IMPROVEMENTS IN LUBRICATORS
Year: 1885

page_text: I JOHN HOLT of Bankfield Cadaw, Radcliffe in the County of Lancaster
Millwright, do hereby declare the nature of my invention for IMPROVEMENTS IN
LUBRICATORS to be as follows
-
This invention relates to the construction of lubricators employed for supplying
oil or tallow to the cylinders and valve boxes of steam engines and for other
similar purposes, the object of the invention being to supply a definite quantity of
lubricating material from time to time so long as the engine is at work
The body of the oil cup may be made either of metal or glass as may be
preferred
The base is made of metal and is in the form of a true facing It has a boss or
sleeve on the outside, beneath, and it is bored through the centre Through this 18
passed upwards a spindle which is made with a shoulder and upon this spindle
(inside the cup) are fitted two discs
The upper disc is fixed to the inside of the cup by means of lugs and sciews or
otherwise so that it cannot revolve and its lower side is faced to a true surlace
The lower disc 18 connected to the spindle by means of a pin and groove (or
otherwise) so that it revolves with the spindle, and it is faced on both sides so that
it revolves truly between the facing on the bottom of the cup and that on the
lower side of the upper disc, the spindle being fitted with a spring which presses
down the discs and keeps the facings in close contact
The bottom of the cup is perforated with a hole at a certain distance from the
centre, which communicates with the pipe or passage for conveying the oil or
lubricant to the cylinder or other place where it is required; and the upper disc
18 also perforated with a hole or holes at the same distance from the centre as,
but not opposite to the hole or holes in the base of the cup The lower or
intermediate disc is also perforated at the same distance from the centre with one
or more holes.
On the bottom of the spindle below the boss or sleeve is fixed a ratchet wheel
provided with a catch and the latter is connected to any convenient moving part

page_text: of the engine in such a manner that so long as the engine is at work the catch is
constantly turning the spindle round, and as each hole in the lower or intermediate
wheel (which revolves with it) comes under a hole in the upper disc, it becomes
filled with oil or other lubricant, and as it is revolving comes over a hole in the
base of the cup it discharges its contents into the cylinder, valve box, or other place
where it is required
I may here remark that in some cases I carry the spindle out at the top of the
oil cup instead of through the bottom or base as above described

I JOHN HOLT of Bankfield Cadaw Radcliffe in the County of Lancaster
Millwright do hereby declare the nature of my 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 employed for supplying
oil or tallow to the cylinder and valve boxes of steam engines and for other
similar purposes, the object of the invention being to supply a definite quantity of
lubricating material from time to time so long as the engine 18 at work
Such being the nature and object of my said invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect and in order that the same may be clearly understood
I have annexed hereunto a sheet of drawings illustrative thereof and have marked
the same with figures and letters of reference corresponding with those in the
following explanation thereof
Fig 1, on the drawing is a sectional elevation of my improved lubricator showing
a side view of the driving gear, and Fig 2, 18 a similar view showing a front
elevation of the same
The body a, a of the oil cup may be made of metal or glass as may be preferred
The base b, b is made of metal and is in the form of a true facing It has a boss
or sleeve c, c on the outside beneath, and it is bored through the centre Through
this is passed upwards a spindle d, which is made with a shoulder at e, e and
upon this spindle (inside the cup) are fitted two discs f, f and g, g
The upper
disc ff is fixed to the inside of the cup a, a by means of lugs and screws or
otherwise so that it cannot revolve, and its lower side is faced to a true suiface
Both of these discs are recessed into the bottom of the cup which thus supports
them and the spindle which passes through them
The lower disc g, g 18 connected to the spindle d, d by means of a pin and
groove (or otherwise) so that it revolves with the spindle, and it is faced on both
sides so that it revolves truly between the facing b, b on the bottom of the cup a, a
and that on the lower side of the upper disc f, f, the spindle being fitted with a
spring h, h which presses down the discs and keeps the facings in close contact
The bottom of the cup is perforated with a hole at a certain distance from the
centre which communicates with the pipe or passige k, k for conveying the oil or
lubricant to the cylinder or other place where it is required, and the upper disc f,f
is also perforated with a hole or holes at the same distance from the centre at
but not opposite to the hole or holes in the base of the cup
The lower or intermediate disc g, g is also perforated at the same distance from
the centre with one or more holes m, m
On the bottom of the spindle d, d. below the boss or sleeve c, c is fixed a mitie
wheel n, n driving a similar wheel on stud carrying a ratchet wheel o, o provided
with a catch p, p and the latter is connected to the radius or the valve rod or to
any convenient moving part of the engine in such a manner that so long as the
engine is at work, the catch p, p is constantly turning the spindle d, d round, and

page_text: as cach hole in the lower or intermediate wheel g, g (which revolves with it) comes
under a hole in the upper disc f. fit becomes filled with oil or other lubricant, and
as it is revolving comes over the hole 2, 2 in the base of the cup, it discharges its
contents into the cylinder, valve, box or other place where it is required
I may here remark that in some cases I carry the spindle out at the top of the
oil cup instead of through the bottom or base as above described
Having now particularly described and ascertained the nature of my sid
invention and in what manner the same is to be performed I declare that what
I claim 18
The improved lubricator constructed and operating substantially as hereinbefore
described and illustrated by the drawing annexed and especially I claim the
perforated disc revolving between two perforated facings and constantly carrying a
definite amount of oil from the perforation (or perforations) in the upper lacings
and delivering the same into the perforation (or perforations) in the lower facing
through which it passes to the cylinder or other part to be lubricated.
