IMPROVED PRINTING-PRESS.

Specifica-tion. forming part of Letters Patent No. 11,064, dated June 13, 1854; Reissue No. 6211, dated November 16, 1858.

To all whom l may concern,.-

- l Beit known that I, GEORGE P. GORDON, of

the city, county, and State of New York, have invented certain new and useful Improvements in Printing-Presses; and I do hereby declare that the following is a full., clear, and 4exact description of the construction and operation of the same, reference Aheilig had to the annexed drawings, making a part of this speeilication, in which- Figure' 1 is a side view of my improved press. Fig. 2 is also a side view of the same, the side shown being opposite to that shown in Fig. l. Fig. 3 is a vertical longitudinal section of the same, the plane of section being through the center, or nearly at that point. Fig. 4 is a detached back view of the tly or carrier of the sheet of paper.

Similar letters` of reference indicate correspondin g parts in the several figures.

Y 4This invention relates to certain new and useful improvements in printing-presses 5 and it consists, iirst, in the employment or use of a shectconveyer or tly having a rotary reciprocating motion, and arranged, as will be hereinafter shown, or in some equivalent way, for the purpose of relieving` the sheet from the type when printed or removing the printed sheets and pilingthem upon a proper place of deposit; second, in giving with one inkingcylinder two distributions to the hiking-rollers for each impression, one prior to the passing of the form and one prior to the repassing of the form 5 third, in the combination oi' a spiral spring, connecting-rod, and crank-motion for operating the bed or carriage, as will be hereinafter shown. Y

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

A, Figs. l and 3, represents the frame of the press,-the upper part which is inclined, and B is a swinging or vibrating frame, attached to the frame A by pivots a, a pivot passing through each side piece of the frame. The vibrating frame B is directly over the upper and inclined portion of the frame A, and a spring, p, is attached to the frames B and A. (See Fig. 2 and 3.) Tithin the vibrating frame B there is a bed or carriage, G, which works in grooves bin the inner sides of the side pieces of the vibrating frame B. One

toin ends of the bed or carriage O' are rounded, as shown in Figs. 1, 2, and 3.

D is a toothed wheel, which is hung in the frame A, the axle of the toothed wheel having its bearing in one of the side pieces of the frame.

.E is a pinion, which gears into the toothed wheel D. The pinion E is hung upon a shaft, F, which passes transversely through the fran-1e A, and has at one end a iiy-wheel, G.

H is a connecting-rod', one end of which is attached by a joint or pivot, c, to the lower end ofthe bed or carriage G, and the opposite end passes through an eye, d, attached to the side of the toothed Wheel D, near its periphphery. A nut, e, is upon the lower end of tLe rod. Around the connectingrod H there is a spiral spring, f, the upper end of which beai s against the shoulder ofthe joint c, and the lower end against the eye d.

I is a curved arm attached to the vibrating frame B. The lower end of the arms I is about on a line with the periphery of the toot-hed wheel D, directly over its center.

J, Figs. l and 3, is a toggle attached by a pivot, g, to one side of the toothed wheel D.

K, Figs. 1, 2, and 3, is a frame containing two inking-rollers, h h. The frame Khas a shaft, t', passing transversely through it, the ends of said shaft z Working loosely in the side pieces of the frame A. At the lower ends ofthe side pieces ofthe frame K are rollers j j, one roller to each side piece. In the frame A, and directly below the inlringroll ers kh', is placed the inkingcylinder L, against y which the inking-rollers h h bear when not operated upon by the movement of the bed or carriage C, as will be presently shown.

M is a iy attached to the upper part of the frame A, (See Figs. l, 2, and. 3.) The iy is in the form of a segment of a cylinder, and extends across the whole breadth of the frame.

On one end of the ly is a pinion, N, which gears into a segmentrack, O, at the upper end of a lever, P, which hasits bearing or i'ulcrum on the shaft F of the pinion E and iiywheel G. The lower end of the lever l) lits in a grooved cam, Q, which is hung on the axle of the toothed wheel D, (See Fig. 2.) The fly M is provided with nippers 7c, which are attached to a rod l, opera-ted by a spring, m, and pin n, (see Fig. l.)

R is a ilyboard placed underneath the ily/m..

Operation: The paper is placed upon the platen at the upper' part of the frame A at Z, (see Fig. 1,) the red lines denoting the sheet of paper, and motion is given to the shaft F in any proper manner, and the connecting-rod H moves the bed or carriage C, which holds the form upward and over the paper. When at this point the toggle J acts againstthe lower end of the arm I and forces the upper end of Jthe frame B towards the platen Z and the form is pressed upon the paper, the bed or `carriage containing the form remaining stationary during the time the impression is given, in consequence of the eye e acting'against the spiral spring f upon the connecting-rod H and the upper part of the bed or carriage bearing against the stops s s. .The nippers Ylc take and hold the sheet at the point of impression and while the sheet iis resting upon the platen, and relieve it from the type after it is printed, and the nippers or ily by the operation of the cain Q, pinion N, and rack 0, then revolves a part of a revolution backward and carries the sheet around with it and deposits it upon the ily-board R, (See Fig. 3.) 'As the bed-carriage G passes downward, the sides of the bed bear upon the rollers j ofthe traine K, and the hiking-roll ers hh arein con sequence lifted 'from the inking-roller land bear against the form, and when the form has `passed below the hiking-rollers said rollers, -by their own gravity, fall upon the inkin gcyl .inder L, and are again raised from it and pressed against the form upon the upward movement of the bed or carriage. Thus two distributions are given to the inking-rollers i'or every impression, and the form inked twice, one inking on the downward movement and one on the upward movement of the bed or carriage. The return movement is given the ,'tly M on the upward movement of the bed or carriage.

It is peculiar to this machine that nippers or gri ppers are caused to advance and receive the sheet of paper, and after it is, printed place each sheet in a regular pile, in such manner as has heretofore been done by hand, and whether this be done by a segment of a cylinder or other convenient arms, or means equivaient, to convey the grippers after they have received the sheet and the impression has been given to the ily-board, I consider immaterial, as many substitutes would be readily contrived by a skillful mechanician. Therefore, whether I use a segment of a cylinder or arms, or some equivalent, I consider to be an immaterial part of my invention, so long as the grippers shall be carried from one point to the other and back again, each time receiving a sheet and conveying it to a suitable place of deposit. v

I claim- 1. I do not claim the use of a ily upon which 'a sheet of paper has been previously placed for laying the sheet upon the pile-board, for this is well known; but I do claim the use of rotating reciprocating nippers for such purpose when used either separately or in combination with a rotating reciprocating ly.

2. I do not claim laying the sheet directly upon the platen, in order that it may receive the impression, as this is well known 5 but I do claim relieving the sheet from the type and taking the sheet directly from the platen, or either of them, with or by the same nippers which shall carry such sheet to its place ot' deposit or piling. Y 3. Giving with one inkingcylinder two distributions to the inkingerollers for each impression `viZ., one distribution prior to passing the form and one distribution prior to the return of the form to its first position.

et. lhe arrangement ot' the spring, connecting-rod, crank, and stops, as described, to operate the bed and give the necessary dwell for the impression.
