i1 Claims. (Cl. 197_63)
This invention relates to the art of typewriters or the
like, and more particularly to the margin setting mech
anism thereof.
It is among the objects of the invention to provide a
margin setting mechanism for typewriters or t-he like
employing movable carriages, which mechanism may
readily be incorporated in a conventional typewriter with
but little modification in the structure thereof, which has
but few parts which may readily be fabricated at low

ally inward therefrom at right angles thereto are brackets
31 and 32, each having a finger 33, 34 rising from its
upper edge.
Extending between the brackets 31, 32, as shown in
FIG. l, and secured at each end thereto as by screws 3S
is a flat margin rack 36, which is desirably rectangular
in cross section and has teeth 37 along its lower edge, the
margin rack 36 being positioned directly beneath the
root ends of fingers 33, 34.
The margin rack 36 serves as the mount for a pair
of margin setting members 41, 42. for the right and left
margin, respectively.
As the margin setting members are substantially iden
tical, only the former will be described in detail.
cost and which are not likely to become deranged even
Thus, the margin setting member 41 desirably has

two elements, i.e., a margin set top 43 and a margin set

sired positions with a relatively simple manipulation with
top 43 comprises a substantially rectangular plate 4S,
out likelihood of jamming of the margin set members,
and will provide a visible indication of the position of
the margin set member whether the latter is manually
having parallel ears 46 extending laterally outward there
or automatically moved.
According to the invention, these objects are accom
4from at right angles thereto. Each of the ears 46 has a
vertical slot 47 therein of a length greater than the height
of margin rack 36, and the thickness of the ears is such ~
that the lower edge of the slots 47 may enter the space
plished by the arrangement and combination of elements 25 between adjacent pairs of teeth on the margin rack 36

claims.

As shown in FIG. l, an abutment 80 extends inwardly
from each of the brackets 31, 32 in the path of move
ment of the free end of each of the release levers to
limit their downward movement.
Means are provided to restrain movement of the car
riage, based upon the position of the margin set members
41, 42 when the carriage is moved to the left or to the
right.
Due to `the fact that the margin set Vbottom 44 is re
strained from cocking by the fingers 57, 58, automatic
movement of the margin set members 41, 42 when the
fingers 75, 76 are pressed will occur without possibility
of jamming.

visible, the typist can accurately determine the location
of the margin, «even when the latter has been automatically
