l; aras rn GEO. P. GORDON, OF NEW YORK, N. Y.

PRINTING-PRESS.

To all whom t may concern.'

Be it known that I, GEORGE P. GORDON, of the city of New York, in the county and State of New York, have invented certain new and useful Improvements in the Construct-ion and Operation of Printing- Presses; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specilication, and the letters of reference thereon, like letters always denoting the same part or piece in all the figures of the drawings, in which- Figure 1, is a perspective view; in this view are shown the pinion (A), and driving-wheel (B) the pinion being placed upon the driving-wheel shaft (D), in vdrawings; (on the opposite side of the press, upon the same shaft), while the spur-wheel is fast with the main shaft (C) and upon this same shaft are the following cams;'- (E) which is to raise the feed-board and also lower it at the proper times; is the cam which works the compound togglejoint to give the impression; (G) is the'cam on the main shafty by which the lingers, nippers, or grippers are caused to perform their various manipulations, being always governed in all their motions by the said cam. The feed-board (a) has upon it the pile of blank paper, the sheet being represented by the red line upon the board (see b, Fig. 1) the grippers which are to impinge against or upon the paper which is laid upon some suitable place or substance, so that the grippers may take the sheet of paper from any place from which it may be fed, to go to the impression, and thence to the place where it is to be piled in an even heap; that is, one sheet precisely on the top of the sheet that preceded it, (see (c), Figs. 1, 2, and 3,) is in red and shows the heap of paper when piled, while (d), Fig. 8, is a sheet about to be dropped from the grippers, and is about to meet the elevated or projecting fingers or sheet-stops (e, 6,) in the several figures of the drawings. f

A lever (f), is made fast to the under side of the feed-board. The opposite end of this lever rests upon the cam (E), and this cam causes the feed-board to -vibrate up and down at the suitable times to give the sheet to the grippers, and .then to raise sufficient that the platen (g), with its grippers (L) may pass beneath it. A single piece is constructed which has apparently two parts, either of which is to perform its duty of alternately inking the form and distributing the ink; these two parts occupy angular positions one toward the other; being the form bed, `and the distributing table for the ink; when in motion these travel togetherand have a revolving, alternating, reciprocating motion, which presents one of these surfaces; that is, the type surface or the ink-distributing surface constantly to the fixed, revolving, ink-supplying rollers; the ink being distributed at (lo) and imparted to the form at This bed and distributing-table act upon their axis The bed and distributing-table receive their motion from the main shaft; a connecting-rod being fast to the spur-wheel somewhat cranked or set eccentric to the main shaft; this will be known as (m, Fig. 1) a vibrating cam (n) is fast with the aXis (Z) this cam is further controlled in its movements by the vibrating arm or crank A compound toggle, of known construction is fiXed upon the main shaft, the opposite eXtreme part being fixed to the platen, on its back-side, which at the proper time, through the cam is caused to vadvance to the bed and form, and give the impression. Upon the bed and platen are guides (p), the one being male and the other female, and these serve to guide, and in some measure control the movements of these parts, so as to avoid slurs or other inaccuracies in relation to a correct impression.

Grippers (71,) are arranged at or near the front edge of the revolving platen; these nippers impinge upon the edge or margin of the sheet of paper holding it firmly within the grippers; although the grippers as here shown have a rock-shaft (g) operated so as to allow the gippers to open and close at the proper times; these movements being controlled by levers or connecting-rods which are controlled by the revolving cam A pile-board (1") is placed in a suitable place or position to receive the sheet after it is printed and upon which board the sheets of paper may be piled; upon one of the ends or sides, at or near the edge, to suit convenience, are placed certain elevated or projecting fingers or stationary stops, so arranged that as the grippers or nippers approach and open they shall pass between the fingers, these lingers meet the edge of the sheet to be piled, and relieving it from the revolving grippers, cause it to fall or drop in its place against the guides or stationary fingers (Whether one or more be used,) so that each and every sheet Will be deposited in the same place; that is, one sheet directly upon its predecessor, in an even and regular pile (as seen at c, red lines in Figs. 1, 2, and 3), resting upon the pile-board and against the fingers (e) or their equivalent, so that by this pile-board and its attachments, (the fixed fingers), the sheets Will fall, as relieved from the grippers, in an even pile, by means of the form or posit-ion of the pileboard and the projecting fingers. The red lines in Figs. l, 2, and 3 represent the piled sheets of paper as a heap, with the exception that in Fig. 3 (d) represents a.. sheet as being ready to drop into its place against the fingers and upon the pile-board; the grippers opening at a proper time to give the sheet to the fixed fingers for that purpose. The front or feeding edge of the feed-board is provided with suitable openings so that when the sheet is fed to its gage the revolving nippers will cl-ose Within such o enings and thus seize and hold the sheet of paper and carry it to the place of impression and thence to the place of deposit, Where it is arrested, as the fingers relieve it, thus causing it to be deposited in an even pile against the fingers and upon the pile-board.

I Wish it to be distinctly understood that it is immaterial hovv or When the revolving grippers shall receive the sheets of paper, as a material object is to take the sheets of paper after they have received the impression to a suitable place of deposit and there by and With the aid of the fingers or stops or their equivalent pile them in a regular heap.

Operation: Motion being given to the driving-shaft (D), the pinion imparts it to the spurWheel (B) and this to the other parts of the machine. We Will novv suppose the sheet of paper about to be or taken by the grippers; the form of the cam (F) by means of a lever connects With the platen and controls all the motions of the platen, from receiving the sheet to its place of deposit. By this I Wish it to be understood that the sheet is seized by the grippers and by them held until the sheet has been printed, peeled off the form, and carried to the place of deposit on the pile-board against the fingers (E) The impression and inking apparatus are substantially Well known, but are here produced in dierent relations, (each to the other), than has been before used. The shaft (Z) is the axis of the bed and distributing-table; the cam (n) giving to it a vibrating or rocking motion. The inking-rollers are in a fixed except that they are free to revolve on their axes. The part (2') is the bed or part of the machine Where the type to be printedA from are placed; the part (lc) is the inlr-distributingtable; these are in one piece, and as they rock to and fro, alternately, each presents itself at the proper time vfor distributing the ink and alternately presenting the form at the time the platen advances to receive the impression. The impression being given, the laten recedes, the sheet of' paper is peeled og the form, and is then conveyed to the place of deposit, on the pile-board against the stationary fingers or stops for detaining and piling the sheets of paper.

Having fully described my printing press, what I claim as my invention and desire to secure by Letters Patent is,

l. The combination of one or more sets of revolving grippers with the finger-stops, or their equivalents, for the purpose of piling the sheets of paper in an even and regular heap or pile, substantially as described.

2. I claim the combination of a vibrating feed-board with the rotating or revolving platen for the purpose of feeding the sheets of paper regularly and With precision at each rotation of the platen.

3. I claim the combination of a rotating reciprocating bed With a revolving platen, all of Which is fully described.
