PROVIDIONAL DE MOLTIVATION
Improvements in Washing and other Boiler Lids and Flues, for
Disposing of Surplus Steam and the like.
JOHN LOVING Market Place Belper, Ironmonger, and HERBERT WHITE Cluster
Buildings Belper Estate Foreman, both in the County of Derby, do hereby declare
the nature of this invention to be as follows:-
The object of our invention is to provide an improved apparatus for Collecting
and disposing of Surplus Steam generated in Boilers used for Washing, Brewing,
and other boiling purposes and the like, by making the Surplus Steam to pass
directly from the Boiler thro' a tube or tubes into either the smoke or other flue,
or into the open air; and thus prevent it coming back into the Building.
In carrying out our invention we construct a ring or frame of either, Iron, Steel
or other suitable material, which fits into, and on the top of the Boiler to allow
a lid or cover in one or more sections to work thereon; the said lid or cover being
operated by a handle or handles, lever, balance or other arrangement, and so
arranged that the aforementioned lid or cover, shall be practically steam tight,
when fixed and closed on the Boiler, (in some cases we may use Indiarubber or
other suitable material for the purpose.)
On the top, or sides of the lid or cover we connect the inlet end of an oblique
tube or tubes thereto by means of either rivets, Bolts and nuts, or other suitable
attachments, to fasten them together, the outlet end being fixed and secured into
the smoke or other flue, or into the open air; between the inlet and outlet ends
of the tube or tubes, we arrange to have either an adjustable damper, stop tap, or
valve, to shut off, or regulate the passage of surplus steam from the Boiler to the
smoke or other flue, the aforesaid lid or cover is made of suitable shape and material.
In some cases we arrange to use the oblique tube or tubes, made preferably of
earthenware or other suitable material, without the aforementioned Boiler lid,
or cover; by letting the inlet end of the tube or tubes project over the edge of
the Boiler; we arrange to have an adjustable damper, stop tap, or valve fixed
between the inlet and outlet ends to regulate the passage of the surplus steam;
In this case the usual wooden lid is cut to fit the inlet end of tube.
This invention is intended to be used or applied to either existing, or newly
erected Boilers.

Disposing of Surplus Steam and the like.
I, JOHN LOVING, of Market Place, Ironmonger, and HERBERT WHITE, of Cluster
Buildings, Estate Foreman, both of Belper, in the County of Derby. do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following state-
ment:-
This Ivention has for its chief object the provision of simple and effective means
for disposing of the surplus steam generated in boilers used for washing brewing,
and other purposes.
In order that our invention and the method of carrying the same into effect may
be the more readily understood we append hereunto two sheets of explanatory
drawings to be hereinafter referred to.-
On sheet 1 Figure 1 is a sectional elevation and Figure 2 a plan illustrating
the application of our invention to an ordinary domestic washing boiler or copper.
On sheet 2 Figure 3 is a sectional elevation representing an application of our
invention to a boiler or copper provided with an ordinary lid or cover, whilst
Figure 4 is a similar view representing a further modified application of our in-
vention.
The same reference letters in the different views indicate the same parts.
Referring to Figures 1 and 2 we employ an iron, steel, or other frame ring such
as A, preferably of a right angle section, which fits within and upon the upper
part of the boiler B to form a working and supporting base for the sectional or
one part lid or cover C which is provided with a handle C. On one part or section
of the lid we form or attach a tubular projection D over which fits the lower end
of the inclined tube E, the upper end of the tube E being fixed within the flue
wall F. We provide a damper such as G for the purpose of closing the passage
through the tube E or for regulating the extent of opening.
The lid or cover C is preferably made in parts or sections; as shown at Figures 1
and 2 it is composed of 3 or more pieces of plate so shaped and arranged that they
together form the conical top as illustrated. One or more of the section or
segments, (one being the segment to which the tube E is attached), are bolted or
otherwise secured to the base ring A, whilst the other segments are arranged to
rotate upon the stem or bolt of the handle C, such bolt serving to connect the whole
of the segments together at their upper ends), to an extent sufficient to expose one
half or nearly the half of the upper end of the boiler. Such open position of the
movable segments is shown at Figure 2, the opening into the boiler extending the
circular distance a.
When the segmental lid is completely closed as in Figure 1 and the damper is
open the steam will pass away to the chimney flue or to the external atmosphere
by way of the tube I, (or by closing the damper the steam may be retained) and
when the lid is open as in Figure 2, the greater part of the steam will still be 4
carried away through the said flue by the action of the chimney draught. When
but one section of the lid is open the whole of the steam will be carried away by
the chimney draught.
We preferably make the segmental cover of such dimensions that it can be fitted
within the boiler when not in use, and an ordinary flat cover can then be placed 4
over the boiler top to serve as a shelf, a table, or the like, as with ordinary coppers.
The projecting steam flue or tube E is then supported by an adjustable leg, tie,
or strut, e shown by dotted lines at Figure 1.

page_text: To prevent any down draught or fall of soot or dirt into the boiler we sometimes
provide a soot chamber H (with or without an inclined bottom) below the flue
mouth of the tube E, with a return opening as H into the flue.
In the arrangement shown at Figure 3 we employ an inclined steam tube E in
combination with an ordinary flat copper lid J which is cut away at the side
adjacent to the lower end of the tube E to fit against the tube; or the lower end
of the tube can be provided with lateral extensions fitting over a portion of the
boiler top, and thus enabling a cover to be employed having a flat side which simply
abuts against the lateral extensions from the tube E. The closed end soot
chamber His provided with a side clearing door as h, whilst the tube or steam
flue E is fitted with a sliding damper or valve as G¹.
In the arrangements shown at Figure 4 the wood lid K is of a right angle forma-
tion, and covers only one half of the boiler top, the other half being covered by the
metallic or earthenware dome part L to which is attached the steam tube or flue E.
We make our improved steam flues of tubes for service with existing or new
boilers or coppers with ordinary lids, preferably from earthenware, but we do not
limit ourselves to such material.
Instead of one we sometimes employ two or more steam tubes or flues and we
make other modifications in the application of our invention to meet varying
services or requirements. In large boilers we may use weighted or other levers,
or chains and weights to open or close the sections.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. The improved means for disposing of the surplus steam from washing and
other boilers arranged substantially as described and as illustrated.
2. The combination with a washing or other boiler of an inclined tube or flue
having its lower end projecting over the top of the boiler and its upper end opening
into the chimney flue or into the external atmosphere, substantially as described
and as illustrated.
3. A segmental lid or cover for a washing or other boiler having parts arranged
to permit of opening and closing of the boiler top without complete removal of
the lid or cover substantially as described.
4. The combination comprising a washing or other boiler lid or cover, or a part
of such lid or cover having a projection or socket as D fitting within, or upon the
lower end of a steam tube as E, substantially as described and as illustrated at
Figures 1, 2, and 4.
5. The combination with the inclined steam tube or flue for a washing or other
boiler, of a damper or valve and of means for intercepting any soot or down draught
substantially as described.
