Tonight's bedtime reading is A treatise on the theory of screws. Or perhaps the earlier work Theory of screws: a study in the dynamics of a rigid body

My favourite Robert Stawell Ball article is "Further development of the relations between impulsive screws and instantaneous screws..."
Carol Maddock said:
But all joking about impulsive screws aside, Ball was a fascinating man, and we're very lucky to have his photos at Library Towers:
Ball was a very talented amateur photographer. His membership until 1911 of the Commissioners of Irish Lights inspection committee that circumnavigated the Irish coast each year gave him the opportunity to capture many splendid images, not only of lighthouses and other navigational facilities, but also of everyday life in the more remote coastal areas. Many of these photographs are held in the National Photographic Archive (NLI).

Not sure that they’re antennae, seems Mizen Head operated fog signals from 1909, a radio beacon from 1931 www.irishlights.ie/tourism/our-lighthouses/mizen-head.aspx

Three men and a three-legged dock-tailed Dog. History and details - www.irishlights.ie/tourism/our-lighthouses/mizen-head.aspx . Surprised to see the bridge dates from 1907. catalogue.nli.ie/Record/vtls000741407/HierarchyTree?recor...
John Spooner said:
i suspect that what we can see are not antennae but supports for the actual antennae, which would be in the form of long wires, required for the longer wavelengths which would be all that was available in the early 20th century.. I no longer think this.

We will award (at our own expense), half a dozen (virtual) sticky buns to the first person who tells us what exactly the Type ZW1 does and what is the application that the Commissioners of Irish Lights may have put it to?
Suck Diesel said:
“AI Overview
The images depict a double diaphragm submarine emitter, labeled as Type ZW1, with a sound output of 250 watts. Figure 31 shows a diagram of the emitter, highlighting its internal components marked A and B. Figure 32 is a photograph of the emitter itself.”
Suck Diesel said:
Wild guess, is this attached to a ship to identify itself to a submarine that it caries medical or other non hostile supplies?
National Library of Ireland on The Commons said:
Suck Diesel Plausible, but I would need some evidence.
Suck Diesel said:
Of course, ‘submarine’ just means underwater, not necessarily a U-boat.
I don’t think that Irish Lights has anything to do with U-boats so this device is used to emit a sound underwater, but purpose unknown
