Improvements in Type Writing Machines.
We, THE ENGLISH TYPE WRITER LIMITED of 2 Leadenhall Street in the
City of London Manufacturers of Type Writing Machines, and MORGAN DONNE
also of 2 Leadenhall Street aforesaid Manager of the Works of the said Company
do hereby declare the nature of this invention to be as follows:-
The invention relates to improvements in type writing machines and has for its
objects firstly to form and arrange the "hangers" for the type levers in such
manner as to afford broad bearings to the latter, and secondly to provide an efficient
means for adjusting or regulating the length of the connecting rods between the
key levers and the type levers.
In carrying into effect the first part of the invention we form the hangers in the
shape of forks at one end spread out to receive and form broad bearings to the
shafts or axes of the type levers and at the other end contracted to receive
vertical binding screws which pass therethrough and enter corresponding holes
formed in a table shaped like a segment of a circle.
The segmental table is formed with a step or with two tiers of bearing surfaces
arranged at different elevations and the hangers are arranged side by side upon
these bearing surfaces and in order that the type levers may be placed close together
and yet have the advantage of the broad bearings we form the expanded or bearing
ends of the hangers alternately cut away upon their upper and under sides so that
they will overlap one another and thus lie close together at their contracted ends
and we arrange the hangers of the lower tier of the segmental table with their
expanded or bearing ends towards the corresponding ends of the hangers of the
upper tier and we form the contracted ends of alternate hangers of the lower tier
whose bearings for the type levers by the overlapping formation of the hangers
are placed at a lower level than those of adjacent hangers of a reduced height so
as to allow a clear passage for their type levers.
According to the second part of the invention we pivotally mount upon the
inner end of each key lever the lower end of a link which is drilled with a plain
hole from the upper end downwards for a considerable distance to loosely receive
the lower tapped end of a connecting rod which at its upper end is pivotally con-
nected with the cranked end of a type lever and we form a slot in the link in which
works a milled nut which engages the threaded end of the connecting rod and
affords the necessary adjustment thereto and as a further security against accidental
movement of the parts we employ a jam nut which works upon the threaded end of
the connecting rod and takes an abutment against the upper end of the link.

We, THE ENGLISH TYPE WRITER LIMITED of 2 Leadenhall Street in the
City of London Manufacturers of Type Writing Machines and MORGAN DONNE
also of 2 Leadenhall Street aforesaid Manager of the Works of the said Company
do hereby declare the nature of the said invention and in what manner the same is to
be performed to be particularly described and ascertained in and by the following
statement:-
The invention relates to improvements in type writing machines and has for it

page_text: objects firstly to form and arrange the "hangers" for the type levers in such
manner as to afford broad bearings to the latter, and secondly to provide an efficient
means for adjusting or regulating the length of the connecting rods between the
key levers and the type levers.
In carrying into effect the first part of the invention we form the hangers in the
shape of forks at one end spread out to receive and form broad bearings to the
shafts or axes of the type levers and at the other end contracted to receive vertical
binding screws which pass therethrough and enter corresponding holes formed in a
table shaped like a segment of a circle.
The segmental table, is formed with a step or with two tiers of bearing surfaces
arranged at different, elevations and the hangers are arranged side by side upon
these bearing surfaces and in order that the type levers may be placed close
together and yet have the advantage of the broad bearings, we form the expanded
or bearing ends of the hangers alternately cut away upon their upper and under
sides so that they will overlap one another and thus lic close together at their con-
tracted ends, and we arrange the hangers, of the lower tier of the segmental table
with their expanded or bearing ends towards the corresponding ends of the hangers
of the upper tier, and we form the contracted ends of alternate hangers of the
lower tier whose bearings for the type levers by the overlapping formation of the
hangers are placed at a lower level than those of adjacent hangers of a reduced
height so as to allow a clear passage for their type levers."
According to the second part of the invention wé pivotally mount upon the inner
end of each key lever the lower end of a link which is drilled with a plain hole
from the upper end downwards for a considerable distance to loosely receive the
lower tapped end of a connecting rod which at its upper end is pivotally connected
with the cranked end of a type lever and we form a slot in the link in which works
a milled nut which engages the threaded end of the connecting rod and affords the
necessary adjustment thereto, and as a further security against accidental movement
of the parts we employ a jam nut which works upon the threaded end of 'the
connecting rod and takes an abutment against the upper end of the link.
And in order that the said invention may be more clearly understood and readily
carried into effect we will proceed aided by the accompanying drawings more"
fully to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1'is a nÌan mortly in section of so much of a tune writing machine as will

page_text: The hangers be are formed in the shape of forks at one end spread out to form
broad bearings bc to the shafts or axes of the type bars or levers d whilst at
their opposite ends they are contracted and held together by bolts or rivets 62 c² so
as to form apertures 63 to receive vertical binding screws bc which pass through
the apertures and enter corresponding holes formed in the tables a a
respectively, combination washers 6*1 * being interposed between the heads of the
binding screws and the contracted ends of the hangers be
.
“
In order that the type levers d may be placed close together so as to obtain a
compact arrangement of the parts and yet have the advantage of the broad bearings
the expanded or bearing ends 6 of the hangers of the upper tier are formed
alternately cut away at upon their upper and under sides as represented more
particularly at Figures 4, 5 and 6, so that they will overlap one another and
thus lie close together at their contracted ends as shown more clearly at
Figure 1.
The hangers c of the lower tier a² of the segmental table a are arranged with
their expanded or bearing ends c' directed towards the corresponding ends of the
hangers of the upper tier and the contracted ends of alternate hangers c of the
lower tier whose bearings for the type levers by the overlapping formation of
the hangers are placed at a lower level than those of adjacent hangers are formed
of a reduced height as represented more particularly at Figure 9, so as to allow a
clear passage for their type levers d whilst the adjacent or overlapping hangers
are cut away at e' in a similar manner to that described with regard to the upper
tier of hangers and as represented more particularly at Figures 7 and 8, and the
contracted ends of the overlapping hangers of the lower tier are preferably reduced
as represented at es in Figures 7 and 8 with a similar object to that described with
respect to the reduced height of the lower hanger represented at Figure 9.
In carrying out the second part of the invention the type levers d at their upper
ends normally rest against a padded shield d* arranged in the arc of a circle as is
well understood whilst at their lower or cranked ends they are pivotally connected
at d with the upper ends of connecting rods d the lower ends of which are tapped
with a screw thread d2**
Upon the inner end of each key lever e is pivotally mounted at d³* the lower end
of a link which is drilled with a plain vertical hole from the upper end down-
wards for a considerable distance as indicated by the dotted lines in Figures 2 and 3,
so as to loosely receive the lower tapped end d2** of one of the connecting rods d²
whilst a slot ** is formed in the link ³ intersecting the vertical hole * and in
which works a many sided or milled nut which engages the threaded end d2**
of the connecting rod and provides the necessary adjustment between the type
levers d and the key levers e whilst at the same time the rigidity of the connection
between the key levers and type levers is ensured.
As a further security against accidental movement of the parts, a jam nut dis
employed which works upon the threaded end 2** of the connecting rod and
takes an abutment against the upper end of the link d³.
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 :-
1. In a type writing machine the combination of a table having the form of a
segment of a circle and provided with two tiers of bearing surfaces, a number of
type levers provided with prolonged shafts or axes and a number of hangers for the
type levers constructed and arranged in manner substantially as herein shown and
described and for the purpose stated.
2. In a type writing machine the combination with the type levers formed with
cranked ends, the keys levers and the connecting rods formed with threaded ends of
links bored to loosely receive such threaded ends and formed with slots therein
intersecting such bore nuts working in the slots and upon the threaded ends of the
connecting rods and jain nuts also working upon such threaded ends and abutting

page_text: upon the ends of the links substantially as herein shown and described and for the
purpose stated.
