Golf ball marker

A marker for use with a golf ball, said marker comprising:

• a housing having two spaced ends, a first of said ends defining an open rim edge dimensioned to support the golf ball,
• a plunger slidably mounted in said housing, said plunger having an enlarged diameter ring at a point between said spaced ends of said housing;
• an end ring secured to the other of said spaced ends of said housing and having a through bore through which a portion of said plunger extends, said plunger being biased in a direction within said housing so that said enlarged diameter ring seats upon said end ring;
• a marking material carried at an end of said plunger so that, upon movement of said plunger toward said golf ball in response to a counter bias exerted against said extending portion of said plunger, said marking material is adapted to contact the golf ball;
• the plunger bias further including a coil spring contained in said housing, one end of said spring biasing against said enlarged diameter ring of said plunger and the other end of said ring biasing against a spring retainer attached to said housing;
• and
• said spring retainer having an angled annular end coaxially disposed inside said open rim edge and adapted to contact the ball, said spring resiliently urges said marking material away from said first end of said housing absent said counter bias exerted upon said plunger.
