GEORGE VAILE, of the Parish of Cuckney, near Mansfield, County of Nottingham,
Mechanical Engineer. "AN IMPROVED APPARATUS FOR LUBRICATING SPINDLES,
SHAFTS, AND OTHER SURFACES SUBJECT TO FRICTION."
My Invention has for its object the construction and arrangement of apparatus in
which a moveable tube, acted upon by a small spiral spring, is adapted to convey
oil or lubricating material in a purified condition to any surface to which the same
is intended to be applied, and transmitting only a regulated quantity of such
material, thereby avoiding waste and unnecessary consumption thereof. The said
moveable tube is contained within another tube, closed at the top, and having a
spiral spring capable of acting on the said moveable tube, in order to keep it down
on the frictional surface intended to be lubricated, and thereby prevent waste. The
said outer tube is screwed into the bottom of an oil cup, within which is fitted a
double grating formed by two perforated disc plates, with cotton, wool, or other
suitable porous material inserted between them, by passing through which the oil is
filtered and purified before it enters the said internal tube leading to the spindle or
other part required to be lubricated. The pressure applied to the upper perforated
plate, and the supply of filtered and purified oil through the grating, are regulated
by a tightening collar. The filtered and purified oil is admitted to the said
outer and inner tubes from the oil cup through vertical apertures formed in the
tubes, and it is prevented from passing outside the said inner tube by means of a
washer.
Instead of employing the grating as above stated, the oil is sometimes filtered
and purified, as required, by inclosing the tube containing the spring within another

page_text: tube with an open top containing filtering and purifying porous material, into
which tube oil can enter from the external cup.
The lubricator above described may be varied in form so as to adapt it for
different uses.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said George Vaile in the Great Seal Patent Office on the 23rd December
1876.
GEORGE VAILE, of the Parish of Cuckney, near Mansfield, County of Nottingham,
Mechanical Engineer, "AN IMPROVED APPARATUS FOR LUBRICATING SPINDLES,
SHAFTS, AND OTHER SURFACES SUBJECT TO FRICTION."
My Invention has for its object the construction and arrangement of apparatus in
which a moveable tube, acted upon by a small spiral spring, is adapted to convey
oil or lubricating material in a purified condition to any surface to which the same
is intended to be applied, and transmitting only a regulated quantity of such
material, thereby avoiding waste and unnecessary consumption thereof. The said
moveable tube contained within another tube, closed at the top, and having a
spiral spring capable of acting on the said moveable tube, in order to keep it down
on the frictional surface intended to be lubricated, and thereby prevent waste. The
Baid outer tube is screwed into the bottom of an oil cup, within which is fitted a.
double grating, formed by two perforated disc plates with cotton, wool, or other
suitable porous material inserted between them, by passing through which the oil is
filtered and purified before it enters the said internal tube leading to the spindle or
other part required to be lubricated. The pressure applied to the upper perforated
plate, and the supply of filtered and purified oil through the grating, are regulated
by a tightening collar. The filtered and purified oil is admitted to the said outer
and inner tubes from the oil cup through vertical apertures formed in the tubes, and
it is prevented from passing outside the said inner tube by means of a washer.
Instead of employing the grating as above stated, the oil is sometimes filtered and
purified, as required, by enclosing the tube containing the spring within another
tube with an open top containing filtering and purifying porous material, into which
tube oil can enter from the external cup.
The lubricator above described may be varied in form so as to adapt it for
different uses.
Having thus stated the nature of the said Invention, I will proceed to describe
more particularly in what manner the same is to be performed by reference to the
accompanying Drawings, in which are represented the parts above referred to.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a vertical section, and Fig. 2 a horizontal section of one form of lubri-
cator. Figures 3 and 4 are similar views of another form.
Fig. 5 is a section of a lubricator adapted for use in railway carriage axle boxes.
Fig. 6 is a section, and Fig. 7 a plan or horizontal view of a lubricator adapted for
ordinary carriage wheels.
In these several Figures the same letters of reference indicate corresponding
parts.
A is an oil cup of suitable form, into the lower part of the interior of which is
fitted a double grating B, composed of two circular perforated plates, between which
is inserted cotton, wool, or other porous substance adapted for filtering and purifying
the oil before it passes to the spindle or part required to be lubricated. C is a
collar, by means of which the requisite pressure is applied to the grating in order to
regulate the supply of oil through it into the tube D, whence it passes to the
spindle or part required to be lubricated. The grating B is fitted on to a shoulder
formed at the lower part of the cup A, leaving an oil chamber below the grating.

page_text: thereby admitting of the grating being pressed downwards, and of the oil being
caused to pass into the chamber through perforations into the tube E, and thence
through openings into the inner tube D, which is contained within the tube E,
screwed into the lower part of the cup A. The inner tube D is moveable within
the fixed tube E, and is pressed upon at the top by a spring F inserted between the
top of the tube D and the closed upper end of the tube E, by which means the
tube D is kept in contact with the spindle or frictional surface to be lubricated. G
is a washer of india-rubber or other suitable material for preventing oil from
passing down outside the tube D.
By means of the arrangement described oil is supplied from the chamber at the
bottom of the cup A in a filtered and purified state, and in duly regulated quantity,
and passing through the inner tube D is conveyed directly to the spindle or
frictional surface to be lubricated, on to which the tube D is pressed by the action of
the spring F, so that when the machinery is stopped the oil does not waste as in
ordinary arrangements.
The lubricator, represented in Figures 3 and 4, consist of an oil cup A, as before
described, but the porous material for filtering and purifying the oil, instead of
being inserted in a double grating, is contained in an outer tube H, open at top,
from a chamber at the bottom of which tube oil is supplied through tubes E and D,
as before described.
The lubricator represented in Fig. 5 is specially adapted for screwing into the
grease holes of railway carriage axle boxes, and is constructed as in the case last
described.
The form of lubricator represented in Fig. 6 is specially adapted for ordinary
carriage wheels, and is intended to be inserted in the nave of the wheel. It con-
sists of an oil cup A made in the form of a wedge, with a cap secured by two or
more screws on to the nave, and is constructed with the same internal arrangements
as that represented in Fig. 1, and described above.
At Fig. 8 is represented an indicator intended to show the quantity of oil con-
sumed. a is a needle projecting through the lid of the oil cup A, to which needle
is connected a small float b of any suitable substance. c is a screw which serves as
a packing to prevent oil from passing outside of the moveable tube D.
Figures 9 and 10 represent an apparatus with the tube for containing the
filtering substance, composed of zinc or other suitable material perforated. This tube
is connected to a nut b, which has a recess to allow of the oil passing into the tube
E, as shewn in Fig. 10; d is a screw for regulating the pressure on the filtering
substance; and e is a screw plug for regulating the pressure of the spring F on the
moveable tube D. This screw plug may be applied in all cases.
Fig. 11 shows the upper plate, and Fig. 12 the lower plate of the double
grating B.
Having thus described the nature of the said Invention, and in what manner the
same is to be performed, I hereby declare that what I claim as of my Invention is
the construction of lubricating apparatus in which oil is filtered and purified and
conveyed to spindles or frictional surfaces (required to be lubricated), and the waste
of oil is prevented by the means herein-before described.
In witness whereof, I, the said George Vaile, have hereunto set my hand
and seal, the Fourth day of November, in the year of our Lord One
thousand eight hundred and seventy-six.
