Application filed March 1, 1920. Serial No. 362,358.

To all whom it may concern.

Be it known that I, ERASTUS E. l/VINKLEY, a citizen of theIUnited States, residing at in the county of Essex and State of Massachusetts, have invent-ed certain new and useful Improvementsin Heel-Building Machines; and I do hereby declare the following to be a full, clear, and exact description. of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

wThis invention. relates to heel building machines, and it has special reference to 1 such machines as are adapted to successively assemble, aline, press and nail ponent lifts ofa heel. i In applicants- Letters Patent of the the com- United States No. 1,502,082, granted July; 22, 1924:, on an application, Serial No. 283,-

693, filed March 20, 1919, there is disclosed a heel building machine of the general character above mentioned which comprises a heel assembling mechanism and 'a' heel alining, pressing and nailing mechanismfwhich are so interconnected that they are operated as. a single unit, In this prior machine the successively assembled heels are delivered upona' receiving device from which they are taken by the operator and manually transferred and placed into alining, pressing and nailing mechanism.

. One of the objects of the present inven tion is to improve the construction andoper ation of the machine of the above mentioned patent; and to provide a machine of this general type which shall be compact in ar+ rangement, rugged and durable in construetion, speedy and reliable in operation; and which shall be particularly adapted for full automatic operation whereby the services of the operator may be dispensed with except in so far as the replenishment of the magazines with lifts is concerned.

' To this end, one feature-of the invention resides in the use of a heel assembling mec'lr anism similar to that of the prior patent above referred to, ponent lifts of a heel into one of a plurality of lift-receiving devices that are carriedby a rotatable turret and rotated in stepsthrough a plurality of operating stations, at which different operations upon the heels are concurrently performed. At

one of the stations, which may be considered piles are alined,

which delivers the com-.

the third station, the'heel-piles are presented for the inspection of the-op t lia i the fourth station the lifts form-ingrtherhe' L HEEL-BUILDING MACHINE; o I f ffj' pressed and nailed -after i which the heels are discharged upon a suit able conveyer which may be utilized to trans; fer them 'to'another or other machines for performing subsequent operations thereon.

' Another object of the inventionis to make provision for automatically" arresting the operation of the machine in the event that the assembling mechanism fails to deliver to the receiving devices one or-more' of the predetermined of the heels, vided for the operator to supply 'the miss-- ing lifts and thereby obv'iatethe possibility of building heels of improper height/J With this object in view, one ofthe fea turesof the invention 'resides inthe, use of an automatic measuring apparatus for determini-ngthe height of the loosely. assembled lifts delivered to the receiving devices and for automatically disconnecting th'eflmachine from the source ofjpower byl th row-j ing out its main clutch in the event-that any of the lifts are missing. l E I Afurther object of the invention' 'is to provide a simple, eifective and reliable alin-v ing device for insuring an accurate alinement of the breast edges and, the lateral edges of the component lifts of a heel.-

The attainment of this end is accomplished through the agency of a feature of;

the invention which contemplates thecof number of component liftsf whereby an opportunity is prois provided'with resilientlyvsupported side engaging alining members of a contour}; I CQIIGSPOI1C1111% to that of the ultimate eel and these members"fuifc slope" of the 7 tion during theadvancing movement of the device to engage the lateral edges of the lifts andby a wiping movementto force them tinto'properposition. In conjunction with these resiliently supported side-alining members, the alining deviceis provided with other rigid alining instrumentalities having the'curvature'and' the pitch of the ultimate heel and which cooperate with the rounded rear edges of the lifts to positively force them into position and effect an accurate alinement of the breast edges thereof against theabreast gage. After the heels have been thus alined and.subsequentlynailed,the alinmg; device is. withdrawn, during, which movementgit. removes the heel from the liftreceiving deviceand deposits it uponqthe conveyer already mentioned.

nother ob ect of the invention, having relation tothe nail driving mechanism, is to rovide automatic means for preventing the rivi1ig,of..a nail in the event that a heel is absent upon the lift-receiving device at the nailing station.

in nails into position to be driven.

, This-object isatta-ined by means of; a feature, of the invention which embodiesthe usual naillblock for receiving and deliver- This nail block. is: spring actuated into deliver.- ing position and is; normally restrained in it sfloading position. Heel detecting mechanism is. employed for. determining whether or. not, aheel is in position to be nailed and liver nails successively and singly to the nail-driving mechanism.

Accordingly, another feature of the in vention contemplates a nail-supply block of the Pope type having a series of rows of perforations for containing a. supply of nails, which block is: automatically actuated in steps in one direction to. present the successiverows in position above and m ahnement, with. the upper end of a single flexible,

nail tube. of the usual form. The upper end of. thesingle nail tube is actuated in a series off steps beneath the perforations in each row, whereby the nails contained therein are successively dropped into the tube. and delivered into operative position to be driven. Afterall the nails in any row of perforations, are delivered, the nail-supply locksisadvanced one step tov properly po siti on .t-he.,.next.row ofv perforations for. the

successive delivery of the nails contained therein. 7,

'The supporting frame 1.20 comprises a pair of pedestals 156 and 158 (Figs. 2, 3, 4,

6 and 7) which are attached to a bedplate 159 and which support and are rigidly connected by an upper frame member 160,

the upper end of whichcarries a bracket 162 upon which the. nailfeeding mechanism is mounted. 'The rotatable turret. is supported upon a plurality of centers or pivots 166 and 168 (Figs 2 and 7).;the former bein? mounted in a bracket 170 secured to the bed-plate 159 of theframe. and the latter being carried by a depending bracket 1? 2 that'is secured to the frame of the lift assembling mechanism 20 v The drive shaft 122. of the mechanism 22 is iournaled at one end in the side pedestal 174 (Fig. 1) of the assembling mechanism 20.and at theo-ther end is rotatably mounted in a bearing 176 (Figs. 5 and 6) forming part of the pedestal 158. This shaft 122 is mechanically connected to be driven from the cam shaft 44 of the assembling mechanism .20 by means of cooperating gears 17 81 180 and 182 (Figs. 5 and 17) and is provided at its opposite end with a mitre gear 184 which cooperates with a similar gear 186 for the purpose of driving the cam shaft 124- A plurality of cams 190, 192, 194. 196 and 198 (Figs. 6 and 7) are fixed to the cam shaft 124 and serve in conjunction with other elements to effect the proper timed-cooperation. of the various operating mechanisms of the machine.

As already stated, the turret embodies.

a plurality of'lift-receiving devices 128 ,.and

these devices are spaced degrees from each otherso as to be brought into the various operating stations atzeachrquarterirotation of the turret by the Geneva motion: i

just referred to; The lift-receiving devices 128 are of like construction and mode of 1 description of only one of said devices will be given Referring particularly to Figs. 2,5 and 7, each receiving device; comprises a bottom;

plate 222which is pivotally mounted upon a pin 224 and which is adjustablein' position about said. pin to accommodate the wedge or taper of the particular style of heels being built' The adjustment is effected by means of a set screw 226 which is carried bya supporting member 228 which also carries the pivot pm 224. Normally the bottom plate 222 is held down in engagement with said,

screw 226 by means of a spring 230 Coop} crating with the bottom plate 222 is anjup} 1 wardly extending plate 232 which 'constil tutes a breast gage to engage the breast ledges of the component lifts of the heel-pile. The

breast gage 232 is also" pivotally mounted upon the pin 224- arid isa djustable in posi-.

tion bymeans .of a set screw 234 to accommodate any desiredslope of the heel breast.

By properly adjusting the relative positions of the bottom plate 222 and breast gage 232,

the receiving device may .be adapted to re-i' ceive heels of any desired characteristics.

The supporting member 228 upon which the receiving device is mounted-is provided with a downwardly extending and vertically slotted portion 236 which is adjustably secured to one side of a vertically disposed carrier arm 238 by .means of screws 240.

By this adjustment, the receiving devices 128 maybe setor adjusted to aheight dependentupon the heightof theheels to be built. The carrier arm 238 is cruciform in section and is mounted forpa'ralleli vertical motion at the outer ends of a plurality of pairs of links 242 1 and 244,;the inner ends of which arepivotally supportedupon pins 246 and .248, respectively, said pins being carried by the central shaftQ126 :of the turret vIn'order to normally urge the rec'eiv v ing device to its ppe ost pcsiticn' and t permit it to be depressed as the lifts are progressively delivered thereto, a pri g" 250" For this purpose, each of the carrier arms 238 is provided with a radial projection 256 carrying a pivoted-roll 258. The depression of the various lift-receiving devices 128 priorto each stepping movement of the t-urrot is effected by means of the ring 130 which is provided with a hub 260 (Figs. 2 and 5) by which it ismounted for pivotal movement upon a supporting rod 262 extending horizontally across thefront of .the

.turret mechanism and mounted in the pedestals '156 and 174C. 'This ring is of such diameter that on being swung downwardly about its pivotal support, it is brought into engagement with the rolls 258 of the several carrier arms 4238, whereby said arms and associated lift-receiving devices 128 may be concurrently depressed in position. In this position the ring, and consequently the lift-receiving devices, is held duringthe rotational step while the ring serves as a circular track which is traversed by the respective rolls 258' The'actuation of the ring 130 is produced by means of a connecting rod 264; (Fig. 4), the upper end of which is pivotally connected to the side of the ring by a screw 266 and the lower .end of which has a pivotal connection to one end of a bell crank lever 268 which is mounted for pivotal movement upon avstud 270. The lever 268 is provided with an upwardly extending arm carrying a roll 274 which cooperatively engages with a cam 276, the latter being carried by and fixed to the drive shaft 122. The roll 274 is maintained incoopera'tive engagement with the cam-by the action of the various springs 250, and the cam is so designed as to periodically lower the ring 130 to'e ffeot the depression of the respective ping'movement ofthe turret, after which the ring is raised in position to disengage the several rolls 258 and to permit the springs 250-to elevate the lift receiving devices to their: operative positions.

During-the operation of the machine, the

turret is intermittently rotated to advance.

the several lift-receiving devices 128 through a plurality of successive operating stations, namely sa base-lift supplying station, an assembling station, an inspection station and a station at which theheel piles are alined, pressed,nailedand ejected. or purposes of explanation, the base-lift supplying station maybe considered the initial station of the machine, adj acent which the base-lift magazine 131 is located. This magazine comprises an upright member 278 (Figs. 3, a and 5) which constitutes part of a bracket 280 that is; secured to the .The lowermost lifts of the stack are su ccessively removed therefrom and advanced into position upon the bottom member-222 of each lift-receiving device 128, as it becupies the first station, by means of the pusher member 132 which is periodically reciprocated and adapted to engage the edge of the lowermostlift, advance it overthe supporting member 282, and deliver it to the receiving device. The lift being transferred is held under control during the transferring move nent by means of a resilient guide finger 294 which engages the top surface of the lift. The pusher member 132 is adjustablysecured to a member 296 bymeans of=screws 298, in order to provide for the accuratepositioning of the lifts in the lift-receiving devices, irrespective of the size of the lifts operated upon.

The member 296 projects laterally from the slide 300, which constitutes a part of the alining device 136, and which is periodically reciprocated towards and from the axis 126 of the turret in ways 302 (Figs. 3', 4 and that are secured ,to. portions 304 o'rojecting downwardly from the lower side of r the horizontal member 306 constituting'a part of the upper frame member 160. slide 300 is box-like in construction, being provided with an upper wall 308, sidewalls 8 10. 312 and connecting ribs 314: and 316.

Thereciprocationsof the slide 360 are effected in the following manner. The outer ends ofthe side walls 310'an'd 312 carry a pin 318 3 and which has, a pivotal driving connection with a socket member 320 that isprovided at the upper end of a tubular arm This arm is mounted for telescopic sliding movement within a hollow lever 324 and is normally urged in an upward direction by means of a coiled spring 326 that is disposed within.

lever, 330. A stop 332 constitutes a partof the lever 324 and is normallymaintained in engagement with an inclined stop surface 334 of the lever 330 by means of aspring 336 which is seated in a socket 338 in the lever 330 and which acts against a projection 340'of the lever 324. The lever 330 forms a part of a yoke 339, the opposite ends ofw'hich are pivotally mounted upon a rod 342 that is suitably supportedinthe pedestals 156 and 158. The forward end of the yoke 339 is provided with an arm 344 carrying a roll 346 which cooperatively engages a cam path in the cam 198. I This cam is designed to periodically reciprocatethe slide 300 in proper timed relation to the other mechanisms of the machine to'efi'ectthe delivery of a dry base-lift into each of'the receiving devices .128 asthey are successively positioned at the first station, andwalso to concurrently efl'ect the alinement of the componentlifts of the loosely assembled heelat the fourth station, as will hereinaftermore fully appear. Obviously, the purpose of the spring-actuated, telescopic connection is to insure proper operative engagement, of the socket member, 320 with the pin 318 as the cam 198 effects theactuation of the slide 300, while the yieldingconnection effected through theagency of the spring 336 between the arm 324 and levern330: introduces an element of resilience in the driving mechanism forthe slide to prevent undue strain or breakage ,in the event that an, obstacle is encountered during .its forward feed movementy *While the base-lift is being deliveredto the lift-receiving device 128 occupying the firststatiom it is of course essentialto main tain the lifta'eceiving: device at the proper height for the transferral and deposition of the base-lift. For this 350 (Figs. 3, 6 and :7) is provided for engaging the radially projecting lug366 of the car'- rier arm238 occupyingthe first v station and for limiting the upward movementgof Ithe lift-receiving device in opposition to-the action of its spring 250; This stop arm 35 0 constitutes a part of a bell crank :that is .pivotally mounted upon a stud'352, which projects from the side of the pedestal 15 8 and whichis provided with another arm 35 8 dependent therefrom and carrying at its lower end an adjusting screw 360. which is adapted to engage the edgeof a portion 362 of the pedestal 158.. By suitably adjusting the set screw 360, the stop arm 350 may be properly positioned to limit. the upward movement of the lift-receiving device inaccordance with whatever height of-heelis to be built. .It is desirable,of course, to avoid any shock to the apparatus when the-upward movement of thelift-receiving device is arrested by thearm 350.. Therefore, a torsion spring 354. is disposedabout the stud352 in purpose, stop arm such manner as toeffecta gradual andyields ing limitation to the elevating-moveinent of the lift-receiving device. 7

Referring particularly to Fig. the pasted lifts of the heel-pile are delivered in rapid succession upon the previously sup plied drybase-lift in the liftq'eceivingdevice 128 at the second or assembling station, during which delivery the lift-receiving device is progressively depressed' as the lifts are successively deposited. The apparatus is so constructed that during the delivery of the pasted lifts, the height of the heel-pile is measured to determine whether ornotany of the lifts are missing, in which event means is provided for automatically releasing the detent or stop 108 which maintains the main control lever 98in operating position, whereupon the main clutch of the niachineis disengaged and the operation ofthe machine is discontinued. The accomplishe .ment of this purpose is efi'ectedhy the means and in., the mannerv now to be described, which..means may, for convenience, ,be termed-the automatic; trip mechanism. l-laving. preliminarily adj usted the receiving devices. 128 with respect to the carrier arms 238 in accordance with the height ,of

the heels .to be built, the measurementof the heel is determinedv by the depression of the carrier arm 238 uponwhich the lift-receiving device, being loaded, is mounted,and if the proper number; of lifts have been-delivered, an -'outwardlyand radially project ing lug 366 (Fig. 2) ment with one end-of a lever 368 which is pivotallymounted at .370 intermediate its ends. However, if any ofthe lifts are ,missing, the lift-receiving device is not depressed far enough to cause the ln and actuate the lever 368.

In the event thatthe-lever-368 is actuated, th'e'end-thereof, which engages an arm 372 (Figs. 2, 4, and.5) that is fixed to-ja transverse rod 374, is rotated in a counter-clockwisedirection, thereby moving-the pawl 134,1which is also secured to the rodr374 a=t its'rear end,.into the position shown; in-Fig. 2and against the action of a tensionspri-ng 376. The'ends of the spring 376 are respectively secured to a pin-B78 on-an arm. 380

secured to the rod 374 aud toa bracketr382 which is secured to-part' of the-supporting frame'of the machine andsupports the rod 374. In the position shown in' 'Fign 2, the pawl134 which is pivoteddirectly"beneath the clriveshaft-122 is in such position as not to beengagedzby 11110303111133 secured to the shaft 122,:so that thelrod 374 remains in a position of rest. I A However, if there is a failure to deliver one or more of the component lifts ofthe heel into the lift-receiving,device, said .device is depressed. insufficientlyitoicause the e 3 6.4 engage th M368; s tee is brought into-engageg 366 to engage the rod carrying the spring-pressed detent or stop 108 to remove said detent from engagement with the latch 104 carried by the control lever 98. In this manner, the control lever 98 is automatically released and by me'ans of the springs 103 and 78 is thrown into its stopping or inoperative position, as shown in 'Fig. 6, under which circumstances the main clutch is'di'senga'ged and the operation of the machine automatically arrested. The operator is thus given an opportunity to supply the .inissing lifts after which he may mnuauy'rest ore the ojeration "of the machine bylsiiitably actuating the control lever 98.'

From the "foregoing description, it will be understood that the automatic trip mechanism is so constructed and arranged that the "clutch will be ai'itoinatically disengaged at every cycle of the machine unless a proper number of lifts are delivered to the lift-receiving deviee at the assembling smtion, in which case the mechanism is actuated to prevent the functioning of the cam 133 and to permit the operation 'to continue. Obviously, the inertia or the moving parts is such that the machine cannot be brought to rest instantaneously and, therefore, in order to prevent the breakage "of the auto matic trip mechanism, means is provided for positively retracting the pawl 134 from engagement with the cam 133 as soon as the control lever 98 has been released andac ftu ated to its stopping position. This is effected through the agency of a control lever eiiten'sion 394 (Figs. 4 and 18) which is normally engaged by the weighted end of a lever 396 that is pivoted at 398 upon a member 400 secured to or constituting a part of the bracket 382. The upper enlarged end or the lever 396rests against an arm 402 that conveniently constitutes an integral part of the pawl 134. With this construction, as soon as the control lever 98 is moved to its stopping position, its e2";- tension 394 turns the weighted lever 396 about its pivot 398 through the engagement of its upper enlarges end and the arm 402. The pawl 134 is thus positively i'etracted from engagement with the cam 133, whereby the parts of the trip meehanism are relieved of str'ain to which they would othermal gravity position, tliu s per nitting the erative position and to function thereafter in the manner already described. In order that the automatic trip nech'a;

nisin may operate to properly throw out the 134 to be restored to itsnormalQ'inop;

clutch, irrespective of the height'of the piarticular style of heels being'bu'ilt, it is necessary that. the liftieceiving devices 128 be preliminarily adjusted with respect- "to the several carrier arms 238 b y means ofjthe sliding adjustable connections, and adjustt ing screws 240 already referred to.

The inner surfaces of these members are so shaped and in clined as to correspond to the. ultimate side slope of the heel to be produced, and each member 138 is provided with a shoulder 418, the purpose of which will be later The rigid alining members 140 are detachably secured by means of screws 422 to the forward ends 424 of the'side walls 310 and 312 of the slide 300, and the forward extremities of these alining members 140 are so curved and inclined as to conform to the curvature and the ultimate rear slope or pitch of the heel to be built. l/Vhen building heels of different styles, the alining members 138 and 140 are replaced by similar members of the proper dimensions and configuration.

The alining device 136 is reciprocated as a unit in a rectilinear-path towards and from the lift-receiving device 128 occupying the fourth station by means of the cam 198 and the actuating mechanism operated thereby and hereinbefore described in connection with the pusher member 132. Prior to the advancing movement, the alining device 136 occupies the position shown in Fig. 8. Upon advancing the alining device, the forward ends of the resilient supporting members 416 and also the side alining members 138 successively engage the lateral surfaces of the heel held in alining position in the receiving device. As the alining'device is advanced,

the resilient supporting members 416 and side-alining members 138 are forced outwardly, and by reason of their wiping engagement with the lateraledges of the lifts, effect the lateral alinement thereof, while they always tend to force the heel against the breast gage 232. Before the alining device reaches its forward limit of travel, the shoulders 418 of the side-alining members 138 are advanced bevond the heel and are snapped into the position shown in Fig. 9. At the same time, the rigid alining members 140 are brought into engagement with the curved rear edges of the lifts and positively force them forwardly against the breast gage 232 of thelift-receiving device, thereby insuring the proper alinement of the breast surface of the heel. Substantially concurrently with these operations, the forward ends of the resilient supporting members 416 are brought into engagement with inclined cam surfaces 426, constitutinga part of the bracket 172 that is suitably mounted upon the frame. The cooperative engagement of these cam surfaces 426 with the forwardexiremities of the resilient supports 416 causes the side-alining members 138 to be squeezed together under considerable pressure, during which action the final lateral alinement of the lifts is effected and insured.
