COMBINED LIFT-CUTTING, ASSEMBLING, AND HEEL-BUILDING MACHINE.

Specification of Letters Patent.

' Application filed August 17, 1912. Serial No. 715,536.

This invention relates to the art of heel building, and has for its object to provide a novel combined lift cutting, assembling, and

heel building machine.

Heretofore, so far as I am aware the cut-' ting of the lifts, either whole or pieced, has been in practice conducted as a distinct operation, the cut lifts being supplied to an operator in certain sizes and thicknesses, ac-

cording to the character of heel he may be intructed to build, a large number of each size I of lift entering into the construction ofthe heel being placed in separate compartments within his reach. These lifts are selected one at a time bythe operator and piled one upon the other, after having paste applied thereto, the lifts being compiled on a machine which subsequently is actuated to shape, compress, and nail them together. This practice, which, so far asI am aware, is universal in the shoe industry, necessarily requires the manufacturer to carry an enormous number of lifts in stock, so that, according to the character of heel to be built, the required number of lifts of the requisite size and thickness may be supplied to the operators. k

it is the object of my invention to perform all of the operations entering into the building of a heel with the use of a single machine, which is practically automatic in operation. That is to say, I aim to provide a machine which will enable a single operator to cut the various sizes and I thicknesses of lifts entering into the heel the art.

dies slidably mounted therein, with means for depressing said dies at stated intervals, and means for causing the head to be automatically rotated at will for a given distance; an automatic paste-applying device; a rotatable mold-carrying table in which the cut and pasted lifts are deposited from the dies; and a nailing device carried by one of said dies with means j for driving a nail therefrom through the lifts in the I mold. The number of dies mounted in the rotatable head may be sufficient in number and vary in size so as to include all sizes of lifts which. will ordinarily be made for given classes of shoes. In addition, the dies are made removable so that other sizes or shapes of dies may be inserted in the head, the openings for the dies being large enough toreceive a series of the largest size dies thatwill ever be used, so that, if desired, the larger dies can be removed and smaller dies inserted by using appropriate bushings, as will be well understood by those skilled in the largest heel, and their interior dimen sions will be decreased by an insertion of suitable blanks, according to the shape and size of the heel being formed. These mat-- ters are all within the range of mechanical skill, and need notbe described more fully.

Referring now to the drawings, 1 indicates the base of the machine on which is mounted a circular standard 2 having rotatably mounted thereon, near the upper end thereof, a circular head 3. The column 2 has an integral portion 4, projecting beyond the head 3, this upwardly extending portion being bifurcated to provide a bearing space for a lever-arm 5, which is pivoted therein by means of a bolt 6 passing through apertures in the bifurcated portion. The bolt 6 is extended a considerable distance to one side of the part 1, as indicated at 7, and near its outer end is provided with an aperture in which works a plunger 8, operated in a manner hereinafter described. The head 3 is provided around its circumference, and at points removed from its periphery, with equi-distant, vertically-disposed recesses 9, in which are removably seated a series of cutting dies 10, one of which is shown in detail in Fig. 11. These cutting dies, with the exception of the last one of a series, to be later described, are all of the same construction, varying only in size, and are of the shape of a lift to be cut, being provided at their lower end with a beveled cutting edge 12. The dies are made hollow and within each of the dies is mounted a plunger 13, which is provided on one face with a pointer 14 working through an opening 15 in the corresponding face of the die, and moving over a graduated scale 16 on such face of the die, adjacent to the side of the opening, so that as the lifts are cut the plunger 13 will be raised thereby and the pointer indicate on the scale 16 the thick ness of the lift. For convenience I provide a second opening 17 on one or both-sidesof the die, and the part of the plunger operating in front of this opening is provided with a scale 18 so that the operator, by looking at this part of the die, can ascertain the thickness of the lift out by comparing the scale with the upper edge of the opening 17. For a similar purpose ascale may be applied on the flat face of the plunger 13 corresponding to that part appearing through the opening 15, but at the top of the plunger, as indicated at 20, so that the distance the respective marks of the scale will appear above the upper edge of the die will indicate the thickness of the lift. Either one or all of the scales described may be employed.

As stated, all of the dies, except the last one of a series, have the construction shown in Fig. 11. When the last lift is cut, pasted and applied, however, it is necessary to nail the compiled lifts together, and with this object in view the last die of a series, is provided with a nailing device, this construction being shown in Fig. 3, and on an enlarged scale in Fig. 6. In this construction the die 10 is provided with a plunger formed in two parts 21, 22, the upper part 21 being formed with a recess 23, in which is housed a coil spring 24, the two parts of the plunger being secured after the insertion of the spring by one or more screws 25. An aperture 26 extends vertically and centrally through the plunger as a whole, and in this aperture is mounted a nail driver 27, which is normally held in an upward position by the spring 24: bearing against a collar 28 secured on the nail driver; Adjacent to the aperture 26 there is provided a second aperture 29 extending from the top of the plunger to near the lower end thereof, where it communicates with the aperture 26, the opening in the wall of the plunger between the apertures 26 and 29 being large enough to permit a nail 30 inserted in the aperture 29 to fall into the aperture 26 below the lower end of the nail driver 27. At the lower end of the aperture 29 a leaf-spring 31 is secured, the free end of which extends across the aperture 26 to thereby prevent the nail 30 from falling out of such aperture, but yielding to permit the discharge of the nail on the descent of the nail driver 27. Each die 10 is provided at its lower end with aslot 32, in which works the end of a pin 33 secured in the lower end of the plunger 22, which thereby prevents the plunger from falling out of the die, and allows limited upper movement thereof. On opposite sides of each recess 9 in the head 3 two smaller recesses are provided, in each of which is houseda coil spring 3st which bears against a lug 35 secured on the die 10 near the top thereof. Screws 36 mounted in the top of the head 3 have eccentric heads adapted to be turned over the lugs 35'to limit the upward movement of the die.

The dies andthe nail driver operate as follows: Mounted in the outer free end of the lever-arm 5 isa screw bolt 37 having a hand wheel 38 and a lock nut'39 to enable the bolt to be adjusted in the proper position in the lever-arm and locked in such position. On the lower end of this screw bolt is mount ed a hollow hammer 40 which is adapted to engage the top of each die and press the same downward as the outerend of the leverarm 5 is depressed. The hammer is made hollow to permit the rise of the plunger in the die. This movement of the lever-arm is effected through the medium of a rod il pivotally secured to the opposite end of the lever-arm to that carrying the hammer, the lower end of said rod being provided with a ring 42 in which wor {s an eccentric 43, these parts being shown in dotted lines in Fig. 17. The eccentric 4-3 is fixedly secured on a cross shaft 44 on which is mounted a loose pulley 45 and a fast pulley 46. A. beltshifter 47, slidably mounted on a short bearing rod -18, embraces the driving belt a9, and by manipulating this belt-shifter through the medium of a lever 50, bell-crank lever and link 50*, the belt is shifted from the loose to the fast pulley in the usual manner, to operate the machine. The lever 50 is controlled by a spring 51, and the operator presses said lever to transfer the belt to the fast pulley to enable the machine to make one cycle of movement, and on releasing the lever the spring presses it upward, thereby automatically transferring the belt to the loose pulley to permit movement of the maohine to cease. The friction between the movable parts of the machine is such as to cause it to stop after the driving power has been removed, theoperator soon learning how long to keep the driving belt on the fast pulley. This form of drive control is preferred by many manufacturers for their machines, butI wish it to be understood that I do not limit my invention to the particular form of driving mechanism shown, as obviously a well known clutch drive could be employed, with means for positively stopping the machine after one cycle of movement, such device being well known in the art and needing no illustration. Then the eccentric 4:3 is actuated the rod 4:1 will be alternately raised and lowered, the upward movement of the rod causing the free end of the lever-arm 5 to descend and depress the die 10 which may be under the hammer 40. The lever-arm 5, near its point of pivotal connection with the rod 41, is provided with an outwardly-extending arm 52, on the outer end of which is pivotally mounted the upper end of a link 53. The lower end of the link is pivotally secured to a throw-lever 5-1} which is pivotally mounted at in the end ofa bracket 56 secured by bolts 57 to the upper part l of the column 2. The inner end of the throw lever 5a is bifurcated, and embraces a bearing block 58 provided on the plunger 8. (see Fig. 3) to which it is pivotally mounted by means of a pivot pin 59.

From the above construction it will be seen that as the inner end of the lever-arm 5 is thrown upward by the rod 4:1 the outer end of the throw-lever .54 will be depressed thereby moving the plunger 8 downward into the aperture 26 where it engages the top of the nail-driver 27 and depresses it to drive the nail, which had previously been tion of molds 63. Four of such recesses and molds are shown in the drawing (see Fig. 2), such molds being arranged directly opposite each other, or at equal distances apart, so that when one mold is under the nail driving die (Fig. 3) the neXt mold will lie adjacent to the heel-blank receiving board,

presently described, and this position of the respective molds occurs in each quarter revolution of the mold-carrying table 62. Depending from the bottom of the table 62 under each of the recesses containing a mold is a bracket 64i- (Figs. 3 and 8), in which is mounted a plunger 65 which is normally pressed upward by a coil spring 66 located between the bottom of the bracket 64 and a collar 67 secured on the plunger. This spring tends normally to press the plunger 65 upward, but such action is restrained by a shouldered pawl 68, yielding downwardly only, and controlled by a spring 69, the said pawl being mounted on a depending portion of the head opposite the bracket 6%, as shown more clearly in Fig. 3. Removably mounted on the top of the plunger is a plungerhead 70, which, in its depressed position, shown in Fig. 8, forms the bottom of the mold 63. Initially said plunger-head 7O occupies a position at the top of the mold, as shown at the left of Fig. 3, and also in Fig. 15. It is made removable, so that a larger or smaller plunger-head may be substituted, according to the size of mold being used. The plunger 65 is provided on one side with a series of ratchet teeth 71, which are engaged by the pawl 68 so that the plunger can descend against the resistance of the spring 66 as the lifts are pressed into the mold 63, the pawl, as stated, preventing the plunger from moving upward during the operation of filling the mold. The pawl 68 is mounted on a plate 7 2 which is pivotally mounted by means of a bolt 73 on the under side of the table 62. At certain intervals, as later referred to. the plate 72 will be turned on its pivot 73 to release the pawl from engagement with the teeth 71 and allow the plunger 65 to rise. A set screw 7st, having a friction disk 75 on its ends, is turned to cause the friction disk to engage the plunger 65 more Or less firmly so that the plunger 65 will'be caused to rise gradually. It

is stopped, with its upper side flush with the surface of the moldcarrying table, by means of a lug 7 5 on the bracket 64 engaging the collar 67.

In order to rotate the head 3 I provide the following mechanism: Extending upward through the column 2, and rotatably mounted therein, is a rod 76 having secured thereon near its upper end an arm 77 (Fig. 6) extending through and working in an elongated aperture 78, and having pivotally mounted on its outer end a shouldered ratchet 79 yielding in one direction only under the influence of a weight 80. On the under side of the head 3 there is provided a circular series of ratchet teeth 81 with which the pawl 79 engages. The rod 76, at its lower end (see Fig. 4) is provided with a crank-arm 82, which latter is provided at its outer end with a slot 83 in which engages a pin 8-1 passing vertically through a lever 85. Extending outward from the column 2 is a bifurcated bracket 86 (see Figs. 1 and 4:) which provides a recess for supporting the lever 85. At its inner end the lever has pivotally mounted thereon at 87 an endpiece 88 provided at its end with a hook 89, the pivotal connection 87 being a shouldered one so that the end-piece cannot descend below the horizontal, but is free to move upwardly. It is held normally in the horizontal position by means of a spring 90, (indi cated by dotted lines) secured at one end to the end-piece, and at its other to the base 1. The parts just described are shown only in plan in Fig. 4:, but the arrangement will be made clear by an inspection of the bottom of Fig. 1, where identically the same construction of lever is mounted on the opposite side of the base. This lever is indicated by 91, and is pivotally connected at 92 to an arm 93 secured on a rod 9 1 rotatably mounted at its lower end in a bearing 95 on the base, and at its upper end extending through the standard 61 of the mold-carrying table and being journaled in the top thereof, as shown in Fig. 3. Pivotally connected to the outer end of the lever 91, as indicated at 96, is an endpiece 97 having a hook 98, the said end-piece 97 having a shouldered connection at 96 so that it may not descend below the horizon tal but be free to move upwardly. It is normally held to the horizontal by means of a spring 99 secured at one end to the end-piece and at its other to the base.

The numeral 100 indicates a throw-lever which is pivotally mounted by a slotted connection at its lower end on the base, as indicated at 101, and at its upper end is provided with a knee-piece 102 which has a tongue 103 slidably mounted in a groove provided in an arm 10% extending at right angles to a bracket 105 mounted on the frame of the machine. The inner end of the lever 91 is provided with a slot 106 in the lever 91 to be thrown inward on the pin as a pivot, so that as the disk 109 turns it will engage the hook 98 and draw the lever 91 inward, this operation continuing until the hook 98 has been carried tothe opposite side of the disk, when the pin 108 s will move out of engagement with the hook. The lever 91 is then automatically retracted to the position shown in Fig. 1 by means of a spring 110 secured at one end to the lever and at the other to the pin 107, or to some other part of the throw-lever 100. After the throw-lever 100 is released it is automatically turned to normal position by means of a spring 111 secured at one end to the lever 91, and at its other to a post 112 projecting upwardly from the base 1. The inward movement of the lever 91, as above described, will cause a partial rotation of the shaft 94 through the action of the arm 93. Mounted on the shaft 9st near the upper end thereof is a collar 113 from which projects an arm through an opening 114 in the side of the standard 61, said arm having mounted on its outer end a ratchet similar to the ratchet 79 above'described, said ratchet engaging a circular series of teeth 116 provided on the under side of the mold-carrying table 62. As the shaft 94 is rotated the pawl 115 engages with a tooth 116 and causes a quarter rotation of the mold-carrying table 62.

The lever 85 corresponds to and operates in the same manner as the lever 91, its throw-lever, however, being shown only in section in Fig. 4 and being indicated by the numeral 117, the numeral 118 indicating the pin connecting it with the lever 85. This lever is operated by a pin 119 secured near the periphery of a disk 120, which, in turn, is secured on the shaft 4:4; knee-piece of the throw-lever 117 is shown in Fig. 2, and is indicated by the numeral 121. By moving this outward in the same manner as described with reference to the lever 100, the end-piece 88 will be thrown inward so that the pin 119 can engage with he hook 89 and draw said lever 85 inward. In this operation the rod 76 will be given a quarter revolution through the medium of the arm 82. thereby, through the arm 77 secured on the rod 76, causing the ratchet 79 to engage one of the circular series of teeth 81 and rotate the head 3 a given distance. The lever 85 is returned to normal position by a spring 122 in the same 'manneras the A portion of the lever 91, and as these levers are so. drawn backward their respective shafts 76 and 9 1 will be turned in the reverse direction to that previously describerhand the ratchets 79-and 115 will ride over the teeth on the under side of the head and mold-carrying table, respectively. After the throw-lever 114- has been pressed outward it is drawn backward to normal position, when released, by means of a spring 123, secured at one end to a post 121 and at its other end to the lever 85. '1l1eim1neral 125 indicates the cutting block. which supports the leather while the lift is being out by a die 10. This block is supported on a bracket arm 1% projecting outward from the column 2, and is rotatably mounted thereon; N ear its base the cutting lock is surrounded by a series of ratchet teeth 12'? with which engages a gravity pawl 12S mounted on the end of a rod 129.. The

, other end of this rod is pivotally connected of this being to present a different surface beneath the dies, so as to increase the life of the cutting block by preventing the same part of the surface thereof being always under the cutting dies. After the heel lifts have been assembled in the mold 63 and nailed together the nextstep is to cause the heel blank to be discharged from the mold.

This is accomplished by providing a lug 134. on the frame member 132, before referred to, in the path of the arm 72 carrying the pawl 63, so that as said table is rotated the projecting end of the arm 72 will strike the lug 13%, thereby throwing the pawl 68 out a table 136, which is slidably mounted on ways 137 provided on the upper side of an auxiliary frame 138, shown more clearly in Fig. 1.

The automatic discharge of the heelblanks on to the board 135 is effected by the following mechanism: Slidably mounted in bearings in the lower part of the frame 138 is a bar 139 (see Figs. 1,2, 8 and 14) which is normally pressed outward or toward the board 135 by means of a spring 1 10. Secured to the bar 139, near the outer end thereof, is an inwardly curved arm 1 11 having a transverse groove 142 provided in its upper surface near its point of connection withthe bar 139. Depending from the under side of the mold-carrying table are four striker arms 1&3 arranged at equal distances apart,which, as the mold-carrying table revolves, are adapted to successively engage the curved arm 141 and thereby force the bar 139 inward against the resistance of the spring 140. This continues until the particular striker arm engaging the curved arm 1 11 reaches the groove l l2,when the engagement of these two parts is released and the spring 140 throws thebar 139 outward. Secured on the bar 139 is a vertically-disposed rod 14 1 which extends to a point slightly above the upper surface of the mold-carrying table 62 where it is bent at right angles to itself to extend over said table parallel with the surface thereof, as indicated at 145, and is provided at its outer end with a push plate 146. j The push plate 1&6 is located, when the spring 140 is in its retracted position, directly behind the mold lying in front of the board 135, and the location of thelug 134 is such that the heel blank, indicated by the numeral 1&7, will be discharged from the mold as the latter reaches the position referred to, such position of the parts being shownin big. 7. As the arm 1 11 is released in the manner above described, the push plate 1&6 carried by the rod 145 will be thrown outward, thereby discharging the heel on to the board 135. This operation is repeated in each cycle of movement of the machine. The board 135, as shown more clearly in Fig. 2, is divided into compartments by means of vertical parallel partitions 143, and each compartment is designed to receive a certain number of heels. As one compartment is filledthe board is moved to bring the adjacent compartment opposite the mold, and this movement is effected as follows: Pivoted in an upright portion 1&9 of the auxiliary frame 138, as indicated at 150, is a handlever 151 on the inner end of which is pivotally mounted a gravity pawl 152 (see Figs. 1, 3 and 1a), which is adapted to engage the teeth of a ratchet bar 153 secured on the under side of the table 136. By manipulating the hand-lever 151 the operator can readily slide the table 136 on its ways to bring the appropriate compartment in line with the mold from which the heel After all ofthe comhas been discharged. partments on the board have been filled the same can be removed and carried to the heelpress and a new board be inserted on the table 136.

1 After the lift is cut and before it is deposited in the mold, it isnecessary to apply automatically in the following manner: Mounted on the column 2 and projecting a suitable distance outward from the same is a paste-pot 15-1 pivotally mounted in which, at 155, is a bellcrank lever 156 carrying at one end a paste-applier 157, which may be in the form of a brush, dauber, or other similar contrivance, and at its other end carries a friction roller 158, which is adapted to engage a stationary cam 159 projecting from the under side of the head 3 immediately behind each die 10 (see Figs. 12 and 13). As the head 3 revolves, after the die 10 has been depressed to cut a lift, the die carrying the lift is brought over the paste-pot at the same time that the cam surface 159 engages the roller 158, the latter operation causing the paste-applier to be brought in contact with the under side of the lift and apply paste thereto. As soon as the head has carried the cam 159 from over the roller the outer end of the bell-crank lever will fall, submerging the paste applier in the paste in the receptacle 15a.

In lieu of the spring 66 for elevating the plunger of each mold I may employ the construction shown in Figs. 15 and 16, in which a bracket-arm 160, secured on the frame member 132, has an upwardly projecting portion provided with a cam surface 161. The plunger 162 in this construction extends only a short distance below the mold, being supported and guided in a bearing 163 pro vided on the under side of the mold-carrying table 62 beneath the mold, and is provided on its lower end with a friction-roller 16% which is adapted to ride over the cam surface 161 in the rotation of the table 62. By this construction the plunger is positively raised, the roller reaching the highest point of the cam 161 as the mold reaches a point directly opposite the board 135. A friction screw 165, mounted in the bearing 163, engages the plunger 162 to prevent it from falling after its roller passes off of the cam and to insure that it shall descend step by step under pressure exerted thereon by the plunger of the die as the lifts are successively deposited on the plunger-head '70 and upon each other.

Each of the plungers 13, not containing a nail-driver, is provided with an aperture 166 to accommodate the plunger 8, and the plunger 8 is provided at a suitable distance from its lower end with a collar 167 for depressing the plunger of the die.

In the use of the ordinary heel building machine the operator is given a specification of the heel to be built, which specification designates the size and thickness of each lift to be used in building the heel, so that a given number of heels of uniform height and configuration may be built; and the operator selects the various lifts from receptacles containing the same placed within'his reach. In the use of the present machine the operator will be supplied with the same specification, but instead of selecting lifts, he selects the leather from which the lifts are to be out. Thus, if No. 1 lift is specified as of an inch in thickness, he would select a piece of leather of approximately this thickness and place it under N0. 1 die and operate the machine to cut the lift therefrom. If No. 2 lift is specified as being of an inch in thickness he would select a piece of leather of this thickness and cut a lift therefrom by actuating No. 2 die. In selecting the leather from which to cut the lifts the operator is guided entirely by his eyes. The pointer 14:, however, will indicate on the 'age the thickness of the lift that has been cut. If a lift is required and the gage shows that the lift out is only 1 of an inch in thickness, the operator would select a piece of leather inch in thickness and cut it with the same die containing the e inch lift, thereby completing the thickness required for this particular layer. If, say, a -linch lift is required and the leather selected should be of an inch in thickness, the next lift would be cut from leather of an inch less in thickness than called for by the specification. Men engaged in selecting leather soon become very expert, and the cutting of a lift of less or greater thickness than that called for by the specification would, in nearly all cases, be the result of inadvertence or carelessness. By the exercise of reasonable care a skilled operator can invariably select a piece of leather of the thickness desired from which to cut the lift.

Having thus outlined the manner in which the lifts are selected and cut, I will now proceed to explain consecutively the operations of the machine in building a heel. The leather selected is placed on the cutting blcck 125 and the operator presses down on the lever 50, thereby transferring the driving belt to the fast pulley and operating the'shaft 44:. This causes the outer end of rod 41 to rise and the hammer 40 to descend on the die 10, thereby forcing said die downward and cutting the lift. After the lift is cut the plunger 13 will be proportionately raised, the pointer 1a indicating the thickness of the lift out, and the operator proceeding in the manner above set forth should the lift be of less thickness than that called for by the specification. The lift being of the proper thickness the operator next presses outward the lever 85 so that by the engagement of the pin 119 with the hook 89 of the lever 85 the arm 88 will be caused to partly rotate the shaft 76,thereby through the medium of the ratchet 79, causing the head 3 to be given a partial revolution on the column 2. This will bring the die containing the lift out over one of the molds of the mold-carrying table 62, but in passing to this position the die will have passed over the paste-pot 15d and the lift cut will have paste applied thereto in the manner previously described. Die No. 2 being over the cutting block, a second lift is cut in the same manner. In this operation theplunger 8 passes into the aperture 166 of the plunger 18 and the collar 167wvill engage saidplunger to depress it and cause it to deposit the I cut lift on the plunger-head 70, thereby causing the plunger to be depressed in the mold a short distance against the resistance of the spring 66. These operations are repeated until the last lift of the heel is placed in the mold, When the die shown in Fig. 6 containing the nail-driver Will be over the mold. The operator then drops a nail in the aperture 29, and when the next lift is cut. by No. 1 die the plunger 8 Will be depressed; to engage the nail-driver 27 and thereby. force the nail through the compiled lifts in the mold. When this has been done the operator then presses the lever 91 outward so that the crank-pin 108 will engage the hook 98 of said lever so that thearm will be caused to partly rotate the shaft 9a: and thereby, through the medium of the ratchet 115, impart a quarter of a revolution to the mold-carrying table 62. During this movement of the mold-carrying table the arm 72 will engage the lug 13a to release the pawl from engagement with the teeth of the plunger 65, thereby allowing said plunger to rise anddischarge the heel from the mold. During this movement also one of the striker-arms 143 will have pressed back the s 'iring-pressed bar 139 carrying the puslrplate 1&6, and as the mold arrives opposite the board 135 the striker -arm passes into the groove142 of the arm 1 11, allowing the spring 14:0 to expand to move the push-platetoward the board, and thereby transfer the heel from the mold-carrying table to the board As soon as one compartment of the board 135 is filled with heels it is moved by manipulating the lever 151. to bring an empty compartment into position to receive the heels discharged from prising a mold, a lift-cutter movable in a horizontal plane to a position over the mold, and means for discharging the cut lifts from the cutter into said mold.
