Improvements in or relating to Compound Engines.
1 SAMUL WOLFSON of Zaschinick Germany, Engineer do hereby declare the
nature of this invention to be as follows:-
I provide an arrangement consisting of a series of tubes placed in a closed vessel
filled with water through which the steam coming from the cylinder passes the water
in the closed vessel will condense this steam passing through the tubes and a constantly
acting feed pump connected with the tubes forces this steam water again into the
boiler or generator. The water in the closed vessel will gradually become heated over
the boiling point and produce a tension a little under the pressure in the tubes and as
soon as this tension reaches a certain degree a second piston may be driven by this
steam. The generator heated by the fire being supplied with water obtained by
distillation small and winding tubes may be employed without danger or inconvenience
from incrustation. In the closed vessel or low pressure boiler any incrustation will
be on the outside of the tubes and easily removed. The closed vessel or low
pressure boiler is acting here in the place of a receiver of a compound engine
with the advantage that it furnishes a feed water of high temperature for the
generator.
By this arrangement I can also drive crank shafts mounted at right angles to
each other or in any necessary position and independently of each other.

page_text: IDAMUL WOLFSON of 64 St. Georges Road Warwick Square, London S. W. 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 has for its object the perfect utilisation of the heat contained in the
exhaust steam, in a second or low pressure boiler.
As the steam coming from the boiler contains a great proportion of water which is
conducted to the steam engine a large amount of heat will be consumed in heating
this water to the temperature of the steam. To remedy this I have made an
arrangement by which the feeding water obtained by condensation containing the
above mentioned water is reconducted at as high a temperature as possible to the
generator. For that purpose the steam coming from the engine leaves the cylinder
not with the pressure of the atmosphere only but with half the pressure of the live
steam. This passes through a series of tubes placed in a closed vessel filled with
water. The water will condense the steam passing through the tubes and a continually.
acting feed pump in connection with the tubes passes the steam water again into the
boiler or generator. The cold water in the vessel or low pressure boiler will be heated
over the boiling point and produce a certain tension a little under the pressure in the
tubes. As soon as this reaches a certain degree a second cylinder may be supplied
and its piston driven by this steam. I thus obtain a kind of compound Engine.
The stroke intervals of both cylinders are quite independent of each other and
therefor one can construct in this manner a system of Engines working with two
cranks working at a right angle with each other. Thus I obtain a perfect utilization
-of the heat. The temperature of the fresh steam does not differ much from that of
the steam coming from the first cylinder and the water is pressed by the feed pump.
into the generator with a temperature corresponding to the tension of the steam
Jonly-partly used. The generator heated directly by the fire is continually fed with
water produced by distillation. One can therefor employ generators with narrow
winding tubes without danger or inconvenience from fur. The evaporating water in
the vessel or low pressure boiler must also be completed by cold water through a
feeding apparatus and therefor fur will be formed in this vessel. However the
sediment will. be, deposited on the outside of the tubes and can be easily taken away.
In the low pressure, boiler the steam is formed by the heat of the steam passing
through the tubes the difference between the tension in the low pressure boiler
and the tension of the steam passing through the tubes is dependent on the amount
of heating surface of the tubes in proportion to the quantity of the condensed
steam. The full heat of the steam coming from-the first cylinder being employed
in the formation of steam, in the low pressure boiler while the tension in this
boiler is a little lower, the quantity of this steam is therefore larger.

with this advantage that it furnishes a feeding water of high temperature for the
generator.
On the accompanying sheet of drawings A is a winding tube generator heated
by fire. The steam is conducted by the tube c to the cylinder C. The steam
coming from this cylinder passes through the tube 6 into the chamber K and
thence into the tubes 6 placed in the condenser or low pressure boiler B₁ heating
the water in it. The condensed steam water is collected in the vessel W whence it
is taken by the feed pump E through the tube e and reconducted to the generator A
through the tube a. The steam formed in the low pressure boiler B' is conducted
by the tube 6 into the second cylinder D where it is acting like the steam coming
directly from the first cylinder, w¹ and w² are water glasses to indicate the height of
the water in the vessels W and B', is a feeding tube for the low pressure boiler
and is a reserve feeding tube for the vessel W.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The combination of the generator A the tube c the Cylinder C connecting
therewith the tube the low pressure boiler B¹ connecting therewith the water
vessel W at the lower end of the boiler the tubes e and a and the pump E
connected therewith to return the condensed water to the generator all substantially
as described.
2. The combination of the cylinders C and D and their connecting tubes with the
generator A the low pressure boiler B¹ having a water vessel or chamber as described
and the tubes and pump to return the condensed water to the generator and the
generator substantially as described.
