INKING APPARATUS FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented April 23, 1907.

i Application filed July 13, 1904:. Serial N0. 216,344:-

To (LZZ whom, it puny concern.-

Be it known that I, FRANCIS MEIsEL, a citizen of the United States, residing at Dorchester, in the county of Suffolk and State of Massachusetts, have invented a new and. useful Inking Apparatus for Printing-Presses, of which the following is a specification.

This invention relates to an inking apparatus which has been especially designed for use upon bed-and-platen printing-presses.

The especial object of this invention is to 'fication.

In the accompanying drawings, Figure 1 is a side view of sufficient parts of a printingpress to illustrate the application of my invention thereto. Fig. 2 is a side view of the connections for operating the distributorroll, and Fig. 3 is a plan view of the parts illustrated in Fig. 2.

In the accompanying drawings I have illustrated my invention applied to a bed-andp'laten printing-press of well-known type; but it is to be understood that so far as a certain part of my invention is concerned the same may be applied to printing-presses of different classes.

Referring to the accompanying drawings and in detail, A designates one of the side frames of a bed-and-platen printing-press.

- Mounted upon the side frames A is the mclined platen B. Pivoted at one end of the machine is the swinging bed P which cooperates with the stationary platen B. The web or strip of paper is led up over the platen B and. may be printed on upon one side by a form of type or plate carried by the swinging bed P.

The parts thus far referred to are arranged in a well-known manner and need not be herein described at length.

The inking apparatus for inking the form of type upon the swinging bed P is carried by and moved. with the swinging bed.

As shown in Fig. 1, 1.0 designates a shaft of the printing-press, which may be driven in I per ink-drum D.

any of the usual or ordinary manners. Mounted on the shaft 10 is a sprocket-wheel, which is connected by a driving-chain 1.1 to a sprocket-wheel mounted upon the shaft 12, which forms the pivot of the swinging bed P. Turning with the driven sprocket-wheel is a sprocket-wheel which is connected, by means of a driving-chain 13, to turn a sprocketwheel 14. Carried by the sprocket-wheel 14 is a gear 15, which, through anintermediate, drives gear 16 of the lower ink-drum D. The gear 16 is connected by a train of four intermediate gears to drive the gear 17 of the up- Cooperating with the ink drums D and D are the usual form-rollers R R, which are carried by swinging arms for inking the forms of type placed upon the bed P. The connections for operating the formrollers may be of the same construction as ordinarily employed in this type of printing press and need not be herein described in detail. By means of this construction it will be seen that by using two sets of chains and sprocket-wheels I have rovided very simple and direct connections for operating the inking apparatus and that these driving connections do not interfere with the turning or swinging of the movable bed.

Secured on the shaft of the upper inkdrum D is a small gear 18, which meshes with and drives the gear 19. The gear 19 is connected by special connections to reciprocate a distributer-roll I. These special connections are illustrated in Figs. 2 and 3. As shown in Fig. 3, the gear 19 is provided with dovetailed ways, mounted. in which is an ad justable nut 20. Threaded into the adjustable nut 20 is a bolt 21, which serves to fasten the nut in different adjusted positions. EX- tending from the bolt 21 is a link 22, pivotally connected at its'opposite end to a yoke 23, pivoted to the short arm of the bell-crank lever 24. The other arm of the bell-crank lever 24 is provided with a yoke having pins engaging a groove in a wheel turning with the distributer-rollI. By means of this construction it will be seen that I have provided adjustable connections for reciprocating the distributer-roll I and that by setting the bolt 21 at different positions different lengths of travel may be imparted to the distributerroll. I consider this a particularly desirable construction, and it is one which is adapted for use in connection with other different styles of printing-presses-from that herein shown.

By varying the length of stroke of the distributer-roll I am enabled to vary the character of the ink distribution, while in addition to this the provision of avariable travel for the distributer adapts the distributerroller for distributing inks of'a number of different colors. For example, where the fountain is divided into a number of different sections, different-colored inks may be distributed so that the several colored inks will not be blurred or run together.

I am aware that changes may be made in practicing my invention by those who are skilled in the art without departing from the scope thereof as expressed in the claims. I do not wish, therefore, to be limited to the particular construction I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is

1. In an inking apparatus for printingresses, the combination of inking-rolls, a aterally-movable distributer-roll, operating connections for the distributer-roll compris- 2 5 ing a bell-crank lever having one arm connected to the distributer-roll, a pivoted yoke and pitman connecting to the other arm of the bell-crank lever, and a crank-pin operating the pitman and carried by a drivingshaft having its axis parallel with the axis of the distributer-roll.

2. In an inking apparatus for printingpresses, the combination of inking-rolls, a laterally-movable distributer-roll coo erating therewith, a driving-shaft paralle with the axis of the distributer-roll, and adjustable connections for vibrating the distributer-roll from the driving-shaft comprising an adjustable crank-pin, a pitman, a swinging yoke, and a bell-crank lever, one arm of which is connected by the swinging yoke and pitman to the shaft, and the other arm of which is connected to the distributer-roll.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
