Year: 1863

page_text: LETTERS PATENT to Robert Lavender, of No. 332, Goswell Road, in
the Parish of St. Mary, Islington, in the County of Middlesex, Ink
Manufacturer, for the Invention of "A NEW COMPOUND TO BE USED AS A
LUBRICATOR."
COMPLETE SPECIFICATION filed by the said Robert Lavender at the
Office of the Commissioners of Patents, with his Petition and Declara-
tion, on the 24th April 1863, pursuant to the 9th Section of the Patent
Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
LAVENDER, of No. 332, Goswell Road, in the Parish of St. Mary, Islington,
in the County of Middlesex, Ink Manufacturer, send greeting.
WHEREAS I am in possession of an Invention for "A NEW COMPOUND
TO BE USED AS A LUBRICATOR," and have petitioned Her Majesty to grant unto
me, my executors, administrators, and assigns, Her Royal Letters Patent
for the same, and have made solemn declaration that I am the true and first
Inventor thereof:-
NOW KNOW YE, that I, the said Robert Lavender, do hereby declare
that the following Complete Specification under my hand and seal fully de-
scribes and ascertains the nature of the said Invention, and in what manner
the same is to be performed, in and by the following statement thereof,
(that is to say):—
My Invention consists in combining together certain well known materials
in such proportions as may best suit the especial use for which it is intended,

page_text: to form when compounded a new and useful lubricator to be used in all kinds
of journals or bearings of machinery, or as a substitute for grease in covering
machinery, to prevent oxydation.
The formula I prefer for the new compound is as follows:-I use as a sub-
stitute for railway grease or journals of steam boat shafts or any large or small
bearings, ten parts of the hydro-carbonaceous material known as paraffin
oil of any density best suited for the especial compound, I then add to it one
and a half parts of common rosin or any of the resinous gums that are soluble
in the above material. These two are mixed together by heat or otherwise,
and after being properly united I take lime water up to the point of satura-
tion, or any of the alkilies, which will cause sapponification, and add it to the
above compound by stirring or agitating in such a manner so as to bring it
into contact with the alkaline properties to sappomify to any degree I may deem
necessary the before mentioned mixture. These materials when chemically
united form an unctious compound well suited for all purposes of lubrication.
I do not confine myself to that material known as paraffin oil obtained from
the oil wells of America or elsewhere, but I use a material similar with it,
(viz.,) the mineral oils obtained from the distillation of coal or the products of
coal, or from peat, bitumen, and other substances, which oil can be used in the
same manner as before described.
Having thus fully described the nature and particulars of iny said Invention,
and the manner of compounding such materials together, I desire it to be
distinctly understood that I do not confine myself to the exact details herein
set forth, as they may be varied or modified in any degree without departing
from the principle of such chemical union formed of the ingredients herein
named, but I claim the compounding together of paraffin oil or any of the
mineral oils from the distillation of coal or bituminous matter or of any
material yielding this oil with any of the resinous gums that are soluble in
such oils, and saponify then with lime water or any suitable alkali for the
purposes of compounding a lubricating material as fully set forth in this
Specification.
In witness whereof, I, the said Robert Lavender, have hereunto set my
hand and seal, this Twenty-fourth day of April, in the year of
our Lord One thousand eight hundred and sixty-three.
ROBERT LAVENDER. (L.8.)
