means OF two conveniently located
levers and clutches II is possible to
quickly change from one dgiYe ~ one
speed 10 another. The drive is 50 con-

the car movement does not reverse
the direction OF chart travel. The
records are aiado on n chart 10 inches
vide, which is drawn ovef the table
between two sear-connectei rollers BY
means OF friction. Both originating
rpii and receiving roll are located At
tie back of the machine where they
can be readily removed or put in
place
All curves are drawn by pens at
tached to hollow aluminium rods run
ming az right angles to the paper All
datum line pens are connected 20 q
single cross bar az the front, their
records being made an inch In front
OF those made by the recording pens.
The pens are made of small brass
cups with phosphor bronze troughs
which carry a thread wick from tho
barrel TO the point; they will draw
line moving sidewise as well as for
ward.
The pressures from the dynamOmet-
er are transmitted 10 standard outside

indicator springs for the various
classes of work. The curve Of speed
