10 Claims.

This invention pertains to the manufacture of footwear, and relates more particularly to an improved process of lasting shoes. In my Patent No. 1,919,657, dated July 25, 1933, I have disclosed a novel method 'of lasting the end portion of a shoe, wherein after the marginal parts of the shoe upper have been wiped-in by the wipers of a bed lasting machine, the wiped-in material at the end of the shoe, for example, at the toe, is subjected to pressure, with or without heat, by means of a plate interposed between the wipers and the shoe bottom, said plate being forced against the. shoe bottom by downward movement of the wipers. In its preferred embodiment, said prior method also includes the employment of a suitable adhesive for securing the wiped-inmai'gin of the upper in" lasted position, so that no independent fasteners, such as tacks, staples, or the like, need remain at this part of the finished shoe.

Ordinarily the lasting of the forepart of the shoe and the shank or side portion as well, is carried out as an operation separate from and independent of the end (toe or heel) lasting, such side lasting being quite commonly accomplished by the use of a staple-lasting machine, which secures the edge of the upper to. the insole by means of wire staples so driven that they do not intentionally penetrate through to the inner surface of the insole.

In recent years much effort has been expended by the makers of certain types of shoe in educating the public to the belief that shoes wholly devoid of metallic fasteners are to bepr eferred-be fore others. In so far as the toe and forepartportion of the shoe are concerned, such educational, campaign is probably justifled, since maximum flexibility, comfort to'the wearer, freedom from intruding tack points or other metallic elements, and a smooth, level, unblemished and unweak ened insole at those parts of the shoe on which. the toe and broad ball portion of the foot rest, are only attainable by substantial elimination of metallic fasteners at this part'of the shoe. However, at the shank or side portion of the shoe, metallic fasteners, even including tacks, are of far less consequence and may, in some instances, be regarded as beneficial, since at this part of the shoe the foot exerts little pressure, and in shoes. of the high archvariety employing French heels,

a maximum degree of rigidity, stiffness and integ-,

rity of the constituent parts of the sh9e,bottom is requisite at the shank to prevent" the latter from breaking down in Thus staples, tacks or other such independent fasteners may well be tolerated and even welcomed at the shank or side portion of the shoe, as contributing to the desired stiifness at this point, while on the other hand, as already noted, the forepart and toe should be as free from such fasteners'as is practicaL.

- The principal objectof the present invention is to provide a shoe lasting method of commercial practicability; whereby the forepart and toe portion of the shoe may be lasted, preferably as a single operation, without the employment of metallic fasteners other than the usual small number of pulling-over tacks, thereby substantially preserving the integrity of the insole at this portion of the shoe, and without resort to the application of a multitude of temporaryfasteners, such as tacks, or the channeling of the insole, or its penetration by stitches or the like, as an intermediate step in the process, all of such expe'dients as just referred to, detracting from the strength of the insole and making it necessary to employ an insole of unduly great thickness. At the same time, in accordance with the present invention, all defects in the upper surface of the insole,--for example, bumps, ridges, discoloration, holes, etc., such as result from the employment of metallic fasteners, stitches or the like are eliminated; so that, if desired, the upper surface of the insole may be left exposed to view in the finished shoe, thereby avoiding the necessity of covering this .portion of the insole with a sock lining.

In attaining the desired object, I follow a procedure which, so far asthe extreme toe end portion of the shoe is concerned, somewhatresembles the operation described in my aforesaid application for Letters Patent, but modified in certain particulars, thereby to permit the employmentof additional steps which result in lastins-in, flattening, and securing the margin of the upper along the entire forepart of the shoe forward of the shank, all as stated, without resort to permanent metallic fasteners, or in fact any substantial number of temporary fasteners.

For the practice of the improved method, I preferably modify the usual bedJasting machine, in respect at least to the shape and dimensions of thelasting wipers, thereby to enable the machine not only to wipe-in the toe portion of the shoe, but also substantially the entire forepart thereof. Thus, for example, I prefer to employ wipers which are extended rearwardly, as compared with usual wipers, so as to reach well toward the ball portion of the shoe bottom, and in certain I I instances even to the shank. In the latter case I may resort to wipers having relatively movable tail .or rear portions operative to wipe the upper material inwardly and forwardly, so as to stretch of hand stretching or pulling at this made mutually adhesive, so that when pressed firmly together the upper is reliably retained in lasted position relativeto the insole, in readiness for the subsequent application of the outer sole.

Following the present process, the shank or side portions of the shoe may be lasted in any acceptable manner, for example, by the use of tacks, staples, or other independent fasteners, or even by cement, whenever the latter method is found feasible and practical, and the outer sole may be attached in accordance with any desired method or by any suitable means, such for example, as McKay sewing, cement, or the like.

Referring to the drawings, the numeral I designates an insole which may be of any suitable material and of any appropriate construction. Preferably this insole is of substantially uniform thickness throughout and, if desired, may be provided with a metallic shank piece 2 secured to the main body of the insole by means of staples 3 or any other suitable manner. The insole may, for example, be of the general type disclosed in either of the patents to Ray, Nos. 1,641,782 or 1,794,245. I

This insole, of whatever form or construction, is assembled upon a last L (Fig. 8) with an upper U, the latter being of any desired typeandstyle and comprising, for example, an outer element 4 (Fig. 3) which may be of leather, cloth, or other suitable material, and which, in accordance with a common practice, may include a doubler such, for example, as a layer of textile fabric cemented to its inner surface for strengthening purposes. .The upper may also comprise a stiffener 5, such as a box toe, at its toe portion and may also include a stiffener, (not shown) such as a counter, at its heel end. Ordinarily the upper will also including a lining 6 of any appropriate material.

After assembly upon the last, the upper is properly spindled, that is to say, moved relatively to the last until it is in proper registry with the last, and then pulled'over, and the toe portion of the upper is secured to the last I by means of temporary pulling-over tacks I, 8, and 9, the tacks 9 usually being located at the sides of the forepart at ornear the ball portion of the shoe; The upper is now lasted-in at the shank portion in any appropriate manner as, for example, by the use of staples II in accordance with the well known Littleway process, or. if preferred, by means of tacks H, as indicated in Fig. 1 Alternatively the shank portion of the upper may be secured in lasted position without the use of independent fasteners such as staples or' tacks, for instance, by means of cement, as illustrated at I1 in Fig. 1'.

After having performed these preliminary lasting operations, the last is mounted in a 'bedthose usually employed and, in fact. long enough to reach from the toe portion of the shoe along the margins of the forepart substantially to the shank portion. Having installed wipers of this type in the machine and having mounted the last upon the supporting spindle in usual manner, the

operator actuates the wipers in usual manner to stretch the upper taut about the forepart of the last, this being accomplished by-an upward movement of the wipers while their edges are pressed against the upper. At the conclusion of this operation, the wipers are held firmly in contact with'the upper at about the plane of the insole while the operator removes some at least of the pulling-over tacks, for example, the tacks 1 and 8.

This is usually done by means of a tack-pulling tool l4. formed at the end of one handle .of a pair of lasting pincers. It is preferred, however,

, to leave the tacks 9 in position in 'orderwith trims away thesurplus upper material (Fig. 3),-

in particular the surplus lining 6 and stiffener material 5, preferably leaving the latter substantially flush with the surface of the insole. Under some conditions this step in the operation may be omitted, particularly if the upper be cut "scant with small lasting allowance, and especially if the lining material and the stiffener be scant or entirely omitted. r v

The lasting wipers are now manipulated in the usual manner, that is to say, are repeatedly advanced and retracted so as to .wipe-in, the marginal portion of the upper onto the'bottom of the insole. This motion of the wipers causes the marginal material at the toe portion to be disposed in pleats l6, and as the end portions of the wipersextend beyond the pulling-over tacks 9," the result of this wiping operation is to bend overthese tacks 9 into the position-indicated in dotted lines in Fig. 4.

The operator now retracts the wipers, as shown in Fig. 5, but without withdrawing their inner edges completely from on the edges of the insole. This partial retraction of the wipers leaves free the extreme edges of the marginal portion-of the upper, but sincethe wipers are not fully retracted, the upper is held firmly and in fully stretched condition about the last and in contact with the extreme outer margin of the inner sole. The operator now opens out the thus freed edge portion l1, ll of the upper and applies to the exposed inner surface oflthe upper material, as by means of a brush l8, or preferably and more effectively by means of a pressure spraying device, a'suitable adhesive orcement, which may be either hot or cold, as desired. For the intended purpose I have found that rubber latex produces most excellent results. The adhesive'is applied, not only'at the toe portion, but also along the edges down as 'far as the, shank, and while a small area of the margin, where it is held by the tacks can not well' be reached directly by the b or pressure spray, the adhesive applied to adjacent portions will flow freely enough to penetrate beneath these,parts of the upper during successive steps in the operation. Alfematively the adhesive may be applied to the insole instead of the upper alone,- but preferably,

and as a matter of practice, the introduction of adhesive bymeans of a brush into the angle between the insole and upper, coats the surfaces of both these parts.

At this stage also the operator seizes the edge of the upper at the ball portion of the shoe and, by a twistingand pulling action, draws the upper snugly about the last and over onto the insole.

The wipers are now quickly advanced over the wiped-in material, as shown in Fig. "6, in a final wiping operation, thereby turning the free edge portion I1, I 'l of the upper down again onto the insole and bringing the adhesively coated surfaces of the upper and insole firmly into contact. The 'pers are now momentarily lifted and slightly retracted, as indicated in Figs. 7 and 8, and a suitable presser device such, for. example,- as that more fully disclosed in my Patent No. 1,919,660, dated July 25, 1933, is slipped, by longitudinal movement parallel to the insole, between the lifted wipers and the bottom of the shoe. The wipers are now quickly depressed, thereby iii forcing this presser deviceflrmly into contact 1 with the shoe bottom.

As illustrated, this presser device comprises a plate IQ of such shape and dimensions as substantially to cover the wiped-in marginal upper material along the entire forepart of the shoe, from the toe back as far as the shank. This presser plate l9 may, if desired, be furnished with an auxiliary and resilient presser element 20 extending along its marginal portions, and the "presser member also preferably comprises an electricalheater 2|, and is furnished with a handle 22 for use in manipulating it. Having quickly introduced this presser device with its heated plate I9 beneath the wipers, and having then quickly brought the wipers down upon it so as to exert substantial pressure, the parts are left in this position, as indicated, for example, in Figs. 9 and 10, until the adhesive has substantially set, thereby firmly to unite the marginal portion of the upper to the bottom of the insole. The wipers are now retracted, as indicated in Fig. 11, and the presser device may be removed, thereby leaving the bottom of the shoe substantially in the condition illustrated in Fig. 12, wherein the marginal portions ll of the upper, forward of the shank, are firmly secured to the insole by means of adhesive, while at the forward end or toe portion the upper is disposed in pleats l6 which have been flattened by the application of the heat and pressurev as above described, so that the whole bottom of the shoe is substantially flat .and level. If it be found that the upper is too full at the toe portion to permit sufficient flattening merely by pressure, as above described, the pleated portion may beshaved oif subsequent to the earlier wiping,-for example, after the step outer sole S. This outer sole may be secured by stitches, cement, or any other suitable manner.

As illustrated in Figs. 13 and 14, I may employ for the wiping operation special wipers l2 and l3 having tail portions l2 and. I3 which-are pivotally secured to the main portions of the wipers by pivot-members 2|. .Thse tail'portionsare 25- furnished with rigid arms 25 having at their forward ends contact rolls 26 adapted to engage the sides of the lasted upper. Whensuch wipers are employed and are moved inwardlyinto wiping position, the roller members 26, by contact with sides of the shoe, cause the tail portions 12 and l3 to be swung inwardly into the broken line position of Fig. 14, thereby exerting a forward and inward straining or stretching action on the upper so that the employment of lasting pincers, as indicated in Fig. 5, for example, may not be necessary, the entire operation from toe to shank being performed by the use of the wipers alone.

In accordance-with a slightly modified procedure the insole I, as shown in Fig. 1*, may first be prepared by providing its under surface with a border-of adhesive B which may be of .a type which, after application, becomes dry and nonsticky; for example, this may be a border of a pitch or thermoplastic cement, which becomes sticky when hot and becomes hard and dry when cold, or some other material such, for example, as cellulose acetate, which becomes stickywhen subjected to a suitable solvent. If such an insole be employed, it is assembled onthe last with the upper in the same way as above described, and then at some stage during the wiping operation, either at a preliminary point or after the final Wiping, this adhesive may be rendered active or sticky by the application of heat or a suitable solvent. The parts will then be held under 'pressure while this adhesive resumes its set or hard condition, thereby firmly to unite the parts.

While I have herein described certain desirable steps in performing my improved process and certain modifications, all falling within the scope of my invention, I wish it to be understood that the invention is not necessarily limited to these particular steps as above described, nor to'the exact sequence of operations suggested, but that,

all variations thereof and substitutions of equivalent steps are to be regarded as falling within the purview of the invention as expressed in the appended claims.
