Letters Patent No. 90,518, dated Mag/25, 1869.

IMPROVEMENT IN PRINTERS SHEARS;

The Schedule referred to in these Letters Patent and making part ofthe same.

To all whom 'it may conce/m Beit known that I, CHARLES E. Fisk, of the city and county of New York, and State of New York, have invented a new and improved Mode of Cutting Printers Plain Brass Rule; and I do hereby declare that the following is a snciently full, clear, and exact descriptionl thereof, to enable one skilled in the art to which my said invention appertains, to make and use it, reference being had to the accompanying drawings,

which form part of this specification. Printers plain brass rule, out by Acommon printers shears, when put up in rule-work, leaves a space between the end of the rule and bevelled 'edge of the cross-rule.

To avoid this space or break between the end of the rule and the bevelled edge, printers, in iine Work, sometimes fileV down the end of the rule, so asy to leave a mitred point,'which fills out this space.

The nature of my invention consists in a mitre and -a holder attached to common printers! shears or rulecutter, by which the rule is held in place and the end cut oi` at one motion, leaving the mitred point complete. The mitre, being bevelled corresponding to the bevelled edge ofthe rule, does not curl the face ofthe rule in cutting.

Figure 1 represents the shears.

Letter a. representsl the mitre.

Letter a represents the cavity which the mitre enters to out, the mitre-point.

Lettere is a projection to strengthen the cavity.

Letter b represents the gauge or holder by which the rule is held in place while cutting.

Figure 2 represents a vertical section of the shears, showing the mitre marked a, the cavity which the mi tre `enters marked a', and c the projection.

Figures 3, 4,*and 5, represent the different projec tions of the mitre marked a, viz, the side, front, and top. p

Figure 6 represents a plain rule out with a mitrepoint.

This improvement can also be applied to printers common rule-cutter, the principle and movementoi` the cutter being similar to the shears.

I claim, in combination with printers shears or rulecutter of otherwise ordinary construction, the mitrecutterv a, with corresponding indentation a' and the gauge or holder b, substantially as described and forY the purposes specified.
