Model printing press. "Excelsior" 1873. Made by Kelsey & Co, accompanied by a printing forme handset with monotype.
The empty frame is known as the chase. The chase filled with a job for printing is known as the forme.
The forme contains type and spacers (technically known as furniture). The type and spacers are held in place using screw clamps, which are part of the chase.
Setting type by hand is known as 'composing the type'. The type is taken letter by letter and placed into a 'setting stick' - a wood or metal tray held in one hand and the words are built into lines of type of a set width.
The lines are then put together to make a page inside the chase. Spaces in amongst the page are filled with wooden or metal "furniture". The furniture is level with the surfaces of the type blocks so as not to pick up any ink.
The forme is placed on the press, inked and printing commenced.
A model printing press complete with forme.
