JOSEPH A. SMITH, OF FOND DU LAC, AND L. M. ORVIS, OF OAKFIELD, WISCONSIN; ISAAC ORVIS ADMINISTRATOR OF'L. M. ORVIS, DECEASED.

PRINTING-PRESS.

Specification of Letters Patent No; 28,948, dated June 26,1860.

To all whom 'it may concern:

Be it known that JOSEPH A. SMITH, of Fond du Lac, in the county of Fond du Lac and State of Visconsin, and L. M. ORvis, deceased, who resided in Oakield, in the county and State aforesaid, did invent a new and Improved Printing-Press; and we, JOSEPH A. SMITH, and ISAAC ORvis, of Oakfield aforesaid, administrator of the estate of L. M. ORvIs, deceased, 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 l is a side sectional view of the invention, taken in the line m, 0a, Fig. 2. Fig. 2 is a plan or top view of the same. Fig.V 3 is a detached View of the paper-feed ing mechanism.

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

The object of this invention is to obtain a printing-,press for printing from a continuous roll of paper, and possessing automatic mechanism for feeding` the paper to the forms, printing, during one passage through the press, on both sides of the paper, and cutting the same into sheets of the proper length, the paper being also moistened or sponged during the operation of printing.

To enable those skilled in the art to fully understand and construct the invention of the press, aforesaid we will proceed to describe it.

A represent-s a framing, which may be constructed in any proper way to support the workin@ parts of the press.

B is the c riving shaft, which has a toothed wheel, @,at one end of it, said wheel gearing into a corresponding wheel, b, on a shaft, C, and also gearing into a larger wheel, c, on a shaft, D. The wheel, Z), gears into a wheel, (Z, on one end of a crank-shaft, E, and wheel, (l, has a wrist-pin, e, attached to it, which pin is fitted and works in a semi-circular slot, f, in a bar, F, attached to one end of a shaft, Gr. The shaft, G, has two arms, g g, to it, to the upper ends of which bars, h z', are connected by points, j. The inner ends of the bars, 71, z', have ink-rollers, 71: 7s c, attached respectively to them, as shown in Fig. l.

The crank-shaft, E, has two longitudinally slotted arms, Z l, itted on it, one of which is shown in Fig. l, and the up-per ends of these arms are attached to a bar, II, the:V ends of which are fitted between guides, m, at the sides of the framing, the bar being allowed to work freely up and down.

To the upper surface of the bar, H, a bed, I, is attached which receives a form, a, and in the framing just above the bed, I,

there is placeda plate, J, which forms a bedfor another forni, 0,. (see Fig. l), the plate or bed being allowed to rise and' fall in the framing. 0n the top of the framing and directly over the bed, J, there is a plate,K, which has uprights, p, attached to it, to form supports or bearings for rollers, L M, 7'.

To one edge of the plate, K, there are pendent bearings, s s, attached to support a roller, t, and a similar roller u, is attached to one end of the bed, J, the roller, a, being just'below the roller, t. Ink rollers, u o o, are placed in proper supports or bearings on the upper part of the framing, and there is an ink-roller, w, on the shaft, B.

N is an endless blanket which `passes between the rollers, M, 1', and underneath the plate,'K. The roller L, has the paper, O, wound on it in a continuous sheet.

In the framing, A, and just below the outermost ink-roller, fv, therea-re placed two rollers, lw fwf, one of which, fw', has a ratchet, a, at one end of it, said ratchet being connected by a pitman, b, witha pulley, o', at-one end of the roller, M, there is a pulley, c, which has a pitman, b, attached to it, said pitman being attached toa ratchet, a, at the end of roller w', opposite to that which has the ratchet, a', attached. The pitmen, b b, are connected to their respective pulleys and ratchets at different point-s in order to insure a simultaneous movement of the rollers, fw w, and M, r. The ratchet, a', has a holding pawl, cZ, whichengages with it and the ratchet, a, has a pawl, e', which engages with it, the pawl, e, being attached to a circular plate, O", which is placed loosely on the shaft of roller,w, and has a pinion f', secured concentrically to its inner side. This pinion, f', gears into a toothed segment, l?, attached to a radius shaft, Q, which is connected by a rod, g', with one of the arms, g, of shaft G-see more particularly Fig. 3.

On the shaft, D, a spiral cutter, R, is placed, and this cutter, as shaft, D, rotates,

has its cutting edge working over the edge of a bar, S, in the framing, and this bar, S, may be considered as a stationary cutter.

The paper, O, passes from the roller, L, between the rollers, M r, around and underneath the plate, K, over the rollers, t, a underneath the plate, J, and between the rollers, lw fw, and down over the bar or stationary cutters, S, as shown clearly in Fig. l.

rI`he operation is as follows: The shaft, B, is rotated by any convenient power, and motion is communicated therefrom to the crank shaft, E, by the gearing, a b CZ, and the slotted arms, Z, are intermittingly raised by the rotation of crank shaft, E, the beds I, J, being, of course, raised by said arms, the bed I, raising bed J, the under side of which serves as a platen to bed I, the plate K, serving as a platen for bed J. The ink-rollers 7c, 7c, c, c, are also intermittingly moved through the medium of the wrist pin, e, and slotted bar, F, and said rollers have the ink distributed on them from the rollers t, w, the latter being supplied with ink in the usual, or in any proper way. The rollers 7c, It, c, 7c', are moved over the forms a, o, and ink them when the latter are drawn over free from the paper, and the impression is given the paper at the termination of the upward movement of the beds I, J. The paper, O, passes between the rollers M, r, underneath the blanket N, under plate K, around the rollers t, a, and consequently underneath the plate K, and bed J, and then between the rollers w, fw, and down between the bar S, and shaft D. The paper O, is moved intermittingly through the medium of the rod g', segment I), pinion f, pawl e, ratchets a, a, on shaft fw', on the pitmen Z9', which connect the ratchets a, a, with the pulleys c', c, of roller M. The paper is moved in the direction indicated by arrow l, the segment P, when moving in the direction indicated by arrow 2 rotating the shaft w', the pawl e, slipping over its ratchet a, when the segment moves in the opposite direction. The paper is moved a distance at each impression, corresponding to the length of the form, and the feed movement may be varied as occasion may require by adjusting the rod g', in either of a series of holes in the arm g, to which it is attached. The paper, of course, is moved during the downward movement of the beds I, J, and is stationary when the beds I, J, are moved upward to give the impression, one form 1t will be seen prints one Y side of the paper and the other form prints at the opposite side. The cutter R, on

shaft D, cuts the printed sheets from the paper connected with the roller as the sheets pass down'between the bar S, and cutter R, the rotation of shaft D, being such as t0 commence its action at the proper time to divide the sheets at the centers of the margins between them. The endless blanket N, is moistened and kept in a damp state during the operation of printing, in order that the paper may be sponged or be dampened sufficiently to readily receive the ink, the paper receiving the moisture from the blanket by the pressure which accomplishes the printing.

Having thus described the invention of JOSEPH A. SMITH, and L. M. ORVIS, deceased,

we JOSEPH A. SMITH, and ISAAC ORvIs, administrator of the estate of L. M. ORvIs, deceased, do claim as new and desire to secure by Letters Patent, respectively, as an inventor and administrator in trust for the heirs of L. M. Davis, deceased l. The arrangement of the form beds I, J, and stationary platen K, substantially as shown, so that the impression may be given simultaneously and by the same application of power, and the under side of the upper form be made to serve as a platen for the lower one.

2. The arrangement of the form beds I, J, and platen K, with the roll of paper O, sub stantially as shown, and operated respectively and intermittingly so that the paper may be printed from a continuous sheet, and at both sides during a single passage through the press.

3. The endless wet blanket, N, arranged to pass underneath the platen K, and to be moved simultaneously with the paper O, for the purpose of moistening the same during the pressure which causes the paper to receive the impression from the forms.

4. The ink-rollers 7c, 7c, c, la', operated through the medium of the bars zf, t, arms g, rockshaft G, the slotted curved bar F, and wrist pin e, on wheel d, when said rollers are used in connection with the form-beds I, J, and platen K, as set forth.

5. The combination of theform-beds I, J, platen K, endless blanket N, ink-rollers lo, 7c, it', c, paper roll O, rotary knife R, and stationary bar S, all arranged for joint operation, as and for the purpose set forth.
