5 t; 07/ ctr/1mm it may concern:

lie it known that I, EIHIGNE L. KnYEs, a

citizen of the United States, residing at ioston, in the county of Suttolk and State of Massachusetts, have invented certain lmprovements in Welt-Butt -'l aeking Machines, of which the following description, in eonnectitm with the accompanying drawings, in a specification. like reference characters on the drawings indicating like parts in the several tigures.

This invention relates to machines for use in the manufacture of boots and shoes as, for example to lasting and tacking machines, and is embodied in a machine for tightening a welted shoe to the last adjacent to the end of the heel seat and fastening it.

Objects of this invention are to increase the speed and etliciency and reduce the labor required to operate some machines heretofore proptsed for this work, including the machine of my prior application Serial No. 2.90529, filed Oct. 28, 1907.

An important feature of this invention consists in the provision of novel means for tightening and holding the shoe stock in position to be fastened including, if desired, means for locking the tightening mechanism. This is shown as including oppositely disposed shoe engaging or clamping members, each of which is arranged to engage the shoe at the upper and lower edges of the heel stitlener for forcing the sides of this portion of the shoe snugly to the last. The lower portions of the engaging members clamp the sides of the shoe first at a point some distance below the insole and act upwardly and inwardly to gather the fullness of the upper and force it toward the insole, while the upper portions of the en gaging members are formed to engage in the welt: criase under the end portions of the welt to take up the fullnes in the stock developed by the lower clamping members and to tighten the stock over the last edge by pressure against the welt and the upper and, it may be, against the stitches of the inseam which said member may be shaped to engage in the crease. The opposed clamps are connected for operation together by means which is shown as manually actuated and, in one embmliment of the invention. a locking means is provided convenienttv arranged with relation to the actuator for manipulation in relation therewith.

Another very important feature of this invention is found in the provision for prescntation of different portions of the work alternately t0 the tacking mechanism. As shown, the work clamping device or holder, formed as above indicated or otherwise, is mounted and preferably guided relatively to a tacker for movement to present one tightened side of the shoe in position to be fastened and then to present; the opposite portion or side of the shoe while the stock continues to be held. ln the illustrated construction, the work holder is guided for transverse movement in the tacking machine. The shoe is yieldingly upheld upon a spindle which is raised in time relation to the tacking operation. After the Work clan'iping device or holder has been actuated to tighten the shoe to the last, the shoe is positioned with one side of its bottom, including the over-worked edge of the upper or the welt, or both, under the nozzle of the tacker and the treadle is then depressed to raise the shoe tirmly against the nozzle and then to start the tacker. A plurality of tacks may be driven if desired and then the work is sait'ted laterally to present the other side of the shoe bottom in position to be tacked.

A. further feature of the invention consists in provision for laterally positioning the movably supported shoe relatively to the tacker for the tacking operation. Preferably stops are employed which are positioned relatively to the shoe and are aringed to engage the machine as the shoe is moved transversely to determine the distance from the side edge of the shoe at which the tacks shall be driven.

The machine is so constructed and arranged that its use requires very light manual labor and a small degree of skill so that it can be tmerat-ed by a boy or other cheap tabor.

These and other features of this invention will be more fully explained in connection with the detailed description of the machine in which the invention is illustrated as embodied and will then be pointed out in the claims.

In the drawings :Figure 1 represents a machine embodying this inventii'ai in a preferred form; Fig. 2 represents the oscillatirg clamping device in perspective; Fig. i) represents the last; spindle in detail; Fig. it

represents a modified construction covered by my divisional application Serial No. (333,469, tiled June 16. loll; Fig. 5 represents in perspective, the clamping device of the modified construction; Fig. (i represents the presser-foot of the tacking machine and Fig. 7 is a section through the shoe and last in front of the clamping device showing the relative position of the clamps and the tacker when in operative position.

Referring to Fig. 1 A represents the standard of a tacking machine of common type, a description of which is found in United States Patent No. 389.2%, granted September 11, 1888, and need not be given herein except in general. 2 is a tack hopper and tack arranging and feeding device, a: one clutch member and (3 is the driving pulley which forms the second clutch member, 8 is the clutch operating lever, and 10 is a cam which acts on a lever 12. which is fulcrumed at l-l. On the lever is pivoted a lever 16, the left hand arm of which is: forced upward by a spring 18 and rests against a block 20 on the clutch lever 8. The block 20 is engaged by a. shoulder on the lever 16 and when this lever is displaced lengthwise to the left by the cam 10 and lever 12, the clutch is thrown out. The cam 10 timed to throw out the clutch just b fore the tack is driven so that, when the clutch is thrown in by depressing the left hand end of the lever 16 so as to disengage the shoulder thereon from the block 2() the tack will be immediately driven. The lever is depressed by means of a spring-pressml dog 22 attached to a. rod 24 leading to lever 26 and treadle lever 28. 'hen the treadle is depressed the dog engages a projection on the lever 16 and depresses it, thus permitting a spring 11 to throw the clutch in.

The means whereby the shoe is supported and the parts pressed into position to be fastened by tacks from a nozzle 30 are mounted on a pivoted support. including the member 42, capable of limited oscillation to bring the opposite sides of the shoe alternately under the tacker. Referring to these parts more in detail a block Ell is rigidly clamped to the standard A. In a groove in the front. face of the, block slides a bar 36 which is connected at its lower end by a rod 38 with the treadle lever mechanism and at its upper end has a bolt 40 rigidly secured therein on which is pivoted for limited oscillation, the support 42 of the shoe clamping means. Referring now particularly to Fig. 2, it will be seen that the bar 36 has beveled edges and slides in corresponding ways in the block 3-} so that it cannot be displaced laterally. The head of the bolt 40 is provided with a slot in which in erted a downwardly extending tongue ll. Opposite. to the lower end of the tongue ll rods 40 are threaded through ribs eh") on the support 42 and are provided with thumb lock nuts l8. The support which holds the shoe is thus mounted to oscillate on the bolt all) about a center which preferably is substantially the center of curvature of the average shoe shank near the heel breast line to an extent determined by the adjustment of the stop rods 46. ,ly this construction the shoe support may be given a sidewise movement in a curved path corresponding to the average curvature of the shanks of shoes about the pivot. of the support to bring the sides of the shoe alternately into operative rein-- tion to the tacker and the shoe presented at a predetermined angular relation to the tacker, so that the tacks will be driven in a direction inclined in ardly from the edge of the last. Upon the top of the support 122 are bosses 50, 50 on opposite sides and a boss between them. On the bosses 50., 50 are fulcrunied levers 5t, at by tap bolts 56, at). Power is applied to the levers by a pin and slot connection between the rear ends of the levers and blocks 58 which are moved toward and from the central boss 52 by means of a right and left threaded screw 0 which is rotated rapidly by means of small. and large gears (32 and (H and a hand wheel ('16 in a manner obvious from inspection of Fig. 2. The middle unthreaded portion of the right and left screw tit) is journaled in the boss and means is provided for prevent ing longitudinal movement. of the screw therein. In the boss above the journal of the screw and at right; angles thereto is mounted the stem 8 of a back rest T0. The stem of the rest slides freely through the boss 52 and is normally held forward by a. spring 72.

()n the forward ends of the levers 54 are shoe engaging clamps 74 which are pivoted to blocks 76 by horizontal pins 78, the blocks being in turn pivoted to the levers it by vertical bolts 80. In this manner limited universal movement is provided for the clamps Tl with respect to the levers Leaf springs 82 are fastened at one end by the bolts 80 to the under sides of the blocks ((3 and their free ends engage the lower ends of the clamps Tl to force them toward each other. Springs 84 (Fig. l) are attached to the under side of levers St and to the inner part of the clamps, to keep the clamps in normal position facing inwardly shown. The inner sides of the clamps are shaped to grasp a shoe about the rear shank portion and have pads 86 of some material which will not injure the finish of the leather of the shoe. The pads how yet do not extend the whole length of the clamps but stop short of inwardly projecting portions 88 on the upper ends of the clamps; these rigid portions are formed to enter the well: crease of a welted shoe and serve to force the welt and adjacent parts firmly together near the point of nailing and to position or locate the welt butts for the tacks to be inserted therein. As the padded lower ends of the clamping members Tet are pressed inwardly by the springs 82 they engage the upper first at a point considerably below the insole and press and smooth it upwardly and inwardly against the last as they close until finally the rigid upper ends 88 of the clamps engage the upper in the welt crease and force it lirmly in over the insole. By this means the upper drawn tightly over the last and into position to be tacked in place.

In the prior constructions of which I am aware there has been a tendency for the welt locating blades to lift the stock and hold it away from the last bottom at the tacking point. Pressure of the lower ends of the devices 74 against the side of the shoe insures a downward component of pressure by the crease engaging ends 88 while said ends are pressing inwardly against the stock of the welt seam, thereby obviating the objectionable lifting of the stock which accompanies the use of other constructions.

To provide for slight movement of the shoe so that it is free to be clamped in position for tacking, the spindle SE) of the jack is pivoted (Fig. 3) in the bifurcated end of a jack rod 90. Below the pivot of the spindle a notch 92 is provided in which is seated, normally, a spring pressed pin 941. In this way the spindle is held upright but is capable of being moved to a limited ex tent from side to side. The jack rod 50 slides in a sleeve 96 which is pivoted at 98 to the base of the support. To the lower end of the sleeve 96 is pivoted at 99 a jacl; lever 100 which is pivoted to the jack rod 90 at 97, a slot in the sleeve 96 accommodating the pivot pin. The lever 100 is held in depressed position with the rod 90 raised by a pawl 102 engaging a ratchet segmcrn 104 formed on the sleeve 96.

In the operation of this form of the machine the last with a welted shoe on it is placed on the spindle and elevated to the proper degree by depressing the lever 100. The hand wheel (56 is then operated to bring the clamps 74 simultaneously in toward the shoe which they engage first at a point remote from the bottom and press the mate ial inward, and toward the bottom, rocking meantime on the pivots 78 until the rigid fingers 88 engage the upper beneath the welt and tighten the upper and press the stock down upon the last bottom into position to be tacked. lVhen the shoe stock has been clamped with suflicicnt force in the proper position the support 45 is rocked to one side until one of the ships to engages the tongue 14-. This movement will, it the stopl-(S is properly adjusted, bring the margin of the shoe bottom in proper position under the tacker. The treadle 28 is now depressed to raise the jack so that the shoe is pressed against the nozzle of the tacker and to trip the clutch by depressing the lever 16 through the dog 22 and rod 34. Tripping the clutch starts the tacker into action and a tack is driven to secure the upper in tightened condition and it may also be to fasten the welt butt and the heel stiliener to the insole. The treadle is released during the first tacking operation and the cam 10 throws out the clutch and stops the machine as it is on the point of driving another tack leaving it ready for the next operation which occurs when the shoe jack is swung over against the other stop 46 and the pedal lever again depressed.

tcferring now to Figs. 4-, 5, (l and 7 in which a somewhat modified embodiment of the invention is shown, 150 is a jack rod which is slidingly mounted in a socket block 152 which is loosely pivoted at: 157 to the lever 26. Within the block 152 a spring lo t is provided for yieldingly pressing the rod upwardly. Excess movement of the jack about the loose joint 157 is prevented by a bracket 15o which embraces the jack rod and is bolted to the standard of the machine. The jack rod is in two parts connectcd l a collar 138 which is pinned to the lower part of the rod and threaded to the upper part so that the length of the rod may be adjusted by rotating either part relatively to the other.

The clamping means in this construction comprises spring lingers lot), bolted to levers 1H2, 103, and rigid plates [or which are pivotally mounted on the levers and hence may be disposed at the proper angular position to clamp the upper to the last. The lingers 100 are prctcrably covered with noirabrasive material. Lugs lot; on the levers carry adjustable stops 168 to engage the nozzle so of the tacking machine (see Fig. 7). The levers 102, 10; are pivoted at 170 to a block 171 and are provided with intermeshing toothed segments 1T2 whereby the clamping lingers are made to move simultaneously in opposite directions; the lever 163-) has a handle 171 for operating the clamping fingers and means is provided l'or locking the lingers in clamping position. This consists of a plate. 170 pivoted to the lever 162 at one end and at the other provided with a slot 178 through which passes a pin 180 on the lever 103. ()n the pin is pivoted eccentrically at 182 the bifurcated end of a catch lever 18* which is held in engaging position with the slotted plate 176 by a spring 180, the other end of which is attached to a pin 192 extending from the lever 16?). The lever 1M carries o'llset therefrom a thumb piece 188 disposed in convenient position to be engaged by the thumb of a hand of the operator while holding the handle 174'. By this means the clamp may be readily unlocked. A height gage 190 for the shoe is attached to the levers 162 and toil by a screw and hole and by a screw and slot respectively.

The clamping mechanism is attached to the machine standard for lateral sliding movement by the engagement of a T-shaped curved tongue on the block 171 with a corresponding groove in a plate 200 attached to the standard the curve of the tongue being taken from the pivot of the jack post 157 as a center. Springs .202 are attached to pins 201 and to the block 171 on each side of the machine and tend to hold the block in normal position. The pins 204 also serve as a pivot or hinge tor the plate 200 which moves about this pivot as the clamps are raised by the jack toward the taeker.

In Fig. (3 is shown the nozzle of the tacker detached. As shown the engaging surt'aee is ribbed or corrugated but it may be made smooth, it desired. The mode of operating this 'lorm ot device is substantially the same as that of the form previously described and an extended account thereof will therefore not be necessary.

The shoe is jacked in the usual manner and s 'ung in between the jaws of the clamp or holder which is closed thereon by operation of the handle li t. The tingers lot) press the upper and stitlener to the sides ot the last and then the rigid blocks lttt clamp the upper and heel stitl'ener firmly and hold it as in Fig. 7. The clamp is then locked by the action of the spring lot; upon the lever 1st. The shoe is now swungto one side until one of the stops ios engages the nozzle Ill) it the taeker. the curved tongue on the block lTl, during this movement. sliding in the block 200. The pedal lever its is now depressed and the tack driven as previously described. The operation is then repeated upon the other side ot the shoe.
