Improvements in Typewriters.
I, FRANK LAMBERT, of 79-83, Washington Street, Brooklyn, New York, United
States of America, 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:--
My invention relates to improvements in typewriters such as described in the
Specification of my British Patent No. 22910 dated October 15th 1896 the type-
writer therein described has a single nutating disc key upon which all the
characters are marked a type ring being connected to this key so that when the
key is tilted a type on the surface of the type ring is brought into the line of
pressure over a platen. Bodily depression of the key brings the type into contact
with the printing surface on the platen, and the movement of the key actuates
releasing mechanism whereby the spring actuated paper carriage is caused to move
over a given space before the succeeding type is printed. I will describe my
present improvement with reference to the accompanying drawings of which:
Figure 1 is a side elevation of the machine. Figure 2 is a vertical section,
shewing in dotted lines the standard and working parts of the machine thrown
back. Figure 24 is a view of a detail, taken in the direction of the arrow d,
Figure 2. Figure 3 is a plan on line - of Figure 1, the key and associated
parts being omitted and the standard thrown back. Figure 4 is a sectional plan
on line of Figure 1. Figure 5 is a plan view of the base of the apparatus partly
in section. Figure 5* is a diagram. Figure 6 is a plan view of the central portion
of the multiple key. Figure 6* is a section of a portion of the key. Figure 7 is
a plan view of the supporting sleeve for the multiple key. Figure 8 is a plan
and Figure 8 a side elevation of the cam for shifting from one series of type to
another. Figure 9 is a plan view of the upper surface of the multiple key, the
resetting cap being in place. Figure 10 is an inverted plan of the key and type
ring. Figure 11 is a plan view of the inner side of the type ring. Figures 12
and 13 shew different forms of pressure points. Figures 14 to 19 and 31 to 35
are details relating to the feed mechanism. Figure 20 is a front elevation of the
paper carriage. Figures 21 to 26 are details of parts shewn in Figure 20; and
Figures 27 to 30 are views representing the inking pad.
The disc key 1, preferably of hard rubber and made as light as possible, has
designated on its upper surface pressure points, see Figure 9. These pressure
points may consist of buttons 6, Figure 12, having convex glass faces 7, or as
shewn in Figure 13 they may each consist of a pivoted button 8, the upper surface
of which may be flat or any other suitable shape. The button 8 lies in a radius
drawn from the centre of the key, and therefore if pressure is exerted on any part
of the surface of the button the pressure will be localized at its pivot and thus
move the key in the desired direction.
The key has a central socket. 9 resting and adapted to be tilted on a spherical
surface or ball 10. The rotation of the key on the ball is prevented by a pin 11
projecting from the ball 10 into a slot in the socket 9, Figure 2. The ball 10 is

page_text: bored, and passing over the upper end of a hollow rod 12, engages with the said
rod by a clutch device 150, formed with interlocking points on the lower part of
the ball 10 and on a shoulder on the rod 12. This rod 12 fits loosely in a support-
ing arm 13, and is retained therein by screws 126 screwed into the said arm 13,
Figures 1 and 7. These screws 126 may be adjusted so as to tilt the rod 12, which
is the central support of the key, to centre the key and type ring exactly in line
with a stop 30 hereinafter described.
Extending through the rod 12 is a smaller rod 15, threaded at its upper end,
onto which is screwed an inverted cup 16 which is surmounted with an ornamental
plate 17. The lower edge of the cup 16 is maintained against the upper surface of
the key by means of a spring 14 in the hollow rod 12 bearing at one end against
a shoulder in the rod, and, at the other end upon a nut 136 screwed onto the
lower end of the inner rod 15. A set screw 137, Figure 2, passes freely through
a slot of limited length in the rod 12 and is screwed laterally into the nut 136 and
prevents the rod 15 from turning in the nut; by loosening the set screw 137 the
rod 15 can be turned in the nut 136 thus permitting either the removal of the
cup 16 or the adjusting of the tension of the spring 14. The removal of the cup 16
permits of the key 1, arm 13 and type ring 3 being removed either for repairs or to
substitute other keys and type rings for a change of style of type, or for a change of
characters for different languages. By tightening the set screw 137 the nut 136
will be locked and so prevent the resetting cup from turning.
When the key is tilted, the side of the key which rises lifts the cup 16 against
the action of spring 14, and when the pressure is released, the spring acting on the
cup causes the key to return to its normal position. To prevent the key from rock-
ing when so tilted I make in the upper surface of the disc beneath the edge of
inverted cup 16, grooves or corrugations as shewn at 18 in Figures 6 and 6. These
corrugations correspond in number to the pressure points on the surface of the
key, and their relation to the several pressure points is such that lines drawn from
the centre of a pressure point and the centre of motion of the key will pass between
the elevated edges of the corrugations. Such lines are shewn in Figure 6 at 19,
Thus, when the key is tilted the cup bears on two points on opposite sides and
equally distant from the meridional plane of oscillation, and prevents rocking
of the key. The line or face of contact of the cup and key is below the centre of
nutation.
The clutch 150 is normally maintained closed by the spring actuated cup 16,
in whatever position it is moved but with a slight exertion the key 1 and ball 10
may be rotated, the clutch immediately locking the ball to the support. Refer-
ring to Figures 9 and 10, if the key and type ring are in such a position that the
characters are at right angles to the printed line, the characters will print at right
angles to the said printed line. If, however, the key and ball are rotated in either
direction one or more teeth of the clutch, so that the characters both on the key
and on the type ring assume a slanting position, to one side or the other, the out-
line of the character will be printed in a more or less angular position in reference
to the whole printed line, according to the amount of rotation given the key.
The word "sir" on Figure 3 represents the letters printed slanting
to the right, and the words "fifteen dollars" represent the letters printed slanting
to the left.
The type ring 3, Figure 10, is clamped in supporting arm 2. The lower convex
surface is struck from the centre of nutation, and is provided with series of type,
each series being formed of two or more preferably concentric rows in staggered
relation to each other as shewn, in order to reduce the extent of tilting of the key
and ring. If the outer circle of type on the type ring corresponds to the inner
circle of pressure points on the key, and the inner circle of type corresponds to the
outer circle of pressure points, the extent of tilting necessary to bring any of the
type of a series into printing position can be equalized. The concave interior of
the type ring, shewn in plan in Figure 11, and in section in Figure 2, is stepped
in three steps, recessed radially, the recesses in each step being alternately deep

page_text: and shallow. The shallow recesses in a step or circle correspond to the smaller
circle of type in the aforesaid series, and the deeper recesses correspond to the larger
circle in the series. Therefore, the three steps of recesses provide for six circles
of type, or three series of two circles each.
An
The sleeve 13, Figures 1 and 2, is connected to a sleeve 22 by an arm 21.
arm 23, pivoted at 24 to the standard 4, is forked, the ends of the forks being
pivoted to the sleeve 13 at 25. Arms or links 27 are pivoted at one end to the
sleeve 22 at 26 and at the other end to the standard 4 at 28. The effect of this
arrangement is to cause the key and type to move in a straight line when depressed.
A spiral spring 29 connects the arm 23 with the standard 4, to bring the said
arm 23, sleeve 13 and other coacting parts into normal position after the key has
been depressed. The stop pin 30 extends through the sleeve 22 and is adjustably
secured at its upper end in a cam 31. A spring 141 bearing between the cam 31
and the top of the sleeve 22, tends to move the stop 30 upward in the sleeve and
hold the cam against a fixed pin 32 in the arm 21. The co-operation of the recesses
of the interior of the type ring with the stop pin 30 is as follows: When the key
is tilted to bring the type into the printing line P L, Figure 1, a recess corre-
sponding to that type will receive the end of the stop pin 30 and stop the type ring.
By means of an arm 151, Figure S, the cam 31 may be rotated, for shifting from
one series of type to another. This cam 31, see also Figure 8, is so constructed
as to enable the stop-pin 30 to be adjusted and held at three different elevations,
so as to adapt it for entering any one of the three series of recesses in the type
ring.
The standard 4 is pivoted directly to the base 5, consequently the standard and
all the parts carried thereby, may be thrown back as indicated in dotted lines in
Figure 2, thus completely exposing the paper upon which the printing is being
done. The normal angular position of the standard 4 with reference to the base,
hence the relative alignment of the central axis of the stop 30 with the printing
block 51, is regulated by an adjusting screw and check nut 140, which is seated
in a spring box 61 and bears against a projection from the standard 4 as shewn in
Figures 2 and 18.
Referring to Figures 27 to 30, a double forked support 34 has its forks 35
pivoted directly to the standard 4, and between the forks 36 an annular pad
holder 37 is diametrically pivoted. A thin annular plate 38, having an inking
pad 40 of absorbent material attached to its upper side, is detachably secured to
the pad holder 37, by inserting projections 39 on the plate 38 through openings
in the pad holder 37 and bending them over, as shewn in Figure 27. A leaf
spring 41 secured on the under side of the support 34 has an aperture 42 opposite
a central opening in the pad holder 37, and directly in the line of impression.
This spring serves as a shield to prevent any type other than the one to be printed,
from touching the paper. Figure 28 shews a contracted opening 44 in the plate 38,
whereby this plate may act as a shield, and the leaf spring 41 may be dispensed
with. The diametrical pivoting of the pad holder permits the pad to automatically
adjust itself to the face of the type ring and equalize the pressure at all points.
An index 43 projecting from the plate 37, Figures 2, 3, 27 and 28 locates the exact
printing point on the paper in any position of the carriage when the standard is
thrown back.
When the machine is operated at fast speed, the inertia and the action of the
resetting spring 14 causes a vibration of the key and type ring when they resume
their normal position, and to prevent or minimise this vibration I provide a brake
or dampener. For this purpose I prefer to use the inking pad, as the type ring
has the greatest arc of motion, therefore I allow the inking pad support 34 a prefer-
ably free upward action and provide a leaf spring 45, secured to the standard 4
at 46, to press the pad against the type ring. The relative tension of this spring 45
is adjusted by a screw 47 in proper relation to the resetting spring 14 adjustable
by the nut 136.
The base 5 has an inclined table 49 to support the paper during erasures, etc.,

page_text: the said table extending the entire length of the base, and being provided with a
plate 50 laid off in suitable divisions. Each standard 55 and 56 of the movable
carriage has a pointer or index 121 122, Figures 3, 4 and 20. The scale plate 50
is naked as shewn in Figure 4, the pointer 121 designating from the beginning
of the line to the fortieth space, and the pointer 122 designating from the fortieth
to the eightieth space, the pointer 122 beginning to indicate at the moment the
pointer 121 reaches its last space.
A block 51, Figures 1, 2 and 4, preferably of rubber, receives the impact of the
type. This block is seated in a screw 52 adjustable in the table 49 to adjust the
block 51 with reference to the type. When the standard 4 is properly adjusted,
the imaginary printing line P L should pass through the centre of the block 5.1,
and at right angles to the face of the block, so that the face of the type is parallel
to the face of the block when coming down upon it.
Guides or ways 53 in the base 5, Figures 1 and 5, receive the bottom plate 54
of the carriage. The standards 55 and 56, mounted on the plate 54, carry a shaft 57
of the paper roller 58 which may be rotated by means of a milled disc or wheel 59
fast on the end of the shaft 57 which is journaled in the standard 55, the other
end of the shaft being supported on an adjustable pivot screw 60 in the standard 56.
Referring to Figures 5 and 17 to 19, Figure 18 being a side elevation of
Figure 17, taken in direction of arrow e, and Figure 19 a section on line ff of
Figure 17, the spring barrel 61, secured to the base 5, contains a coiled spring 62,
one end of which is fastened to a pin 63 and the other end to the hub 64 of a
toothed wheel 65 journalled at 66 in the box C1 and also in the top plate of the
base 5. The toothed wheel 65 engages with a pinion 67 mounted on a pin 68 fast
in the box 61, and the pinion 67 engages with rack teeth 69 formed on the rear edge
of the carriage plate 54. The action of the spring 62, under tension, is to rotate
the wheel 65, and through the pinion 67 and rack 69, to move the plate 54 together
with the whole carriage and the roller 58 to the left in the drawing Figure 5. To
control this movement there is provided an escapement consisting of a pallet 78
Figures 31 and 32 and an escape wheel 71 fast to a pinion 72 which turns loosely
on a pin 70 mounted on the box 61. The pinion 72 engages the rack 69 and
participates in its motion.
The pallet 78 is attached to and controlled by a vertical rod 73, Figures 2, 4, 5, 31
and 32, extending up through the standard 4, and capable of a longitudinal sliding
motion. On the upper end of the rod 73 is a hub 74 having a bent arm 75, the
turned down end of which has an anti-friction ball 48 mounted thereon and rest-
ing upon the rear end upward projection 81 of the lever 23. A depression of the
key 1 raises this end of lever 23 and so raises the arm 75 and rod 73. Surround-
ing the rod 73 is a spring 76 secured at one end to the inner side of the standard 4,
Figure 2, and at its other end to an adjustable collar 77, fastened by set screw 125
on the rod 73. On the lower end of the rod 73 is the pallet 78 having two fingers 79
and 80, of different lengths, and bent as shewn in Figures 5 and 31. The longer
finger 79 of the pallet engaging with the escape wheel 71, normally prevents motion
being imparted to the carriage by the spring 62. When the rod 73 is raised by the
depression of the key and consequent lifting of the lever 23 the pallet 78 is raised
as shewn in dotted lines in Figure 31 and the escape wheel 71 is free to move
slightly forward until it engages with the shorter finger 80 of the pallet which has
been raised into line with the escape wheel 71. When pressure on the key is
relaxed, and lever 23 returns to its normal position the rod 73 is forced down-
ward by the spring 76; the finger 80 thus releases the escape wheel 71 which is
then free to move until its next tooth is stopped by the finger 79, thus moving
the carriage a unit space between the letters. The escapement mechanism is
operated as described either by depressing the key for printing or by pressing on
the spacer or plate 17 no type in the latter case being brought into position to
print. This escapement mechanism can be operated in the same way when the
standard 4 is thrown back as shewn in Figure 2, the pallet 78 still engaging with
the escape wheel 71. The axial line of the pivots 33 of the standard 4 is tangential

page_text: to the escape wheel 71 so that while the rod 73 may be inclined as indicated by
dotted lines in Figure 32 the relative engagement of the fingers with the escape
wheel is not changed.
The spring 76 acts by expansion and torsion to keep the pallet in engagement
with the escape wheel 71. A partial rotary motion of the rod 73 against the
tortional force is effected by pressing the arm 75 in the direction of the arrow k
Figure 2 by which motion the pallet 78 will be thrown out of engagement with
the escape wheel 71 and while heid out of engagement the carriage may be moved
by hand in either direction. This can be done in any position of the standard.
The extent of rotary motion of the rod 73 is limited by side walls 82. The tension
and torsion of the spring 76 is adjusted by loosening the set screw 125 and moving
the collar 77 into proper position. The engagement between the pallet 78 and the
escape wheel 71 is adjusted by loosening set screw 123 and turning or raising or
lowering the rod 73. A pin or wire may be inserted in a hole 124 at the upper end
of the rod 73, Figure 2 to move the rod.
Referring to Figure 18 the pin 70 carrying the pinion 72 and escape wheel 71,
is mounted eccentrically in a sleeve 170. By means of a lever 171 secured to the
sleeve 170, Figures 5*, 17, and 18 the sleeve 170 can be rotated, thereby shifting
the position of the center pin 70. Figure 5* is an enlarged diagrammatic view
representing a displacement of the center pin 70, and consequently the pinion, 72
without affecting the engagement of the pinion with rack 69. The cross feed of
the carriage being controlled by the escape wheel 71 the variation of the position
of the center of the escape wheel shifts the stopping position of this cross feed in
reference to the printing line P L. Therefore, if a character or word is printed and
then the carriage moved back to the starting position for the said character or
word, and the lever 171 moved to change the stopping position of the cross feed
and then the same character or word be again printed, it will not coincide with
the first printing but will be printed at the side thereof thus making the outline of
the character appear in double lines, as shown by the words "Commissioner" and
"Sir" on Figure 3. The distance between the double lines, will depend upon the
throw of the escape wheel, determined by the extent of movement given to the
lever 171.
The projection 81 on the line 23 and the inclined surface 181 thereon are so
formed that as soon as the rod 73 is lifted sufficiently to clear the finger 79 from
escape wheel 71 the ball 48 rides along the incline 181 and the opposing force
of the spring 76 is at once reduced, the rod 73 practically not being lifted further
by the continued rising of the rear end of the lever 23. Therefore the greatest
force necessary to bring the type into position to print is exerted at the beginning
only of the downward depression of the key, the further exertion to move the type
being minimised. This gives a pleasant touch important in a machine of this kind.
The force that would otherwise be necessary to overcome continued resistance is
now applied to the impressing of the type, thus greatly aiding in manifolding.
A stop 84, projecting from table 49, in the normal path of a catch 83, Figures 5
and 14, pivoted on the standard 56, prevents the rack 69 from accidentally run-
ning out of engagement with the pinion 67. When the carriage is to be removed
the catch S3 is thrown forward (to the left in Figure 14) out of the way of stops 84
and 85, Figure 5. The stop 85 is in the path of the standard 55 and prevents the
carriage from being pushed so far to the right as to be out of gear.
When the carriage is to be taken out of the machine and therefore the rack 69
removed from pinion 67 the spring 62 is prevented from unwinding by means of
a detent 86 pivotted on the pin 68, Figures 15 and 16 and dropping from the
plate 54, on which it normally rests by gravity, Figure 15, into engagement with
the teeth of the pinion 67 Figure 16. This prevents the rotation of the
pinion 67 and consequently of the gear wheel 65 and hub 64 to which the spring 62
is secured. When the rack 69 is out of engagement with the pinion 67, the tension
of the spring 62 can be adjusted by turning the pinion 67.
Instead of the detent SG I may use a cam 186, Figures 33 to 35, having an up-

page_text: wardly extending spring portion 187 with a downwardly bent tooth acting as a detent
to engage between the teeth of the pinion 67. A pin 188, passing through the
fixed centre pin CS, not only retains the cam 186 and the pinion 67 in place, but
acts on the spring tooth 187 as follows; when the rack 69 is leaving the pinion 67,
Figure 33, the standard 56 of the carriage comes in contact with a projection 189
on the cam 186 and partially rotates the cam, carrying the spring portion 187
under the pin 188, as shewn in Figure 35, and causing the tooth on this spring
portion to engage between the teeth of the pinion 67 to lock the same. When the
rack 69 again engages the pinion 67 it turns the pinion in the opposite way to the
force of the spring 62, and the pinion carries the spring tooth 187 and cam 186
with it until the spring portion is free from the pin 188, as shewn in Figure 34.
An upward projection 190 on the cam 186 coming in contact with the pin 188
limits the rotary motion of the cam 186 when the carriage is removed. With this
modification the catch 83 may be dispensed with.
In a recess 87 in the paper roll 58 is a bar 88, Figures 21 and 25, having a
flange 89 between which and the surface of the roller the edge of the paper is
inserted and the bar is then moved longitudinally in the recess 87, and by means of
a pin 91 passing through a hole in the roll 58 into a cam slot 90 in bar 88, the
bar is drawn into its recess, the flange 89 clamping the paper upon the surface of
the foller. The paper is wound upon the roller as the writing advances down the
sheet. Pins 94, Figure 20, engage in guide slots 92 and 93 in the bar 88 which
slots are enlarged so that the clamping action of the bar is controlled only by the
pin 91 and slot 90, consequently the flange 89 is always parallel with the roller and
clamps the paper with even pressure.
Upon a bar 95, supported in the standards 55 and 56 Figures
stop 96 adjustable along the bar and clamped by a screw 97.
and 20, is a
This stop by striking against a lug 98 on the standard 4, Figure 4, limits the
movement of the carriage.
A paper clip 99 carried by the bar 95 presses upon the top of the roller 58,
Figure 22 shows the blank (on a small scale) that forms this spring clip 99. The
triangular shaped portion 100 is bent and wound round the bar 95, Figures 4,
and 20, and a pin 101, passing through the bar 95 and the hole 102 in the end of
the triangular portion, maintains the clip in position. To adjust the tension of
the clip 99, the bar 95 is rotated thereby tightening or loosening the coil 100, the
bar 95 being secured by screws 103.
The device for rotating the roller, and producing the spacing of definite intervals
between the printed lines, is illustrated in Figures 20, 23, 24 and 26. On the
shaft of the roller 58 is a ratchet wheel 105 engaged by a pawl 106, carried on
a lever 107, which lever is pivotted to the standard 55 at 108, Figure 24, and has
in it a slot 109 through which the roller shaft 57 passes, 110 is a coiled spring
surrounding the roller shaft, one end of which spring bears against the pivot 108,
and the other end passes over a pin 111, which extends laterally from the pawl 106.
When the lever 107 is carried forward that is in the direction of the arrow m
Figure 24, the pawl 106 engaging with the teeth of the ratchet wheel 105 rotates
that wheel, and turns the roller 58 in a direction away from the operator. When
this movement of the lever 107 ceases, the ratchet wheel 105 is prevented from
turning by a spring 112, Figure 24, engaging with the teeth of the ratchet wheel
and the lever 107 is then thrown back to its original position by the coiled
spring 110, this return movement being permitted by the elongated slot 109,
and restricted by the right hand side of the said slot coming against the roller
shaft as shewn in Figure 24.
Surrounding the roller shaft is a sleeve 113 Figure 23, fast in the standard 55,
and shouldered as shewn at 114 Figure 23. Between the shoulder and the
standard 55 the sleeve is surrounded by a cam 115 which is free to rotate on the said
sleeve when moved by the handle 116. Upon the edge of the cam bears the pin 111
fast to the pawl 106. The extent of rotation of the cam 115 is limited by a
notch 117 in the lower part of the said cam through which notch passes the pivot

page_text: pin 108 of the lever 107. When the handle 116 is pushed down, as so to bring
the right hand side of the notch 117 against the pin 108, then the edge or corner 118
of the working face of the cam is carried to the right in Figure 24, so that the
pawl 106 is held out of contact with the teeth of the ratchet wheel 105 over such
a distance that when the pawl 106 descends and passes over the corner 118, the
pawl can then move only sufficiently to act on one tooth of the ratchet wheel and
so rotate the roller 58 a corresponding distance. When the handle 116 is moved
to its middle position as shewn in Figure 24 the pawl 106 is held up by the work-
ing face 118 over a certain less distance of its movement, so that when it falls into
engagement it is competent to work two teeth, and finally when the handle 116 is
raised to its full extent, the pawl 106 is held up out of engagement with the ratchet
for a still less period and when it falls is competent to operate three teeth. To
hold the cam in either one of its three positions and prevent accidental rotation,
the cam is countersunk as shewn at 119 in Figure 26, in three places. On the
outside of the standard 55 and carried by the bar 95 is a leaf spring 120 pressing
against a pin passing through a hole in the standard and entering the counter-
sunk 119 which is opposite the pin.
The screw 47, for adjusting the brake spring 45 passes out at the rear side of
the standard 4, and the bell is placed over the projecting end of the screw, and
secured by a thumb screw 128. To adjust the screw 47 and thereby the tension
of the spring 45, a slot 147 is formed in the outer end of the screw 47 in which slot
a feather projecting into the circular centre hole of the bell enters; therefore, by
turning the bell the screw is rotated, and when the tension of the brake spring 45
is properly adjusted, the thumb screw 128 is screwed down securing in permanent
position both the screw 47 and the bell 127.
Extending through the standard 4 is a forwardly inclined tubular opening 129,
Figures 1 and 4, in which is a steel ball 130, on the inner side of the standard a
projection 131 has a constricted aperture forming a seat in which the ball 130
normally rests. On bar 95 is an adjustable sliding piece 132 which may be secured
in any definite position by means of a set screw 133, Figure 4 and from which
projects a spiral spring 135. The piece 132 and the spiral spring are so set on
the bar 95 that as the carriage carrying the said bar moves, the spiral spring strikes
the projection 131 first and is deflected sidewise; then as it clears the side of the
projection it meets the ball 130 and the spring shoots the ball up through the
opening 129 causing it to strike the bell, after which the ball falls back by gravity
and resumes its normal position. The ball is practically a free hammer and no
adjustment between the hammer and bell is necessary to insure a proper sounding
of the bell.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed. I declare that what I
claim is: :-
1. In a typewriter a multiple key, a type ring controlled thereby, having on its
outer surface series of type, each series being formed of two or more circles of type,
each type in a series being on a different radius from the rest of the type in the
same series, the type ring having on its inner surface circles of radial recesses corre-
sponding in number to the said series, each circle having its recesses of varying
