-'

.under the influence of the tape is limited by a stop I54 (Fig. '7) having a knurled and slotted head I55 and a threaded shank I56. The shank I56 is pro videdwith a washer I51 which is interposed be-- tween the stop I54 and a plate' I58 rotatably mounted on the stud 46. The shank I56 passes through the plate I58, a circular slot I59 (Fig. 5 formed in the measuring wheel I21, and a plate I60 rotatably mounted on the sleeve I28. The

' threaded end of the shank I56 is provided wlth'a With this construction the position 01" tion, the drawing of the tape through the tapethe stop I 54 with relation to the measuringwheel 7' I21 may bev aried within the limits defined by the ends of the slot I59 and the adjusted position of the stop I54 maybe retained by manipulating the knurled head I55 to clamp the measuring wheel I21 and the plates I50 and I60 together.

During the tape-applying operation, the drum 42 and the measuring wheel I21 rotate in unison in a clockwise direction (Fig. 5) until the stop I54 engages under the hooked end I020 on the cutting out of a predetermined length of tape from the continuous length of tape leading from the source of supply so far described, are equally well suited to taping machines for applying a reinforcing strip to pliable shoe part material and to combine seam-pressing and taping machines for applying a reinforcing stripto the seam-ridge,

formed by joining the quarters of a shoe up'per, prior, during, or subsequent to the seam-ridge pressing operation.

In order to apply the tape I6 (Fig. 4) in a straight run to the eyelet row it is necessary to shape the leading and trailing edges 2I and 22 of the strip I6 so that they fit,-re'spectively, the bent runs I8 and I9 of the folded-margin I5. To this end the machine is provided with a die I62 (Fig. 8).

I 63 and I64 formed, respectively, ontwo plates I65 and I66 secured to ,a" block I61 mounted to slide on the block {I55 (Fig. 9). As shown in. Fig. 8 ,the plates I65 and I66 meet in a miter. joint.' Thus the cutting edges of the die cut from the tape a polyhedron, specifically, a triangular prism, forming in the bodyportion of the tape 1 adjacent one longitudinal edge thereof a reenformed by the snipping knifeoi the folding ma chine. In consequence the die I62 is shaped to make two straight converging cuts in the tape.

forming a diedral angle therein having the .ver-

be curved. In such cases the angle between the cutting edges of the die I62 will be curvilinear. The vertex of this curvilinearangle will bear the same relationship tothe longitudinal edges of the tape as the diedral angle edge I61.

The die I62 operatesin a way formed between two cutting blocks I66 and I69 having, with relation to the cutting edges I63 and I64, internal and external shearing edges I16 and HI, respectively. The internal shearing-edge, block I68 is formed on a base I12 (Figs. 8 and 9) secured to the block I55. The external shearing edge block I69 is secured to the base I12. As indicated in Figs. 2 and 9 the tape is led over the shearing edge blocks I68 and I69 beneath a forked strip-' per'plate I13 secured to the block I69.

In order to actuate the die I62, the block I66 is secured to one end of a plunger I14 (Fig. 9) mounted to slide in a cylinder I15 carried by aplate I16 secured to the block I55. The die I62 is normally held in an inoperative. position b a spring I11icoiled about the. cylinder I15 and nterposed between the plate I16 and a collar I18 secured to the plunger I14, The free end of the This die is composed of two cutting edges operation, the plate 95 is elevated, as indicated in Fig. 6, thus causing thelever I19 to operate the plunger I14 and force the die through the tape.

As the die operates on the sticky face of the tape thepolyhedron cut out of the tape sticks to the cutting edges of the die I62 and is retained in the angle between the plate'sI65 and I66. When .the die is actuated again to out another polyhedron out of the tapethe uncoated face 01' the polyhedron previously cut out isv stuck to the sticky face of the polyhedron being cut out so that they are both retained in the angle between the plates I65 and I66. This action is repeated with the result.,thata stack of stuck together polyhedrons gradually forms in the" angle between the plates I65 and I66finally working out through an opening 'I85 (Figs. 2 and 8). from which the stack may, project fora considerable distance without danger of disintegrating' In order to correlate the cuts made by the die I62 with the cross out I86 '(Fig. 3) made .by the knife I69 so that the cut I86 will intersect the vertex or diedral angle edge I61 and thus shape both the leading and trailing edges 2I and 22 of the predetermined length of tape, the length of the tape in the machine extending from its leading edge 2I .(Fig. 1) back to the line of junc-'- ture between the cutting edges I63 and I64 should be'a multiple of the predetermined length of tape to be applied to the work. This multiple distance, within limits, may be obtained or varied as desired by adjusting the positionof the plate 66, carrying the roll- 59, through its slot and screw connection with the plate 54. For instance, if the predetermined length of tape to be applied to the work is to be one inch the length of tape extending from the leading edge 2| (Fig. l) to the center of the die I62 may be six inches. If the predetermined length of tape to be applied to'th'e work is to be one and one-half inches no adjustment of the plate is necessary. It would, however, be necessary to shift the position of the stop I54 so' that after a stretch of tape one and one-half inches long-had been fed past the drum 42 the stop would engage under the hook I626 and trip the latch I68.

' To operate the'machine the operative adjusts thepositions'of the stop I54 and the plate 66 to accommodate the machine to the particular I the position of Fig.5, the leading edge 2I into the angle formed between the eyelet row and the bend I8. Immediately after the treadle-rod I63 has been depressed it is released. In addition to lowering the tape-guide into its tape-applying position the depression of the treadle-rod I63 ac- 'tuate's the die I62 to take a bite out of one edge of the tape, throws the tape-severing knife I69 out. of operation, clutches the measuring wheel 421 to the drum 42, and operates the latch I68 to retain'the tape-guide and the measuring wheel I21 in operation and the tape-severing knife out of operation.
