Improvements in Pens
I, OLOF WINKLER, Clerk, of Norra Tiadgardsgatan, 17, Helsingborg, Sweden,
do hereby declare that the nature of this invention, and in what manner the same
18 to be performed, to be particularly described and ascertained in and by the
following statement:-
This invention relates to improvements in pens, and has more particular relation
to reservoir pens.
The invention consists of a reservoir pen, comprising a hollow body portion, a
flexible cap or bulb upon one end of said body portion, and an adjustable air inlet
valve projecting through an opening in said cap and provided with an inclined
recess
The invention also consists of certain other novel constructions, combinations
and arrangements of parts, all of which will be hereinafter more particularly set
forth and claimed.
In the accompanying drawings, forming part of this specification,
Figure 1 represents a perspective view of the pen embodying my invention
Figure 2 represents a central vertical longitudinal section through the same
Figure represents an enlarged detail perspective view of the plug or valve
1 in the drawings represents the body portion, 2 the pen clamp, 3 the bulb cap
and 4 the regulating plug or valve
Said body portion 1 is preferably constructed of glass and is cylindrical in form
as shown in the drawings The lower end of said body portion is reduced and
curved as illustrated, so as to bring its discharge end in alignment with the
exterior of said cylindrical portion The clamp 2 18 preferably constructed of
metal and 18 adapted to be adjustably secured to the cylindrical portion 1 by spring
clamping arms 5 which closely hug said cylindrical portion The downwardly
extending portion of said clamp is formed with inwardly turned flanges
between which the pen 8 is slipped It will be observed from the foregoing
description that the lower curved end of the body portion will discharge laterally
against the interior of the pen 8 The cap 3 for closing the upper end of the
cylindrical body portion is preferably constructed of rubber and comprises an
attaching sleeve 9 and a rubber filling bulb 10, the latter being provided in its
upper portion with a plug aperture 11 adapted to receive the regulating plug 4.
This latter comprises an eye 12 and a shank 13, the latter formed with an inclined
recess 14
It will be observed from the foregoing description that when the shank portion
18 partly withdrawn from the bulb 10 the supply of air to the interior of the body 1
will be cut off When it is desired to cause the ink to flow from the lower end
of the body portion on to the pen, the plug 4 is accordingly pushed forward so as
to cause the recess 14 to come into alignment with the opening 11 which will
admit air to the bulb 10 By the peculiar inclined formation of said recess 14, the
air inlet port may be increased or decreased in size by simply pulling
the plug 4 out or pushing the same in When it 18 desired to
fill the body portion I with ink, the bulb 10 is first compressed with

page_text: the fingers, the lower end of the body portion being inserted into an ink bottle
01 other receptacle Upon releasing said bulb 10 the same will expand, the valve
being closed, and the ink will be drawn up into the body portion.
It will be observed from the foregoing description that the clamp 2 may be
readily slipped along upon the body portion 1 so as not to discharge the ink upon
the upper portion of the pen 8 The flow from the lower discharge end of said
body portion may also be regulated at will
Thus pen 18 very simple and cheap in construction, and at the same time secured
the best possible results as the flow of ink 18 entely under control at all times or
may be shut off altogether by forcing the shank portion of the plug within the
bulb.
By the pecular construction of the body portion, the ink does not contact with
any portion of the metal holder 2, and the latter is therefore prevented from
becoming corroded or discolored
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. In a reservou pen, the combination with a hollow body portion, of a flexible
cap or bulb upon one end of said body portion, and an adjustable air inlet
valve projecting through an opening in said cap, the said valve provided with an
inclined recess, substantially as and for the purpose set forth
2. In a reservoir pen, the combination with a hollow body portion, of a flexible
closing cap upon the upper end of said body portion provided with an opening,
and a plug valve adapted to fit within said opening provided with an inclined
recess in one of its sides, whereby by a change of position of said plug valve in said
cap said opening may be completely closed or the size thereof regulated, as and for
the purpose set forth
