Improvements in Type-writers.
I, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent Agents,
45 Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
One feature of my improvement consists in the combination in a type writer, of
type wheels or segments and a number of key levers which serve to impart move-
ment thereto, which diverge forwardly and which have their front ends arranged in
parallel rows. Preferably the key levers will be arranged in two groups converging
rearwardly towards two points.
Another feature of my improvement consists in the combination with oscillating type
wheels or segments and a stop lever therefor, of a number of stop pins arranged
adjacent to the type wheels or segments and a number of forwardly diverging key
levers having their front ends arranged in parallel rows. Preferably these stop
pins will be arranged in a single row and in the form of an arc of a circle which is
concentric with the axis of the type wheels or segments. The key levers may with
advantage be supported by fulcra arranged in different rows corresponding to the
different rows in which their forward ends are arranged.
Another feature of my improvement consists in a particular method of supporting
a bar which is to be manipulated for effecting the spacing between letters and words.
A lever made in the form of a frame is fulcrummed at the rear end by pivots. At
the front of this frame-like lever there is a cross bar which extends above the rear
portions of the key levers hence every time one of the key-levers is manipulated the
said lever will be rocked upwards. When so moved upwards it effects the release
of the carriage and the carriage moves the distance required to properly present the
paper to receive another letter or symbol. A. lever fulcrumed to one of the knife-
edges-extends-rearwardly beneath the bar of the frame like lever. This lever may
be depressed at the forward end to effect the release of the carriage for spacing
between words or sentences. Attached to the forward end of the lever is a bar
extending parallel with the front of the front row of finger pieces and for as long
a distance as may be desired. The rear end of this lever also extends under one
arm of a lever which serves to prevent the hammer from operating at such times as
the movement of the carriage is effected merely for spacing between words or
sentences. This lever is of ordinary construction. The bar is supported not only
by the lever but also by two arms which are pivoted by pins to the base frame of
the machine and are fastened by screws or otherwise to the underside of the said
bar. A wire may be fastened to the underside of the bar to extend downwards and
laterally in the form of a hook beneath the forward extremity of the lever so as to
preserve the proper relations between the latter and said bar.
Another feature of my improvement consists in the combination with type-wheels
or segments having different kinds of letters arranged one above the other, of a
lever operating to elevate said type wheels or segments and having two forwardly
extending arms, one of which is rigidly connected to that arm of the lever which
extends to the type wheels or segments and the other of which is pivotally
connected to the said arm which extends to the type wheels or segments and is
constructed to operate upon the rigid forwardly extending arm. Under the two
forwardly extending arms I arrange stops and these I preferably make adjustable.
These stops will always project at different heights and limit the depression of the
two forwardly extending arms of the said lever. The rigid forwardly extending arm

page_text: can be depressed more than the one which is pivotally connected in place, hence by
operating either of these forwardly extending arms the type wheels or segments may
be elevated to present different rows of letters.
Another feature of the improvement consists in a combination of spools sup
porting an inking ribbon and supports for said spools whereby provision is afforded
for reversing the spools end for end to present a different portion of the ribbon
for usc.
The inking ribbon is made of more than sufficient width to ink any letter or
symbol upon either type wheel or segment and supported by two spools upon which
it is wound at the ends and upon either of which it is wound up to draw it along in
order to present fresh portions to the type wheels or segments. The spools are
arranged upon shafts having a slow rotary motion during the operation of the
machine and rest upon collars affixed to these shafts. The spools may be clamped
upon the shafts by expanding within them any suitable clamping devices attached
to the shafts. The spools have on one side bosses of very slight projection, and at
the other side bosses of considerably greater projection, hence they may be turned
upside down to present the ribbon in different planes to the type wheels or segments
and thus offer fresh surfaces for use.
The type-wheels or segments to which I have referred will preferably be made
readily detachable so that others containing different kinds of letters may be
substituted for them, and to enable a complete change to be made in a type writer,
I construct the finger pieces so that they may be readily detached from the key
levers to render it possible to substitute other finger pieces marked with different
kinds of letters. Preferably the finger pieces will be fastened to the key levers by
spring-catches.
Another feature of my improvement consists in the combination of a type bearer
of any suitable kind, a finger piece for operating the same, and a spring or elastic
connection intermediate of the two parts whereby a dwell of the type in printing
will be secured. By this construction I conduce to a more perfect printing.
prefer to use oscillating type wheels or segments and to employ vertical drivers for
imparting oscillating movement to them through pairs of fingers having an elastic
connection with the drivers and acting on pins extending from the type wheels or
segments.

Improvements in Type-writers.
1, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co., Patent
Agents, to Southampton Buildings in the County of Middlesex, 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 -
One feature of my improvement consists in the combination in a type-writer, of
type wheels or segments and a number of key levers which serve to impart move-
ment thereto, which diverge forwardly and which have their front ends arranged in
parallel rows. Preferably the key levers will be arranged in two groups converging
rearwardly towards two points.
Another feature of my improvement consists in the combination with oscillating
type wheels or segments and a stop lever therefor, of a number of stop pins
arranged adjacent to the type wheels or segments and a number of forwardly
diverging key levers having their front ends arranged in parallel rows. Preferably
these stop pins will be arranged in a single row and in the form of an arc of a circle

page_text: which is concentric with the axis of the type wheels or segments. The key levers
may with advantage be supported by fulcra arranged in different rows corresponding
to the different rows in which the forward ends are arranged.
Another feature of my improvement consists in the particular method of sup-
porting a bar which is to be manipulated for effecting the spacing between letters
and words.
Another feature of my improvement consists in the combination with type wheels
or segments having different kinds of letters arranged one above the other, of a
lever operating to elevate said type wheels or segments and having two forwardly
extending arms, one of which is rigidly connected to that arm of the lever which
extends to the type wheels or segments and the other of which is pivotally connected
to the guard arm which extends to the type wheels or segments and is constructed
to operate upon the rigid forwardly extending arm. Under the two forwardly
extending arms 1 arrange stops and these I preferably make adjustable. These
stops will always project at different heights and limit the depression of the two
forwardly extending arms of the said lever. The rigid forwardly extending arm
can be depressed more than the one which is pivotally connected in place, hence
by operating either of these forwardly extending arms the type wheels or segments
may be elevated to present different rows of letters.
Another feature of the improvement consists in a combination of spools supporting
an inking ribbon and supports for said spools whereby provision is afforded for
reversing the spools end for end to present a different portion of the ribbon for use.
The type wheels or segments to which I have referred will preferably be made
readily detachable so that others containing different kinds of letters may be
substituted for them, and to enable a complete change to be made in a type-writer
I construct the finger pieces so that they may be readily detached from the key
levers to render it possible to substitute other finger pieces marked with different
kinds of letters. Preferably the finger pieces will be fastened to the key levers' by
spring catches.
Another feature of my improvement consists in the combination of a type bearer
of any suitable kind, a finger piece for operating the same, and a spring or elastic
connection intermediate of the two parts whereby a dwell of the type in printing
will be secured. By this construction I conduce to a more perfect printing.
prefer to use oscillating type wheels or segments and to employ vertical drivers for
imparting oscillating-movement to them through pairs of fingers having an elastic
connection with the drivers and acting on pins extending from the type wheels or
segments.

Figure 22 is a top view of one of the type wheel drivers used in this modified
construction of machine.
Similar letters of reference designate corresponding parts in all the figures.
A A² designate two type wheel segments arranged within a cylinder B having
an opening rearwards of which are arranged an inking ribbon, R, a shield S, for the
ribbon provided with a hole opposite the axis of the type wheel segments and a
holder for paper upon which writing is to be done. Rearwards of the hole in the
ribbon shield a hammer C is arranged. The type wheel segments are provided
with different letters of the alphabet and other symbols which are to be printed.
They leave several rows of the letters and symbols arranged one above another.
Provision for a vertical movement of the type wheel segments is afforded to enable
any row of letters or symbols to be presented in a horizontal plane, which will
enable them to be one at a time presented in a position opposite the hole in the
ribbon shield and the hammer. The type wheel segments are adjustable rotarily to
present the letters and symbols of any given row, one at a time, in a position opposite
the hammer. The haminer forces the paper upon which the writing is to be done
against the inking ribbon and the latter against a letter or symbol presented opposite
the hole in the ribbon shield. The paper is secured in a carriage W, which is
moved in a direction parallel with the front of the machine and moved longitudinally
by means of rollers which are journalled in the carriage.
The inking ribbon R is made of more than sufficient width to ink any letter or
symbol upon either type wheel or segment, and supported by two spools R¹ upon
which it is wound at the ends and upon either of which it is wound up to draw it
along in order to present fresh portions to the type wheels or segments. The
spools R are arranged upon shafts R having a slow rotary motion during the
operation of the machine, and rests upon collars, affixed to these shafts. The spools
may be clamped upon the shafts by expanding within them any suitable clamping
devices, attached to the shafts. The spools have on one side bosses of very
slight projection and at the other side bosses of considerably greater projection,
hence they may be turned upside down to present the ribbon in different planes to
the type wheels or segments and thus offer fresh surfaces for use.

page_text: D designates a number of key levers or finger keys, fulcrumed between their ends
upon a bar d.
At the rear ends they extend through slots in a bar d¹ and at the
forward ends through slots in a bar do. The bars d' d may be made integral with
the base frame of the machine, but the bar d may be more advantageously made
separate and secured thereto. A bar 10 extends across the top of the bar d
thereby securing the key-levers D in place. The front ends of the key levers D
extend to different points and are provided with upright fingers D¹ having at their
terminals finger pieces D³.
E designated levers which are operated by the key levers D and serve to impart
rotary motion to the type wheels or segments. They consist, as here shown, of a
rock shaft el, arms e² extending forwardly therefrom, arms e³ extending horizontally
toward each other across the rear end portions of the key levers D and upright
arms which are provided at the upper extremities with vertical drivers G having
fingers which engage with pins on the hubs of the type wheels or segments
to impart rotary motion to the latter. The pin 2 of each type wheel extends down
between the fingers g¹ y² of the corresponding driver and the pin ¹ of each type
wheel will, when the parts occupy their normal positions be in advance of the
finger of the corresponding vertical driver. The arms of each of the levers E
extend over but one-half of the key-levers and the upright arm of each lever E
operates solely upon one of the type wheels or segments.
The rock shaft e¹, the arms e² and the arms e of each lever E are shown as being
made integral, but the arm e³ of each lever is detachably connected with the arm e
thereof. As here shown, each arm is longitudinally slotted and is secured to the
arm 2 by means of a screw whose body passes through the slot and engages with
a hole in the arm e². This connection affords provision for adjusting the arms e³
into the best possible positions to co-act with the key levers.
The key levers not only serve to impart movement to the type wheels but also to
operate devices whereby the positions in which the type wheels shall come to rest
will be determined. For the latter purpose, their rear end portions are extended
under a number of vertical stop pius 1, and will raise the latter when the forward
extremities of said key levers are depressed. These stop pins are arranged in an are
of a circle concentric with the axis of the type wheels or segments and they slide
through two sector shaped frames I¹ 12, which are beneath a base flange 6 with
which the cylinder B is provided. Between the frame and collars or shoulders.i
with which the stop-pins-l-are-provided, springs are coiled around the stop pins.
These springs serve to depress the stop pins so that they will bear upon the rear
portions of the key levers. Whenever a key lever is depressed by manipulating its
finger pieces it will not merely oscillate one of the type wheel segments through one
of the levers E but will also raise one of the stop pins I for the purpose of arresting
such type wheel segment through the agency of a stop lever J. This stop lever .J
is fulcrumed between its ends coincidently with the axis of the type wheels or
segments. Its forward arm projects over the frame I so that when moved it can
be arrested by any one of the stop pins I which may be raised and its rear end
obtrudes in the way of those ends of the type wheel segments which are advanced
to bring any letter or symbol arranged thereon opposite to the hammer C.
The key levers converge rearwardly towards two points because of the close
proximity in which the stop pins are located.
They are thus separated at the front ends. Some of the levers are bent to
one side at the forward ends to secure the best possible arrangement of the finger
pieces.
Because the front ends of the key levers terminate in three rows, there is formed
a key board comprising three rows of finger pieces. As the fingers D supporting
these three rows of finger pieces are of different lengths, the three rows of finger
pieces are of different heights. To equalize the leverage as far as practicable the
bar dis curved longitudinally and has fulcra in three different vertical planes. The
fulcra d² d³ d are of inverted V form and the key levers are notched on the under
side to fit upon such fulcra. At the top of each vertical driver shown in Figures!

page_text: to 18 inclusive, is a bracket ³ which may be formed integral therewith or attached
thereto. It has two arms 1 and 2, in which an upright shaft y' is journalled. On
the top of the shaft is affixed a plate y and the fingers y g² are formed integral with
this plate. A lag or pin, 3, extending downwardly from this plate into an arc
shaped groove formed in the upper arm, 1, of the bracket ³ concentrically with the
axis of the shaft g', limits the motion of the plate g. A spring coiled around the
shaft, fastened at one end thereto by a screw to a collar g' on the shaft and
impinging at the other end against the bracket, oscillates the shaft so as to throw
the fingers forward, but allows the fingers to yield backwards. The collar g' serves
to prevent the shaft from moving upwards ont of the bracket and a shoulder which
is formed above the upper arm of the bracket g³ prevents the downward movement
of the shaft.
When either of the vertical drivers is moved forward it propels the corresponding
type wheel segment and has such a range of movement that after the movement of
the segment shall have been arrested by the stop lever, the vertical driver may
move sufficiently far forward to cause an oscillation of the plate g on the axis of the
shaft 9. This oscillation will occur because when the segment is arrested the
pin or which happens to be in engagement with one of the fingers g' or g²
belonging to the said vertical driver will be precluded from further movement.
When the movement of the vertical driver is reversed owing to the release of the
key lever whereby it was operated, the vertical driver will fail, during its initial
rearward movement, to impart any movement to the segment because it will have
no effect upon the type wheel until after it shall have moved sufficiently far
rearwards to allow the plate o to oscillate into its normal position. After this, the
continued rearward movement of the vertical driver will cause the finger g' of such
driver to act upon the pin 2 of the type wheel and pull it back. An appreciable
time will be consumed in effecting the oscillating movement of the plate g by the
extra movement of the vertical driver, and on the return or backward movement of
the driver up to that point when the plate g has completely resumed its normal
position. Thus a dwell in the movement of the type wheel after the presentation
of a letter or symbol is secured. An incline 4 on the finger 2 is advantageous in
securing the most effective operation of the type wheel under impulses from said
finger 2.
In the modified construction illustrated in Figures 19 to 22 inclusive, the plates g
are not supported by the vertical drivers G but by pillais go which are erected
upon the cross bar so as to oscillate upon the same. The forward movement of
the plates, or, in other words, that movement which is toward the ends of the key
levers that are manipulated by the operator, is limited by stops g. The plates g
are made in the form of levers and their arms which extend beyond the supporting
pillars contact with stops inserted in a frame B¹ through which the stop pins I
move vertically. The stops g" are made in the form of screws and have flattened
portions so that by rotating them they may be made to vary their limiting effect
upon the movement of the plates and consequently of the fingers q¹g². The
fingers have inclines 4, which operate upon the pin / of the type wheel segments.
The plates, are slotted intermediately of the supporting pillars g³ 910 and the
fingers gg The drivers have at their upper extremities upwardly extending
pin-like projections which enter slots g". At the under side of the plates g
springs consisting of strips of steel are at one end attached. These extend across
the rear of the vertical drivers G and normally hold the pin-like projections of the
latter against the forward side of the slots 12 in the plates g. The slots g¹² are
much larger than the said pin-like projections of the vertical driver. Consequently
after the vertical drivers shall have moved the plates as far rearward, or, in other
words, toward the hammer C, as is possible, the vertical drivers are capable of
moving still further forward as the springs g³ will then yield to allow of this. This
extra movement of the vertical drivers and the corresponding returning movement
which the vertical drivers will have before imparting any forward movement to the
plates produces a dwell.

page_text: When the plates y in either example of my improvement come to rest their
fingers are at the sides of the pins 2 of the type wheel segments (sec Figures 18
to 22), and these fingers will form stops to prevent the accidental movement of the
type wheel segments. The stops g" will make the fingers come to rest in the proper
position with reference to the pins 2 of the type wheel segments.
On the stop lever J is a projection here shown as made in the form of a block
fastened to the said lever by rivets and projecting between the pairs of fingers g' g²
and hence the latter will return the said lever to its normal position if it should not
be returned by the springs. Whichever pair of fingers g g happens to be at
rest will form a stop whereby the return movement of the said lever will be limited.
The two pairs of fingers acting in conjunction with the block serve as a lock to
hold the stop lever in its normal position.
The springs are fastened to fixed supports on a cross bar ja and at the free
ends impinge against the ends of a segmental flange with which the tubular shaft
supporting the stop lever is provided. It is possible in some forms of my invention
to dispense with one of the fingers of each pair.
While I deem it best to locate the elastic connection between fingers such as I
have described and vertical drivers, it is possible to locate the spring connection
elsewhere between the finger end of a key and a type-bearer.
This carriage is moved in the direction of its length by a spring in a well known
manner. The means for controlling its movement are so well known that I have
not illustrated them. L designates a lever made in the form of a frame and
fulcrumed at the rear end by pivots l. At the front of this frame-like lever there
is a cross bar which extends above the rear portions of the key levers D, hence
every time one of the key levers is manipulated the lever I will be rocked upwards.
When so moved upwards the lever L effects the release of the carriage and the
carriage moves the distance required to properly present the paper to receive
another letter or symbol. A lever D fulcrumed to one of the knife edges d extends
rearwardly beneath the bar of the lever L. This lever may be depressed at the
forward end to effect the release of the carriage for spacing between words or
sentences. Attached to the forward end of the lever D' is a bar d' extending
parallel with the front of the front row of finger pieces and for as long
a distance as may be desired. The rear end of this lever D5 also extends under
one arm of a lever M which serves to prevent the hammer from operating at such-
times as the movement of the carriage is effected merely for spacing between words
or sentences. This lever M is of ordinary construction, hence I do not regard it as
necessary to illustrate all the parts which co-act therewith to preclude the operation
of the hammer, during movements of the carriage made for spacing between words
and sentences. The bar d' is supported not only by the lever D" but also by two
arms D, which are pivoted by pins de to the base frame F of the machine and are
fastened by screws or otherwise to the under side of the said bar.
A wire d may
be fastened to the under side of the bar d to extend downwards and laterally in the
form of a hook beneath the forward extremity of the lever De so as to preserve the
proper relations between the latter and said bar.
The hubs of the type wheels or segments fit upon and are supported by an
upright shaft Q. Under this extends a bent lever T consisting of an arm t
extending width-wise of the machine and fulcrumed by a screw to an upward
extension upon the base frame of the machine. From the arm an arm t³
extends rearwardly beneath the lower extremity of the shaft Q. To the arm t
of the lever T an arm is rigidly attached. This arm extends forwardly, and
has at its front extremity an upwardly extending finger and a finger piece attached
thereto. The finger and finger piece may be like the fingers and finger pieces of
the key levers. On the finger piece T of the arm I mark "Fig.", to indicate
that by depressing this arm the type wheels or segments will be elevated to a
position which will bring the figure marked thereon in the same plane as the
hammer C. A detent is pivotally connected at its lower end by a screw t
with the forward portion of the arm and has near the upper end a hook

page_text: which may engage with a hole in the bar 10. It will be readily understood that
the arm t may be depressed and retained in this depressed position to enable the
figures on the type wheels or segments to be used by merely swinging the detent d³
forward to engage with the bar after the arm shall have been properly
depressed. A stop t' consisting of a screw fitted in a tapped hole in a portion of
the frame F and projecting upwardly under the arm may limit the downward
movement of the arm (. Such stop may, of course, be adjusted as may be
desirable.
The shaft Q is lowered by a spring in a well known manner when released.
The arm of the lever T has also affixed to it an armi ts which at the forward end
is provided with a finger and finger piece similar to the corresponding parts of the
key levers. This arm to is not, however, rigidly connected to the arm of the
lever T, but is pivotally connected thereto by the screw upon which the lever T
is fulcrumed. This arm is provided with a laterally extending lug which
projects over the arm of the lever T, hence if the arm to be depressed, it will
effect the depression of the arm and consequently cause an oscillation of the
lever and a raising of the type wheels or segments. There is a stop t¹º for
limiting the depression of the arm 18 of the lever T and this stop will preferably
be made and fitted in place like the stop t. The stops t 10 are so arranged that
the arm of the lever T cannot be depressed so far as the arm of said lever.
When the arm t³ is depressed it will elevate the type wheels or segments so as to
bring another row of letters or symbols opposite the hammer C. In the present
instance, it is intended that capital letters shall be brought into operation by the
depression of the arm 8 on the lever T, hence the finger piece of this arm is marked
with the letters "Cap." A detent is pivoted at the lower extremity to the
arm and provided near the upper end with a hook, which, when said arm is
depressed, may engage with a hole in the bar de so as to hold the said arm depressed
and consequently maintain the type wheels or segments in position for the continued
use of capital letters.
The type wheel segments are removable from the shaft Q, whereby they are
supported, and therefore, others having different styles of letters may be substituted
for them. To provide for substituting different letters and symbols upon the key
levers D so that the letters and symbols upon the key levers may be made to
correspond with those upon the type wheel segments, the fingers D² are detachably
connected with the key levers. A convenient means of doing this consists in
forming the fingers of pieces of sheet metal riveted or otherwise secured to the
key levers and extended upwardly to form pairs of resilient strips having the upper
extremities turned laterally and provided with notches 3, and to form the fingers
in the shape of buttons having pins extending from the under side and so
disposed as to be able to engage with the notches, in the laterally turned extremities
of the pairs of strips forming the fingers. The pins are bent laterally to a slight
extent so as to be the more readily slipped into the notches.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, as communicated to me by my
foreign correspondent I declare that what I claim is :
