Description
Z
Background of the Invention , In recent developments in the printing arts, the standard inking arrangement which includes an ink supply roller partiall~ immersed in ink has been xeplaced by a hollow ink supply roller which is filled with ink. These hollow ink supply rollers are generally provided with holes spaced about the circumferen~e thereof, and an exterior, permeable coating which limits the ink flow to the exterior and provides a smooth ink transfer to a transfer roller or to the indicia characters directly. These rollers are also provided with a vent arrangement which permits air to enter the roller and replace the ink as it is used.
These hollow ink supply rollers have suffered from significant drawbacks which have severely limited their usefulness. A material which provides consistent print density during repeated use will usually become sat-urated during prolonged periods of non-use. Using the rol-ler again after such a period of non-use will result in sever-ely overinked imac3es and blotchirlg. Also, conventional vented rollers have a tendency to leak through their vent holes during prolonged rest periods.
Furthermore, these rollers exhibit a gradual decline in the print density over their useful life, so that the print image gradually degrades and becomes more and more difficult to read. Although human readers can usually adjust to the degraded image, machine readers, such as Optical Char-acter Recognition ~OCR) devices usually cannot. Thus the point at which the machine reader begins to misread the fad-ing images is difficult to determine until signi~icant èrrors have occurred.
~121~2 To overcome the ventin~ problem, solid sintered plastic rollers, spongy open-celled rubber~rollers, and the like have been suggested in the prior art. These construc-tions exhibit the same print density degradation as noted in the foregoing. Furthermore, many of them still leak or cause blotching. . ~

The ink supply roller does not cause blotching or over-inking after rest periods, and has no vent hole to leak. Further-more, it is not subject to seepage during normal changes in ambient or atmospheric pressure.
The ink roller of the present invention is formed of a cylinder fabricated of a microporous material, such as sintered, ultra-high molecular weight polyethylene or similar organic or inorganic material which is hermetically sealed at both ends. The cylinder contains an ink supply of selected viscosity which is drawn through the wall of the roller by capillary action of the micropores in the wall. As the ink is removed from the micro-porous material by a transfer medium, ink flows from the reservoir by capillary action to replace the used ink. Removal of ink from the reservoir results in a slight pressure drop, with the result that outside air will be drawn through the micropores of the material in order to return the system to a condition of equili-brium.
The invention further includes the use of a soft microporous sleeve secured about the roller. The print characters impinge on the sleeve directly, compressing a portion of the soft material. As the compressed area expands after contact, it draws ink out of the roller wall to replace the ink just removed. Ink is drawn out of the reservoir by the capillary action of the micropores in the wall, and the system returns to equilibrium as the decreased . . . . . . . . . . . . . . . . . . . . . . . . . .

pressure of the reservoir draws air into the system. The sleeve arrangement has the added advantage that it does not require a transfer roller to lnk the print characters, and therefore does not require the initial cycling needed to bring a transfer roller up to uniform inking. Furthermore, the sleeved roller requires less parts in conjunction with a printing device, as the transfer roller is eliminated entirely.

Description of the Preferred ~mbodiment As shown in Figure 1, one embodiment of the pre-sent invention comprises an inking roller 11 which is used to provide ink directly to indicia forming print characters.
The roller 11 includes a cylinder 12 fabricated of a micro-porous material such as sintered, ultra-high molecular weight polyethylene. Other microporous materials of metal or other materials might be used. The thickness of the cylinder wall where the material is polyethylene is appro-ximately 0.065 inches (1.65 mm), and the micropore diameter i~ uniform, ranging between 2 and 70 microns. T~ metal i8 used, the wall thickness may be as low a~ about 0.010 inches, with the micropore diameters being about 10 mi~rans. For softer materials, the wall thickness might be in excess of .070 inches, and the micropore diameters over 40 microns.
The ends of the cylinder 12 are sealed to provid~ a chamber therein, such as by the use of end caps 13. Each end cap is provided with an axially disposed, outwardly extending shaft 14 which engages the roller carrier arm~ 16 normally pro-vided in a printing device.
Disposed within the cylinder is a reservoir of printing ink, the ink having a viscosity at 70P of appro-xi~ately 1000 cps and a range of 100-5000 cps, depending on the nature of the microporous material. Disposed about the cylinder is a sleeve lB formed of a microporous material, such as elastomer or rubber. The sleeve wall in the prefer-red embodiment is approximately 0.040 inches (1.03 mm) thick, and the porosity is selected so that the ink may pa~s there-through. The sleeve covers almost the entire axial extent of the cylinder, and i8 adapted to impinge direct~y on an indicia forming print character.
As shown in Figures 2 and 3, as a.print head 23 translates tangentially with respect to the roller 11, the print characters 21 impinge on the sleeve 18 of the roller, and are thus inked. The tangential velocity of the print head imparts a rotational motion to the roller, and the radial co~ponent of the print head velocity compresses the portiDn 22 of the sleeve which has contacted the print characters.
As the compressed portion 22 expands and returns to its original shape by natural resilience, the suction created thereby draws ink out of the roller wall 12. ThiR
ink is replaced in the wall 12 by capillary action of the micropores in the wall 12. As many printing cycles are completed, this removal of the ink from the interior of the roller creates a decrease in the pressure inside the roller. When the decrease in pre~sure becomes sufficient to overcome the resistence of the ink in the wall of the sintered tube, air i~ drawn into the roller through the sintered wall ~mtil the pressure equilibrium is ree3tabli8h-ed.
Also, tests have shown that the roller 11 exhi-bits a marked dropoff in print intensity at the end of its useful life, while maintaining a constant print intensity prior to that time. For example, roller~ according to the present invention have successfully completed more than 140,000 print cycles yielding uniform print lntensity, and then have failed within the next 5000 print cycles to the point of illegibility. This rapid dropoff makes it very ea~y to ascertain when roller replacement is required.
Another advantage of the unique construction of the roller 11 is that the micropores of the sleeve and the cylinder~wall are saturated with ink, and are always ready to print. Also, no transfer roller is required to apply the ink to the print ch~racters. Thus no "warm-up time"
is needed to bring the inking system using the roller 11 to the point where the print density is uniform. Even after an extended re~t period, the roller 11 will create a dense printed character, without blotching or overinking.
As shown in Figure 6, another embodiment of the present invention comprises a roller assembly 31 for ink-ing printing characters. It includes a cylinder 32 fabri-cated of a microporous material, such as sintered, ultra-high molecular weight polyethylene. The wall of the cy-linder has a thickness in the range of 0.060 to 0.070 inches (1.5 mm - 1.8 mm), and a porosity in the range of 2-70 mi-crons. Secured to the ends of the cylinder 32 are a pair ~f end caps 33 with a stub shaft 34 extending from the cen-ter of each one. The cylinder and end caps define an ink-ing roller havi.ng a single sealed chamber therein which is filled with a quantity of printing ink 39. The ink has a viscosity in the range of 100-5000 cps at 70F.
The roller assembly also includes a pair of rol-ler support arms 36, each being provided with a slot 37 which receives the stub shafts 34 of the end caps 33. A
transfer roller 38 is also provided, supported in rotating fashion by the distal ends of the arms 36 and maintained in rolling contact therewith. The transfer roller is formed of a thick cylinder 42 of soft rubber or similar elastomer (10-45 Shore D durometer) secured about a central sup-port shaft 43. The shaf~ 43 is secured with its ends re-ceived through the arm~ 36. A pair 3f springs 41 disposed within the slots 37 ~esiliently biases the inkin~ roller _g_ Lt~
into engagement with the tran~fer roller.
The capillary action of the micropores of the cylinder wall draws ink into the micropores. Yet the cy-linder feels dry to the touch and does not easily transfer ink to the human skin. In each printing cycle the transfer roller impinges on the printing characters of the printing head to trans~er ink thereto. At the same ~ime it is ro-tated by the print head and urged into contact with the inking roller to pick up more ink. The soft rubber of the transfer roller compres~es in the area 44 irnpinging on the inking roller, as shown in Figure 8. As the print head disengages the transfe~ roller the area 44 expands, creat-ing a local area of reduced pressure in the cylinder wall.
The reduced pressure draws more ink to the surface of the inking roller to replace ink taken up by the transfer rol-ler. After many printing cycles and a concomitant reduc-tion in the ink supply within the cylinder, the pressure therein is reduced. Air then enters the micropores under the urging of the pressure differential until the pressure equilibrium is reestablishe~.
It i~ a significant characteristic of this embodi-ment of the present invention that although the inking roller feels dry to the touch, the transfer roller may draw ink to the surface of the inking roller and take up that ink.
Furthermore, this embodiment of the invention also exhibits the ability to provide a unifor~ print den-sity over the useful life of the in~ing system, and al50 exhibits a sharp decline in print density when the ink supply is exhausted. For example, inXing asse~blies 31 have completed 100,000 printing cycles without any appre-ciable variation in image intensity, and have fa;led to the point of illegibility within the next 5000 cycles.
This sustained uniform density and rapid dropoff are highly desirable characte~istics in ~any printing appli-cations.
