I-IEEL-NAILING MACHINE.

To. all @hom 'it may con-cern:

Be it known that I, BENJAMIN F. MAYO, la

4citizen of the ,United States, residing at taching hee s to boots or shoes.

The invention is herein shown and described' as embodied ina machine of the type shown in United 'States Letters Patent, No. 694,656, dated March 4, 1902, in which a -nail block is-supplied with nails from automatic assortin'g anddistributing apparatus. The

machine described in said patent contains a die-bed spindle moved verticallv in suitable guideways by a toggle and link, the latter being actuated atthe lproper Atimes byA a clutch controlled shaft W vch when' started is rotated twice in succession andthen stopped, the'V upper 'end of the die-bed spindle having a driver-head supporting a serles of drivers. The said machine also includes a nail-assort ing mechanism adapted to supply nails with their heads all in one direction to a nailcarrier or transferringdevice shown as comprising a swinging'arm movable by the operator from the nailook.

' support is withdrawn letting' the nails drop transferrer into the nail-'b from the transferrer intothe nail-block.

In this present invention I have provided a nail-guide to guide nails assing fromv the ook.; and I have also provided the transferrer with a gage to better sustain nails of different lengths- `I have also provided a novel heel and topi lift holder and have actuated it in novel my invention, the trans manner; and have provided a novel connection between the nail-transferrer and the device common to said patent for preventing erating the the starting of the shaft for o errer is not die-bed spindle when the trans in its nail-receiving position.

The framework A, the clutch controlled shaft A the clutch controlling lever D, .the shaft a having the toes a/ and a2, the lug a5 carried by the roda yand controlled as to its osition by the position of the nail-trans-- errer so that the shaft A may be started b'y the operator through the treadle a3 only when the transferrer is in its position to receive 'nails trolled link f4, top-lift plate -and actin the drivers d; the -sprii'ig-constituting the' plvot for the nail-transferrer, are

and maybe substantially as shown and described .in said patent. f The shape ofthe driver carrying head Ea differs 'from that shown in '-said patent, in

elevated above the driver-'head E6.

that it has at its opposite ends, see Figs. 1 and 12, bearings closed by capsl E, to receive grooved collars -from which de en'd guides EEl which sustain he lower en s of strong springs E",-'said prings receiving through them reduced portions 67X of rods E. tted to slide in the bearings of the head E, the lower aids of the 'rods being extended through said guides, said springs actin@ at their upper ends against washers 88X a utting against shoulders on\ said rods7 and keeping them and the nail-block head a nail-block head carries a 'nail-block al vided with holes for the reception of nails and over which moves the heel and top-lift holder Ee1" to be described.

As the spindle E4 is lifted, a heel being held in, the heel-holder, the driver-head E and nail-block head a. rise in unison until the upper side of the heel meets the .sole of the shoe held on a jack, and after the ressure of the nail-block on the heel has exerted to the proper amount measured by thes rings E", the nail-block head is sto ped, but t e driver-head continues to rise, siiding upwardly on the rods 'E7 and' compressing the prings E, the upward. movement of .the

iver-head independently of the nail-block head causing the drivers d to rise in the holes in` the nail-block, and acting against the heads of the nails in said block drive them `from the block into and through the heel to-attach the same to the sole.

The provision of sliding the Adriver-head on the rods sustaining the nail-block head and compressing the springs E9 is'not of my invention and is not herein claimed.

The lower end of the post c2 hasl clam )ed upon it by a clamping screw (L12 the split iub o an arm als having at its opposite end a,

split sleeve which receives the shank of a catch a14 forming part of means for holding the nail-transferrer in its nail-receiving position. The shank of the catch is clamped in said'sleeve by a clamping screw w75; The

arm a of the transferrer shown has at oneend a hand-piece a and at its o posite end is secured to a hub als, which is 'ree to turn on the post c2. The transferrer has another arm a, provided with a stud a2 which enters a hole in a sliding rod am free to reciprocate in a sleeve 122 connected with the upper end of the rod'af, before described, said rod having at its lowerend, as shown in Figs. 2, 9, 10, 12 and 13, the luga5 which coperates with the/stop finger a2 common to said patent.

. As the transferrer is swung from its position shown in Fig. 8 into the position shown in Fig..9, so that it may give up its nails, it immediately Vturns the lug ai into position underneath the toe a2 so that under no circumstances can the machine be started to. actuate the drivers until afterthe transferrer' The' pro-

plate having a rim Z215 to rest upon said arm,l

said receiver having in practice a wat number of nail holes to provide for diii'erent nailings, and being represented as chambered at its upper side to receive a gage plate bw having its nailholes arranged 1n the proper order for the particular driving desired.

Thegage plates used will vary as to the arrangement of their nail holes according to the outline of nailing required. The gage late for short nails may he in the bottoni o the recess of the receiver, as in Fig. 6, or for long nails it may occupy a position nearthe top of said recess, see Fig. 7, the gage plate at such time being supported on aring, ast7 which maybe of wire sprunor into the recess in the receiver. The gage plate has two guide pins 518 to enter holes 4 in the receiver, that the nail holes in the gage'plate and receiver may! be` kept in alinement. The nail-block al i has holes b1 to receive the nails 2 from the transferrer. The arm am of the transierrer is provided with a stud 01 upon which is pivotally mounted a nail-sustainer ci?, the tree end of which occupies a position under the nail-receiver, as represented in Figs. 1 and 6,

when the. nails are fed into the said receiver from the usual nail-asserting mechanism, not shown, but which may be common to said patent, said nail-sustainer keeping the nails in the holes of the receiver whilethe trans- 'ferrer is being moved from its nail-receiving .into its nail-delivering position. VThe nai]- tering a hole in the stud (L20 before re erred to,`

said spring when the sustainer is released from t e stud 015 immediately moving the sustainer` from under the receiver, see Figs. 7.

and 9, 'freeing the nails so that they drop by gravity into the holes of the nail-block.

As the nail-receiver, b of the transferrerv arriyesjn its nail-delivering position, Fig. E),

` the holes therein having been placed in a inement with the holes in the nai -block, the ear cl3 of the nail-sustainer meets the lStop om( that depresses the sustainer and disengages s )ring down to disengage it from the stud 01,5. f

he nail-sustainer when released as described is moved by the sprin c into the position shown in Fig. 9, the en of the arm of the sustainer beyond its pivotal point c1 striking the hub a1B of the transferrer arm and'stopping the sustainer in said position.

In order that the holes in the receiver ma be exactly alined with the holes in the nai e block, I have provided the transferrer arm al" with an adjustable stop c whichV is arranged to contact with a nut l0fscrewed upon a threaded projection 12 of the nail-block holder. The vnail-sustainer c1B has a lip 02"* which, as the transferrer is'returnedf'rom its position, Fig. 9, into the position, 8 meets the shoulder 3 of theY catch a which forces the nail-sustainer into operative position under the receiver as the transferrer comes into nail-receiving position. Stopping the sustainer in advance of' the transferrer arm a on the return movement permits tlle lower end of the stud C15 on said arm to move to a position over the hole c14 of the sustaincr, said stud locking the sustainer in proper vposition to support the nails discharged from the nail-asserting mechanism into the holes of the gage plate and the' nailreceiver.

The holes in the receiver m-ust be exactly positioned. with relation to the usual deliveryr tubes supplied with nails from `the nail- -assonting` mechanism, which may be such as provided for in said patent, or any suitable tubes leading-from a nail-asserting mechan-A ism, and to insure this position I employ an adjustable stop c2l carried by the arm al,

said stop also meeting the face 3 of the Catch lo referred to.

Wlienthe transferrer is to be turned from the position, Fig. b-, where the nails are supplied to its receiver, the o )erator by pulling Aon the hand-piece (157 will disengage the hook bl from the catch a and swing the trans' 'ferrer by hand toward nail-delivering position until the stop c meets the nut 10;

In machines as heretofore constructed diilicultywas sometimes Inet with in guiding and dellvering nails correctly into the holes b1? of the nail-block; said difficulty arising from the fact that the underside of the nailreceiver, when the transferrer was in position to deliver nails, stood in a plane above that in which the top if the heel and top-lift carrying plate moved, and consequently there was considerable space between the upper side of the nail-block om and the underside of the receiver. When this space is greater than the length of the nail, the nails cannot be delivered with certainty into the holes in the nail-blocli 'and consequently I have providedy a nail-guide d10, having a series of holes 5 which are in alinement with the holes in thenaibreceiver, and this nailguide is sustainedA for the beet results from the underside of thereceiver by means of stands 7, re resented in full lines in Fig. 1 and also in ig. 7. The nail-guide is located sufliciently below the lower end of the nailreceiver and the lower side ofthe arm al to afford space for the nail-sustainer.

Figs. 6 and S show the nail-sustainer in position to.sustain the nails, it occupying the position shown until the arm all arrives in the position, Fig. 9, at which time the sus# tainer7 as has been described, is withdrawn from under the heads Aof the nails7 letting the nails, see Fig. 7 drop throuGh theholes in the nail-guide and enter the h. es bw in the nailblock. The nails dropped into the holes are arrestedin usual manner by the up er ends of the drivers d contained in the nai -receiving holes in the nail-block, as provided for in said patent.

I believe .I am the first to provide a nailguide, occupying a.' position between the nail-transferrer and the top of the nailblock, and Iv desire to claim this feature broadlyJ irrespective of its construction, and in whatever form it may be employed. rIfhe lower side of the nail-guide is located in a horizontal plane as close as practicable'tothe upper side of the nail-block and all the nails' invthe'receiver and rest'ing uponthe sustainer will drop from-the' receiver and be guided through the holes 5 of the nail-guide on their way into the holes b1 of the nail-block.

The arm a-16 of the nail-transferrer has anv ear d and extended upwardly therefromis aA 110 projection d, which, When the transferrer 1s moved toward position to receive nails, meets the inclined face of a pivoted contact piece 25 at the end of a rod al, held loosely in a boss or arm A10 extended from the framework and shown only in Fig. 1, which moves a suitable device to start into o eration nailassorting mechanism, as provi ed for in said patent7 so that said n1eclianism may immediately discharge a series of nails to enter the holes in `the receiver of the transferrcr. In the vmovement of the transferrer toward the nail-block the contact piece 25 turns about its pivot to permit the projection d to ass by the rod (NOX.

he stud ci on the transferrer arm al has connect` to its lower end as herein shown, a jointed actuatord, represented as composed of two iplartsunited by a pin d1, said parts bemg rther connected by a spring d, 130

which sprlng and inwill permit the free end of the actuator t e turned down if it should be in the way of a rol-ler (Z1x37 when it was descending, the spring returning the free end portion of the actuator to norma] position when permitted to do so.

The free end of the actuator is curved and -in the movement of the transferrer from the vposition, Fig. 8, into the position, Fig. 9,

meets the roller d, shownby full lines in lines, it will be noticed that the stud d1 is extended downwardly and has a shape in cross section substantially as represented in Fig. 2. Whenever the heel and to p-lift holding plate l occupies the position shown in ig. 9, which is its position when a heel is to be attached, the stud d1, see Fig. 2,l is caught by an arm cl22 of a s ring-controlled locking device having a tai d2 and pivoted at d24 on' a `be attac ed.

block 25, adjustablycpnneoted by a screw dm' with an arm 12X of the nail-block head. a. The adjustment of the block d provides for varying the position'of the heel and top-lift holding plate el so that the side of the-heel held therein may be properly'positioned with relation to the nailholes in the nail-block.' The nail-block head a9 is also providedA with an ear 10X, see Fi'. 2, having a hole ,'13 in which is received the stem 14:X of an adjustable stop 14 shown in Figs. 8, 9 and 11. l/Vhen the heel and top-lift holding plate el is moved into position to prsent a top-lift to the attaching mec anism an ear e on said plate strikes against one side of the stop 14 to arrest the plate el in proper position. The faces of the stop are eccentric with-relation to its shank 14X and by turning the stop any one' of its faces may be put into osition vto be met by the ear e, conse` uent y varying the position to which' the oldin plate el is moved in presenting a top-lift,'w ereby the proper location of the top-lift with rela- Y tion to the heel may be insured. AThe 'rodf connected with the` heel and top-lift holding plate e' is. operated as provided for in said patent to move automatically the late el into the Eosition, Fig. 8, when a topift is to The vplate e1 has connected with it, by means of suitable dowel pins and a screw 22, two guideway plates e and e. Each of the g'uideway plates e12 and 13' (one being shown in section in Fig. 10) has in it twoT yide to position the back of the-.top-lift, and

I another e21 acts to position-the :back of the rallel grooves; a back gage e2 is pro- 16, the opposite end of which may be hooked mto any one of a series of holes 100 in the plate e10 according to the size of the hee1 0r top-lift that the spring may always act with uniformfpressure against the breast of either the heel or top-lift whatever their size, but

the backward movement of said breast gage The is or may be limited by a stop shown as a Cotter pin `18, adjustable in holes 19 made in the plate e.

The plate el has, as represented, a uide block el", herein represented as of V-s iape, see Fig. 8, theconverging outer edges of the block being represented as undercut, 'said side edges receiving respectively the free ends-of the heel breast gage f10 and the toplift breast gagedf 12. The back gages 21 and e2 have to be a 4usted to adapt them to toplifts and heels o different sizes. AThe Yshank of each of said back gages is providedwith an extension 17 which receives through it one of ltwo like adjusting screws e, el, said screws having their heads rovided with annular grooves and4 sustaine in a bridge el" in such manner that said screws may be rotated in said bridge without, however, being at all Inoved longitudinally, the threads of the screws in engagement with the projection 17 of the back gages putting said back gages into any desiredposition according to the size of the top-lift or heel. The heel and top-lift holding late el, located underneath the breast gagejp12 and the back gage e2", that hold between them the top-lift, has an extension em?, see 8, that acts as a spanker and occupies aposition to cover the nailbloek am when a top-lift is being-,spanked on, but said plate is cut away on the line 'w to leave a space so that the endof a heel applied between the breast gage 1f Q ,and the ack age e21 ma Vcontact witi the upper side o the nail-b o'ck when'the plate em is moved int-o the position, Fig.` 9, to enable a heel to be attached.' l

In operation let it be assumed that the workman ,has turned the nail-transfer'er from its position, Fig. 8, into its osition, Fig. 9, and' that the nail-sustainer as been released to suppl the nail-block with nails, and that when t e transferrer was coming into the position, Fig. 9, the actuator C115 turned the heel and top-lift holding late e on its pivot pin 12, putting the heel olding space of the late e10 over the naileblock so t at the nails eavin he receiver entered the holes in the nail-bloedt.' The nail-block, having been supplied with nails, the workman dotted ldrivers d, common to said returns the nail-transferrer into its normal position, Fig. 8, leaving the plate el locked in the position, Fio'. 9, by the spring-controlled locking device (In, see Fig. 2. In this position the operator'places in the back gage e21 the back end of a heel and permits the breast gage f1 to contact with the breast of the heel, and puts the rear end of a top-lift into the back gage e2, letting the breast gage fm meet the breast of the top-lift. This done, the operator through usual means starts the heeln'ailinfr machine, 'and the die-bed spindle, with the nail-block head a and nail-block al, is lifted, as described, causing the heel restin upon the nail-block to meet and be resse( firmly at its upper end against the en of the sole of the boot or shoe to which the heel is t0, be attached, said boot or shoe being held on any usual jack. After the heel has been compressed' somewhat in the furtherY movement of the machine in usual manner, the atent,lrise in the holes of the nail-block, am acting upon the heads of thenails drive the nails from` the nailfblock through the heel and attach the latter to the sole, but the nails are not full driven, the heads being left protruding su iciently in usual manner to have suanked upon them the top-lift. During this rst rise o the head a the tail C123 of the spring-controlled catchd22 normally held in the position shown in Fig. 2, meets a trip ing device or controller n2, notchedfat n3, an vpiyoted at 'n' on a pro'ection n fixed to the framework, turns sai tripping device about its pivot n into the ine position Fig. 3, and the tail of the catch passes above the tripping device after which the spring 'n4 again returns the trip in device to its normal position. After theliiee has been attached the die-bed spindle descends, and at this time the tail d of the spring-controlled locking device meets the edge of the t'ri ping device or controller, which turns the ocking device d in a direction to release the stud d, extended downwardly from the plate el", letting said plate be moved or swung automaticalbT by the link f* into the position shown Iby Fig. 8 to carry the top-lift into position tobe spanked onto the`heel just attached. The top-lift having been brought in osition to be s anked onto the partially i riven nails, the ie-bed spindle again rises, this second rise occurring without the machine havin Jr stopped since the-irst rise and descent, and

the top-lift is spanked in usuallmanner upon thc-heads of the nails, after which the heads carrying the nail-block anddrivers descend .into their normaL or starting position, and

the machine is automatically stopped in 'usual manner all ready to repeat the eration, as described. During the seront de scent the stud il of the heel and top-lift holding plate el? is not in position to be held 'by the spring-controlled iocking device or that the nails sup orted thereby ma catch (Z22, and said catch is-moved, as before described, but without producing anyvresult.
