An Improved Reservoir Attachment for Pens.
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 to be as follows:-
This invention relates to reservoir attachments for pens of the kind which are
fitted on the upper or convex side of the nib or writing part of the pen by means
of an end part made in the form of a split cylinder, or segment of a cylinder,
or by means of spring or other clips. Devices of this character have hitherto
been made of a stiff and inelastic material so that pens fitted therewith, and
especially quill pens, are stiff and hard to write with and after a little use the
material becomes deformed or bent and the device is then quite useless for its
purpose.
The object of this invention is to so construct pen reservoir attachments of the
class hereinbefore described as to obviate the disadvantages indicated, and to
produce a reservoir attachment which allows the flexibility required, especially in
quill pens, and which can be fitted to steel pens or nibs of different sizes and of
various shapes.
According to this invention I connect the attachment end part of the device to
the spoon shaped reservoir thereof by means of a thin strip of springy metal. Or,
instead of, or in addition to, the spring connection between the attachment end and
reservoir, I split the nib end of the spoon shaped reservoir longitudinally along
the centre for a convenient distance down from the extreme nib end towards the
attachment end.

An Improved Reservoir Attachment for Pens.
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 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 upper or convex side of the nib or writing part of the pen by
means of an end part made in the form of a split cylinder, or segment of a
cylinder or by means of spring or other clips. Devices of this character have
hitherto been made of a stiff and inelastic material so that pens fitted therewith,

and especially quill pens, are stiff and hard to write with and after a little use the
material becomes deformed or bent and the device is then quite useless for its
purpose.
The object of this invention is to so construct pen reservoir attachments of the
class hereinbefore described as to obviate the disadvantages indicated, and to
produce a reservoir attachment which allows the flexibility required, especially in
quill pens, and which can be fitted to steel or other pens or nibs of different sizes
and of various shapes.
According to this invention I connect the attachment end part of the device to
the spoon or scoop shaped reservoir thereof by means of a thin strip of springy
metal. If found desirable the nib end of the spoon or scoop shaped reservoir may
be split longitudinally or transversely.
In the accompanying drawings I have shown how my invention may be carried
into practice and have shown various modifications and the method of adaptation
to various kinds of pens and penholders. The same letters of reference where
they occur, are used to denote the same or corresponding parts in all the figures.
Fige. 1 and 2 are respectively longitudinal elevation and section of part of an
ordinary quill pen with my reservoir attachment fitted thereon. A is the rear or
attachment end which in this case is made in the form of a split cylinder, B is
the spoon or scoop-shaped reservoir which is shaped so as to conform to the shape
of the nib or writing end of the quill pen, and 66 are ridges, or projections of any
suitable kind formed on or secured to the inner side of the reservoir B to keep the
latter at the proper capillary distance from the writing end of the pen when fitted
thereto. C is a thin and preferably narrow strip of springy metal connecting the
two parts A and B or the whole device may be made in one piece from a metal
which is sufficiently resilient to allow of the requisite flexibility. The device is
fitted to the pen by passing the split cylinder end A thereover until the reservoir B
lies in proper position over the writing end of the quill pen, where it is maintained
at its proper capillary distance by the spring part C and the ridges or projections b
on its under side.
Figs. 3 and 4 are similar views of a magnum-bonum or barrel pen with a slightly
modified reservoir attachment. In these figures the reservoir B is shown somewhat
in the shape of a scoop or shovel with a forward prolongation or tongue 61 which
is turned slightly upwards as shown in the drawings. This modified form is
applicable to quill pens, and both this form and that illustrated in Figs. 1 and 2
can be fitted to ordinary holders taking steel or other nibs.
Figs. 5, 6 and 7 show modifications of the device illustrated in Figs. 3 and 4.
Fig. 5 is a plan showing the device with a central longitudinal split 62, which
however may be located to one side if so desired instead of centrally as shown, and
more than one such split 62 may be used if preferred. The device shown in Fig. 5
is furthermore provided with two or more ridges or projections 6 which are formed
by stamping two strips or tongues in its body and turning these under in the
manner shown by Fig. 7, which is a cross-section through the line E F of Fig. 6.
Fig. 6 is a view similar to Fig. 5 and differs only in having a transverse split 63 in
addition to the longitudinal split 62, and in having the ridges b formed by turning
under strips stamped or cut in its outer edges instead of in its body as in Fig. 5.
Figs. 8 and 9 are, respectively longitudinal elevation and section of a steel or
other nib or slip pen with my reservoir attachment fitted thereto and which is
secured by slipping it together with the slip end of the nib, into the shank D in
the ordinary way.
In this case the rear or attachment end A of the device is
made so as to conform to the shape of and lie upon the slip end E of the nib as
shown in Fig. 10, which is a cross-section taken on the line G H of Fig..9.
Fig. 11 is a view similar to Fig. 9, but in this case the device is secured to the
slip end E of the nib by means of clips or turned under ends a as shown in Fig. 12,
which is a cross-section taken on the line J K of Fig. 11.
The longitudinal and transverse splits described with reference to Figs. 5 to 7
can be applied in the same manner to any of the other forms of my invention.

page_text: In all the forms of my invention it is essential that the reservoir B should be
connected to the attachment end A by a springy metal connection C so that when
in use the nib end of the device will partake of all the movements of the nib or
writing end of the pen, and the requisite flexibility thus secured.
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 comprising an attachment end and a reservoir
chamber connected by a springy metal connection and adapted to be fitted on the
upper or convex side of the pen and constructed substantially in the manner
respectively described with reference to Figs. 1 and 2, 3 and 4, 5 to 7, 8 to 10, or
11 and 12 of the accompanying drawings.
Dated this 8th day of March 1897.
