I STITCH-DOWN-SHOE-LASTING MACHINE.

Application filed December 5, 1913.

To all w/z out it may concern Be it known that I, PAUL Tnnonon Burns, a subject of the Grand Duke of Baden, residing at Rodelhcim, Frankforton-the- Main, Germany, have invented certain Improvei'nents in Stitch-Down-Shoe-Lasting Machines, of which the following description, in connectionwith the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes and in particular to machines for lasting shoes having an extension sole edge upon which an outturned' upper flange is secured. Shoes of this type are commonly known as veldt-- schoen in some parts of Europe and in the United States are usually referred to 111s stitch-downs.

The present invention seeks to overcome certain objections which have been found to exist in machines heretofore employed for this class ofwork.

Accordingly, one important feature of the invention lies in the provision, in'a machine of the type referred to, of an improved pressing device and a support for the shoe which are so arranged that the shoe may be presented for the described operation thereon of the presser with the upper and presser in full view of the workman, the shoe lying preferably in a slightly upwardly inclined position. This enables the workman closely to observe the progress of the work and accurately to guide the shoe in present ing different portions thereof to the presser.

Another feature of importance is com prised in an improved pressing or forming device which is yieldingly support-ed for movement, and is actuated preferably in a curved path so as first to engage the shoe upper at a point located a short distance above the edge of the last, and then to press the upper downward andpush it into the angle formed by the last edge and the sole,

and thereafter to force the upper flange firmly against the surface of the extended sole edge so that it will be pressed flat there on. The contracting surfaces of the'upper flange and the sole edge or either of these parts are preferably coated with cement prlor to presenting the shoe to the machine Specification of Letters Patent.

described position having its upper presented in full view of the workman; Pref-t erably the work support is sustained yield ingly upon a spindle or the like in order that the force of the downward blows imparted by the presser maybe cushioned, and means are provided to adjust the tension of the yielding means and thus vary the amount of resistance which is offered to the action of the presser. The described work support is shaped to fit Within the channel of the shoe sole and has a beveled edgevto engage the lip. Preferably an adjustably mounted sole restis located in front of the rotatable Work support to cooperate therewith in properly supporting and positioning the shoe forthe operation thereon of the presser.

Another feature of the invention is found in a provision for sustaining the work support'for adjustment longitudinally of the machine to position it properly for sole edges of different widths, or degrees of extension. illustrated embodiment ofthe invention, a slide whichcarries the work support and is guided for movement in ways mounted upon. the work support spindle. A suitable handle is connected through appropriate devices with the slide to effect its adjusting movement-s.

Other features of the invention including important details of construction'and com binations of parts will be hereinafter more particularlydescribed and claimed. t

Figure 1 represents l a side. elevation, partly sectional, of a machine embodying the invention; Fig. 2 isa front elevation, partly in section, of the same machine;Fig. 3 is a detail view showing diagrammatically the fore part of a shoe in position for oper- This feature comprises,= in the ation thereon by the elements of the machine, and Fig. 4 is a detail. The head 1 of the machine is mounted upon a suitable pedestal, and carries bearings for the driving shaft 2. Said shaft supports a loose pulley 5 and also has rigidly secured to its outer end a clutch member 6 having a cone face to cooperate with a cone face formed interiorly of the loose pulley 5, a spring 66 normally holding said clutch parts separated. A treadle rod 4 carries a wedge which engages a wedge surface acting against the loose pulley and moves said pulley along the shaft to effect engagement of the clutch members for imparting rotation to the driving shaft when the workman steps on the treadle connected to rod 4:, while a reverse movement of the loose pulley will cause a disengagement of said members and stop the rotation of the shaft when the treadle is released.

The shaft 2 carries at its inner end a disk 7 having a crank pin to'which is joined a pitman-S having connection at'its opposite endthrough a pin 9 with a cross-head 10. The cross-head is guided for vertical reciprocating movements in the machine head'by the rods 110 which fit bores in the cross head. A bell-crank lever 12 is pivotally supported by a pin 11 on the cross-head. The bell-crank lever has vertical arms to the lower portions of which is pivoted the rear end of apresser-foot 13, having below the front end a flat surface 130,- as shown.

The bell crank 12 and presser-foot 13 are provided, respectively, with stops 131 and 132, for limiting the amount of upward yielding movement of the presser foot as it turns about the pivot 38' when operating upon a shoe upper. Intermediate its ends the presser foot is pivoted to a rod 16 which passes freely through a block having trunnion connections 36 Wlth the forward short arms of the bell-crank 12, so as to swing freely thereon, and a spring 15 is confined between the block and the presser foot. The

rod 16 has a stop nut 37 threaded thereon through-which the tension of spring 15 may be adjusted, and hence the amount of resistance offered by the spring to the upward swinging movement of, the presser-foot, controlled. i Y

The pivot 38 connecting the lever 12 with the presser-foot carries rolls 40 which run in cam- ways 14,14, formed in themachine frame on opposite sides of the presser-foot. These ways are shaped to cause a forward movement of the presser-foot during the first portion of;the downward movement which the foot receives from the cross-head 10,"and as the result of these two movements the end of the foot moves in the curved path.

indicated in Fig. 3 bya broken line. Dur-' 'ing the'remaining portion of the downward movement of thefoot the rolls 40=pass into the slightly backwardly inclined portions of the grooves 14: which cause a reverse movement of the foot. y

The frame 1 1 is provided with vertical guideways 117, 117, which receive a slide 17. This slide has a spindle 18 which passes through a sleeve 23, having threaded engage ment with the frame of the machine and carrying a set'nut to hold the sleeve in that position to which it has been moved through such engagement. The lower end of the spindle 18 is threaded and a clamp nut 19 is secured thereon and bears against the lower end of the sleeve 23. A spiral spring 2-2 is confined between a collar above the sleeve and the slide 17 and yieldingly sustains the work-supporting wheel 30 against the impactive force of the presser-foot when the latter contacts with a shoe sole on said support. The tension of the spring 22 is adjustableby means of the nut 19 on rod 18, and the height of the work-supporting devices, as an entirety, may be adjusted by moving the sleeve 23 up or down in the. frame, the sleeve being held in its different positions of adjustment by the set nut.

By adjusting the tension of the spring 22 the amount of yielding resistance offered to the blows of the resser-foot can be controlled to meet varying conditions of the stock, while the adjustments of the height of the work-supporting wheel will enable the operator to position shoes of different sizes and styles in the correct vertical relation to the presser-foot.

The slide 17 has horizontal guideways 37 within which slides a block 35 having a vertical pivot thereon to rotatively sustain a work supporting wheel or disk 30. This wheel has a beveled upper surface to fit withinthe channel of a shoe sole, and a peripheral beveled portion 32 to fit the inner surface of the channel lip as shown in Fig. 3. By this construction the sole'edge will be guided accurately through the engement of the sole with the wheel as the operator feeds the shoe along to present successive portions of the upper to the action of the presser-foot. of the wheel 30,- the sole supporting pin 31 which is adjustable in height through a set screw, as shown by dotted lines in Fig. 1',

thus coeperate with the wheel 30 in supporting the shoe in position for operation The block 35 also carries, in front thereon by thepresserfoot. Movement of the block 35 in the ways 37 to adjust the position of the work-supporting wheel .30

and pin 31. appropriately for shoes having 1 soles of difl'ercnt widths may be effected conveniently through a knob or handle 20 carrying a crank pin which is connectedby a link 21 with the block. Rotation of the handle 20 in one directionwill efiect a forper and has been fitted over the last, is presented to the lTltIClliIlGlS shown in Fig. 3, the rotatable work-supporting wheel 30th gaging beneath the sole andfitting within the channel and against the lip by its two beveled surfaces and the sole support 31 engaging the sole to the rear of the lip. Either the upper surface of the sole edge, the lower face of the upper which contacts therewith, or both of these parts, are coated with cement'prior'to assembling the shoe.

The shoe when thus positioned presents its upper portion to the workman who may thus clearly observe the progress of the work.

When the treadle' is depressed the brake will be withdrawn and the wedging surfaces on the treadle rod and loose pulley will act to-force the clutch'members into engagement to start the rotation of the driving shaft. Through the previously described connections between the shaft and cr'ossf'head 10 the latter will be reciprocated andupon each downwardmovement the presseiafoot will be caused totravel downwardly and forwardly ina curved path, its forward end,

meeting the shoe upper at a point above the edge of the last and pressing it downward and snugly into the angle formed by the extended portion ofthe soleiandthe last. During this movement the foot will yield backward slightly under the influence of the spring 15, Finally by a further downward movement the presser-"foot will press the upper fiat upon the extended edge of the sole. This operation is repeated rapidly and the workman moves the shoe along to present successive portions of the upper to thepresser-foot, the work supporting wheel turning about its axis asthe shoe is thus fed'and servingto support the shoe, while guiding it and maintaining the sole edge at all points the same distance fromithe presser-foot. The sole support 31 also acts in conjunctionwith the wheel to properly support the shoe asthe shoe is fed along by the workman. As the sole'flange is pressed fiat upon the-upper face of the sole the cement on the contacting surfaces of these parts will cause them to adhere andthus,

without the aid of tacks, will hold the upper in substantially the position *to which it has been forced by the resser-foot. By reason ofthe fact that the tool moves in a curved path over the shoe edge suchmovement will serve to stretch the upper and mold to the shape of the last, and as the point of the tool enters the crease formed at the point where the sole and last meet the'upper will be forced into the crease and a sharp angle formed thereby with the upper flange that overlies the sole. It'will also be seen that the flange of the upper will be pressed against the sole in a very effective manner by the fiat portion 130 of the presser so as to adhereto, the sole throughout every por- 7 tion of its contacting surface.
