HAND PRINTING-PRESS.

Specification of Letters Patent No. 24,655, dated July 5, 1859.

To aZZ whom it may concern.'

Be it known that we, A. NEWBURY and B. NEwUnY, both of Windham Center, in the county of Greene and State of New York,

have invent-ed a new and Improved Printing-Press; and we 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 longitudinal vertical and central section of our invention. F ig. 2, a plan or top View of the same.

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

To enable those skilled in the art to fully understand and construct our invention we will proceed to describe it.

A, represents a. frame which is properly secured to a platform or base B, and a, a, are two parallel bars placed on the upper part of said frame, one at each side. On the upper part of the frame A, the form bed C,

is placed, the bars a, a, in connection-with traverse pieces Z2, ZJ, forming sides to the bed.

D, represents the type or form placed on the bed C, and locked within the sides or bars a, a, and traverse pieces Z), b.

E. represents a frame, which is formed of two parallel bars c, c, the lower or inner parts of which are bent about at right angles to the upper or outer parts. rllhe outer paris of the bars c, c, are connected by a bow or curved bar (Z, which has a handle e, attached. The bars c, at their loweror inner ends are fitted loosely on the shaft e, which is below the form bed C.

F, is a platen one end of which is provided with arms f, f, one at each side. These arms are fitted loosely on a transverse shaft y, on the frame A. The platen F, is of rectangular form and corresponds in size with the form bed (l. To the upper surface of the platen F, a` bar G, is attached. This bar is fitted in guides ZL, attached to the back of the platen and may be adjusted by set screws a', according` to the pressure required. On each end of the bar G, a friction roller ji is placed, and these friction rollers are fitted in longitudinal slots Zr, in the bars o, o, of the frame E.

H, is a frisket, one end of which is provided with arms Z, Z, which are fitted loosely on the shaft g, precisely similar to the arms f, f, of the platen F. This frisket is a rectangular frame which is made to fit around the platen. To the arms Z, Z, of the frisket, the upper ends o-f spiral springs m, m, are attached. The lower ends of said springs being attached to the platform or base B.

To one of the bars c, of the frame E, a rod is attached, said rod being also attached to a frame I, which is placed on a rock shaft J, on the platform or base B. To the upper end of the frame I, two rods o, 0, are attached, at one end and these rods are attached at t-he opposite end to a roller frame K, which rests on the bars a, a, said frame being provided with proper ink rollers.

L, is a circular table, the upper surface of which is on a level with the face of the form D. This table has its arbor fitted loosely within a socket or support M, and to the under side of the table and concentric with it, a ratchet g, is attached. On the arbor of the table L, an arm N, is placed loosely, and to this arm a pawl 1", is attached and kept in gear with the ratchet 1, by a. spring s. To the outer end of the arm N, one end of a rod O, is connected, the opposite end of said rod being tted in the upper end of a bar t, at.- tached to the rock shaft J, the rod having pins a, passing through it one at each side of the bar t.

l?, is a spring the lower end of which is attached to the platform or base B, the upper end being made to bear against the table L.

Then the press is used for printing cards, the frisket H, is permanently attached to the platen by hooks c, la, and twoguide bars a, a, are attached to the frisket and eX- tend over the inner surface of the platen. Between the arms Z, Z, of the frisket H, a shaft Q, is fitted, and on this shaft two sockets b', are placed. In each socket b, a bent plate or strip c, is placed, the ends of said plates or strips are bent upward to form stops. The bars a', a', may be adjusted nearer together or farther apart according to the length of the cards to be printed.

On the shaft g', an arm (Z, is secured by a set screw e', and to the shaft Q, an arm f, is attached at right angles, said arm having a spiral spring g, connected with it, which spring has a tendency to keep the stops c', against the face of the platen.

The operation is as follows :*The table L, is supplied with a requisite quant-ity of ink. The form D, locked on the bed C. If the frame E, is in an elevated position as shown in red Fig. 1, the platen F, will be raised, and the ink rollers in the frame K, will be at the inner side of the form D, having passed over the form as the frame E, was elevated. As the frame is depressed by the operator, ablank card is inserted between the guide bars a, a', and the platen F, is forced down by the downward movement of the frame in consequence of the rollers j, y',

tting in the slots lo, 76, of the bars 0, 0, of the frame. As the platen F, descends the roller frame K, is moved outward over the form D, and table L, by the rod a, frame I, and rods 0, 0, the form being properly inked by the passage of the roller over it. rlie card is pressed down upon the form D, and receives its impression by pressingY down the frame E. As the frame E, is raised, the roller frame K, is moved inward over the table L, and form D, and as soon as the roller frame leaves the table and passes on the form D, the table L, will be rotated a certain distance by the pawl r, acting against the ratchet g, the pawl r, being actuated at the proper time by the rodO, and bar t. This intermittent rotation of the table L, causes the ink to be distributed evenly on the rollers in the frame K. 'J ust previous to the platen F, reaching the end of its upward movement, the arm f', on the shaft Q, strikes the arm d', on the shaft g, and the plates or stoops will be thrown out from the face of the platen and the printed card thereby allowed to fall out by its own gravity, between the lower ends of the guide bars a, a.

r The frame E, is then again depressed, an-

other blank card inserted between the guide bars'a, the plates or strips c, being thrown against the face of the platen by the spring g, to stop the card, as the arm F, leaves the arm d.

In case bills or ordinary sheets are to be printed, the bars a, a, and the plates or strips 0', c, are removed. The hooks fu, fv, are also removed so that the frisket H, will not be attached to the platen F,-the arm cZ, is adjusted toabout the center of its shaft g. The operation of printing the paper sheets is precisely the same as that of printing the cards, with the exception that the frisket H, is moved instead of the plates or strips c. The frisket being opened or thrown out from the platen as the latter reaches the termination of its upward movement in consequence of the arm cZ, bearing against the shaft Q. The blank sheet to be printed is consequently placed between the frisket and platen at the commencement of the downward movement of the same, the printed sheet being previously removed. As the platen F, descends the springsvm, m, cause the frisket to move inward around the platen and grasp the sheet.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is:

- The arrangement and combination of the slotted frame E, adjustable bar Gr, platen F, roller frame K and rot-ating ink table L, substantially as and for the purposes herein shown and described.
