page_text: GEORGE HERBERT LOCK, 44, Wright Street, Hull, Minister of Religion, and
Writer, do hereby declare the nature of this invention to be as follows:-
It consists of the shape and inter-relation of pieces B and C, as described below.
Piece A is a tube of glass or vulcanite or other suitable material, closed at one
end and open at the other. This is the reservoir.
Piece B is a tube of vulcanite or other material, about one inch in length and
half an inch in external diameter, or any other suitable size. About half of its
length is made to be screwed or cemented into the open end of piece A. It is
open at one end; and at the other end it is partially closed by a disc pierced at
the edges with holes graduated in size. The entire internal wall of this tube is
lined a thin coating of india-rubber.
Piece C is a tube of vulcanite about one and a half inches long, or other suitable
size. About two thirds of its entire length must be of such diameter as to fit into
the india-rubber-lined channel of piece B tightly enough to prevent a flow of ink
between the two pieces, but not so tightly as to prevent piece C, when lubricated,
from sliding in and out of piece B when a reasonable degree of force is applied
with the fingers. The remaining one third of the length must be of larger dia-
meter. In the wall at the end of this thicker portion, and horizontal with its
length, a semi-circular aperture or hole must be sunk of sufficient size and depth
to hold the shank of an ordinary nib. This thicker end of the tube C is open;
the smaller end is partially closed by a disc in the edge of which is pierced a hole.
The external side of this disk is coated with a thin layer of india-rubber except
where the hole is pierced. The length of the smaller two thirds of piece C
must be such that, when pushed as far as it can go into piece B, the external sur-
face of its disc shall press against the internal surface of the disc in piece B, in
order that, when piece C is twisted or turned round in that position, the hole in
its disc may co-incide with one of the graduated holes in the disc of piece B.
Piece D is a tongue of vulcanite about two thirds of an inch long and about one
eighth of an inch broad, or other suitable size. On one side it must have a flat
surface on the other side it must be bulbous towards one end, while at the other
end it is tapered down to a thin square edge. At the bulbous and it must have a
suitable projection by which it can be cemented into the open end of piece C. The
flat face must be placed towards the aperture in piece C (into which the nib is
inserted). The projection must be so shaped on that side, that a minute hole is
left through which ink may flow from piece C in between piece D and the nib. A
very small channel must be made diagonally through the bulbous portion, one
end of which must open in the middle of the flat face of piece D, and the other end
into the channel of piece C.

GEORGE HERBERT LOCK, 44, Wright Street, Hull, Minister of Religion, and
Writer. I 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:-
The invention consists of an arrangement by which the flow of ink from the
reservoir A to the nib, may be regulated, which is secured by the form of, and
inter-relation between, pieces B and C as hereinafter described.
Piece A is a tube of vulcanite or any other suitable material, closed at one end,
and open at the other end. This piece is the reservoir.
Piece B is a tube of vulcanite or any other suitable material, about one inch in
length and half an inch in external diameter, or any other suitable size, and with
a wall of about one sixteenth of an inch thick. About three eighths of an inch of
the length of B must be made to be screwed, or otherwise suitably fastened, into
th open end of A, in such a manner that no ink can escape between pieces A
and B, and so that A and B may be readily separated.
B must be closed by a disc at the end made to be inserted into A. This disc
must be perforated with holes e, f, g, h, which must exactly coincide in size and
position with the holes contained in the disc in C as hereinafter described. One
hole in the disc of B must coincide with the air-passage in C so that thereby
air may be admitted into A, while ink escapes through e f g.
The internal wall of B and of its disc must be evenly lined with a thin level
coating of cork or other suitable material K, which must be cemented to the wall.
The holes e f g h must be carried through the lining of the disc.
Piece C is a cylinder of vulcanite or other suitable material. A sufficient por-
tion of its length must be of such diameter as to fit into the open end of B tightly
enough to prevent ink from escaping between the external wall of C and the lining
in B, but not too tightly for C to be turned or twisted round in B by reasonable
pressure of the fingers. The length of this portion of C must be the same as the
length from the lining of the disc in B to the open end of B.
:
C must be pierced through its entire length by two canals, one of which must
pass through the centre of C for the passage of ink the other canal i must lie
between the central canal and the external wall of C, and is for the passage of air.
At the end which is to be inserted into B, the central canal must be so enlarged
that it may receive ink through several holes e, f, g, in the disc in B. This same
end of C must be closed with a disc which shall have holes pierced through it to
exactly coincide with the holes in the disc in B. One hole h in the disc of C must
be a continuation of the air passage i, so as to allow the passage of air through
the corresponding hole in the disc in B and thus into the reservoir.
C is to be pushed into B so that the external side of its disc shall lie or press
close against the lining on the disc in B.
The remaining length of C must be of larger diameter, and may be of any con-
venient shape on the outside. Its external end must be adapted to hold a nib,
and also a tongue ]) by means of which air may be admitted to the air passage i,
and ink he carried from the central canal in C to the nib. The relative position of
the holes in the two discs must be indicated by suitable marks on the outside of B
and C.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:
That the novelty of my invention consists in the from

so that the two discs are in contact and the holes coincide, the flow of ink is
unimpeded; and when B is turned in C, the holes cease to coincide and the flow of
ink is diminished or stopped.
