AN APPARATUS FOR LEARNING THE ART OF TELEGRAPHY
Year: 1884

page_text: CHARLES KANN Jeweller Twenty One Parker Street Liverpool I do hereby
declare the nature of my invention for AN APPARATUS FOR LEARNING THE ART
OF TELEGRAPHY, to bo as follows:-
An apparatus composed of wood iron or brass, or other material, being a
combination of the key and sounder, and operated upon by means of the lever A,
held in position by supports B and C, which are connected by the small iron rod Ĺ
running through the centre of the lever A, to which is affixed the spring D placed
underneath the lever, and resting on the bed of the apparatus E. The osscillation
of the lever caused by working the button F, causes the two small rivets G and H;
placed at opposite angles on the lever, to rise and fall alternately upon the two irou
plates I and K affixed upon the bed directly underneath the rivets The operator
while thus acquiring the purely mechanical forination of the telegraphic letters,
gradually accustoms the ear to the acoustic sound of same, as produced by the
ordinary telegraph instruments.

page_text: CHARLES KAHN Jeweller 21 Parker Street Liverpool. I do hereby declare the
nature of my invention for AN APPARATUS FOR LEARNING THE ART TELEGRAPHY,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The apparatus is a model of the Single Current Telegraph key instrument and so
arranged as to teach the mechanical movements requisite for the correct formation
of the Telegraphic letters, and also produce the sounds necessary to accustom the
car to sound reading.
Continuing the description of my invention before-mentioned in the preceeding
page and reference being had to the letters of reference on the accompanying
drawing, My invention consists of an apparatus composed of wood, iron brass, or
other material, and operated upon by means of the lover A held in position by the
supports B. and C which are connected by means of the small iron rod L running
through the centre of the lever A and to which is affixed the small spring steel
spring D placed beneath the lever, directly in front of the supports B and C and 1
resting upon the.bed of the apparatus E. The spring (D) serves to cause the lever A
to return to it's original position when the pressure is removed from the button F."
The oscillation which necessarilly follows the working of the button (F) causes the
two small rivets or screw's G and H to rise and fall alternately upon the two iron
plates I and K. placed upon the bed of the apparatus and directly underneath the
the screws G and H, and thereby producing the sounds requisite for teaching the ear.
the sounds of the telegraphic alphebet, as produced by the ordinary instruments.
Continued discription of the invention-The apparatus is a model of the Single
Current Telegraph Key instrument and so arranged as to to teach the mechanical
movements requisite for the correct formation of the Telegraphic letters, and also
produce the sounds necessary to accustom the ear to sound reading.
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
An instrument consisting essentially of the lever or Key and the sound producing 3
devices substantially as and for the purposes hereinbeforo described.
Dated the 12th dov of Sentember 1884.
