inserted in a heel preparatory to its attachment to a shoe. v

The object of the invention is to expedite the operation of such machines so as to greatly increase the output thereof, and thus reduce the cost ofmanufacture of a shoe.

In the illustrated embodiment of'the invention, this objectis accomplished as folthrough the machine on a plane above the fcarriers for the heels and the nail-holders. Fig/leis a fragmentary sectional view illus- 5 trating the raceways and the adj acentmechfanism. Figs. 5 and 6 illustrate ,the pick, ing device which cooperates Withthe ,ends of the raceways for-simultaneously picking the required number of nails. Fig. 7 (Sheet %3) represents a section on the line 7-1-7 of vFig. 4. Fig. Srepresents an enlarged verr t'ical section throughthe rotatable carriers for the heels and thenail-holders. Fig.9 lrepresents an enlarged section through the mechanism for feeding the nails to their carriers. ,Fig. 10 is (a fragmentary view Z-illustrating the ends of two raceways and the passageways leading therefrom to regceive the nails as they are picked. Fig. .11 rep resentsin plan viewthe carrier for the lows: I provide a plurality of holders for.

the nails or other fastenings, which are moved successively into operative relationto heel blanks likewise successively fed into proper position. The nails,or other fastenings, are supplied from a suitable source through raceways to thenail-holdersasthey I v n t have illustrated as embodying the invention;

are successively moved into 'a nail-receiving position. 1 The nail-holders are mounted upon a rotatable support or carrler which is advanced with a step-by-step motion so as to bring each holder, after it- 'has been sup:

plurality of drivers mounted upon a driving head by which the nails are-driven into a heel blank placed therebeneath. The heel blanks are presentedsuccessively to the nail-holders and the nail-driving mechanism by means of a carrier which is preferably arranged to rotate about an axis with a stepby-step movement. Arranged 1n proximity to the carrier, there is a punching mec'ha nism comprising ahead with a plurality of awls or punches for forming perforations in the heel blanks prior tothe insertion of. the nails, so that, in the operation .of'the machine, each heelis first perforated and then moved into position to receive the nails which are forced. into it by the drivers, and then discharged from the carrier, by a suit able mechanism. Referring to the accompanyingdrawings, Figure 1 represents a front elevation of a machine embodying the invention. Fig. 2

represents the side elevation of the same.

Fig. 3 represents a horizontal section 'Ehee ls. Fig. l 2 represents a sectional view jthrough the carrier and its inclosing casing, together with the parts immediately there'- beneatli. Fig. 13 illustrates the device which controls the clamping of the heels.

Before describing: ythe machine I which I I desire to have it understood that the inventmn maybe embodied in' various other forms of the machine and is not limitedito: fthe details of construction and arrangement which I have illustrated, nor to loadingthe. heel blanks; with the particular kind :of

fasteners shown and described; and that the.

phraseology whichI have employed is for the purpose of description andnot of limitation.

y The machine-is illustrated as having an upright main frame substantially rectane gular in plan view. It has the base 20, the sides 21, 21, which are suitably connected by form, such for. instance, as that'1to be de-' scribed. A main driving-shaft 27. is jour- A cross-head 23, which, in the naled in the frame and has on its projecting end fast and loose pulleys 270, 28, with which may be engaged a driving belt. The said shaft 27 carries a gear 29 intermeshing with and driving a gear 30 arranged on a shaft 31 ournaled in the frame. said shaft is affixed a disk 32 having a camgroove 33. Secured to the two upright bars 24, 24, near their lower ends is a cross-bar 34 which is equipped with a roller 35 entering the cam-groove 33, so that, as the shaft 31 is rotated, the cam efi'ects'the reciprocation of the cross-head 23.

Arranged above the table 22 are two rotary carriers 36 and 37, the former being for the heel blanks and the other for the nailholders, as illustrated in Fig. 3. The carrier 37 overlaps the carrier 36 (see Fig. 8), being arranged in a plane aboveit, so that a nailholder may be positioned above a heel blank. The carrier 36 is mounted upon an upright shaft 38 journaled in the table 22. On the lower end of the shaft 38 is .a disk or wheel 39 which forms the driven member of a Geneva stop-motion, the other member 40 of which 3) is secured upon an upright shaft 41 journaled in the frame. The shaft 41 is equipped with a bevel gear 42 with which intermeshes a driving bevel gear 43 on the shaft 31 hereinbefore referred to, as illustrated in Fig. 2. The member 40 is provided with an arm 44 carrying a roller 45 adapted to successively enter radial slots or grooves 46 in the disk ofmember 39, to impart a step-by-step rotation to said member and consequently to the heel-blank carrier. The member 39 has its periphery concaved as at 47 to receive the convex portion or peripheryof the member 40, and hold said member 39- at a state of rest after it has been fed one step and until the-roll 45 enters the next succeeding groove or slot therein. The

Geneva stopmechanism, or other power transmitting mechanism whichmay b'e employed in lieu thereof, is so constructed that the carrier for the heel blanks will be advanced one step, as through an arc of 90 for each complete rotation of the shaft 41; and as the bevel gears 42, 43, have the same number of teeth, the cross-head is reciprocated once for each advancement of the carrier. The parts are so timed that thecarrier is advanced as the cross-head is completing its upward stroke and is descending through the first portion of its downward stroke.

Secured upon the table 22 is a hood or casing 50. This is inthe form of an inverted cup with an outstanding flange 51 which is secured to the tableby suitable fastenings. The casing is cut away at its rear portion so as not to overlap the carrieri37. It is provided with an aperture 52 at the front through which the heel blanks maybe fed to the carrier. Over this aperture may be Upon placed any suitable chute or feeding device for supplying heels automatically to the carriers. As shown, the heels may be supplied successively by hand, but I have contemplated utilizing any one of the various feeding mechanisms that have been heretofore suggested for successively feeding them. At 53 there is another aperture in the hood or casing to the right from that at 52 and at an angle of 90 therefrom. This aperture is located over the point at which the heel blanks are discharged from the heel-carrier after the loading operation has been completed. To the left of the aperture 52 and at an angle of 90 therefrom, there is detachably set into the hood or casing a disk or block 54 having a flange 55 (see Fig. 12)

overlapping the upper surface of said hood.

-This block or disk is provided with a plurality of apertures '56 through'which the awls or punches may descend for the purpose of forming perforations or holes in the heel blank.

The carrier 36 is provided with four radial slots 57, as shown in Figs. 11 and 12. The end wall 158 of each slot serves as a guide and clamping member, against which ,the breast of the heel blank is forced by the complemental clamping member 58, of

which oneis placed in each of the slots. Each clamping member 58 is provided at its inner end with an upstanding pin 59 projecting upwardly through a radial slot 60 in a disk 61 placed upon the shaft 38. Each of the clamping members 58 is forced yieldin l outward b a s Jrin 62 arran ed in a a y a: b

socket in the inner end of the member and bearing against the inner end wall of the slot 57 as shown in Fig. 12. For the purpose of controlling the movable clamping members 58 so that they will, at the proper times, engage and release the heel blanks, the hood 50 is centrally apertured to receive the upstanding ends of the pins 59 and also to receive a cam-guide 64 formed on a plate 65 suitably affixed upon the said hood, (see Figs. 12 and 13). The cam 64 is stationary, and, as the carrier 36 is advanced step-bystep, each pin 59 engages said cam and is forced inwardly so as to release the heel clamped by the member which carries the said pin, as the said member reaches its discharging positlon. The cam 64 is long enough so that the clamping member 58 is held in ts withdrawn position until the carrieris advanced one step, so that the heel blank may be fed into the carrier in posi tion to be clamped. As soon as the carrier begins the next step, the pin rides off from To prevent the heel carrier at the front of the machine a stationary support 66, as shown in dotted lines in Fig. 11, and in full lines inFig. 8.

The carrier 37 for. the nail-holders is formed with a hub 67, and itis loosely journaled upon an upright shaft 68 fixed in the table.22,1as illustrated infFig. 8. To said hub 67 thereis attached a gear 69, which intermeshes with gear teeth formed on the periphery of the carrier 36. The ratio of the'toothed carrier 36 to the gear 69 is as 2 to 1, so that as the carrier 36 is advanced through an arc of 90,,the carrier 37 isadvanced through anarc of 180. In case the carrier 37 has a greater number of nailholders than is shown, the ratio will be correspondingly changed; The carrier 37 is formed with apertures to receive a plurality (in the present instance two) of the nailholders 7 O. The apertures are circularz and the nail-holders are cylindrical, being pro vided at their upper edges with peripheral flanges 71 so that they may be easily secured in place by suitable fastenings, as, for

instance, screws 72.. The nail-holders are.

arranged diametrically opposite from each other and are equi-distant from the axis of the rotation of the carrier. As the heel blank carrier is advancedone step, a nailholder is brought into registration with a heel blank, so that the nails carried by the nail-holder may be driven into the heel blank and into the perforations or'apertures previously formed therein, as illustrated in Figs. 3 and 8. Each nail-holder is provided with a plurality of apertures 73, properly I spaced to receive the nails, each nail-holder in the present case being shown as provided with nine of said apertures. The nail holders are removable and I provide for each machine a plurality of such holders for heels of different sizes. The nails are fed into the nail-holders successively, one nail-holder beingfilled with nails, while the other isin position to permitthenails therein to be driven into the heel blank; In order to prevent the nailsv from dropping through the apertures in the holders until the proper time, I formradial slots or guide-ways 74 in the under side of the carrier and place therein slides 7 5,, each slide carrying a plate or gate 76, which is provided-with perforations equal in number to and spaced correspondingly with the apertures in the nail-holder under which the plate lies. .Each plate is removable from its slide so that it may be replaced by an: other one corresponding to theholderuwith which it is to be used. The slides and plates are movable from a position where cheap ertures in the plates. register with the apertures in the nail-holders, to a position where the imperforateportions of theplate are beneath the apertures 7 3, and toaccomplish this each slide 75 is provided with an upstanding pin. 175., onwhich there is a roller 77. These rollersextend into a camc groove '78 in a cani'disk 79, rigidly affixed, I

as by a screw 80, to, the upstanding shaft 68. The disk 79 is so placed and the cam groove is so'formedthat just as a nail holdermoves into position toregister with a heel blank on the heel blank carrier,,the plate 76be neath said holder is moved radiallyoutward to cause these perforations'to register with the'perfora'tions in the holder, and thus permit the nails to be discharged.

The cross-head 23, which I have previously described, isprovided with twoheads, v

80 The headfor the awls driver head 82 is dove-tailed into the crosshead 23 and it ,islocated above the floverlapping portions of the heel :blank carrier.

36 and the nail-holder "carrier 37, so that the driver 84 willregister with the apertures I in each nail-holder as it reaches a position of registration with a heel blank on the heelblank carrier. I provide for each machine a plurality of awl-carrying and nail-driving heads for heels of difl'erent sizes or' shapes with the awls and drivers properly, spaced for the purpose. Q

As thus far explained, it will beunderstood that each timethecrosshead 23 is reciprocated, the heel-blank carrier is advanced one step through an arc of'90 and the nail-holder carrier is advancedone step through an arc of 180. As the'cross-head moves downward,; the awls form perforations in one heelblank and the drivers, ,en-

tering the apertures in'the loaded nail-' holder, drivethe nails therein into the apertures formed in the heelblank, which was previously perforated by the 'awl.

For the purpose of resisting thethrust I of the awls upon the heel blanks, I place jack under the awls and below the heelblank carrier, as shownin Figs. 1 and 124 This jack is indicatedat 87 and it is mounted upon-the upstanding spindle 88, which is arranged to slide in aguide 89 formed in the table 22. The lower end of this spindle is pivoted to a lever 90 fulcruined at 91 to one of the side walls of the frame. The said lever has a roll 92 placed in a cam groove 93 in adisk 94: rigidly secured upon a shaft I 95 extending from front to rear of'the machine and ournaled insultablecross-braces.

The shaft is ro tatedby beveled :gears 96, 97'

(seeFig. 2), the former being secured to the shaft 41', and the latter to the 'shaft95. The bevel gears have the same number of teeth and are of the same size, so that thejack 87 is raised to engage and support the heel hlank registering therewith, each time the cross-head is reciprocated, whereby the heel blank is supported against the downward thrust of the awls. It is also necessary to support the heel. blank during the operation of driving the nails thereinto. Consequently I place below the driving head 82 andbeneath the heel blank carrier a jack 1 11, as shown in Fig. 8. This jack, as well as that at 87, is shaped to conform to the curved face of the heel. It is secured upon a spindle or rod 1&2 which is adapted to slide in a bearing 143 formed on the table 22. The lower end of the spindle is provided with a roller 1414 (see Fig. 2), which enters a camgroove 145 in the cam disk 94 hereinbefore referred to. The cam groove is so shaped that the ack is raised to engage the heel immediately prior to the engagement of the drivers 84: with the nails so that the insertion of the nails in the heel blank may be properly accomplished. The operation of the two jacks by the single cam disk insures theiraccurate cooperation with the awl and driver head in pricking the heel blanks and driving the nails. After each heel blank is loaded and the clamping memberis withdrawn, as previously described, it drops from the carrier upon a chute 98 which extends through the side of the hood 50, as shown in Fig. 1.

For the purpose of indexing the carrier 37 and thereby causing an accurate registration of the drivers with the apertures in the nailholder, the carrier37 is provided with two apertures 99 which are diametrically oppositely arranged as shown in Fig. 3, and the cross-headis provided with an indexing pin 100, the lower end of which is tapered so that as the cross-head descends,,the pin will enter the forward aperture 99 and accura'tely locate or position the carrier 37. The pin may be made long enough, as shown, so

as to pass through the aperture 99 into an aperture 101- in the heel-blank carrier and in.- dex that likewise, although I do not find this to be essential. 1

I will now describe the instrumentalities by which the nails are supplied to the nailholders from one or more sources of supply. 5

I provide a plurality of nail-hoppers, in the present case employing .two, although more or less may be used. Each hopper has a rotary drum 102 mounted upon a shaft 103 journaled in a bracket 104, and an initial nail-receiving pot 111, with an inclined bottom 112, whlch discharges in the rotary portion 102 ofthe hopper. The drum of each hopper is provided with lifting buckets 105 for lifting the nails and discharging them into theracewaysa The drums 102 are rotated from a transverse shaft 106 journa-led in the sides of the main frame. On the outer ends of this shaft are belt wheels 107, from which belts 108 extend to the drums, being placed in peripheral grooves therein. The shaft 106 is provided with a worm gear 109, with which intermeshes a worm 110 on the end of the shaft 95, hereinbefore described.

Between the pots 111' there is a plate 114:, as illustrated in Fig. 4. This plate forms a support for the lower ends of the raceways, the picking mechanism and the guides for the nails. I employ as many raceways as there are apertures in each nail-h0lder. In the present instance, I have illustrated nine raceways, four extending from one hopper and five from the other hopper. These raceways areindicated at 115 and 116, those leading from one hopper being indicated by the former numeral and those leading from the other hopper being indicated by the latter numeral. The raceways in each set are placed side by side at an inclination both to the vertical and to the horizontal, and lead from the drum 102 through the pot downward to a block 117, which is superimposed upon a block 118 secured to the plate 114, by one or more screws 119, as shown in Fig. 9.

I Each raceway consists of rabbeted bars 120,

120,.secured together, as shown in Figs. 5 a and 7, and a cover 121 separated far enough from the upper edges of the bars-to permit the free passage of the nails down the raceway. The block 117 is provided with an 5 aperture 122 at the end of each raceway, the

aperture being of irregular form or keyhole shape, as shown. The nails a are illus- ;trated as of the usual character employed i for loading heels, (being known as collar nails), and have heads and collars or flanges 3 immediately below their heads, though fastenings of other kinds may be employed. As each nail passes from the end of the race- '=\vay, it drops into the smaller end of the aperture 122 and its downward movement is arrested by theengagement of its collar with the surface of the block surrounding :the smaller portion of the aperture. These apertures 122 are suitably spaced, being substantially in the same relatioi to eachother gas are the apertures in the nail-holder, and consequently some of the raceways are longer than others, as shown in Fig. 5.

1 thereof.

A suitable picking mechanism is utilized to move the nails from the smaller portions of the apertures 122 to the larger portions For convenience, this picking mechanism consists of a single picker 123, which has at its edges notches 124C for the nails, adapted to register with the ends-0f the raceways and with the smaller portions of-the apertures 122. The edges of the picker 125 adjacent the notches serve as stops to prevent the feeding of the nails through the raceway when the picker plate IiS advanced, as will be explained. The said picker is formed with an elongated slot 126 through which a guide 127 extends, said guide being secured to the block 117 by a screw 128. i

129' is an inverted L-shaped lever of which the lower end is fulcrumed upon a stud 130 carried by ears formed 011 a cross-bar 131.

The ends of the cross-bar are affixed to the guldes or bearings 26 on the table 22. The;

lever 129 has at the junction of its two extremit'ies'a stud 132 which occupies a cam slot 133 formed in a'plate 13 i affixed to and .movable with the cross-head 23.- The upper extremity ofjthe lever 129 is pivotally connected to the nail picker 123 by means of a link 135, and the cam slot 133 is of such shape that, as the cross-head moves down- Ward, the picker 123 is moved rearward and the notches 12% therein carry the lowest nails a in the raceways rearward topermit them, to drop through the larger portions of theapertures 122; hence, each time the picker is moved rearward, the proper number of nails are simultaneously discharged,

from the raceways, and, through the means to be described, are delivered to the na1l holder which is in position to receive them.

The block 118 is provided with apertures 136 registering with the larger portions of the apertures 122 topermit the passage of the nails therethrough. The blocks 117 and blocks 1.17, 118, 138. 139 and the tubes 137 of which extend into ablock or plate 138,

and the lower ends of each extend into a smaller block or plate 139, which is in a plane immediately above the upper surface of the carrier for the nail-holders. ,The

blocks or plates 138, 139, are secured to gether by ascrew lLO. The plate 138 is dovetailed into the underside of the supporting plate 11,Ias shown in Figl, and,

it is held against movement by a set-screw 141. The supporting plate 114 is apertured as at 1 1 1, to communicate with the passages through the tubes 137 and'the blocks or plates 138 139. The passages inthe all constitute conduits for leading or guiding the nails from the picking mechanism and the raceways to the nail-holders. I RI have shown thevarious parts last referred to as detachable, so that thev maybereplaced ,byotherstadapted for heel-blanks of other sizes. The arrangement and spacing of the delivery endsjof the raceways is pre The picker is reciprocated by the following devices, although other power-- transmitting mechanism may be employed.

'cisely'the same as that ofthe nail apertures otherL Furthermore, the delivery ends of the raceways are so arranged with relation to the conduits; that the nails move all in thesaine direction when" being transferred from the raceways to the conduits.

due to this arrangementof the raceways by It is evident thatotherforms of guiding means mightbeutilized than those I have described.

variousxparts has been set forth in connecto state that for each reciprocation of the cross-head a heelblank is fed and perfothe drivers, and a loaded blank is discharged from the heel-blank carrier. The picking mechanism is operated to permit the-discharge of a proper number of nails position over the perforated heel blank, and the .nails are driven therefrom into the blank. Each heel blank is thusmoved first punchedthereinby the awls, thence towa position where it receives the nails from where it is discharged from the carrier through the chute 98 intoa suitablereceptacle' provided for the purpose.

It 1 will be observed that, while the awl holders and theirgates, and the blocks and -co'nduitsfor thennails are all detachable as previouslyjdescribed to be replaced by others particularly adapted for heel blanks of other sizes or. shapes, the clampingmembers onthe heel blank carriers are not necessarily deends with'reentrant angles, orV-shaped ,re-

engage and properly positionheel blank s of for larger or smaller heel blanks as the case may require. To secure the same elasticity of the machine with reference tothe mechanism for delivering the nails to theholders, it will be seen that theraceways are not rigidly or unremovably attached; on do the contrary" the removable blocks 117, and 118 =of the raceways are frictionally inserted, and the racewaysare laterallyadjustable so that they may be operatively engaged with the The simplicity of the transferring device .123 is i The operation of "the machine need not be described in detail,las the operation of the,

In some cases, instead of adjusting the race ways and all the blocks, I have contemplated making only the blocks 138, 139 and the tubes removable, and replacing them by others in which the conduits therethroughout attempting to set forth all of the forms in which it may be made or all of the modes of its use, what I claim is 1.
