IMPROVEMENT IN MACHINES FOR CUTTING-'AND MITERING- `.'PIRINTEIRS RULES.

Specification forming part of Letters Patent No. 111,896, dated February 21, 1871.

To all zrhom it 'may concern:

Be it known that I, FRANK H. AIKEN, of Franklin, in the county of Merrimack and State of New Hampshire, have invented a new and Improved Machine i'or Cutting and Mite'ring Printers7 Rules; and 1 do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accom panying drawing, forming part ot' this specification.

This invention relates to improvements in machines for cutting and mitering printers7 rules; and it consists in an arrangement, in connection with a portable base, of certain devices herein-alter described and specified in the claim.

Figure 1 is a perspective view ot' my improved apparatus; and Fig. 2 is a transverse section on the line .fr .r of Fig. 1.

Similar letters ot' reference lindicate correspondin g parts.

A is a. platform, preferably rectangular in form, made of metal, and ot' any suitable size,

' on which, near one corner, is a raised bed, B,

having a broad, shallow groove traversing its upper tace, parallel with the end walls of block A, in the bottom of which is a fixed cutter, U, at the iront of the inner end of which a shearcutter, D, works, said cutter being mounted on the hand-lever E, which is pivoted to an ear, F, rising up from the bed.

G is a supportingrod for a gage, H, for gaging the lengths of the plates to be cut. Said rod projects from the side of the bed in the vertical plane of the groove, holding the bed-cutter C at the end opposite the cutter, and the gage, having a lug, I, with a hole fitting the rod G, slides back and forth on it, and is held at any point by a thumb-screw, K.

The said gage has a notch at L, in which one end of the plate M to be cut rests 5 but it may be reversed on the rod H, and the other end presented toward the cutter when short pieces arc to bc cut. v

This cutting-bed andthe cutter are so arranged that the handle works over the bed in its longest way, and is, therefore, prevented from projecting away from it into or over space not occupied by it, which would be alcss compact and convenient arrangement.

N is the holder for holding the rules to be mitered. It consists of a angle-bar of metal, and is pivoted at one end at the edge() of the bar, near the central point between the ends, and the other end has a clamping-screw, P, working in the curved undercut slot Q in the bed, for holding it at any angle to which it may be adjusted.

It is a miteriug-tool, consisting of a tile or other similariustrument, arranged on a holder, S, which is suspended from the guide-rail T, so a-s to be moved back and forth against the end ofthe rule when held in the holder N.

This tool-l'xolder S has a handle, U,for working it, and one or more metallic screws, V, whicl bear against the edge of the bed, to regulate or guide the tool.

The guide-rail is mounted in supports W, projecting from the bed.

Having thus 'described myinvention, I claim as new and desire to secure by Letters Pattent- 1. The tool-holder S, sliding on rod T; the cutter 1t, and set-screws V, combined with the bed A and adjustable holder N, substantially as specified.

2. A printers rule-cuttin g and miterin g apparatus, consisting of the cutters D C, the gage therefor, the adjustable holder, and reciprocating tool, and tool-holder, all arranged on one bed or platform, substantially in the manner specified.
