A New or Improved Waterproofing Compound or Composition.
I, THOMAS THOMPSON, of 40, Sanvey Gate, Leicester, do hereby declare the nature
of this invention to be as follows:-
This invention has reference to a new or improved compound or composition
applicable for waterproofing leather, boots, shoes and other articles.
The said compound comprises in suitable proportions paraffin wax castor oil or
other vegetable oil resin, animal fat, and acetate of lead.
1 may also use glycerine either in addition to or instead of the vegetable oil.
To prepare the compound, the vegetable oil and the animal fat are placed in a
vessel and subjected to heat.
At or near boiling point the paraffin wax is added and when dissolved the resin and
acetate of lead are introduced and intimately mixed by stirring until boiling point is
again or nearly reached.
The compound is used warm. Articles such as leather may be placed therein to
soak, but in the case of boots and shoes and other made up goods the composition
may be applied thereto over the surface of same by a soft brush.
I do not confine myself to the strict order named in which the ingredients are
introduced as it is obvious that this may be varied without departing from the
invention.

A New or Improved Waterproofing Compound or Composition.
I, THOMAS THOMPSON, of 40, Sanvey Gate, Leicester, Boot and Shoe Manufacturer,
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:-
This invention has reference to a new or improved compound or composition
applicable for waterproofing leather, boots, shoes and other articles.
The essential constituents of my improved compound are paraffin wax, acetate
of lead, and resin and with these there may be combined animal fat or vegetable
oil as hereinafter described.
As a waterproofing composition for boots and shoes, I have found that a somewhat
different combination of ingredients is preferable for use with the uppers than with
the soles or bottoms thereof.

page_text: After considerable experimenting I have discovered that a composition specially
applicable for the uppers of boots and shoes to render them waterproof and at the
same time to preserve the suppleness and pliability of the leather may consist of the
following ingredients in the proportions named.
Paraffin wax
Neatsfoot oil
Acetate of lead
Resin (powdered)
Beef fat
Glycerine
Palm oil
32 ounces.
4 ounces.
3 ounces.
4 ounces.
8 ounces.
8 ounces.
12 ounces.
The above ingredients are formed into a waterproof composition as follows:-
Into a saucepan or steam jacketed vessel I first place the paraffin wax and allow
it to remain until the heat converts it into a liquid condition, I then add thereto the
neatsfoot oil stirring well to thoroughly mix the two ingredients, then the palm oil 1
is introduced and well stirred in and to this there is put in the beef fat previously
melted so as to bring it to a liquid condition.
The whole is then thoroughly and intimately mixed.
Into a second or separate steam jacketed vessel I place the glycerine and heat it
then add the powdered resin and when these bave become well blended the acetate 2
of lead is next introduced and the whole well mixed.
The contents of this second vessel are now emptied into the first named vessel and
the two separate lots or combinations of ingredients are stirred up together for some
time until an intimate mixture and blending is effected.
The composition is then completed and while hot and in a liquid condition may be 2
applied, preferably by means of a brush, to the uppers of a boot or shoe which should
be well and evenly painted therewith.
For waterproofing the bottoms or soles of boots and shoes I employ a composition
consisting of:-

page_text: Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a waterproofing composition the use or employment in combination of acetate
of lead, paraffin wax and resin.
2. A waterproofing composition consisting of a combination of paraffin wax,
acetate of lead, resin and animal fat.
3. A waterproofing composition consisting of a combination of paraffin wax,
palm oil, glycerine, animal fat, acetate of lead, and resin with or without the
addition of neatsfoot oil substantially as described.
4. The improved waterproofing composition consisting of the ingredients herein-
before mentioned in the proportions substantially as described.
5. The process of producing the hereinbefore described waterproofing composition
which consists in heating and mixing the paraffin wax, neatsfoot oil
and
ог
palm oil
and beef or mutton fat in one vessel and the glycerine, resin and acetate of lead
in another and then mixing together the contents of the two vessels substantially
as described.
