PROVISIONAL SPECIFICATION left by the said Henry Parker Hayhoe at the
Office of the Commissioners of Patents on the 7th February 1878.
HENRY PARKER HAYHOE, of Stowmarket, in the County of Suffolk. "AN
IMPROVED PREPARATION FOR CLEANING PAINT, VARNISH, OR JAPAN, AND FOR
REMOVING PAINT, VARNISH, JAPAN, OR GREASE FROM WOODEN OR OTHER SURFACES,
OR OXIDE OR DIRT FROM THE SURFACE OF METALS."
The present Invention_consists of certain improvements upon an Invention for
which I obtained Letters Patent dated 18th October 1875; No. 3614.
The preparation which forms the subject of the present Invention has for its
object (like the former one) the softening of old paint or varnish preparatory to
removing it from the surface to which it has been applied.
One objection to the former preparation was, that when applied to the surface to
be operated upon it was liable to dry too quickly, and therefore had to be
moistened before the paint could be scraped off the surface. To correct this
objection I dispense with the soft soap formerly employed, and I add to the alkaline
composition a quantity of treacle, which will prevent the preparation from drying
when laid on the painted surface.
The proportion in which the treacle is added to the other ingredients may be
slightly varied, but as an example of the proportions in which the several
ingredients may be usefully employed I will give the following:-Take from 96 to
100 gallons of water, and slack therein 10 pecks of lime so as to produce a milk of
lime, to which is to be added 30 lbs. to 35 lbs. weight of treacle. These ingredients
must be placed in a boiler and well mixed, and then 10 stones of flour (mixed in
D

page_text: from 35 to 40 gallons of water) are to be added thereto, when the whole mass may
be heated to about 200° Fah. I then add 4 cwt. of soda and boil for about 20
minutes. The liquor is then drawn off and strained, and when cool a gallon of
carbolic acid is added.
This compound may be used either for cleaning paint (for which purpose it must
be diluted), or for softening paint, varnish, or japan, preparatory to removing the
same from any wooden or other surface.
SPECIFICATION in. pursuance of the conditions of the Letters Patent filed by
the said Henry Parker Hayhoe in the Great Seal Patent Office on the 7th
August 1878.

HENRY PARKER HAYHOE, of Stowmarket, in the County of Suffolk.
IMPROVED PREPARATION FOR CLEANING PAINT, VARNISH, OR JAPAN, AND FOR
REMOVING PAINT, VARNISH, JAPAN, OR GREASE FROM WOODEN OR OTHER SURfaces,
OR OXIDE OR DIRT FROM THE SURFACE OF METALS."
The present Invention consists of certain improvements upon an. Invention for
which I obtained Letters Patent dated eighteenth October, One thousand eight
hundred and seventy-five.
The preparation which forms the subject of the present Invention has for its
object (like the former one) the softening of old paint or varnish preparatory to
removing it from the surface to which it has been applied.
One objection to the former preparation was, that when applied to the surface to
be operated upon it was liable to dry too quickly, and therefore had to be
moistened before the paint could be scraped off the surface. To correct .this
objection I dispense with the soft soap formerly employed, and I add to the
alkaline composition a quantity of treacle, which will prevent the preparation from
drying when laid on the painted surface.
The proportion in which the treacle is added to the other ingredients may be
slightly varied, but as an example of the proportions in which the several
ingredients may be usefully employed I will give the following:-Place in a
suitable wooden trough about fifteen gallons of water, and add thereto ten pecks of
unslacked lime; let it remain until the lime is well slacked, then add fifteen gallons
more water so as to produce a milk of lime, to which when cool is to be added from
thirty to thirty-five pounds weight of treacle. These ingredients must be well
stirred so as to be become thoroughly mixed, and seventy gallons more of water
added. The liquid may then be drawn off and strained into a copper or boiler.
Ten stones of flour (mixed in from thirty-five to forty gallons of water) are to be
added to the lime water in the copper, when the whole mass must be well stirred
for about half an hour, and then boiled or heated to about two hundred degrees
Fahrenheit for about twenty minutes, gradually adding four and a half hundred
weight of common carbonate of soda, and taking care to keep the mixture con-

page_text: tinually stirred during the boiling. The liquor is then drawn off and strained, and
when cool a gallon of carbolic acid is added for the purpose of preventing the pre-
paration from undergoing decomposition.
This compound may be used either for cleaning paint (for which purpose it must
be diluted), or for softening paint, varnish, or japan, preparatory to removing the
same from any wooden or other surface, and for removing oxide or dirt from the
surface of metals.
.
This improved preparation may be made up for the market in either a liquid,
semi-fluid, or in a solid form, the latter form being obtained by evaporation.
Having now described my Invention of "An Improved Preparation for Cleaning
Paint, Varnish, or Japan, and for Removing Paint, Varnish, or Japan, or Grease
from Wooden or other Surfaces or Oxides or Dirt from the Surfaces of Metals," and
having explained the manner of carrying the same into effect, I would remark
that I make no claim for the admixture of lime, soda, or other caustic alkalies
with water for the purpose of producing a liquid detergent preparation, nor yet for
the addition thereto of flour or paste, except when such substances are used in
combination with the other ingredients herein-before set forth, but that which I
consider to be new in the improved preparation herein-before described, and desire
to claim as the Invention secured to me by Letters Patent as aforesaid is, the
combination with caustic alkalies and water of treacle and carbolic acid, as and for
the purpose herein set forth.
In witness whereof, I, the said Henry Parker Hayhoe, have hereunto set my
hand and seal, the Third day of August, in the year of our Lord One
thousand eight hundred and seventy-eight.
H. P. HAYHOE. (L.S.).
