Application and Beamter' 2s, 1897. serial-No.' 664.028. (No mhdelJ To @ZZ kwhom it 71mg/ concern:

Be it known that I, WILLIAM HENRY 4Don- MAN, a subject of the Queen of Great Britain, residing at Staiord, England, ha'VeJnvented new and'useful Improvements in Nailing and Lasti'n g Machines for Shoes, (for vwhich I have obtained a patent in Great Britain, 'No.'23,363, dated December 6, 1895,) ot'which the following` is a specification.

' My invention is for improvements in machinesfor putting nails of various sizes into shoes, from hobnails to lasting tingles or tacks; and it consists of the lfollowing fea tures-that is to say:

Theftacks are put into a hopper and pass from it delwn a chute. At'the termination of the chute is placed a reciprocating lnail-carrier consisting of au arm which makes a semirevolution about -a pivot and' each time takes a nail from the end of the chute and carries :it around until it is just under the hammer. There arc suitable shutters actuated at suit-' able times which respectively shut .up the end ofthe chute when the carrier leaves it and shut the nail into the carrier. nail arrives underneath the hammer, the carrier stops, and the hammer, which is magnetized, descend'sclo'se to the head of the nail,

which is attracted to it, and immediately rises again, liftingthe `adhering nail'clearout of the carrier, which at once returns to fetch an- -other'naiL As soon as the carrier is outlof the Way the hammer descends, with the nail', and drives it into the shoe, which is held in a suitable position below. r A

I employvarious gages for determining the position of the' shoe while in the machi`ne+n an edge-gage, against which the edge of 'the boot rests. edge of the sole 'or sometimes the corner formed where the upper loverlaps the insole, or, again, it may be the feather of the boot, or eventhe edge ofthe top piec.. 'This edge-gage overlies the edge, so as to form a ledge against which the boot can be pressed upward vand has a: face more or less at right angles to' it', lagainst which the .boot may be pressed sidewise, and is made of 'diderent shapes and isadjustable in. different directions to suit the different kinds of Work'tol be' done.- -Itis sometimes used- `fixed and Sometimes is allowed to' slide inan'd out underthe This edge may sometimes be the control of'la spring and-is locked faistjustbe fore and during the time the upper is being pulled'upli'ffthe boot is being lasted) and the "nail is beingput in. A gage is also used against whichthe side of the boot rests. This' gage is on aslide and under-the controlof a,

`spring and is .lo'cked at the necessarytimes. A gage is occasionally used that takes into'the y channel onth'e insole anduassistsuin vguiding 'j the work; also, a gage that takesgonto the surg y face'of the sole or insole and assists in determining the angle at which the boot ispresent ed to the machine. Thesegages (are adjustable and may be used/fixed orwith a slight, '4 duly-timed lifting movement to facilitate the movement of the shoe.

The surface gage is sometimes required t`o have inaddition an up-and-down-movement governed-by a spring, and saidgage is locked 'at the requisite times.

Thev g'ages are not allv necessarily employed at one time, but are madeuse of as occasionl may require .to suit the various kindsoffwork to, be done. f

The boot iscarried upon a framef commonly l f known as a jack,? of whihthere aremany varieties in use. The jack is supported upon a post whichfrests in afhookl-joint.npona treadle or lever, by `means` of whichfthe boot is held up against the gages abovementioned U with sucli a degree Tof force asfmay bedesired and by means of whichit maybe readily disengaged when, the` operation "iscompleted The jack sometimes has a slightnpfanddown movement, orat leastthe boot is. periodically Y.

released from pressure ,againstl the gages,l so that its movement'lnay be' ij'acilitated.;v 5x1 g l My'invention also consists, Yin, conjunction with the above, of a pair of mechanical .pin-

cers actuated bythe machine, which is used i to lyhold of and drawthe upperfiover the last; The'- pincers are adapted togrip different thicknesses of lmaterial and to exert .a degrec of drawing 'strain-upon the upper, varif able at pleasure. The action of the ,pincers locking-bar which is connected to the jack vor 2: .jack-post by a hook-jointand 'passes tslil'mlghv aj'cup and K balll mounted in, the columny ,on

them and bring'the bottom vtack truly vertical and'insnreitsbeing in its'proper position in the notch (111 `before the arm d moves away.

This divider e may be operated by a cam e'. j

` p and the shoe is held up under the hollow and lever e2 from the shaft a2.

For the purpose of sealing the open end of the chute c1 while the arm d is a\vay,' I provide-another shutter-arm f,-also loose upon the pivot d and having an end like the arm d, but withoutlthe vertical notch du. The arm f lies against thevarm d on the opposite side to the arm d, and when the arm d moves away the -arm ffollows it, moved by the pressure of the spring f' into the place just vacated by thearm (l and shuts the end of the chute c1, until pushed away again by the returning arm d.

So that the bootmay be properly presented relatively to the hammer b' and other parts, I provide an edge-gage g, which has a horizontal notch g', against which the edge or cor- 'nerwhere the upper turnsover on the insole inay be pressed vby the operator and which furnishes a-guide for him in feeding along the boot.A This gage g may be used fixed and made adjustable vertically and horizontally or it may be mounted upon a slide g2, carried lin the frame a and held forward bya spring g3, being retained in any position to which the operator' may have pushed it while m'a- V'nipulating the boot by a ratchet-wheel g1 and pawl g5, connected by a pinion -g6 and rackg7 -with the slide g2, the pawl being unlockedat suitable times by the operation of the machine,y

the arrangementv somewhat resembling that described in the specification of a'British patent grantedI to ine, No. 11,437, A. D. 1895. I may providealso a gage h, which is similarlyT mounted and operated, having a spring h' which bears it forward against the upper, yielding wheny the operator presses upon the boot, the gageV being locked by the machine previously to the driving of each tack, and, if

desired, before the gripping movement of the pincers, hereinafter described, takes place, bythe operation of a camhz, which is mounted ou the sbatte2 and'acts on a roll h3 and lever.

h4, .mounted ona' pivot h5 in the frame a', the lever being jointed to a rod h6, which carries an arm hl, engaging ay lever hs, mounted on a shaft h9 in the iframe a', the shaft h1 also carrying a pawl hm, which engages vthe teeth of a ratchet-wheel 7111. The ratchet-wheel h11ismoun'ted'on a shaft k12, alsov carried in the f-ramelva and having mounted npouit a pinion XL1S, gearing in a rack h11 upon'the slide h15, which is vf'ree to move inthe frame a' and carries the 'j gage -ri.` Th'e movement ofthe surface gage is precisely` similar,jbnt`is in a vertical-instead otla horizontal direction and is not illustrated."` j l Oneforrn otsurface gage v'whichis" used in going around the seat ofthe heelis illustrated in Figs, 22jand`23. v It is mounted beneath the portion'a. of the frameon 'a'pivotpand stands when iri'use in the positionfpf," .being held against the stop p2 by '011B SPF'Ug'Ps! When turned horizontally, so as to be out of use, into the position p4, it lies against the stop p5. The tacks are driven through the hole p7 against the teeth ps. The handle p1 is for turning the gage into or out of position.

When it is desired to give to any of the gages a slight duly-timed lifting movementto facilitate the movement of the shoe, the arrangement is the same in principle as that described in the specification of a British patent granted to C. F. Gardner, No. 2,591, A. D. 1885, and therein illustrated in Figs. 2, 3, and 15 for giving a movement to the horn N.

To pullthe upper over onto the insole, l provide pincers actuated bythe machine and in one form, as shown in Figs. 15 and 1 7, constructed as follows: A shaft t' is carried in the frame'a7 and'operates, through'gears 'i' i2 is 54, a shaft i5, which is also carried in the frame a7 and carries a cam 1', which operates at the proper time between the arms i7 i8 of the pinces, so as to open'the jaws 9.10 about the pivot '511, which jaws are afterward closed upon the edge of the upper by the spring 12. The pivot @'11 is carried by an arm/13, which hangs from another pivot 14 in the frame a7. A second camv @'15 on the shaft i5 acts upon a roll 16, mounted on the arm i1", so as to swing the pincers in at the proper times toward the machine against the tension ofa spring i", which is carried by an arm @'18 of the frame 0.7, andvwhen released by the cam '1115 the arm @'11 is pulled outward by the spring i, so as to draw the upper, which has been previously gripped by the jaws if' @'10, over the edge of the last .'zz'and insole This arrangement may be reversed and the cams made to close and pull on the pincers', while the springs open the jaws and return the pincers after the pull. Another construction ofpincers is that shown in Fig. 7, in' which I provide 'avertic'al bar j,

IIO

which carries at its .lower end the lower jaw j of the pincers and is retained vin place by an upper eyepiece 3'2, mounted o n its pivotj3 in the-frame a', and by a' lower eyepiece 7"1, carried by its stein ji in a slot j6, 'also in the frame a. I A set-screw jl allows of the bar j being set up and down in the eyepieces jg and f1. A face-cam js on the shaft n.2 acts' upon a roll j, retained upon the bar j by collars 3'10 j, so as to move the jaw j inward, and a spring j12- serves to move it outward. v The upper jaw 3'1"" of the pincers is mounted on a pivot L7'1" in the lower jaw j and is operated by an edge-cam j15, which acts on a rollj16 and lever j", whichis mountedonv a pivot j13iu j@ to a rod jfzo'and link jm, connected to thel pincer-lever j. The jawj'is closed upon adjusting-screw j, against which the bar j takes. Aspringf'topens the jawj3 when released `by t'he cam j?.

In the form of `pincers illustrated lin Figs. l and 2 the cam 7'25 opens 'the pincers-jaws, while the springj26 closes them when released. The presser-foot'illustrated in Fig. 8 and which may be -used i'n'lien of pincers is for the same purpose as and acts in a similar manner to that described' in the specication of-a British A. D. 1895.

If the machine is intended to luse either ot' two lengths of tack at will, two cylindersand chutes are employed,the arrangement being very similar to that described in the specification of aformer British patent granted to me, No. 18,374, A, D. -1894.. The operator by' means yof a handle 7c(see Figs. 15 and 16).and quadrantk', 4mounted on av pivot k2. in the frame a', slides' the rack k3, *frame 47a4, and

cylinders 105106 to theright'or left, according` `asile-wishes to bringeither' the one or the other fof the chutes k7 ksinto position to supply tacks to the tack-carrier. v j y T o prevent the tacks running out vof `the ends of the chutes la7 las lwhen removed 4from, opposite the carrier, I 'provide ahorizon-tal Hat-sided bar l, Figs. 15,16, 18, yand 19, against which the 'ends' of the chutes slide vand by.

which the open ends of the chutes are sealed.

This bar is-a xture and has anarrow cross slot ZV formed -in it for the passage' of the ,tacks just where the carrier operates, and a hollow Z2 isformed in one side of the bar Z,

having lthe same radiusof curvature as the' end of the carrier-arm d, so that 'the latter can enterand leave properly; When a chute, as k7, is placed exactly coinciding with the slot`l,.thevtacks canpass'to the carrier; but 1n all other positions the chutesk7 ks are sealed by the flat side of the bar l. The boot and lastV may be carried upon a Jack, whlch maybe of any suitable construcition, or maybe held to the machine-by hand.

. In order-that the pulling action of the pincers may nothaveto be resisted by the operator, 'I provide an arrangement which locks the jack'immovably in any position in wh ich the operator chooses to -place it priorto the action of the pincers and hammer taking place. VThe jack m, Figs. 1 and 2, is mounted on .a post m', carried by a hook-joint m2 ona treadle-lever 'm3,' which is mounted on a pivot m in the columna, and the whole is balanced byla weight m5. Theupper portion Im6 of the 'jack rm. is free to be turned around upon the lower portion m", and a wheel ma is providcdon the portion m6 and turns with it.

lhe wheelmgears into av pinion m, which 1s mounted on a shaft m10, carriedin the portion mi of the jack andconnected by a second hook-.joint 'r/ to a shaftml, (see also Figs. 3, 4, and 9,) which passes through a split ball 'm1s in the column a. The split ball m13 is carried in a pair of cups, the one, m, being. fixed to the column a and the other, m15., be-A patent granted tome, No. 7,494,

ing'provided with a stem m", which passes out .through the column .side and is acted upon bya locking-lever m1?, which is piyoted on a pin m1? to the column a and drawn'inward by springs m19, so as togrip fast the cups on Ym15 upon the split ball 'm13 and the ball 'upon the shaft m12, so that the latter can 'neither revolve, swing, nor slide andthe jack .bef

comes immovably fixed. The jack is un; locked by the action of the cam h2 and rodjt, described in'connection with the gage 7L. The' :rod hi is jointed to a lever m2, mounted-.on a

vvpivot m21 -in the column a,its end m22, when thru'st dow-n by the rod'h, taking on the l`ock= ing-1ever m17 and thrusting the same outwardl against the resistance of lthe springs mi, re" leasing the cups mum and ball 711,13, so as to leave the shaft m'free either torevolve when 'the jack isrevolved, swing whenl-the jack is swung sidewise, or slide when the jack 'is moved to or from the column.

If' the machine is intended to be used for drivingvnails into soles or top' pieces either 'forati-aching themto the boot or for'increasq. ing the wearing properties thereof, .the aforo# .said or other suitable Vjack may sometimes be 'used or a horn or stump may be employed inanyfusual manner.V During .the feeding movement of the work, which may be performed `by 'an awl in a manner/somewhat similar to that-described in the specilcation of a British pateut granted to nie, No. 17 ,407,J

A. D. 1894, the'jack or horn mayibeadrawn down by a camandJratchet movement like that described in the specification of the said British patent` granted to 0. F; Gardner, No.`

.2,591, A. D. 1885, and already referred to. The pincers are dispensed with, as may also be-tliejack-locking arrangement. 4The gages which bear upon the edgeof either thesole loo or the toppi'ece to regggulate"thel distance ih ns gives a'to-and-fro'feeding movement tothe slide n, which is mount-odin the imain frame a and carries the aforesaid slide lna. The

magnetized hammer b is operated, as before v described, by the cam `b, and the cylinder c', chute c, and nail-carrier all operate as a1- ready explained. The magnetized hammer b' carries down the adhering nail vthrough a split nose-piece o, which centers the nail and .opens to allow of the passage of the nailhead,

the nose-piece o being carried upon a lever o', which is mounted on a pivot o2 in the framea.

. and is operated so as to move to and frofunder thehammer and away from the advancingzawl n4 by the cam 03 upon the shaft a2.

The 'specific' construction of the jack or work-support is not herein claimed, but will form 'the subject-matter of another lapplication. 4
