WARREN F. FRASER, OF DORCHESTER, MASSACHUSETTS, ASSIGN OR TO FRASER MACHINE AND MANUFACTURING 00., A CORPORATION OF MASSACHUSETTS. v

LAOING-HOOK-SETTING MACHINE.

To all whom it may concern:

Be it known that I, WARREN F. FRASER, a subject of the King of England, residing at Dorchester, in the county of Suflolk and State of Massachusetts, have invented new and useful Improvements in Lacing-Hook- Setting Machines, of which the following is a specification.

This invention relates to machines for setting lacing hooks in the uppers of boots and shoes, the object of the invention being to provide a machine which requires no skill upon the part of the operator other than to place the upper of the shoe in the machine, start the same and stop it, substantially in the manner hereinafter set forth. That is, the object of this invention is to provide a machine of the character set forth in which the upper is placed by the operator in correct position by the aid of suitable gages and after being placed in position the machine feeds the lacing hooks, punches the u per, sets the lacing hooks in the punched ho es in the upper, and spaces the lacing hooks at the desired distance apart in said upper.

It is further the object of this invention to provide convenient and practical means to vary or regulate the distance between the lacing hooks set in the upper.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings: Figure 1 is a left hand side elevation of my improved lacing hook setting machine. Fig. 2 is a right hand side elevation of the same, partly broken away. Fig. 3 is a plan view, partly in section, on line 3-3 of Fig. 1. Fig. 4 is a front elevation of my improved lacing hook setting machine, with the hopper removed and raceway broken. Fig. 5 is a front elevation, partly in section, on line 5 5, Fig. 1. Fig. 6 is a longitudinal section, partly in elevation, taken on line 66 of Fig. 3 Viewed from the left hand side 'of the machine and showing the parts in the res ective positions occupied thereby when the liook is being set in the upper, a portion of a shoe upper being shown in section therein and a portion of the machine being broken awayto save space. Fig. 7 is a view similar to Fig. 6 with the parts in the position occupied thereby when the stock has been fed forward ready to have a lacing hook inserted therein. Fig. 8 is a plan Patented April 28, 1908. Serial No. 344,137.

view, partly in section, on line 8-8 of Fig. 1, the same being partly broken away to save space, and illustrating a portion of the hook feeding mechanism. Fig. 9 is a plan view similar to Fig. 8 illustrating the hook feeding mechanism in a different position. Fig. 10 is a plan View, partly in section on line 10-1() of Fig. 1 of the mechanism for feeding the upper. Figs. 11, 12 and 13 are plan views similar to Fig. 10 showing the upper feeding mechanism in different positions. Fig. 14 is a detail front elevation of the rocker frame for feeding the upper. Fig. 15 is a detail side elevation as viewed from the left of Fig. 3 of one of the links forming a portion of the mechanism by means of which the upper is fed. Fig. 16 is a plan view in detail of the tilting frame upon which the hook feeding mechanism, the hook carrier, and the anvil are supported. Fig. 17 is a detail section, partly in elevation, taken-on line 1717 of Fig. 9. Fig. 18 is a detail section taken on line 1818 of Fig. 8. Fig. 19 is a detail side elevation of the lacing hook feed finger.

. Fig. 20 is a plan view of the resser foot, a

portion of the unch lever an a positioning gage for a rig t hand upper. Fig. 21 is a front elevation of said gage and Fig. 22 is a left hand side elevation of said gage. Fig. 23 is a plan view of the edge gage. Fig. 24 is a perspective view of the hook carrier plate.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 20 is the frame of the machine, said frame being provided with a bedplate 21, which is adapted to be fastened to the ordinary bench used in shoe manufactories. The shoe upper 22 is placed by the operator upon the work-rest 23 beneath the resser foot 24, when .a left-hand upper is to have lacing hooks inserted therein, as indicated in dotted lines (Fig. 3), with the front edge of said up er 22 bearing against the edge gage 25 and with the upper edge of said upper bearing against the top gage 26. The gages for positioning the shoe may be of any suitable construction.

The edge gage 25 is pivoted at 27 to the the work-rest 23, so that by loosening said screw 28 the edge gage may be rocked upon the pivot 27 until the bearing edge thereof is brought to the desired position, whereupon said edge gage is locked in position by tightening the screw 28. The top gage 26 is rendered adjustable longitudinally thereof by a screw 30 which projects through a slot 31 extending longitudinally of said top gage, said screw having screw-threaded engagement with the work-rest 23. A plate 32 fast to said work-rest bears against one side of the top gage to guide the same when the screw 30 is loosened and the gage is being moved toward or away from the punch. The work-rest plate 23 is rigidly fastened to a bracket 33 which is fast to the bed-plate 21.

The presser foot 24 is recessed at 34 to allow the punch 35 to feed the stock forward and beneath the anvil 36. The presser foot 24 is fastened to a vertical rod 37 adapted to slide in bearings formed upon a bracket 38 fast to the bed-plate 21. The rod 37 is forced downwardly to bring the presser foot 24 into contact with the work by a spring 39 the upper end' of which bears against the bracket 38 and the lower end against a collar 40 fast to the rod 37. Upon the lower end of the rod 37 is fastened a sleeve 41 which is adjustable longitudinally of said rod. The lower end of said sleeve bears against a lever 42 ivoted at 43 to the frame 20. The lever 42 has a cam-roll 44 journaled thereon and bearing against a cam 45 fast to the main driving shaft 46. A treadle rod 47 is attached to the lever 42, the lower end thereof being connected to a treadle (not shown in the drawing) which may be actuated by the operator so that the lever 42 may be rocked upon its pivot to move the rod 37 and presser foot 24 upwardly against the action of the spring 39, either by foot power or by means 0 the cam 45.

A hole is punched in the upper 22 by a punch 35 which is fastened to a lever 48 pivoted at 49 to a rocker frame 50. The lever 48 has a screw 51 in engagement with the left hand end thereof, said screw projecting downwardly therefrom and terminating in a spherical or ball-shaped en d which fits into a corresponding bearing in the upper end of a link 52. The lower end of the ink 52 is supported upon a stud 53 fast to a cam lever 54 pivoted to a stud 55 fast to bed-plate 21.

The vertical arm of the lever 54 has a camroll 56 journaled thereon which engages a cam-groove 57 formed in the cam disk 58, whereby a rocking motion is imparted to the lever 54 and through the link 52 a rocking .motion is imparted to the punch lever 48.

The punch 35 moves toward and away fromand. cooperates in its cuttin and feeding action with a die 59 which is fastened to the rocker frame 50. While I prefer to use a die 59 ofa separate piece of metalto cooperate with the punch 35, it will be noted that said die consists, merely, of a flat plate or disk with a shank thereon which fits into a corresponding hole in the rocker frame 50, but, if desired, said die might be formed in tegral with the rocker frame. For instance, the rocker frame might be constructed entirely of metal suitable for the die, in which case the die and the rocker frame would be in one piece, and in function it will be understood that said die and rocker frame are constructed in one piece, said die being rigidly fastened to the rocker frame and moving therewith.

The rocker frame 50 is pivoted to rock upon two pointed screws 60 and 6] having screwthreaded engagement with the frame 26 of the machine (see Figs. 6 and 7). A rocking motion is imparted to the rocker frame 56 by the cam disk 58 (Fig. 16) which has a camgroove 62 provided in its periphery in which is located a cam roll 63 journaled upon a lever 64 pivoted to a stud 65 fast to the bedlate 21. The lever 64 is connected by a ink 66 to a link 67 by a pin 68. The link 67 is pivoted upon screws 69, 69 fast to arms 76, 70 integral with an arm 71 which is counterbored to receive a hub 72 formed upon the rocker frame 50 (see Fig. 14). The arm 71 has ears 73 thereon which are clamped to the hub 72 by means of a clamp-screw 7 4. Said arm is still further fastened to the rockerframe 50 by a screw 74 which extends throu h the ears 73 formed upon the arm 71 and also through the rocker frame 50. it will be understood that the arms 7 t) and 71 are thus rigidly attached to the rocker frame 50 and form in function a part thereof, the rocker frame and arms 70 and 71 being formed in a separate piece simply for convenience in manufacture, but the resultant structure which will hereinafter be called the rocker frame in operation is exactly the same as though the frame 56 and arms 7 t) and 71 were integral one with the other. When the lever 64 is rocked by the cam-roll 63 in the groove 62 toward the right from the position indicated in Fig. 16 to that illustratr-al in Fig. 11, it will be seen that the rocker frame 50 will be rocked by means of the links will be broughtinto alinement with the axial line of the screws 69 which connect the link 67 to the arms 70 of the rocker frame 56, so that at the end of each feeding movement the axial line of the pivotal pin 75 will aline with the axial line of the screws 62).

It is essential in machines of this class that a ready means for varying the feed of the upper should be provided, so that the distance between adjacent lacing hooks upon different uppers may be increased or diminished, as desired, and for this purpose I provide a lever 76 pivoted to a stud 77 fast to the bed-plate of the machine. The lever 76 is connected by a pin 78 to a link 79, the opposite end of said link bein connected by a pin 80to ears 81, 81 integra with the link 67. The lever 76 is locked in position by pins v82, 82 which project into holes 83, 83 provided in the plate 84 fast to the bed-plate 21. The pins 82, 82 are located u on opposite sides, respectively of the ham. le arm 85 and thus lock the same in position. Said pins are easily removed from the holes 83, 83 and are placed by the o erator in the pro er holes to lock the handle 85 in position. desired, an index may be placed upon the plate 84 or upon the bed-plate adjacent thereto, so that the operator can set the handle 85 in position for any desired distance between the lacing hooks. When the handle 85 is rocked from the position indicated in Fig. 10 'to that illustrated in Fig.- 12 the link 79 is drawn toward the right in said figures, thus rocking the links 66 and 67 upon their pivots and rocking the rocker frame 50 upon its pivot to move the punch toward the left in said figures, and when the feed of the upper takes place as hereinafter described, the axial line of the punch will be brought into alinement with the axial line of the anvil at the end of the feed and the axial line of the pin 75 will be substantially in alinement with the axial line of the screws 69, as illustrated in Fig. 13.

The lacing hooks which are to be set in the uppers of boots and shoes are placed in quantity in a hopper 86 which consists, mainly, of

a casing 87 supported upon a bracket 88 fast to the frame 20 and having journaled therein a rotary picker plate (not shown in the drawings) to which a rotary motion is imparted by means of a bevel gear 89 fast to a shaft 90 journaled in said casing. The bevel gear 89 meshes into a pinion.91 fast to a shaft 92 journaled in. bearings upon said casing and driven by a pulley 93 fast thereto and connected by a belt 94 to a pulley 95 formed upon the hub of the main driving pulley 96 (Fig. 5). The main driving pulley 96 is loosely mounted upon the main driving shaft 46 and is connected thereto, in order to rotate said shaft, by a clutch 97 which is operated frame 104 (see Figs. 3, 5, 6, 7 and 16).

100 leads from the hopper 86 downwardly at an incline, the lower end of said raceway being rigidly fastened to the bracket 38. The lacing hooks 101, 101 slide down said raceway till the lowermost lacing hook rests against a detent or stop spring 102 fast to the lower end. of said raceway, as illustrated in Fig. 8. Said lowermost lacing hook at this time rests upon the horizontal bend. 103, as illustrated in Fig. 17. The lacing hook is next fed from saidraceway and carried to a lacing hook carrier by which it-is forced through the shoe upper and. against the anvil, all by mechanism which I will now proceed to describe.

The mechanism for feeding the lacing hooks from the raceway to the carrier and setting the same is supported upon a tilting The tilting frame 104 is pivoted to rock about a horizontal axis upon the pointed ends of screws 105, 105. fast to the frame 20. A rocking or tilting motion is given to said frame by a cam 106 having a roll 1.07 in the path thereof which is journaled to rotate upon a pin fast to an arm 108 integral with and projecting downwardly from the tilting frame 104. Upon the top of the tilting frame 104, at its forward end, are fastened three plates 109, 110, and 111 which constitute guide plates for the lacing hook as it is being fed from the lower horizontal portion of the raceway to the lacing hook carrier 112. The plates 109 and 111 form at their adjacent ends a continuation of the lower horizontal portion of the raceway when the tilting frame is in its lowermost position, or in the position shown in Fig. 8.

Between the adjacent edges of the plates 109 and 110 is a passageway 113 which terminates at its forward end adjacent to the hook carrier plate 114. The hook carrier plate 114 forms the top of a hollow cylinder 114 and said top is cut out to form a recess 114 this recess also extending downwardly from the top along the rear wall of the hollow cylinder 114 which is cut through into the interior of said hollow cylinder and thus forms I the recess 114 which is adapted to receive the head of the lacing hook, while the shank projects upwardly from the top 114. The lacinghook carrier 112 has a cylindrical stem upon its upper end which projects into the hollow cylinder 114. Said plates 109, 111 and 110 constitute, therefore, an auxiliary raceway for guiding the lacing hook from the lower horizontal portion of the raceway to the lacing hook carrier 112, it being understood that the adjacent edges of the plates 109 and 111 form one portion of said auxiliary raceway and the adjacent edges of the plates 109 and 110 the other portion of said auxiliary raceway, so that said auxiliary raceway guides the lacing hook along a substantially right angled pathway, leading first from the horizontal portion of the raceway 100 to the passageway 113 and second along the passageway 113 to the lacing hook carrier. The lowermost hook upon the raceway is carried from the lower portion of the race way along between the plates 111 and 109 to the center of the passageway 113 or to the position illustrated. in Fig. 9 from the position illustrated in Fig. 8 by a hook feeding lever 115 which is pivoted upon a stud 116 fast to a cap-plate 117 which, in turn, is fastened to and forms in function a part of the tilting frame 104.

A flat spring 118 is fastened to the lever 115 and projects rearwardly beyond said lever, contacting with a roll 119 when the parts are in the position illustrated in Fig. 9. The roll 119 is journaled upon a stud 120 fast to a slide 121 constructed to slide in ways 122 formed in the top of the tilting frame 104. The stud. 116 is encircled. by a torsional spring 123 (Fig. 7), one end of said spring being fastened to the cap-plate 117, the other end thereof being fastened to the lever 115, the action of said torsional spring being to hold the lever 115 or the flat spring 118 fast thereto in contact with the friction roll 119.

In the forward end of the lever 115 is located a hook feeding finger 124 pivoted to a pin 125 fast to the lever 115. A spring 126, which is supported upon the lever 115, bears downwardly upon the forward end of the hook feeding finger 124, so that if said finger should strike upon the top of a lacing hook instead of between two adjacent lacing hooks, it would yield slightly and thus avoid damaging said lacing hook. The lever 115 is rocked upon its pivot 116 from the position illustrated in Fig. 8 to that illustrated in Fig. 9, thus feeding the lowermost hook from the horizontal portion of the raceway into alinement with the passageway 113, by the roll 119 and stud 120, which, as hereinbefore set forth, are fast to a slide 121. A reciprocatory motion is imparted to said slide at the right time in the operation of the machine by a cam 127 (Figs. 6 and 7) fast to the main driving shaft 46, operatively connected by a cam roll and stud to a lever 128 pivoted to a stud 129 fast to the frame of the machine.

The lever 128 is connected by a link 130 to a collar 131 clamped to a rod 132 and adapted to slide longitudinally thereof in the tilting frame 104. An ear 133 projects upwardly from the collar 131 and through this ear projects a pin 134 which is fastened to the slide 121. A spiral spring 135 encircles the pin 134, one end of said spring bearing against the slide 121 and the other against the ear 133. The rocking lever 128, by its cam 127, will impart a reciprocatory motion to the rod 132 and also to the slide 121, and if the slide 121 or any of the parts supported thereon should encounter an obstruction such as a misplaced lacing hook, the spring 135 will yield and thus prevent a smash up of the machine or damage to said lacing hook. As the slide 121 is moved backwardly from the position illustrated in Fig. 8 to that illustrated in Fig. 9 the hook feeding finger 124, which, when the parts are in the position illustrated in Fig. 8, projects downwardly between the lowermost lacing hook upon the raceway and the lacing hook ad jacent thereto, will be moved from the position illustrated in Fig. 8 to that illustrated in Fig. 9, carrying said lowermost lacing hook away from the detent 102 and along between the plates 109 and 111 to the center of the passageway 113, as illustrated in Fig. 9. This motion is imparted to the lacing hook feed finger 124 by the reci n'oeating movement of the slide 121 toward the left. The roll 119 moving along in contact with a cam face 136 upon said lever 115 will rock the same to the position illustrated in Fig. 9. During the latter part of this rocking movement of the lever 115, if the lacing hook should encounter an obstruction or if there should be a slight difference in width between one lacing hook and another, the llat spring 118 will yield so that no jamming of the lacing hook will take place.

' It is evident that if the lacing hook were to be fed, as hereinbefore described, along the plate 111 and into alinement with the passageway 113, if nothing were interposed in said passageway at the right or in front of the lacing hook (Figs. 8 and 9) the same would be liable to fall off of the plate 111 and thus the lacing hook would be dropped out of the machine and could not be fed to the upper to be set. To prevent any such accident a hook holding linger 137 is provided (see Figs. 6 and 7) and when the lacing hook is fed along the plate 1]], as hereinbefore described, to the passageway 113, said hook holding finger will be in the position illustrated in Fig. 7 and will form a continuation in effect of the plate 109, so that the lacing hook will be fed onto said hook holding finger. The upper portion of the finger 137 is hook-shaped and adapted to enter the space between the head and shank of the hook. Said hook holding linger is pivoted at 138 to the tilting frame 104 and is normally held in the position illustrated in Fig. 7 by a torsional spiral spring 139, one end of which is fastened to said linger the other to the tilting frame.

The lower edge of the hook holding linger 137 is flattened and projects toward the left of the pivot of said 'finger at 140, this projection resting against the bottom of the grmweor space in the tilting frame 104- in which the slide 121 is adapted to move. When the slide 121 is moved forward or toward the right, from the position illustrated in Fig. 7 to that illustrated inFig. 6, the hook which at that time rests upon the finger 137 is pushed along the passageway 113 by a finger 141 which is rigidly fastened to said slide 121. As said finger advances the hook holdin finger is pushed backwardly and downwardTy from the position I illustrated in Fig. 7 to that illustrated in Fig. 6 by a friction roll 142 journaled to rotate upon a pin 143 fast tothe slide 121, so thatas soon as said hook enters the passageway between the plates 109 and 110 and becomes guided thereby, the hook holding finger is drawn out of the hook and substantially into the position illustrated in Fig. 6. A further forward motion of the slide 121 pushes the hook along the plates 109 and 110 and onto the hook carrier plate 114.

An arm 144 is pivoted by a pin 145 to the tilting frame 104. Said arm is connected by a pin 146 to a link 147, the other end of said link being connected by a pin 148 to the frame 20. The anvil 36 is formed upon or fastened to 'the lower end of a screw 150 which projects through the front end of the arm 144 and is adjusted longitudinally thereof in said arm by means of a nut 151 located in a slot 152 provided in said arm. The screw 150 and anvil 36 are secured in position after having been properly adjusted by a set nut 153.

The lacing hook carrier 112 is pivoted upon the tilting frame 104 to a pin 154, said pin passing through ears 155, 155 upon the tilting frame 104, said ears being located above and below said lacing hook carrier.

It will be seen that the hook carrier 112 constitutes, in effect, arocker arm pivotally supported upon the movable or tilting frame 104, with the hook carrier plate 114 fast to the outer end thereof, so that when said hook carrier 112 is rocked upon its pivot the same moves bodily away from the lacing hook after the same has been set in the upper and thus the hook carrier plate is disengaged from the head of the lacing hook.

The position'of the lacing hook carriercan be regulated and moved toward or away from the end of the passageway 113 by a set-screw 156 having screw-threaded engage-' ment with said lacing hook carrier and with its inner end bearing against an ear 157 7 formed upon the tilting frame 104. The

screw 156 is held normally in contact with the tilting frame by a flat spring 158, one end of which is fastened to said tilting frame, the forward end thereof bearing against an arm 159 formed on the lacing hook carrier 112.

When theoperator desires to set lacing hooks in a right hand upper, said upper is positioned by means of a gage 160 (Figs. 20 to 22 inclusive). This gage is provided with a slot 161 and is adjustably fastened to the presser foot 24 by means of a screw 162 which extends through said slot and has screw-threaded engagement with said presser foot. An ear 163 upon the plate 160 extends downwardly therefrom in front of the presser foot 24 and has an index 164 thereon. Another ear 165 extends upwardly from the rear edge of said ga e 160 and has a series of index marks 166 t ereon. The mark 164 shows the operator where to place the upper edge of a right upper in starting a machine when the first lacing hook is to be inserted. One of the index marks 166 is placed in alinement with an index mark 167 upon the punch lever 48 and the gage is then fastened to the presser foot 24 by means of the screw 162. The distance from the point where the first or upper lacing hook is placed in the shoe varies with different styles of shoes and with different manufacturers. Therefore, a series of marks 166 is provided, any one of which may be placed in alinement with the index mark 167 upon: the lever 48 to suit varying requirements found in different shops and existing under different conditions.

It is evident that if it is desired that the punch shall make a hole in the upper nearer the to edge, one of the marks 166 at the right ig. 20) will be placed in alinement w1th the index mark 167. On the contrary, if a longer distance from the upper lacing hook to the to edge of the upper is required, one of the in ex marks 166 at the left (Fig. 20) will be placed in alinement with the index mark 167, so that having the gage 1.60 correctly located the operator places the top of the right hand up or in alinement with the index mark 164 an(v then locates the upper in the proper position for the punch to perforate the same at the required distance from the top of said upper.

The operation of the mechanism hereinbefore described is as follows: The operator first depresses the presser foot treadle, raising the presser foot 24, and inserts the u per, whether it be a right hand or a left han u per, beneath said presser foot upon the wor plate in the proper location for the punch to punch a hole therein in the correct position,

eing guided as to the placing of the same, so far as the front edge of the upper is concerned, by the edge gage 25, whether the upper be a right or left hand upper and being assisted in placing the upper in the correct position relatively to the distance from the top edge of the upper by the to gage 26, in the case of a left hand upper, an by the gage 160, in the case of a rlght hand upper, the particular manner of placing said uppers by the aid of said gages having been hereinbefore described. After having placed the u per in osition the operator releases t e presser oot, allowing the same to descend and clamp the upper to the work-plate. At this time the punch is raised and in its extreme position toward the left as viewed from the front of the machine. The operator now throws in the clutch and the main driving shaft is rotated by the clutch pulley 96. The punch lever 48 is rocked by means of the link 52, cam lever 54 and cam groove 57, depressing the punch until it perforates the upper against the die plate 59. The presser foot is then raised to release the upper so that it may be fed, by the cam 45. The rocker frame then moves, together with the punch, toward the right, said rocker frame being rocked upon its pivots by means of the cam groove 62 cam lever 64, and links 66until the median axial line of the punch is brought into alinement with a vertical plane extending through the center of the passageway 113 and through the center of the anvil 36. The presser foot now descends and clamps the upper to the work-plate. The punch is then moved upwardly and retreats toward the left, as viewed from the front of the machine, being moved by the rocker frame on which it is sup orted.

When the operator pl aees the shoe upper in the machine, as hereinbefore described, the hook feeding fin er 124 and the lever 115 are in the position illustrated in Fig. 8,- i. (3., the tilting frame 104 is in its lowermost position and the auxiliary raceway is in alinement with the lower horizontal portion of the stationary raceway in readiness to have a hook fed from said stationary raceway onto said auxiliary raceway. The hook feeding finger 124 is located back of the lowermost hook on the raceway. Now, as the shaft rotates said, hook feeding finger is rocked from the position shown in Fig. 8 to that shown in Fig. 9, being rocked from one position to the other by the movement of the roll 119 toward the left (Figs. 8 and 9). The slide 121 is at this time retreating or moving toward the back of the machine.

The hook feeding finger moves the hook from the lower portion of the raceway onto the tilting frame 104 between the plates 109 and 111 and by the time that said hook feeding finger has moved the hook into the passageway 113,the forward end of the slide 121 has retreated to allow the lacing hook to be pushed into said assage and. also to allow the hook holding inger 137 to assume a substantially vertical position, as illustrated in Fig. 7, and to receive u on its hooked end said lacing hook. The 100k feeding finger 124 finishes the feeding of the hook into the passageway 113 at about the same time that the punch finishes feeding the material forward in order to have a new lacing hook set therein. As the punch begins to rise and to retreat or move toward the left (Fig. 4) the slide 121 moves forward and the roll 142 strikes tl1e-hook holding finger 137, moving it from the position illustrated in Fig. 7 to that illustrated in Fig. 6 and pushing the hook forward along the passageway 113 and onto the hook carrier plate 114. The anvil 36, during the motions hereinbefore described,

has been in its raised position and the tilting frame in its depressed position, as illustrated in Fig. 7. During the latter part of the forward motion of the slide 121, however, the tilting frame is rocked upon its pivot by the cam 106 which rocks the arm 10S integral with the tilting frame 104, so that the tilting frame, with the hook carrier 112 and hook carrier plate 114 thereon, is raised to meet the descending anvil 36, which is fast to the arm 144, said arm being rocked downwardly when the tilting frame 104- is moved upwardly by reason of the rear end of the arm being connected to said tilting frame, while the arm itself is pivoted upon the link 1-17 fast to the stationary frame, so that an up ward movement of the tilting frame will rock the arm 144 so as to move the front end thereof downwardly with the anvil attached thereto.

The hook carrier plate 114 moving upwardly with the tilting frame forces the shank of the lacing hook through the perforation made in the upper of the boot or shoe by the punch, as hereinbefore described, and clenehes the shank of said hook upon the anvil 36. Just as the anvil is moving upwardly a slight extent or enough to release the pressure upon the upper, the rod 132 abuts against the hook carrier 112 and rocks the same upon its pivot so as to withdraw the hook carrier plate from the lacing hook, it being noted that the-axis of rotation of said carrier extends parallel to the longitudinal median line of the shank of a lacing hook thereon, whereby when said carrier is rocked it may be disengaged from said lacing hook. During this forward motion of the rod 132 the spring 135 will yield and the slide 121 will remain stationary, said slide being stopped by theroll 1 19 abutting against the lever 115, as illustrated in Fig. 8.

It is evident that the slide 121 and the rod 132 will move as one piece unless an obstruction is encountered by the slide 121, such as hereinbefore set forth, whereupon the spring 135 will yield, the slide 121 will remain stationary, and the rod 132 will move forward to perform its function in actuating the lacing hook carrier to remove the same from the lacing hook which has been set, so that under normal conditions the slide 121 and sliding rod 132 move as one piece and constitute, as a whole, a slide.

As soon as the lacing hook carrier has been withdrawn from the lacing hook, the tilting frame, together with said lacing hook carrier and its holder, descends, the slide 121 begins its retreating motion and the lacing hook holder assumes its normal position ad jacent to the end of the passageway 113 in readiness to receive a new lacing. hook.

It will be noted that during the preceding movements of the different parts the presser foot 24 is raised to free the upper so thatit
