JOSEPH JOHNSON, OE MARSHALLTOWN, IOWA.

Letters Patent No. 106,829, dated Ang/ust 30, 1870.

Th Schedule referred to in these Letters Patent and making part of the sama 'lo all whom 'ITL may concern.-

Be it known that I, JOSEPH Jonsson', of Marshalltown, in the county of Marshall and State of' Iowa, have invented a new and useful Improvement in Wire-Cutter; and I do hereby declare that the f`o llowing is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference heilig had to the accompanying drawing forming part of this specification.

The object ot this invention is to provide simple` and eicient means for cutting up wire into. pieces of uniform length, and at the same time pnovide a rule by means ot' which the wire is measured to any desired length, and the gauge set thereby; and

The invention consists in a sei'nicircular plate, with a graduated border, and with a grooved flange on its circular edge, with an adjustable gauge ou the flange and a spring chisel and stationary chisel on 'the plate, arranged as hereinafter more fully described.

In the accompanying drawing- .Figure 1 is a top or plan view.

Figurei? is a vertical section of fig. l, ou the line .r

Figure 3 is a vert-ical section of.' fig. 2, on the line y y, showing the cutting device.

Similar letters of' reference indicate correslwnding parts.

A is the plate, which may bc iliade of either wood or metal.

Itis semicircular in forni, with a projectingr cud, B, f'or fastening the chisel, but the chisel or cutting device may be attached\or arranged in any other snitahle manner.

C is alia-nge around the circular edge of' the plate.

On the inner sidol of the flange there -is a projecting rib, d, (seen iu fig. 2,) and also at (l, where the flange is broken away.

lhis forms a groove, li, at the angle formed by the flange andthe edge of' the plate, which confines the wire as it is forced into the cutter.

`E is the adjustable gauge, which is fast-cned to the flange by a thumb-screw, as seen in the drawing.

11 is a circular piece of' metal, marked oli" to indicate inches and. fractions of' inches on the face of the plate next the flange. v

G is the spring chisel, which has a shank, 71, and is supported by the stand I.

J is a spiral spring, which rests on the stand, and bears upwardhagainst a pin in the shank of` the chisel with a constant pressure.

K is a stationary chisel, over the edge of' which the wire to be cnt is moved. l

L, (seen'in dotted lines in fig. 1,) indicates the wire to be cut.

The gauge E is set on the flange C by the rule F,

' so as to stop the end ofthe wire at any desired point,

as thelatter is crowded over the stationary cutter K. and-between the cutting edges of' both chisels. The spring chisel G s'hcld up by the'spring J.

The wire will follow the curve of the flange, and will be confined by the rib d.

The gauge being set to stop the wire at the proper point, a blow on the spring chisel-shank will sever the- 'wire instantly.

The wire being taken from the coil, will naturally follow the groove in the flange so that the pieces of' wire cut will exactly correspond in length.

This is a cheap, simple, and most valuable article for tiuners and others who find it necessary to cut' up wire to exact lengths, for any purpose..

Having thus described my invention,

I claim as new and desire to secure by Letters Patentlhe plate A, with the measuring-rule F, the flange O, with the'rib d, by means of' which a groove is formed at'the angle, the gauge E, and the cuttingchiselsA Gr and K, the whole arranged and operating sul'istantially as and for the purposes described. 4

JOSEPH JOHNSON.
