Year: 1862

page_text: LETTERS PATENT to August Conrad Dewies, of Nicholl Square, Alders-
gate Street, in the City of London, for the Invention of "AN IMPROVED
LUBRICATOR."
Sealed the 1st May 1863, and dated the 4th November 1862.
PROVISIONAL SPECIFICATION left by the said August Conrad Dewies
at the Office of the Commissioners of Patents, with his Petition, on the
4th November 1862.
I, AUGUST CONRAD DEWIES, of Nicholl Square, Aldersgate Street, in the City
of London, do hereby declare the nature of the said Invention for "AN IMPROVED
LUBRICATOR," to be as follows:-
Take a glass or other vessel of any convenient and if desired ornamental
shape, for example, a glass phial, into the neck thereof fit a stopper of cork or
other suitable material, air-tight; through this stopper pass a small metal tube,
open at one end and closed at the other end; puncture the closed end at its
centre with a fine point, and on the side of the said tube at a short distance
from the aforesaid stopper form another fine hole. Then proceed to withdraw
the said stopper with its attached tube, and nearly fill the phial with the
lubricating fluid, which should be very limpid. Then insert the stopper
aforesaid, taking care to place the punctured end of the tube thereof
within the phial, leaving the open end of the said tube outermost; having
done this invert the phial, the effect of which will be that the air contained in

page_text: the uppermost part of the phial will force out the lubricating matter through
the hole in the side of the tube, the lubricating matter passing out at the open
end of the tube. Now suppose this open end of the tube to be placed over
the journal of an axle shaft, spindle, or other rubbing surface, as the same
rotates or reciprocates the effect will be to aspire the lubricating matter from
the vessel containing same, and thereby cause a partial vacuum in said vessel,
so that when the axle or other rubbing surface is not rotating or reciprocating,
the lubricating matter will be kept up within the tube by capillary attraction,
and as the axle or other rubbing surface again rotates or reciprocates a portion
of atmospheric air will pass up the tube aforesaid through the punctured end
thereof into the upper part of the glass vessel, and again displace a propor-
tional quantity of the lubricating matter, and so on successively, thereby only
discharging the lubricating matter during the rotations or reciprocations
of the axle, or other rubbing surfaces, thereby preventing escape and
waste of the lubricating matter when the axle is at rest, and it is this
peculiar principle of construction which constitutes this Invention of an
improved lubricator.
The above mode of constructing lubricators is susceptible of various modi-
fications, according to the size of the part to be lubricated, and the description
of machinery to which this improved lubricator is to be applied.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said August Conrad Dewies in the Great Seal Patent Office on
the 4th May 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, AUGUST
CONRAD DEWIES, of Nicholl Square, Aldersgate Street, in the City of London,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of November, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her. heirs and successors, give and grant unto I,
the said August Conrad Dewies, Her special licence, that I, the said August.
Conrad Dewies, my executors, administrators, and assigns, or such others as I,
the said August Conrad Dewies, 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

page_text: 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 LUBRICATOR," upon the condition (amongst others) that I, the
said August Conrad Dewies, my executors or administrators, by an instru-
ment 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 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. I, the said August Conrad Dewies, 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, that is to say:-
Take a glass or other vessel of any convenient and if desired ornamental
shape; for example, a glass phial; into the neck. thereof fit a stopper of
cork or other suitable material air-tight; through this stopper pass a small
metal tube open at one end, and closed at the other end; puncture the
closed end at its centre with a fine point, and on the side of said tube at
a short distance from the aforesaid stopper form another fine hole; then
proceed to withdraw the said stopper with its attached tube, and nearly fill the
phial with the lubricating fluid, which should be very limpid. Then insert
the stopper aforesaid, taking care to place the punctured end of the tube
thereof withing the phial, leaving the open end of the said tube outermost ;
having done this invert the phial, the effect of which will be that the air
contained in the uppermost part of the phial will force out the lubricating
matter through the hole in the side of the tube, the lubricating matter passing
out at the open end of the tube.
Now suppose this open end of the tube to be placed over the journal of an
axle, shaft, spindle, or other rubbing surface, as the same rotates or reciprocates,
the effect will be to aspire the lubricating matter from the vessel containing
same,, and thereby cause a partial vacuum in said vessel, so that when the axle
or other rubbing surface is not rotating or reciprocating, the lubricating matter
will be kept up within the tube by capillary attraction, and as the axle or other
rubbing surface again rotates or reciprocates, a portion of atmospheric air
will pass up the tube aforesaid through the punctured end thereof into the
upper part of the glass vessel, and again displace a proportionate quantity of
the lubricating matter, and so on successively, thereby only discharging the
lubricating matter during the rotations or reciprocations of the axle or other
rubbing surfaces, thereby preventing escape and waste of the lubricating matter

page_text: when the axle is at rest, and it is this peculiar principle of construction which
constitutes this Invention of an improved lubricator. The above mode of con-
structing lubricators is susceptible of various modifications according to the
size of the part to be lubricated, and the description of machinery to which
this improved lubricator is to be applied.
In order to explain my said Invention as completely as possible, I now
proceed to describe the best means I am acquainted with for carrying the same
into practical effect, reference being had to the illustrative Sheet of Drawings
accompanying these Presents, and to the numeral figures and letters of
reference marked thereon respectively, as follows:-
DESCRIPTION OF THE DRAWING.
Figure 1 represents a transverse and vertical section of my improved lubri-
cator as it would appear when in use and adapted to a plummer block,
carrying a revolving shaft; Figures 2 and 3 are modifications of the lubricator
and Figure 4 is a bottom plan view of Figure 2, hereinafter. described. At
each of the foregoing Figures, I employ similar letters of reference to .denote
corresponding parts, in so far as such parts appear or can be seen at each of
such said Figures respectively.
A is a portion of an ordinary plummer block; B the journal of a revolving
shaft; C a hole formed through the upper part or cap of the plummer block, and
also through the upper brass D. The hole C is intended to receive my improved
lubricator, the construction of which is as follows:-E is a glass vessel, which
may be of any other form, as at Figures 2 and 3. G is a metal be en tirely
open at the end 1, and punctured with small holes at. 2 and 3, or there may be
more than one hole through the side of the tube G; H is a piece of cork.
fitting tightly around the tube G; the cork H should fit tightly in the neck a
of the vessel E.
In applying my improved lubricator to machinery, the vessel E is first
nearly filled with oil or other lubricating fluid. The cork H with its tube G
is then inserted in the neck of the vessel E, which is afterwards inverted, and
the outer part of the tube G inserted in the hole C of the plummer block A.
The effect of thus constructing a lubricator is to cause the lubricating fluid to
be given off in small quantities regularly and in proportion to the speed of the
journal to which it, is applied, the lubricant ceasing to be given off when the
journal is at rest.
.
At Figures 2 and 3, I have represented the vessels E with a screw formed
inside, the necks thereof to ensure more perfect attachment of same to the
corks H.

page_text: I have also shewn a flange piece b, fixed to the tube G for the cork H to
rest upon.
Having now fully described and set forth the nature and object of my said
Invention for "An Improved Lubricator," together with the best means I am
acquainted with for carrying the same into practical effect, I would remark in
conclusion that I hereby declare my Invention to consist in, and I claim, the
combination of parts above described and represented in the construction of a
lubricator, as constituting an improvement in that article.
In witness whereof, I, the said August Conrad Dewies, have hereunto
set my hand and seal, this Twenty-seventh day of April, in the year of
Lord One thousand eight hundred and sixty-three.
AUGUST CONRAD DEWIES. (L.S.)
