of various sizes and cross sectional formations.
Another important object of the invention is to

Still another important object of the invention
is to provide a pen holder which will not only

These and various other important objects and
advantages of the invention will become apparent

Now referring to the slidable sleeve ll, it can
be seen that this sleeve is provided with a pocket
like construction I8 at its inner end, the forward
edge portion of which is disposed and formed to
deñne a cam surface I9 for riding engagement
with vthe pin 1. Obviously when this sleeve I'I is
rotated toward the right (see Figure 2) the cam l5

cooperation of the brace formation I6 will firmly
clamp the pen point against the core member I2.
Figure 3 is an enlarged end elevational view of
the holder.
30 Figure 4 is a longitudinal sectional View through
the sleeve.
Referring to the drawing wherein like numerals
designate like parts, it can be seen that numeral
5 denotes the usual shank of the holder which in
35 the present instance is reduced at one end por
tion to accommodate the ferrule 6 from which
projects the pin 1.

'I‘his end portion of the shank 5 is provided
with a longitudinally extending opening axially
40 disposed, for receiving the shank portions 8 and
9 of the spring fingers I0 and I I, respectively, as
Well as the inner end portion of the elongated
core member I2, which core member is preferably
of polygonal cross-sectional shape.
As is clearly shown in Figure 1, the outer end
portion of the core member I2 is interposed be
tween the fingers IO-II and at its extremity is
beveled as at I3.
The finger I0 is provided with the laterally di
50 verged portion a merging with the inwardly dis
posed T-formation b.
The outer end of the finger I I is diverged lat
erally as at c and is provided with the inwardly
disposed and transversely extending arcuate
55 shaped yoke I4.

It will be observed, that the yoke I4 with the 25
At the same time the T-shaped formation rein

deformation thereof.

The sleeve I‘I may be provided with the usual
cork or other suitable covering.
While the foregoing specification sets forth the
invention in specific terms, it is to be understood 5
that numerous changes in the shape, size and
materials may be resorted to without departing
from the spirit and scope of the invention as
claimed hereinafter.
Having described the invention what is claimed 40
