Specification of Letters Patent.

Patented. July 2, 1912.

Application filed May 24, 1909. Serial No. 497,828.

To all whom 'it may concern: I

Be it known that I, HENRY C. ()snonN, a

"citizen of the United States, residing at- Cleveland, in the county of Guya-hoga and State of Ohio, haveinvented' a certain new [and useful. Improvement in Inking Rollers,

of \vhichthe following is a full, clear, and

".enaotdescription,reference being had to the accompanying drawings.

' 'l he objectfof this inventionis'to provide a very simple" and efficient inking roller which is formed to Workup and distribute thezink, thus doing away with the necessity of an additional longitudinally moving distributing roll. My inking roller is. adapted to: have" the: ink applied directly to it, wherey by it also takes the placeof an inkingfountain or disk.

My inking roller is well adapted to cooperate with a small; ofiice printing press, for-example of the type of the multigraph or .gannneter printer. The iuvention'is illustrated herein as applied 'to such construc: tion, and its essential characteristics will be clear frointlic following explanation of-such illustration and from theappended claims.

In the drawings, Figure 1 is a plan of a portion of a rotary printing drum with my inking roller and an intermediate transferring roller coiiperating therewithyFig. 2 is" an end view of. such parts; Fig. 3 is a 1011- itudinalsection through my inking roller; ".lilgs. 4: and 5 are transversesections of the same on the correspomlingly numberedlines Of Fig. 3.,

My: inking roller, as shown, consists essentiall of" a body portion A, in the form of a 'mutilated cylinder, and one or more segments B B, which are set into recesses in the surface oft-he member A,the outer surface of the member and segments comprising a circular roller, as appears from Figs. 4 and 5.

In the embodiment shown, the body A of the roller-is provided at'its ends with bushings C and C, by which it is journaled rolatably on the rod or shaft 1). This shaftis shown as mounted in. the brackets E and E3, which are secured to the frame plates Fund F of theprinting machine. On the shaft, near its center is provided a double crown cam Gr which is made by agroove inxa sleeveheld. against rotation on the shaft. The segmental members BB, of which two are shown, have inwardly extending arms I),

The result of the above construction isthat if'the roller be rotated relatively to the shaft the partially cylindrical members-B B will be automatically moved, one in one direction, and one in the other to continually distribute the ink. Suitable space, as a,'in the body A allows for such movement ofthe inwardly extending arms I).

To cause a relatively slow travel-of the rollers H in the groove 9, while the inking roller itself is rotating at a greater speed, I rotate the shaft D in the same direction as the roller A, but at a different'speed. This differential ma be varied according to circumstance's and operates to radually move the segmental members B bac ward and forward during the continuous rotations of the inking roller.

The gearing shown for causiligtlle differential rotation of the inking roller and shaft is very simple and comprises a gear K on the roller meshing with a. gear L 011 the intermediate roller N, which latter meshes with the gear P on the drum R of the printing machine, while rigid on the shaft n of the roller N is a gear J meshing with the gear I on the shaft D. The gears J and I have a dilferent speed ratio from the gears L and K; A set screw S is shown as screwing into the bracket E and occupying a groove. (2 in theshaft, preventing its longitudinal shifting while allowing its rotation.

The drum R, as shown'in Fig. 2, may be formed with rails to carry parallel lines of individual grooved type, after the manner of .the multigraph. When the drum is rotated,

such type come 1n contact with rotating roller N, made of composition, and receive ink therefrom, the roller N being continuously and evenly inked from my fountain roller described. The ink is supplied in a paste form by an ink knife or otherwise to my fountain roller and isworked up by the shifting of the members B and B thereof.

My fountain roller may be. very easily taken apart for cleaning and reinstalled. The loosening of the screw S allows the shaft D to be drawn out of the brackets E E. This allows the removalof the roller as a xwhole. It also frees the segmental members and the sleeve G. Tozreinstall the parts, the

sleeve G is placed in the recess a in the body Aand the members B are ut in place with the rollers H occupying t e groove 9. In this position, the eyes through the arms b aline. The shaft is then projected length- I wise through the bearin E, the bushing C,

the first set of arms b,-t e sleeve G, the second set of arms I), the bushing O and the bracket E.

In order to hold the sleeve G stationary with reference to the shaft, it is provided with a key g" (Fig. 4) which is adapted to occupy a key-way d extending along the shaft, from a point at the headside of the '15 sleeve to the free end ofthe shaft. Accordingly, after, the shaft has been passed through theeyes of the first arms 6 and abuts the end of the key y, it is simpl turned axially until its key-way alines with the key when the shaft is shoved home and locked'by the screws S. The composition roller N which forms the intermediate member between my fountain roller and the type is shown as having axial studs n, which are v mounted'in eccentric bushings T carried in the corresponding brackets E E. These bushings have heads adapted to receive a wrench for their adjustment and they are locked by suitable screws as U. It will be seen from the above description that my invention is extremely simple in construction and greatly reduces the number of parts required for an inking attachment. Moreover, it is very easily applied and removed and may be taken apart for cleaning whenever desired.

Having thus described my invention, what I claim 1s:

1. The combination of a rotary printing 40 drum, an ink conveying roller cotiperating therewith, and a fountain roller in contact with the conveyer roller and having a por- Lion of its surface movable with reference 'to another portion, and means for longitudi nally reciprocating such portions whereby such mutually moving portions overlap each other longitudinally.

' 2. In an inking roller, the combination of a plurality of segmental surfaces of the same radius which cooperate to make a roller, means for rotating said surfaces as a unit, means for moving one of the surfaces with reference to the other during a rotation.

3. The combination of a shaft, a cam thereon, a'roller rotatably mounted on the shaft, a shiftable member on the roller, havmg its exterior flush with the exterior of the roller, and a connection between said member and said cam. v

4. The'combination with a shaft, a mutilated roller mounted thereon, a segment of a Copies of this patent may be obtained for roller mounted in a recess in the mutilated roller to have its exterior flush therewlth, a cam, and a connection between the same and the segment, whereby the segment 1s longitudinally shifted as the composite rol er rotates.

5. The combination of a mutilated roller having an arc-shaped recess 0n its surface, an are shaped plate mounted in said recess and having its exterior .surface flush with the surface of the roller and having an inwardly projecting member, a cam, and a groove in the cam which said member occupies.

6. The combination in an inking roller, of

a body portion having a partially cylindrical exterior, of-a pair of recesses between the cylindrical portions and exterlorly flush with the roller surface, a pair of longitudinally movable segments mounted 1n said re-' cesses, and means for. shifting said segments in opposite directions as the roller rotates,

- 7. The combination in an inking roller, of a body'portion having a partially cylmdrical exterior, of a pair of recesses between the cylindrical portions, a pair of longitudinally movable segments mounted in said recesses and exteriorly flush-with the roller surface, arms on said segments extending into recesses in the roller, and a supp'orting shaft passing through eyes in said arms.

8. The combination with a printin member, of a rotatable inking roller t erefor having two portions of its surfaces in the form of longitudinally shiftable segments separated by non-shiftable portions of the roller, and means for shifting said segments in opposite directions as the roller rotates.

9.. In an inking attachment for rotary printing presses, the combination of a pair of brackets, a shaft adapted to be mounted therein, a fountain roller and a transferring roller mounted in saidbrav-kets, said fountain roller being composite with one portion of its surface shiftable with reference to another "portion, and means'for moving such shiftable portions longitudinally with reference to each other.

10. The combination of a-- roller made i of a plurality of relatively movable inking In testimony whereof, {hereunto affix my signature in the presence of two witnesses.
