improvements in Cements or Compositions applicable for Caulking Gas
Retorts, Furnaces, Boilers, Fipes, and the like, and otherwise as a
Refractory Material.
I, SAMUEL JOSEPH WOODHOUSE, of 16, Wood View Terrace, Dewsbury Road,
Leeds in the County of York, Gas Engineer, do hereby declare the nature of this
invention to be as follows:-
My invention relates to a non-porous and non-shrinkable cement for caulking
the joints in gas retorts, furnaces, pipes and the like.
My improved caulking cement is composed of cast iron borings, fireclay, and
glass refuse (or pottery refuse), preferably in equal proportions with a smaller
proportion of lime or other suitable binding material, the whole being finely
ground and thoroughly mixed. When required for use it is mixed with water
to form a paste,
On setting it forms an absolutely non-porous and non-shrinkable joint, so pre-
venting waste of gas, stean or water.
Any suitable glazing composition may be applied after the caulking operation.
If desired the cement may also be used for building forge furnaces, or for
other purposes where great heat-resisting qualities are necessary.

Improvements in Cements or Compositions applicable for Caulking Gas
Retorts, Furnaces, Boilers, Pipes, and the like, and otherwise as a
Refractory Material.
I, SAMUEL JOSEPH WOODHOUSE, of 16, Wood View Terrace, Dewsbury Road,
Leeds, in the County of York, Working Gas Engineer, 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:-
My invention relates to a cement or composition to be used mainly for caulking
the joints in gas retorts, furnaces, pipes, and the like, the object being to produce
a cement or composition which shall be non-porous and non-shrinkable at all
temperatures and under all conditions and which shall be particularly adapted
to resist an intense white heat.
When used in a gas manufacturing plant, as for instance for caulking the

page_text: interior of the retorts and for making the joints of the retort caps, mouth-pieces
and ascension pipes, a better quality of gas is produced by reason of such plant
being rendered perfectly air-tight, and all waste of gas in the retorts during manu-
facture is prevented. The said retorts, after being cleared of carbon and re-
caulked, are preferably glazed with a suitable glazing composition or liquor.
My improved cement or composition may also be used with advantage for steam
pipes and hydraulic joints; or it may be moulded into bricks blocks, or slabs
for building forge furnaces, and into melting crucibles for brass and steel works,
or it may be applied to other like purposes where great heat-resisting qualities
are necessary.
My improved cement or composition is composed of fireclay (raw or burnt),
cast iron (or cast iron and steel) borings, glass (or pottery) refuse, and lime (or
forge slag), the whole being ground to a fine powder and thoroughly mixed, pre-
ferably in about the following proportions:-
Fireclay -
Cast iron borings
Steel borings
Glass refuse
Forge slag
-
50 per cent.
25
per cent.
12
per cent. and
12
per cent.
I propose to slightly vary these proportions according to the degree of heat to
be sustained. Thus the proportions given are suitable for joints or parts which
are to be worked at a white heat, while for hydraulic and steam joints, or any
joints worked at comparatively low temperatures, the amount of fireclay and bor-
ings would be slightly increased the glass refuse and forge slag being corre-
spondingly decreased.
When required for use the cement or composition is mixed with water to form
a paste of suitable consistency, which when applied sets into an absolutely non-
porous, non-shrinking, and non-expanding mass.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim is:-
The non-porous and non-shrinkable cement or composition compounded sub-
stantially as specified and for the purposes set forth.
