Improvements in and relating to Reservoir Attachments to Pens.
I GEORGE HENRY HOLLAND CLEMENT of 102 Queens Road, Norwich,
Surveyor of Taxes 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 object of my invention is to provide a new or improved device to serve as a
reservoir, which, when attached to any pen or nib having a central slot of the
usual oblong or oval shape will allow of the said pen or nib receiving and holding
an increased supply of ink and thereby ensuring the economisation of time, and the
promotion of speed in writing; which advantages will be readily recognized as
being of the greatest importance.
The device according to my present invention is affixed to the pen by inserting
its two central and narrow ends into the central slot above referred to, thus
resulting in a formation resembling that of a half-hoop on the upper or convex side
of the pen between which and the surface of the pen, the ink is retained by capillary
attraction.
In the accompanying sheet of drawings illustrative of my invention, which are
all on an enlarged scale,
Figs. 1, 2 and 3 are plan views of three different forms of the blank from which
my improved device is made.
Figs. 1, 2, and 3ª are corresponding side views illustrating the adaptation of
the finished device according to my invention to a writing pen or nib.
Fig. 4 is a plan of a writing pen or nib provided with the device according to
my invention, in its finished form made from a blank of the shape shewn in Fig. 1.
Fig. 5 illustrates the shape of blank which I employ to make that modification
of device in accordance with my invention when same is affixed to the concave
instead of to the convex side of a pen or nib; and,
Fig. 5 is a side view of said modification shewing its adaptation to a pen or nib.
Like letters of reference are employed to denote corresponding parts throughout
the drawings.
According to my said invention I form by means of a punch, stamp, die or other
known or suitable mechanical methods a blank B of the shapes shown in Figs. 1,
2, 3 and 5 out of a sheet of thin steel or other suitable material of a springy elastic
or resilient nature. These blanks B are subsequently punched stamped pressed or
otherwise caused to assume the forms of which side views are shown in Figs. 1ª,
24, 34 and 54. In the case of blanks shown in Figs. 2 and 3, said formation is
effected by forcing the larger ends c in an upward and the smaller ends 6 in a
downward direction.
The ends a and 6 of the devices shown in Figs. 1, 2 and 5 can now be readily
bent between the forefinger and thumb, so as to enable them to be inserted into
the slot of the pen or nib p in which position as soon as the pressure of the
fingers is removed, they are securely held by the natural resilience or elasticity
of the metal or other substance, of which the devices in accordance with my
invention are made. The device shewn in Fig. 3 is affixed to the pen p in the
same manner as last above described except that the end b must first be turned
sideways to enable it to enter the slot.
In the spaces formed between the ends c and the upper or convex surface of the
pens shown in Figs. 2 and 3^, ink may be retained by capillarity and the storing
capacity of the pens will by means of my invention be thereby materially
increased.

page_text: The notches & are intended to facilitate the flow of ink from the reservoir to the
point of the pen.
By forming in pens of suitable size and shape a second slot or hole at the rear of
the ordinary slot, I may fix thereto devices of greater length than the devices B
and thus increase the storing capacity of the pens having my invention adapted
thereto.
I
form a
As a modification of the herein before described arrangements may
device the shape of the blank of which is shewn in Fig. 5 and a side view
illustrating its adaptation to a pen or nib in Fig. 5-which may be attached to
the concave instead of to the convex side of a pen or nib.
The device in accordance with my invention possesses amongst other advantages
the one of allowing of its being detached from the pen and sold separately for use
either with an ordinary pen or with the special pen patented by me No. 10977
dated 31st July 1888-and now known and sold as the "Centric" pen.
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 1
claim is :
(1.) A new or improved device serving as a reservoir applicable to pens or nibs
for the purpose of enabling them to store a large quantity of ink at each dip
substantially as described in the Specification and illustrated in Figs. 1, 1ª, 2, 2ª,
3, 3 and 4.
(2.) The modification herein described in which the device serving as a reservoir
is adapted to the concave side of the pen and as illustrated in Figs. 5 and 5* sub-
stantially as herein set forth.
(3.) The contrivance for increasing the storage capacity of the devices in
accordance with my invention that is to say by making a second slot or hole at the
rear of the ordinary slot as herein set forth.
