PROVISIONAL SPECIFICATION.
Improvements in Blackboards.
I EDWARD WILLIAM TAYLOR of 74 Chancery Lane in the County of
Middlesex Shorthand Writer, do hereby declare the nature of this invention to be
as follows:-
A contrivance more especially adapted for use as a blackboard for educational
purposes; the essential feature being that instead of written or drawn letters,
figures, signs, marks, diagrams, drawings, and the like, movable characters of any
description such as alphabetical letters, numerical figures, shorthand signs, music
notes, and the like, are caused to adhere to the blackboard when the latter is in a
vertical or any other position.
The means by which the movable characters are made to adhere to the blackboard
are either
--
(a) By projections such as pegs, pins, screws, hooks, rings, and the like, from the
movable characters, which projections can be fitted into holes, grooves, slots,
cavities, or attachments in or upon the blackboard.
(b) By projections such as pegs, pins, screws, hooks, rings, and the like, from the
blackboard, which projections can be fitted into holes, grooves, slots, cavities, or
attachments in or upon the movable characters.
(e) By appliances such as pegs, pins, screws, hooks, rings, attachments, and the
like, which although not permanently fixed to either the movable characters or
the blackboard may be temporarily used for connecting the movable characters with
the blackboard.
(d) By suspension from any part of the blackboard.
(e) By beds sunk or cut in the blackboard into which the movable characters
may be fitted.
(1) By projections from the blackboard upon which the movable characters may
be supported.
(g) By nagnetic attraction.
(h) By adhesive matter.
The blackboard may be constructed of wood, slate, metal, composition, or any
suitable material.
The colour of the surface of the board although preferably black is not necessarily
of the latter description.
The sunk beds referred to serve also as guides wherein to trace with chalk or
otherwise diagrams or marks corresponding with such beds.
The invention may partly be described as a blackboard on which movable
characters are caused to adhere and on which board diagrams or marks may be
accurately shewn by tracing their forms with chalk or otherwise in corresponding
beds sunk in the board..
Dated this 16th day of September 1893.

page_text: I EDWARD WIlliam Taylor of 74 Chancery Lane London, Shorthand
Writer and Teacher 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 :-
•
A contrivance more especially adapted for use as a blackboard for educational
purposes the essential feature being that instead of written or drawn letters, figures,
signs, marks, diagrams, drawings, and the like, movable characters of any description
such as alphabetical letters, numerical figures, shorthand signs music notes,
illustrations of the principles of Euclid, and the like are caused to adhere to the
blackboard when the latter is in a vertical or any other position.
The means by which the movable characters are made to adhere to the blackboard
are either
(a) By projections such as pegs, pins, screws, hooks rings, and the like, from the
movable characters which projections can be fitted into holes, grooves, slots,
cavities, or attachments, in or upon the blackboard.
(b) By projections such as pegs, pins, screws, hooks, rings, and the like, from the
blackboard, which projections can be fitted into holes, grooves, slots, cavities, or
attachments, in or upon the movable characters.
(e) By appliances such as pegs, pins, screws, hooks, rings attachments, and the
like, which although not permanently fixed to either the movable characters or
the blackboard, may be temporarily used for connecting the movable characters
with the blackboard.
(d) By suspension from any part of the blackboard.
(e) By beds cut or sunk in the blackboard, into which the movable characters
may be fitted.
By projections from the blackboard upon which the movable characters may be
supported.
((✓) By magnetic attraction; magnets being fixed to the back of the board,
which magnets must be of sufficient power to attract through the blackboard and
cause to adhere to the latter any thin iron or steel characters or characters having
in their construction any material liable to be attracted by a magnet; or the black-
board itself may consist of or contain a sheet of iron or steel, or any material liable to
be attracted by a magnet, and be connected with an electro magnet for the purpose
of causing the characters to adhere to the blackboard.
(h) By any adhesive matter such as wax and the like.
The blackboard may be constructed of wood, slate, metal composition or any
suitable material and may be of any dimensions.
The colour of the surface of the board although preferably black, is not
necessarily of the latter description.
The sunk beds referred to serve also as guides wherein to trace with chalk or
otherwise diagrams or marks corresponding with such beds.
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
A blackboard upon which movable characters of any description, such as
representations of alphabetical letters, numerical figures, shorthand signs music notes,

page_text: illustrations of the principles of Euclid, and the like, are caused to adhere to the
blackboard when required, instead of such characters being drawn or written upon
the blackboard.
Dated this 16th day of September 1894.
