WILLIAM THOMAS HICKS 3 St. Pauls Road Middlesbro Stocktaker JOSEPH
ELLIOTT 315 Newport Road Middlesbro Boiler Maker do hereby declare the nature of
this invention to be as follows:-
Our Invention relates to a combination of Ingredients, for making up a composition
which may be applied to metallic surfaces, as a lubricant, and is especially adapted
where friction is excessive, whether generated from great pressure or great speed, or
where a continuous supply of a lubricating composition must be maintained, which is
at present done by means of a constant attendant as in the case of lubricating the
bearings of rolling mis employed in iron and steel works, or canvas bags are charged
with the lubricating composition and placed in contact with the surfaces, they are
intended to lubricate, with the result that such canvas bags are liable to become heated.
and in some cases to set fire to their contents.
In making up a lubricating composition according to our invention we employ
as ingredients heat absorbing or cooling matter in the shape of "Peat or Turf."
This Peat or Turf we mix with any suitable animal fat. such as the suet or tallow
ordinarily used in the manufacture of lubricating compositions, to which a small
quantity of "black-lead" may be adde l, and in order to make our lubricating com-
position sufficiently adhesive to metallic surfaces even when hot, and at the same time
to flow freely over or between metallic surfaces so as to lubricate them effectively, we
add to the above ingredients, a small quantity of pitch or equivalent material, thus for
instance to a mixture of 6 pounds of Peat or Turf. 4 pounds of pottery clay 5 pounds
of animal fat and 3 ounces of black-lead 4 ounces of pitch may be added.
The tallow or animal fat is boiled down in the usual manner to a molten condition
the black-lead and pitch are then added, and are melted by the heat of the tallow with
which they are thoroughly intermixed. The mixture is then put in moulds and
allowed to ool down to a pasty or plastic condition, with the temperature not above
what can be borne by the naked hand; the peat or Turf is then added and thoroughly
incorporated with the other ingredients. The composition may then be allowed to

page_text: cool, when it is ready for use, but if it has been made up to become hard when cool,
before being allowed to set, it should be formed into lumps, or soparate pieces of the
sizes and shapes in which it is intended to be used.
From the quantity and proportions of the above named ingredients about 12 pounds
of our lubricating composition may be obtained. The proportions herein-before named
form a suitable mixture for an effective lubricant, but the proportion of these
ingredients, may be varied according to the properties intended to be imparted to the
lubricant, thus for instanco the lubricant may be preferred sufficiently hard and firm,
to retain the form of bricks, sluts, or of other configurations convenient for applying
it to metallic surfaces, or in some cases a more pasty condition may be preferred suitable
for charging, the composition into lubricating receptacles, or in cases where the
surfaces, subjected to friction are liable to become very hot the composition should have
sufficient adhesiveness or plasticity imparted to it to resist being reduced like ordinary
lubricant to a mere scouring wash.

page_text: We, WILLIAM THOMAS HICKS and JOSEPH ELLIOTT, both of Middlesbrough-on-
Tees, in the County of York, 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 :-
The object of our invention is the manufacture of a lubricating composition, more
especially intended for lubricating the necks of rolls in rolling mills employed in iron
and steel works, or other bearings subjected to great friction, whether generated from
excessive pressure or high speed, and where a continuous supply of lubricant must be
maintained.
In the case of the bearings of rolling mills the lubricant has heretofore been applied
by a constant attendant, or enclosed in canvas bags, with the result in the latter case
that the bags are liable to become heated and to set fire to their contents.
In the preparation of a lubricating composition according to our invention, we
employ among other ingredients, heat absorbing or cooling material in the shape
of peat or turf, to prevent waste of the lubricant by overheating. This peat or turf
we mix with any suitable animal fat, such as the suct or tallow ordinarily used in
the manufacture of lubricating compositions, and combine therewith other ingredients
as hereinafter described.
For the purpose of lubricating the bearings of rolling mills or other like heavy
machinery, we find the following ingredients and proportions of same to give good
results, viz.peat or turf 14 lbs.; pottery clay 6 lbs.; animal fat, or its equivalent
7 lbs. black lead 3 ozs. ; and gutta percha or Indian rubber 4 ozs. These quantities
when properly prepared will yield about 20 lbs. of lubricating composition.
i
The composition is preferably obtained by the following process. We reduce the
gutta percha or Indian rubber to a molten or liquid state by means of heat, then add
the animal fat, or its equivalent, and blend the two materials well together while in a
boiling state, the pottery clay being added if necessary to protect the tallow or fat
from the effects of the heat. The black lead is then added, the mixture being kept at
the boiling point until all these ingredients are well mixed together. The peat or turf
is now added and thoroughly incorporated with the other materials, and the composition
is then poured into moulds and allowed to cool down when it is ready for use.
We wish it to be understood that the above described process and the proportions of
the ingredients may be modified if desired, provided that the different ingredients
are present in the composition in suitable proportions and that they are thoroughly
incorporated together.
If the composition is to be applied to surfaces liable to become very hot, a sufficient
quantity of gutta percha or Indian rubber must be employed to cause the composition
to set hard, and it must be poured into the moulds before cooling. For surfaces
where less heat is generated a smaller proportion of gutta percha or Indian rubber is
used, and the composition will then cool down to a pasty state, and can be used for
lubrication in the ordinary manner.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
1. A lubricating composition consisting of the combination of peat or turf, animal
fat or its equivalent, gutta percha, or Indian rubber, pottery clay, and black lead, the
said ingredients being present in the composition in the relative proportions, substan-
tially as heroin set forth.
2. In the manufacture of fatty, plastic, or the like lubricating compositions, tho
combination therewith of a heat absorbing or cooling ingredient, such as peat or
turf, substantially in the manner and for the purpose as herein set forth.
