I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVED MEANS
OF PROTECTING OR SHEATHING CAKES OR CARTRIDGES OF LUBRICATING COMPOUND
"
OR MATERIAL a communication to me from abroad by Dyson Dearbon Wass of
the City County and State of New York, United States of America, to be as
follows:-
This invention relates to the protection of cylinders blocks or cartridges composed
of a lubricating compound such as that specified in another application for Letters
Patent of even date herewith or any other lubricating compound or material and
it consists in sealing or enveloping the blocks or cartridges of lubricating material
or compound in a sheath of paraffine or equivalent unctuous substance or substances
(such for example as waxes that solidify at the ordinary atmospheric temperature
and melt at a low heat) having lubricating properties and capable of protecting
the lubricating compound from the air and on the one hand of bearing handling
and on the other of being melted by the heat developed by the friction of the
journal to which it is applied so that when so melted it well mix with the mass.
and become a constituent of the lubricating compound.
The blocks cylinders or cartridges having been pressed moulded cut up or other-
wise formed into pieces of suitable shape and size for insertion into the grease
boxes of machinery are enveloped in the protective sheathing by dipping them
one or more times into paraffine or other equivalent unctuous material in a melted
condition and quickly withdrawing them whereby they are completely covered
with an external coating which effectually seals up protects and preserves the
blocks of lubricating compound or material, preventing the access of air or moisture,
giving them a smooth and comparatively hard covering which enables them to be
conveniently transported handled and used.

page_text: The blocks cylinders or cartridges thus prepared are simply placed in the grease
box or other receptacle in communication with the journal to be lubricated the
heat developed being sufficient to melt the whole, compound and covering,-
together.
I am aware that a lubricating cartridge is not broadly new and that prior to
the present invention such cartridge has been enclosed in a shell of paper cloth
tin-foil or other similar wrapping substance which it is evident does not possess
the advantage of the sheath of this invention namely of possessing both lubricating
and protective qualities and of being wholly consumed in use.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Palent
Agents, do hereby declare the nature of the said Invention for "IMPROVED MEANS
OF PROTECTING OR SHEATHING CAKES OR CARTRIDGES OF LUBRICATING COMPOUND
"
OR MATERIAL (a communication to me from abroad by Dyson Dearbon Wass of
the City County and State of New York, United States of America,) and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :—
This Invention relates to the protection of balls, cakes, cylinders, blocks, or
cartridges composed of a lubricating compound such as, that specified in another
application for Letters Patent of even date herewith, or any other lubricating
compound or material, and it consists in sealing or enveloping the blocks or
cartridges of lubricating material or compound in a sheath of paraffine or equi-
valent unctuous substance or substances (such for example as waxes that solidify
at the ordinary atmospheric temperature and melt at a low heat) having lubricating
properties and capable of protecting the lubricating compound from the air, and,
on the one hand, of boaring handling, and, on the other, of being melted by the
beat developed by the friction of the journal to which it is applied so that when
so melted it will mix with the mass and become a constituent of the lubricating
compound.
The blocks cylinders or cartridges having been pressed, moulded, cut up, or
otherwise formed into pieces of suitable shape, and size, for insertion into the
grease boxes of machinery, are enveloped in the protective sheathing by dipping
them one or more, times into paraffine or other equivalent unctuous material in a
melted condition and quickly withdrawing them whereby they are completely
covered with an external coating which effectually seals up, protects, and preserves,
the blocks of lubricating compound or material, preventing the access of air or
moisture, giving them a smooth and comparatively hard covering which enables
them to be conveniently transported, handled, and used.

page_text: The cylinders or cartridges may, when finished, conveniently have a diameter of
1 inch a length of 2 inches and a weight of one ounce but any other dimensions
and any desired shape may be adopted.
The blocks, cylinders, or cartridges, thus prepared, are simply placed in the
grease box or other receptacle in communication with the journal to be lubricated
the heat developed being sufficient to melt the whole, compound and covering
together.
I am aware that a lubricating cartridge is not broadly new and that prior to the
present invention such cartridge has been enclosed in a shell of paper cloth tin-foil
or other similar wrapping substance which it is evident does not posses the advan-
tage of the sheath of this invention namely of possessing both lubricating and
protective qualities and of being wholly consumed in use.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
.
1st A ball, cake, or cartridge, of lubricating material or compound enclosed and
sealed within a shell or coating of paraffine or equivalent material as set forth.
2nd The mode of protecting balls, cakes, or cartridges of lubricating compound
or material, by enclosing or scaling the same within a shell or coating of paraffine
or equivalent material applied in the manner set forth.
