' BUTroNnOLE- UTTING MACHINE.
To all whom it may concern:
Be it lmown thatwe, Henry SILVERBERG and CLARENCE VTQBUR GE R, citizens of the United States, residingatgWashington, in the District of Columbia, have invented certain new and useful Improvements in Buttonhole-Cutting' Machines, of which the fol- I lowing is a specification.
This invention relates to machines for cutting buttonholesin garments during the process of manufacturing, and is particularly applicable to cutting buttonholes along the front edge of coats.
l-ieretoforesuch buttonholes have been cut one at a time'by hand, a special punch. or cutter being used, and great care on the part of the operator was necessary to insure uniform spacing of the holes, both from each other and from the edge of the garment. The proper locating of the buttonholes by this method consumes a large amount of time and necessitates painstaking measurements and moreover, the results are not always as accurate as might be desired.
It is the primary object of the present invention, therefore, to provide a machine having a series of cutters which can be operated simultaneously so as to cut an entire row of holes at a single'stroke and to provide meanswhereby the cutters may be uniformly and accurately set at different distances apart, correspondingwith the size and nature of the garment. v
.A further object is to providea machine of this character having meansfor cutting; the lapel buttonhole at the same time as the other button holes, and so arranged that the lapel buttonhole may be disposed at any suitable angle required.
Other objects and advantages will appear from: the following description, taken in connection with the accompanying drawings which form a part of this specificatiomand in whichi- F igure- 1 is a front elevation of the 'com plete machine, partsbeing in'section,"

Fig. 11 is a detailed section showing the method of supporting the screw shafts here inafter described; and v ig. 12 is a perspective View 011 an enlarged scale, showing one of the anvils with which the main blades cooperate.
Referring to the drawings in detail, the machine comprisestwo side frames 1, having widespreading feet 2, constituting a base- These side frames .are rigidly conmeans of a pair of bars 3, disposed near the top, and a bar 4 near the bottom. V
On the. bars 3 are mounted a series of cutting devices or mechanisms, designated in their entirety by the reference characters a, b, c, d, e, f. The. cutting device e is fixed, while a, b, c, and d are independently movable, although connected by a mechanism hereinafter described. The cutting device f is movable by means ofimechanism wholly independent of that operatingthe other devices.
Referring to Figs. 5 and 7, one of the cutting devices. such as b, is shown in detail. It comprises a body portion 5, having apair of eyes 6. through which the bars 3 freely pass. At the rear of the body 5 is an upstanding portion 7. carrying at its uper end a pair of spaced eyes 8. Behind the eyes 8 is a horizontally extending lug 9, carrying, an adjustable stop pin 10.
arm 11, pivoted at 12 between the eyes 8,
and provided. with a tailpiece lam-extensive hereinafter 'de,-. scribed. The cutter blade is carriedv by an,
spring 15. which presses against the; lower,; side of the lug 9. This spring, as willbe comprises a lazyt-ongs structure.
underside ofthe evident, serves to maintain the arm in the position shown in Fig. 5, with the underside offthe lug 1 3 in engagement with the end of thestdp pin 10. r
The cutter itself is of the usual form and conprises a blade 16 and heel portion or punch 16. The cutter is preferably set into a dove-tailed or T-shaped block 17, which slides into, a similarly shaped slot in the end: of the arm 11 and is secured in position by means of a set screw 18. An opening 19, extending up through the block and arm 11, permits the escape of'punchings out by the punch 16*". A suitable stripper comprising a leaf spring 20 is preferably secured "tothe arm 11., acent the cutter. These cutters above described cooperate with a rotary anvil 21 (see Fig, This anvil is preferably of hexagonal; form, the faces of which are of progressively decreas: ing lengths, as illustrated at hm, w o. The purpose of this is topermit buttonholes. of different lengths to be cut, as isywell understood in the art. This anvil is provided with a central opening 22, through which a screw 23 passes into the endgof the body 5, the anvil being as above intimated rotatable on such screw so that any desired face may be brought into cooperation with the cutter.
order to shift the cuttin devices (4,1), 0, (Z', along the bar 3, as may e required, I preferably provi lo a screw shaft 24;. journaled at one end in the frame 1, as indicated at 27, and provided with a crank 28 by means QfWlllOll it can be turned:
In shifting the cutting "devices, is, of.
course, essential that a uniform spacing between such devices be maintained. In other, words, while the length of the series,' -or the distance between theffirstand last cuttingdevice may be varied, to correspond with coats ofdiff'erent lengths, all of the devices must, ofcourse, remain the same distance apart. In order to produce this peculiar movement, we have devised the mechanism, shown more particularly in Fig. 2, which mechanism This consists of'a plurality of links 29, each pair of links being pivoted tcgether at their middle, as indicated at 30, and the pairs of links being pivotally connected at their ends by, means f'the'pins 31'. The center pin 30, at
the end of the series, is set into .a block 25, which travels upon the screw 2 while. one of" the intermediate pins 301 carries a supportingblock- I rests loosely upon the screw shaft 2a, The body 50f each of the cutting devices a, Z), 0, (Z,and' e, is provided on its undersidev with a transverse groove 32, in which groove the ends of the pins 3110f the ray tongs struc tur'e freelyslide;
t:;ng-;dev- 'ee'i's fixed. WVhen, scre'wsh- I I I I I I I II sli ing: he e ts nd. exp n s Q e tracts tho-eras the 2 6, which is not threaded, but.
As before stated,'the cut- 2st is'rotated, the block 25 travels the lazy tongs structure, as the case may be, thus shifting the cutting devices a, b, 0, and (Z, simultaneously. Timpani-1m thing about the movement, however, is that all of these devices are shifted unequal distances, thealnou nt of travel of each being directly proportional to its distance from the fixed cutting device 6. Thus the device a has the greatest movement, 6 the next, etc. The. result of this is that as the series of cutting devices is lengthened or shortened, as the lazy tongs structure or contracted, the' distance between'the cutting devices d. ,12 and 0 nd d ant c, r m in n o m t r ugho t the s rie hu n equ l spacing f. e; buttonho e is a sured- T utting. devis fie nt nde for .1

The body 5 of the device f is provided with a central downwardly extending lug 85, which hasa screw-threaded opening en gaging a screw shaft. 34- journaled at one end in thefrarne 1,, as indicatedat, and; p dedv h an perating wa k Thetwcoscrew shafts and; 34 are pref-r erably in alinement, and; arcjtogether rotatably supported in a lug .6" depe the body 5 of' the cutting 'de ic shown in Fig. 11, the sh .ft 24 end 4C9 which is j ournaled in lug 6", while the shaft I into a similarly. shaped socket in theg d of the shaft. 24. "Thus, the shafts 24:

On top of each arm 11 is mounted a clip 50, held in position by a screw and thumb nut 51, and capable of being swung around such screw when the thumb nut iscloosened. The clip 50 is provided with a cup or socket in which is seated a short, stiff helical spring 52, such spring preferably carrying at its upper end a cap 53.
The actuator consists of a beam or bar 54, extending the full length of the machine and disposed directly above the caps 53, which caps are located in a straight line. The bar 54 has trunnions 54' which slide in slotted guideways 55, secured to the end frames 1. Operating rods 56 are secured to the ends of the beam 54 and, extending downwardly adjacent each side frame, are pivotally connected at their lower ends to arms 57 journaled upon the rod 4. The outer end of the arms 57 is connected by a foot-board 58, constituting a treadle. Helical springs 59 are provided and arranged with one end connected to the end frames as at 60, and the other end connected to the rods 56, as indicated at 61. As a result of these springs the treadle 58 and actuating beam 54 are normally held in the elevated position shown in the drawing. When it is desired to operate the cutters, the t'readle is depressed, thus drawing the actuating bar down and causing it to engage the caps 53 mounted on the main arms 11. The cutter arms are thus forced downwardly against the anvils, the springs 52 yielding so as to insure each cutter being firmly and operatively pressed against its corresponding anvil.
If, for any reason, it is desired to throw any particular cutter out of action, it is simply necessary to loosen the corresponding thumb nut 51 and swing the clip 50 around to such an extent that the cap 53 and spring 52 are withdrawn from the path of movement of the actuator bar 54. In Fig. 5, the clip is shown in dotted lines as swung to inoperative position.
A suitable work-table is supported by the frames 1 and extends along behind the series of cutters. This table preferably has a thin, forward edge 63, formed of metal or other suitable material, which lies adjacent the anvils 21. Mounted on the edge 63 is a gage, which is shown in detail in Fig. 4. This gage consists of an angle strip 64, having near its ends transverse slots 65, through which pass clamping screws, and this strip may be adjusted in accordance with a scale 66 formed on the table and clamped in such a position as willlproduce the button-holes the desired distance from the edge of the work. The vertical flange of the strip 64 is provided with an extended longitudinal slot 67, through which works a clamping screw 68. This screw 68 passes through one arm 69 of an angle bracket, the other arm 70 of which constitutes a stop against which the end of the garment abuts, so as to properly position the garment under the cutters. This gage is particularly useful in correctly locating the lapel buttonhole.
In front of the cutters is provided a shelf or platform 71, supported on brackets 72, secured to the end frames 1. These brackets are provided with "slots 73, through which work screws having thumb nuts 74.
By this means the shelf 71 can be adjusted vertically to the desired height.
It will thus be seen that we have pro vided a machine which can be quickly adjusted to accurately cut a series of buttonholes of any desired spacing at a single stroke, and it is thought that the many advantages of our invention will be readily appreciated without further discussion.
