Description

G. K. FARRENGTON & B. S. POTTER.
inking Apparatus for Printing-Presses.
No. 132,000. Patented Oct-8,1872.
UNITED STATES EEIO PATENT GEORGE K. FARRINGTON AND BRADFORD s. POTTER, OF BLOOMINGTON,
ILLINOIS. I
Specification forming part of Letters Patent No. l2.,000, dated October 8, 1872.
: of which the following is a specification:
Our invention consists of an ink-fountain and feed-roller, combined with a distributingdisk having a beveled margin of the upper surface, on which disk the said feed roller works in a manner calculated to effect a more equal distribution of the ink than can be had with the ordinary fountains. The fountain proper is fixed in connection with the feedwheel detachably, so that interchangeable fountains, containing differentcolored inks, may be'used.
Figure 1 is a sectional elevation of a dis tributing-disk, and end elevation of the fountain; Fig. 2 is aplan view; and Fig. 3 is a section of Fig. 2 on the line 00 w.
Similar letters of reference indicate correspondin g parts.
A is the distributing-disk of a Gordon or other press, which we propose to bevel on the margin of the upper surface, as shown at B. (l is the ink-feeding roller mounted in one end of the box-like frame D, which is swiveled at E on a support, F, so that said wheel may swing on or OK the bevel to run wholly or only partly on it. The said support F is so beveled that the surface of the roller will run flat on the bevel. The support F may be made adjustable, so that the feeding-roller may be also adjusted to the plane of the disk, and, by compression of the feed-roller upon the disk, it can be made to run partly upon the plane and partly upon the beveled surface, to suit the nature of the work.- G is an ink-fountain or to entirely shut off the ink from feed-roller be fore removing it fromthe frame;
This fountain being arranged with the distributing-disk, as shown, either to deliver a narrow strip on the outer edge of the bevel, or a strip as wide as the face of the wheel upon the bevel, or upon the plane lsurface, or partly on bevel and plane. The ink so distributed is taken up and further distributed by the distributing-rollers of the press. The said distributing-rollers, passing over the disk, take a portion of the ink from the plane at each side of said disk, and when the beveled edge comes on aline parallel with the surface of the distributing-roller, the latter passes wholly over the beveled surface. This gives an equal distribution over the whole surface of the disk. By the adjustment of the box G, by means of the adjusting-screw K, toward or from the feed-roller, a thick or thin layer may be supplied, as preferred.
The arrangement of the ink-holder G, for taking out and putting in readily, allows of changing from ink of one color to another by having several holders, G, supplied with inks of different qualities and colors. By delivering the ink on the beveled margin only the distribution on the disk will-be greatest at the center, and, by moving the feed-wheel inward, so that it will deliver wholly upon the plane surface inside of the bevel, the distribution will be morev on one side of the disk, so that we may regulate the said distribution according to the nature of the work in hand with great exactness.
The advantages due to the beveled margin of the distributing-disk are alike available with any feeder that can be adjusted relatively thereto, as hereinbefore described.
Having thus described our invention, we
claim as new and desire to secure by Letters Patent- 1. An ink-distributing disk for printingpresses, having a beveled margin, and combined with an adjustable feeder, which can be adjusted to the bevel or plane of the disk, or partly on the bevel and partlyon the plane at the same time, substantially as specified.
2. The combination, with the feed-roller O, of a detachable and adjustable ink-holder, G, substantially as specified.
