20 Claims. (Cl. 197-133)
This invention relates to improvements in strip
feeding mechanism for feeding, controlling and
guiding the record strips in their passage over the
platen of writing machines or typewriters of the
5 type having paper or platen carriages which are
shiftable for letter spacing.
It is an object of the present invention to pro- I
characters refer to similar parts throughout the
several views :-

Another object is to provide an improved feed
ing means for machines of the class mentioned
and constructed as a unitary device readily at

Another object is to provide a comparatively
light weight improved feeding means which has
minimum tendency to disturb the proper balance
of the ‘carriage during‘ the shifting thereof, even
though located at one end only of the'carriage,
35 and which will not add unduly to the weight of
the carriage and so that movement of the latter
endwise and sudden stopping thereof may be ac-
complished without injuring the machine.
Another object is the provision of a simple and
