AN IMPROVED APPARATUS FOR LUBRI- CATING THE FRICTIONAL SURPACES OF MACHINERY
Year: 1861

page_text: LETTERS PATENT to Robert Kunstmann, of Manchester, in the County of
Lancaster, for the Invention of "AN IMPROVED APPARATUS FOR LUBRI-
CATING THE FRICTIONAL SURPACES OF MACHINERY."
Sealed the 26th July 1861, and dated the 1st February 1861.
PROVISIONAL SPECIFICATION left by the said Robert Kunstmann at
the Office of the Commissioners of Patents, with his Petition, on the
1st February 1861.
I, ROBERT KUNSTMANN, of Manchester, in the County of Lancaster, Engi-
neer, do hereby declare the nature of the said Invention for "AN IMPROVED
APPARATUS POR LUBRICATING THE FRICTIONAL SURFACES OF MACHINERY," to be as
follows:-
My improved apparatus for lubricating the bearings of shafts and other
frictional surfaces consists in a vessel or chamber for containing the lubricant
furnished with a small interior tube projecting through such vessel in the
direction of the surface to be lubricated. Within this tube is placed a filamen-
tous conductor-or wick, one end being immersed in the oil or other lubricant in
the vessel, and the other end projecting from the lower extremities of the tube,
so that by capillary attraction the lubricant is conveyed from the vessel to the
projecting end of the wick which supplies the surface or bearing requiring
lubrication.

page_text: The improvement further consists in the regulation of the supply of the
lubricant, which is effected by the compression of the said capillary conductor
or wick by introducing extra or compressing wicks into the same tube of
about its own length, so that the flow of the lubricating material may be
hastened or retarded according to the density or compression of the conductor
or wick, and regulated by the addition or removal of a certain number
of fibres of the compressing wick, according to the amount of lubricant
required to be emitted and supplied within a certain time.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Robert Kunstmann in the Great Seal Patent Office on the
27th July 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
KUNSTMANN, of Manchester, in the County of Lancaster, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of February, in the year of our Lord One
thousand eight hundred and sixty-one, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the
said Robert Kunstmann, IIer special licence that I, the said Robert Kunst-
mann, my executors, administrators, and assigns, or such others as I, the
said Robert Kunstmann, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention:
for "AN IMPROVED APPARATUS FOR LUBRICATING THE FRICTIONAL SURFACES OF
MACHINERY," upon the condition, amongst others, that I, the said Robert
Kunstmann, by an instrument in writing under my hand and seal should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Robert Kunstmann, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings (that is to say):-

page_text: My improved apparatus for lubricating the bearings of shafts and other
frictional surfaces is exhibited in Figs. 1 and 2 in the accompanying Drawings,
which are respectively an elevation and sectional view of the lubricator, which
consists in a vessel or chamber a for containing the lubricant b, furnished with
a small interior tube c projecting through such vessel in the direction of the
surface to be lubricated. Within this tube is placed a filamentous conductor
or wick d, one end being immersed in the oil or other lubricant in the vessel,
and the other end projecting from the lower extremity of the tube so that by
capillary attraction the lubricant is conveyed from the vessel to the projecting
end of the wick, which supplies the surface or bearing requiring lubrication.
The improvement further consists in the regulation of the supply of the
lubricant, which is effected by the compression of the said capillary conductor
or wick by introducing extra or compressing wicks e into the same tube, of
about its own length, so that the flow of the lubricating material may be
hastened or retarded according to the density or compression of the conductor
or wick, and regulated by the addition or removal of a certain number of the
fibres of the compressing wick according to the amount required to be emitted
and supplied within a certain time.
In witness whereof, I, the said Robert Kunstmann, have hereunto set
my hand and seal, this Twenty-sixth day of July, in the year of our
Lord One thousand eight hundred and sixty-one.
ROBERT KUNSTMANN. (LS.)
