Set of 10 Specifications of Letters Patent 1855-1917 from Washington DC Lawyer

Description

HERE WE HAVE A SET OF 10 ITEMS LABELLED "SPECIFICATIONS OF LETTERS PATENT", WHICH APPARENTLY DATE FROM 1855-1917. THEY APPEAR TO BE TO BE ORIGINAL, AND I'M GUESSING WERE COPIES GIVEN TO THE ATTORNEY FOR HIS FILES, A FELLOW NAMED WATSON E. COLEMAN, WHO WAS A PATENT ATTORNEY IN WASHINGTON, D.C.. HIS NAME AND ADDRESS ARE STAMPED IN RUBBER STAMP ON THE FRONT COVER OF EACH ITEM. IN THE GROUP ARE THE FOLLOWING PATENTS:
OSCILLATING VALVES AND GEARING FOR PUMPING ENGINES. . .1855
RELEASING VALVE GEAR. . .1888
CUT OFF VALVE GEAR. . .1889
VALVE GEAR FOR STEAM ENGINES. . .1892

EACH OF THEM MEASURES APPROX. 8 X 11 1/2 INCHES, AND THERE ARE VARYING DEGREES OF CONDITION, AS I'VE DESCRIBED ABOVE AND YOU CAN SEE IN THE PHOTOS. I DON'T KNOW MORE THAN THAT, THESE WERE IN A MASS OF OLD PAPER AND EPHEMERA I ACQUIRED A FEW YEARS AGO. I RAN ACROSS THEM THE OTHER DAY AND THOUGHT I'D SEE WHAT THE INTEREST IN THEM WAS. THE RENDERINGS ARE VERY COOL, IF NOTHING ELSE WOULD MAKE NEAT DECOR PIECES. THEY MAY ALSO HOLD SOME HISTORICAL VALUE, I JUST DON'T KNOW. PLEASE EXAMINE THE PHOTOS CAREFULLY FOR YOURSELF.
