IMPROVEMENTS IN WRITING INSTRUMENTS
Year: 1885

page_text: I WILLIAM FREDERICK BARTON MASSEY-MAINWARING of 30 Grosvenor Place
in the County of Middlesex, Gentleman do hereby declare the nature of the
said invention for IMPROVEMENTS IN WRITING INSTRUMENTS to be as follows:-
The invention relates to improvements in that class of writing instruments in
which the holder forms a reservoir for the ink or writing fluid and consists of a
novel construction of parts whereby freedom of action is obtained and a constant
flow of ink is secured, so long as the writing instrument is in' use and until the
reservoir is exhausted.
For this purpose I employ a hollow holder the lower end of which I contract and
provide with a spring needle or wire to loosely fit the same and to project slightly
therefrom in a similar manner to that adopted in what is known as the "stylo-
graphic pen."
According to my invention however instead of writing with the contracted end
of the instrument and with the spring, needle or wire in contact with the paper or
other surface to be written from, I'mount on a suitable axis at the' writing end of
the holder a small wheel formed on its periphery with shallow transverse undulations
and with one or more circumferential grooves.
f
The spring needle or wire bears against the periphery of the wheel and as the
said wheel is caused to revolve when the writing instrument is in use the said
needle or wire will be caused constantly to move to and fro thereby ensuring a
constant flow of ink to the wheel which latter in revolving over the paper .or
other writing surface conveys the ink to said surface, the ink being conducted
thereto by flowing round the circumferential groove or grooves in the wheel.
If desired the spring needle or wire in the holder and the transverse undulations
around the periphery of the wheel may be dispensed. with, in which case the wheel
would be caused to close the aperture in the holder when not in use, and as before
described, to convey the ink from the said aperture to the paper when in use.
The wheel in both cases when revolved clears the aperture of any corroded or
coagulated ink which may have accumulated thereon.
The wheel bas its periphery of a convex form and the holder has its end made
of a corresponding concave form in order that the two may fit together."
The support for the wheel is adjustable on the holder.

page_text: I WILLIAM FREDERICK BARTON MASSEY-MAINWARING of 30 Grosvenor Place
in the County of Middlesex, Gentleman, 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 relates to improvements in that class of writing instruments in
which the holder forms a reservoir for the ink or writing fluid and consists of a
novel construction of parts whereby freedom of action is obtained and a constant
flow of ink is secured so long as the writing instrument is in use, and until the
reservoir is exhausted.
For this purpose I employ a hollow holder the lower end of which I contract and
provide with a spring needle or wire to loosely fit the same in a similar manner to
that adopted in what is known as the "stylographic pen."
According to my invention however instead of writing with the contracted end
of the instrument, and with the spring needle or wire in contact with the paper or
other surface to be written upon, I mount on a suitable axis at the writing end
of the holder a small wheel formed on its periphery with shallow transverse
undulations, and with one or more circumferential grooves.
The spring needle or wire bears against the periphery of the wheel, and as the
said wheel is caused to revolve when the writing instrument is in use, the said
needle or wire will be caused constantly to move to and fro, thereby ensuring a
constant flow of ink to the wheel which latter in revolving over the paper or other
writing surface conveys the ink to said surface, the ink being conducted thereto
by flowing round the circumferential groove or grooves in the wheel.
If desired the spring needle or wire in the holder and the transverse undulations
around the periphery of the wheel may be dispensed with, in which case the wheel
would be caused to close the aperture in the holder when not in use, and as before
described, to convey the ink from the said aperture to the paper when in use.
The wheel in both cases when revolved clears the aperture of any corroded or
coagulated ink which may have accumulated thereon.
The wheel has its periphery of a convex form and the holder has its end made
of a corresponding concave form, in order that the two may fit together. The
support for the wheel is adjustable on the holder.
And in order that my said invention may be more clearly understood and readily
carried into effect, I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a longitudinal section and Figure 2 is an outside view of a writing
instrument showing one method in which I carry my invention into effect.
Figure 3 is a longitudinal section showing a slight modification.
Figures 4 and 5 are two outside views showing a further modification, and
Figures 6 and 7 are respectively a side view, and an edge view of the marking
wheel. Figures 1 to 5 are drawn to a scale of three times the actual size of the
marking instrument. Figures 6 and 7 are drawn to a scale of twelve times the
actual size and Figure 8 represents the marking wheel drawn to its actual size.
In the arrangement shown at Figures 1 and 2 a represents a hollow holder the
lower end of which is contracted and provided with a spring needle or wire 6 to

page_text: loosely fit the aperture in the lower end of the same in a similar manner to that
adopted in what is known as the "stylographic pen." According to my invention
however instead of writing with the contracted end of the instrument and with the
spring needle or wire in contact with the paper, or other surface to be written
upon, I mount on an axis c at the writing end of the holder a small wheel & formed
on its periphery with shallow transverse undulations d¹ and with one or more
circumferential grooves d².
The axis c of the wheel d is carried by a cap a¹ which fits closely the end of the
contracted part of the holder a and is adjustably held in position thereon by the
internally screw threaded ring a' which screws onto a screw thread formed on
the holder as shown or the wheel d may be adjustably held in position on the
holder a in any other convenient manner.
The spring needle or wire b bears against the grooved periphery of the wheel d
and as the said wheel is caused to revolve when the writing instrument is in use
the said needle or wire b will be caused constantly to move to and fro thereby
ensuring a constant flow of ink to the wheel d which latter in revolving in contact
with the paper or other writing surface conveys the ink to said surface, the ink
being conducted thereto by flowing round the circumferential groove or grooves d³
in the wheel d.
If desired the spring needle or wire 6 in the holder and the transverse
undulations d around the periphery of the wheel d may be dispensed with, as
shown at Figure 3 in which case the wheel d would be caused to close the aperture
in the holder when not in use, and as before described, to convey the ink from the
said aperture to the paper when in use.
The wheel d in both cases when revolved clears the aperture of any corroded
or coagulated ink which may have accumulated thereon.
The wheel d has its periphery of a convex form and the holder has its end made
of a corresponding concave form in order that the two may fit together.
In the modification shown at Figures 4 and 5 instead of fitting the wheel d to
a tubular reservoir holder as above described, the reservoir for the ink is formed
of a number of plates or leaves a³ of metal or other material between which the
ink is held and which supply the ink to the wheel d by means of the longer of
such plates a³ which at its lower end is in contact with the wheel d and is so
shaped as to fit closely against same.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what
I claim is:-
1. A writing instrument in which ink is supplied from a reservoir holder to a
revolving wheel which supplies said ink to the paper or other writing surface,
substantially as herein shown and described.
2. A writing instrument consisting of a reservoir holder a with or without a
spring needle or wire b and a revolving wheel d adjustably fixed to the contracted
end of the reservoir holder a and fitting within a recess formed in such end
substantially as herein shown and described and for the purpose stated.
3. The wheel d formed with circumferential groove or grooves d2 and with or
without transverse grooves or undulations d' substantially as herein shown and
described and for the purpose stated.
