INKING APPARATUS FOR PRlNTlNG-PRESSES.

SPECIFICATION forming-part of Letters Patent No. 280,127, dated June 26, 1883.

Application filed June 12,1882. (No model.)

To all whom it may concern.-

Be it known that I, JOHN BROOKS, of Plain field, in the county of Union and State of New Jersey, have invented a new and useful Improvement in Inking Apparatus for Printing- Presses; and the following is declared to be a .correct description of the same.

In printing-pressesthe rollers used with the ink-fountain and the composition rollers used to distribute the ink and to spread the ink upon the types are all in contact during the operating of the press, and this is especially so in cylinder-presses. If by neglect any of these rollers are left in contact over. night, their surfaces will become permanently flattened, thereby making them uneven and preventing their uniform action in inking, and ne cessitating recasting said composition rollers. Means have heretofore been devised to separate one or more of the rollers from each other or from contact with the types.

The object of my invention is to separate all of the distributing and composition rollers from contact with each other or the types, or the ink-roller in the fountain, and thereby prevent the surfaces of any of the composition rollers from becoming flattened; and to this end I provide devices for separating these rollers by one movement of a lever or handle in a quick, simple, and efficient manner, and for locking the parts in position both when in use and when separated.

In the drawings, Figure 1 is an elevation of my improved device endwise of the rollers, showing also a part of the frame of a printingpress, the parts being in position for use. Fig. 2 is an elevation of the parts with the rollers separated. Fig. 3 is a partial elevation of the rollers and frame at one end. Figs. 4 and 5 are detached-views of separate parts. Fig. 6 isv an elevation in larger size of the parts shown in Fig. 4. Fig. 7 is a side elevation of the same at one end of the rollers. Fig. 8 is a cross-section in larger size at the line as xof Fig. 2; and Fig. 9 is an elevation in larger size of the cross-shaped frame in its "elevated position, with the rollers separated,

and in its depressed position in dotted lines.

A is part of a frame of a printing-press, which may be of any usual construction; B, the impression-cylinder, and C the bearing for the same; and. D represents part of the type- As the parts hereinafter described are alike on both sides of the machine, it will only be necessary to describe one side.

There are adjustable frames 1) 1) upon the frame a, having tubular sockets c c, for the adjusting screw-rods d d, that carry the journalsof the composition rollers c c, and these composition rollers are the ones that ink the surface of the types. The frame a above these'roller-journals extends as a standard, a and is slotted for the journal-boX of the distributingroller g. At one side of the standard a there is a lock-jaw, f,for a purpose hereinafter described.

There is a frame, h, shaped like a cross and placed against the inner surfaces of the frame a a, as shown in dotted lines, andthis frame is supported by slides on the frame, and can be moved vertically by the toggles '5, link 7.", and lever Z,and is capable of raising the composition rollers c e and the distributor g by acting against their respective journals or boxes. The upper end of the frame first acts against the j ournal-box of the roller 9, raising it out of contact with the rollers c 0. these rollers e c are lifted off or above the types. There is a frame, 011, upon the frame a, guided by and capable of sliding in a dovetailed groove in its upper surface, and this frame at carries the ink-fountain a and inkroller 41/, and this fountain and roller pass across the entire width of the press.

Upon the frame m there is an arm, 0, pivoted or connected, by a hinge'joint at o", to the same, and this arm 0 is provided with a jaw, 0, which receives the journal-box of the transfer and distributing rollers r a", and there is an arm, 2, upon a shaft, the journals of -which pass into the frame m, and this arm passes through the frame 7n and across the Then press, and it has attached to it the pinions 4, which engage in the toothed racks 5, secured to the frame a, so that by turning the handle tthe frame m, ink-trough, and connected parts will be rolled back and forth upon the frames (0.

The back of the frame on has a projection, 6, upon it and av pin, 7 and this pin 7 engages the U-shaped jaw at the end of the lever Z, and this lever Z is pivoted at 8 to the frame a.

The parts as shown in Fig. l are in the position they occupy when the press is working, the handle t being up, the pin 2 caught in the notch 9 upon the frame m, and the jaw 0 of the arm 0 locked into the jaw f of the standard a It is to be understood that these parts, except the lever t t, are duplicated at each end of the ink trough and rollers.

Whenever the press is stopped for a length of time, the rollers should be separated, and for that purpose the attendant grasps the handle t and compresses the spring-lever t, releasing the pin 2 from the slot 9. The handle 25 is now swung down, as indicated by dotted lines, Fig. 1.. This movement revolves the pinions 4 upon the stationary racks 5, causing the frame m and parts carried by it to trc vel back to the position shown in Fig. 2. In this operation the arms 0 and jaws 0 are first drawn back from the jaws f, the slots in the links 8 allowing for this movement, after which the links 8 act upon the arms 0, and swing them and the rollers r 1'' up above the ink-trough and away from the roller 9. The pins 7 swing the levers Z upon their centers 8, and through the links k straighten the toggles 13, and lift the frame h and composition rollers e e and distributingroller g to the position shown in Fig. 2. The composition rollers e e are lifted so that they will be clear of the types in case they are below the rollers, and the distributing-roller g is lifted a little more than the rollers e 0, so as to be separated from them. The handlet in the position shown in Fig. 2 is locked by the pin 2 entering ahole in the side of the frame a. When the press is to be started again, and it is desired to bring the rollers together from their position shown in Fig. 2, the handle it is swung up to the position shown in I Fig. 1, and the pinions 4, revolving against the stationary racks 5 on the inner sides of. the frame a, cause the frame m to travel forward, carrying the links 8, arms 0, and jaws 0 and rollers r 1" down into their proper relative position to the other parts, locking the jaws 0 below the lock-jaw f on the standard a", and lowering the composition rollers e e and distributing-roller g into position and contact with one another. These operations are repeated as occasion may require.

The rollers r and 1* may remain in contact when in the position shown in Fig. 2 but this is not detrimental, as the weight of one roller does not rest upon the other; hence there is no injury to the rollers.

In Figs. 4, 6, and 7 I have shown inverted U shaped arms 12, secured upon the arm 0, and having projecting feet 10 resting upon the top of the journals of the rollers e c. This is done to prevent said rollers e a riding out of their j ournal-boXes when the press is in operation.

The arms 1), (shown in Fig. 5,) that carry the roller 10, are secured 011 a shaft, 12 in the frame m, and this shaft passes from one frame to the other of the press, and I provide an arm, 10, to which is pivoted a slotted link, y, having a roller, 11, and spring 12. The spring 12 forces the arm 20 up, depressing the arm 9 and keeping the roller 19 in contact with the roller 9'.

'Upon and near the end of the type-bed there is a wedge, 13, which in the reciprocation of said type-bed passes over the roller 11, de pressing it and moving the arms w and p, and causing the doctor-roller p to make a short contact with the ink-roller n, to receive from it fresh ink. The arm w is long, and the motion given to the roller 1) is very slight.

I do not limit myself to the specific construction of the various parts for separating the ink-rollers from each other, as changes may be made in the mechanical details.

I claim as my invention- 1. In a printing-press, the frames a a and standard a secured to the frame A of the press, in combination with the moving frame m, the handle, racks, and pinions for moving the same, and the links 8, arms 0, and jaws 0, and mechanism, substantially as described, for simultaneously moving and raising the composition inking-rollers, substantially as set forth.
