tape, at least in part, so that the ?ngers of a
reader moving along the tape need follow only
this line to detect all of the symbols. The dan
ger of missing some of the symbols is thus
greatly reduced, and the ease and accuracy of
reading are increased.
‘In this respect, the invention contemplates the
use of two members arranged side by side in the
direction of movement of the tape, with a mech
anism for causing such members‘ to emboss the
successive symbols at proper intervals.
An additional object of the invention, in con
nection with such an embossing mechanism, is
the arrangement of the tape feeding mechanism ‘
in such a way as to clear the embossing at each
stroke of the machine, this being preferably ac
complished by arranging rollers on opposite side
of and above the embossing anvil.
The invention further includes a device for
reading a tape so printed. One object of this de
vice is to provide an audible tone of di?ering
sound for each type of symbol, so that the listener
can easily follow the message on the tape as it
is fed through.
A further object of this device is to prevent
the transmission of impulses to the sound emit
ting apparatus by creases or seams in the tape.
Still another object is to provide, in connec
tion with the type of tape described above, hav- '
ing parts of all symbols in the same line longi
tudinally of the tape, parts actuated‘ by projec
tions in different horizonta1 lines, one of which
is actuated by all the‘symbols and the other by
only one type of symbol; with such an arrange; 55

If a dot is to be formed, this'blank space is fed

and is then fed forward.

It will also be noted that the plane joining
the engaging points of the rollers which guide the
tape is located above the tops of the dies. When

not interfered with.
