To all whom t mayI concern:

Be it known that I, CHARLES H. HoY'r, a citizen of the United States, residing at Beverly,` in the county of Essex and State of Massachusetts, have invented certain Improvements in Fastening-Inserting Machines, of which the following description, in connection with the accompanying drawings, is aspecification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to Vfastening inserting machines, the embodiment of the invention herein illustrated and described being particularly intended for the attachment of the heel ends of outsoles inthemanufacture of boots and shoes. yIt is recognized, however, that the invention asa whole and various features thereof are not limited in their application to the particular use illustrated, and that they may be usefully employed in other relations.

In the manufacture of boots and shoes, it is the usualpractice to attach the heel seat end of the outsole to the upper and insole by fastenings inserted about the periphery of the heel seat, and it has also been customary to utilize for the insertion of the fastenings, machines of the type which insert fastenings successively. Although such machines are commonly provided with a shoe support and means for automatically feeding the shoe past the point of fastening insertion and for guiding the shoe as it is fed, it is necessary in order to insure that the fastenings will be rightly disposed `with reference to each other and to the edge of the heel seat that the shoe be manipulated incertain definite relations to the parts of the machine during the driving of the fas'tenings. Such manipulation of the shoe requires the exercise of considerable skill and care-on the part of the operator.

It is anl object of the invention to'pro-` vide a machine forattaching heel seats which can be operated very quickly and easily, and the use of which will require a minimum of skill and care on the part of the operator. To this end I have devised a novel organization .including fastening inserting means of the type by which a number of fastenings are inserted in a piece of work in a single operatiomthe construction of the fastening. inserting devices being such that substantially no manipulation-of the work by the operator is called for. other than that required for the presentation of the work to the machine and its removal therefrom.

It has hitherto been proposed to attach heel seats by means of machines constructed to insert a lnumber of fastenings at a time.

So far as applicant is aware, however, such machines have invariably comprised a single die plate or the like having openings to receive fastenings for presentation to all of the drivers ofthe machine. Manifestly, if it were desired to employ such machines for attaching heel seats of different sizes and shapes, it would be necessary to modify the arrangement of the openings in the die plate and the construction of the plate in order to maintain the relation ofthe fastenngs l and the edge of `the heel seat uniform and properly to conform the edge `of the heel seat end of the sole to the edge of the-upper and insole- For this reason, it has been customary in the design of such machines `to mount the die plate in such a way that -it can be removed from the machine to enable a die plate of a different character to be substituted for it, when it is desired to adapt the machine for the attachment `of heel seats of different dimensions from those previous- .ly operated upon. The substitution of different forms of die-plates necessitates corresponding substitutions of the awls and drivers and other elements of the fastening inserting instrumentalities, thus rendering the adaptation of. the machine to operation on heel seats of varyingdimensions troublesome, in consequence of which such machines have not been used to any extent for attachin heel seats.

Mac ines have also been devised for inserting a number of fastenings substantially simultaneously which are provided with a been provided with mechanism operable to shape the heel seat end vof the sole to the upper and insole.

An important feature of this invention resides in a novel fastening organization of the multiple or gang type constructed for effective operation upon outsoles and including provision for relativemovement of different fastening mechanisms to position the fastenings, the machine herein shown as an illustrative embodimentA of the invention having a plurality of separate fastening inserting mechanisms and including means for applying conforming pressure tothe outsole. rllhe separate fastening inserting mechanisms in the construction shown are disposed correspondingly to the periphery of a heel seat and are made adjustable thus enabling applicants machine to be readily adapted for operation on work of different characteristics, inasmuch as the removal Vof any part of the machine and the'substitution of another part therefor is rendered unnecessary. 'llhe disadvantages attendant upon the use of prior machines of this type for the attachment of heel seats are thereby obviated. 1n the illustrated exempliication of the invention, each of the separate fastening inserting mechanisms comprises a throat having its under-side inclined downwardly and outwardly from its fastening receiving opening or openings for engagement with the tread face of a heel seat adjacent to its marginal edge to press the edge of the heel seat end of an outsole into close conformity with the edge ofan upper and insole.

1n accordance 'with a further feature the invention provides novel means of control for fastening inserting means,y the machine illustrated having means for automatically positioning the fastening inserting mechanisms to accommodate them to heel seats of different dimensions so as to cause the fastenings to be inserted in proper relation to the contour edgev of the heel seat and toenable the marginal edge of the heel seat to be accurately conformed to the upper and insole. ln the construction shown the arrangement of the fastening inserting mechanisms when a piece of work is in position to have fastenings inserted in it by said mechanisms y is determined b means for clamping the work. lln the il ustrated exemplification of the invention, the `work clamping means comprises a flexible band acted upon by moving parts of the machine to conform it to the work and operatively'connected to certain of the fastening inserting mechanisms on each side of the work. @ther fastening inserting mechanisms are provided on each side of the work, which are controlled by the clamping band independently of the firstnamed fastening inserting mechanisms. llt will be recognized that in' this as well` as other l features the invention in its more Lacasse general aspects is not limited to machines for fastening outsoles.

Other important features of the invention, including a novel construction of shoe end clamping means, will appear as the description proceeds and will be pointed out in the appended claims.

By Way of example, the invention is illustrated as embodied in a machine of the same general type as that .disclosed in United States Letters Fatent to llt. F. McFeely, No. 1,129,881, granted March 2, 1915, for improvements in machines for` use in the manufacture of boots and shoes. 'llhe machine comprises acolumn 2 having mounted thereon a head 4 crowned by a frame 6 upon which is mounted a hopper 8 for supplying fastenings to raceways 10 at the front of the machine head. The hopper 8 is operated by means of 'a rack 12 carried by a rod 14 which is reciprocated by a. cam (not shown) on a shaft 15 journaled inthe head 4. rllhe shaft 15 may l@be driven from a short shaft 16 by reducing gears of the character fully shown and described in the co-pending application of 1t. F. McFeely, Serial No. 115,230, filed August 16, 1916, for improvements in lasting machines. 'llhe shaft 16 may be operated as shown in Patent No. 1,129,881, and the operation of the shaft may be controlled by clutch mechanism of the character contemplated for the machine of the above-cited patent and fully shown and described in United States Letters Patent No. 7 91,986, granted on an application of R. F. McFeely, June 6, 1905. The clutch mechanism comprises a rod 18 adaptiso ' signed to insert fastenings of the kind generally4A denominated nails, and for convenience of description, certain features ofthe machine will be described by reference to their functions when the machine is used for inserting nails. It will be understood,

vhowever, that the term nail is used for purposes of exposition merely and not by way of limitation.

In accordance with the invention, the ma# chine is provided with a plurality of nail inserting mechanisms or limits, each comprising a throat and means -forndriving nails through passages in fthe throat. illustrated construction (see Fig. 3), there are provided a rear nail inserting unit 22 and two,l side nail inserting units 24 and 26 'on each side of the space defined by said units. As shown also, the throat 28 of the rear unit is formed with two nail receiving passages30, wheras each of the throats 32 and 34 of the side units 24 and 26 respectively, is provided with three nail receiving passages designated 36 and 38. It is manifest however, that'the number of nail receiving passages in the throats 28, 32, and 34 may be varied without departing from the principles of the invention,and that.

the number and arrangement of the nail inserting mechanisms or units may also be modified. The rear nail inserting unit 22 comprises a casting 40 carried by a plate 42 mounted slidably in the head 4 of the machine. The 'plate 42 is adjustably secured to the head 4 by means of ascrew or the like threaded into the plate and passingI through a slot 46 in the head. The casting 40 has apart 47 extending rearwardly therefrom and received in a channel 48 of the plate 42. Adjustment of the casting 40 relatively to the plate 42 is provided for by means of a screw bolt 49 passing through a slot 50 in the v'extension 47 into the plate 42. With this arrangement, the throat 28 maybe adjusted forwardly or backwardly on the machine head 4 in order properly 'to position the nail inserting until 22 for operation on heel seats of different dimensions.

For convenience of description, the nail inserting units 26 will be hereinafter sometimes termed the end units, and the units 24 will be referred to as the corner units.

A description of one of the end units 26 will suffice for both of said units, inasmuch 'as .they are similarly constructed. Likewise,

a descriptionof oneof the corner units 24 lspring 66 in a position determined by In the will sul'ce for both. lThe endunit 26 comprises a casting 52 formed `with a rearwardly extending part 54 adjustably secured to a plate 56 mounted for translatory movement in a guideway 5 8 of the head 4. As shown, the means for securing the casting 52 to the plate 56 comprises av screw 60 passing through a slot 62 in the extension 54.v The plate 56 is recessed at 64 (see Fig. 4) to receive a spring 66 interposedfbetween the rear wall of the recess and a pin 68 projecting int-o the recess. In the illustrated construction, the pin 68 yis carried by a plate 70 having a lateral projection 72 fitting into 'an' opening 74 in the adjacent wall of the head 4 of the machine.. From the foregoing,.it is apparent that the nail inserting unit 26. will normally b e maintained by the engagement of the pin 68 with the front Wall of the recess 64.

The corner unit 24 comprises a casting 76 carried by a plate 78 slidably mounted in a guideway in the head 4 (see Figs. 3 and 5). The plate 78 may be secured to the casting 76 in any suitable manner or may.

be formed integrally therewith. Preferably, and as shown, means -is provided for normally urging the casting 76 and the throat 32 mounted thereon toward the space defined by the nail inserting units. Conveniently, such means comprises a rod 80 on the plate 7 8 and a rack member 82 slidably supported on the rod, between Whichand a shoulder on the plate 78 is interposed a compression spring 84. lTo the end that the tension of thevspring 84 may be regulated, the position of the rack member 82 is adjustably determined by a pinion 86 meshing with the rack. The pinion 86 is supported by a bracket 88 secured to the head 4 by a screw7 or the like, 90. Rotationy ofthe pinion- 86 will effect adjustment of the rack member 82 on the rod 80. A nut 92 retains the pinion 86 in any posit-ion to which 1t may be moved.

The outer surface of the heel seat portion of an insole after it has been fitted to a last is more or less convex in. planes transverse to the contour line of the heel seat.v

Consequently, the marginy of the up-per where it is folded over the insole in the lasting operation is inclined downwardly toward the edge of the insole when the lasted shoe is disposed ininverted position, as clearly appears from Fig. 8 in which the upper is designated A and the insole B. Itis desirable lthat the heel sie-at portion CI of the outsole shall be shaped to correspond with the configuration of the upper and in# sole. Accordingly, I have provided thethroats 28, 32, `and 34 with plates 94, 96 and 98 respectively having' their lowerl sur; faces 100 inclined downwardly and outwardly from their nail receiving passages to f, incassa Vso a degree corresponding substantially with the inclination of the upper and insole. The surfaces of the plates 94, 96, and 98 engage the tread surface of the heel seat end of the sole adjacent toits marginal edge and press it into close contact with the folded over margin of the upper. lt is recognized that the plates 94, 96, and 98 upon which the heel seat molding surfaces are formed may be constructed integrally with the throats 28, 32, and 34 respectively, or means separate from the throats may be provided for shaping the heel seat without departing from the principle of the invention.

The nail receiving and controlling parts of the throats 28, 32 and 34 may be, and as shown', are constructed as fully illustrat-ed and described in the copending apiplication, above referred to.v inasmuch as the organization of such parts of the throats constitutes per se no part of the presentl invention, .a further description thereof is deemed unnecessary. The throats may be secured to their respective castings in any suitable manner. As shown in Figs. 4 and 6, the throats 28 and 34 are fiXed to the cast ings 40 and 52 by screws 102, 104 respective-- ly, and the throat 32 is formed with an upstanding projection 106 which is dove-tailed into the front face of the casting 76 and retained in position by a set screw 108 and a plate 110 secured by screws 112.

rl`he means for supplying nails to the nail receiving passages of the throats 28, 32 and 34 and for driving the nails is also more fully set forth in the copending application above referred to. vSuch means comprises iieXible tubes 114 (see Fig. 1) adapted to receive nails from the several raceways 10. The tubes 114 communicate with openings 116 in ears 118 on the castings 40, 52, and 76 respectively. Each of said castings has pivoted thereto below the ear 118 a conductor 120 having openings122 registering with the openings 116 in the ear 118 and normally positioned by springs 123 so as to deliver nails into the passages in the throat. The nails are forced into the work by drivers 124 carried by driver bars 126 arranged to be simultaneously actuated by a member 128 slidably mounted on posts 129 and limited in its downward movement by bu'ers 130. 'lihe member 128 is carried by a lever 131 fulcrumed in the head 4 of the machine and elevated by a cam 132 onthe shaft 15 through the agency of an arm 134. rIhe lever 131 is impelled downwardly to cause the drivers 124 to pro--V ject ,the nails into the work by springs 136. The driver `bars' 126 have angular faces 138 which swing the conductors out of the way of the drivers 124 iny their nail driving movements. j

Means is provided for presenting work to the nail inserting mechanisms in a manner to facilitate operation on the work. 'lihis means preferably comprises a clamping band which is made substantially U- shaped to accord with the configuration of the counter or heel end of a shoe on which it is designed to act. rlhe clamping band 140 is composed of leather or other suitable flexible material. In order to afford support for the band at its rear end or, in other words, at the bight of the band, a clip 142 (see Figs. 1 and 6) is riveted to the band at such point. The clip' 142 is in turn carried by a stud shaft or post 144 loosely mounted in a carrier 146 slidable in a guideway on the head 4. Downward movement of the post 144 is limited by an enlarged part 145. ln order to permit the clamping band 140 to be appropriately positioned for operation on shoes of varying sizes, the carrier 146 is adjustably secured to the head 4. A convenfent means for effecting such adjustment comprises teeth 148 on the under side of the carrier meshing with a pinion 150 (see Fig. l). The shaft of the Apinion 150 may be provided with a handle to facilitate its rotation and may be retained in angularly adjusted position in Various ways as will be obvious to those skilled in the art. Suitable means involving a pawl carried by the shaft and a ratchet mounted on the head 4 is shown in the copending application heretofore referred to.

The legs or sides of the clamping band 140 are supported by clips 152 carried by posts 154 and 156 mounted in arms 158 and respectively. Each of the clips 152 is formed with upwardly extending flanges 164 (see Figs. 2 and 4) between which the lower edge of the band 140 is received. The legs of the band are constrained against transverse movement relatively to the flanges 164 but may have endwise movement with relation to said clips for a purpose which will hereinafter appear. rlhe posts 1.54 and 156 have blocks 166 pivoted thereon for movement in horizontal planes and platesrl68 are fulcrumed to the blocks 166 at 167 for movement in vertical planes. 'llhe pressure plates 168 have concave surfaces disposed for engagement with the outer surface of the band 140 to press it against the work, and the double pivotal movement of the plates enables them to contact closely with the band regardless of changes in the configuration of the band resulting from the presentation of work of different dimensions to the machine. rlhe arms 158and 160 are fulcrumed on the head 4 at 170 and 172 respectively and, as shown, are operated by links 171 and 174 from bell crank levers 176 and .178 pivoted at 180 and 182 to the head 4. Each of the bell crank levers 176 and 178 is formed with a toothed segmental portion, the segments being arranged to llt mesh with rack bars 184.` and 186 slidably bars 184 and 186 respectively and carried by a head 190 on a rod 192 sleeved into a housing 194. A spring 195 interposed between the front' wall of the housing 194 and a nut, or the like, on the rod 192 transmits movement from the housing yieldingly to the rod and thus to the arms 158 and 160 in a direction to press the clamping band 140y against the work. The lhousing 194 is toothed on its upper side for'meshing engagement with a pinion 196. The shaft 197 (see Fig. 2) of the pinion 196 carries a larger pinion 198 co-acting with the toothed end of a bell crank lever 200 fulcrumed at 202 on the head 4 and having a roll 206 riding on a cam track 207 on the cam wheel 204.

In order that the degree of pressure on the legs of the clampin band 140 may be conveniently changed, ig desired, or maintained uniform during operation on work oit'- different dimensions, each of theY links 171 and 174 comprises a rod 208 having its head pivotally connected to thel arm 158 or 160 and its shank received in a sleeve 210 clamped on the rod between its head and aV nut 212. The sleeve 210 is threaded on, itsouter surface for engagement with internal threads on the split thimble 214 having a rounded boss'216 on its closed end seated in an opening 218 in the arm 176 or 178. A rod 220 passing through the boss 216 secures the thimble 214 to the arm. With this construction, rotation f the sleeve 210 will lengthen or shorten the link 171 or 174, thus 'increasing or decreasing the pressure of the.

clamping band 140 on the work. The head 222 ofthe sleeve 210 is preferably knurled to facilitate the rotation of the sleeve.

'To the end that the pressure plates 168 may be caused to act on rthe clamping band 140 Lwhen jo erating on shoes of certain dimensions, or example, relatively large shoes, at points more nearly adjacent to the struction (see Figs. 2 and 6), the plates 224 and 226 are channeled at 228, and the bottbms of the channels are formed with slots 230 through which pass bolts 232 havlng their heads received in the channels 228.

The back' or bight of the band is maintained firmly against rearward movement by a brace 234 having its forward 'surface concave to conform with the outer surface of the band. As shown; the brace 234 is formed integrall with ayoke 236 loosely mounted on the en rarged portion 145 of the stud shaft 144.v The yoke 236 is constrained .244 and 246 pivoted thereto for movement in a horizontal plane. The plates 244 and 246 are yieldinglyforced against the band 140 by spring-pressed plungers 248 and 250 seated in bosses on the 'ends of the yoke 236. The plates 244 and 246 engage the corners of the clamping band 140 and force such portions of the band into firm contact with the work. The provisions hereinbefore described for endwise movement of the legs of the clamping band 140 between the anges 164 of the clips 152 permit the corners of the band to be pressed closely against the work regardless of variations in the shape or size of the work.

It will be clear from the foregoing that the nail inserting mechanisms or umts 22,

24, and 26 may be moved relativel to each other and to the work to accommo ate them rear nail inserting unit 22, in the present exemplification of the invention is designed to be adjusted manually. I prefer, however, forr the sake of convenience of o eration and flexibility-of adjustment that t e operative positions of the nail inserting units 24 and 26 be determined by the work itself. As shown, the clamping band 140 and its o erating means are utllized to this end. f he posts 154 and `156 are extended upwardl for engagement with the downturned en s of metal strips 252 secured to the plates 56 of the end units 26, andsthe plates 78 of the corner units 24 carry strips 254 whose down`v turned ends contact withthe outer surface ofthe clamping band. Consereiently, as the arms 158 and \160 yare mov toward. the work, the end units` 26 are forced inwardly against the resistance of the springs 66 l and the corner units 24 move inwardl with the band 140 under the impulse .of t e springs 84. The adjustable connectiony 60, 62 -between the end units 26 and the plates 56 .enj Los the outsole to be accurately conformed to 4 the edge of the upper and insole, theshoe is presented to the clamping band with the surface of the outsole spaced from the upper surface of the band. It is desirable,-

however, that the shoe be clamped as close to the outsole as possible and still permit the'edge of the heel seat to be pressed down to the required degree. Means is accordingly provided for positioning the work with relation to the clamping band. lin the illustrated construction, suc means comprises a member 256 disposed for engagement with the surface of the heel seat wit in the space defined by the nail inserting u its 22, 24 and 26. 'lihe work positioning member 256 is mounted for vertical sliding movement on the head 4 and, as shown, is provided with teeth 258 meshing with a pinion 260. The pinion- 260 is operated by a rod 262 which derives its 'movement from a cam roll 263 (see Fig. 7) registering with the track 264 of the cam 204. Suitable operating connect-ions between the work positioning member 256 and the cam 204 are descried in the copending application above cite 'llhe work is supported on a jack 266 which may be constructed and operated substantially as shown and described in the aforementioned application. The jack 266 is moved in a direction to carryltlie work into the grip of the clamping band 140 by a rack bar 268 meshing with a pinion on a shaft 270 journaled in the column 2 of the machine. rlhe shaft 270 carries a ratchet wheel 2172 operated by a ratchet (not shown) on an arm 274 which is in turn connected to a link 275 pivoted to the head 206 of a rod mounted loosely in the end of a lever 278. The lever 278 is fulcrumed on the head 4 of the machine at 280 and carries al roll 282 registering with a track 284 on the cam wheel 204. The rod having the head 276 is enclosed on the side of the lever 278 opposite from said head by a sleeve 286, between which and an enlarged portion of the rod is interposed a spring by which movement of the lever to the right chine frame.

(Fig. 1) is transmitted yieldingly tothe shaft 270 and the jack 266. 'llhe shaft 270 also carries a ratchet 288 to which movement is transmitted by a pawl 290 operated by a link 292 connected to one arm oit a bell crank 294 fulcrumed on the column 2 on the machine and having its other arm in the form of a toothed segment meshing with yteeth on the under side of the housing 194.

A second 'link 296 extends from the bell crank lever 294 to an arm 298 on the shaft 300 journ-aled in' the column 2 of the ma- A pawl carried by the arm 298 and acting on a ratchet on the shaft serves to impart upward movement to the jack 266 in a manner which will be obvious to those skilled in the art. The link 296 is preferably made in two sections having a spring interposed between them, as shown in the aforementioned application, to theend that the movement of the bell crank lever Lacasse 294 will be yieldingly communicated to the jack 266.

The clutch mechanism is arranged to bring the machine to rest with the arms 158 and 160 separated to the maximum extent to open the clamping band 140. rllhe jack 266 occupies at the same time its fully lowered position and is tipped forwardly to facilitate the presentation of work to the jack. rli`he work positioning member` 256 is at the limit of its downward movement. To operate the machine, the operator places the work on the jack^266 and by means of a treadle (not shown) raises the jack to bring the heel seat into engagement with the positioning member 2,56 which, as before stated, locates the work with the edge of the heel seat spaced by the proper distance from the upper edge face of the heel band. .He then depresses a treadle to start the machine. lVlien power is applied to the machine the cam 204 is rotated in the direction of the arrow on Fig. 7. As. the cam rotates the roll 282 on the-lever 278 rides on a raised portion of the cam track 284, thereby moving the jack 266 back yieldingly to thrust the work into the band 140. As the cam continues to rotate, a raised portion of the cam track 207 acts on the roll 206 of the bell crank lever 200 to move the arms 158 and 160 inwardly to press the clamping band 140 against the work and simultaneously to actuate the lbell crank lever 294. When the bell crank lever 294 is actuated, it moves the jack 266 positively to thrust the work further into the grip of the band 140 and exerts an upward pull on the link 296 thus tending to move the jack upwardly. By reason, however, of the upper surface yof the heel seat being in engagement with the work positioning member 256, the jack 266 is moved upwardly at this time only to the extent to which the work yields, the main movement of the link 296 being taken up by the spring connections in said link and serving to apply pressure on the work.' lin the continued operation of the machine, the roll 263 which controls the work positioning member 256, moves onto a depressed part ot the cam track 264, thus permitting the positioning member 256 to be lifted. At the same time, a further rise on the cam track 207 engages the cam roll 206 on the bell crank lever 200 to cause the jack 266 tobe raised with the positioning 'member' 256 without lessening the spring pressure on the work. The work positioning member 256, the jack 266, and the work move upwardly together until the work contacts with the under surfaces of the throats 28, 32, and 34,' -after which, the continued movement of the member 256 elevates said member above the surface of the heel sea-t. The inward movement of the arms 158 and 160 is transmitted to the end lill@ nail inserting units 26, by the strips 252 and posts 154 and 156, and the upward pressure of thev work against the inclined surfaces 100 of the throats ,causes the contour edge of the heel seat end of the outsole to be pressed down-firmly on the upper and insole. As clearly appears from Figs. 1, 4, and 6 the clips 142 and 152 are connected to thel posts 144, 154, and 156 at points normally spaced from the'lower surfaces of the carrier 146 and the arms 158 and 160. Consequently, as the work moves upwardly, the clamping band 140 partakes of such movement. While the above-described op-l erations are being eifected,` the nail supplying mechanism is operated to'deliver nails to the nail receiving passa es of the throats, and after the work has een pressed upwardly against the throats, the d'river cam arrives at a point in the cycle of its movement which permits. the drivers to be forced down to drive the nails into the work. The further rotation ofthe cam shaft releases the grip of the clamping band 140 on the work and lowers the jack, at the same time moving it outwardly from the machine to u facilitate the removal of the iinished work and the substitution of other work therefor. The work positioning member 256 is also lowered to a position properly to locate the fresh piece of work relativel to the clamping b-and, after which the mac ine again comes to rest.
