Original application filed october 24', 1918,

This invention relates to hcelbuilding ma chines, and more particularly to that class of machines adapted to'form a heel, or part of a heel, from a series of lifts previously died out of leather, leatherboard or equivalent sheet material. i

The various features of the invention are herein shown and described as embodied in a machine which is completely automatic in its operation. It should be understood,

however, that the utility of many. of these features is not restricted to a completely automatic machine but that they may advantageously be employed in other connec-. tions, in. heel building; machines which are only partially automatic in operation.

. A principal object of the invention is to produce a heel huildingmachine which shallbe capable of operation at a high speed with great certainty and accuracy and which shall produce heels of a uniformly high quality with :a minimum of care and skill on the part of the operator;

With this end inview, one feature of the invention comprises an improved lift assembling mechanism,including a support upon which a row of heel lifts may bedeposited, in combination with unidirectional leans operating in a single movement to collect the, lifts in a heel pile in a suitable form or rece ver. By the provision of a port in proper collecting device movable in one direction only a considerableadvantage in speed and ease of operation is gained over machines employing collecting devices ,of the reciprocating type wherein a substantial amount of time is lost .infleffecting the idle return stroke of the collector; This feature of the invention may be embodied advantageously in an endless carrier orcha-in provided with seriesof spaced apart; depending lift engaging fingers movable along the lift suptime relation to'the deposit C. Smnrons,

Serial No. 259,578. Renewed December 2, 1920. Serial No. 427,847.

of series of lifts thereon, in combination with means for moving the carrier intermittently through distances sufficient to produce complete heel piles.

Another feature ofthe nvention resides in the provlsion, in combination with mechaheel lifts into a pile, of means for producing a dry or unpasted lift and assembling it 'with; those which are pasted, in such a manner as to avoid any application of paste to that surface of the dry lift which is destined to become an outer face of the heel blank. As herein disclosedpthis result is accomplished by producing and advancing the drylift to the heel form in a path out side of the path of the pasted lifts, thus keeping 1t out of contact with those parts ofthe machine which may have received.

paste from the pasted lifts: This lift thus is kept dry and clean until the first pasted lift is deposited upon it. Preferably, the drylift is produced and advanced to the heel assembling form in a plane above the path in which the pasted lifts are advanced and is dropped into the form in advance of the first pasted lift, which is deposited upon the dry lift, leaving the lower face of the latter clean and untouched by the adhesive.

A further feature of the invention relates to the provislon of a heel 11ft assembling form, having HDPIOVGCl'IIlGEI'IlS for causing its bottom member to descend gradually to deepen'thelift receiving cavity as successive lifts are delivered to it, and subsequently to rise until it is flush with the top of the form to permit the heel to be removed horizontally. ln the illustrated con struction this lowering of the bottom of'the heel form is controlled by a cam timed to co-operate with the lift collecting-mechanism, which may advantageously be con trolled by a cam upon the same cam shaft. Still another feature of the invention has to do with the combination, with a heel form and a presser member for pressing heel l ifts together in the form, of a lift collecting device passing directly through the presser member. An important advantage of this arrangement is that it is not necessary to retract the lift collecting device to permit the operation of the presser.

Other features of the 1nvention, more or IllSIIl for pasting and collecting a series of ing the following detailed description, in

. Fig. 6 is a front elevation view ings illustrating one embodiment of the invention, it being understood that variations in the several features may be employed without departing from the spirit of the in vention, the scope of which is defined in the appended claims.

The terms heelf heel blank and heel pile are'used interchangeably throughout the specification and claims to denote a pile of lifts assembled in proper relation to form either a complete heel or a multi-lift section or deck suitable for assembly with other lifts to form a complete heel.

Referring now to the drawings:

Figure 1 is a front elevation of a machine embodying the invention;

Fig. 2 is a right-hand end elevation;

Fig. 3 is a view partly in elevation and partly in cross section illustrating the pressing, ejecting and nailing devices;

Fig. 4 is'a detail ofthe means for rotating the nail driver turret; Fig. 5v is a plan view of the left-hand end of the machine with portions broken away; showing details of the means for pasting and guiding the lifts to the form; and. a

Fig. 7 is a cross section on approximately the line 7, 7 of Fig. 6.

The frame of the machine comprises a bed 10 supported by legs 12. The continuously running pulley l4, driven from any suitable source of power, is arranged to be operatively connected, at will, to the mechanism of the machine by a clutch arm 16 operated by a foot treadle 18. This connection is effected by clutching the pulley to a driving pinion 20 which meshes with a gear 22 rigidly mounted upon a cam shaft 24 which extends the entire length of the machine. To this cam shaft are secured the cams which effect or control the operation of the lift producing pushers, the collecting chain, the driver turret, the ejector mechanism, the presser anvil and the nail drivers.

The supply of heel lifts, which may be of graded sizes or all of the same size, is contained in a series of adjustable magazines 26, 28, and the individual lifts are produced one from the bottom of each magazine, simul taneously, by a series of push plates or pushers 30 reciprocated by a sliding bar 32 which is actuated by mechanism to be described hereinafter.

In the forward movement of the pushers 30, a row or series of lifts is producedand deposited in dispersed relation upon a supporting surface 34 upon the bed 10. The lifts thusdeposited areindicated at 36.

A carrier in theform of an endless chain 38 passes around an idle sprocket 40 at one end of the machine and a driving sprocket 42 at the other end. The driving sprocket 42 is secured to a shaft 44 upon which is also mounted a pinion46 meshing with a vertically reciprocable rack 48 and carrying a radial arm 50 provided at its outer end with a pawl 52 arranged to engage in a suitably formed notch in the interior of the sprocket wheel, as shown in Fig. 1. It will be apparent that movement of the rack 48 downwardly will, through the pinion 46, arm 50 and pawl 52, cause rotation of the sprocket wheel in a clockwise direction, while upward movement of the rack will have .no effect 'upon the sprocket, the pawl passing idly by the notch. An idle sprocket 54 is carried in the outer end of the arm 56 of a bell crank lever, which is loosely pivoted on the shaft 44 and has a downwardly extending arm 58 provided with a slot 60 and arranged to be adjustably secured to the stationary bracket 62by a bolt 64. The purpose of the'idle I sprocket 54 is merely to support and keep taut the collecting chain.

The lift collectingcarrier or chain is provided with three series of depending, rearwardly inclined collecting fingers 66, each equal in number to the number of magazines plus one and all except the one at the left (see Fig. 1) being spaced apart equally with the spacing of the magazines' The left hand finger is spaced further from the remaining fingers and is placed in position to engage and remove the completed blank from the heel form immediately upon the beginning of the movement of the chain.

It will "be understood from the preceding description that the movement of the chain 38, which is effected by the driving sprocket 42, is always in the same direction, that is to say, the lower or operative section of the chain always moves toward the left, as viewed in Fig. 1. For the purpose of effecting this movement, a cam 68 is provided upon the shaft 24. This cam is en gaged by a cam roll 70 onan arm 72 which is loosely pivoted at its rear end upon a rock shaft 74 and has, at its forward end, a toothed segment 76, meshing with a pinion 78- upon. a short shaft 80. Also secured to the shaft 80 in fixed relation to the pinion 7 8 is a gear 82 arranged to mesh with'teeth 84 cut in the front face of the rack 48 which is guided for vertical movement in the bracket 62 and the gear casing 86. In one revolution of the cam 68 the segment arm 72 is moved down and back, turning the shaft 80 first in one direction and then the other. Q0

The consequent rotation of the gear causes the rack 48 to be moved first downwardly and then upwardly. The pinion 78 and the gear 82 are so proportioned that the downward movement of the rack 48 this in turn produces a movement length, that is to say, a distance equal to the extent of one of the series of collecting fingers. 'The position it in whichthechain stops is such that the fingers 66 occupy positions between adjacent magazines and the lifts producethfrom the magazinesby the pushers are deposited upon the support 34 in dispersed relation between the respective collecting fingers. as is clearly'apparent in Fig.1; I i v ff The pusher actuating; bar is operated by a cam 88upon the cam shaft 2 1. A cam roll 90 engaging the. cam 88 is carried in the forward end of an arm 92 rigidly secured to the rockshaft 741. Twoupwardly extending arms 96, 98, also rigidly secured tothe rock shaft connect the latter tofthe pusher bar 88 effects a complete oscillationof the rock shaft 74 and .consequeiitlyfa complete reciprocation, forward andback, of the push ers.- This is timed so to occur as to deliver the series of liftsiunon'the support 34 at the time whenthe collecting chain 38 is sta tionary.

Parallel guide members 100, 102 are provided upon thesupport 3 1- forkeeping the series of lifts deposited, upon the support straight and. in; :alinement; These guide. members are securedito thesupport by bolt and. slot connections 104e,; permitting relative adjustment of the guides toward or from each other to accommodate lifts of different sizes. i

i The bottom 106 of the-left-hand magazine is located in a plane spaced somewhat above the support 34:, and the corresponding pusher 108 is also located ina correspondingly 30, The member .106 extends forwardly partially acressthe lift support 34, as shown at 110 and co-operates with a plate 112 supported in from itby a distance suflicient to permitthe passageflof the collecting fingers th'erebe-. tween to receive the lift produced from the magazine 28. This is the sO-calleddry, or unpasted lift of the heel. The guide members 100 102 are built up higher adja centto the supporting members 110, 112,to guide the dry lift upon its way to theheel form. The left-hand ends of the said supporting members are deflected downwardly, as shown most clearly at 11am Fig. 6, leading; to the top of the form" recessor cavity.

The heel'form comprises an abutment 116 alining the breast edges of, the liftsiand'a off radially adjustable form jaws 118 co-operatingtherewith, The bottom ofthe heel form consists principallyof an ejector member 120,,which is vertically movable within the jaws and is'pro-vided with passages 122, through WlllCllltllQ heel building nails may be driven, The eyector 120 1s reciprocated vertically by a cam 121 I engaged One revolution of the cam higher planethan that of the pushers l the same plane but spaced by a cam roll 126 upon' a lever 128 loosely pivoted at its rear end upon the rock shaft 741. The center line of the cam 124 is1ncheated by long and short dots in Fig. 3.

The forward end of the cam lever 128 is connected by a link 130 to a head 132 guided to slide'vertically upon a member 134, depending from, thetable 136 which carries the form jaws. The head 132 carries the l ejector 1120 which partakes of the movenents of said head. Theejector cam 12 1 s so designed and timed that it descends gradually to deepen the form cavity while i i the liftsare being delivered serially and piled up in the form.

The lower side of the ejector is recessed at 138 to fit down over either of the nail blocks 140 carried at the extremities of the arms of a turret 1 12 mounted upon a vertical shaft 144 to rotate in a horizontal plane. Beneath each nail block is a driver plate 146 carrying nail drivers .148. Each driver plate 146 is slotted, as shown at 150, to fit over the head 152 of a driver plunger 15%,

which is reciprocated vertically at proper times by a cam 156 uponthe cam shaft 24.

This cam is engaged bya cam roll 158 on a cam lever 160 pivoted loosely at its rear end upon the rock shaft 7 1 and connected by a The shaft link162 to the driver plunger. 14:4: supports loosely a pinion 16t, with which meshes a horizontally reciprocable rack 166 connected by a link 168 to a. cam

lever 170 pivoted at 172 to a stationary bracket 17 1. The cam lever 170 carries a cam roll 176 operated by a cam 17 8 upon the camshaft 24 The hub 180 of the gear 16 1 is notched at opposite sides, as shown at 182, and a disk 18 1 pinned to the lower end i of the shaft 1 1 1 carries a pawl 186 arranged to enter the notches. It will be apparent that when the cam 17 8 operates to move the rack 166' to the right, as viewed in Fig. 3,

the gear 165 C and its hub 180 will be rotated thrdugh half a revolution in the proper directionto rotate the turret shaft and turret I through the same angle while the return stroke of the rack 166 will be idle, byreasons of the one-way pawl and ratchet connection between thehub 180 and the disk 18 1.

Afterthe lifts have been assembled in the form, it is necessary to press them together, and, if it be desired to drive one or more heel buildine nails, to hold them under pressure while this isbeing done. This presslng is accomplished by a presser or anv1l 190 mounted to reciprocate vertically in a suitable stationary guide 192. The anvil is con nected to the forward end of a lever 1% which is pivoted at. its rear end to a sta- .t-ionary bracket 196. A rodl98 is pivoted at 200 to the lever 194 and, at itslower end, is connected to a lever 201 having at its forward end a cam roll 202whicl1 is arranged tor engagement with a cam 20% on the earn in orderly arrangement.

shaft 2%. 1-1 stiff spring 206 surrounds the rod 198. The lower end of the spring bears upon a collar 208 secured to the rod, and its upper end bears against the under side of the table 136. As may be seen by'reference to Fig. 8, the cam 1- is so shaped that in its rotation the anvil 190 will be gradually raised, compressing the spring 206, and then suddenly released, whereupon the expansion of the spring will cause the anvil to be forced suddenly downward, striking the heel pile ajsharp blow and forcing it firmly into the form. A slot 210 is provided in the anvil or presser member 1 0,, and the collecting chain passes through this slot.

A paste roll 212 is mounted for rotation in a tank 214 subjacent tothe path ofithe lifts along the support 34. An adjustable scraper 216 serves to regulate the amount of paste carried upon the surface of the roll. Resilient fingers 218, pressed yieldingly by coiled springs 220 serve to press the lifts down upon the paste roll as they pass over the latter. 7 I

Supporting members 222, extending beyondthe form and flush with its top, receive theejected heel and guide it to a delivery position where it may be. deposited in a suitable device for conveying the heels away Such a device is indicated at 224, see Fig. 1, and may consist of a conveyor such, for example, as that disclosed in the copending application of Thomas Lund, Serial No. 258,849 filed Oct. 19, 1918. This conveyor may advantageous- 1y conduct the heels directly to a heel compressor, and the use of the machine of the present inventionis particularly advantageous in this combination, since the operation of assembling or piling up the lifts in the form follows so nearly instantaneously upon the application of the paste that it becomes possible to use an exceedingly quick drying paste with no risk of its setting or loosing its adhesive quality before the lifts are brought together. It is possible to compress freshly built heels immediately afterthey are assembled only when a paste of this type is used.

The operation of the machine s as follows: Assuming that theinachlne has been stopped in the position shown in Fig. 1,

with a finished blank resting upon the ejector 120 and the ejector raised until it is flush with the top of the heel form, and a series of lifts deposited upon the support 34 ready to be assembled, the machine is started. At this time the pushers are in the retracted position illustrated in Fig. 5. Immediately upon startingthe machine the chain carrying' the collecting fingers 66 advances toward the left, as viewed in Fig. 1, through a distance equal to one-third of its length. a The first finger engages the previously finished blank, pushing it off the ejector 120, across the support 222 and dropping it in the conveyor 224-. The next finger engages the dry lift upon the supporting members 110, 112, advancing it along said members and dropping it upon the ejector, which by this time has descended below the tops of the jaws 118 so that the lift is retained in the form and the lift engaging finger passes over it. The following lifts of the series are advanced by their respective collecting fingers successively over the paste roll 212 and deposited one ontop of another in the form. During all this time, the ejector 120 is descending and has reached; a position where it is flush with the table 136 by the time all the lifts deposited the collecting chain stops, and the anvil 190 descends sharply, pressing the lifts compactly together and holding them under pressure. Prior to the descent of the ejector, the nail driver turret will have reached the positionshown in Fig. 3, and the ejector, descending to the position indicated in dotted lines, the nail block 140 will enter the recess 138 maintaining the passages inthe nail block in line with those in the ejector. The drivers are now actuated to drive the heel building nail-or nails upwardly out of the nail bloock through the passages 122 into the heel, the nails being clinchedupon the anvil 190 if they are sufficiently long. During the nailing operation the pushers 30, 108,

are advanced to produce a new series of lifts and deposit them'upon the support 34 between the fingers of the next series which have now arrived in receiving position.

After the nails are driven, the ejector and anvil. rise simultaneously. the anvil, how ever, moves faster than the ejector and consequently when both have arrived at the upper limit of their movement the anvil is separated from the heel, as shown in Fig. 1, permitting the heel to be discharged. Immediately after the ejector 120 has risen sufiioiently to permit the nail block 140 to become disengaged from it, the driver plunger 15 1 being at the same time retracted,

the turret 1412 is rotated through half a revolution to remove the now emptied nail block and bring into operative position the other nail block and drivers to which nails have been supplied by. any suitable mechanism while it was in the left-hand position, shown in Fig. 3'. The parts are all now in the same position as when the machine was started, and the operation may be repeated indefinitely as long as the supply of lifts is maintained in the'magazines, a complete heel pile or blank being produced at each cycle of such operation. 1
