PROVISIONAL SPECIFICATION.
Improvements in Lubricators.
I, WILLIAM NAYLOR of 280 Pitsmoor Road, Sheffield, in the County of York
Mechanical Engineer, do hereby declare the nature of my said invention to
be as follows::
:-
My invention has for its object improvements in lubricators and refers
particularly to sight feed lubricators in which, as at present, the construction the
sight glass upon becoming broken allows the whole of the oil to escape while the
steam blows it in all directions and thus oil is wasted and very often damage is done.
By my improvements the breaking of the sight glass does not allow the oil to
escape the oil being automatically shut off immediately the glass is broken.
In carrying my invention into effect I form a cone mouth at each end of the
sight glass in which an indiarubber or other suitable ball is provided thus forming
a valve at each end of the sight glass. In case of the sight glass becoming broken
the pressure is released within the glass and thus the inward pressure causes the
balls to be forced into the cones and thus the valve is closed automatically. In
case of a lubricator with two or more sight glasses common to the same oil
chamber, it will be seen that with my improvement should one glass break the
remaining supplies would be unaffected. The body of the lubricator may be formed
of brass, copper, malleable cast iron or other such metal and may be provided with
any number of sight glasses common to the one oil chamber so as to give a
constant supply of oil to the cylinders slide bars and bearings of marine and other
engines.
I also introduce an india-rubber ring with a metal washer and nut for compressing
same so as to form a thoroughly tight joint to the valve closing the oil chamber.

COMPLETE SPECIFICATION.
Improvements in Lubricators.
I, WILLIAM NAYLOR, of 280 Pitsmoor Road, Sheffield, in the County of York,
Mechanical Engineer, do hereby declare the nature of my said invention 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 improvements in lubricators and refers

the pressure is released within the glass and thus the inward pressure causes the

of brass, copper, malleable cast iron, or other such metal and may be provided with
any number of sight glasses common to the one oil chamber so as to give a
constant supply of oil to the cylinders, slide bars, and bearings of marine and other
engines.
I also introduce an indiarubber ring with a metal washer and nut for compressing
same so as to form a thoroughly tight joint to the valve closing the oil chamber.
In order that my invention may be clearly understood and more easily carried
into practise I have appended hereunto a double sized sheet of drawings upon
which I have fully illustrated the nature of my said improvements.
Figure 1., is an elevation of one side of a lubricator partly shown in section.
Fi
figure 2., is an elevation of the front side of the lubricator.
Figure 3., is a plan of same.
In carrying my invention into effect I form a cone mouth A at each end of the
sight glass B the india-rubber or other suitable ball E being provided within the
cone so that in case of the glass B becoming broken the pressure within the glass
being relieved the balls E are forced into the cone mouths A by the inward pressure
and thus the valves are automatically closed and only the oil contained within the
glass B is, wasted. In the case of a lubricator with two or more sight glasses
common to the same oil chamber it will be seen that with my improvement should
one glass break the remaining supplies would be unaffected. The body of the
lubricator may be formed of any suitable metal and may be provided with a
separate condenser and with any number of sight glasses and I may have either a
single or double connection to each glass. To the valve closing the oil chamber I
provide the rubber ring F with a metal washer f¹ and nut f" for compressing same
thus forming a thoroughly tight joint at this point.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1st. The improvements in lubricators substantially as and for the purpose herein
set forth and shown upon the accompanying drawings.
2nd. In improvements in lubricators the sight feed having a cone mouth or
mouths A and ball or balls E substantially as and for the purpose herein set forth
and shown upon the accompanying drawings.
