HEEL -PRICKIE'G MACHINE.

Application filed September 4, 1915. Serial No. 49,013.

To all whom it may concern Be. it known that I, JOSEPH H. Porn, a citiwhich the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures. This invention relates to heel pricking machines by which perforations are formed in heels of boots and shoes for the reception of the attaching nails.

It has been found in practice that many classes of heels may be attached to boots and shoes by driving the attaching nails directly into and through the heels without first pricking them or providing perforations for the reception of the nails. In some classes of work, however, it is desirable or even necessary to prick the heels preliminarily to the nail attaching operation, especially where the heels are formed of dense material or of unusual height. If this is not done the nails are frequently bent or deflected from ,their proper course while being driven, as described in the patent to Glidden, No. 1,077 ,929, granted November 4:, 1913.

In thus preliminarily pricking the heel, the holes or perforations must be located on the tread surface of the heel with the rearmost.

hole or perforation at the same distance from the rear of the heel, irrespective of the size or shape of theheel itself, because in the heel attaching machine, the heel is positioned with relation to the rearmost attaching nail which should be the same distance from the rear of the heel, irrespective of the size or shape of the heel. When a heel thus positioned is being pricked by a series of awls and also when the heel is being stripped from the awls, the lifts of the heel are liable to be separated by the relative movement of the awls and lifts as the awls pass into and from the heel. Accordingly, animpo'rtant feature of the present invention consists in positively positioning a heel to be pricked so that the rearmost hole or perforation made therein shall be always at a predetermined distance from ,the .rear of the heel and holding the heel by positive pressure during the heel pricking or stripping operations.

Specificatiof of Letters Patent.

The relation between the tread surface and heel seat of heels varies. In some cases the tread surface may remain uniform and the heel seat may vary by reason of variation in the pitch of the heel, or both may vary in extent and angular relation of their respective surfaces. The present invention, accordingly, contemplates means for adjusting the heel seat support or follower block to different inclinations and difierent posi- 30118 lengthwise or longitudinally of the In the preferred form of the invention, as lllustrated herein, the awls pass through a stationary templet and enter the 'tread surface of the heel at an oblique angle thereto in order that the attaching nails to be subsequently driven may be inclined to the tread surface. Another feature of the invention, therefore, consists in mounting the awls upon an awl carrier block which as it moves the awls in their oblique path inclined to the tread face of the heel, is caused to be moved in a corresponding direction.

The heel positioning device is of novel construction and is positively moved to and from its operative relation with the heel to be pricked. It may happen at times that the operator may so adjust the fork of the heel positioning device that it will be'in the path of the awls in trying out the machine. This is more liable to occur when heels with small tread surfaces are to be pricked. To prevent injury to the awls or the fork in such cases, the .presentinvention contemplates a yielding connection between the fork and its carrier, which will permit the fork to yield when struck by the awls, but it is of a character to normally maintain the fork in normal relation to its carrier.

At times it is desirable to adjust the position of the awls and templet with relation to the heel to be pricked and to remove the awls and templet for the substitution of others suitable to the character of work to be done; To this end another feature of the invention consists of an adjustable support for bolding the templet andawl block or carrier and permitting ready removal thereof.

In the present invention the heel to be pricked is held by positive pressure between the stationary templet and follower block, and the awls are moved to prick the heel and are then withdrawn. In the preferred embodiment of the invention in these respects, the awls are actuated from a slide having a movement greater than that required to in sert and withdraw the awls, and to prevent the withdrawal movement of the .awls from disengaging them from the holes in the templet, a further feature of the invention-con- .sists in means for operatively disconnecting the awl carrier from the slide when the awls have been fully withdrawn from the heel and before they can be disengaged from the holes in the templet.

Various other features of the invention will be hereinafter described set forth in the claims.

In the drawings a Figure 1 is a perspective view of a heel pricking machine embodying the various features of the presentinvention;

Fig. 6 is a detail partly broken away, showin the yielding support for the heel;

Fig. is a perspective view with some of the parts shown in section, looking from the leftof Fig. 1 and with the heel pressure means omitted for clearness of illustration; Fig. 8 is'an enlarged detail showing the and definitely .40 means for operatively connecting and disconnecting the awl carrier to and from the slide; and

Fig. 9 is an enlarged detail showing the heel fork connection with its carrier. The bed or frame 1 of the machine is suitablyl supported as upon legs 2- and sustains the working parts. A main driving shaft 3 is L mounted in suitable hearings in the frame 1 and carries a belt pulley 4: and a pinion 5. A

hand Wheel 6 is also secured'to the shaft 3 for turning "the machine by hand when desired.

Operatively connected to the pinion 5 is a gear 7 secured to a crank shaft 8 suitably mounted in bearings upon .the machine frame. A slide 9 is mounted on suitable v guides or ways 10 extending longitudinally of the machine frame and retained thereonby the cap plates or gibs 11. Connecting the slide 9 with the crank 12 of the shaft 8 is the rod 13, the construction being such that upon rotation of the crank-shaft 8 the slide 9 will be reciprocated longitudinally of the machine frame.

When a heel is being pricked by the'awls and also as it is being pulled or stripped from the awls, the lifts are liable to be separated. This condition is liable to arise in pricking any form of heel held under yield ing pressure, but especially so where the heel isofunusual height or considerable pitch. To 70. prevent the occurrence of this objectionable condition, the present invention holds the heel by positive'pressure in the position to which it has been adjusted for the pricking operation. In the present instance, the heel is,positioned between a stationary templet and a follower block which is positively actuated to exert the desired pressure upon the heel, such actuation of the follower block being preferably obtained through toggle connectlons operated from the drivin shaft.

To this end there is mounted for movement longitudinally of the machine frame, the yoke 14 carrying a stem 15, to the end of which the follower is connected in a manner as will resently appear. Extending from the yoke 14 are the projections 16, preferably one at each'side, to which are pivoted the members 17 of toggles, the other members 18 of which are secured to a shaft 19 extending between the stationary supports such as the lugs 20. These lugs 20 may e appropriately secured to any convenient stationary portion of the machine, but in the illustrated form of the invention they are shown as projecting upwardly from the ca plates 11.

ecured to the shaft 19 between the toggles described, is the toggle-actuating cam 21 having a cam lower surface 22 adapted to be engaged by a roller 23 mounted upon the slide 9. The surface 22 of the toggleactuating cam is constructed and arranged to cooperate with the roller 23 on the slide v so that when the roller 23 is engaged with the forward or curved end portion of the actuating cam, as indicated in Fig. 3, the said cam will be moved to break the toggle;

but when the roller 23 is moved by its slide 9 toward the opposite portion of the cam 21, as indicated in Fig. 4, the toggle will be straightened.

The stem 15 is screw threaded, as indicated in vFig. 2, and is adjustable long1tud1-' nally of the yoke 14 by means of an ad ust ing nut 24, said stem 15 being retained from rotative movement by suitable means such as the key-Way and in 25, substantially as indicated in Fig. 2. ecured to the end portion of the stem 15 is the stem head 26, to which is adjustably connected the follower head 27 In the present'instance of the in-. vention, the follower head 27 is provided With a dove-tailed projection 28, as ind1 cated in Fig. 1, which engages a corresponding groove in the face of the stem head 26. The follower head may be connected to the stem head for adjustment in a direction lon- 'gitudinally of the heel by any suitable means, but in the present form of the invention, such adjusting means is shown as an adjusting screw .29, the end of which is screw threaded to the stem head 26, as indiengagement with the heel seat of a heel to be pricked. It may at times bexiesirable-to change the follower block for one of different contour, and to enable this to be readily done, the follower 32 is provided witha dove-tailed recess 34, Fig. 1, for, the reception of a dove-tailed projection on the rear portion of the follower block, the construction being such that the' follower block may be readily connected to and disconnected made in a series of heels may from the follower.

In order to adapt the follower block to the heel seats of heels of different pitch, the follower. 32 is adjustably mounted upon its pivotal connection with the follower head so that it may be turned about such pivotal mounting into different inclinations and then securely held. As a preferred form of means for thus adjusting the inclination of the follower, there is threaded into the follower head above and below the pivot 31 of the follower, the adjusting screws 35, the ends of which bear upon the rearface of the follower 32, the construction being such that by adjustment of the screws 35, the follower may be turned to any desired inclination suited to the heel seat of the heel to be pricked and be held securely in such adjusted position.

Heels vary greatly in size and shape. In some cases the treadfa'ces of a series of heels may remain uniform in size, while the heel seat may vary according to the pitch of the heel. Also, it may be that the erforations e varied in position and inclination. In these various conditions it is desirable that the heel seat of the heels be supported opposite the force exerted by the awls. This is efl'ected in the present invention by the described adjust- .ment of thefollower and the,follower head.

As hereinbefore noted, one feature of the present invention contemplates exerting up on the heel a positive pressure during the heel pricking and heel stripping operations, and that to this end the heel to be treated is held between a stationary templet and movable followen, It is desirable, however, that the templet as well as the awl-block be removarm 30 formed as part of or seably and adjustably held in their operative relation to the other parts.

' In the present instance ofthe invention,

the machine frame 1 is provided with upwardly-pro ecting side plates or flanges 36 which are provided with guideways 37, Fig.

7, for the reception of the templet 38 which is adapt-ed to slide freely in such guideways. In order to readily lift the templet from the guideways 37, a suitable handle 39 may be connected to the upper portion of the templet as indicated in Fig. 7. Since the templet is to sustain the positive pressure exerted upon the heel by the follower, the side plates 36 are preferably braced by the flanges 40, Fig. 7. i

Extending through a suitable opening in one of the side plates 36 is a templet support which, in the present instance of the invention, comprises an arm 41, the lower end 42 of which is turned toward the templet and is adapted to engage the lower end portion thereof, as indicated in Fig. 7. In-or- 'der that the arm 41 may be adjustably mounted upon its supporting side arm 36, it

is provided at its upper portion with asleeve 43, through which passes an adjusting screw 44having the thumb head 45,.the lower end of this adjusting screw resting loosely upon the top surface of its side supporting flange 36, substantially as indicated in Fig. 7. From the construction described, it will be apparent that the templet 38-, while fix edly held in the side flanges 36 to withstand the positive pressure exerted upon the heel during the pricking and stripping operations, is, nevertheless, readily adjustable in a direction longitudinally of the heel and likewise readily removable from operative position.

The templet 38 is provided with a series of holes for the guidance of the awls which are themselves carried by an awl block 46 adapted to be received in suitable guideways 47 of .an awl block carrier 48 mounted for movement longitudinally of the machine,

substantially as indicated in Fig. 7. The

awl block carrier 48 may be connected to the machine frame for such longitudinal movement by the guideways 49 on which rest the flanges 50 of .the awl block carrier.

The awl block carrier is prevented from rising from its guideways by suitable means such as the plate 51 secured to theunder portion of the awl blockcarrier and engaging a suitable groove in the frame 1 of the machine. 3

Secured to the templet. 38 are the guide pins 52, Figs. 2 and 7. These guide pins extend toward the awl block 46 which is provided with perforations 53, Fig. 7, to receive such guide pins. The guide pins 52 are parallel with the awls, the construction being such that as the awls are moved to prick the heel, as will presently appear, the

and awls will be moved in awl block will be moved in a path parallel with the awls; and by changing the inclination of the awls and guide pins 52, the perforations made in the heel may be varied, as desired.

The W1 block carrier s is provided with struction being such that by proper adjustment of 'the'nut' 57 the awl block carrier their pricking stroke by the slide as the latter moves to the right, Fig. 2; and since heelsvary in height, the desired length of prickling stroke may be imparted to the awls by proper adjustment of the nut 57.

The machine of the present invention is adapted for pricking heels, the heights of which may vary between wide limits, but it is desirable that in the retracting movement of the awls they shall not be withdrawn from engagement with the guide openings in the templet, and in this respect the present invention provides.means'- for operatively connecting and disconnecting the awl block carrier with its actuating means or slide so the templet.

that, regardless of the height of the heel, the awls on their. retracting stroke will not be withdrawn from the guide openings in- Mounted upon the slide 9 are .the pawls 60, preferably one at each side of the slide below the awl block carrier. These awls are normally under the influence of springs 61 tending to turn the pawls upwardly about their pivotal axis 62 to engage the ends of the pawls in notches 63 formed in the bottom portions of the'awl block. carrier 48, the construction being such that upon movement of. the slide the pawls 60 will engage the notches 63 in the awl block carrier and cause said-carrier to moveto the left and withdraw the awls from the heel, or strip the heel, as it is termed.

-' In order that the machine may be adaptedto prick the heels of maximum height as well .as those of height, it is essential that the slide-9 which gives the awls their pricking movement shall be moved an amount requlred by the maximum height,

of heel, regardless ofjwhether the awls are for the time being pricking a low orzhigh' wheel. When pricking a low heel, however,

if the retracting movement of the'awls con-- tinued to' be the same as when pr'icking'a high heel,ithe awls would be liable to bewithdrawn from their guide holes in the templet.

To overcome this objectionable condition, the present invention contem-- plates operatively disconnecting the slide from the awl block carrier whensaid car- 9 to the left, Fig. 2,

ried th'e awl block carrier' a sufficient distance to withdrawthe awls from the heel,

but before said awls are withdrawn from the templet. From the construction described it will be apparent that when shal low or low heels are being pricked, the nut 57 Will be adjusted on the rod 56 toward the awl block, and consequently the awls will not be forced into the heel until the slide 9 has moved a greater distance than it would have moved had the nut 57 been adjusted farther from the awl block. And conversely, on the reverse movement of'the slide the pawls 60 will pick up the awl block carrier and start the withdrawal movement of the awls at a later period than if a higher heel were being pricked. In order -to prevent the awlsLbeing withdrawn from the awl block under any conditions of. use, as by friction of the slide 9 acting upon the rod- 56, an adjusting stop 66 is preferably provided" to be engaged by the awl block carrier 48 when said awl block carrier has been moved a distance sufiicient to withdraw the awls from-the heel and before said .awls are withdrawn from the templet. This wherein it is indicated as a screw threaded into an arm 67" projecting upwardly from the bed of the machine.

From the construction thus far described,

dicated by dotted lines in Fig. 3 between the templet and the follower block, and the crank shaft 8 of the machine be then turned, theflslide 9 will be moved to the right, Fig. 2, and the roll 23 acting upon the toggle cam 21 Will cause said toggle to be straightened,

105 it will be noted that if a heel be placed as in-- 115 Upon further rotative movement of theQcrankafter they have been thus withdrawn, such. operative connection between the slide and awl block carrier will be interrupted. During all this time, that .is, during the awl pricking and withdrawing movement, the heel has been subjected to a positive pressure between the templet and the follower block;

but as soon as the awls have been withdrawn from the work, the roll 23 on the slide engages the appropriate cam surface on the toggle-actuating cam and breaks the toggle, thus returning the parts to the position indicated, as in Fig. 3.

In order that the heel may be property positioned in the machine for attaching the heels to shoes, wherein the heels are positioned with respect to the rearmost attaching nail, which is placed at-the same distance at the rear of the heel regardless of the. size or shape of the heel, the present invention contemplates means for positively positioning the heel blank to be pricked, so

that the rearmost hole or perforation formed 1n the heel will be in proper position to receive the rearmost nail in the heel attaching position.

As one means to this end, the side plates or flanges 36 hereinbefore described, have rising therefrom the arms 67, Figs. 5 and 7,

said arms being suitably provided with guideways for the reception of the heel positioning slide 68, Fig. 5. Adjustably mounted in the heel positioning slide 68,- is the fork carrier 69. tween the fork carrier 69 and the slide 68 may be effected in various ways, but in the present instance of the invention it is formed by an adjusting screw 70 suitably threaded into a projection 71 on the slide 68 and relatively mounted in a lug 72 mounted on the fork carrier 69, substantially as indicated in Fig. 5, the construction being such that by hand manipulation of the hand piece 73 secured to the adjusting screw 70, the fork carrier 69 may be moved longitudinally to different positions relative to the slide 68.

Mounted at the lower end of the fork carrier 69 is the fork for engaging the rear or curved surface of the heel adjacent the face of the templet. In the present instance of the invention the fork 74 is connected to its carrier 69 in a yielding manner topermit the fork to yield away from the face of the templet, should it be struck by the awls. As

one means to this end the fork 74 is mounted upon the fork carrier 69 pivotally, as by the pivot stud 75, Fig. 9, and said fork 74 is normally held in operative position in prolongation of the carrier 69 by means of a spring 76, one portion of which is secured to the slide 69 at 77, and the other end portion of which, as at 78, bears upon a portion of the fork 74, the construction being such that the fork 74 may be moved about its pivotal connection 75 with' the carrier 69 The adjustable connection .be-

E'il

when struck by the awls as they pass through the templet without causing breakage either of the awls or the fork, and upon retraction of, the awls, the construction is such that the spring 7 6 will return the fork to its normal operative position.

It is desirable at times to adjust the position of the fork 74 laterally of the carrier 69, and to ,this end the fork 74 is preferably mounted upon a plate 79 which is itself pivotally connected by the pivot stud 75 to the carrier 69. The fork 74 may be connected to the plate 79 by means of a screw 80, which, when loosened, will permit the fork to be moved laterally of the plate 79. Any convenient means may be employed to thus laterally move the fork 74, but in the preswhereby it may be turned and moved longitudinally. The central portion of the adj usting screw 82 is recessed asat 84, and such recess is engaged by a lug 85 extending from the fork.74, the construction being such that ,upon longitudinal movement of the adjusting screw 82, the fork 74 will vbe appropriately moved laterally.

In order to impart to the heel fork 74 its positioning movement and to insure that the heel shall be pricked in proper relation to the rear edge thereof, the slide .68 is provided with a swivel block 86, Fig. 5, which is engaged by the forked end 87 of a bell crank lever 88 pivotally mounted at 89. The a other arm 90 of said bell crank is connected by a link 91 to a lever 92 pivoted at 93 upon a bracket extending from one of the said plates or flanges 36. The lower end portion of the lever 92 is provided with a fork 94 which engages a lug 95 connected to a slide 96 which is itself provided with a swivel block 97 engaging the bifurcated end portion 98 of an actuating arm 99'. The arm 99 is pivoted upon the machine frame at 100 and at its end near the crank shaft 8 is provided with a roll 101 which is normally held pressed towardthe gear 7 by means of Y a spring 102 acting upon the arm 99 as 1nd1- cated in Fig. 1. Adjustably secured to the gear 7 as by means of the set screw 103, and sl0ts 104, is the cam 105 for acting upon .the

roll 101 as the gear 7 rotates, thereby im parting to the slide 96 and the connected fork carrier 69, its positive movement into engaging relation with the heel placed hetween the templet and the-follower block.

Since the heel positioning block 74 is given positive movement to position the rear or curved portion of the heel with respect to the awlsfthat the rear hole made by the awl may be the same distance from the rear of the heel, regardless of the size of the heel, it is desirablejto support the breast of the heel yieldingly, I

receive a so that the positivelymoving fork may,'when the heel is oversize, depress the said heel to bring the rear edge into proper relation with the rear awl.-

As one form of means to this end, the cap plate 11 of the machine as indicated in F ig; 1, may be recessed as indicated in Fig. 6 to yielding plate 106, said plate 106 being located as indicated in Figs. 1 and 2, below a heel positioned between the templet and follower block. The yielding plate 106 may be variously formed to yieldingly support the heel, but in the preferred form of the invention, as indicated in Fig. 6, the cap plate 11 is provided with the recessed portion 107 for the reception of the plate 106 portion of the plate 106 may he supported,

and a ridge or rest 108 on which the bottom The plate 106is preferably connected to the cap plate 11 by means of the screws 109, the construction being such that by proper adjustment of the screws 109; the position and the yielding character of the plate itself may be varied to suit the conditions of use.

It is the purpose of the present invention that the heels to be pricked be successively fed into the machine without danger of in: Jury to the operators hand; and to this end, a suitable feedin means is provided for carrying a heel from one side of'the e to a position between the templet and follower block.-

In the present form of the invention, said means comprises an arm 110, Figs. 1 and 5, pivotally connected at 111 to a lever 112.

The lever 11 2 has an arm 113 through which 1 passes an adJusting screw 114, the lower end bell chine toa position the follower block.-

'Contours of the if the arm 110, and

of which-abuts against a lug 115 carried by a spring 116 connected'to to the arm 110 as at'117 maintains the lug 115 against the the lug 113 and normally lower end of the screw 114, theconstruction being. such that the arm 110 may be normally moved by the lever 112, but should it meet an obstruction, said arm 110 may yield without causing breakage of parts.

The lever- '112 is connected to a, link 118, the lower end of which-is connected at 119 to one arm of a bell crank lever 120, said cranklever'120 being adjustably connected at 121 to the slide 96, the construction being such that upon reciprocating movement of the slide 96 through the arm 99, as hereinbefore described, proper oscillatory movement will be imparted'to the feed arm 110 to carry a heel-"from the side of the mabetween the 'templet'and heels between the tread and the 'heel seat surfaces vary. That is,

some of the heels have their side surfaces 'more inclined than others, and the present mvention contemplates the provision of means for engaging an-extended side surface of the heel, regardless surface of which of its inclination. 'As

one form of means to this end, the lower portion of the feed arm 110 is provided with a heel-engaging piece 122, the heel-engaging may be adjusted about an axis extending longitudinally of the arm 110, as by means of the set screws 123, the construction beingsuch that by adjusting the heel engaging tending longitudinally of the am 110, its heel engaging surface may be caused to be parallel with the it is to engage and thereby insure proper movement of between the templet and follower block.
