Torpedo Director Pattern 1192
The Torpedo Director Pattern 1192, sometimes referred to as a "broadside director"[1], was a large, semi-circular British torpedo director designed for use with training broadside tubes. It entered service some time before 1903.[2]
Seemingly, it was a contemporary instrument to the Pattern 1193,[Inference] which had a 60 degree arc and was used for fixed tubes and dropping gear.
Design
It was likely scaled for torpedo speeds of 12 to 40 knots and enemy speeds of 0 to 30 knots.[3]
If a Pattern 1192a existed, it would have been similar, but made stronger in its pivots and sighting bar.[4]
Adaptation
In 1903, it is likely that the sight bar was etched with a scale to permit maximum range for firing to be calculated by arithmetic.[5]
In 1909, some were fitted with tangent bars and regraduated to 2/3rd scale for use from TBD fore bridges and heater torpedoes.[6]
It was no longer used in any modern ships as of 1912.[7]
As of 1916, it was noted as still being in use in the H.M.S. Pelorus class.[8]
