Abstract

A hammer head with an internal cavity including weights that are sized to restrict the weights from escaping from a crack in the hammer or are easily collected and accounted for should the hammer separate to ensure foreign objects and debris do not contaminate sensitive work spaces. The weights are shaped to allow the weights to longitudinally move in the internal cavity. The weights may take the form of a number of different shapes.

First claim

What is claimed is:

1 . A hammer head, comprising:
a body having first and second ends; an end cap coupled to the second end; an internal cavity formed in the body and having a longitudinal axis; a guide rod disposed in the internal cavity and extending longitudinally along the longitudinal axis; and a weight including a through hole, wherein the weight is disposed in the internal cavity and the guide rod extends through the through hole, where in the weight is longitudinally moveable along the guide rod.

2 . The hammer head of claim 1 , wherein the weight has a shape that substantially corresponds to a cross sectional shape of the internal cavity.

3 . The hammer head of claim 1 , wherein the guide rod has a guide rod length that substantially corresponds to a cavity length of the internal cavity.

4 . The hammer head of claim 1 , wherein the weight includes more than one weight, and a combined length of the weights is less than a cavity length of the internal cavity.

5 . The hammer head of claim 1 , wherein the weight includes more than one weight, and the weights are linearly arranged relative to each other along the longitudinal axis.

6 . The hammer head of claim 1 , wherein the weight is substantially disc shaped.

7 . The hammer head of claim 1 , wherein the end cap is releasably coupled to the second end.

8 . A hammer head, comprising:
a body having first and second ends; an end cap coupled to the second end; an internal cavity formed in the body and having a longitudinal axis; and weights disposed in the internal cavity and arranged linearly relative to each along the longitudinal axis.

9 . The hammer head of claim 8 , wherein each of the weights has a spherical shape that substantially corresponds to a cross sectional shape of the internal cavity.

10 . The hammer head of claim 8 , wherein a combined length of the weights is less than a cavity length of the internal cavity.

11 . The hammer head of claim 8 , wherein the end cap is releasably coupled to the second end.

12 . A hammer head, comprising:
a body having first and second ends; an end cap coupled to the second end; an internal cavity formed in the body and having a longitudinal axis; and weights longitudinally disposed in the internal cavity, wherein each of the weights includes a deformable end.

13 . The hammer head of claim 12 , wherein each of the weights has a rod shape.

14 . The hammer head of claim 12 , wherein each of the weights has a weight length that is less than a cavity length of the internal cavity.

15 . The hammer head of claim 12 , wherein the weights are disposed adjacent to each other in the internal cavity.

16 . The hammer head of claim 12 , wherein the deformable end is tapered.

17 . The hammer head of claim 12 , wherein the end cap is releasably coupled to the second end.
