11 Claims.

This invention relates to machines for forming and pressing the uppers of shoes.

As the forming and pressing has heretofore been performed, it has been usual practice to pull the shoe tongues out from between the pressing members so that these tongues are not treated during the pressing operation. Should they be left in position, undesirable imprints thereon of the eyelets and eyelet stays would result with machines as heretofore constructed.

An object of the present invention is to provide means by which the tongue, as well as other portions of the shoeupper, may be formed and pressed during the one operation and without producing the undesirable impression of the eyelets or other parts on the tongue. rlhis is accomplished, in accordance with the present invention, by interposing between the tongue and the eyelet stays a member which presents a smooth contour to the tongue, and which through the pressure imparted during the pressing operation on the other shoe upper portions, will also apply smoothing and setting pressure to the tongue, and, if desired, will crease the tongue longitudinally centrally.

Another object is to provide means facilitating the placing of the shoe With its tongue beneath the tongue-engaging member, or causing the tongue-engaging member to be introduced into operative position and withdrawn after the pressing and setting operation.

For a complete understanding of this invention, reference may be had to the accompanying drawings in which Figures l, 2 and 3 are fragmentary front and side elevational views and a top plan View, respectively, of a shoe forming and pressing machine provided with a tongue-engaging and pressingelement and embodying the invention.

Referring rst to Figures l to 5, and more particularly to Figures l, 2 and 3, a shoe pressing and forming machine of the type shown in the Dodge Patent No. 2,211,954,` granted August 13, 194), for Method of and Apparatus for Treating Shoe Uppers, is illustrated, this machine comprising a gooseneck portion l rising from a support 2, this gooseneck portion supporting at its forward and upper end an inner rigid shoe pressing form 3. This inner shoe pressing form has convex side faces Il merging in a central downwardly inclined apex 5, which vis located substantially in the central plane of a shoe shown in dotted lines in Figure 2 at '6, placed thereover. The upper of. such a shoe may be pressed against the vside faces Il, as by a pair of outer pressing" members l, each carried `at the upper end of a lever 8. These levers 8 are fulcrumed at 9 to the support 2 on either side of the shoe form and may be brought into pressing engagement with the shoe on the form by any suitable means such as that shown in the Dodge Patent No. 2,211,054, to which reference has been made.

Heretofore when pressing a shoe on such a form, it has been customary to remove the tongue Y of the shoe from its position in order that the pressing oper-ation might not press' the eyelet stays of the shoe against the tonguev and mark the tongue by reason of the varying thickness of the'eyelet stay or by `reason of the eyelets set therein.

In accordance with the present invention, a sheet material member It, which may well be of metal and of sumcient thickness and stiffness to prevent pressure of the eyelets and stays thereon from transmitting impressions to the tongue, and which is bent centrally toform a longitudinal apex Il with side wings l2 extending laterally therefrom, is interposed between the tongue l5 of the shoe, shown best in Figures 4, 5 and 6, and the eyelet stay portions i6, which for clarity are shown in Figure 6 as turned back to expose the tongue. Ihe side wings I2 of this sheet material member are arranged substantially parallel to the side walls 4 of the shoe support form and they prevent contact between the eyelet stays and the tongue during the pressing operation, which presses the eyelet stay portions against the meinber I0, the member it against the tongue i5, and the tongue l5,.as ywellas the other parts of the shoe upper, against the form 3. Certain of the pressing members, as, for example, the form .3 may be heated as by the use of electrical heating units as is well known in theart.

For the purpose of facilitating the introduction and removal of the member libetweeniand'from pressing position, it is shown'in thesefigures as carried by a rod 2G, one end of which is secured to the rear end of the member l and which extends substantially perpendicular 1toits l.apex llrvi This rod is slidable through a pin 2 l .rockably carried between the jaws k22 of a lever 23, which may be fulcrumed as at 24 to the gooseneck portion to'swing substantially inthe centralplane of the shoe form 3. As shown best in 4Figure 3, thislever 2-3 is bifurcated so as toprovidea pair of ,spaced vhub portions '25 bearing on opposite sides of the central web 26 of the gooseneck porof the rod', this rod may be -pulied forwardly and the forward end of the lever i'moveddownwardly toward the `dotted line position of Figure 2, and the member VIt) passed edgewise in between the eyelet stay portions le and the'tongu'ei Ifrom which position it maybe moved down iinto V*close engagement with the tongue 'i5 as Vshown in Figures Lland 5. Coil springs 132 .surrounding Vthe rod' and bearing on Vopposite faces of vthe pin 2l normally 'tend to. center 'this rod'with relation to the 4pin 21, but `permit the Vmember lit, -by

manipulation of 'the handle AvSi) by the operator, to be Vpositioned vas shown in Figures '4 Aand 5, preparatory to -a shoepressing operation. VThe member i5 is then `held Vvin this lowered position as by a spring llatch 33 carried bythe 'lever 213 engaging 'beneath an inclined latch plate carried by the Vgooseneclr :26 as best vshown -in Figure 11. VThis latch hasa'portion es provided with `a'lateralrecess'housing a downwardly spring pressed pin 35 whichnormally lies'in'thepath of motion of a finger v3E carried by one of the outer pressing members "i. VlThis linger 36 has 'an 1nolined'face 37 which engages and'retracts the vpin 35 when the outer pressing members l are brought inwardly into shoe pressing position, 'but after ypressing has been effected `and -the outer pressing members l are moved outwardlyytne finger -36 engages against vthe inner face 'of the pin 35 and retracts the latch S3 from the Alatch plate Se which permits the springs 25a' yto lift the member it away from the shoe, whereupon the pressed shoe may be removed readily from the inner form. In the Vretracted-or lifted position the member i@ is entirely vaway `f'romfashoejon the form so that it offers no Aobstruction to the placing or removal of the shoe. -The-possibility of a shoe Yor its tongue being improperly positioned whenthe pressing actionis effectedis'thus minimized.

In .some cases land with `some .shoe materials,

Pil

particularly where the shoe tongue is of some stiffness, a simple construction and mounting of the member l0 for the pressing operation may be employed. As shown for example, in Figures 7 and 8, the sheet material member ma may be provided with `a rearwardly projecting resilient portionli which -maykbe directly secured as by screws 4| to the forward face of the base portion Aft2 of the inside form 3 in such a manner that the member la is normally spaced from the side lwallsfll oftheformby an amount amply sufcient tol-permit ,the insertion of the tongue therebetween'wh'en the-shoe'is placed uponthe forni 3.

LDuring ,suchplaceinent the eyelet stay portions are removedsuiciently by the operator to permit them to pass over the outer face of the member |10 so'thatwhen'lthe shoe is nally positioned on vthe form, the member lila will lie between the outer face of the tongue and the inner faces l of theeyelet stays substantially in the sameposition asthe member 'l in Figures'and During the single y.pressing operation the `side Jaws press 'the eyelet stays against the member ma andthemember i'a against the tongue'and kthe tongue ,against "the inner form, theresilientjportioniyieldinginwardly. vAfterthe pressingoperation "has beengper'formed, the shoe 'may Athen be removed. vfrom "the 'form ,by `merely 'pulling it forwardly off therefrom.

VIn. Figures 9 and Ll() 'a-furtherfmodification -is shown in which the member wb is imountedtfoi' motion from and to operative 4relation with lthe insidepresser formt-b. Theinside presser form 3b 'is shown as supported on :a horizontal @bar le supported Ain "the 'upper end lof the -arm 'et upstanding from '.the 'bracket ""'li tto 'which the side presser carrying arms "8 are pivote'd. 'The arm i6 carries on 'its 'upper end a bracket )iithrough which 'is slida'b'ly mounted `in a 'downwardly vand 'forwardly direction, a -bar t9 tothe forward 'end of -which "is Ysecured 'a bar 5t ipre'ferably lflexible, `the .forward 'end of which, in turn, is secured tto the rear -end of the 'member I 3b. This member is normally held 'retracted from operativerposition, as by "a "coil l.spring kdi surrounding 'the "bar 59, and vreacting "between the bracket H38 y'and 'a Ehead 52 Aat the Arear end of 'the 'bar *49. 'This head.52 carries a 'cam follower roll 53 upon which `may bear "the upper end of an 'actuating lever i. -vThis 4actuating lever 55% is fulcrumed at 5.5 on'afirearward eX- tension ofthe bracket 137,. LOn'its Alower Yend it is provided with a camface 56 'upon 'whichbears a cam follower roll 51 at therear 'end of-an acv tuatinglever'. Thisfactuating lever ,58 is :ful-

crumed at n59 on the support flr'l and "forwardly of its lfulcrum it is vconnected through a 'link 6i) with the :lower end Aof `a vertically r`slidable bar 61 connected "through jpivoted toggle 'links 2 tothe lower end vof the arms '8. By pressing downwardly yon a han'dle 63 :at 'the forward end of the 'lever 58, the rear end of this lever "is lifted, which `ants 'to l press .the "lower Vend of the lever 5'4 rearwardly, rocking this fleverin'to the dotted lineposition shown jin `Figure'i), andorcing the Arod i8 forwardly `to v`bring the member Ib edgewise into the operative position shown in Figure '1:0 with its member 'IED positioned above 'the Yshoe 'tongue :l5 and .beneath the eyelet stays 'which are, however, Ynot .shown .in 'this figure. vFurther ldownward motion o'f the handle 63 after 'taking up lost motion of the Apin 54 inthe slot '65 of the bar 'il Iacts 'to make (the toggle of links `52 and "bring the side presser `members 1 inwardly to 'press the Vshoe against the `form with the eyelet stays pressed against the member lb, the member lilo pressed against the shoe tongue, and the shoe tongue pressed against the inside form. On lifting the handle 63, the reverse operation takesplace, the side presser members rst being retracted, followed by retraction of the member lllb, after which the pressed shoe may be moved from the inside presser form and a shoe to be pressed placed thereon for a succeeding pressing oper ation.

The action of any of the machines shown in this application is to thin and turn inwardly the topedge 'portions of the shoe, shrinking the lining and pressing the edges of the outer thereover, and to perform the same operation on the eyelet stay portions and on the tongue, and to crease the tongue centrally longitudinally, all in a single operation.
