IMPROVED MACHINE PORGUTTING CARDS.

die Stilisti: refont is in this: Eaters tant mit mating sul nt the, same TO ALL WHOM IT MAY CONCERN:

113e it known that I, E. J. HUNT, of Concord, lin the county of Merrimack, and State of New Hampshire have invented a new and improved Machine for Cutting Cards; andI do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled inthe art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a vertical longitudinal section of my improved'card-cuttingmachine.

Figure 2 is a bottom view ofthe cutter', detached.

Figure 3 is a transverse section taken in the line a: im, iig. 2.

Similar letters of reference indicate like parts.

The nature of this invention consists in attaching anV adjustable cutter for cutting carte devz'stea, and cards of all kinds, -sizes, and shapes, upon the end of a spring-arm, which liftsthe cutter from the cutting-board or sirface after the card is cut, which cutting-board is setin a recess, in an under frame or base, and is attached to a cog-wheel, which engages in another wheel, to receive intermittent rotary motion therefrom by means of a ratchet-wheel, operated by a pawl connected with the rock-bar, upon which the `spring-cutter arm works for the purpose of presenting a new faceto the cutting-knives every time the cutter descends, as hereinafter more particularly described.

A representsa base-board or box\`rame, in which isset the circular cuttingboard, B, made of copperface or other soft metal in the usual manner, which is attached to or set upon a cog-wheel,' C, the axis of which is stepped in the base, A, and which is geared in to the wheel, D, that carries on its upper side a ratchet-wheel, m, which is moved, one or more teeth at a time, by the pawln connected with the rock-shaft a, hung at one'end of the base-board, A, to carry the arm E with the cutter-box F. Under the'cuttenarm E is fastened'a springt, which lifts the arm when a card has been cut. When the arm is depressed to cut'a card on the board B, the card is held under the frame c by means o'f aV spring, d. The motion of the rock-shaft a downward draws the pawl n back, and when the arm is raised by thespring d,"thei pawl n 'engages inthe teeth of the ratchet-wheel m, and turns the cutter-'hoard B slightly, to change its position under the cutting-knives. The cutter-bou F is divided into four adjustable sections, e e, which carry the knives p p, and are fastenedto the cap-plate u by screws, h h, through slots in the cap-plate. The sections e e are grooved on the under side transversely, from a common centre, to slide in and out, as required, upon ribs or tongues, s s, on the` capfplate'mtoset the knives on the four sides ot' the box F nearer' togethery or wider'apart for cutting cards of dilferent sizes. `This contracting and expanding movement ofthe `sections e` e with the knives is effected byfmeans Vof -a pin, r, in the lower side oi each section, which works in eccentric curved slots, u, made in a circular plate, H, set upon a screw, k in the centre of the cutter-box. 'B tui-nin the late H in one directionthe sections e e, with the a y g ,P

knives, are contracted, and by turning it in -tho opposite direction vthe sections and knives are expanded, by the pins r moving in the eccentric slots u, as will be readily understood.

The cutter-box may be arranged for cutting oval or other shaped cards, upon the same principle of coustruction. y

Having described nay-invention, I'claim as new, anddesire 4to secure by Letters Patent- 1. The rotary cutter-bard B, in combination with the gear-wheels C D, the ratchet-wheel m, andthe cuttcrarm E, constructed and operating substantially as and for the purpose herein described.

u 2. The adjustable sections e e, with the knivesp p, and the circular slotted plate H, in thc cutter-box F,

constructed'and operating substantially as and for the purpose specified.
