IMPROVEMENTS IN LUBRICATORS
Year: 1874

page_text: LETTERS PATENT to Bernhard Kaposi, of No. 9, Sparsholt Road,
Crouch Hill, in the County of Middlesex, for the Invention of
"IMPROVEMENTS IN LUBRICATORS."-A communication from abroad by
Melchior Klosak, of Vienna, in the Austrian Empire.
PROVISIONAL SPECIFICATION left by the said Bernhard Kaposi at the
Office of the Commissioners of Patents, with his Petition, on the
30th September 1874.
I, BERNHARD KAPOSI, of No. 9, Sparsholt Road, Crouch Hill, in the
County of Middlesex, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN LUBRICATORS," to be as follows:
This Invention relates to lubricators for oiling revolving shafts and
other moving or sliding parts of machinery.
The improved lubricator consists of an oil cup or vessel of any
required form or dimensions to suit the part of the machinery to which
it is applied. It is made preferably of tin plate, or of thin brass or

page_text: copper tinned inside to prevent the corrosion of the metal, and the
deterioration of the contained oil. From the bottom of this vessel a
nozzle projects into the oil hole in the usual way. Within the vessel a
perforated tube tapering to a larger diameter upwards is inserted into
the aperture of the nozzle pipe, such tube extending upwards nearly the
whole height of the lubricator. In this tube near its lower end is placed
a plug of cotton or other fibre, through which the oil flowing through
the side perforations of the tube has to soak on its way to the nozzle.
The fibrous plug can be put in loosely or rammed in more tightly
according as a greater or less flow of oil is required, such flow taking
place only while the part lubricated is in motion.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Bernhard Kaposi in the Great Seal Patent Office
on the 25th March 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BERNHARD
KAPOSI, of No. 9, Sparsholt Road, Crouch Hill, in the County of Middle-
sex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirtieth day of September, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
eighth year of Her reign, did, fọr Herself, Her heirs and successors,
give and grant unto me, the said Bernhard Kaposi, Her special license
that I, the said Bernhard Kaposi, my exccutors, administrators, and
assigns, or such others as I, the said Bernhard Kaposi, 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 "IMPROVEMENTS
IN LUBRICATORS," a communication to me from abroad by Melchior
Klosak, of Vienna, in the Austrian Empire, upon the condition (amongst
others) that I, the said Bernhard Kaposi, my executors or admini-
strators, by an instrument in writing under my, or their, or one of
their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be

page_text: 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 Bernhard Kaposi, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the accom-
panying Sheet of Drawings, and to the figures and letters marked
thereon, that is to say :-
This Invention relates to lubricators for oiling revolving shafts and
other moving or sliding parts of machinery..
The improved lubricator consists of an oil cup or vessel of any
required form or dimensions to suit the part of the machinery to which
it is applied. It is made preferably of tin plate or of thin brass or
copper tinned inside to prevent the corrosion of the metal and the
deterioration of the contained oil. From the bottom of this vessel a
nozzle projects into the oil hole in the usual way. Within the vessel a
perforated tube tapering to a larger diameter upwards is inserted into
the aperture of the nozzle pipe, such tube extending upwards nearly the
whole height of the lubricator. In this tube near its lower end is placed
a plug of cotton or other fibre through which the oil flowing through the
side perforations of the tube has to soak on its way to the nozzle. The
fibrous plug can be put in loosely or rammed in more tightly according
as a greater or less flow of oil is required, such flow taking place only
while the part lubricated is in motion.
Figs. 1, 2, and 3, represent vertical sections of several forms of the
lubricator constructed according to this Invention. In these Figures the
same letters are employed to indicate like parts. The case or oil cup A
may be of glass or earthenware as in Fig. 1, or tin plate, brass, or other
metal as in Figs 2 and 3, being preferably tinned inside when the metal
is of an oxidisable kind. Within the cup is a taper tube B inserted into
the nozzle where it may be fixed by solder or otherwise. This taper
tube has several holes bored or punched through its sides, and has inside
a plug C of cotton, wool, felt, or other fibrous material, or it may be
sponge or other porous material. A twisted wire or a hook D enwrapped

page_text: by or holding the plug C extends upwards within reach of the fingers,
so that by pulling it up or pressing it down the plug may be slackened
or tightened within the taper tube, according as a greater or less flow of
oil is desired. It is obvious that the wire or hook D might be moved by
a screw or rack and pinion like the wick of a lamp.
i
Having thus described the nature of this Invention and in what
manner the same is to be performed, as communicated to me by my
foreign correspondent, I claim, the use in a lubricator of an internal
tapering perforated tube provided with a fibrous or porous plug, by the
tightening or slacking of which the flow of oil can be regulated, sub-
stantially as herein described.
In witness whereof, I, the said Bernhard Kaposi, have hereunto set
my hand and seal, this Twenty-fifth day of March, in the year of
our Lord One thousand eight hundred and seventy-five.
