The Philip revolver was revolver designed by W.H. Philip of the United States of America.
W.H. Philip's revolver is an unusual design that allows two or more cylinders to rotate in succession, so that once one cylinder is depleted of ammuntion, the next cylinder will be ready to fire. Each cylinder can hold a total of seven bullets. Philip obtained U.S. Patent #142,175 on August 26th, 1873 for this weapon, and although his design was not unique, it was not successful either.
