PROVISIONAL SPECIFICATION left by the said William Edward
Rumsey and John Laurence Davies at the Office of the Com-
missioners of Patents, with their Petition, on the 13th June 1874.
We, WILLIAM EDWARD RUMSEY and JOHN LAURENCE DAVIES, both
of Liverpool, in the County of Lancaster, do hereby declare the nature
of the said Invention for "AN IMPROVED LUBRICATOR," to be as follows:-
This Invention relates to an improved lubricator specially adapted for
using tallow and other like fatty matters as a lubricant, and consists of
a cup of metal or other suitable material through which passes a tube
or pipe, which tube or pipe is perforated or pierced with suitable sized
holes, according to the density of the lubricant used. Through the tube
and fitting loosely therein there passes a rod or spindle provided at its

page_text: upper end with a weight. The lubricator is fitted with a suitable cover
for filling.
In application the before-mentioned tube is screwed into the bearing
of the shaft or pin requiring lubrication, the rod or spindle projecting
through the tube and resting on the moving shaft or pin. The vibration
of the shaft or pin causes the rod or spindle to work up and down in the
tube and to draw the lubricant to the required point. The rod also
conducts the heat from the moving shaft or pin, and sufficiently melts
the tallow or other like fatty matter as to allow it to run through the
perforations and through the tube before mentioned to the bearing and
shaft or pin requiring lubrication.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edward Rumsay and John Laurence
Davies in the Great Seal Patent Office on the 11th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
EDWARD RUMSEY and JOHN LAURENCE DAVIES, both of Liverpool, in
the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of Junc, in the year of our Lord
One thousand eight hundred and seventy-four, in the thirty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said William Edward Rumsey and John Laurence Davies,
Her special licence that we, the said William Edward Rumsey and John
Laurence Davics, our executors, administrators, and assigns, or such
others as we, the said William Edward Rumsey and John Laurence
Davies, our 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,
ise, exercise, and vend, within the United Kingdom of Great Britain.
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"AN IMPROVED LUBRICATOR," upon the condition (amongst others) that
wc, the said William Edward Rumsey and John Laurence Davies, our
executors or administrators, by an instrument in writing under our or
.

page_text: 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 performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said William Edward Rumsey and
John Laurence Davies, do hereby declare the nature of our said Inven-
tion, and in what manner the same is to be performed, to be parti-
cularly described and ascertained in and by the following statement :-
This Invention relates to an improved lubricator especially adapted for
using tallow and other like fatty matters as a lubricant, and consists of
a cup of metal or other suitable material through which passes a tube
or pipe, which tube or pipe is perforated or pierced with suitable sized
holes, according to the density of the lubricant used. Through the tube
and fitting loosely therein there passes a rod or spindle provided at its
upper end with a weight. The lubricator is fitted with a suitable cover
for filling.
In application the before mentioned tube is screwed into the bearing
of the shaft or pin requiring lubrication, the rod or spindle projecting
through the tube and resting on the moving shaft or pin. The vibration
of the shaft or pin causes the rod or spindle to work up and down in the
tube and to draw the lubricant to the required point. The rod also
conducts the heat from the moving shaft or pin, and sufficiently melts
the tallow or other like fatty matter as to allow it to run through the
perforations and through the tube before mentioned to the bearing and
shaft or pin requiring lubrication.
The beforegoing being the nature, object, and purposes of this our.
Invention, we will now proceed to describe more in detail how the same
may be put into practical effect, and for that purpose we have hereunto
attached a Drawing explanatory of our Invention. Like letters on the
different views denote like parts.
Figure 1 is a sectional elevation of a lubricator constructed according
to our Invention, Figure 2 is a sectional plan of same.
Upon reference it will be seen that a lubricator constructed according
to our Invention consists of a cup a of brass or other suitable material.
Through this cup there passes a tube or pipe b, which tube or pipe is

page_text: perforated or pierced with suitable sized holes c. Through the tube or
pipe b, and working loosely therein, there passes a rod or spindle d pro-
vided at its upper end with a knob e. The lubricator a is provided with
a loose cover f.
In application the lumps of tallow or other like fatty matter are
placed in the lubricator a round the pipe or tube 6 (the lubricator
being screwed on to the bearing requiring the lubrication). The rod or
spindle d projects through the tube 6 and rests on the moving shaft or
pin to be lubricated. The vibration of the shaft or pin causes the rod
or spindle to work up and down in the tube, and the lubricant is thus
drawn to the required point through the holes c; inasmuch as the rod
or spindle conducts the heat from the bearing to the tube sufficiently to
melt the tallow or. fatty matter required for lubricating the said
bearing.
Having now described our Invention and shown how the same may
be put into practical effect, we would have it understood that what we
claim as our Invention and secured to us by Letters Patent as aforesaid
is, the perforated tube in combination with the cup a and the spindle
d, and the cover f, constituting a lubricator for using tallow and other
like fatty matters, constructed and arranged to operate substantially as
described.
In witness whereof, we, the said William Edward Rumsey and John
Laurence Davies, have hereunto set our hands and seals, this
Eighth day of December, in the year of our Lord One thousand
eight hundred and seventy-four.
WILLIAM EDWARD (L.S.) RUMSEY.
JOHN LAURENCE
(L.S.) DAVIES.
