page_text: MURDOCH MACKAY 1 Ruby Street, Old Kent Road, in the County of Surrey,
Manufacturing Chemist, do hereby declare the nature of this invention to be as
follows:-
My Invention has for its object the combination of materials to form an improved
composition for fusible cements which may be used in place of Cements made from
materials used under that name in architecture, as well as those employed by the
Jeweller the Mason and other persons in their respective callings, and also as a sub-
stitute for metals for castings, and for other useful and ornamental purposes, it is not
affected by water, acids or alkalies it is a good and economical Electrical Insulator
stands great pressure is of a hard tough nature difficult to break and can be manu-
factured at a low cost. In carrying out my Invention in practice I combine by heat,
in a suitable vessel, (Iron or Copper preferred). Three parts Sulphur one part
powdered silicate of magnesia steatite preferred, and two parts powdered fibrous
asbestos, or I may in place of steatite substitute any suitable proportions of aluminic
silicates, or aluminic oxides, but the fibrous asbestos must not be omitted as it gives
strength solidity and toughness to the composition. The proportions may be varied
according to the hardness and metallic lustre required. I may also combine any
suitable coloring matter or pigments with the cements. If I wish to make a softer
and more adhesive composition, I leave out a portion of the Sulphur and replace it
by Tar, Rosin or other suitable resinous or oleaginous matter which gives the cement
more adhesive properties when applied to the joints of pipes and Tanks, and which
allows for contraction and expansion of the metals.

An Improved Composition for Fusible Cements.

what manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—

in a suitable vessel (iron or copper preferred). Three parts sulphur; one part powdered
silicate of magnesia, steatite preferred, and two parts powdered fibrous asbestos
or I may in place of steatite substitute any suitable proportions of powdered
aluminic silicates; aluminic oxides, or slag; but the fibrous asbestos must not be
omitted as it gives strength solidity and toughness to the composition. The pro-
portions may be varied according to the hardness and metallic lustre required. I may
also combine any suitable coloring matter or pigments with the cements. If I wish
to make a softer or more adhesive composition I may leave out a portion of the
sulphur and replace it by pitch, Tar, rosin, or other suitable resinous, or oleaginous
matter, which gives the cement more adhesive properties when applied to the joints of
pipes or tanks, or coating iron pipes inside or out; and which allows for contraction
and expansion of the metals, or I may reduce the cement to a paint, by adding to it
a hot solution composed of turpentine 9 parts one sixth part of rosin, and one eighth
part of sulphur all by weight, which can then be applied hot or cold with a brush.
I wish it to be understood that I do not confine myself to the exact proportions as
specified, as they may be varied if found necessary.
Having now particularly described and ascertained the nature of my invention, and
in what manner the same is to be performed, I declare that what I claim is :-
I. The combination of materials hitherto defined and set forth to be used as an
improved composition for fusible cements, the composition being novel and useful.
II. The manufacture and use of the improved composition for fusible cements
herein mentioned substantially as described.
