[A communication to him from abroad by Josiah. L. Young, of Tarrytown, New
York, United States of America,]
This Invention relates to a type-writer so constructed that the operation is
performed by moving a wheel or segment of a wheel, with raised letters or
characters on its edge, over the surface of the paper. Over this, wheel or segment.
is an index-wheel upon which are placed the letters or characters corresponding to
those on the type-wheel; these wheels are connected by a bevel gear wheel and are
moved together by an arm which is pivotted to the centre of the index-wheel; the
outer edge of said wheel is provided with projections or notches with spaces
between; these spaces are numbered or lettered the same as the numbers or letters
on the type-wheel; by moving this arm to the letter desired on the index wheel
and carrying it around to the delivery post, then pressing down the lever on which
the type-wheel and index wheel are placed, the desired letter is printed or
impressed on the paper.
In carrying the said Invention into practice I provide a frame and there is a
guide strip or track extending across the said frame; this guide strip is raised a
little above the surface of the frame to allow the paper which rests on the frame to
pass or move under it. The sides of said frame are grooved and the ends of the
guide strip are tongued so that the guide strip may be moved to any desired
longitudinal position on the frame.

page_text: Upon the guide strip is placed a carriage. This carriage moves along the guide-
board at regular spaces. These spaces or distances are regulated by a ratchet and
pawl (or its equivalent) which catches into one of a line of perforations on the
guide strip; when the ratchet is pressed the pawl catching in the perforations
produces a leverage which forces the carriage to the next hole or perforation;
when this movement of the carriage is made a lever is lifted above the paper; by
repeating the pressure the carriage may be moved to any space or perforation on
the guide strip. These perforations are at exact distances apart.
A rack or other appropriate equivalent might be employed to move the carriage.
The lever is pivotted to the carriage at its outer end and perpendicular to its die is
fixed the type wheel; the alphabet or symbols are raised upon the edge of this
wheel or disc.
On the top of the lever and at right angles to the type wheel is placed the index
wheel or disc; the edge of this wheel is turned upwards or vertical from its plane,
and is divided into projections and spaces; these spaces are equal to the letters on
the type wheel and correspond with them.
By means of bevel gear wheels or other connection the type wheel and index
wheel move together so that the chosen letter on the index wheel is printed on the
paper by the type wheel. An arm is pivotted in the centre of the index wheel or
disc and is jointed so as to be easily lifted above the projections and spaces and can
be moved around the disc in either direction.
In operating the machine the movable arm is placed in the space marked by the
letter desired to be printed; this arm is stopped at a fixed post; this post is
provided with a slot into which the arm drops. The lever is then pressed
downward at the printing end and the letter delivered upon the paper; the arm is
again moved to the space desired and brought around to the fixed post, bringing or
revolving the disc as before, which in turn by the agency of the bevel gear wheels
also revolves the type wheel. The lever is again pressed upon the paper and the
printing performed as before.
After printing a letter the pressure of the hand on lever is slightly relaxed,
which allows a spring or its equivalent to lift the printing end of the lever above
the surface of the paper, as it lifts, the ratchet is operated which instantly carries
the carriage to the next required space by means of the pawl catching into the
hole or perforation on the guide strip. A roller supplies the type wheel with the
printers ink or its equivalent.
There are feed rollers on the top of the frame used to carry the paper
longitudinally from line to line. One of these rollers is placed flush with the top
surface or plane of the frame. The other is placed above it in appropriate position;
the upper roller is covered or supplied with bands of rubber or other equivalent to
facilitate the feeding of the paper. I also use rollers as a clamp to hold the paper
in position when I use the grooves to change the position of the guide strip.

HENRY HARRIS LAKE, of the firm of Haseltine Lake, & C° Patent Agents,
Southampton Buildings, London "IMPROVEMENTS IN TYPE-WRITING MACHINES."-
A communication to me from abroad by Josiah L. Young, of Tarrytown, New
York, United States of America
:
This Invention relates to a type-writer so constructed that the operation is
performed by moving a wheel, or segment of a wheel, with raised letters or
characters on its edge, over the surface of the paper. Over this wheel or segment,.
is an index-wheel upon which are placed the letters or characters corresponding to
those on the type-wheel. These wheels are connected by a bevel gear-wheel and
are moved together by an arm which is pivotted to the centre of the index-wheel.
The outer edge of said wheel is provided with projections or notches with spaces
between; these spaces are numbered or lettered the same as the numbers or letters.
on the type-wheel By moving the said arm to the letter desired on the index-
wheel and carrying it around to the delivery post, then pressing down the lever
on which the type-wheel and index wheel are placed, the desired letter is printed
or impressed on the paper
In the accompanying Drawing
Figure 1 is a longitudinal view partly in section of a type writer constructed
according to this Invention
Figure 2 is an end elevation of the same partly in section and
Figure 3 is a top view
Similar letters of reference indicate corresponding parts in the several figures.
A indicates the frame and B a guide strip or track extending across the frame.
This guide strip is raised a little above the surface of the frame to allow the
paper C, which rests on frame A, to pass or move under it. The sides of the said
frame are provided with grooves D and the ends of the guide strip are tongued
so that the guide strip may be moved to any desired longitudinal position on the
frame A. Upon the guide strip B is placed a carriage E which moves along the
guide-board B at regular distances regulated by a ratchet and pawl F (or its
equivalent) which engages with one of a line of perforations G on the guide strip B.
When the ratchet F is pressed, the pawl catching in one of the perforations.
produces a leverage which forces the carriage E to the next hole or perforation ;
when this movement of the carriage is made the lever H is lifted above the paper;
by repeating the pressure the carriage E may be moved to any space or
perforation on the guide strip B. These perforations are at exact distances
apart. A rack or other appropriate equivalent might be employed to move the
carriage.
H indicates a lever pivotted at I to the carriage E at its outer end, and
perpendicular to its side is fixed the type wheel J; the alphabet or symbols are
raised upon the edge of this wheel or disc.
On the top of the lever H, and at right angles to the type-wheel, is placed the
index wheel or disc K; the edge of which is turned upwards or vertical from its
plane, and is divided into projections and spaces a, a'; which are equal to the letters
on the type-wheel and correspond with them. By means of bevel gear wheels L
and L or other connection, the type wheel and index wheel move together so that
the desired letter on the index wheel K, is printed on the paper C by type wheel J.
The arm M is pivotted in the centre of the index wheel or disc and is jointed so
as to be easily lifted above the projections and spaces a, a¹, and can be moved
around the disc in either direction

page_text: In operating the machine the movable arm M is placed in the space marked by
the letter desired to be printed, and is stopped at a fixed post N, which is provided
with a slot O, into which the arm M drops. The lever H is then pressed
downward at the printing end and the letter delivered upon the paper; and the
arm M is again moved to the space desired and brought around to the fixed post N,
bringing or revolving the disc as before, which in turn, through the agency of
the bevel gear-wheels, also revolves the type wheel. The lever H is then again
pressed upon the paper and the printing performed as before.
After printing a letter the pressure of the hand on lever H, is slightly relaxed,
which allows spring P, or its equivalent, to lift the printing end of lever H above
the surface of the paper; as it lifts the ratchet F, is operated, which instantly
carries the carriage E to the next required space by means of the pawl Q, Figure 2,
catching into a hole or perforation G, on the guide strip B. The roller S, supplies
the type-wheel with printers' ink or its equivalent.
R and R2 indicate feed rollers on the top of frame A, used to carry the paper
longitudinally from line to line. One of these rollers R2 is placed flush with the
top surface or plane of the frame A. The other, R, is placed above it in appropriate
position; the upper roller is covered or supplied with bands of india-rubber or
other equivalent to facilitate the feeding of the paper. I also use rollers R, R² as
a clamp to hold the paper in position when I use the grooves D, to change the
position of the guide strip B.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim
First In a type-writer, the guide-strip B in combination with the carriage E,
the type wheel J, the index-disc K, the arm M, the post N with its notch O and
the bevel gear wheels L, L2, substantially as described
