Letters Patent No. 112,155, dated February 28, 1.871.

.aPRovi-:MENT m MACHINES Fon PATCHING. PUNCHING, AND EMBOSSING BUTTON-HOLES OF PAPER-COLLARS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern -Be it known that I, CHARLES LANG, of Jersey City, in the`Sta'te of New Jersey, have invented certain new and useful Improvements in Machinery for Patching, Punching, and Embossing the Button- Holes of Paper-Collars and (Juifs, Yand I hereby de'- Clare that the following is a full, clear, and exact description of the same, `reference `being had to the accompanying drawing making part of this specification.

The object of the present invention'is to greatly simplifyr vand expedite the operation of cutting out the patches used for strengthening the button-holes of paper-collars, pasting them upon the collar, and punching the button-holes, and this is effected by the combination ina machine of mechanical devices, by`

which all of these operations can be performed by a substantially simultaneous operation, thereby very 'inaterially reducing the expense of a very material part of the work in the manufacture of paper collars.

In the accompanying drawingi Figure 1 represents a side elevation of the machine, the legs having been removed.

Figure 2 is a plan viewof the machine, Acertain of the upper parts oi' the mechanism having been removed to expose the top of one oi the dies.

Figure 3 is a vertical central longitudinal section ofthe machine.

' Figure 4 is a rear elevation of the machine.

Figure 5 shows a modification in the construction of the punches.

Adesignates the frame ofthe machine, which may be of any suitable construction. I have shown a table, at the sides of which are uprights, which suppurt the bearings of a inain shaft, C, which shaft derives a rotary motion from any suitable motor, and through which shaft motion is imparted to the sev-l eral parts of the machine.

-B designates a carrier, which is arranged to'slide upon the table portion of the frame.

D D D are punches, and H H H are the dies for said punches. These punches and dies operate together to cut out the patches. A

Within the punches D D D other punches E E E arc arranged, and G G G are the dies for' the same. These latter punches and dies serve to cut, and, when desired, to emboss the button-holes.

The cutting ends of the punches D and E may be formed of pieces of metal separate from their Shanks, and secured therein by any suitable means.

In the drawing each punch and shank is represented as made in one piece,.and is called, in general terms, a punch, and designated by a single letter.

The shanks of the punches D are made square, to

prevent them from turning, and' they slide in boxes E F F, secured to horizontal'bars, which are attached to the framein any suitable manner; or, if of other shape, a slot'or pin, or equivalent mechanical device, may be used topi-event their rotating.

and size to the patches resting againstthe bottom of the punch D, and pressing against a shoulder on said punch E, to raise it after it has been pressed down.

The cxtreme lower end of the punch E is the porperforms the cutting of the buttomhole.

On the shank of said punch E, a suitable distance above its lower end, is a shoulder', 6, which, after the end of the said punch enters the die-G, presses against the patch on the collar and embosses the latter with the device engraved upon the face of die G.

In the drawing a dotted line, to represent stitching, is shown as engraved on the die, for the orna-v mentation of the buttonhole of the-collar.

fIhe shoulder 6 may also be engaged if desired.

This shoulder 6 may be omitted, and the opening in the bottom of the pnnch- .Dbe made to, fit the lower end of the punch Ein which case the punch D, ilrpasting on the patch, will also cmboss-the button-hole without additional mechanism.

A little above each dieH a plate, c, is secured, which plate relieves the punch D ofthe strip of cloth as the former rises.

Upon the main shaft G three doublel cams, I J J, are secured. .The central portions of these cams operate the punches E, and the rims or flanges J J constitute another cam, in two parts, which operates the punch D.

inthe present instance, andin such casetheyare retiacted by springsd, and the punches E are pressed downward by cams I, and retracted by sprlngsf.

or formed on the true arc of a circle struck from'l the centre of said shaft, er nearly so, andthe cam I is so constructed that its largest'radius is at that point, as is clearly shown in g. 3, the effect beingthat the cam J presses the punch D down, which latter carboth, while the projecting portion of the cam I moves the punch E down, which latter cuts the button-hole and embosses 'the collar around the button-hole.`

In some instances I propose touse frames or straps attached to th' punches, within which the cams worlr, thus giving said punches` a positive motion in both directions,v and dispensing with the use of springs.

The machine may bereadily adjusted to operate on collars of different sizes by sliding the outer cams, punches, and dies to or from thecenter. v

To facilitate this operation I have shown the lower. dies Gr as secured by setlscrews,-airanged in slots,

outer punches D D as secured by screws 7 7, in Slots in the horizontal crossbars, in the 'upper part of the 'ame, which permit these .bearings to be shifted to punches and the dies H, which .are attached,these are also adj usted. v The cams are shifted in the usual -way and secured byA keys or set-screws.

0n the shaft C is a crank or eccentric, g, which, by means cfa pitman-rorh'h, and arm t, gives motion to a rock-shaft, j, as seen in ''gsL 1 and 4, and au arm, Je, en the latter, operates the carriage B by means of a connecting-rod, Z, pivoted to saidarm k and to a lug ,on thebottom ot' the carriage.l f

side in the usual manner, are fed from rollers or reels K, and the gummed sideof each is moistened by comingr in contact with a wetting-roller, m, whose periph from revolving in a vat, n, is.. expressed .by a. roller, t, before it comes in contact with the gummed' strip. AI guide-roller, o, will serve to keep'the` strip of cloth iucontact with the wetting-'roller-m; and saidk strip of cloth passes,\preferably, bu'tfnot necessarily,- under a guide-roller, p, and ii'orn thence betweenth'e plate c andI dies H,va,nd"`theuce through'the feedregulating rollers q q. When passing throughjthe latter' rollers it ,is but a iskeleton strip, the `patches being punched out while said vstrip v,is between a When' desired, paste or mucilage may be putin the trough n, insteadof water, and,in such case, ungummed cloth .may be used, and gum applied to it' immediately before it is required for pse, in the saine manner as the wetting, previously described, is effected. n

After the patches have been eut andy applied, the button-holes punched, and the punches raised to repeat' the operation, the feed-rollers q q are rotated, to advance the cloth, by a pawl, 8, which engages with The pawl is operated by the leverlO, (see lig. 1,) which pawl is lifted by a cam,11, secured to a wheel, 12. A weight on the-pawl assists to retract it as well vas lever l0, sqithat the same will be in a position to` rotate the .ratchet-wheel u" the distance of another. tooth. The wheel 12 receives a rotary motion equal in speed to that of shaft O by any suitable means.

In thedrawing, a' pulley, 13, on the' shaft O, is shown,for driving a pulley, 14, of equal size, ou an intermediate shaft, t, and another pulley on shaft t, equal iu size to 12, drivesth'e latter by a belt. It is essentiall that the motion oi' the wheels 1 2 and 14 coincide exactly with that derived from shaft C; so,

in practice, I prefertouse chains, which engage with properly constructed wheels, and thus I avoid all danger of slipping. In other cases effect tins result by the use of gear-wheels. The wheel 12 may4 also be operated directly `froml shaft O by'a chain, o r the pawl-lever 10 may have a motionfderived directly from a cam or eccentric on shaft O,.ariang`ed to give the movement at theproper portion of the revolution, in the salue manner as cam Il. Either a push or pullpawl may be useduto operate the ratchet-wheel u, according to the'arrangelneut of the ratchet-wheel.

. Hinged to therear edge of thecairiage B are. two or more arms, lr, having forked ends, and "straight plates ,`15, are' also attached-tothe carriage.V The collar is laid upon the platesr and l beyond the edge of the carriage B, and slight projections of the plate'on the top ot B prevent the collarr from rising 1 above the edge.

When the carriage B begins to travel forward the collar or culi' is carried between the dies G and H; but before it reaches that position the plates lr' rise upon the high sides of cams s ou shaft t, and are thereby elevated so that the forked-ends strike against the edge of the collar, previously operated upon, and push it oli` into any suitable receptacle.

`When the carriage moves the collar forward Vinto -position between the dies, it comes to rest for a moment,- asbef'ore explained, until the punches operate npon'aud hold lthe collar, at which time the cam s permits the plates lr to fall, and. the carriage is drawnl backward, pulling the said plates from underneath the collar, and bringing theminto position to receive t another collar.` The'strips of cloth, which are gummed upon one The operation of the several parts is as follows: Rotary motionisimparted to the shaft G by the crank 05,01' otherwise, and it revolves in the direction of the arrow. When the carriage is in the position shown the punches are elevated, a collar is. at such time, placed npou't-he .plates lr 15, and, when the carriagel progresses, the collar is carried forward upon them between the dies G G G and H H H, while, atv i the saine time, the finished collar is pushed away, 'as kbefore. explained. At or a little before this time the feed-rollers q are revolved, and thereby bring fresh.

portions of the wetted gummed cloth under the punches.

' Bytherevolutiou of the shaftG the cams J .T now begin to press .upon the punches D, which latter descend upoii the cloth, and, in connection with dies H, cut out the patches and carry them down and paste them upon the collar. 'The cams J remain' in thatposition until the cams I press'down the punches E,

'which cut the button-holes, and, when desired, enr-- tbossth'e collar .or cu around the same with the de* sign on the dies G. Meanwhile, the plates fr have droppeddown and the carriage has vcommenced its rcl turii for another collar.

The punches now rise, the plates b pull the collar '0E the punch E, and the platescstrip the cloth oli" D. The carriage has by this time arrived at its first position, where it remainsjat rest for a moment, to permit anew collar lto be placedl upon r and 15, and the operation is repeated.

It is evident that rectangular or other shaped pieces of paper may be fed into the machine, and afterward cut into collars of the desired shape. Se, also, asheet of paper may be fed between the dies by rollers simlilar to q q, and the button-holesbe patched, punched,

and embossed on such paper at intervals, the collar being afterward cut out by another operation.

It will be observed that, by the mechanism described, the collar or cuff, or the paper from which it is to be made, is broughtinto position, and the patches are cut, pasted on the article, and the button-holes cut and embossed, 'all in one 'continuons and nearly simultaneous operation in the same machine.

It is also evident that this machine may be 'used for patching, cutting the button-holes in, and embossing paper cuffs, by simply regulating thenumber and adjusting, the punches, and dies, and carriers.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The method of cutting out and applying the strengthening patches to paper collars and cuis, and cutting or punching therein the button-holes, substantially as herein specified, that is to say, by first cutting out the patch, then pasting it upon the co1- lar, and then cutting or punching the button-hole in both patch and collar, the entire operation being effected by one forward .travel of the punches,and by a practically simultaneous operation;

2. The combination of the punch and die D and H with the punch and 'die E and G, and mechanism for operating the same in rapid succession, for cutting out the patch and pasting it upon the lcollar and vcutting the button-hole in both patch and collar,.substantiallyi as herein specified.

3. In a machine for cutting the button-holes in and applying the patches to paper collars, the combination, with the punches -D and' E, of the' cams I J, mounted -on the shaft C, and arranged and operating lsubstan tially as and for the purposes herein specified.
