that is to say:
(1) A frame A B wherein can slide upon guides from right to left and vice vers
the plate Cupon which the sheets, cardboards or the like to be printed on are
arranged;
(2) The writing apparatus proper which slides in the perpendicular direction to
the movement of the plate.
This apparatus is formed of a base E upon which two vertical supports S S₁ are
fixed. In these supports can turn and move down a horizontal shaft D which is
ordinarily held in a raised position by means of springs. On this shaft are fixed
three, four or more typographic discs H H₁ H, H³, at the periphery of which are
arranged the various signs, that is to say the letters, numbers and the like.
The arrangement, which serves to bring the signs on the discs downwards and to
print with them, is constituted by a bevel gear FT whose velocity ratio is about 1
to 4. This gear is formed of a toothed sector T and of the toothed pinion F
fixed on the shaft D. The system of gearing is connected with this shaft and can
be lowered with it when the typographic discs are lowered for the printing. The
toothed sector of the horizontal wheel T 18 pivoted at T' above the shaft and is
actuated by a lever I which 18 connected with the sector so that the lever
and sector will be turned together. This lever carries the single key L' of the
machine.
The lever L which is united with the sector can turn and lower the shaft and its
discs by means of the following arrangement. The extremity M of the lever
terminates below in a circular arc N fixed to the frame of the machine, whilst the
other arm N' of the lever passes below the circular arc R on which the various
characters or signs are marked. A pointer connected with the lever marks upon
he circular arc R the letters, numbers or other signs to be printed, for it turns
with the lever, being maintained in the same vertical plane with the latter.

page_text: Below the circular arc R is arranged a circular comb S, with the teeth of which
engages the knife-edge of the lever in correspondence with the various signs to
be printed, for the purpose of ensuring a perfect operation of the machine. With
the same object and for preventing the discs from turning during the lowering,
on the side of one of the discs are arranged pins Y in correspondence with the
vatious signs, and below is placed near this disc a met illic piece having a double
guide slot with which engages the pin corresponding to the sign to be printed.
With this arrangement each character to be printed is guided during its downward
movement and cannot be displaced during the lowering of the system
For printing it is sufficient to turn the lever L until the pointer d 15 upon
the desired sign, when this has been obtained the key L' is pressed, the shaft D
aud discs II II' being lowered, thus obtaining the desired impression.
The forward movement of the plate carrying the sheets is obtained by the
downward and return movements of the shaft D, use being made of the following
arrangement During its downward movement the shaft pushes below against the
rod K arranged by the side of one of its supports, and this rod pressing upon
the spring bai Vactuates the levers and the pawl 9 which engages with
the rack g arranged below the plate. When the shaft is raised again with the
typographic discs the levers by means of the pawly displace the plate to an
extent corresponding to a tooth of the rack. By pressing the knob P which
actuates the levels u directly, the plate is displaced independently of the
movement of the printing device. By keeping the button P lowered the raok q'
is disengaged from its pawly and the plate C can then be moved back by hand t
its ouiginal position or to any point of its movement. Accordingly the button P
19 acted upon when the extremity of a line has been reached and the following line
is to be printed.
For moving the printing discs perpendicularly to the duection in which the
plate is displaced for the purpose of obtaining spaces between the lines, which
spaces may be equal or variable, use is made of the screw V along which the
printing apparatus will be displaced when this screw is turned; in lieu of this
Feren a system of pawl and rack may be employed such as that hereinbefore
described for the displacement of the plate.
Ink is supplied to the characters on the typographic discs by means of small
rollers G G with which the outer surfaces of the discs are in contact
The described arrangement having a single key may be replaced by an
arrangement having several keys (Figures 4 and 5). In this case a definite
single sign corresponds to each hey. Accordingly instead of the bevel gear upon
the shaft of the discs is keyed a pinion D₁ (Figure 4) whose length is proportional
to the number of keys of the machine. Upon two lateral shafts 0 0' and parallel
to the main shaft are arranged toothed vertical sectors whose number
corresponds to the number of the keys, but with a number of teeth varying
from one sector to the other. These sectors are independent of each other and
turn freely upon the respective shafts. Each of the sectors is connected through
the medium of a small rod to the corresponding lever Z Z pivoted upon the
opposite shaft
Each lever possesses a key with the pointer for the sign which
corresponds to it. It is understood that the number of teeth of each sector
is such that with a constant rotation for all the sectors the printing discs nie
turned until the sign corresponding to cach key shall be below.
It will be readily seen that when in this arrangement any key is pressed the
printing discs will turn so that the characters to be printed correspond to the
desired line. Then the whole system is lowered in its supports by the action of
the key lever and the impressiou is obtained as in the preceding arrangement.
The perfect operation of the machine is ensured in this case by means of a
stop K with which each lever is provided. This stop serves to limit the rotation
of the sector, for in its movement it will come against a projection K' arranged
in a corresponding position on the pinion in the same vertical plane. The same

page_text: pinion has a very definite and invariable position of rest to which it returns after
each impression.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what mannet the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
First. A type-writing machine designed for printing at the same time two, three
o more copies, characterized by the use of two, three or more discs, at the
periphery of which are arranged the characters or signs to be printed, the said
discs being secured on the same shaft, to which rotary movement is transmitted by
means of a bevel wheel mounted upon the said shaft and gearing with a horizontal
sector or toothed wheel connected with a single lever acted upon for printing.
Second. In a type-witing machine having a single key the arrangement by
which, when pressing the lever, the shaft, discs and bevel gear are lowered after
the lever has been tuined until the pointer is placed upon the desired sign, for the
purpose of obtaining the impression.
Third. In a type-writing machine the arrangement of levers and pawls by means
of which the sheets to be printed upon are displaced in two directions perpendicular
to each other.
Fourth. In a ty pe-wilting machine the arrangement of pins and a slotted
piece for preventing any displacement of the character or sign to be printed
during the lowering of the whole system.
Fifth. A type-writing machine printing at the same time two, three or more
copies, characterized by the arrangement of several discs, at the periphery of
which are provided the characters or signs to be painted, the said discs being
mounted finly on the same shaft, upon which is also keyed a toothed pinion
gearing with several toothed sectors, each of the sectors corresponding to one of the
sigus to be printed.
Sixth. In the type-witing machine set forth in the fifth claum the airangement
of two lateral shafts O O₁ parallel to the shaft of the discs upon which the toothed
sectors are provided, each sector having a number of teeth which varies in
accordance with the character or sign, and being actuated by means of a key level
and a connecting rod articulated to the sector.
Seventh. In the type-writing machine set forth in the fifth claim the device by
means of which the shaft and discs after each impression are moved back to
an invariable original position, for the purpose of ensuring a perfect operation of
the machine.
Eighth. In the type-writing machine set forth in the fifth claim the arrangements
described in the second, third and fourth claims for the purpose of effecting the
lowering of the system of discs, displacing the sheets after each impression and
preventing any displacement of the character or sign during the lowering of the
system.
