METHOD OF AND MACHINE FOR MARKING SHOE-UPPERS.

Application filed December 28, 1915.

T 0 all whom it may concern:

Be it known that I, I'IERBERT E. ENSLIN, a citizen of the United States, residing at Maiden, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Methods of and Machines for Marking Shoe-Uppers, of which the following description, in connection With the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

The present invention relates to the art of marking shoe uppers and is more especially directed to improved methods and mechanism for marking shoe uppers for buttons and buttonholes.

It has been proposed to mark the locations of the buttons and buttonholes on the quarters and flies bcfore the parts of the upper are finished and stitched together. In this method of manufacture, it is possible that the button and buttonhole locations may not aline when the fly and quarters are stitched together and overlapped, because of inaccuracy in the lines of junction of the parts.

It has also been proposed to mark the fly for buttonholes by a hand marking implement operating through a pattern plate or stencil, to cut and finish the buttonhole and stitch the fly and quarters together, then to fold the upper with the quarter and fly properly overlapped and to mark the button locations on the button quarter in line with the eye ends of the buttonholes by a hand tool inserted through the buttonholes in the superposed buttonhole fly. This hand operation, however, is slow and has the added disadvantage of failing to allow for the tipping or overlay of the buttons due to the play of the button eye in its fastening. Such an allowance should be made in marking so that when the shoe is buttoned, the edge of thebutton quarter will be maintained exactly beneath the center seam which constitutes the line of crimping or folding of the upper.

In one of its aspects, the invention comprises a method of marking button locations which is characterized by uniting the fly and quarters of the upper, folding them in properly overlapped relation, utilizing the ends of the buttonhole locations on the overlying fly as guides and marking the under- Specification of Letters Patent.

lying button quarter at points spaced length- Wise from said ends to indicate the points for the subsequent attachment of the but tons.

In a related aspect, the invention includes a method of marking button locations onthe quarter of a folded united upper in which the buttonholes have been formed which is characterized by the marking of the button locations on the button quarter at points offset from the eye ends of the corresponding buttonholes in the overlying fly in the direction of length of the buttonholes and which, as practised by the illustrated machine, consists in positioning a marking element between the fly and quarter in line with and offset from the buttonhole location, as described, and operating upon the fly to actuate the marking medium. Conveniently, when the buttonholes have been previously formed in the fly the marking medium may be operated through the buttonhole in the overlying fly.

The invention also includes within its scope novel mechanism with the aid of which these novel methods may be carried out in a convenient manner, although the machine may be used in the practice of other methods than those herein disclosed, while the methods described may be carried out by the use of machines or apparatus of many different types as will be apparent to those skilled in the art.

One feature of the machine consists in intermittently and automatically operated buttonhole location marking means, with means for feeding the stock to said marking means intermittently and alternately with the marking operations.

Another feature of the invention resides in mechanism constructed and arranged to mark on the folded upper the locations of buttons and buttonholes substantially simultaneously and for a number of successive buttons and buttonholes, including llltQllTllttently and automatically operated means to mark the button and buttonhole locations, with means for automatically feeding the folded upper to the marking means, intermittently and alternately with the marking operations.

A further feature of the invention consists in certain mechanism for marking the fly and button quarter of a folded upper substantially simultaneously and at relatively ofl'set points to indicate the buttonhole and button locations, and with means for supporting the folded upper in marking position. 7

Additionally, a feature of the invention consists in mechanism for marking button and buttonhole locations on folded shoe upper substantially simultaneously including button and buttonhole marking instrumentalities cooperating with work gaging and guiding means and constructed and arranged for one adjustment to mark buttonhole locations on a separate fly, and for further adjustment to mark button locations on the button quarterof the folded upper having the same fly attached with the buttonholes formed therein.

So far as I am aware the machine of my invention is the first machine devised and constructed to mark button or buttonhole locations, or both, having intermittently and automatically operated marking means, with means for automatically feeding the stock to the marking means intermittently and alternately with the marking operations.

Another feature of the invention consists in the combination with power operated instrumentalities for intermittently operating on the work to mark the work and for intermittently and alternately feeding the workto the marking instrumentality, of controlling mechanism arranged to stop the operation of said instrumentalities at the end of a selectively predetermined number of successive operations. From this viewpoint, the marking or locating feature of the invention may have a wide range of equivalents and may include marking by perforation or cutting as well as marking by imprinting or coloring. With such a combination the locations of a selected number of buttons, buttonholes, eyelets, etc., may be automatically marked. In the illustrated embodiment, the operation of the marking and feeding means is controlled by a starting and stopping mechanism arranged to rotate a driving shaft a selected number of revolutions or work cycles and to stop automatically the operation of the machine at the end of the selected number of cycles.

Another feature of the invention relates to novel mechanism constructed and arranged to mark uniformly buttonhole locations on the upper at a predetermined angle to the edge of the fly. As illustrated herein, a

buttonhole marking element of the outline of a buttonhole is guided for marking operation so that it extends substantially at right angles to a fly'edge guide against which the edge of the work is held during the marking operation.

A further feature of the invention consists in the combination with intermittently operated marking mechanism, of intermittently operated work feeding mechanism constructed for reverse directions of feed.

This feature is particularly advantageous in marking shoe uppers where right and left parts may befed to the marking mechanism from opposite directions. The work feed 7 ing mechanism includes in addition, certain In a step by step machine of the typein volved in the present invention, when used for placing location marks at uniform distances from the edge of the stock, and especially stock havingv curved edges, it is important that the direction of feed of the stock to the marking instrumentality is such as to insure such uniform marking. Accordingly, a feature of the invention re-' sides in a plurality of spaced gage members against which and by which it is guided during the feeding operation to position properly the the stock relatively to the marker. By having two contact points as guides the line of feed is fixed and accuracy is assured.

Another feature of my invention consists in the combination with an intermittently operated marking element of means for ap plying a coating of marking material to the marker prior to each marking operation. In the illustrated embodiment of the invention a reciprocating marking element is employed, and a. color applying device is reciprocated transversely of the path of reciprocation of the marker to engage the marker and apply color thereto prior to marking movement of the element. These, and other features of the invention are more fully described in the following specification and are illustrated in the accompanying drawings, in which Figure 1 is a view in end elevation of a machine illustrating one embodiment of my invention, parts of the machine being shown in section to disclose interior mechanism;

The marking machine has a hollow base 2 with a hollow upstanding head 4 overhanging the base and having its front end closed by a removable face plate 6. A driven shaft 8 is journaled in this head and extends substantially parallel to a second driven shaft 10 journaled in the base 2. A bracket 12 extending rearwardly and downwardly from the head 4 supports one end of a driving shaft 14, the other end of which is mounted in the rear of the base 2, this shaft being substantially parallel with the shaft 8 in the machine head. A driving pulley 16 is loosely mounted upon the outer end of the shaft 14 and is arranged to be continuously driven by suitable belting. Upon its inner face the pulley is provided with a clutch socket 18 designed to receive and rotate a part projected from a member fastened to the driving shaft.

This member may take the form of a sleeve 20 fixed to the shaft 14 at the rear of the base and having an enlarged threaded collar 22 positioned on the shaft in juxtaposition to the inner face of the pulley 16.

The threads of this sleeve enlargement will be of predetermined pitch and number for cooperation with selective revolution governing mechanism, hereinafter described. The sleeve 20 and its enlargement 22 contain a longitudinal bore in which is mounted for sliding movement a spring pressed locking pin 24 normally tending to move in a direction to enter into the socket 18 of the continuously rotating pulley 16. This pin 24 carries a transversely extending head 26 guiding in a slot formed in the sleeve 22 and extending longitudinally thereof.

The forward end of the shaft 14 carries a sprocket wheel 28 connected by a chain 30 with a similar sprocket wheel 32 mounted upon the shaft 8 in the machine head to retate said shaftat the same speed. Adjacent this sprocket the shaft carries an eccentric 34 with an arm 36 extending from the eccentric strap and pivotally connected to the end of a crank arm 38 secured to the rear end of shaft 10 in the machine base. When the shaft 8 is rotated the shaft 10 is rocked or oscillated to operate certain stock feeding mechanism hereinafter described.

At its forward end the head 4 of the machine is enlarged and extends downwardly toward the base 2. The forward end of the shaft 8 extends within the upper end of this enlargement and has fixed thereto a disk 40 formed with a peripheral cam groove 42. The outer face of this disk carries an eccentric pin 44 to which one end of a link 46 is pivotally connected, the other and upper end of the link being pivotally connected to clamp member 48 holding and reciprocating a plunger 50, whose upper and lower ends are guided in the upper and lower portions of the head 4 of the machine.

The lower end of the plunger 50 is hollow and contains a coiled spring 52 operating against a plunger foot 54 guided for movement in a predetermined direction relative to the plunger 50 by means of a pin 56 in the plunger cooperating with a vertical slot 58 in the plunger foot. The plunger itself is guided and prevented from turning by a pin 57 in the head 4 extending into a slot 59 in the upper end of the plunger. The lower end of the foot 54., as shown, is of substantially reduced diameter and has clamped thereto a removable marker 60 whose marking base 62 may be shaped to correspond with the outline of the part to be cut out or worked. In the illustrated machine, the marking portion 62 is shown as outlining a buttonhole, the projecting end of the foot 54 forming the eye, and is especially designed to mark buttonhole locations upon the flies of Shoe uppers.

The markers 62 may be of any desired type. For instance, in order to provide a mark which is clearly discernible upon all types of upper material, it is desirable to employ a marker which applies a colored mark to the stock. Accordingly, an arm 64 is pivoted to the machine head at 66 and has its upper end provided with a roller 68 which is guided in the cam groove 42 of the disk 40. The lower portion of the arm is offset, a at 70, and thence extends downwardly toward the bed 2 of the machine, as at 72 (Figs. 1 and 2). Its lower end is forked to embrace the pin 74 of a reciproeatory ink pad carrier 76 moving transversely of the line of reciprocation of the plunger 50 and preferably guided by spaced edge guides 78 (Figs. 1 and 3) carried by spaced arms 79 depending from the head 4 and having longitudinal grooves 791 in their side faces into which the flanged edges of the carrier 76 extend. Through the cam 40, the arm 64 will be rocked to slide the ink pad carrier 7 6 to and fro on its edge guides in a direction transversely of the line of movement of the plunger carried marker 62. This operation is timed to occur when the plunger 50 has been moved to the upward limit of its stroke, so that the marker is inked prior to each marking movement.

At its base the downwardly projecting portion of the forward end of the machine head is formed with a socket 80 in which is adjustably mounted a vertical rod 82. This rod extends down to a point adjacent the top of the machine bed and is provided with an enlargement 84 (Fig. 5). Extending laterally from this enlargement and detachably secured thereto by the screw 86, is a combined stock edge gage and marker. This device may take the form of an elon gated member 88 having a relatively flat stock guiding face 90.

When the device is to be used for guiding the edges of stock of curved outline, such-as buttonhole flies, this face 90 will preferably be concaved to correspond substantially with the average curvature of buttonhole flies. The guide surface 90, when vertically positioned to cooperate with the work edge, is spaced laterally a predetermined distance from the adjacent end of marker 62 so that the location marks will be uniformly spaced from the edge of the material. The marker 62 will extend at a determinate angle to the longitudinal gaging line of surface 90, this angle being predetermined by the adjustment of the marking base 62 about the stem formed by the reduced lower end of the plunger foot 54, this plunger being held against axial turning movement by the pin 56 and slot 58 and the marker being held in angularly adjusted position on the lower end of this plunger by a set screw as shown (Fig. 4).

At the face opposite the guiding surface 90, the member 88 is formed with a flat base 92 whose edge 94 forms a second stock edge guiding face which, when the parts are adjusted to the position shown in Fig. 4, is positioned in a vertical plane to guide the edge of the buttonhole fly similarly to the guide surface 90 in Fig. 1. The lower edge of the vertically disposed guide face 94 is, however, elevated a greater distance above the work supporting feed wheel than the corresponding edge of guide surface 90, so that the guide face 94 is elevated to a horizontal plane corresponding to the plane of the overlying buttonhole fly on the united upper. Guide surface 90 is utilized, of course, for guiding the edges of buttonhole flies before they are stitched to theother parts of the upper. Secured to the under face of the plate 92 by a suitable clamping screw, is a spring blade 96 whose outer end is bent upwardly (Fig. 6) and is positioned in the line of movement of the plunger actuated marker 62. The under face of the upwardly bent portion of the plate 96 carries a prick point 98 positioned at a point slightly beyond the eye end 54 of the buttonhole marker in the direction of the edge of the buttonhole fly (see Fig. 4).

The length of the plunger stroke issuch as to apply suflicient pressure either directly or through intervening substance, to the spring blade 96 so as to straighten out the spring bend in the blade and to force said blade downwardly to cause this prick point to mark the substance beneath the blade. When the plunger is raised, the spring of the bend in blade 96 will lift up thefront end of the blade so that the material can be fed without interference by the prick point 98. By one adjustment, thereactuated by the first marker to mark underlying portions of folded materials between which it is positioned. In order to permit this adjustment of the member 88, the'bed 2 of the machine is cupped out, as at 100, Fig. 1.

The stock is intermittently fed toward the marking devices described alternately with the marking movements of the plunger 50 and for certain predetermined distances. One desirable form of mechanism for effecting this result includes a feed wheel 102 loosely mounted upon the rock shaft 10 and having the outer portion of its periphery roughened to grip the stock. of sufficient breadth to extend beneath the marking devices to act as an anvil for the markers and to receive the pressure from certain presser devices operating upon the upper face of the stock and thereby effectlvely to grip and feed the stock. This feed wheel extends above the surface of the bed plate 2 sufficiently to insure contact with workplaced upon the base.

At the outer face of the feed wheel are complemental oppositely toothed annular ratchet surfaces preferably in the form of wheels 104, 106 for rotating the feed wheel in opposite directions. The shaft 10 extends beyond the feed wheel and ratchet wheels and carries at a point beyond the ratchet wheels a double armed lever 108 to whose opposite ends are pivoted spring pressed driving dogs 110, 112 overlying and normally tending to engage the teeth of the ratchet wheels 104', 106' respectively. The ends of the arms 108 carrying the driving dogs extend out through an annular slot 114 formed in the outer face of a ratchet-inclosing shield 116 of annular form. t

This shield is carried by a sleeve 120 which, in turn, is fixed to a second inner sleeve 122 forming a housing for the reduced outer end of the rock shaft ,10 and itself enlarged at its outer end to form an operating knob 124 with a laterally extending arm 126 positioned at the outer face of the base 2. Rotation of the knob 124 will, therefore, rotate the ratchet shield 116.

The driving dogs 110, 112 are offset from the extended ends of the arms 108 to overlie their respective ratchet wheels and normallytend to engage these ratchet wheels. The shield 116 covers the toothed peripheries of both ratchet wheels, except for those portions of the ratchet wheels exposed be tween the spaced ends 118 (Fig. 2'). of the shield, which ends are beveled downwardly toward the ratchet teeth so as to cause the endsof the driving dogs to ride up on the The wheel is shield when they are moved in the direction of the shield edge and into contact therewith. The range of movement of the dogs is fixed by the predetermined rocking movement of the shaft. As these dogs are in opposed relation only one driving dog may engage a ratchet wheel in any one operative position of the shield 116, as the opening in the shield extends for only a relatively short portion of the periphery of the shield and is designed to represent the maximum length of a single feeding movement of the feed wheel. Since the crank arm 38 swings both upwardly and downwardly with each revolution of driven shaft 10, the double armed lever 108 will swing equal distances in reverse directions during each revolution. Only one of the driving dogs 110, 112 can engage its ratchet through the shield opening during these two swinging movements of lever 108, the other driving dog riding idly over the closed peripheral portion of the shield.

By varying the position of the shield opening relatively to the field of movement of the operative driving dog, the effective length of the driving stroke of the dog may be varied at will. By reversing the position of the shield opening through the knob 124, the opposite and formerly inoperative driving dog is permitted to operate through the shield opening to rotate its oppositely toothed ratchet wheel and the feed wheel in the reverse direction for reversing the direction of feed of the stock, while the formerly active driving dog is guided up on to the outer peripheral face of the shield and rides idly over its closed peripheral face portion out of engagement with its ratchet wheel. The arm 126 of knob 124. affords means for holding the shield in different selected positions of ,feed control to vary determinately the direction of feed and the extent of feeding movement of the ratchets, so that the amount \of stock fed between successive marking movements will be not only uniform as to one adjustment, but may be varied to suit the requirements of different cases.

Accordingly, the outer edge of the base 1 at points opposite the knob 124 is provided with segmental plates 128 having a series of apertures therein with adjacent descriptive data giving the length of feeding movement afforded by each adjustment. The end of the arm 126 carries a pivoted spring pressed latch 130 having a pin which normally tends to engage in the adjustment holes in the plates 128 to maintain the shield in the position selected for adjustment.

At the front of the machine head a presser head 132 is guided for reciprocating movement toward and from the feed roll 102 and is normally pressed toward the feed roll by a coiled spring 13 1 operating against the head at one end and at the other end engaging an abutment 136 at the rear of the face plate (5. The face plate is slotted at 138 (Fig. 3) and a pin 140 attached to the presser head extends outwardly for engage ment by the edge of a lifting lever 142 which is pivoted upon the outer face of the face plate (3. The spring 134 normally holds the pin 110 at the lower end of the slot and against the edge of the lever which is held by gravity in engagement with the pin. \Vhen the lever is pressed down to lift the presser head and its attached parts, the pin 140 will ride along the edge of the lever and snap into the notch 1 13 in its end, looking the lever and head against further mvement and permitting the operator to use both hands in positioning the upper.

The head 132 at its lower end carries a conical presser roll 14:4 positioned directly above the roughened periphery of the feed wheel and cooperating with the feed Wheel and with the work to feed that portion of the work inwardly of the presser wheel more rapidly than that portion of the work at the outer edge of the presser wheel, thereby imparting a turning or swinging movement to the work.

Depending from the opposite sides of the presser head are complcmental spring presser arms 146 arranged to engage the upper face of the work at opposite sides and in line with the marker 62 to prevent wrinkling or puckering of the work when operated upon by the marker. These spring presser arms carry integral inward extensions 148 to which are adjustably secured combined stock edge guide arms and work end gages 150. The arms 150 are provided with curved flanges 152, forn'iing stock edge guides cooperating with the eentral guide surfaces 90, and 94, the end of these flanges adjacent the marker constituting a visual end gage for initially positioning the end of the work relatively to the marker.

This construction is particularly advantageous when used in guiding the edge of buttonhole flies, either alone or as part of a folded shoe upper. One guide flange 152 will engage the edge of the buttonholc fly in cooperation with the central guide 90 or 94, while the inner end of the eomplemental flange 152 will act as a visual guide for positioning the end of the buttonhole fly a predetermined distance from the buttonhole marking point. The distance of the first buttonhole from the end of the buttonhole fly is the same for all shoes in a large proportion of factories but the practice in this respect is not uniform. In order to provide for variance in the first buttonhole position, the arms 150 are slotted and may be moved relatively to the end of the arms 148 and fixed in adjusted position by means of screws or other desirable clamping devices.

as shown, the arms 148, 150 will Preferably, f ilitate bear suitable indication marks to accurate adjustment.

When the lever 142 is operated the presser wheel with the presser arms and edge gages chine which is particularly adapted for marking buttonhole flies and button quarters underwidely varying conditions of manufacture. In some factories the button fly is marked'fo'r the buttonholes and these buttonholes are worked in the fly before the latter is stitched to the quarter and the upper folded. Subsequently, the quarter is marked for the buttons through the buttonholes in the superposed buttonhole fly. The machine of this invention is adapted by slight adjustment to accomplish both of these marking operations and is also adapted to mark both the buttonhole locations and the button locations substantially si- ,multaneously upon the folded upper.

To mark the buttonhole fly alone, the work feeding mechanism is first adjusted to give the desiredspacihg between the marks and then the fly is inserted and its edge positioned against the guiding instrumentalities and relatively to the gaging means, as described. The machine is then started by operating a clutch, and through mechanism hereinafter described is operated through the number of work cycles corresponding to the number of marking operations de' sired, and is then automatically stopped. The position of the parts for marking the buttonhole .fly separately is indicated in Fig. 1. 7 f f When the fly has been operated upon to form the buttonholes and is then subsequently stitched to'the quarters of the upper and the upper folded so that the parts are properly overlapped, it may be operated upon by the same machine to mark the button locations on the quarter by adjusting the gage member 88 to the position indicated in Figs. 2, 4 and 5. The lever 142 is operated to lift the presser head with its attached parts and the upper is inserted beneath the marking instrumentalities, the spring blade 96- entering between the button fly and the quarter, and the edge of the button fly resting against the edge guide 94 and the appropriate edge guide 152; The feed is adjusted to correspond with that by means of which the buttonhole locations in the ,fly were originally marked, and the machine is started'as heretofore described. The.

buttonhole'marker 62 is preferably detached andthe foot 54 will operate through the successlve buttonholes to depress the sprlng blade 96 and mark the button locations on place the colored outline of the buttonhole upon the fly and will at the same time, by pressure transmitted to the spring blade 96 through the fly, cause the prick point of that blade to markthe button location on the underlying quarter at a point offset from theend of the buttonhole inthe direction of length of the buttonhole. As the plunger is lifted up thespring blade'96 will rise to lift its prick point clear of the quarter and permitthe feeding movement of the upper for the next marking operation.-

In all marking operations, the operator, after initially positioning the work,is only required to press the button fly inwardly against the edge gages for the fly and to maintain it in engagement with these guiding means. The feeding mechanism and the guiding means will maintain the proper direction of feed and the fly will be guided in the proper path of movement so long as its fly edge is maintained in engagemcntwith these guiding surfaces.

The number of marking operations will vary with different sizes and styles of uppers or upper stock. A mechanism adapted to automatically operate the driving shaft to give a predetermined and selected number of marking movements to the mechanism will be a great desideratum. Accordingly, I have provided a mechanism arranged for adjustment to rotate the driving shaft 14 a selected or predetermined number of revolutions and thereby to operate the driven shaft 8 and rock shaftlO for a 'selected number of work cycles.

One embodiment of such a mechanism which may be advantageously used in this connection includes a vertically movable bar 154 bifurcated to partially embrace the sleeve 20 on the driving shaft 14,. one arm of the bifurcation being provided with a cam face 156 terminating at its lower end in a socket 158. j The cam face isformed to engage the head 26' of the clutch pin to retract the pin from engagement with the continuously r'ota.tingpu1ley 16, the head of the pin being retractedtand finally seating in the socket 158 of this arm which acts as an abutment to stop further rotation of the sleeve 20.

The opposite arm 160 of the bar is extended upwardly above the sleeve 20 and into and through a socket 162 formed in the bracket 12 at the rear of the machine head. The upper portion of the bar is reduced in diameter to form a stem 164 which projects beyond and above the bracket 12 and carries an adjustable stop or abutment 166 at its upper end. Between this abutment and the face of the bracket 12 a coiled spring 168 is or other suitable means (not shown). The

rod 170 is guided in a bracket 172 at the base of the machine and is slotted at its upper end to house a pivoted trigger 174, the lower end of which is normally spring pressed outwardly to engage in a notch 17 6 formed in the edge of the bar 154 near its lower end. The upper end of the trigger is formed with a beveled face 178 which engages the edge of the bracket 172 after the bar 154 has been pulled down sufliciently far to release the clutch pin and permit the sleeves 20, 22 to be clutched to the rotating pulley 16.

When the bar has been depressed to this extent the beveled face of the trigger will engage the side of the bracket 172 and the lower end of the trigger will be thereby forced from engagement with the edge of the notch 176, releasing the bar 154 which under the influence of the spring 164 would normally tend to return into the plane of revolution of the head 26 of the clutch pin and would, under ordinary circumstances, cooperate with the pin head and retract the clutch pin at the end of one revolution of the driven shaft 14, the head of the clutch pin and the driven shaft being stopped when this head reaches the socket 158, the bar 154 and its spring 168 acting as a cushioning abutment. I have, however, provided means for preventing the automatic retraction of the clutch pin until the driven shaft has been operated for a definite and selected number of revolutions.

Accordingly, in the illustrated embodiment, the bar 160 at a point above the sleeve 20, has an offset 180 channeled in its upper face to provide a guideway 181 whose face is slightly curved. Sliding lengthwise in this guideway is a latch-releasing bar 182 having its forward end slotted and guiding upon a pin in the lower portion of the head 4 of the machine frame which is provided with an opening,at this point to receive the end of the latch releasing bar. The arm 160 of the clutch pin retracting arm 154 is formed with a socket 184 therein at a point above the bar 182 and with a slot 186 extending longitudinally of the arm and entering laterally upon the socket. Guided in this slot for vertical movement toward and from the latch-releasing bar 182 is a block 188 carrying an outwardly extending pin 189 arranged to engage the upper edge of the bar 182 and having spaced washers thereon embracing the opposite sides of the bar.

A spring pressed plu r 190 is seated in the socket 184 and norma 1y operates against the block 188 to hold the pin 189 pressed against the bar 182. At one side of the arm 160 an abutment piece 192 is provided, this abutment cooperating with a latch block 194 carried by a spring pressed latching lever 196 pivoted to the bracket 12. When the treadle rod 170 is operated to pull the bar 154 with its arm 160 downwardly to release the clutch pin the upper edge of the abutment piece 192 will be brought below the lower edge of the latching plate 194 which will be immediately snapped over the upper edge of abutment piece 192 by its spring and will prevent the return of the bar 154 to clutch pin retracting position until the latching lever 196 is moved to the left to place its latching block 194 out of the path of upward movement of the abutment 192.

In order to effect this release of the latching lever 196 to cause automatic retraction of the latch pin and the consequent stopping of the driving shaft 14 at the end of the predetermined number of revolutions, the end of the latch-releasing bar 182 is provided with a downwardly extending tooth 198 arranged to engage in one of the threads of the sleeve 22 when the bar 154 is pulled downwardly and latched. When this action takes place the tooth 198 will be held yieldingly against the threads of the rotating sleeve 22 by reason of the spring pressure exerted against the bar 182 by the pin 189. During the rotation of the sleeve 22 the bar 182 will be fed by the threads of the sleeve toward the left (Fig. 1) until a pin 200 carried by the bar engages the lower end of the lever 196 and moves its latch block 194 out of the path of upward movement of the abutment 192.

The pitch of the threads 22 and the position of the releasing pin 200 are in a definite ratio. For instance, if the tooth 198 were positioned to drop in the first thread at the left of the sleeve 22 (Fig. 1) and the bar 154 were ulled downwardly through the treadle and latched through the action will take of the parts 192, 194, the pin 200'would be positioned against the edge of the latch lever 196. and T one revolution of the threaded sleeve 22 would move the lever 96 a suiiicient distance to release the abutment 188, where upon the spring 164 would move the bar 154 upwardly to bring its cam face 156 in thepath ofthe head of the clutch pin, to retract the clutch pin at the end of the second revolution. a e

v .In order to secure a single revolution with the clutch pinautomatically withdrawn at the end of the revolution, the heel'o-f the lever 196 can be held upwardly ,by hand, holding the latch block 194 out of the path of movement of the abutment 192, so that the ordinary one cycle action of the clutch lace.

7 To position thetooth 198 for engagement vwith different threads, a flange 202 or an equivalent bracket is provided at the rear of the machine head and is formed with a raised plate 204 having a series of location apertures 206 formed in :the face. of the plate.- A shifting lever 208 is pivoted between its ends on the horizontal portion of the bracket 12 and has its lower end bifurcated and in sliding engagement with a pin at the rear end of the unlatching bar 182. The upperxend of the lever 208 is flattened and formed as a finger 210 normally pressed toward the left (Fig. 1) by a spring'press'ed plunger 212 mounted in the bracket 12 and bearing against the lever 208 at a point between its pivot and its upper end. p

A gage pin 214 may be placed in anyof the apertures 206 corresponding to the number of revolutions which it is desired the machine shall be operated and the lever 208 automatically swings its upper end to engage the gage pin 214 and at the same time, swings its lower end to position the tooth 198 over the thread groove in the sleeve 22 corresponding with the number of revolutions indicated by the selected aperture 206. These apertures will mark the position which the finger 210 of the adjusting lever should bear to bring the tooth 198 immediately above the thread groove for the number of revolutions indicated by the specific aperture. The number of revolutions may be varied to suit different conditions of the use of the machine, the pitch of the threads may be varied in specific cases and other changes may be made to suit varying conditions of work. The specific construction of this selective revolution clutch controlling mechanism forms no part of the present invention'but has been selected asa representative type of control adapted particularly'to a machine of the type involved in the present invention. With the described machine organization, the feed adjustment is first made then the selective revolution clutch'control adjusted and the work positioned for the first markingoperation. The treadle is operated to pull the treadle rod 170 downwardly, releasing the clutch pin and causing the shaft 14 torevolve. At the initiation of the cycle of operations, the parts will be in-the positions shown in Fig. 1 of the drawings with the operative feed dog 110, at the forward limit of its feeding stroke and the inking pad 7 6 in contact with marker 62. As soon as the rotation of shaft 14 begins, the shaft 8 will be rotated through the connecting chain and sprockets. Thereupon the inking pad 7 6 will withdraw from theyieldingly.pressed marker 62, and simultaneously, the operative feed dog 110 will begin to slide to the rear for the initiation of a feeding stroke. After the pad 76 has cleared the marker 62, the plunger 50 with the marker will begin, a downward work marking stroke which-will be completed when the feed dogjreaches the endof its rearward movement. This point will mark the end of. a half revolution of shaft 8. From this pointin the cycle the marker 62 with its plunger will begin to move upwardly away from the work and the operative feed dog 110 will begin its forward work feeding movement. At the end of the cycle-0r one revolution-of shafts 8 and 14 the plunger 50 will reach the limits.

of its upward movement and the feed dog 110 will reach the limit of its forward work-feeding stroke. Justrprior to the end of the revolution the cam. path 142 will begin to swing the arm 64 to 'move the inkling pad7 6 outwardly toengage the marker 62 as the plunger reaches the end of its upward-stroke so as to ink the marker} for the next marking operation. The parts have nowreturned to thepositions shown in Fig.1. If the selective revolution clutch control has been adjusted for a plurality of marking operations, other cycles similar to the one just described will follow until the desired number of'marking op- 2' erations have taken place. Just subsequent to the initiation of the last cycle or revolution of the shaft 8 (it being understood that shafts 14 and 8 rotate at the same speed) the bar 182 will release the latching lever 196 so that the bar 154 will be moved upwardly by the spring 168 to place its cam face in the path of the clutch pin head 26 to retract the clutch pin and stop the rotation of the driven shaft 14 at the end of the last revolutionQ 1 From the foregoing description it will be evident that a machine such as described, is of special utility for marking shoev up pers, and particularly for marking buttonhole and button locations upon the buttonhole fly and button quarter of shoe uppers.

edge of the stock and by reason of the feed adjustment, these location marks will be uniformly spaced from each other for each adjustment of the feed and their spacing may be uniformly varied, as desired.

Machines employing gangs of markers have been proposed for use in marking buttonhole and button locations, but in all machines of the gang type, the problem is very much complicated by the wide variance of pattern curvesand the necessity of providing mechanism, usuallycomplicated and rc qniring time in its adjustment, for position ing the markers for the varying pattern curves. Wit-ha machine such as l have described herein, curve variance need not be considered, as each of the successive location marks will be based upon a gage point having a determinate relation to the marking point, so that with the edge of the work against the gage point, there is no necessity of providing for curve variance.

Furt-hern'iore, the machine may mark both buttonhole and button locations simultaneously; or may mark the buttonhole locations in the buttonhole fly first; and then subsequently locations on the button quarter to which the finished fly has been subsequently stitched, thereby providing a machine which is practically universal and is adapted to variance in factory practice.

By having a selective revolution or work cycle mechanism coupled with an automatic feed, the machine becomes substantially more e'lticient by reason of the time saved from repeated treadlings and hand positioning of the work and is additionally advantageous as compared to the gang type of marking machine, in that there is no necessity of continued adjustment for curved variance. Except where limited by the prior art or by the specific terms of the appended claims, the invention as recited in the claims, is to be construed as of use generally for marking purposes. The nature of the marking instrumentalities may also be varied and the marking or location marking means as recited in the claims is intended to cover nun-king broadly and to include marking by cutting, indenting, perforating, cauterizing or color application. The specific structural embodiment disclosed, while preferable. is also susceptible of modification within the scope of the claims and the spirit of the invention.
