A New or Improved Educational Apparatus.
I, HORATIO SHEAF, of the National Schools, High Street, Wanstead, Essex,
Schoolmaster, do hereby declare the nature of this invention to be as follows;-
My invention relates to a new or improved educational apparatus for use in
schools and is designed to dispense with the present use of a black board in many
cases and to provide a ready means of giving examples in the various subjects
under consideration and to facilitate subsequent reference thereto when require
either for the purpose of again renewing a particular lesson or course of lessons
or for other reference. In carrying my invention into practice I provide a board
capable of being stood or hung in any desired position. To the top and bottom
of this board are attached suitably formed brackets one on either side for carrying
the ends of the rollers made to revolve therein.
These rollers carry a sheet of linen, paper, or other suitable material capable of
being rolled and wound upon the said rollers between which it stretches and upon
which is written, printed, or otherwise delineated the examples in reading, writ-
ing, drawing, arithmetic or other desired subjects.
A suitable length of material is thus utilised giving several daily lessons or
examples so that each subject when disposed of is wound upon the roller, and
another is then exposed, and so on from day to day.
Suitable handles may be placed upon the ends of the said rollers to facilitate
the turning of the same and the winding of the material in either direction, and
the brackets are so formed that the rollers may be easily taken out and a fresh
set with different subjects or examples substituted at will.
It is evident that this invention may be put to various uses such as means to
illustrate lectures and the like.

I. HORATIO SHEAF, of the National Schools, High Street, Wanstead, Essex,
Schoolmaster, 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:-

page_text: schools, lecture rooms, and other places, and is designed as a substitute for the
black-board commonly in use and also as a ready means for illustrating or giving
examples of the various subjects under consideration, and to facilitate subsequent
reference thereto when required, either for the purpose of again renewing a
particular lesson, or course of lessons, or for other reference.
In carrying my invention into practise I provide a board of any suitable size
and capable of being stood or hung in any desired position. To the top and
bottom of this board and on each side thereof are attached suitable brackets or
plates for supporting the ends of two axles each carrying a roller. To these
rollers are connected the opposite ends of a sheet of linen, paper, or other suit-
able material capable of being rolled and wound upon the said rollers between
which it is stretched and extends along the front face of the board, and upon
which sheet may be written, printed or otherwise delineated the examples in read-
ing, writing, drawing, arithmetic, or other desired subjects.
A suitable length of material is thus utilised giving room for several daily
lessons or examples so that each subject when finished with may be wound upon
one or other of the rollers at the top or bottom of the board, thus bringing
another blank space into view for the use of the operator. A handle is placed
upon a square end of either of the roller axles to facilitate the turning of the
same and the winding of the material in either direction, and the supporting
brackets or plates are formed with curved slots for receiving the ends of axles so
that the rollers may be easily removed and a fresh set with different subjects or
examples, substituted at will.
It is evident that this invention may be put to various uses, such as means
to illustrate lectures and the like.
And in order to clearly understand my invention reference is had to the accom-
panying sheet of drawings in which Fig. 1 is a front elevation and Fig. 2 a
vertical cross section of the apparatus. Fig. 3 is a horizontal section through one
of the rollers, and Fig. 4 is a side elevation of the lower bearing or support.
a is the board, & the top roller and c the bottom one. d is the axle of the top
roller and e the axle of the bottom roller. Upon each of these axles is mounted
a cylinder or cone f, shown in section Fig. 3, which is formed of thick paper,
cardboard, or other similar material and to one of which is glued or otherwise
secured one end of the piece or sheet of paper or other material y to enable it
to be wound thereon.
The other end of the sheet is attached to the cylinder on the axle of the other
roller c, the sheet g being wound upon each cylinder to form two rolls between
which the said sheet is stretched so as to lie flat against the front face of the
board a.
The colour of the sheet may be white, or of different coloured tints, or
black, and upon its front surface are marked the writing, figures, or other subjects,
such as maps, to be illustrated.
The supports for the axles are provided by the metal strips or plates h which
in the example shown extend along each side of the board to the edges of which
they are fixed, and are connected at their top ends by the cross-piece i, provided
with a hole for hanging the board to a wall, and leaving a space k for receiv
ing the upper roller.
The lower ends of the strips or plates are also connected by the cross-piece
leaving the space m for the lower roller. The cylinders or cores f are fixed to
the axles by means of the milled edged discs or nuts n, which engage with screw-
threads on the axles and are screwed tightly against the ends of the said cylinders.
The bearing plates f are formed with the curved open slots fl which serve as
bearings for the ends of the axles and by means of which the rollers may be
removed and others replaced in position as desired. o, o are plates or stops
pivoted at o, and formed with projections of which bear upon the axles to keep
them from shifting, the said stops being turned aside when removing the rollers.
Upon the front of the sheet can be written or otherwise marked the subjects or
lessons to be taught, the drawing showing a portion of a plant for teaching botany,

page_text: and it is evident that by winding up one or other of the rollers and by means
of the handle 2, which may be shifted from one axle to the other, the sheet is
shifted and a blank space provided for the next subject as desired.
Instead of using the slots f and the stop plates o to form the bearings, the
axles d and o may be supported at one end in a hole in one of the plates h, the
other end of the axles being held up by thumbscrews passing through nuts or
bosses on the opposite side plate h. In some cases I may also dispense with the
cores or cylinders f, a wooden or similar kind of axle q being alone used, as
shown in Fig. 5, to which the paper or other material is easily attached, the
thumbscrew, passing through the nut or boss s, supporting one end of the axle
as above described.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
(1) An improved educational apparatus comprising a board fitted at the top and
bottom with rollers upon which is wound a sheet of paper, linen, or other material
having an exposed surface upon which representations of the subjects or lessons
to be taught can be delineated by the teacher or operator upon the portion of the
sheet stretched upon the face of the board between the said rollers substantially
as described.
(2) In an improved educational apparatus the combination of a board a fitted
with rollers and c mounted on axles d and c provided with cylinders or cores f,
a paper or other sheet g, rolled upon the said cores f, plates or supports h for the
axles, cross-pieces and 7, nuts n pivoted stops o, and handle 2 arranged and
operating substantially as described and for the purposes specified.
(3) The modified arrangement of apparatus as shown in and described with
reference to Fig. 5 of the drawings.
