‘ McBee Company, Athens, Ohio, a corporation
of Ohio
Application June 4, 1935, Serial No. 24,796
r
3 Claims.
My invention, relates to that class of ‘boards’
which are described in my copending application,
Serial No. 709,731 ?led February 5, ,1934,v now
Patent No. 2,011,625, August 20, 1935. As de

scribed in that application, automatic means are
provided for shifting the spacer which carries the
' strip of paper or a line guide such as shown in
Patent No. 1,372,360 March'22, 1921; this op
eration being brought-about by the movement of
a plate, one side of which is hinged'to the platen
and when it presses down upon the platen it
holdsthe slip of paper which is to be written
upon and which is attached to the spacer in place.v
Upon this release the spacer is automatically
15 ,
shifted one line or more as desired.
I have found ‘
in practice that if the operator turns away from
the board before completing his entry on the slip
of paper the plate is ‘automatically elevated and
this in turn ‘permits the automatic mechanism to
20 shift the line‘sp'acer.

As shown in the drawings. the platen or writing
board I may be formed of any suitable material.
I prefer the use of a light metal such as aluminum
rather than of making it of wood. or any of the 20
heavier metals. In order to facilitate the placing
an improvement on {that board‘ by providing ~ of the master sheets on the platen, I provide a
means to lock the plate in position “so, that"v i‘tlwill:

will prevent the operation of the automatic

A further object is to provide aligning means

columns on the master sheet and if this should
occur it is possible for the numerals, entered in
the space in the columns, to be out of alinement.
I overcome this by de?ning the columns on the
entry strips as clearly seen in Fig. 9 from which
it will be apparent, that for example the space
on the entry strip in the vertical column 40 will
be narrower than the space 4| in the vertical col

by printing a plurality of vertical lines 42, 43 and
44. The result of this is that any irregularity in
