Improvements in and Additions to a Combined Pencil, Pen-holder,
and Drawing Compass.
1, GEORGE HENRY TWIGG of the firm of Robinson, Son and Twigg of Legge Lane.
Birmingham in the County of Warwick, Manufacturer, 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 said instrument consists essentially of a hollow stem, herein-after called the
leg stem, fitted at one end with a reversible pencil, and eraser tip carrier, and at the
other end with a reversible pen carrier, which is so arranged, that when the pen is
sheathed, or passed into the interior of the leg stem, the other end of the said
carrier, constitutes the terminal to the compass, and by which means, the compass is
rotated.
Surrounding the leg stem, is an open-jointed and adjustable slide, to which the short
leg of the compass is jointedly connected, and which said short leg has impressed
upon its outer side, longitudinally disposed scales, viz.: inches and millimetres.
When the instrument is not in use, the pencil and pen are respectively turned
inwards, within the leg stem, while the lower end of the leg stem, and the short leg,
are covered by a protector or shield, which has impressed upon it, postal scales of
charges.
Figure 1 of the accompanying drawings, represents my new or improved combined
instrument folded up, and protected by a shield or sheath. Figure 2 represents the
same in use, as a lead compass. Figure 3 represents the instrument as a pen compass,
and figure 4 shows the said instrument divested of its short leg, and used as an
ordinary penholder or pencil. Figure 5 is a side elevation of the short leg separately,
and figure 6 is a front elevation, exhibiting the scale markings upon its outer side.
Figure 7 represents the opened out sheath, or the sheath blank, which exhibits the
postal markings.
The same letters of reference indicate corresponding parts in the several figures.
a is a leg stem, (see figure 3) having an axial hole up its middle, thus forming an
open-ended tube, in one end of which, the tubular carrier 6 is fitted, having an eraser

page_text: tip c, and pencil d, fitted in its respective ends; and which said carrier is provided
with a shoulder stop 62, for limiting its inward movement. The other end is provided
with a pen carrier e, in one end of which is placed a pen f, whilst the other end g is
left plain, and constitutes a terminal to the compass leg stem, when the lead is used.
The carrier has a limiting stop e², like that of the other part before described.
Clipping the leg stem a, is an open-jointed and adjustable slide h, which carries a
short compass leg i, preferably trough form in cross section, and with its inner end ³,
which is made fork like, jointedly connected to the said slide, by bulging outwardly
the metal thereof, into eyelets 23, which are passed through holes made in the inner
ends, and there riveted or closed over, thus forming the joint, which can be readily
stiffened on wear,
by a slight impact imparted to it, by a hammer.
The outer or convex side of the leg, is longitudinally impressed with inch and
millimetre scale, so that the leg as well as forming a part of the compass, constitutes a
double scale measuring rule.
The end of the compass and leg stem, are protected by a sheathj, having impressed
upon it, inland postage, and parcel post tariffs.
When the combined instrument is required to be used, as a compass, remove the
sheath, and open out the short leg, and with the pen or pencil carrier, fitted within
the lower end of the leg stem, as shown at figures 2 and 3, with the leg carrying
slide adjusted to the desired length.
To use the instrument as a pen and pencil holder, remove the slide and leg, and
place a pen or pencil carrier in position, as may be desired, or as represented in
figure 4.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is :
First: A combined instrument, consisting of pen, pencil and compass, as described
and set forth in figures 1, 2 and 3.
Secondly: A combined instrument, consisting of hollow leg stem a, pencil
carrier b, 6², carrying either a pencil or an eraser at one end, or at both ends; a pen
carrier or holder e, e², g², at the other end, and an adjustment slide, with compass
leg h, i, 2; and which said parts, are constructed, arranged and used, substantially
as, and for the purpose, as described and set forth.
:-
Thirdly Connecting the leg of a compass i, to its carrying slide, by a forked inner
end or ears, secured by an eyelet bulging of the slide part, as set forth.
Fourthly The combination with a pen, pencil and compass, as constructed, of a
sheath j, as set forth in figure 1.
Fifthly Combining with a sheath j, of a scale of inland postage and parcel post
tariffs, as set forth in figures 1 and 7.
Lastly-Arranging upon the leg of a compass, inch and millimetre scale, as set
forth in figure 6.
