An internal reset system for paint ball markers. A hammer body as modified rearwardly to include an axial opening to receivably retain the forward head of a reset rod. The forward portion of the reset rod is thus free to reciprocate within the axial opening, but restrained, during the reset phase, when the head of the reset rod internally encounters a flange at the rear of the axial opening. In this phase the reset rod carries the hammer to the reset position, compressing a spring, where it is retained by the trigger sear ready for the next firing. The rear end of the reset rod is affixed to a back block that mechanically connects the modified hammer assembly and the marker bolt. In one embodiment the hammer is modified by a hammer sleeve, attached rearwardly to the hammer body and having an axial opening for the head of the reset rod.

What is claimed is: 1. A paint ball projectile marker comprising: a bolt chamber and barrel through which a projectile is received and expelled; a bolt in said bolt chamber sealably reciprocable between a first rearward reset position to accept said projectile into said bolt chamber to a second forward firing position wherein said projectile is expelled forwardly from said barrel by pressurized gas; a hammer chamber connected to and parallel to said bolt chamber; means connecting said bolt and a hammer assembly for simultaneous movement; said hammer assembly comprising: a hammer body reciprocable in said hammer chamber from said reset position to said firing position, said hammer body including a sear lug; a reset rod, a forward head of said reset rod being axially and reciprocably retained in an opening in said hammer body, a rearward end of said reset rod being affixed to said means connecting said bolt and hammer; a hammer spring normally biasing said hammer body towards said firing position; means to supply projectiles into said bolt chamber in said reset position; a handle and trigger assembly, said trigger including a pivotal sear releasably connected to said sear lug to retain said hammer body in said reset position against said hammer spring bias; means to supply pressurized gas ultimately to said bolt chamber via a control valve positioned forwardly of said hammer body, said control valve comprising a valve pin normally spring biased to close said valve, said valve pin extending rearwardly into said hammer chamber in said reset position, whereby said hammer body when released will strike said valve pin to open said valve and supply said pressurized gas to said bolt chamber to expel said paint ball projectile; and means timed to connect with said pressurized gas to force a connected assembly of said bolt, said means connecting said bolt and a hammer, said reset rod and said hammer body to said reset position. 2. The paint ball projectile marker of claim 1 wherein said hammer body includes a hammer sleeve rearwardly connected to said hammer body, said hammer sleeve having an axial opening to receive and slidably retain said forward head of said reset rod, said opening including rearward flange means to support said forward head of said reset rod in order to move said hammer body and hammer sleeve to said reset position. 3. The paint ball projectile marker of claim 2 wherein said rearward means to support said forward head is a transverse flange projection. 4. The paint ball projectile marker of claim 1 wherein said rearward end of said reset rod is threadably attached to said means connecting said bolt and hammer. 5. A paint ball projectile marker comprising: a bolt chamber and barrel through which a projectile is received and expelled; a bolt in said bolt chamber sealably reciprocable between a first reset position to accept said projectile into said bolt chamber, to a second firing position wherein said projectile is expelled forwardly from said barrel by pressurized gas; a hammer chamber connected to and parallel to said bolt chamber; a back block exteriorly and rearwardly connecting said bolt and a hammer assembly; said hammer assembly comprising: a hammer body internally reciprocable in said hammer chamber from said reset position to said firing position, said hammer body including a lug; a reset rod, a forward end of said reset rod having an enlarged head that is axially retained in said hammer body, a rearward end of said reset rod being affixed to said back block; a hammer spring normally biasing said hammer body towards said firing position; means to supply projectiles into said bolt chamber in said reset position; a handle and trigger assembly, said trigger including a pivotal sear releasably connectable to said lug to retain said hammer body in said reset position against said spring bias; means to supply pressurized gas ultimately to said bolt chamber via a control valve positioned forwardly of said hammer body, said control valve comprising a valve pin normally spring biased to close said valve, said valve pin extending rearwardly into said hammer chamber in said reset position, whereby said hammer body can strike said valve pin to open said valve and supply said pressurized gas to said bolt chamber to expel said paint ball projectile; and means connectable with said pressurized gas, after said projectile is expelled, to force a connected assembly of said bolt, said back block, said reset rod and said hammer body to said reset position. 6. The paint ball projectile marker of claim 5 wherein said hammer body includes a hammer sleeve rearwardly connected to said hammer body, said hammer sleeve having an axial opening to receive and slidably retain said enlarged head of said reset rod, said opening including a flange means, at the rearward end of said sleeve, to connect with and transport said reset rod, said hammer body and hammer sleeve to said reset position. 7. The paint ball projectile marker of claim 6 wherein said hammer sleeve is threadably connected to said hammer body. 8. An internal reset system for paint ball projectile markers of the type having a first chamber for a bolt and a parallel second chamber for a hammer assembly, and means to connect said bolt and said hammer assembly for substantially simultaneous movement in their respective chambers from a rearward reset position to a forward firing position of said marker, the improvement in said hammer assembly comprising: a hammer body, said hammer body including sear lug means to releasably retain said hammer body in said reset position, a reset rod, a forward head of said reset rod being axially and reciprocably retained in said hammer body, a rearward end of said reset rod being affixed to said means connecting said bolt and hammer assembly; and a hammer spring normally biasing said hammer assembly towards said firing position. 9. An internal reset system of claim 8 wherein said hammer body includes an axial opening to receive and slidably retain said forward head of said reset rod, said opening including rearward flange means to support said forward head of said reset rod in order to move said hammer body and hammer sleeve to said reset position. 10. An internal reset system of claim 8 wherein said hammer body includes a hammer sleeve rearwardly connected to said hammer body, said hammer sleeve having an axial opening to receive and slidably retain said forward head of said reset rod, said opening including rearward flange means to support said forward head of said reset rod whereby said hammer body and hammer sleeve are returned to said reset position. 11. An internal reset system of claim 10 wherein said hammer sleeve is threadably connected to said hammer body.
