HEEL-CODIPBESSING MACHINE.

Application filed January 31, 1920. Serial No. 355,330.

1 0 (4H whom it may concern Be it known that l, ERAsTUs E. .VINKLnY, a citizen of the United States, residing at Lynn, in the county of Essex and State of lifassachusetts, have invented certain improvements in Heel-Compressing Machines,

of which the following description, in conthe heels of boots and shoes by subjecting them to a heavy condensingpressure between a set of dies or formswhich act againstthe sides and around the contour surface of the heels, and other opposing compression members which act upon the heel seat and tread surfaces of the heels. A machine ofthis general character is shown'and described in the United States patent to Charles L. Allen No. T76,823, and such machines have gone into extensive use and have been commercially successful. In machines of this general type it has been the common practice to provide opposed compression members to act iieightwise of the heel and to support one of these members in a fixed position, the other member being movable towards and from the fixed member. Likewise in this general character of heel compressing machines, the side dies or confipression members have been caused to move inward towards the heel and engage the sides and contour portions of the heel due to the movement of approach of he compression members which act heightv of the heel. 'lhe ed'ect of this has been ti at the side dies or compression members would engage the heel as they more in direction of approach before the heel was placed under heightwise compression, and this mode of operation has been highly successful in machines for compressing heels of ordinary types. I

In treating certain forms of what may b termed freak heels such, for instance as Louis heels or those having a very pronounced wedge shape or formation, such as commonly seen on ladies" shoes, it is not sufficient alone to change the shape of the com". pression members in orderto subject the heel to the desired condensing pressure. In Louis heels, for instance, the smallestdimension of the heel is at a point between the tread and heel seat surface; that is, the smallest cross sectional area of the heel is at a point between the top and bottom of the heel, and the heel. expands both upwardly and downwardly from this point which may be regardedas the datum plane of the heel. Toefl'ect proper. compression of such form of heel, the heel seat and tread. surfaces should be compressed towards the datum plane and the compression movement of the portionof the heel at opposite sides of the'datum plane should be proportional tothe distance of thesurface of the heel from the datum plane.

l in-important feature of the present invention, therefore, consists of opposed compression members for acting upon the heel seat and vtread surfaces which are given cornpressing movements of different amounts towards each other or the datum plane of the heel. In carrying this feature of the invention into practical effect the opposed com-. pression members :for acting upon the heel seat and tread surfaces are preferably given compressing movements towards the datum plane of the heel in amounts.proportional to the distance of the heelrseat and tread surfaces from the datum plane, the effect being that the datum plane of theheel itself remains substantially immovable while the top andhottom portions of the heel are condensed towards the datum plane. \Vhere the heels to be compressed are of pronounced Wedge shape, such, for instance, as are observable on ladies shoes, if the side compression members should act upon the side contour portion of the heel prior to'the action of the opposed heel seat and tread surface compression members, the heel itself is liableyto be misplaced or disturbed as the side members come together and bear upon its side contour surfaces. Should this occur,the opposed compression members for acting upon the heel seat and tread surfaces are called upon to return the heel to its proper position between the dies or' forms during the compressing action, with the result that the heel is liable to be*injured, ,especially along the edge portions of the heel lifts. In the case of Louis heels where the datum plane or narrowest part of the heel is between the top and bottom of the heel, should the side dies engage and bear upon the side contour portions'of the heel prior to the engagement of the heightwise compression members with the heel seat and tread surfaces of the heel, the lifts of the heel in the zone adjacent the datum surface are liable to be separated or opened up to some extent with resultant unsatisfactory product.

' A further important feature of the present invention, therefore, consists in giving to the opposed compression members which act upon the top and bottom ofthe heel and the opposed compression members which act on the sides of the heel, simultaneous rectilinear compressing movement, so that the heel will be acted upon both vertically and horizontally during the same period of time or coincidenta lly. In carrying this feature 'of the invention intopractical effect, the opposed compression members for acting upon the top and bottom of the heel and the opposed compression members for acting upon the sides ofthe heel, may all be given their compression movements'to simultaneously engage and compress the heel, so that the heel Will not be disturbed in its position as the.

compression members. act upon it, and the lifts of the heel'at opposite sides of the datum plane-of a Louis heel will not be opened up or separated. I i I A further important feature of the invention consists in compression members ha ing the above described characteristics in combination with a breast plate which acts to compress the heelin a longitudinal direction simultaneously with its heightwise and sidewise compression. I l

Inasmuch as the opposed compression members which act upon the heel seat and tread surfaces of the heel are each given compressing movements, the heel to be compressed must be. presented in position between the compression members and held there independently of the compression members until they take charge of the heel.

Another important feature of the present invention therefore consists of a heel seat die and an opposed tread plate mounted upon separate heads independent of'the compression members and movedtowards each other to engage the heel seat and tread surface of a heel between then: and then movable to present themselves and the heel between the compression members. This feature of the invention is embodied in opposed heads adjacent to the compression members and slides mounted on the respectiveheads and carrying the heel seat die and tread plate respectively. To enable the heel seat die and'tread plate to move towards each other during the action of the-compression any suitable number.

members upon the top and bottom of the heel, the heads which carry the heel seat die and tread plate, are yieldingly mounted' The present invention further contemplates the automatic presentation of the uncompressed heels to the compression members and the return of the compressed heels to a carrierwhich transports the compressed heels to a discharging station. An impor tant feature of the present invention in this respect, therefore, consists of a carrier for presenting uncompressed heels between the heel seat die and tread plate and means for actuating the latter toplace themselves amt the heel between the compression members and return the compressed heel to the-can rier.

The machine frame for supporting the various parts-may be of appropriate char-- acter and in present instance it comprises the side frames 1. suitably held in associated relation by tie members 2, which might be formed either separately from. or'integral with the side members. The main support ing frame is surmounted by a removable eas-' frame and held hbv aseries of I ing 3 which tied to the m in rigid association therewii. I tie bolts 4t, three of which are shown in the present instance but of which there may be The tie bolts 4; are anchored to the main frame at their lower end portions by pins or wedges 5, Figs. 1 and 4;, and serve to hold the frame 3 in rigid association withthe main frame by means'of the pins or wedges 6, Figs. 1 and 4;. The tie bolts throughsuitable lugs on the mam frame and casing 23, the frame construction being such that the main portions of the operating covered.

Mounted in suitable bearings 7 formed in the side frame is the main'drive shaft 8 carrying the fast and loose pulleys 9 and 10. The drive shaft 8 may be driven from any suitable source of power, as by belting from a line shaft in connect on with the pulleys 9 and fl), and if desired, means may be provided for shifting the belt from the fast to the loose pulleys, or vice versa. The drive shaft 8 at its end opposite the fast and loose p ulleys 9 and 10, is provided with a fly wheel 11 by which smooth running of the machine is effected.

The drive shaft 8 has mounted thereon the gear 12, 1 and l, which, through a train of mechanism, as will presently be described, transmits operating motion to the various machine parts. This train of mechanism may be variously contrived, but in the present instance consists of a pinion 13 mounted on a shaft 1a, Fig. 1, which is supported in suitable hearings in the machine frame and has on its outer end a. toothed wheel or gear 15. Figs. 1 and 4:, which is in operative engagement with a large pinion 16 mounted upon the end of the cam shaft 17, the construction being such that upon rotation of the drive shaft 8, proper rotative movement will be imparted or transmitted to the cam shaft 17. The cam shaft 1'7 is mounted in suitable bearings 18 on the machine frame and has fastened thereto the bevel gears 19 which engage correspondingly beveled gears 20 secured to the vertical shafts 21. The verticalshafts 21 are substantially alike in all respects and are mounted in suitable bearings 22, Figs. 2 and l. lrl ounted in the hangers 23. carried by the casing is the shaft The upper end portions of the shafts 21 carry bevel gears 26 which engage correspondingly beveled gears 27 secured to the shaft 2-il, the construction being such thatupon rotation of the drive shaft rotary move! ment will be imparted to the shaft 17 and also to the shaft 245 The bevel gears 1.9, 20,

26 and 27 may be secured to their respective sh afts in any appropriate manner, but as indicated in the drawings they are preferably pinned totheir shafts.

7 Each of the shafts '117 and 24; is utilized to give compressing movements to the compressing members which act upon the top and the bottom of the heel. These compress inp; movements of the compressing members are simultaneous, but when treating freak heels such. for instance, as the Louis heel,

the conuiressing' movements of these com-' pressing members will be dlfferential, that is.

the compressing movement of" one will be greater or less-than the compressing move ment of the other. I

parts may be properly encasedor In the present instance of the invention,

the shaft 17 has secured thereto the eccensired to be given to the connected compression member. The shaft 2l has liken lee sc cured thereto the eccentric 29, the "eccentricity of which is proportional to the extent of compressing movement desired to beimpart ed to the associated compression member. When compressing r nquis heels, such, for in-' stance, as that indicated in Fig.0, diiferen tialmovements are given to the compression members actuated by the eccentrics 2S and 29, in order to impart proportional compression to the upper and lower portionof the heel oniopposite sides of the datum plane,

The Louis heel a, Fig. 9, it will be noted, has its smallest dimension at a point between the heel seat and tread surfaces whicln'in the present instance, is indicated by the line 2'), and whichfor the purpo's'e'of illustration may be assumed to be one-third of the height of the heel from the tread surface 0 and two thirds of the height of the heel from the heel scat surface cl. Under these assumed conditions the'compressing movements of'the up per and lower compression members should be directly proportional to the distance of the heel seat (Z and tread surface 0 from'the.

datum plane 6, that is, the. compressing action of the lower compression member would be one-thlrd and that of the uppercompres sion member would he two-thirds, eachdire-cted towards the datum line b. This differential or proportional movement of the upper and lower compression members be readily effected by appropriate ,change in the eccentricity of the eccentrics 28 and 29 which give movement to theco-i'npression' members. as will now be pointed out."

Suitably secured to themachine frameis the plate or bracket 30. In the'present instance this is indicated as secured to the ma chine frame by a series ofboltsSl-at its upper end and its lower end is formed integral with or secured to thelcross plate 32, Fig. l.

Mounted on the face of the plate 30 are the.

guideways' 33 for the upper and lower'co'm- Dression members 34: and 35, respectively, The guide-Ways for the upper and lower,

compression members may be'variously con trived but, asindicated in the enlarged view, 5. 7 and. 8, the guides 33 are of general box formation. to receive the sliding compression members 34.; and 85 which act upon the top and bottom of the heel. 'The upper compression member 34 is connected. to a link or rod 36by a pin 37 -and the enlarged boss on the lower end of the rod or link 36 bears in a correspond. up; recess in the coinpression member sane construction being such that while the compression member34k enlarged hearing. portion 38 between the rod pinned to the link or" red 36. as at 37, the i y ,130

The links or rodsSG and 39 f 1 the upper and lower comed to the eccentrics 29 and 28 by suitable straps a0 and 41-, the-construction being such pressioninembers will be moved towards and from each other and the extent of this movementwill be, determined by the eccentricity oftheir respective operating eccentrics.

ZIHEBHElJQIS for acting upon the sides and contour surfaces of the heel,- are best ill-strated in simultaneously to compress the heel between them. Y

The side compression members 4-3 are con nected tothe arms l i, Figs. 2 and l, which are themselves connected to the'eccentrics 45., respectively, upon the shafts QLand, since the movements of the side compression members Z are. to be of l ke extent. the eccenofthe. cams .45, which actuateithe side compression" niembers; is the The 11 me lbGlL'S bya pin and the en} la *gedhub port on of-the arm acent the pin may bear upon a correspondi. gly. socketed portion of the slide to afford an abut inent against which'the'hub portion may during; the en reine compress-ion im- V I 1 i parted by the-sine in rnbers.

The slide 56 carries the breast plate 58, Figs. 2, through the meansdescribed, is caused to bear upon and press against the breast of the heel when the latter is under the com pressing action of the compression members herelnbefore described. The gear 51,

Figs. EZ and 3, is connected to a gear orpinion 59 Which derlves its rotary-movement,

to actuate the breast plate through a train of gear ng connected with one of the shafts its opposite end. at with aslide56, guided. for movement towards and from the heel.

5, 6,7 and 8, which,

in the present instance, as indicated in" ig. 2, the shaft Ellis provided with a gear 60 which, through an idler 51., transmits rotary movement to the gear59.

The present invention contemplates that machine. A. novel character. of feeding means for the above purposes will now be explained.

Loosely mounted isthe carrier or feed table-62 which is pro-, vided at intervals'with pairs 65 and caused tomove in unison upon their pivots by a suitable connection, such as the pin and "the uncompressed heelsv shall be automatisi cally presented to the compression members and that the compressed heels shall be automatically removed from the compression members and finally discharged from the on the sleeve 50, 3,

of clamps 63 anc 6e pivotally connected to the table at" 100. socket. 66, Fig. 2. A spring 67 nor- H 'mally acts to hold the clamping end jaw portions 63 and 64:: of the clamps towards each ot 181 and in posit on toholdla heel.

Extending upwardly from the machine frame is an arm 68 the top portion of which affords a rest {'39. for a heel which the work;

man is. to place between the clamps 63 and when they reach receiving position. The rest 69 is preferably provided with slide plate. 70 the inner end portion, 71 of which. is formed as a heel breast gage. The

slide plate 70 may be secured to the support adjustably by means of the slot and pmlWhen the clamping members 63 and 64econnections 72, 2.

are over the support 69, the workman shoves a heel, breast I it reaches the breast gage 71 and thereby locates a heel properly within the clamps.

or other preferred form of intermittently acting devices. of theinvention, the carrier 62 has a hub portion on which is mounted the plate 73, Figs. 2 and 3, having a series of slotted 7 which are adapted to be engaged at times by" a pin 7 5 carried by an arm76 se- In the present instance termittent movement and this is preferably effected by-a Geneva escapement mechanlsm cured for rotative-movement with the gear or pinion 59. also associated with the arm 76 and, perforce, with the gear or pinion 59, is the disk 77 having a cut-away portion 78, Fig. 2, the constructionbeing such that as the arm 76 carrying the pin is rotated it will engage one of the slotted arms 74 and turn the carrier or table 62 apart of a rotation, whereupon the peripheral portion of the disk 77 will engage the curved part 79 of the plate 73 and lock the carrier or table from accidental rotary movement.

Intermittent movement of the carrier or table 62 successively presents an uncompressed heel into position for transfer to the compression members, and the present invention contemplates that when in such position the uncompressed heel shall be engaged by its heel seat and tread surfaces and transported t position for the action of the compression members. Tothese ends the present invention provides a heel seat die and a tread plate mounted on opposite sides of the plane of movement of the carrier or table 62, and means are provided for causing the heel seat die and tread plate to move towards each other and graspthe heel by its heel seat and tread surfaces while under control of the carrier; Means are fun ther provided to cause the heel seat die and tread plate to detach the heel from the carrier and present themselves and the heel between the compression members and then return the compressed heel to the carrier. The means for giving to the heel seat die and tread plate the described movements to ef-' feet the purposes stated, are substantially alike and therefore a lescription of one will suffice for both. 1

Mounted on the machine frame or supported by a bracket secured thereto is the guide-way 80, ig. 1, in which is mounted for reciprocating movement the. hollow plunger 81 carrying at its lower end the head 82. In the hollow plunger81 is a spring 83, the lower end portion'of which bears upon the lower wall of the hollow plunger and the upper end portion of which bears against a block 8% connected by a pin 85 with an operating arm 86 secured to the rock shaft 8'? mounted on the machine frame. The hollow plunger-'81 is alsoprovided with a slot 88 whereby the plunger and its operating arm 86 may have limited independent movement. The row-r shaft 87 is actuated by an arm 89 connected to a link 90, the lower end of which connected at 91 to the arm 92 secured to the rock shaft 93. Extending from the rock shaft93 the arm' 9 1, the end of which carries a roll 95 which travels'in the cam groove 96 of a cam 97, Fig. 1, secured to the cam shaft 17, the construction being such that upon rotation. of the shaft 17 the plunger 81 will be reciprocated in its bearings. In order to reciprocate the corresponding lower plunger which, in the present instance, carries'the heel seat die,'the

rock shaft 95 has secured thereto vthe arm 98, Fig. 1, which is connected tothe lower plunger 99 and its head 100 in substantially the same manneras the arm .86 is connected to the upper plunger and head.

The upperhea-d 82 carries a slide 101, Figs. 1, 5, 7, and 8, having a slot 102 which engages the pins or blocks 108 projecting from the head 82 so that the slide 101 may move longitudinally to the right and left, Fig. 1, relative to the head and yet be mov able up and down with said head. The slide 101 c-arriesthe tread plate 104; The lower head 100 is similar to the upper head 82 and has connected to it the slide 105 which is slotted at 102 like the slide 101 and carries the heel seat die 106. From. the construction describedit will be apparent that upon movement of theupper and lower plungers towards each other, the heel seat die and tread plate will be caused to engage the top and bottom of a heel presented by the carrier 62.

In order to move the heel seat die, the tread plate, and heel into position between the compression members, the slides 10land 105- are peratively connected to suitable actuating mechanism. The actuating mechanisms for each oftheseslides is or may be the 'same, and a description of one will suf-'- fice for both. I,

Pivotally mounted on the machine frame at 107, Fig. 2, is a lever, the arm 108 of which carries at its end a pin 109 which extends through ano-pening in the slide 101. The pin 109 is elongated so thatwhile the slide 101 may move up and down with the head 82, the'pin 109 carried by the lever will remain inoperative engagement with the slide. The lever is actuated by an arm 110, Fig. 2, which carries a roll 111 traveling in the cam path 112 of a cam 113 mount-- ed on one of theupright shafts 21, the construction be ng such that upon rotation of the upright shaft the lever arm 108 will be. given appropriate movement to cause the slide 101 and the tread plate 10 1- to be moved relatively to the head 82. 105 is similarly associated with another lever arm of the same character, it follows that the two slides 101 and 105 will be moved together after they have grasped the reel seat and tread surfaces of a heel and will presentthemselves and the heel between the compression members. posed compression members act uponthe heel seat and tread surfaces to compress the heel through the independently mounted heel seat die and tread plate. After theheel is compressed, the .heel seat die and tread plate are returned to their initial position to thereby return thecompressed heel to the carrier. Inasmuch as the heel is clamped between the yieldingmembers 63 and 64:, the

Since the slide Thus the oppin, the wing portion 115 will click outer end portions of which are'outwardly inclined,the heel seat die and tread plate are enabled to remove an uncompressed heel from'the carrier and return a compressed heel to the carrier. v

The'carrier is given its intermittent movement in the direction indicated by the arrow, Fig. 2, and as the compressed heel approaches the loading position for another heel, theclamps are automatically opened to release the compressed heel. This is etiected, as indicated in Fig. 2, by means of a pin 11% against which a Wing portion 115,

extending from. one of the clamping members 63 and 64L, impinges as the carrier or table 62 moves the clamps into position for recei -Jing another heel. The pin 114: is preferably carried by the machine frame and in the present instance may be conveniently supported by the bracket arm 68, so that as the carrier 62 moves the clamps past the over the p n and the spring 67 will return them to their initial position for grasping another bottom of the heel.

heel inserted by the ing station. Y Y Y I While "the advantagesof the heelcompressing nachine'herein described are more conspicuously apparent with respect'to the t'reatmentof freak heels, such as those having extreme wedge shape, and those of the Louis type, certain features of the inven tion may be advantageously employed in attendant at the receivconnection with the compression of other forms of heels and shoe parts.
