METHOD ANDjMIEANS FOR POSITIONING LAS'IS AND THEIR SHOE MATERIALS.

Application filed February 12, 1925. Serial No. 8,717.

This invention relates to the positioning of lasts and their shoe materials relatively to means for operating on the materials. The invention is herein illustratedin its application to the operation of lasting the toes of shoes, for which it has very important advantages, but it will be understood parthat the invention is not limited to that ticular part of shoe manufacture.

In lasting the thes of shoes in machines of well-known types provided with toe-embracing wipers'that are shaped to conform substantially to the contour of the toe when they are closed about the toe, it is important for satisfactory results that the shoe and the wipers be positioned relatively to each other with a high degree of accuracy, both' in respect to the relation, as to angularity, between the bottom face of the shoe and the plane of the wipers in the wiping of the upper inwardly over the insole and in. respect to the relation between the end and the sides of-the toe and the edges of the wipers. Machines have accordingly been provided with means for adjusting the shoe posi-' a tioning means and the wipers in various ways, and it is necessary for the .operator to make use of some or all of these adjustments in changing from one size or'style, of, shoe to another, and also frequently to make one ormore adjustments to compensate for variations in position as between different shoes of the same size and style. This takes much of the operators time, with consequent limitation in the amount of production. Since, moreover, there is nothing to afford the operator any'very definite indication of the best relation between the shoe and the wipcm, the quality of the results obtained in the lasting operation depends very largely upon the operators care and judgment. Lack of uniformity in the product and frequ ent deviations from the best workmanship -are therefore almost inevitable even with the most highly skilled operators.

Inone import-ant aspect the present invention provides a method by the use of which lasts and their shoe materials are p0 sitioned quickly and accurately in the best relation to the means for operating on'the materials without the need for any high degree of care. or skill on the part of the operator, thus improving the quality of the work, increasing-the output, and at the same on the machine. F or the'purposes in view,

the last may be provided,'a s herein shown, with a plurality of holes in the bottom of its forepart and the machine may have a plurality of pins to enter theseholes and thus position the last. It'will be understod that the holes will be arranged in a definitely predetcrmined relationto one another and to the edge contour of the last bottom, and the pins will be arranged in a correspondingly predetermined relation -to one another and also,

as herein illustrated, in a predetermined relation to the toe wipers such that when the wipers have been advanced and closed a definite distance their wiping edges will conform substantially to the contour of the toe a of the shoe-at the edge of the shoe bottom.

Y The position of the last in respect to lengthwise and lateral bodily movements and in respect to lateral swinging movements is thus definitely determined. Further to insure a definitely predetermined relation, as to angularity,between the bottom face of the forepart of the last and the plane ofthe wipers'in the wiping of the upper inwardly over the bottom of the last, the pins and the holes in the last, as the invention is herein exemplified, are utilized to determine the position of the last in respect to tipping movements about axes extending lengthwise or laterally thereof, the end faces of the pins engaging the last at the bottoms of the holes and the latter extending into the last to predetermined relative depths calculated in accordance with the relation, as toangularity, which it is desired that the bottom of the last or shoe shall assume to the plane of the wipers. For thepurpose of this part of the invention, it is contemplated that at least three pins will be uti.

lized, with a corresponding number of holes in the last. It will be recognized that the pins will determine also the position of the last as a whole in respect to movement in the direction of its height, and preferably the last will be held securely in the position determined by the pins. 7

lVherc, as in toe lasting, the shoe materials under treatment include an insole, the insole will be provided with holes in its forepart which corres mud to the holes in the last and receive tie last positioning pins, the holes in the insole, formed in predetermined relation to its edge contour, also atfording in co-operation with the holes in the last an accurate indication of the proper position of the insole on the last in assembling the parts. After the insole has been positioned so that its holes aline with the holes in the last, it may be tacked to the last in the usual way.

In addition to its method aspects the invention, in still other aspects, resides in improved apparatus useful in carrying out the method and characterized, for example, by the provision, in a machine for operating on shoe materials on a last, of a plurality of lastpositioning pins, such as those above referred to, for positioning the last relatively to the operating means, the machine herein shown having also means for clamping the last against the ends of the pins. The invention further provides features of novelty both in lasts and in insoles adapted for use in the practice of themethod.

The invention will now be more particularly described by reference to the accompanying drawings and pointed out in the claims.

In the drawings:

Fig. 1 is a plan view of toe-embracing wipers and shoe positioning means, illustrating how the last and its shoe materials are positioned in a toe lasting machine by the method of this invention through the use of one form of positioning means that may be utilized in practicing the method;

Fig. 2 is a cross-section through the last and shoe and through the shoe positioning means and the wipers at one stage in the operation of the wipers on the shoe';

Fig. 3 is a view of the parts shown in Fig. 2, partly in side elevationand partly in section longitudinally of the shoe;

Fig. 4 is a view on a smaller scale than Figs. 2 and 3 of a last utilized in practicing the method, illustrating also how the positions of the holes in the last may be determined; and

Fig. 5 shows an insole utilized in the practice of the method.

The toe lasting mechanism show for illustrative purposes in Fig. 1 comprises toeembracing wipers 2 mounted on wiper holders 4 which are movable in curved guideclosing movements to the wipers.

ways formed in a wiper carrier (i mounted for movements lengthwise ofthe shoe. The wiper carrier 6 is provided with pinions 8 engaging rack teeth formed on the wiper holders 4 and operated by a rack bar 10 to close the wipers about the too. This mechanism is of the same construction as shown in my co-pending application Serial No. 698,099, filed on March 10, 1924, which further shows and describes in detail operating mechanism for imparting advancing and It is sufficient for an understanding of the present invention to st: te that, as usual in machines of the same general type, the wipers receive advancing movement lengthwise ol the shoe and closin movements laterally of the shoe such that for a given amount, of advancing movement there is a predetermined amount of closing movement. As usual also in toe lasting machines, the wipers are shaped at their wiping edges substantially to conform to or to lit the contour of the toe of the shoe when they have been advanced and closed about the toe substantially to the edge of the shoe bottom ready to begin the. wiping of the upper inwardly over the insole. For thebest results, differently shaped wipers will preferably be substituted for different shapes and sizes of shoes, although under some conditions it is practical to use the same wipers for several different sizes. To accommodate the wipers to different widths of toes, means may be provided for adjust.- ing the wipers about the axis of their closing movement, such means being described in the co-pending application above referred to. As shown also in said a n'ilication, the wipers will preferably be mounted for movements heightwise of the toe to upwipe the upper to the edge of the shoe bottom and later to press the upper down upon the margin of the insole, as well as for tlllYtllll, ing and closing movements to wipe the upper inwardly over the insole.

It will be evident that. if the wipers are to conform with substantial accuracy to the contour of the toe when they have been advanced and closed a definite distance. the shoe must be in a definite predetermined relation to the wipers at that point in their operation, and it will also be evident that satisfactory results in the wiping of the margin of the upper inwardly over the insole require a certain predetermined relation, as to angularity, between the bottom face of the forepart of the shoe and the plane of the wipers. Generally speaking, it is desirable that the wipers shall bear evenly upon the margin of the upper about the end and along the sides of the toe with. substantially or approximately equal pressures in these different locations, although it may be desired under some conditions tor the wipers to bear on the upper with somerespects is accurately predetermined, so that what greater pressure in one location than in others, for example at the end of the toe as compared withthe sides of the toe. By the present invention the position of the last and its shoe inaterals in these different tom of its forepart, to be utilized in posi-.

tioningthe last in respectto lengthwise and lateral bodily movements and lateral swinging movements, and also in respect to lengthwise and lateral tipping movements. The

. holes 14 are shown as formed in metal bushings 16 which are inserted in holes 17jtormedin the wood of the :last to receive them.

While the invention isnot limited to the use of three oles in the-last, as herein shown,

it is consideredthat this number of holes is adapted to give the best results in positioning the-last in the ditlerent'respects desired.

It will be observed that one of the holes 14 is-located near the end of the toe, substantially midway between the opposite sides of the toe, and that the other two holes are-located farther rearwardly, for example about 'where the tip seam will come on the shoe, and are'near the oppositesides of the toe.

' It will be evident, from further consideration hereinafter of the manner in which the holes 14 inthe last are utilized in positioning the work, that the distances between the holes and their relations to one another and to the contour of the last may be varied,

- holes 14 in the last bear to the edge of thewithin limits, as long as the elements (:0- operating with the holes in positioning the work are correspondingly positioned in relation to one another and, to the means for operating upon the shoe materials, although it is preferable that the holes be located .as

near to the edge of the last bottoni as it is.

practicable to position them. The distances of the holeslrom the edge of the last bottom will, however, be so determined, on welt work, that corresponding holes18 punched in the forepart of the insole 20 will be positioned'inside of the rib or lip 22 of the insolo. It will be understood that the holes 18 in the insole will be located in the same relation to the edge of the insole that the last bottom. It is preferable that the holes 18 in. the insolebe located near the lip or. rib, but since it is contemplated that, for

convenience, several different 'sizes of lasts may have holes the same distances apart. the holes in the insole maybe located nearer to the rib in some sizes than in others. A machine that may be utilized for punching the holes in the insole is shown in a copending application, Serial No. 15,093, filed on March 12, 1925.

the bottom face of the last.

It is important that the holes 14 be located in the same relation to the edge contour of the last bottom in all lasts of the same size and style, and to this end it is contemplated that the different lasts will be positioned inthe. same relation to a group of tools provided for boring the holes17 in the-wood of the lasts, by the use of suitable gaging mechan sm comprising, for example, members 2-]; shown dlagraniniatically n Big.

-1- l'or engaging the last at the end and the sides of the toe. In view-0t the manner in which the holes 14 are utilized in determining the relation of the bottom face of the forepart of the last to the plane of the wipers, it is important to gage accurately the depths of the different holes. Qonveniently the metal bushings 16 provided for inscrtion into the holes17 in, the wood of the -last may be all alike, with the inner ends of the toe lasting operation it is important to determine the relation between the plane of the wipers and on ya comparatively narrow margin of the shoe bottom aboutthe end and along the sides of the toe, and it is, therefore,- with reference to this particular portion of the bottom face of the last tha't'the depths, and likewise the directions, of the holes 17 in the wood of the. last are determined. Practically this may be accomplished by the use of gages contacting with the bottom face of the forepart of the last near the edge of the'last bottom at the end and the sides of thetoe, 'and in Fig. 4 the age members 24 which engage the last at the end of thei'oe and in the approximate location of the tip seam ot' the shoe are'illustrated as shaped for thus engaging the bottom of the last and additionally determining the position of the last,.relatively to the tools for boring the holes 17, in respect to lengthwise and lateral tipping move ments. These gages thus determine a plane on the last represented by the dotted lines A and B on Figs. 2 and 3 respectively, which may be termed the plane of the forepart ot' the last bottom, and the depths and directions of the holes 17, and consequently of the holes 14, will bear a predetermined relation to this plane. In view of the fact that lasts are usually more or less convex on their bottom faces at the forepart. as illustrated, it will be evident that the different holes will usually not extend into the last for equal distances relatively to adjacent portions of The metal bushings provided will be of such lengtlras to allow for such variations in depth, and after they have been seated at the bottoms of the holes 17, they will be ground oil so as to be flush at their outer ends with the bottom surface of the last. A machine that may be .utilized for boring the holes in the lasts and for gagin accurately the locations and depths of the holes in the manner illustrated diagrammatically in Fig. 4, and also for inserting the bushings, forms the subject-matter of a copending application Serial No. 14,756, filed on March 11, 1925.

To co-operate with the holes 14 in positioning the last and its shoe materials, pins 26 are utilized to project through the'holes 18 in the insole and into the holes 14 in the last. These pins, in the construction herein shown, are fast on a plate 28 which is detachably secured by means of a bolt 30 and a locating pin 32 to an arm 34 fast on the frame of the machine. The shoe is supported and the last is clamped up against the ends of the pins 26 by means of a toe rest '36 which inay be operated in the manner disclosed in the co-pending application Serial No. 698,099 hereinbefore mentioned.

The pins 26 are so located in relation to the wipers that when the wipers have been advanced and closed the correct distance for their wiping edges to conform to the shape of the toe of the shoe at the edge of the shoe bottom, the pins bear the same relation to the wiping edges that the holes in the last bear to the lateral periphery of the toe of the shoe, and thus the shoe is positioned in exactly the right relation to the wipers in respect to lengthwise and lateral bodily movements and lateral swinging movements. It will be further understood that the endsof the pins 26, seating against the metal bushings 1G, determine the relation, as to angularity, between the bottom face of the forepart of the shoe and the plane of the wipers-in the overwiping operation. The end faces of the pins may lie, i or example, as herein shown, in a plane which is parallel to the plane of the wipers when the wipers are.in position to wipe the upper inwardly over the insole, and if the plane determined by the inner ends of the holes 14 is parallel to the plane of the forepart of the last bottom represented by the lines A and B, as also herein shown, the

latter plane will be parallel to the plane of tlie' wipers in the lasting operation and the wipers will bear evenly on the upper with substantially equal pressures at the end and the sides of the toe. It will vbe understood that any one of the pins 26 could be longer than shown in the drawings, provided the hole 14 co-operating with the pin were cor-.

respondingly deeper, without affecting the position of the last, although it is preferable, for convenience, that the end faces of the pins lie in a plane that is parallel to the plane of the wipers in the overwiping opera tion. It will be further understood that, having regard to the distance that the pins 'extend below the plane of the wipers, the

holes in the last will be of such depthsas o position the last at the proper height relatively to the wipers. 1

By suitably .gaging the position of the last relatively to the tools for boring the holes in the last, the holes may be so formed that the plane of the forepart of the last bottom, represented by the lines A, B, will 'notbe in parallel relation to the plane determined by the inner ends of the holes and, therefore, will not be in parallel relation to the plane of the wipers in the overwiping operation. In this way there may be determined such a relation between the shoe and the wipers as to cause the wipers to bear on the upper materials with harder pressure at the end of the toe, for example, than at the sides of the toe, as is desirable on some kinds of work. It will be understood that after it has been determined what pressure applying relation between the wipers and the different portions of the toe is most desirable, all the lasts ofthe same size and style for a line of shoes will be positioned in the same relation to the boring tools so that the differentushoes will be positioned in standardized relation to the wipers.

For wide variations in sizes it will \be preferable to vary the spacing of the holes 14, and different sets of pins 26 mounted on plates 28 will be correspondingly provided for attachment to'the arm 34. Preferably the hole 14; at the end of the toe will be positioned at the same distance from the end face of the last in all sizes of lasts, so that the wipers will be advanced the same distance to bring them up to the end of the toe irrespective of the size of the shoe. It will then only be necessary to adjust the wipers toward or from each other for dillcrent widths, as may readily be done, for example, by the mechanism shown in the copending application Serial No. (SQHJM).

In assembling the insole on the last its holes 18 will be brought into alinement with the holes 1-1 in the last and tacks may then be driven in the usual way to fasten the insole. In performing the toe lasting operation all that the operator has to do in positioning the shoe is to bring it into position for the pins 26 to enter the holes 14, and with the shoe clamped up against the pins by the toe rest 36 assurance is afforded that the shoe is in exactly the right position for the operation of the wipers without the necessity for the operator to give any attention to relative adjustment of the shoe and the wipers, assuming that the wipers have already been adjusted in proper relation to the sides of the toe for the size of shoe upon which the machine is to operate. A further very important advantage is that the pins 26 hold the shoe unyieldingly throughout the lasting operation against pressures directed thereof.

While the invention is herein illustrated lengthwise and laterally in its application to toe lasting operations, it

will be understood that the invention is not thus limited but is likewise applicable to the positioning of shoes for pulling-over and lasting operations and for other operations where it is desirable to position the'shoe in accurately predetermined relation to the means for operating upon it. It is likewise to be Understood that the invention isnot limited to'welt shoe work, but is applicable to the manufacture of various types of shoes.

The combination of toe-embracing wipers having wiping edges formed sub stantially to fit the contour of the toe of a shoe when they are closed about the toe, a group of last-positioning pins arranged with their end faces in a plane in predetermined relation to the plane of the wipers when the wipers are in position to wipe the upper inwardly over the insole, a last having in the bottom of its forepart a plurality of holes of predetermined relative depths to receive said pins, and means for supporting the last against the ends of the pins in said holes to determine the relation, as to angularity, between th bottom face of the torepart of the shoe and the plane of the wipers in the overwiping operation.

St. A last having in the bottom of its t me part a plurality of holes located respectively near the end of the toe and near the opposite sides of the last to receive last- POiSlllOIlllltI members for positioning the last relatively to means for operating on the shoe materials.

35. A last having in its bottom portion at one end thereof three holes located at points that are out of alinement with one another for use in positioning the last relatively to means for operating on the shoe materials.

36. A last having in the bottom of its forepart a plurality of holes extending inwardly to relative depths determined by reference to a plane defined by three points on the bottom of the last at the end and at the opposite sides of the toe respectively for use in positioning the last relatively to means for operating on the shoe materials.

37. A last having in the bottom of its forepart three holes locatedat points that are out of alinement with one another and with their inner ends in a plane substantially parallel to a plane determined by three points on the bottom of the last at the end and at the opposite sides of the toe respectively.

38. A last having in the bottom of its forepart a plurality of metal bushings with holes extending part way only thcrethrough .for use in positioning the last relatively to means for operating on the shoe materials. 51). A last having in the bottom of its foreparta plurality of metal bushings located respectively near the end of the toe and near the opposite sides of the last and provided with holes extending part way only therethrough, said holes extending into the last to relative depths determined by reference to a plane defined by three points on the bottom the last at the end and at the opposite sides oi the toe respectively.

4.0. An insole having in the bottom of its forepart a plurality of gage holes extending through it and located respectively near the end of the toe and near its opposite sides.

41. An insole having in one end portion at least three gage holes extending through it and located at points that are out of alinement with one another.

42. A welt shoe insole having in the bottom of its l'orepart a plurality of gage holes extending through it and located respectively near the. end of the toe and near its opposite. sides, said holes being located farther inwardly from the edge of the insole than the welt-attaching lip or rib.

In testimony whereof I have signed my name to this specification.
