IMPROVEMENTS IN LUBRICATORS
Year: 1884

page_text: I JOHN HOWARD KIDD, of Wrexham in the County of Denbigh Engineer, do
hereby declare the nature of said Invention for IMPROVEMENTS IN LUBRICATORS,
to be as follows :--
My invention consists in improvements in lubricators, the object of my Invention
being to improve and simplify the construction of lubricators in such a manner
that the working parts are not liable to get out of order and sufficient oil or other
lubricant is supplied automatically and with great economy.
To effect this I turn or otherwise form the reservoir or body of the lubricator of
metal or other material and of any required shape or size. In the stem of this
reservoir I form a hole of larger diameter at the upper part and tapering into the
smaller diameter of the lower part to form a valve seating for the underside of a
valve; the lower end of the valve spindle is fitted loosely into the hole of smaller
diameter and the upper end of the spindle is fitted loosely in and is guided by a
bush which forms a valve seating for the upper side of the valve and is screwed
into the larger hole which is tapped for its reception; the lift of the valve may be
adjusted when required by means of this screwed bush: holes are drilled round
the spindle in the flange of this bush to allow the lubricant to flow from the
reservoir into a space or chamber around the valve; the reservoir is provided with
a cap or cover and the stem is screwed into or otherwise secured to the cylinder
or other part of the engine to be lubricated.
The action of the lubricator is as follows:-The steam or other fluid under
pressure raises the valve spindle and lifts the valve off its lower seating and forces
it against the screwed bush thus cutting off the supply of lubricant from the
reservoir and allowing the lubricant stored in the chamber to flow into the cylinder
and to be forced into every part by the pressure of the fluid therein; on the
return stroke of the engine the valve spindle falls by gravitation (or assisted by a
spring if required) and cuts off the supply of lubricant to the cylinder and allows
the chamber to be again filled from the reservoir in readiness for the next stroke
of the engine.

page_text: I JOHN HOWARD KIDD, of Wrexham, in the County of Denbigh, Engineer, do
hereby declare the nature of said 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 :-
My invention consists in improvements in lubricators, the object of my Invention
being to improve and simplify the construction of lubricators in such a manner
that the working parts are not liable to get out of order and sufficient oil or other
lubricant is supplied automatically and with great economy.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Figure 1 is a sectional elevation, and Fig. 2 a plan of my improved lubricator
Figs. 3 and 4 show my improved lubricator fitted with a slightly modified formn of
valve and Fig. 5 is a view of my improved lubricator provided with an arrange-
ment for replenishing the reservoir while the engine is running.
In Figs. 1 and 2.- is the shell of the reservoir or body of the lubricator formed
preferably of metal in the stem a' of which is formed a hole 6 of larger diameter
at the upper part and tapering into the smaller diameter of the lower part so as to
form a valve seating b¹ for the underside of a double beat valve c; the lower end
of the valve spindle c' is fitted loosely in the smaller diameter of the hole b while
the upper part of the spindle c¹ is fitted loosely in and is guided by a flanged
bush & the underside of which forms a valve seating for the upper side of the
valve c. The bush & has an external screw thread and is screwed into the largest
diameter of the hole b which is tapped for its reception. The lift of the valve c
may be adjusted when required by means of this screwed bush d. There. are
holes drilled in the flange of the bush d to allow lubricant to flow from the
reservoir a into the space or chamber 6 around the valve c. The reservoir a is
provided with a cap or cover e and the stem a¹ is screwed into or otherwise secured
to the cylinder or other part of the engine to be lubricated. A light spiral spring f
is fitted on the valve spindle c¹ as shown to assist the action of the valve c.
The action of the lubricator is as follows:-The steam or other fluid under
pressure enters the hole band raises the spindle c³, lifts the valve c off its lower
seating b¹ and forces it against the upper seating d' thus closing the lower end of
the bush and cutting off the supply of lubricant from the reservoir a, and
allowing the small quantity of lubricant stored in the chamber 6 to flow around
the spindle c¹, down the hole b into the cylinder and to be forced into every part
by the pressure of the fluid therein. On the return stroke of the engine the
spring presses the valve c on to the seating b¹ and cuts off the supply of lubricant
to the cylinder and allows the chamber 6* to be again filled from the reservoir in
readiness for the next stroke of the engine.
In Figs. 3 and 4.-A ball valve g is shown in place of the double beat valve c
and the bush & has teeth cut on the periphery of its flange which teeth gear into
a worm ³ fixed on the end of a spindle which passes through the side of the

page_text: shell a so that by turning the small hand wheel d the height of the bush d and
the lift of the valve g may be slightly adjusted without having to open the
lubricator.
In Fig. 5.-The improved lubricator is shown provided with a different form of
cap or cover and an arrangement for replenishing the cup or reservoir a while the
engine is running.
In the top of the cap e is fitted a valve h opening inward and having a long
spindle h¹ the upper end of which is screwed or secured to a plate or disc i which
is fitted loosely in the upper part of the cap e and in which is a hole or opening i¹;
the lower end of the spindle h' extends down the cup a to within a short distance
above the spindle c¹. The plate or disc i is supported and the valve his held
against its seating e¹ by a spiral spring ; one end of which bears against the
plate and the other end against a plate or disk k in which are holes k¹.
To fill the cup or reservoir a press down the plate i thereby opening the valve h
until the extremity of the spindle h¹ presses upon the spindle c' and firmly holds
down the valve c on its seating b¹, the oil or other lubricant may then be poured
through the holes i¹and and so into the cup a. When sufficient lubricant has
been poured into the cup a and pressure is taken off the plate i the spring j causes
the parts to resume their normal positions.
Having now particularly described and ascertained the nature of my said
Invention and in what mannor the same is to be performed, I declare that what
I claim is
1.—The construction, combination, and arrangement of parts forming the im-
proved lubricator, substantially as and for the purposes herein described and as
illustrated by Figs. 1 and 2 and 3 and 4.
2.-The combination with the improved lubricator of the device or arrangement
for enabling the reservoir to be replenished with lubricant when the engine is
running, substantially in the manner herein described and as illustrated by Fig. 5.
