the Commissioners of Patents, with his Petition,, on the. 5th June

I, MEINRAD THEILER, Telegraphic and Scientific Instrument Maker,
of 156, Barnsbury Road, Islington, Middlesex, do hereby declare the
nature of the said Invention for "NEW OR IMPROVED MACHINES OR APPARATUS
FOR PUNCHING OR PREPARING STRIPS OF PAPER OR OTHER SUITABLE MATERIAL FOR
THE AUTOMATICAL TRANSMISSION OF TELEGRAPHIC MESSAGES AND FOR OTHER
PURPOSES; AND IMPROVEMENTS IN APPARATUS FOR REGULATING THE SPEED OF
TELEGRAPHIC INSTRUMENTS, PARTS OF WHICH INVENTION AS INDICATED ABOVE
ARE ALSO APPLICABLE FOR OTHER PURPOSES," to be as follows:-
My Invention consists, firstly, of a punching instrument for cutting
either similar or different shaped holes into a strip of paper or other
material, either for the purpose of automatical transmission of electric
messages or for any other purpose.
Secondly, of a machine to facilitate the working of the above instrument;.
if considerable power be required, and for producing a powerful motion:
at will for any other purpose.
Thirdly,, of a mechanism for. regulating the speed of transmitting, and

page_text: recording instruments as well as that of any other train of wheels and
pinions or endless screw.
The first instrument presents three keys, two of them intended to cut,
on being depressed, their cither similar or different marks, composing
the Morse's or other alphabet, while the third is merely to move the
.paper on for producing the spaces between the letters and words. The
paper, wound upon a coil or disc, passes through a pair of rollers which,
on being turned round draw the paper forward between themselves,
similar to a Morse's instrument. On the axis of one of these rollers: a
double ratched wheel is mounted, the one part intended to drive the
rollers by and the other to stop them. The driving of the rollers step.
by step is effected by a lever carrying a clique near its end in the
following manner:-Each of the keys of the instrument on being depressed
moves that lever down also, whereby its clique glides. over the teeth of the
ratched wheel and drops in by the pressure of a little spring. When
the key is left it is raised by a spring while another spring acts upon the
clique lever, thereby pushing the paper rollers forward. The two cutters.
are so connected with the clique lever as to cut their respective marks.
at the downward motion of the keys. On rising of the keys, springs,
drive the cutters out of their holes first, after which the elique drives
the rollers forward. If the two marks composing the alphabet are of
different length, as it is with the Morse's system, the keys are made to
depress the clique lever to a different depth, thereby taking a different
number of teeth of the wheel and consequently pushing the rollers
on more or less according to the length of the mark cut. At the
extremity of that same clique lever a catch is formed, dropping into
the second part of the ratched whicel, and thereby preventing the rollers.
to turn by momentum further than required. Another catch is applied
to prevent the backward motion of the rollers.
:
The second part of my Invention consists of a machine to be worked
by a treadle or other motive power to facilitate the working of the above
described punching instrument and to produce a powerful motion at
will for any other purpose by a slight touch of a key. The motion of
the crank axle, to which a fly wheel is mounted, is transmitted in proper
velocity to a spindle upon which one or several ratched or in other
shape cut wheels are fitted which, on the machine being set in motion,
present a magazine or source of mechanical power. Three of these
wheels, which I call the primary wheels, are required for working

page_text: my punching instrument. In proper distance of each of these wheels a
secondary wheel is pivoted so as to be driven round by the primary
one. These secondary wheels are dedented, that is to say, a few
teeth are taken off, thus allowing of their standing still while
the primary wheels are turning round. Springs tend to drive the
secondary wheels into gear with the primaries, but this is prevented
by a catch for cach wheel. These catches are connected with keys,
similar to those of a piano, in such, manner as to release one of the
wheels whenever its corresponding key is depressed. This so released
wheel is instantly driven into gear and turned round until its dedent
detaches it again, at, which moment it is stopped by a second catch
attached at the same axle as the first. The key on being left rises:
by a spring, at same time releasing that second catch and setting the
first in. By this motion of the catches the dedented wheel is allowed.
to advance a short step, but not so much as to come into gear with the
primary wheel, it is merely in its normal position then. To cusure an
instantaneous gear, and to prevent shokes by the wheels meeting point.
to point, one or more of the teeth of the secondary wheels are made.
yielding, either by spring or in any other suitable way, and the following
tooth or teeth are shortened and regulated so as to drop in when the
yielding teeth are point to point with the primary wheels. I also make
one or both pivot beds yielding by spring, or I connect them with the
keys direct, thus shifting the dedents into gear with the primaries by
the keys themselves. In this case I make the dedents hold in gear by
their revolving into closed proximity of the primary wheels. Where
there is little power required, I also apply plain rollers instead of either
the primary or the secondary wheels or of both of them, made or covered
with a frictionary material, thus obtaining the motion of the secondaries
mainly or exclusively by friction. In this case a cavity cut out of the
secondaries serves to detache them from the primaries when at
rest.
This machine affords a ready means of a powerful circular motion at
will either for a full revolution or part of it. For working the above
described punching instrument, and for many other purposes however,
the circular motion of the dedentals must be transformed into a lincar
action, either by crank, excentric, or lever. These can be planted above
the punching instrument so as to push the kevs, or below them, so as

page_text: The third part of my Invention is a mechanism for regulating the
speed of transmitting and recording instruments, as well as that of any
other train required to run at a uniform and adjustable speed. This
regulator consists of a fly mounted upon the last or any suitable pinion
or endless screw of the train, which fly can be shifted along its axis
by a lever. On the same pinion or endless screw a disc of ivory or
other light material is mounted, into which slots are cut to allow the
shifting of the fly through the disc. When, therefore, that axis is turned
by the train, the fly and the disc turn with it, the shifting lever acting
upon a collar disc at the end of the fly so as to let it turn freely.
Close behind that ivory disc, and concentrical with the axis of the fly
a box is screwed to the framework, deep enough to allow the shifting
of the fly to the end of its axis. By shifting the fly part of it is immersed
into the box, therein finding no resistance, since no air can enter at
center and consequently non will escape at the circumference. Therefore
only the projecting part of the fly is working, and as this part is alterablé
the speed must alter accordingly, or rather reversedly. By making the
axis of the fly long enough, any difference of speed can be obtained.
For a more accurate shifting of the fly the shifting lever is acted upon
by a spiral shaped disc, the axle of which, carrying an index outside
the frame moving over a dial that is marked with suitable numbers ar
signals.
