PROVISIONAL SPECIFICATION.
Improvements in Drawing Pins.
I, GEORGE SIMMINS, of Crawley, in the County of Sussex, Estate Agent, do
hereby declare the nature of this invention which has been communicated to mo by
Walter F. Brett, of Greymouth, New Zealand, to be as follows :—
This invention relates to drawing-pins, such as are used by draughtsmen and
others to attach the paper, on which they intend to work, to the drawing board, and
for similar purposes.
Unless ordinary drawing-pins aro pressed home very thoroughly the head of the
pin does not press on the paper, and the paper is held against lateral motion by the
stem of the pin only, and if the paper bo thin, as for instance thin tracing paper, it
often gives way or tears, and thus becomes loose and sometimes escapes altogether
from under the head of the pin, and even the most careful attention to the fixing of
the pins does not always suffice to prevent this.
Now according to this invention the under side of the head of the drawing pin
is cushioned with a disc or washer, or piece, or pieces, of soft or elastic material so
that when the pin is pressed in, the washer presses on the surface of the paper,
thereby in addition to holding it by the stem of the pin, holding it between two
surfaces, that is to say, between the washer on the under side of the head of the
pin, and the drawing board, instead of holding it by the stom of the pin only, thus
my invention enables a draughtsman to fix the paper much moro securely, and with
less liability to damage or mark the surface of the papor, and with less necessity for
care and attention than heretofore.

Improvements in Drawing Pins.
I, GEORGE SIMMINS, of Crawley, in the County of Sussex, Estate Agent, do
hereby declare the nature of this invention and in what manner the game is to be
performed which has been communicated to me by Walter F. Brett of Greymouth,
New Zealand, to be particularly described and ascertained in and by the following
statement:-
This invention relates to drawing-pins such as are used by draughtsmen and
others to attach the paper on which they intend to work to the drawing board, and
for similar purposes.
Unless ordinary drawing-pins are pressed home very thoroughly the head of the
pin doos not press on the paper, and the paper is held against lateral motion by the
stem of the pin only, and if the paper be thin as for instance thin tracing paper it
often gives way or tears, and thus becomes loose and sometimes escapes altogether
from under the head of the pin, 'and even the most careful attention to the fixing
of the pins does not always suffice to provent this.
Now according to this invention the under side of the head of the drawing-pin
is cushioned with a disc or washer, or piece, or pieces, of soft or elastic material
Buch for instance as indiarubber so that when the pin is pressed in, the washer
presses on the surface of the paper, thereby in addition to holding it by the stem
of the pin, holding it between two surfaces, that is to say, between the washer on
the under side of the head of the pin and the drawing board instead of holding it

paper much more securely, and with less liability to damage or mark the surface
of the paper, and with less necessity for care and attention than heretofore.
Figure 1, is an elevation of a drawing-pin made according to my invention;
Fig. 2, is a perspective view of the same;
Fig. 3, is a view of such a pin with the washer removed, and
Fig. 4, is a perspective view of the washer separately.
a is the head of the pin and the stem or point thereof both of which are similar
to those of ordinary drawing pins except that the stem or point is longer; c, is the
washer formed of a soft and yielding friction producing material for which purpose
I have found vulcanized rubber answer better than any other substance as its
nature causes it with very slight pressure to hold the paper very firmly.
The comfort and advantage of using my improved pins is so great that
draughtsmen who have once used them, are not likely to be contented to use the
old ones afterwards.
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. The improvement in drawing pins herein before described and shown in the
drawings.
2. Drawing pins formed with a washer or pad of soft or elastic material on the
under surface of the head substantially in the manner and for the purpose herein-
before described.
