To all whom it may concern:

Be it known that we, FRED L. Arms and Flinn L. MACKENZIE, citizens of the United States, residing at Everett, in the county of Middleseir and State of Massachusetts, and Beverly, in the county of Essex and State of li lassachusetts, respectively, have invented certain Improvements in Mechanism for Use in Attaching Shank-Pieces to Shoes, of which the following description, in connection with the accompanying drawings, isja specification, like reference characters on the drawings indicating like parts in the several figures. i

This invention relates to mechanism for use in operating on shoes to which shank pieces are attached and is particularly designed for application to a fastening inserting machine adapted to tack the shank pieces to the shoes. y

in the manufacture of certain kinds of shoes, it is customary to attach to the shank portion of the insole of a shoe, prior to the laying on of the outsole, a shank piece calculated to strengthen the shank of the shoe and to improve the appearance of the shoe.

The shank piece is commonly reinforced by a metal strip applied to the under side of the shank piece and extending lengthwise of the shank piece along substantially its median line and, in the finer grades of shoes, is molded from rubber or composition and is relatively stiff and inflexible so as to retain its shape under the pressure exerted by the outsole laying machine. The shank piece facilitates the production of the desired ex terior contour and appearance of the tread surface of the hoe by reason of the molding of the outsole by the sole laying machine over the convexly curved outer surface of the shank piece. To the end that the shoe may be durably constructed and symmetrically formed, it is essential that the plane surface of the shank piece at the forward end of the shank piece be accurately alined with the surface of the insole forwardly of the shank piece as otherwise a space will be left in the finished shoe either between the outsole and a the surface of the shank piece or between the outsole and the insole adjacent to the shank piece, depending upon whether the plane surface of the shank piece is disposed inwardly or outwardly of the plane of the surface of the insole". In either case,=it wiil be seen that the outsole will not present the smooth and even appearance which is very desirable in high grade shoes and that the wearing qualities of the shoe will be impaired by reason of the outsole not being properlysustained at all points.

In the manufacture of shoes in which shank pieces'of the kind above described are used, the outsole is molded to substantially the shape which it will have in the finished shoe previous to its application to the shoe, there being formed in the outsole in the molding operation, a well-defined angle marking the break line between the shank portion and the forepart of the outsole. Before the outsole is laid on the shoe, the surface of the insole and shank piece and the inner surface of the outsole are coated with cement which retains the outsole in position until the permanent attachment of the outsole to the shoe When the outsole is applied to the shoe the break line of the outs'ole should coincide with the line of intact ing of the outer surface of the body of the shank piece with the plane surface at the forward end of the shank piece hereinafter for convenience of description termed the break line of the shank piece, but by reason of the break line of the shank piece being concealed by the outsole as it is laid on the shoe and inasmuch as the cement prevents movement of the outsole relatively to the insole and shank piece after it is placed thereon, it is difficult for the operator to locate the outsole exactly. with the result thata large proportion of the outsoles are not properly positioned. It is apparent that if the outsole is not applied to the insole and attached shank piece in such manner that the break line of the outsole coincide with the break line of the shank piece, the pressure exerted by the sole laying machine on the outsole will form a crease in the outsole at the point where it lies over the break line of the shank piece greatly injuring the appearance of the shoe.

In the present shop practice, the operator applies the shank piece to the shank portion of the insole and presents the work to the throat piece of a tacking machine, inserting a tack through the rear portion of the shank piece and into the insole at one side of the metal strip of the shank piece and then shifts the shoe relatively to the throat piece and inserts a tack through the shank piece at the other side of the metal strip. In doing this work, the operator relies upon his eyes to determine the proper position of the shank piece with the result that the shank pieces are very frequently attached to the shoes in such wise that the surface of the shank piece projects too far outwardly or lies too far inwardly from the surface of the insole with consequent lack of support to a portion of the outsole when it is applied to the insole. The irregular location of the shank pieces adds to the difficulty of properly matching the break line of the outsole with the break line of the shank piece. Moreover, if the shank piece has not been properly applied to' the insole, the matching of the outsole with the shank piece so that the break line of the'outsole coincides with the break line of the shank piece causes the outsole to be improperly located relatively to the body of the shoe.

An object of this invention is to provide means whereby the defects arising from present methods of applying the shank pieces may be obviated and the shank pieces invariably positioned on the shoe with the surfaces of the shank pieces appropriately related to the surface of the insole and with the shank pieces uniformly located on the shoe so as to facilitate the application of the outsole.

To this end, an important feature of the invention consists in the combination with mechanism for operating on a shoe having a shank piece loosely superposed thereon, of

:: means mounted on the frame which carries said me hanism for positioning the shank piece relatively to said mechanism. Preferably, and as shown, the member which engages the shank piece is formed with surfaces angularly related to each other in such a manner as to engage the shank piece at each side of the break line of the shank piece.-

t has been determined by experiment that as regards shoes of the same size and like styles, the distance from the back of the shoe to the break' line of the insole is substantially constant. It results, therefore, that, if shoes of like size and like styles'are presented to the fastening inserting machine with the backs of the shoes lo"ated at a certain predetermined distance from the shank piece positioning means, the shank plece, the location of which is determined 1 by the shank piece positioning means, will invariably be accurately placed on the shoe. Accordingly, another feature of the invention resides in the'combination with means for positioning a shank piece loosely superposed on a shoe, of means for positioning a shoe so that the shank piece will be propfirly located on the shoe,

In order that the invention may be con- Veniently employed in the manufacture of shoes of different sizes and styles the shoe positioning means, in accordance with a still further feature of my invention, is made readily adjustable relatively to the shank piece positioning means, and means are pro vided for indicating the proper position of the shoe positioning means for operation upon a shoe of any size and style.

. The invention also contemplates the arranging of the shoe positioning member in such manner as to enable the operator to present the shoe in proper position with relation to the shank piece positioning means and the fastening inserting mechanism with the greatest possible ease and quickness. Accordingly, the shoe positioning member is mounted for movement in a vertical plane and is normally positioned below the plane of the fastening inserting mechanism in full View of the operator and in such location that the operator can engage the shoe therewith without obstruction. After engagement of the shoe with the shoe positioning member, said member is moved upwardly by the shoe in the presentation of the work to the fastening inserting mechanism. Preferably and as shown, for the purpose of ex- Jediting the presentation of the work to the astening inserting mechanism, means is provided for maintaining the shoe engaging surface of the shoe positioning means in substantially the same horizontal plane in different adjusted positions of the shoe pcsitioning means.

The invention also contemplates the mounting of devices on the frame of the fastening inserting machine constructed and arranged to position the shank piece at its rear end and to support the shank piece independently of the shoe in a position determined by the shank piece positioning means. I

It is recognized that the invention-is not limited to the particular embodiment thereof herein described and illustrated or to operation on shank pieces of the special form described; for example, certain features of the invention are applicable to the attachment of relatively light shank pieces such as are used in the cheaper grades of shoes and which do not have a. defined break line. It is intended therefore that the scope of the invention shall be limited only by the language of the appended claims.

Other objects and features of the inven tion will appear as the description proceeds.

The invention. will be described, by way of example, as applied to a fastening inserting machine of the type disclosed in United. tjtates Letters Patent No. 1,106,393, granted August 11, 191 on an application of Fred lli. Mackenzie, and reference may be made to said Letters Patent for a complete description of parts not fully described herein. The machine comprises a nozzle or throat-piece 2 through which fastening-S pass for insertion into the work, the fasten'. being; forced. into the work by a driver 4i which reciprocatcd upwardly and down Wardly in suitabie guides in the machine frame 6. The illustrated machine is of the class which inserts previously formed fastenings of relatively small size hereinafter sometimes denominatec tacks, and the operation of the machine is controlled by treadle, not shown, which is operatively connected by a rod 8 to a starting and stopping mechanism denoted by the reference numeral 10, Fig. 1.. The above described parts constitute in themselves no part of the present invention and are fuliy set forth in the Letters Patent above referred to, for which reason a fuller description thereof is deemed unnecessary. Although the invention is described in its application to a machine for attaching; shank pieces to shoes by metallic fastenings, it is to be understood that the invention in its broader aspects is not limited to any particular form. of shank piece attaching means.

lin the use of the machine a shank piece 19. is secured to the insole of a shoe it by means of tacks 16 and 18, his. t, driven through the shank piece nearits rear end and at either side of the metal strip 20 which serves to reinforce the shank piece.

As above stated, it is desirable that the shank pieces be properly and uniformly positioned relativelyto the soles of the shoes and to the point of insertionof the fastenings. To this end, I have mounted on the frame 6 of the fastening inserting machine a shank positioning member 22 adjustably secured to the frame of the machine by bolts 24 passing, through slots 26 in the up per end of the shank positioning member. .r-tdgustably secured to the shank pOSl'tlOlllDg F member ,dtat ts lower end, means of a bolt or the like28, is a gage member 30 which is formed with shank engaging surfaces 32 and 341- angularly related to each other, the shank engaging surface 852 being arranged to engage the plane surface 36 at the end of the shank piece forwardly the break line to of the shank piece and the shank engap} ing surface 3d being designed for engagement with. the curved upper su face 88 of the body of the shank piece 12 adjacent to and rearwardiy of the break line 40 of the shank piece. When a shoe with a shank piecesupergoscd thereon is presented in operative relation to the throat piece of the fastening inserting machine, the shank engaging surfaces of the shank positioning; member 22 will engage the shank piece and position the same relatively to the insole of the shoe and the throat 9. of the fastening inserting mechanism.

As hereinabove stated, it has been found by experiment that shoes of the same size and of the same or like styics do not differ appreciably in their dimensions from the backs of the shoes to the break line between the shank and forepars of the insole. lit foilows, therefore, that if means are provided for positionin the backs of the shoes always in the same relation to the shank positioning means when OPGIEttT'lQ; on shoes of like size, the shank pieces will be located on the shoes with great accuracy and uniformity. lin the illustrated embodiment of the invention, the shoe positioning means comprises a work engaging member 4:2 carried by the frame 6 of the machine. Since the distance between the back of the shoe and the breals: line between. the shank and the forcpart varies in shoes of different sizes, means are provided for adjusting the work engaging member 4.9. for different sizes of shoes, and means are also provided for indicating the proper position of adjustment of the work engaging membe for shoes of any size. ids-id means comprises bracket at in which is journaled a rock shaft 46 carrying an arm d8 upon which the work engaging member is fuicinmcd, as indi cated at 50, it will be ciear from the foregoing); that if the shaft as is rocked or oscillated in either direction, the position of the wor; eiipgag" surfaces of the work onmember rciatiyr-ily to throat piece 2 of the fasteninn i sorting mechanism and the shank positioning means will be changed. Means provided for footing; oscillating movement of the rock shaft 46 in the form of an arm 52 fixedly mounted on the end of the rock shaft 41:6 and extending upwardly therefrom to a point adjacent to the indicator scale 54, which is toothed or serrated at 56 for engagement therewith of a spring; pressed trigger 58 carried by the arm 52, the serrations 56 and trigger as operating; to maintain the arm 52 and perforce the rock shaft 46 and work engaging member 42 in any position of adjustment to which they may be moved. As plainly appears from Fig. 2 of the drawings, the indicator scale 54 marks the proper positions of adjustment of the work engaging member 42 for the dlfferent sizes of shoes. 7

It is important that in all positions of adjustment of the work engaging member 42 relatively to the throat piece 2, the work engaging surfaces should lie normally in substantially the same horizontal plane, to the end that the operator may not be inconvenienced by the necessity of observing the position of the member 42 each time work is presented to the machine but may present the work in operative relation to the work engaging member without conscious inspection of said member which he can do by familiarizing himself with the location of the work engaging member, if the normal work receiving position of the member is not materially changed when adjustments are made. In the present instance of the invention, this is effected by the provision of a spring 60, Fig. 1, which operates against the pin 62 carried by the work engaging member 42 in a dlrection to urge the work engaging end of the member downwardly, and a cam member 64 extending rearwardly from the bracket 44 in position to be engaged by the pin 62 to limit the downward movement of the work engaging member 42. By reference to Fig. 1, it will be seen that by reason of'the pivot 50 of the work engaging member 42, being arranged substantially in the vertical plane of the rock shaft 46, a movement of the arm 52 in either direction from the position illustrated in said figure will tend to move the work engaging member 42 upwardly. It will be further noted, however, that in the positioin of the parts indicated in Fig. 1 the pin 62 is substantially in line withthe lowest point of the cam' 64. Since the curvature of the cam member 64 from its lowest point in either direction is greater than the curvature of the path of movement of the pivot 50 about the rock shaft 46, when thework engaging member I 42 is moved in either direction from the position shown in Fig. 1, the tendency'of the work engaging end of said member to be raised by the bodily movement of said mem ber is countervailed by angular 'movement of said member 42 on its pivot 50 due to the pin 62 having imparted thereto an upward movement of greater extent than that of the 1)1V0t 50.

The bracket 44 is carried by a member 66 shdably mounted in ways 68 extended from the machine frame 6. Means are preferably provlded for adjusting the slide 66and the parts carried thereby in the ways 68 and, as

illustrated, such means comprises rack teeth to the throat-piece of toning may be inserted 70 formed on the slide (36 and engaged with the teeth of a pinion stud 72 journalcd in ways 68. The slide G6 may be locked in any position of adjustment in the ways 68 by the bolt 74, Fig. 1.

It has been found in practice that the distance between the back of a shoe and the break line between the shank and the forepart of the insole although the same in shoes of like sizes and of like styles. may differ in shoes of different styles though of the same size. t follows, therefore, that if the parts are so related that the indicator 54 which may be called the size indicator properly signifies the position of the work engaging member when operating on shoes of a certain style, such size indicator might not mark the proper position of adjustment of said member for shoes of different style.

By movement of the work engaging mem ber 42, the bracket 44, and the size indicator 54 together in the appr priate direction relatively to the shank positioning means 22 to an extent equal to the amount by which the distance between the back ofthe shoe and the break line in shoes of the style to be operated upon differs from the distance between the corresponding parts of a shoe of like size of the style for which the parts are set, the size indicator may be made to denote correctly the positions of adjustment of the work engaging member for shoes of the style to be operated upon. Such move ment is effected by sliding the bracket 44 in the ways 68, and in order that adjustments for changes in styles may be accurately made the pinion stud 72 carries a finger 76 associated with an indicator 78 which may be termed the style indicator.

In the use of the mechanism hcreinbcfore described, a shank piece which may be of the form shown in Figs. 4. 5 and G is applied to the shank portion of the insole of a shoe as portrayed in Fi 4, and the shoe with the shank piece superposed thereon is presented the fastening inserting machine in position such that a fastening may be inserted through the rear end of the shank piece at one side of the metal strip of the shank piece as indicated at 16, Fig. 4. The shoe and the shank piece are then moved together laterally and again presented to the throat-piece of the fastening inserting machine in a position such that a second iii-is as indicated at 18, the shank piece ataccording to the usual factory practice, placed on a rack or other device whereby the shoe may be transported to the machine for laying the outsolcs thereon.

The shank piece may be presented in proper relation to the throat piece of the fastening inserting machine previous to and independently of the presentation of the 4. The shoe with tached thereto is then retreat and 6) and are constructed to yield upon the insertion of the metal strip of theshank piece between them and to engage the strip frictionally in a manner such as to permit 522 being omitted. It is preferred, however,

ready lateral movement of the shank piece from one tack inserting position to the other but strongly enough to sustain the shank piece adjacent to or in contact with the throat piece of the fastening inserting machine and in engagement also with the shank piece positioning means 22. It will be understood that the shank piece supporting device S t also operates as a gage to position the shank piece at its rear end and that said device might be relied upon, if desired, as the sole positioning means for. the shank piece, the shank piece positioning member to utilize the member 22 to position the shank piece longitudinally of the shoe and to depend upon the device 84 to support the shank piece and to position the rear end of the shank piece laterally. The shank piece having been placed in position, the shoe is presented to the fastening inserting machine,

being accurately positioned by thework engaging member 4-2. In the operation of the outsole molding machine the sole is positioned relatlvely to the device which molds the sole and forms the break line in the sole called the size indicator." When it is intended to mold soles for shoes of acertain size the gage is moved until the pointer of the indicator which-is connected with the gageregisters with the corresponding member on the indicator scale. l romthe foregoing, it will be clear thatsolesintended for shoes of the same size will be of uniform dimensions from the heel seat end of the sole to the break line. Adjustments for various sizes are made by moving the gage toward and from the mold thus commensurately decreasing or increasing-the distance between the heel seat endof the sole and the break Shoes of like size but of unlike styles line. sometimes require soles of. difi'erent lengths. A second indicator Wl'llClT may be denomn hated the style indicator is therefore provided to'markthe extent of adjustment of the gage member and the size indicator necessary to cause the latter to indicate accurately the positionwof the gage appropriate to a sole designed for a shoe of a different style from that for which the molding machine has previously been set.

It will be clear from the above that adjustments of applicants positioning member 42 may be made in accordance with the adjustments of the outsole molding machine, applicants size indicator and style indicator being set correspondingly to the size indicator and style indicator of the molding machine. Thedistance between the back of the shoe and the break line of the shank piece may thereby be made to bear a determined constant relation t the distance be tween the rear end of the outsole and the break line ofthe outsole. The outsoles are made of a length to extend somewhat beyond the backs of the shoes when applied thereto, and since, by the use of the mechanism hereinbefore described inasmuch as the shank pieces are uniformly located the amount of such projection is made constant when the outsole is properly applied to the shoewith the break line ofthe outsole coinciding with the break line of the shank piece, the operator is enabled to locate'the outsoleon theshoe accurately and conveniently by holding the outsole right side up in one hand and with the other holding the shoein upright position and applying it to the outsole with the back of the shoe spaced by the known distance from the end of the outsole. This method of operation possesses very marked advantage over present methods, which involve much more manipulation of the work and in which one of the elements, a. a, the break line of the shank piece, which are relied upon to locate the outsole is rendered invisible in the operation of laying on the outsole. The tendency in laying on outsoles according to the present method is for the operator to feel with the outsole for the break line of the shank piece inorder to determine the correct position of theoutsole. The cement applied to the parts prevents, however, movement of the outsole on theshoe and thus precludes the positioning of the shank piece in the above manner.
