"A big riveted iron pipe/smokestack (?) in a 19th century Pennsylvania cemetery"
A: "It looks like it could be a “standpipe”. They were used in municipal water systems from before the 1870’s through the early 20th century to provide a pressure head to maintain water pressure in the system. They were eventually replaced by water towers that could provide pressure as well as volume. The riveted construction would be consistent because in the 1870’s boiler companies that made riveted boilers got into the standpipe business."
They also used to have firing ports in the billboards along the highways.
Ha my thought initially but realized it is being used to cover a hole...(Probably a location for a control panel in a different situation), since it fits so well
We have these in our elevators as well. There used to be a telephone mounted there to call the front desk in case the thing got stuck. Later they got obsolete because there had to be automated warning systems
This is part of the weather station system. There is also a wind speedometer above the plaque. And I confirm that the upper temperature is air temperature and the lower temperature is the road. Warnings, for example about black ice, are also displayed there
