PROVISIONAL SPECIFICATION.
Improvements in Drawing Instruments.
I, GEORGE WRIGHT, of 2 Long Lane, Aldersgate Street, in the City of
London, Stationers' Sundriesman, do hereby declare the nature of this invention to
be as follows:-
This invention for improvements in drawing instruments relates to drawing
compasses and has for its object to provide a compass pencil point or holder of
simple construction which shall be easily and readily adjusted so as to firmly secure
pencils and drawing pens of various sizes.
In one arrangement constructed according to this invention the movable leg of a
pair of compasses comprises two strips bent and crossed over each other and
connected by pins or other pivotting device, the two outer and parallel ends of one
strip being pivoted to the leg while the similar outer ends of the other strip are
pivoted to a block mounted on a screw working in suitable bearings in the said leg
and having a milled head secured thereto for its manipulation. The device thus
constructed forms a kind of lazy tongs which may be opened or closed by the action
of the operating screw so as to clip a pencil or pen, the leg having formed on it
a V shaped groove or channel in the direction of its length and in which the pencil
or pen lies when in position.

COMPLETE SPECIFICATION.
Improvements in Drawing Instruments.
I GEORGE WRIGHT of 2 Long Lane, Aldersgate Street, in the City of
London, Stationers' Sundriesman 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 for improvements in drawing instruments relates to drawing
compasses and has for its object to provide a compass pencil leg or holder of simple
construction which shall be easily and readily adjusted so as to firmly secure pencils
and drawing pens of various sizes.
Referring to the accompanying sheet of illustrative drawings:-
Fig. 1 represents a perspective elevation of a pair of pencil compasses constructed
according to this invention.
The pencil leg a comprises two strips b, c bent as shown and crossed over each
other and connected by pivots d, the two outer and parallel ends of one strip b
being pivoted to the leg a while the similar outer ends of the other strip c are
pivotted to a screwed nut or block e mounted on a screw f working in bearings
at g and h, and having a milled head i secured thereto for its manipulation.
The device thus constructed forms a kind of lazy tongs which may be opened or
closed by the action of the operating screw f so as to receive and clip a pencil or
pen, the part of the leg having formed on its face a hollow or V shaped groove
or channel in the direction of its length and in which the pencil or pen lies when in
position.

page_text: Fig. 2 represents an elevation in perspective of a modification of the pencil leg
end shown in Fig. 1, the pivots d connecting the bent strips bc being dispensed
with.
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:-
1. In drawing compasses: a pencil leg comprising two strips bent and crossed
over each other and having their ends pivotted to the leg and to a sliding nut
mounted on an adjusting screw respectively, the whole substantially as described
and for the purpose set forth.
2. The arrangement and construction of drawing instruments substantially as
described with reference to the drawings.
Dated this 2nd day of November 1894.
