JOHN MOADAMS, OF BROOKLYN, NEV YORK.

LINE-PRINTINIG MACHINE;

SPECIFICATION forming part of Letters Patent No. 403,206, dated May 14, 1889.

Application filed September 20, 1887. Serial No. 250,170. (No model.)

T0 aZZB whom it may concern:

Be it known that I, JOHN MCADAMS, of Brooklyn, in the county of Kings and State of New York7 have invented a new and useful Improvement in Line-Printing Machines, of which the following is a specification.

I will describe in detail a line-printing machine embodying my improvement, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a side view of the portion of a machine embodying my invention which includes theV printing and supporting rollers and also the inking mechanism. Fig. 2 is a plan of the parts shown in Fig. l. Fig. 3 is a plan of a portion of an ink-fountain made according to my invention; and Fig. 4 is a transverse section thereof upon about the plane of .the line x x, Fig. 3. Fig. 5 is a section lengthwise of the machine of the parts shown in Fig. 1. Fig. 6 is a section, lengthwise of the machine, of an arrangement of tapes or cords and brushes whereby the paper may be cleaned as it passes to the line-printing rollers; and Fig. 7 illustrates another `arrangement of tapes and cords, including a beater and an air-blast apparatus, whereby the paper may be similarly cleaned..

Similar letters of reference designate corresponding parts in all the figures.

A designates the main frame of the machine, and B B' designate the pairs of line printing and supporting rollers by which the lines are printed upon opposite sides of the sheet.

O designates the feeding-apron or cords, which pass over suitable snpporting-rollers, O' C2, and by which sheets of paper are fed from the feeding end of the machine to the printing or ruling apparatus; and C3 designates a portion of the delivery apron or cords 011 which the paper is delivered from the machine. i

In Fig. 6, which represents the feeding end of the machine, I have shown brush-rollers or dusting-rollers D D', and two systems of endlesscords or tapes, co b, which pass around and are suitably directed by rollers a' a2 a3 w* bf, 222 b3 b4, so as to carry the paper in contact with the brushing or dusting rollers D D', as represented by the arrows 'in Fig. 6. The dusting roller or brush D has extending below it a suitable shield, 115, which prevents the dust and scraps from falling on the paper as it is fed along by the apron or cords O. The paper is by hand fed to the cylinder or roller a' and the tapes or cords a, and is carried around in the direction indicated by the arrows, and by which one side is presented to the action of the brush D, and then passes on the roller or tapes and cords b' b, by which its other side is presented to the action of the brush D'. From the tapes or cords b the sheet is delivered to the apron or cords O, and is by them carried forward in the direction indicated by the arrows in Fig. 6, to the apparatus for printing or ruling the lines thereon. p

In Fig. 7 I have shown a dusting apparatus of another form which embodies my invention. In this apparatns the paper is fed between two series of cords or tapes, D2 D3,which are carried and moved by rollers D4 in the directions indicated by the arrows. Below the upper paper-carrying portions of the tapes or cords D3 is a roller or beater, D5, of polygunder surface of the paper and fall into thev dust-pan D7.

To clean the upper surface of the paper, I employ a blast of air7 which may be supplied from a blower, as shown, through a pipe, D6. The paper passes from the feeding apron or tapes C directly between the cylinders or rollers B B' of the first pair and B' B of the second pair7 and is delivered onto the apron or cords O3, which convey it from the machine. In passing between the first pair of rollers B B' the upper surface of the paper is printed by the roller B, and in passing between the rollers 'of the second pair its lower surface is printed with lines by the roller B. Each of the four rollers B B' has a series of disks, c, the edges of which are presented in a straight line from end to end of the roller, and which are set at a distance apart equal to the desired distance between the lines. The disks of the rollers of each pair are so placed that the disks of. the roller B, for example, come between the disks of the roller B', and consequently IOO when the paper is passed between these two rollers the natural clasticity of the paper holds it against the edges of the ln'intingdisks c.

The four rollers B B ll' are intended to be intcrchangeable, so that they maybe used in any arrang'ement or combination, and the dislcs of the several rollers may be set at various distances apart to produce lines on the paper at any desired distance apart.

In order to provide for readily changing` the rollers B l', so as to form different combinations of them, their journals d are supported in slotted bearings d' in the frame A, as best shown in Fig. 1,and they are provided at opposite ends with friction-wheels e, which bear one on another. The frictio11\\'l1eels e of the lower rollers of the two pairs bear upon corresponding` friction-wheels, E2, which are upon a shaft-,E, extending across the machine beneath the aforesaid rollers, and to which motion may be imparted by a driving-belt passing` over a pulley, E'.

The friction-wheels c, which are upon opposite ends of the rollers B l', are of such diameter that when the wheels at opposite ends of the upper and lower rollers of each pair are in contact the edges of the disks c of one roller will be in proper relation to those of the other roller to pcrform the printing` operation, and by the frictional contact of the Wheels E2 e the rollers of each pair are driven from the shaft E. It will therefore be seen that when the rollers are placed in any combination their frietion-wheels e will be in contact with each other, and the wheels c upon the lower rollers will be in contact with the frictional driving'-wl1eels E2.

F F designate the ink or color fountains, from which the upper roller B of the first pair and the lower roller B of the second pair are supplied with ink or color.

G G dcsignate the two color-rollers, which rotate in the fountains, and the j ournals of which are supported in slotted bearingsf and by antifriction Wheels I have also represented other ink or color wheels 01' rollers, G', which rotate in contact with the lower roller 3' of the first pair and the upper roller B' of the second pair. These inking 01' color wheels or rollers G' are supplied with color by suitable feeders, g, from fountains G2, secured upon the frame of the machine. The ink or color rollers G' may be arrang'ed to ink or color certain of the disks of the supporting-rollers I', so as to produce on the paper head 01' other lines in a different color, as is indieated by the arrangement of the rollers G' in Fig. 9.

Instead of employing a separate fountain for the ink or color rollers G', which are arranged to supply ink or color to only one or two of the dis'ks which are on those rollers which serve as supporting-rollers I', I may form a divided fountain, such as I have represented in Fig's. 3 and i. In those fig'ures F designates the main portion of the fountain, wherein the color-rollers G are intended to turn, and the :fountain is constrncted with transverse partitions 71, 71/ W, thcreby forming,` compartments F' F2. The fountain also has beyond the partitions h' 71,2 a supply box or compartment, F3, which is in full communication with the compartment F' by a bridge or covered passagc, 71,3, extending through the compartment F2. The portion FAl of the compartment is in free communication with the main portion F by means of the bridge or eovered passage hi, which extends across' the compartment F', and color which is supplied to the main portion F and compartment Fl overtlows across the bridge h* and fills the compartment F2.

From the above description it will bc understood that the same color or ink will till the compartments or portions F F2 F4, while a different color or tint may be used in the compartments F' F3, which are in free communication by the bridge or covered passage W. By means of this divided fountain color wheels or rollers may be arranged to supply one or more of the printing-disks at the end. of the printing-rollers with ink of a different color or tint from that supplied to the main portion of the ink-fountain and delivered by the roller G along` the length of the printing'- roller.

In Fig. 2 I have 4 represented the upper printing-roller B as having' at its end an arrangement of printing-disks, c, whereby it operates, in connection with the disks at the end of the upper supporting-roller B' to produce head-lines, and the color'roller G, for supplying the upper printing-roller I', has color-disks G'` G3, which run in and take color from the compartments F' F2 of a colorfountain like that shown in Figs. 3 and i. In order to render the ink-fountains F and the ink-rollers G self-adjusting relatively to the printing-rollers B B, I have :represented them as supported upon inclined seats 01' rests a upon the frame. They will then have a tendency to gravitate downward, which will carry them in a direction to cause the rollers G to come into contact with the disks or printing' or pen rollers and to maintain them in such working-contact. I thus dispense with any means of fastening` the ink-fountains in place, and enable them and their rollers G to readily adjust themsclves in proper position relatively to the printing-rollers.

For each inking-roller G, I employa wiper, II, which may be made of india-rubber, and which is approximately tangential to the roller. This wiper serves to remove from the roller the surplus of ink. It is held in a Suitable holder, II', which is free to slide toward and from the roller G, and to which are con? i bc employed for adjusting the holder II' toward the roller G, while the screws and. nuts IOO ITO

fi i' may serve to withdraw the wiper from the roller.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination, in a line-printing' machine, of pairs of rollers, those of each pair being' arrang'ed one above another and all provided with disks. c, and which are interchang'eably fitted in the machine, so that eitherv of each pair may serVe as a printing'- roller and its Companion as a supportingroller, and of inking` apparatus for supplying color to the disks of the printing-rollers, substantially as herein described.

2.' The combination, with pairs of line-printing' and supporting` rollers arranged side by side and those of each pair one above another, of friction-Wheels applied to their j ournals and bearing` one on another, and a drivingshaft having` friction-Wheels in contact with those upon the lower rollers of the pairs, whereby the rollers are driven and held out of contact and at the proper distance apart for printing, snbstantially as herein described.

8. The combination, with the printing-rollers and their opposite supporting-rollers, all supplied with disks c, of ink fountains and rollers for supplying color to the disks of the printing-rollers, and separate ink fountains and Wheels or ink-rollers for supplying' color to certain of the disks of the supporting-rollers, snbstantially as herein described.
