PRINTING-BLOCK.

SPECIFICATION forming part of Letters Patent No. 523,307, dated July 1'7, 1894.

Application filed May 10, 1893. Serial No. 473,721. (No model.)

To aZZ whom it may concern:

Be it known that I, FREDI. GETTY, a citizen of the United States of America, residing at Springfield, in the county of Sangamon and State of Illinois, have invented certain new and useful Improvements in Printing-Blocks, of which the following is a specification.

My invention relates to improvements in printing blocks, its object being to provide a practical self-inking device adapted to be set in an ordinary form of type and to print on the paper upon the impression roller an impression in any desired color, the printing surface of the device being so arranged as not to be acted upon by. the inking rollers, which act upon the general surface of the form.

The device is fully described and explained in this specification and shown in the accompanying drawings, in which- Figure l, is a top plan of a device embodying my improvement. Fig. 2 is a side elevation thereof, the view being in the direction indicated by the arrow, m, Fig. 1. .Fig. 3 is a view partly in end elevation, and partly in transverse vertical section, the view being in the direction indicated by the arrow, or, and the plane of section being through the line 3-3, Fig. 1, the end wall, A of the case being removed. Fig. 4 is a view partly in side elevation and partly in longitudinal vertical section, the View being in the direction indicated by the arrow, at, Fig. 1, and the plane of section being through the line t -4., Fig. 1. Fig. 5 is a view partly in side elevation, and partly in longitudinal vertical section, the view beingin the same direction as in Fig. 1, and the plane of section being through the line 5-5, Fig. 1. Fig. 6 is a longitudinal vertical section through the line 66, Fig. 1, the

view being in the same direction as in Fig.

5. Fig. 7 is a horizontal section through the line 77, Fig. -5, the view being downward. Fig. 8 is a view partly in side elevation and partly in vertical section, the view being in the same direction as in Figs. 2,4, 5 and 6, and the section being through the broken line 8-8, Fig. 1. Fig. 9 is a view similar to Fig.

5, except that in this figure the plates, B, B,

are pressed down to their lowest limit of motion, and the frame, 0, is raised to its highest limit of motion, whereas in all the preceding figures, the plates are in their highest position and the frame is depressed. In this fig ure alsothe parts beneath the frame, 0, are removed in order to show the spring-actuated rod, R, at the farther side of the case.

In the views, A, A, A A? are the side and end walls respectively, of a case provided with a bottom piece, A and containing and supporting all the working parts of the mechanism of my invention this case being adapted to be set in an ordinary form of type and its upper margin being preferably lower than the face of the form. Immediately within the side walls, A, A, of the case are two vertically reciprocating plates, B, B, having no direct connection with the walls of the case but supported in the manner hereinafter explained, and between the plates, B, B, lies a vertically reciprocating frame, 0, containing and supporting various elements of my mechanism. Between. each of the plates, B, B, and the frame, O, are two levers, L, L, lying in recesses in the inner face of the plate and swinging on pivots, P, P, set in the corresponding side walls, A, A, of the case. Each of these levers is approximately triangular and is made up of three arms, Z, Z, Z the arms, Z, Z, being at the upper edge of each lever and the pin, P being very nearly on a line between them. Each of the plates, B, B, is provided with two pins, P, P, projecting from its inner face and pivoted in the ends, Z, Z, of the two corresponding levers, L, L, and each. side wall of the frame, C, is provided with two projecting pins, P P, which are pivoted in the ends, Z, of the corresponding pair of lovers, L. The lower ends, Z of the pair of levers at each side are connected by a rod, R, Figs. 4 and 9, encircled near one of its ends by a collarm, and extending at its opposite end int-oayoke, R, lying in a longitudinal slot in the bottom A, of the case providedwith a pin, r, entering a socket in the end wall, A of the case. The rod, R, is encircled by a coiled spring, S, lying between the collar, 1', and the yoke, R, and tending to press the collar, 1", the rod, R, and the lower ends, Z of the levers in the direction indicated by the arrow on the rod in Fig. I.

The tension of this spring may be varied by means ofa set screw, 8, Fig. 4, forming the end wall of the socket which incloses the pin, "1'', the yoke, R, being susceptible of slight longitudinal adjustment in the slot in which it lies, and the force of the spring evidently tends at all times to raise the angles, Z, Z, of all the levers and depress the angles, Z, thereof, and thus to raise the plates, B, B, and depress the frame, G. The plates, B, B, may, however, be pressed down with suliicient force to rock the levers upon their pivots and overcome the force of the springs, S, S, and this movement of the plates will correspondingly raise the frame, 0.

The plates, B, B, are of such width and are so located in the case, A, that when the latter is set in a form of type, the upper margins of the two plates are above the face of the form and are in position to receive the downward pressure of the impression cylininder as the form passes under it, the plates I being thereby depressed to produce the results above set forth.

Within the frame, C, and rigidly but de' tachably secured to its side walls are two plates, D, D, in contact with the inner faces of the corresponding walls, 0, C, of the frame. Between the central portions of the plates, D, D, is a block, E, having its ends recessed as shown in Fig. 6, and in these recesses lie two cylinders, F, F, mounted on parallel ar bors, f, f respectively, both the arbors being journaled in the plates, D, D, and the arbor, f being of such length that its ends project beyond the plates, D, D, and lie in notches, c, c, in the walls, 0, O, of the frame.

The plates, D, D and the block, E, are preferably fastened together by means of horizontal screws passing through the plates and entering the block in the manner clearly shown in Fig. 7, and the plates are detachably secured in the frame, C, for the reason that it is more convenient to assemble the plates and the parts between them before placing them in the frame.

On the ends of the arbor, f, are rigidly mounted two pinions, G, G, each of which engages a gear-wheel, G, lying in a recess in the outer face of the corresponding walls 0, and O, and mounted on fixed studs 8, Figs. 5 and 9, set in said walls. Each of the gearwheels, G, has on its outer face a rigidly attached concentric pinion, G which engages a gear-wheel, G mounted on a stud, 3 set in the corresponding side walls of the case, 0, and having in its outer face an annular ratchet, as shown in Figs. 7 and 9. On each of the studs, 8 is mountedalever, L, formed on its inner face with an annular ratchet engaging the ratchet on the gear-wheel, G the ratchet being so formed as to permit rotation of the lever, L, with reference to thegearwheel, in the direction indicated by the arrow on its face in Fig. 9, but not in the opposite direction. A spring, 3', encircles each of the studs, 3 and presses the lever against the the gear-wheel, thereby tending to hold the ratchets in engagement. Each of the levers,

L, has in its free end a slot which embraces a pin, P, on the inner face of the correspond ing plate, B, or B, and at every vertical movement of the plate, which is accompanied by an opposite vertical movement of the frame, 0, 0, each of the pins, P swings the corresponding lever, L, about the stud on which it is mounted. When the plates are pressed downward, they swing the ends of the levers, L, downward also, and the ratchet connection between the levers and the gears, G permits the levers to move in this direction without rotating the gear-wheels. When the plates move upward, however, they swing the slotted ends of the levers upward and impart to the entire train of gearing, G G G G, on each side of the frame, 0, O, the movements indicated by the arrows on the different gearwheels, respectively, in Fig. 5, thus rotating the drum, F, in the direction indicated by the arrow at its margin in Fig. 6.

The drum has at one end a rigidly attached ratchet-wheel, F which engages a springactuated pawl, 12, pivoted in a recess in the side wall of the block, E, and adapted to prevent reverse rotation of the ratchet wheel, and the drum, F. About the two drums, F, F, extends an endless band, H, whose upper and lower folds are always in contact with the upper and lower plane faces of the block, E, and on this band are formed two suitable printing surfaces, each preferably adapted to cover substantially the entire upper face of the block, the spaces between the two printing surfaces at either end being substantially equal. l

Beneath the frame, (J, C, is an inking pad, I, of suitable material and construction to ink either printing surface of the band, II, when pressed against it, and this pad may either be in a single piece, or in two pieces as shown in Fig. 6, the two parts of the pad being preferably supplied with inks of different colors, so that each printing face, in use, may make an impression in two colors instead of one. The gearing which actuates the drum, F, is so arranged, and the circumference of the drum is such that during each upward movement of the plates, B, B, and the accompanying downward movement of the frame, 0, O, the band moves through a distance equal to one half of its entire length, so that the two printing surfaces of the band come alternately into the same position on the upper face of the block, E, and are presented alternately to the paper on the impression cylinder of the press.

The gearing may be so arranged as to operate during each entire downward move ment of the frame, 0, C, but I prefer to arrest the rotation of the drums, F, F, and the consequent movement of the band, H, just before the frame reaches its lowest position, as by this arrangement any dragging of the band along the inking pad is prevented. In order to accomplish this, the pinions, G, G, and their shaft, f may be'disconnected from the drum, F, at a predetermined point in the downward movement of the mechanism, and an arrangement by which this connection may be efiected is shown in Figs. 6 and 7. As shown in these figures, the drum, F, is a hollow cylinder open at one of its ends, the open end being filled, however, by a hub, F formed on the ratchet wheel, F and provided on its inner end with aface-ratchet as shown .in Fig. 7, the hub being held in place by a set screw inserted in the wall of the-drum.

On the shaft, f, is rigidly mounted a sleeve, F provided with a ratchet engaging the ratchet on the hub, F?, and a spring, S encircling the shaft, f, tends to press the sleeve and the shaft toward the hub, F and maintain the engagement of the two ratchet-faces. In the side wall, of the frame, 0, O, is mounted a horizontally oscillating lever, L

whose inner end is in contact with the outer face of the corresponding pinion, G, the outer end of the lever being in contact with a vertical lever, L Fig. 3, which is pivoted on a pin set in a plate, L Fig. 7, secured in a recess in the inner face of the end wall, A of the case, the lever being fastened to the removable plate, L instead of being pivoted directly to the wall, A simply as a matter of convenience in assembling the parts. This lever lies between the end of the lever, L and apin, P set in the end wall of the frame, 0, O, and is of less width in its upper than its lower portion. Y

When the frame, 0, O, is in its lowest position, or in a position slightly above its lowest limit, the wider portion of the lever, L lies between the pin, P and the end of the lever, L and the outer end of the lever, L is therefore pressed outward, and its inner end pressed inward with sufficient force to overcome the spring, S and disconnect the ratchet-face of the sleeve, F from the ratchet-face on thehub, F When the parts are in this position, the gearing rotates without affecting the drum, and the band, H, has, therefore, no longitudinal movementduring the last part of the downward movement of the frame, 0, C, and the parts within it. As soon as the frame has moved upward a short distance from its lowest position, the outer end of the lever, L reaches the thinneror narrower portion of the lever, L and is free to swing inward, its inner end being at the same time pressed outward by the force of the spring, S and the shaft, f, being again connected with the drum, so that rotation of the gearing may again rotate the drum. When thelever, L

and pin, P in their upward movement, reach the narrower portion of the lever, L the lat-- ter swings about the pivot in its lower end and moves toward the pin, P thereby increasing the range of lateral movement of the'lever, L as compared with that which it would have if the lever, L were rigidly fastened to the end wall of the case instead of being allowed to' oscillate upon a pivot. From this description and explanation, it will be seen that as the plates, B, B, move downward, the frame, 0, O, and the parts within it rise, the drums, F, F, being stationary with reference to the frame; and that during the reverse movement of the parts, the drums, F, F, rotate, and the band, H, moves longitudinally until the downward movement of the block is nearly finished when the drums become stationary, and the band is pressed directly down upon the inking pad.

In order to arrest the movement of the band at exactly the right place and guard against any error from the momentum of the drums, I have found it advisable to provide the band with laterally projecting pins, or wires, to, Figs. 1 and 6, which are adapted to strike suitably placed pins, P Figs. 3 and 6, set in edges of the pad and adapted to be struck by the wires, 'w, when the block, E, is approximately at the lowest limit of its movement.

The case which contains the working parts of my device is thesame as that shown in my prior application, Serial No. 443,500, and the plates, B, B, the frame, 0,0, and the rocking levers connecting the case, the frame and the plates are all substantially the same, and in the same relation to each other as the corresponding parts of the device shown and described in that application. Those elements of the mechanism shown and described herein constitute, therefore, in themselves no part of my present invention, though they co-operate with the novel elements to make up a practical working device.

It is evident that as the plates, B, B, move up and down at the same time and at the same rate, they might be rigidly'connected without altering their function or operation, and it may be found desirable to connect their ends by transverse plates making up with them a rigid frame. The upper edges of this frame may, if desired, be ornamented in any suitable manner in order to print a design in ink of the same color. as that which-is applied to the type of the form in which the block is set,

and, in fact, the upper edge of the frame may be detachable and may be formed with letters or other characters adapted to print an advertisement, which'may be changed by removing such upper portion and replacing it by another having a different design or different characters. The inkingpad which is shown in two parts may evidently be made up of any number of different parts held tolength, and means for imparting longitudinal movement to the band about its supports, the frame when in one position being adapted to press the exposed fold of the hand against a suitably supported sheet and produce an impression thereon.
