I, JOSEPH MARCH WEBSTER of 22 Waverley Road, Sefton Park, Liverpool
in the County of Lancaster, Gentleman do hereby declare the nature of this
invention to be as follows:-
This invention has reference to the construction and arrangement of typewriting.
machines the object being to provide a simple form of machine having only a few
keys, for which purpose the keys are so arranged that either of three distinct,
characters can be printed by operating any one key. Each type block is formed
with three types and is secured to the end of a flexible or spring bar that is,
connected to a type lever so as to allow the type to have a sideways as well as a
radial movement. As the type block advances towards the paper to be printed on
it slides into and is guided by a centering device of tapering form provided with
antifriction rollers over which the inking ribbon passes, as it is automatically
wound in alternate directions from one to the other of two spools placed beneath
the type keys.
'The centering device is placed above the paper cylinder or platen which is
carried in a compound slide capable of two movements at right angles with each
other.
The type levers and keys are placed in such a position with relation to the
cylinder or platen that the writing may be seen without moving said cylinder or
platen.
The base plate of the machine is provided with a suitable guide way upon which
a guide is mounted so as to be capable of sliding thereon; in this guide the paper
cylinder or platen, which is carried in a suitable frame, is adapted to travel in a
direction at right angles to the movement of the above mentioned guide. The
guide is connected by a link or links to one or more levers actuated by a key or
keys to move and if desired hold the cylinder or platen in such a position as to
enable the paper to be printed by any one of the three types. When the key or
keys is or are released the slide is brought over to its normal position by a spring
or equivalent device.
The cylinder platen frame is caused to travel from right to left. for spacing &c.
by means of a pawl which engages in a rack bar fixed thereto. The pawl, which
may be self-locking, is actuated by levers which may be bell crank levers and a
rod or long crank pin that extends across the edges of the type levers of the set
arranged on one side of the paper cylinder or platen so that when any one of these
type levers is depressed the crank pin is also depressed and the pawl moved. In
order that the pawl may also be operated when a type lever of the set arranged on
the other side of the paper cylinder or platen is operated the lever arms extend over
the paper cylinder or platen and are connected by a link to similar levers on the
opposite side of the cylinder or platen thus if any type lever of either of the two'
sets of type levers be depressed, the pawl will be moved.
To one of these levers a spacing key rod is connected; also one end of a
connecting rod, the other end of which is pivoted to a radiating arm carrying a
pawl that rotates the before mentioned inking ribbon spools alternately. When
the spool with which this pawl engages is full the pawl is automatically disengaged
therefrom and put into gear with the other or empty spool, thus causing the ribbon
to travel in the opposite direction. The two spools may be placed on one side
of the machine and the ribbon guided over rollers and beneath the type so as to

page_text: leave the left hand side of the machine open and thus enable the writing to be
inspected.
The type levers are placed side by side in two sets and radiate on pivots located
at such a distance from and on each side of the paper cylinder or platen that any
one of the three types shall strike direct thereon according to the position in which
the paper cylinder or platen frame is placed. The centres of the pivots may be
somewhat below the centre line or striking surface of said cylinder or platen to
allow of clearance between one type block when in its normal position (i.e. away
from the cylinder or platen) and the one opposite to it when in its printing
position, (i.e. touching the cylinder or platen).
The type levers and key levers are connected by wire tension rods and are
brought back into their normal positions by suitable springs sufficiently strong to
withdraw the type block from between the before mentioned antifriction rollers in
the centering device which may also be provided with side springs for guiding the
type in the line space. Rubber or other stops are provided for preventing the
springs bringing the type levers too far back.
It will thus be understood that each set of type levers and spring bars are set
directly opposite one another on each side of the cylinder or platen and over the
centering device which they enter radially on being depressed. The two sets of
spring steel bars carrying the type blocks when free stand at an angle with each
other, i.e. their lower ends are closer together than their upper ones there being
sufficient space left at their lower ends to allow one of either set to be depressed
for printing without coming in contact with the corresponding one of the opposite
set. The object of the spring bars is to allow the outer ones of each set (that is
those farthest away from the middle of the centering device) to spring and force
the other types sufficiently sideways to enable them to strike one common centre
between the before mentioned antifriction rollers. The type may be set on the
outermost bars so as to allow for the curving sideways of the spring bars which
preferably are about vertical on the edges when printing.

Improvements in Typewriting Machines.
I, JOSEPH MARCH WEBSTER, of 22, Waverley Road, Sefton Park, Liverpool,
in the County of Lancaster, Gentleman, 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 has reference to the construction and arrangement of typewriting
machines, the object being to provide a simple form of machine having only a com-
paratively few keys, for which purpose the keys are so arranged that either of three
distinct characters can be printed by operating any one key. Each type block is
formed with three types and is secured to the end of a flexible or spring bar that is
connected to a type lever so as to allow the type to have a sideways as well as a
radial movement. As the type block advances towards the paper to be printed on,
it slides into and is guided by a centering device of tapering form provided with
antifriction rollers or guides over which the inking ribbon, when used, passes, as it
is automatically wound in alternate directions from one to the other of two spools
placed beneath the type keys.
The centering device is placed above the paper cylinder or platen which is
carried in a compound slide capable of two movements at right angles to each
other.
The type levers and keys are placed in such a position with relation to the

page_text: cylinder or platen that the writing may be seen without moving the said cylinder
or platen.
The base plate of the machine is provided with a suitable guide way in or upon
which works a slide, in which the paper cylinder or platen, which is carried in a
suitable frame, is adapted to travel in a direction at right angles to the movement
of the said slide. The slide is connected by links to levers actuated by a key or
keys to move and if desired hold the cylinder or platen in such a position as to
enable the paper to be printed by any one of the three types. When the key or
keys is or are released, the slide is brought over to its normal position by a spring
or equivalent device.
The cylinder or platen frame is caused to travel from right to left for spacing &c.,
by means of a pawl which engages in a rack bar fixed thereto. The pawl, which
may be self-locking, is actuated by levers, which may be bell crank levers, and by
a rod or long crank pin that extends across the edges of the type levers of the set
arranged on one side of the paper cylinder or platen so that when any one of these
type levers is depressed, the crank pin is also depressed and the pawl moved.
In
order that the pawl may also be operated when a type lever of the set arranged on
the other side of the paper cylinder or platen is operated, the lever arms extend
over the paper cylinder or platen and are connected by a link to similar levers on
the opposite side of the cylinder or platen; thus if any type lever of either of the
two sets of type levers be depressed, the pawl will be moved.
To one of the levers a spacing key rod is connected; also one end of a connecting
rod, the other end of which is pivoted to a radiating arm carrying a pawl which
rotates the before mentioned inking ribbon spools alternately. When the spool
with which this pawl for the time being engages is full, the pawl is automatically
disengaged therefrom and put into gear with the other or empty spool, thus causing
the ribbon to travel in the opposite direction. The two spools may be placed on
one side of the machine and the ribbon guided over rollers and beneath the type so
as to leave the left hand side of the machine open and thus enable the writing to he
inspected.
The type levers are placed side by side in two sets and radiate on pivots located
at such a distance from and on each side of the paper cylinder or platen that any
one of the three types will strike direct thereon, according to the position in which
the paper cylinder or platen frame is placed. The centres of the pivots may be
somewhat below the centre line or striking surface of said cylinder or platen to
allow of clearance between one type block when in its normal position (i.e. away
from the cylinder or platen) and the one opposite to it when in its printing position,
(.e. touching the cylinder or platen).
The type levers and key levers are connected by wire tension rods and are
brought back into their normal positions by suitable springs sufficiently strong to
withdraw the type block from between the before mentioned antifriction rollers in
the centering device, which may also be provided with side springs for guiding the
type in the line space. Rubber or other stops are provided for preventing the
springs bringing the type levers too far back.
The
It will thus be understood that each set of type levers and spring bars are set
directly opposite one another on each side of the cylinder or platen and over the
centering device which the spring bars enter on being depressed. The two sets of
spring bars carrying the type blocks, when frce, stand at an angle with each other,
.e. their lower ends are closer together than their upper ones, there being sufficient
space left at their lower ends to allow one of either set to be depressed for printing
without coming in contact with the corresponding one of the opposite set.
object of the spring bars is to allow the outer ones of each set (that is those
farthest away from the middle of the centering device) to spring and force the
other types of the set sufficiently sideways to enable them to strike one common
centre between the before mentioned antifriction rollers. The type may be set
on the outermost bars so as to allow for the curving sideways of the spring bars,
which preferably are about vertical on the edges when printing.

are connected
The base plate 1. is provided with guide ways 4. 5. in which works two
short slides 6. 6. one on each side of the base plate, which
together by a compound slide 7. carrying a frame 8. in which the paper cylinder 9.
(hereinafter called a platen) is mounted to slide in a direction at right angles to
the lower slides 6. The slide 7 is connected by links 10. to two levers 11. & 12.
arranged outside the side frames 2. 3. and fixed on a rock shaft 13 and actuated
from the extended arm of the lever 11. by a rod 14. which connects it to one arm
of the bell crank lever 15. which is moved by one or other of two keys 16 & 17.
The key 16. when depressed to its full limit, moves the platen 9. into its middle
position, indicated by the central dotted circle 18 of Fig. 4.
The other key 17. is pivotted to the same lever 15. but nearer to the fulcrum 19.
thereof so that upon depressing this key to the same depth as the key 16, the
platen 9. will be moved to the full limit of its traverse, that is to say until the
centre line of the platen is directly beneath the outermost type of the set of three
type as shewn in full lines in Fig. 4. To enable the lever 13. to be thus operated
by the key 17 independently of the key 16, the lower end of the rod connecting this
key 17 with the lever 15, is slotted out as shewn, so as to allow of the free
movement of the connecting pin 20 carried by such lever. The rods connecting the
keys 16 & 17. are provided with stops or locking pieces 21. 22. and have a small
amount of sideways movement in the guide plate 23. so that when either of the
keys 16 or 17 is depressed and moved slightly sideways, the stop pieces 21. 22. will
be caused to engage with a projection 24 from the side frame 2. and thus hold the
platen 9. in the position into which it has been moved by depressing one of the
keys, so as to enable one class of letters or numerals to be printed until the said key
is released. 25 are coiled springs for drawing the slides 6 inward and so move the
platen 9 into the position shewn in Fig. 1, when the keys 16. and 17. are released,
so as to then print only from one of three classes of type or numerals. 26. 26. are
the type levers arranged in two sets, those in each set being placed side by side and
mounted to turn upon a pin 27. secured to and between the side frames 2. and 3.
and the axis of which is located at a lower level than and at such a distance from

page_text: that of the platen roller 9. that one or other of the three characters V. W. X.
Fig. 10. on a type block 28. will strike direct on the platen 9. according to the
position in which the latter is placed. Each type block 28. is con.icetel to the
Corresponding type lever 26, by a pair of flat spring plates 29. the arrangement
being such that when either of the pairs of spring plates of one set is depressed as
shewn in Figs. 4. and 11, it will not foul the pairs of spring plates of the other ser.
Each type lever 26. is of bell crank form, its longer arm being provided with a
lateral guide or strip 30, for guiding it into position. The upper end of the long
arm of each lever is bent to the form shewn in Figs. 1. and 4, and to its opposite
sides are secured a pair of the spring plates 29, which are composed of thin flexible
steel strips which project downwards from the lever arm, at such an angle that when
the said lever arm is depressed, for printing, they will assume a vertical or
approximately vertical position (Fig. 4.) Each type block 28 18 secured between
and to the lower ends of the spring plates 29, conveniently by soldering, and is
provided at its lower side with three characters indicated at V. W. X, and also
with projecting eud portions Y. Z which slide between end pieces on the centering
guide 31, hereinafter described. To the shorter arms of the type levers 26 are
jointed the lower ends of tension wires 32, the upper ends of which are jointed to
key levers 33, which are pivotted on one or other of the pins 34 or 35, and are so
shaped and arranged as to clear each other and to permit of the several keys being
equally depressed.
The type levers 26 are each provided with a shoulder or projection 36. formed
on the shorter arm thereof and against which press the teeth of a comb spring 37
for the purpose of withdrawing the corresponding type block 28 from between the
sides of the guard 31 and returning the type lever to its normal position when the
corresponding type key is released.
38. is a cushion or stop piece of material such as leather or rubber arranged
between the side frames 2. and 3, and serving to prevent the levers 26. from being
carried too far back.
The shanks 39 of the type keys 40,, are made of different lengths to form a sloping
key board as shewn, and are arranged to slide through guide pieces 41. secured to
cross pieces 42. on the side frames 2. and 3. as shewn in Figs. 2 and 5.
The pairs of spring plates 29. are made sufficiently long and flexible to enable
each of them, whilst descending, to bend when necessary and to allow the type
block 28. carried thereby to be held perpendicular and linable whilst between the
contracted part of the centering guide 31. as shewn in Fig. 11. in which one of the
outside type blocks is shewn depressed, and the corresponding pair of spring plates
is represented as pressing the remainder of the pairs of spring plates, of the set,
together. Fig. 12. shews the normal position of the spring plates 29, and type
blocks 28.
The centering guide 31 consists of two curved sides secured to the side
frames 2. and 3. and provided if desired at their lower ends with antifriction rollers,
though I have found that these are unnecessary when the sides and ends are
correctly shaped and fitted as shewn. On the inner side faces of the centering
guide 31, curved grooves may advantageously be formed, arranged opposite the
types as shewn in Fig. 10, so as to prevent the sides of the types touching the said
guide or the projecting rits thereon and so becoming damaged or worn.
The inking arrangement can be modified according to circumstances. Thus when
the characters are large and bold, they can be inked by striking through an inking
ribbon 83, represented by the dotted line in Fig. 22. Each end of the said ribbon
is secured in the usual manner, to, in this case, an upper and lower spool 84 & 85.
These spools are carried in bearings secured to the side frame 3, and are each
Intermittently rotated alternately in different directions, by engaging one or.other
of the pawls 86, 87, with toothed ratchet wheels on the spool shafts 88, 89.
The
two levers 90, 91 are coupled together by a link 92 and the lower lever 91, is
connected with a lever 53 (hereinafter more particularly referred to) by another
rod 93 so that when this rod is depressed by the lever 53, either when spacing or

page_text: printing, the ribbon 83 will be partly wound on to the spool which is in gear.
When one spool, say the upper one, in Fig. 22, is full, the pawl 86 working it, is
thrown out of gear, and the other one ci. 87, is thrown into gear, whereupon the
ribbon 83 will be caused to travel in the opposite direction. The ribbon is placed
in a direct line and vertically over the platen, and is guided over small rollers 9+
near the lower end of the centering guide 31. The frame sides shown in Figs. 1
and 4 will, when an inking ribbon is employed, require to be slightly modified by
using two upright bars placed some distance apart instead of the one as shown.
When the types are small, they may advantageously be inked by a pad 43,
(Figs. 11, 12 and 14 to 20 inclusive) arranged and operated in the manner I will
now describe.
The pad 43 is carried by a small frame 44 pivoted on a pin 45 the ends of which
take into sliding rods 46 and 47 that are connected together at their other ends by
a bar 48.
One of the pins 46 is provided with a spring 49, one end of which presses against
the inner surface of the side frame 2, whilst the other end rests against a pin 50
fixed to the rod 46, and against the opposite side of which takes the free end of a
curved bell crank lever 51, Figs. 10. and 17. to 20. inclusive.
This lever 51. is actuated from its shorter arm by a connection 52. secured to a
spacing lever 53. (Figs. 17. 18. and 21.) carrying a stop piece 54. the arrangement
being such when the arm of the lever 53. carrying the connection 52. is depressed,
the lever 51 will be operated so as by acting on the pin 50, to move the pins 46
and 47. end ways against the action of the spring 49. and bring the inking pad 43
directly beneath the type block 28, (see Figs. 12. 17. and 19.) where it will be held
by the action of the stop piece 54 against a spring tongue 55 on the end of the
pin 46, as shewn in Fig. 17.
As each type block descends, the arm of the lever 53 (Fig. 21.) carrying the
extension 52, is automatically moved upwards and at the required time, that is
immediately after the type block has touched the inking pad 43, the stop piece 54.
is moved away from in front of the spring tongue 55, whereupon the compressed
spring 49, being now released, forces the pad out of the way of the still descending
type block as shewn in Figs. 11. 18. and 20.
1
When the lever 53 again descends into its normal. position, the stop piece 54. will
act upon and depress the tongue 55. (Fig. 18.) until the same has been moved
longitudinally to the right by the action of the lever 51. sufficiently to escape the
downwardly extending portion of the stop piece, when it will rise again into the
position shewn in Fig 17.
Thus each type block is inked by being pressed, during one portion of its descent,
on the pad which is then automatically and quickly removed from beneath the type
block to permit the same to come into contact with and making an impression on
the paper carried by the platen.
As the type returns to its normal position, the bell crank lever 51 will again
move the pad into position, ready for inking the next descending type block.
The inking pad 43. consists of a piece of absorbent material for example felt, on
which ink is placed, it may be by an inking roller 55* against which the pad 43
moves. The roller 55* is carried in bearings which allow of a small amount of
vertical movement, see Fig. 12. As the end of the pad is caught by a descending
type block 28, the opposite end, which is weighted, tilts a little as shewn by the
doited radius line 56. The portion of the pad on which the type block catches, is
preferably pivotted at right angles on the pin 57, shewn in the dotted lines of the
inverted plan Fig. 15, to allow it to adjust itself and take an even bearing across
the face of the type block, so that each of the three characters will be inked.
Figs. 14. and 15. shew the two alternate sides of the pad and Fig. 16. is a side view
of the same. Fig. 10. is an end view shewing the bell crank lever 51 and the
pin 50 against which this lever presses. 58 is a suitable support for carrying the
pivot pin 59 of the lever 51; it is secured to the side frames 2. and 3.
The paper roller or platen 9. is automatically and intermittently moved by its

page_text: frame from right to left, to form lines of printing, by means of a pawl 60 (Figs. 2.
4. 5. and 13.) having a wide lip or edge so as to engage with a rack bar 61 on the
platen frame & in either of the three positions into which the said frame may be
inoved for printing one or other of the three characters on cach type block.
The pawl 60 is actuated by a bell crank lever 62 which is pivotted to the side
frame 3. and has its longer arm connected by a halt twisted link 63. to one arm of
another lever 64. arranged at right angles to it. This lever 64. is fixed upon one
end of a hollow shaft 65. which carries a lever arm 66. at its opposite end. One
arm of the lever 64 is connected by a short link 67 (see Fig. 4.) to one end of the
lever 53 used for operating the inking mechanism. The other and shorter arm of
the lever 64. carries one end of a rod or long crank pin 68, which is arranged
parallel with the hollow shaft 65, and has its other end carried by the lever arm 66.
The other end of the lever 53. carries one end of another rod or long crank
pin 69, the other end of which is carried by a second lever arm 70. as shewn in
Fig. 6. The two rods or crank pins 68. 69. when in their normal positions, as
shewn in Fig. 1. are pressed against the inner edges of the type levers 26 by the
curved spring 71 (Figs. 4. and 6.), so that when either of the type levers 26 is
depressed, as shewn in Fig. 4, one or other of the crank pins 68 69. will be also
depressed thus operating the bell crank lever 62 so as to cause it to draw back the
pawl 60. and cause it to engage with the next tooth on the feed rack bar 61.,
(Fig. 13).
The position of the fulcra of the levers 53 and 64. and the length of the lever
arms, are so arranged that the extent of movement of the bell crank lever 62 will
be the same whichever rod or crank pin 68 or 69 is directly operated by the type
lever 26.
As the depressed type lever returns to its normal position, the bell crank lever 62
is moved in the opposite direction by the action of the spring 71, and carries the
pawl 60 forward, thus feeding the platen 9 forward the desired distance for
receiving the next impression.
72. is a finger key pivotted at 73 to a suitable projection on the base plate. One
end of this key is made hook shaped (Fig. 13.) and is adapted, when raised, to act
against a pin 74 on the pawl 60, so as to raise the latter out of gear with the feed
rack bar 61, when the platen frame is to be removed for inserting another sheet of
paper. The other end of the lever 72. is formed with a flat top or finger knob and.
is normally held in the position shewn by a coiled spring 75.
The spacing arrangement comprises a long flat wooden key 76, supported on two
vertical rods 77 arranged to slide through guide pieces 78 and 79 on the side
frame 2, and provided with coil springs 80. that act through suitable collars 81 on
the rods 77, to normally support the spacing key in the position shewn.
The lower ends of the rods 77 act on projecting parts 82 formed with the levers
arms 66 & 70, as shewn in Figs. 1. & 6, so that upon each depression of the
spacing key 76, the lever 62 will be operated and the platen 9 moved longitudinally
through a space equal to the pitch of the teeth on the feed bar 61, thus providing
a space between successive words.
With the construction of machine described, when the shifting keys 16 & 17 are
free, only the character at the inner end of each type block will produce an
impression on the paper carried by the paper cylinder or platen, the middle
character of each type block being brought into action by depressing the shifting
key 16, and the outer character of each type block by depressing the shifting
key 17. In this way, each of the ordinary keys 40 is caused to represent three
characters, which are marked on the key and either of which can be used at will.
In the machine shewn, there are 27 type keys each indicating three characters
or 81 characters in all, the impression produced by any one of which is visible to
the operator as soon as the corresponding type lever 29 has regained its normal
position and the platen 9 with paper has moved into position to receive the next
impression.
The platen is provided with any suitable means for imparting an intermittent

page_text: step by step motion thereto for forming successive lines of impressions. Also the
machine is provided with an audible indicator such as a bell 95, operated in any
well known or convenient manner for indicating when the platen is near the end of
its printing stroke or travel.
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 writing machine, the combination of a paper cylinder capable of
being moved in a direction at right angles to its axis so that it can be caused to
take up one or other of several predetermined positions, means for moving the said
cylinder into each of said positions, and a series of type blocks each provided with
characters equal in number to that of the positions into which the said cylinder can
be moved and connected to the corresponding type operating lever through a
flexible or spring connection, the arrangement being such that either of the
characters on a type block can at will be caused to produce an impression on
material carried by the cylinder substantially as herein described.
2. A type writing machine of the kind referred to in the preceding claim in
which the type levers carrying the type blocks, are arranged in two series on
opposite sides of the cylinder and there is provided a centering device adapted to
bring each of the type blocks, when depressed into a central vertical position above
the said cylinder substantially as herein described.
3. In a type writing machine, the combination with a paper cylinder and a
centering guide above the same, of type levers provided with type blocks carried
by flexible or spring plates, springs for holding the said type levers in their normal
and raised position, key levers and keys arranged above the said type levers, and
tension wires connected the said type and key levers, the arrangement being such
that the last character impressed can be seen when the type lever has been returned
to its normal position without moving the said cylinder, substantially as herein
described.
4. In a type writing machine of the kind referred to in Claim 1, the combination
with the paper cylinder, of feeding mechanism comprising a rack bar carried by
the adjustable frame in which the paper cylinder is mounted, a pawl pivotted to
the permanent part of the machine and of sufficient width to engage the rack
bar in each position of the cylinder, and lever mechanism substantially as
