T 0 all whom it may concern:

Be it known that I, J osnrrr GoULDBoURN, a subject of the King of England, residing at Leicester, in the countv of Leicester, Eng land, have invented certain Improvements in Machines for Inserting Nails in I-Ieels, of which 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 machines for insert-ing nails in heels, and while many features of the invention may be used advantageously in other types of machines, the in vention is herein shown and described as embodied in a machine for attaching heels to boots or shoes.

An object of the present invention is to improve the construction of machines of this class so that they may be operated at a higher rate of speed than has before been possible.

A further object of the invention is the improvement of such machines so that they may be more readily adjusted to operate upon different classes or sizes of work than has been possible with machines as heretofore constructed.

I have shown the invention herein embodied in a machine for attaching heels to shoes by nails driven from the inside of the shoe. It will be understood, however, that features of the invention are capable of use as well in connection with machines for driving heel-attaching nails from without a shoe.

A novel feature of the present invention consists in the provision in a heel-attaching machine of a die-block provided with driver passages; a movable nailtransferrcr arranged to be reciprocated to supply successive sets of nails to the die-block for attaching successive heels, and a plurality of movable heel-holders arranged to be brought successively into attaching position by the successive reciprocations of the nail-transferrer- Another feature of the invention consists in novel means for presenting heel-blanks for the operation of the machine. In the preferred embodiment of the invention this means comprises a rotatable carrier for heel holders having radially disposed arms extending outwardly from a central hub, the arms being spaced substantially 120 apart and carrying on their outer ends the heel holders which are moved from receiving position to an intermediateposition and then to nailing position by an intermittent rotation of the carrier.

In this connection the invention contemplates also a novel mechanism for effecting the required rotation of the carrier. It has been found advantageous to divide each rotation of 120 into two movements. To this end cooperating cams may be arranged to rotate said carrier after the nailing. operation for any desired portion of 120, then to maintain the carrier stationary and finally to rotate the carrier for the remaining portion of the 120 necessary to move a holder into nailing position.

Another feature of the invention consists in the provision of a pressure-plate for engaging a heel, means for adjustably sustaining said plate in a position inclined longitudinally of the shoe and a heel-holder for sustaining a heel in line with the heel seat of the shoe arranged for adjustment simultaneously with said pressure-plate. In the construction shown, the heel-holder is carried by the pressure-plate so that the relation of the holder to the face of the pressure-plate is not changed by adjustment of said pressureplate. The pressure-plate is engaged by the tread face of the heel and is adjustable about an axis that is at or near the level of the heel seat of a shoe. Such adjustment permits driving the attaching nails at the desired inclination to the tread face of the heel.

The heels are held upon the heel-holders by gages arranged to engage the breast and rear of the heel and these gages are arranged for adjustment to accommodate heels of different sizes. To facilitate the adjustment of the several sets of gages the present inven tion also contemplates the employment of means providing connection between said sets of gages, whereby they may be adjusted simultaneously. As Will be obvious, the ar rangement may be such that the position of all the breast gages, or all the rear gages, or

all breast gages and rear gages may be simultaneously adj usted. In order that the centers of heels of'different sizes may occupy the same position on the heel-holder, the construction herein illustrated is such that the breast and rear gages may be simultaneously adjusted in opposite direct-ions upon the respective holders.

In the machine herein disclosed the dieblock will not always lie at precisely the same elevation in its nail-receiving position. To avoid the necessity of vertically adjusting the nail-transferrer for every alteration in theposition of. the die-block the, present invention includes a provision of means whereby the transferrer is mechanically moved vertically into close relationto the facev ofthe die-block in its. movement into nail-delivering position, and is restored to its initial position. when returned tonailreceiving position, The construction shown is such that the transferrer is. brought yieldingly into contact-with the face of: the dieblock so. that variations in position of; the latter, are mechanically provided for. This construction as will be, apparent is. particularly advantageous. when the face of the die-block has a somewhat convex configuration, the. face of the transferrer, being made concaveto fitthe die-block. In the embodiment of; the: invention selected for purposes of illustration the die-block is arranged to enter a shoe and tosupport the shoe. upon it. The die-block is arranged for movement intoandout ofattaching position to facilitate arranginga shoe in position upon it. The nails are supplied to the die-block while. the latter is in its inoperative position. To insure that the die-block will be in the precise position required to cause the nail passages of the transferrer to be in line with the nail cavities of the dieblock the present invention includes an arrangement whereby the nail-transferrer in its movement into nail-delivering position mechanically adjusts the die-block into proper position.

Other. features of the inventionv will be hereinafter describedzand defined in the claims.

In the drawings whichillustrate one embodiment-ofthe, invention, Figure 1 shows a side elevation of the upper portion of a heelattaching machine embodying the invention; Fig. 2'is aview infront elevation of the parts. show-ninFig- 1; Fig. 3 is aview in horizontal section of'the machine; Fig. 4

is a view, similartoFig. 3, illustrating a:

The drawings illustrate the present invention applied to a machine of the type shown in Letters Patent of Great Britain No. 5084 of 1903 to Bates at al. As will be evident from the nature of the invention, it is also applicable to other types of heel-attaching or heel-loading machines.

The machine shown in the present drawings includes, as in the prior patent above mentioned, a work-support 1 upon which Ithe boot or shoe to be heeled is placed and an oppositely disposed pressing member 32. ,The upper end of the worksupport is provided. with a die-block 2 having driver passages, and drivers carried by a driver bar 13 are arranged in these passages and are automatically actuated to drive nails through the sole of a shoe into a heel in the manner described in said patent. The work-support is arranged to slide in a horizontal 'guideway 4 carried by a vertically reciprocating member 6. The work-support is moved by the operator from the position indicated by dotted lines in Fig. 1' into that shown in full lines in said figure to place a shoe in attaching position.

According to the present invention a nailtransferrer 8 is employed to supply nails to the die-block 2 and as shown 18 arranged to convey nails from a nail-assorting and delivering mechanism 10 of any suitable construction to said die-block. The transferrer 8 is splined upon a vertical spindle 12 rotatably mounted in bearings lt upon the frame, said spindle having a handle 16 by means of which the transferrer may be reciprocated by the operator. In the movement of the transferrer S into nail-receiving position it is raised by means of a spiral cam surface 18 on the block 20 mounted upon the frame cooperating with a runner 22-upon the transferrer arranged to engage said cam surface. A spring 24; (see Fig. 2) tends to keep the runner 22 in engagement with the cam surface 18. The block 20 is preferably adjustably secured to the machine frame so that the position of the cam surface 18 may be varied to raise orv lower the path of movement of the transferrer. A convenient; construct-ion comprises .a nut 26 screwed upon the spindle 1 and engaging the lower face of the hub of the handle 16, said handle being splined upon the spindle l2, and the upper face of said hub engaging the block 20. The block 20 is secured to the machine frame by a rib and groove connection or any convenient construction permitting it to be adjusted in a vertical direction by the nut 26 and preventing its rotation.

A heel carrier 28 is provided with a stud 3O rotatably mounted in abearing 31 formed upon a slide 32 (see Figs. 3, 4 and 8). The slide 32 is sustained upon a foot 34, said foot being formed upon a curved slide 36 hereinafter referred to. The slide 32 is coupled to the transferrer 8 so as to move therewith. The construction shown includes a link 38 attached at one end by a universal joint 40 to the slide 32 and at the other end by a universal joint 42 to one arm of an elbow lever 44, said elbow lever being pivoted on an arm 46 (see Fig. 2) secured to a post 48 hereinafter referred to. A frame 50 is secured to the upper end of the spindle 12, said frame sustaining a vertical rod 52. A link 54 arranged to move freely upon the rod 52 is pivotally connected with the other arm of the elbow lever 44. As will be obvious the connections between the transferrer and the slide 32 permit the slide 32 to be adjusted vertically or swung about a horizontal axis if desired.

The heel carrier 28 is provided with a three-armed lever 56 (see Fig. 4) rigidly secured to the stud 30. Each arm of the lever is provided with a roller 57 at its end which, as the slide 32 is moved to and fro by the transferrer 8, is engaged in turn by two cam surfaces, one 58 formed on a plate (30 (see Fig. secured to the curved slide 36, and the other 62 being formed on a plate or member 64 pivoted to the curved slide. 011 the movement of the nail-transferrer into nail-delivering position, the roller upon one of the arms of lever 56 is engaged by the cam surface 62 and the carrier 28 is partially rotated to bring the roller into the position shown in Fig. 3. In the construction illustrated, this partial rotation amounts to about 75. In the move ment of the nail-transferrer into nail-receiving position the cam surface 58 is engaged by the roller shown in Fig. 3 and rotates the carrier 28 substantially 45 farther to bring a heel-holder thereon into alinement with the post 48. The plate or member 64 carrying the cam surface (52 engages a stop 66 on the curved slide 36 and is held from movement in the reverse direction by a spring, not shown, which permits a roller to pass by said plate 64 in the movement of the nail-transferrer into receiving position. The cam surface 58 terminates at its forward end in a recess arranged to receive one of therollers 57 on the move ment of the corresponding holder into operative relation with the driving mechanism, thus locking the carrier against angular movement until the slide 32 is moved rearwardly after the operation of the drivers.

Each heel-holder as illustrated comprises a back gage 68 having a V-shaped recess to receive the curved end of a heel and arranged to slide in guideways upon the carrier 28, and a breast gage formed as a straight bar 70 for engaging the breast of the heel. Each breast gage is carried by a plate 72 arranged to slide in guideways toward and from the back gage and is yieldingly held toward the back by a spring 74. The plates 72 bear against the tread surfaces of the heel blanks and serve to position them properly for presentation to the upper pressing member 32. To permit all the back gages 68 to be adjusted simultaneously, rack bars 76 are formed upon them and are arranged to mesh with a pinion 78 rotatably mounted on the stud 30. Integrally with the pinion '78 is formed a beveled gear 80 (see Fig. 5) meshing with a second beveled gear 82 mounted on the shaft 84 journaled in the slide 32 and arranged to be actuated by the operator. During the rotation of the carrier 28 in the operation of the machine, the shaft 84 will be turned idly by the gear 80 which rotates with the carrier, there being sufficient frictional resistance to movement of the back gages on their support toprevent them from being moved relatively thereto in the rotation of the carrier 28. Each breast gage 70 when no heel is in the corresponding heel-holder is held by its spring 74 in engagement with a wedge-shaped block 85, a projection 83 upon said breast gage coming in contact with said block. The wedge-shaped block 85 is carried by the adjacent back gage 68 so that as the back gages are adjusted by the operator toward or from the center of the carrier 28, the breast gages are adjusted in the reverse direction. As will be obvious this construction permits heels of different sizes to be conveniently inserted in the holders and to be retained upon the holders with their centers in substantially the same position.

The post 48 is mounted for vertical adjustment in the head of the machine and is held from rotary motion therein,a hand wheel 86 being provided to facilitate its adjustment. The curved slide 36 is mounted in guideways 88 formed upon the lower end of the post 48 and said slide is provided with means for adjusting it in said guideway,'a convenient construction including a worm 90 carried by a spindle 92 journaled in the post 48, said worm engaging worm teeth formed upon the curved slide 36. By adjusting the slide 36 in its guideway the carrier 28 may be sustained in an inclined position so that a heel against which the heel seat of a shoe is pressed may be held in an. inclined position and the nails consequently driven in an oblique relation to the lifts of the heel. As shown in Figs. 1, 5, and 8, the machine is adjusted for inserting nails at an inclination to the tread face of the heel. The guideway 88 is preferably curved in the arc of a circle, having a center at or near the level of the heel seat (see ment.

Fig. 8) so that the pressure-plate formed by the slide 36 cooperating with the breast gages with which the tread face of the heel come in contact is adjustable about an axis that is approximately at the level of the heel seat. The post 48 is slotted at 94 (see Fig. 4) and a clamping bolt 96 actuated by a handle 97 is provided to cooperate with said slotted post to hold the curved slide 36 in adjusted position.

The nails are delivered to the die-block 2 with said die-block in its outer position shown in Fig. 3. To insure that the the block shall be in proper position for the recept-ion of the nails, the machine shown in eludes means for adjusting it into correct position in the movement of the nail-transferrer into nail-delivering position. This is shown as a lever comprising arms 98 and 99, said lever being pivoted upon the frame at 100 and actuated by the transferrer 8 by means of alink 102 connected to arm 99 and an eccentric 104-, for actuating said link said eccentric being secured to the spindle 12. A lug 106 is formed on the work-support for engagement with the arm 98 so that when the tranSferrerS is moved into nail-delivering position, as shown in Fig. 3, said arm 98 will move the die-block outwardly in case itis not in its outermost position, a suitable stop device, not herein shown, being provided if desired to limit outward movement of the die-block.

In the operation of the machine above described, the work support being in its outer position, the nail-transferrer carrying a gang of nails is moved by the operators attendant into nail delivering position above the die-block. In its movement it adjusts mechanically the die-block into proper position to cause its nail cavities to be in line with the nail passages of the trans ferrer when the latter is in position above the die-block, and also moves a heel-holder in which a heel has been previously inserted by the attendant part way toward attaching position. The nail-transferrer is brought into close relation to the face of the die block by the spring 24:, which yieldingly depresses said transferrer in its move- The transferrer after delivering its nails to the die-block is returned by the attendant to receiving position. In its return movement it is raised by the cam 18, so that in receiving position it is in close relation to the nail-supplying mechanism. Also in its return movement, it completes the movement of aheel-holder into attaching position. A shoe may then be placed upon the work-support by the operator, the

work-support moved into attaching position and the machine started which thereupon automatically lifts the jack to place the work under pressure, as in the machine of the prior patent above mentioned, and

' drives the nails from within the shoe into the heel. After the operation of the drivers the jack descends and the heel which has been attached to the shoe is drawn downwardly out of its holder. While a shoe is being heeled, the attendant may insert a heel for the next shoe in the holder next to that in attaching position. It will be evident that a greater or less number of heelholders than three may be employed. lVhere three are used the holders may be conveniently reached from the side of the machine, as will be apparent from Fig. 4.

hen a change is made in the size of the heels being attached adjustment of the gages is desirable. It will be seen that in properly adjusting the gages upon one holder to fit a heel, the gages upon the remaining holders are simultaneously adjusted to the same extent, and separate adjustment of the gages upon the different holders is thereby rendered unnecessary. In case adjustment in inclination of the pres sure-plate is desired, it may be secured by adjusting the curved slide 86 in its guideway, since the carrier 28 for the heel-holders is'supported by the slide 36. It will be seen that in adjusting the latter, adjustment of the former to the same degree of inclination is secured. The adjustment of the slide 30 is about an axis located at or near the heel seat of the shoe as shown in Fig. 8, and it will be noted that this feature is advantageous in that the heel may be adjusted in inclination without displacing its heel seat face longitudinally of the shoe.

As will be apparent from the above description, modifications in the machine herein disclosed. could be made without departing from the present invention. For example, the machine shown could be adapted, if desired, to secure successively to a shoe a heel blank and a top lift. It may also be observed that the term nails herein employed is intended to include slugs or other equivalent devices.
