I, ARNOLD BUDENBERG, of the Firm of Schäffer and Budenberg, of Man-
5-chester, in the County of Lancaster, do hereby declare the nature of the said.
Invention for "IMPROVEMENTS IN APPARATUS FOR INDICATING AND REGISTERING

page_text: THE PRESSURE OF STEAM IN STEAM GENERATORS, AND THE PRESSURE IN HYDRAULIC
PRESSES AND OTHER VESSELS OR CHAMBERS, WHICH IMPROVEMENTS ARE ALSO APPLICABLE
TO INDICATING AND REGISTERING PRESSURE AND VACUUM IN STEAM ENGINES, THE
VACUUM IN CONDENSING APPARATUS; ALSO TO INDICATING AND REGISTERING THE
COMBINED PRESSURE OF THE STEAM OR OTHER POWER EMPLOYED TO GIVE MOTION TO
AN ENGINE, AND THE SPEED OF SUCH ENGINE OR OTHER MACHINERY; ALSO TO
INDICATING AND REGISTERING BAROMETRICAL VARIATIONS," a communication, to
be as follows:-
In carrying out these improvements I employ a hollow tube which may be
twisted or otherwise bent, but which by preference is bent into a curved form.
One end of this tube is fixed whilst the other end is formed by expansion or
contraction of the curve or other form to give motion to a pointer to indicate
on a dial as in the Bourbon indicators.
According to my improvements for indicating and registering the pressure of
steam in steam generators the fixed end of the tube is open to the interior of the
generator so that the steam may flow and exert its pressure therein, the other end
of the tube or some part of it distant from its fixed end in addition to its capability
for actuating a pointer to a dial is also connected by a link or other suitable means
to leverage actuating a holder for a pencil or other marker so as to cause that
pencil or other maker to move to or fro with variations in the form of the tube.
The pencil or other marker marks on a sheet of paper or other surface upon a
cylinder which is caused to revolve-by clockwork in a direction transversely ta
the direction of motion of the marker, so that if the surface marked is regularly
divided by lines parallel to the axis of the cylinder variations of pressure may
be regularily registered during any given time during the rotation of the
cylinder. Other pressures or vacuums may be indicated and registered in
like manner. For indicating the speed of engines or other machinery whilst
indicating and registering the pressure of the steam or other power- giving
motion thereto, I employ the motion of the engine or other machinery to
cause by band and wheelwork or otherwise a cylinder to revolve and complete,
say one revolution in a given time relatively to the desired speed of such
engine or machinery. The pressure of the steam or other power is registered
as before described on the paper or other surface applied to or forming part
of the drum or cylinder, which will then be arranged to complete one revolution
or part revolution in a given time, but if the engine or other machinery works
faster or slower, then the drum will either perform more than or not complete
the desired extent of revolution. For indicating and registering pressure and
vacuum in steam engines part of the apparatus may work as an apparatus
known as McNaughts' and other similar steam engine indicators, but instead.

page_text: of a piston and spiral spring the hollow tube above referred to is applied to
effect the relative motion. Similar apparatus is applicable to indicating and
registering barometrical variations, but in this case the curved tube will be
closed. By these means indications of the respective conditions for the time may
always be visible, whilst such conditions showing the variations during a given
time will be recorded.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Arnold Budenberg in the Great Seal Patent Office on the
3rd February 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARNOLD
BUDENBERG, of the Firm of Schäffer and Budenberg, of Manchester, in the
County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of August, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirty-first year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Arnold Budenberg, Her special licence that I, the said Arnold Budenberg, my
executors, administrators, and assigns, or such others as I, the said Arnold
Budenberg, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS FOR
INDICATING AND REGISTERING THE PRESSURE OF STEAM IN STEAM. GENERATORS, AND
THE PRESSURE IN HYDRAULIC PRESSES AND OTHER VESSELS OR CHAMBERS, WHICH
IMPROVEMENTS ARE ALSO APPLICABLE TO INDICATING AND REGISTERING PRESSURE
AND VACUUM IN STEAM ENGINES, THE VACUUM IN CONDENSING APPARATUS; ALSO TO
INDICATING AND REGISTERING THE COMBINED PRESSURE OF THE STEAM OR OTHER
POWER EMPLOYED TO GIVE MOTION TO AN ENGINE, AND THE SPEED OF SUCH ENGINE
OR OTHER MACHINERY; ALSO TO INDICATING AND REGISTERING BAROMETRICAL
VARIATIONS," a communication to me from abroad by Bernhard August Schäffer
and Christian Friedrich Budenberg, of Buckau, Magdeburg, in the Kingdom
of Prussia, upon the condition (amongst others) that I, the said Arnold
Budenberg, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same

page_text: may flow and exert its pressure therein, the other or free end 6¹ of this tube b
(or it may be some other part of it distant from its fixed end), in addition to its
capability as heretofore to actuate a pointer c, is also connected by a rod d to
the double lever e, which is capable of turning on the fixed axis or fulcrum e¹,
and at its other end is connected by pin joint e to the connecting rods f, which
at their other ends are connected by pin joint g¹ to the outer end of the com-
bined levers g which turn upon the fixed axis or stud g, by which in the
movement of the levers e a parallel motion will be obtained to a marker f¹
carried by the connecting rods f. The marker may be an ordinary pencil
carried in a socket affixed to the arms for other suitable pointer adapted to
produce a mark on paper or other material moving against it. It is however
preferred to employ paper prepared, such as that used in the manufacture of
what are called "metallic memorandum books," with a'marker similar to that
used for writing on the paper in such books.
Figure 3 shows a portion of a form of paper such as that preferred to be
used. In this case markings on the borizontal lines indicate the degrees of
pressure for the time exerted, and the position of those markings in relation to
the vertical lines the times of such pressures. As shown, the paper is applied
around the surface of a cylinder h which is supported by its axis h' so as to be
capable of revolving freely in the framing i, and it has continuous rotary
motion given to it by means of clockwork movement applied in the case j
acting by the axis j¹ and arm on the stud h² from the cylinder h; but in
place of the clockwork movement being applied in a separate case it may be
applied within the cylinder h, or that cylinder may otherwise bave continuous
and uniform motion given to it; and in place of the paper or other surface
receiving the markings from a suitable marker being affixed for the time
around the surface of a cylinder h it may be simply caused to travel past the
pointer or marker on a supporting surface whilst being wound from one roller
on to another or otherwise having the required progressive motion imparted
to it; and the marker in place of being applied to a system of levers e, f, g,
may be simply carried by an arm from the rod d, or it may be otherwise
operated from the bent tube b: By these means variations of pressure of the
steam in the boiler or other generator may be regularly indicated and regis-
tered during any given time. In like manner may the pressure in hydraulic
presses and other vessels or chambers be registered and indicated, as well as
variations in the pressure and vacuum in steam engines and the vacuum in
condensing apparatus. For indicating and registering pressure and vacuum
in steam engines part of the apparatus may work as in apparatus known as
McNaughts' and other similar steam engine indicators; but in place of a

page_text: piston and spiral spring the hollow tube b above referred to is applied to effect
the relative motion.
Figure 4 shows a portion of a front view, Figure 5 a horizontal view with
some of the parts in section, and Figure 6 shows a section through the lines
(1) (1) of Figure 5 of apparatus according to the Invention for indicating the
combined pressure of the steam or other power employed to give motion to
an engine, and also simultaneously the speed of such engine or other machinery
thereby moved. As shown some of the parts are similar to those shown and
described in respect of Figures 1 and 2, and they are marked with the same
letters of reference; but in this case in place of the cylinder or other surface
adapted to carry forward the paper or other surface to receive the desired
markings or indications being moved forward by clockwork movement it is
moved forward by the action of the machinery set in motion. For this pur-
pose the outer end of the lever is connected by pin joint to a link from au
eccentric or other suitable moving part of the engine or other machinery set
in motion, so that in the motion of such engine or other machinery a to-and-fro
motion may be imparted to the outer end of the lever 7; and in order that the
extent of such motion may be varied as desired the outer end of the lever lis
.slotted for the adjustment therein of the connecting pin of the connecting rod
giving motion to it. The lever / is affixed to the hollow shaft ¹ which turns
upon without being fixed to the spindle m, and this hollow shaft carries the
dise or hollow plate 12 which by a series of pins 13 carries a series of lugs or
pawls which in the movement of the lever in one direction clips fast on to -
the cylindrical surface n¹ of the collar n to give partial rotary motion to that
cylinder, and by that collar being made fast to the axis m to give a like partial
rotation to that shaft at each of such motions of the lever l. When the lever
moves back in the opposite direction other lugs or pawls o' turning on pins o²
carried by the case o enclosing these parts act on the surface n' to prevent its
back motion. The lugs and o¹ are borne upon by the ring springs s and t.
Upon the axis m is formed or affixed the screw thread m³, the teeth of which
take into teeth around the periphery of the drum h, or it may be other
cylinder or carrier for actuating the paper or other surface to receive the
desired markings. In place of leverage a band, or belt, or wheelwork, or
other actuating means from the engine or machinery set in motion may act
on to give the desired movement to the drum or other surface carrying the
surface to receive the markings. By these means may the speed of engines
or other machinery be indicated and registered whilst indicating and regis-
tering the pressure of the steam or other power for the time employed to give
motion to such engines or other machinery.

page_text: Apparatus such as described in respect of Figures 1 and 2 by the tube b
being in connection with a closed chamber hermetically sealed is applicable to
indicating and regulating barometrical variations.
Having thus described the Invention as communicated to me I would have
it understood that I do not confine myself to the precise arrangement of parts
as shown and described, as these may be varied without departing from the
peculiar character of the Invention, and fingers or other pointers or numbers
or other indications may be applied to indicate the revolutions of shafts and
movements to be ascertained; but what I do claim is, the adaptation or com-
bination of means acting in manner and for the purposes substantially as
herein described.
In witness whereof, I, the said Arnold Budenberg, have hereunto set my
hand and seal, this Third day of February, in the year of our Lord
One thousand eight hundred and sixty-eight.
ARNOLD BUDENBERG. (L.S.)
