IMPROVEMENT IN INKING APPARATUS.

Specification forming part of Letters Patent No. 142,457, dated September 2, 1873; application filed December 26, 1871.

To all whom it may concern:

Be it known that I, GEORGE P. GORDON, of Rahway, Union county, New Jersey, have invented, made, and applied to use, certain Improvements in the Construction of Printing- Presses; and that the following is a full, clear, and correct description of the same, reference being had to the accompanying drawings making part of this specification, and to the letters of reference marked thereon, in which- Figure 1 is a longitudinal sectional view of my invention, the rollers receiving the ink fromthe ink-table. Fig. 2 is a longitudinal sectional view of my invention, the bed having reached the extent of its throw and the rollers having been advanced.

In the drawings like parts of the invention are pointed out by the same letters of reference; r

The nature of the present invention consists in certain improvements, as more fully hereinafter set forth, in the construction of printjug-presses; the object of the invention being, by combining with the bed of a printingpress moving in one direction a roller-carriage moving in the opposite direction, to ink the form carried upon the bed with a greater number of rollers than if the rollers were stationary, as is usual, and to shorten the distance traversed by the bed in order that the form may be properly supplied with ink, thus enabling a greater amount of work to be done upon the machine, if run at the same rate of speed at which the usual machine is run.

To enable those skilled in the art to make and use my invention, I will describe the same.

A shows the frame of my printing-machine, constructed in the usual manner, and made sufficiently strong to support the operative parts of the press. B shows the grooved ways in which the bed U of the press moves to and fro, this motion being imparted to the bed througha crank upon the shaft E, connected to the under side of the bed 0 by means of alever and link. Upon one end of the shaft E is secured a cog-wheel, F, gearing into a pinion. Upon one side of the top of the bed is secured a rack, G, gearinginto a segmental pinion,H, secured upon the shaft 1, supporting the impression-cylinderJ, used,in connection with the "from the feed-table of the press.

bed 0, to produce an impression. This cylinder has its impression portion formed of a segment of a cylinder-built out upon the cylinder proper, and is provided with a set of sheettaking nip pers to receive and carry the sheet to be printed Upon the end of the cylinder-shaft is secured a partiallytoothed wheel, K, which engages at the proper moment with the cog-wheel F and completes the revolution of the cylinder. the cylinder having been driven or operated so that after the nippers take the sheet from the feedtable the same shall be properly presented to w the type, an impression taken, and the sheet delivered to a series of tapes and fly, or some proper means, to pile it, by the joint action of the segmental gear H engaging with the rack upon the bed and the partially-toothed wheel K engaging with the cog-wheel F. The seg-v mental cylinder at its rear is cut away sufficiently to allow the ink-roller carriage M to be advanced a certain distance beyond the faceline of the bed 0. M shows a roller-carriage,

in which are placed the inking-rollers N, em-

ployed to ink the types. This roller-carriage is composed of the end and side pieces fastened together so as to form a frame in which the rollers may be easily placed, and from which they may be removed at pleasure. The end pieces in the present instance are grooved so as to form ways in which are received lugs or projections, not shown, secured upon the frame of the press. These lugs, fitting as they do into the end pieces of the roller-frame, serve in a measure to guidethe rollers and hold them to their work.

The rollerframe or carriage has secured to its rear end the curved links P, the opposite ends of which areattached to the curved levers Q hung upon a rock-shaft, R, passed through the lower portion of the frame A.

To this rock-shaftR is attached a connection,

S, in the opposite end of which is secured an arm and roller, the roller playing in a cam, U, secured upon the same shaft as the cogwheel F.

The inking apparatus consists, in the present instance, of a revolving ink-distributing table, V, secured at the rear of the bed and moving with the same, a section or part fountain, \V, secured upon a back F915; or sup Enron.

port on the main frame, to which is also attached a distributing-roller, X, intended to take ink from the fountain W and supply the sameupon one side of the table V, and also employed to assist in breaking up or distributing the ink supplied to the table V.

As heretofore stated, the nature of my invention is to combine with the bed of a printing-press moving in one direction aroller-ca-rriage moving in an opposite direction, and the object is to shorten the throw of the bed, and to ink the form with a greater number of rollers than it the press were constructed in the usual manner. Heretofore the rollers employed to ink the form, more particularly in cylinder-presses, have been held in stationary supports placed at or near the front end of the press, and the result has been that to ink the form the bed has been thrown or carried beneath these rollers, thus giving a long throw, so to speak, to the bed.

In the present instance, by making the rollercarriage movable, and causing one or two rollers, as may be deemed best, to be advanced beyond or in front of the form, after the bed has reached the terminus of its throw-back, the bed is not compelled to travel so great a distance as formerly, and the result, as already stated, is that, should the machine, constructed as just described, be run at the same rate of speed a greater number of impressions can be obtained, as the bed travels a less distance than formerly; and if it be deemed advisable to drive the new machine so as to ink with the same number of rollers as formerly, the bed is moved more slowly, and friction and wear of the working parts are decreased.

The operation of the roller-carriage and the bed of the machine simultaneously and in opposite directions is briefly as follows: Motion being imparted to the driving-shaft E the cam U, through the arm S, rocks the shaft It, which vibrates the levers Q, reciprocating the rollercarriage attached to their upper ends. The cog-wheel F being similarly rotated gives motion to the bed through the partially-geared wheel K, and as the cam revolves in unison with it the movement of the roller-carriage is governed, as to time, with the movement of the bed, the cam being so shaped or formed as to give a forward movement to the rollercarriage as the bed accomplishes its backward movement, and in this way causing the rollercarriage to move simultaneously with and in opposite directions to the bed. The roller playing in the cam is governed by the same, and carries with it the connection, so that the shaft R is rocked forward, carrying with it the curved uprights attached to the rollercarriage by link P.

It will be easily seen that the cam may be so shaped as to give any necessary forward movement to the roller-carriage, so that one, two, or even three rollers may be advanced beyond the face line of the bed, if desired.

Having now set forth my invention, what I claim as new, and desire to secure by Letters Patent, is-

In combination with the bed and rollercarria-ge M, constructed and arranged to operate as described, the segmental cylinder J, having a portion of its surface cut away, as and for the purpose set forth.
