Improvements relating to Inkstands or like Receptacles.
1 JAMES STEVENSON of Grays Inn Chambers, 20 High Holborn London W.C. in
the County of Middlesex, Civil Engineer and Patent Agent, do hereby declare the
nature of this invention to be as follows
My Invention is devised with a view to ensure that Inkstands or receptacles
provided with lids shall become automatically closed when not in use, and thus to
avoid the waste and deterioration of the ink, which occurs from neglect to close said
lids or covers.
According to my Invention, I cause the lid or cover of an inkholder to be lowered
into its place and close the opening of the ink bottle or receptacle by the mere
placing the penholder on the curved ends (serving as a pen rack) of a double, pivoted
lever, which latter is also connected by an arrangement of articulated members with,
the hinged cover of the ink holder. Now, on the removal of the penholder from the
rack which contains it, a small counterweight in connection with the articulated
arrangement of levers aforesaid causes the lid or cover to be raised and allows of.
access to be had to the contents of the ink-bottle. Then, on replacing the penholder
in its containing rack, the weight of same causes the lid or cover to descend and
close the aperture of the ink-holder as before mentioned.

COMPLETE SPECIFICATION.
Improvements relating to Inkstands or like Receptacles.
I, JAMES STEVENSON of Grays Inn Chambers, 20 High Holborn London W.C. in
the County of Middlesex Civil Engineer and Patent Agent, 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 is devised with a view to ensure that the lids or covers of inkholders,
or bottles of inkstands shall become automatically closed when not in use, and thus
to avoid the waste and deterioration of the ink which occurs from neglect to close said
lids or covers.
According to my Invention I cause the lid or cover of an inkholder' to be lowered
into its place and close the opening to the inkbottle or receptacle by the mere
placing the penholder or the like on the curved ends (serving as pen rack) of a
double, pivoted lever, which latter is also connected by an arrangement of articulated
members with the hinged cover of the inkholder. Now, on lifting the, penholder
from the rack which contains it, a small counterweight in connection with the
articulated arrangement of levers aforesaid causes the lid or cover to be raised and
allows of access to be had to the contents of the ink bottle; whereas, on replacing
the penholder or the like in its containing rack the weight of same causes the lid
or cover to descend and close the aperture of the ink bottle as before mentioned.
In order that my Invention may be the more readily understood I have appended
the accompanying sheet of drawings in which Figure 1 is a plan view and Figure 2
an end elevational view partly in section of the device according to my Invention ; a
slightly modified arrangement of which is shown in the plan view Figure 3 and

page_text: sectional elevation view Figure 4. Like or corresponding letters of reference being
employed to denote the same or corresponding parts throughout the Figures;
referring to which, A, B, B, A, is the double, pivoted lever above referred to, mounted
upon the two. supports or axes S S. The two arms A, A, of the lever A, B, B, A, are
formed at their extremities so as to allow of their receiving the penholder or the
like P. The lid C which turns around its fixed axis H is also so disposed that when
it is lowered it covers exactly the top of the inkholder N. The lid C is provided
with an arm D. A connecting rod or link G is jointed at one end with the arm D
and at the other end, at E, with the centre of the rear portion B, B, of the double
lever A, B, B, A-A counterbalance is likewise adapted to this latter part of the
double lever. The weight of the counterbalance is so determined as to ensure the
lid C being entirely free or relieved from the mouth of the inkholder N when
the penholder, or the like, P is not in position on the ends of the arms A A. The
cover C will then assume the position shown in full lines at C Figure 4 and in dotted
lines (Figure 2, whereas, when the penholder, or the like, P, is in position on the
curved ends of the arms A A, the weight of P suffices, through the articulated
arrangement of parts above described and shown in the drawings, to bring the lid C
down, over upon, and thus to automatically close, the mouth of the inkholder N. I
wish it to be understood that although in the drawings I have only shown an ink-
stand with one inkholder, my Invention is applicable to inkstands with any number
of inkholders. Neither do I confine myself to any particular description or type
of inkstand, as the latter will in practice be determined upon in view of the
intended use, whether for instance for commercial, or for private uses, (thus in
Figures 3 and 4 the base of the inkstand is shown of an escalloped configuration).
Nor do I consequently confine myself to the exact details of the lever and counter-
balancing devices described and shown as these will necessarily may vary to be in
accord with the general design of the inkstand having my improvements.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed I declare that what
I claim is-
First In an inkstand having one or more inkholders the means which I employ
substantially as herein set forth whereby I am enabled to ensure that under the
condition obtaining when no penholder or the like is in position on the curved
ends (serving as pen rack) of the arms A A the mouth of the inkholder, or the mouths
of the inkholders, shall be open and free of access and vice versa, when a penholder
or the like is in position on the ends of the arms A A the mouth of the inkholder or
the mouths. of the inkholders shall be closed.
Second-In connection with inkstands articulated counterbalanced arrangement
of parts substantially as herein described employed for the purpose of ensuring the
automatic opening and closing actions respectively, referred to in the preceding
claim.
