IMPROVEMENTS IN THE MANUFACTURE OF MORTAR
Year: 1884

page_text: I MILES WILLIAMS of Beechlee Edge Lane Liverpool and of the Britannia
Varnish Works Millgate Wigan both in the County of Lancaster Varnish Manu-
facturer do hereby declare the nature of my invention for IMPROVEMENTS IN THE
MANUFACTURE OF MORTAR to be as follows:-
I take Scorice, Furnace or other ashes or Cinders, Breeze (coke) sand, slag, dried
or burnt clay, stone, Brick bats or Flue dust or similar substances or mixtures of
them and dry them if necessary and then pulverise disintegrate or grind them into
powder of varying and suitable degrees of fineness and mix them intimately either
before or after grinding with a proportion (varying according to the quality of
materials used and mortar required) of Sanitary Dry Lime as prepared by my
patent No 7255 of the year 1884 or I use Quick lime or Air slacked Lime so as to
produce a dry or comparatively dry mortar in a powder having the particles
thereof perfectly intermixed when finely ground and so producing a mortar of
great strength simply by adding water when required for use. Moreover when a
judicious mixture of the ingredients above named is used the quality of the
mortar can be purposely varied so as to become either air-drying or hydraulic or
plaster or cement according to the purpose for which it is required and either with
or without the admixture of other mortars or cements.

I MILES WILLIAMS of Beechlee Liverpool and of the Britannia Varnish Works
Wigan both in the County of Lancaster Varnish Manufacturer do hereby declare
the nature of my Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
MORTAR" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
I take scoriæ, furnace, or other ashes or cinders, breeze, coke, sand, slag, dried or
burnt clay, stone, brick bats, flue dust or similar substances or mixtures of them and
dry them if necessary and then pulverise disintegrate or grind them into powder of
varying and suitable degrees of fineness and mix therewith intimately either before
or after grinding a proportion (varying according to the quality of materials used
and mortar required) of sanitary Dry Lime as prepared by my patent No 7255 of
the year 1884 or any manner similar or analogous to the same or I uso quick limo
or air slacked lime the object being the production of a dry or comparatively dry
mortar in a powder perfect association of the particles and capable of being quickly
ground and made into Mortar of great strength by simply adding water when
required for use and when prepared by a judicious mixture of the ingredients
named herein can be used both as an air drying or hydraulic mortar plaster
or cement with or without tho admixture of other mortars or cements. The
advantages of this dry mortar are many and important and may be briefly stated.
A superior mortar in a dry or comparatively dry state which can be stored or
packed for portability in bags boxes or other suitable receptacles. Will keep corr
for any length of time and improves with age-Can be prepared at all times and
kept for future use-Easy of conveyance and can be shipped and freighted at
nearly half the cost of ordinary wet mortar-Can be prepared as rapidly and with
the same power as one and a half tons of wet mortar.
The utilization of ashes cinders and incorporate and other bodies which are now
costly to get rid of into a valuable useful and saleable commodity and rendered a
source of profit by this simple and inexpensive method.
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. "Dry Mortar" and the method of preparing the same substantially in the
manner and for the purposes herein before particularly set out and described.
2. Mortar in a dry or comparatively dry state so as only to necessitate the
addition of water when required for use.
3. Mortar so prepared that the proportions of lime and other ingredients can be
varied whilst dry so as to answer best air drying or hydraulic mortar as may be
required.
4. Mortar that can be stored in bags or other receptacles and carried shipped or
stored without deterioration.
