PROVISIONAL SPECIFICATION.
An Improved Registering Steam Gauge or Indicator.
I, THEOBALD WENDLING of Mannheim in the German Empire, Printer, do hereby
declare the nature of this invention to be as follows:-
The apparatus of this invention is adapted for intercalation in the pipe through
which the steam of which the pressure is to be gauged or indicated passes. It consists
of a valve casing fitted inside with a flap valve lifting up and descending so as to
cause a horizontal hollow spindle with which it is in connection, to oscillate on
bearings. The hollow spindle passes through the valve casing to the outside thereof where
it is in connection with a manometric device consisting of two cylinders in each of
which is a movable piston the respective piston rods being in connection with an
arrangement of jointed levers or rods carrying a pencil marker which upon the
movement backwards or forwards of the pistons is caused to move over and mark the
surface of a drum carried on the top of the valve casing. When steam in its passage
through the valve casing, lifts up the valve flap at the same time passing through the
hollow spindle to the manometric device on the outside of the valve casing, the pistons
are thereby moved according to the pressure of the steam and their movement carried
over through the levers to the marking pencil.

COMPLETE SPECIFICATION.
An Improved Registering Steam Gauge or Indicator.
I, THEOBALD WENDLING of Mannheim in the German Empire, Printer, 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 apparatus for measuring or gauging steam or other
compressed gases, the pressure of the same for the time being, in its passage by
a valve; and also the movement of the valve itself being utilised for the purpose.
The invention consists in an arrangement of a hollow oscillating spindle in
connection through an elbow tube with the flap of a valve. At one end of the hollow
spindle outside the casing of the apparatus is fixed a manometric appliance from
which motion is transmitted through levers to a marking pencil by the action
of the steam or gas passing through a hollow spindle and by the oscillation of
this latter.
In the accompanying drawing, Fig. 1 is a side view partly in section of the
apparatus of this invention. Fig. 2 a horizontal section thereof through line A-B of
Fig. 1 and Fig. 3 a vertical section through line C-D of Fig. 2.
1 and 2 are
respectively the inlet and outlet passages of the apparatus separated from each other
by valve d the rising and falling flap- or disc of which is hored through at the centre
and carries in this bore an elbow tube 6¹ connected to hollow oscillating spindle
mounted on bearings in casing of apparatus. kare manometers the pistons e of
which are linked to levers f which belong to a series or system of levers by
which a marking pencil is carried or moved over a registering sheet which it marks.
Upon the passage of steam or gas by valve d the flap of the same rises causing
hollow spindle & to turn in its bearings which movement actuates the series of levers
arrying the marking pencil. Further, steam or gas as the case may be, passes

page_text: through either tube b¹ and hollow spindle b to the manometers & and also acts upon
the levers and marking pencil.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :
In a registering steam gauge or indicator in which the pencil or marker is actuated
on the one hand by the pressure at the time being of the steam passing by a valve
and on the other hand simultaneously by the motion of the flap or body of the said
valve, the arrangement of a hollow oscillating spindle on which, outside the casing
of the apparatus a manometric appliance in connection with the levers through which
the pencil or marker is operated which manometric appliance is acted upon by the
steam which is to be measured or gauged passing through the hollow spindle,
substantially as described and shewn.
