PROVISIONAL SPECIFICATION.
Improvements in Type-writers.
I, JAMES SAMUEL FOLEY, Engineer of 65 Gauden Road, Clapham, London,
S.W., do hereby declare the nature of this invention to be as follows:-
This invention relates to the mechanism for operating the type-bars of type-
writers which have the type or type-head carried upon lever arms, usually called
the type-bars.
In carrying out this invention the type bar may be of any ordinary or suitable
construction, pivotted in a suitable frame much in the usual manner, and adapted
to strike either downwards or upwards according to its mode of connection with
the key. The type-bar is preferably provided with a small hole into which fits a
link or other suitable connecting device whose other end engages with an arm or
projection extending from the key. The key itself consists of a round or other
shaped spindle carrying a head in or upon which is the letter or symbol pertaining
to the type carried by the type-bar; from this spindle extends the already
mentioned arm or projection. The quadrant or other frame which carries the type
bars is provided with a slot to each type-bar and in this slot the key projection
works. The slot may be separate from that in which the type-bar is carried or it
may be part of the same. The type-bars may be all pivotted upon the same wire
placed in a groove in the frame and secured by screws. Independent or other
fastenings for the type-bars may however be employed.
Instead of the link which operates the type-bar being connected to a projection
from the key the link itself may if desired carry the projection and be operated
directly by the spindle of the key or projections may be provided on both, or they
may be otherwise suitably connected so as to produce the desired effect.
Instead of the previously described link the key which reciprocates in a straight
line and is not a key lever such as is ordinarily used may carry a straight toothed
rack engaging with teeth upon or in connection with the type-bar, and thus produce
the desired movement.

Improvements in Type-writers.
I, JAMES SAMUEL FOLEY, Engineer, of 65 Gauden Road, Clapham, London,
S.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 :—
This invention relates to the mechanism for operating the type-bars of type-
writers which have the type or type head carried upon lever arms, usually called
the type-bars.
In carrying out this invention the type-bar may be of any ordinary or suitable
construction, pivotted to a suitable frame much in the usual manner, and adapted
to strike either downwards or upwards according to its mode of connection with
the key. The type-bar is preferably provided with a small hole into which fits a

page_text: link or other suitable connecting device whose other end engages with an arm or
projection extending from the key. The key itself consists of a round or other
shaped spindle carrying a head in or upon which is the letter or symbol pertaining
to the type carried by the type-bar; from this spindle extends the already
mentioned arm or projection. The quadrant or other frame which carries the type-
bars is provided with a slot to each type-bar and in this slot the key projection
works. The slot may be separate from that in which the type-bar is carried or it
may be part of the same. The type-bars may be all pivotted upon the same wire
placed in a groove in the frame and secured by screws. Independent or other
fastenings for the type-bars may however be employed.
The accompanying drawing represents in side view a key and type-bar and their
connections.
suitable
A is the type-bar of any convenient construction and carrying any
arrangement of type; this is pivotted at A¹ in any suitable framing B having the
required provision for receiving the type-bars. A convenient arrangement is to
form a segmental frame C provided with any required number of grooves or
recesses Cin which the type levers are placed being preferably carried upon a
long curved wire A' carried in a groove C³ in the top of the frame. The key D
forms a part of or is secured to a circular or other spindle E carried in the frame-
work and normally maintained in its highest position by a helical spring F coiled.
round the spindle as clearly shown in the drawing. An arm G of any required
length projects from the key and spindle D and E through the groove C' in the
frame and is connected by a link H of any suitable description with the type-
bar A which is preferably extended at A so as to enable the link H to be
connected with the bar a sufficient distance in front of the pivot A'. As the key D
is pushed down the arm G through the link H pulls down the type-bar until it
assumes the horizontal or other required position shown in dotted lines in the
drawing, the link H allowing for the necessary accommodation between the
rectilinear reciprocating motion of the arm G and the angular or swinging motion
of the bar A about its pivot A'.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;-
1. In a key and type-bar mechanism for typewriting machines the combination
with a pivotted type-bar A working radially about its pivot of a reciprocating key
such as D E arm G and link H substantially as described and illustrated in the
accompanying drawing.
2. In a key and type-bar mechanism for typewriting machines the combination
with a pivotted type-bar and reciprocating arm G of a frame having slots or
openings such as Cin which the type-bar A rotates and the arm G reciprocates
substantially as described and illustrated in the accompanying drawing.
3. In a key and type-bar mechanism for typewriting machines the combination
with a type-bar such as A pivctted behind the axial line of the bar of a link such
as H jointed to the bar in front of the axial line and connecting it with the key or
the key arm to which is imparted a plain reciprocating motion substantially as
described and illustrated in the accompanying drawing.
4. The combination and arrangement of parts constituting the complete key and
type-bar mechanism substantially as described and illustrated in the accompanying
drawing.
