Abstract
A impact hand stamping tool 10 has an imprint member 14 with an elongated hand stamp element 16 slidably mounted in a supporting sleeve element 18. The hand stamp element extends from an anvil end 50 to an imprint end 46 having a symbol face 48. The hand impact tool 10 has a plunger member 70 with an elongated forward end 74 having an anvil surface 76 for engaging the anvil surface 52. An elongated coil spring 90 has reduced diameter spring ends 94 and 96 mounted in corresponding spring latching grooves 26 and 84, respectively. Each of the members 14 and 70 have finger gripping sections 26 and 84 that are formed with a series of annular grooves 100 forming finger rings 102 for enabling the user to easily grip and hold the tool member 14 during the operation of the tool and the expansion of the coil spring prior to the release of the plunger member 70. Upon release of the plunger member, the anvil surface 76 of the forward end 74 is driven into the anvil end 52 driving the hand stamp element 16 to imprint the work surface 12. The number of rings 102 in the finger gripping section 102 is less than the number of rings 102 of in the finger gripping section 24 to minimize premature release of the sleeve element prior to the release of the plunger member 70.
