We JOSEPH HENRY SPENCER and ALFRED EADEN both of Catherine Street Aston
near Birmingham in the County of Warwick Manufacturers and Copartners do
hereby declare the nature of the said Invention for "A NEW OR IMPROVED
"
LUBRICATOR FOR LUBRICATING THE NECKS OF ROLLS USED FOR ROLLING SHEET
IRON AND STEEL AND OTHER METALS OR ALLOYS AND FOR OTHER LIKE PURPOSES
to be as follows:-
Our invention consists of the new or improved lubricator herein after described
which lubricator is especially useful for lubricating the necks of rolls employed for
rolling sheet iron and steel or for other purposes where the rolls become heated and
for lubricating other rotating bodies.
Our new or improved lubricator consists of a block preferably having the general
figure of an ordinary brick the said block being made of the greasy material called
"dubbin" or hard anti-friction grease or stearine pitch. We use these materials
or any mixture of them or a mixture of essentially the same composition either
with vegetable or animal fibre or without fibrous material. The blocks are formed
by melting the greasy materials enumerated and pouring the liquid into properly
shaped moulds so as to form on cooling blocks of the required form. When we
employ fibrous material we add it to the greasy material when in a state of fusion
and thoroughly incorporate it by stirring. The mould in which the blocks are cast
contains a series of pegs or rods perpendicular to the broader faces of the block.
These pegs or rods are arranged in rows and we prefer to dispose the said rows.
in lines making an angle with the sides of the mould so that no section of the
mould can be made parallel to its ends or sides without passing through a greater
or less number of the pegs or rods. By the use of moulds of the kind described the
blocks produced have in them a series of holes situated in lines making an angle
with the sides and ends of the block. We do not however limit ourselves to the
arranging of the holes in the manner described. The said holes may either be
cylindrical or angular in figure.

page_text: The material of the block is itself a good lubricant but when used with the
necks of rolls or for lubricating other rotating bodies which are heated the oil
which is commonly employed in such cases is used in conjunction with the said
block the holes in the block retaining the oil to such an extent as to prevent
waste. The block in use wears away slowly and at the same time slowly yields
or conducts oil to the rubbing surfaces. The great loss of oil which occurs in the
usual way of applying it to the necks of heated rolls is thereby prevented.
Although our new or improved lubricator is especially applicable to the lubri-
cation of rolls and other bodies which are or become heated it is also applicable to
the lubrication of bodies which are not or do not become much heated.

We JOSEPH HENRY SPENCER and ALFRED EADEN both of Catherine Street,
Aston near Birmingham in the County of Warwick, Manufacturers and Co-partners
do hereby declare the nature of our Invention for "A NEW OR IMPROVED LUBRI-
CATOR FOR LUBRICATING THE NECKS OF ROLLS USED FOR ROLLING SHEET IRON

and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:―
Our invention consists of the new or improved lubricator herein after described
which lubricator is especially useful for lubricating the necks of rolls employed for
rolling sheet iron and steel or for other purposes where the rolls become heated and
for lubricating other rotating bodies.
These
Our new or improved lubricator consists of a block preferably having the general
figure of an ordinary brick, the said block being made of the greasy material called
"dubbin" or hard anti-friction grease, or stearine pitch. We use these materials
or any mixture of them or a mixture of essentially the same composition either
with vegetable or animal fibre or without fibrous material. The animal fibre
which we prefer to use is hair and the vegetable fibre is hemp or flax.
fibres we have found to answer well in practice but we do not limit ourselves to
the use of any particular fibres. The blocks are formed by melting the greasy
materials enumerated and pouring the liquid into properly shaped moulds so as to
form on cooling blocks of the required form. When we employ fibrous material
we add it to the greasy material when the latter is in a state of fusion and
thoroughly incorporate it by stirring. The addition of fibrous material with the
lubricant gives great cohesion to it and prevents its waste when used with the
necks of rolls employed for rolling heated metals and for lubricating other heated
rotating bodies,
The mould in which the blocks are cast contains a series of pegs or rods perpen-
dicular to the broader faces of the block. These pegs or rods are arranged in rows
and we prefer to dispose the said rows in lines making an angle with the sides
of the mould so that no section of the mould can be made parallel to its ends or
sides without passing through a greater or less number of the pegs or rods. By
the use of moulds of the kind described the blocks produced have in them a series
of holes situated in lines making an angle with the sides and ends of the block.
We do not however limit ourselves to the arranging of the holes in the manner
described.
The material of the block is itself a good lubricant but when used with the
necks of rolls or for lubricating other rotating bodies, which are heated, the oil
which is commonly employed in such cases is used in conjunction with the said
block the holes in the block retaining the oil to such an extent as to prevent
waste. The block in use wears away slowly and at the same time slowly yields or

page_text: conducts oil to the rubbing surfaces. The great loss of oil which occurs in the
usual way of applying it to the necks of heated rolls is thereby prevented.
Figure 1 of the accompanying Drawing represents in plan and Figure 2 in
longitudinal section a lubricator made according to our invention, the said lubri-
cator consisting of a block of grease a made of the materials herein before described
the melted grease being poured into a mould having cylindrical pegs which leave
in the cast block, rows of perforations or holes 6 passing from side to side arranged
in the manner represented, that is, the rows of holes are arranged in lines making
an angle with the sides and ends of the block. Other arrangements of the rows of
perforations or holes may be employed and the holes instead of being cylindrical as
represented may be made of an angular figure. The pegs employed in the mould
may either be of the same diameter throughout or taper from one end to the other.
In the latter case the cast block leaves the mould more readily than when the
pegs have the same thickness throughout.
The holes or perforations b in the block or lubricator are filled with the oil used
in conjunction with the block for lubricating the necks of rolls or other rotating
bodies, the said 'holes constituting a series of oil retainers, which holes or retainers
deliver or conduct the oil to the rubbing surfaces at the same time that the block
itself is lubricating the rubbing surfaces.
Although our new or improved lubricator is especially applicable to the lubri-
cation of rolls and other bodies which are or become heated it is also applicable to
the lubrication of bodies which are not or do not become much heated.
Having now particularly .described and ascertained the nature of our inven
tion and the manner in which the same is to be performed we declare that we
claim as our invention
First. A new or improved lubricator for lubricating the necks of rolls and for
other purposes consisting of a perforated block made of the greasy material or
materials or mixture of materials herein before described, or a mixture of essentially
the same composition as that described, the perforations in the said block consti-
tuting oil retainers for retaining and slowly delivering the oil used with the said
block to the rubbing surfaces, the perforations in the block being by preference
arranged in the manner described and represented in the accompanying Drawing.
Secondly. Making the perforated lubricating block of the greasy material or
materials or mixture of materials described mixed with vegetable or animal fibre
as before described.
