Abstract
Abstract A hollow metallic head having a ball striking front face and a bottom surface, (b) the head defining an opening between the hollow and the exterior, the opening located at the bottom of the head, the head having a heel and toe, (c) and a closure for that opening having elongated, tongue and groove, linear sliding connection with the head, the closure located at the bottom of the head, the closure directly exposed along its length to the head hollow above the closure, (d) the connection having a substantially T-shaped cross section, the closure being longitudinally elongated in the direction between the hell and toe, and the connection comprising two pairs of tongue and groove elements, each pair including a tongue element on the closure and a groove element on said head to limit inward displacement of the tongue elements, the closure having a lowermost outer surface everywhere spaced from the tongue and groove elements and flush with the head bottom surface at opposite sides of the closure lowermost outer surface, the closure entirely confined within the outer perimeter outline of the head.

Claim 1
Independent Claim
202 words
In a golf iron, the combination comprising (a) means defining a hollow metallic head having a ball striking front face and a bottom surface, (b) the head defining an opening between the hollow and the exterior, the opening located at the bottom of the head, the head having a heel and toe, (c) and a closure for said opening having elongated, tongue and groove, linear sliding connection with said means, said closure located at the bottom of the head, the closure directly exposed along its length to the head hollow above the closure, (d) said connection having a substantially T-shaped cross section, the closure being longitudinally elongated in the direction between said heel and toe, and said connection comprising two pairs of tongue and groove elements, each pair including a tongue element on the closure and a groove element on said head, the grooves having shoulders adjacent the head hollow to limit inward displacement of the tongue elements, and the closure having a lowermost outer surface everywhere spaced from said tongue and groove elements and flush with said head bottom surface at opposite sides of the closure lowermost outer surface, the closure entirely confined within the outer perimeter outline of the head.
