PROVISIONAL SPECIFICATION left by the said William Paulson and
Richard Paulson at the Office of the Commissioners of Patents on the 27th
February 1878.
WILLIAM PAULSON and RICHARD PAULSON, both of Mountsorrel, near Lough-
borough, in the County of Leicester. "IMPROVEMENTS IN APPARATUS FOR LUBRI-
CATING SPINDLES AND OTHER SURFACES."
The object of our Invention is the prevention of undue consumption and con-
sequent waste of the oil or lubricating matter employed.
În carrying our improvements into effect the reservoir for the oil or lubricating
matter employed may be formed of glass or other suitable material, with a cap or
cover thereto for facilitating the application of fresh supplies to such reservoir, the
cleansing of it, or otherwise. This cap or cover is provided with a small hole through
it, if desired, for the admission of air. The lower part of this reservoir is formed to
admit of the passage up into it of the upper part of a conducting tube by which the
oil or other lubricant is conveyed down to the shaft or other surface to be lubri-
cated. The connection of this tube to the reservoir may be direct by screwing or
otherwise, or through the medium of a plug of wood, cork, or other suitable material.
A portion of this conducting tube within the reservoir is perforated with holes, or
vertical or other suitable openings, and this part of it is provided with a screwed or
otherwise adjustable cap by which the extent of these openings may be regulated to
the extent of flow required. The interior of this conducting tube is fitted with
cotton or other suitable fibre to act in filtering, purifying, and cleansing the oil or
31

page_text: other lubricant in its passage to the spindle or other surface to be lubricated. The
lower end of this conducting tube may also be provided with a perforated cylinder
or nipple which is pressed on to the spindle or surface to be lubricated by the weight
of the reservoir and conducting tube. The under surface of this tube, or of the
cylinder or nipple, corresponds in form with the form of the spindle or surface to be
lubricated, and the friction of contact causes the oil or lubricant to flow as required.
Increase of speed or heat will effect increase in the flow through the perforations to
the parts to be lubricated.
The conducting tube is passed through a plug or tube, which acts as a guide, and
is screwed or otherwise fitted in the bearing of or other connection with the part to
be lubricated. There may also be an inner tube between the conducting tube and
guide, and a pin or other guide or stop may also be used to aid in keeping the parts
in correct relations. By these means the quantity of oil or lubricating matter
allowed to flow is capable of being readily regulated, whilst for differences of speed
the quantity flowing becomes self-regulating, and when motion to the parts ceases
the flow of the lubricant is stopped.
By another arrangement of the parts the reservoir and supply tube therefrom are
stationary, and the openings in the supply tube for the passage thereto of the oil or
lubricating matter are formed above the level of such oil or lubricating matter in
the reservoir, and such oil or lubricating matter is supplied to the tube as required
by a brush or other suitable lifter, and this brush or lifter is operated for the
purpose by leverage acted upon by a projection or projections from the shaft or
surface to be lubricated aided by spring or weight pressure.

CATING SPINDLES AND OTHER SURFACES."
The object of our Invention is the prevention of undue consumption and con-
sequent waste of the oil or lubricating matter employed.
In carrying our improvements into effect the reservoir for the oil or lubricating
matter employed may be formed of glass or other suitable material, with a cap or
cover thereto for facilitating the application of fresh supplies to such reservoir, the
cleansing of it, or otherwise. This cap or cover is provided with a small hole
through it if desired for the admission of air. The lower part of this reservoir is
formed to admit of the passage up into it of the upper part of a conducting tube by
which the oil or other lubricant is conveyed down to the shaft or other surface to
be lubricated. The connection of this tube to the reservoir may be direct by
screwing or otherwise, or through the medium of a plug of wood, cork, or other
suitable material. A portion of this conducting tube within the reservoir is perfo-
rated with holes, or vertical or other suitable openings, and this part of it is pro-
vided with a screwed or otherwise adjustable cap by which the extent of these
openings may be regulated to the extent of flow required. The interior of this
conducting tube is fitted with cotton or other suitable fibre to act in filtering,
purifying, and cleansing the oil or other lubricant in its passage to the spindle or
other surface to be lubricated. The lower end of this conducting tube may also be
provided with a perforated cylinder or nipple which is pressed on to the spindle or
surface to be lubricated by the weight of the reservoir and conducting tube. The
under surface of this tube, or of the cylinder or nipple corresponds in form with the
form of the spindle or surface to be lubricated, and the friction of contact causes the
oil or lubricant to flow as required. Increase of speed or heat will effect increase
in the flow through the perforations to the parts to be lubricated.
The conducting tube is passed through a plug or tube, which acts as a guide and
is screwed or otherwise fitted in the bearing of or other connection with the part to
be lubricated. There may also be an inner tube between the conducting tube and
guide, and a pin or other guide or stop may also be used to aid in keeping the parts
in correct relations. By these means the quantity of oil or lubricating matter
allowed to flow is capable of being readily regulated, whilst for differences of speed
the quantity flowing becomes self-regulating, and when motion to the parts ceases
the flow of the lubricant is stopped.
By another arrangement of the parts the reservoir and supply tube therefrom are
stationary, and the openings in the supply tube for the passage thereto of the oil or
lubricating matter are formed above the level of such oil or lubricating matter in
the reservoir, and such oil or lubricating matter is supplied to the tube as required
by a brush or other suitable lifter, and this brush or lifter is operated for the pur-
pose by leverage acted upon a projection or projections from the shaft or surface
to be lubricated aided by a spring or weight pressure.
But that the Invention may be the better understood, we will by the aid of the
accompanying Drawings proceed to describe means pursued by us in carrying the
same into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows by sectional view an arrangement of apparatus according to our
Invention.
a is the reservoir to contain the oil or lubricating matter. The reservoir may be
formed of glass or of other suitable material; b is a cap or cover to this reservoir
capable of being readily removed and replaced for convenience of fresh supplies of

page_text: the lubricating matter or for cleansing the reservoir; 6¹ indicates the position of a
small hole which may be provided if desired to admit air to the reservoir and
thereby facilitate the escape of the lubricating matter from the reservoir for use by
the conducting tube c by which the oil or other lubricating matter is conducted from
the reservoir a to the surface to be lubricated. This tube c is filled with cotton, or
it may be gauze wire, or other suitable filtering medium by which the oil or other
lubricating matter is filtered and cleansed in its passage through it. The upper
portion of this tube c within the reservoir a may be perforated with fine holes or
slits for the passage of the lubricating matter to the interior of the tube, and the
number of these openings or the length of the vertical slits may be regulated by a
sliding cap or cover d; or we apply a piece of cotton or other fibrous matter to
act as capillary tubes by such being passed through a hole e¹ in the plug e
with the ends of such fibrous material hanging down the outside of the tubes c
and d for the purpose of conveying the lubricating matter up to the upper
portion of the interior of the tube c. The lower portion of this tube c is pro-
vided with a nipple f with a small passage through it from the interior of the
tube c, and the lower end of this nipple is preferred to be of form corresponding
with the surface to be lubricated, by which the flow of the lubricating matter is
stopped when the apparatus is not in motion.
The tube c is connected to the reservoir by a plug of wood, cork, or other
material c¹, and the tube c is held in position in the bearing or connecting part to
be lubricated by passing through the guide g, and this guide may also be provided
with another inner tube g', if desired, and a pin or other means may be employed
to maintain the correct relations of the parts.
Figure 2 shows a slight modification of Figure 1, in which the parts of the tubo
and reservoir are screwed or otherwise firmly fixed together, and the guide gis
formed with a chamber g² and cap g³, and the lower part of the reservoir a or part of
the tube c is provided with a flange a¹ by which the reservoir and tube c may be
allowed a certain amount of play without fear of their being sprung or jerked out of
the guide g. A slight spring h may be applied between the inside of the chamber g²
and the under side of the flange a¹ to prevent the end of the tube c or its nipple from
bearing too much on and thereby wearing away the surface to be lubricated.
In the above arrangements the reservoir with its tube c are capable of free move
ment to a certain extent.
Figure 3 shows another modification of the arrangements by which the reservoir
with its tube c of filtering material may be applied directly to the bearing of the
surface to be lubricated.
Figure 4 indicates another modification in which the passage for the lubricating
matter is regulated by a wire or rod j, one end of which is connected to the sliding
cover d or to wire gauze to regulate the supply to the tube c, whilst the other end
is in position to be operated upon by a projection or stud k applied to the surface
to be lubricated.
Having thus described our Invention and means which we adopt in carrying the
same into effect, we would have it understood that what we claim is the arranging
or combining parts of apparatus for lubricating spindles and other surfaces by con-
ducting the same in adjustable quantities to filtering media applied in feed tubes,
substantially as described.
In witness whereof, I, the said William Paulson, have hereunto set my hand
and seal, this Twenty-first day of August, in the year of our Lord One
thousand eight hundred and seventy-eight
