IMPROVEMENT IN BUTTON-HOLE CUT-reas.

Specification forming part of Letters Patent No. 4 l ,725, dated February 23, 1864.

(See dotted lines.) The guide eis riveted io the blunt edge ot' the blade, u. The guard d consists of an extension of guide e. This extension passes over the point of blade a., and is then bent back at an angle nearlycorrespon'ding w-ith the edge of cutter c, (see dotted lines, Fig. 1,) and having reached beyond the acute angle ofc is made to curve downward and rest on the lower edge ot' blade a.

The advantages of this arrangement will be easily seen. When the cloth is single and laid on the guide e, it is kept smooth, and, loeing supported on both sides of the slot, it cannot recede when under the action ofthe cutter c. If the material to be cut should be double 0r in plaits, as in shirt-bosorns, the upper plait, which is not designed to be cut, is made to rest on the guard d, and thus placed beyond the reach of the cutter. Ihe operator can with my machine cut button-holes of any desired length without having a screw to set the blades at a particular gage.

Having thus described my cutter, what I claim, and desire to secure by Letters Patent, 1s-

The guide e and guard d, in combination with a button-hole cutter, constructed and operated substantially as herein set forth.

To all whom t may concern:

Be it known that I, MICHAEL M. SHELLA- BERGER, of Randolph county, in the State ot' Indiana, have invented certain new and useful Improvements in Button-Hole Glitters; and I hereby declare that the following is a true and exact description ot' the saine, reference being had to the accompanyingdrawings, and to theletters of reference marked thereon. The nature of my invention consists i'n the use of certain devices for facilitating the cutting of button-holesin cloth, whethersingle or in plaits. r

Figure 1 in the annexed drawings represents a side elevation of my cutter. Fig. 2 is aplan view of the guide.

The letters a and b represent the two blades, which correspond in forni to those of a pair'of scissors. The upper blade, b, is made shorter than the lower one by about threeveighths of an inch, and is square at the end. To the in-- side of blade b the base of the triangular-cutter c is riveted. The cutterc is made to incline slightly inward when the blades a and b are closed, as seen in dotted lines Fig. l. The hypotenuse or longest side of cutter c is that it may perform its office of cutting when it passes the lower blade, a. e represents an oblong slotted plate of metal, the slot being of sufficient length to suier the cutter to pass through it when the blades a and b are closed.
