SOLE CHANNELING AND TRHVIIVIING MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,883, datedMareh 22, 1898.

Application filed December 5, 1894:. Serial No. 580,849. (No model.)

To all whom, it may concern.-

Be it known that we, WILLIAM C. MEYER and ZACHARY T. FRENCH, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Sole Channeling and Trimming Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings represent-inglike parts.

This invention relates to a machine for operating upon the soles of boots and shoes, having more particular reference to machines designed for either trimming or channeling the soles of welted boots and shoes or for both trimming and channeling said soles when upon the last.

One of the essential objects of this invention is to provide means whereby the sole may be trimmed at different distances from the last or inseam, that the sole edge may proj ect a short distance along the shank portions and a greater distance along the fore part, producing what is commonly termed a scotch edge, and another essential object is to channel a scotch-edged sole. In producing the variation thus required for the projecting edge of the sole we employ two independent guides, one working along the shank portions and the other working along the fore part, they operating successively around the boot or shoe as it is trimmed or channeled, or both.

The shank-guide may be made stationary and the fore-part guide movable, and when so constructed the shank-guide may, if desired, serve as a work-support,while the forepart guide when brought into use may move the boot or shoe more or less away from the shank-guide, and such movement of the forepart guide may be gradually performed, so as to avoid any abrupt formations between the shank and fore part.

In the manner in which we have herein seen fit to carry out our invention the shank-guide is shaped to enter the crease or inseam and the fore-part guide is shaped to bear against the upper drawn over the last, near to but not entering the crease, so that the shankgnide acts as a crease guide and the fore-part guide as a last-guide.

We desire to hold the boot or shoe edgewise, and therefore the guides are disposed in such manner that this may be done.

Feeding mechanism is provided for feeding along the boot or shoe, and the construction herein described also forms'a part of our invention.

The channeling-knife is made to reciprocate or act intermittingly in cut-ting its channel and is also made vertically movable, in order that the channel maybe cut more or less distant from the edge of the sole. As such variation is desirable between the shank and fore part of the sole, we preferably connect the means employed for vertically moving the channel-knife with the operating mechanism of the fore-part or last guide that they may act simultaneously.

The trimming-knife is arranged to vibrate or oscillate in a direction toward and from the operator, acting upon the bottom of the sole and in cooperation with or against a cutting-block,which is located upon the other or welt side of the sole, said block being firmly held or supported so as to resist the pressure of the knife, and having a plain face against which the cutting edge of the knife acts to prevent the formation of a ragged edge. This cutting-block is herein represented as forming a cooperative part of the feeding mech anism.

Figure 1 is a left-hand side elevation of a channeling and trimming machine embodying this invention, one of the side walls of the frame being broken away to expose the operating parts, which are in their normal position of rest; Fig. 2, a detail showing in plan View the Work-support or shank or crease guide and a cooperative part of the feeding mechanism and adjacent parts; Fig. 3, a detail showing the shank or crease guide in engagement with a shoe; Fig. 4, a detail showing the fore-part or last guide in engagement with the shoe; Fig. 5, a right-hand side elevation of the machine, the fore-part or last The boot or shoe to be channeled or trimmed, or both, is held up edgewise against a guide or work-support a,which is made with a tapering end adapted to enter the usual crease or inseam between the welt and upper, said guide being herein represented as a bailshaped piece of metal secured to and depending from the extremity of a skeleton or twoarmed bracket a,which is secured to the baseplate A of the framework. As the function of this part a to serve as a guide is utilized in the shank portion particularly, it may be referred to as a shank-guide.

The channeling-knife I) (see Figs. 11 and 12) is formed upon or projects from a block I), made substantially semicircular in shape and secured in a recess formed in the upper end of a vertical pin or post 19 depending from a plate b which is screwed or otherwise secured to a rearwardly sliding or yielding holder Z9 As a preferable way of securing this block b in place we have cut away or grooved horizontally the vertical side wall of the recess which is formed in the upper end of the post b and have provided the inner or fiat face of the block b with a horizontal projection 2, which enters said groove, and a setscrew (see dotted lines, Fig. 11) passes transversely through the upper end of the post b entering a threaded hole 3, formed in the block b. An antifriction-rollerb is mounted to turn freely upon the vertical post or pin b it being held thereon by a nutb or otherwise. The upper end of. the post Z9 together with the block 1), forms a head which is larger in diameter than the lower part or shank of the post, and the upper end 4 of the antifriction-roller b is bored to receive said enlarged head, so that the block b is inclosed or concealed by the upper end of the antifriction-roller. This antifriction-roller serves as a support against which the bottom of the sole to be operated upon bears, and therefore may be referred to as a sole-support.

The antifriction-roller is preferably circumferentially concaved below the flat portion 4 to permit the boot or shoe to be tipped a certain degree, if desired.

The antifriction-roller may be omitted, in which case the post may be formed to serve as the sole-support; but its employment is by far preferable.

The sliding tool-carrying block or holder 77 has a dovetailed groove b in its upper side, which receives a dovetailed block 19 (see dotted lines, Figs. 1 and 2) on an arm 6 pivoted at Z1 to the base-plate and swinging in a horizontal plane. At the rear end of the dovetailed block b a cross-piece b is secured, against the rear side of which, at each end, a strong spiral spring I) bears, the opposite or rear ends of said springs being connect-ed with adj usting-screws Z9 turning in suitable ears I), projecting from each side of the hub of the arm Z)". The cross-piece Z9 is pressed forward by the springs 6 so that it bears against the rear end of the block I), thus limiting its forward movement. The springs 6 yield as pressure is exerted upon or against the antifriction-roller 12 or when the toolcarrying block b is otherwise moved rearwardly by means to be described. Rearward movement of the tool-carrying block b is necessary for the purpose of introducing the work between it and the work-support or guide a, and the springs are employed to press said tool-carrying block forward that it may hold the work against the work-support or guide or against any other part that may be brought into engagement with the welt at the welt side of the sole. Spring-pressure is preferred for the reason that it permits the parts to automatically adjust themselves for different thicknesses of soles.

The sliding tool-carrying block b has on it a projection Z9 which is engaged by a crank-arm 0, (see dotted lines, Fig. 5,) projecting from a shaft 0, having its bearings in the framework, said shaft being supplied at its outer end with another crank-arm 0 which is connected by a chain or otherwise with a treadle, (not shown,) so that by depressing said treadle the slide-block b will be moved rearwardly with its channelingknife for the insertion of the work to be done. As this yielding block bears against the bottom of the sole it is designed to utilize it as a cooperative part of the feeding mechanism for the boot or shoe, and as one Way of carrying out this result the arm 19 is vibrated in a horizontal plane, oscillating on the pivotpin b rising from the base-plate. A pin Z2 rises vertically from the top of the arm 19*, which enters a cam-groove Z7 formed in the pulley or hub B, secured to the main shaft 0, and as said pulley or hub revolves the pin 5 following the groove, causes the arm 5 to vibrate on the pivot Z7 As the arm I) is swung back and forth the sole-support, being spring-pressed, is caused or permitted to move in a straight line.

To complete the feeding mechanism, a plate 61, made tapering toward its lower end and having a substantially fiat inner face, is adapted to bear upon or against the welt or welt side of the sole opposite the antifrictionroller 1), said plate being rigidly secured to or formed integral with an arm d, projecting from av hub or support (1 mounted upon a rod or bar 61 which has two rearwardly-ex tended projections or arms 01 d The arm d enters a cam-groove h in the pulley or hub B, and as the latter is revolved a longitudinal reciprocating movement is imparted to the hub or support 61 bearing the feedingplate d, and the arm (1 has a laterally-extended pin 01 which enters another camgroove Z7 in the pulley or hub B, and as the latter revolves said hub or support 01 bearing the feeding-plate d, is rocked or oscillated on the bar d supporting it or upon which it is mounted. This mechanism or some equivalent mechanism which may be provided in lieu thereof gives to the plate at alateral and an in-and-out movement, or what is ordinarily termed a four-motion movement.

, The operation of the feeding devices in feeding along the shoe is as follows: The sole and welt, held edgewise, are introduced, the roller 5 bearing against the bottom of the sole and the work-support a and plate (1 being upon the welt side. If the plate cl is in its forward position, the work will be held stationary by and between the roller 12 and work-support a. Suppose the plate cl to be at the extreme right. It is then brought into engagement with the welt, so that the work isthen clamped between the plate (Z and roller 19 The plate d and roller b are then moved together their full distance toward the left, carrying the work along with them. Then the plated is moved out of engagement with the welt, leaving the work to be held by and between the roller 19 and work support a, and while the work is so held the plate 01 moves toward the right, and while acting in conjunction with the trimming-knife e, to be described, or other part to hold the work the roller b moves its full distance toward the right, so that when the plate 01 againengages the welt a new grip is obtained that the operation may be repeated and the work thereby fed along intermittingly.

It will be observed that the work-support a and plate 61 act alternately upon the welt, one being stationary and the other movable; but so far as our invention is concerned we desire it to be understood that we do not limit our invention to which part moves, as it is obvious that the part ct could be made movable in the same manner as the part d and the part 01 made stationary. We prefer a stationary work-support, as it serves as a fixed point againstwhich the operator may hold the work.

To trim the edge of the sole, a vibrating or oscillating knife 6 is provided, shown as attached to an arm 6', projecting from a hub 6 mounted upon the rod or shaft d and an cecentric disk 6 on the main shaft 0 has its strap 6 connected by a link (2 with said arm 6, being employed as a means of vibrating said arm to thereby oscillate the knife. The knife 6 is made trough-shaped, sharpened at the end, and provided witha dovetailed shank (see Fig. 15) which fits a dovetailed groove or recess in a slitted block 6 which is secured to the arm e, a clamping-screw 6 being provided for drawing the slitted portions of said block together to securely bind the knife in place. The knife works against the bottom of the sole and, as herein represented, toward and from the operator, and in order that it may penetrate the material a substantial support is required for the opposite or welt side of the sole, and to provide such a support without increasing the number of parts, and thereby complicating the construction of the machine, we have constructed and arranged the cam which rocks the hub 61 of the clamp ing or feedingplate dso that during the re turn movement of' said plate at from left to right it will be brought into engagement with the welt at the welt side of the sole just opposite thetrimming-knife and there held for a short interval of time to thus firmly support the sole at such point while the knife cuts the material. Hence it will be seen that the plate d, in addition .to serving as a cooperative part of the feeding mechanism, also serves as a cutting-block or solid foundation to resist the pressure or thrust of the knife. The plate 61 is made with a plain or smooth face against which the cutting edge of the knife acts,so as to insure a smooth or clean cut, for when the cutting edge of the knife enters a slit a ragged edge is produced.

The operation or movement of the parts in channeling and trimming is as follows: The plate d and roller 5 or its equivalent, being operated upon by their respective cams are moved from right to left together, asbefore stated, the sole and welt being clamped or held between them. Then the plate dis moved outashort distance, disengaging the welt, and at such time the sole and welt are held between the spring-pressed roller and the stationary work-support a, the channeling-knife being seated in the sole. Then the plate at is moved toward the right a short distance, then in again, engaging the sole at a point just opposite the trimming-knife. The trimmingknife is then brought forward, and while it is penetrating the material it, together with the cutting block or plate 01, holds the work while the roller 17 moves its full distance from left to right, the channeling-knife during such time cutting the channel. Then the plate at again recedes and moves another short distance toward the right, the work being again held by the roller 12 and'work-support a, and then said plate 01 moves again into engagement with the welt. All the movements of the parts having thus been completed the operation is repeated, feeding the boot or shoe along during its movement from right to left.

It will be observed that the channel-knife is borne by a cooperative part of the clampfeeding mechanism and when seated in the sole moves therewith during the feeding operation, and that the channel-slit is cut dur ing the return movement of the partcarrying it.

Nhile channeling the boot or shoe in or along the shank portions, the work-support a is used as the guide, it entering the creaseor inseam between the Welt and upper; but when channeling along the fore part itbecomes necessary or very desirable to guide by the last instead of by the inseam, and hence we have provided another guide, which is termed a fore-part or last guide and is adapted .to be brought into operative position at the proper time, it being herein represented as a bent arm f, secured to the outer end of an arm f, pivoted at f 2 and connected by a rod, cord, or chain with a foot or knee operated ICC IIC

treadle, so that whenever it may be desired the treadle. may be depressed and the fore-. part or last guide, which is normally in its elevate position, as shown in Fig. 1, thrown into engagement with the, fore. part of the boot or shoe, as shown in Fig. 4, the lowerend of the part f at such time bearing upon the upper, drawn taut over the last. This. independent fore-part or last guide is very useful in connection with either a channeling or trimming knife, or both, or, in fact, in connection with any tool or tools adapted to operate upon the soles. of boots or shoes where a guide of such a character is. necessary. Hence we desire to havev it understood that our invention is sufficiently broad in scope as to include two separate guides, one acting along the shank and; the other along the fore part and operating successively around the.

boot or shoe; but the specific form. of guides shown, whereby the trimming-knife or other tool is guided by the. crease along the. shank portion and by the last around the fore part, is, we conside -7, a preferable form. to. employ. This fore-part or last guide, while very desirable, may be omitted and in such case. the work-support a. used as. the crease-guide all around; the shoe or the portion which is being trimmed or trimmed and channeled. It is also very desirable to, vary the distance-from I the edge of' the sole that the channel shall be 1 cutas, for instance, it is deemed best tocut the. channel; nearer the edge along the fore part than along the shank portion, and. hence the channel-knife holder is. made vertically adjustable. In carrying out thispart of our invention the channel-knifeholder is coincidently raised justv as the fore-part or last j :ported adjacent to the feed-clamp, shaped and; held. in position to enter the crease be- ;tween the welt and the upper and movable i independently of the feed-clamp transversely .tothe directionof the feed, and mechanism 1 for actuating the work-gage during the oper- E ation. of the machine, asthese specific combiguideisdepressed, and hence we have conneeted the vertical adjusting devicesof said channel knife holder with the operating. mechanism of said fore-part or last guide, that they may operatein unison.

Referring to. Figs. l and: 7., a. simple way of. raising the channel-knife holder is shown. The knife-holder is arranged between vertical side plates 12, secured to the end of the rearwardly-sliding block b said:pla, tes.being arranged to present a. vertical dovetailed: guideway, and the channel-knife holder has.

a dovetailed block n fitting. said guideway,

which is provided on its rear side with a.se.

ries of rack-teeth n engaged by a toothed sector or", secured to a short shaft. it, having its bearings in the block b4, andto said short shaft a crank-arm. n is secured, extending rearwardly, which is connected to. the.piv-.

oted; arm f by a spring at and also by alink or pin n', the latter being connected at both ends by ball-and-socket joints or other loose connections. It will'be observed'thatwhem ever the arm f -is depressed the crank-arm n will be correspondingly moved, thereby rocking the shaft n and raising the channel-knife holder. By means of the loose connections shown, whereby the crank-arm n is connected with the arm f, the block 5 carrying the channel-knife holder, may be moved rearwardly as desired.

We do not limit our invention to the particular way herein shown for raising the channel-knife holder or to connecting the adjusting devices thereof with the fore-part guide, as it is. obvious that it may be otherwise operated.

Many of the features herein shown and described are as applicable to. machines for channeling or trimming soles as. for machines having both kinds of tools, and also are applicable tomachines having other tools for acting or operating upon the soles of boots and shoes.

It will be observed that an independent clamp-feeding mechanism, which engages, feeds along, and then disengages the work, permits the bootor shoe to be easily moved out and; in, encountering noresistance, and that thestock cannot be injured as the boot or shoe. is so. moved, and that the work can be moreaccurately and quickly adjusted.

We disclaim the following: in a machine for operating upon the soles of boots andshoes, two independent guides, one working along the shank and the other around the fore part, a fixed guiding device for controlling the location of a shoe while being operated upon by rounding and channeling tools, an adj ustableguiding device adapted tointerpose, so as to force the shoe farther from said tools, andmeansfor advancing and retracing said adjustable guiding device while the tools are in operation; in a rough-rounding and channeling machine, the combination, withthe rough-rounding and channeling knives,of

a clampfeed mechanism, a work-gage supnations of elements are not of our own invention; but thebroadidea expressed as foli1owsto'. wit, the combination of rounding and channeling: knives, feeding mechanism comprising two members which receive be- ;tween them thework andwhieh are operated to feed along the work, and a. guiding device .for the work movablefreely toward and from the rounding and channeling knives during the rounding and channeling operation to .vary the position of theboot or shoe with re- IIO lation to said knives and thereby vary the" widthof the projecting edge of the sole, said guide acting upon the work oppositewhere the rounding is being done, and the combination of rounding and channeling knives and feeding mechanism and a guiding device for the work shaped to enter the crease and movable freely toward and from the rounding .and channeling knives during the rounding and channeling operation to vary the po-- sition of the boot or shoe with relation to said knives and thereby vary the width of the projecting edge of the soleforms the subjectmatter of another applicationfiled by us, Serial No. 572,258, andtherefore such broad features are not herein claimed.

It will be observed that the roller b and channeling-knife support bear against the bottom of the sole laid onto the Welt and directly opposite said welt and that the plate 01 is intermittently moved toward said roller and channeling-knife support positively by a cam to firmly grasp the sole edge and welt between them, and said parts are then moved together laterally to feed along the work, and in so doing they act as a pair of clamp-feeding jaws; but as the welt is severely compressed by the plate d, thus recurrently closing upon it and positively actuated, in many instances no other means for compressing said welt or heating it out becomes necessary, and hence said clamp-feeding jaws possess the capability of compressing or beating out the welt, the plate (1 serving as the welt-beating jaw, and also while the plate (1 is removed from the welt and is returning for a new grip on the work the loop-like work-support or acts, in conjunction with the roller 19 and channeling-knife support, to firmly grasp the sole edge and welt and in so doing to more or less compress said welt during such time.
