SPECIFICATION forming part of Letters Patent No. 665,245, dated January 1, 1901. Application filed January 11, 1896. eerial N6. 576,086. the model.)
To all whom it may concern:
Be itknown that I, THOMAS E.MAJoR,a citizen of the United States, residing at Maiden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Trimming the Edges of Upper-s within Shoes or Boots,of which the following is a specification.
It is desirable in the manufacture of certain kinds of shoes to remove therefrom a portion of the edge of the lasted upper, or of the upper and lining, after it has been attached to the outsole. In the manufacture of such a shoe a section of an insolenamely, the shank and heel end thereof-is mounted upon the bottom of a last, and there is also attached to the bottom of the last a dummy half-sole section narrower than the bottom of the last, which extends from the shank. end of the insole forward and includes the ball and toe. Upon these two sections, the first of which forms a permanent part-of the shoe and the second of which is used only for the purposes of lasting,the edges of the upper and the lining are attached in lasting and as though the two sections constituted an ordinary i11- sole. The lasted upper and the two-attached sole-sections are then removed from the last, and the upper is permanentlyunited to an outsole by a seam sewed by the McKay sole-sewing machine or a similar machine or by any other fastening means which pass through the edge of the upper within the shoe, close to the side thereof, and through the outsole, preferably into a channel in its undersurface. This uniting-seam extends through the rear part of the sole-section already referred to as forming a permanent part of the shoe; but it preferably passes beyond the outer edge of the dummy-section. The shoe thus made is then subjected to a further process by which the dummy-section and the overlapping edges of the upper and the lining, which were lasted upon it, are removed, the edge or surplus part of the upper and lining being severed from the main part of the upper and lining by means of a mechanism employing a rapidlyreciprocating knife adapted to be introduced within the fore part of the shoe and to cut the edge of the upper and lining close to and within the line of the uniting-seam, but outside of the edge of the dummy-piece, from one end thereof,about the toe, to the other end, or completely around it. The dummy-section and edges of the upper and lining may then be readily removed. My invention relates to machines adapted to thus out within the shoe or other inclosed or partially-inclosed space. Machines for doingthis were patented by G. W. Day November 24, 1891, which patents are numbered, respectively, 463,947 and 463,948, and my invention is an improvement in the class to which they belong.
My invention comprises an organization having, among other devices, first, a support or rest upon which the outsole of the shoe bears during the operation of a trimmingknife; second, a reciprocative cutter or knife above the said sole support or rest and a barcase and guide for the same, which bar-case and guide are adapted to be moved laterally from above the sole support or rest to a position at one side of the same to permit the placing of the shoe over the lower part thereof and its removal therefrom, the cutter, casing, guide, and shoe being movable together to and from the operative position of the cutter over the sole support or rest; third, a gage against which the edge of the sole of the shoe is adapted to be held and guided by the operator while the shoe-sole is upon the sole rest or support and during the operation of the trimming-cutter, which gage determines the line of the cutting action of the reciprocating cutter or knife in respect to the seam that unites the outsole to the upper or other predetermined line, and this gage when positively rotated may also act to assist the operator in the feeding or presentation of the shoe to the cuttinginstrument; fourth, means for actuating the cutter and for latching the knife-case and guide in operative position and for unlatching them to permit them and the knife to be moved laterally; fifth, means whereby the unlatching of said knife-bar case and guide also serves to automatically lift the knife or cutter in the case to its highest position or Within it, if the machine in coming to rest has not so lifted it, and for the purpose of preventing injury to the Work or the operator when moved laterally to its ini operative position or while it is being moved to and from such posit-ion; sixth, means for adjusting the sole support or rest vertically and horizontally and the sole-edge gage vertically and horizontally, whereby the relation of these parts to each other and the line of reciprocation of the knife orcutter may be varied at the will of the operator.
It will be understood that the shoe is presented to the machine and fed right side up, that the bottom or under surface of the outsole rests upon the sole-support with its edge bearing against the gage, that the knife or cutter is held within the shoe by its bar casing or guide, which is shaped at the lower end to so locate it, and that the under surface of the knife-bar case is not brought into contact with the upper surface of the lining or bottom of the shoe, but that there is a clear space generally between the under surface of the knife-bar case and the upper surface of the lining or bottom of the shoe. It will also be understood that the operator guides the shoe during the entire operation of the machine, whereby the above relation of the parts to each other during the entire cutting operation is maintained, and that where the gage is rotated it assists in that it helps to move the shoe.
Reference is to be had to the accompanying drawings forming part hereof, wherein Figure 1 is a view in side elevation of a ma chine embodying my invention. Fig. 2 is a view in plan thereof. Fig. 3 is a view in vertical section, on the line a: a: in Fig. 2, of the upper part of the machine. Fig. at is a view in horizontal section upon the dotted line 1 y in Fig. 3 and in plan of parts below said line. Fig. 5 is a view in front elevation, eularged, representing the knife case and devices for suspending it, locking it in operative position, and for operating the knife. Fig. (5 is a view in elevation, enlarged, of the parts represented in Fig. 5, showing them in full lines in different operative positions from those represented in Fig. 5 and in dotted lines removed laterally from said position and also representing, in connection with Fig. 5, the means for moving the knife to its highest position upon the unlatching of the knife case and guide. Fig. 7 is a detail view, in verticalsection enlarged, representing the relation of the boot or shoe to the sole-support, the sole-edge gage, or the knife or cutter when the work is in operative relation to the parts and the parts in operative relation to each other. Fig. 8 is a detail view, in horizontal section, upon the dotted line .2 z of Fig.
A indicates the stand or frame of the machine. It is generally made in two parts namely, the base a and the upper section ahaving at its top the forward extension a and at its back the bracket a shown as integral with section a. The extension (1, is hollow,and through it extends the main shaft B of the machine, which has suitable bearings therein and thereon. Means are provided for rotating shaft 13 and for quickly stopping its rotation. For this purpose the shaft B carries clutch members 1) b, the driving member I) of which clutch is also shown as a belt-wheel and which when disengaged from the driven member I) of the clutch revolves freely upon said shaft. The driving member I) also has limited endwise movement upon shaft B. The driven member I) of the clutch is rigidly attached to the shaft and is engaged by the driving member Z) when it is desired to operate the machine. The means I have shown for this purpose comprise rock lever b pivoted at b to the bracket (1 and connected with a foot-treadle B by a link or rod 17 the arm b of lever 1) being adapted to engage the driving member I). The depression of the treadle causes the driving member of the clutch to be moved into engagement with the driven member and to be held in such engagement by means of arm b and upon the release of the treadle a spring Z), connected therewith, draws the treadle up to remove the pressure of the rocklever b ,from the driving member. The rocklever 11* also has an arm carrying a brake or block N, which acts against the driven member I) of the clutch when the treadle is used to check the rotation of the shaft B after the clutch members Zr and Z) are disengaged.
The shaft B is used to actuate a cutter or knife, and for this purpose at the front end carries a crank-pin c, which is connected by a pitman or link 0 with a knife-bar e, located in a knife-case C, the knife-bar carrying a knife or cutterC'. As shaft Bis rotated rapidly and rapidly reciprocates the knifebar and knife, I have represented said shaft as provided with a counterbalance in opposed relation to the crank and knife-bar. The knife or cutter O is suitably secured to the bar 0. The knife-bar case 0 may be said to have, for convenience, ageneral shape, on a diminutive scale, like the lower half of a case made to lit a banjo, with a head 0 sharply bent back, held upright end for end, face out, with a cap and plate 0 covering the circular part and the upper half of the straight part and a plate e covering the lower half of the straight part, the part c being uncovered on the lower side. The knife bar case is movably supported, and for this purpose from the center of the circular part a sleeve 0 extends over the main shaft on which it is journalcd, the axis of the shaft B and the case C being concentric. c is a lug or car carried by the case 0, shown on top thereof, the lug or ear 0 having a latching-recess 0 which is adapted to receive a locking-pin (1, shown carried by a rocker-arm (l The pin d and lug or ear 0 serve to hold the case C either vertically or slightly inclined from the vertical, as will hereinafter appear, and thus serve as a lock for the case 0.
The circular and the straight part of case 0, as illustrated, form three recesses of different depths. The first incloses the counterbalance 0 carried by the main shaft, as well as the crank-pin c, and the sleeve or hearing of the pitman c journaled on it. The second recess is for the play of the pitman, and the third and shallowest recess is for the upper and longer portions of the knifebearing bar 0'. The part 0 forms a cover for the top and sides of the backwardly-projecting portion of the knife-bar 0, out from under which the bar reciprocates with the knife at its extremity and up and into which both are drawn when the device that raises the locking-pin from its recess rotates the main shaft, as hereinafter shown.
It will be seen that the knife-bar is bent at its lower end inwardly and downwardly, and thus carries the knife inside the shoe and there operates it. The bar may be reciprocated in any desired way. The knife-case acts when rigidly locked in a fixed position as a guide to maintain the knife bar or arm in its operative position of rapid reciprocating motion, and it also acts as a cover for said bar and as a means for moving said bar laterally, the bar a being pivotally supported by the crank'pin c.
The knife-bar case is represented in full lines in Figs. 5 and 6 in its latched position and in Fig. 6 in dotted lines in its nnlatched position. In Fig. 5 the locking-pin d is shown in engagement with the latching-recess c of the case, and in Fig. 6 it is represented as disengaged from the latching-recess to allow the case to be moved from the position shown by full lines to the position shown by dotted lines. The locking-pin 61 projects horizontally from the arm 01 and the latter is carried by a rock-shaft d. The rock-shaft d is supported by brackets 61, which project from the extension 0. (See Figs. 1, 2, and 5.) Rock-shaft d also carries an arm d that is connected with a treadle D by an arm D. The treadle D is held in its highest position by a spring (i and this serves to hold the locking-pin d in its lowest position or in a position to automaticallyen gage the latchingreeess 0 when the case 0 is moved from the position shown by dotted lines in Fig. 6 to the position shown by full lines in Fig. 5. The lug c is extended upward upon one side of the latching-recess to provide a stop beyond which the pin may not pass, and upon the opposite side of the latching-recess it has the inclined surface 0 which serves to lift the locking-pin to allow it to pass into recess 0 of lug 0 when the latter is moved from its lowest position to its normal operative position.
It is desirable to stop the rotation of shaft B as soon as it is disconnected from its driving devices, and for this purpose the shaft d also has an arm a, that carries a roll or pin E, which roll or pin is adapted to engage the edge e of a heart-shaped cam E, supported by shaft B and shown carried upon the front face of the driven clutch member I). When the treadle D is moved downwardly, it lifts locking-pin d from the recess 0 of lug c and simultaneously brings roll E into engagement with cam E, thereby turning the shaft B sufficiently to operate the crank-pin and cause it to lift the knife-bar and the knife C totheirhighest position, unless, of course,- the machine shall have stopped when the crank is in such position. The edge of the heartoam has a return-curve, forming a recess 6 which permits the said roll or pin E to make its full stroke either when the roll or pin acts to move the cam or when the cam has stopped with the said recess in line with the said roll or pin. It will thus be seen that the opera= tion of unlatching the knife-bar case preparatory to the removal of the shoe therefrom automatically causes the shaft and crank-pin to be turned, if the crank-pin is not already in its highest position, to lift the knife from the shoe into the lower end of the knife-bar case, thereby permitting the shoe to be removed without injury to itself or to the knife and permitting the placing of a new shoe upon the lower end of the knife-bar case without injuring the knife or shoe.
It will be understood that the shaft may be turned by the cam and its actuating-pin, because at that time the shaft is at rest, the driving member of the clutch having been disengaged from the driven member. The heart-cam E may be attached directly to the shaft B instead of to the driven member of the clutch.
Beneath the knife or cutter O is a support or rest for the outsole. Such a support is shown at F and which is indicated as inclined from its upper endfdownwardly and outwardly, and it also preferably broadens from its upper end. The support or rest F is adjustable vertically, and forthis purpose it is shown extending to the upper end of a slide f, which is movable for the purposes of adjustment in a vertical slidewayf' at the front end of a horizontal bracket F, which slideway is preferably formed in the end of the bracket. The slide is so represented, and it is covered by a cap-plate f The meansI have shown for allowing vertical adjustment of the slide and the sole-support comprise an adjusting-screwf having a head f which screw meshes in a threaded hole in the cap plate f the outer edge of which head enters a recess f extending across the face of the slide f near its lower end. The slide extends below the bracket and cap in order to permit the engagement of the screw-head therewith and also for the purpose of locating the head of the screw in an accessible position. A set or look screw f is carried by the bracket F and is adapted to be screwed against the slide to fasten it and the sole support or rest in a stationary position after they have been adjusted. The bracket F is adjust-ably attached to the section a of the main frame, being shown so attached by a screw-stud f which passes through a slot f in the bracket, and by means of this slotand the screw the bracket is enabled to be adj usted horizontally, which provides horizontal adjustments for the sole rest or support. The inner end of the bracket is squared to fit a squared horizontal recess in the side of the frame, (indicated by dotted lines in Fig. 3,) although it may be otherwise supported thereon. To assist the operator in guiding the shoe under the knife, I have shown a gage adjacent to the shoe-support. The gage H is located back of the sole support or rest and somewhat above it,and it serves asa means for determining the line of action or cut of the reciprocating knife or cutter c in the shoe or article which may be held against it. It may be a stationary gage, or it may be provided with rotation, in which event it becomes a feeding or antifriction gage, and when it is so employed I prefer to rotate it by means of a spirally-threaded wheel h on a shaft hand a spirally-threaded wheel 72*, the axis of which is at a right angle to the axis of the firstnamed wheel and which is carried at the end of a hollow horizontal shaft h (See Figs. 1 and 4.) The said shaft h3 is supported at one end by a stud attached to a bracket 7L4 and at the other end by the bracket 72. and said shaft has a beveled gear lbs, with which a beveled gear h at the lower end of a shaft 7L7 engages. This shaft 71.7 is in turn connected with the main shaft B by means of a worm-wheel 7&9 at the upper end of shaft h meshing with a worm h upon the main shaft. (See Fig. 2.) Shaft IL7 is journaled in suitable bearings carried by the main frame. The gearing is of a size to provide the gage with relatively slow rotation. The gage is provided with means whereby it may be vertically and horizon tally adjustable in relation to the sole support or rest F. It is vertically adjusted by means of a sleeve m, through which the shaft It extends, which sleeve has an exterior screw-thread m, screwing into a threaded hole m at the forward end of a slide m The sleeve m has an enlarged section or head M, by which it may be turned. It will thus be seen that the support F and gage H are supported and adjustable independently of each other, and it is evident that a skilful operator could guide a shoe on the support F under the knife without utilizing the gage H as a guide.
It will be understood that the sleeve m furnishes a bearing for the gage-shaft h and that it also provides means whereby the gage-shaft and gage may be vertically adjusted. That this adjustment may be made without disengaging the threaded wheels h 7L2 the threaded wheel h is made longer than would otherwise be necessary. A stud m extends through an opening in the slide m and bears constantly against the outer surface of the sleeve m. It is pushed inward by a lever or arm at, pivoted at m and against which a spring m bears, so that the stud m is forced and held by the yielding pressure of the spring against the sleeve.
The slide m has a round section m which slides and is held in opposed holes 127. in the frame A, and means are provided for adjusting the slide horizontally toward and from the sole-rest F. For this purpose I have shown an adj usting-screw m fastened to the frame A and extending outward therefrom, and an adj usting-nut m mounted upon said screw m and which engages the slide m by means of a forked connecting-arm m extending therefrom.
To permit the horizontal movement of the gage without disengaging the threaded connecting-wheels h h the wheel 7L2 upon the horizontal shaft is made longer than would otherwise be required. The bevel-gear h ,the threaded wheel h and their operating-shaft may be covered by a curved cover-plate n.
It will be understood that when the gage H is not adapted to have rotary movement the operating-wheels h 72. and shafts 7L3 h and their connecting-gearing may be dispensed with.
The operation is as follows: The knife-bar case having been moved to oneside of the shoesupport, theshoe is placed over the end of said case and is then moved with the knife-bar case over the work support or rest, whereupon the knife-bar case is automatically locked and maintained locked with the knife-bar and knife in operative position within the shoe. The shoe-sole thus resting upon the sole-support its edge is brought in contact with the gage, and this causes the inner surface of the sole and the edge of the upper to be separated from the under surface of the knife-bar case. The machine is then set in operation and the shoe is fed andguided by the operator in a manner to cause it to be presented in any desired order of movement to the action of the cutter, which is rapidly reciprocating within the cavity of the shoe, and by adjusting the gage to any desired position and holding the edge of the sole in contact therewith the line of the cut made by the knife may be predetermined. When a rotating gage is employed, the edge of the sole is advanced by the gage, as well as located by it, so that the following sections or parts of the sole edge are to adegree automatically gaged.
It is desirable that the knife be centrally located in respect to the sole-support and the gage. Nice fitting of parts would be necessary to so locate the knife were it not that means are provided whereby it may be more readily accomplished. This result is obtained by making the locking-pin (1 upon the arm 01 of the rock-shaft adjustable lengthwise upon the arm, and a change in its position on the arm will of course vary the position of the lower end of the knife-bar case of the knife. Any means for adjusting the pin horizontally may be employed, and I have represented as one means a longitudinal slot in the said arm d in which said pin is horizontally movable, the pin being locked to the arm in any desired place by a washer and nut.
I may say that the apparatus herein described may be used for trimming out an ysurface material from tlie'interior of a shoe or other hollow article and that the details of construction shown and described may be varied Without departing from the spirit of my invention.
