I PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane in the County of
Middlesex Fellow of the Institute of Patent Agents do hereby declare the nature of
this invention (a communication to me from abroad by Thomas Hall of 853 Broadway
in the City County and State of New York United States of America) to be as
follows:-
This invention consists of an improved type writing machine which while containing
comparatively few parts is adapted to print a large number of characters. The
machine may be described as consisting of two parts a frame and a travelling
carriage.
The frame carries the printing bar or platen and a suitable index plate which is
carried by arms on a shaft, in which arms are also held a roller, which engaging with
a second roller under the printing platen sorves a means of feeding the sheet of paper.
These rollers are geared together and when actuated by means of a notched wheel,
lever and pawl, will move the paper with a step by step motion over the face of the
platen for the purpose of leaving regular intervals between the lines of printing or
by means of a thumb screw will move it backwards and forwards as desired. To
remove the paper, the roller and index plate are lifted slightly back by thumb pressure
on a lever placed at the end of the frame and operating the shaft.
The travelling frame or carriage moves laterally by means of wheels and guide
rollers upon parallel bars which form part of the framework of the machine. 1
carries a type cylinder and an inking roller which are in a moveable frame, and
consists in the first place of a lower portion carrying the wheels and guide rollers
to it being hinged an upper sloping framework passing directly over the printing
platen.
This frame carries on its upper face a plate bearing printed characters representing
the type available for printing, and below this a perforated plate the holes on which
correspond with the characters on the plate above. Between these two plates is a bar
having hinged at its outer end a handle carrying a pointer which is operated by the
hand and serves to indicate on the upper plate, the letters desired to be printed. The
other end of this har which lies between the index and the perforated plates carries

page_text: a projection which when a letter is indicated by the handle is pressed into a corre-
sponding hole in the perforated plate and serves to hold the type cylinder. 'The
movement of the handle operates a rack-bar connected to it which engages with a cog
wheel and by means of supplementary cog wheels revolves a cylinder upon which are
rubber or other type, and at the same time an inking roller against which the type
press. The type cylinder and inking roller in their moveable frame have also another
movement up and down in the direction of their axes.
Thus the operation of the handle will bring the desired lotter or type over a hole
in a plate which is hinged at the same point as the other parts of the travelling
carriage.
This plate has a flexible rubber portion let into it, through a hole in which the type
may protrude. The pressure upon the handle serves to force the carriage down and
presses the particular type or letter through the hole in this plate upon the paper
lying on the platen below. The pressure upon the carriage is exerted against a spring
which causes it to leave the paper again after printing the letter, when it is caused to
take a step in a lateral direction upon the rails of the framework by hand or by any
other suitable methods. A suitable pointer upon the travelling carriage is provided,
which travels over the index bar on the frame and serves to indicate the place on the
paper where any letter may be printed. The type cylinder is formed of a thin shell
of metal or rubber, or both, having raised characters, and fits upon a suitable cylinder,
while the inking roller is of felt or other suitable material. It will be seen that my
invention consists of a modification or improvement upon the inventions set out in my
specifications No. 827 of 1881 and No. 5737 of 1885.

page_text: A communication from abroad by THOMAS HALL, of 853, Broadway, in the City,
County, and State of New York, United States of America.
I, PHILIP MIDDLETON JUSTICE of 55 and 56 Chancery Lane, in the County of
Middlesex, Fellow of the Institute of Patent Agents, 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 :-
This invention consists of an improved type writing machine which while containing
comparatively few parts is adapted to print a large number of characters.
The machine may be described as consisting of two parts a frame and a travelling
carriage.
The frame carries the printing bar or platen and a suitable index plate which is
carried by arms on a shaft in which arms are also held a roller which engaging with
a second roller under the printing platen serves as a means of fooding the sheets of
paper. These rollors are geared together and when actuated by means of a notched
wheel, lever, and pawl, will move the paper with a step by step motion over the face.
of the platen, for the purpose of leaving regular intervals between the lines of printing,
or by means of a milled wheel, will move it backwards and forwards as desired. To
remove the paper, the roller and index plate are lifted slightly back by thumb pressure
on a lever placed at the end of the frame and operating the shaft.
.
The travelling frame or carriage moves laterally by means of wheels and guide
rollers upon parallel bars which form part of the framo work of the machine.
Said travelling frame carries a type cylinder and an inking roller which are in a
movable frame, and consists in the first place of a lower portion carrying the wheels
and guide rollers, to it being hinged an upper sloping framework passing directly
over the printing platon.
The sloping frame carries on its upper face a plate bearing printed characters
representing the type available for printing, and below this a perforated plate the holes
on which correspond with the characters on the plate above.
Between these two plates is a bar having hinged at its outer end a handle carrying
a pointer which is operated by the hand and serves to indicate on the upper plate the
letters desired to be printed. The other end of this bar which lies between the index
and the perforated plates carries a projection which when a letter is indicated by the
hundle is pressed into a corresponding hole in the perforated plate and serves to hold
the type cylinder. The movement of the handle operates a rack-bar connected to it
which engages with a cog wheel and by means of supplementary cog wheels revolves a
cylinder upon which are rubber or other type, and at the sume time an inking roller
against which the type press. The type, cylinder and inking roller in their moveable
frame have also another movement up and down in the direction of their axes.

page_text: J' is a
a portion of the sheet which is made of thin flexible or clastic material,
preferably india-rubber, and perforated so that one type can protrude.
K and K are rollers between which the paper to be printed is placed; the bearings
of K being in frame A². The position of paper is shown in figure 2.
Kare spur wheels gearing into each other so that the rollers when in contact
must turn together.
K³ is a wheel on end of K by which the rollers are turned.
K' is a plate swinging on shaft of roller K between K³ and A³, to which is
attached K
K' is a lever and pawl combined to act on K³ which drops to position shown in
fig. 6, when not in use.
I is a strip of metal forming a paper holder and index for position of characters
printed, fixed to arms N on shaft O. The bearings of roller K' are in N.
O is a lover on shaft O to separate the rollers which may be pressod together by a
suitable spring.
P is a spring on B¹ bearing up against the middle of bar B³ to support cylinder
away from the paper.
R is a pointor fixed to B¹ to indicate the place of the impression when printing.
To operate the machine -The paper is placed over the platen A' and between the
rollers K K by separating them and the paper holder from the platen by pressing on
lever O¹.
The printing mechanism, consisting of the type cylinder in its frame and the carriage,
is placed at any position on the rails desirable, the position of the type-cylinder being
indicated by pointer R. The handle E is moved to bring the index point to the
desired character on index plate G, thereby moving the type cylinder up or down
lengthwise on bars B and rotating it by the rack and gear D, C³, U2, (, the two
movements combining to bring corresponding character on type cylinder to the
opening in shoot J', and a downward pressure presses the lower pointer of handle
into hole in F, thereby holding the type-cylinder firmly in place, and same
pressure also carrying the whole frame downward, turning on hinge on carriage
at B until the type protruding through J' touches the paper: removing the pressure
the spring P lifts the frame and the same process can be repeated with any other
characters. The rotation of the type cylinder causes the inking roller H which is
saturated with suitable ink to continuously re-ink the typo.
The carriage can be moved along on the rails A' in either direction by hand or
by any of the methods now used for like purpose.
The paper can be moved up or down to any point, by turning the wheel K³;
to move the paper up by regular intervals the lever is used, one movement
being one sixth of a revolution of the rollers, or other regulated proportion.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed as communicated to me by my foreign
correspondent I declare that what I claim is-
1. In a typewriter the frame B hinged under the hand and standing in an inclined
position away from operator, said frame carrying a type cylinder C and at the upper
or further end of frame an index plate, substantially as described.
2. In a type writer the combination with the sliding frame I of the type cylinder (,
adapted to rotate thereon and to be moved longitudinally therewith, substantially as
