This invention relates to machines for use in themanufacture of shoes forshaping uppers over lasts, and is 'herein illustrated in its application to a "pulling-over machine constructed especially 5 for use in pulling over the uppers of stitchdown shoes. It is to be understood, however, that in some of its novel aspects the invention-is not limited' to pulling-over machines nor to machines for operating on shoes of that particular kind.

Pulling-over machines of the well-known type exemplified by the disclosure of United States Letters Patent No. 1,029,387, granted on June 11; 1912,:upon an application of R. F. McFeely have been -modified heretofore with the object of adapting them betteror use to pull over the uppers-of stitchdown shoes, as illustratedin LetterslPatent'No. 1,916,275, granted on July 4, 1933 upon "an application of James 1M. Matheu. As disclosed in the last-mentioned Letters Patent, after :the pulling-over grippers have been operated to pull the upper heig htwise of the last, the upper is fastenedby'tacks'driven infdirections inclined relatively to the bottom =face of the last in locations substantially at thejunction of the bottom face and the upper-shaping surface of the last,so that the marginal portion of the upper may :be readily turned butward and a sole or insole applied over the outt'urned margin while some or all of thetack-s-arestill inthe last. The upper fasteningdevicesare movable inwardly toward theshoe into upper-fastening positions and carry means for clamping the upper before the fastenings are driven, 'such 'devices also acting in their inward movements to release the grippers from the upper through contact with releasing members on the grippers.

One object of the present invention is to'affordincreasedinsurance that in a machine op-i erating as above described the upper will be clamped and held securely in the proper relation tothe'last'inthe interval between its release bythe grippers and the 'driving of the fastenings. For purposes of the invention the construction here-' in shown islaccordingly such that the'grippers in their upper-pulling movements "heightwise of I the last receive also :movements in directions to draw the :upper inwardlybver the edge of the last bottom. serves not only to position the marginal portion of the upper close t0 that :por-' tion of the last-against which it is to be clamped by the clamping -means, but also to carry the gripper releasing members farther'away from the upper-fastening devices, so that I better insurance is afiorded a &inst' 1. .ase;0f thesrippers from. the upper by the inward movements of these devices before the clamping members arrive in clamping. positions. fThe ,above described inward 1 movements ,dfth'e' grippers .,are efie'cte d by overdraw springs w'itli which machines of. the illustrated type arercustomarily provided, and torch; 5

der'these springs effective to impart such .moy emerits,tdtheggrippersinthecourse.of the up er pulling enemies; there are proiiidedon the gripper bars inclined ,f acescooper'ating with embe s at the inner .sides .of the grippers to ,COMIQI the latter inv opposition ,to. the overdraw springs, these faces extending insuch inclined relation, to the directions of the .upp'erepulling movementsof (the grippersj heightwise of the .last :as to Sperrnit the grippers to be m0yedinwardlybylthesprings; as they receive their upper-pulling movements, through distances that ,are proportional to Tthe extent of such,pullingmovements.

The driving of the tacks precisely {the de, sired locations at the junction of the bottomiace and ,the upper-shaping surface of the lastrequires .flthat the last .beaccurately positioned height wise relatively to" the upper fas'tening devices. Qln machines ,of the [illustrated type the heightyvise position .of the ,lastgis determined by a workl rest positioned opposite thebottom-fae of the last .and comprising membersarranged respectively. at the end and the sidesof the ;:forepartpithe last bottom. ,Since the bottomsmf the ,ioreparts .of .1a'sts.are.,frequently cunved more 01" less laterally as' well .as lengthwise, theicon structio'n herein. shown is such -,that the members of the Iwork rest ;are' arrangecl to engage the :bottom face .of. the last .in' locations as closeias is practicable ,to the points where fastenings are driven. As j-illustrated, the side ,members of the work ,rest [are thus .arranged to engage theYlast' in locations opposite the points where the ,rearmost side tacks are driven vand iat le ss distances from ,fthe edge of the last bottom vthan the width of jtheQmarginaI [portion .of the upper extending beyondsaid edge, and ,theQend member. is .ar ranged to engage the last in a location directly opposite-theypoint where the. .end tack is driven" V and in similarly close relation to the Ledge ,ofthe 45 last bottom For greater accuracy withrespect' to the locations of the tacks 'injoperagting on lasts of different styles and of differentsizesgprovision is also afforded 'by this invention fo'rj-various adjustments of the -work rest memberspes- 50 pecially- -of the side members",'=the latter in the construction shown being ad justable heightwi's'e of .the-ilast relatively xtoxtheend' member and also adjustablerawidthwise of the" last relatively to each other. In the construction of the work rest; and especially in the provision for different adjustments of its side members, novel features are to be recognized which are not limited to use on stitchdown shoes where the work rest engages the bottom face of the last, but are applicable also to work rests engaging a sole or insole on the last.

The above and other novel features of the invention, including various novel details of construction and combinations of parts, will now be more particularly described by reference to the accompanying drawings and pointed out in the claims. f v y In the drawings,

Fig. 1 is a View from the front, partly in sec-' ing and fastening the upper at the opposite sides of the forepart, the parts being shown in the positions that they occupy at the time of the upperfastening operation; 7 v V I Fig.2 is a view in side elevation of the upperpulling and fastening means atthe end of the toe; together with portions of the work-positioning means;

Fig. 3 is a Fig. 4 is a'view similar to Fig. .1 of portions of the structure there shown, but with the parts in thepositions that they occupy at the beginning of the upper-pulling operation;

Fig. 5 is a view similar to Fig. 4 with the parts in the positions that they occupy after the upperpulling operation and prior to the movement of the upper-fastening means into position for the driving of the fastenings; and

Fig. 6 is a view 'inthe direction of the arrow A in Fig. 2, illustrating more clearly the relation between the last and shoe and certain portions of the structure at the time when the fastenings section on the line III-III of are driven.

' As is well known, a machine of the type in which the invention is herein shown as embodied includes in its organization a gripper 10 (Fig. 2) for pulling the upper atthe end. of the toe and grippers 12 for pulling it at'the opposite sides the grippers that'may be necessary to adjust the upper properly on'the last. When the machine is'again started, side clamp arms 16 are swung inwardly toward the sides of the shoe to clamp the forepart of the upper against the last and support the last'for the upper-fastening operation. In the continued operation of the machine upper-fastening devices are moved inwardly into positions to drive upper-holding fastenings, these devices carrying additional means for clamping the upper to assist inholding it until the fastenings are driven. Release of the grippers from the upper is effected by engagement of the inwardly moving upper-fastening devices with members 18 at the outer sides of the grippers,

whereupon thegrippers are moved farther upwardly and are also swung inwardly to make way-for the upper-fastening devices. After the fastenings have been driven the parts of the machine are returned to their starting positions and the shoe is released.

In general similarity to the construction shown in the above-mentioned Letters Patent No. 1,916,- 275, the upper-fastening devices in themachine herein shown are so constructed and arranged as to drive a single tack at the end of the toe and two tacks at each side of the forepart, the tacks being driven in locations substantially" at the junction of the bottom face and the upper-shaping surface of the last, i. e., the surface that gives shape to portions of the upper that are visible in the finished shoe above the shoe bottom. Lasts which are used in the manufacture of stitchdown shoes usually have a somewhat rounded or beveled contour, at the junction of the bottom face and the upper-shaping surface, and as disclosed in the above-mentioned Letters Patent the tacks are driven in this portion of the last at such inclinations to'the bottom face of the last that the margin of the upper may be readily turned outward and a sole or insole placed on the bottom of the last in engagement with the outturned margin while some, at least, of the tacks are still in the last. The upper-fastening devices atthe sides of the forepart are supported on arms 20. (Fig. 1) which are swung inwardly toward each other to carry the devices into upper-fastening positions and which carry spring-operated driver bars 22 connected by means of substantially the same character as disclosed in the above-mentioned Letters Patent with tack drivers 24 inclined in the desired angular relation to the bottom face of the last for the purposes in view. The upper-fastening device at the end of the toe is supported on an arm 26 (Fig. 2) mounted to swing lengthwise of theshoe, this arm carrying a driver bar 28 connected to a tack driver 30 inclined relatively to the bottom facev of the last at substantially the same angle as the side tack drivers 24. Each of the several upper-fastening devices includes apairof tack fingers 32 that provide atack pocket from Which the tack is driven by the driver.

In order that the tacks may be driven in proper relation to the bottom face and the upper-shaping surface of the last the inward movements of the upper-fastening devices must be stopped with these devices in proper relation to the last. -Accordingly the front arm 26 carries a stop 34 arranged to engage the end of the shoe and thus limit the rearward swinging movement of the arm while also clamping the upper against the end face of the last to assist in holding the upper until the tack is driven. This stop is adjustable lengthwise of the shoe relatively to the armv 26 and is held in adjusted position by a' clamping screw 36. While differing in construction somewhat from the corresponding stop shown in the previously mentioned Letters Patent No. 1,916,275, it performs the same function as the stop therein shown. The means for limiting the inward movements of the upper-fastening devices that operate at the sides of the shoe is somewhat different from the disclosure of the above-mentioned-Letters Patent. As herein illustrated, each side clamp arm 16 carries a pair of clamp members 38 and 40 connected together by equalizing mechanism not shown in detail, but of substantially the same construction as used frequently heretofore in machines of the illustrated type and similar to the disclosure of Letters Patent No. 1,135,954, granted on April 13, 1915 upon an application of R. F. Mc- Feely. Each clamp member 40 clamps the upper upstate a ainst the side Qf. the last .below the locations wherethe side tacksare drivenandis mounted, on a blo ck,142 sw,iveled for movement about ,an axis extending heightwise of the last for automatic ad ustment to the lengthwise contour of the side of the last vas determined by engagementof the clampmember 40 with theshoe, as common heretofore in some machines of the 'illustratedjtype. ,Theunperefastening devicesateach side of the iast- includetwo plates 44 and 46 ,eachlofmhich serves as agllide for one-f the tack drivers 24 andas a supportfor the corresponding pair .of tack fingers 32 :the iconstruction .hereinshown the;n1ates 44, which .are included in the rearmost upp -fastening devices (i. e., the devices located iarthestiromthe endof the toe), are faston .the 613111520,whilelthe plates 46 included in the upper- Iastening devices that are nearer the end of the toe are pivoted at 48 on,the armsg for swinging movements Widthwise of the shoe and are urged inwardlybyspringsfim Each of the plates 44 and 46'carriesat its lower end a stop 52 arranged to engage -a shoulder on the previously mentioned side clamp block 42,. It will thus be seen'thatthe stops :52 carried by the plates 44 that are fast onthe sidearms 20 limit the inward swinging.

. movements of these arms and determine thepositions laterally of the shoe of the rearmost upperfastening devices. The stops 52 on theplates 46, on the other hand, by their engagement with the blocks 42, determine the positions of the foremost side upper-fastening devices, permittingthese devices to adjust themselves relatively to the shoe in accordance with the positions of the swiveled blocks -42 determined by the contour of the shoe. In the construction shown the clamp members 40 are made of metal for positive engagement with the shoe, so as to afford better insurance of accuracy in the positioning of the upper-fastening devices relatively to the shoe. Each stop-52 is threaded in theplate 44 or 46 which supports it to permitits adjustment laterally of the shoe by means of a screw driver and is clamped in adjusted position by a clamping screw 54 engaging two parts of a split bearing in which the threaded portion of the stop is mounted.

, To assist in holding the upper until the tacks are driven, each of 'the'side upper-fastening devicesin the construction herein shown carriesa clamp member 56 which clamps the marginal portion of the upper against the last above the clamp member 40 at the junction of the bottom face and the upper-shaping surface of the last and acts to some extent as a wiper upon the upper as it is movedinwardly; By reference to Fig. 4, which shows the two members 56 thatare carried by-the foremost side upper-fastening devices, .it will be noted thateach member 56 is supported on the plate 46below the tack fingers 32. Each member 56 is provided with two arms 58 that extend along oppositesides of the plate. 46, aportionvof one of the arms of the left-hand member being broken away in Fig. 4. The two arms 58 carry a pin 60-011 which there is mounted a roll 62 located in a slot 64 in the plate 46.- The member 56 has an upwardlycurved end portion for engaging the upper and has in this portion a slot through which the tack is driven, as shown in Fig. 6. A spring 66 connected to the plate 46 and to .a ,pin 68 that xtends between the two arms 58 urges the member 56 inwardly and posi-, tionsit normally with the rol1'62 at the inner end of the ,slot .64. Another spring'lO connected .to the plate 46 and the pin 68 :tends to swing the member 56 about the axis of thepin 60 in the/direction todepress the upper-engaging end portion of. the member. .such swinging .rnovementof the v member 56 is limited by engagement of portions of thearms 58 with the plate 46 :in slots 72 in the sides of the plate. It will thus be seen that when the plate 46 is carried inwardly toward the shoe by the swinging of the arm 20 the inner end of the member :56 engages the upper'held in tensionedcondition by the gripper before the arm 20 completes its inward swinging movement and that as the arm continues its movement the springs 66. and yield and thereafter by their tensionserveto urge the upper-engaging portion parted by the corresponding updraw lever 14 to close the jaws 74 on the upper and then to impart to them their upper-pulling movement. Similarly the toe gripper comprises jaws 78 which are closed. and operated bye. gripper bar 80 connected to the corresponding ,updraw lever. Located between the side gripper bars 76 and at the rear of the toe gripper bar ,80 is gripperspreading mechanism of substantially the same character as disclosed in the previously mentioned Letters Patent No. 1,029,387, whereby the side grippers are positioned initially at the proper distance apart to receive the margin of the upper at the sides of the last and the toe gripper also is presented in the proper initial position length wise of the last to receive the upper. This mechanismis not herein shown in detail, but includes members 82 which engage the inner faces of the side gripper bars 76 and a roll 84, which engages the rear or inner face of the toegripper bar 80, Associated with each of the side grippers are two overdraw, springs 86, only one of: which is shown in the drawings, these springs bearing against a plate 88 engaging the gripper on its outer side and thus tending to swing the gripper grippersto be swung inwardly by'the overdraw I springs to make way for the upper-fastening devices. V For the accomplishment of one of the objects of the present invention the construction herein shown is such as to cause the grippers to be swung somewhat inwardly by the overdraw springs in the course of the upper-pulling movements of'the' grippers heightwise of the last, prior 'tothe in-'" ward movements of the upper-fastening devices, Tothis end, each of theside gripperbars 76 has at its inner side a face 92 in engagement with the member82 and arrangedin such inclined relation to the direction of the upper-pulling move merit oflthe gripper heightwise of the last asto permit an -.inward swinging movement of the l gripper by the springs 86 proportional to the extent of the upper-pulling movement as the latter movement takes place. A similarly inclined face 94 on the toe gripper bar engages the roll 84 and performs the same function with respect tothe toe gripper. By reference to Fig. 4 it will be seen that by the cooperative action of the inclined faces 92 and the members 82 the side gripper jaws are positioned initially at such a distance apart that the jaws are located opposite the side faces of the last when in upper-receiving positions. As the upper-pulling movement of the grippers is effected they are swung inwardly by the overdraw springs as soon as the jaws rise above the plane of the bottom face of-the last, so that they draw the marginal portion of the upper inwardly over the edge of the last bottom before the upper-pulling operation is completed, as illustrated in Fig. 5. A similar action occurs at the toe end of the last. The portions of the upper that are to be engaged by the clamping members 56 are accordingly drawn inward over that portion of the surface of the last against which they are tobe clamped by these members before the latter receive their operative movements. The inward swinging movements of the grippers also carry the gripper-releasing members 18 farther from the upper-fastening devices. Better insurance than heretofore is thereby afforded that the marginal portion of the upper will be clamped and held in proper relation to the last before the members 18 are operated by the incoming upper-fastening devices to release the grippers from the upper, so as to avoid any loss of tension in the upper before the fastenings are driven. It will be understood that after such inward movements of the grippers as occur during the upper-pulling operation by reason of the inclined faces 92 and 94 on the gripper bars, still further inward movements thereof result from the retraction of the gripper-spreading mechanism to position them well out of the way of the upperfastening devices after they are released from the upper, as illustrated in Fig. 1.

It will be evident that the driving of the tacks precisely in the desired locations at the junction of the bottom face and the upper-shaping surface of the last requires that the last be accurately positioned heightwise relatively to the upperfastening devices; For this purpose the machine is provided with a work rest comprising a member 96 arranged to engage the bottom face of the last near the end of the toe and members 98 arranged to engage the bottom face of the last farther rearwardly at the sides of the forepart. The end member 96, as in prior machines of the illustrated type, is mounted on a bar 100 which is adjustable lengthwise of the last in a holder 102, the bar as herein shown being held in adjusted position by a screw 104 threaded in a plate 106 on the holder 102 and having a pointed end 108 cooperating with rack teeth 110 on the bar. The member 96, is pivoted at 112 on thebar 100 for swinging movements heightwise of the last. A spring 114 tends to swing the member in one direction, and a screw 116 carried by the member and bearing on the bar 100 cooperates with the spring to determine adjustably the position of the member. The side members 98, in the construction herein shown, are adjustable relatively to the end member 96 in directions heightwise of the last, and for this purpose they are mounted on a support 118 which is itself mounted on screws 120 on the sides of the holder 102 for swinging movement about an axis extending widthwise of thelast." A spring 122 tends to swing the support 118'v in one direction, 7 and cooperating with the spring to determine adjustably the position of the support there is a stop screw 124 which is threaded in the support and abuts against the bar 100.

By means of the screw 124 the last-engaging portions of the members 98 may accordingly be adjusted heightwise of the last.

In view of the fact that the bottoms of lasts at the forepart are frequently curved more or less laterally as well as lengthwise, the construction herein shown is further such that the members 98 engage the bottom face of the last in locations as close as is practicable to the side edges of thelast bottom, as herein illustrated at less distances from the edge of the last bottom than the width of the marginal portion of the upper that extends beyond said edge. As illustrated, moreover, these members engage the last in locations opposite the points where the rearmost side tacks are driven, i. e., in locations directly inward over the last bottom from these points, so as to provide for particular accuracy in the driving of the rearmost tacks which in practice are sometimes permitted to remain in the shoe and last until a later stage in the manufacturing operations than the foremost side tacks and the end tack. In order that the members 98 may be accurately positioned in operating on lasts of different sizes, the construction shown is such that they are pivoted on screws 126 on the support 118 for swinging movements widthwise of the last. A spring 128 located between the members 98 forwardly of the points where they are pivoted tends to swing their last-engaging ends apart. To cooperate with the spring 128 in adjusting the members 98 widthwise of the last there is provided a screw 130 which is threaded inthe support 118 rearwardly of the pivot points of the members and has a conical end portion that engages inclined faces on the members, the screw thus acting as a wedge member in opposition to the spring 128. By adjustment of the screw 130 the last-engaging ends of the members 98 may accordingly be positioned at the desired distances apart for operating on lasts of different sizes. It will be understood that the member 96 is also adjusted, to engage the last as near as is practicable to the point where the end tack is driven, and that by adjustment of this member heightwise of the last as hereinbefore described the desired accuracy with respect to the location of the end tack is obtained. It will be evident that when the members 96 and 98 are adjusted to determine accurately the position of the last relatively to the devices that drive the end tack and the rearmost side tacks, the last is positioned also with sufficient accuracy relatively to the devices that drive the foremost side tacks.
