Specification of Letters Patent.

Patented July "2, 1914.

Original application filed March 30, 1908, Serial No. 424,225. Divided and this application filed October 27,

To all whom it may concern Be it known that I, ORRELL AsrrroN, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in theseveral figures.

This invention relates to machines for use in the manufacture of boots and shoes, particularly welt shoes, and is a division of my application Serial No. 424,225, filed March 30, 1908, which said application matured J une 25, 1912 into Patent No. 1,030,762.

In making welt shoes the upper is laid over the thinned marginal portion or feather edge of the innersole and against the shoulder or lip of the innersole and is temporarily fastened by a wire or other continuous binding material at the toe while at the sides of the shoe the upper is secured by partially driven tacks inserted through the upper into the innersole in or adjacent to the angle between the lip and the feather edge. Subsequently the upper is permanently fastened to the innersole in the inseam sewing operation by stitches which pass through the upper into the innersole, and for the purpose of obtaining and securing a tight seam it is desirable that the stitches pass through the upper into the innersole close down to the base of the li 3.

An object of this invention is to prepare the lasted shoe for the inseaming operation by creasing theupper stock snugly down into the angle between the feather and the lip of the innersole so that the stitches may pass deeply into the innersole at the base of the lip and the upper be tightly drawn by the stitches against the adjacent faces of the innersole. In addition to the advantages of the tight and secure seam gained by the use of this invention, the fact that the stitches can be located low down enables the shoe to be trimmed after the inseaming operation close to the surface of the middle portion of the sole so that the shoe requires less filling material in the middle portion of the sole than would otherwise be needed.

Serial No. 657,135.

A feature of this invention consists in the provlsion 111 a machlne for working on a lasted welt shoe, of improved means for creasing the upper into the angle between the lip and feather edge of the innersole.

- In the illustrated embodiment of the invention the creasing tool performs its work by a beating and rubbing operation, the tool being actuated to act by impact against the upper standing against the lip and to have a rubbing and pressing action upon the upper material lying upon the feather or marginal portion of the innersole from its edge to the lip. To this end the creasing tool is shown as connected to a reciprocating carrier by which it is moved in substantially the plane of the shoe bottom from and toward the lip while the shoe is held up against the of the reciprocating movements may be less than the width of the marginal portion of the shoe bottom so that the creasing tool remains in continuous contact with the shoe. The striking face of the creasing tool will preferably be shaped to engage and crowd or beat downwardly as well as inwardly the wire which binds the upper in the angle of the innersole about the toe. To this end the tool is herein shown with a beveled or inclined lower edge on its end face. This acts at each blow to wedge the wire farther downwardly and seat or embed the wire in the upper and thereby crease the upper into the angle. A further function which may be performed by the creasing tool, in addition to forcing the upper into the angle of the innersole, is that of smoothing and compacting the upper stock upon the feather of the innersole so that the welt which is laid upon this marginal portion of the shoe bottom and secured in the inseaming operation shall find a smooth surface of upper material upon which to lie and will be positioned and attached snugly with relation to the marginal portion of the inner-sole thus presenting a close and tight welt crease between the body of the shoe and the upper face of the welt in the finished product.

A further feature of this invention consists in novel combinations with a creasing tool arranged as above suggested, or otherwise, of a guide for engaging the bottom of the shoe. This guide will preferably be arranged to position the shoe both vertically and laterally with relation to the creasing tool and in the preferred construction herewith illustrated the guide forms an abutment engaging the bottom face of the innersole andthe inner face of the lip of the innersole. The guide is preferably located in position to form an abutment between which and the creasing tool the lip of the innersoleand the upstanding upper matei innersole so that these tools may act by imrial are gripped or pinched inthe reciprocation of the tool. By this means danger of though the creasing tool is not necessarily,

the creasing tool bending the lip from its upright position is obviated and instead the lip and the upper material standing against it are formed or reshaped into an 1 upright position toreceive to the, best adupstanding upper material after the shoe has been lasted and before the inseam trimvantage the operation of the inseaming machine. The creasing tool may advantageously be yieldingly actuated whereby to .provided for trimming ed the projecting edges of the vamp and lining whlle the iblocking and creasing tools are acting respectively upon .the side and bottom of the E shoe. In the machine shown as embodying the invention, these vamp trimming means accommodate itself to the difference in the thickness of the upper material and lip, commonly called the between substance, at difierent portions oft-he shoe. Preferably, and as herein shown, the shoe guide or abutment is a driven roll turning about an axis substantially perpendicular to the shoe bottom in the direction to feed or assist in feeding the shoe for the operation oft-he creasing tool progressively around the shoe. Also preferably, the roll will be provided with ribs or grooves on its periphery extending oblique to its direction of rotation and arranged to tend to lift or work up- I wardly the portion of the innersole lip with which it contacts. By these means the lip is straightened up into position to receive the inseaming operation in case the lip for any reason does not stand upright, as for example, in case the lip has not been properly turned up or has been bent or battered down in the lasting or other preceding operation. It is recognized as desirable to beat or smooth the side of the shoe at and adjacent to the edge of the shoe bottom at which portion slight wrinkles or inequalities are sometimes found after the lasting operation. This beating or smoothing operation, commonly termed blocking, is designed to take out any such inequalities and conform the contour of the shoe accurately to the contour of the side of the last at this portion.

In accordance with a further feature of this invention, meansis provided for blocking the shoe during the operation of the creasing tool. As herein illustrated, a blocking tool is mounted for movement with the creasing tool and is arranged to act upon the side of theshoe from its edge downwardly while the creasing tool acts upon the bottom of the shoe from its edge inwardly. These two tools therefore, between them, shape or form the upper to the last at and adjacent to the edge of the shoe bottom and produce a shoe having at this portion a contour of its outer surface corresponding to the shape of the under-lying faces of the last. As herein shown, the blocking tool is yieldingly attached to the carrier upon which the creasing tool is unyieldingly mounted. The stroke of the carrier will cause the blocking tool to be retracted from the side of the shoe and the creasing tool retracted from the upper standing against the lip of the contact with the shoe bottom.

It is usually desirable to trim away the ming operation. Accordingly, means are comprise a stationary knife and a cooperat- .ing reciprocating knife and, in accordance with a further feature of the inventlon, connected mechanism is provided for operating both the reciprocating knife and the carrier upon which are mounted the creasing tool and the blocking tool.

These and other features and advantages of the present invention will be fully set \forth in the following detailed description of so much of-a machine embodying the present invention as is necessary for an 1111-.

jderstanding thereof and will then be defined in the appended claims. Referrlng to the drawings: Flgure 1 1s a side View in elevation of a maclnne embody- .ing the present invention; Fig. 2 is a view similar to Fig. 1 and showing a modification; Fig. 8 1s a plan view; and Fig. 4 1s a vertical sectional detail showing the operating tools and their operative relation to the shoe being treated.

The frame of the machine supports a driving shaft 2 having an eccentricv embraced by a, strap 4, as shown in dotted lines in Figs. 1 and 2. This strap is connected to a reciprocating bar 6 that carries a knife 8 adjustably secured in position thereon by the bolt 10.v The knife 8- cooperates with a fixed knife 12 suspended by I a bracket 14 from the overhanging arm 15 of the frame and, also supported by the shaft 16 which passes through it and is provided below the knife 12 withthe feed roll 18. The shaft 16 is driven byva worm gear 20,

meshing with a worm on the shaft 22 which is driven by a belt 24 from a pulley on the shaft 2. The feed roll is provided on its periphery with ribs, as at 25, which tend to lift the vamp or lining with which they contact into position to be acted upon by the cutters. The ribbed roll also tends to feed the shoe in the direction in which the operation is progressing. The roll 18 is formed as a truncated cone having its smaller end position to contact with the insole and constitutes a rest about which the shoe maybe tipped to vary the presentation of the shoe according to the contour of the particular portion of the shoe being blocked.

The blocking tool, indicated at 60, is shown in Fig. 1 mounted upon the knife bar 6. In this construction, the bolt 10 secures upon the bar 6 a carrier 62 in which the blocking tool 60 is yieldingly mounted and arranged to slide forwardly and backwardly. The tool is held in its foremost. position by a. spring 64 pressing against a stud 65 projecting inwardly from the blocking tool 60 through a slot in the carrier 62. In this construction it will be understood the blocking tool is operative at all times when the trimmer is in use.

The carrier 62 is provided with an end portion 66 (Figs. 1, 2 and 4) adapted to project outwardly beyond the blocking tool 60 when the latter is in its backwardly pressed position and to overlie the marginal portion of the shoe bottom at such times. The reciprocating member 66 which thus forms a third tool preferably projects over the shoe bottom far enough to press the vamp against the outer face of the lip 55 of the innersole. The lip abuts on its opposite side against the feed roll 18 and the member 66 therefore serves to crease the upper material into the angle between the feather edge of the innersole and the outer face of the lip and to beat the upper against said outer face of the lip, while the roll 18 forms an abutment for the inner face of the lip. The pin 65 and slot connection (Fig. 4) limit the projection of the member 66 beyond the blocking tool 60 to sub tantially the width of the feather of the innersole. Preferably, too, the eccentric embraced by the strap 4 in the first construction (Fig. 1) and the cam 30 of the second construction (Fig. 2) are formed and arranged so to limit the backward or return movement of the member 66 that in its retracted position the member 66 is not entivelv withdrawn from engagement with the feather edge of the innersole. The resuit is that the creasing tool 66 is moved in a path corresponding substantially to but slightly less in extent than the usual width of the said feather edge so that during its operation the creasing tool remains in continuous shoe guiding contact withthe shoe. The creasing tool 66 thus acts as a height gage for the shoe, insuring by its continuous engagement with the feather edge of the shoe that it will not strike against or mar the upper at the edge of the shoe or override and thus batter or break down the lip of the innersole, as might happen if the shoe were not held by the operator at all times at the right height and angle relatively to the said tool 66. "When the vamp is bound in position by a wire 68, as is usual, the member 66, which for the purpose of identification will be called the creasing tool, serves to force or beat the wire into holding position. To this end it may be formed with an inclined face 69 to crowd the binder downwardly as well as inwardly into position to hold the upper in the angle between the lip and feather edge of the innersole. Bv forcing the wire, and thereby the upper, snugly into the angle a tighter inseam can be formed in the subsequent inseam sewing operation.

In the modified construction shown in Fig. 2, the carrier 62 upon which are mounted the blocking tool 60 and the creasing tool 66, is supported by a separate slide from that which carries the trimming knife 8, and the blocking tool 60 and the creasing tool 66 are actuated and controlled independently of the knife 8 so that, when desired, the blocking hammer 60 may remain at rest while the trimming knife 8 is reciprocated. In this construction, the shaft 2, has, in addition to the eccentric embraced by the strap 4 connected to the reciprocating knife bar 6, a cam 30 having in its side a groove 32, which at its inner edge is concentric with the shaft and at its outer edge is eccentric through a portion of its length, forming at 84 a drop leading to a concentric portion 36. Standing in this groove is roll 38 on a reciprocatory bar 40 that carries at its front end the blocking tool 60. Projecting laterally from the bar 40 through a slot in the frame is a stud 44 embraced by the slotted upright arm of an angle lever 45. This lever, which is pivoted at 46, has an opening through which extends the treadle rod 48 connected to the treadle 50. A spring 52 is interposed between the head of the rod and the upper face of the horizontal arm of the angle lever. A light spring 54 connects the rear side of the angle lever with the frame and holds this lever rocked backwardly with the roll 38 normally against the concentric inner wall of the cam groove. When the roll is in this position the blocking hammer remains at rest while the trimming knife 8 is reciprocated. By depressing the treadle 50 the roll 38 is forced against the outer Wall of the groove and as the high point 34 passes the roll the blocking hammer is actuated toward the shoe with a force dependent upon the eXtent to which the spring 52 has been compressed. By depressing the treadle and compressing the spring 52 more or less the strength of the blows of the hammer can be varied during the trimming operation and entirely independent of that operation. The treadle 50 may be depressed to start the blocking hammer either when the shoe is first inserted so that the blocking operation will begin at the point where the trimming begins or the treadle may be depressed later in the trimming operation to cause the blocking operation to begin at any desired point.

In the use of the machine the workman presents the shoe in the position shown in Fig. 1 with the face of the innersole against the lower end of the feedroll 18 and preferably with the inner face of the lip 55 against the periphery of the roll. By the reciprocation of the knife 8 the projecting edges of the vamp and lining are trimmed as shown. \Vhile the feed roll has a tendency to advance the work in the direction in which the operation is progressing the workman holding the shoe in his hands controls the rate at which the shoe is advanced and can hold the shoe stationary at any particular point while the blocking hammerthoroughly beats the upper on the side of the shoe at any places, that require special treatment. In this way wrinkles or inequalities in the side of the shoe can be quickly beaten out.

It is to be observed that the blocking hammer is formed on its outer acting face to engage the side of the shoe at and adjacent to its edge and preferably the hammer extends slightly above the edge of the shoe and also extends downwardly along the side of the shoe for some distance.
