SCHLESINGER, Merchant, of 120 Cheapside E.C. HENRY ALFRED JEUNE,
Merchant, 39 Seething Lane E.C. all in or near London, do hereby declare the '
nature of this invention to be as follows:-
A type writer actuated by a lever, which when placed to an index brings
forward the corresponding character of a type disk, to impress the paper placed
beneath, and by a downward movement the above-mentioned lever causes the type
to print, and at the same time moves the paper carriage forward a space to prepare
a vacant space for the next letter.
In order that the invention may be more clearly understood the principal parts
of the mechanism are hereafter described.
An index lever for indexing.
A suspension lever for impressing the type.
A curved lever for actuating the paper carriage.
The type disk is composed of spring metal, slit into divisions, upon the end of
each division and underneath the same a character is fixed.
The type disk is fixed beneath the upper framework and revolves upon a
spindle. The spindle passes through the framework and terminates upon the top
with a cog wheel.
The "index lever" which extends to the index, terminates in a semi-circular
toothed rack, the teeth of which actuate the cogs of the type disk.
Beneath the framework is placed the "suspension lever" which is held in
suspension by a spring attached to the framework. Beneath this lever is
placed the "curved lever" which rests upon an armature of the paper bearing
carriage.
"
Through the centre of the axle of the semi-circular toothed rack of the
"index lever is placed a movable metal bar, which rests upon an armature of
the "suspension lever."
In front of the machine and level with the cog wheel of the disk, is a semi-
circular index, which corresponds with the characters upon the type disk.
The action of the mechanism is therefore as follows:-
The "index lever" is moved on the index to the character required. By a
downward movement the lever presses the metal bar which passes through the
semicircular toothed rack of the lever, to the suspension lever, and impresses
a character of the type disk upon the paper beneath, the same movement presses
down the "curved lever" which acting upon an armature of the paper carriage
moves it forward a space sideways.
The paper carriage rests upon the pedestal of the machine. It is furnished
with a toothed rack on the side facing the operator.. An armature is placed in
front and separated from the paper carriage, from which armature depends a
vertical bar which engages with the teeth on the rack and moves the paper
carriage forward.

We, WILLIAM EDGECOMBE, Warehouseman of 95 Bow Road, E., WILLIAM
EDWARD ELLIS Traveller, of 50 Cobden Road, Leytonstone, Essex, HERMANN
SCHLESINGER, Merchant, of 120 Cheapside, E.C., and HENRY ALFRED JEUNE,
Drug Merchant of 39 Seething Lane Tower Street, all in or near London, 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 a typewriter without a finger board, the action of
which is operated by a hand-lever called the index lever, which lever is moved to
and fro on a quadrant-shaped bar, on which the letters or characters are
engraved. At the same time the further end of the lever which carries a
segmental toothed rack rotates a pinion attached to the vertical spindle of a disk,
on the under face of which are the corresponding types or characters for printing
or writing on the paper. Attached to said hand-lever is a vertical printing rod
for depressing the said disk at the right moment and causing it to print the
required letter or character on the paper. This printing rod is caused to act by
depressing the hand-lever, which also operates a small curved lever, which imparts
a forward motion to the paper carriage.
We will now describe the invention with reference to the accompanying
drawings, in which
Fig. 1 shows a plan view of our type-writer.
Fig. 2 shows a front elevation, partly in section, of Fig. 1.
Fig. 3 shows a side elevation, partly in section, of Fig. 1.
Fig. 4 shows a front elevation of the actuating mechanism for pushing the paper
carriage forward one space, every time a letter is printed.
Fig. 5 shows a back view of Fig. 4, with the toothed rack in section. The
dotted lines indicate the varying positions of the several parts while being
operated.
Fig. 6 shows an end view of Fig. 5, with rack shown in dotted lines, and exhibits
the cam y, for throwing the actuating mechanism of the paper carriage out of gear
with the toothed rack.
Fig. 7 shows a plan view of the bar m, Fig. 4.
Fig. 8 shows a plan view of the curved lever k, Fig. 4. a, is the frame of our
type-writer. al, is the quadrant shaped index bar on which is engraved or
attached printed letters of the alphabet, figures or characters a², is the base or
stand. a, a, are hinges to permit the frame a, index and printing mechanism to
be lifted up and inspected if requisite. b, is the index lever provided with a
pointer b', Fig. 3, for indicating the letter of the alphabet to be next used. 6, is
another short lever connected to b, at 63. This forms the fulcrum of the lever b,
by means of which the printing apparatus is operated. The short lever 6², is
fastened on to the toothed segment rack c.
c, is a toothed segment rack operated through the medium of the index lever b.
This wheel, gears with a toothed pinion d, to the spindle of which is attached the
type disk e. c, is the prolonged centre support of the rack c, on which support is
mounted a guide-bearing c², for keeping the index lever in b, in place and also
assisting to operate the rack c. c, Fig. 3, is a recoil spring which returns lever b,
to its original position. a, is a pinion mounted on spindle d¹, gearing with segment
rack c.
e, Figs. 1 and 3 is the metal circular plate of the type disk mounted on
the lower end of the spindle d', which runs in a bearing formed in the frame a.
e, e', are spaces the number of which correspond to the number of characters on
the index a', formed or cut round the periphery of the metal plate e, of the type

page_text: disk. These slots permit the printing lever ', to pass through them and press
down one of the divided segments e³, of the lower plate e³, of the type disk e, and
thereby impress the rubber characters or figures which are fastened to the under
si.le of the metal disk e², on the paper carried by the paper carriage beneath.
The lower plate e³, is formed of spring metal split into sections, each of which
carries ou its under side a character or sign corresponding to one of those on the
bar a¹. One of these sections is cut out to represent a blank space such as that
required after a word or between two words. f, is the inking roller and is kept in
contact with the face of the type by the spring f¹.
rack c.
9, Fig. 3, is a spindle passing through and sliding in the centre of segment
This spindle when the index lever b is pressed down also presses down a
small arm g', (which we propose to call the printing lever) and this arm passing
lownwards through one of the spaces in the type disk causes the type to print on
the paper beneath. 92, is a small recoil spring which returns the printing lever g²,
to its original position. h, is a small curved arm which is pivotted at h², and is
operated by a small stud h³, on its side engaging the printing lever g'. This
movement operates the mechanism for pushing the paper carriage sideways one.
tooth or space by means of a small striker h³, pivotted on the end of the arm h,
which presses down the lever k. k, Figs. 2, 4 and 5, is a large angular lever,
fulcrummed at l, on standard ', by means of which the paper carriage is moved
forward. k, Fig. 5, is a small triangular stud formed on the lower extremity of
the lever k, which engages with the teeth of the rack on the paper carriage. m, is
a straight arm pivotted at m', on to the lever k. is the hooked end of the
arm m, engaging with the teeth of the rack p, on the paper carriage. n', n¹, are
two small projecting guide-cheeks forming a small fork for keeping the bar m, in
place. o, is a small pin projecting from one of the cheeks n', so as to enable the
hooked end n of the bar m, to be thrown out of gear with the teeth of the rack p,
when required.
n,
o, is another small pin projecting from the lower end of the lever k, so as to
enable the triangular pawl or stud k¹, to be put out of gear with the teeth of the
rack p, when requisite. 1, Figs. 1 and 6 is a small cam which engages with
pins o', and throws the paper carriage actuating mechanism out of gear with the
rack p. 9, is a handle to cam q.. r, Fig. 2, is a recoil spring to return the
lever k, to its original position. s, is the paper carriage. s, is the paper roller.
83, is a tension roller. t, t, are wires forming the paper holders. u, u, are friction
rollers between which the paper carriage s, runs. v, is a lever with gong v, to warn
the operator when the paper carriage has reached its limit of travel.
Sinall lug on the carriage touches the upper end of the lever v, the bell rings.
w, is an upright for supporting index a'.
The operation of our machine is as follows:-
When a
The index lever b, is first moved round the index a', to the letter which is
wanted. This brings the corresponding letter on the type disk e, under the
printing lever 9, and over the paper. The index lever bis then pressed downwards
by the fingers and the letter is impressed on the paper resting on the paper
carriage. At the same time that the above is being printed the curved arm h, is
forced down and the striker ³, on the lower end of same presses down the large
lever k. The movement of this lever k, raises the hooked end n of the arm m, out
of gear with the teeth of rack p, and at the same time the cranked end k³, of
lever k draws the arm m, to the left and the hooked end n, then falls again by its
own weight into gear with the next left hand tooth of the rack p. The rising
action of the lever m, is obtained from the curved part x, of the lever k, and this
action is facilitated by means of a small stop pin y, (in the standard ) which
prevents the arm m from descending too low when the lever k, falls and no longer
supports it.
While the foregoing movement is taking place the triangular pawl or stud k¹,
Figs. 4, 5, 6 and 8, is lowered out of gear with the rack p.
On the fingers being taken off the index lever b, the striker ³, is taken off the

page_text: lever k, and the recoil of the spring r, raises the lever and with it the triangular
pawl, the chisel or sloping edge of which propels the paper carriage sideways.
On the paper carriage reaching its full limit of travel, the cam g, is turned to
the position shewn in dotted lines in Fig. 1, thus throwing the actuating mechanism
out of gear with the rack p. The paper carriage can then be moved back again
to the starting point and the tension roller s³, of the paper carriage, can be turned
to a fresh line on the paper by the handle provided, or may be regulated by any
well known means.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
