Building Second Floor Experimental Rooms
In November 1887, Charles Batchelor noted his diary that the "small rooms"
were finished the laboratory except for the locks the doors. These rooms
-their equipment, their location, and their proximity the precision machine
shop-are the embodiment Edison’s method inventing.

line experimental rooms took the south side the space. The inventor believed that the patent system
could not fully protect his work and subsequently carried out experiments in
highly competitive areas, such electric lighting and motion pictures, an

The rooms were numbered one through nine the south side and ten through
twelve the north.
The experimental rooms ran along both sides central hallway the second
floor. Each room housed a

command higher wages than the average machinist. the south side the rooms ran the length the floor and overlooked
