It is known that typewriters or calculating
machines comprising a platen are not, suitable
for bookkeeping work. In fact, for such oper
ations it is necessary tointroduce on the platen,
and over the ?rst sheet of paper constituting the
journal sheet, several additional independent
sheets.
The last line of writing on these addi
tional sheets must be written to register with
the last line of writing on the sheet carried next
to ‘the platen, which,‘ is generally the journal
sheet.

writer to free the journal sheet engaged on the
platen and to slide along the invoice form or

the action of a spring, and‘ ‘at ‘the other end ‘to
a manipulating drum which is subjected, to the
action ‘oflan escapement device, the crossbars
being adapted for holdingv the sheets ‘by their
balance sheet which is above the journal sheet,

correctly. This work is very difficult to do and
also tedious, and besides that the carbon paper

Referring to the drawings, in Fig. 5, the‘mov

to introduce a second additional independent
