TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JEAN
BENJAMIN COQUATRIX, of Lyons, in the Republic of France, Merchant, scud
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by 'Her'
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twenty-seventh day of January, in the fifteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Jean Benjamin Coquatrix, Her especial license, full power, sole privi-
lege and authority, that I, the said Jean Benjamin Coquatrix, my exors,
adiñiors, and assigns, and such others as I, the said Jean Benjamin Coquatrix,
my exors, adñiors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein mentioned,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVED
APPARATUS FOR LUBRICATING MACHINERY;" in which said Letters Patent is con-
tained a proviso obliging me, the said Jean Benjamin Coquatrix, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same is to
be performed, and to cause the same to be inrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same,.
reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
Jean Benjamin Coquatrix, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, is particu-
larly described and ascertained in and by the following description thereof,
reference being had to the Drawing licreunto annexed, and to the letters and
figures marked thereon, that is to say:-
This Invention is designed, firstly, to effect an economy of oil and other
oleaginous substances used in the lubrication of bearings and other frictional
surfaces of machinery; and,
Secondly, to ensure a continuous and uniform supply of lubricating material
to such frictional surfaces.
These objects are effected by the employment of a conical or other suitably
shaped valve, which is capable of being readily adjusted with the greatest
nicety to any required position with respect to its seat by means of a screw on
the stem of the valve, and a spring catch taking into a ring of notchos pro-
vided for the purpose.
In the accompanying Drawing, forming part of this my Specification, Fig. 1
shews my improved apparatus as applied to a lubricating box, the same being
in partial vertical section the better, to explain the construction of the parts;
and Fig. 2 is a sectional plan view taken in the line 1, 2 of Fig. 1. a, a, is
the box for containing the oleaginous matter. It is fitted with an exit pipe.b,
the upper part of which is bored. ont to form the seat for the valve. Cast in
one piece with this pipe is a neck c, which is tapped with a female screw, and
furnished with lateral passagos d, d, to allow of the oil finding its way from
the box down the pipe b. A conical valve e fits the bore of the upper end of
the pipe 6, and it is sustained in an elevated position by means of a screw f
which is cut upon an enlarged diameter of its stem. To this stem a spring
catch g is rivetted, its object being to take into a ring of notches or teeth
formed on the edge of the neck c. The action of this apparatus is as
follows:-Supposing it to be applied to a bearing as slewn at Fig. 3, and the
supply of oil to be cut off by the valve being depressed into its sent, and it is
required to continue the supply, this is effected by the workman in attendance
on the machine turning the valve stem, which action will cause the valve to
rise from its seat and open a passage for the escape of the oil down the pipe
b. In order to prevent the waste of the lubricating material it has been
found requisite to adjust the area of this passage to the supply of oleaginous
substance required for the bearing to which the apparatus is applied; and to
enable the workman to effect this with precision, the spring catch is employed.
By the traverse of this catch over the ring of notches as the valve stem is

page_text: turned by the attendant, an indication is afforded of the area that is opened
for the escape of the oil; thus it may be five, ten, twenty, or thirty notches that
it is necessary for the spring to traverse over before a sufficient rise of the
valve is effected to open the required area, and this having been once ascer-
tained, the workman is at no loss to adjust this apparatus to suit the circum-
stances of the case.
It will be obvious from the above description that the form of the valve is
immaterial, so long as it has a circular tapering periphery, and that the apparatus
may be otherwise modified. An example of this is shown at Fig. 4, where,
instead of the spring catch being a traversing catch, it is affixed to the sta-
tionary neck c, and takes into notches in the stem, the threaded part f being
in this instance fluted. I wish it to be understood, therefore, that I do not con-
fine myself to the exact details shewn and described, but, under the above in
part recited Letters Patent,
I claim, as of my Invention, the manufacture of lubricating apparatus,
wherein the valve past which the lubricating material flows is adjusted by the
application of an axial motion, and at the same time the position of the rising.
valve with respect to its seat is indicated by means of a click or spring.
In witness whereof, I, the said Jean Benjamin Coquatrix, have here-
unto set my hand and seal, this Twenty-sixth day of July, in the
year of our Lord One thousand eight hundred and fifty-two.
