PROVISIONAL SPECIFICATION.
Improvements in or connected with Disinfectants.
We, PATRICK MOLYNEUX of 30 Bruce Road, Bow, in the County of Middlesex,
Oil Refiner, and GABRIEL RAWLINGS POTTS, of Waverley Chambers, South
Shields, in the County of Durham, Auctioneer, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in or connected with disinfectants by which
certain advantages are obtained.
In order that the nature of our invention may be readily and sufficiently under-
stood we shall proceed to describe, mainly, by way of a type or example one way
by which we may carry our invention into effect and manufacture disinfectants,
existing in the form of a liquid, a paste and a powder, of great efficiency.
We take black sea oil and creosote in proportions of one half pint of black sea
oil and one pint of creosote of a specific gravity of from 790 to 800. These
ingredients we thoroughly mix in a pan or other suitable vessel and raise the
mixture to a temperature of about 180° Fahrenheit, and blend or mix with the
above named ingredients an equal weight or thereabouts of a solution of caustic
soda, of about 25 gravity (Twaddle's hydrometer). After thoroughly mixing
the three above ingredients in about the proportions described above, we allow the
whole to cool and stand for about one week.
For the sake of convenience of description we shall hereafter refer to this
compound as compound A.
We then take resin and a solution of caustic soda, in proportions of about
one pound of resin to about every half pint of solution of caustic soda, or thereabouts,
of 20 gravity (Twaddle's hydrometer), or thereabouts, and mix and stir them
thoroughly at a temperature sufficiently high (about 160 degrees Fahrenheit) to
dissolve the resin. We now add creosote of a specific gravity of 790 to 800 and in
bulk equal to the combined ingredients last named, and thoroughly mix by stirring
or agitating, and bring the mass to a temperature of 190 to 200 degrees Fahrenheit,
or thereabouts.
For the sake of convenience of description we shall hereafter refer to this
compound as the compound B.
We now mix the compounds A and B in the proportion of about one third part
of the compound A to about one part of the compound B and agitate the mass
until it becomes frothy, after which we allow it to cool down to a temperature of
about 120 degrees Fahrenheit.
We now add to every ton of the combined compounds A and B a mixture of
about five pounds of the substance known as albo-carbon, dissolved in about
one gallon of creosote of 790 to 800 gravity or thereabouts.
The mass so formed we now thoroughly mix and allow to cool and settle.
After cooling a sediment is deposited at the bottom of the vessel in which the
mixture has been made or allowed to cool; from this sediment we draw off the
liquid for use as a liquid disinfectant.
We now mix with the sediment new lime, freshly slaked, in the proportion of
about one gallon of sediment to every fourteen pounds, or thereabouts, of new lime
which has been slaked.
After a thorough turning over with shovels or by other means, we allow the
mass to cool and stand for about twelve hours, when it is ground in a mill to a
powder, for use as a disinfecting powder.
When it is desired to prepare our disinfectant in the form of a paste, we leave

page_text: sufficient of the liquid with the sediment to form a pasty mass, which may if desired
be pressed into blocks in moulds.

Improvements in or connected with Disinfectants.
We, PATRICK MOLYNEUX, of 30 Bruce Road, Bow, in the County of Middlesex,
Oil Refiner, and GABRIEL RAWLINGS POTTS, of Waverley Chambers, South
Shields, in the County of Durham, Auctioneer, 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:-
Our invention relates to improvements in or connected with disinfectants by
which certain advantages are obtained.
In order that the nature of our invention may be readily understood, we shall
proceed to describe mainly by way of a type or example one way by which we
may carry our invention into effect and manufacture disinfectants existing in the
form of a liquid a paste or a powder of great efficiency.
Our improvements consist in the manufacture of disinfectants substantially in
the manner and in the proportions hereinafter set forth.
We take petroleum, preferably that known as black sea oil, and creosote in
proportions of one half pint of black sea oil and a pint of creosote of a specific
gravity of from 790 to 800. These ingredients we thoroughly mix in a pan or
other suitable vessel and then raise the temperature of the mixture to about
180 degrees Fahrenheit. Next we mix with the above described compound an
equal weight or thereabouts of a solution of caustic soda of about 25 gravity
(Twaddle's hydrometer). After thoroughly mixing the three above ingredients in
about the proportions above mentioned, we allow the whole to cool and stand for
about one week.
For the sake of convenience of description we shall hereinafter refer to the
above specified compound as compound A.
Proceeding with the manufacture we then take resin and a solution of caustic
soda in proportions of about one pound of resin to about every half pint of solution
of caustic soda of 20 gravity (Twaddle's hydrometer) or thereabouts and stir and
incorporate them thoroughly at a temperature sufficiently high (say about
160 degrees Fahrenheit) to dissolve the resin. We then add creosote of a
specific gravity of 790 to 800, and in bulk equal to the combined ingredients last
named, and thoroughly mix by stirring or agitating and bring the mass to a
temperature of 190 to 200 degrees Fahrenheit or thereabouts.
For the sake of convenience of description we shall hereafter refer to this second
described compound as the compound B.
In proceeding, we next mix the compounds A and B in the proportion of about
one third part by bulk of the compound A to about one part by bulk of the
compound B and agitate the mass until it becomes frothy, after which we allow
it to cool down to a temperature of about 120 degrees Fahrenheit. Then we add
to every ton of the combined compounds A and B a mixture of about five pounds
of the substance commercially known as albo-carbon (naphthaline) dissolved in
about one gallon of creosote of 790 to 800 gravity or thereabouts.
Finally the mass so formed we thoroughly mix and allow to cool and settle.

page_text: After cooling, a sediment is deposited at the bottom of the vessel in which the
mixture has been made and or allowed to cool, and the effluent from this
sediment constitutes a liquid disinfectant.
We now mix with the residual sediment new lime freshly slaked in the
proportion of about one gallon of sediment to every fourteen pounds or thereabouts
of the new lime.
After a thorough turning over with shovels or by other means we allow the
mass to copl and stand for about twelve hours, when it is ground in a mill to
powder and constitutes a disinfecting powder.
When it is desired to prepare our disinfectant in the form of a paste, we leave
sufficient liquid with the sediment to form a pasty mass which if desired may be
pressed into blocks in moulds for subsequent use. We do not confine ourselves to
the above proportious of the several ingredients or temperatures as these may be
varied somewhat without departing from the nature of our invention, but those we
have set forth are found to give good results.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:
1. The herein described manufacture constituting a disinfectant either in the
form of a liquid or a paste, consisting of black sea oil, creosote, caustic soda, resin,
and the substance commercially known as albo-carbon, mixed in the proportions
substantially as above described.
2. The herein above described manufacture constituting a disinfectant in
the form of a powder, consisting of black sea oil, creosote, caustic soda, resin,
and the substance known as albo-carbon and fresh slaked lime mixed substantially
in the proportions specified and then ground as above described.
