(01. 12 123) This invention relates to lastingmachi'nes,. and more particularly to machines for lasting end portions of shoes. The invention i hereinshown as. embodied in means for lasting the toe ends of shoes, for which use such means isespecially well adapted, but in some aspects the inventionis also applicable toheel-end lasting,

In lastingthe toe ends of shoes it: is the eonmon' practice to use a pair of wipers which are shaped to conform-to the contour'of theedge at a lastbottom pattern corresponding to a shoe- 0f a given style and size. Although thi has been regarded as the most satisfactory manner of shaping such wipers, it will be evident thatin operating on a; shoe of that style and size the wipers, because of the added thickness of the upper materials, will notcontorm exactly to the contour of the upper opposite the edge face of the insole and in the case of a Goodyear welt shoe will not conform exactly to the contour of the'upstanding margin of the upperpressed i'nwardly against the usual-lip or shoulder onthe insole: at some distancefrom its edger l-n the wiping of the upper heightwise-of the last, moreover, commonly known: as the upwiping operation, the approach to conformity otthe wipers to the contour of the upperaround the toe end of. the lastwill'vary atdifferent distances from the'edge of the-insole.

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

In the drawings,

Fig. 2 is a section on the line IIII of Fig. 1, showing the relation of the wiper to a shoe of the Goodyear welt type substantially at the beginning of the upwiping operation;

Figs. 3 and 4 are views similar to Fig. 2 showing the relation of the wiper to the shoe at the end of the upwiping operation and at the end of the operation of wiping the marginal portion of the upper inwardly over the insole respectively;

Fig. 5 is a view similar to a portion of Fig. 1, but showing an alternative form of wiper;

Fig. 6 is a section similar to Fig. 2 on the line VIVI of Fig. 5;

Fig. 7 is a view corresponding to Fig. 4' but showing the alternative wiper; and

Fig. 8 shows a portion of the alternative wiper in plan as it appears at a certain stage in its manufacture.

The invention is herein shown, for purposes of illustration, as embodied in means adapted for use in a modification of a bed-lasting machine of the type disclosed in United States Letters Patent No. 1,018,477, granted on February 27, 1912, on an application of Matthias Brocks. A machine of that type includes a toe wiper support which may be adjusted in various Ways relatively to a shoe positioned bottom upward in the machine and which carries a pair of toe-embracing wipers, the support being moved upwardly by a treadle to cause the wipers, which are held against the upper by a hand lever, to wipe the upper heightwise of the last, i. e., to perform the upwiping operation. By the same treadle, after the wipers have been operated by the hand lever to wipe the marginal portion of the upper inwardly over the insole, they are forced downwardly t increase their pressure on the upper over the insole.

" The present invention provides, in place of such a pair of toe-embracing wipers, a flexible wiper constructed and arranged to extend continuously around the toe end of the shoe and to conform itself to the contour of the shoe throughout the toe-lasting operation. This wiper and the means for operating it to press the upper around the toe against the last and to wipe its marginal portion inwardly over the insole are supported as hereinafter described by a plate 2 which, it will be understood, may be secured in any suitable manner to the toe wiper support of a machine of the above-mentioned type. at 4 in Figs. 1 to 4 inclusive comprises a coil spring made of a'strip of resiliently flexible material, Ipreferably metal, which is rectangular in cross The form of wiper shown section. In order that such a flexible wiper may be so controlled as to render it properly efiective the upwiping operation and in pressing the up- ,per downwardly on the insole, it is so formed as to extend a substantial distance outwardly from the shoe and its outer portion is engaged by and confined between upper and lower portions 6 :and 8 of a wiper-supporting member l0 which is "formed to extend around the toe and is secured 4 0n the upper ends of a pair of vertical studs l2 fast on the plate 2. The strip of material of which the wiper 4 is made is so formed that the outer portion of the wiper confined as above described is rectangular in planes intersecting it transversely of the edge of the shoe bottom and has flat upper and lower faces engaged by the portions 6 and 8 of the support, as shown in Figs. 2, 3 and 4, while its inner portion next to the shoe forms an acute angle in such planes to provide a wipin edge 14 for engagement with the upper. With thewiper curved to embrace the toe as shown in Fig. 1, its wiping edge is practically continuous all around the toe.

To apply the wiper 4 to the upper preparatory to the upwiping'operation and to operate it for wiping the marginal portion of the upper inwardly over the insole it is moved bodily lengthwise of the shoe in sliding engagement with its support 10 and is also flexed widthwise of the shoe. For this purpose there is provided a flexible metal cable [6 extending through the wiper around the toe end of the shoe and secured at its opposite ends to blocks l8 which are pivotally mounted on studs 2!] carried by arms 22 extending generally lengthwise of the shoe. These arms are pivotally mounted on studs 24 for swinging movements widthwise of the shoe, the studs being mounted on the outer ends of other arms 26 which extend widthwise of the shoe and are both pivotally mounted at their inner ends on a vertical stud 28 carried by an operating bar 30 which is slidingly movable lengthwise of the shoe along guideways 32 on upwardly extending portions of the plate 2, the bar extending through an opening in the wiper support I0. Secured to a lug 34 on the bar 30 is a leaf spring 36 the opposite end portions of which bear against the arms 2% to control them with respect to swinging movements about the stud 28, the spring holding the arms normally in positions determined by the engagement of pins 38 on the arms with a crossbar 49 mounted in the stud 28. For moving the bar 39 lengthwise of the shoe there is provided a hand lever 42 pivotally mounted on a stud M on t e Plate 2 and having therein a slot 45 in which is slidingly mounted a block 48, the block being provided with a stud 50 mounted to turn'in the bar 33. It will thus be evident that as the bar 30 is moved toward the shoe it carries th arms 26 and 22 bodily with it and thus moves the wiper 4 as a whole in the same direction to apply it to the shoe prior to the upwiping operation and later to wipe the marginal portion of the upper inwardly over the insole. When the resistance of the shoe to the bodily movement of either of the arms 22 and of the corresponding arm 25 becomes great enough the portion of the spring 36 which controls those arms will yield independently of the portion thereof which controls the other arms 22 and 26 in response to continued movement of the bar 30. Provision is thus afforded, regardless of the shape of the shoe, for applying to both ends of the cable lfi'the force required for the best results in the toe-lasting operation.

The swinging movements of "the arms 22 about 'the studs 24 to flex the wiper as required widthwise of the shoe are'effected in response to their bodily movements lengthwise of the shoe. For

same stud 24 and having thereon a roll 54 engaged by a cam 55 fast on the plate 2. A spring '58 connected to the two arms 52 holds the rolls at all times against the cams. Between each arm in of the upper in 22 and the arm 52. associated therewith is a compression spring 60 through which the arm 22 is swung by the arm 52 as the latter is swung by the corresponding cam 56.. It will be evident that either spring 60 is yieldabl'e independently of the other in response to resistance of the shoe to the swinging movement of the corresponding arm 22.

When the hand lever 42 is retracted the arms 52 are swung toward each other by the spring 58 as permitted by the cams 56, and shoulders 62 on these arms engage shoulders 64 on the arms 22 to swing the latter away from the shoe and thus to permit the portions of the resilient wiper at the sides of the toe to spring outwardly. At the'same time the arms 22 are retracted bodily lengthwise of the shoe by the bar 30. To assist in retracting the wiper bodily in the same direction the bar 30 is provided at its inner end with projections 66 which extend inwardly between convolutions of the wiper and engage the inner surfaces'of two of these convolutions.

From the foregoing description it will be understood that in the toe-lasting operation the last- I ing mechanism shown in Fig. 1 is moved upwardly to cause the wiper 4 to perform the upwiping operation by use of the treadle provided for this purpose in a machine of the type to which the invention is shown as applied. The wiper 4 is thus moved from the position illustrated in Fig. 2 to that illustrated in Fig. 3. During this operation the operator, through the hand lever 42, holds the wiper pressed inwardly against the upper, the wiper conforming itself at all times to the contour of the shoe however the contour may vary at different distances from the edge of the shoe bottom. The operator may, as customary, repeat the upwiping operation one or more times while using hand pincers to adjust and control the margin of the upper. Thereafter he further operates the wiper by the hand lever to wipe the marginal portion of the upper inwardly over the insole and, if the shoe is one of the Goodyear welt type as shown, to press a portion of the marupstanding position against a lip a. on the insole as illustrated in Fig. 4, the wiper further conforming itself to the contour of the portion of the upper thus pressed against the lip. By use of the treadle the wiper is then forced downwardly to increase its pressure on the portion of the upper between it and the feather of the insole. It will be evident. that, despite its flexibility, the wiper is. held sufficiently rigid heightwise of the shoeby the portions 6 and 8 .of its support 10 both in the upwiping operation and in the pressing of the upper down on the insole.

In Figs. 5, 6 and 7 is shown an alternative form of wiper '68 which may be used instead of the wiper 4 shown in Fig. l. The wiper 68 is made of an elongated hollow member 10 (Fig. 8) of resiliently flexible material, this member being angular in cross section and being provided with a series of slits "extending part way through it crosswise thereof to increase its flexibility. The outer portion of the wiper 6B, confined between the portions 6 and B of the support it similarly to the corresponding portion of the wiper 4 of Fig. 1, thus comprises a series of segments 74 spaced from one another and rectangular in planes transverse to the edge of the shoe bottom. The inner portion of the wiper comprises an inclined strip 16 which is continuous all around the toe and forms an acute angle with the lower portion of. each segment 14 to provide a wiping edge 18 for engagement with the upper. Theopposite ends of the wiper 68 are connectedtotlie arms 22 by studs 80. Accordingly these arms are directly effective to flex the wiper inwardly and to retract it widthwise of the shoe and they also serve in combination with the projections 66 on the bar 30, which engage two of the segments 14, to retract it lengthwise of the shoe. In other respects the manner of operation of the wiper 68 is thesame as that of the wiper 4 shown in Fig. 1.
