C. Spiro, which is known as the Bar-Lock, and which was
described at length in Chapter IV. The Columbia was
introduced in 1885, and has taken a number of medals for
general portability and adaptability. It was made in
two styles, the No. 1 having forty-four characters and
writing capital letters and figures only, the No. 2 having
seventy-two characters, including upper and lower case
letters, numerals, etc. It consists of a wooden base nine
inches long, three and a half inches wide, and the height
of the machine is about seven inches. Mounted on a
suitable standard are two wheels, one of which is perpendi-
cular, and the other horizontal. The two are connected
by cogged teeth.
The perpendicular wheel carries the type on its periphery,
and is revolved by means of a knob until an index hand
on the face of the horizontal wheel points to the letter it
is desired to print. A downward pressure on the knob causes
the impression to be effected. The Columbia gives a
differential or “ proportionate ” spacing, and prints direct
from the type, which derives the ink from a small moving
ink pad. The Columbia is undoubtedly the best of this
class of index machines.
The Champion. The Champion is a “ pointer ”
machine. Its general appearance is not unlike the
Hammond on a small scale. It has a type-wheel in a
horizontal plane, by the rotation of which the characters
are brought to the printing point. The rotation is effected
by the movement of a pointer by the forefinger of the right
hand over an index plate. When the pointer is over the
desired character, a thumb lever is pressed, and the paper
thus brought into contact with the type. A ribbon is
the inking device, in which the Champion differs from most
pointer machines. It is said that forty wards per minute-
have been written with it.
