DRAINING STEAM ENGINE CYLINDERS
Year: 1884

page_text: I FREDERICK ALBERT SHARPE Opposite the Cornhill Lincoln in the County of
Lincolnshire Gas & Hot Water fitter, and WILLIAM WOOLLASON No 3, Great
Northern Terrace Lincoln in the County of Lincolnshire Engines Fitter do hereby
declare the nature of said invention for DRAINING STEAM ENGINE CYLINDERS, to
be as follows:-
The selfacting Steam Trap & Ejector is for Draining Steam Engine Cylinders
Steam Pipeing & any other form of Steam Chambers &°. The same Idea is also
used as, a Injector to Inject Oil to Lubricate Piston as well as air.
This invention is a selfacting Steam Trap & Ejector which are connected to
steam Engine Cylinders The action is as follows when the Main Slide Valve in
Steamchest of Engine opens the Steam will Hold the Valve (C) in the self acting
Steam Trap or Ejector when the main slide Valve in steamchest of Engine opens
the Exhaust, it will take away the Steam pressure off the Valve (C) in the self-
acting steam Trap or Ejector, The Valve (C) in selfacting Steam Trap or Ejector
is then raised by the Water that is forced from steam Engine Cylinder by the
Piston which the water passes through the ports (D) and (F) in the Selfacting
Steam Trap or Ejector by such action as Described above the water in Steam
Engine Cylinders is entirely let out without any escape of Steam, there are two
Selfacting Steam Traps or Ejectors connected to a steam Cylinder which Takes the
place of the ordinary Cylinder Cocks, The Selfacting Steam Trap or Ejector is
worked by the action of the Main Slide Valve in Steamchest of a Steam Engine.
Cylinder, Necessarily follows that the above described Invention dispenses of
labour turning off & on the Steam Engine Cylinder Cocks, no danger of bursting
Cylinder Covers off no Priming, no throwing Slide Valve in Steamchest off the
Valve face of Cylinders The destruction & wear & Tear of the Motion parts of
Engine is Entirely removed by using the above described Invention it will be a
Great economy to fuel.

FREDERICK ALBERT SHARPE Gas and Hotwater Fitter Opposite The Cornhill
Lincoln and WILLIAM WOOLLASON Engine Fitter Opposite The Cornhill Lincoln
in the County of Lincolnshire do hereby declare the nature of the invention for
DRAINING STEAM ENGINE CYLINDERS and in what manner the same is to be.
performed, to be particularly described and ascertained in and by the following.
statement:-
The Selfacting Steam Trap and Ejector is for draining Steam Engine Cylinders,
Steam Piping and any other form of Steam Chamber &º, The same idea is also
used as a Injector to inject Oil to Lubricate Piston, as well as air.
This Invention is a Selfacting Steam Trap and Ejector which are connected to
Steam Engine Cylinders The action is as follows, when the main Slide Valve in
Steam Chest of Engine opens, the Steam will hold down the valve (C) of Steam
Trap of Ejector.
.
When the main Slide Valve in the Steam chest of Engine opens the Exhaust it
will take away the steam pressure off the Valve (C) of the Steam Trap or Ejector;
The Valve (C) in the Steam Trap or Ejector is then raised by the water that is
forced from Steam Engine Cylinder by the Piston which water passes through the
Ports (D) and F in the Steam Trap or Ejector by such action as described above,
The water in Steam Engine Cylinder is entirely let out without any escape of
Steam, there are two Selfacting Steam Traps or Ejector connected to a Steam
Engine Cylinder which takes the place of the ordinary Cylinder Cock, The
Selfacting Steam Trap or Ejector is worked by the action of the main Slide Valve
in Steam Chest of a Steam Engine Cylinder.
Necessarily follows, that the above described Invention dispences of labour
turning off and on the Steam Engine Cylinder Cocks, No danger of bursting
Cylinder Covers off, No Priming, No throwing Slide, Valve in Steam Chest off the
Valve face of Cylinders.
The destruction and wear and Tear of the motion parts of the Engine is entirely
removed by useing the above described Invention it will be a great economy to fuel.

page_text: GENERAL REMARKS.
Letters on the Drawing filed with provisional specificational.
(A) is a Steam or a vent Pipe or a cored out Passage cast round Steam Cylinder
which is Connected to top of Steam Cylinder of Engine to avoid water left in
bottom of Steam Cylinder and also dry Steam, (B) is an Air Valve fixed on the
top of a Steam Engine Cylinder.
The use of the Air Valve is to let in the Air to destroy the Vacuum formed
before the Crank passes over the Centre of a high pressure Steam Engine, The
same time gives a spile vent to let out the water freely below.
(C). is the Steam or water Valve seated upon the in and out let Ports.
(D) is the in let from Steam Cylinder under the Valve (C) which passes over the
bar (E) that divides the Porte into the out let Port (F) which is connected to the
down Drain Pipes that are opened.
Having now particularly described and ascertained the Nature of our Invention
and in what manner the saine is to be performed we Declare that what we
Claim is;
The apparatus for draining Steam Engine Cylinders substantially as shown and
described
