PROVISIONAL SPECIFICATION.
Improvements in and relating to Pocket Drawing Compasses.
We, JOHN HEWITT, of 58 Graham Street, in the City of Birmingham,
Manufacturer, and FRANCIS ROBERT BAKER, of Harborne, in the County of
Stafford, Engineer, do hereby declare the nature of this invention to be as
follows:-
Our invention relates to improvements connected with pocket compasses, the
object being to produce a simple and efficient means of adjusting the pencil
or pen carried therein, and also to provide combination articles upon the
compasses.
In carrying our invention into effect we make our compasses from metal, one
leg or limb being formed suitable for carrying a pencil or a pen, and having a
frame or sliding bar which travels up and down upon the leg which is formed to
carry the pencil or pen holder so that by the movement of the sliding bar in au
inclined or tapering direction the pencil or the pen holder is tightened and its
position adjusted to suit the point of the other leg.
We form the frame or the holder of the pen or pencil with a channel like opening
running down the centre having the end enlarged to form a bed for the pencil or
the pen holder, while the opposite end we shape and bend so as to enclose or
embrace the leg or limb of the other part of the compasses, and through the two we
place a rivet upon which each portion may turn.
We make the other member or limb of the compasses sometimes in the
form of a knife blade, one end being made as a point upon which the compasses
may swing, the other being attached to the end of the pencil holder by means of
the rivet.
Instead of employing a knife in combination with the point of one limb, we may
make it as an ordinary pointed bar for the instrument to turn upon, and we make
the bar or the blade of the knife to pass between the open rib formed upon the
opposite member which carries a pencil, so that the blade or bar is enclosed or
protected when not in use.
For convenience of manipulation we sometimes place a handle over the end of
the rivet head making the handle with a bridge piece to pass over the outer sides
of the engaging ends and thus to cover the joint before the rivet is passed
through.
We modify the shape of the holder to suit the pencil or pen which is to be
carried, and we make one part from steel and the other from any other suitable
metal when so desired, varying the shape and arrangement of the sliding tightening
piece to suit the form of the pencil or holder which is to be carried.

Improvements in and relating to Pocket Drawing Compasses.
We, JOHN HEWITT, of 58 Graham Street, in the City of Birmingham,
Manufacturer, and FRANCIS ROBERT BAKER, of Harborne, in the County of
Stafford, Engineer, 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 :-
Our invention relates to improvements connected with pocket compasses, the
object being to produce a simple and efficient means of adjusting the pencil
or pen carried therein, and also to provide one article in combination upon the
compasses.
In the accompanying sheet of explanatory drawings
Figure 1 is a side elevation showing our combination compasses fitted with a
pencil and knife blade.
Figure 2 is a plan of the same.
.
Figures 3 and 4 are elevations of our compasses made without the blade point or
blade limb.
Figure 3 is an end view of the pencil holder.
In carrying our invention into effect we make our compasses from metal, one leg
or limb A being formed suitable for carrying a pencil or a pen, and having a
frame or sliding bar or clip B which travels up and down upon the leg which is
formed to carry the pencil or pen holder so that by the movement of the sliding
bar or clip over an inclined or tapering portion of the leg A the pencil or
the pen holder is tightened and its position adjusted to suit the point of the
other leg c.
We form the frame or the holder a, of the pen or pencil with a channel like
opening a running down the centre having the end enlarged to form a bed for the
pencil or the pen holder, while the opposite end u³ we shape and bend so as
to enclose or embrace the leg or limb c of the other part of the compasses,
and through the two we place a pin, screw or rivet D upon which each portion
may turn.
We make the other member or limb of the compasses sometimes in the form
of a knife blade c', one end being made as a point c upon which the compasses
may swing, the other being attached to the end of the pencil holder by means of
the rivet D.
Instead of employing a knife in combination with the point of one limb, we may
make it as an ordinary pointed bar for the instrument to turn upon, as in Figure 3
and Figure 4, and we make the bar or the blade of the knife to pass between
the open rib shown in end elevation in Figure 34 formed upon the opposite member
which carries a pencil, so that the blade or bar is enclosed or protected when not
in use.
For convenience of manipulation we sometimes place a handle E over the end
of the rivet head making the handle with a bridge piece e, to pass over the
outer sides of the engaging ends and thus to cover the joint before the rivet
is passed through. We sometimes use washers F under the rivet heads or
we employ one washer as a nut into which the end of the rivet may be screwed.
We modify the shape of the holder to suit the pencil or pen which is to
be carried, and we make one part from steel and the other from any other
suitable metal when so desired, varying the shape and arrangement of the
sliding tightening piece to suit the form of the pencil or holder which is to be
carried.

page_text: We make our handle E from solid bar or from strip or sheet metal bent to the
desired shape.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is;-
(1.) The combination compasses and blade or knife formed as one instrument
or one article substantially as herein before described and as illustrated in the
accompanying drawings.
(2.) The improvements in pocket compasses substantially as hereinbefore
described and as set forth in the accompanying drawings.
(3.) In compasses the tightening or clipping bed for holding the pencil or
the like, in which a bar slide or clip moves along an inclined part of the
limb and compresses the end of the holder or bed substantially as and for the
purposes hereinbefore described and as illustrated in the accompanying drawings.
