Today in 1906, US Patent 834491 A was issued, an invention of John P. Reily, for his “Hinge For Beer-Cases.” There’s no Abstract, although in the description it includes this summary:

This invention consists of certain new and useful Improvements in Hinges for Beer-Cases, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

The object of my invention is to provide a simple and inexpensive hinge which is particularly adapted for all manner of boxes, trunks, and chests wherein the lids swing entirely over against and into a plane parallel with the wall of the box to which the hinge is fixed.

By my improved construction of hinges the lids to which they are fixed can be swung all the way back without pulling out the retaining-screws of the hinges or breaking the lids.
