Letters .Pa-tent No. 102,157, dated April 19, 18701 The Schedule referred to in these Letters Patent and making part pf the same I, ISRAEL L. G. RICE, of Cambridge, in the county of Middlesex and State of Massachusetts, have in-v Nature and Object of the Invention.

My invention consists in furnishing a means by which printing-inks of various colors may be steadily fed to inking or distributiug-rollers upon printingpresses, so that several colors may be printed at one impressiop.

rIhe invention is designed particularly to be used with the "inking-apparatus for which a patent was granted to nie, bearing date ot" April 20, 186th Description of the Accompanying Drawings.

General Description.

The receptacle or fountain for the ink is made as follows:

A A form two sides, B the front, the roller C the bottom, and the clamp D the back.

The ink is put in at the top, shown at E, and remains in the space inclosed by A A, B, C, and D.

The roller C is held in position by two rings, one on each side, which are fastened to the sides A A, as shown at H, and which are placed in the grooves out in the roller. These rings serve as guides or bearers tothe roller G.

To regulate the quant-ity of ink to be supplied to the inking or distributing-rollers, I bend the piece B, which is soldered to the two sides A A, round, so that it almost touches the roller C. I then put a screw, J, through the block I, which is between the two sides A A, and turn the screw so that it presses B as near C as may be required.

rIhrough the top of the clamp D, I put` a screw, K, so that the fountain may be fastened to the bar M.

The two uprights L L and the bar M form aframe, on which the ink-fountains are' to be placed. L L also form bearings for the shaft N On the shaftNat one end, I place a collar. I also out a groove, so that, as the shaft N revolves, G turns with .it, there being a pin in the roller C fitting in this groove.

To use these fountains, I proceed as follows:

I bolt the two uprights L L-upon the press, in position so that the distributi11g-rollers may come in Contact with the rollers C. I then fill. my fountains with ink. l use fountains to correspond with the distributin'g-disks used in the inkingfapparatus aforesaid. lhes'e fountains are secured in their `relative positions by the screw II. The shaft N is then put through the holes in the center of the roller C. The shaft N is then put in motion by means of a ratchet;` wheel and lever, which is moved by the carriagef'of the inkingapparatus referred to above, strikingagainst it-,or by a belt, or by any other suitable means, according to the press upon which it is used. As the rollers C turn, the ink adheresl to them, and is carried to the inking or distributirig-rollers as they come in contact with it.

Claims.

vl claim as my invention- 1. A fountain made with a clamp, D, and having a roller with a key, s0 that the fountain may be readily adjusted to any position on the bar M and shaft N, substantially as and for the purpose set forth.

2. The bar M and shaft N, when used in combina* tion with the fountains described above, substantially as, iu thc manner, and for the purposes set forth.
