He envisioned it as being a fully automatic rifle in order to replace the bolt-action service rifles then in use (such as the American M1903 Springfield ).
Any real advantages to the system were far outweighed by the additional cost of manufacture associated with the device. Also, in the Thompson submachine gun the H-shaped bronze lock connects the bolt actuator to the bolt body; incorrect installation of the Blish lock can render a Thompson inoperable upon firing.
Auto-Ordnance Corporation was created by John T. Thompson in August 1916 with the backing of investor Thomas Ryan.
