COMPLETE SPECIFICATION.
Improvements in Temporary Binders.
I, FRANK DOUGLAS HUTCHINS of Norwich, County of Chenango, State of New
York, U.S.A., Inventor, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:
In the accompanying drawing Fig. 1 is a plan view of the temporary binding
cover of this invention with leaves secured therein. Fig. 2 is a perspective view
of the binder and its cover, the latter in the open position. Fig. 3 a plan view of
the mechanical parts of the binder in the closed position. Fig. 4 the same in the
fully open position. Fig. 5 the same in the partially open position and as seen
from the lower side of the device as shewn in Fig. 3. Fig. 6 a back view of the
parts shewn in Fig. 3 to 5 inclusive. Fig. 7 shews the blank out of which the body
portion of the binder is formed. Fig. 8 the blank out of which the hinged
fasteners, constituting a portion of the binder are formed. Figs. 9 and 10 shew
modified forms of construction.
The binder consists of a body 1 formed preferably of sheet metal and provided
with hook projections a, b, c, by means of which the body may be secured in the
cover 2, which latter may be of leather, book board or the like and the projec-
tions a, b, c, are preferably engaged between the layers of the cover. On the
back of the binder body 1 are hinged two binding or clamping pieces 3, 4, upon
the wire 5 so as to be capable of lateral movement. On the opposite side of the
body 1 from that to which the binding or clamping pieces 3, 4, are hinged, are
provided the posts 6, 7, also of sheet metal. A notch in the upper end of these
posts 6, 7, is adapted to receive the edge of the clamping pieces 3, 4, respectively,
at the slots & when said clamping pieces are turned down and slid laterally to one
side. Upon the under side of pieces 3, 4, is provided a spiral spring 8 operating to
force the pieces apart along the wire 5 and at the same time, when the clamping
pieces are closed, force the edge of each of the pieces, at the slots d into the notches
of the posts 6, 7. For retaining the spring 8 in position there are provided on
the underside of the clamping pieces 3, 4, a pair of overlapping arms 3º, 4ª,
passing through the spiral spring. Both these arms are alike except that the arm 4"
is provided with a lip or overlap to make the arms register and slide freely, upon
one another without catching in the spring. When the device is, or the clamping
pieces are, in the open position, a pad or a number of sheets of paper B having suit-
able perforations at one end, may be placed upon the posts 6, 7, and fastened down
by the clamping pieces in the manner described. The posts by passing through
the clamping pieces and being locked therein are securely braced at their upper
ends making the device as a whole capable of withstanding rough usage. The
sheets may be torn out of the binder or removed by reversing the process by which
they were placed therein.
In the modified construction shewn in Fig. 9, three posts 6ª, 7, and x are pro-
vided which adapt the binder for use with extra wide paper. In this case one of
the clamping pieces 31, 4', has two slots for the reception of two of the posts. Of
course any other desirable number of posts may be used with a corresponding
number of slots in the clamping pieces.

page_text: In Fig. 10 the clamping pieces are shewn with over-lapping projections so that
when one is raised or depressed it carries the other with it.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. The combination in a temporary binder of a body, a clamping plate hinged
to and longitudinally movable with reference to the body, and a notched post with
which the clamping plate engages, substantially as described and shewn.
2. The combination in a temporary binder, of a body, a clamping plate hinged
to and longitudinally movable with reference to the body, a post on the body,
and a spring for moving the clamping plate and holding it engaged with the post,
substantially as described and shewn.
3. The combination in a temporary binder of a body having projections for
attaching a cover, binding posts, clamping plates hinged to and longitudinally
movable with reference to the body, and a spring acting between the clamping
plates to hold them apart and in engagement with the binding posts, substantially
as described and shewn.
