To all whom it may concern:

Be it known that I, WILLIAM A. BOND, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Use inthe Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a -specliication, like reference vcharacters on the drawings indicating like parts in the several figures.

This invention relates to organized machines for inserting fastenings for particular purposes and is herein shown as embodied in a machine for attaching a welt or rand to stock, the particular embodiment of the invention illustrated being intended for use in attaching unshaped rands to heels. The usual practice at the present time 1s to mold the rand strip in such manner as to give it a tendency to curve into approximately the outline of the heel face to whlch it is to be attached and then to attach the rand by means of an ordinary nailing or stapling machine. The molded rands attached in this manner are usually cut to lengths which approximate the length required for the average heel, but to insure proper fitting of the rand to the heel and convenient manipulation in the attaching operation the rands must be-cut to lengths somewhat greater than those actually required. Moreover, when rands are molded and attached in the manner described, it is necessary to project the edge vof the rand somewhat beyond the edge of the heel face in order that the rand may be given the same bevel as the heel during the heel trimming operation.

An object of the present invention is to provide a machine which will both facilitato the attachment of rands to heels and will also economize material and reducel the number of operations ordinarily performed upon therand. To this end the invention aims to provide a machine which will handle the rand strip before it is molded, which will permit the convenient attachment of this strip to the heel while fitting the edge of the strip exactly to the outline of the heel, :and

which will so place the rand upon the heel' that there is almost no waste in trimming the projecting ends and that the-edge may be inclined approximately to the bevel which will be given to the heel in the succeeding trimming operation, whereby the waste in trimming the edge of the rand will also be reduced to a minimum. The molding of this rand will be effected, according to the present invention, during the heel compressing operation.

The invention aims further to provide means for holding and feeding the heel during the rand attaching operation, which will -be substantially automatic, and which will coperate with rand guiding means in such manner as to require very little attention from the operator in tting the rand to the outline of the heel as successive portions thereof are attached to the heel.

The invention further, contemplates the provision of means for automatically stopping the insertion of fastenings when the attachment of the rand upon one heel has been completed, the provision of means for automatically trimming the projecting end of the rand and the provision of a Work holder which is adapted to receive one heel in position for starting the attachment of a second rand as the attachment of the rand to the preceding heel is completed. Besides the features of the invention above enumerated, the invention also contemplates a novel organization of the machine asa Whole, a novel cooperation of Work feeding and fastening inserting mechanisms, and novel means for controlling the operation of the fastening inserting mechanism.

The illustrated preferred embodiment of this invention comprises tacking mechanism of the type shown and described in United States'Letters Patent No, 389,275, granted an application of E. Woodward. Although fastening inserting mechanism forms a part of the organization contemplated in this invention, it will be understood that the particular kind of fastening inserting mechanism is not of the essence of the invention.

Referring to the drawings, a base 1 is provided for a tacking machine head and to this base is connected a bracket 3 which has formed therein a bearing 5 which, together with a bearing 7 on the base, supports a Ishaft 9. At one end of this shaft is a continuously running pulley 11 which operates to drive the shaft 9 by means of a Horton clutch 13, the clutch being controlled at the will of the operator by means of a casing 15 connected by a rod 17 with a treadle, not shown. r1`he shaft 9 operates mechanism for automatically presenting the work to be operated upon. This automatic presentation of the work consists of two principal mo-V tions, namely, the vertical reciprocation of the work to aetuate the tacking mechanism and the horizontal step-by-step feeding of the work for presenting the work in driving successive tacks.

rThe-vertical reci rocation of the work 1s effected by means o a crank pin 19 on the forward end of the driving shaft 9. This crank in is connected by a rock-shaft 23 to the lbwer end of a table supporting block 24 slidingly mounted in guide-ways in the bracket 3. The table supporting block 24 is coninem/te nected with a work table 27 by means of a rod 29 threaded into a block 31 carried by the work table. The block 31 is loosely con nected with the work table 27 and a spring 33 is interposed between the work table and the block whereby a cation of the work table may be edected to -accommodate work of varying thicknesses without adjusting the relative elevation of the work table in the table supporting block. When such adjustment becomes desirable, it may be effected by means of a hand wheel 35, keyed to the rod 29 and confined between the block 24 and a crossbar 37 of the block. lt will be seen that operation of the hand wheel will elevate or depress the block 31, which, in turn, will elevate or depress the spring supported work table 27. By this,y adjustment the limits of the uniform reciprocation of the work table produced by the eccentric crank may be located at greater or less proximity to the tacking mechanism.v

The table supporting block 24 and the lower portion of the work table 27 are held in the guideways in the bracket 3 by a cover plate 30.

To effect the step-by-step feeding motion of the work simultaneously with its vertical reciprocation, the shaft 9 is provided with a cam 39, which operates mechanism'supported by the bracket 3 to rotate intermittently a split shaft 41, Fig. 9. IThe mechanism for effecting this intermittent rotation consists of a block 43 having a slabbed end 45 upon which is mounted a cam roller 47 arranged to engage the cam 39, Rotation of thev cam e'ects a reciprocation of the block 43 against the tension of a spring 57 and through a rack 49 carried by the block 43 oscillates an annular segmental gear 51 carrying a roller clutch 53 which is operated by the actuation of the gear to intermittently rotate the split shaft 41. The split shaft 41 is provided at its upper end with a pronged feed wheel 55 arranged to engage the side of the heel and edect its step-by-step rotation into positions to be operated upon. The split construction of the shaft 41 allows the feed wheel 55 mounted thereon to reciprocate vertically with the work table 27 and thus maintain its engagement with the side of the heel while the gear 51 at the lower end of the shaft remains in the'same herir zontal lane. The amount of rotation of the feed w eel 55 may be controlled by the adjustment of a stop 59 operating in a slot 61 of the block 43. 'The position of this stop 59 in the slot 61 may be adjusted toward or from the cam by means of a knurled screw 63 and a set nut 65, the screw 63 being supported by ears 67 projecting from a bracket 69. It will be seen the amount of reciprocation of the block 43 and the rack 49 may be controlled whereby the amount of rotation of the feed wheel 55 slight vertical reciproe' that by this adjustment aaai may he adjusted to vary the distance between successive tacks placed in the work. The feed wheel is so timed with relation to the work table that its rotation occurs during the retreat of the table from tack driving position or during the latter part of one cycle of operation of the machine.

The work table 27 carries a slide 7l connected therewith by means of a dove-tailed tongue 83 operating in a dove-tailed groove 85. At the rear of the tongue 83 is a slot 87 which receives the lower end of a screw 89 projecting from the slide 71. The slide 71 is yieldingly maintained in position to keep the work in contact with pronged wheel 55 by a spring 73 located in a longitudinally extending hole in the tongue 83 and interposed between the work table 27 at one end and the end of the screw 89 on the slide 71 at its other end. A hand lever 75 is -pivoted on the work table and has a stepped end 77 which operates by means of a stud 79 to retract the slide 71 against the tension of the spring 73 and maintain it in retracted position when it becomes necessary to retract the work holder for any considerable time.

This slide 7l carries the mechanism for holding and clamping the heels to he operated upon and consists, see Fig. 6, of a plate 91 slotted to receive and turn about a stud 81 on the slide 71. The plate 91 is provided with guides 93 for clamp members 95 which may be transversely adjusted by means of a right and left adjusting screw 97 and holes 99 are provided in the top surface of these clamping members for the adjustment of pins 101. The heels to be operated upon are positioned on the support 95 with their breast face against the oppo-v site sides of a thin plate 103 and the pins 101 serve to prevent their lateral displacenient.l To prevent the upward displacement orl the heels the plate 103 is provided with a threaded extension 105 upon which is av knurled nut 107 that may be adjusted to limit the vertical movement of a yoke 109 which is slotted to lit the flat threaded eX- tension 105 to prevent its rotation and to keep it in vertical alinement with the heels. 1t will be seen that the yoke is capable of line vertical adjustment, by means of the nuty 107, for gaging the thicknesses of heels. Connected to the yoke 109 are hinged clamping levers 111 provided with rollers 113 which engage the heels and a spring 115 normally operates yieldingly to maintain said rollers and heels from upward displacement but yields sufficiently to allow heels to be inserted and removed from under the rollers without disturbing the adjustment of the knurled contact nut 107.

On the vertically reciprocating work table 27 is a yoke 125 connected thereto by means of bolts 127. An arm 131 extending over ,are

away from the heel surface.

the feed wheel 55 is adjustably held in the yoke 125 by a bolt 133. and carries a rand guiding roller 129, Fig. 9, which may be adjusted on the arm to position the randv with relation to the periphery of the heel to which it is to be attached and held in adjusted position by a set nut 138. Adjacent to the rand guiding roller 129 is a rand guide 143 adjustably secured on the work table 27 by a screw 139. rlhe peculiar arrangement of this rand guide is an important feature of this invention. 1t will be noticed that an upwardly extending rand guiding portion 137 of the guide posit-ions the rand with its thin edge uppermost or removed from the upper surface of the heel so that when the rand is fed to the tacking mechanism, the thin edge is above the surface of the heel to which it is being attached while the thicker outer 'edge of the rand rests upon the upper surface of the heel. Thus, with the insertion of the tack through the rand into the heel, an upwardly extending loop is formed of the thin edge of the rand between the tacks in that portion of the rand which is bent around 'the rear of the heel. lt will be seen in F ig. 11 that ordinarily where the rand. is fed to the tacking mechanism with its thin edge in the plane of the surface of the heel the thin inner edge 145 of the rand, when the rand is bent to conform to the curvature of the back' of the heel, may crumple at points where its folds will be caught by the tacks andv attened down to the heel surface. The thick outer portion 147 of the curved rand at this part of the heel has a tendency to turn upwardly and pull away from the heel due to the tension produced in it at this point. ln Fig. 10 a heel having' a rand attached by the inechanisniherein described is shown in which the loops 149 of the thin edge of the rand are all looped upwardly. Ilhese loops, when the rand is so tacked, forni braces which prevent the thick outer edge of the rand 147 from turning upwardly and This method .of attaching a rand also insures that the outer edge face of the rand will be kept in substantially parallel relation to the edge face of the heel, thereby facilitating trimming.

With the upward movement of the work support produced by the mechanism already described, the heel is brought, together with the rand which has been fed into position above it, into contact with a tacker nozzle 151 of the tacking mechanism which is here shown as being of a wellknown ty e. rlhe contact of the tacker nozzlc 151 with the work raises a vertically disposed trip latch 152 (Fig. 1) which is held in operative position by a spring 154 attached to the end ot an outwardly extending arm ot the latch and to the machine integree frame and moves the forward end 153 of a trip lever 155 pivoted at 156 to a lever 179 and causes a clutch operating lever 157 to move forward under the influence of a spring 159 and throw a continuously rotating pulley 161 into engagement with a cone clutch member 163 and thereby transmit motion to the shaft 165. On this shaft is placed a crank 167 which is provided with a cam roller 169 whichl operates in a cam groove 171 of a beam 173. The reciprocation of the beam 173, produced by the coaction of the cam roller 169 and the cam cove 171, effects reciprocation of a driver bar 175 to drive a tack into the rand and heel.- After one tack has been driven, a cam 177 on the shaft 165 operates lever 179 to throw the trip lever 155 forward and allow the latch portion 181 of said lever to engage a block 183 on the clutch operating lever 157. After this engagement has taken place, further action of the cam 177 moves lever 179 with trip lever 155 mounted thereon backward, thereby moving the clutch operating lever 157 backward to release the clutch 163 from the pulley 161 and disconnectthe tack driving shaft from its source of power. Still further backward movement of the clutch operating lever 157 operates to bring a brake member 185 carried by the lever 157 into engagement with the brake member 184; to check the rotation of the shaft 165 and prevent further operation of the tack driver. Successive vertical reciprocations of the work table will produce successive tack driving operations progressively to attach the rand to the heel.

rlhe cycle of operation that completes the attaching of the rand to one heel leaves the'v heels in a neutral position, in the machine, that is, the tacker nozzle is disposed in a plane between the heel breasts as shown in Fig. 2, and the contact nut 107 is in vertical alinement with an adjustable contact member 191 mounted on the lower end of a rod 193 which has a bearing in the machine frame. The next vertical reciprocation of the work effects an engagement of member 107 with member` 191 and raises the vertically disposed rod 193 and also a trip dog 194 attached theretowhich engages the outwardly extending arm of the latch 152 and removes the latch, against the tension of the spring 154, from under the end of the lever 153 thereby causing the tacking mechanism to be suspended during this cycle of operation. The upward movement of the rod 193 simultaneously operates mechanism to place a rand severing knife 197 in operative position and consists of a dog 196 attached to the rod 193 and having a vertically extending pin 199 which contacts with an ear 201 of a sleeve 203 pivoted on the rod 202., This sleeve is provided with a contact stud 205 which, when the sleeve is rocked about its pivot, contacts with the upper member 204tof a jointed lmife carrier 206 and places the upper portion of the carrier in vertical position in which position itis held by a spring 208 secured te the lmife carrier 206 at one end and having its other end secured to the member 204 at a point odset from its vertical axis. 1n this position of the knife carrier a lu 209 on the beam 173 contacts with an. adjustable screw 207 on the carrier to actuate the rand cutting knife simultaneously with the actuation of the driver 175 to drive the first nail in the succeeding heel. r1`he lu j 209 has a depression 210 therein which t e head of screw 207 may enter to secure a more stable connection between the beam 173 and the screw 207 and the contact stud 205 may be adjusted by a threaded portion 211 and a set nut 213. rThe knife 197 is connected to knife block 217 by means of bolts 219 and adjustment of the knife laterally is provided by means of a tongue 221 and a groove y223 in a block 225 at thebottom of the knife carrier 206. |The round shank of the block 225 is attached to a depending stem of the knife carrier 206 by the nut 226 to admit of a horizontal angular adjustment of the knife so that it may take the direction agreeable to the breast of the heel. The knife carrier is provided at the upper end of its lower member with a bifurcated portion 227 into which a tail piece 229 of the upper member 204e is fitted, and the two members of the jointed carrier are connected by a bolt 230. Byl reference to Fig. 8 it will be seen that when the upper member of the jointed carrier is in vertical position this tail portion 229 is, contained in the bifurcated portion of the lower section of the member 206, and it is then free to reciprocate vertically in walls 231provided in the frame. After the knife has operated to sever the rand, it is retracted from the work by a tension spring 233 upon the next upward movement of beam 173, this spring being connected with the arm by a stud 235 and to a. plate 237, see Fig. 1, which retains the carrier 206 within the walls 231. As 'the knife arm is retracted from the work a trip member 239 operating under the influence of a spring 241 connected with the plate 237 operates to throw the tail piece 229 backwardly and rotate the upper member 204 of the jointed carrier forwardly and out of operative relation to the reciprocating beam 173. The member 20d is held in this position by a spring 208.

Mechanism is also provided for automatically stopping the operation of the machine during this cycle of operation and this is eiected by providing upon the rod 193 a dog 195 which is actuated at the time the rod is reciprocated, to rock a bell crank lever 251 pivoted in thermachine frame, and by assises so doing release a lever 253, pivotally connected to the machine head in a block 255, from under a catch provided on one arm of the bell crank 251. At the rear end of the lever 253 vwhich is shown in dotted lines, Fig. l, connection is provided by means ot' a rod 257 with the Horton clutch 13 and upon releasing the bell crank lever 251 the lever 253 is allowed to rotate in its connection 255 by the weight of the rod 257. rllhe downward movement of rod 257 releases the clutch 13 and stops the machine at the end of that cycle of operation. A hand. pin 258 (Figs. 4 and 5) on the bell crank lever 251 makes it possible for the operator to rock the bell crank and thereby release the lever 253, without waiting for the contact oi the contact members 107 and 191. rlhe lever 253 and its connection with the machine head is shown in Fig. 5 which also shows the ordinary tack feeding mechanism which is operated by the cam 177, a bell crank lever 259, a bifurcated lever 261, a rock-shaft 263, and. a tack separating member 265 and its holder` 267. It should be noticed that the dogs 194, 195 and 196 are capable of adjustment on rod 193 and desirable adjustment of the timing of the mechanism operated thereby is facilitated.

v To stop the rotation of the heels in a predetermined or neutral position after the rand has been completely attached to the heel, mechanism is provided, shown in Fig. 3, which consists of a latch 271 arranged to engage a notched portion 273 in the clampinp,l plate 95 as the second heel is fed into position to be operated upon. The latch 271 is provided with a stud 275 to contact, upon the upward movement of the Work supporting frame which occurs when the hee s are in a neutral position in the machine with an inclined edge 277 of an adjustable latch trip attached to the machine head to retract the latch 271 from the notched portion 273 of theclamping plate 95. The latch may be adjusted by means of an adjusting screw 279 and a thumb nut 281 to vary the time at which the engagement of the latch 271 with the notch 273 takes place and thereby position the first tack driven into the heel at any desired distance from the edge of the heel breast. This adjustment is desirable to prevent the knife of the heel breasting machine from engaging the nail in the latter heel breastingo eration if driven too near the breast of t. 1e heel. The latch 271 is yieldingly maintained in forward position by means of a spring 293 and is positioned in the work supporting frame by a plate 295 held thereon by bolts 297.

The complete cycle of operations of this machine upon the work may be described as follows:

The clamping `frame 95 is Withdrawn from under the tacking mechanism by the handle and a heel placed between the pins 101 on the right hand side, Figs. 1 and 6, of the frame 95 and with its breast face against the side of the plate 103 upon which are mounted the rollers 113 to press the heel down upon the plate yieldingly. r1`he heel is clamped on the frame in a position to receive the first tack and when the frame is released by the latch 271 the side of the heel will be engaged by the pronged feed wheel 55. A strip of rand is passed through the rand guide 137 and the end ot this strip ol" rand is placed flush with the heel breast. The rand roller guide 129 may new be adjusted so that it will place the rand with its thicker edge slightly without the periphery oi. the heel. This insures that the later tri1n ming ot' the heel at a bevel will leave the edges ot' the heel and rand flush. l/Vhile the rand is in thisposition, the thick edge of the rand rests upon the heel and the thin edge oi the rand will be slightly above the heel. The operator starts the machine by depression of the foot treadle which, by mechanism already described, produces vertical reciprocation of the Work support while the pronged wheel 55 imparts to the heel a step-by-ste feeding motion, the vertical reciprocation an the step-by-step feeding motion of the work support being so timed that the heel is 'fed into tack receiving position during the downward movement of the work table and when the work support is at the height of its vertical reciprocation the pronged wheel 55 does not impart feeding motion to the heel. A t the height ci the reciprocation, thc contact of the rand strip and heel with the tacker nozzle 151 is produced and causes the first tack to be drivenl through the rand into the heel. rThis operation is repeated for each tack to be driven andthe distance between the tacks driven may be predetermined by the adjustment of the cam roll 47 toward or from the cam 39 as already described.

By the time the last tack is driven in the lirstheel the notched portion 273 on the oppsite side of the clamping,` member has been brought around toward the latch 271, and the feed of the heel occurring during the downward movement ot' the table to complete the cycle of operation which drove the last tack in the heel elects an engagement of the latch 271 with the notch 273 thereby stopping` the trame 95 in a neutral position with the contact members 107 and 191 in vertical alinement and limiting the position into which the succeeding blank may be fed by reason that further rotation ol pronged wheel 55 after this engagement produces simply a sliding' or rubbing contact against the heel. Up to this time one heel has been completely tacked, a second heel. has been inserted in the opposite side of the clamping frame by the operator during the tasking of the first heel and the trame 95 occupies a neutral position with respect to the tacker `nozzle andrand severing knife. The vertical reciprocation of the work support and heels in this position eects an engagement of the contact pieces 107 and 191 already described which raises the rod 193 and causes the dog 194 to tri the latch 152 and suspend the operation o the tack driving mechanism. The dog 196 also operates at this time to actuate the mechanism 'to straighten the rand severing knife and the dog' 195 to release the lever 253 and automatically stop the machine at the completion of this cycle of the machine. The latch 271 is also retracted from the notch 273 upon the upward portion of this reciprocation of the work support by an engagement between the stud 275 and the inclined edge 277 on the frame of the machine to allow the heels to be fed into a position for one to be operated upon by the severing knife and the succeeding blank to receive the first nail.

When the machine is restarted the contact of the tacker nozzle 151 with the work actuates the tacking mechanism to drive the first tack in the succeeding heel and by mechanism before described simultaneously operates the rand severing knife to sever the rand connecting the two heels. 1t will be noted that by the simultaneous action of the severing knife and the tacking mechanism to drive thev first tack in the heel, the rand supported between the heels will be properly supported for the action of the knife and that as the breast faces of the heels are only a distance apart corresponding to the thickness of the severing knife, the rand is severed substantially flush with the heel breasts.
