IMPROVEMENT IN` PRINTING-PRESSES.

Specification forming part of Letters Patent No. 131,950, dated October 8, 1872.

To all whom it may concern:

Be it known that we, CHARLES G. HAVENS and FEED. 0. PENEIELD, of West Meriden, in the county of N ew' Haven and vState of Connecticut, have invented a newImprovement in Printing-Presses; and werdo herenection with the accompanying drawing and the letters of y, reference marked thereon, to be a full, clear, and, exact description of the same, and which said drawing constitutes part of this specification and represents, in-

Figure lA a side view, the standard removed for illustration of the invention, and in Fig. 2 a sectional view.

This invention relates to an improvement in printing-presses, the object being the produc' tion of a small press of cheap construction- Such as are commonly known as boys7 or toy presses; and the invention consists in the combination of the bed and platen, both swin gin g` and Combined by levers with mechanism, whereby the platen drops' from the front and the bed is turned up to receive the paper and closed together for the impression in nearly a vertical position.

vA are vthe two ends of the frame-connected together by -rods a al a2 a? extendingfrom one frame to the other. On the rod a the bed B is hung so as to turn freely thereon to the position denoted in broken lines and return. On this bed thechase G is secured in any convenient manner. Beneath the bed an arm, D,

extends downward, from which a connectingrod, E, extends to an arm, F, of the lever G, the said lever G being pivoted at al, so that drawing down tlielever to the position denoted in broken lines, Fig. 2, the bed with the chase is brought into a vertical position. H is the platen arranged upon an arm, I, the said arm Iy extending to and connected with the. pivot d, which connects the arm D of the bed with the arm E. This arm I is supported by a connection, L, rocking upon the rod a3. The.

length and pivoting of these levers are proportioned, and relatively to each other, as seen in Fig. 2, so that the drawing down of the lever G, as denoted in broken lines, brings down the bed and carries up the platento meet each other in nearly a vertical position, as seen in Fig. 2; hence, the paper placed upon the platen, (or upon the type,)itl1e platen and bed with the type pressed together produce the impression required.

We claim as our invention-- The reciprocating bed B, combined with the reciprocating platen H, by means of the lever I and connection L, and operated by the lever G and link E, substantially as described, and so as tovoperate as herein set forth.
