Year: 1885

page_text: I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Proprietor of the Patent
Industrial and Financial Agency 30 Finsbury Pavement London E.C. do hereby
declare the nature of said invention for "A NEW OR IMPROVED APPARATUS FOR
FACILITATING THE STUDY AND TEACHING OF LETTERS, FIGURES SIGNS, MUSICAL
CHARACTERS AND THE LIKE" a communication to me from abroad by Clement
Desire Henri Thureau, Gentleman of N° 11 Rue Berthollet, Paris in the Republic
of France to be as follows:-
The object of this invention is to facilitate the study and teaching of letters,
figures, signs, notes of music, as well as the composition of words (in various types)
and musical passages, and which can be used by the blind.
It consists of
1st A board of suitable size and material for placing the types &c upon.
2nd Moveable types capable of being fixed or removed on the board.
The board may be made of wood, metal, cork, gutta-percha, agglutinous or any
other suitable material. It is grooved where required in an horizontal direction,
from which grooves the letters &c may be suspended by means of backwardly
projecting pins.
For music the grooves are grouped in fives, or sevens in which case the two
outer grooves are of a different colour, or when only five are used the absence of
auxiliary lines (grooves) is made up for by a proportionate length of the tail of the
note provided with dashes.
The board may be a plain one covered with felt or padding in which the pins at
the back of the type stick.

page_text: Or a plain board covered with agglutinous matter on which the plain types are
stuck, or
A magnetized metal plate with metal types which are attracted to the board by
the magnetism.
On large boards, metal rods may be uses instead of the grooves, on which the
types are hung.
The types are made on any substantial material such as wood, metal, gutta-
percha, card board &c and painted a striking colour so as to show of clearly against
the board. The metal ones are provided with backwardly projecting hooks or pins
to attach them to the board while for the rods the metal is bent into a lip which
rests on the rod.

"
CHARACTERS AND THE LIKE a communication to me from abroad by Clement
Desirè Henri Thureau, Gentleman of N° 11 Rue Berthollet, Paris in the Republic
of France, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
-
The object of this invention is to facilitate the study and teaching of letters,
figures, signs, notes of music, as well as the composition of words (in various types)
and musical passages, and which can be used by the blind.
It consists of
1st A board of suitable size and material for placing the types &c upon.
2nd Moveable types capable of being easily fixed on or removed from the board.
The board preferably rectangular in shape, may be made of wood, metal, gutta-
percha, cork, agglutinous or any other suitable material. It is grooved where
required in an horizontal direction from which grooves the letters &c may be
suspended by means of backwardly projecting pins; or it may be a smooth board
covered with sheet iron in the thickness of which the grooves are formed.
For music the grooves are grouped in fives, or sevens in which case the two
outer grooves are distinguished by different colours or other distinctions sensible to
sight or feeling; or when only five are used the abscence of auxiliary lines (grooves)
is made up for by a proportionate length of tail of the note provided with dashes.
The board may also be a plain one covered with felt or padding in which the
pins at the back of the type stick, or the padding or felt may be stretched on a
frame; or
A plain board covered with agglutinous matter on which plane types are stuck; or
A magnetized metal plate, with metal types which are attracted to the board
by the magnetism.
On large boards metal rods may be used instead of the grooves, on which the
types are hung.
The types are made of any suitable substantial material such as wood metal
cardboard &c painted a striking colour so as to show off clearly against the board.
The metal ones for use with the grooved or padded board are provided with a
sufficient number of backwardly projecting hooks or pins to attach them to the
board, while for the rods the metal is formed into a lip which rests on the rod.

page_text: 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 :-
The above described apparatus consisting of a board with or without grooves to
which, moveable letters, figures, signs or musical characters, provided or not with
suitable pins, hooks, or lips, can be easily attached or detached, in any required
position, or combination substantially as and for the purpose described.
Dated the 23rd day of December 1886.
