MULTICOLOR INKING APPARATUS.

Specification of Letters Patent.

Patented Apr. 30v, 191%.

Application filed April 16, 1917. Serial No. 162,297.

To all whom it may concern Be it known that I, ELMER NICHOSON, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Multicolor Inking Ap paratus, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to multi-color inking apparatus, more especially designed for Gordon presses.

The functions and advantages of the in vention can bemore easily understoodand explained when the particular mechanism that I use to carry out the same is understood. The usual general introductory statements are, therefore, omitted.

In the drawings,

Figure 1 is a side elevation of a Gordon press equipped with the multi-color inking apparatus. i

Fig. 2 is a front elevation of the inking apparatus dissociated from the press.

Fig. 3 is a rear elevation of the inking apparatus.

Fig. 3 is a cross section of the inking apparatus and the inking table.

Fig. 4 is a plan View of the inking table.

Fig. 5 is a perspective of one of the inking strips adjustably securable upon the table.

Fig. 6 is a perspective of one of the inking fountains.

Fig. 7 is a longitudinal section of one of the distributer sections and the shaft upon which it is mounted.-

Fig. 8 is a cross-section on the line AA of Fig. 7.

Fig. 9 is an end view of one of the lock washers.

Fig. 10 is a cross section on the line 3-13 of Fig. 7. V

Fig. 11 isa detail of the band about the two-part jam-nut shown in the preceding figure.

Fig. 12 is a detail of the fountain frame and coil spring connection with the heel.

The Gordon press is shown in Fig. 1 and needs no explanation. In place of the usual rotary inking table used on a Gordon, a speclal table a is employed, rectangular in plan and provided with graduations at the top and bottom by which the spring strips 6 may be definitely and accurately located upon the table. The spring strips are sprung over the table so that they hold themselves in any position where they are left.

The usual form rolls 9 that travel over the table and over the form are mounted upon a saddle which can draw in and out against spring pressure afforded by a spring (not shown) in the carrier 0. The top end of the table is curved inward (see Fig. 3 This secures a very useful advantage in not drawing the form rolls so far out of the carrier as toput the spring under unnecessary tension and easily wear out the composition form rolls 9, and it serves to considerably lower the multi-color inking apparatus so as to make it very much more convenient for the operator.

A pair of uprights 0Z, d, carry the composition rolls 6, e, and also pivot the arms 7, f, at whose upper end are journaled the threaded distributor roll shafts g, 9, along which are the adjustable distributing units it. These distributing units are detailed in Figs. 7 to 11 inclusive and comprise the twopart metal distributing rollerz' provided at on the shaft. The two parts of the j am-nuts are held together by bands 10. This halving arrangement of the rollers and nuts allows them to be assembled on or adjusted along the shaft without sliding or turning them. To get an accurate adjustment of the distributing units relative to the inking strips, these distributing rollers may be dropped down upon the inking table as shown in the dotted lines of Fig. 1 by releasing the catch m. This allows both the inking strips and the distributing units to be accurately placed, and is a valuable feature. The stress with which the metal distributing rollers bear against the soft composition rolls may be regulated by turning the screw a (Fig. 2) which is provided with a nut 0 by which the catch'm is attached. One of these adjusting devices is provided on each side of the press.

At the rear of the multi-color inking apparatus is shown (Fig. 3) the fountains; for instance, the long upper fountain g is provided and the two lower short fountains are afforded. Of course the length might be diflerent and the number variant. These fountains are supported by means of a hooked :bolt 8 which hooks under the supporting rod t, and when the nut to is screwed down it supports the rear of the fountain. The front of the fountain is supported in adjustable relation with respect to the fountain roller 12, by means of a thumb screw to, whose lower end bears on the cross bar 92.

Referring to Fig. 1, the link g, which connects the movable half of the Gordon press with the stationary half, is arranged to strike the heel e on the lower end of the upright d and put under tension the spring 11 which connects the fountain frame and fountain rollers, .(Fig. 12.). The frame is locked from following the heel 2 by the catch 12 (Fig. 1). The latch 13 on the end of the link y passes under the trip arm 2 inactively but on the return the latch strikes .the trip arm 2 and through suitable linkage shifts the pawls 3 and rotates the fountain rollers so as to distribute the ink over the composition rollers. Coincidently with the rotation of the fountain rolls the linka 'e 14 carrying the pawls releases the latch 12 and allows the spring 11 to thrust the fountain rolls against the composition rolls. 1, 1 designate a pair of stops which engage under the rod 5 (Fig. 2) to prevent the fountain frame from tipping back beyond a given point when contact between the heel and the end of the link y ceases.

The composition rollers e, e, are not only driven in rotation by the pulley 6 but they are caused to reciprocate longitudinally by the interconnecting and flan ed obliquely-set pinion 7.

From the above description it is apparent that two lines of inking fountains are provided, and two lines of distributing rollers, the elements in the latter being staggered. This arrangement permits several lines of color to be drawn from one fountain as shown in connection .with the upper fountain in the drawings. The lines of the ink can also be run closer than under the arrangements in prior use. Further, by the use of a full length fountain, one color of ink can be run the entire width of the paper without detaching and replacing the fountains. Further, one color can be run alone clear across the form on a Gordon press without requiring any further change than the removal of some of'the distributing rolls.

The above arrangement .of fountain rolls,

race rec composition rolls, di tributing J'ulls and form rolls serves as a very convenient distributor of the ink over the inking table, which is not possible with the rotary table style of inking devices ordinarily in use on Gordon presses. Thiseven distribution is greatly facilitated by the recijn'ocating movement of the composition rolls. This enables production of such kind of work, as half-tones, which cannot ordinarily be done on the Gordon press when using the automatic ink-feeder.

That I claim is:

1. In multi-color inking apparatus, the combination of a table provided with inking sections and one or more lines of distributing roll sections normally removed from the inking sections but which can be swung down over the inking table to make accurate adjustments.

2. In multi-color inking apparatus, the combination of an inking table provided with a plurality of inking sections adjustable along the table, and one or more lines of distributing roll sections which are normally removed from the inking sections but which are adjustable longitudinally and can be swung down upon the inking table to secure accurate adjustment.

3. In multi-color inking apparatus, the

combination of an inking table provided with a plurality of adjustable inking strips, a gage on the inking table, and one or more lines of distributing roll "sections which. are normally removable but which are adjustable longitudinally and which may be swung down upon the table to secure the coopera tion of the gage to properly adjust the same.

l. In multi-color inking apparatus, the

combination of a iair of composition rolls,

uprights for ournaling the same, an inking table provided with adjustable inking sections, a pair of lines of distributing roll sections adjustable longitudinally, a pair of arms journaling said distributing roll sections and pivoted to the uprights, and a catch for holdin the said distributing roll sections against the composition rolls but allowing them to be swung down upon the table for the aurpose of adjustment.

5. In multi-color inking apparatus, the

combination of one or more composition rolls, uprights for j ournaling the same, one or more lines of distributing rolls, arms for j ournaling the same which are pivoted to the uprights, a link or catch for holding the rolls against the composition rolls, and a screw and nut connecting with the opposite end of the link or catch for adjusting the stress of the distributing rolls against the i composition roll or rolls.

6. In multi-color inking apparatus, the combination of an inking table, and a plurality of adjustable strips, comprising strips of metal whose ends are curved in .to hook over the edges of the table and which are sprung in place so as to hold themselves in the various positions of adjustment.

7. In multi-color inking apparatus; a dis tributing roll unit, including a distributing roll sleeved on a threaded shaft, halved 3' am nuts threaded on the shaft, and a band for holding the same together.

8. In multi-color inking apparatus, the combination of composition rolls, a fountain frame, fountain rolls thereon, a heel rockingly supported, a spring connection between the heel and frame, a latch for keeping the frame and fountain rolls away from I the composition rolls although the heel is tripped and the spring put under tension, and means for contemporaneously unlatching the said frame and giving the fountain rolls movement.

In testimony whereof, I sign this specification.
