Brassfinisher do hereby declare the nature of our invention for IMPROVEMENTS IN
LUBRICATORS to be as follows:-
A hollow ram with internal Valve packed at both ends to be applied to
Hydraulics and high and low pressed steam worked by hand, lever, bell crank or
small Steam Cylinder connected with low pressure Cylinder, and condenser with
sight feeding, self closing drop Valve.
The Lubricator will have an open top with loose cover and perforated Strainer
inside of it to prevent all sediments from going through the Valves. The Strainer
will be loose inside so that it can be lifted out when required to clean. Attached to
the side of the Oil Cup there is a small drop and needle valve B for regulating the
supply, of Oil, below the needle valve there is a receiving cup with a check
valve C in the centre which catches the Oil from the drop valve,-the Needle Valve
touches the check valve. The Check Valve is worked by the motion of the Hollow
Ram. The Hollow Ram has a valve inserted at the end of it the will have 1
or stroke. On the inward stroke of the Ram it opens the Valve in the ram &
shuts the check valve. When check valve closes it lifts the small needle valve in
the drop valve & lets the Oil drop into the check valve below it. On the outward
stroke it shuts the valve in the Ram & opens the check valve. When the check
valve opens, the small needle valve shuts until the return stroke of Ram, by the
outward stroke of the Ram it forces the Oil that it receives on inward stroke
through holes in the centre of the Ram connected by Spiral Grove down into
steam chest or Cylinder. The ram can be worked by Steam Cylinder connected
to the top of low pressure Cylinder and vaccum from condenser on compound
engines or on any class of Engine by Bell Crank or Lever.
Dated this 19th day of August 1884.

Lubricator will have an open top with loose cover & perforated Strainer inside
of it to prevent all sediments from going thro the Valves. The Strainer will be
loose inside so that it can be lifted out when required to clean. Attached to the
.side of the Oil Cup there is a small drop and Needle Valve B for regulating the
supply of Oil, below the needle valve there is a receiving cup with a check valve C
in the centre which catches the Oil from the drop valve.
The Needle valve touches the Check valve. Check valve is worked by the motion
of the Hollow Ram. The hollow Ram has a valve inserted at the end of it will
have 2 or " stroke On the Inward stroke of the Ram it opens the valve in the
Ram & shuts the check valve. When check valve closes it lifts the small needle
valve in the drop valve and lets the Oil drop into the check valve below it. On
the outward stroke it shuts the valve in the Ram and opens the check valve. When
the check valve opens the small needle Valve shuts until the return stroke of Ram,
by the outward stroke of the Ram it forces the Oil that it receives on inward
stroke through holes in the centre of the Ram connected by spiral Groves down
into the Steam chest or Cylinder.
The Ram can be worked by steam Cylinder connected to the top of low pressure
Cylinder and vaccum from condenser on compound Engines or any class of Engine
by Bell crank or Lever.
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
1st The use and application of a Hollow Ram with internal valve in the
Lubrication of Steam, Gas, Air, Hydraulic and other motive Power Engines
as before described and illustrated in the drawings accepted with my
provisional specification.

page_text: a The construction and use of a self closing regulating drop valve as described
and illustrated in drawings accepted as before.
1 The use of a plain steam Cylinder for working the Lubricator on surface
condensing Engines by steam and vaccum from the condenser as herein
before described.
The construction and use of apparatus for forcing Oil or other lubricant into
the feed pipe, steam chest or any part or parts of Engines as herein before
described and illustrated in drawings accepted as before.
The combination and arrangement of an open reservoir A with perforated
strainer regulating drop valve B, check valve C, Hollow Ram E with
internal valve D and plain steam Cylinder for working same with steam
and vaccum as described and illustrated in the drawings accepted with the
provisional specification Number 1040.
