CONNECTED WITH STEAM AND WATER JET MOTORS, PARTLY APPLICABLE TO FLUID
METERS." (A communication from abroad by Eduard Jacob Hahn, Director of the
Allgemeiner Volks-Wirthschafts-Verein, in Frankfort on the Maine, in the German
Empire.)
The apparatus constructed according to this Invention consists, firstly, of a
regulating or filling appliance in the form of a cylinder closed at both ends, of a
float appliance, and of a regulating cock or slide or other valve; secondly, of a steam
boiler, and thirdly, of a driving wheel or turbine.
The action of the apparatus is as follows:-Water from the boiler is by the steam
pressure in same by a pipe conveyed on to the driving wheel which it propels.
When it has given off its force it collects at the foot of the wheel in a collecting
vessel, and flows by a pipe and a back pressure valve into the filling appliance
aforesaid. The position of the regulating cock enables the air and vapours in the
filling appliance to go out to the driving wheel on which they act usefully; hereby
is also effected an equilization of the pressure at the filling appliance and the driving
wheel, so that the water can flow from the collecting vessel to the filling appliance
as above stated.
By the water now flowing into the filling appliance a lever on the cock is raised
by means of the float, a counterweight is thrown over and thereby the communi-
cation between the filling appliance and the boiler suddenly established through
the cock and pipe, and a second back pressure valve which is released. As the level
of the apparatus is higher than the water level in the boiler (which is of especial
importance) the water in the filling appliance flows down to the boiler..

page_text: The float then drops because of its weight and throws the counterweight over to
the other side by means of the lever, and thereby the communication between the
boiler and the filling appliance is interrupted; the operation described is then
repeated.
For taking up the vapours from the driving wheel a condensing vessel is used
wherein they are condensed, and then flow back and act on the vanes of the driving
wheel.
The outflow from the boiler may also be regulated by a valve or cock suitable
for the boiler pressure, or by a governor receiving its motion from the driving
wheel.
If the filling appliance and cock and float appliance are to be used for measuring
fluids it is connected with an air vessel instead of with a boiler; the back pressure
valves are not used, the openings are closed, and the regulating cock placed at the
lower instead of the upper part of the filling appliance in such a manner that the
water flows in and out through it as the steam used for a boiler feeding apparatus
or motor.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Peter Jensen in the Great Seal Patent Office on the 2nd July 1880.
PETER JENSEN, of 33, Chancery Lane, London. "IMPROVEMENTS IN AND
CONNECTED WITH STEAM AND WATER JET MOTORS, PARTLY APPLICABLE TO FLUID
METERS." (A communication from abroad by Eduard Jacob Hahn, Director of the
Allgemeiner Volks- Wirthschafts-Verein, in Frankfort on the Maine, in the German
Empire.)
The apparatus constructed according to this Invention consists, firstly, of a
regulating or filling appliance in the form of a cylinder closed at both ends, of
a float appliance, and of a regulating cock or slide or other valve; secondly, of a
steam boiler, and thirdly, of a driving wheel or turbine.
And in order that this Invention may be more fully understood, I will now
describe the same with reference to the accompanying Drawings, in which I have
shewn the aforesaid regulating and filling appliance in connection with a steam
boiler and a turbine to serve as a motor, but it may also be applied for the automatic
feeding of boilers as a fluid meter and for other kindred purposes.
Figure 1 is a general elevation of the combined apparatus partly in section, and
Figure 2, a plan view of same. A is a steam boiler, and B the apparatus proper or
filling and regulating appliance, consisting essentially of a cylinder a, a float b, and
a regulating cock o; the latter is shewn separately and to a larger scale in
Figures 5 and 6, which are respectively end view and plan section of same, while
Figures 7, 8, 9, 10, 10, 11, 11, 12, and 12ª, are sections through A, B, Figure 6,
representing various positions of the plug of the cock. Figure 6ª is part sectional
end view of a slightly modified form of cock, and Figure 6b plan section through.

page_text: 'same: Slide valves may obviously be used as exact equivalents for the cocks
herein described. The steam boiler may be of any suitable or well known
construction whatever; D is a turbine of any suitable or well known construction.
The action of the apparatus is as follows:-Water from the boiler A is by the
steam pressure in same by a pipe e conveyed on to the driving wheel or turbine D,
which it propels. When it has given off its force it collects at the foot of the
wheel in a collecting vessel f, and flows by a pipe g and a back pressure valve d
into the filling appliance B aforesaid. The position of the regulating cock c is now
that shewn in Figure 7, in which it enables the air and vapours in the filling
appliance B to go out by the pipe h to the driving wheel D, on which they act
usefully; hereby is also effected an equalisation of the pressure at the filling
appliance B and the driving wheel D, so that the water can flow from the collecting
vesself to the filling appliance as above stated.
By the water now flowing into the filling appliance B a lever i on the cock c is
raised by means of the float b and a rod b¹ connected to the lever i, a counterweight
lever k on the plug of the cock c is thrown over, and thereby the communication
between the filling appliance, and the boiler suddenly established through the
cock c and pipe n, and a second back pressure valve d is released; then and as the
bottom of the apparatus B is higher than the water level in the boiler A (which is
of especial importance) the water in the filling appliance B flows down to the.
boiler A by the pipe m and back pressure valve d¹; the cock c is now in the position
shewn in Figure 9.
The float b meanwhile drops because of its weight, and throws the counter-
weight lever k over to the other side by means of the rod b¹ and lever i, and thereby
the communication between the boiler A and the filling appliance B is interrupted;
the operation described is then repeated. The opening and closing or changing of
position of the cock c may be done by spring or other force instead of a weight as
described.
For taking up the vapours from the driving wheel D a condensing vessel E is
used; wherein the vapours are condensed, and then flow back and act on the vanes
of the driving wheel D.
The outflow from the boiler may also be regulated by a valve or cock suitable for
the boiler pressure, or by a governor receiving its motion from the driving wheel,
as will be presently explained. If the filling appliance. B and cock c and float
appliance bare to be used for measuring fluids it is connected with an air vessel
instead of with a boiler; the back pressure valves d and d¹ are not used, the
openings are closed and the regulating cock c placed at the lower instead of the
upper part of the filling appliance in such a manner that the water flows in and out
through it as the steam used for a boiler feeding apparatus or motor. When used
as a high pressure meter or as a motor with a steam boiler it should be connected
with an air vessel..
Figure 3 is a part section of a cylinder B with float b, where the float rod b¹
passes up through a hole in the cover without any stuffing box, and where the
upper end of the rod b' and the lever i are enclosed in a casing i¹.
Figure 3 is a vertical section, and Figure 4 plan of a modified arrangement, in
which the cock c is placed on one side of the vessel B instead of on the top of
the cover.
Figure 13 is a vertical section through a vertical steam boiler with pendant tubes
in the fire box, and having two cylinders B arranged on its top; Figure 14 is a
side view of same, and Figure 15 a plan section through the lower part of the
cylinders B, and the pipes connected thereto; Figure 16 is a plan section through
the boiler. Each cylinder B has a float b, and these latter are by rods 6' connected
to two levers or a double lever i for actuating the plug of the cock c, which has a
counter weighted lever kas before. The pipes and m connecting respectively
with the turbine and with the water space of the boiler A are fitted with back
pressure valves & and d', as in the previously described arrangements; n is the pipe
between the cock c and the upper part of the boiler. The out flow pipe e from

page_text: the boiler A is fitted with an equilibrium or other throttle valve, which is regulated
by a governor e¹, which receives its motion from the turbine driving wheel.
Figure 17 is a vertical section through a combined cock or slide valve e of a
nodified form; Figures 18 and 19 are end views of same, showing by the thick
dotted lines two different positions of the counterweight lever k. The levers i, 2ª,
are actuated by the float rods b₁, 61; the counterweight lever kactuates towards each
side a carrier peg p, which passes through a segment slot in the cover r, and is fixed
in a revolving disc 8 which effects the changes in the action in a similar manner to
that of the plug c in Figs. 5 and 6; n is the pipe leading to the top of the boiler
A, and h the pipe leading to the turbine. The other four pipes connect the two
cylinders B with the water space in the boiler and with the bottom compartment F
of the turbine. There is a plate q which covers the slot in the cover r, and is
pressed against it to make a joint by means of a helical spring on each carrier
peg p.
And having thus described and ascertained the nature of this Invention
communicated to me, I declare that I claim,-
Firstly. The vessel B placed above the highest water level of a steam boiler
connected thereto (or as when applied as a fluid meter exposed to the pressure in
an air vessel) and combined with cock or slide valve appliance c, all operating
substantially as described.
Secondly. The vessel B in combination with the cock or slide appliance c, and
turbine with
the pipes and valves for connecting it with a steam boiler and with
condenser, and actuating the turbine, substantially in the manner described.
Thirdly. The various constructions of the cock or slide appliance c, as described
and illustrated in the accompanying Drawings.
In witness whereof, I, the said Peter Jensen, have hereunto set my hand and
seal, this First day of July, in the year of our Lord One thousand eight
hundred and eighty.
