MACHINE FOR LAYlNG SOLE-EDGES.

SPECIFICATION forming part of Letters Patent No. 478,299, dated July 5, 1892.

Application filed November 16, 1391i. Serial No. 411.997 (No model.)

To all whom, it may concern,.-

Be it known that I, EDWARD lC. WooDARD, of Brockton, in the county of Plymouth and State of Massachusetts, haveinvented certain new and useful Improvements in Means for Laying Feather-Edges of Inner Soles, of which the following is a specification.

This invention has reference to machines for manufacturing welted boots or shoes. It is well known that the inner sole of a welted boot or shoe is beveled or tapered, so that its margin presents a feather-edge bearing against the inner surface of the upper. The pressure of the upper against this thin featheredge causes it to curl upwardly, and thus fail to give the upper a well-defined shape at the edge of the inner sole.

My invention has for its object to enable the feather-edge to be attened or bent downwardly into the plane of the main'upper surface of the inner sole, at the same time creasing or sharply folding the upper over the edge of the inner sole to give the u pper a well-deiined shape close to the point Where it is attached to the welt.

To this end my invention consists in the construction and combination of parts, as hereinafter described and claimed.

Of the accompanying drawings, forming part of this specification, Figure l represents a side elevation, partly in section, of a machine embodying my invention. Fig. 2 represents a top View of a portion of the machine, both of said iigures showinga boot or shoe as presented to the machine. Fig. 3 represents an end elevation of a portion of the machine.

The same letters of reference indicate the same parts in all the figures.

In the drawings, arepresentsa supportingframe, which may be of any suitable form, and is adapted to be secured to a base or support, such as a bench or table. Journaled in a bearing a. on the upper portion of the frame a is a shaft b, to one end of which is affixed a roll c, preferably made of steel, having a smoothly-'polished periphery, which is made cylindrical, or substantially so, from the inner end of the roll partly to its outer end, and is then curved or rounded inwardly to meet the outer end of the roll, this form of the roll preventing the formation of an angle upon any part of the roll, which exerts pressure upon the upper d of a boot or shoe, as shown in Fig. 1, in which the boot or shoe is shown in section.

e represents a roll, which is mounted to rotate loosely upon a stud or journal e', affixed to a slide e2, which is adapted to move vertically between guides e3 e3, affixed to the supporting-frame. The roll e is located below the steel roll c, and its periphery is composed of a sleeve or sheath e4, of rubber or other suitable yielding material.

The object of the roll e is to support the tread-surface of the outer sole d of the boot or shoe at a point below the roll c and exert an upward pressure, which causes the roll c to atten the feather-edge of the inner sole d2. The roll e is adapted to be pressed upwardly to exert the desired kdegree of pressure of the innersole and upper against the roll cby means of a treadle or other suitable device, (not shown,) which acts through a rod e5, connected with'the slide e2 to raise the roll eand exert any pressure of the inner sole and upper against the rolll c that the operator may desire. The yielding periphery'of the roll e prevents defacement of the tread-surface of the outer sole during the operation. The periphery of the roll e is preferably tapered, its larger end being coincident withthe larger end of the roll c. This form of the roll e causes the "maximum pressure to be exerted upon the edge of the inner sole and the part of the upper that bears uponsaid edge, the pressure decreasing from saidtedge toward the central portion of the inner sole, as will' be seen by lreference to Fig. l.

f represents a roll mounted to rotate loosely upon a stud f', which is supported by a slide f2, connected to the supporting-frame by a screw or bolt fpassing through a slot f 4 in said slide. The roll f has a yielding periphery, composed of rubber or other suitable material, and it is arranged to bear upon theedge of the outer sole d', as shown in Fig. 1, said roll forming a yielding-surfaced rolling gage, which determines the position of-the edge of the inner sole, with reference to the inner end of the roll c and permitsthe boot or shoe to be moved easily along by the operator during the progressive rolling of the ICO upper and inner sole, the yielding surface of the roll f preventing injury to or defacement of the edge of the outer sole. The slide f2 is rendered adjustable by the slot #and boltf, so that the roll f can be adjusted to accommodate the width of the projecting portion of the outer sole. In some boots and shoes the outer sole projects farther from the outside edge of the inner sole than in others, and as it is desirable that the edge of the inner sole be presented to the roll c at a point near the inner end of the latter it follows that the adjustability of the roll f, which permits the edge of the outer sole to extend, it necessary, inside of the inner end of the roll 0, is a very desirable feature.

The roll c is rotated by power applied in any suitable way, the power-applying means being here shown as a shaft t', rotated by a drivingbelt running on a pulley fi', the pinion i2 on said shaft and the gearing il on the shaft b meshing with the pinion 2.2.

In the operation of the machine above described the operator, holding the boot or shoe in his hands, as indicated in Fig. 2, interposes the same between the rolls c and e, as shown in Fig. l, the roll e being depressed by the operators foot to permit the insertion o one edge of the boot or shoe. The operator then, exerting the desired pressure on the roll e, moves the boot or shoe along until all parts ot the edge ot the inner sole have been subjected to the action of the roll c. It will be seen that by thus applying a progressive rolling pressure to the inner sole and upper, the feather-edge of the inner sole is laid or fiattened down and the upper folded or bent sharply over the edge of the inner sole without the possibility of indenting or det'aeing the upper. During the operation the operator pulls the upper over to bring it to a sufficiently-close bearing on the edge ot' the inner sole, so that the fold formed in the upper by the rolling action is inevitably parallel with the edge 01": the inner sole.

I claiml. The combination of a smooth-surfaced roll of rigid material, a yielding surfaced pressure-roll movable toward and from the rigid roll and adapted to bear on the bottom ot the outer sole of a boot or shoe interposed between the rolls, the axes ot' the said rolls being parallel, and a yielding-surfaced gageroll adapted to bear on the edge of the outer sole, as set forth.

2. The combination ot a smooth-surfaced roll of rigid material, a yielding surfaced pressure-roll movable toward and from the rigid roll and having its axis parallel with that of the first-mentioned roll, a yielding-surfaced gage-roll adjustable toward and from the inner ends of said rolls, and means for securing the gage-roll at any position to which it may be adjusted, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 5th day of November, A. D. 1891.

EDXVARD VVOODARD.
