To all whom it may concern: I

Be it known that LERAs'rUs E5WINKLEY, a citizen of the United States, residing at Lynn, in the county ofjEsseX andstateof lvlassachusetts, have invented [certainlm provements in Heel-Building Machines, of which the following description, in cennecspecifioation, like referen'cejcharacters on the drawings indicatin'glike parts in the several figures. f This invention relates to heel building machines, and more particularly to that type of heel building machine whereby a plurality of lifts or pieces ofleather, or other material, are fastened together toform a heel.

Heretofore it has been the common practice to, build heelsby ,manually assembling a number of lifts,gone on top of the other, in a mold, and fastening them together by one or more fasteningsor-nails driven. into the pile of lifts while under pressure. In the operation of heel building,.the height of the resultant heel has depended upon the skill and care of the machine'attendant in placing the required number of lifts of properthickness in the mold, and, as a result, heels of a series have not beenuniform.

Lack of uniformity in theheight ofsuccessive heels in a run of heels, and the 0bjections thereto, may manifest themselves not only after the heels are attached to the boots or shoes, but'also during the treatment to which the built up heels are subjected after or before leaving the heel building machine. For instance, the heel lifts have'their contact surfaces provided with' an adhesive or glue, and in order that the contour edges of the lifts may be held in closeconta'ct when the heel is finished, the built up heel is placed in a heel press where the heelis' subjected to pressure foratiine sufiiciently.

long to enable the glue or adhesive to. set or becomedry. If, however, the heels built in the heel building machine are not ofthe proper height, or too low, the fastenings or nails which secure the lifts together, may

not be driven completely into the pile of lifts, and such projecting nails will not permit the heel liftstoireceive the desired uniform pressure of the clamps when in the heel press. This may result ineracks' appearing between the heel lifts when at.-.

tached to the boot or shoefland finished, or worn. 1

I EEL-BUILDING Macrame.i

1919. Serial no. 311,968.

Attempts hai e been made to: overcome this "objectionable" variation in the height of built-up heels produced in the heel-building machine, by the use of gage plates arranged in'pil'es about the support for the heel lifts,

so, thatftlie mac'hine' attendant could feel the gage plates withone hand, and with the other hand select thelift or'liftsof the proper thickness tobring the heel up to the desired height. In this, as in the older method however, the care andskill of the machine attendantfdeterininesthe height of thefpile of lifts, and, consequently, variationsin the heights of the heels result.

more satisfactory solution of the "prob:- lem, however, is furnished by the machine of "the" United States patentlto John R. Richardson No. 1,148,716, dated August 3, 1915, wherein automatic inean's is provided for measuring the height of thepileof heels assembled for. treatment in the heel builder,

In this machine a measuring means actsto e'ineasure' the pile of lifts before they are put under pressure, and if the pile is not inaccordance w th a" predetermlned standard,

operation fof the securing means is" pre vented, and the'attendant mayfcorrect the inaccur'2;cy. This-has resulted in a reater uniforniityv in the height of a run'o built-' up heels,'and issatisfact0 ry and efficient in operation. It is desirable, however, that the height .of' the finally completed: or, compressed ,pile of heel lifts may b e uniform, and not that the 'fastenings' of nails be not driven intoth'e pileof lifts 'to secure them together. The material of the lifts, for instance, may not always'be uniform in characte'ijso that while successive pilesof heel hits-may .n'ieasure the same height before they ,21'6 subjected;,topressure, they may vary inheight after "compression. An important feature" of thepresent in VClliilOl],.tl'l6l6lO l, consists ofmeans for pre- Venting'the operation [of the securing means a when a pile of heelj liifts under compression does not conform'toapredeterinined standard. The consequence ofthis'is that'when the machine is adjusted for building heels of a certain height and securing the lifts together' only' whenthe pile of compressed lifts correspondsto a predetermined height,

successive 'heels treated by the machine will beef substantially" the' same height. v l vhenthe heel lifts are placed'i'n' the heeL building machine, they are usually positioned relative to the front of the machine by the heel breast which bears against a breast gage or finger. Some machine attendants prefer to have the heel breast facing towards the rear of the machine or away from them, others. prefer that the heel breast be facing towards the side of the machine, and still others prefer it facing the front. Thesevarious preferences are incidental to individual characteristics which enable the attendant to place the heel lifts in position for treatment with greater facility when the breast ofthe heel faces in some particular direction. 2

Another important feature of the present invention, therefore, consists in providing a lift support which may be adjusted into different lift assembling positions to place the breast gage so that it shall face in different directions relative' to the front of the machine. This feature of the invention may be variously contrived,but in the presthe operating parts of the machine and cause improper operation and wear or breakage of parts. Another important feature of the invention, therefore, consists of providing a. receptacle beneath the heel lift support and surrounding the fastening inserting, or driver, mechanism for catching the adhesive or glue expressed from the lifts when subjected to pressure,in combination with a deflector to deflect the adhesive or glue away from the operating parts into the receptacle.

The invention further consists in certain features of construction and novel combinations of parts, which will be hereinafter described in the specification and in addition to the above, pointed out in the claims.

In the drawings:

Fig. 4 is an enlarged section on the line 4 of Fig. 2; j

Fig. 5 is a detached detail showing the presser cam and parts of the measuring device, some of the elements being shown in section;

The glue thus discharged illustrated as a convenient means for explanation of the invention and its cooperative relation with parts of the machine.

The supporting frame may be of any usual character suitable for sustaining the operating parts and as shown comprises a base portion 1 from which rises the column 2 provided with bearings 3,4, in which is mounted thereciproca-ting rod 5 constituting part of the fastener-inserting or naildriving mechanism. The rod 5 hassecured to it a lug 6 to which is pivotally connected at 7, 7, the rods 8, the lower ends of which are connected at 9, 9, with an arm 10 ofa bell crank lever pirotally mounted on the machine frame at 11. The other arm 12 of the bell crank or rocking lever is connected by a link 13 to an arm 14 secured to a rock shaft 15,,mounted in the lower part of the machine frame and having secured thereto the treaidle 16,. the construction being such that by depression of the treadle 16 the rod 5, heretofore described, will be moved upwardly for inserting the fastening, or driving the nail or nails.

The' column 2 supports at its upper portion a head 17 to which .is bolted at 18 the bent arm 19 which constitutes the support for the upper presser member, as will more fully appear.

.i-rbove the head 17 is secured the receptacle 20 provided with a bearing portion 21 through wiich the upper extension of the rod 5 passes. The bearing portion 21 which may be connected to the receptacle 20 in a. manner to provide an adhesive or glue containing portion 22, extends some distance above the bottom or lower portion 23 of the receptacle 2!), the construction being such that any adhesive glue dropping from the'heel or running therefrom during thecompression thereof, may drop within the receptacle 20 and be sustained in the space 22 without danger of coming in contact with theoperatin parts of the machine, and more particulafly the reciprocating rod 5.

The upper end portion of the receptacle 20 serves to support a plate 241- which may constitute .a form of table. The support at may be connected to the top of the receptacle 20 by the flanges 25, and suitable securing means may be provided for holding the support 24 and receptacle 20 in associated relation. I

The support 24 has a hub portion 26 in whichv is mounted a nail block 27, the upper end portion of which, is provided with a flange 28 which rests upon the upper end of the hub portion 26 and may there-be secured in fixed position. The nail block 27 is provided with a passage way or passage,

which extends upwardly from: the driver head and enters the nail block, as indicated in Fig. 3. The cap '31 maybe secured to the driver head 30 by appropriate means, such as the bolts'33. i i I Mounted upon the top of the support 24 is the lift support 34, Fig. 3, which,-in the present instance of the invention,is of general circular shape in plan and mounted for rotative movement. about the axis of the nail block. A series of holes or threaded openings formed in the support 24 at intervals, enables the lift support 34 to be rotated about the axis of the nail block 27 and secured in rotated oradjusted position by suitable means, such as the, bolt 36, Fig. 3. In the present instance of the invention the lift support 34 has adjustably secured thereto the breast gage 37 and the side gages 38 which are secured in desired relation of adjustment to accommodate the heel lifts which are to be secured together. The breastgage may be variously secured to the lift sup port and rotate with it, and in thep'resent instance, is shown as providedwith a'slot 39 in the lower foot portion of the gage through which extends the bolt 40,'the construction being such that by loosening the securing bolt 40 the breast gagemay be adjusted relatively to the side gages to accommodate the heel lifts which are to be treated; The side gages 38, or fingers as they aresometnnes called, may also be secured to the lift support 34 adjustably, as by means of-the bolts 41, one of which is indicated in Fig. 3.

When the machine attendant desires to have the breast gage 37 in position facingto the rear of the machine, he or she turns'the lift support 34 until the breast gage 37 "is in the desired location and thereupon secures the lift support 34 in position by means of the securing bolt 36. If, on 'the other hand, the machine attendant should de'sire the breast gage 37 to be located towardsthe front of the machine,,in order to facilitate r I r an extent to produce the desired pressure the piling of the lifts uponthe lift support,

- stance, as a cap piece 47 threaded into the upx-is provided with, a threaded recess 49 in i which is adjustably "mounted the presser stem '50 carrying thepresser 51 ,Whicl1 con- :stitutes one of the presser-members for-exerting-pressure upon the heel-lifts placed {between them. In order to prevent rotative I movement of the plunger 43 as itis reciprocated in its-support, the lower end portion of;

- he-or she lunscrews the bolt 36, turns. the lift support 180 from? the position indicated in I Fig; 3-, and a then; secures the parts in the new position by means of the bolt 36.

, The arm 19, which 1 constitutes 2 one convenient meansi for. supporting: the upper presser member, is piovidedwith a hub portion 42, F 3, in which is mounted a plunger 43 having an enlarged head 44 between 'avhichand'thelower end of the enlarged chamber in the hub, is the spring 46,

normally tending to lift the plunger 43. The head-44 on theplunger 43 maybe held in, position by suitable means such, for inper end of the plunger and-affording a surface against which may act the presser cam 48. a a cap 31 for securing thereto the driver 32,

I iThe'lower end portion of-the plunger 43 the plunger43 has secured thereto an "arm 52, carrying-a pin 53 which rides inasocket 54 as the plunger is re-ciprocated. Suitable means may be'provided for preventing rotative movementof the adjustingrstem 5 0 of the presser to prevent disturbance'of adjust Inent during reciprocation of the plunger.

Rising fromthe arm 19 are thesupports 55, best shown in Fig.2, between which is mounted the supporting" pin or shaft 56.

Mounted upon the supporting pin or shaft 5 6 is the pressercani'48 jwhich' constitutes one convenient form of means for applying pressure to the heel lifts through the upper presser meniber, The presser cam 48 has itspresser surface 57 adaptedto contact with the 'headorcap portion 47 offthe plunger 43', the construction being such that tr'acloclrwise, view-ing 43will be depressed. t

Thepressure cam"48i1s provided with a 3, the plunger 'socketed or] recessed portion 58in which is mounted a spring 59, one end of I which, Y at 60, rests against the end wall of the socket'or recess anidfthe other end 61 of which rests upon a lug 62 carried a segment portion 63 of thecamactuating means, which, inthe present instance of the I invention, comprises 'a handle 64 and yoke 65 having a'hub op 1 10 upon rotative movement of the cam 48 coni upon the heel. lifts mounted on the lift support, and the pile of heel lifts has been compressed, it is desirable that the height of the compressed pile of lifts may be measured, and if either too high or two low, that the fastening or nail be not driven into the pile of lifts to secure them together.

Pivotally mounted at 66 on .the machine frame, or, as in the present instance, upon the arm 19, is the measuring lever 67, the lower end 68 of whichengages a locking member which, under certain conditions, to be hereinafter described, prevents operation of the heel liftsecuring means or driver. In the present instance of the invention .the locking means consists of a slide 69 mounted for reciprocating movement in a bearing 70 sustained upon the machine frame, and connected to the lower end of the measuring arm 67. The connection between the measuringxarm 67 and the slide .69, in

the present instance, consists of a' slot 71,

formed in the .end of the slide 69 through which the end 68 of. the measuringlever extends, the construction being such that should the measuring lever, 67 be moved about its pivot 66, the slide 69 will be reciprocated- Mounted upon the rod 5, which, as heretofore explained, constitutes part of the operating mechanism of the securing means, is a stop collar 72 which may be secured in desired position on the rod by means of a set screw 73, Fig. 4. The collar 72 has a flange 7 which, when the rod 5 is in its lowered or. inoperative position, is below the end of the slide 69, as indicated in Fig.1, so that the rod 5 cannot be raised when the slide 65 is extended inwardly over the flange 74, as indicated in Fig. 1, and, perforce, the

securing means or driver cannot be actuated. The presser cam 48 carries a lug 75, Fig. 6, having a. beveled surface 76 which is adapted to be engaged by a reversely beveled surface 77 on a lug 78 extending from the segment 63, the construction being such that the spring 59 normally maintains the beveled surfaces 76 and 77 in contact.

The measuring lever 67 hereinbefore referred to, has an upwardly extending arm 79provided with a roller or side extending pin 80 which is adapted to rest upon the contour or peripheral surfacesofthe lugs and 78 when the partsare in closed or normal position. When the presser cam 48 is in a position of pressureand the pile of compressed heel lifts conform to a predeterminedstandard,-the roll on the" measuring arm rests at the junction between the lugs 75 and 78, and as the cam actuating means, in this instance the handle 64, is further turned, the lug 62 is moved against the tension of the spring 59 while the presser cam 48 remains fixed, the effect being that the lugs 75 and 78 areseparated and the roll 80 may move inwardly under the impulse of the spring 7 9*, as indicated in Fig. 3, thereby withdrawing the slide 69 from above the flange 74 of the sleeve 7 2 and permitting operation of the securing means or driver. If, however, the pile of lifts is too 'highwhen the presser cam 48 is actuated to lnlPillhPTGSSllIB thereto, the position of the lug 78, while separating from the lug 75, will be such as to interrupt the inward movement of the roll 80 and, perforce, withdrawal of the slide 69 from its locking position'. The result is that under the condi tions stated, the securing means or driver cannot be operated and the fastening or nail will not be driven. On the other hand,

should the pile of heel lifts be too low, the

presser cam #18 will be moved farther than when the lifts are of the proper height, and will interject the projection 75 into the path flofmovement of the roll 80, with the result that again the slide 69 will remain in locking position and prevent operation of the securing means or driver. Thus it will be seen that the measuring means measures or de-- termines the height of the pile of lifts while they are under pressure and if the pile of lifts be either too high or too low when under pressure, the measuring device will prevent operation of the securing means or driver.

lVhen the pile of compressed heel lifts conforms to the predetermined standard, and the measuring device therefore permits operation of the securing means or driver by inward movement of the roll 80, it is necessary to 1no .'*e the roll 80 outwardly to restore themeasuring device to its normal position after the fastening or nail has. been driven and when the presser cam is moved to its non-pressing position. To offset this the present invention provides the yoke 65 ,to which the handle 64 is connected, with a setting cam 81 which, as the handle 6i is .IDOYGCl clockwise from the posit-ion. of Fig.

3 to that of Fig. 5, acts upon the roll 80 to move it outwardly, as indicated .in Fig. and past the tip end portion of a pawl 82 pivoted at 83 to the segment 6?), whereupon a spring 8a actin on the pawl, snaps it back into its normal position with the end of the pawl resting against the cam 81, as indicated in Fig. lVhen the pawl has snapped hack into position against the cam 81, after the passage of the roll 80, the contour surface of the pawl forms a traclt on which the roll 80 rides as the presser cam is moved into presser position asindicated in Fig. 3.

Should the adhesive or glue which is expelled from between the heel lifts while under pressure, find its way to the pressure sure against such-interference, the rod 5,

within the receptacle 20, isfprovided with a deflector 85, Fig. 4:, which may be conveniently formed as part of the driver head 30, so that should any adhesive or glue drop downwardly into the receptacle 20 it will be deflected outwardly from the rod 5 into the lower portion of the receptacle where all danger of interference with the securing means or driver is avoided i I WVhile the pre-sent'invention has special advantages in connection with a heel build ing machine of the general type herein described, it is not restricted thereto, but may be employed with advantageous results in connection with other forms of heel build ing machine to produce compressed heels of uniforrh height throughout the series.
