1, MALCOLM ARBUTHNOT ALVES, of 43 Cromwell Houses, Queen's Gate, in
the County of Middlesex, Lieutenant Colonel Royal (late Bengal) Engineers,.
retired, do hereby declare the nature of this invention to be as follows:-
This invention relates to reservoir attachments for pens of the kind which are
fitted on the under or concave side of the nib or writing part of the pen. Devices
of this character as heretofore made have been found unsatisfactory in use either.
on account of the loose and uncertain manner in which they fit into the nib or writing
part of the pen, or by reason of not drawing up the ink properly.
The object of this invention is to produce pen reservoir attachments of the class:
hereinbefore referred to in which the above mentioned disadvantages are obviated.
The device which forms the subject of this invention is at one end made in the
shape of a tongue or scoop, open at the sides, flat or Hattish in cross section and.
straight or curved longitudinally; and at the other end is a longitudinal prolongation
having a curved cross section. The tongue or scoop aforementioned serves as the
reservoir, and the curved prolongation conforms to the shape of and fits under the
concave extension of the nib or writing part of the pen, and with it, is passed into,.
and secured in position by, the side clips on the shank or body part of the.
pen-holder. In this way the device is securely held in place with the tongue or
scoop lying immediately under and against the under side of the split end of
the nib.

I, MALCOLM ARBUTHNOT ALVES, of 43 Cromwell Houses, Queen's Gate, in
the County of Middlesex, Lieutenant Colonel Royal (late Bengal) Engineers
retired, 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 reservoir attachments for pens of the kind which are
fitted on the under or concave side of the nib or writing part of the pen. Devices
of this character as heretofore made and used have been found unsatisfactory
in use either on account of the loose and uncertain manner in which they fit
into the nib or writing part of the pen, or by reason of not drawing up or holding
the ink properly.
The object of this invention is to produce pen reservoir attachments of the
class herein before referred to in which the above mentioned disadvantages are
ohriated

page_text: The device which forms the subject of this invention is at one end made in the
shape of a tongue or scoop, open at the sides, flat or flattish in cross-section and
straight or curved longitudinally; and at the other end is a longitudinal pro-
longation having a curved cross-section. The tongue or scoop aforementioned
serves as the reservoir holding the ink by capillary attraction and the curved
prolongation conforms to the shape of and fits under the concave extension of the
nib or writing part of the pen, and with it, is passed into, and secured in position
by, the side clips or other holding arrangement on the shank or body part of
the pen-holder. In this way the device is securely held in place with the tongue or
scoop lying immediately under and nearly touching the under side of the split end
of the nib.
In the accompanying drawings, which are furnished in illustration of my
invention,
Figs. 1 and 2 are respectively longitudinal elevation and section of a nib or slip
pen A with my reservoir attachment B fitted thereto and slipped into a shank C of
ordinary construction;
Figs. 3 and 4 are cross-sections respectively taken on the lines
Fig. 2;
and yy of
Figs. 5 and 6 are respectively elevation and plau of the reservoir attachments
shown in Figs. 1 and 2; and
Figs. 7 to 9 show longitudinal sections of slightly modified forms of my reservoir
attachment.
The same letters of reference where they occur are used to denote the same parts
in the various figures.
My reservoir attachment consists of a plate of any suitable material B which is
open at the sides and flat or flattish in cross-section as shown in Fig. 4, and may
be made either as a straight scoop or tongue connected by a shoulder to the
rear end b as shown in Fig. 5, or it may be curved longitudinally as shown in
Figs. 7, 8 and 9. This plate B is inclined or curved towards the point of the nib
in such a manner as to give the capillarity required to form the reservoir chamber
and its rear end b is downwardly curved in cross-section as shown in Fig. 3, to
correspond with the curvature of the rear end of the nib or slip pen A. Both the
nib and the rear end 6 of the reservoir device can be slipped together into the
shauk C of the penholder, and the device is securely held by the spring or other
side clips or holding arrangement which serve to hold the nib or slip pen A in
the shank C.
.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is ;-
A reservoir attachment for pens consisting of a plate open at the sides, flat or
flattish in cross-section and straight or curved longitudinally and made in the form
of a scoop or tongue inclined or curved towards the nib point so as to form a
capillary reservoir chamber, and a downwardly curved rear prolongation to said
reservoir attachment to fit under the concave rear extension of an ordinary nib or
slip pen and adapted to be slipped with it into the shank of the penholder
substantially as described and illustrated and for the purpose stated.
