My Franklin 1911 is hinged at the rear like a Singer, but it raises and lowers as the cover lid is opened and closed. There is a chain attached to the lid that actuates the lifter parts.
I've seen pics of one where the machine is hinged on the right side and pivots from there as the lid is opened and closed, and I've seen pics of one that pops straight up when you open the lid. The text said if you leaning over it when it came up you could be hurt.
Those I've not seen in person yet.
