COMPLETE SPECIFICATION.
Improved Inkpot for School Desks.
I, LUDWIG BOHM, of Prenzlauer Allee No. 26, Berlin Germany, Secretary, do
hereby declare the nature of my invention and in what manner the same is
performed to be particularly described and ascertained in and by the following
statement:-
The present invention consists of an inkpot for school desks specially designed
with a view to preventing the ink from becoming thick through long standing.
This object is attained by arranging the inkpot moveably, so that on opening or
closing the same it will be necessary to move the pot from a vertical to a horizontal
position or vice versa.
And in order to render the present specification more easily intelligible reference
is had to the accompanying drawings in which similar letters of reference denote
similar parts throughout the several views :-
Fig. 1 is a vertical longitudinal section through the inkpot and that portion of
the desk in which it is arranged, the inkpot being closed,
Fig. 3 is a similar section showing the position of the pot when in use or open,
Fig. 2 is an end elevation of the pot,
Fig. 4 a plan view of the same.
Fig. 5 is a section on line x-y of Figure 6 showing a modified form of pot,
Fig. 6 is a vertical section through the inkpot and adjoining parts of the desk
with the pot closed,
Fig. 7 is a section along the line a y¹ of Figure 8,
Fig. 8 is a similar section to that of Figure 6 showing the pot in the position
occupied when in use,
Fig. 9 is a plan of this form of pot.
Fig. 10 shows a further modification of the inkpot in vertical longitudinal
section, the pot being closed,
Fig. 11 is a similar section with the pot open and
Fig. 12 is a plan of Figure 10.
Referring to Figures 1 to 4 :-These figures represent the simplest form of the
invention. The same consists of an inkpot having a body and a throat g,
partially separated from the body by an indentation in the glass. The desk is
provided with a cavity a having a downwardly extending projection c and a cover d
with hinge e as shown at Figures 3 and 4.
When the inkpot is in use it is placed in the cavity a of the desk b in a hori-
zontal position as shown at Figure 3 and when not in use it is turned on end and
put into the downwardly extending portion of the said cavity a in the manner
shown at Figure 1. The proportions of the pot are such that the ink cannot flow
out even when the pot is quite full, when the same is turned down horizontally,
the indentation between the body f and the neck g being of such a depth as to
prevent the air from passing in at y and then to the body f, so that when the
pot
is suddenly turned from the position shown at Figure 1 to that of Figure 3 a
partial vacuum will be formed above the ink in the body which prevents the
same from overflowing at g when the pot is inadvertently filled too much.
In the modification shown at Figures 5 to 9 the lower extension c of the cavity
is hinged to the upper part a of the same and is connected by a rod to the cover d
by means of eyes at k and i. Thus when the cover d is turned back the part c of
the casing or cavity will be swung on its hinges at h and swing the ink pot into the

page_text: horizontal position. The length of the rod is such as to allow the pot to just
occupy the horizontal position when the cover d is thrown back. To facilitate
opening the cover the desk is provided with a cavity at the rear of the hinge and
the cover is provided with a rearwardly extending part m at the opposite side of
the hinge o. In order to open the cover it is only necessary to press on the rear
extension m and swing the cover round on its hinge. In closing the pot it will
only be necessary to press on the part m which as shown at Figure 7 will lie at the
opposite side of the hinge v.
According to the arrangement shown in Figures 10 to 12 the casing c and the
cover d are made in one piece and hinged at h to the desk, said casing being
adapted to turn on its hinge in the cavity a of the desk. When the ink pot is not
in use it stands on end as shown at Figure 10 the part d of the casing covering the
cavity of the desk, and when the pot is in use it is turned round into a horizontal
position the part d being thus turned down at right angles to the upper surface of
the desk. The part d is advantageously provided with a ledge d which rests on
the desk when the pot is closed or out of use and prevents the device from swinging
too far round on its pivot.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is performed I declare that what I
claim is :-
1. An inkpot for use in connection with school desks 'said inkpot being adapted
to lie horizontally in a cavity a of the desk when in use and to be placed vertically
in a downward extension of said cavity when closed substantially as described.
2. A modification of the device covered by Claim 1 according to which the
lower extension of the cavity of the desk is hinged to the upper part a of the cavity
and connected to the cover of the said desk cavity by a rod as specified so that
on opening the cover the inkpot will be turned automatically into the position
required for use and on closing the cover into the position of rest substantially as
described.
3. A modification of the device covered by Claim 1 according to which the
casing e containing the inkpot is provided with a plate d and hinged to the desk
ath said parts being arranged in such manner that on turning the inkpot into
the position required for use the cover d will be moved downwardly whilst on
turning the pot into the vertical position i.e. the position it occupies when closed
the plate d will cover the opening of the desk substantially as described.
