PROVISIONAL SPECIFICATION.
Improvements in or relating to Typewriting Machines.
We, JAMES SAMUEL FOLEY of 5 Clifton Villas High Street, West
Bromwich, County of Stafford, Engineer, and GEORGE SALTER of Steam
Gauge and Spring Works, West Bromwich aforesaid, Manufacturer, do hereby
declare the nature of this invention to be as follows:-
This invention relates to typewriting machines the three portions which we are
improving being the line spacing mechanism, the means for holding the paper to
the roller and the feed of the inking ribbon.
The line spacing is effected in the following manner-To the end plate of the
paper carriage we secure preferably by rivetting an arm with thumb plate, and
around the spindle of the paper roller we place a preferably circular plate or disc
with an arm and a finger plate. Projecting from the disc is a stud adapted to
reciprocate in a circular groove in a link held in one end by the head of the stud
and at the other by a small stud projecting from the fixed thumb plate arm and
entering one of a series of holes in the link so that the extent of the movement or
travel of the finger plate arm is regulated according to the position of the link
upon the thumb plate arm and a pawl which is carried by the finger plate arm,
engages with one or more of the teeth of a toothed wheel upon the end of the
paper roller according to the extent of the movement of the arm which carries it.
If preferred the link may carry the stud to engage the corresponding holes in the
fixed arm.
The devices for holding the paper to the roller consist of conveniently two
springs connected in any convenient manner with the paper carriage, and shaped
to and bearing upon the periphery of the paper roller. This spring may be moved
to any desired positions upon the roller so that papers of various sizes can be
accommodated. Instead of springs rigid plates may be used, but we prefer the
springs. These springs may be made detachable and a convenient arrangement is
to secure them upon the paper scale upon which they slide as required; bolt heads
or similar projections would be in the way of the operator or of the paper, and we
avoid them by the construction described.
The ribbon feed is effected by a pinion which rotates always in the same
direction, and may be rotated in any convenient manner, preferably directly from
the spring which operates the paper carriage. In order to engage this pinion with
whichever one of the ribbon spools may be required, we carry the latter in or upon
a suitable pivotted frame adapted to rock or oscillate so as to alternately engage
the spools upon each of which has a toothed wheel or periphery to gear with the
pinion. The pinion lies between these two wheels and whichever spool the pinion
is engaged with is operated by it, so as to wind the ribbon on to that spool and off
the other one.
To change the position of the oscillating plate and thereby remove one spool
from engagement with the pinion, and place the other into engagement therewith,
we may employ any suitable device but conveniently a shaft carries an eccentric,
which engages with the face of the oscillating plate, thus turning it from one
position to the other as the eccentric is turned; the end of the eccentric shaft may
project at the front of the typewriter and carry a milled disc or head by which it

page_text: can be turned, and any convenient means may be employed for securing it in either
of its positions should that be necessary.
Each spool is preferably carried pivotted upon a spindle having bearings in the
oscillating plate and a bridge fixed thereon, and so arranged that by turning a
screw the pressure upon the spool or spindle can be increased or diminished and
the tension of the ribbon thereby adjusted.

Improvements in or relating to Typewriting Machines.
We, JAMES SAMUEL FOLEY, of 5 Clifton Villas, High Street, West
Bromwich, County of Stafford, Engineer, aud, GEORGE SALTER, of Steam
Gauge and Spring Works, West Bromwich aforesaid, Manufacturer, 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 typewriting machines, the three portions which we are
improving being the line spacing mechanism, the means for holding the paper to
the roller and the feed of the inking ribbon.
The line spacing is effected in the following manner :-To the end plate of the
paper carriage we secure, preferably by rivetting, an arm with thumb plate, and
around the spindle of the paper roller we place a preferably circular plate or disc
with an arm and a finger plate. Projecting from the disc is a stud adapted to
reciprocate in a segmental groove in a link held at one end by the head of the stud
and at the other by a small stud projecting from the fixed thumb-plate arm and
entering one of a series of holes in the link so that the extent of the movement or
travel of the finger plate arm is regulated according to the position of the link
upon the thumb plate arm, and a pawl which is carried by the finger plate arm
engages with one or more of the teeth of a toothed wheel upon the end of the
paper roller according to the extent of the movement of the arm which carries it.
If preferred the link may carry the stud to engage the corresponding holes in the
fixed arm.
As a further alternative the link instead of being slotted can have serrations at
different distances from a pivot by which latter it is connected to the paper
carriage, the link being adjustable to bring one or other of these serrations into
the path of the finger plate arm or a projection therefrom so that the limit of the
extent of travel of the same can be varied as desired.
The devices for holding the paper to the roller consist of conveniently two
springs connected with the paper carriage, and shaped to the periphery of the
paper roller on which they may bear. Each spring may be moved to any desired
position upon the roller so that papers of various sizes may be accommodated.
Instead of springs rigid plates can be used, but we prefer the springs. These
springs may be made detachable and a convenient arrangement is to secure them
upon the paper scale upon which they slide as required; bolt heads or similar
projections would be in the way of the operator or of the paper, and we avoid them
by the construction described.
The ribbon feed is effected by a pinion which rotates always in the same
direction, and may be rotated in any convenient manner, preferably directly from
the spring which operates the paper carriage. In order to engage this pinion with
whichever one of the ribbon spools may be required, we carry the latter in or upor

page_text: a suitable pivotted frame adapted to rock or oscillate so as to alternately engage
the spools upon each of which has a toothed wheel or periphery to gear with the
pinion. The piniou lies between these two wheels and whichever spool the pinion
is engaged with is operated by it, so as to wind the ribbon on to that spool and off
the other one.
To change the position of the oscillating plate and thereby remove one spool
from engagement with the pinion, and place the other into engagement therewith,
we may employ any suitable device but conveniently a shaft carries an eccentric,
which engages with the face of the oscillating plate, thus turning it from one
position to the other as the eccentric is turned; the end of the eccentric shaft may
project at the front of the typewriter and carry a milled disc or head by which it
can be turned, and any convenient means may be employed for securing it in either
of its positions should that be necessary.
Each spool is preferably carried pivotted upon a spindle having bearings in the
oscillating plate and a bridge fixed thereon, and so arranged that by turning a
screw the pressure upon the spool or spindle can be increased or diminished and
the tension of the ribbon thereby adjusted.
In the accompanying drawings,
Figures 1 and 2 are perspective views comprising portions of a paper carriage
and the adjacent mechanism, and illustrating two constructions of line spacing
apparatus according to this invention;
Figure 3 is a perspective view showing two springs constituting movable elastic
guides for the paper, self-secured upon the paper scale;
Figure 4 is a perspective view of portions of a typewriter comprising the
moving frame for the ribbon spools, and its appurtenances;
Fig. 5 is a vertical section on the line of the shaft L' of Fig. 4.
Like letters indicate like parts throughout the drawings.
With reference first to Figure 1, A is a paper carriage upon which is fixed an
arm A'; B is the paper roller and B' the spindle of the same; C is a circular
plate which is arranged to oscillate upon the spindle B' and is provided with a
pawl C' pivotted upon it and provided with a handle C2. A projection C³ extends
from the plate C. D is a link connected to the arm A' at one end, and provided
at its other end with a segmental slot D¹ or a groove into which extends the
projection C3 from the circular plate C, so that the oscillation of the circular
plate C will be limited inasmuch as the projection C³ cannot pass beyond the end
of the slot D'. It is the outermost end of the slot D' (that is to say the end
farthest from the point at which the liuk D is connected to the carriage) which
limits the movement of the plate C in that direction, its movement in the opposite
direction being limited by means not forming part of the subject matter of the
present invention.
D are holes in the link D' and A2 is a stud projecting from the arm A' and
adapted to engage in one or other of these holes to retain the link D in position
upon the carriage. By shifting the link to bring the different holes D2 iuto
engagement with the stud A2 the outer end of the slot D' is adjustable to different
distances from the point at which the link is attached to the carriage and corre-
spondingly limits the movement of the plate C, which in turn limits the feed
imparted to the paper roller A by the pawl C.
Alternatively the series of holes D2 may be in the plate A¹ and the projection A²
may be on the lever D at the opposite end to that at which the slot is provided.
As a further alternative the link D need not be slotted but may instead, as shown
in Figure 2, be pivotted at D to that plate A' and provided with teeth D D D
at its free end at different levels and at different distances from the pivot and so
disposed that when the tooth D is in a position in which it will obstruct the path
of the projection C the teeth D & D are out of the path thereof. Similarly
when the tooth D' is brought into the path of the projection the tooth D' is out of
that path and so on, the angular adjustments of the link D about its pivot serving
to bring one or other of these teeth into the operative position in accordance with

page_text: the desired limitation of the movement of the projection C. The link D in this
example moves sufficiently stiffly on its pivot to retain any angular position to
which it may be adjusted.
With reference now to Figure 3 in which certain parts are shown broken away
for the sake of clearness, E is the paper scale in proximity to the paper roller B;
in the present example it is of angular form in cross section.
Fare elastic guides self-secured upon the scale E;, that is to say each one is
made of spring steel in the form shown, shaped to engage with the flange E¹ of the
scale E as shown and bent or slightly curved as at F1 to press with sufficient
force upon the other flange of the scale to produce friction enough to retain the
guide in the position into which it is adjusted, whilst enabling it to be slidden
along the scale as may be desired, there being no bolts, nuts or fastening to secure
the guides in position. Each guide is bent as at F to touch or lie close to the
periphery of the roller B.
If for the elastic guides F rigid ones can be substituted; they may be of
equivalent forin and should fit sufficiently tightly upon the scale F or to the paper
carriage C to prevent them from being accidentally moved.
With reference now to Figures 4 & 5 G is a pinion which is rotated always in
one direction by any convenient means. H is a frame pivotted at H¹ to the main
frame J of the machine and carrying the two ribbon spools K. Each spool K
has a spur wheel K¹ fixed to and forming part of it, and the two spools are so
disposed that only one spur wheel can engage with the pinion G at a time. The
spools are disposed at opposite sides of the pinion G so that by moving the
frame H upon its pivot in either direction one of the spur wheels K¹ is brought
into gear with the pinion G and the other taken out of gear therewith. The
spool K which is at any time out of gear with the pinion G is operated through
the medium of the ink ribbon by its companion spool and the ribbon K2 is so
disposed that each spool when operated by the ribbon shall run in a direction the
reverse of that which it would turn in if operated by the pinion G directly.
With the frame in the position in which it is shown in the drawings the move-
ment of the pinion ribbon spool and ribbon is in the directions indicated by the
arrow in proximity to each; but if the frame be moved over to take out of gear
with the pinion G the spur wheel which is now shown as engaged with it and
put the other spur wheel K into gear with it the parts will move in the
directions reverse to those indicated by the arrows, with the exception of the
pinion G which as aforesaid rotates always in one direction.
The frame is oscillated for the purpose of changing the direction of the
movement of the ribbon by the eccentric L fixed upon the shaft L' pivotted in
the main frame H2 of the machine and extending to the exterior thereof at which
is a inilled head L by 'which it can be easily rotated.
The sheave of the eccentric between the parallel faces of parts M³ of the
oscillating frame H (Fig. 4); when rotated by the shaft L¹ it moves the frame
from side to side.
Hare bridges fixed at their upper parts to the frame H and each receiving
at its lower end one end of the spindle of the spool M in immediate proximity
thereto. M is a tightening screw passed through each bridge into the frame H
as shown so that it can be screwed up to move the free or lower end of the
bridge inwards to increase as desired the pressure upon the end of the spool
spindle and so reciprocate the tension of the ribbon.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In a typewriting machine the combination with the carriage A and an
oscillating support for a pawl, of a slotted link such as D connected to the
carriage and engaged with the support C, and means whereby the slotted portion
is adjustable substantially as and for the purpose specified.
