Letters Patent No. 98,349, dated `December 28, 1869.

a A l IMPROVEMENT IIN BUTTON-HOLE .OUTTERS The Schedule referred to in these Letters Patent and making part ox the same.

. I, DANEL G. CHASE, of Boston, in the county of Suffolk, and State of Massachusetts, have invented certain Improvements in Button-Hole Cutters, of which the following is a specification.

Natwre and Objects of the Invention.

My invention consists in combining a pair of ord nary shear-han dles with a swivel-cutter and cutter-bed of peculiar construction, the cutter-bed being made ap' proximately cylindrical in form, and capable of being turned on its axis, so as to bring any desired part of its surface beneath the cutter.

The object of the invention is t-o combine a swivelcutter with aAcutter-bed of convenient form, in such a manner that the swivel-cutter may be used with equal facility for large or small button-holes.

Genera-l Descriptton.

'the cutter C, and in such a manner, that it' a piece of e-l'oth or other` suitable fabric be interposed between cutter and barrel, andthe handles be pressed together, the cutter will he forced through the cloth,..and will bed itself upon the barrel.

For convenience of cutting holes of different lengths, the barrel B has portions of its surface out away at the ends b b, so as to form facets or lieds of different lengths in the central portion, and so that by turning the barrel B on its axis, the cutter C may be brought to bear on any desired facet.

Each of the facets just mentioned, is bounded at its ends by edgeswhich are parallel to each other, and perpendicular to the cutting-edge of the knife. The surface of the barrel B is thus divided into` a definite number of facets, having parallel ends, in preference to forming the same intoa single continuous bed of triangular or trapc'oidal, form, in order that buttonholes of uniform length may be cut at different times, without the necessity of adjusting the bed always in precisely the same position.

By the present arrangement, the operator may first select the desired facet, and then choose afresh place on said facet, upon which to. cut, thus avoiding the necessity of gashing the bed so deeply, by repeated cuts in the same place, that the knife cannot work perfectly,

The arrangement also aids` the eye in selecting the tal length of the cutter C, and fitted loosely therein,

so that the cutter may rotate slightly on the pivot, such rotation being limited by the pin D, fixed in the jaw H', and playing in the slot E formed in the end of the cutter C. v

The cutter C is so placed that the middle of its Aedge will always fall on the equatorial line of the bar` rel B, and the middle of each facet being also in the same line, any downward pressure of the pivot J, on the cutter C, must cause the cutter to bed squarely on the barrel.

A gauge, G, adjustable by the s'crew g, is attached to the upper jaw for convenience of cutting the butv ton-holes at any desired distance from the edge of the fabric.

For facility of construction, the different facets of the barrel B are preferably formed into one continuous cylindrical surface. ,j In consideration of Letters Patent, grantediHalsey D. Walcott, May 17, 1853, and o'f certain inoperative claims made by T. W. G. Cook aud'Edwin R. Walker, j 4

and lcd, respectively, February 25, 1867, and Mardi 20, 1867 I do not claim t-he rotary bed B, either singly or in combination, and I do not claim the swivel-cutter C, either` singly or in combination; but What I claimv as my invention, and desire to secure by LettersIatent, is

The button-hole cutter, consisting of the jaw A, withuthe barrel B and spring s' for holding the barrel in positiomand the jaw H', with the cutter C and gauge G, constructed as described, and all "combined and arranged relatively to each other as set forth.-
