IMPROVED LUBRICATORS FOR STEAM ENGINES
Year: 1869

page_text: LETTERS PATENT to James Turner and John Turner, of Rochdale, in
the County of Lancaster, for the Invention of "IMPROVED LUBRICATORS
FOR STEAM ENGINES."
PROVISIONAL SPECIFICATION left by the said James Turner and
John Turner at the Office of the Commissioners of Patents, with
their Petition, on the 13th December 1869.
WC, JAMES TURNER and JOHN TURNER, of Rochdale, in the County
of Lancaster, do hereby declare the nature of the said Invention for
"IMPROVED LUBRICATORS FOR STEAM ENGINES," to be as follows:-
This Invention consists in improved apparatus for forcing tallow, oil,
or other lubricating matter into the feed pipe of steam engines before
it enters the throttle valve for the purpose of lubricating the valve and
cylinder. At any convenient position near the feed pipe we place a
small cylinder communicating by a small pipe with the feed pipe, and
to the cylinder is fitted a ram or plunger having in the centre a tube

page_text: with a thread or screw placed in a nut formed in a worm wheel held in
a cross bar carried on standards cast to the small cylinder, and between
the ram and the cylinder there is a gland. The worm wheel is geared
into a worm worked by a ratchet wheel turned one or more teeth at a
time by a catch worked from the valve rod, radius rod, or other working
part of the engine, and for putting the worm in and out of gear with
the worm wheel there is a small eccentric or crank. At the top of the
screwed tube connected to the ram there is a cup and a thumbscrew for
closing and opening the end of the tube, and on the worm wheel there
is a handle wheel for turning the worm wheel by hand when required.
The small cylinder contains the tallow or lubricating matter which is
supplied through the screwed tube, the ram being raised for the purpose
by the handle wheel, and after the thumbscrew is turned to close the
tube the worm is put into gear with the worm wheel, which as it slowly
turns depresses the ram by means of the screwed tube and slowly forces
the tallow or other matter through the small pipe to the feed pipe, from
whence it passes to the valve and cylinder. And for keeping the
lubricating matter in a fluid or soft state we surround the small
cylinder and small pipe with a covering to which steam is supplied.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Turner and John Turner in the Great Scal
Patent Office on the 13th June 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JAMES
TURNER and JOHN TURNER, of Rochdale, in the County of Lancaster,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirteenth day of December, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said James Turner and John Turner, Her
special license that we, the said James Turner and John. Turner, our
executors, administrators, and assigns, or such others as we, the said
James Turner and John Turner, 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

page_text: and lawfully might make, use, excrcise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVED LUBRICATORS FOR STEAM ENGINES,"
upon the condition (amongst others) that we, the said James Turner
and John Turner, our executors or administrators, by an instrument in
writing under our, or their, or one of our or their hands and scals,
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 James Turner and Jolin Turner,
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)
:-
This Invention consists in improved apparatus for forcing tallow, oil,
or other lubricating matter into the feed pipe of steam engines so that
it shall mix with the steam before or after it enters the throttle valve, or
before it enters the steam chest for the purpose of lubricating the slide
valve and cylinder.
The manner in which this Invention is to be performed will be clearly
understood by the following particular description thereof, reference
being had to the figures and letters on the accompanying Sheet of
Drawings, in which Fig. 1 is an outside view, and Fig. 2 a vertical section
of the apparatus complete drawn about half size, and Figs. 3 and 4
are detached views of some of the parts.
At any convenient position near the feed pipe we place a cylinder a
communicating by a small pipe 6 with the feed pipe, and to the cylinder
is fitted a ram or plunger c having in the centre a screwed tube d, and
the ram or plunger is kept tight to the cylinder by a stuffing box and
gland in the usual manner. The screwed tube d is placed in a nut e
fixed in a worm wheel f, the outside of the nut working in a hole in a
cross frame g fixed to standards or pillars h bolted to the flange i of the
cylinder, and to the worm wheel is cast or fixed the bevil wheel k gearing
into the bevil wheel on the shaft m to which is fixed the handle n.
On the frame g there are lugs or bearings o in which are fitted bosses p,
Figs. 2, 3, and 4, having screwed to them a plate q with a small knob r,
and in the bosses there are holes formed eccentric to the lugs for

page_text: carrying a shaft 8 to which is fixed the worm t and the ratchet wheel ",
and the worm is put in and out of gear with the worm wheel as
required by turning the bosses by means of the small knob r, and when
the apparatus is at work the ratchet wheel u is turned one or more
teeth at a time by the catch on the lever 10 which is vibrated by the
valve rod, radius rod, or other working part of the engine. At the top of
the screwed tube d there is at the outside a cup x, and in the inside a
thread to which is fitted the screw y with a knob z, and a rod a¹
extending through the tube, which screw is to be removed when
the tube is to be opened and screwed in tight when the tube has to be
closed. The cylinder contains the tallow or lubricating matter which is
supplied through the screwed tube, the worm being out of gear with
the worm wheel and the ram raised for the purpose by the bevil wheels
and handle. When the cylinder is full the tube is closed by the screw y,
the worm geared with the worm wheel, and motion given to the lever and
catch to turn the ratchet wheel and worm, and as the worm wheel
revolves the nut e brings down the screwed tube and ram and slowly
forces the tallow or other matter through the small pipe b to the feed
pipe from whence it passes with the steam to the slide valve and cylinder,
and when desired a knock-off motion may be applied to shift the catch
from the teeth of the ratchet wheel and prevent the descent of the
piston, and for keeping the lubricating matter in a fluid state we surround
the cylinder and small pipe with a covering and supply steam to the
space between the cylinder and covering.
Having now described the nature and particulars of our said Invention,
and the manner in which the same is to be performed, we desire it to be
understood that we claim, the improved lubricators for steam engines
as herein described and illustrated on the accompanying Sheet of
Drawings.
In witness whereof, I, the said James Turner, for and on behalf
of myself and the said John Turner, have hereunto set my hand
and seal, this Seventh day of June, in the year of our Lord One
thousand eight hundred and seventy.
JAMES TURNER. (L.S.)
