. Specification of Letters Patent. Patented Aug. 1911.

Original application filed August 15, 1903, Seria1 No. 169,643, Divide'd and this application filed lulysll, 1910. Serial No. 571,360.

To all whom it may concerns 7 Be it known. that I, ARTHUR BATES, a

subject'of the King of England, residing at Leicester, Leicestershire, England, have in- .vented certain Improvements inv Machines "for Inserting Nails in Heels, 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 inserting nails in heels.

While. the invention is shown embodied in a machine for attaching heels by nails driven from within the shoe, it'will be .Ob-

'VlOI1S- from the following descriptionv that many features may be used in other types example, it is believed that heretofore a gang-of tools has never been employed in a machine for operating upon heels as an element of the combination which includes oppositely disposed'work engaging members, one of which comprises an apertured platewith a work engaging face arranged to be sustalned at can inclination to the path of movement of the tools,.all of said tools heing'inclined in the same general direction I of machines for operating on heels. For 20' fromnormals to the work engaging face of.

I said plate at the points at which the paths of the tools intersect said face. I It will be understood that the present emb'odiment is shown by way of example and that. the invention is not restricted tothis embodiment except as indicated by th terms of the appended claims.

' According to an important feature of-the present invention the nails requiredto attach a heel completely to the heel seat of a shoe are driven into the heel, inclined longitudinally ofthe heel with relation to the 'surfacewhich they. first enter, An advantage incident to the insertion of'the nails in inanails' tobe madeamoiesimple iglmstruction and more reliable and durable in operation than where the nails are driven in non-parallel paths, as has heretoforebeen. proposed and practiced. 7111 the present embodimentzof-the foregoing feature, a nail.

block or other device having driver passages and a work engaging. surface is provided, the driver :passages being parallel and. in-

tersecting said surface at a uniform-inclina tion. The outlet ends of said passages" lie in a plane, and the nail engaging ends of the drivers operating in said passages are in a plane parallel to theplane of the out- -lets. The drivers are preferably of a'uni- "formlength to facilitate replacement in case of fracture. To this end the drivers are secured to a driver plate having a driver carrying face oblique ;to the drivers and parallel to their nail engaging ends In order to hold the Work under pressure while-the nails are being driven, there is provided a work engaging member between which and the nail block the work is held. Preliminary to driving the nails said member and'nail blockare moved relatively to subject the work to pressure, this relative movement being preferably in ;a direction parallel to the driver passages. In the present-embodiment the work engaging member referred to is stationary and the nail block is moved toward said member to subject the work to pressure. I

A further feature-of the invention consists in -mechanism for inserting heel attaching nails so constructed and arrangedthat the angleof inclination at which the nails are driven into the work may-be varied to suit different conditions. This result is secured in the machine sho'wn'z'by Constructing the nail block so that, the inclination of its work" engaging face rela-f t'ively to the driver passages maybe varied, the direction of said driver passages remaining unchanged. To accommodate change in inclination of theface of the nail block the drivers: may be so arranged that they 'may be-adjusted in position to main tain their nail engaging, ends in a plane parallel with the; plane? of the outlets of the driver passages. Thewconstruotiohlmay befl conveniently such that the-drivers are ad justed together, rather. than separately. Preferably adjustment or the drivers in ac-' cordance with the PfiSifiOIfldf'thB work engaging face of the nail block is insured by so arranging the parts that adjustment of the nail block causes a proper adjustment of the drivers.

In the embodiment of the invention illustrated the nail block is. mounted upon a head arranged for movement toward and from a Work engaging-member adapted to resist pressure applied tothe work. A. driver carrying plunger is arranged for recranged as to permit movement ofthe'nail block toward the cooperatingvwork engaging -or pressure resisting member without caus-' ing movement of the drivers relatively to the nail block toward the work.

In the machine herein illustrated the heel attaching nails are driven from within the shoe and the nail block is accordingly formed and arranged-to enter a shoe. 'The nail block. is secured upon a shoe support -or jack, mounted for movement upon the head into and out of operative posltion to facilitate application and removal of the shoe. The driver carrying plunger is arranged within the shoe support, and the actuating mechanism. for said plunger is constructed and arranged to accommodate movement of said support into and out of operative position.

Other features of the invention 'will be hereinafter described and referred to in the appended claims.

The advantages above. pointed out and others incident to the invention will be best. understood and ap reciated from the following description 0 a preferred embodiment, thereof selected for purposes of illustration and shown in the accompanying drawings in h v Fiure 1 'i-s'a front; elevation of a heel attac in'g' machine embodying the present invention; Fig. 2 is a view in side elevation of the machine shown in Fig. 1; Fig. 3 is a side elevation partly in section'of the jack post and drivers; Fig. '4 tea similar view taken at right angles to Fig. 3; Fig. 5 is "a lan view of the adjustable work support; ig.

The machine illustrated inithe' drawings is of the general type disclosed in United StatesLetters Patent No. 446,885 granted February 24, 18%)1 on an application of J,

H. Pope and in co pending, applicatiqiii 7, the lowerend of which. is pivoted-at S to a lower cross-piece 9 guided in ways formed in the lower portion ofthe frame2f, To the cross piece 9 are secured the 'u wardly extending'rods. 31 connected at their upper ends by a cross-head 32. A stationary cross-bar 34 is rigidly mounted in the forward part of the frame and is provided with bearings through-which the rods- 31 may be reciprocated. The bar 34 actsas an abutment or pressure resisting member against which the heel blank is compressed on the elevation of the jack, as will behere' inafter explained and it may be slopedfor' shaped in any convenient manner according -to the requirements of the work.- Upon the" under side of this cross-bar are arranged heel-holding clamps 35 in'which he liel th be attached may be'placed.

Upon the front of the frame is formedfa block or projection 46 and above this prof" jection is arranged a vertically movablef block 48 adapted to reciprocate in guides formed in the sides ofithe frame and re ferred to hereinafter as the jack carriage support. On the top of the block 48 is sup ported the lower end of a verticalljack" screw 54, the upper end of which is threaded mto a head shown as a jack carriage 56 having ways formed on its'upper side in" which the jack 60 is adapted to .slide'for-i wardly and rearwardly. The jack screw 54 is preferably formed with a pinion on itslower end and may be rotated from a treadle 61 suitably connected with a rack 62 meshing with the pinion, as in the construction shown in said patent abovementioned.

The jack 60 may ,be pulled" forwardly in the ways on the carriage 56 to receivea shoe preparatory to the attaching operation and.

then pushed back into nailin'gfl-p'osition. After the jack has. been positioned hori zontally it is elevated to bfin'gtheiheel seat of the sole against a -heel held'=underl-the cross bar 34. Thismovernent 'isefiected manually by "the operator by, rotating the jack screw 54 through the treadle361 which moves the jack carriage-56. fipwardlx away from-the jack carriage support rec ' carriagethrough.mechanism comprising a ma says ,Bfbiefl-th nailing operation takes place i jack is given a further slight upward ement' which serves to place the heel "heel seat of the sole under a positive I i -This operation is effected autody elevating the jack carriage support4' bo ily with the-jack screw and jack shaft 69 journaled in the stationary block 46 ('Fig;2) 'anda similar shaft 70 journaled inthe-Inovableblock or jack carriage support said. shafts having secured to them respectively, ca-ms 71 and 72, as shown in Fig. 1. Thefcams are operated from; the

n the cams rock upon each other without imjack and during t is period the attaching. operation takes place. During the last part parting further u Ward movement to the of the revolution of the eccentric the cams are rocked in the opposite direction and the jack screw and jack carriage support 48 are lowered sufficiently to release the increased pressure on the heel after which the jack is moved to its lowest position onthe releasewf the treadle 61 which isthereupon swungupwardly by the spring 63 causing the rack'to rotatethe jack screw in the opposite direction and thereby lower the jack carriage to its normal position so that the jack maybe pulled forwardly for the removal of the heeled shoe.

Referring to the construction of the jack and the driving mechanism, which is best shown in- Figs. 3' to 5; reference character 64 indicates a work supporting member which also acts as a nail block and which isflpivoted on a transverse pin 63 extending the block resting atone end on a screw 65 whereby its position may. be adjusted to vary the angle at which the nails are to be driven. H The nail block is provided-with a plurality of short driverpassages 66 arranged in a horseshoe-shaped design extending into the block at a slight inclination to its'workengaging face and having outwardly flaring K ends. Rounded sockets, also with flaring ends, are formed in the under side of the.

nail block corresponding to each of the driver passages and in each of the sockets l I 1s received the upper end ofa tubular nozzle v or driver guide 30 having a guiding pas v sage in which one of the driverslO is arranged to reciprocate. The drivers 10 are actuated by a reciprocatory plunger 50 car ryi'ng the adjus'tably [mounted head or driver block 40. .The driver block 40 is provided with a driver actuating surface having recesses or sockets formed.therein to receive the lower ends of the drivers. The

drivers are connected with the head 40 for independent angular movement relative thereto by ball joints,as shown in Fig.8,

and are retained on the head40 by a perforated cover plate 45. The drivers are guided and maintained in parallel relation and also parallel with the axis of the plunger 50 by the tubes or nozzles 30 the lower endsrofa which are received in recesses formedin theallel relationof the nozzles, block 40 is adjustablyf nounted onaapin 41 parallelto the pin 67 of the block 68 and also to the-journal-pin 63 of. thenail block in order t-hatthe drivers may beuadju'sted to correspond with the adjustment of the nail block and nozzles 3Q-a; The. sockets in the nail block 64 andblock. 68 are so arranged that the diStanCeof-one end ofa nozzle from thefjournalof the nail block shall, in all positions to; which-the nail block'is capable of adjustment, equal the,

from the respectivepivot-pinsto the op.po.-.

site ends of a nozzle are parallel when the nozzles are in place in the sockets.

\Vhen theadjusting screw 65 is rotated to f elevate the nail block 64, it applies a'thrust to the block 68 through the nozzles located to the left of the pivot 63 and-this thrust turns the block .68 about its pivot 67 through the same-angle through which the die block is moved and conversely when the'screw 65 isturned into the post and thedieblock 64 tilted toward the horizontal position by the influence of gravity the nozzles at the right of the pivots swing the block 68 toward a horizontal position in a corresponding inanner. Thenozzlesmaintain their parallel re lationthroughout these adinstmentS although they may have a slight angular movement relative to the'nailblock and block 68. i

It will be noted that the present construc- 5 tion permits the employment of drivers all of the same length regardless of the inclina= tion of the work support, the ends of the drivers being maintained in a plane parallel with the work support by adjusting the driver block 40 about the pivot 41 threadedv into it a bolt 43 which projects through a segmental slot 51 in one fork of the plunger. A leaf spring 52 is attached to the side of the plunger 50 and bears against one end of the lug 42, tending'always to swing the head in a left hand direction about the pivot 41.

When it is desired to adjust the driver block into parallelism with the nail block the plunger may be moved into its highest position and the bolt 43 loosened. Thereupon the spring v52 acting on the lug 42 will force the head 40 to swing upwardly on the right-until it is stopped by coming in con- .tact with a boss 58 formed in the under side of the block 68. The length of the boss or stop is such that it will arrest the upward movement of the driver block40 about the pin 41 in a position wherein the upper face of the block is approximately-parallel with the plane in which the upper ends of the nozz es are located regardless of prior adjustme'nt of the nail block 64 and block 68. The driver block 40' may then be .moved by hand about the pivot pin 41 into a position in which it is exactly parallel with the plane of the upper ends of thenozzles and die block and secured in such position by tightening the bolt 43. By this adjustment o the driver block 40, when the plunger 50 is at the .upper end of its stroke, the drivers 10 are brought to an approximately constant distance from the-upper ends of the nozzles adjusted; and as, moreover, the length of the stroke of the drivers is notaffected by this oblique adjustment of the'nail block and the corresponding adjustment of the driver block 40, the drivers when they arrive at the i '16 of the bell crank lever 15, 16 and the up- L per end of the sliding piece 22 bears against lower limit of their stroke will be at 'a distance below the ends of the nozzles 3Q -un'-"f affected by the adjustment of the nail block.

It will-therefore be seen thatth'efnail receptacles afforded above the upperiends of the drivers in the nozzles have "aisubstantially uniform depth regardless of the various adjustments.

For the pin 50 to the lowerlimit of its travel after each 30 in all positions to which the nail. block is se of'manually raising the plunger 50 and the drivers carried thereby {when it -is pushed rearwardly after receiving a shoe. The actuating mechanism also per mits the plunger 50 and drivers to be elevated manually out of operative relation by the'handle 49,

To the lower end of the plunger is attached a plate 26 extending toward the front of the post and provided with a tubular extension 27 arranged to slide in a guide 28 forming a part of the post 60. The tubular extension 27 contains a spring 29 vheld in position between the bottom of the bore of" the extension and a pin 11 passing through a slot 12 in the upper portion of the extension and fixed in the guide 28. 1 The spring 29 serves to insure the return of the plunger driving operation, the plunger being stopped in itslower position by the engagement of the pin 11 with the upper end of the slot 12.

The shaft 70 journaled in the jack carriage support 48 and oscillated by the verti- 1 cal reciprocation of the right hand rod 31, as hereinbefore described, may be conven: iently utilized in the actuation of the plun ger 50. To this end there is fixed to the shaft 70, which may be termed the driver actuating shaft, a crank arm 13' connected by a link 14 to one end of abell crank lever 15, 16 pivoted upon astud 17 comprising j one of a pair-of studs 17, 18 by which a cover plate 19 is secured upon the front face I of the jack carriage 56. Behind the cover plate 19 and guided partly by a groove 20 formed therein and partly by another groove 21 in the face of the jack carriage is a sliding piece 22, shown in detail in Figs.

8 and 9, 1n which is a hardened roller 23. .The'lower part of the sliding piece 22 is cut away leaving a shoulder 24 through which projectsa portion of the periphery of said roller. The roller rests upon the arm 130 the under side "of the plate 26 which is secured to the bottom of the plunger 50 as already explained; p When the shaft 70 is oscillated in the direction of the arrow shown in Fig. 1 it moves the bell crank lever 15, 16 through the" link 14 swinging the arm of the lever upwardly and elevating the sliding piece 22. 130

The latter acts againstthe plate 26 on the plunger, 50 and forces the plunger upwardly carrying with it the drivers thus eflecting the nailing operation. Movement of the shaft 70 in a direction'opposite to that indicated by the arrow in- Fig. 1 causes the arm 16 of the bell crank lever to move downwardly allowing the sliding piece 22 to descend under the actuation of the spring 29 acting through the plunger,

The arm15 of the bell crank lever 15, 16, or its equivalent, may be connected with the crank arm 13 by a pivotedlink 14 and by disposing this connecting link 14 approximately at right angles to the path of motion of the jack carriage, which path is veras to be negligible. By this construction the '.movement of translation is not interfered with, neither is the bell crank lever 15, 16 moved out of a relation with the arm 13 which permits the instantaneous angular movement of the bell crank lever in response to angular movement of the shaft 70, such movement taking place moreover through an angle which is approximately constant for a given angular movement of the shaft 70, regardless of the vertical position of the jack carriage and the bell crank lever pivoted thereto. This construction constitutes an important feature of the invention in that the length of stroke of the nail drivers 10 imparted by the sliding piece 22 and plunger remains substantially con- ""--\stant in relation to the post and unaffected by the different amounts of vertical adjustment received for different heights of heels. I

The operation of the machine in attaching a heel will be clear from the foregoing description and may be briefly-stated as follows :The nail block and work support 64' is first adjusted to give the work proper inclination to the drivers, nails are inserted in the receptacles and a shoe is then placed over the head of the post 60 with its heel end over the nail block, the. jack being -moved to its forward position. The jack is thereupon pushed rearwardly carrying the shoe under a heel which has been previously Inserted in the clamp under the cross-bar 34 in which position the plate 26 of the driver plunger 50 will be vertically over the upper endof the sliding piece. 22. The operator then depresses .the treadle and elevates the jack carriage 56 by rotating the jack screw until the heel seat of the shoe is'in contact Wltl'l the heel. Power is then applied to the machine by depressing a hand lever which operates the driving clutch as in the machine of said Patent No. 446,885 and the jack carriage support 48 is slightly elevated by the cams 71, 72 thus putting the heel under an increased pressure. Simultaneously the crank arm 13 acting through its connections with the driver plunger forces the drivers upwardly driving the attaching nails away from the surface of the nail block through the heel seat of the sole and obliquely into the heel. After the attaching operation the continued operation of the machine automatically lowers the jack carriage support releasing the increased pressure of the heel and the spring 63 lifts the treadle which,.

through its connection, rotates the jack screw to lower the jack carriage thus moving'the heel out of the clamps and away from thecross-bar 34. The driver plunger 50 has. meanwhile been returned to its lowest position and the operator may pull the jack forwardly to remove-the heeled shoe. Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
