Year: 1885

page_text: I, DANIEL ARTHUR QUIGGIN, of Halton Buildings 44, Chapel Street, Liverpool,
in the County of Lancaster, Engineer do hereby declare the nature of the said
invention for IMPROVEMENTS IN OIL CUPS, OR LUBRICATORS to be as follows:-
My Invention has for its object certain improvements hereinafter more par-
ticularly described in oil cups, or lubricators, whereby they can be more readily
adjusted and operated.
As an example I will describe an oil cup of the pneumatic sight feed type with
the improvements according to my Invention applied thereto. The principal parts
of a pneumatic sight feed oil cup which I will now describe and to which my
improvements can be applied consists of a casing having a glass body, or the
body may be partly of glass and partly of metal. The top, or cover is of metal
and the shank is of metal. The shank is provided with a hole, or passage for the
oil to pass through to the surface to be lubricated; a tube connects the cover and
shank open at both the bottom and top and projecting through the cover a certain
distance. This projecting portion is screwed and is also provided with a slot, or
slots which can be covered more, or less by a regulating screw cap, or nut. Two
holes are provided in the tube at different levels in it, one of which namely the
upper one serves as a means of admitting air to the interior of the cup whilst the
lower one serves to connect the hole, or aperture in the shank with the oil space of
the cup. The screw cap above mentioned is fitted concentrically with a rod which
extends down through the tube and is made to form a valve having its seat over
the hole in the shank so that as the screwed cap is either raised, or lowered, so
are the air and oil passages opened, or closed, or regulated. A plug is provided in
the cap for filling the cup with the oil. To such oil cups I provide a device
whereby an extra amount, or flush of oil can be supplied to the surface to be
lubricated, at any moment without disturbing the normal regulated feed which
existed before the flush and is resumed after flushing. This may be effected by
means of an adjustable valve rod screwing through a cap which has wings, or
projections. Cams, or projections are formed on the cup cover. By these means
the valve of the valve rod can be lifted off its seat and the wings, or projections

quantity, or flush of oil is allowed to flow. When a sufficient quantity has passed
the shank the cap projections are removed from the cover cams or projections on
the valve cap and valve fall together and resume their prior regulated positions.
A spring is preferably used to keep the valve in position and a spring catch may
he also employed to secure the regulating valve rod at any desired position.
A catch is provided to hold the cap in position when placed, or mounted upon the
cover projections, or cams. The cover is provided with a coned aperture and a
coned plug for filling purposes. The plug is provided with a stem which extends
into the cup and having a stop piece upon its end. This provides a facile means
of refilling the cup and at the same time a good seat is formed and the plug can
be easily removed and can be readily re inserted and it is also prevented from
becoming lost, or misplaced.
This Invention is applicable to oil cups or lubricators with, or without sight
feed.
The valve and device above specified may be made to work in either direction,
that is the valve and cap may be either depressed, or raised, for closing, or opening.

page_text: I, DANIEL ARTHUR QUIGGIN, of Halton Buildings, 44 Chapel Street, Liverpool,
in the County of Lancaster, Engineer do hereby declare the nature of the said
Invention for IMPROVEMENTS IN OIL CUPS, OR LUBRICATORS and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My Invention has for its object certain improvements hereinafter more par-
ticularly described in oil cups, or lubricators whereby they can be more readily
adjusted and operated.
As an example I will describe an oil cup of the pneumatic sight feed type with
the Improvements according to my Invention applied thereto. The principal parts
of a pneumatic sight feed oil cup which I will now describe and to which my
improvements can be applied consist of a casing having a glass body, or the body
may be partly of glass and partly of metal. The top, or cover is of metal and
the shank is of metal. The shank is provided with a hole, or passage for the oil
to pass through to the surface to be lubricated; a tube connects the cover and
shank open at both the bottom and top and projecting through the cover a certain
distance. This projecting portion is covered by a cap. Two holes are provided in
the tube at different levels in it, one of which namely the upper one seryes as a
means of admitting air to the interior of the cup whilst the lower one serves to
connect the hole, or aperture in the shank with the oil space of the cup. The cap
above mentioned is fitted concentrically with a rod which extends down through
the tube and is made to form a valve having its seat over the hole in the shank
so that as the cap is either raised, or lowered so is the oil passage opened, or
closed, or regulated. A plug is provided in the cover for filling the cup with oil..
To such oil cups I provide a device whereby an extra amount, or flush of oil can
be supplied to the surface to be lubricated at any moment without disturbing the
normal regulated feed which existed before the flush and is resumed after flushing.
This may be effected by means of an adjustable valve rod screwing through the
cap which has wings, or projections. Cams, or projections are formed on the cup
cover By these means the valve of the valve rod can be lifted off its seat and the
wings, or projections placed, or turned up onto the projections of the cover, and by
these means a large quantity, or flush of oil is allowed to flow. When a sufficient
quantity has passed the shank the cap projections are removed from the cover
cams, or projections and the valve cap and valve fall together and resume their
prior regulated positions. A spring is preferably used to keep the valve in position
and a spring catch may be also employed to secure the regulating valve rod at any
desired position. A catch is provided to hold the cap in position when placed, or
mounted upon the cover projections, or cams. The cover is provided with a coned.
aperture and a coned plug for filling purposes. The plug is provided with a stem
which extends into the cup and having a stop piece upon its end. This provides a

the plug can be easily removed and can be readily re inserted and it is also
prevented from becoming lost, or misplaced.
This Invention is applicable to oil cups or lubricators with, or without sight
feed.
The valve and device above specified may be made to work in either direction,
that is the valve and cap may be either depressed, or raised for closing, or
opening.
That this Invention may be more clearly understood, I have hereunto annexed
a sheet of Drawings which make a part of this Specification and are illustrative of
and sufficient to enable any skilled person to put the Invention into practice. The
Drawings are marked with letters and figures of reference, corresponding with
those in the following description and like letters. and figures are used to denote
the same, or corresponding parts throughout the various views and figures.

and h
With reference to the Drawings a designates the body of the oil cup, which may
be entirely of glass with a metal bottom and cover, as shown at Figures 1 and 2,
or the body a of the oil cup may be of glass with metal guards as shown at
Figures 5 and 6, or where a sight feed is not required the body a may be wholly
of metal. b is the top, or cover of the oil cup and c is the bottom of the oil cup,
the bottom c being provided with a shank d for securing the oil cup to the part to
be lubricated. The shank d has a duct, or passage e through which the oil passes
to the part to be lubricated. In the example shown at Figures 1 and 2 the cover b
and the bottom c are connected by a tube f which forms part of and extends from
the cover b and screws into the bottom c so connecting the top and bottom and
securing the glass body a between them, the joints being made between the glass
body and the top and bottom by any suitable packing. The tube f is extended
above the cover b a certain distance and is covered by a cap i. Two holes
are provided in the tube fat different levels, the upper hole h serving as a means
of admitting air through the tube f into the cup a and the lower hole g serving for
the passage of oil from the cup a into the tube fand hence to the duct, or passage e
to the surface to be lubricated. The portion of the tube f which projects above the
cover b is surmounted by a cap i of size to leave an annular passage between the
said cap and the tube f.-The cap i is fitted with a rod k which is screwed through
the top of the cap i and is provided with a head having slots on its periphery.
The rod k extends concentrically down the tube f and its lower end is so made as
to form a valve having its seat over the duct, or passage e in the shank d. The
rod passes easily through the top of the tube f, a space being left for the passage
of air to the tube. The rod k is provided with a collar and between this collar
and the top of the tube f there is a spiral spring 3 the object of which is to keep
the cap i aud the valve k¹ of the rod k down and at the same time to permit of the
rod k. being raised when it is required to give a flush of oil through the duct e.

page_text: The regulation of the feed of oil through the hole g and the duct e is effected by
means of the rod k and its valve / by raising, or lowering the rod k by means of
its screwed portion in the cap i. The cap i is provided with a spring locking
pawl m which takes into the slots on the head of the rod k. and holds the rod k
in any position which it may be set. The cap i is also provided with two feet i¹
and the cover b is provided with two recesses b¹ corresponding in size to the said
feet ¹. The cover b is also provided with a spring pawl n which takes into a slot
in a milled rim on the cap i for locking the cover i when the feed of oil is on,
namely when in the position shown at Figure 1. By holding back the spring
pawl the cap i and the rod k can be turned in their set position until the feet i
come into the recesses 61 and thereby the cap is lowered until the valve ¹ shuts off
the feed of oil to the duct e. To give a flush of oil the cap i and rod k are raised
which can be done when the feed of oil is on, or when the feed of oil is off without
interfering with the set position of the rod k and its valve k¹. The cover b is
provided with a plug p for filling the cup a with oil the said plug p having a stop p¹
to prevent it being lost. The cover b is also provided with holes q to receive a
cross foot spanner for unscrewing the cover.
In the example shown at Figures 5. 6. 7 and 8. the metal of the bottom c is
carried up to form a guard to the glass body a. and the cover b is screwed onto the
upper portion of this metal. The lower portion of the tube f in this case makes
joint by means of a leather, or other washer with the bottom c instead of screwing
into the bottom c as shown in Figure 1. The rod k and the cap i are of similar
construction to that shown at Figure 1, but in this case side projections are
substituted for the feet on the cap i and these side projections rest on shoulders 6¹
formed on the cover b and which take the place of the provisions for raising and
lowering the cover b shown in Figure 1.
In the modification shown at Figure 9 the spiral spring k³ is placed outside of
the tube f, and comes between a collar k³ on the said tube and the underpart of
the cap. The screwed portion of the rod k is of larger diameter than that shown
in the other examples. This arrangement facilitates the withdrawal of the rod k.
When it is not required that the oil cup should be a sight feed lubricator that
portion of the tube f between the cover b and the bottom c is omitted. This
portion of the tube f being used only when the cup is a sight feed lubricator. In
this latter case the air travels down the tube f escaping into the cup a through the
hole h ascending in a bubble or bubbles through the oil contained in the cup, thus
rendering the time and quantity of the feed visible. When the tube f is dispensed
with any convenient means of securing the top and bottom of the cup, such as that
shown at Figure 5 may be adopted.
The means herein described of regulating the feed, combined with the means
herein described of flushing and the means of cutting off the feed can be applied
to other known types and forms of oil cups than those herein shown.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
First. The combination with an oil cup in which a means for regulating the
supply of oil such as described is employed of means such as described or any
mere modification thereof whereby a flush of oil can be supplied to the bearing or
journal and wherein the regulation of any given set feed will remain undisturbed
as set forth
Second. The combination with an oil cup in which a means for regulating the
supply of oil such as described is employed of means such as described, or any
mere modification thereof, whereby such supply can be stopped wherein the
regulation of any given set feed will remain undisturbed as set forth.
Third. The combination with an oil cup in which a means for regulating the
supply of oil, such as described, is employed, of means whereby a flush of oil can

page_text: be supplied to the bearing or journal, and means whereby such supply can be
stopped such as described, or any mere modification thereof, wherein the regulation
of any given set feed will remain undisturbed as set forth.
Fourth. The means substantially herein described applied to an oil cup whereby
a flush of oil can be supplied to, or the supply of oil can be cut off from the bearing
or journal, consisting of a cap i and spring ³, constructed and operating substan-
tially as set forth with reference to the Drawings.
