IN'KING ROLLER.

yppucwmm mea August '6, 1924. serial No. 730,419.

To all 'whom t may concerm v Be it known that JAMES F2 PERKINS, a citizen of the United States, residing at Hayward, in the county of Alameda and State of California, has invented certain new and useful Improvements in Inking Rollers, of which the following is a specification.

' My invention is an improved inking roller.

The object o f my invention is to provide an inking roller, which may be continuously fed with additional ink, as required, without removing the roller from the machine.

A further object of my invention is to provide an inking roll` which is adapted to be rotated by a rinting roll or platen and in which the inklng roll is mounted on dead centers and has ink fed through one of the dead centers into the` interior of the roll from which it depresses through a platen to the inking surface.

In the annexed ldrawing in which the preferred form of my invention is illustrated:

Figure 1 is a side view of my inking roller.-

Figure 2 is a longitudinal sectional view of the same.

Referring more particularly to the drawing, my inking roller comprises a pair of heads 1 and 2, which are'journaled upon pin bearings 3 and 4 respectively. These pins are preferably threaded into the frame members 5 and 6,4t0 support the roller, andk also provide an adjustment for wear.

A perforated cylinder 7 is mounted between the heads l and 2, and may be either secured lto said heads, or -formed integral therewith. A feltor similar fibrous pad 8 surrounds the cylinder 7, and a cloth strip 9 surrounds the pad 8 against 4which the printing rolll() presses. A

A tube 11 extends through the pin 4, and

head 2, into the cylinder 7, and a suitable container, such as the cup 12, is secured to sald tube above the level of the inking roll.4 Thus the ink placed in the cup is fed by gravityto the perforated cylinder 7, from whence it is evenl distributed through the perforations thereln to the pad 8 and thence to the cloth cover 9.

A stopper 13 is provided in the tube 11 at the outlet of the cup 12, which is controlled by a handle 14 extending through said cup. A valve 15 is also provided in the tube 11 to stop the ow of ink therethrough.

It will be notedlthat the pinxgbearings 3 and 4 form conical dead cente hich engage in the cones on the head and 2 of the roll, the ink carrying tube passing completely through the bearing 'pin 4 and the cone on the head 2 does not retard the rotation of the roller. By means -of the feed support of the bearingpins 3 and 4 in the free members 5 and 6 4a frictional resistance can be made against the cones of the heads l and 2in order to partially retard o-r free the rotation of the inking roll.

Having described my invention, I claim:

1. An inking roller comprising in combination a pair ofheads each having a coned bearing surface, a erforated cylinder between said heads, al brous pad surrounding the cylinder, stationary screw threaded bearing pms having conlcal ends engaging the coned bearing heads, a tube passing through one of the bearing pins and through one of the heads, and means-to feedv ink ,through the said tube.

2. An inking roller as claimed in claim 1. having in addition screw threads on the bearing pins, and a frame in which said pins are adjustable to increase or decrease the .frictional resistance of the rotation of the roller.

In testimony whereof I atx my signature.

' JAMES F, PERKINS.
