PR VISIONAL
Apparatus for Raising the Frame of Typewriting Duplicators and
Mimiographs and the like.
ARTHUR ODLUM WILKINSON 6 Foster Place Dublin Typist and Scrivener
do hereby declare the nature of this invention to be as follows:-
As in copying letters and other documents by means of typewriting duplicators
mimiographs and various kinds of copying apparatus it is at present necessary to
raise the frame containing the stencil by means of the hand and in order to facilitate
the turning out of a larger number of copies within a shorter time than by raising
the frame by the hand I cause the frame to rise by providing same with a strip of
rubber of sufficient size and shape, one end of which I attach to the frame, and
the other end I attach to a perpendicular rod, or the like which is fastened at the
side of the frame or the top where it is hinged or fastened, said rod having
notches or holes for graduating the spring or length of the rubber so as to raise
said frame to a more or less extent as required. The perpendicular rod or support
is so made & fastened that it can be taken off or made to fold down. Both ends of
the rubber, are provided with means of attaching & detaching.

ARTHUR ODLUM WILKINSON 6 Foster Place Dublin, Typist and Scrivener,
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 has for its object the raising of the frame or lid of the several
kinds of copying apparatus, and in order to facilitate the faster reproduction of
matter and in shorter time than by raising the frame or lid of copying or other
apparatus, by hand or other inconvenient method, I cause same to rise by attaching
a perpendicular rod marked "B" on accompanying drawing, to the back of the
apparatus this perpendicular rod fits or slides into a little socket marked "A
which is screwed or otherwise fastened to the back of apparatus. I then apply a
piece of rubber "C" one end of which is provided with an ordinary hook. I screw
an eye book into the frame or lid, the farthest end from the hinges, and I
then hook on the rubber, the other end of rubber I attach to the said perpendicular
rod by passing it thro' three holes bored in said rod, which gives it a firm grip
and prevents it from slipping, and by this means the rubber can be drawn up or
loosened so as to keep the frame or lid in a higher or lower position as required.

page_text: Thus the frame or lid of any duplicating apparatus or the like with my device
attached will be self-raising when pressed down and let go. It will be seen that
the details & mode of attachment such as the size & shape of rubber and
perpendicular rod and the fastening of same may be altered or varied in a multitude
of ways according to the requirements of any particular apparatus, for instance, the
upright rod "B" may be made to fold down by means of a pivot or otherwise when
not in use, and not to slide into socket "A" as shown.
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 :-
A rubber device acting as a spring or pressure attached to any duplicating
apparatus or the like with the object of making the frame or lid self-raising.
