a two-colour ribbon may be used, the second colour being
brought into use by pressing the small switch to be seen
just below fifty on the scale.
Three degrees of line spacing are provided for, and
variable spacing for permitting of writing on ruled lines
can also be effected. The line spacing is made by the same
movement as that which returns the carriage for a fresh
line.
What is regarded as a valuable feature of the present
machine is the ability to remove the platen in order to
replace it with another, such as a hard platen for use in
manifolding or mimeographic work.
As in the case of the Monarch, the depression of the
shift-key affects not the carriage or the platen, but the
type-basket, which is raised, and it is recommended to
lock the shift-key in order to raise the type-heads whenever
it becomes necessary to clean the type.
The escapement of the Smith Visible is rapid in the
extreme, the touch light and pleasant, and the machine

possible work being executed, with a minimum of wear
and tear upon the parts.
The Fox. In addition to the machine mentioned in
Chapter III., the Fox Typewriter Company have also

better than reproduce their whole argument in support
of the methods which they have adopted in arranging
the type-bar mechanism of the visible Fox.
“ Any expert typewriter mechanic,” says the Company,
“ will say, ‘ Show me the type-bar hanger and I will tell
you how long the typewriter will retain its alignment and
whether or not it will be durable.’ The type-bar is that
part of the typewriter that holds the type ; when a key
is depressed, it is the type-bar that swings upward and
biings the type to the printing surface. Consequently,
the bar must be strong and heavy, for it has many thousand
such operations in every day’s work.
“ The type-bar hanger holds the type-bar in position.
The point where the bar ‘ swings ’ in the hanger is the
* bearing point ’ and it is the wearing quality at this point
