3 Claims. (Cl. 129-23)
This invention is directed to a novel binder which may
be used to hold loose-leaf ?ller sheets in assembled super 10
posed relationship during use. In particular, the inven
tion is concerned with a binder wherein a writing instru
ment, either pencil, pen or other means, may be carried
in the binder without danger of loss and wherein the
closure means for locking the loose-leaf sheets in the 15
binder also serves the function of retaining the particular
writing instrument, whatever it may be, emplaced within
The elongated well 13'is bounded at the upper mar'—
ginal edge of base 1 by a vertical wall 15 formed, as is
well 13 integrally with the base. Wall 15, however, is
somewhat reduced in thickness such as to be laterally
yieldable. In other words, wall 15 may be ?exed slightly
from a true vertical position and will, because of the
limited resilience of the material from which it is formed,
have a pronounced tendency to spring back to a vertical
position.

Asmay be seen in FIGS. 1 and 2, the base 1 is also
provided with a pair of upstanding pins 17 and 19. These
pins are arranged in spaced vertically co-planar relation
on base 1 and are adapted to be engaged by the men
