IMPROVEMENTS IN LUBRICATORS
Year: 1857

page_text: LETTERS PATENT to William Oxley, of the City of Manchester, Engineer,
and Hugh Strath, of the same Place, Foreman, for the Invention of
"IMPROVEMENTS IN LUBRICATORS."
Sealed the 15th September 1857, and dated the 9th April 1857.
PROVISIONAL SPECIFICATION left by the said William Oxley and Hugh
Strath at the Office of the Commissioners of Patents, with their Petition,
on the 9th April 1857.
We, WILLIAM OXLEY, of the City of Manchester, Engineer, and HUGH
STRATH, of the same Place, Foreman, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN LUBRICATORS," to be as follows:-
Our Invention consists in an improved combination of parts for taking oil
or other lubricating material out of a suitable vessel and supplying it in any
required quantity to the shaft or other article to be lubricated. A shaft with
a projecting crank is made to revolve in the usual manner; to this crank is
attached a spring or other agent, which dips into the lubricating material and
delivers a portion thereof to a hollow tube or guide, from which it is conveyed
to the shaft or other article to be lubricated. By making the hollow tube or

page_text: guide to swivel on a centre excentric to that of the crank, the quantity of
lubricating material delivered by the spring or other agent can be regulated as
required.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Oxley and Hugh Strath in the Great Seal Patent
Office on the 29th September 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
OXLEY, of the City of Manchester, Engineer, and HUGH STRATH, of the same
Place, Foreman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of April, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said William Oxley and Hugh Strath, Her special licence that we, the
said William Oxley and Hugh Strath, our executors, administrators, and
assigus, or such others as we, the said William Oxley and Hugh Strath, 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, 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," upon
the condition (amongst others) that we, the said William Oxley and Hugh
Strath, our executors or administrators, by an instrument in writing under our,
or their, or one of our or 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 immediately after the
date of the said Letters Patent.
NOW KNOW YE, that we, the said William Oxley and Hugh Strath, do
hereby declare the nature of our 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):—
The nature of our said Invention consists in an improved combination of
parts for taking oil or other lubricating material out of a suitable vessel and
supplying it in any required quantity to the journal and bearing, or other
article to be lubricated.

page_text: In order that our Invention may be fully understood and readily carried
into effect, we will proceed to describe the means pursued by us, reference
being had to the accompanying Sheet of Drawings, and to the figures and
letters marked thereon.
1
Figure 1 is a side view of our improvements in lubricators; and Figure 2
is a front view in section of the same. a is the journal, and 6 the bearing to
be lubricated; c is a shaft, forming part of the lubricator; this shaft revolves
in the frame d, and to it is fixed the crank c. The shaft c is turned round by
the band f, passing under the axle or shaft to be lubricated and over the
groove pulley g, or in any other convenient manner; to the crank e is attached
an elastic spring or conductor e¹. We prefer to have this conductor of fine
tempered steel, as the slight friction on the points of the wiper or scraper
least effects its proper set or curve.
As the shaft c revolves the conductor e¹
dips into the oil or other lubricating material contained in the vessel h, and
delivers a portion thereof to the journal to be lubricated through the tube i,
the lower end of which is secured to the lid of the bearing in the usual
manner. The lubricating material is guided into the tube i by the conducting
wire j, which is also a regulator, the lower end of which fits in the piece k,
to which is also fixed the wiper or scraper 7. This wiper or scraper 7 has two
projections, but one or more may be used; and the wire j is capable of moving
in the piccek for the purpose of setting the said wire nearer to or further
from the scraper b, l, as shewn by dotted lines in Figure 2. The mode of
operation is as follows:-When the shaft or axle to be lubricated revolves, the
band communicates motion to the shaft c in the direction of the arrow in
Figure 2; the spring or conductor e in passing through the lubricating mate-
rial carries forward a portion thereof, part of which is removed by the wiper
or scraper 7, and the remainder is deposited on the wire j, along which it is
guided to the tube i; by moving the wire j into the position shewn by the
dotted lines in Figure 2, the end of the wire is brought further from the
scraper 1, consequently the spring e¹ in revolving remains less time in contact
with it, and very little of the lubricating material is deposited on the wire j;
but when the wire is moved into the position shewn by the dotted lines at j¹
the contrary effect takes place; by this means the quantity of lubricating mate-
rial delivered to the journal or bearing, or other article to be lubricated, can
be regulated as required.
Having thus described the nature of our Invention, and the manner of per-
forming the same, we would observe that we do not limit ourselves to the
particular arrangement herein set forth, as the same may be modified to suit
the object to be lubricated; but what we claim is, the conductor or spring e¹

page_text: and the adjustable conductor or regulator j when used for the purposes
described.
In witness whereof, we, the said William Oxley and Hugh Strath,
have hereunto set our hands and seals, this- Twenty-sixth day of
September, in the year of our Lord One thousand eight hundred
and fifty-seven.
