page_text: 1, JAMES SAMUEL FOLEY of 5 Clifton Villas, High Street West Bromwich, in
the County of Stafford, Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to the ribbon shield or bracket which carries the ribbon
and spools in a type writing machine and may be formed of a flat plate bent near
the centre of its length at right angles, one portion being worked off to nearly a
point and provided with a suitable number of, conveniently two, slots through
which the ribbon can be drawn while another portion of the plate may be cut away
to facilitate the passage of the type and type heads; the extreme end of the plate
may be pointed as an index to indicate by a scale carried by the paper carriage the
position of the latter. The ribbon after passing through the previously-mentioned
slots may be carried round a wire suitable yoke or equivalent fixed preferably near
the bend in the plate and then passes down, one end to each of two independent
spools or reels pivotted upon the plate so that their pivots lie parallel to the top or
visible portion of the plate. Pirotted upon the plate near the bend is a two-armed
spring so arranged that one arm presses upon the roll of ribbon upon each reel by
which arrangement the spring automatically adjusts itself to the varying diameters
of the rolls of ribbon when the ribbon is rolled off one roll and on to the other in
the working of the machine, the pressure being the same in all cases.
The plate
may be provided with a pin or equivalent fitting into a hole in a suitable standard
or projecting portion of the framework in which it may be gripped by a set screw
or the like a flat being preferably formed on the pin so that when the set screw is
tightened up the whole plate necessarily takes its proper position. This positioning
may however be effected by other means such for example as a second pin or a
portion of the plate engaging with a corresponding portion of the support.
Each of the ribbon spools or reels is provided with a toothed disc ring or
equivalent placed upon opposite sides of the reels; these engage with the teeth of
a pinion carried upon a spindle rotated as the carriage of the machine travels the
pinion being free to travel upon the spindle or preferably the whole spindle being
arranged to travel longitudinally carrying the pinion with it so that the latter may
engage alternately with either of the toothed ribbon spools. The spindle may be
provided with peripheral grooves with which would engage a projection upon a
suitable plate spring or equivalent which thus serves the double purpose of securing
the spindle and consequently the pinion in its proper position in engagement with
one of the ribbon spools and also provides the necessary friction to prevent the
spindle from slipping excepting when moved in the course of the operation of the
machine.
A convenient means of rotating the spindle and pinion is to have a ratchet wheel
at one end of the spindle engaging with a suitable spring pawl upon or in connection
with the spring barrel which drives the paper carriage so that as this spring barrel
rotates the pawl carries the ratchet wheel round with it while the spindle can be
turned in the other direction at any time by hand if required for winding up the

page_text: ribbon or for other purposes. The spindle preferably projects at the front of the
machine but it carries a milled head by which it may be pulled and turned.

I, JAMES SAMUEL FOLEY of 5 Clifton Villas, High Street, West Bromwich,
in the County of Stafford, Engineer, 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 ribbon shield or bracket which carries the ink-ribbon
and spools in a type writing machine, to various appurtenances thereof, and to
driving-apparatus for the ink-ribbon.
In the accompanying drawings
Fig. 1 is a plan of one construction of my improved ribbon shield or bracket and
of parts of the type-writer adjacent thereto.
Fig. 2 is section on the line 2, 2 of Fig. 1.
Fig. 3 is an elevation of the same apparatus, viewed in the direction of the arrow
of Fig. 2, certain parts being removed for the sake of clearness.
Fig. 4 is perspective view of details hereinafter referred to.
Like letters indicate like parts throughout the drawings.
In the example illustrated the bracket A which might be a skeleton or frame if
desired is formed of a flat plate bent near the centre of its length at right angles,
one portion A¹ serving as a ribbon-extending device being worked off to nearly a
point and provided with two slots A 2 A 3 through which the ink-ribbon B can be
drawn, and a spring A 4 to aid in guiding the ribbon, while another portion of the
plate is cut away at A5 to facilitate the passage of the type and type heads;
further the extreme end A 6 of the plate is pointed as an index to indicate by a
scale C carried by the paper carriage the position of the latter. The ribbon B
after passing through the previously-mentioned slots A 2 A 3 is carried round a wire
yoke or equivalent D, fixed preferably near the bend in the plate and then passes
down, one end to each of two independent spools or reels E E¹ pivoted upon the
plate A so that their pivots E 2 lie parallel to the top portion A' of the plate.
Pivoted upon the plate A on the pin A. 7 near the bend is a two-armed spring F F
so arranged that one arm F presses upon the roll of ribbon upon the reel E, and
the other arm F1 presses on the ribbon on the reel E by which arrangement the
spring automatically adjusts itself upon its pivot A 7 to suit the varying diameters
of the rolls of ribbon when the ribbon is rolled off one reel and on to the other in
the working of the machine, the pressure being the same in all cases. The plate A
is provided with a pin A 8 or equivalent fitting into a hole in a suitable standard or
projecting portion G of the framework in which it is gripped by a set screw G¹ or
the like, a flat lateral extension A 9 (Fig. 4) formed on the pin A 8
with a
corresponding groove G 2 in the part G and ensures the plate A taking its proper
position in the machine. This positioning may however be effected by other means
such for example as a second pin similar to the pin A 8, or pins passed through the
plate into the support. Or the pin A 8 may be cylindrical and have a flat made
thereon for the set-screw G¹ to bear against, so that when the set-screw is tightened
up it not only grips the pin A 8 but so adjusts the flattened portion of the same that
the plate A resumes the desired position.
engages

page_text: The bracket A although of angle form in the present example, may be of other
shape as may be desired.
Each of the ribbon spools or reels E E' is provided with a ring of teeth H or
toothed disc wheel or equivalent placed upon opposite sides of the reels so that the
rings are in different and parallel planes or are otherwise not immediately opposite
each other; these engage with the teeth of a pinion I carried upon a spindle I'
rotated as the carriage of the machine travels, the whole spindle being arranged so
that it can be shifted longitudinally in its bearings in the frame of the machine,
carrying the pinion I with it so that the latter may engage alternately with either
of the toothed ribbon spools the spools being arranged out of line with each other
as aforesaid with the object that the pinion shall not engage both of them at once.
Or the pinion may for a like purpose be made axially adjustable on a fixed spindle.
The spindle I in the present instance, being longitudinally adjustable is provided
with peripheral grooves 12 with which engage a projection J upon a suitable plate
spring J or equivalent which thus serves the double purpose of securing the
spindle, and consequently the pinion, in its proper position in engagement with
either one of the ribbon spools and also provides the necessary friction to prevent
the spindle from slipping excepting when moved in the course of the operation of
the machine.
A convenient means of rotating the spindle I' and pinion I is to have a ratchet
wheel 13 at one end of the spindle engaging with a suitable spring pawl K upon the
spring barrel L which drives the paper carriage so that as this spring barrel
rotates in the direction indicated by the arrow in Fig. 3, the pawl K carries the
ratchet wheel 12 round with it while the spindle I can be turned in the same
direction at any time by hand if required for winding up the ribbon or for other
purposes. Or I may place the pawl K in operative connection with the paper
carriage or keys if desired, for a like purpose. The spindle I¹ preferably projects
at the front of the machine and it carries a milled head I by which it may be pulled
and turned.
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 type-writer a bracket such as A which carries the ink-ribbon spools and
ribbon-extension device such as A¹ whereby spools ribbon and device A¹ can all be
removed together without disarranging the ribbon or having to rethread it
afterwards.
2. In a type-writer a bracket such as A. carrying the ink-ribbon spools E E' and
having one end A 6 serving as a pointer substantially as and for the purpose herein-
before described.
3. In a type-writer a bracket such as A carrying the ink-ribbon spools E E' and
having slots as at A2 A3 and a guide D substantially as and for the purpose
hereinbefore described.
4. In a type-writer the combination with a bracket such as A and spools E'
pivoted upon it of a pivoted spring having two arms F F' substantially as and for
the purpose described.
5. In a type-writer the combination with two ribbon spools of a pivoted spring
having two arms such as F F' substantially as and for the purpose described.
6. In a type-writer the combination with the ribbon-spools E E' of toothed
wheels such as H having parallel and non-coincident axes and a pinion I axially
adjustable into and out of gear with either wheel substantially as and for the
purpose described and illustrated in the accompanying drawings.
7. In a type-writer the combination with the pinion 1 of a ratchet-wheel 1³
operatively connected therewith and a pawl K constituting an operative connection
between the barrel L or paper-carriage and the pinion I substantially as and for
the purpose described and illustrated in the accompanying drawings.

page_text: 8. In a type-writer the combination and arrangement of parts constituting a
complete apparatus for carrying and operating the ink-ribbon substantially as and
for the purpose described and illustrated in the accompanying drawings.
Dated this 9th day of September 1895.
