PROVISIONAL SPECIFICATION.
Improvements in Files or Binders for Holding Letters, Bills, and
other Papers and Documents.
I, ARCHIBALD DONALDSON of No. 20 Bridge Street Hawick Roxburghshire
Scotland, Traveller, and I, GEORGE DONALDSON of No. 27 Pratt Street Lambeth London
Surrey England do hereby declare the nature of this invention to be as follows :--
This invention relates to a file or binder, adapted to conveniently receive letters and
other papers and to permit of the removal of any one of their number after filing, or
the insertion of a paper among or between those already filed, without removing or
deranging the latter. The said invention consists in combining with a file or binder
already in existance, a hinge connecting the movable to the fixed portion of the binder
instead of having them unconnected as at present.
The file or binder may be described as follows.
It consists in combining with, a suitable base a fixed straight receiving tube and a
movable transfer wire the latter being U shaped, one of the straight portions of it
sliding on the tube the other being fixed temporarily to the base when file or binder is
closed and disconnected with it when open.
The construction and arrangement above described afford a continuous arch adapted
to be opened for the insertion of a paper on the fixed tube and to be closed to retain
the same on the file, and also to permit a paper to be transferred to the movable wire
to allow of the removal of an underlying paper if desired. The said file or binder
also consists in arranging a number of such tubes upon a common base and in parallel
planes, vertical to the base, so that a paper may be transferred to the two movable
wires without enlarging the punctures in the sheet.
The said file or binder also consists in connecting the movable wires together at the
ends of the wires opposite the fixed receiving tubes, so that when one of the wires is
moved the others are also moved.
The said invention consists in connecting the movable wire or wires with the base
by a hinge so that the wires may be pulled up out of the tubes and moved backwards
from the tubes for the purpose of inserting a paper on or removing a paper from the
file and so that the movable wires may be the more readily brought back and inserted
in the tubes in the operation of closing the file or binder.

I, ARCHIBALD DONALDSON of No. 20 Bridge Street Hawick Roxburghshire
Traveller and 1 GEORGE DONALDSON of No. 27 Pratt Street Lambeth London
Surrey 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 :-
This invention relates to files of the class described in the Specification of Letters
Patent dated July 29 A.D. 1879 No. 3075 and Letters Patent dated Feby. A.D. 1884
No. 4159 and comprises improvements as hereinafter described.
In the accompanying drawing

page_text: The same letters refer to the same parts in both figures.
According to this invention we fix on a metal plate (A) small tubes (B. B.) into
which the ends of the wire (CC) slide when file is closed.
The wire (CC) is also connected with the metal plate (A) by means of the parallel
hinge (D. F. G.) consisting of
Da flat metal tube with a wood core or centre Ę.
F. a piece of wire bent in the form of a rectangle.
G. a semicircular flap forming a portion of or fixed to (A).
The construction and arrangement above described afford a continuous arch, adapted
to be opened for the insertion of a paper on the tubes and to be closed to retain the
same on the file, and to permit a paper or papers to be transferred to the movable
wire to allow of the insertion or removal of an underlying paper or papers if
desired.
It is convenient to have one of the ends of the wire (U. C.) shorter than the other
so as to allow of easy entrance into the tubes for which purpose the ends may also be
pointed.
The metal plate A may be fixed to any suitable base by means of screws, rivets, or
any other convenient manner.
It will be easily understood that the parallel hinge may be constructed in a variety
of ways, but the one hereinbefore described is at once simple and efficient.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what wo
claim is
The application of the parallel hinge as hereinbefore described to the file described
in Letters Patent dated A:D. 1884, 29 Feby. No. 4159.
