CONSTRUCTION OF LUBRICATORS'
"

PROVISIONAL SPECIFICATION left by the said James Heginbottom and
Samuel Green at the Office of the Commissioners of Patents on the 30th
January 1877
JAMES HEGINBOTTOM and SAMUEL GREEN, both of Oldham, in the County of
Lancaster "IMPROVEMENTS IN THE CONSTRUCTION OF LUBRICATORS'
"
This Invention relates to the construction of hand lubricators for applying tallow
or other similar semi-fluid lubricating material or compound to shafts or other
frictional surfaces requiring to be lubricated.
The Invention consists principally of a cylinder to contain the tallow or lubri-
cating material, and a piston working therein for forcing the same out through a
tube or nozzle screwed into one end of the cylinder
The piston has a central bole through it which is tapped with a screw thread,
and fits on to a screw passing through the centre of the other end of the cylinder.
Outside the cylinder end the screw has attached to it a disc or wheel with several
projections, by means of which the screw can be turned round by the finger and
thumb whilst the cylinder is held in the hand, and thus it will be evident that by
turning the screw more or less any desired quantity of tallow or other lubricating
material may be forced through the nozzle and applied to the part desired
The piston is prevented from turning round with the screw by means of a guide
wire passing through a second hole in the piston. The cylinder is filled with tallow
or other lubricant by unscrewing the tube or nozzle above mentioned.

This Invention relates to the construction of lubricators for applying tallow or
other similar semi-liquid lubricating material or compound to mule rollers and
shafts or other fictional surfaces requing to be lubricated
Such being the nature and object of our said Invention, we will now proceed to
descube in detail the manner in which the same is to be or may be performed, and
in order that the same may be clearly understood, we have annexed hereunto &
Sheet of Drawings illustrative thereof, and have marked the same with figuies and
letters corresponding with those in the following explanation thereof,-
Fig 1 in the annexed Drawing is a side elevation, Fig 2, a longitudinal section,
and Fig 3; a cross section of an improved lubricator made according to our
Invention
The Invention consists principally of a cylinder a, a, to contain the tallow or
lubricating material, and a piston b, b, working therein for forcing the same out
through a tube or nozzle c, c, screwed into one end of the cylinder
The piston b, b, has a central hole through it which is tapped with a screw thread,
and fits on to a sciew d, d, passing through the centre of the other end of the
cylinder a, a Outside the cylinder end the sciew d, d, has attached to it a disc or
whcel e, e, with several notches or projections, by means of which the screw d, d,
can be turned round by the finger on thumb whilst the cylinder a, a, is held in
the hand, and thus it will be evident that by turning the screw d, d, more or less
any desired quantity of tallow or other lubricating material may be forced through
the nozzle c, c, and applied to the part desired, or if desued the disc wheel e, e, may
be actuated by mechanical means
The piston is prevented from turning round with the screw by means of a guide
wie o bff passing through a second hole or notch in the piston The cylinder
a, a, is filled with tallow or other lubricant by unscrewing the tube oi nozzle c, c,
above mentioned
Having now described the nature and object of our said Invention, together with
the manner in which the same is to be or may be performed or called into practical
eflect, we wish it to be understood that we claim as our Invention, the improved
construction of lubricator for applying tallow or other similar semi-fluid lubricating
material or compound to mule rollers, shafts, or other fictional surfaces requiring
be to lubricated, substantially as her em-before particularly described and illustrated
by the Diawings annexed
In witness whereof, I, the said James Heginbottom (on behalf of myself and
the said Samuel Green have), have hereunto set my hand and seal, this
Twenty-sixth day of July, in the year of our Loid One thousand eight
hundied and seventy-seven
