, The carriage H] has supported for limited slid
ing movement, lengthwise and rightwardly of the
carriage, on brackets 31, a carriage return rack
'38. This rack is slidable on the carriage against
the tension of a spring, not shown, and is opera
tively connected to a line-spacing mechanism for
the platen 3|, in a manner well known, and so
that an initial movement of the rack in the re
turn direction of the carriage will operate said
line~spacing mechanism, the latter acting upon
a ratchet wheel which is ?xed on the platen shaft
30 and which is indicated in Figure l by the ref
erence numeral 40.

,As is usual in typewriting machines, the car

from right to left, by a carriage feed band under
the influence of a spring drum 22. However, the
