Royal Navy Innovation

1920: Nasmith-Lockhart Slide Rule.24

As creative as ever, among the earliest inventors of this period reappears Nasmith. However, this time he teamed with another officer. His first post-war creation was known as the Nasmith-Lockhart Slide Rule.25 Nasmith was at this time a Captain in command of HMS Lucia and the submarine flotilla fighting the Bolsheviks in the Baltic. Anthony Bevis Lockhart DSC was a Lieutenant Commander in the flotilla. The purpose of the slide rule they invented was to find inclination or angle on the bow by taking vertical and horizontal angles of the target.

This was apposite, for back in 1903 Barr and Stroud had been approached by the Holland Torpedo Boat Company to design a rangefinder for submarine periscopes. The company was a natural choice for it was making most of the Navy's rangefinders and had a close working relationship with the Admiralty. However, there was no apparent enthusiasm from the Admiralty so any ideas were not taken to a design stage.26 Then, in December 1915 Commodore Sydney Hall, the Inspecting Captain Submarines,27 met Barr and Stroud's Chief Scientific Assistant, James French, to resurrect the earlier rangefinder work. The company

took a standard rangefinder, turned it through 90°, and mounted it vertically in the periscope. A mock-up was made and shown to Hall in July 1916 and shortly afterwards the company received orders for 13 FY1 range-finding periscopes.28 The first FY1 periscope, using a stadimeter was fitted in the minelayer submarine M3 within a year of being ordered in 1919.29 At the time Nasmith and Lockhart were in the Baltic so they may have been unaware.

Shortly afterwards, in the early 1920s, a periscope was developed that had the added advantage of being able to range in the horizontal plane as well as the vertical plane so if the target's length was known, the angle on the bow could be determined from the virtual length and thereby the target's course.30 This horizontal capability would have fulfilled Nasmith and Lockhart's ambitions but for reasons unknown it disappeared from later periscopes.
