“Hill’s Patent” Stanley Bull-Dog Revolver: Blatant Patent Theft in 1878

The Stanley Bull-Dog revolver is an English-production revolver which is marked as being “Hill’s Patent”. The gun uses an interesting simultaneous ejection system similar to the Fagnus – which one assume was the subject of Hill’s aforementioned patent. The guns were made in a variety of configurations (blue, nickeled, various barrel lengths and calibers, etc).

Hill’s actual patent (number 3645 of 1878) is actually a provisional patent relating to the lockwork that turns the cylinder. In fact, the ejection system used on the guns was invented by a Belgian named Jean Mathieu Deprez-Joassart five years earlier in 1873. Deprez-Joassart did patent the mechanism, and Hill appears to have simply claimed the system as his own and convinced a British gunmaker to pay him royalties for guns made with it.

Thanks to Select Fire Weaponry of Waukesha, Wisconsin for loaning me this revolver to film.

    • And the assassin thought “I’m a REAL Republican!! Surely the Republican Party will just pull strings, so I get out of jail free and into a cushy desk job in Washington after that Goody Two-Shoes Garfield kicks the bucket!”

      • Garfield is fine (The orange cat) he meant a 19th c U.S president; who was shot by an “Office seeker” a disapointed one, clearly; apparently “To the victor belong the spoils” type thing; er… Well a new country really, you are going to get these issues as oppose in a long standing “Tongue in bumhole” established type patronage system such as in, the country said new country broke away from a bit back; not that long ago, really. Sooo… Shit happens.
