PROVISIONAL SPECIFICATION.
A Reservoir Attachment for Writing Pens.
We JOHN CLARK, of Lillian Cottage, Burghill Road, Sydenham, S.E.
Examining Officer, H.M.'s Customs, and MARTHA ABBOTT of 76, Fort Road,
Bermondsey, London, S.E., do hereby declare the nature of this invention to be as
follows:-
Our invention relates to an improved reservoir attachment for writing pens
which can be readily applied by the user to any form of pen for the purpose of
maintaining a more copious supply of ink to the point than the pen would otherwise
contain.
Our improved reservoir attachment consists of a taper strip of india rubber
provided at each end with an eye or loop the loop at the one end being adapted to
be sprung over the shoulder of the pen and the loop at the other end being much
smaller so as to embrace the pen just above the point.
When so applied the body portion of the strip lies partly in and partly encloses
the hollow at the underside of the pen so as to form a sort of capillary chamber in
which a comparatively large quantity of ink will be retained and from which it will
flow to the point of the pen.
The elasticity of the strip retains it in the desired position upon the pen, and is
such as in no way to interfere with the flexibility of the pen nibs in writing.
The device would be made by stamping out from a sheet of rubber, which may
be specially prepared to render it incorrodible by the ink.
Dated this 3rd day of March 1893.

which renders it incorrodible by the ink.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
Our invention is a taper piece of vulcanized rubber with an eye or loop at each
end for attachment to any description of pen or nib thus forming a reservoir for
the ink.
