page_text: I, EDMUND JAMES ARNOLD of 3 Briggate, Leeds in the County of York, Stationer,
do hereby declare the nature of this invention, to be as follows:-
The object of my invention is to construct a cheap and simple form of type writer
that can be more readily operated than type writers now in use.
I provide a disc the periphery of which is supplied with type of any required letters,
marks or characters. This disc is fixed on an axle fitted in sliding bearings provided
on a carriage mounted on wheels. The type disc shaft is geared by bevel or other
gearing, so that a rotary motion given to a vertical spindle mounted above it gives a
rotary motion to the horizontal shaft on which the disc is fixed.
For convenience I so arrange the gearing that one half revolution of the vertical
spindle moves the type disc a whole revolution. The whole of the gearing and shaft
carrying the disc are carried on framework suspended on a spring from the carriage,
so arranged that by downward pressure the type disc is brought in contact with the
surface on which the printing is required and leaves the impression of the letters, such
impression being given through an ink tape of ordinary kind. A horizontal dial
plate is mounted on the framework which has on its surface corresponding letters,
marks or characters to those on the type disc, and by turning a pointer attached to the
vertical spindle to any letter on the dial plate simultaneously the type disc is turned
so as to bring the corresponding letter to the bottom, and by depression of the gearing
frame the type disc is carried down and the impression made. The carriage may be
made to travel to give the spaces between the letters, marks or characters by means of
an automatic ratchet arrangement, or ratchet arrangement operated by the band of
the attendant, and may be run or moved across the surface on which the printing
is to take place with or without the assistance of a guide plate or straight edge.

page_text: I, EDMUND JAMES ARNOLD of 3 Briggate, Leeds in the County of York, Stationer,
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 :-
The object of my invention is to construct a cheap and simple form of type writer
that can be more readily operated than type writers now in use.
In the accompanying drawings Fig. 1 is a front elevation, Fig. 2 a transverse
section, and Fig. 3 a plan looking at the top.
I provide a disc A, the periphery of which is supplied with type consisting of any
required letters, marks or characters. The disc A is fixed on an axle B mounted in
sliding bearings C, such sliding bearings being fitted so as to slide freely vertically in
the carriage D, supported on wheels or runners E. The type disc shaft B is geared
by bevel gearing F and spur gearing G, so that a rotary motion given to a vertical
spindle H gives a rotary motion to such horizontal type disc shaft B, and thence to the
type disc A fixed thereon.
For convenience I so arrange the gearing that one half revolution of the vertical
spindle H moves the type disc a whole revolution. The whole of the gearing and
shaft carrying the type disc are carried on framework I attached to the dial plate J,
suspended on the spring K supported on the carriage D, and so arranged that by
downward pressure the type dise A is brought in contact with the surface on which
the printing is required and leaves the impression of the letters, such impression
being given through an inked tape L of ordinary kind. This tape Lis wound from one
bobbin M onto the other bobbin M alternately, motion being transmitted thereto
through vertical rods N, levers O, pawls P and ratchet wheels R, imparted from the
upward movement of the dial plate J. The movement of the tape is reversed by
disengaging one pawl P from its ratchet wheel It and engaging the other, and such tape
in passing from one roller to the other is conducted round the guides S and under the
type disc A as shewn,
The horziontal dial plate J herein before mentioned has on its surface letters, marks
or characters corresponding with those on the periphery of the type disc A, and by
turning a pointer T attached to the vertical spindle H to any letter on the dial plate J,
simultaneously the type disc A is turned so as to bring the corresponding letters to
the bottom, and by a depression of the gearing frame I the type disc A is carried down
and the impression made through the tape L on the surface where such impression
is required.
The carriage may be made to travel to give the spaces between the letters, marks or
characters by means of an automatic ratchet arrangement shewn at U, or ratchet
arrangement operated by hand of the attendant, and may be moved or run across the
surface on which the printing is to take place with or without the assistance of a guide
plate or straight edge.

page_text: The face of the type disc A is grooved in radial lines V opposite each letter, mark
or character, and a small stud W attached to a spring X on the carriage D drops into
each notch V as it comes into the bottom position shewn in drawing, enabling the
operator not only to ascertain when the letter is in its proper position, but also retains
each letter in that position whilst the type disc A is being brought down to make
the impression.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ==
The general arrangement, construction and combination of the various parts forming
the apparatus or machine for type writing, and means employed for operating or
transmitting motion to the same, substantially as herein setforth.
