Improvements in Copying Apparatus.
I, JUAN PABLO JULIA, of 49 Hudson Street, New York, County and State of
New York, United States of America, Merchant, 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 a copying book provided with a tube or roller that may
be attached to or detached from the back of the book and around which the book
may be rolled by hand to effect the copying.
The 'invention consists in the various features of improvement more fully pointed
out in the claim.
In the accompanying drawing:
Fig. 1 is a longitudinal section through the book with the tube attached.
Fig. 2 a perspective view of the book showing it wound upon the tube.
Fig. 3 is a perspective view of the inkstand or cap for closing the end of the
tube.
Fig. 4 a perspective view of the end of the tube.
Fig. 5 a similar view with the book inserted &
Fig. 6 a horizontal section through Fig. 1, on an enlarged scale.
The letters a, a, represent the two flexible covers of a copying book into which
the leaves a', are stitched. The covers a, project rearwardly beyond the leaves as
at a, to form a contracted neck. This neck terminates at its rear end in a
pocket a³, in which there is contained a rod b.
In front of such pocket, a strip c, of rubber or other elastic material is slipped
into the neck, between the covers.
This strip is of triangular shape in cross section and causes the covers a, to
approach each other at the proper inclination from the leaves backward toward
the rod.
d, is a tube of metal, wood, paste-board or other stiff material and provided
with a slit or groove d¹. One or both ends of this tube may be closed by the
cap or inkstand d³, adapted to engage bayonet slots by which they are held in
place.
Within the tube d, there may be contained pencils and other writing utensils,
such as a pen holder, pens, rubber, pen-knife, etc.
In use the tube is connected to the book by removing one of the caps d³, and
slipping the neck a', into the groove d'. This will cause the pocket a³, and rod b,
to be received within the tube and a firm attachment between tube and book will
now be effected, because the rod is of greater diameter than the width of the slit.
To copy a letter, the leaves a, are moistened as usual, the letter is put in place
and the book is wound upon the tube (Fig. 2) when the hand pressure will quickly
effect the copying operation.
During the winding up operation, the triangular strip c, will cause the leaves to
be wound upon the tube without leaving any hollow spaces, which would, of course,
impair the exercise of a uniform hand pressure.
After the letter has been copied, the book is unwound from the tube and the
letter is removed. Of course, copying books of this kind can be made of but a
limited thickness and after one book is filled, it is slipped off the tube and the
latter attached to a new book. In this way, the books can be properly filed away
and the tube can be used upon an unlimited number of books.

invention, and in what manner the same is to be performed, I declare that what
I claim is :
1. The combination of a copying book with a tube adapted to be attached to
and removed from the back of the book, substantially as specified.
2. The combination of a copying book having a rearward projection, with a
slitted tube adapted to receive such projection, substantially as specified.
3. The combination of a copying book, having rearwardly projecting covers,
with a rod b, secured thereto and with a slitted tube adapted to receive such rod,
substantially as specified.
4. The combination of a copying book having rearwardly projecting covers,
with strip c, and rod b, secured thereto, and with a slitted hollow tube adapted to
receive the rod, substantially as specified.
