GEORGE P. FENNER, OF NEW LONDON, CONNECTICUT.

INKING ARRANGEMENT FOR PRINTING-PRSSES.

Specification of Letters Patent.

Patented March 5, 1907.

Application led April 24, 1906. Serial No. 318,496.

To all whom t may concern,.-

Be it known that I, GEORGE P. FENNER, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented new and useful Improvements in Inking Arrangements for Printing-Presses, of which the following is a specification.

This invention relates to an inking mechanism or device in which is arrangedan additional form-roller so as to allow a larger form to'be inked than could heretofore be accomplished without increasing the size of the press.

This invention is set forth 'in the following speciiication and claims, and illustrated in the annexed drawing, in whichh Figure l is a side elevation showing the press-bed at the front end of its travel; Fig. 2, an end view of Fig. 1. Fig. 3 shows the ink roller and fountain removed away from the cylinder to admit of convenient handling and adjusting of the ink-rollers. Fig. 4 is an enlarged view of details of the inking mechanism or device. Fig. 5 is a section along line Fig. 4. Fig. 6 shows a modification in which the inking mechanism is connected by a cam to its setting-lever instead of by a link connection, as in Figs. l and 3. Fig. 7 shows the additional form-roller driven by gears instead of by mere contact, as in Fig. l. Fig. 8 is a front view of Fig. .7. Fig. 9 shows bearings for giving stability to the supplemental form-roller. Fig. 10 is a plan view of part of Fig. 7.

In Figs. l, 2, and 3 the roller-bearings have been removed to expose certain parts.

The press-bed is shown at d and the tworoller inking mechanism or device is shown at l) and t. An additional small form-roller is shown at b2 and is arranged to occupy space on a large single-revolution cylinder-press, which s ace has heretofore been waste room, and it as been one of the weak points of such presses, because if the type moves far enough to go under both of the large rolls b and b it increases immediately the diameter of the cylinder to admit of the eXtra travel of the bed, and the increased diameter of the cylinder again pushes the rollers farther out, which makes it necessary to further increase the size of the press, or, in other words, this inking arrangement makes it possible to ink a much larger form than could heretofore be accomplished without increasing the size of the press.

There is a small portion of the type between rollers b and b which is not inked with three rollers; but this space is so small that the inking is as perfect as if three rolls passed over it.

Form-rollers o and b are of the same size. The roller b2 is a composition form-roller of small diameter, and said roller b2 is driven by surface Contact with roller b through a small steel ink-cylinder b3.

With this arrangement it is seen that rollers b/ and b2 pass completely over the type. The roller b does not pass clear across or over the type, but at the position or point shown in Fig. l is raised from the type slightly, so that it does not reverse on the form, but remains in contact with the large vibrating cylinder c and is thus kept in motion.

The rollers are shown mounted or supported on abracket or carriage h, which is moved to throw the rollers one way or another. This carriage or stand h is connected or linked to arm fi, which can be swung by a lever d.

The ink-rollers are thrown forward by the hand-lever d, which has a collapsible eXtension d, thus allowing the extension to slide down out of the way when not in use. When the lever d is thrown into the position indicated in Fig. l, the ink-rollers are locked in their proper position for inking the type.

There is a wedge-clamp e on the foot of each ink-roller bracket or stand, so that when the ink-rolls are in position shown in Fig. 1 they are locked positively in position.

In position shown in Fig. l the link d2 is thrown on to the center, and thus locks the ink -roller stands positively in position. This, together with the wedge-clamp, holds them securely.

The wedge f, carried by the type-bed, is shown in Fig. 4 as having raised form-roller l) o'li` the type, so that such roller does not reverse on the type, as before mentioned. The bearing or .axle of this roller is raised by the slides or stems 7c, which by screws m can be suit ably held or raised to required position in sleeves o, having slotted extensions clamped in proper position by screws or jam-nuts p. The bearing or levers g, carrying sleeves o, are pivoted at r, and their rollers s are raised by the wedges f to lift the form-rollers. A retmning-spring for a lever or arm is shown at t.

The journals of the form-rollers are shown supported in eccentric roller-bearings of the IIU usual type on the market. bearing to one position or another the roller can be thrown out of or into contact. Eccentric bearings are shown at g and g3. Inkcylinder b3 is held in the eccentric bearing g, by which it can be easily thrown out of contact with both form-rollers. This eccentric bearing is of the usual kind comprising a circular ring or seat with a corresponding circular disk thereon, and which disk is mounted eccentrically about the aXis of rotation of the cylinder. This disk is in the shape of a bushing, and such disk can be withdrawn endwise or slipped olf the shaft of cylinder b3,

so that the small ink-cylinder b3 can be immediately removed from its bearings.

The spring-catch g serves to hold the eccentric bushing g in position in both directions-- that is, it prevents the bushing from pushing out endwise-and also holds it in its correct rotary position by dropping into the notches in the surface of the bushing. These notches or recessed portions of the bushing are shown in the circumference thereof in Fig. 4, and the catch g has a shoulder or projection adapted to engage into one or another of the recessed portions. As the catch engages suoli a recessed portion the bushing g is held against rotation or turning, so that the roller or cylinder b3 is maintained at a certain level or position relative to the rollers b and b2. This is a complete and satisfactory locking arrangement that is easily manipulated. The spring for the catch is shown at yt g to be turned or' set.

The small roller b2 has not as much inkingsurface as roller b', but in connection with this small cylinder b" the combined surfaces of the rollers b2 b3 will have an area at least equal to the area of the surface of roller b. Hence the roll l) is practicall an additional inking-surface and as roll dpasses nearly over the type, it makes the whole apparatus almost equivalent to a press with three inkrollers passing clear over all the time.

The device has been found satisfactory as compared with the usual two-roller arrangement and increases the speed of the machine materially, also by the sliding front arrangement, which is accomplished with lever d, the device ismore conveniently operated than heretofore with the ordinary tworoller arrangement.

It is obvious when the wedge-clamp e is properly adjusted and the hand-lever d is thrown into the position shown in Fig. l the ink-rolls stand squarely across the press and are held positively against motion in any direction, and the simple changing of the -lever d, which can be accomplished without loss of time, is all that is required for bringing the rolls into or out of action.

In the modification shown in Fig. 7 the roller b3, instead of being driven only by con- By turning the The stem or handle 2 enables the bearing tact with the composition rollers b andb?, is driven by gear 3. This gear receives power from gears 4, actuated by gear 5, whose shaft 6 has a gear 7, Fig. 8, actuated by the vibrator-rack on the edge of the bed a. Jointed arms are shown at 8 for suspending the gears. The gear 3 is shown connected to one endof roller b3. The other end of this roller can be left plain or not provided with any gear. To adjust the roller b3, one of the gears 4 is removed, so as to allow easy action in sliding or moving the roller in any direction, so that while adjusting no rotary motion is communicated to roller b3, which would make the movement hard. The gear 4, which is 1n mesh with gear 3, is removable on withdrawal of the Cotter-pin 9, Fig. 7. The inside bearings 10, one of which is on each side of the press, are to support and give stability to the steel or supplemental roller b3. These inside bearings can be pressed down or out of contact with the roller and held out of contact by the clamp or holding screws 1 1. When the roller is adjusted, the clampscrews are slackened, and the springs l2 throw the bearings into ositive and firm contact with the shaft of roller b3. Then by tightening the clamp-screws the inside bearings are immediately set positively in the eX- act position and with just enough ttension on them to impart great stability to roller b3. As soon as roller?)3 is properly set the little intermediate gear which is held in position by the cotter-pin is replaced. The object of removing this as stated is to lallow easy action in sliding back or u and down the bearings which support rol er b3. Otherwise, if the little gear is not removed, a rotary motion is imparted to b3 every time it is moved, which makes it move hard, and thus it is not easy to set it accurately.

Another modification is in the mechanism of throwing the ink rolls or carriage h close to the cylinder and away from the cylinder. Fig. 3 shows a plain link and lever. In Fig. 6 is substituted a cam d2, which cam is so shaped. that the inking arrangement is locked positively in its outward position, as well as in its inward position, in which case it is entirely feasible to run the press with the inking arrangement in either position.

What I caim as my invention, and desire to secure by Letters Patent, is-

1. A cylinder and type-bed combined with a small or supplemental ink-roller made to sit close between the surface of the cylinder and bed, a bracket or carriage for the rollers, a wedge-clamp at the foot of the bracket or stand to hold the latter in place and means for shifting the bracket.

2. A cylinder and type-bed combined with a small or supplemental ink-roller made to sit close between the surface of the cylinder and bed, a bracket or stand for the rollers, a clamp for the bracket, a shifting lever for the IOO TIO

IZO

mental ink-roller, bearings for the roller,

springs for normally moving the bearings to the roller and clamp-screws or holders for 15 keeping the bearings out of action and leave the roller free for adjustment.

In testimony whereof I have hereunto set my hand in the presence of tWo subscribing Witnesses.
