SNOV MAGOUN, OF NEWTON, MASSACHUSETTS, ASSIGNORl TO MOORE 8v v CROSBY.

IMPROVED MACHINE FOR CUTTING AND BEVELING PRINTERS RULES.

Specification forming part of Letters Patent No. 9,964, dated August 2 1853.,

To all whom it may concern:

Be it known that I, SNOW MAGOUN, of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Machine for Cutting and Beveling Printers Rules; and I do hereby declare that the following description, taken in connection with the accompanying drawings hereinafter referred to, forms a full and exact specification of the same, wherein I have set forth the nature and principles of my said invention by which it may be distinguished from others of a similar class, together with such parts as I claim and desire to have secured to me by Letters Patent. v p

The iignres of the accompanying plate of drawings represent my improvements.

Figure l is a plan or top view of my machine. Fig. 2 is a transverse vertical section of the machine, taken in the plane of the line A B, Eig. l. Fig. 3 is a vertical section taken in the plane of the line C D, Fig. 1.

Printers rules-the strips of metal used by printers for ruling lines-have hitherto been cut oft' and beveledby a slow and tedious process by hand, the strip being usually cut off by a saw and the edges afterward mitered or beveled by ling. By my improved machine they can be finished with much greater speed and nicety than by hand, being cut off and beveled by a tool set in a sliding carriage and operated as will be hereinafter explained.

a a o. a in the drawings represent the bedpiece or bottom frame of the machine, to which are attached the standards b b, in which are the bearings for the sliding tool-carriagec cc.

In this carriage are placed the cutting-tools e and f, the. tool e being used for cutting the rule off square and the tool j' for beveling the rule.

. The strip of metal from which the rule is to be cutis placed upon the bed-piece a a, and rigidly held by the set-screws g g, and at the end by the slides h h, fastened in any desired position by set-screws t' t'. The tool-carriage c c c is moved forward and back across the bed-piece a a by the handle k 7c, turning on a fulcrum at Z, and jointed to the arm m, which is attached to the tool-carriage at n. The tools are depressed, as the cutting progresses, by the screws o o, and raised up again when the screws are relieved from the tools by the springs 1) p.

By the above-described arrangement it will be seen that the rule can be cut to any desired length and also beveled to any desired angle by changing the bevel of the tool accordingly, these results at the same time being effected with much greater speed and nicety than by the ordinary method of cutting printers rules.

Having thus described my improved machine for cutting printers rules, I shall state my claim as follows:

The machine hereinabove described for cut.

ting and beveling printers rules, constructed with a sliding tool-carriage, which carries the cutting-tool forward and back across the rule, as above set forth.

SNOTV MAGOUN. TVitnesses:
