IMPROVEMENTS IN CEMENT OR COMPOSITION FOR USE IN THE LAYING OF FLOORS AND PAVEMENT
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
1 ROGER LEIGH LOWE of the Britannia Works Worsley Road Farnworth in the
County of Lancaster Contractor do hereby declare the nature of the said invention
for "IMPROVEMENTS IN CEMENT OR COMPOSITION FOR USE IN THE LAYING OF
FLOORS AND PAVEMENT" to be as follows:—
.
'My Invention relates to cement or composition specially adapted for use in the
laying down and fixing of blocks or sections of wood' in the formation of floors and
pavement. In ordinary practice the blocks are laid upon a concrete or cement bed
which is finished to have an even level surface. When laying the blocks upon this
surface I employ a tenacious cement which is heated the blocks being dipped into
the hot cement and laid close together. The said cement consists of resinous
matters such as ordinary resin of any quality resinous gums or shellac, grease or
fatty matters chrysyllic acid or other derivative of carbolic acid, heavy anthracene
or other coal tar oils, coal-tar pitch and Stockholm tar. I do not confine myself to
the use of all the said matters in the one preparation. The matters are boiled
together until thoroughly amalgamated and until the composition when cold has a
sticky tenacious nature and a bright appearance. The parts of a flooring laid with
this cement are compactly and firmly held together and to the foundation and the
flooring resists the effects of moisture and "dry rot."

I ROGER LEIGH LOWE of the Britannia Works Worsley Road Farnworth in the
County of Lancaster Contractor do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN CEMENT OR COMPOSITION FOR USE IN THE LAYING OF
'FLOORS AND PAVEMENT 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 cement or composition specially adapted for use in the
laying down and fixing of blocks or sections of wood in the formation of floors and
pavements. In ordinary practice the blocks are laid upon a concrete or cement bed
which is finished to have an even level surface. When laying the blocks upon this
surface I employ a tenacious cement which is heated, the blocks being dipped into
the hot cement and laid close together. The said cement consists of resinous
matters such as ordinary resin of any quality resinous gums or shellac, grease or
fatty matters chryscyllic acid or other derivative of carbolic acid, heavy anthracene
'or other coal-tar oils, coal-tar, pitch and Stockholm tar. The proportions of the
ingredients may be varied to some extent but by way of example I will state
proportions which I have found to give satisfactory results that is to say I take the
following substances in the given proportions namely:
Resinous matters such as ordinary resin or rosin or shellac or other gum resins
four parts.
Mineral grease or fatty matter twelve parts.
Stockholm tar, two parts,
:
Minoral pitch, bitumen, asphaltum or other adhesive pitch, two parts.
Chryscyllic acid or carbolic acid or any of its derivatives one and a half parts.
Theso matters are melted in a suitable pan or boiler and to them are added four
parts of resin, oil, heavy anthacene oil or other oil or oleaginous matter having a
high boiling point. The matters are boiled together until thoroughly amalgamated
and until the composition when cold has a sticky tenacious nature and a bright
appearance. The time during which the boiling has to be continued will vary as
the consistency or nature of the component parts will vary to some extent from
time to time so that some experience is required to enable the operator to determine
when the proper consistency is obtained. In practice I continue the boiling for
about five or six hours on the average but this must not be considered a fixed time.
As ordinary resin is much cheaper than other resinous gums this material is usually
employed but shellac' or a proportion of shellac may be used with advantage when
the price of the same is not prohibitive. It is of great importance that the oils
used should bave a high boiling point and for this reason I use the heavy anthracene
oils or residues from the distillation processes in order that the oil may withstand
the long continued boiling without being volatilised. If suitable oils are not used
a large proportion of the oil is evolved and the cement becomes brittle. The acid
being used principally as a preservative may be left out if not considered to be
necessary. The parts of a flooring laid with this cement are compactly and firmly
held together and to the foundation and the flooring resists the effects of moisture
and "dry-rot."

page_text: 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 cement composed and prepared substantially as and for the use
berein before set forth and indicated.
2. A cement for the purpose set forth consisting of resinous matter or matters,
grease, tar or pitch or both tar and pitch and heavy anthracene oil or other oil
having a higher boiling point than the rest of the composition with or without the
addition of chryscyllic or carbolic acid or derivatives the whole treated by boiling
substantially as set forth and indicated.
