BUTTN-HOLE-CUTTNG ATTACHMENT FOR SEWlNG-MACHINES.

EBPECEICATEON forming part of Letters Patent No. 314,046, dated March 17, 1835.

Application filed Match 13, 1F94. (Xo model.)

To all whom, it may concern.'-

Beit known that l, EDWARD B. MOORE, a citizen of the United States, residing at Vest Chester, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Button-Hole-Cutting Attachments for Sewing-Machines; and l do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification, in which- Figure 1 is a side elevation of my improved cutting device. Fig. 2 is a plan view. Fig. 3 is a bottoni or under side view. Fig. 4 is a detail view, and Fig. 5 is a perspective view, of the punch or cutter holding lever. Fig. 6 is a perspective view of a sewing-machine, showing the button-holecutting punch in its operative position in full lines and in its inoperative position in dotted lines.

This invention has rela-tion to button-holecutting attachments forsewing-machines, and has for its object the provision of cutting devices which may be conveniently adapted aud applied to a machine having the requisite ap pliances for stitching the button-hole.

In an application of even date herewith, filed by George H. Rehfuss, No. 124,105, there Vis embodied a peculiar construction and arrangement of luitton-hole-feeding mechanism, based on the general plan and principle shown in the patent of Chas. M. Banks, No. 286,989, dated October 28, 1883. Such `mechanism, among other peculiarities distinguishing it from the Banks feed, is designed and adapted for the accommodation of the cutting mechanism, and to identify and detlne the nature ofthe improvements included in said application reference is therein made to the cutting devices which constitute the subject of this application, and the same are shown and incidentally described without being claimed.

The present invention is, accordingly, for the sake of clearness and comprehension, to be considered as an expedient especially adapted for use in connection with the feeding devices embodied in said application, but not necessarily confined thereto, since the cutting mechanism constitutes a separate and distinct attachment auxiliary to, but not brought into requisition during the feeding operation.

In the Banks patent the ratchet and pinion of the feeding mechanism lie close to the four-- A designates the bed-plate of a sewiug-machine of, say, the Vheeler &Wilson standard type, cast with the longitudinal webs a a and the transverse webs b b. The web b is 11e-enforced at c to form a bearing or box for the main shaft B.

The working parts of the sewing and button-hole-feeding mechanism are omitted, as being unneceisary matter for description and illustration.

When the feeding mechanism described and shown in the Rehfuss application is used, the ratchet and pinion are located above the web b, and thus leave space between the point or lines x and y (which latter coincides with the path of the needle) for the anvil and shoes of the cutting attachment..

C designates the anvil, which consists of a block of metal faced, if necessary, with brass or copper, 'and preferably indented or diesunk in the outline of a button-hole. vSaid anvil lies above the axis of the main shaft, and normally with its face below the lower plane of the feed-plate, which therefore feeds Y above and unimpeded by said anvil. The latter is designed to be lifted into the buttonhole slot of the feed-plate and rotary disk when cutting is to be done, and is therefore an adjustable device. For the purposes of such adjustment the anvil is attached to a shoe or wedge, D, beveled on its under side,

as shown, and hinged to the bed of the ma Ico chine, and below this shoe lies another bcveled shoe, D', which moves transversely of the bed of the machine in or upon guides d d' attached to said bed.

To render the movementof the parts steady and uniform,the shoe-plate D may be slotted at d2 to embrace the depending web-extension d of the shoe D.

E represents a link connecting the shoe-plate D with a crank-arm, E, on the lower end of a turning post, E2, to which is attached the cutting-tool, operating as hereinafter described.

When the post E2 is turned to bring the cutter into position, the shoe D slides in inipingement with the shoe D, and so raising the latter and the anvil'into the cutting plane. A reverse movement allows the anvil to drop out of said plane and below the plane of the feedplate.

F designate the cutter-holder, consisting` of a lever-like casting or metallic brace comprising the box f,in which the cutting-tool works, the handleextension f, and the hinge-extensionj'E. rIhe latter is hinged to the standard or post E2, which rises,as shown, through the bed-plate, outside of the web a', and the cutter-holder may thus be lifted and lowered to adjust to its requirements. It may also be .turned around, as already suggested,with the post E2. When not in use, the cutter-holder lies at one side of the machine lengthwise thereof, a stud, G, in its outer end entering a hole, G', in said bedplate and holding it in place.

Vhen the cutter is to be used,itis lifted and swung around under the needlearm, so as to lie transversely ofthe machine and behind the needle bar'or head. In this position the stud G,which has a notch or groove at Q,ts a hole, G2, in the bed-plate, and is secured by a springcatch, 7i, to prevent prying upward when the leverage of the cutting-tool is brought into play. A knob or thumb-piece, L, rising from the latch h through aslot, lz?, in the bed-plate, is used for the disengagement ofthe latch from the stud. The end ofthe latch is beveled, so as to recede automatically and engage under pressure with the stud.

The cutter consists of a punch, H, shaped to conform to the outline of the button-hole, M

and mounted on the end of a spring-retractible lever, I, which is pivoted within a recess, I', and to the cutter-holder. Said punch is actuated by means of an eccentric-lever, K, by raising which the punch is lowered and forcibly pressed through the cloth, thus stamping or punching` outthe eye of the button-hole and cutting the slit for the length. l

By means of the eccentric I obtain extraordinary power, and am enabled to cut easily through any thickness or quality of material.

The position of the cutter-holder and the cutter and eccentric-lever are such as to meet no obstacle in the way of their movement.

Vthat I claim as my invention is as follows:

l. In a lmtton`l1ole-cutting attachment for sewingunachines, the combination,with a swiveled punch-holdcr carrying an independently movable punch, of asliding shoe connected with and operated th rough the medium of said punch-holder and a hinged shoe carrying an anvil or die upon which the punch cuts, said shoes being beveled on their contiguous faces for conjoint action, substantially as shown and described.

2. The combination, with a scwingniachinc, of a buttonhole-cutting attachment comprising the following parts: a die oranvil mounted on an arm or shoe hinged orpivoted to the bed-piece ofthe machine, a sliding shoe fitted in guides on the bed-piece and located beneath the anvil or die support, and a lever constituting the punch holder and hinged to a swiveled post having its bearing in the bedpiece at one side thereof and connected with the sliding shoe,said punch-holder being provided with a punch or cutter and an eccentric-lever for operating the sanie,substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of March, 188i.

EDWD. B. MOORE.
