Complete Specification Left, 1st Jan., 1900-Accepted, 3rd Feb., 1900
An Improved Teaching Appliance for Containing and Displaying
Maps, Diagrams, Black Surface Sheets and the like.
We, COLIN SIMS, of 44, Bond Street, Leigh, in the County of Lancaster,
Publisher, and WRIGHT SCHOFIELD, of Brockholes, near Huddersfield, in the
County of York, Publisher, do hereby declare the nature of this invention
to be as follows:-
It is an improved arrangement for preserving a number of maps, charts,
pictures, diagrams, drawing copies, reading sheets, or black-surface sheets for
chalk or crayon illustrations, and holding them in such a manner that each
sheet can be readily displayed to a class.
The customary arrangement is to fasten a number of sheets to a lath, roller,
or metal strip, or between two laths or strips of metal, whereas we employ two
sheets of cardboard, or other similar material. which may be hinged like the
covers of a book, or which may be separate. At the corners of these backs, eyelet
holes are made, through which rings are put, and which rings are constructed
so as to readily open and close for the purpose of adding, or taking off sheets.
Holes are likewise perforated in the corners of the sheets, through which the
rings are put, and the complete arrangement resembles a book the leaves and
backs of which, instead of being stitched, turn on the aforesaid rings.
The portfolio can be readily opened to any page, and hung up in the usual
manner, or put on an easel, for the purpose of the class lesson.
When not in use the stiff backs are closed, and serve to protect the sheets
from dust and injury. They also form a firm surface and support for the
sheets whilst the teacher is writing or drawing on them.

We, COLIN SIMS, of 44, Bond Street, Leigh, in the County of Lancaster,
Publisher, and WRIGHT SCHOFIELD, of Brockholes, near Huddersfield, in the
County of York, Publisher, 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:-
It is an improved arrangement for preserving a number of maps, charts,

page_text: pictures, diagrams, drawing copies, reading sheets, or black-surface sheets for
chalk or crayon illustrations, and holding them in such a manner that cach
sheet can be readily displayed to a class.
The customary arrangement is to fasten a number of sheets to a rod, roller,
or metal strip, or between two rods or strips of metal, whereas we employ two
sheets of cardboard or other suitable material, which may be hinged like the
covers of a book, or which may be separate.
The sheets and covers are perforated and held together by rings. The com-
plete arrangement resembles a book, the leaves and backs of which instead of
being stitched, turn on the aforesaid rings.
These rings may be constructed so as to readily open and close for the purpose
of adding or taking off sheets when necessary.
The portfolio can be readily opened to any page or hung up in the usual
manner, or put on an easel, for the purposes of the lesson.
When not in use the stiff backs are closed and serve to protect the sheets
from dust and injury. They also form a firm surface and support for the
sheets, whilst the teacher is writing or drawing on them.
Figure A represents the portfolio open, on an easel.
Figure B represents it hung up with one of the covers and some of the leaves
turned behind.
Figure C represents the portfolio closed.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
A portfolio for teaching purposes, the backs and sheets of which are held
together by, and turn on rings; the latter may be ordinary closed rings, or such
as will readily open and close for adding or taking off sheets.
