Specification Accepted, 5th Feb., 1889
I, JAMES WEBSTER, of Fern House, Solihull Lodge, Holly Wood, near Birmingham,
in the County of Warwick, Engineer, 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 :-
My invention relates to improvements in that class of bill-files-more particularly
to hanging files-according to the construction of which the filing wire is made
detachable from the bottom plate of the file, for the purpose of taking any particular
paper off the file; and consists in an improved simple and inexpensive device for
instantaneously detaching the wire from the bottom.
In order that my invention, and the means by which it is to be carried into practical
effect, may be thoroughly understood, I will now proceed to describe them in detail,
referring in so doing to the accompanying drawings, which are to be taken as part of
this specification and read therewith.
Fig. 1. is a sectional elevation of a bill file constructed according to my invention,
closed.
Fig. 2 is a sectional elevation corresponding with Fig. 1, but shewing how the
filing wire is released from the detent.
A is the detachable filing wire; and B, the tube to which is fixed the bottom
plate C
The tube B is continued below the bottom plate C, far enough to receive the pointed
end a of the filing wire and the annular groove b formed in the said wire above the
end. The bottom of the tube B is advantageously closed by the stop bl.
The handle D is fixed to only one side of the tube B, at a point beneath the
plate C.
It is continued round to the opposite side of the tube and terminates in a nose c.
This handle is made of steel, or other resilient wire, and, preferably, has a ring el
formed in it, by bending it, which ring has the effect of imparting additional resilience
to the handle, thereby enabling it to discharge the function of a spring the action of
which will keep the nose c engaged in the groove b of the filing wire.

page_text: I form a notch 62 in the side of the tube B, through which the nose c enters to
engage with the said groove.
E is a thumb-plate depending from the bottom plate C. It has a notch cut in its.
bottom edge, whereby it embraces the adjacent part of the spring-handle D and serves
as a guide for it.
To detach the filing wire from the bottom, the fingers are passed within the spring-
handle or handle and ring, and the thumb placed upon the thumb piece E as illustrated
in Fig. 2. The thumb pushes the filing wire A from the nose c, and the fingers draw
the latter away from the wire, which can then be drawn out of the tube. As soon as
the handle-spring and thumb piece are released, the nose e re-enters the groove b.
The filing wire is re-engaged with the bottom by pushing its end past the nose c
which will be forced to engage therewith by the spring-handle D.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
The combination of thumb-piece, spring handle, nose, groove, filing wire and tube,
as set forth.
