SOLE TRIM MING AND CHANNELING MACHINE.

SPECIFICATION forming part of Letters Patent No. 630,339, dated August 8, 1899. Application filed February 16,1895. Renewed April 7, 1897 Serial No. 63 1,1 64=. (No model.)

Too/ll whom, it may concern.-

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

In the manufacture of boots and shoes it is sometimes desirable to so out or shape the sole that along the outside of the ball portion of each shoe the sole projects a greater distance beyond the upper than around the toe or along the inside of the ball portion, and prior to this invention, so far as we are aware, such soles have always been cut or trimmed by hand and the channel cut by hand or by the ordinary channeling-machine, wherein the channel-knife is guided by a gage bearing against the edge of the sole.

This invention has for its object to so improve the construction of sole-trimmiu g or sole trimming and channeling machines that this work may be done mechanically, and as a result the boots or shoes which are trimmed or trimmed and channeled are allalike.

Sole-trimmin g or trimming and channeling machines to which our invention is applicable are those wherein the sole is trimmed or trimmed and channeled after it has been socured to and while upon the last, the guide or gage at such time bearing against the upper drawn over the last or entering the inseam or crease at the welt side of the sole, and in carrying out our invention the relative positions of the guide or gage and the sole trimming and channeling knives are changed during the trimming and channeling operationas, for instance, said parts occupy a certain relative position when trimming and channeling the sole along the inside ball portion and end of the toe, but are caused to occupy different relative positions when trimming or channeling along the outside ball portionand by such change in the relative positions of the parts the edge of the sole may be trimmed off so as to project a greater distance beyond the upper along the outside 'bination, with sole trimming and ball portion than along the end of the toe and inside ball portion.

Our present invention therefore consistsin the combination of a trimming-knife, aguide or gage, and means for automatically varyin g the relativepositions of said knife and guide during the trimming operation to Vary the distance from the last that the shoe shall be trimmed,and means for throwing said automatic means into action during the trimming operation; also, in the combination, with sole trimming and channeling knives, of a guide at the welt side of the sole, a support therefor, and means for automatically varying the relative position of said guide and the trimming and channeling knives during the trimming and channeling operation; also, in the comchanneling knives, of a guide at the welt side of the sole, means for automatically varying the relative position of said guide and the trimming and channeling knives during the trimming and channeling operation, and means for throwing said automatic means into action during the trimming and channeling operation.

Herein we have represented our improvements as applied to the sole trimming and channeling machine shown in Letters Patent No.g600,883, granted to us March 22, 1898, to which reference may be had.

Figure 1 shows in side elevation the sole trimming and channeling machine represented in application for Letters Patent Serial No. 530,848, provided with mechanism embody ing this invention for varying the relative position of the guide and knives, whereby the outside ball portion of the sole is made to proj ect a greater distancebeyond the upper than the remaining portion of the sole; Figs. 2 and views of the right and left soles; Fig. 4, a detail of a lifting device for the latch or pawl, which engages a notched collar or hub on a sleeve carrying the cam; Fig. 5, a front view of a portion of the machine shown in Fig. 1'; Fig. 6, a left-hand side view of, the machine shown in Fig. 1, the baseand some of the ad? jacent parts being broken away; Fig. 7, a'de-' tail showing the relative positions of the knife and guide at the junction of the shank and outside ball portion of the left shoe, together with the mechanism for varying their relative positions; Fig. 8, a similar detail showing the relative positions of the knife and guide at the forward end of the outside ball portion of a left shoe; Fig. 9, a similar detail showing particularly the reversed position of the latch or pawl which engages the notched collar or hub, the cam being in the position it will occupy when at the forward end of the outside ball portion of a right shoe; Fig. 10, a section al detail showing the cam and notched collar or hub and rotary reciprocating knifecarrying arm; Figs. 11 and 12, details of the notched collar or hub; Figs. 13, 14, 15, and 16, details of the latch-con trolling mechanism to be referred to.

The machine herein shown and to which our invention is applied comprises, essentially, a

trimming-knife 3, attached to the lower end of an arm 6, projecting from a hub 6 mounted upon the shaft 01 said arm e being connectedby a link 8 with an eccentric-strap which embraces an eccentric disk secured to the main shaft 0, so that as the shaft 0 rotates the knife will be oscillated toward and from the operator acting upon the bottom of the sole. The machine has also a stationary work-support a, made tapering at its lower end to enter the inseam or crease at the Welt side of the sole, and also intermittent feeding mechanism consisting of a yielding vibrating sole-support b acting against the bottom of the sole, and a four-motion plate d, acting against the welt side of the solo. The plate at also serves as a cutting-block, against which the oscillating knife e operates, and the sole-support b is constructed and arranged to carry the channeling-knife b.

The work-support a serves as a rest against the welt side of the sole while the four-motion feeding-plate d is moving and also as a guide to enter the inseam or crease; but its function as a crease-guide ceases when trimming and channeling around the fore part, another guide f, attached to an arm f, pivoted at f being brought into engagement with the shoe during the performance of this part of the work, said guide f bearing against the upper drawn over the last, and therefore may be termed the last-guide. The guide-arm'f is connected by a chain or otherwise with a treadle, so that it may be brought into operative position whenever desired, and whenever brought into operative position the part a serves only as a work-support.

As before stated, in order to carryout this invention we vary the relative positions of the guide and the trimming and channeling knives, and we have herein selected the last-guide f as the guide to be moved during the act of trimming and channeling the sole, so as to vary its position relative to the trimming and channeling knives, because as the machine is herein constructed and arranged this is the guide which is broughtinto operation at that part of the shoe where it is desired to vary the width of the projecting suitable bearin gs provided for it.

portion of the sole. In other trimming of trimming and channeling machines wherein but one guide is employed, which acts around both the shank and fore part of the boot or shoe, our improvements, to be described, are made to act upon or work in conjunction with such guide, whether the guide acts in the crease or against the upper drawn over the last.

The guide-arm f has an upward extension f bearing a cam-roll f and has also at its upper end a latch f, movable obliquely in This latch is herein shown as a pin having a beveled lower end and a cross-piece or pin f at its upper end, and inside the bearing a spring encircles the pin, the tendency of which is to depress it. The upper end of the extension 7 is shouldered or cut away, asshown in Figs. 1 and 16, so that when the pin f is depressed the cross-piece f enters said cutaway portion'; but when raised or withdrawn and given a quarter-turn the cross-piece f will rest upon the upper end of the extension, holding the pin in its elevated position, and when the pin is turned a further quarter .of a revolution in either direction the crosspiece f again enters the cut-away portion as the pin descends.

The oscillating knife-carrying hub or sleeve 6 is extended, as at e along the shaft d (see Fig. 10,) and upon said sleeve-like extension a notched collar or rim 0?. (see Figs. 10, 11, and 12) is placed, which is herein shown as formed with several lateral projections at upon one side and a sinoothreduced portion n upon the other side of its notched part. Pieces of leather may be inserted between the projections n on the notched collar n and a clamping-ring m provided which embraces said projections, and the interposed pieces of leather acting to frictionally bind the notched collar to the oscillating sleeve 6 Another clamping-ring m embraces the smooth portion 12 of the notched collar, which has formed on it a cam m The notched part it of the collar is located beneath the latch f and the cam on beneath the cam-roll f. The armf, carrying the guidef, is normally in its elevated position, as represented in Figs. 1 and 6, and when it is brought into operative position to be used as the fore-part or last guide the cam-roll f will bear upon the cam m as represented in Figs. 7 to 9. While the latch f remains in its elevated position the notched collar 'n is not engaged and the cam-roll f will rest idly upon-the cam, and the relative position of the guidef and trimming and channeling knives will remain the same; but as soon as the latch is operated its lower beveled end enters the notches cut in the part n, as shown in Fig. 7, and as the sleeve e oscillates the cam is intermittingl y rotated until the stop m is brought up against the cam-roll, as represented in Fig. 8. During the travel or progress of the cam m the guide f is automatic- IIS ally gradually raised relatively to the trimming and channeling knives, so that the projecting edge of the sole is gradually narrowed. The shoe thus introduced and referred to is a left shoe, and the edge of the sole along the outside of the ball portion is thus trimmed off and left wider than around the toe and inside ball portion.

When trimming and channeling the rightshoe, the work is begun at the right-hand side, as in the left shoe, and while the latch f remains in its elevated position the camroll f rests idly upon the cam m at its highest part, (see Fig. 9;) but just after passing around the toe the latch f is turned in the opposite way to that previously described, entering the notched collar with its beveled end turned in the opposite way, so that as the sleeve 6 continues to oscillate the cam is intermittingly moved in the opposite way, the

cam-roll following along the gradually-re-.

duced portion of the cam, and the guidef automatically gradually lowering relatively to the trimming andchanneling knives along the outside of the ball portion of the shoe until the stop m is brought up against the camroll and the edge of the sole will at such time project widest from the upper. At the beginning of the shank portion this fore-part or last guide is removed from its engagement with the shoe and the trimming and channeling operation continued, the shoe being guided by the work-support or crease-guide a. Thus the intermittent motion of the cam m is reversed for right and left shoes, so that by employing a single cam both shoes may be trimmed or trimmed and channeled in the peculiar style desired, leaving the wider projecting edge of the sole along the outside of the ball portion in each shoe.

As a simple and efficient means of operating the latch f 14 we may employ the following mechanism, (see Figs. 1, 4:, 5, 6, and 13 to 16:) A rod 19 is arranged horizontally in bearings 13, secured .to the framework, and to said rod is affixed a finger 19 the upper side or face of which is beveled in opposite ways, and this finger projects toward the latch, but located beneath the cross piece or pin f when the latch is in its elevated position, and is arranged to act upon said pinf as will be described. The rod 13 is movable longitudinally in its bearings in order that the finger 19 may occupy a position with one or the other beveled face directly beneath the pin f on the latch f, and said rod is also free to be turned or rocked that the finger 11 may be lifted to permit the return of the pin. A detent w is pivoted to a stud 5, projecting from a part 19 on the rod 1), but connected and movable longitudinally with said rod, said detent engaging a cut-away plate to on the frame when the rod is in its extreme left-hand position, a spring 1H2 being connected to said detent to draw it in. A spring to encircles the rod p and is connected at one end to the frame and at the other end to the finger 19 or it may be the rod, the action of which is to move the rod and its attached finger 19 toward the right whenever the detent w disengages the plate 10. An arm 104 is secured to the shaft of the guide-arm f, which has a spring-pressed latch L05 at its upper end, which as the guidearm is depressed strikes and disengages the detent w to thereby allow the rod 19 to move toward the right. The rod p and its attached parts are afterward moved toward the left or restored to their normal position by the operator pressing upon the knob 10 Assuming the parts are in the position shown in Figs. 5, 13, and 15 and the operator desires to vary the width of the sole, he depresses the arm f by means of a treadle connected thereto, and in doing so the pin strikes the right beveled face of the finger 172, and moving along said face is lifted and also turned substantially a quarter of a revolution, as shown in Fig. 16, and the latch to then strikes the detent w, disengaging it from the plate to, and the spring-pressed rod 19 thus released is moved toward the right, carrying with it. the finger 19 which is fixed to it, and the latter during its passage strikes the pin f and turns it farther to the right,

so that it will fall .into the cutaway portion, and at such time the latch f is thrown into engagement with the notched collar. The guide-actuating cam is then intermittingly turned. It will be seen that the latch f is thus automatically turned one way by the act of depressing the guide-arm, The guide-arm is then elevated upon releasing the treadle, returning to the position shown in Fig. 1, the finger p rising to allow the passage of the pin fl When operating on the next shoe of the pair, the guide-arm is again depressed at the desired time and the pin f turned a quarter of a revolution by striking and moving along upon the left beveled face of the finger p and then the rod 19 is pushed toward the left by the operator striking upon the knob 2 0 and during such movement the finger 9 hearing against the pin moves it suificiently for the latch f to again drop into engagement with the notched collar and the detent to will at such time be moved into engagement with the cut-away plate to. Thus it will be seen that the latch f is reversed each time it is depressed or caused to engage the notched collar. We do not desire, however, to limit our invention to this means of operating the latch f It will be observed that a cam constructed and arranged to be reversed, as herein de-v scribed, acts both to raise and lower the guide with relation to the knife; but we intend to include within the spirit and scope of our invention any equivalent device or devices by which the guide and knives may be moved one with relation to the other while trimming or trimming and channeling a sole, that the width of the projecting edge of the sole may be varied, and particularly any device or devices acting upon or in conjunc- ICC arm 19 bearing the pin and the arm 19 hearing a. pin and when the rod 19 is in proper position for the finger 10 to cooperate with the latch f the pin 19 bears against the support p; but whenever desired the rod 19 may be oscillated, the finger p moved out of cooperative relation with the latch f and at such time the pin 5 will bear against the support p.

henever it is desired to use the machine without the cam or its equivalent device, whereby the width of the projecting edge of the sole may be varied along the fore part and yet so trim the sole that it will project a greater distance beyond the last or inseam around the fore part than along the shank portion, the bevel-faced finger will be moved the pin on the latch f its full distance toward the right, and then the first time the last-guide is depressed will strike the left beveled face of the finger and be thereby turned a quarter of a revolution, at such time resting upon the upper end of the hearing. or

frame, and it will remain in such position until the rod 10 is positively moved by the operator striking the knob on the end of the rod, and hence whenever it is so desired to use the machine the operator permits the latch to continuously remain in this position.

The last-guide f is or may be made ad j ustable-as, for instance, it may be connected to the arm f by aset-screw passing through a slot cut in the part f, so that said part f may he raised or lowered, as desired, in order that the width of the projecting edge of the sole around the fore part may be more or less, as desired, although in such case such Width isthe same all around the fore part,yet greater than along the shank portion, and this adjustability of the last-guide also forms a part of our present invention.

The machine herein shown contains tri n1- ming and channeling knives and feeding mechanism for the work and a guiding device for the work movable freely toward and from the trimming and channeling knives during the trimming and channeling operation to vary the position of the boot or shoe with relation to said knives, and thereby vary the width of the projecting edge of the sole;

but/such feature is not herein claimed, as it forms the subject-matter of our application Serial No. 572,258.
