page_text: LETTERS PATENT to John Bruce Sutton, of the City of Manchester,
Mill Furnisher, for the Invention of "IMPROVEMENTS IN SELF-ACTING
LUDRIGAMOS FOR QUAIXA wn Amam Palm R
Sealed the 30th December 1873, and dated the 4th July 1873.
PROVISIONAL SPECIFICATION left by the said John Bruce Sutton at
the Office of the Commissioners of Patents, with his Petition, on
the 4th July 1873.
I, JOHN BRUCE SUTTON, of the City of Manchester, Mill Furnisher,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SELF-ACTING LUBRICATORS FOR SHAFTING AND OTHER BEARINGS," to be as
follows:-
This Invention has for its object the construction of a self-acting
lubricator capable of regulation in the flow of the lubricant to the
greatest nicety, and consists of a glass vessel of a globular or other
suitable shape, having a neck into which a stopper is fitted, which is
elongated so as to allow of its being fitted into the cap of the bearing
requiring to be lubricated. Through this stopper a metallic tube is

page_text: passed which is fitted with an internal tube of smaller diameter, together
forming a telescopic tube capable of being elongated or shortened to suit
any thickness of cap. The upper end of the outer tube is provided with
a screwed connection having an orifice opening into the tube, and in the
centre of this orifice a tapered plug is fixed. A cap is screwed upon the
connection herein-before described, having a fine hole in its centre to
allow of the point of the tapered plug to pass through, so that as such
cap is screwed along the connection the opening surrounding the plug
will be contracted so as to regulate the flow of the lubricant to the
greatest nicety.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Bruce Sutton in the Great Seal Patent Office
on the 3rd January 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BRUCE SUTTON, of the City of Manchester, Mill Furnisher, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fourth day of July, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Bruce Sutton, Her special license
that I, the said John Bruce Sutton, my executors, administrators, and
assigns, or such others as I, the said John Bruce Sutton, 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 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
SELF-ACTING LUBRICATORS FOR SHAFTING AND OTHER BEARINGS," upon the
condition (amongst others) that I, the said John Bruce Sutton, by an
instrument in writing under my hand and seal, 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.

page_text: NOW KNOW YE, that I, the said John Bruce Sutton, 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 thereof, reference being had to the Drawing's
hereunto annexed, that is to say :-
―
This Invention has for its object the construction of a self-acting
lubricator capable of regulation to the greatest nicety in the flow of the
lubricant, and consists of a glass vessel of a globular or other suitable
shape, having a neck into which a stopper is fitted, which is elongated
so as to allow of its being fitted into the cap of the bearing requiring to
be lubricated. Through this stopper a metallic tube is passed which is
fitted with an internal tube of smaller diameter, together forming a
telescopic tube capable of being elongated or shortened to suit any
thickness of cap. The upper end of the outer tube is provided with a
screwed connection having an orifice opening into the tube, and in the
centre of this orifice a tapered plug is fixed. A cap is screwed upon the
connection herein-before described, having a fine hole in its centre to
allow of the point of the tapered plug to pass through, so that as such
cap is screwed along the connection the opening surrounding the plug
will be contracted so as to regulate the flow of the lubricant to the
greatest nicety
lubricator drawn about full size. Fig. 3 is an enlargement of a portion
5 of Fig. 1 for the purpose of shewing the construction more clearly.
In Figs. 1, 2, & 3, A is the reservoir or vessel for containing the
lubricant of a globular or other suitable form, and (though not neces-
sarily) made of glass. B is the stopper,, by preference made of wood,
having a flange B¹ over which a brass cover C is securely fitted, and
) which brass cover screws into a brass bush D attached by cement or
other means to the neck of the glass vessel A, a leather or other washer E
being interposed between the cover and bush, as shewn, to ensure a
more perfect sealing of the vessel at that point. Through the centre of
this stopper B a small tin or other metallic tube F is passed, and inside
such tube F another tube G of smaller diameter slides, thus together
forming a telescopic tube capable of being lengthened or shortened to
suit the thickness of cap of the bearing to which the lubricator is applied.
