  • a spring 56 is positioned around the rod 54 and is arranged to urge the piston toward a retracted position as is illustrated in FIG. 1.
  • Connected to opening 44 is a nipple 58 of a three-way sleeve valve 60.
  • a spring 62 is provided to maintain the sleeve valve in a closed position.
  • the other end of sleeve valve 60 is connected by a flexible conduit 64 to a suitable source of fluid under pressure.
  • the striking tool 18 includes a tubular body portion 66 that is supported in spaced relation to the inner walls of the tubular connecting member by means of annular guides 68 and 70.
  • the guides are suitably secured to the tubular body portion 66 and are movable therewith.
  • a nut 72 is threadedly secured to the end of tubular body portion 66 adjacent the head member 12.
  • the nut has an axial portion 74 through which a supporting member 76 extends into the inner portion of the striking tool body portion 66.
  • the supporting member 76 has a threaded end portion 78 that is secured in the threaded bore 24 of head portion 12. With this arrangement the supporting member 76 remains fixed within the tubular connecting member 16 and the striking tool body portion 66 is arranged to move longitudinally over the surface of the supporting member 76.
  • the supporting member 76 has a plurality of spaced apertures 80 in the periphery thereof forming a circular ball cage in which balls 82 are positioned.
  • An annular ring member 84 is positioned between the outer surface of supporting member 76 and the inner surface of tubular body portion 66.
  • the annular ring has a plurality of ball receiving recesses 86 therein arranged to receive a portion of the balls 82 when the annular ring 84 is moved toward the head member 12 by the inner extending annular shoulder 88 of tubular body portion 66 abutting the annular end portion 90 of ring 84 and moving ring 84 toward the head portion 12.
  • a return spring 92 is arranged to return the annular ring 84 to the position illustrated in FIG. 1 where a shoulder portion of ring 84 abuts the outwardly extending end shoulder 94 of supporting member 76.
  • a hammer 96 is positioned within the tubular body portion 66 and extends into the supporting member 76.
  • the hammer has a striking end portion 98 and an annular recessed intermediate portion 100 in which the balls 82 extend to lock the hammer 96 in a rear or retracted position.
  • the hammer 96 has an enlarged head portion 102 that abuts inturned shoulder portion 106 of the tubular body portion 66 and a striking spring 108 abuts the hammer enlarged head portion 102 and the rear wall 110 of tubular body portion 66.
  • a return spring 112 is arranged to move the tubular body portion 66 to the position illustrated in FIG. 1.
  • the spring 112 abuts the outer turned shoulder 94 of supporting member 76 and the inturned shoulder 106 of tubular body portion 66. As the tubular body portion 66 moves toward the head member 12 the spring 112 is compressed and returns the body portion 66 to the position illustrated in FIG. 1.
  • the portable marking tool operates in the following manner.
  • the sleeve valve 60 is moved forward against the spring 56 and admits fluid under pressure into the cylinder 42 to move the piston 52 and rod 54 axially as illustrated in FIG. 2 and compresses the spring 56.
  • the rod 54 abuts the end portion 110 of the striking tool body portion 66 and moves the striking tool body portion 66 axially toward the head portion 12.
  • the hammer 96 is locked in the position illustrated in FIG. 1 relative to the supporting member 76 and the balls 82 in ball cage extend into the recessed portion 100 of hammer 96.

  • the parts are so dimensioned that the front face 114 of nut 72 abuts the inner shoulder 28 of head portion 12 as the hammer 96 is released from its rearward locked position as is illustrated in FIG. 2. It is believed that the abutting relation of the striking tool body portion 66 with the head portion 12 as the hammer 96 is released and propelled forward provides a structure that transmits the striking force of the hammer 96 through the anvil 20 and markers 36 to the object to be marked and has the desired velocity and force to impress a mark on the object without requiring the object to be positioned in a fixed support or having a mass sufficient to oppose the marking force of the anvil 20.
  • the designation of the apparatus as a portable marking tool is intended to include any types of impressions applied to the surface of various objects and it is not intended to limit this apparatus to the use as an indicia marking tool.
