Application filed November 3, 1 8 9 7.

To alt whom it may concern:

Be it known that 1, JOHN B. HADAWAY, a citizen of the United States, residing at Brockton, in the county of Plymouth and State of Massachusetts, have invented certain new and useful Improvements in Insole-Reinfor'cing Machines; and'I do hereby declare the following to be a full, clear, and exact (16". scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to boot and shoe machinery, and more particularly to a machine for applying a reinforcing-covering to insoles, and relates to certain improvements in the form and arrangement of the machine disclosed in my former applications for Letters Patent of the United States, filed on the 23d day of December, 1895, Serial No. 572,972, and the 14th day of February, 1896, Serial No. 579,296. 7

The object of the present invention is to produce a more compact and simplified machine and to improve the operation of the several mechanisms, whereby the machine is capable of a greatly-increased product and.

will be easy and quick in action.

To the above end the present invention consists of the devices and combination of devices which will be hereinafter described and claimed.

The present invention is illustrated in the accompanying drawings, in which similar letters of reference designate corresponding parts, and in which Figure 1 showsa side elevation of the ma chine looking from the right of Fig. 3, portions of the pulley and hand-wheel being broken away and also the lower portion of the standard. Fig. 2 shows a view of the opposite side of the machine. Fig. 3 shows a front elevation of the machine. Fig. 4shows a section of the forward part of the machine below the line x 00 in Fig. 3, showing the stretching-tool in plan, the cutting mechanism being omitted. Fig. 5 represents a vertical section through the work-support.

In the drawings, A represents a standard or base, upon the upper end of which is mounted a frame or head A, which carriesthe operative parts of the machine. The head A snn No. 657,236. '(No was.)

is provided with upwardly-extending standards a, which at their upper ends are provided with suitable bearings a, in Which is mounted the main shaft 13, said shaft carrying upon its rear end a pulley b and at its forward end a combined cam and hand wheel I) and between its bearings a cam-drum 5 Projecting from the front of the machine is a bracket b which carries a bearing b in which is received the shank c of a work-support O, which is rotated step by step by mechanism which will be hereinafter described.

The machine of the drawings comprises a presser-tool D,which is carried by a bell-lever cl, which is fulcrumed at 61' upon the fixed frame of the head A and which at its opposite end carries an antifriction-roll d which engages a cam-groove 19 cut in the cam-drum b whereby upon a rotation of the shaft 13 said bell-lever dwill be oscillated and impart an up-and-down movement to the pressertool D to alternately clamp and release the work which is superimposed upon the worksupport 0.

In order that the presser-tool D may yield vertically as it contacts with the insole, the shank of said tool is fitted in a guideway d to have a free sliding movement therein, said movement being limited by a stud 61 carried by said shank, which engages a slot d in a retaining-plate d, the upper end of the shank being acted upon by a spring d which is secured to the side of guide 01 For the purpose of providing for an adjustment of the presser-tool D toward and from the beadforming tools to provide for insoles of various widths of feather the guide 01 is provided;

with a shank. d and one end of the lever d provided with slots d to receive the setscrews at which take into screw-threaded apertures in the shank d and by means of which the guide cl is adjustably secured to said lever. The above-described arrangement is such that a rotation of the shaft B will by means of the bell-lever d impart a movement to the presser-tool D toward and from the insole superimposed upon the worksupport 0 and press the reinforcing material against the inner face of the lip or against the end of the former or anvil, which will be hereinafter described.

The anvil or former E consists of a thin plate of metal which is secured to a support 6 by a setscrew e and has upon its outer end a tapering upturned bead, forming projection or finger e the said finger being upwardly and outwardly bent, as clearly shown in Figs. 1 and 2, and extends over the work-support O in position to be projected beneath the reinforcing material, over which the reinforcing material is formed by the presser-tool and bead-forming tools, as will be fully described.

Cooperating with the anvil or former E is a movable bead-formin g tool F and a fixed tool G, the movable tool F acting to bend down and press the reinforcing material over the anvil or former to form the bead or crimp therein, and the fixed tool G is secured to the front of frame A by a set-screw g and acts upon the insole after it has been acted upon by the movable tool F and, resting again st the outer side of the bead or crimp, acts as a guide for the work, and the lower end gives a final smoothing and pressing to the reinforcing material upon the feather.

The tool F comprises a tapering plate of metal f, which at its lower end has a finger f which is arranged to pass downwardly alongside of and close to the bead-forming finger e of the former or anvil E to bend the reinforcing material over said bead-forming finger, and said tool also comprises a thin plate f which is affixed in position in front of the plate f, the lower end of the thin plate f being considerably Wider than the finger f on the plate f and terminating in a bent portion f slightly above the end of the finger f in position to act upon the reinforcing material upon the upper surface of the finger e of the anvil or former E. The finger F is secured to the front of a vertically-reciprocatin g slide f by the set-screw f which passes through slots (not shown) formed in the upper ends of the plates fand f the upper end of the beadforming tool F being acted upon by a screwstop f", threaded in a bearing formed upon the front of the slide f", whereby said tool F is fixedly held in position and may be accurately adjusted upon the slide f The slide f is arranged for vertical reciprocation in a guideway f (see dotted lines, Fig. 3) and carries at its upper end a cam-rollf which takes into a cam-path formed in the rear face of the cam-disk b, forming a part of the combined cam and hand wheel 6, whereby said slide f is reciprocated vertically to impart a movement to the bead-forming tool F toward and from the work upon the work-support O.

In order to impart a lateral movement to the bead-for1ning tool F to cooperate with the work-support O in feeding the work, the guideway f 8 is formed in a horizontally-sliding block f held in a horizontal guideway f, formed in the front of a fixed portion of the head A and held in said guideway by suitable retaining-plates f or in any other suitablemanner.

The horizontal movement of the block f is imparted by a two-arm lever f fulcrumed at f upon a stud f which is fixedly secured in a pinch-clamp f carried by an arm f", projecting from the fixed head A. The lower end of the lever f is forked and embraces a stud f mounted in an cal-f formed on the block f and the upper end of the lever f carries a cam-roll f which engages a campath f, formed in the front face of the camdrum U The above-described arrangement is such that a rotation of the main shaft B will, by means of the cam-path f and the lever f, impart a horizontal reciprocating movement to the block f carrying the guide way f thereby imparting the lateral reciprocation to the bead-forming tool F, and at the same time the vertical reciprocation is imparted to the tool F by the cam Z) acting upon the slide f. The work-support C may be simply mounted to have a free rotary movement in the bearing 11 and be rotated by the frictional engagement of the work against the surface thereof as said work is forced thereagainst by the bead-forming tool F; but to insure perfect accuracy in the feed of the work the work-support O is arranged to be positively rotated step by step in the direc tion of the feed of the work and in unison with the movement of the bead-forming tool F in the same direction. The work-support C, as before explained, has a shank c, which is fitted to rotate in the bearing b and said work-support G is held elevated by a spring which acts on a head which receives and supports the shank 0, whereby said work-support C is forced upwardly to clamp the work against the fixed tool G.

The shank c of the work-support C is loosely connected with a rod 0', which is connected by a wire or chain c to a treadle, (not shown,') whereby the work-support C may be depressed for the purpose of placing the work thereon under the bead-forming tools. Within the bearing 6 is a sleeve 0 which is mounted to rotate therein and in which the shank 0 is directly received, the said shank being freely vertically movable therein, but splined to said sleeve 0 to turn therewith.

Upon the lower end of the sleeve 0 below the bearing 1), is mounted a ratchet-disk c, rigidly secured to the sleeve 0 Above the ratchet-disk c is a loose collar 0 which is arranged to be freely movable about the sleeve 0 and which has a projecting lug c carrying a pawl 0 which is held by a spring 0" against the ratchet-disk 0*.

In order to oscillate the collar 0 to cause the pawl c to rotate the ratchet-disk c, said collar is connected to a link 0 which is pivotally connected at c to the lug c and at its opposite end is pivotally connected to a stud e carried by the arm 0 of a bell-crank lever a. The bell-crank lever e is fulcrumed at 0 upon a stud or post 0 and the other arm 0 thereof is provided with a segmentgear 0 as clearly shown in Figs. 2 and 4.

The bell-crank lever c is actuated by a two-armed lever 0 which is fulcrumed upon a stud e held in a pinch-clamp 0 upon the fixed frame or head A.

The lower arm 0 of the lever 0 has a segmental gear c ,which is in mesh with the gear 0 of the lever 0 and the upper arm 0 of the lever 0 carries a cam-roll 0 which engages a cam-path (not shown) formed in the rear face of the cam-drum 12 The above-described arrangement is such that a rotation of the main shaft B will, by means of the lever e impart an oscillation to the bell-crank lever 0 which will impart a reciprocating movement to the link 0 which will oscillate the collar 0 upon the sleeve 0 and cause the pawl to rotate the ratchetdisk 0 and thus impart a step-by-step rotation to the work-support O, the rotation being simultaneous with the lateral movement of the bead-forming tool F in the direction of the feed, whereby the insole,which is clamped between the work-support C and the beadforming tool F, will be fed step by step to bring successive portions of the edge of the sole in position to be acted upon by the beadforming tools.

In the formation of the bead or crimp the anvil or former E is projected beneath the edge of the reinforcing material, and in order to facilitate the proper positioning of the work and its removal from the machine without the liability of displacing the reinforcing material along the edge of the sole the former or anvil E is arranged to have a vertical movement toward and from the bead-forming tools with the work-support, and such movement is preferably accomplished by the movement of the work-support by the following mechanism: The upward movement of the work-support O is controlled by an adjustable stop h, which is secured fixedly to the rod 0 and which strikes against an adjustable stop 71', shown as a nut or sleeve 7L secured in a bearing 72?, carried by a bracket 7L4, projected from the front of the frame A. Connected to the rod c be low the stop it is clamp 71 which is provided with a projecting arm h, carrying at its outer end an eye 7L7, which receives a rod h and along which said eye is free to move. The rod h is pivotally connected at h to the support 6 of the anvil or former E, said support 6 being fulcrumed at e to a standard 6 projecting upwardly from the base of the head A and which is secured on said base by the screws 6 (one only being shown,) whereby the standard and support 6 may be adjusted back and forth to vary the position of the anvil or former E relatively to the work-support O and to bring its bead-molding finger edirectly in line with the outer plate f of the beadforming tool F. The rod h is provided with a stop-n ut 72 which is threaded upon the end thereof below the eye it and at its upper end is surrounded with a coiled spring h, which bears at one end against a nut h on said rod and at its lower end against a rest or guide 71 carried by an arm h, projected from the standard a, and said rod h carries a stop-nut it below the guide 71, which forms a stop to limit the upward movement of the rod h and the anvil or former E.

The stop h is preferably arranged upon the rod h at a short distance below the eye 7L7, so that the rod 0 may be moved downward slightly before the eye 71 comes in contact with the nut 71, to cause a downward movement of the rod h and thus the work-support 0 may be depressed slightly without imparting any movement to the anvil or former E, such depression causing the work-support to move away from the anvil or former a sufficient distance to permit the insertion of the edge of the shoe-sole between the upper surface of the work-support and the under surface of the former or anvil. The above-described arrangement is such that a downward movement of the rod 0 will move downward the work-support 0, moving said work-sup port away from the anvil or former to release the work, and when the eye 77, comes into contact with the nut h the rod 72, will be drawn down against the tension of the spring h and move the support 6 about its fulcrum 6 thus causing the forward end of the anvil or former E to move downward with the work-support C in the further movement of said work-support. Upon the release of the work-support it will be moved upward by its spring and at thesame time the spring it will raise the anvil or former, its upward movement being limited by the stop-nut L Cooperating with the bead-forming tool is a stretching device which is arranged to engage and stretch the projecting edge of the reinforcing material just prior to its being acted upon by the bead-forming tools, so as to remove all surplus material and insure the even'and smooth application of the reinforcing material to the insole. This stretching device consists of a roughened foot or tool k, which is secured to the downturned end of a shank 70 said shank at its opposite end being adj ustably secured by means of a slot k and screw 70 to a short lever M, which is fulcrumed upon a stud lo, whereby the shank k is arranged to have a vertical movement to move the stretching foot or tool 70 toward and from the anvil or former E. The stretchingtool 70 is also arranged to have a movement in an inclined or oblique direction across the reinforcing material which may be superimposed upon the anvil or former and also a movement toward and from the medial line of the insole, and such movements in the machine of the drawings may be conveniently produced by the following mechanism:

The vertical movement of the stretchingtool 70 is imparted in an upward direction by an arm or bracket 7.4 which is secured by a screw k to the side of the slide f of the beading-tool F and projects laterally therefrom across the front of the machine, then backwardly and downwardly, and thence inwardly beneath the shank 70 of the stretching-tool ICO 70. A spring is secured at one end to the lever 70 and at its opposite end to an eye It, carried by the link 0 the spring 70 acting to impart to the stretching-tool k a yielding downward movement to cause said tool 7; to engage the reinforcing material.

The movement of the tool is toward and from the medial line of the insole is imparted by the bell-crank lever the stud k being mounted in a lever 70 which is fulcrumed upon the upper end of the stud 0 The oblique movement of the tool 7t as said tool is reciprocated back and forth by the bell-crank lever is caused by a stud k, which is project-ed vertically from the inturned end of the arm or bracket if, which stud 7t engages a slot 70 formed in the shank 7c of the stretching-tool 7a.

The above-described arrangement is such that the tool 7t will be moved up and down in unison with the movements of the tool F, and by means of the bell-crank lever o and the stud-and-slot connection described said tool 7t will be moved back and forth over the work in an oblique direction, thus engaging the reinforcing material and exerting pressure thereon against the anvil or former E and taking up any slack or pucker which may be in the same.

The machine of the drawings comprises a trimming mechanism which acts upon the edge of the reinforcing material as the sole is fed along after the bead-forming tools have acted thereon and trims off the edge of said material to correspond to the edge of the insole. This trimming mechanism comprises a pair of disk-cutters m and m, the cutter an being carried upon the forward end of a shaft m and the cutter m upon the forward end of a shaft m the said shafts being mounted in suitable hearings in a carriage m", which is arranged to have a movement toward and from the work-support C, for a purpose to be hereinafter described.

The shafts m andm are rotated sim ultaneously in opposite directions in the following manner: Shaft m is extended beyond its bearings in the carriage m and upon the end thereof is a lug m which engages a slot m in a drum m carried by a shaft miwhich is mounted to rotate in a bearing an upon the upper end of a standard m projecting upwardly from the base of the frame or head A, and said shaft m carries a belt-pulley m, which may be rotated by a belt from any suitable source of power to impart a rotary movement to the shaft m and drum m and by means of the lug m impart rotary movement to shaft m carrying the disk-cutter m. Upon shaft 'm is a pinion m which meshes with and drives a similar pinion on upon shaft m whereby a rotary movement will be imparted to the shaft m by the shaft m Shaft m is arranged to have a longitudinal sliding movement in its bearings in the carriage m and surrounding said shaft is a coiled spring m, which bears at one end against the carriage m and at its opposite end against a collar m fixedly secured upon the shaft m whereby said spring will normally force the shaft m backwardly in order to maintain the cutting edges of the cutters m and m in close contact with each other to properly act upon and sever the projecting edge of the reinforcing material.

In order that the cutters m and on may freely move toward and from the work-support 0 to accommodate themselves to the varying curve of the edge of the insole, the carriage m is arranged to be freely movable back and forth from the work-support G.

In the machine of the drawings the carriage on" is connected by means of adjusting-screws m to a bar on, and said bar is pivotally connected at m to a pair of swinging levers m which are fulcrumed at m to the fixed frame A of the machine. One of the levers m has a projecting arm m which is arranged to have a limited movement between adjusting screw-stops 011 threaded in hearings in lugs m of the fixed f 'ame A, and said arm on? is connected to one end of a spring m the opposite end of which is fixedly secured to one of the lugs 072 The above-described arrangement is such that as the insole is fed along beneath the bead-forming tools the cutters m and 'm are rapidly rotated by means of the pulley m to trim and cut off the surplus reinforcing material which projects beyond the edge of the insole, it being understood that the face of the lower cutter m rests against the edge of the insole,which is superimposed upon the worksupport 0, and as the insole moves along the carriage m which is yieldingly pressed forward by the spring an, it will be permitted to move freely backward and forward toward the work-support C in order that the cutters m and m will conform accurately to the contour of the edge of the insole and will accurately trim and out off the projecting edge of the reinforcing material along the line corresponding to the edge of the insole.

By means of the adjusting-screws m the bite or meeting edges of the cutters 'm and m may be adjusted vertically to position said cutters relatively to the plane of the reinforcing material, and by means of the adjusting-screws m the horizontal movement of the carriage m and the cutters may be accurately adjusted. In the formation of a lipped insole the lip is oftentimes formed at varying distances from the edge of the insole, it being placed farther from the edge along the shank of the sole and nearer the edge along the fore part, thus resulting in a variation in the width of the feather of the insole along the shank and fore part, and inasmuch as the carriage m and the knives m and m are freely movable toward and from the medial line of the sole it results that said knives will automatically position themselves according to the variations in the width of the feather.

The operation of the machine of the drawings is as follows: The insole having been provided with a reinforcing-covering which has been temporarily cemented to the upper face thereof along its medial line, leaving the edge of the reinforcing material loose and projecting over the edge of the lip and beyond the feather, is superimposed upon the work-support O. In placing the insole upon the work-support C said work-support is depressed against the tension of its spring by a downward movement of the rod 0, produced by means of the treadle, (not shown,) and the insole is placed in position with the lip thereof against the bead-molding finger e of the anvil or former E, and the projecting edge of the reinforcing material resting upon the upper surface of the anvil or former E and over the bead-molding finger e The worksupportis then permitted to rise and the feather of the insole is clamped between the upper surface of the work-support and the lower surface of the fixed bead-forming tool G, said bead-forming tool G resting upon the reinforcing material immediately over the feather of the insole. The rotation of the main shaft B now acts through the bell-crank lever d to force the presser-tool D against the reinforcing material upon the face of the insole and presses said reinforcing material against the inner face of the lip, after which the bead-forming tool F is forced downwardly by the cam b and by means of the finger f thereon presses the reinforcing material down alongside of theouter side of the lip and against the feather, and the finger f will press the reinforcing material against the upper edge of the beadernolding finger e of the anvil or former E. The presser-tool D is now raised, releasing the insole, and the slide f moves toward the left in Fig. 3 by means of the lever f thereby moving the bead-forming tool F to the left, and simultaneously with the movement of the bead-forming tool F to the left the work-support C will be rotated one step, thus feeding the work toward the fixed tool G and the cutters m and m. The tool G rests against the outer face of the lip and acts to press and smooth the reinforcing material against the lip and upon the surface of the feather, and as the work continues to move toward the left the rotating cutters m and m will sever the projecting edge of the reinforcing material and remove the same even with the edge of the feather, as before described. After the bead-formin g tool F has moved to the left to the limit of its stroke it is raised from the work and returned to the right in position to descend upon the reinforcing material at a new point and mold the same, as before described. Prior to the action of the bead-forming tool F upon the reinforcing material the stretching-tool 73 has been raised by the arm 71: and moved forwardly by the bell-crank 0 and as the tool F descends the spring depresses the stretching-tool 7t and causes the same to engage the upper surface of the reinforcing material and press said reinforcing material against the anvil or former E, and upon a retraction of the stretching-tool k by means of the bell-crank said tool will drag over the reinforcing material and take up any slack or puckers which may have been therein, thus causing the reinforcing material to be evenly and accurately cemented to the insole and lip without any objectionable puck ering or wrinkling thereof.

Having thus described myinvention and its mode of operation, I'claim as new and desire to secure by Letters Patent. of the United States 1.
