JF Ptak Science Books Quick Post
I've seen a number of novel life boat/vehicles in my travels through patent office records but never really made note of them, which is too bad. They can be pretty interesting in an oddly shared way with 19th century coffin designs and other mortuary patents--specifically the ones having to do with the dead should they find themselves fortunately/unfortunately resuscitated in their sleeping chamber underground. As a matter of fact some of the coffins were equipped with a small belled spire with a wire that went down into the coffin and wrapped around the hands of the dearly departed. So, in the event of premature burial, the undead dead would simply need to move their hands and sound a bell or raise a flag. In any event, that is what came to mind when I saw this image in the Scientific American for August, 1877:
This floating sphere was ballasted so that it would remain upright even in a heavy sea, and looks as though it could carry 10 or 15 people. It came complete with mast and flag, and a wrap-around walkway, and as you can see it is being used in the image by a man having a smoke.
The "Lost" sign seems to be a little redundant.
