JOHN B. HADAWAY, OF BROCKTON, MASSACHUSETTS.

LIP-TURNING MACHINE.

SPECIFICATION forming' part of Letters Patent No. 638,010, dated November 28, 18,99.

Application led October 14, 1897.

1b M whom t may concern:

Be it known that 1, JOHN B. HADAWAY, a citizen of the United States, residingat Brockton, in the county of Plymouth and State of Massachusetts,have invented certain new and useful Improvements in Lip-Turning 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. f

The present invention relates to sole-niachines, and more particularly to a machine for turning up and setting the lip of a lipped insole, such machines being generally known in the art as lip-turning machines.

The present invention has for its object to produce a machine of this character which will expeditiously turn up and set the lip, imparting thereto the desired angular set relatively to the surface of the sole and arranged to act upon the lip in such manner that the fibers of the leather of which the lip is composed, and more particularly at the angle between the lip and feather, will be pounded and compacted, whereby said lip will retain the angular position to which it has been set relatively to the surface of the sole.

The present invention therefore consists of the lip-turning machine Which will be hereinafter described, and particularly pointed out in the claims.

The present invention is illustrated in the accompanying drawings, in which` Figure 1 represents the machine in side elevation with the driving-pulley removed. Fig. 2 represents a top plan view of the machine. Fig. 3 represents a rear elevation of portions of the fixed frame, the driving-shaft, and the main actuating-lever. Fig. 4 represents a broken plan view of the front part of the machine, showing the relative positions of the work-table and gage and theplow and lip-setting tool. Figs. 5 and 6 show a modified form of plow orlip-turner. Fig. 7 represents a vertical sectional View, somewhat enlarged,show ing the construction of the work-support.

Similar letters of reference designate corresponding parts throughout the several views.

In the drawings, A represents a supportingframe of suitable size and shape to support the working parts, which may conveniently `within the tubular bearing c3.

standards a', which may be secured thereto or cast integrally therewith, said standards d being provided with suitable bearings (t3 for the driving-shaft B. Upon one end of the driving-shaft B is a driving-pulley 19 and `a suitable clutch b', whereby said shaft may be rotated to actuate the moving parts of the machine and its rotation controlled by the operator.

C represents a rotating work-support which is carried at the upper end of a short shaft c, which is mounted in a caring c', carried by an elbow c2, extending from the tubular bearing c3, which is afxed to the front of the machine in any suitable manner, as by the bolt c4. The shaft c extends into the tubular bearing c3, as shown in Fig. 7 of the drawings, and it is connected, by means of the headed screw c50,iwith a rod c6, which rod is provided with a hook or other suitable means whereby it may be connected with a foot-treadle (not shown) to depress the work-support C. The Worksupport C is normally held elevated by means of a coiled spring C51, surrounding the rod c(i Splined to the shaft c is a gear c5, by means of which rotary movement may be imparted to the shaft c and the worl-support C.

D represents a feed-wheel which is mounted upon the end of an inclined shaft d,which rotates in a bearing d', formed upon an arm d2, which is projected from a yoke d3, which extends forwardly from the standards a', the feed-Wheel D being at such aninclination relatively to the work-support C that when the insole is superimposed upon the top of the work-support the feed-wheel D will fit into the angle between the lip and featherand bear upon the feather, which will be forced up by 4the upward movement of the work-support C against the under side of the feed-wheel D.

The work-support C and the feed-wheel D are rotated in opposite directions by a worm b3 upon the main shaft B,Which meshes with a worm-gear b4 upon the inclined shaft CZ, and shaft d carries a bevel-gear d4, which meshes with the bevel-gear c5, which is splined to the work-support shaft o. It will thus be seen that a rotation of the main shaft B will, by means of the worm b3,vvormgear b4, and bevelgears d4 and c5, impart a simultaneous rotation to the feed-wheel D and work-support C in opposite directions to feed the work along the lip turning and setting tools to bring snccessive portions of the lip of the insoles under the action of said tools.

If desired, the upper surface of the worksupport C and the underside of the feed-wheel D may be roughened or serrated to insure a better hold upon the work and a more positive feeding thereof.

E represents a plow or lip-turning tool which, as shown in Figs. l, 2, and 4t, consists of a forwardly-projecting curved finger carried by a bracket e, which is mounted upon some fixed portion of the machine-frame, as by a set-screw e', passing through a slot e2 into the bearing d'. The plowE is curved to conform to and is adjusted to closely approximate the periphery of the feed-wheel D, so that it will enter between the lip and feather of the insole, and as said insole is fed along between the feed-wheel D and work-support C the plow E will turn up the lip to be acted upon by the lip-setting tool. It will be observed that-the plow E and the feed-wheelD act in the angle between the lip and feather and gage and position the insole as it is fed along relatively to the lip-setting tool.

F represents the lip-setting tool, which as the sole is fed along acts to impart the proper set to the lip of the sole orto fix it in the position to which it has been raised by the plow E. For this purpose the lip-setting tool F is arranged to im part to the fibers of the lip, and more particularly to the base of said lip, short, sharp, and quick blows delivered in rapid succession, whereby the fibers of the lip are compacted and the lip made to retain the desired position to which it has been placed relatively to the surface of the sole. To secure the above-suggested result in the machine of the drawings, the li p=s'ettin g tool F is arranged to be reciprocated toward and from the edge of the sole upon the work-support, and preferably in an inclined direction, so that the tool F may act upon the lip at its base. For this purpose the lip-setting tool F is mounted upon the end of a slidef, which is arranged to reciprocate in an inclined guidewayf, formed upon the yoke d3, said guideway being so inclined that the plane of reciprocation of the slidefand the lip-setting tool F will be substantially parallel to the upper surface of the feed-wheel D. The slidef is held in position in the guidewayf by a plate f2, which is secured to said guidewayf in any suitable manner, as by the screws f3. The reciprocations of the slide f, carrying the lip-setting tool F, may be imparted thereto by any suitable mechanism, such as alinkf'l, which is pivotally connected to said slidef at f5 and which atits other end is pivotally connected to one end of a shaft f6 in the upper end f7 of a lever f8, which is fulcrumed at ff upon a shaft flo,

` said shaft fw being mounted in bearings a4 in the ends of upwardly-projecting extensions 'd5 of the standards d. The lower end fu of the lever fs is forked and engages an eccentric b5 upon the main shaft B. The abovedescribed arrangement is such that a rotation of shaft B will, by means of the eccentric b5, oscillate the lever f8 upon its fnlcrum flo and by means of the link f4 impart a reciprocatiou to the slide fand the lip-setting tool F, carried thereby, causing said tool to act upon the lip and impart thereto the desired set. The lip-setting tool F is preferably shaped as shown in the drawings, having a working end which is angularly disposed relatively to the shank, and is removably secured to the slide f by a screw s, which passes through a slot s', formed in said shank, whereby said ltool F may be adjusted longitudinally upon the slide f. The working face of the tool F may be shaped as shown, having a substantially straight vertical face to cause the lip to be set vertically at a substantial right angle to the surface of the sole, or the working end of said tool may be shaped to lay over and turn down the lip in a plane substantially parallel with the face of the insole, and in practice it is the intention to provide a number of lip-setting tools having various shapes of working face suitable to position the lip in any manner desired for 'particular work.

While the machine as liereinbefore described constitutes a practicable and operative lip-turning machine which will turn up and set the lip of the sole in the desired position relatively tothe surface of the sole, the thrust of the lip-setting tool against the sole would have a tendency to push the sole off of the work-support, and said sole must be constantly held against the lip-turner E and the feed-wheel D with some force by the operator.

In order to hold the insolein position upon the work-support C and to withstand the thrust of the lip-setting tool F against the lip of the insole, the machine of the drawings is preferably provided with a presser-foot H, which is arranged to grip the insole within the lip and force the same down against the surface of the work-support C, thus clamping the same at the time the lip-setting tool comes into contact with the lip. The presserfoot H is formed uponthe lower end of a rod or stem h, which is mounted loosely in avertical bearing h and prevented from turning therein by any suitable means, such as a pin h2, engaging a slot h3 in said bearing. The presser-foot H is arranged to be moved toward and from the surface of the work-support C to alternately clamp and release the sole thereon, and such movement may conveniently be secured by the following mechanism: The bearing 7L is secured to the forwardly-extending arm h4 of a three-armed lever h5, the lower arm h6 of which is forked or yoke shaped and fulcrumed loosely upon a shaft hl, mounted in a bearing carried bythe yoke d3 of the fixed IOO IIO

frame, the other arm 71Sof the three-armed lever 715 being pivotally connected by a stud 719 to a link 7110, which in turn is pivotally connected to one end of the rod f6, carried by the lever f8, the other end of the rod f6 being connected to the link f4, which actuates the slide fand lip-setting tool, as before described. It will thus be `seen that the presser-foot H and the lip-setting tool F are actuated by connected mechanism and move at substantially the same time toward and from the sole upon the Work-support C. The presser-foot H is so positioned that its lower end engages and clamps the work j ust before the lip-setting tool F acts upon the lip, so that when said tool delivers its blow upon the lip the sole will be firmly held by the presser-foot H. The presser-foot is arranged to yield vertically in its bearin g 71, to accommodate inequalities in the thickness of the insole and for different thicknesses of insoles and at its upper end is acted upon by a spring 71u, which has a slot 7112, which engages a head 7113, formed upon a screw 7114, which is tapped into a threaded bearing in the end of the stem 71, andthe opposite end of the spring 7111 is secured by a screw 7115 to n a boss 711, formed on the three-armed lever 715.

In order to provide fora horizontal adjustment of the presser-foot H toward and from the lip-setting tool F to provide for different thicknesses of lips, the bearing 71 is provided with a bracket 7117, having a slot 711s, through which passes a set-screw 7119, by means of which the bearing 71 is adjustahly secured to the arm 714 of the lever 715. By loosening the .set-screw 7119 the bracket 7117 may be moved in and out upon the arm 714, thus moving the bearing 71 and the presser-foot H, the slot 7112 in the spring 7111 permitting a movement of the head 7113 of the screw 7114 during such adjustment. By lifting the spring 7111 and turning the screw 7114 the tension of the spring 7111 may be adjusted.

In order to accurately adjust the relative times of contact of the presser-foot H and the lip-setting tool F with the work to secure the best results, the stud 719, which connects the arm 7L8 with the link 7110, is an eccentric stud, as shown in dotted lines, Fig. 1, which may be turned to secure the desired adjustment,'

as will be obvious from an inspection of the drawings.

It isof course to be understood that a constant rotation is imparted to the feedewheel D and work-support C to feed the insole, and in order that the contact of the presser-foot Il with the insole and the clampingaction exerted thereon during the instant that the.

presser-foot is in contact with the insole may not retard the feeding movement thereof the presser-foot H is arranged to have a slight `lateral movement with the sole, which is provided for by mounting the lever 715 loosely upon the shaft 717 and providing for a slight lateral play of said lever upon said shaft and also providing for a lateral movement of the arm 718 of said lever upon the stud 719.

(See Figs. 2 and 4.) A spring '111, secured at one end to a stud m' upon a fixed portion of the frame and at its opposite end to a stud m2, projected from one arm or member of the yoked end 71j of the lever h5, acts to hold said lever 715 and presser-foot H in their normal position and to return them to such position from the position to which they may have been moved by the contact of the presser-foot H with the insole.

In practice the end of the presser-foot H may engage and clamp the inner sole at a point in line with the line of movement of the lip-setting tool F, and thus form an abutment against which said lip-setting tool F may press Ithe lip, or said presser-foot H may be set slightly to one side of the line of movement of the lip-setting tool and act merely to clamp the insole against the work-support during the action of thelip-setting tool thereon. In either case the presser-foot is found to be a desirable feature of the machine, inasmuch as it relieves the operator of thestrain necessary to hold the insole in position against the pounding action of the lip-setting tool.

In the operation of the machine the insole, which has been previouslycut or slit around its edge, is placed in position upon the worksupport C with the lip-turnerE and the edge of the feed-Wheel D inserted in the slit, the upper iiap formed by said slit being the lip of the insole, resting against the lip-turner or plow, and the under flap forming the feather of such insole, resting beneath the feed-wheel and lip-turner or plow, the worksupport rising under the action of its spring and causing the feather of the insole to be gripped between the upper surface of the work-support and the feed-wheel. A rotation of the main shaft B now causes a rotation of the worksupport and feed-wheel and feeds the insole, causing the plow or lip-turner to turn up or raise the lip, which is acted upon and given a series of rapid blows by the lipsetting tool to set or shape the same, as has been fully described.

Instead of forming the lip-turner or plow as shown in Figs. l, 2, and 4 it may be constructed as shown in Figs. 5 and 6, wherein 7a shows the bracket and 7s the lip-turner or plow, which' upon its under surface has a cut-away portion 7.52, forming a `flange 713 to Overlie a portion of the periphery of the feedwheel D, the upper surface `of the plow 71 being rounded and beveled o at 7a4, as shown IOO IIO

in the shaded lines of Fig. 6, whereby said i and act upon the lip at the base thereof Within the angle formed by the lip and feather of the insole, substantially as described.
