Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
A swivel tooth brush comprising: an elongated handle provided with a transverse bore forming a smooth bearing surface adjacent one end and a longitudinal bore terminating in said transverse bore, shaft means within the bearing including a pair of axially spaced readially enlarged shaft portions and an intermediate gear-like member of smaller diameter than the shaft portions, said shaft portion being closely fitted to the smooth bearing to protect the member against dirt or external effects, a spring biased locking-pin within the longitudinal bore having a wedge-shaped end normally located between a pair of teeth on the gear-like member for locking said shaft means in selected positions, and a brush mounted on one end of the shaft means extending from the transverse bore, said brush being oblique relative to the axis of said shaft means.
