Abstract
Abstract An elongated rod, such as a golf putter, has a permanent magnet secured at one end. A golf ball position marker of magnetic material is releasably held on the end of the putter by the magnetic attraction between the magnet and the material of the marker. The marker is placed in position by maually lowering the end of the putter carrying the marker onto the surface of the putting green exerting pressure on the putter to press the marker into place. The putter is then moved parallel to the surface of the green to slide it off of the marker, the marker being retained in position by a projection on the lower side engaging the surface of the green. The marker is removed by bringing the magnet back into contact with the marker and then lifting it vertically to pull the marker away from the surface of the green.

Independent Claim
267 words
A method of placing a golf ball position marker in position on a putting green without bending by the user, which method comprises: a. providing a golf club putter having a golf club putter head at the one end with a bottom surface, the golf club putter head containing a permanent magnet, the outer surface of the magnet being substantially flushed with the bottom surface of the golf club putter head; b. providing a golf position marker which comprises a material which will adhere to the permanent magnet in the golf club putter head, the marker having a ground engaging projection extending from one surface thereof; c. manually placing without bending the golf ball position marker into contact with the permanent magnet in the golf club putter head to retain the marker in position solely by magnetic attraction between the marker and the magnet; d. manually lowering the golf club putter head with the marker to the surface of a putting green and to and above a position on the putting green which is to be marked; e. pressing the ground engaging projection of the marker into the desired position on the putting green by manually exerting sufficient pressure downwardly on the other end of the golf club putter; and f. sliding the golf club putter head in a lateral direction generally parallel to the surface of the putting green until said magnet has slid sufficiently out of contact with the golf ball position marker, so that the golf club putter head may be removed and the marker left in the desired position on the putting green.
Claim 5
Independent Claim
267 words
A method of placing a golf ball position marker in position on a putting green without bending by the user, which method comprises: a. providing a golf club putter having a golf club putter head at the one end with a bottom surface, the golf club putter head containing a permanent magnet, the outer surface of the magnet being substantially flushed with the bottom surface of the golf club putter head; b. providing a golf position marker which comprises a material which will adhere to the permanent magnet in the golf club putter head, the marker having a ground engaging projection extending from one surface thereof; c. manually placing without bending the golf ball position marker into contact with the permanent magnet in the golf club putter head to retain the marker in position solely by magnetic attraction between the marker and the magnet; d. manually lowering the golf club putter head with the marker to the surface of a putting green and to and above a position on the putting green which is to be marked; e. pressing the ground engaging projection of the marker into the desired position on the putting green by manually exerting sufficient pressure downwardly on the other end of the golf club putter; and f. sliding the golf club putter head in a lateral direction generally parallel to the surface of the putting green until said magnet has slid sufficiently out of contact with the golf ball position marker, so that the golf club putter head may be removed and the marker left in the desired position on the putting green.
