The Asbury Breech Mechanism

Welcome to the Army Rumour Service, ARRSE

The UK's largest and busiest UNofficial military website.

The heart of the site is the forum area, including:

  1. Is there anyone out there who can tell me who 'Asbury' was?

    He designed the Asbury breech mechanism, but seems to have slipped off the radar completely as soon as he delivered the technology in 1916.

    There is nothing on Google...
  2. At the risk of appearing unhelpful, why not call Fire power, the Gunnery Wing of the RSA or a certain RO in the DRA's office who is Secretary of the RA Historical Society.
  3. Breech Mechanism, Smith-Asbury - Introduced in 1916 and named after its inventors, Lt. Cmdr. George Leonard Smith, USN and Draftsman Dorsey Frost Asbury, both of the Naval Gun Factory at the Washington Navy Yard. This mechanism used gearing to fully open a Welin breech by linking the unscrewing, withdrawing and swinging clear movements into one continuous action and for that reason is sometimes known as a "single motion" breech mechanism. The breech threads are undercut at the start so as to allow the block to swing into position.

    Best I can do.
  4. That's not a bad best!! :lol:
  5. Wha_dar - clearly you rock!

    VMT! :D
