ABSTRACT:
FIELD OF THE INVENTION
The invention relates to hammers and in particular to a means for reinforcing, and providing a striking surface on, the butt end of the hammer.
SCOPE OF THE PRIOR ART
It is not uncommon for craftspeople such as carpenters or bricklayers to use the butt end of a hammer for certain applications, such as to tap bricks into alignment in mortar when bricklaying. This tapping deforms and damages the hammer handle so as to lessen the utility of the hammer as well as the comfort of the handle.
Although hammers and hammer handles are known in the art, there is a need for a hammer with a grip and an integrally attached striking cap, which provides a striking surface which is harder than the grip material. It is the integral attachment of the striking cap to the hammer which imparts an improved durability to the hammer handle as compared to the prior art hammer handles, and which provides an improved striking surface to the hammer as compared to prior art hammers where the handles are constructed entirely of grip material.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a novel reinforced hammer wherein the butt end of the hammer is at least partly protected from striking damage while providing a resilient striking surface.
It is a further object of the invention to provide a novel hammer handle having a harder surface on the butt end than that provided by the grip material.
It is a further object of the invention to provide a method for making the novel hammer of the invention.
Other objects and advantages of the present invention will become obvious to the reader and it is intended that these objects and advantages are within the scope of the present invention.
The novel hammer of the invention is a hammer having a reinforced handle, wherein the handle includes a grip and an integrally attached striking cap at least partially embedded in the grip. The striking cap is of a material harder than the grip, and provides the hammer with a striking surface at the butt end of the handle. The striking cap may farther have at least one rib or groove, which serve to more strongly affix the striking cap to the hammer. The invention also includes a reinforced grip, and a method of manufacture of the hammer of the invention.
