PROVISIONAL SPECIFICATION.
An Improved Adjustable Attachment in connection with
Writing Pens.
We, GEORGE CURTIS of 11 Air Street Regent Street, London, W., Tobacconist,
and AUGUST EMIL ADOLPH BURMISTER, of 6 Chesterfield Street King's Cross,
London, Gentleman do hereby declare the nature of this invention to be as
follows:-
Our object is to provide an adjustable attachment for use with all kinds of
ordinary writing pens, whereby, the same are converted into reservoir or fountain
pens at will.
With this object a tongue of metal, vulcanite, celluloid, or other
suitable material of any size and shape, is formed to fit loosely to either side of the
pen. This tongue is firmly affixed preferably to an india rubber or other flexible
band, but it may also be made in the form of a spring clip in one piece, in lieu of
the flexible band. The tongue is fixed to the pen either by the spring clip, or the
rubber band, and can be removed when required or replaced by a new one.
Dated this 10th day of January 1891.

COMPLETE SPECIFICATION.
An Improved Adjustable Attachment in connection with
Writing Pens.
We, GEORGE CURTIS of 11 Air Street Regent Street London, Tobacconist, and
AUGUST EMIL ADOLPH BURMISTER of 6 Chesterfield Street King's Cross,
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 :-
This invention relates to an improved attachment for ordinary writing pens, the
objects thereof being:
(1) The prevention of blots caused by the too sudden flow of ink from the pen.
(2) To obviate the necessity of frequently dipping the pen into the ink.
For the carrying out of this invention we construct our reservoir attachment as
herein described having reference to the accompanying drawings in which :
Fig. 1. represents a side view.
Fig. 2. a plan view of one side &
Fig. 3. a plan view of the reverse side of the attachment.
Figs. 4 & 5 show two views of a pen with the attachment affixed thereto.
Like letters of reference indicate corresponding parts in all the figures.
Our attachment or reservoir, is formed of a strip or tongue of metal, celluloid,
vulcanite or other suitable material a of the requisite thickness & dimensions, one
end of which is tapered to a point, preferably rather rounded in form, & turned up
or curved slightly as shown at b. The broad end is bent into the form of a flat
hook C, in which a ring of some flexible material, such for instance as india-rubber, d
is inserted after which the hook is pressed together, thereby securing the flexible
ring d firmly in position.
The reservoir attachment may, if desired be fixed to the pen by forming the strip
or tongue with a clip, but for reasons to be hereinafter stated we prefer the flexible
band.
Some of the reservoir pens now in use, are stiffened or hardened by the addition

slipped on any ordinary pen when required, & owing to the flexible nature of the
elastic band, the smooth action or flexibility of the pen, is in no way impaired by
its addition. Although held firmly in position by the rubber or flexible band, the
attachment can be either removed or adjusted at any time. Another advantage
gained by the use of our attachment is, that the rubber ring does not corrode on the
pen as in the case of a metal clip.
The improved reservoir attachment herein described is specially applicable for
the prevention of blots, as although a considerable quantity of ink is retained, after
dipping, in the reservoir formed between the attachment & the pen, as clearly
shown at e. Figs. 4 & 5, yet the too sudden flow of ink is effectually prevented by
the close proximity of the point to the under surface of the pen, which causes the
ink to flow evenly to the point of the pen as required for use.
b
Should the pen require cleaning, the reservoir attachment can be turned back for
that purpose & it will return to its original position by the elasticity of the rubber
band when released, thus saving both time & trouble.
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:
The reservoir attachment for affixing to ordinary writing pens constructed as
herein specified, & attached to the pens by means of a flexible band as substantially
described & set forth in the Specification, & illustrated in the accompanying
drawings.
