INSOLE-MACHINE.

Application filed March 12, 19 17.

1 b aZZ whom it may concern:

Be it known that I, FREDERICK H FERR a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Insole-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for operating on soles and more particularly to the performance of certain operations upon insoles.

In the manufacture of certain types ofinsoles it is desirable to perform an operation- The present invention-relates to machines of the type and for the purposes just set forth, and one object of the invention is to produce a machine of simple construction and compact form, and particularly a machine in which the actuating mechanisms are of a simple and direct character and are located for the most part, below and in the rear of the work-support upon which the insole rests during the operation thereon.

Another object of the invention, relating particularly to its use in connection with reinforced soles, is to provide simple and effective means for trimming the reinforcing material. In order to prevent the reinforcing material on a Gem insole from being visible in the finished shoe, it is desirable to trim the material, particularly at the shank-portion of the insole, to a line on the feather within the edge of the insole. In

Specification of Letters Patent.

Such w Patented Nov. 19, 1918.

Serial No. 154,187.

the machine of the present invention it is proposed to employ reciprocating work-en: gaging members for feeding the Work intermittently, and to provide a trimming cutter for the reinforcing material which is so mounted as to reciprocate With the feeding instrumentalities. From this arrangement it results that the cutter moves with the work during the feeding movement, while its operation is performed during the return movement of the feeding instrumentalities and while the work is held stationary by means provided for that purpose- Consequently, although the cutter operates with a dragging action, it does not impede the intermittent feeding movement, since its operation is timed to alternate with the feeding movement.

Other objects of the invention, the advantages of which will be readily recognized by those skilled in the art, will be set forth in connection with the description of the preferred embodiment of the invention.

To the accomplishment of the above objects the invention comprises the features and combination of parts hereinafter described and defined in the appended claims.

The preferred embodiment of the invention is illustratedin the accompanying drawings in which Figure 1 is a side elevation,

, partly in vertical section; Fig. 2 is a partial side elevation showing certain of the operative instrumentalities in a position other than that shown in Fig. 1; Fig. 3 is a plan view of the machine; and Fig. 4 is a detail view, in section, on the line 4:& of Fig. l.

The invention is illustrated as embodied in a machine adapted particularly for ribtightening or perfecting reinforced insoles of the Gem type, theperfecting operation herein consisting in. pressing the reinforcing material. usually canvas or duck, firmly into the angles between the rib and thebody and feather of the insole, and in bending the rib to, and setting it in, an inwardly inclined position.

As shown in Figs. 1 and 3, the insole upon which the machine operates comprises the usual body-portion 6, having a rib produced by an integral upturned lip 8 and a marginal feather 10. This insole is rein forced by canvas 12, which is connected in place and extends over the 11p and the adjacent surfaces of the body and the feather,

The instrumentalities of the machine 1nclude a work-support 14:, 1n the form of a disk, with av horizontal flat surface uponwhich the insole rests. This disk is fixed on the upper end of a stem 16 which slides vertically, and rotates, in a stationary sleeve 18. This sleeve is integral with a housingmember 20, which serves as a frame and also aninclosurefor the actuating mechanism of the machine, being mounted at the upper end of a column'22 of convenient form and height.

The work support is pressed upwardly by a spring 24 which is coiled within the sleeve 18 and around a rod 26. The rod is concentric with, and fixed to, the stem 16, and it slides through a centrally perforated stop-screw 30 which is threaded into the sleeve 18. The rod is provided with adjustable stop-nuts 28 which cooperate with the screw '30 to limit the upward movement of the work-support under the influence of the spring,when no work is in the machine. To facilitate the introduction of an insole the rod 26 may be connected with operating means such-as a treadle (not shown) by which the work-support may be depressed in the usual manner.

The lip-forming tools comprise a member 32 which engages theinner surface of the lip and acts as an anvil, and a member 34 which engages the outer surface of the lip and acts as a hammer by which the lip is bent and compressed against the anvil. It will be observed from Fig. 2 that when the lip is pressed between the lip engaging faces of the two tools 82 and 36 it is bent to an inwardly-inclined position the pressure extending from the base to the crown and being suflicient to set the lip in this position.

For the purpose of trimming the margin of the reinforcing canvas 12 the machine is provided with a knife 36.

The anvil 32 and the hammer 84 are employed as means for feeding the work inter mittently, and for this purpose they are so mounted as to swing about a vertical axis in the rear of the work-support. A] :ar riage 38 is mounted within an upper housing-member 4-2 which is removably fixed upon the lower housing-member 20. The carriage is provided with a horizontal circular flange 40 which rests upon the upper surface of the housing-member 20 and fits in a correspondingly formed opening in the member 42, so that a bearing is provided on which the carriage may be oscillated about the axis of the flange 40. The carriage is held down against the bearing just described by engagement with the upper part of the housing-member 42. as shown in dotted lines in Fig. 1', and'it is'centercd. at.

its upper end, by means of a pivot-stud 44 fixed in the houslng and entering a recess in the top of the carriage.

The hammer is mounted upon a slide 46 which moves in a circularly curved guideway 47 formed in the carriage 38'. The center of the curvature of this guideway is located below, and slightly in the rear of, the Work-support, so that when the hammer is actuated by the movement of the slide in the guideway its operative extremity moves toward and from the lip of the insole in a path which is slightly inclined in a forward and downward direction. When the carriage is oscillated about its vertical axis the hammer is reciproc-ated, through a short arc, about such axis for the purpose of imparting a feed-movement to the insole through the engagement of the hammer with the lip of the insole. In order that it may participate in the same function. the anvil is mounted in a forward projection from the carriage, as will be described.

For the purpose of actuating the slide 46 and the hammer, the lower end of the slide is connected, by a ball-and-socket joint 48. with an eccentric-strap 50- which embraces an eccentric 52. This eccentric isactuatedby a power-shaft 53, and theshaft is journaled in bearings in the lower housingmember 20, and provided with a pulley 56 through which it may be connected with any suitable source of power. By these means a constant and rapid reciprocation of slight amplitude is imparted to the slide and the hammer, causing the latter to move into and out of engagement withthe lip of the insole. In order to provide for operating upon insoles having lips of ditfercnt thicknesses, the hammer is adjustahly connected with the slide by means of a bindingscrew 58, which is threaded in. the slide and passes through an elongated opening inv the shank of the hammer, and this shank is seated in a close-fitting recess in the slide.

this recess being concentric with the slide so as to limit the adjusting movement to a circularly-curved slide.

The lip-forming tool 32 has a cylindrical shank 60 which slides vertically in a sleeve 62, and this sleeve is integral with a forvward projection from the carriage so that the oscillating movements of the latter cause the tool 32, to participate in the workfeeding movement of the hammer. The tool 32 is supported rigidly. by the sleeve against the pressure due to the impact of the hammer, but by vertical moirment of the shank in. the sleeve the tool is permitted to accommodate itself to insoles of various thicknesses. v

During the lip-forming and feeding op erations the tool 32 is forced downwardly against the .work by spring pressure, as

path concentric with the shown in Fig. 1. For this purpose a leaf spring 64: is employed, this spring being articulated, at its forward end, to the shank 60, while its rear end is fixed to a lever 66 which is mounted on a pivot 68 on the car-- me e.

uring the idle return movement of the tools following each feed movement the pres sure of the tool 32 against the insole, as shown in Fig. 2, pose the lever 66 is connected, by a link 70, with a pivot-screw 72 on the slide 46. so that at each retractinzr movement of the slide and the hammer the ever is rocked in a direction to release the tension of the Spring 64. In order to insure the entire release of the pressure of the tool against the insole the lever is provided with a forwardly-extending arm 74 of which the end comes into engagement with the lower surface of the spring when the lever is moved to its extreme position, and thus, through the intermediation of the spring, the tool 32 is lifted a short distance clear of the work. This distance is, or may be, so slight, however, as not to be distinguishable in the drawings, a lift of a small part of an inch being suflicient to in surethe release of the Work from comp-ression.

When the hammer is retracted and the anvil is raised, as just described, it is necessary to prevent the insole from being forced upwardly by the spring 24 of the work support. and also to retain theinsole securely in position during the return movement of the tools. For this purpose a presser-foot 76 is employed. This presser-foot is pivoted. by a stud 7 8, on a bracket 80 which is fixed in stationary position on the housing. Integral with the presser-foot is a depending arm 82 which carries a roller 84;. The roller cooperates with a cam 86 fixed on the powershaft and is maintained in engagement therewith by a spring 88 attached to the arm 82. The cam is formed to permit the spring to swing the arm rearwardly, and thus depress the presser-foot to operative engagement with the feather of the insole. at the completion of each lipforming and feeding operation. and the presser-foot remains so depressed until the lip-forming tools have completed their return movement and again engaged and gripped the work. whereupon the cam 86 acts to swing the presser-foot upwardly. out of engagement with the work. so as to permit the latter to be fed freely.

The canvas-trimming cutter 36 is mounted adjustably upon the carriage by its dove-tail shank. which is fixed in vertical position. by

means of a clamp-plate 90 and a screw 92,

against a bracket 94L which is fixed, in turn,

by means of a screw 95. to the forward portion of the carriage 38. The cutter may be adjusted vertically upon loosening the screw '92, so as to set it to out only to the required is released. For this purdepth to completely sever the canvas with out mutilating the feather. The bracket 94 has a horizontal .rib-and-groove connection with the carriage, as shown in Fig. 4, so that it may be adjusted'forwardly and rearwardly thereon to decrease or increase the distance of the knife from the lip. Such an adjustment will vary the distance of the cut from the edge of the insole, itbeing remembered that the insole is guided by its rib which lies at varying distances from the idge of the insole. The knife is preferably set so as to engage the canvas at a distance,

from the lip, approximately equal to the width of the narrower portions of the feather, so that at the shank portion of the insole. where the feather is widest, the cut will comewell within the edge. thus insuring that the canvas shall not'be visible in the finished. shoe. lVith such an adjustment of the parts it will be observed that in case the canvas already has been trimmed flush with the insole edge when the insole is brought to the present machine, the knife 36 performs its function only at the shank.

Owing to the fact that the trimming cutter is mounted on the carriage; it oscillates with the lip forming and insole feeding tools. and consequently its cutting operation is performed during the return movement of the latter. Accordingly, the drag of the knife upon the work occurs while the work is held stationary. between the work-support and the presser foot, and this arrangement has the advantage that the operation of the knife does not resist the intermittent feed movement of the insole. Furthermore, the cutting edge of the knife being directed away from the presser-foot provides for a clean severance, that is, there is no opportunity for the fabric to buckle as would be the case if the cutting stroke, were toward the point where the insole is clamped.

The oscillatory feeding movement of the carriage is produced by cam mechanism. For this purpose a block 96 is pivoted to the bottom of the flange 4:0, and is embraced by a forked cam lever98 which rocks upon a pivot-stud 100 in the housing of the machine. as shown in dotted lines in Fig. 3. The cam levercarries a roller 102 which en gages a cam 10% fixed on the power-shaft At each rotation of the shaft, accordingly. the carriage is swung once in each direction to produce a feed movement at each cycle of operations.

While the invention has been describe d as embodied in a machine adapted particularly for perfecting reinforced soles. it will be understood that it is useful also in, and applicable to, sole machines for performing tions, and that the invention is not, in gen eral, liinited to the details of construction and operation of the embodiment hereinbe various other more or less similar operafore described and illustrated in the accompanying drawings. a
