page_text: LETTERS PATENT to John Ellis, of Holbeck, Leeds, in the County of York,
Plumber and Painter, and Silvanus David Oakley, of Hunslet, in Leeds, in
'
the same County, Bricklayer, for the Invention of "AN IMPROVED GLASS-

BE MORE READILY LIGHTED."
ealed the 17th July 1877, and dated the 30th April 1877.
PROVISIONAL SPECIFICATION left by the said John Ellis and Silvanus
David Oakley at the Office of the Commissioners of Patents on the 30th
April 1877.
JOHN ELLIS, of Holbeck, Leeds, in the County of York, Plumber and Painter,
and SILVANUS DAVID OAKLEY, of Hunslet, in Leeds, in the same County, Brick-
layer. AN IMPROVED GLASS-CLEANING LIQUID, WHICH IS ALSO APPLICABLE FOR
CAUSING LAMP WICKS TO BE MORE READILY LIGHTED."
"
This Invention relates to the preparation or compounding of an improved liquid
intended for use in cleaning glass, such as that at railway stations or other places,
or in skylights, or any kind of glass, rough or smooth, or greasy lamps of any
description, and it also relates to and comprises the application of such liquid to the
tips of wicks of lamps for causing them to ignite (in any weather) more readily than
at present.
The improved liquid is made or compounded of mineral turpentine and alkanet-
root in the proportions of about half an ounce of the latter to about one gallon of
the former.
The method of applying it for cleaning glass is as follows:-The window, lamp,
or other glass to be cleaned is first well swept from dust or dirt, and is then well
rubbed over with some cotton waste which has previously been dipped in the
liquid, and it is afterwards well rubbed over with a clean or dry piece of cotton
waste, when the glass will be found to be left clean.
The mode of cleaning hitherto in use was by using acetic acid, which is of an
injurious nature to the hands and clothes of the workmen and to the paint on
contiguous bars or sashes, necessitating the use of a large quantity of water to
prevent as much as possible its destructive effect as soon as the glass has been
cleaned by it.

page_text: The use of the improved liquid for this purpose is advantageous in point of non-
destructiveness to surrounding parts, ease and quickness of application, and economy
of cost, as it forms a support to paint, and can be mixed and applied therewith; it
is not of an acid nature, or in the least injurious to the hands or clothes of the
workmen, it can be used without necessitating the after use of water, and it is of
about one tenth the cost of acetic acid.
This improved liquid may be advantageously applied to the wicks of lamps by
dipping a small brush therein and applying it to the wicks to cause them to light
up quickly. For this purpose spirits of turpentine have hitherto been used.
The use of the improved liquid for this purpose is advantageous in point of
utility and of economy of cost, as it is quicker to catch alight, and is of about one-
third the cost of spirits of turpentine.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said John Ellis and Silvanus David Oakley in the Great Seal Patent Office
on the 23rd October 1877. .
JOHN ELLIS, of Holbeck, Leeds, in the County of York, Plumber and Painter,
and SILVANUS DAVID OAKLEY, of Hunslet, in Leeds, in the same County, Brick-
layer. "AN IMPROVED GLASS-CLEANING LIQUID, WHICH IS ALSO APPLICABLE FOR
CAUSING LAMP WICKS TO BE MORE READILY LIGHTED."
This Invention relates to the preparation or compounding of an improved liquid
intended for use in cleaning glass, such as that at railway stations or in other
places, or in skylights, or for cleaning any kind of glass, whether rough or smooth,
or greasy lamps of any description, and it also relates to and comprises the appli-
cation of such liquid to the tips of wicks of lamps for causing them to ignite more
readily than at present and in any weather.
The improved liquid is made or compounded of mineral turpentine and alkanet-
root, in the proportions of about half an ounce of the latter to about one gallon of
the former.
The method of applying it for cleaning glass is as follows:-The window, lamp,
or other glass to be cleaned is first well swept from dust or dirt, and is then well
rubbed over with some cotton waste which has previously been dipped in the
liquid, and it is afterwards well rubbed over with a clean or dry piece of cotton
waste, when the glass will be found to be left clean.
The previous mode of cleaning such glass was by using acetic acid, which greatly
injured or damaged the hands and clothes of the workman and the paint on
contiguous bars or sashes, necessitating the use of a large quantity of water to
prevent as much as possible its destructive effect as soon as the glass has been
cleaned by it.
The use of the improved liquid for this purpose is found very advantageous in
point of non-destructiveness to surrounding parts, in its ease and quickness of appli-
cation, and in its economy of cost, as it forms a support to paint, and can be mixed
and applied therewith; it is not of an acid nature, or in the least injurious to the
hands or clothes of the workman; it can be used without necessitating the after use
of water, and it is of about one-tenth the cost of acetic acid.
This improved liquid may be advantageously applied to the wicks of lamps by
dipping a small brush therein and applying it to the wicks, which will cause them
to light up quickly. For this purpose spirits of turpentine have hitherto been
used.
The use of the improved liquid for this purpose is found advantageous in point
of utility and of economy of cost, as it is quicker to catch alight, and is of about
one-third the cost of spirits of turpentine.
Having now described the nature and object of our said Invention, together with

page_text: the manner in which the same is to be or may be performed or carried into practical
effect, we would remark in conclusion that we claim as our Invention,―
Firstly. The preparation and use of the improved glass-cleaning liquid, sub-
stantially as herein described, for cleaning glass of all kinds and in all places.
And, Secondly. The application and use of such liquid to cause the more ready
ignition of lamp wicks, substantially as herein described.
In witness whereof, we, the said John Ellis and Silvanus David Oakley, have
hereunto set our hands and seals, this Thirteenth day of October, in the ⚫
year of our Lord One thousand eight hundred and seventy-seven.
