IMPROVEMENTS IN LUBRICATORS
Year: 1884

page_text: We JOHN BAGULEY Brass Finisher and WALTER EASTWOOD Brass Founder both
of Ashton under Lyne in the County of Lancaster do hereby declare the nature of
the Invention for IMPROVEMENTS IN LUBRICATORS to be as follows :-
This Invention relates to the construction of lubricators for supplying oil or
other lubricating fluid to the cylinders and valves of steam engines or to the
bearings of shafts or other surfaces requiring to be lubricated.
The oil or other lubricating fluid is placed in a closed vessel or cistern from the
top of which proceeds a pipe (or pipes) for conveying or supplying the oil or other
lubricating fluid to the cylinder or other place to be lubricated.
This supply pipe is provided at any convenient part with a short piece of glass
tubing (known as a sight feed) whereby the rate of the supply of lubricant
can at any time be inspected. The said pipe is also furnished with a regulating
tap or valve to regulate the supply, and with a stop tap for cutting off the supply
altogether.
The closed vessel or oil cistern is provided with a cup and screw valve at the top
for filling the same when required and also with a tap at or near the bottom for
emptying the same.
At a convenient place above the level where the oil or lubricant is to be utilized
is placed a cistern to contain condensed water from the steam pipes or water from
any other source and from this cistern a pipe descends and communicates with
the bottom of the closed oil vessel or cistern which pipe is furnished with a stop
cock.
When this stop cock is opened the water from the upper cistern descends the
pipe into the bottom of the closed oil vessel and the oil being lighter than the
water floats upon the top thereof.
If the stop tap in the supply pipe is now opened the pressure of the water will
force the oil or other lubricating fluid along the supply pipe to the place where the
oil is required the rate of supply being regulated by opening or closing the
regulating tap or valve above referred to and so long as the stop taps remain open
and there is any oil or lubricating fluid in the closed vessel this supply will remain
constant.

page_text: In cases where it is desired to utilize the ordinary oil cups, the closed oil vessel
is dispensed with and a pipe from the water cistern is led into the bottom of each
oil cup A stand-pipe open at the top is screwed or otherwise fixed into the central
orifice of the cup and as the water raises the oil the latter overflows down the stand
pipe and is conveyed to the place required.
Where the pressure from the town's water pipes can be had the raised water
cistern will not be required as the pressure in the main pipes will be sufficient for
all purposes.

We JOHN BAGULEY Brass Finisher and WALTER EASTWOOD Brass Founder both
of Ashton-under-Lyne in the County of Lancaster do hereby declare the nature of
our Invention for "IMPROVEMENTS IN LUBRICATORS and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
This Invention relates to the construction of lubricators for supplying oil or
other lubricating fluid to the cylinders, piston rods, and valves of steam engines or
to the bearings of shafts or to slides or other surfaces requiring to be lubricated.
The nature of our Invention and the manner in which the same is to be or may
be, carried into practical effect will be readily understood on reference to the
annexed Drawings and the following explanation thereof.
Fig. 1. is an elevation of our improved apparatus. The oil or other lubricating
fluid is placed in a closed vessel or cistern a, a from the top of which proceeds a
pipe (or pipes) b, b for conveying or supplying the oil or other lubricating fluid to
the cylinder or other place to be lubricated.
This supply pipe b, b is provided at any convenient part with a short piece of
glass tubing c, c (known as a sight feed) whereby the rate of the supply of
lubricant can at any time be inspected. The said pipe b, b is also furnished with a
regulating tap or valve d to regulate the supply and with a stop tape for cutting
off the supply altogether.
The closed vessel or oil cistern a, a is provided with a cup and screw valve fat
the top for filling the same when required, and also with a tap g at or near the
bottom for emptying the same.
At a convenient place above the level where the oil or lubricant is to be utilized
is placed a cistern h, h to contain condensed water from the steam pipes, or water
from the pumps or from any other source, and from this cistern a pipe i, i descends
and communicates with the bottom of the closed oil vessel or cistern a, a which
pipe is furnished with a stop cock k.
When this stop cock k is opened the water from the upper cistern h, h descends
the pipe i, i into the bottom of the closed oil vessel a, a and the oil being lighter
than the water floats upon the top thereof.
If the stop tape in the supply pipe b, b is now opened the pressure of the water
will force the oil or other lubricating fluid along the supply pipe b, b to the place
where the oil is required, the rate of supply being regulated by opening or closing
the regulating tap or valve d, above referred to, and so long as the stop taps e and k
remain open and there is any oil or lubricating fluid in the closed vessel a, a, this
supply will remain constant.
In cases where it is desired to utilize the ordinary oil cups see Fig. 2 the closed
oil vessel a, a is dispensed with and a pipe from the water cistern h, h is led into
the bottom of each oil cup l, l.
A stand-pipe m, m open at the top is screwed or otherwise fixed into the central
orifice of the cup, and as the water raises the oil, the latter overflows down the
stand pipe m, m and is conveyed to the place required.
When the pressure from the towns water pipes can be had, the raised water
cistern h, h will not be required as the pressure in the main pipes will be sufficient
for all purposes.
If required an additional pipe b², 61 for "flushing" provided with a stop tap e¹
inay be attached.

page_text: If the lubricator is to be used for tallow the cistern a, a or the cup 1, 1 must be
fixed in such a position that the tallow shall be kept warm but it must not be
allowed to reach the boiling point.
In applying our lubricator to locomotive engine cylinders the lubricant will flow
into the cylinders, when the steam is shut off whilst going down an incline.
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed we declare that what
we claim is the improvements in lubricators substantially as hereinbefore described
and illustrated by the Drawings annexed consisting of a closed or open vessel or
cistern having at or near the top a pipe furnished with a "sight feed" to convey,
the oil to the part to be lubricated, and at or near the bottom a pipe to introduce
water (under pressure) beneath the oil, whereby the pressure of the water acting
beneath the oil or other lubricant in a closed vessel forces the said lubricant
along a supply pipe to the cylinder or other place where the lubricant is to be
applied, the said supply pipe being provided with a stop cock and a regulating tap
or valve as described and shown.
