MACHINE FOR APPLYING REENFORCING STRIPS TO ARTICLES OF FOOTWEAR.

Application filed January 12, 1923. Serial No. 612,307.

To all whom, it may concern:

Be itknown that I, 'LEwIs J. BAZZONI, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Applying Reenforcing Strips to Articles of Foot- Wear, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to mechanism for making a reinforcing strip .and applying it embodied in a machine for making such a strip and applying it to an article of footwear such as an arctic.

In the manufacture of arctics it is customary in some factories to apply along the top and front edges of the quarter a reenforcing strip which comprises a piece of tape folded double, usually with a cord enclosed in the crease or apex of the fold.

Hitherto the making of the strip and ,the

applying of it to the upper of the arctic have 7 been done by hand; and the general object of the present invention is to provide a machine which will perform both'operations.

According to one feature of the invention the tape is folded approximately along its.

longitudinal middle, a cord is directed into the apex of the fold, and the cord and folded tape are pressed together to form the reenforcing strip. In the illustrative meehanism the tape is drawn progressively through a stationary folder by combined feeding and pressing rolls, the cord being introduced into the fold at a locality in advance of'that ention of the parts of the machine, a general de- 40 gaged by the rolls. According to another feature of the invention, the reenforcing strip, as fast asit is made, is applied to the arctic or other article. In the illustrative machine the leading end of the strip is led up through and out upon the surface of a table where the operator places upon it the margin of the leading end of the arctic-upper, the work,

' which includes the strip and the arctic upper, being fed progressively to. work-pressing mechanism including a hammer which presses the strip firmly into place. The tape herein to an article and is herein illustrated as illustrated is that commonly used in rubber shoe factories and consists of so-calledfriction fabric which is coated or impregnated with unvulcanized rubber. Such fabric is tacky and requires no cement either to hold the fold in shape or to hold the strip to the arctic. 1 y

7 These and other features of the invention combinations ofparts will be described as I Fig. 1 is a side elevation of a machine in which the present invention is embodied, certain parts of the frame having been broken away. i

Fig. {I is a similar detail showing the same parts in ariother position, a piece of Work Fig. 5 is a perspective of the Working parts i of the machine.

Fig. 6 is "aplanf of the mechanism for scription of its mode of operation will be 1 given. Tl1e purpose of the illustrative machine is first to make a reenforcing strip by folding a piece of tape along substantially .its median longitudinal line, running a cord into the crease or apex of the fold and then pressing the cord and folded tape, and second to apply the reenforcing strip thus formed to the margin of an article of footwear such as an arctic.

The tape is led from a reel 11 (Fig.'

2) through a folder the cover of whlch is 60 I including certain details of construction and I indicated at 13 (Figs. 5, 7 and 8) which, as

1 by means of two feed rolls 17, 19 which act not only to feed the reenforcing strip thus formed but topress the sides of the folded v tape together and to press the vertex of the fold about the cord. The manner in which this is done is shown best in Fig. 9 in which it will be seen that th cord is at one side of the plane which separates the wings of the fold in the tape, the locating of the cord in this position being made possible by the presence of a groove 21 in the lower part of the roll' 19. The reenforcing strip thus formed is led (Fig. 1) between guide rolls 23, and then up through an inclined slot in the work table or Support 25. On the work support the strip lies at one locality between upper and lower feed members 27, 29 (Fig. 4) and at another locality beneath a if presser in the form of a hammer 31. The

margin of an arctic or other-piece of fo'otwear is now laid on the reenforcing strip and the'tWo are fed in unison by the feed members in the direction indicated by the arrow and are pressed together by the hammer. When the desired length of strip has thus been attached'to the margin of the arctic,-the' free portion of the strip is severed from the attached portion by a knife 33 (Fig. 5) which is caused to move up through a slot in the table 25. The margin of the upper of a second arctic may now beplaced upon the end of the strip and the strip-laylng and attachingoperation repeated. With thisbrief outline of the mode of operation of the machine, a detailed descriptlon of its constructionwill now be given.

- Referring first to Figs. 7 and 8, the folder comprises a base 35 which rests in a guideway formed on a support 37, said support "being carried by a post 39. The folder is heldin adjusted position in the guideway by a bindlng screw 38 (Fig. 8). The top of the folder is constituted by the cover 13,

referred .to above, which is pivoted to the base at 43, said cover having at its forward end a downwardly inclined guide to di-' rect the cord 200 into the bottom or apex of the fold in the tape. 'The passageway inthe base, through which the tape is drawn, is

fwide enough at its receiving end to permit the tape to lieflat. This passageway grows narrower and changes in shape until at its delivery end it forms with the downward projection on the delivery-end ofthe-cover a U-shaped guideway 47, as shown in Fig. 7.

The tape, bent or folded into this U-shape and with the cord inthe bottom of the U, is delivered to the bite of the pressing rolls 17, 19 (Figs. 5 and 6) which are carried respectively by vertical shafts 48, to the lower ends of which are fastened respectively gears 49, 51 which mesh with each other. Carried by the shaft 48.is a ratchet 53 engaged by a 'pawl 55, said pawl being pivoted at 57 to an arm 59 and heldv in engagement with the ratchet by a sprin 61. The arm has at its right-hand end a s eeve 63 loosely mounted on a vertical post 65, said sleeve, as will presently appear, having integral with it the lower feed member 29. Pivoted to the left-hand nd ofthe arm 59 is one end of a link 69 to the other end of which is pivoted an armi71, the hub of which is fast to the lower end of a vertical rock-shaft 73. Fast to the upper end of this rockshaft is the hub of asecond-arm 75 having mounted on its upper side a roll 77 which projects into a cam groove 79 formed in a barrel cam 81 which is fast tothe driving shaft 83. With this construction it will be evident that rotation of the shaft 83 rocks the vertical shaft 73 and, gthroughthe link (39 and arm 59, causes the pawl 55 to turn the ratchet 53 intermittently. The presser rolls 17, 19. are thereby turned in the same manner to press the reenforcing, strip and to advance it. The shaf-t. 50, by which the presser roll 19 is carried,is mounted in an arm 85 the hub ofwhichiis pivoted on the post 39, the outer end of the arm projecting beyond the shaft50 and having pivoted to its outer end at 86. one end of a link 87 which extends into a casing, 89. The outer end of this link has ahead between which and the cap 91 of the casing is held a coiledspring 93. The'casing has a curved tail which is pivoted at. 95. to -a hand lever 97, said lever beingpivoted'at 99 to anarm 101 the hub of whiohi's pivoted on the shaft 48. Also mounted onthe pivot 99 is a detent 103 which is held ingengagement with the ratchet 53 b a'spring (not shown). By reason of the re ative ositions of the pivots 88, 95 and 99, the spring 93 normally urges the presser rolls 17, 19 toward each other. When it is desired-to; separate these rolls in order, for example, to introduce the leading end of the reenforcing strip between them, the hand lever-.97. is swung'in a'ycounterclockwise direct'ion asn viewed in Fig. 6.

As has been explained, *thejreenforcing strip, after it has been pressed between the rolls 17 19, is led 'up'through'jand upon the top of the flat work support- 25. At this stage the margin ofthe arctic .or other article to which the strip -is'-Itof 'be applied is laid on, the strip in the manner shown in Fig. 4, the work, including the strip and the arctic. being fed in the direction indicated by the arrow, by upper and lower feed members 27, 29 beneath the hammer 31. The oscillation of the lower feed member 29 through the arm 59, link 69 vertical rockshaft 73 and arm 75 has been described. It is, of course, desirable that the upper feed member 27 should oscillate in unison with the lower feed member, it being understood that such oscillation takes place when the members are gripping the work as shown in Fig. 4. In order to cause oscillation in unison of the two feed members, the arm 7 7 (Fig. 5) has a socket in its end remote from the rockshaft 73 to receive one end of a rod 105. the other end of the rod carrying a lated in a forward direction to feed it. then release the work and finally are oscillated in a rearward direction thus completing the cycle. The mechanism for oscillating them has been described. Relative movement of approach to cause them to grip and to release the work at the proper times is brought about by lowering and raising the upper member 27. Loosely mounted on the stem 111 of this member is a headed sleeve'113, between the head of which and the top of the hub of the arm 109 is a coiled spring 115. Resting-upon thetop of the head of the loose sleeve 113 are the arms 116 of a bell-crank lever 117 which is pivoted to the frame of the machine at 119, the downwardly extending arm of the bell-crank lever carrying a roll which runs in a track in a barrel cam 121, fast on the driving shaft 83. Fast to the stem 1110f the upper feed member 27 and located above the arms 1160f the voke is a collar 123. Thus, when the shaft.

83 is rotated the two feed members are oscillated in the manner which has been described, and the upper feed member is forced down yieldingly through the spring 115to press the work against the lower feed member 29 and is raised positively by contact of the upper surfaces of the arms 116 of the yoke with the collar 123. The oscillations and relative movements of approach and separation of the feed members are so timed that the work is fed intermittently in the direction indicated by the arrow in'Fig. 4. The rod 105 is in two .parts connected by a turnbuckle 125 so that its length can be varied when the machine is assembled. The ball 107 at the righthand end of the rod is heldin thesocket in the hub of the arm 109 by a'set-screw 127 which is-locked in adjusted position by a nut. This construction enables the arm to swing up and down with the reciprocations of the stem 111.

The hammer or work prescer 31 (Fig. 1) is carried at the lower end of a stem 131 which passes through alined bearings 133 in the frame of the machine, said stem having fast to it a frame 135 carrying two spaced rollers 137 between which is located a cam 138 carried at the outer end of the driving shaft 83, "rotation of the'cam there-' by causing reciprocation of the hammer. Cooperating with the hammer (Fig. 3) is an anvil 139 which is located in an opening in the table and supported upon a coiled spring 141.

The mechanisms for operating the feed members and the hammer are so timed that the work is seized andfed forward while the hammer is in raised position. The hamm'er descends to press the reenforcing strip againstthe work the feedmembers release 1 the work and swing back into position to some it again, the hammer rises and the cycle begins once more.

After the desired extent of reenforcing strip has been applied to the arctic, the strip must be cut off. To this end an opening is provi-dedin the table at one side of the feed members through which the knife 33, re-

ferred to above, may be projected when desired; and extending over the opening, as best shown in Fig. 3, is a. combined strip guide and cutting block 143. The knife 33 (Fig. 5) is fast to one end of an arm 145, the other end of which is pivoted at 147 to the frame of the machine. Pivoted to the arm intermediate its ends at 149 is one end of'alink 151 to the other. end of which is pivoted at 152 a block 153, said block being received in a guideway formed in an arm 155 which is fast to the end of a rockshaft 157. This shaft is rocked continually through an arm 159 the hub of which is fast to the shaft and the outer end of which is pivoted at 161 to the lower end of arod 163 the upper end of which carriesan eccentric strap 165 surrounding an eccentric on the drive shaft 83. Normally the axes of the rockshaft 157 and the pivot 152 are held in alinement so that no reciprocation is imparted to the knife 33. When it is desired to reciprocate the, knife. in order to sever the reenforcing strip at the end of the strip-laying operation, the block 153 is moved in the slot horizontal rod 173. Integral with the other.

end of the sleeve is a second arm 17 5 having pivoted to its outer end the upper end of a treadle rod 177. The treadle rod 18. normally held up in the position illustrated by treadle (not shown) is depressed to pull the treadle rod 177 down, the arm'169nsrocked; in a clockwise direction, as vlewed 1n F g. 5,...

to cause the knife tobe reciprocatedchain 181.

treadle rod 183 furnishes means for apply; ing power to the shaft 83 when desired.

In order to permit ready access to the driving mechanism, the whole frame of the machine, including the overhanging arm at the outer end of which the upper feed member 27 and hammer 31 are mounted. is pivoted about a rod 185 (Fig. 2) which extends along one side of the lower part of the machine and is carried by a substantially flat base plate 187. At the side of the machine opposite to that on which the rod 185 is I cated, the base plate 187 has an upstanding v has been removed and the lower one loosened lug 189 to which is pivoted a latch member 191 having upon its threaded stem two spaced nuts 193 between which is received an ear 195 which is machine, After t e upper of the nuts 193 and the two treadle rods disconnected, the whole frame may be swung about the rod In the operation that the tape and cord have been made into the reenforcing strip by passing through the folder and between the pressing rolls 17, 19,

and that the leading portion of the strip. has

. passed between the guide rolls 23 and'fup through the slot in the table 25, the leading end of the margin of the arctic vis placed. upon the leading end of the reenforcing strip, and the treadle rod 183 operated to throw in the clutch. The work including the. arctic and the reenforcing strip, is fed 'intermittently by the members 27 29 and is ham-1' mered or pressed .during the pauses in the intermittent feed movements'by the ham-1 mer 31. At the same time, more cord and tape are being folded and pressed so' that the reenforcing strip is supplied as fast as it is needed, it being understood that the strip-making mechanism and the work-feed ing and pressing mechanism are so timed I that the making of the. strip and the applying of it to the piece of footwear take place simultaneously in such manner that'one per tion of reenforcing strip is prepared while I another is being applied to the piece of foot- I I wear. At the end of the strip-applying o eration, the free end ofthe strip is broug t beneath the cutting block 143 and the treadle art of the frame of the.

177 depressed to cause the knife 33 to sever the strip.

In the manufacture of arctics, the parts ofthe buckles, that is the so-called tongues and ladders are attached to the upper before the-reenforcin strip is applied, one of the .t ladders being s own at 400 in Fig. 4. These members add considerable-thickness to the .zjworkin the-localities in which'they are pres- Loose on thedriving shaft 83 is a sprocket around which and around a sprocket fast to the shaft of an electric motor 179 runs 18..

A friction clutch of usual type controlled by a bell-crank lever 182'and aentand extendjfon a considerable distance "beyond thefmargini' In. order to rovide for thisjcondition, thefflat work -ta le- 25 has ness of the work at the localities in which the buckle members are attached interferes in no way with the feeding of theLw rk or' the applying of the strip.
