Engineer do hereby declare the nature of this invention (a communication from
George Henry Richter of the City of Toronto, Canada, Gentleman) to be as
follows:-
This invention relates to an improved device for simultaneously locking or
unlocking all the paper-files within a single cabinet'; and it consists essentially of
a bar arranged behind each row of files within the cabinet, and having hooks'
attached to it designed to fit into a hole made in each file, all the bars so provided
being connected together by a cross-bar actuated by a spring designed to hold the
hooks away from the files except when acted upon by a spindle having a crank on
its inner end to connect with a crank pivoted on the cross-bar or one of the hook
bars, the said spindle extending to the front surface of the cabinet where it is
provided with a bandle and lock.

I ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Engineer do hereby declare the nature of the invention (a communication from
George Henry Richter of the City of Toronto, Canada, Gentleman) 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 device for simultaneously locking or
unlocking all the paper files drawers or the like within a single cabinet; and it
consists essentially of: a bar arranged behind each row of files within the cabinet
and having hooks attached to it designed to fit into a hole made in each file, all the
bars so provided being connected together by a cross bar actuated by a spring
designed to hold the hooks away from the files except when acted upon by a
spindle having a crank on its inner end to connect with a crank pivoted on the
cross bar or one of the hook bars the said spindle extending to the front surface of
the cabinet where it is provided with a handle and lock arranged substantially as
hereinafter more particularly explained.
In the accompanying drawings:
Figure 1 represents a perspective view of a file cabinet showing a portion
broken away to exhibit this improved locking device.
Figure 2 is a perspective detail of the bars and spindle constituting the improved
locking device.
Figure 3 is an enlarged detail showing the discs.
Figures 4 and 5 are alternative forms for locking the files.
Figure 6 is an alternative form of crank connection between spindle and bars.
A represents an ordinary file cabinet containing the paper-files B..
Upon the inside of the back of the cabinet A and behind each row of files-B
I place a bar C secured to the back or frame of the cabinet by screws D which
pass through slots in the bar C so that while holding the said .bar against the back
of the cabinet A they permit a free vertical movement of the said bar.
At each file B I attach to the bar C a hook E designed to fit into a hole F made
in each file B as indicated.
G is a cross-bar arranged to connect together all the bars C. A spring His
placed below the bar G or elsewhere but so that it and all the bars C connected to
it are held up by the action of the said spring H to keep the hooks E out of the
holes F.
I is a spindle suitably journalled in the cabinet A and having formed or attached
to its inner end a crank J which connects with the link K pivoted upon one of the
bars C as indicated or if preferred this link might be pivoted upon the cross-bar G.
A handle L is formed on the outside end of the spindle I so that the said spindle
may readily be turned from the outside of the cabinet in order to draw the bar C
down and thus force the hooks E into their respective holes F made in the files B
as before described.
M is a lock preferably provided with a spring bolt N so that when the notch C
in the disc P which is attached to the spindle I is brought next to the spring-bolt N

page_text: the said spring-bolt is forced by the action of its spring into the said notch, thereby
locking the files as the notch O is at such a position in the disc P that when it is
brought into connection with the spring-bolt N all the hooks E are held down into
their respective holes. In order to unlock the files it is merely necessary to draw
the bolt N back by its key when by the action of the spring H all the hooks E are
forced up out of their places and the files are thus released.
Instead of making a hole F in the file B a lug or projection f such as is shown
in Figure 4 might be substituted or the same effect might also be secured by
forming a pin on the file and a projection on the bar C with a hole in it to slip
over the pin as shown in Figure 5. I therefore consider all of these as equivalents
for one another.
Instead of employing the crank J and link K for connecting the bars to the
spindle I sometimes use a wiper Q as shown in. Figure 6 attached to the spindle I
and acting on the pin or projection R on the bar C.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is:
1. In an apparatus such as described the combination with the spindle I and
notched disc P carried thereby of a lock such as M having a spring bolt designed
to engage with the notch in the disc P when said notch and spring bolt are
coincident substantially as and for the purpose specified.
•
2. In an apparatus such as described a series of bars such as C set within a
cabinet behind the rows of files and provided with a hook such as E for each
respective file a cross bar G for connecting together the bars C and means for
connecting the said bars C to the spindle I in combination with a spring and lock
such as H and M the whole constructed and operating substantially as and for the
purpose specified.
3. The complete device for locking files drawers or the like substantially as
specified.
