  • the main piston member 43 has the pilot portion 27 thereon which projects into the opening in the plate 25. It should be apparent, of course, that upon reciprocating movement of the member 11 of the engraving press, the member 11 will apply a force to the piston members 42, 43 to effect movement thereof.
  • the fluid supply 17 is connected by the conduit 18 to the ink injector unit 15.
  • the conduit 18, as shown in FIG. 4, communicates through a suitable connection, generally designated 48, with a passageway 49 located in the piston member 43.
  • the passageway 49 extends longitudinally of the piston member and contains at its outer end, or lower end, as shown in FIG. 4, a reciprocating piston unit, which is generally designated 50.
  • the piston unit 50 which is reciprocable in the bore 51 in which it is contained is a hollow structure and includes a cylinder member 52 which is received in the bore 51 and is slidable therein.
  • the cylinder member 52 at its upper end has an opening 53 therein which communicates with the fluid supply. Accordingly, it should be apparent that the fluid can flow from the fluid conduit 18, as shown in FIG. 4,.
  • the fluid which flows into the hollow cylinder member 52 may flow therefrom through suitable openings 60 in the lower end of the member 52 and into an outlet chamber 61 defined in part by the housing member 40.
  • the entire unit 14 is carried with that member 11 and the die plate 16 engages the material 13 and effects a seal therewith.
  • the seal is effected primarily in the areas surrounding the recess formed in the die plate 16. Further, downward movement of the member 11 after the die plate 16 engages a material 13 and effects a seal therewith and causes the injector piston assembly 42 to move downwardly relative to the housing members 40, 41 and relative to the die plate 16.
  • This downward movement results in the lower end of the piston, designated 65, moving into the chamber 61.
  • Initial movement of the piston 65 causes a portion 66 thereof to slide over the openings 60 in the member 52 and thereby effect the closing of the openings 60.
  • This structure in effect, comprises a slide inlet valve for the chamber 61.
  • the chamber 61 then becomes a closed fluid chamber having a speciflc charge of a predetermined amount of fluid therein. This is due to the fact that the piston .65 is located a predetermined distance from the end wallor lower wall of the member 40 which defines chamber 61 when the openings 60 are closed thereby. Further movement of the lower end 65 of the piston then increases the pressure of the fluid in the chamber 61. As the pressure of the fluid in the chamber 61 increases, that pressure acts on a conical surface 69 on the lower end of the member 52. The fluid pressure will increase sufficiently so as to cause a retracting movement, that is, a movement of the member 52 into the piston against the bias of the springs 67 and 68 contained in the piston. As a result, the ball valve member 70 moves away from its seat 72 so that fluid is then ejected from the chamber 61 and through outlet openings 73 in the housing member 40.
  • the fluid which flows from the opening 73 flows into a passageway 74 through the gasket 17, and from the passageway 74 flows into a fluid distribution channel v 75 formed in the back side of the die plate 16.
  • the fluid distribution channel 75 has a plurality of openings 76 therein which communicate with the die recess R or design formed in the face of the die plate 16. Accordingly,
  • the fluid injector unit is provided with a pressure release or limiting system.
  • the pressure release system consists of the ball valve 70 which is biased against the lower portion of the member 52 by a spring 80. In the event that the pressure in the system increases above that determined by the spring 80, the ball valve 70 will move away from the lower end of the member 52 and provide for a venting of the pressure, or a release of the pressure to the interior of the piston member 43, thereby, in effect, decreasing the pressure or limiting the pressure that is provided in the recess R.
  • the die plate 16 is provided on the rear surface thereof with a plurality of fluid distribution channels 75.
  • Each of the channels 75 may be connected with a different fluid injector unit 15 and each fluid injector unit may be connected with a different color of fluid.
  • each of the distribution channels 75 formed in the rear side of the plate 17 may have a different color fluid delivered thereto.
  • Each of the distribution channels 75 has a plurality of fluid openings 76 which communicate with the recesses R formed in the opposite side or on the face side of the die plate 16.
  • the openings 76 direct fluid from each of the fluid distribution channels 75 into the recesses, in the form of characters or designs formed on the front face of the die plate 16.
  • Each fluid distribution channel 75 is generally wedge shaped in configuration, as best illustrated in FIG. 4, and is defined by surfaces 86 and 87 which converge as they extend from the back side of the die plate toward the front side of the die plate.

  • the gasket member 17 comprises a substantially platelike member which has a main body portion 90 which is interposed between the plate 30 and the die plate 16.

  • the gap 91 is best illustrated in FIG. 4.
  • the gasket 17 additionally has ribs thereon, generally designated 92 and best shown in FIG. 2.
  • the ribs 92 are formed in the same configuration as the distribution channels 75 in the die plate 16 and are adapted to be positioned within the distribution channels in the die plate 16. Accordingly, the ribs 92 are defined by converging surfaces 93, 94 and which converge as they extend from the main body of the die plate 17.
  • the surfaces 93, 94 convenrge at substantially the same angle as the surfaces 86, 87 converge and, accordingly, the die plate surfaces 93, 94 engage the surfaces 86, 87.
  • the ribs 92 which are formed on the gasket have an end surface 92a which terminates short of the bottom surface 88, and as a result the fluid distribution channel 75, as illustrated in FIG. 4, is defined by the surface 88 and the end surface 92a of the ribs 92, as well as by the lower portions of surfaces 86, 87.
  • each injector unit 15 may communicate with each distribution channel or a plurality of injector units may communicate with a given distribution channel. As shown in FIG. 2 in the dotted lines, the opening 74 extends through the rib 92 in the upper left-hand corner of FIG. 2 and, therefore, communicates with the distribution channel thereat. In the rectangular lay-out in FIG. 2, two ink injectors 15 are illustrated as communicating with the rectangularly configured distribution channel 75.
  • the die plate 17 is constructed with the ribs 92 thereon by molding the die plate 17 directly onto the die plate 16 in stereo form. After the gasket has been molded on the die plate, the gasket 17 is removed therefrom and the outer ends of the ribs are ground down. Moreover, the main body 90 of the gasket is ground down by ten to twenty thousandths of an inch. As a result, when the gasket is located with the rib 92 positioned in engagement with the surfaces 86, 87, the gap 91 is provided.

  • This solid compressed area provides substantial reinforcement of the die plate in this area and tends to minimize working of the die plate and provides for a longer life die plate.
  • the thickness of the main body 90 of the resilient gasket in this condition is the same as the thickness of the resilient gasket 17 as illustrated in FIG. 4.
  • the resilient gasket 17 performs a substantial sealing function in preventing contamination or communication of one fluid distribution channel 75 in the die plate 16 with another.
  • This seal is provided by the fluid-tight sealing contact between the surfaces 93, 94 of the rib 92 and the surfaces 86, 87 defining the fluid distribution channel in the plate 16.
  • this sealing pressure between the surfaces increases when the piston 43 in the fluid injector unit 15 is forcing fluid into the fluid distribution channel, so that the surfaces are not continuously under a high pressure sealing contact, but rather have the greatest sealing pressure at the approximate time.
  • the gasket 16 functions to provide a suction effect on withdrawal of the die plate from the material, and, as noted above, this suction effect provides substantial advantages in the formation of a smooth well-defined character of the material 13.
