JAMES LEWIS, OF PRATIV ILLE, NEVKYORK.

:PRINTING-PRESS.

Specification of Letters Patent No. 12,185, dated January 2, 1855.

To all whom t may concern.'

Be it known that I, JAMES LEWIS, of Prattville, in the county of Greene and State or' New York, have invented a new and Improved Printing-Press; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a side elevation of my 1mproved printing press. Fig. 2 is a longitud inal vertical section of do. Fig. 3 is a detached p-lan or top view of the bed, ways, and ease bar of the fly.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to a new and improved printing press and consists 1st in the employment or use of a fly constructed arranged and operating as will be hereafter shown, and 2nd in the combination of the fly, with the cylinder and bed plate of the press.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

A represents the frame of the press, having two uprights (a) (a) one at each side in which the axes (b) of a cylinder B has its bearings. At each end of the cylinder' B there are cogs or teeth (c) which extend half way around the cylinder see Figs. 1 and 2.

C is t-he bed of the press on which bed the form from which the impressions are taken is placed. The bed C runs or works upon ways (CZ) (el) which are placed longiw tudinally on the upper part of the frame A. The ways are shown more particularly in Fig. 3. Ateach side of the bed C there is a rack (e) both racks are shown in Fig. 3 and one in Figs. l and 2.

D, Figs. 1 and 2 represents the fly which is'formed of two uprights (f) (f) attached by pivots to the ends of a bar E which works or runs on the ways (cl) (cl). The base bar detached from the uprights is shown in Fig. 3. The upper ends of the uprights are connected by a horizontal bar or cross piece F having lips (la) on its front end, see Figs. 1 and 2. Directly underneath this bar or cross piece F there is a bar G which is secured by pivots at its ends to t-he upright (f) (f). At each end of the bar G there is a small arm to which a spring (7c) is attached. The springs (la) lips on the bar or cross piece F. At the back of the bar G, at about its center,.there is a rodl (Z) which projects outward a suitable distance as shown in Figs. 1 and 2.

The bar E to which t-he uprights are attached has horizontal bars (m) secured one at each end, or near the ends, said bars restonledgesor strips (n) by the side of the ways (ci) (el) as clearly shown in Fig. 8. The ends of the bars (m) have projections or hooks (o) (0) upon keep the edge of the bar G close against the them as shown in Figs. 1 and-2`and by doty y ted linesin Fig. 3. And the inner end of the bed C is provided with buttons (ya).

To one side of the uprights (a) (a) there are attached arms (g) (gl) one to each, andy at the upper ends of those arms are secured bent levers (r) (r) provided with springs (t). At each end of the cylinder B there is a pin (u) the position of which is shown by dotted lines in Fig. 1. And there isv attached to one of the uprights (a.) a bent rod (o.) shown in Fig'. 1.

Across the face of the cylinder B there is a rod H having fingers (w) attached to it, see Fig. 2, one end fof this rod is provided f with a spring (not shown) which keeps the lingers down uponl the cylinder. The op'-- posite end of the rod is bent over at right angles as shown by the dotted lines (y) in Fig. 1. i

I is a horizontal fly board attached to the back end of the frame A as shown in Figs. 1 and 2. I

J, J, J, are the ink. rollers arranged as usual and driven in any proper manner.

Operation: The form shown in red in Fig. 2 and indicated by (b) is placed upon the bed C. And the paper to be printed .is f

placed upon a feed board indicated by (a) see dotted lines in Fig. 2. The cylinder B is then rotated and when the bent end (y) of the rod H comes in contact with the bent rod (o) attached to the upright (a), the fingers on the rod H are raised upward from the cylinder B and the edge of the sheet of paper is slipped underneath them, the fingers falling upon-the edge of the sheet when the bent end of the rod H has passed the bent rod (o), the sheet being thus attached to the cylinder B is carried around with it, and is pressed between the cylinder and the form shown in red and designated by `(6') Fig. 2, the form being uponv the bed C, which is moved in the direction of arro7 1 during the time the impression is given by the teeth or cogs (c) on the ends of the cylinder gearing into the racks (e) (e). When the fingers (w) get nearly to the point at which they receive the sheet, the pins (u) at the ends of the cylinder B acts upon the bent levers (r) and the bar G is depressed, that is, its inner edge, and the edge of the printed sheet is caught between the bar Gr and lips (it) of the bar F as shown in Fig. 2 the sheet being shown in red and indicated by (c) the buttons (79) (p) 110W come in contact With the bar E of the fly D and force it back till the lower ends of the uprights (f) strike against pins (cl) at the sides of the frame A, see Fig. 2 and the top part of the uprights (f) (f) are thrown back the rod (t) passing over a bar (e) on the iiy board which causes the inner end of the bar G to be depressed and the printed sheet falls upon the {iy board I. At this time the cogs on teeth (c) on the cylinder B have just passed the racks (e) (e) on the bed C and the bed G and the fly D are brought back to their original positionA by a Weight K Which is attached to the bed by a cord A The above press is extremely simple and Will Work with great rapidity and with a small expenditure of power. They can be made at a small cost and are not liable to get out of repair.

Having thus described my inventiomwhat l claim as new and desire to secure by Letters Patent, is,

l. The employment or use of the fly D constructed arranged and operating in the manner and for the purpose as herein set forth.

2. I claim the combination of the ily D, cylinder B and bed C, When the above parts are arranged operated as herein shown and described.

JAMES LEWIS.
