hereby declare the nature of my said invention to be as follows:-
The object of this invention is to provide an inexpensive yet perfect Type writer
of very few parts and simple construction which can be used by being simply placed
on the paper and thus obviating the necessity of having either specially prepared
paper or attaching it to a roller or other carrier.
For this purpose I provide a bedplate preferably a metal casting of suitable
form having at the upper side a bearing or bearings for the travelling carriage
and at the lower side a space of such size as may suit the paper to be used,
the travelling carriage is provided with guides in or on which works a slide or arm
that carries the Type wheel This Type wheel may be mounted either obliquely
vertically or in any other position and carries the Type (that may be made of any
material preferably india rubber) on its periphery On the face of this wheel are index
letters corresponding to the Type with a pointer to indicate the letter to be used-The
carriage is moved along by means of a bar or rack attached to the bed plate and a
pinion working in samo this pinion is actuated by the printing movement of the Type
wheel the requisite distance for a fresh letter being provided by means of a racket and
pawl the latter being connected by an arm to the slide carrying the Type wheel or this
feed movement may be produced by a system of levers or wedge movement the space
between the words will be found preferably by pressing the Type wheel down twice
without touching the paper thus giving the space as equal to two letters-On the
completion of a line of printing the carriage is simply moved back again to commence
a fresh one the pinion being thrown out of gear for the purpose by pressing. the
Thumb lever carrying the same at the same time the machine is moved down the
paper a sufficient distance to suit the position of the next line The inking may be
performed either by roller pad or other ordinary means a variable feed proportioned
to the width of the letter can be given by forming projections on the Type wheel in
the manner of a cam the height of projection giving the length of feed communication
being made between cams and rachet wheel by means of intermediate levers.

I GEORGE ROYLE of 31 Comeragh Road, West Kensington, S.W. London
Gentleman 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 this invention is to provide an inexpensive yet perfect Type writer of
very few parts and simple construction, which can be used by being simply placed on
the paper, and thus obviating the necessity of having either specially prepared paper,
or attaching it to a roller or other carrier.
For this purpose I provide a bed plate preferably a metal casting of suitable form
having suitable bearings or runners for the travelling carriage-The Travelling
carriage is provided with guides in or on which works a slide or arm that carries the
Type wheel This Type wheel may be mounted either obliquely vertically or in any
other position and carries the Type (that may be made of any material, preferably
India rubber) on its periphery, on the face of this wheel, or on an index separate from
it are letters corresponding to the Type, with a pointer or pointers to indicate
the letters to be used. The carriage is moved along by means of a bar or rack
attached to the bed plate, and a pinion working in same this pinion is actuated by the
printing movement of the Type wheel, the requisite distance for a fresh letter being
provided by means of a rachet and pawl, the latter being connected to the slide
carrying the Type wheel, or this feed movement may be produced by a system of
levers or wedge movement, the space between the words will be formed preferably by
pressing the Type wheel down twice without touching the paper, thus giving the space
equal to two letters, on the completion of a line of printing the carriage is simply
moved back again to commence a fresh one, the pinion being thrown out of gear for
the purpose by pressing the thumb lever carrying the same, at the same time the
machine is moved down the paper a sufficient distance to suit the position of the next
line the inking may be performed either by roller, pad, or other ordinary means, a
variable feed proportioned to the width of the letter can be given by forming pro-
jections on the Type wheel in the manner of a cam, the height of projection giving
the length of feed, communication being made between cam and rachet wheel by
means of intermediate levers guides may be part of or attached to the bed plate for
the purpose of regulating the width and distance of the lines.
In order that my invention may be more clearly understood and readily carried
into effect I will proceed aided by the accompanying drawings more fully to describe
the same.

In figures 1. 2. 3. 4. a represents the bed of the machine which is shewn as built up
in parts but may be made in one casting, with lugs at a* to carry rack c. d represents
two rods upon which travel the saddle to be hereinafter described, that portion of the
bed plate at a✶✶ is so formed that it shall hold down the paper to be printed on, and
is bevilled on the under side to prevent its coming into contact with the printed line

page_text: proper space between the lines, and if required it may be made to slide so as to vary
the distance between such lines, and on its upper surface there may be drawn a scale
as guide for the carriage commencing and ending each line. The saddle e in figs. 1. 2.
3. 4. 5. 6 is a casting of any suitable shape with flanges e on each side through
which, holes are bored to allow it to run easily on rods d the front side has also a
flange e to carry the pins for the blotting preventer, on the same flange at fa
small triangular projection is formed which acts as a guide for the Type wheel when
in the act of printing, attached to this saddle are two upright rods g in figs. 2. 3. 4.
5. 6 on which the slide h carrying the Type wheel is free to move up and down,
these rods are connected and kept in a parallel position by the bridge i in figs. 1. 2.
3. 4. the ends of this bridge are prolonged to carry the semi circular index k in
figs. 1. 2. 3. 4 the slide h in figs. 1. 2. 3. 5 is formed with flanges * top and bottom
through which holes are bored to run on the uprights g in a similar manner to the
saddle ou bars d. The front of this slide has a slight projection or chipping piece
surfaced for boss of Type wheel to work against, to the side flange of this slide is
attached the pawl m in figs. 4. 5 with spring n to keep the same to its work and small
stop at o to keep it in position, the slide is brought back to its position after a letter
has been printed, by the spring p. in figs. 2. 3. 4. 5 this spring being attached to the
saddle e and the free end working under the small lug on slide h in figs. 3. 5, the
feed motion shewn in figs. 2. 3. 4. 5 is formed by a bearing A carrying a spindle B at
the outer end of which is a pinion C and at the inner end a rachet wheel D actuated
by the pawl m this bearing is carried by a forked casting E secured to the saddle e the
bearing being jointed in the forked portion by a pin shewn at E*, at A* is a small
lip to which a set screw works to regulate the pitch of the pinion in the rack, the
outer end of the bearing is prolonged as a thumb plate A** figs. 4. 5, the bearing
being hold in position so as to keep the pinion in gear by the spring F fig. 5. which
is secured to the saddle e, the Type wheel G in figs. 1. 2. 3 4. 6. is formed with a
groove round the edge to receive the type H one half of the face of the wheel is
painted black and the other half white one half being for capitals and numerals and
the other half for small Type and stops; for convenience these words being painted in
the places as shewn in fig. 1, the two index pointers K in figs. 1. 2. 3 being attached
to the wheel as shewn in their respective halves, a handle L figs. 1. 2. 3. 4 being
affixed to the face in any ordinary manner, the back of this wheel has a projecting
rim G* with triangular indentations formed in same in position to suit the respective
letters and to slide on guide fa flanged spindle M figs. 3. 5 is attached to the slide h
on which the Type wheel revolves this spindle being screwed up to a shoulder, the
Type wheel always works accurately against the chipping piece in front of slide / the
index K is preferably shaped so as to cover and protect the Type and on its face is
marked with the necessary characters corresponding with the Type on the wheel and
so placed that on either pointer being brought opposite one of these characters the
corresponding type will be in its proper position for printing, the inking arrangement
is formed by a disc R figs. 1. 2. 4 faced with felt or other suitable material to receive
the ink, this disc revolves on a spindle attached to the slide and is kept against the
type by a spiral spring acting against its outer side, the blotting preventer S in fig. 1
is formed of very thin metal secured to a pin attached to the saddle e at one end and
free to work on a similar pin at the other end, it is curved to such a radius as will
ensure its just leaving the paper after the printing of each letter, a small opening
being left, to allow only the character required to be printed and thus prevent blotting
from the type on each side of it.
The machine is thus worked it is placed on the paper to be printed on in a proper
position to commence the first line, the wheel is then turned bringing the white or
black part uppermost according to the type required, in the act of turning the type is
inked by contact with the revolving disc, the pointer is then brought to the letter
required and the wheel pressed down, thereby printing the letter on the paper the
corresponding notch at the back of Type wheel being engaged with guide in front of
saddle, thus ensuring the correct position of each letter, on the descent of the wheel
the pawl slips over a certain number of teeth of the rachet wheel and on its rising

page_text: feeds the rachet wheel carrying with it the pinion on other end of the same spindle
working in fixed rack advances the entire carriage with Type wheel the space of one
letter, on the completion of a word the wheel is depressed twice not sufficiently to
touch the paper thereby advancing it the width of two letters for space between the
words on completion of the line the thumb lever is depressed and the carriage pushed
back to its starting point and the machine brought forward the width of a line by
placing the guide a** in a line with the completed line of printing.
