Specification of Letters Patent.

Patented June 25, 1912.

To all whom it may concern:

, Be it known that I, THOMAS K. Kni'rn, of Boston, county of Suffolk, State of Mas sachusetts, have invented an Improvement in Lasting-Machines, of which the following description, in connection with the accompanying drawings, is a specificatioinlike letters on the drawings representing like parts.

This invention relates to machines for use in the manufacture of boots and shoes and is herein shown as embodied in a machine for lasting shoes.

An object of the invention is to provide a machine with the aid of which the manufacture of shoes can be carried on more rapidly than with prior machines and, partly with the same object in view, to reduce the labor by making the machine to perform automatically certain portions of the work now generally requiring more or less special attention. and labor from the operator.

Important features of this invention consist in means for lasting the heel and toe of a shoe while the shoe occupies one position, means for lasting the sides with the shoe in a different position, and a shoe support movable with the shoe from one to the other position; toe and heel lasting mechanisms which are separable to permit the introduction and removal of a shoe and a shoe support which is movable with a shoe thereon into and out of position between said end lasting mechanisms; an end lasting mechanism which is movable downwardly to press and flatten the overwiped upper hard down upon the last bottom and which is automatically advanced farther over the shoe as it is moveddownwardly; the provision of a movable carrier having a plurality of shoe supports and mounted, with relation to end lasting mechanisms and to automatic or other side lasting mechanism, for movement to carry a shoe away from the end lasting mechanisms and to present that shoe to the action of the side lasting mechanism while presenting a second support in place between the vacated end lasting mechanisms by which another shoe shall be operated upon; the provision of a side lasting device, which may be a wiper that can be used all around the shoe, or a fastening mechanism, orboth a lasting device and a fastening mechanism, and mechanism for operating the same and giving thereto traveling movements to act on different portions of the shoe successively; the provision of mechanism for giving to a shoe support rotative movements while the toe and heel are being operated upon in combination with means to suspend such movements during operation on the sides of the shoe by traveling lasting means or fastening means; the provision of means to reverse, while the shoe is being turned at the heel or-toe, the direct-ion in which a lasting or fastening mechanism has moved while operating on a side of the shoe whereby said mechanism is carried back toits starting position for side lasting; the provision that a device with a lasting or beating function is advanced under downward pressure and caused to treat the upper by impact when or after it reaches the edge of the shoe; the provision that a lasting or fastening device is actuated automatically in a closed path in which it slides forwardly over the upper, and then rises and retreats to avoid drag on the upper during its return movement.

The foregoing and other features ofthe invention, the importance of which is notto be considered as prejudiced by the fact that they are not here specifically mentioned, together with certain details of construction and combinations of parts will appear in connection with the following description of the machine which is illustrated for exemplification of the invention, and will then be particularly pointed out in the claims, reference being had also to divisional applications 589,6S1 and 639,979 in which are to be found the claims to the automatically operated tacker with its attached upper wiping foot and the claims to the end lasting mechanism per 86, as distinguished from the combination claims comprised in this application.

Fig. 18 is an enlarged sectional detail of the toe-lasting devices, the section being taken longitudinally through the arm 8 the studs and 71 and cooperating parts; and Fig. 19 shows one of the slides 8 de tached to show its two holes.

The framework shown consists chiefly of a base A having two fixed posts or columns A, A and standards A A The standards A carry bearings for the main shaft A and the standards A, bearings for the auxiliary shaft F. The post A has secured to its upper end by bolts B a plate B. The post A also supports brackets B which have bearings for a rock-shaft B provided with an upwardly extended arm B having at its upper end ahole in which enters loosely a stud B carried by a yoke 13, see Fig. 2 the ears of said yoke supporting a stud B that passes through ears at the lower side of the tacker bed B The tacker bed carries upon its upper side standards B and 13 The standards B have bearings for the tacker actuating shaft C, provided at one end with a sprocket wheel C over which is extended a sprocket chain C said chain embracing a sprocket wheel C mounted on a stud C and having an attached sprocket wheel C over which is extended a sprocket chain C driven from a sprocket wheel C, fast on the main shaft, said shaft C having cams C C and C The standard B has a stud D on which are mounted three levers D, D D see Fig. 3.

The lever D, actuated by the cam G is designated as the driver lever; it raises the driver D in the tacker head D through the links D", D and lever D the lever D being mounted on a swinging link D pivoted at a, see Fig. 2; a spring D connected with'the lever D and with a stud a fast on the link D serves to depress the driver bar quickly whenever the roller stud a on the driver lever arrives at the abrupt end of the cam C The driver bar has a driver a guided in the nose a of the tacker head.

the head of the tack and drives it from between the pins out through the nose into the stock, the pins at such time yielding under the action of the springs a and permitting the driver to pass between said pins. The upper end of the link D, referred to, is entered by a stud a see Fig. 2, which ex tends from a collar a fastened to the upper end of the driver bar by a set screw a see Figs. 3 and 8.

The driver-bar, see F ig. 8, has secured thereto, by a set screw (4 a collar 1) having a projecting pin 6, that enters an irregular slot 6 in a pick-off lever 6 pivoted at 5*, the lower end of said lever, located at the end of the raceway b see Fig. 17, having an open notch 2, the walls surrounding said notch receiving and supporting the head of the endmost tack of those coming down the raceway b, the movement of said lever Z2 in the direction of the arrow Fig. 17, cansing it to take the tack in its notch, carry the same laterally and put its pointed end within the open end of a tack guide 6 said tack guide leading the tack into the tacker head, the head of the tack resting in the pick-off tack pocket formed by the grooved ends of pins (4 the driver bar being then lifted.

The tacks to be driven are supplied to a feeding bin 1) and are led thence through a tube 6 to a hopper b from which they pass to the raceway 6 Those tacks which arrive in the hopper with their points properly directed downwardly enter the slot in the upper end of the raceway, while those tacks which enter the hopper head first fall below the receiving end of the raceway and drop on the top of an inclined bar 0, and slide down said bar into a basin or receptacle 0, see Fig. 5, from which they are returned from time to time into the bin 6 The lever derives its movements by the rising and falling of the driver bar.

The tube 5 see Fig. 6, is slotted near its lower end at 3 to let the tacks sliding down said tube drop therefrom and enter the hopper. The tacks are permitted to escape from this tube only at intervals, the tube having a gate 0 which enters a vertical slot crosswise of the tube, as best shown in Fig. 6, said gate being normally closed by a suitable spring 0 connected at one end to said gate, and at its other end to a suitable pin 0*. The gate 0 is opened at intervals by a gate Opener 0 shown as a finger pivotally mounted on one end of the stud a, before described, held in a forward projection of the tacker bed B The gate opener has near its upper end a slot, see Fig. 5, which receives a pin 0 extended from the side of the hopper, said pin tending to keep the gate opener in proper working position, but permitting the hopper to rise and fall as the tacker is put into and out of operative position as required.

The tacker head has a backwardly extended arm E sustained on a stud E at the upper end of link D", said arm being turned about said stud by means of lever D having at its inner end an attached arm d, see Fig. 3, provided at one end with a slot which receives a stud cl extended fro-m the side of arm E. The tacker head is moved laterally by swinging the link D through lever D see Fig. 3, having at its inner end a pin (Z that enters a slot at one end of an arm (Z fastened to said link. The levers D and D move the tacker head forward and lower the same into position so that the driver bar may be operated to drive tacks into the edge of an upper laid over upon the inner sole by the lasting devices and clamped in position to receive tacks, and move said tacker head backwardly out of operative position after the tack has been driven. While the tacking means is operating to drive tacks automatically about the shoe to confine the up per to the inner sole, the operator will be devoting his time to removing from the jack the lasted shoe previously tacked, and to putting another last having a shoe upper thereon in place and preparing the same to be tacked after the jack has been moved and the prepared shoe brought into operative re lation tothe tacking means.

The tacker head, see Fig. 5, has a forwardly extended edge gage or feeler E against which bears and moves the flanged guiding edges of the side clamps 5, and the guiding flanges 6 and 7 of the toe and heel clamps f, f. The tacker head has an upper wiping foot or member E*, which, when the said head is being put int-o working position, is adapted to strike the said clamps and sliding thereon let the head come gradually into working position. The flanged edges of the side clamps are carried by two arms (Z mounted loosely on a rod d mounted in ears d of a revolving base plate al said arms having each a finger (Z66, the arms at opposite sides of the base plate being connected by suitable springs (Z Upon the rods 61 are also mounted two pairs of levers e one pair at each side of the last. These levers are best shown in Fig. 1 where the levers (Z referred to are represented as broken off. Suitable springs 0 act on the short arms of the levers e and normally keep the opposite ends thereof, which are preferably provided with friction surfaces or pads e pressed against the upper at the sides of the last near the bottom thereof. The levers e at opposite sides of the last are united by links 10 with actuating levers 6 so that by raising the free ends of said actuating levers said two sets of levers may be moved away from the last, and as said levers are so moved they act on the fingers d, see Fig. 2, of the arms (Z and carry said arms and the Tide clamps 5 away from the upper on the ast.

The heel and toe clamps f, f, herein shown as composed of metallic straps hinged to gether centrally, see Figs. 1 and 3, have respectively at their upper ends guiding flanges 6, 7, shaped to conform to the shape of the last at the junction of its sides and bottom about the heel and toe ends thereof. The ends of these heel and toe clamps have studs on which are fitted the ends of like links f each jointed at its opposite end to the upper end of an arm or lever f said arms being each mounted loosely on rods f held in ears f, so as to be turned about said pivots ,when the toe and heel clamps are to be removed from contact with the heel and toe of the shoe. This removal of the heel and toe clamp is effected simultaneously by means of a link f, f, the part f" being made as a yoke, and the part f being threaded, see Fig. 15, to receive a nut f, the shank of the said nutracting against a crossbar f uniting the two like links f at that end of the machine.

The machine is provided with two similar base plates cl each sustaining similar side clamps and heel and toe clamps. Each base plate has attached thereto a ratchet wheel g, but as these are alike, I need herein specifically describe but one of them. Each of these ratchet wheels has a hub or spindle g, which is extended through a suitable hole in a pivotally mounted carrier on the column A said column having at its upper end a stud 9 see Fig. 11 that enters a hole in the underside of said carrier 9 balls or rolls 9 being applied between the top of said post and the underside of said carrier to constitute a ball bearing. These base plates are rotated while the tacker is working to drive tacks in the upper about the heel and toe thereof and while the upper along the sides of the last is being tacked to the inner sole, the foot plates remain at rest andthe tacker head is moved longitudinally with relation to the stationary last, as will be described. The teeth of the ratchet wheels 9 are engaged while the jack is being rotated, by a pawl 9 pivoted at g on the short arm of a lever g pivoted at 12, one end of said pawl being acted upon by a spring 13, connected at one end to said lever 9 While the pawl is acting to turn the base plate and the last during the insertion of tacks about the toe and heel of the upper,

the end of the pawl is permitted to engage the teeth of the ratchet wheel, said pawl acting intermittingly to impart to said ratchet wheel a partial rotation, the lever 9 during such operation, being struck, after the driving of each tack, by the upper end of a lever g see Fig. I, mounted on a stud 9 fixed to the post A said lever being acted upon by a cam 9 on the main shaft, a spring serving to keep the end of said lever against said cam. This lever acts continually, and it will move either one of the two like levers whichever may be brought by the movement of the carrier 9 into its range of movement, but'when the edge of the upper along the side of the last is to be tacked, and the ratchet wheel on the base plate is to stand still while some tacks are driven, then the effective motion of the pawl is stopped by or through a pawl controller it, shown as a lever pivoted at h,one end of the said pawl controller being at such time.

acted upon by a. cam 72 see Figs. 3 and 4-, fast to a ratchet wheel 72?, turning on a stud screw 14, screwed into a threaded hole 15, see Fig. 11, in the stud g. The ratchet wheel 7L will have in practice a tooth for each tack to be driven in going completely about a shoe, and the number of its teeth corresponds with the number of teeth of the ratchet wheel li to be described. The ratchet wheel h is moved one tooth at a time by the pawl 16 carried by the lever lVhen the projections of the cam 72 act to move the cam controllers said controllers are moved outwardly so that they operate on and put the acting ear of the pawl out of position with relation to the teeth of the ratchet wheel g. Each lever is moved on its back stroke by a suitable spring 9. Each hub or spindle g is provided below the carrier 9 with a collar 17 on which rests a friction device 18, shown as a spring, and the lower end of said hub has a recess see Fig. 7, in which may enter a locking device 19, shown as a bolt attached to a lever m, pivoted at m on a slotted cross bar m supportedby the post A an arm of said lever having connected to it a rod m having an adjustable nut or stop 777/, said stop being so located that when the treadle m is depressed by the foot of the operator the said rod will be drawn'down to withdraw the locking device 19 and leave the hub free to allow the carrier to be turned. The lever m is fixed by a suit-able screw 22, on a collar 23 surrounding loosely the main shaft. The spring 24, see Fig. 1, acts normally to raise the lever m so that whenever a hub g comes in position over the said locking device the latter will be first acted upon by the beveled end of the hub, and then the locking device will enter the recess at the end of the hub. The lever m, Fig. l, performs a second purpose, that is, it has connected to its nner end a shouldered link m, which, when the operator puts his foot on the said treadle, rises, and acting on the arm m fast on the rock shaft B turns said shaft and carries the tacker head backwardly so that the tacker may be carried out of'operat-ive position while the carrier 9 is being rotated partially from one into its other po sition.

To give to the tacker head its longitudinal reciprocation in one direction while the side edges of the upper are being tacked, and in the opposite direction while the heel and toe of the upper are being tacked, I have provided the tacker bed plate B with an arm u, see Fig. 3, and to this arm by a stud a, I connect one end of a link W, the opposite end of said link, being extended across the tacker bed plate and being provided with an adjustable stud 11 which enters a slot a in a lever n pivoted on the plate B at a. The opposite or free end of the lever 12 has mounted on it pivotally a block W, see Figs. 3 and 9, to which by a pin a is joined one end of a link n, entering a loose block 11 having a shank, see Fig. 9, which enters a hole in the upper end of a lever n mounted on a stud 11 in the post A. The short arm of the lever 71 is extended outwardly over an auxiliary lifting device 0, pivoted at 26, on a stand 27, the free end of said auxiliary lever having a stud or projection 28 which rests on the periphery of a cam F, fast on the auxiliary shaft F, said lever being kept in contact with said cam by a spring a, said shaft carrying the ratchet wheel h (Fig. 2), which is acted upon by a suitable pawl 29, pivoted on a pawl carrier 30-mounted loosely on the shaft F, and having connected to it a link 31, attached by a screw 32 to a cross slide 33 made adjustable in a groove of a disk 34 fast on the end of the main shaft.

The ratchet wheel it has a tooth for each nail to be driven, and it is rotated once during the lasting of each shoe, and the cam F, acting on the levers 0 and 12. and said spring 11 causes the lever 11- to be moved first in one and then in the opposite direction, and in so doing, acting on the link 71 moves the tacker head first in one and then in the opposite direction.

The tacking of the upper will be commenced at the shank, see Fig. 3, while the foot plate is held stationary and thereafter the tacker will be made to travel in the direction of the arrow following the contour of the last and shoe, Fig. 3, until the curved part of the toe of the upper of the shoe on the last is in position to be tacked, at which time the rotation of the foot plate will be commenced and at the same time the traveling movement of the tacker bed plate and tacker will be reversed and moved step by step, and will arrive at its starting position as the foot-plate completes a semi-rotation to effect the tacking of the toe. Then while the foot plate is held at rest the tacker bed plate will be again moved in the direction of the arrow 80 to insure the driving of tacks along the other side of the shoe from the toe tothe heel, and when the tacker comes to the curved part of the heel the rotation of the foot plate will be again commenced and the bed plate of the tacker will be again started backward on its return movement. The cam F is so shaped as to move the lever a two complete strokes during the lasting of each shoe. The auxiliary shaft F, see Figs. 1 and 14, has at one end a cam 79, which acts on a lever p, pivoted at p on a stand p and the opposite or right hand end of said lever has a pivoted detent p to which is connected a suitable spring 36, the springacting to keep the said link 79 against a stop 37, and with the free end of the said link under a projection 38 of a pronged lever 39, pivoted on a collar 40 fast to a slide rod 41 having at its upper end a handle i The rod, see Fig. 3, has co-acting wit-h it a locking device 6 under the control of a spring Z).

Viewing Fig. 14, the prong of the lever 39 is shown as acting against and holding the upper end of an elbow lever 42, mounted loosely on the main shaft A swung to the left in which position the pulley G will be fast on the main shaft A The opposite end of the elbow lever has a pin or projection 43 which acts against a cam surface 44 on a second lever 45, pivoted at 46, and acted upon by a suitable spring 47 which, when free to act, willturn the said lever over to ward the right.

The main shaft will be stopped whenever the heel of cam 10 passes from under the pin at the end of the lever p, which may be obviously depressed by a suitable weight or spring. The movement of the other end of the said lever lifts the pronged lever 39 and frees the elbow lever 42 thus enabling the lever 45 to be turned by the spring 47, to bring its inclined upper end, see Fig. 3, against the end of a latch 48, which is thereby moved to one side and freed from engagement with one of the teeth on the inside face of the hub of the pulley G which is.

loose on the main shaft A This clutch pulley is old, but the addition to it of the lever 39 to throw it out of operation automatically is, I believe, of my invention, no claim however is made to this invention in the present case.

The base plate, see Figs. 12 and 15 has two guides 50 spaced apart to form between them a way in which is located the foot 51 of a toe rest 52, the foot having a pawl 53 to engage one of a series of ratchet teeth 54 to hold the toe rest in any position into which it may be adjusted. The upper end of the lever 9 see Figs. 3 and 16, has fixed on it by a set screw 9 a finger 9 on which is pivotally mounted a pawl 9, said pawl being normally held up by a spring 5/, see Fig. 16, against a stop 57 to keep the end of said pawl in position to act against the pawl carrier 9 see Fig. 3, and turn said pawl carrier at each movement of said lever 9 When the carrier 9 is moved to take a tacked shoe from tacking position, and to place in position the other jack holding a shoe prepared to be tacked, the pawl carrying lever g for cooperating with the jack being placed into tacking position will meet the upheld pawl g and sliding over it will depress said pawl, the spring 9 enabling the pawl 9 to rise and stand in correct operative position with relation to the pawl carrying lever 9 The cross bar m 'has near its ends suitable slots 1" in which are placed like levers 1", pivoted at r to treadles r fulcrumed at 7, said levers being normally held up by suitable springs T The upper ends of these levers r are forked to present ears which receive pins 1*, said pins entering suitable lugs r at the undersides of plates a said plates each having a leg 7'", adapted to rest on a shoulder or projection 7 of the lever r, said leg being adjustable vertically on said plate to thereby determine the inclination of said plate to corre spend with the bottom of the toe or heel of the last. The top of the plate 1 has two like cars 60 carrying a pin 61, which also passes through two cars 62 extended from the lower side of like frames 8, so that said frames 8, having shoulders 100, see Fig. 1,

may tip on said pins about an axis in the line of the direction of the length of the last. These frames 5, both alike, have each secured to them by screws 20 a top plate 8', see Fig. 13, provided with

slots

65, 66 and 67, and screw receiving slots 69, the front ends of the plates s being provided with a U-shaped space to conform substantially to the contour of the last at its too and heel. Under the plates 8 and resting on the shoulders 100 are placed the toe and heel lasting slides s 8 made each independent of the other. The lasting slides 8 shown partially in Fig. 3 and in Fig. 19 where one slide is represented detached, have each two holes 120, 121, instead of a stud and a curved slot, as heretofore common. Suitable guides 7 9 connected to the plate 8 overlap the links .9 and aid in keeping them on the plate 8. After the upper to be lasted has been put on the last, the last will be put on the heel pin t, pivoted on the rod f and the toe end of the last will be laid on the toe rest. In this condition the heel and toe clamps will be made to fit the 'heel and toe of the last by turning the nut f and the inner sole will be laid on the bottom of the last within the edges of the upper, and then the levers 6 will be turned to let the arms 6 meet the upper lying against the sides of the last and press said upper close to the last. The movement of the arms 6 against the last permits the springs d to draw the arms d toward the last and place the guiding flanges of the clamps 5 against the upper along the side edges of the last in line with the guiding flanges 6 and 7 of the toe and heel clamps. The operator now by suitable pincersmay engage the edges of the upper and draw them above the inner sole to take out any stretch and fit the upper to the last, and then .he will move the levers 2" each toward the last in a slot 9*, and he will cause the 'U-shaped ends of the plates .9 to be carried forward to stand just above the heel and toe clamps. A suitable pawl, as 80*, carried by each of said levers r engages the ratchet teeth 81 on the cross bar m and holds the levers 1" in their adjusted positions. This having been done the operator engages first one and then the other of the like levers 77, and moves the slides s forward into the position shown in Fig. 3, said slides having given to them, due to the shape of the slots and 66 in which the pins 70 and 71 travel, a combined forward and inward movement so that they will act on the edge of the upper and by pressure thereon in radial linesfrom the center of the circle of the heel and toe will lay the said edges snugly over the inner sole.

The slides and their actuating mechanism constitute what may be designated as the lasting devices, and they having been moved to lay the edges of the upper over on the inner sole and press the same in place, the operator withdraws the slides and then raises the pawls SO and turns the levers r to throw them apart leaving the shoe on the jack with its upper held at sides and toe and heel by the side and toe and heel clamps. The jack may now be moved into position under the tacking head to have the upper tacked in place.

In this machine two operations can go on simultaneously, viz :tacking and preparing for tacking. The tacker head is held in working position against the face of the guide 7 by the action of a weight 75 and cord L. It being desired to start the machine in operation, the main shaft being at rest, the operator will engage the locking device 27*, turn the same from its engagement with the rod 41, and thereafter by grasping the handle t, will push the rod in a direction opposite to that of the arrow near it in Fig. 14:, and start the tacking operation, it being thereafter carried 011 automatically until the upper has been tacked all about, when the machine will be automatically stopped. The

base plate (Z and its parts to sustain the last are designated herein as the jack. The tack inghead constitutes one form of tacking means for uniting the lasted upper to the inner sole, but this invention is not limited to the exact shape and construction of the parts so far described, and instead of them I may use any equivalent or well known de vices, the gist of this invention lying in means to support or carry a plurality of jacks, means to hold the uppers pressed against the lasts mounted on said jacks and means to secure the lasted upper to the inner sole the said lasting devices and upper securing means being separated one from the other so that .one of said jacks with a shoe on its last may be presented to the lasting devices and then to the means for securing the upper to the inner sole, thus enabling these operations to be carried on simultaneously.

In operation the nose of the tacker head has imparted to it, by the levers with which it is connected, peculiar motions during the insertion of each tack, that is, the head is lowered at the outer side of the edges of the upper, and the nose meets the clamps and slides across the same onto the overturned edge of the upper to tack it to the inner sole, and then the tacker head is lifted from the upper and is carried upwardly and back wardly into its inoperative position, after which latter movement the necessary change of relative positionof the head and jack are made preparatory to driving a second tack, and then the head'is again moved over onto the upper as before. In this way the tacker head has given to it four motions. When the last is being changed on a jack and the shoe is being prepared for lasting, the ratchet wheel 9 is held stationary by a pin 10 at the end of an elbow lever to, pivoted on an ear of the carrier 9 A suitable detent e0 acts to engage the teeth of the wheel 'to prevent it from being rotated in the wrong direction. The hopper b has attached to it an extension chute C30 and tacks which drop onto the inclined bottom of the hopper slide off therefrom into the chute and enter the receptacle 0'. i

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is V 1.
