BUTTONHOLE-PUNCHING- MACHINE.

Application filed July 3, 1912.

T 0 all whom it may concern:

Be it known that I, MANnnL-BRowN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Iman improved machine wherein the portion of the garment in which a button hole is to be cut, is held stationary, while a counterplate presses said portion against a cutter of suitable configuration to cut a button hole shaped slot in the garment.

Another object of the invention is to provide a support for the counter-plate, adapted to hold plates of varying operative length, so that button holes of different size may be out without exchanging the cutter.

Another object of the invention is to provide means for actuating the machine by foot power in contradistinction from hand cutters which are frequently used in the art, and which are extremely diflicult to operate, particularly when button holes have to be cut in heavier fabrics, like cloth for mens garments, overcoats or such like.

Vith these and other objects in view, the invention is described in the following specification and illustrated in the drawings and defined in the appended claims In the drawing: Figure 1 is a longitudinal section through a button hole cutting machine, partly in elevation; Fig. 2 is on a larger scale a horizontal section through the cutter and the means for securing the same in the machine; Fig. 3 is an elevation of the part shown in Fig. 2; Fig. 1 is a perspective view of the cutter blade. Fig. 5 is a top plan view of a counter-plate and its support; Fig. 6 is a section through the same, showing the removing pin in elevation.

Fig. 7 is an elevation, partly in section, of modification of a support for the multiple counter-plate.

Fig. 8 is a top plan view thereof.

The upright 1 is a casting, preferably of a circular cross section, cored out so as to provide a hollow inner space 2, and terminating in a bent head portion 3, at the top, and in a broad base plate 4, at the other end, in which holes, 5, for the reception of bolts Specification of Letters Patent.

(not shown) are provided, whereby the machine may be secured to the floor of the workroom. At the depending end of the head portion 3, a cutter 6, is fastened by means of clamping plate 7, which is detachably secured to the head portion by screws 8 extending through the holes 9, in the cutter blade and'threaded into the head portion 3. A gage 10 is adjustably connected with the stationary cutter; thegage comprising a frame portion 11 and an angular projection 12. A clampin screw 13 extends through the frame into the plate 7.

The cutter comprises a straight portion 13, provided with holes 9 for the passage of screws 8, and a circular, preferably tapering portion 14, adapted to cut the enlarged portion of a button hole, as will be wellunderstood by persons skilled in the art. The circular and straight portions are sharpened at their lower end to provide a cutting edge 15. The clamping plate 8 has a suitable recess 16, in'which the tapering portion 1 1 is secured when the parts are clamped together.

A counter-plate support 17 is pivotally secured at 18 to the upright, and terminates in a seat 19 for the counter-plate 20. The latter is preferably circular to conform with the circular recess ofseat 19, so that the counter-plate may be inserted into its seat and centered with respect thereto by rotating the plate until it is in proper position. It is then locked against rotation in this position by a pin 21, projecting from the seat into a recess 22 of theplate. The latter comprises a raised portion 23 and a lower oifset portion 24. When the counter-plate support is advanced toward the cutter, the raised portion only comes into operative engagement with the cutter6. The latter will then punch a slot corresponding to the length of the line of contact of the raised portion of the counter-plate with the edge, while the offset por tion remains out of contact.

A pin, 27, is slidably'disposed in an aper-' ture, 28, of the counter-plate support and is provided with a head, 29, which holds the pin from dropping out of the aperture.

l/Vhen it is desired to remove a counter-plate from its seat, the pin 27, is pushed upwardly, engaging thereby the lower face of the inserted counter-plate and forcing the same out of the seat.

When it is desired to cut button hole slots of a different length, other counterplates may be inserted which have the raised 36, alternating with recesses 37. The raised portions 36 have different lengths, so that by rotating the counter-plate 30, on this support, a raised portion of suitable length may be brought into opposition with the cutter blade 6, and uponactuating the support the respectiveraised portion will be brought into operative position with respect to the blade. For the purpose of locking the multiple counter-plate 30, in adjusted position, a spring-controlled pin 50, is provided, which extends through a tine 32 of the support 31, and projects into one of the apertures 39, provided in the plate 30. These apertures 39 are disposed at equal distances from the center of the pin and in suitable posit-ion with respect to each of the raised portions 36, so that the plate is locked when a raised portion is opposed to and parallel with the edge of the cutter blade. By withdrawing the spring-controlled pin 50 from the respective aperture 39, of the plate, a further rotation of the plate may be effected. An extension 40, on- I the support 17 projects into the hollow space 2, of the upright, and is connected by means of the link 41, with a lever 42, pivoted at 43, to the upright 1, and provided with a treadle portion 14, at its projecting end. For the purpose of automatically restoring the lever 42 to initial position when the pressure thereon is eased, a spring 15, is connected with the lever, the other end of the spring being connected to a hook A6, which is threaded into the metal of the up right. r

The operation of the device is as follows: A counter-plate having a suitable operative length, is brought into opposition with respect to the cutter blade, 6. The gage 10 on the blade 6, is adjusted in accordance with the distance which the button holes shall places where button holes are to be provided in the garment are usually marked with chalk lines or in some other suitable manner on the fabric. The operator holds the fabric with the marked portion against the stationary cutter, 6, and depresses the treadle tet with his foot, whereby the

support

17 or 31, and the counter-plate thereon,

is oscillated toward the edge, which in this manner produces a slot in the garment, having an enlarged end. Upon the release of the treadle 14, the counter-plate is withdrawn from engagement with thegarment and the latter may be shifted so as to bring another marked line in engagement with the cutting edge 15.

I claim:

1. A button hole cutting machine comprising a standard having a depending cutter support, a cutter removably secured thereto and projecting downward, a counter plate support below the cutter support hav ing a circular recessed seat in its upper face, provided with a central opening extending through the support and an eccentrically located, upwardly projecting pin, a movable pin in the central opening, and a counter plate rotatably adjustable in said recessed seat, said counter plate having a portion of its upper surface cut away to shorten the operative surface opposed to the cutter.

2. A button hole cutting machine comprising a hollow standard having a hollow bent head portion, a cutter rigidly secured 9p to said head portion and having the cut ting edge directed downwardly, a gage ad-v justably secured to the head, means for holding said gage parallel to the cutting 2 edge, a counter-plate support pivotally mounted on the standard and projecting intojthe interior thereof, another'portion of said counter-plate support projecting into opposition to said cutter, a rotatably adjustable counter-plate carried by said support, said counter-plate having surface portions at different distances from the cutting edge, a treadle pivotally mounted in said standard and projecting into opposite direction with respect to said counter-plate support, and a link connecting said treadle inside the standard with said support.
