A New or Improved Fastener for Letter File:.
I, SAMUEL MAIER, Merchant, of 2, Bradford Avenue, Redcross Street, E.C., 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 an improved fastening for letter files of the type set
forth in my Patent No. 158 of 1897, and its object is to prevent the securing device
becoming detached.
In files of the before mentioned type, provided with bolt fastenings as hitherto
constructed, the bolt is liable to slip out of the socket or eye formed to receive it
when the file is tilted or reversed.
The arrangement I provide entirely prevents this happening. The eye formed
to receive the bolt is made by bending over a small extension on a plate, the plate
being riveted to the back of the file. A second projecting portion of this plate
at the side of the eye and a slight distance from it, is bent slightly forward so as
to project from the face of the plate. This projecting part is thus placed in front
of the eye and the bolt. or pin used to secure the fastening is prevented from coming
out until the movable part of the file is raised so that the pin can pass behind the
stop
In order that the invention may be more clearly understood, reference is had to
the accompanying sheet of drawings in which Fig. 1 is a perspective view of my
improved device applied to the file, Fig. 2 is a side view of the same, and Fig. 3
is a front view.
A is a small plate fixed to the back B of the file by riveting or other means.
This plate is formed with the projecting part a which is bent round so as to form
an eye. This eye receives the bolt or pin C which as shown consists of a bent wire,
one end of which is coiled around the movable part D of the file. The plate A is
also furnished with the projection or extension a² at one end. This is bent out
so as to extend in front of the eye as shown in Fig. 2 leaving room enough behind
it for the pin or bolt C to be withdrawn and replaced.
To withdraw this bolt or insert it in place the movable part D must be raised
allowing the bolt to be slidden behind the stop al and into or out of the eye.
When in the position shown the bolt is prevented from coming out of the eye as
it will abut against the stop.
There is thus no danger of the parts becoming detached while the cover is
closed, as the cover must be open to raise the movable pin.
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:
(1) In a fastening for letter files, the combination with a sliding bolt or pin,
of an eye carried by the back of the file and a stop in front of the said eye prevent-
ing the bolt being withdrawn when in ordinary position, but allowing it to pass
behind it when raised, substantially as described and for the purposes specified.

page_text: (2) In an improved fastening for files, the combination with a sliding pin or
bolt, of a plate secured to the back of the file, an eye formed at the top of the said
plate, and a stop in front of the said eye formed by bending an extension on the
piate allowing the bolt to be withdrawn only when raised, substantially as and for
the purposes specified.
(3) The improved fastening for letter files, consisting of a plate secured to the
back of the file an eye on the said plate, a stop formed by an extension on the
plate and a sliding pin or bolt, substantially as described and shown in the accom-
panying drawings, and for the purposes specified.
