This Invention has for its object to enable vessels or chambers to be effectually
heated by means of steam supplied to jackets surrounding such vessels without
subjecting the vessels or jackets to any material pressure whilst at the same time
ensuring that a slight pressure of steam shall always be maintained within the
jackets and avoiding the blowing off of steam from them freely into the open air.
When a series of vessels cach surrounded by its own steam jacket is to be
heated by steam from a steam boiler I lead off from the steam pipe which passes
from the boiler a branch pipe into each steam jacket and I carry up this branch
pipe to some distance above the bottom of the steam jacket so that no water pro-
duced by the condensation of steam in the jacket may pass back into it-upon
each branch pipe I also provide a cock by which the amount of steam admitted to
the jacket can be controlled. From the bottom of each steam jacket I lead a pipe
downwards. The lower end of this pipe I contract and make to dip down nearly
to the bottom of a small spherical or other formed vessel into which water produced
by the condensation of steam running off from the stean jacket may be collected.
This vessel I form with a tubular neck extending-upwards from it and surrounding
the upper end of the contracted portion of the descending pipe-from this tubular
neck a branch pipe is led off through which all water flowing into the condensed
water collecting vessel may flow away freely after this vessel is filled. The column
of water between the bottom of the pipe which leads from the steam jacket and
this overflow pipe ensures a slight pressure of steam in each steam jacket and
prevents steam from blowing off freely from them.

I, CHARLES JONES of 2 Lower Whitecross Street in the City of London Builder
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 to enable vessels or chambers to be effectually
heated by means of steam supplied to jackets surrounding such vessels without
subjecting the vessels or jackets to any material pressure whilst at the same time
ensuring that a slight pressure of steam shall always be maintained within the
jackets and avoiding the blowing off of steam from them freely into the open air.
When a series of vessels each surrounded by its own steam jacket is to be
heated by steam from a steam boiler I lead off from the steam pipe which passes
from the boiler a branch pipe into each steam jacket and I carry up this branch
pipe to some distance above the bottom of the steam jacket so that no water pro-
duced by the condensation of steam in the jacket may pass back into it-upon each
branch pipe I also provide a cock by which the amount of steam admitted to the
jacket can be controlled. .From the bottom of each steam jacket I lead a pipe
downwards. The lower end of this pipe I contract and make to dip down nearly
to the bottom of a small spherical or other formed vessel into which water produced
by the condensation of steam running off from the steam jacket may be collected.
This vessel I form with a tubular neck extending upwards from it and surrounding
the upper end of the contracted portion of the descending pipe-from this tubular
neck a branch pipe is led off through which all water flowing into the condensed
water collecting vessel may flow away freely after this vessel is filled. The column
of water between the bottom of the pipe which leads from the steam jacket and
this overflow pipe ensures a slight pressure of steam in each steam jacket and
prevents steam from blowing off freely from them.
The drawing annexed shews apparatus arranged as above described.
Figure 1 shews a small steam boiler and a steam pipe led off from it for con-
veying steam to the steam jackets of two vessels which are to be heated-any
desired number of vessels might be heated from the same steam pipe-the vessels
shewn in the drawings are such as are commonly used for holding a supply of
boiling water which can be drawn off as required by a tap.

A is the steam boiler B the steam pipe leading therefrom--C C branch steam
pipes led up into the steam jackets of the two vessels D-on each of these branch
pipes is a tap D by which the amount of steam admitted to each jacket may be
regulated EE are pipes led off from the bottom of each steam jacket and made to
dip into a spherical or other vessel F from the top of which is an overflow to which
a waste pipe is secured through which excess of steam may blow off and water
produced by the condensation of steam in the steam jacket flow away.
The way in which I form the vessel F and secure it to the end of one of the
outlet pipes E is shewn at Figure 2. G is a screw union piece to screw on to the

page_text: end of the pipes E-H is a ring union securing a piece I to the piece G. The lower
end of the piece I has screwed into it part of the enlarged upper end of a pipe J.
On to the other part of this enlarged end is screwed the end of a neck K which
projects up from the spherical vessel L-This neck has a branch pipe M standing
out from it to which the waste pipe N is coupled. The condensed water collecting
in the vessel L seals its end and as above explained maintains always a slight
pressure of steam in the steam jackets of the vessels D whilst at the same time it
acts as a safety valve ensuring that these vessels shall never be subjected to
excessive pressure.
The same arrangement of apparatus may be used when beating all kinds of
vessels or chambers with steam heated jackets.
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 apparatus substantially as described for heating vessels
or chambers with steam heated jackets.
2. The apparatus for preventing steam from blowing off too freely from the
steam jackets substantially as described and shewn at Figure 2.
