"AN
JOHN JEYES, of Plaistow, in the County of Essex, Analytical Chemist.
IMPROVED COMPOUND FOR PAVING, BUILDING, AND SIMILAR PURPOSES."
This Invention relates to an improved compound designed to be used for paving
roadways, side walks, and other places, also as a cement for building and similar
purposes, and as a coating or covering for the surfaces of iron, wood, and other
material, a great advantage of the said Invention being, that the said compound
does not require to be heated either in its preparation or when applied to any of
the purposes for which it is designed.
In carrying the said Invention into practice, I reduce to powder by any suitable
means pitch, gum, resin or any similar material that is capable of being dissolved
or partly dissolved by means of a suitable solvent, and I may mix with the
powdered pitch, gum, resin, or other material, or any two or more of these materials
combined, any earthy or sandy particles, which may be reduced to powder or
nearly so, that is to say, the particles may be coarse or fine, and I prefer the
proportions of earthy particles and pitch or the like to be about equal.
When the compound above described (or the gum, pitch, resin or like material
without the above named earthy or sandy particles) is to be used, I add to it slate
or other earthy matter reduced to powder or coarser particles, and which has been
inoistened with any suitable solvent, such as naptha, petroleum spirit, shale spirit,
methylated spirit, turpentine, heavy oil or light oil. The earthy matter and
the solvent will be thoroughly mixed by means of edge runners or other suitable
devices.
The proportions I prefer to adopt are three:-Four or five parts of the moistened
earthy matter to one part of the first-named mixture when the mixture is used.
When the pitch, gum, resin, or similar materials are mixed with the moistened
earthy matters without previous admixture with earthy particles, the proportion of
pitch or like material is reduced pro rata. The whole is well mixed together by
sifting or any other suitable process, so that the particles may be thoroughly
incorporated with each other, and this mixture forms a cohesive compound after

page_text: being pressed or beaten, and becomes hard and impervious to moisture, and is thus
very advantageous for use in all cases in which asphalt, concrete or the like is used,
no heating being required.
The principle of my invention may also be carried into effect by using a solution
of gum, resin, pitch or the like, and mixing the said solution with a suitable
proportion of earthy matter.
When it is desired to use the said compound as a protective coating or covering
for iron, wood, stone, brickwork, concrete, or other surfaces required to be kept
water or damp proof, or to resist the effects of heat and cold, I bring the said
compound into a plastic condition by means of spirit or any light or volatile solvent.
This plastic compound may also be used as mortar is used for uniting bricks,
stones or other objects, or articles employed in building operations.
The said compound when in a plastic state will be found very advantageous for
covering and protecting the inner surfaces of ships, barges, boats, tanks and other
structure.
The proportions herein stated are those I prefer to use, but I wish it understood
that these may be somewhat varied according to the particular uses to which the
compound is to be applied.
