PROVISIONAL SPECIFICATION.
Improved Penholder.
ALFRED BIRCH Engineer 34 Great Cheetham Street Lower Broughton Man-
chester do hereby declare the nature of this invention to be as follows:-
I place two jaws each with a swelled or wedged shoulder on its back within a
wood or metal tubular case. The aforementioned shoulders I make to project a
little beyond the case. The jaws I make of a curved shape or otherwise as will
best grip a pen-nib, the convex side of one jaw to press against or into the concave
side of the other jaw. I cause them to grip or press together by arranging a metal
spring to pull the jaws towards and the shoulders partially into the tubular case;
and I cause them to open and release the pen by extending the shanks of the jaws
so as to project beyond the opposite end of the tubular case to allow of the jaws
being slid down by the finger so as to bring the thinner part of the wedge-shoulders
in contact with the mouth of the tubular case. I make the jaws to open either by
fixing a pin between the shank of each jaw or by providing sufficient outward spring
in the shanks themselves. Or the inner side of the tubular case itself I make make
to act as one of the jaws and only have a single jaw and shank to slide or move
and the convex side of this jaw will press into the concave inner side of the tubular
case.

COMPLETE SPECIFICATION.
Improved Penholder.
ALFRED BIRCH Engineer 34 Great Cheetham Street Lower Broughton Man-
chester, Lancashire 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 :—
I place two jaws, one or both having a swelled or wedged shoulder on its back,
within a wood or metal tubular case.
The shoulder or shoulders I make to protrude partially outside the case.
The jaws I may make of a curved or other shape as will best grip a pen-nib.
I cause the jaws to grip or press together by arranging a metal or other elastic
spring to pull the jaw or jaws towards, and the shoulder or shoulders partially into
the tubular case, and 1 enable the jaw or jaws to open and release the pen by
extending the shank or shanks of the jaw or jaws-so as to protrude beyond the
contrary end of the tubular case-to permit of the jaw or jaws being pressed and
slid down by the finger which will cause the thinner portion of the wedge-shoulder
or shoulders to come in contact with the mouth of the tubular case.
I make the jaw or jaws to open by fixing a pin between the jaw-shanks, or by
providing sufficient outward spring in the shank or shanks themselves.
Or the inner side of the case itself I may make to act as one of the jaws, against
which the moving or sliding jaw will press and grip the pen.
In the drawing A is the tubular case; B and C the jaws; e the finger push to
which the jaw shanks are attached; D is the spring drawing up the shanks and
thereby causing the jaws B and C to grip together, which action grips the pen, g is
a washer against which the spring rests and F illustrates one of the methods of
securing the jaw-shanks to the finger push.

page_text: 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 :-
One or two jaws, protruding from within a tubular case, wedge-shaped in such a
manner that in being pulled in towards the mouth of the case by a spring or springs,
the wedged form of jaw or jaws will cause said jaw or jaws to approach one another
or approach the inner side of tubular case.
Dated this Twenty-eighth day of December 1892.
