MACHINE FOR FORMING UPPERS 0F BOOTS AND SHOES.

Application filed August 5,

To all 11:15am it may concern:

Be it known that'I, Kant EXGEL, a subject, of the Emperor of Germany. residing at Revere. in the county of Sult'oll: and ('onnnonweaith-of Massachusetts, have invented certain Improvements in Machines lul Forming tippers of Roots and Shoes, of which the following description. in connech is a specification. like reference characters on the'drawings indicating like parts in the several figures. i

This invention relates to ipachinesfor use in the manufacture of shoes having ontturned uppers. Shoes of this type-are commonly known to the t 'ade as stitch-downs the upper of a shoe of this type being attached to the sole by stitches. or other fastenings. which are passed through the outt-urned portion of the upper and through the sole.

Although the stitch down shoe is one of the older types of shoes, the'manufaeture and commercial exploitation of this shoe, particularly in the better grades. has not been undertaken upon a large scale up to the present time. This has been due largely to the fact that the advantages to be gained in manufacture of this shoe by reason of the simplicity of the sole-attaehing operation have been more than (ounterbalancetl. by the difficulties attending the preparation of the upper for this operation. Many methods have been devised for preparing the up pet's of such shoes for the $Ul8-tll'titt'illfif operation. The greater num er of sum methods involve shaping the upper over the Specification of Letters latent.

iast in approximately the usual waythe ehie -.lill'erenee being; that in the ease of flit.etllfit-(ltizfil shoe upper the upper is turned out around the bottom edge of the last instead of being turned in. These methods in practical application hare .oeen found as a rule unsatisfactory. their employment resulting either in a pooi-l y-s;=: iped upper or in a poor]y-tormed flange for the attaehmenfot' the sole. They are al o waste- 1 ful of material.

One of the chief dittienlties atteudi E In! the sole-ataching operation by the simple lasting method is that of forming a smooth and properly curred out-turned flange. 331911 En-mg nothing upon the last which xvii? aid Patented July M5, 1911.

t in the formation of this flange or to With-i1 the flange may be attached alter 't has b en formed. Another dillienlty to be )YOII'Uhip is that of properly gathering in the leather about the toe portion of the upper to form the bulge over the flange at the toe. whi h is desirable both for appearance and H ll.- fort. and atthe same time leaving; this partof the upper smooth. This dillieulty i ircreased inthe case of the forum: n of a stitehalown upper by the Iltt'OMilI) of forur ingrat the same time abom the toe a smooth flange. or at: least a flange lying in one plane.

The purpose of the present invention i t provide a mechanism which will obviate the ditlicult es hereinlwfore pointed out and whielfiwill form from a flat toe blank of leather or other flexible material a prop- 91-15 shaped toe. ha ing an out-turned flange for sole-attaching purposes. The invention has also for its aim the aeeomplishment of this purposeby a exunparatirely simple mechanism which in its operation utilize a novel method of forming the toe i'or'a shoe upper. this method being (thetaa and claimed in U. S. Letters Patent No. 947.595, dated Feb. 1, 191.0.

The in entionaimsfurther to prmide a mechanism for use in the manufacture of stitch-clown shoes which combines ellieient means for shaping the toe portion at a stitch-down shoeupper. together with likewise etlieient means for forming upon the upper an out-turned flange. said two means operating in such manner that neither can injuriously ait'eet the work of the other. 7

Another object of the invention is to provide a mechanism of the kind just descrioed in hich the two aneans t'tl ill\rllti"ill sreh manner that 'e u-h aids in the perforimmce of the work oi the other.

A further object of the in ention is to provide a met'lr ixm of the kind \l( 'l'll r(l which in ope a n will have no tend-":icy

in tent or unduiy strain the upper and hit-h will .nrlude means tor moving any e \'('e S ot' malerial from the region or regions where it mar m'vm to the region or regions where it needed in the ope 'atioim'if shapingtbe toe and forming the out-tn 'ned flange.

In the illnst rated embodiment of the invention it will be noted that last s hz:\e been dispensed with in the toe shaping operation,

the place of the last being taken in theconstruction shown by a former, preferably of "metal so that it may be :readily heated,

which former is removed from the shaped toe as soon as the material is set in its proper form.

I twill be evident, therefore, thata further object 'of the invention is the provision of means for shaping the toe of a stitch-down upper which will avoid the necessity for lasting the upper in the usual way. An.

obvious advantage of such a mechanism is the saving effected in both lasts and lasting tacks.

All methods of lasting in the usual way with wooden lasts and tacks involve considerable -Waste of upper material which it is necessary to trim off after the upper has been lasted. This is especially true of some much material as is actually necessary to form the upper and its flange. In the construction illustrated, this inventive idea is carried out by providing means which gages the flange upon the upper, in combination with means which properly shapes the upper while it isheld by the gaging means. It is obvious that if it were attempted to shape an upper in this way by gaging the flange upon a flat blank and then rigidly confining the flange while the upper shapmg means operated upon the unconfined.

ortion of the blank, there would be great iability of tearing the material, especially if it were comparatively non-extensible mamaterial like patent leather. It is further obvious that this liability to tear 'wouldbe increased if, in'such a combination, it were attempted to bulge out the toe porton over -the flange in order to form a crease around the bottom of the toe.

A further important feature of the invention, therefore, is the provision of means for clamping the gaged flange portion of the blank to be formed or molded in such manner that portions of the flange, which, in the upper as finally shaped orvmolded,

would have an excess of material, may bemoved toward other portions, which, owing to the shape of the upper, would havea deficiency in the amount of material necess'ary for the proper operation of'the shaping means. It is obvious that such movement of the flange portions of the blank to be formed or molded will also have a tendency to gather in the material of the blank along the flange line and thus cause a fullness of material upon each slde of this line,

blank of finished material maybe clamped in such manner that clamped portions of the blank may be moved relatively to the clamp.- ing means in defined directions without scratching or tearing the finished side of the blank In the preferred construction this feature is embodied in a clamping means having a smooth clamping surface adapted to engage the finished side of the toe blank and having a roughened clan'iping surface adapted to engage the unfinished-side of the toe blank, the roughened surface being formed upon apart movable in the plane of the clamped portion of the blank whereby the said clamped portion may be, moved with the'movable part of the clamping means over the smooth clamping surface.

- At the forward end of a base or frame 2 which is adapted to be mounted upon a bench or othersuitable support is an enlargement 4 having, in the construction shown, an approximately U-shapcd recess and constituting an elevated support for a plate 6 which forms the stationary member of a clamping'device for clamping a toe blank. The platetiis smooth on its clamping face and is provided with a recess-ovcr lying that in the support 4 but somewhat smaller, so that its inner beveled edge projects over the recess in the'support 4; The recess in the plate 6 has the contour desired for the bottom edge of the toe to be formed.

A movalji'clamp member 8, adapted to cooperate with the clamp member 6, is

mounted upon rods 10 passing through" openings in the'member 6 and in the support 4 andconnected at their lower ends by a cross piece 12, from the ccnter of which extends a rod 14 to a treadlc 16 pivoted upon a support 18 which may be mounted upon the 'flo'or. By depressing the treadle 16 the clamp member 8 may be brought down into engagement with the clamp member 6, or with the blank lying upon the member 6. A toothed plate 19 adjacent to the path of the trca'dle is adapted to lock the treadle and i i 't t with it the clamp member 8 in depressed position. The clamp member 8 is provided with neth or corrugations on its under side in order that it may firmly grip the mater al of the toe blank, these teeth or corrugations in the illustrated embodiment of the invention being carried by plates mounted upon the member 8 with provision for movement relative thereto. Of these plates, those ada ted to grip the side portions of the toe or the portions of the blank which are to form the flange along the sides of the we. are indicated at 22. '12 upon the drawand are each provided with threaded pi; -l adapted to travel in slots in the clamp member and confined in said slots by nuts A third toothed plate is mounted upon the clamp member 8 in position to grip the forward part of the toe blank. this plate 30 being connected to the member .5 by. a headed screw traveling in a lot 3% in said member. It will be noted that these plates have movement only .in the plane of the clamping means,the side plates being so guided in their slots that they move in converging paths toward the front of the toe blank, and the front plate being guided in its slot and by its contact with the side plates so that it moves rearwardly with a clampedportion of the blank.

The side plates are preferably kept nor: mally in their rearmost positions by springs 36 and 38. the spring 36 being; attached at its respective ends to a pin it) on the clamp member 8 and :1 lug -12 Oil'lllt righthar-d plate 22. The spring 38 is attached to a similar pin 40 upon the clamp member 8 at its rear end but at its forward end it is attached to one arm of a lever 41, pivoted at 16 upon the clamp member 8 and having its other arm pivotallv connected with the plate 30. An otl'set portion l-S upon the lefthand side plate 23 is adapted, as the side plate 22 lllU'i'Bh forward. to engage the outer arm of 1b:- lever and cause it to rotate about its pivot. l thereby moving in a rearnard direction the front plate :ao.

Movement longitwlinaliy oi the clamping Inechanian may be impaited to the carriage it and the former so by means of the lever 60 pivotally mounted .Lll ears '2 rising from E outer edge of the toothed portion of the the base 2. The lever 60 has an enlargement about its pivot. said enlar ement being provided with circular shoulders ecerntric lo the pivot of the lever, and links (3% connected at one end to. the pivot 53 have openings at their other end into which the shoulders upon the lever (30 fit. Rotation of the lever (50 about its pivot therefore imparts longitudinal movement to the carriage 54, forward movement being imparted to the earriage when the Ieveris depressed and rearward movement when it is 'aised.

The toe former 50, when not in use, is adapted to rest upon a steam pipe (36. shown in section in Fig. 3, which steam pipe passes through the support 4: below the clamp member 6 and is adapted to lltntl the support and its attached clamp members. A depressing lever 68 pivoted at 70 in a forked post 72. integral with the support l at its forward end, carries an engaging block Tl adapted to engage and depress the toe former 50 as it rests upon the toe blank clamped between the clamp members 6 and 8. The action of the depressing lever is 01d temporary. the toe former 50 after it has been depressed sufiiciently by the depressing lever being moved forward by the lever (30 until its forward end lies under the overhanging part of the clamp plate 6 by which it is kept in its depressed position. s

The shape of the recess in the clamp plate (3 determined not only by the style of the shoe for which it molds the toe, but also by the (littering characteristics of the right and left shoes of a pair. If. therefore, a. toe is to be molded which is not symmetrical, two molding devices are preferably employed, one for the toe of a right shoe. and the other for the toe of a left shoe. of a pair. =Furthermore, it is advantageous to provide several of these molding devices for each operator, in order that the former may be allowed to remain in the toe fifte! it has shaped it until the material of the too has adapted itself to, or set, to its new form.

The operation ofthe mechanism lrereinbefore described is as followsz A suitable toe blank, such. for example. as that shown in Fig. 4. .having in position its lining and stiff material to form a box too, is clamped along its outer edge between thernunp members 6 and S. the material of the blank when clamped lying" approximatelyall in one A lldnlk' 5 plane. As the blank is placed upon the loner clamp member 6 in position to be clamped. the width of the flange to be form-- ed is gagrt-d from the inner edge of the member (3 in any suitable way, as, for example, by extending the edge of the blank to the plates 2;. 22 and 3t), and the clamp member is then-moved down to engage the inner. -side of the blank. the outer or finished side lying against. the smooth surface of the plate 6. The toe former 5t) and frame 56 2 have previously been raised above the clamp;

ing mechanism. The blank having been clamped, the toe former 5G is now brought down upon the upper surface of the blank and the depressing lever 68 is swung about portions of the clamped material along the sides of the toe blankwill cause the plates 22,22 to move forward with the toe former.

Thismoveinent of the plates 22, 22 will effector .permit the forward movement of the portions of the flange along the sides of the toe which are held by said plates, these portions moving freely over the smooth plate 6. As the left-hand plate 22 moved forward with the toe former, the engagement of its ing witlf'it the clamped between it and the plate 6. Should the plate 6, the lnncrsole being of such size offset part 48 with the lever -14; will cause the front plate 30 to move re'arwardly ca rryortion of the toe blank the side plates 22, 22 for any reason fail to move forward under the pull of the .ma-

terial, due to the action of the toe former 50,- the pushers 58 upon the front of the frame 56 will engage their rear ends and push them positively forward.

It will be noted by an inspection of Figs. 2 and 3 that the rearward movement of the front toothed plate 30 will cause some of the material clamped bv it to be moved so that it can be pulled over the edge of the platefi by the forward movement of the former and thus be used in forming the bulge at the front of the toe over the flange. It will be further noted by an inspection of Fig. 1 that the forward movement of the slide plates .22, 22 and the rearward movement of the .Th is gathering in or puckering of the material-in this region and the moving of the material held by the. front plate 30 into a position where it may be utilized in formingthe bulge facilitates the proper shaping of the toe, and tends to equalize the strain onthe different parts of the blank in the toe forming operation'and particularly assists in preventing undue strains upon any part of the clamped margin of the blank. The position of .the eccentric shoulders upon the '-ever 60 is such with respect to the pivots of the lever that when the lever is depressed to push forward the former 50, the lever holds the -f0rmer in its forwarl position until it is again actuated to withdraw the former. The former is thus held locked in i s depressed position through the action of with the under side of the plate 6.

The material of the blank is preferably tempered before it is operated upon by the mechanism hereinbcfore described, although this is 'not essential to the successful operation of the mechanism. that the heating means is so arranged that it heats the clamping means, and that it also imparts heat to the material of the toe while the toe former is locked in its depressed position during the toe forming operation. The inside of the toe blank and the adjacent sides of the toe stiffener and toe lining are preferably provided with cement, so that they are both pressed into shape and cemented together in the toe forming operation.

After the toe has been allowed to set to its new form while the former is locked in its depressed position and while the flange is held between the clamp members by the engagement of the treadle l6 .vith the plate 19, the former is withdrawn, the treadlc is released, and an innersole, provided with cement along the edge of its inner face, is laid upon the flange of the toe lying upon that its edge lies flush with the outer edge of the flange. The clamp member 8 is then depressed sufliciently to press the innersole firmly into en agement with.the out-turned flange. The formed toe with its attached innersole is then removed and the innersole and flange and further fastened together by stitches. a

the lever 60 and through its cngagcment It will be noted It is obvious that with material which maybe stretched considerably, a toe shaped like that shown in Fig. 5 may be formed with mechanism of this typeinwhich no part of the clamping surface is movable in its own plane. It is also obvious that the relative movement of the clamp and the toe former which causes the bulge of the toe over the flange may be effected in other ways, as, for example, by providing a mov-- able clamping means. The invention is not limited to the number of movable clamping plates, shown nor to the D tions of movement illustrated, nor is it limited to a construction in which the outer edge of the blank is engaged by movable plates. It is obvious that some of threadvantages ofthe construction shown might be gained in a construction in which only the frcint plate was movable and in which the side plates were stationary or vice versa.
