PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at
the Office of the Commissioners of Patents on the 6th July 1880.

The Invention consists in supporting the liquid receptacle by a ring frame
pivoted by horizontal pivots to a second ring which pivots on a horizontal axis
perpendicular to the pivots of the first or inner, ring so as to obtain a sort of
binnacle attachment. Also in making the cover of the receptacle in two halves
hinged to the periphery of the orifice of the receptacle, and opening outwardly
from the centre thereof in order to maintain the equilibrium of the open-receptacle,
each of the said halves being provided with a projection, which, when the receptacle
is open, rests on a band placed around the orifice. Also in providing the circum-
ference of the receptacle with lugs which can be passed down through openings or
recesses of the inner ring and by a turn secure the receptacle in place, the holding
ring being furnished with stops adjoining the recesses by which the correct position
for removing the receptacle can be easily obtained.

securing and holding it in position.

Figure 2 is a side view partly in section of a self levelling ink well for car or
marine purposes.
Figure 3 is a perspective view of a stationary inkwell provided with a pen
rack.
Figure 4 is a plan view of the self levelling inkstand frame and pivoted rings
in which it is hung, said frame being provided with perforations to receive screws
by which it may be secured in position.
Figure 5 is a vertical section through Figure 4.
Figure 6 is a bottom or inverted plan view of Figures four and five.
Figure 7 is a plan view of a stationary inkstand provided with a horizontal arm
for. securing it in position.
Figure 8 is a side view of a stationary inkstand provided with a bracket for
securing it wherever desired.
Figure 9 is a detailed view showing the method of securing the inkwell to the
ring.
Figure 10 is an inverted plan view of Figure 9, showing the stops which
regulate the position of the inkwell when it can be withdrawn or when it is locked
in position.
The object of the Invention is to suspend an inkwell to a frame or bracket, so
that said inkwell shall be kept in constant position, or cork side up, by force of
gravity, as, for instance, in the raising of a desklid' to which the inkstand may be
rigidly attached, so that the inkwell maintains a perpendicular position independent
of the motion of the object to which the inkstand is attached.
Also in the rolling of a ship or swaying of a carriage or car when in motion,
the constant level position of the inkstand is maintained without lateral oscillatory
or swinging motion.
The device it is believed will be especially useful for marine purposes, railway
postal cars, &c., and generally in the construction of desks and secretaries.
In the Drawings, A represents the ink well suspended on pivots B, B, in a
metallic ring C, which operates within another ring E to which the said ring C is
pivoted at B, B.
The ring E is supported in the frame D by the pivots c, c. The pivots are at
right angles and equidistant, thereby causing the axes of their revolution to be
perpendicular to each other. In the stationary inkstand, as shown in Figure 3,
the flange H rests upon the frame D.
In Figure 5 the seal F, F, of the inkwell opens from the centre on hinges, and
its sections are arrested when poised in proper position by the projections G, G,
resting on the band I.
The flange H of the self-levelling inkwells rests upon the ring C, and the lugs
K, K, are made to slide through the recesses L, L, as shown in Figures 6 and 10,
when a partial revolution of the inkstand is made to the left so as to cause the
lugs K, K, to strike against the stops x, x, which are placed on the under side of

page_text: ring C, thereby locking it to the said ring, from which it cannot be released until
the said lugs K, K; strike against the stops y, y, on ring C, when the inkwell is in
position to be readily withdrawn, as the lugs K, K, will then register with the
recesses L, L.
Z, Z, are ears on frame D, and X, X, are the feet upon which the frame rests,
as shown in Figure 4. These feet are provided with countersunk perforations for
receiving the screws in securing them to a desk or other article.
Arms N, as shown in Figures 2 and 7; and bracket O, as shown in Figure 1,
may be attached to ring D, and serve as a means for securing the inkwell to the
sides or wall of a railroad car or to the sides of a vessel.
Having fully described the Invention, what I claim and desire to secure by
Letters Patent is as follows:-
1st. The combination of the hinged seals F, F, provided with projections G, G,
with the band I, substantially as and for the purpose set forth.
2nd. The combination of a binnacle balanced fluid receptacle, and of twin
seals or covers pivoted at the periphery of the orifice of the receptacle and
opening outwardly from the centre thereof, whereby when the seals are open the
equilibrium of the receptacle is maintained.
3rd. The inkwell provided with lugs K, K, which pass through openings or
recesses in the holding ring C or frame D, and by a turn secure the well in place,
substantially as set forth.
4th. The holding ring C or frame D provided with stops y, y, adjoining the
recesses L, L, by which the inkwell is guided so that it may be readily removed
from the ring, as set forth.
5th. As an improvement in inkstands or wells, the combinations of the part A
having lug K with the holding ring C provided with recesses and stops, arranged
as described, and a suitable bracket or stand constructed and applied, substantially
as specified.
6th. As a new article of manufacture, an inkstand consisting of the following
elements, to wit:-The raised annular ring frame D provided with perforated
feet X and ears Z, the gimbal mechanism, and the receptacle A with twin seals or
covers F, F, substantially as described.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Fifth day of January 1881.
