43 Claims.

This invention relates generally to means for mounting wood heels upon shoes.

In mounting a heel on a shoe, a common practice is to glue the cup of the heel to the heel-seat, and afterwards the flap of the sole is glued to the breast of the heel. The successful accomplishment of this stage in shoe-manufacture is dependent upon the proper location and retention of the heel on the shoe during the glue-setting operation. Unless the heel is properly placed and fixed on the shoe while the adhesive is hardening, the security of the fastening of the heel to the shoe and the appearance of the finished shoe are impaired. I have found, however, that if the application and maintenance of the pressure to the work is automatic or under machinepower, and the gluing of the flap to the heelbreast is done while the shoe-assembly remains rigidly clamped, the speed of performance of this operation is increased, while the accuracy of the work is practically assured, because the several parts are held securely in full View of the operator, the result being a greatly increased production, a saving in machine and labor costs and an improved product. In carrying out my invention, I prefer to employ a shoe-assembly-clamping means or heel-set, one embodiment of which I have described in Letters Patent of the United States No. 1,756,708, granted to me April 29, 1930, and which will hereinafter be briefly described, but I have made certain improvements in the construction and operation of said heel-set. These improvements more particularly involve the application of setting pressure to the clamped work by separate means, as a pedal actuated by the operator and mechanism functioning under the power of a machine in which the work With its heel-set or clamping members is supported between pressure-abutments; means, also oper-- ated under the power of the machine, for locking the clamping members in pressure-applying relation; novel means for fixing one of the abutments in the position to which it is moved; an arrangement for suspending the heel-set upon the upper abutment to facilitate the application of the work thereto; an unlocking organization for the clamp ing members; the combination with the heel-set of a flexible member arranged for contact with both the tread and rear of a heel and adapted to bend and otherwise adjust itself as to position when clamping pressure is applied; and flappressing means mounted upon the heel-set and movable thereon to urge the flap into engagement with the breast of the heel.

It. may be briefly stated that by the present embodiment of the invention provision is made V for applying glue or other adhesive to a heel by passing the cuppthereof over a power-actuated glue-feeding device, and the heel assembled on the shoe. Then, by clamping means co-acting with. my before-mentioned heel-set, the heeland-shoe-asse'mbly is. rigidly suppQrted' during succeeding operations. While so supported, an automatic power-actuated device is employed for pressing the'heel'on the'shoe,'and, in proper sequence, to operate alatching means conjointly with apressing means to grip the shoe-assembly in the heel-set. A resilient heel-pressing device carried byarid co-acting with the heel-set in cooperation with: a' shoe-rest: on thefsupporting' fram'e fixes the heel on the shoe precisely in the 60' T by the operative for facing the breast of the heel position previously determined by the operative in assembling the heel and 'shoeif Then apoweractuated rotary f'finishing deviceis manipulated preparatory to gluing the flap of the sole on the heel, andaflap-press, co-operating with the heelset, yieldingly forces the flap against the breast.

. The heel'being thus clamped to the. shoe and the flapclamped to the heel, the shoe-assembly as a unit is removed from the supporting frame.

After the glue, has hardened, the heel-set is removed with the aid of a mechanical device, and a powertrimmer. is employed to trimthe' overhanging part of the flap from the heel. This completes the operation. It is to be noted'that the shoeassembly, while'held in the supporting frame, is disposed with the shoe-bottom in full view of the operator, byreason. of Which the quality of workmanship enhanced. 1

speed of production is greatly increased and the I will first generally describe the improved heel-set and the shoe-assembly, In Fig. 1, A designates the heel-set, which includes a U- shaped shackle member I of suitable dimensions for receiving the usual bootor shoe-assembly B, as shown in Fig. 2. Preferably the member I is a generally formed as I have heretofore .set forth.

in the previously mentioned patent but having oppositely located shoulders 2 just above the bight of the member I, for co-action with a flappress,presently to be described. Disposed transversely of the member I, is a cross member or latch-plate 3 provided at its opposite ends with enlargements 4, '4 bored to fit the legs of the member I, whereby the plate 3 is disposed for.

' are slotted across the top of the plate to permit engagement with the legs of the member I,by

the outer ends of alined lockingor latch mem-' V bers 5, 55, mounted to slide upon the outer face of the plate 3. Each latch member is'formed with its outer end recessed to receive one of the legs of the member I (Fig. '20) and has its inner end inclined oppositely to a conical shoulder 'or This screw appearing, and is threaded into the plate 3 for co-operation with the latch members 5, 5, so that when the element 6 is screwed into the plate, the latch members 5, 5 will be so oppositely moved outwardly as to engage the respective'legs of the member I and thereby rigidly secure the members I and 3 together. Preferably, the spaced ends of the legs of the member I are slightly enlarged to prevent separation therefrom of the plate 3 upon disengagement of the latch members 5, 5.

The shoe-assembly B comprises a last I insertable in a shoe 8, upon which a heel 9 is to be s'ecured by an adhesive. The cone of the last may 7 be provided with the usual pin-hole I0. Disposed on the sole of the shoe 8 for engagement by the breast-edge of the heel is a shoulder I I for heel alining purposes, while the heel-cup contacts with the heel-seat on the shoe. This invention is particularly adapted for gluing on shoes heels'cf the spike or Louis type, and the practical requirement of heel-setting which it meets in a simple hardening of the adhesive the heel is firmly pressed uniformly on the shoe; I have accomplished this object by disposing the heel-set A on the shoe-assembly B, with the aid of a preferand highly effective manner is that during the ably .V-shaped slot, II provided transversely across the end of'the cone of the last 1, (Fig.

18) for co-action with the bight of the member I, so that the plane'of the member I, or the line of action of. the heel-set, will pass through the forward half of the'heel-seat on the shoe (Fig.

3), the precise location depending on the form a of the heel and shoe. 7 V heel-set will positively fix the heel as placed and over or become loosened. While the shoe-assembly is supported in the frame during the pressing and latching operations, presently to be described, after the set-and-shoe-assembly is removed from the machine, the heel and the shoe are held together by the heel-set, no screws or other interconnecting fastening For setting spike or other high heels, I provide When so disposed, thev means being emit is a practical impossibility for the heel to kickl file (Fig. 17) all mounted on a single frame.

a resilient bridging member or heel-engaging fixture C, shiftably supported from the heel-set A and interposed between the heel and the plate 3 of the heel-set. The member C is adapted for self-adjusting contact with the heel 9, bending as it spans the space between the rear face and the tread of the heel 9 across the plane of the member I or the line of pressure-action of the heel-set A. It comprises a preferably flexible body member or bridge-piece 12 whose rearward heel-faoe-engaging arm 13 carries a felt pad l3, or other yieldable covering and is curved to the approximate shape of the surface. with which it is to contact. The forward arm M of the bridge member has a lip I5 for engagement with the tread of the heel 9. of the plate 3 for sliding contact with the bridgepiece l2, to shiftably locate the latter in desired relation with the heel 9, is an arcuate seat It, the bridge-piece being loosely held to the seat by a screw or fastening element l1, preferably threaded into the screw 5 and movable in a slot in the member [2 as the fixture C swings on the plate 3 of the heel-set (Fig. 1

Having thus outlined the construction of my improved heel-set A and its heel-abutment C, a particular embodiment of a supporting frame or machine for use in connection with said heel-set will be described. Generally, the machine includes a shoe-rest D, co-operating with a foot-operated clamping head E and with power-pressure mech anism F. The machine also preferably includes a glue-applying mechanism G and a power-operated finishing mechanism H having a cutter or This frame includes a floor-plate i8 and standards l9 rigidly supporting a bed-plate 20. Rising above the bed-plate 20 is the shoe-rest D, preferably guided in a block 2! extending through, and secured to the bed-plate 20. The guideblock 2| forms a part of the pressure mechanism F and is provided with a passage 22 (Fig. 15) to receive the bight of the U-shaped member I. The heel-set A is so carried in the machine as to be vertically presented in shoe-assembly receptive position. For the convenience of the operator in mounting the shoe-assembly B in the frame, within and properly alined with the heel-set, I provide, rearwardly of the passage 22 and on the shoe-rest D, a pair of laterally spaced upstanding guide- fingers 23, 23, for loosely receiving the cone of the last I, and also an upstanding pin 24 between fingers 23 and inclined for co-ac-tion with last-hole I0. Between the guide fingers 23, 23, the shoe-rest D is formed with a last-engaging curved face 25, in order that the last-and-shoe-assembly B may'freely rock, with an amplitude limited by the engagement of the pin 24 with the walls of the hole 50 responsively to the pressing action of the head E (Fig. 15)

Fixed to the bed-plate 20 is a vertical, inverted L-shaped clamping frame 26, in the horizontal arm of which is slidably mounted the clamping head E adapted for adjustable movement towards or away from the shoe-rest D to accommodate different sizes of shoe-assemblies. Vertical reciprocation of the head may be accomplished by a shifting mechanism which includes a pair of racks 21 and co-acting pinions 21 connected, preferably through a yielding member or spring 28, to a foot-lever or pedal 29, the latter being provided with a releasable latching device 30. Downward movement of the. pedal 29 will result in yielding downward travel of'the head E'into Formed on the inner side engagementv with the shoe-assembly B upon the rest, D, the spring 28 thereafter yielding to permit the completion of the movement of the pedal 29 to latched position, as indicated in Fig. 3. It will thus be seen that the operator has only to depress the pedal to latched position to automatically adjust the head to any shoe-assembly. Said head may be retracted by a spring 28 on release of the pedal from the device 30. Depending from the head E, for alinement with, and reception of, the legs of the member i of the heelset, are a pair of preferably tubular plate-engaging members 3|, 3| (Fig. 5). Rotatable between the members 3|, 3 I, is a socket member 32 adapted to engage and rotate the hexa-conical head of the wedge member 6 of the heel-set A. The head E is thus advanced from the frame 26 for supporting the heel-set in position for operative co-action with the pressing mechanism F. To afford this support, the legs of the shackle member I are received by the tubular portions 3|, 3| of the head E, with the ends of the bight of the shackle in engagement with the guides 23, 23, and in vertical alinement with the passage 22 of the shoe-rest, the plate 3 being detachably supported from the head by a means to be described.

The dimensions of the heel-set A are so chosen as to accommodate the largest size of shoe-assembly B to be operated upon, and so that at its maximum upward adjustment, the plate 3 will be clear of the shoe-assembly as this is inserted into the heel-set for support by the shoe-rest D. As the plate 3 at this time is unlatched, and hence unless restrained may freely slide on the member I, I provide a pair of plate-engaging fingers 33, 33 (Fig. 16), slotted to receive the legs of said member. The fingers are mounted on the head E, being supported on a shaft 33 rotatable in a yoke joining transversely opposed C-shaped extensions 34, 34 depending from the members 3!, 3|, into which extensions the plate- enlargements 4, 4 respectively enter to rest on the fingers 33, 33 (Fig. 5). The fingers are normally urged upwardly by a spring to bear upon the plate-enlargements but, by a handle 34 secured to the shaft 33, said fingers may be swung downwardly and to one side'for the reception of the heel-set A. Thereafter, the fingers 33 are returned by their spring tov plate-supporting position. The plate 3 is thus suspended from the head E with the bight of the member I separated from it to the maximum extent, thus giving ample clearance to allow the ready positioning of the shoe-assembly B between the clamp members. The head E is actuated through the foot-pedal 29 to lower the plate 3 and clamp the shoe-assembly B upon the shoe-rest D, as best seen in Fig. 3.

The socket member 32 is suspended by a cage 32' from a clutch member 33 provided with a corrugated end-face adapted to co-act with a complementary portion of the socket member during the latching operation. Rotation is thereby so transmitted from a driving member that the clutch will yield to resistance of the socket mechanism F. In clamping the heel-set on shoeassemblies of different sizes, it is convenient to,

mount the shaft'3'l for reciprocation invthe head E, to accommodate. the clutch 36 to the socket member 32. as the latter finds its seat on'the screw member 6. The head is fixed in its adjusted position by a lockingdevice, including preferably a'double-ended handled clamping bolt 39 (Fig.

A 4), co-operating with a pair of members 40 pivotally supported from the frame 26 for oppositely pressing against the head a pair' of friction members or blocks 4!, 4|, slidable through opposing walls of the frame. So locked in adjusted position in the frame 26, the head becomes tem- .porarily a fixed 'abutment co-operating with the mechanism F.

As best seen in Figs. 17 and 18, a pressure-slide or lifting member 42 is reciprocable in the channel 22 of the shoe-rest D and has at its top a vi-slot 42 (Fig; 18) adapted to: co-act with the bight of the member I. At its lower extremity the memberreceives contact of an arcuate seat on one end of a lever 43 fulcrumed on a bracket depending from thebed-plate 20.

V The lever is acted upon by a spring 43 (Fig. 6), which urges a roll, carried by its other end against a cam 45, this causing the alternate advance and rethrough a counter-shaft 52 (Fig. 6) with an elec traction of themember 42 in the channel 22. The

cam 45, which includes a rising portion a, a rest portion b of approximately 190, and a falling portion c,is fixed on amain shaft 46 journaled in bearings'depending from the bed-plate 28; see Fig.2. Mounted onthe shaft 4fi'is a single-rota- I tion clutch mechanism generally indicated at 41,

receiving power from a gear 48 turning about the shaft 46. The clutch becomes effective on actuation of 'a clutch-lever 49 through a clutch-pedal 50, best seen in Fig. 2.

The clutch, details of which appear in Figs. 8,9, and 10, is so well known that no further description is necessary. The gear 48 may be connected by a train of gears tric motor 53 or other source of power supported uponthe bed-plate 28., By this means, the main shaft 45 may, at the will of the operator, be

caused to turn once, so the pressure member 42 will make one reciprocation. V A brake device J f (Fig. 7), including a friction band 2!) adjustably scribed as rotating in the head E, is actuated by a pair of bevel- gears 54, 55, one of which, as 54,

is splined to the shaft 3! to permit the axial movement of the latter. From the .bevel gears. 54,

55, the operating connections are through shafts "56, 51 (Fig. 2) and 58. (Fig. 6) and pairs of bevel gears 60, 6! and 62, to, a jack-shaft 63 "inter- 'mittently rotated by mechanism which may be of f the Geneva-stop type, or some such like mecha-.

nism. However, in the present instance I employ a discontinuous gear 64' (Fig. 12) mounted on the main shaft 46 for co-operation with a pinion'85 provided with a stop 66 having a depression'for co-aCtion with a land 6! on the'gear 64, the man-.

ner of engagement being such that the'depressionwill receivethe land as the pinion is disengaged from the'toothed portion of the gear. This construction transmits rotation to the shaft 31 in synchronism with the reciprocation of the pressure-slide 42, the shaft 31being rotated during a portion of the rotation of the shaft'46, while the land 51 is within the stop-depression during the other portion of the rotation of'the. shaft. I pre-.

fer that the shaft 31 be rotated during that portion of the cycle at which the slide 42 is at its most elevatedposition, while the roll 44 is riding on the rest-portion b of the cam 45; Preferably, the shaft 31'is locked against rotation before the rest portion of the cam leaves the roll.

The main shaft 46 may be extended forwardly from under'the bed-plate 20 (Fig. 2) for connection, with the glue-applying mechanism G, supported upon the machine-frame in a location a convenient to the operator. This applying mechanism is illustrated in detail in Figs. 21 and 22.

It preferably includes a glue-well or receptacle 68 I having rotatable therein a feed-roll 69 connected at one end by worm-gearing!!! with the main shaft 4 6, and at its other end by spur-gearing 1| with the shaft of a brush '2 rotatable upon the receptacle B8. The brush "I2 is preferably formed of circumferentially spaced longitudinal rows of bristles or fibers 13. The central por-.,

tion of the ends of the fibers of each row is raised or bulged at 14 outwardly from the end portions, being approximately complementary to the hollow of the cup of the heel 9. 'I'he'opposite ends of the portion 14 will come within the width of the narrowest heel to be operated upon by the machine, while its projection outside the adjacent end portions is greater than the depth of the largest heel-cup. The cross-sectional area of the portion 14, considered radially, is approximately equivalent to the corresponding area of the largest cup to be coated. The brush12 is so partially rotated for each turnof the shaft48 that successive rows of fibers 13 are presented above a cover-plate 15 upon the receptacle 68.

The longitudinal peripheral contour of the'roll 69 is generally complementary to the corresponding contour of the brush, and hence on such partial revolution a film of glue will be laid on the ends of the bristles of the successive rows thereof. To regulate the thickness of thisfilm of glue, I provide a scraper-bar, 16 pivotally mounted in the receptacle 68 foriadjustment of its edge toward or from the periphery .of the roll 69. This bar has an arm 11 (Fig. 22) engaged by a thumbscrew 18 for movement of the scraper-edge toward the roll 69, while a spring 19 retracts the bar on reverse movement of "the thumb-screw.

Connected with the continuously revolving,

counter-shaft 52 by bevel-gearing 80 is a flexible driving cable 8| enclosed in a flexible,cable housing 82 (Fig. 6). A U=shaped frame 82' swings on the counter-shaft 52 for supporting the adjacent end of the housing 82, the other end of which is attached to one end of the poweroperated finishing mechanism H (Fig. 25). This :preferably includes a pair of axially alined, spaced, tubular'handle's 83, 83, in which is journaled a shaft 84, having one end connected to the driving cable 8|. Mounted on-the'shaft 84 between the inner ends of the handles 83 is a cylindrical finishing member 85, which may comprise a grinding medium, as an emery-wheel or the like, or the finishing may be done by means of a rotary cutter, as a filel' The contour of the cutting periphery of the file may be of a shape conforming to the purpose in hand, a cylindrical portion 85 and a curved or bulbous portion 85 A flap-press K, adapted for co-operation with the heel-set A to firmly press the flap 8*! of the sole of the shoe 8 againstthe breast 9 of the heel 9 during the drying of the adhesive employed, is illustrated in Figs. 1,5, 23, and 24'. This press includes an inverted U-shaped Y body or shackle member 86 formed to embrace the instep of the shoe 8. The end of each leg of the member 86 is formed with .a hook 81 engaging one of the shoulders 2, 2, on the member I of the heelset. The bight of the shackle 86 is preferably flattened and has medially threaded therethrough a thumb-screw 8-9, from the inner end of which is supported by a ball-and-socket or other universal joint 89 a pressure-plate 99. Secured to the plate is a resilient or yielding flap-engaging head 9|, which'I prefer to so form of spongerubber that it will fit upon the instep and against the heel, as shown in Fig. 15. Guide- pins 92, 92, upstanding from the plate 90, freely slide through apertures provided in the bight of the member St in order that the head 9| may be approximately alined with its intended position on the shoeassembly B when the flap-press K is hooked to the heel-set A.

In Figs. 19 and 20, I show one form of an unlatching device L for disengaging the heel-set A from the shoe-assembly B. This preferably comprises a pair of spaced, upstanding, plate-engaging, tubular members 93, 93, rigidly mounted on a base 94, for the reception of the legs of the Ushaped member I of the heel-set. Rotatable upon the base 95 between the members 93, and adapted for registration with the head of the wedge member 6 of the heel-set, when the latter is disposed upon the device L with the plate member 3 resting on the upper ends of the members 93 and the legs of the member I received therein, is a ratchet-wrench-socket 95. The socket is provided with a ratchet-handle 96, co operating with a ratchet 91 on the socket member 95. When the shoe-assembly heel-set unit A--BC is mounted in upright position on the device L, the operator may, by simply rotating the socket 95 by the handle, so loosen the Wedge member 6 that the latches 5, 5, may easily be carried out of retaining engagement with the member I, and the latter shifted upwardly with respect to the plate 3 to permit removal of the shoe.

In Figs. 26 and 27 is shown one form of a poweractuated trimmer or cutting mechanism M which I prefer to employ for removing the overhanging part of the flap 8 after gluing said flap on the heel 9. On a frame 98, which may conveniently be a bench, is journale-d a guide wheel 99 for contact with the side of the heel at the breast-edges. The wheel has a portion I90, of reduced diameter, the upper surface of which furnishes means for lifting and feeding the margin of the flap to the cutter. A motor IIll carries upon an extension IEII of its shaft a cutter or saw-like member I92, the cutting edge of which extends below the upper face of the wheel portion I00. I prefer to operate the cutter I92 tangentially to the wall I99, so the shaft lflI lies diametrically of the wheel 99, and a guard I93 is provided, supported from the motor, for enclosing the cutter,

In Figs. 28 and 29 is shown another form of power-trimmer M, including a motor I9 I shaftextension lfil and circular edge-cutter I92f. A platen I96 may be mounted on the frame 98 adjacent to the trimmer M, before described. The cutter I92 projects through a slot I635 in the platen. A guide I96 is adjustably mounted on the platen for movement toward or away from the cutter I92. I prefer to employ this trimmer Mf for cutting oh the end of the flap 8 the tread of the heel 9 engaging the guide I06 during the operation. v

In practice I prefer to combine the shoe-'rest D,

clamping=head E, pressure mechanism F, glue applying mechanism G, and finishing. mechanism H, in one machine,- and to mount the unlatching means L and the power trimmers M and M on a bench, which may or may not, 'as desired, form an extensionof the bed-plate of the maehine,

The first step in preparation-for the operation attaching a heel to a shoe consists preferably mounting the unlatched heel-set A in the ma chine. For this purpose, the operator with one hand grasps the handle 34*, and swings the fingers to one siee, While with his other hand he moves the plate 3 of the heel-set to the e'iid of the U- shaped me-miner I, and inserts the enlargements 3, of said plate ihte the C=shaped members 34, 3Q 9f the head E, with the seeker, member 32 engaging the wedge member 6. The handle -34 is then released, allowing fingers 33 to return to plate-supparting position; whereby the heelset A is suspendedfrom the head E and so held, without further attention frem the operator, as to leave ample clearance between the mate 3 and the shoe r'est D te receive the shoe-assem bly B.

The next step is t6 apply the glue to the heel. This operation has heretofore been one requiring considerable skill on the part of the operator, be cause the glue should be evenly applied over the cup of the heel and yet none allowed to escape around the edges of the cup to mar the appearance of the finished shoe. Furthermore, just enough glue for the purpose should be used, because-if there is too mucn'tne surplus will be squeezed out from'under the edges of the heel cup, while if the amount of glue used is deficient, the adhesion of the heel to the shoe is impaired. I overcome these difficulties by reason ef the bulged portion 1 3 of the longitudinal peripheral contour of the rows of bristles, 13, on the brush H of the gluing mechanism G; By reference'to Fig. 21, it will be seen that the ends of the bristles along the cylindrical portions of the brush 12 are but a slight distance abeve the plate 15. Hence, the operator has only to grasp a heel irlinverted position and move it across the plate I5 so that the cup of the heel will receive the brush-portion M, to quickly and aeciirately apply the glue to the surface of the-cup; Because the brush at 14 is narrower than the smallest heel, there are nobr'is'tles projecting sumeienu above the plate to cause any glue to adhere to the sides of the hee while at the same time, since the height of the enlargementat I4 is greater than the depth of the largest heel-C ub, the tendency of the bristies is to swing outwardly more or less radially to the face of the c'i-ip, and deposit their carried film of glue enemy tner'edvi. The thickness of this film is regulatedby the s'lape'r bar I6, and a fresh row of bristles thus acted upon is resented above the iii-ate 15 once during each cycle of the operations. -Wh-ile the operator is apply ing the glue to the heel with one hand, with his other hand l-ie helds a shc'ie assembly B in an in verte'cl position,- with fine-bottom in View, and then laces the glued nee] on' the neel seat, holding the breast-edge against the shoulder II of the shoe. Holding the shee and-heel-assembly with both hands, the operator slips it into the heel-set A, with the cone or the last between the guide fingers 23 of the shoe-rest D and the hole'lfl over the pin- 24. This s'iifiicie'ntly alifies the shoeassembly in the machine and may be acom plished with great facility. 1

Still holding the heel in' place on the shoe assembly B, the perator depresses the pedal 29 heel on the heel-seat of the shoe inthe location to clamp said assembly betweenthe head'E and 3, the latter being held by the headE acting as an abutment for the'pressure mechanism F. As

the member I rises, its bight enters into the groove.

ll iin the cone of the last (Fig. 18), while the latter fits between the shoulders 2, 2 (Fig. 17).

The assembly B;is thus positioned by the heelset and yieldingly compressed between the bight of the member I and the heel-pressing fixture C.

the latter freely swinging on the plate 3 until the bridge-piece I2 finds its seat on the heel. It, ,will be seen from an inspection of Fig. 15, that,

on lifting action .of the slide 42, the fixture C distributes the pressure to the heel on both sides of the line of action of the heel-set A', thereby holding. the heel uniformly on the shoe. "This acts automatically to evenly seatthe cup of the determined by the operator, the line of resultant pressure passing through the forward halfv of the heel-seat of the shoe. When the roller 44 has received contact of the rest-portion b of the cam 45, the pressing action is completed, and the shaft 31 is rotated to latch the plate 3 in its shifted position on the legs of the member I, thereby attaching the heel-set and its carried heel-contact member C on the shoe-assembly to securely hold the heel on the shoe. When thuspressed against thelheel, the member C may rock and shift bodily upon theseat 'IB'and bend to adjust itself to the surfaces with which its ends contact. The sev eralparts are now in the positions shown in Fig.

17.. Upontermination of rotation of the pinion 65, thestoptfi co-operates with the looking land 61 onthe gear 64, while the roller 44 contacts with the falling portion 0 of the cam 45, thus permitting the slide 42 to be retracted by the spring Thefshoe-assembly B is now positioned in the machine between the head'E and the rest D, the heel 9 being held under pressure on the shoe 8 between the fixture C and the shackle member '.I of the heel-set A. The breast 9 of the heel and :the sole of the shoe are in full vision of the operator, who now takes in each hand a handle 83 of the mechanism H, and passes the finishing member 85 over the heel-breast to smooth it' preparatory to gluing the flap 8 thereupon. This 'being' accomplished, the operatorapplies adhesive to the heel-breast, and with his fingers stretches and smoothes the'fiap thereon. Then taking the flap -press K with the head 9I fully retracted, the operator hooks the shackle 86 under the shoulders}, 2, of the heel-set, and turns the thumb-screw 88 to so forcethe head against the flap that'uniform pressure is appliedto said fiap over the instep of the shoe and the 'breastof'the heel (Fig. 15) The pedal 29 being released, the head E is raised by the spring 28 to its normal position and disengages the -big ht' of the shackle member I from the rest. D. *This: permitsthe heel-set-shoe-assembly audits heel-pressing means C and flap-press K may be removed from the shoe-assembly B,

'For this purpose, the operator mounts the assembly AC-.-K B in an inverted position in the unlatching mechanism ,L, with the legs 'of the shackle I engaging the'tubularmembers 93,

and the head of the wedge member 6 within the socket member .95. A turn of the ratchet-handle the heel, the overhanging parts of the flap are trimmed flush with the sides of the heel-breast, as suggested by the dotted lines III! in Fig. 30,

96 will loosen the plate 3 from the shackle, thus and the end of the flap is preferably trimmed short of the tread of the heel, or aboutv where the lift and the heel proper are joined, as indicated by the dot-dash line I98 in Fig. 30. As

best seen in Fig. 26, one side of the heel 9 is brought against the periphery of thewheel 99,

the latter having thus a rolling contact with the heel. The untrimmed side margin of the flap then lays on the portion I09 across the plane of operation of the cutter I02. It is therefore lifted and fed to the cutter for severing the overhanging margin of the fiap 8" along a line defined by the side of the heel, as the latter is moved by the operator. Having'trimmed the sides of the fiap, the operator moves the shoe to the trimmer M and places the tread-of the heel against the guide IE6 of said trimmer. He then slides the heel over the guide, to cause the cutter a I82 to sever the end margin. of the flap along the line I91 to a width predetermined by thesetting of the guide. This completes the operation of mounting and finishing the heel .on the shoe. 7
