Improvements in Drawing Compasses.
I, ALFRED HAVILAH WOODWARD, of Legge Lane, in the City of Bumingham,
Manufacturer, do hereby declare the nature of this invention to be as follows.-
-
This invention relates to drawing compasses, principally for use in schools
and the like, and has for its object, to provide a simple and efficient means
of securing a pencil or pen or the like to the short leg of the instrument.
The invention consists in the employment of a levering attachment for clos-
ing the grip or pencil holder part, which is fitted to or formed at the end of
the short leg The said gripper or holder consists of an inverted U or staple-
shaped piece of metal, the sides of which are slightly concaved and have either,
plain, seriated or claw-like ends, whilst the upper or return back end 18 cen-
tially pierced to facilitate the introduction of a pencil or pen holder from the
said top end The fixed or standside of the gip is made fast to the short leg
of the compass and two shape or brackets proceed from it and cross the open
sides of the holder and have bearing holes adapted to receive the trunnion ends
o side ears of a fastening level, having a turned-down short end beating
against the fire side of the gripper, the said lever being so arranged that when
closed down, its short end bears against and forces the free leg of the compass
against the inserted pencil, which is thereby firmly held, whilst when the short
end has been turned past the centie, the device is made self-locking and the
gupped pencil cannot be removed until the level 18 again lifted.
By making the sides or legs of the gripper of a cuived or concaved section,
they are slightly flattened when the locking lever is turned down and varying
sized pencils on the like may be gripped, as the said slides yield slightly and
readily lend themselves or conform to the size of the article to be held.
As a modification, the gripping side of the holder may be formed by a separate
cambered or howed or pressure plate, secured to the article to prevent its loss
by headed or turned over ears on its edges working in gaps of the brackets or
straps which carries the fastening lever, whose turned down short end acts upon
the pressure plate and tends to straighten or flatten the same to create the
necessary grip.

page_text: I, ALFRED HAVILAH WOODWARD, of Legge Lane, in the City of Birmingham,
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.-
This invention relates to drawing compasses, principally for use in schools
and the like and has for its object, to provide a simple and efficient means of
securing a pencil or pen or the like to the short leg of the instrument, this
being effected by the employment of a levering attachment for closing the grip
or pencil holder part, which is fitted to or formed at the end of the said short leg.
Figure 1 of the accompanying drawing represents an elevation of a school
compass provided with a lever-closed grip or pencil holding attachment con-
structed in accordance with one form of my invention This view shows the gup
closed upon a pencil, which is thereby igidly secured in its adjusted position
to the short leg of the instrument
Figure 2 18 another elevation of the compass, but showing the gup or holder
opened and the pencil detached therefrom
Figure 3 is an edge view of Figure 1.
Figure 4 represents a vertical section of the grip and a portion of its carrier
leg upon the dotted line a, Figure 3, with the said gup in its closed position,
whilst Figure 5 18 a similar sectional view, but with the gup in its opened
position.

Figure 6 is a view showing the carner leg of the instrument in section upon
the dotted line 2, Figure 5, and the grip or pencil holder in topside plan,
whilst Figure 7 18 another plan of the said holdei, looking from underneath
Figure 8 18 a plan view of the sheet metal blank from which the body part
of my improved grip or holder may be fashioned.
The same letters of reference indicate corresponding parts in the several
figures of the drawings
According to this form of my invention, the pencil holding attachment or
gupper consists of an inverted U or staple-shaped piece of metal forming the
body part a, the sides a¹, a³, of which are slightly concaved and preferably
have serrated or claw like ends a³, whilst the upper or return back end a 19
centrally pierced at b, to facilitate the introduction of a pencil c, or pen holder
into the grip from the said top end The fixed side a¹, of the gap is made fast
to the short leg d, of the compass d, and two straps or brackets « proceed
from it and cross the open sides of the holder and have bearing holes as adapted
to receive the trunnion ends or side ears e¹ of a fastening lever e, having a
turned-down short ende, bearing against the free side a³, of the gripper, the
said lever being so arranged that when closed down, its short end bears against
and forces the free leg of the compass inwards against the inserted pencil, which
is thereby firmly held, whilst when the short end has been turned past the
centre, the device 18 made self-locking and the gupped pencil cannot be re-
moved until the lever is again lifted
By making the sides or legs of the gripper of a curved or concaved section,
they are slightly flattened when the locking lever is turned down and varying
sized pencils or the like may be gripped, as the said sides yield slightly and
readily lend themselves or conform to the size of the articlo to be held
body part a, of the grip is preferably fashioned from the sheet metal blank
represented in plan in Figure 8.
The

page_text: 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
I claim 18
First In compasses, the employment of a jointed levering attachment for
closing the grip or holder part upon the pencil or other article to be held, sub-
stantially as herein described, and also as set forth in the accompanying drawing.
Secondly. In compasses, the employment of a grip or holder consisting of
a U or staple-shaped body part, having an opening or gap at the return end
for the introduction of a pencil or the like, with one side of the same being
free whilst the other side is attached to the short leg of the instrument, in con-
Junction with fixed brackets or ears to which a double-armed lever 18 jointed,
with the short arm being adapted to impinge upon the fiee limb of the grip
and close it onto the article to be held, substantially as herein described, and
also as set forth in the accompanying drawing
