PROVISIONAL SPECIFICATION.
Improvements in Drawing and like Pins.
1, HENRY MARLES, of 72, Cobden Road, Brighton, in the County of Sussex,
Joiner, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in what are known as drawing pins, and
carpet or drugget pins, the object being to provide a pin which can be easily
inserted, which has a firm hold and which can be easily withdrawn, the head of the
pin being practically flush with the paper or other fabric held by the pin.
In carrying out my invention I make the pin proper with a screw thread or a
portion of a screw thread on that part next the head, and I make the head of my pin
from thin metal stamped or otherwise formed into a curvilinear shape so that when
the pin is placed in its holding position the edge of the head lies close to the paper
or other fabric. To remove the pin it is turned so as to raise the edges from
the paper when the pin can be pulled out in the usual manner. The head of
the pin is perforated or otherwise suitably roughened to provide a hold for
turning the pin down close and for loosening it to allow of removal.

COMPLETE SPECIFICATION.
Improvements in Drawing and like Pins.
I, HENRY MARLES, of 72, Cobden Road, Brighton, in the County of Sussex,
Joiner, 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 improvements in what are known as drawing pins, and
carpet or drugget pins, the object being to provide a pin which can be easily
inserted, which has a firm hold and which can be easily withdrawn, the head of the
pin being practically flush with the paper or other fabric held by the pin.
In carrying out my invention I make the pin proper with a screw-thread or a
portion of a screw-thread on that part next to the head, and I make the head of my pin
from thin metal stamped or otherwise formed into a curvilinear shape so that when
the pin is placed in its holding position the edge of the head lies close to the paper
or other fabric. To remove the pin it is turned so as to raise the edges from
the paper when the pin can be pulled out in the usual manner. The head of
the pin is perforated or otherwise suitably roughened to provide a hold for
turning the pin down close and for loosening it to allow of removal.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which :-
Figures 1, 2 and 3 are an elevation, an underside view and vertical section
respectively of a drawing pin constructed according to my invention; and,
Figures 4 and 5 are sectional views illustrating the construction of a modified
form of pin and the mode of using the same.
Similar reference letters indicate corresponding parts throughout the drawing.
a is the head of my drawing pin, and b, b are the openings formed therein. c is the
pin proper, and d is the screw-thread formed around the same. As represented

page_text: in Figures 1, 2 and 3 this thread has a very sharp pitch and extends only once
around the said pin but it is to be understood that a thread of any other suitable
pitch and length of thread may be employed.
With a pin constructed as described it is obvious that to apply it, it is necessary
to give it a slight rotation in the required direction at the same time that it is
being pressed or driven in so as to afford a firm hold for the thread, the pin
being turned in the reverse direction when being removed, the holes b, b serving
to prevent the finger from slipping on the head instead of turning the pin.
In practice I have found that the same results are obtained by arranging the
pin proper obliquely to the head, as shewn in Figures 4 and 5, the pin being
removed by rotating the same. Figure 4 shews the position of the pin when
in use, and Figure 5 shews the position of the same when turned half a
revolution.
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 :-
The manufacture and use of drawing pins, and carpet or drugget pins, sub-
stantially in the manner hereinbefore described and illustrated in the accompanying
drawing.
