JOHN H. GOODFELLOW, 0F TROY, NEW YORKhe Letters Patent No. 107,248, dated September 13,- 1870.

IMPROVED BIAS-CUTTER.

n schedule referred to in these Letters Patent and making part of the name.

.Be it known that I, JOHN H. Goonnnnnow, of Troy, in the county of Rensselaer and-State of New York, have invented a new'and useful Bias-Gutter, of whichv the following is a full,'clear, and exact description, which will enable others skilled in the art to which this invention pertains to understand, make, and use the same, reference being had to the accom panying drawing making a part of this specification, in which Figure 1 represents a perspective view of my invention.

Figure2 represents a transverse section of fig. 1,

FigureGrepresents a plan or horizontal view of another modification of my invention.

Like characters refer to corresponding parts in the various figures.

The object that I have in my inventionis the construction of an instrument for cutting various fabrics, obliquely to their warp and weft, and commonly known as bias-cutting, thus obviating the inconven-' ience, and often waste of material, attending the bias cutti'ng ot'silks', satins, velvets, and other woven fabrics, by the means now commonly employed; and which invention consists in the construction, arrangement, and combination of its various parts, as hereinafter more fully described.

From one side of the straight edge A extends the arm B, in such a manner that whenthe edge a of said straight edge is placed against the edge of the table or counter such arm B will. describe an oblique angle therewith.

. At the end of the arm-Bis a hinge, clamp, or equivalent device, 11, forming a fulcrum for the lever as to move back and .forth in the slot cl, (see figs. ,3

and 4,) and inwhich guide 0 is fastened to the blade I f, in such a manner-that its cutting-edge will be upward, audits point extend to or nearly to the bottom of the groove (1, (see fig. 3,) and to the upper side of the guide 0 is attached a ring or handle, 9.

In order to out a piece of cloth biasing with this instrument, as above described, place the edge a of the straight-edge A against the edge of the table or counter, and. lay the cloth across the arm B so that its selvage will be parallel with the side of said .table or counter, press the lever G down upon the arm B, and run the knife along the slot (I, thus cutting the cloth extending across the same between the said arm B and lever c.

Another modification of my invention may be formed by dispensing with the slot 41 in the clamping bar or lever o, and in such case it may be made somewhat narrower thanv the arm B, substantially the same as it would be if that portion of such clamping bar 0 extending along one side of said slot d were removed; and in such case the groove d in the arm B may be dispensed with, (see fig. 6,) and the fabric held between 'the clamping bar or lever c and arm B may be out by running the knife-blade withits cutting edge downward along the edge of said bar 0.

In order to hold the cloth tightly between the arm B and lover c, I provide such arm B and lover a with one or more tdngues and grooves, i, (see fig. 2,) or

their equivalent, or I make the arm B or lever c, or both, curving 'upon their surfaces of contact, substantially as shown in fig. 5.

The straight edge A may be made of any conven-' icntor desired length, and the same graduated, substantially as shown in fig. 6, for the purpose of measuring off the cloth preparatory to cutting or marking the-bias thereon.

Having described my invention,

\Vhat I claim as new, and desire to secure by Letters Patent. is

1. The combination of straight-edge A, arm B,'and clamping-bar or.lever c, constructed and-arranged substantially as'desoribe 2. The knife D,-c ons tructed substantially as specified. v

The above specification signed by me this 2d day of Jnly,1870.
