Breech loading sporting arms and pistols having drop down barrels and manual sliding extractors.

A form of bolt action long arm.

A center fire cartridge for the split cylinder conversion system.

A method of combining a detachable breech piece with the cylinder of a revolver. This was the split cylinder conversion for permitting the use of metallic cartridges in arms originally designed for the percussion system.

There was a disclaimer filed by the Birmingham Small Arms Company on September 9th 1873 which removed the first claim as it was not considered to be new and original, and removed the second claim as it was not considered to be as benificial to the public as first considered. It appears Tranter handed the patent rights over to the BSA on the condition they take no legal action against Westly Richards and the National Arms and Ammunition Co. both of the same address in respect of the manufacture, use or sale of cartridges for any alleged infringement of the patent as ammended by the disclaimer.
