IMPROVEMENT IN MACHINES FOR PUNCHING AND EYELEdilNG SHOES, &c.

Specification formiig'part of Letters Patent No. 37,170, dated December 16,1862; Reissue No. 2.335, dated August 14, 1866.

To all whom 'it may concern:

Be it known that JEREMTAH KEITH, of New Bedford, in the county of Bristol and State of Massachusetts, invented an lm proved Eyeleting and Punching Machine; land I, Emi/IER` V TOWNSEND,of Boston,as aforesaid, (assignee,)

do hereby declare that the following, taken in connection with the drawings which accompany andform part'of this specification, isa description of his invention sufficient to enable those skilled in the art to practice it.

The primary object of this invention is to obtain a machine for setting or clinching eyer lets in stock, (such, for instance, as boots and shoes iin-which the eyelets taken ntrema pro'- miscuous collection may be lsuccessively and automatically presented to thev actionof the clinching-tools. v Prior to this invention there had been, so far as" is known to theinventor, no mechanism which effected th is result,thougl1 a machine had been devisedin which theeyelets were arranged or threaded in regular or eyelets are thrown together into a box or magazine without regard to their positionsand from this' magazine they emerge in upright positionsy through an opening or openingseonstructed'to allow them to passwhen, and only when, in proper positions and this feature constitutes one portion of the'invention. l

In order to have a succession of eyelets properly and constantly presented for thesuccessive actions of the setting-tools, and to remove the setting-tools from too close proximity to theeyelet-m agazine to allow the convenient introduction of the stock` to be eyeleted, it

4was found desirable to employ an inclined conductor or chute leading fromt-he magazine to a point near to, andin', or aboutin a horizontal plane with theA sets; and such a device is employed in this invention, it being so arranged to operate,in combination with the magazine, that itfis kept vcharged with eyelets, which slide down through it, the lcwermost one being always in position to be taken by the clinching-tools. This constitutes another portion of"the invention.

To facilitate the entrance ot' the eyelets into the gates or openings and thence to the chute or conductor, a vibratoryor shaking movement is given, agitating the body ot' eyelets until in their movements they assume upright positions and come opposite to the gates, when they will slip lthrough and slide down the chute. This feature constitutes another portion of the iuventiou With the 'setting or clinehing-tools there is combined a bed and punch for punching the holes for reception oi' the eyelets, this bed and punch being so 'arranged and operated that they are automatically brought into position after each act-ion ct' the setting-tools; and this construction or combination also forms part of the invention. 1 y y To keep thelowermost eyeletin the chutein posit-ion untilseizedfby'the pin of one of the settin g-tools, a detainer'orjdetai ni ng-surface is employed, which detains the eyelet at the bottom of the chutejgbut yields .to allow its exitvwhen 4the said pin enters it; and such device forms another part of the invention. A

In connection with the chute or magazine aud clinching mechanism, it is desirable to employ a yielding pin upon the setting-tool, which takes the eyelet from the chute, said pin hold- 'ing the eyelet in position until the upsetting- 4tool comes down upon it, and yielding to the` pressure oi said uppersetting-tool; and this combination is also of lny invention.

The drawings represent a machine embodying the invention, Y l

' 1ig-ures l and 2 showing side elevations of the same; Fig. 3, a top view with the covers of the maga-zine and magazine-box thrown 'back` Fig. 4 is a vertical transverse section taken through the eyelet-magazine. Fig. 5 is a,` vertical and longitudinal section taken throughthe punching and setting tools.' Fig.

6 is a front elevation. of the machine; Fig. 7, a section of the eyelet-magazine, showing the exit-gates in elevation` A denotes a bed or table; B a frame erected thereupon for supporting a magazine or box,

C, for containing the eyelets, which are thrown loosely into it without regard to position. .The Imagazine is inclined, as seen in Fig. 5, so as to throw the body of eyelets toward'the front side of the box, and at this side it is provided with one or more gates or passages, g, of such'size and form as to allow7 the eyelets to slip through the box when, and only when', they are in upright position. l

From this magazine, if thc mechanism be not so arranged as that the eyelets shall pass from the magazine directly upon the 'pin ot one of the setting tools, an inclined hopper, D, leads, the gates g opening from the maga.- zine into the chute, and the chute extending down to a point where the settingtools may take the lowermost eyelet properly presented at the end ot' the chute; rlhis chute is so constructed that the eyelets are kept in line and in upright position, -while they slide freely by the action'lof gravity from the magazine to the lower end of the chute.

To agitate the body ot' eyelets in` the magazine soas to cause them to constantly' change position until, in assuming upright positions, they slip through the gates g, the magazine has a vibratingfir-,reciprocating shaking movement given to it, the mechanism shown for imparting said movement being as follows: The magazine is supported on a platform, b, which may be so arranged as to be capable ot' a tilting or rocking movement, and this platform has an opening` init, through which a ,stud projects, as seen in Figs. 1 and 5. Be I low the platform is a dog-plate, b2, rocking on a pivot, e, and haying on its periphery one or more dogs or teeth, o. This plate is jointed yby a connecting rodJ, to a tre-aille or other leveg, through which the setting and punching tools are operated, thc plate b2 thereby receiving a rocking movement, and one ofthe teeth o striking the stud projecting' from the magazine at each movement of the rod, thus giving a reciprocating-lateral movement to the in agazine and agitating the eyelets, as will be readily understood. v f

The setting or clinching tools are seen at S and K. The lower one, S,v is shown as havin a spring-pin, u, .to remove the lowermost eyeletfrom the chute upon one end, and al punch-bed, t, on the other end, the piece S rotating one hundred and eighty degrees at propel` times to bring eitherend up. The upper tool or piece, K, has on one end a punch, L, co-operating with the bed t, and on the other an upsetter, l, which clinehes the eyelets.

against the anvil end of the piece S, carrying the spring-pin u, saidl spring-pin yielding as the upsetter comes down upon it, and thus allowing theeyelet to be clinched in the stock. The pieces S and K both rotate verticallyin the vertical plane with the center ot' the chute, and the constructioll and arrangement of the lower piece with relation to the chute is such 'The upper tool, K, is tixed or. a shaft, '12,'

which turns in the bearings in i|e end of a forked bar, I, mounted on the top of a vertical slide-rods ll, jointed to a bar, QP, by depression and elevation of which the mechanism is operated.

One end'ot theshat't carries a friction-wheel,

N, whieh'at propertimes is impinged upon by a presser-bar, '0, sliding out from a stationary frame, l, to which it is connected by sliderods p. Iny the frame P is a toggle joint, Q, the arms of which extend across the trame,

one of them projecting through and abut-ting against or being connected to the presser-bar O, as seen in Figs. 2 and 5. rlhis toggle is actuated by a vertical bar, S, which bears two studs or projections, 1'1", said bar being atixed to thel barl. i When the rod H is depressed the upperstnd, r, strikes the top of the toggle and straightens its arms, forcing the bar O outward, and `carrying the friction-surface, of said bar againstthe surface ot' the frictionwheel N, this bar O beingmoughened on its surface, or provided with rubber or similar material, to produce rotation of the friction1wheel asthe har H rises. When this contact is produced t-he ascent of' the bar l causesthe wheel N to rotate one hundred and eighty degrees, reversing the position ot" the punch yL and upsetter l, thelower stud, after such reversal,

striking the toggle and throwing its arms out 'ot' line andthe presser-bar out et' contact with the wheel, where it remains until the two setting or punching tools have next operated together, the upper stud el'ectiugthe contafct again and again, causing thereversal of the tools as vthe bar H next ascends.

To determine Vthe position of the punch or upsetting-tool, or to stop its further rotation when it has come into a. vertical position,'one

end ot' the shaft m carries a wheel, MV, having two opposite notches, into which the tooth of a spring-pawl, n, slips when eitherend ofthe tooth -K comes into vertical position. This paivl is tripped by a catch, o, Xed to the table A, as the bar I descends,-perinittingthewheel- N to be rotated until the spring ou the pawl carries the pawl-tooth into` the opposite notch in HIE-wheel M. Similar semi-rotation is imparted to the under tool, S, to bring its co-operative end into position for the action of the punch or upsetter, as follows: 'The tool S is vmounted on a shaft, T, turningv in bearings in the stationary frame R'. One end of this shaft scarries a gear, U, into which a pinion, V,

meshes, which pinion is driven by a pawl, w',

on a lever, W, jointed by aconnecting-rod, X, to a bar, Q2, which is ixed to and moves with the har Q2, which actuates the slide-rod H, be ing forced down by a treadle-lever or other y -a pawl, a', engages.

wise, and carried upward by a spring, P2. The

opposite end of the shaft T carries a notched-` wheel, Z, into the notches of which a toothon To disengage the pawl from the wheel Z, to allow said wheel .to bel turned one hundred and eighty degrees, the barQ2 carries a tripper, A', which, striking the adjacent end of the pawl-lever as the rod H ascends, releases the Wheel from the pawll eyelet, accordingly as the punching or setting tools are alternately and successively brought into position.

Tile lower end. of the eyelet-chute is provided with a yielding detainer, E, consisting of a flexible spring or springs, or other equivalent material, so attached to the chute as to extend into the patl of the eyelets to stop the lowermost e'yelet in position for the pin a in its rotative movement to enter said eyelet and carry it into position ``to be clinched, as before explained, the dctainer yicldin g to allow 4the passage ol' the c yiciet-,and springing Vbtu-clitostop the next descending eyclet in the chute.

From this description the operation of the machine in punching the stock, in automati-` cally bringing the eyelets into position, and in clinching them, will be readily understood without further elucidation. f

It will be obvious that an inclined eyeletmagazine may be employed, in combination with the setting-tools, Without the inclined chute, the spring-pin on --the anvil-set taking the eyelet directly from a gage opening or openings in the magazine, instead of from the end of the chute; but such an arrangement, though practicable, is not deemed soprae'tical as an organization having the chute interposed between the magazine and setting-tools, such organization insuring a succession or column of properly-disposed eyelets, which slide down the chute and come into position by the action .of gravity'. i

1t will also, be lobvious that the employment ofthe punching-tools may be dispensed with and only the setting-tools used, in which case the' upper tool will need to have only the verticalmotion to clinch the eyelet, and the lower tool only a lateral or rotary 'motion sufficient to take the eyelet from the chute for from they magazine and l'lori-ng it into positionffor the-` action of the upsetting-tool.

'What is claimed is- 1 rlhe combination, with eyelet setting or clinehin g tools, of a magazine in which the eyelets a re loosely contained, but from which they emerge in upright position for the action of the setting-tools.

2. The combination, with an eyelet-magazine and eyelet elinching tools, of an interposed chute or conductor into which the upright eye; lets emerge from the magazine, and by which each in succession is conveyed to position to be seized by the pin of one of the setting-tools. 3. A construction by which the eyelets in the magazine are agitated to cause them to assume positions in which they may emerge from the magazine. v 4. So constructing thelower end ofthe chute that each lowermost eyclet is detained in position until removed by the eyelet-pin.

-- Gombining-withzan automatic eyelet presenting. and setting mechanism an automaticl punching mechanism operating inthe same vertical line of operation with the-,oliuching mechanism.

6. Combining with the mechanism which brings each. eyelet into position before the clinching mechanism a yielding pin' projecting from the anvil-set, said pin receiving the eyelet and holdingitn position for the descent of the upsetting-tool and yieldingto the pressure of said upsetting-tool or the pin projecting therefrom.

In witness whereof I have hereunto set my hand this 5th day of February, A. D. 1866.
