PROVISIONAL SPECIFICATION.
An Improved File or Binder for Letters, Bills, and the like.
I, ARCHIBALD DONALDSON, and I, GEORGE DONALDSON, both of the firm of
A. & G. Donaldson of No. 20 Bridge Street Hawick, Roxburghshire Scotland,
Manufacturers and Agents do hereby declare the nature of this invention to be as
follows:-
According to this invention two tubes hereinafter to be called the receiving tubes,
parallel to each other and connected at their lower ends by means of a wire are hinged
to a suitable base by passing the before mentioned connecting wire through a tube or
under a flap fixed to the base. Second, connected together and hinged to the base in
the same manner as the receiving tubes are two arched wires whose free ends enter
the upper ends of the receiving tubes and which move in the same plane as the
receiving tubes, and are such a distance apart that a paper may be transferred from
the receiving tubes to the transfer wires without enlarging the punctures in the
sheet.
The construction and arrangement above described afford a continuous arch adapted
to be opened for the insertion or removal of a paper or papers on the tubes and to be
closed to retain the same on the file and also to permit a paper or papers to be
transferred to the transfer wires to admit of the insertion or removal of an underlying
paper or papers if desired. Third fixed to the common base is a movable catch to
prevent the transfer wires moving away from the movable tubes when the papers are
being turned over and when the file is not in use.

COMPLETE SPECIFICATION.
An Improved File or Binder for Letters, Bills, and the like.
I, ARCHIBALD DONALDSON and I GEORGE DONALDSON both of the firm of
A. and G. Donaldson of No. 20 Bridge Street Hawick Roxburghshire Scotland
Manufacturers and Agents do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
In the accompanying drawing Fig. I is a perspective view of improved File closed.
Fig. II is a perspective view of improved File open.
The same letters refer to the same parts in both figures.
A A are two movable receiving tubes running parallel to each other and connected
together at their lower ends by being soldered on a wire which passes up the inside of
the tubes and also passes through the flap or tube C.
BB are two arched wires or one wire bent so as to form two arches parallel to
each other and having one side of the arches sliding in the movable receiving
tubes A A and being connected together at the other side of the arch by the wire
passing through the tube or flap D.
C and D are two tubes or flaps made of a plate of metal by being pressed round the
wire connecting the tubes A A together and the wire connecting the arches BB
together the whole forming a base plate which can be fixed to any suitable base by
screws rivets or other suitable means.
E is another tube or flap soldered to the base and forming a slide in which Fa
movable catch slides lengthwise. The tubes A A and the wires B Bare movable in the

page_text: planes formed by the arched wires in such a manner that a paper may be transferred
from the tubes to the wires without enlarging the punctures in the sheet.
F F is a catchwire or bolt sliding in the tube or flap E in the direction of the
length of the tube and bent in such a manner that one end of the wire FF passes
behind one of the arched wires B B and prevents the file from opening as shewn in
Fig. I. The other end of the catchwire F F is bent to form a handle to allow of its
being easier pulled through the tube E away from the arched wire B so as to allow
the file to be opened as shewn in Fig. II.
The file or binder is opened by moving the tubes bodily backward when the ends
of the transfer wires are removed from the tubes and allow papers to be inserted and
removed from the file.
The file or binder may consist of any number of such sets of tubes and wirez
preferably two. It is convenient to have one of the ends of the transfer wire a little
longer than the other so as to allow of the easy entrance into the tubes A. A for which
purpose the ends may also be pointed.
The construction and arrangement above described afford a continuous arch adapted
to be opened to allow of the insertion or removal of a paper on the file and to permit
of a paper or papers being transferred to the arched or transfer wires to allow of the
insertion or removal of an underlying paper if desired.
We do not confine ourselves to the particular construction of the individual parts
as they may be easily varied as example the catch wire F may be done away with
and the file used without any catch whatever or the ends of the arched wires may be
slightly bent or roughened so as to catch in the tubes and prevent the file from
opening too easily.
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 we
claim is
The adoption of the peculiar motion of the parts as hereinbefore described.
