PROVISIONAL SPECIFICATION.
Improvements in and relating to Movements of Typewriters.
We, HENRY STANBRIDGE, Engineer, and ALFRED AKERS, Gentleman, both of
Cadby Hall Works, West Kensington, London, W., do hereby declare the nature
of this invention to be as follows:-
-
This invention relates to improvements in the system of typewriters, in which
an inverted ink pad and movements are used, such as illustrated by Patent
No. 11862 of 1894 to which we beg leave to refer, and it consists in providing
underneath the therein described U shaped levers of the movement a return or
recoil spring to facilitate its return. The U shaped levers and links are dupli-
cated, so that the type carrying lever is guided centrally.
A circular slotted piece is also arranged on the quadrant in connection with,
and in front of the set of movements so as to serve as a guide to the lever or
type carrying type bar, whilst the type attached thereto is of a uniform width
made to fall between guides consisting of a pair of spherical or other shape
rollers.
This ensures the alignment of the type sideways.
When the movements are all assembled and fixed in place a slot is cut in the
said type carrying lever just behind the type. A plate to correspond and engage
with this slot is fixed on the piece carrying the roller guides and serves as a stop
to prevent the said type carrying lever from shooting forward, should the rivetting
up of the movements get slack, thus ensuring a permanent alignment endways.

We, HENRY STANBRIDGE, Engineer, and ALFRED AKERS, Gentleman, both of
Cadby Hall Works, West Kensington, London, W., 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:-

alignment of the type sideways. When the movements are all assembled and
fixed in place a slot is cut in the said type carrying lever just behind the type.
A plate to correspond and engage with this slot is fixed on the piece carrying the
roller guides and serves as a stop to prevent the said type carrying lever from
shooting forward, should the movement get slack, thus ensuring a permanent
alignment endways.
In the drawings accompanying this specification
Fig. 1 is a side view of the quadrant carrying the movement shewing the same
at rest with type receiving ink, also the movement, in outline resting on the
printing platen.
Fig. 2 is a plan view, part broken, away, of the quadrant, with, one movement
in place in the forward or printing position, the slotted segment of a cicle to
guide type carrying bar and the type guide with rollers is also shewn.
Fig. 3 shews the action of the recoil spring to check the throw of the movement.
Similar letters of reference indicate similar parts throughout.
A is the quadrant.
a' the slots which receive the movement supports.
a tapped holes, the screws of which go to fasten down the movement supports..
B is the movement support.
b₁ the U shaped levers, one on either side of the movement support.
62 are links in uuplicate.

610 recoil spring which acts on the toe of the U levers as shewn in Fig. 3.
C is the type.

the plate to stop the forward throw of main lever and ensure endway
alignment.
G is the printing platen or cylinder.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The combination with a movement as described in Patent No. 11862 of 1894 of
Firstly, A return or recoil spring underneath to check the throw of the
movement.
Secondly. A slotted segment of a circle to act as guide for a part of the
movement.
Thirdly. A central projecting piece with pivots carrying rollers which act
as lateral guides to the type at the printing point.
