VICTOR FEGLEY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO FABEG MANUFAC- TUBING COMPANY, OF CAMDEN, NEW JERSEY, A CORPORATION OF NEW JERSEY.

INK-DISTBIBUTER FOR PRINTING-PRESSES.

To all whom it may concern:

Be it known that I, Vioron FEGLEY, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Ink-Distributors for Printing-Presses, of which the following is a specification.

My invention relates to certain improvements in printing presses of the type in which a rotary ink distributing disk is used and in which the inking rollers travel over the disk and over the printing form.

The invention is a companion to an application filed by me of even date herewith, Serial No. 825,908, relating to the means for supplying ink to printing presses.

The object of the present invention is to provide means for properly distributing ink as it is supplied, so that, while the ink is fed continuously to the press, it is thoroughly distributed over the disk or ink plate to insure an even impression. This object I attain in the following manner, refrollers; Fig. 7, is a sectional view of one of the small rollers; Fig. 8, is a plan view illustrating a modification of the invention; Fig. 9, is an end view of the modification illustrated in Fig. .8; Figs. and 11, are plan views illustrating other modifications of the invention. Fig. 12, is a sectional view of the ink tube; and Fig. 13, is a view illustrating the supporting rods for the rollers mounted directly in the bearings of the distributing rollers. 7

Referring to the drawings, 1 is the frame of the press.

.2 is the bed.

3 is the platen.

1 is the ink distributing disk arranged at an angle, as shown. I

5 is a pivoted frame carrying the inking rollers which travel overithe ink distributing disk and over the type form secured to Specification of Letters Patent.

Application filed March 19, 1914. Serial No. 825,897.

the bed. This is the ordinary form of job press.

6 is a tube containing ink. This tube has a beveled end 7 and an opening 8, as illustrated in Fig. 12. At the opposite end of the tube is a plunger 9. which is forced for- I ward in the tube by the ratchet mechanism 10, clearly illustrated in Fig. 1. This ratchet mechanism has an operating lever 11 which is moved each time the roller carrying frame 5 makes a movement, so as to feed a given portion of ink from the tube and into the path of the rollers. The tube, in the present instance, is located at one side of the distributing disk t below the center, as illustrated in Fig. 2, so that one end of each of the distributing rollers 12 and 13 take up the ink from the end of the tube and dis tribute it onto the edge of the disk 4.

All ink distributing disks of presses of thistype have a rotary motion and in certain presses, as illustrated in thedrawings, the disk is made in two sections, an inner and an outer section, and one section is rotated in one direction and the other section is rotated in the opposite direction, so that, as the inking rollers travel over the disk, the ink is distributed thereon. If the ink was distributed only on the main distributing rollers 12 and 13, it would takeconsiderable time before it would be evenly distributed over the entire disk and, in order to quickly accomplish this, I provide shortrollers 1% and 15 which are of a sutlicient length to extend considerably on each side of the line of ink taken from the end of the tube 6. These rollers bear against the distributing rollers 12 and 18, as shown. In the present instance, there is a single distributing roller engaged by the arm 16 mounted in the frame 5, andthere are two rollers mounted in a bearing 17 engaged by an arm 18, also mounted in the frame 5. The small rollers 14 bear against the distributing roller 12 and the small rollers 15 bear against the dis tributing rollers 13, as clearly shown in Fig. 3.

I will first describe in detail the rollers 12 and 13 and their supports. The arm 16 has a hooked extension in which the spindle 19 or the roller 12 is mounted and a strap 20 is secured to this hooked eXtension,and mounted between a clamp plate 21 and this strap are the portions 22 of the rods 23 on which the rollers 14 are loosely mounted. The

' of the said rollers.

clamp plate is secured to the strap 20 by screws 24 and the strap is held to the hook portion ofthe rod 16 by the thumb screw a yielding casing 28 of gum or other suitable compound, but, in some instances, the rollers may be made solid without departing from the essential features-of the invention. I

It will be understood, upon referring to Figs. 4 and 6, that the rolls 14, as well as the rolls 15 are free to movelongitudinally on their supporting rods, and in Fig. 6, I have shown collars 29 secured to the rod at such a distance apart as to enable the roller 14 to havea certain amount of longitudinal movement on the rod, as well as to turn freely thereon. This enables the roller 14 to come in contact with the distributing the clamp plate 33 and down on each side roller 12 and also allows it to move longitudinally thereon to more thoroughly distribute the ink taken uprby the said roller. I The rolls 15 are madesimilar to the rolls 14. and are mounted on rods 30 shaped as shown in Figs. 3 and 4. Theends 31 of the rodsare clamped upon the hooked strap 32,

which is secured to'the bearing 17 and to the, clamp plate 33 by screws 34, and the clamp plate is rigidly secured to the bearing 17 by thumb screws 35.

36 is aU-sha ed nlate, which extends over of the bearing 17, so as to hold the parts laterally onto the bearing. The hearing has a I projecting pin 37 with which the hook portion of the arm 18 en ages, so as to trav I erse the bearings and its rollers 13 over the ink distributing'disk and the form. On

' each of the rods 30 are collars 38 and these collars are spaced a greater distance apart thanthe length of the rolls 15, so as to allow'the rolls to have a certain amount of longitudinal movement, the same as the rolls 14. i

It will be seen by this construction that as the distributing rollers travel over the ink distributing disk and over the end of the ink tube 6, a given amount of ink is carried from the ink tube and is distributed over the disk, while the same rolls, which come in contact with the ink distributing rollers, are in line with the tube and distribute the ink taken up by these rollers over a certain area and, as they are free to move longitudinally as well as to rotate, they quickly distribute the ink so that by the time the disk has made one revolution the ink is thoroughly distributed over said disk. The construction illustrated in Figs. 3 and 4 can be applied to any printing press of the typeillustrated, as the strap 32 can be hooked onto the bearing 17 and the clamp plate 32" can be attached by a clamp screw 39 and the strap 20 can be slipped onto the head of the arm 16 and clamped thereto.

In Fig. 13, I'have illustrated the bearing 17 having openings for the portions 31 of the rods 30 carrying the rolls 15 and these rods are held in the position to which they are adjusted by nuts, as illustrated, dispensing with the strap and the clamp plate.

In Figs. 8 and 9, I have illustrated a modification of the distributing mechanism, in which the rolls 14 and 15 are mounted on arms pivoted at 40 to a clamp 32*. Each pair of rolls bears upon a distributing roller by a spring 41, but if it is desired to throw the rolls out of action they are simply turned up on their pivots, as illustrated by dotted lines, Fig. 9; the springs holding them out of action. I

It is the usual practice to have a single tube and a series of supplemental rolls at one end of the distributing rollers in line with the tube, but, in some instances, the supplemental rolls may be duplicated at the opposite end of the distributing rollers, which quickens the distribution of theink, and, in some instances, a tube may be located at each side of the press and the supplemental rolls may be located in line with each tube, as shown in Fig. 10.

In Fig. 11, I have shown the supplemental rolls 14? extending the full length of the rollers 12, and these rolls have a longitudinal motion, as well as a rolling motion against the rollers 12, increasingthe effectiveness of the distribution, although, in ordinary practice, the long rolls are unnecessary for the proper distribution of the ink.

It will be seen, in all of the modifications, that the essential feature of the invention is the thorough mixing or the thorough distribution of the ink on the ink disk, so that, when the type form is supplied with ink, the ink will be evenly distributed over the type form.

It will be noticed, upon referring to Figs. 4 and 5, that the rods 23 and 30 are arranged at an angle with respect to the axis of the rollers 12 and 13. This insures the longitudinal vmovement of the rolls upon their rods so as to distribute the ink over a portion of the surface of the rollers.
