Complete Specification Left, 7th July, 1900-Accepted, 11th Aug., 1900
An Improved Military Sketching Board.
I, SYDNEY SOLOMON LAWRENCE, trading as Lawrence & Mayo, of 67 and 69,
Chancery Lane, in the County of London, Optician, do hereby declare the nature
of this invention to be as follows:-
The invention has for its object an improved military sketching board whereby
the use of rubber bands is dispensed with and the difficulties involved in their
use, namely their loss, deterioration and misplacement, are obviated.
For this purpose I employ a band or strip of leather or other suitable material
(not rubber) and at one end I attach a flat coiled spring, which latter is provided
with means to attach it to the sketching board; the other end of the leather
or other strip or band is also fastened to the sketching board. Preferably I
attach a short piece of leather or other suitable material to the flat coiled spring,
and I form grooves or depressions in the sketching board frame to receive the
spring band flush with the surface thereof.

An Improved Military Sketching Board.
I, SYDNEY SOLOMON LAWRENCE, trading as Lawrence & Mayo, of 67 and 69,
Chancery Lane, in the County of London, Optician, do hereby declare the nature
of this invention and in what manner the same is to be performed to he
particularly described and ascertained in and by the following statement:
The invention has for its object an improved military sketching board whereby
the use of rubber bands is dispensed with and the difficulties involved in their
use, namely their loss, deterioration and misplacement, are obviated.
I will describe my invention by the aid of the accompanying drawing in
which, Fig. 1 is a front view, Fig. 2 a back view and Fig. 3 a longitudinal
section on the line 1-1 of Fig. 1 of a military sketching board provided with
my improvements. a is the body of the sketching board, b, c, the top and
bottom bars or clamps, da compass, e, e the paper rollers, f, f the springs
for holding the rollers e, e in position and permitting their ready removal,
g, g clips for holding a pencil. The bottom bar or clamp ċ has a scale on the
front and back edges thereof.
The parts above referred to are of the character usually found in a military
sketching board.
According to inv invention I dispense with the rubber bands usually emnloved

page_text: and I use in lieu thereof a band or strip h of leather or other suitable material
(not rubber) having a flat coiled spring at one end thereof, which spring is
provided with means to attach it to the sketching board; preferably I attach
a short piece 2 of leather or other suitable material (not rubber) to the flat
coiled spring h¹ and I form grooves or depressions b, c respectively in the
top and bottom bars or clamps b, c, to receive the ends h2, h3 of the spring
band h, h¹ flush with the surface of the board to which said ends h², hare
secured by screws or by other suitable means. i is a ruler which is kept in
position by the spring bands and j is a leather strap to secure the sketching
board to the arm as is well understood.
It will be evident that the construction of the spring bands may be modified
without departing from the peculiar character of my invention.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
1. A military sketching board having fixed thereto spring bands constructed
substantially as herein set forth in lieu of the loose india rubber bands ordinarily
employed.
2. In a military sketching board the substitution for the loose india rubber
bands ordinarily employed of spring bands fixed to such sketching board, such
spring bands being formed of leather or other suitable material otlier than
rubber and having a flat coiled spring attached to one end thereof substantially
as herein set forth.
