John Whines Double Action Box Spring Hinge

Today I would like to introduce readers to John Whimes of Pimlico and his Double Action Box Spring Hinge For Swing Doors.

According to Newton's London Journal of Arts and Sciences Volume 15 Mr Whimes was acknowledged for improvements to double action box springs for swing doors on the 8th of June 1861. Above is the print of his door spring taken from the same book and which can be found in the link below for those interested.
