Application filed March 27, 1916. Serial No. 86,958.

To all whom it may concern.

Be it known that I, CHARLES -C.-i3nziin, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of li iassachusetts, have invented a .new and useful improvement in HeeLLastover-draw movement of the wipers and then to retract the wipers so as to expose the edge of the overdrawn upper sufiiciently to permit the insertion of fastenings therethrough. As well known to those skilled in the art this retraritive movement of the Wipers is highly objectionable.

An object ofthe present invention is to produce an end lasting machine in which the objectionable retractive movement of the wipers hereinbefore referred to is obviated.

To the accomplishment of this object and 'such others as may hereinafter appear, the features of the present invention contemplate the provision of certain devices, combinations and arrangements of parts fully set forth hereinafter, the advantages of whit-hwill be readily understood by those skilled in the art. j

The various. features of the present invention will be readily understood from an inspeetion of the accompanying drawings illustrating the best form of the invention at 'iresent known to the inventor, in which,

Referring to the drawings for a prelinnnary general description of the heel lasting machine the work is supported upon a horizontal table in position for the operation of wipers which are manipulated by the op erative to updraw and overdraw the upper at the heel seat. At the completion ofthe updraw movement of the wipers the back edges thereof are separated from the edge of the shoe bottom by a strip of overdrawn upper sothat the overdrawn upper maybe fastened without retracting the wlpers.

' The-strip of overdrawn upper is fastened by an automatic tacker which is fed during its tack-inserting movement to transfer the point of ppe'ration around the heel seat from one breast corner to the other at which oint the drivin mechanisms for drivin is b the tacks and feeding thetacker are automatically thrown out of operation.

- The machine illustrated in the drawings which a leader 5 ('Figs. 3 and 4) is atperforms the heel'lasting operation on a 'partially lasted shoe comprising an upper 1 (Figs. 1 and 2) the forepart of which is held in lasted positionagainst the edge of the'sole on the bottom of the last by a binder'2 secured in its binding position by a clamp 3 the jaws of which are. arranged to embrace the opposite sides of the shoe. The

upper at the shank and around the heel seat projects loosely about the shoe except at substantially the breast line' where a cord extending across the shoe, connects the free edges ofv the" upper." The partially lasted shoe is mounted on ajack d to tached between runners .6 depending from a frame extending" laterally from thejack.

During the operation of the machine the jack 4 is supported by a flat table 7 car-.

' slideway ic ng. a for aslide lliwhicli CZLIIIGS afplate 12. having'jaws arranged in a V to embrace the heel end ofthe leader. The plate12 is normally advanced toward the front end of the table 7 by a spring 18 coiled around a rod 141' secured-tothe slide 11v and interposed between the backof the 15 formed in the head 8. After-the heel end ofthe leader is properly engaged with the jaws in the platef12 the jack and plate 12 are pushed rearwardly until theleade-r- 5 slide 11 and the end of a spring chamber I engages a' fixed stop 16, .on the table 7,

'which loosely-passes through 1 hole 17. .80

formed in the slide 11.. The stop idetermines the operative position of the work with relation to the heel lasting tools. 3

.- To clampthe jack in operative position 0n the table the machinecarries a pair of 7 arms 18 (Figs. 1, 2,. 8 and dfarranged to embrace the runners .6 and also a plate 19 having jaws arranged in a V to embrace the T toe end of the leader.; The arms 18 are pivi oted on the head 8;.beneath the table 7 (Fig.

The lower ends ofthe 'arms118 are connected by links 20 to the upper end of a box 21. The. lower end of the box 21 is car-f ried bya rod 22 (Fig. 8) which is adjustably connected to the free end of an arm 28-proj ecting from airock shaft 24 journaled in the base-9. The rock shaft 24 is provided with a second arm 25 (Fig. 1) which is connected by a rod 26 to a treadle 27 mounted to move vertically on a pivot 28 and to move laterally about a pivot 29. With this construetion depression of the treadle vertically.

about its pivot 28 closes the arms 18 upon the runners 6. I clamping position the treadle is moved laterally about the pivot29 toposition the treadle beneath a locking lug 30 (Figs. 1, 2- .and 4) carried by the'base'9. l The plate 19 which embraces the toeienc .of the leader is carried upon a slide 81 (Fig. 8) mounted to slide in the slideway" 10.

'After the leader 5 is engaged with thestop 16 and before the arms 1.8 are engaged with To look thearms 18 in the runners 6 the plate 19is moved byhand I to embrace the toe end of'the lead-er. In order'to lock the plate 19 in engagement .1 l5 7 with the toe end of the leader when the arms a 18 are actuated to clamp the runners'G the slide 81 is provided with a depending arm is 82 which projects upwardly from a horizontal rod 88 mounted to slide freely in a lug 34L depending fromthe head 8.; The rod 88' is normally loosely embraced by a clamping in turn is pivoted to a. verticalarm 87 car-' ried by a rock shaft 88 journaled in a bracket89 on'the frame9-;The rockshaft arm. 85pivoted to .a horizontallink86'which 88 is provided with a secondarm d0 (Fig. ,1)

Vith this construction the rod 83 may befreely moved through the opening in the 'Which is connected tothe arm 25 .by'a link 7 clamping arm. to position the plate -19 when the treadle is disengaged from the between the arms of the yolze. -.The bearing 44 loosely carries a. cylindrical. block 46 formed on a yoke 47. The arms of the yoke 4'? extend in a direction substantially longitudinally of the shoe and terminate in a bridge 48 which forms a transverse arch over the shoe bottom. I I

The bridge 48 supports a wiper carrier 49 having wipers 5O suspended therefrom. To this end the wiper carrier 49 carries a pair of struts 51 (Fig. 10) which are universally connected at their upper ends to the wiper carrier and at their lower ends to the wipers 50. The wipers comprise a pair of sections jointed at 52 (Figs. 8, 9 and 10) and each section carries a narrow spring metal finger 53 which constitutes the active faces of the wipers. In the axis of the pivot 52 the wipers are universally connected to a third strut 54 (Figs. 5 6 and 7) theupper end of which is loosely mounted in a chain ber 55 formed in the wiper carrier 49.

In order to gage the initial operative position of the wipers with relation to the'shoe bot-tom'the bridge 49 carries a gage 55 (Figs. 5, 6' and 7). The soleengaging foot of the gage 55 is swiveled on the lower end of a post 56 which is adjustable vertically in an L-shaped carrier 57 pivoted centrally at 58 on the bridge 48. The gage 55 is normally held in central position by a leaf spring 59 secured to the bridge 48 and arrange engage the square end of'the gage carrier 57. The gage 55 engages the shoe bottom "under the influence of a. pressure mechanism. To

this end the bearing 44 is pivoted to a cylindricalsleeve 60 which slides over acyhndrical arm 61 plvoted at 62 between the 'air ns'of a yoke 63. The yoke 63 is carried by a rock shaft 64 journaled in the head 8.

interposed between the bottoms of the sleeve 60 and arm 61 is a spring 65 which is coiled around arod 6G loosely passing through the sleeve 60 and arm 61 and held in place by nuts .6? on the'lopposite ends of the rod. *With this construction the sleeve 60 and arms 61 and53 form a toggle one of the yield longihandles 72 connected to the wipers.

shoe bottom and apply the pressure mechanism thereto simultaneously with the clamp- 1ng of the. arms 18-and plate 19 therock shaft 64 is provided with an arm 68 (Fig. 1)

which is connected to the treadle 27 by a rod 69. With this construction actuation ofthe ,treadle 27- tends to straighten the arms of the pressure toggle thus tipping the bridge 48 downwardly about the pivot 45 and thereby placing the gage 55 upon the shoe bottom. Continued pressure on the treadle 27 causes the spring 65 to be compressed thus applying pressure to the gage 55. As it-is desirable that the gage 55 will always become elevated from the shoe bottom when the treadle 27 is released, the base 9 carries a stop 70 (Fig. '1.) which engages the arm 68 during the depressing of the treadle 27 and prevents the complete making of the pressure toggle. When the. treaclle 27 is released a spring 71 (Fig. connected at one end to the pivot 62 and at the other end to the standing upper just below the exposed face of the shoe bottom when the Wipers are closed upon the shoe by manipulation of the This position is illustrated in Fig.5. 1. fter the fingers are initially engaged with the upper in the manner described further actuation of the handles causes the fingers 53 to slide up the back of the shoe against the pressure of the spring-65 thus imparting an updraw movement to the upper and stretching it around the face of the heel. -The gage 55 is elevated from the shoe bottom during this updraw movement of the wipers thus causing the pressure of the compressed spring 65 to be transmitted through the wipers to the upper engaged by the fingers 53. Con- ,tinued closing movement of the handles-72 causes the wipersto wipe the updrawn upper over upon the shoe bottom.

By mounting the wipers in the manner described they rock longitudinally in the seat. The pivot 52 and struts 51 are mounted so that their projections upon the plane of the shoe bottom coincide with the shoe bottom between the ends thereof. Consebearing 44 to adapt themselves to the plane quently at the completion. of the wiping stroke of the wipers the back or inactive edges of the wipers are separated from the' edge of the shoe bottom by a strip of overdrawn upper.

This construction permits 7 the fastening of the overdrawn upper to the heelsea t without the objectionable retracting movement of the wipers featured in end lastingmachines of the prior art.

- In order to secure the upper to the heel seat the machineis provided with atraveling tacker which automatically inserts tacks,

in the stripiof overdrawn upper separating "the back edges of the wipers from the edge of the shoe bottom around the heel seat from one breast corner to the other. The tacks are driven into the shoe by a driver 73 (Figs. 17 and 19) which operates through a, throat 74 formed in a nozzle 75 supported from a head 76. The driver 73 is securedby ascre'w 77 to a slide 78 which is weighted by alweight 79. Theslide 78 reciprocates in ways 80 formed in the head76. i a To operate the driver the slide 78 is'connected by a linkc82 to the free end of a spring metal arm 83 the other endof which is secured-to an arm 84 pivotedonahorizontal stud 85 secured to the head76.- The driver. 7 3is-a'ctuated to drive the tack by a spring 86 which is coiled about. a'grod87 pivoted on the head 76 and loosely passed through a horizontal stud 87 on the arm 84.

The spring 86 is interposed between the top of the stud 87 anda washer 88, on the rod, backed up by suitable adjusting and locking nuts 89. To compress the spring 86 for the drivingstroke of the driver the arm 84 carries a shouldered stud '90 which is embraced by a slotted connecting rod 91 pivoted at 92011 a crank arm 93. The crank arm 93 is loosely'pivoted on a horizontal shaft .94journaled in the head 76; The crank arm 93 is rotated in the direction of the arrow, Fig. 17 ,toelevate the arm 84 and thus compress the, spring 86 by a pin 95 carried by a disk 96, on the shaft 94, and arranged to engage the crank arm 93. The

pin 95 carries the crank arm 93 and the jectout of the nozzle (Fig. 19) under the influence of the momentum of the weighted slide 78, thus insuring the drivingv of the tack by a whipping stroke. To prevent the compressed spring 86 from rotating .the

af 94 in a reverse direction when the ma-J' chine is stopped with the spring 86'under compressiom'the right side of the head 76 carries 'a ball clutch-97 '(Fig. 18) arranged to engage the peripheral edge of a. disk 98 97 permits the shaft to rotate in the direction of the arrow Fig. '17 but clutches thedisk 98. when a tendency arises to rotate the shaft 94 in the reverse direction.

Theshaft 106 is provided with a bevel gear which meshes with a-siniilar gear 109 loosely mounted on a vertical shaft 110 passing loosely threugn a V three-armed bearing 111 supported from the slide 107. Thebevel gear 109 is provided with clutch'teeth 112adapted'to be engaged by clutch teeth-formed on 'a clutch sleeve 13 splined onthe'shaft 110. The shaft 110 is driven continuously through worm gearing during the operation ofthe machine from a horizontal, shaft 114 (Fig. 2) 'driven by an electric motor 115 mounted on an extension ofthe base'9. 4 J1 1 7% f.

The tacks for fastening the overdrawn upper arecarried in aninolined raceway 116 (Figs. 11, 12, 13, and 14) composed of apair of spaced plates to form a roadway secured to the head 76and having extensions 117 (Fig; 12) thereon bolted to the nozzle 75.

The roadway forthe tacks between the'plates is covered by a cover 117 which isspaced above the plates to permit a freepassagefor theheads of the tacks. To hold thetacks in the raceway the head of the lowermost tack is engagedby a gate'118 (Figs. 12, 13 and 17). which is pivoted on the head 76 andnormallyheld in tack-engaging position by a pin 119 (Fig. 17) engaged with a fin 120 formed on the back of the gate. The tacks are withdrawn one ata time from the raceway 116 and passed through an opening 121 (Fig. 17 in the throat 74 down which'they fall until stopped by a pair of leafsprings 122 (Fig. 19), carried bythe nozzle 75,

which straighten the tacks to insure their proper engagement by the end of the driver. In order to properly handle a tack from the time it leaves the raceway funtil-it ,is dei I livered to the throat 74 the nozzle 75 is ex- .125 tended rearwardly to-form a vertical ledg'e 1 123 (Figs. 12 and 13) arranged beneath the end of the raceway 116and in the vertical plane thereof. The space between the' bottomof the raceway and the upper surface of the ledge 123 is so small that but one tack at n'fall from the raceway upon the men the te periodically lifted th operation of the machine. Mounted to straddle the stationary ledge 123 is a picker1'24 (Figs; 12, 13 and 14) which reciprocates on the top edge 125 of the nozzle 7 5 betwee the plates 117. The picker 124 is provided witha slot 127 15) which extends from the front end of the picker to a pointnear its rear end. Centrally located on the picker 124 is ashoulder 128 (Figs. 12 13 and shaped to engage beneath the head of a tack. When the gate 118 is elevated the lowermost tack in the raceway falls upon the picker 124 at the rear of the shoulder 128. The head of the tack rests uponthe top of the picker and the shank of the tack passes through the slot 127 and rests upon the top of the ledge 123. Then the picker is moved rearwardly. The tack on the top of the picker is prevented from moving rearwardly with the picker owing to the limited space between the top of the picker and the end of the raceway. Continued rearward movement 01 .the picker positions the head of the tack in the shoulder 128 whereupon the picker is moved forwardly. During the forward movement of the picker the shank of the tack drags over the ledge until it is withdrawn therefrom and then the tack swings downwardly under the influence of gravity untilthe tack rests upon the top of the picker in front of the shoulder 128. At this time transferring device 129 (Figs. 12, 13 and 14) sweeps through the slot 127 and pushes the head of the tack through a guideway 130 (Fig. 15) formed between two plates 131 carried by the picker 124 and into the throat 74. As shown in Fig. 12 the transferring device 129 closes the opening 121 in the throat 74 at the end of the transferring movement in order to obviate all danger of the point of the tack striking the floor of the opening 121 and thus become tipped across the throat and jammed therein upon the descent of the driver. 1

In order to elevate the gate 118 to release the end tack the gate carries a pin 132 (Figs. 12. 13 and 14) which is embraced by a slot 133 formed in one end of a link 134 pivoted to a post 135 projecting laterally from a lever 13" pivoted at 137 to the head 76. The upper end of the lever 1 6 is connected to one end of a link 138 the other end of which: is provided with a roll (not shown) engaged with a can]. groove-139 (Fig. 18) formed in the inside face of the disk 98. v

The picker .124 is reciprocated, in the manner described to pick the tack from the ledge 123 and position the tack for the operation of the transferring device 129, by the same lever. 136 that operates the gate 118. To this end the lower. end of the lever 136 is provided with a laterally extending end of the forward stroke of the picker, the. difference in timing being permitted by the slot 133.

The transferring device 129 depends from a lateral extension 141 (Fig. 15) of an arm 142 (Figs. 12, 13 and 14) which depends from a sleeve 143 pivoted on a horizontal stud 144 on the head 76. A second arm 145 on the sleeve 143 carries ablock 146 (Fig. 11) which is connected to a link 147 by a yielding connection to permit the transferring device to yield if a tack becomes jammed in the slot 121, and thus prevent breakage. To this end a rod 148 (Fig. 11) connected to the block 146 passes loosely through an extension 149 on the link 147. Coiled around the rod 148 is a spring 150 interposed between the extension 149 and suitable adjusting and locking nuts 151 on the rod. The other end of the link 147 is slotted (Fig. 14) to embrace the shaft 94 and is provided with a roll 152 engaged with a cam groove 153 in the outside face of the disk 98.

The tacker is'arranged to operate in th position. shown in Fig. 1, hereinafter called the fastening-inserting station, to drive tacks in the strip of overdrawn upper exposed on the shoe bottom between the back edges of the wipers and the edge of the shoe bottom. While the tacker is driving tacks it is continuously moved around the heel seat of the shoe from one breast corner to carried by a second flat plate 156. The plate 156 is" pivoted. near its front end upon a pin 157 carried by a slide 158 mounted to em brace and slide upon ways 159 (Fig. 24) formed in a horizontal extension 160 of the vertical slide 107. The plate 156 carries a spring chamber 161 (Fig.20) in which is mounted a rod 162 which passes through the chamber 161 below the tacker head 76 (Fig. 26). liiounted on the rod 162 is a pair of sleeves (Fig. 20) having heads 164 (Fig. 26) arranged to engage the tacker head 7 6L Coiled around. each of the sleeves 163 is a spring'165 (Fig. 20) which is interposed between the head 164 and a Washer 166, on

The disk 174 is mountednear the upper end of a vertical shaft 178 (Fig. 26) journaled in the extension 160. The lower end ofthe shaft 178 isfprovided with a worm wheel 179 which is driven by a worm 180 (Fig. 25) formed on a shaft 181. The

shaft 181 is provided at its rear end with v a bevel gear 182 (Fig. 22) which meshes with a pair of bevel gears 183 loosely journaled on the shaft 110 and bearing 111. Interposed between thefbevel gears 183 is a having clutch teeth arranged to alternately engage similar teethyformed on the'bevel gears;183.

The rockshaft-187 is provided with a depending arm 188 which isconnected to a sliding link 1'89 (Figs. 1 and 21) mounted to slide in an arm 190 secured to the extension 160. .The link 189 is shifted in the arm 190 by a handle 191 which is secured to afpla'te 192 pivoted at 193 on the extension160 and having a limited amount of play between lugs 194 and in one direction to transfer the nozzle from 7 195 (Fig. 21) in the link 189. V The link 189 v is normally held in neutral position with "the clutch sleeve 184disengaged from'both of the bevel gears 183 by a spring latch 196,

on the arm 190, which is arranged toengage the center one of the three notches 197 formed nearthe free end of the link 189.-

Then the nozzle 75' is at the breast corner seat to a corner B the handle 191 is pulled toward the operative thus causing the link 189 to slide forwardly to clutch the upper bevel gear 183*to the shaft 110. The clutch is held in by the latch 196 which rides out of the central notch 197 during the forward movement of the link and into the rear notch 197. When the nozzle 75 is to be moved from the breast corner B to the breast corner A the handle 191 is pushed away from the operative thus clutchingthe lower bevel gear 183 to the shaft 110 and causing the latch to ride into the front notch 197.

In order to simultaneously throw in the drive for the tack inserting mechanism when the clutch sleeve 186 is moved in either di rection the clutchsleeve 113 is engaged by a yoke 198 (Fig. 21) projectingflfrom a rock shaft 199 (Fig. 22) by a toggle 201 one arm of which is linked to the arm 200 and the other arm of which is secured to the rock shaft 187. When the clutch sleeve 186 is in neutral position the toggle 201 is straightened as shown in'Fig. 22. When the clutch sleeve 186 is: shifted in either direetion to start the mechanism for feeding the tacker the toggle is broken thus 'sliding the r clutch sleeve 113 into engagement with the bevel. gear 109 and thereby starting the driving for the tack inserting mechanism.

' In order to automatically stop the tacker when it reaches the'breast' corner Bthe plate v192 is provided with an incline 202 arranged tacker' is automatically stopped when it reaches the breast corner A by a second incline 205 on the plate 192 which is engaged bythe stop 203 to tip the plate 192 on its pivot and thus slide the link forwardly to bring the clutch sleeve 18 1-into neutral position. As the lengths of the heel seats vary in different sizes of shoes it is desirable to vary the stopping position or the tack in accordance with the variations in the length of heel seat operated upon. To this end the pin 203 is carried by a block 206which is mounted for adjustment along aslot 207 formed in the plate-20a. The block 206 is adjusted in the slot 207 to vary the stopping point on shoes of difierent sizes by a screw 208, threaded into the block 206, mounted on the plate 204. v

When the nozzle 75 is located at the breast corner A the. head 76 may be moved from the fastening-inserting station to a fastening-storage station in which station the raceway 116 is alined with a raceway 209 in order that the supply of tacks in the raceway 11.6 may be replenished. To this end the slide 107 (Fig. 25) is mounted toslide in ways 210 formed in the column 108. The weight'o'l the slide and its associatedparts is counterbalanced by a weight 211 (Figs. 1 and 2) which is connected to the slide 107 by ropes 212 (Fig. 25) passing over pulleys 113 (Fig. 28) on the column 108. To move the slide 107 to position the tacker at the fastening-inserting station or at the fasten ing-storage station the slide 107 is connected to a link 214 (Fig. 1) the lower end of which is connected to an arm 215 projecting from a rock shaft 216 journaled in the base 9. A second arm 217 projecting from the rock shaft 216 is provided with a handle 218 in convenient position for manipulation by the operative. I

.The raceway v209 is loosely received between a' pair of vertical plates 219 rising from an extension 220 of the column 108. The raceway 209 is yieldingly held between the plates 219 by aleaf spring 221 one end of which is secured to the raceway 209 and the side of which is pressed upon by the ends of a pair of screws 222 secured to one of the plates 219. The raceway 209 supports the heads of the tacks which are covered by a cover 223 spaced from the raceway. The tacks in the storage raceway 209 are held therein by a gate 224 which is pivoted at 225 on one or the plates 219. The gate 22a'is normally held in tack-engaging position by a l af spring 226, on the back of the gate, which is engaged by a pin 227 on one of the plates 219. The shanks of the tacks depending through the roadway near the end of the raceway 209 are alined with the roadway by a pair of wedgeeshaped blocks 228 (Fig. v32) which are supported at the lower ends of leaf springs 229 supported at their upper ends by a bridge 230 secured to the raceway 209. Vfhen the raceway 116 is elevated intothe fasteningstorage station a raceway 209 the gate 22 1and blocks 228 return to their initial positions under the in fluence of the

springs

226 and 229, respectively, in readiness to act upon a new lot of tacks presented for storage to the raceway 209.

The raceway 116 is in line with the storage raceway 209 only when the-nozzle at the fastening-inserting station {is located at the breast corner A (Figs. 20 and 21). As'thebreast' cornerA will varywith different shoes it is desirable to provide some means for positively limiting the elevated position of the raceway 116 so that it will always be in line with the raceway 209 whether the shoe last operated upon is large To thls end the slide 158 carries or. small. an arm 233 (F ig. 20) which is provided at its free" endwith a block 23 1 22) having an inclined face 235 arranged to-cooperate with aninclined face on a block 237 carried by the column 108. The inclines of the

faces

235 and 236 are parallel to the incline of the

raceways

116 and 209 so that the

raceways

116 and 209 will always aline whenthe raceway 116 is moved into the fastening-storage station notwithstanding variations in the stopping position of the nozzle 75 at the breast corner A for different sizes of shoes.

In order to provide means for automatically bringing the starting and stopping link 189 into neutral position when the tacker head is elevated, during its opera-' tion, to withdraw it from the fasteninginserting station the column108 carries a rib 238 having a V-shaped end which enters between a pair of blocks 239 on the link 189. It the driving mechanism for the tacker .is stopped when the tacker head is elevated the rib 238 enters betweenthe two blocks 239 and prevents the starting of the driving mechanisms for the tacker while it is moving toward or from the storage station. It the driving mechanisms for the taclzer are in operation when the tacker head is elevated the lower end of the rib 238 wedges itselt between the blocks 239 and shifts the link 189 into neutral position from either its advanced or its retracted position.

In order to provide the storage raceway 209 with tacks the column 108 supports a hopper 2 10 which is loosely mountedon one end of a stationary rod 241 secured to the plates 2l9-sothat it may be. tipped back to clumnj 108, A gear 242, securedto the hopper 240 and loosely mounted on, the rod 241, meshes with a pinion 243 on a shaft 244;,journaled in: the column108 and driven from the vertical shaft '110 "by'b'evel gears .245 and 246 onthe shaftsllO and24A3 respectively. The hopper 240 is thus continuously rotated during the operation of the' machine' to tumble amass of tacks in the bottom thereof. The mass of tacksis insorted into the hopper 2 40 through a filling funnel 247 whichis pivoted on one 'ofthe expose an opening 248 in the front face of the hopper for the purpose of inspection or repair. Theinterior of the hopper 2&0 is

. provided with a pair'of buckets 249 each of which carries a pair of rails 250 spaced to provide a tack slot- 25l therebetween.

The buckets 24:9 are provided with sloping walls 252 in order to direct the points of the tacks caught by the buckets into the slot} 251. With this construction the buckets 249 are alternately passed throughthe mass of tumbled tacks in thehopper. shanks of the tacks will be deflected by the sloping walls 252 into the slot 251. Thereafter the heads of the tacks will assemble on the rails 250'until during the rotation of the hopper the ends of the rails register with acurved stationary raceway 253 carried by the'rod 241. Then the tacks. as-

' sembled ontherails 250-slidejtherefrom and into the raceway 253. The lower endof the raceway 253 and the upper end of the V raceway 209 are separated'by a gap 254 the point of registration with the raceway 253vhas been passed; to dump all the tacks remainingon the rails into the hopper To wedge them back into a position in which they will properly support theheads of the tacks the support for the raceway 253 is provided with a curvedway 1255 .(Figi 29) having sloping wallsat its entrancef The Y distended'rails 250 engage the slopingwalls Y and arewedged thereby back into the dotted line position:(Fig. 33). The way 255 then holds therails 250 with the properspace between them until the pointof registrationwith the raceway 253 is passed when the rails 250 pass out of the way 255 and spread apart to dump any tack still held on the Some of the.

253 spill rails. -The entrance. to the way 255. is

guarded by a. pair of spring metal flaring wings 25;? which prevent a tack from jamming'between'the entrance to the way 255 and the-rails 250. l r Y In order to provide afriction drive for the hopper 2l0 and thus prevent breal'rage in case a tack becomes jammed thereinthe shaft24c l is made: in two parts (Fig. 28) each part Betweenthe 7 75 construction being such that the disk 259 g having a collar 258 thereon. collars 258 a leather disk 259 is pinched the permitsthe left hand collar 258"(Fig. .28)

the rotation of the :hopper.

a It is found that the heel seats of some shoes slope upwardly from the breast line to slip.thereover whena jammed tack stops toward the back of the shoe while in others theheelseats slope upwardly from the back of the shoe toward the breast line. In order to maintain the nozzle 7 5 at a uniform distance. above the work notwithstanding these variations intheslope of the heel seats the machine of the drawings is'provided with a cam-260 (Fig. 1) comprisingva flat plate, loosely mounted on the top of I the bridge 48. The cam 2601is pivoted 'on a pair of vertical rods 261 mounted to slide through the bridge JCS-.3 The lower ends of the rods 261 carry a horizontal bar 262 extending transversely of the shoe; The cam 260 is engaged by a horizontal gage rod 263which is supported between a pair of arms 264:36- cured to the slide 158. In its normal positionupon the top of the bridge 48 the cam 260; is inclined to maintain the nozzle 7 5 through the height gage 263, at a uniform height above the heel seat of a "shoe which slopes upwardly from the breast line to the back of' the' shoe; When the heel seat'of a shoe operated upon'is in a horizontal plane wipers, as they'move over the shoe bottom dur ng the wiping movement of the wipers engage beneaththe bar 262 and elevate the 1 or slopes upwardly from the back of the V shoe to the heel-seat'the handles 72, of the pivoted end of the cam 260 and thereby inclin'e the cam 260 on the top of the bridge 48 to position the surface engaged by. the w the wipers. 1 In its'normal idle position the ta'ekerhead 7 G is at the fastening-storage station with the

raceways

116 and 209 engaged to permit gage 263 parallel to the heel seat engagedby tacks to flow from the raceway 209 into the raceway 116. I The electric motor is now thrownin to rotate the'hopper24r0 to supply the'raceway, 209 with tacks.v When a partially lasted shoe is jacked on a leader and positioned upon the table 7 between the

gage plates

12 and 19 the treadle 27 is depressedto lock the leader upon the table, to

engage the gage 55 with the heel seat of the sole, and to apply the pressure .mechanism to the gage 55. The'treadle 27 is then moved laterally beneath the locking lug 30 to lock the parts controlled therefrom in their 'op-' erative positions. The handles '72 are then grasped by the operative and manipulated to cause the wipers to initially engage the shoe. As shown in Fig. 5 in this initial position the wipers engage the upper just below-the exposed face of the sole on the bottom of the last- Further closing movement of the handles '72- causes the Wipers to slide upwardly over the face of theheel thus stretching the upper thereon or, stated in another way, imparting an updrawniovement to the" upper. During the upward movement of the wipers the gage 55 israiSed from the solethuscausing the entire pressure of the'pressure mechanism to be trans mitted to the vork through the wipers Fig. 6). Continued closing movement of the handles 72 causes the wipers to wipe the updrawn. u )per over the bottom of the heel seat (Fig. 7), During the closing movement of the handles 72 the cam 260 is ad justed to conform to the longitudinal slope on the heel seat.

The handle 218 (Fig. 1) is now elevated to withdraw the tacker head 76 from the fastening-storage station and to position the nozzle '75 at the breast corner A on the heel seat. The handle 191 (Fig. 21) is then pulled toward the operative to throw' in the driving mechanisms for driving the tacks and for feeding the tacker. -The nozzle 7 5 18 now drlven around the wipers; During this traveling movement of the nozzle 75 the tacks are inserted in the heel seat to secure from the arms Band to return the wipers" to their original inoperative position. An-

other shoe is then positioned on the table 7' and heel lasted. When the nozs-zle 75 is engaged with the work and the driving mechanisms therefor thrown into 'operationthe traveling tanker will insert tacks from the breast corner Btolthe breast corner A at which point the driving mechanisms will be automatically thrown out through the engagement of the pin 203 with the incline 205. \Vhen the nozzle 75 is again elevated to clear the wipers advantage may be taken of its alinement with theraceway 209 to return the raceway 116 to the fastening-stole age station'and thus replenish the raceway 116 with tacks.

The nozzle 75 may be fed by hand, when the driving mechanism therefor is thrown out of operation, through a handle 265 (Fig. 1) on the endof the shaft 181.
