This invention relates to a carrying case for
portable typewriters.
(01. 45-682)
_
.
One of the objects of this invention is to pro

and thoroughly durable. Another object is~to
provide a case of the above character which may
which may be used with any make of portable
typewriter and is provided with mechanism to se
curely connect any. typewriter to the case after
making one simple adjustment-in the connecting
mechanism, as will be pointed out'hereinafter.
In general, the metal connecting mechanism in
cludes a clamping plate, generally indicated at
I2, which may be moved toward and from the
front wall 14 of the base 10 of the case by moving

‘ ers. Another object is to provide a case of the
above character 3to which a portable typewriter 15 5, the typewriter is clamped between clamping
plate [2 (Figure l) and the rear surface of plate
may be easily and quickly connected or detached.

This typewriter case. is of a. universal type
is made, the under surface of link 24 has trans
verse teeth 42 (Figure 10) formed thereon which
engage transverse teeth 44 on theforward end of

portion I2a of clamping plate I2. A screw 46
passing through slot 26 and threading into por
tion l2a (Figure 2) acts through its head to
clamp link 24 to portion I2a and thus hold teeth
42 in engagement with teeth 44.. When it is
desired to adjust link 24 with respect to clamp
ing plate I2, screw I2a is loosened, teeth 42 and.
44 become disengaged, and at this time clamping
plate I2 may be moved toward. or from link 25..
When clamping plate I2 is properly positioned, 10

member 50 to the right, as viewed in Figure 4.
As pointed out hereinabove, tongue I6a of
lever I6 prevents the front end of the typewriter
from movingupwardly with respectvv to base II)
when the typewriter is locked to base I0.
To
accomplish this, tongue ISa is pressed down
wardly into engagement with the upper surface of
the forward portion of the frame of a typewriter
diagrammatically indicated by the dotted lines
86 (Figure I1‘). To hold lever I6 in a locked
screw 46 is tightened, and from then on, clamp
position, it is provided with a detent 82 (Figures

'7 and 11) which 'coacts with teeth 84 formed on
portion of link 24.
and; extending forwardly from one edge of a
Movement of clamping plate I2 toward and
from front wall I4 is controlled by lever I6 (Fig 15 recess 86 formed in plate 58 (Figures 4 and 11).

ward end in engagement with plate 58. Plate I2
is then moved’ forwardly until pad 90 is spaced a
slight: distance from the rear surface of the type
writer’s framework. The typewriter is then re
moved and screw 46. tightened. At the time this
adjustment is made, handle I6 is in a raised po
sition, as shown inFigures 1 and 4.
.
Next, the typewriter is placed in the case with
its forward end abutting against plate 5.8 (Figure
in a vertical plane as. it- moves longitudinally of
plate 58. Member 56 rests upon bottom 32 and

angularly positioned with respect. to wall Hi to
form a. cam surface so that. when, member 5.!) is
moved; upwardly; as viewed. in Figure 2, it en
gages a lug: 2m extending upwardly from the
forward end of‘ link 2%. and moves link 25,, and
thus. plate I52, away from wall Ill. as viewed in
Figure 2. Member 53 also includes, an angularly
shaped portion 596 which forms a. cam. surface 63
and presses it tightly against. plate 58. Because
.of pad 90, the rear portion of the typewriter is
securely connected togbasev I6, and the forward
portion of the typewriter is held in position by
tongue I60. of lever It. When itis desired to re
move the typewriter from the. case, the user
presses forwardly on‘ ?ngerpiece IBb (Figures 7
and 11) to disengage detent 8.2v from teeth _'84.
Lever I6 may then be raised from the position it
