Oakland Underfoot

Poking around Oakland’s old downtown has yielded some more overlooked old things. Take P. H. Jackson’s Device for Plentiful Ventilation, on Harrison south of 14th Street.

Somehow I don’t think it’s functioning any more. This is the same Jackson I featured two weeks ago. I found another configuration of ventilator from the Jackson company, this one with a patent date of 1893.

And this one has a patent date of 1895.
