PROVISIONAL SPECIFICATION.
A Method for Readily Connecting and Disconnecting Steam and
Water Cylinders of Pumping Engines.
GEORGE MILLS, trading as George Mills & Co. Engineers, Globe Iron Works
Radcliffe near Manchester do hereby declare the nature of this invention to be as
follows:-
As at present arranged when the piston of the steam cylinder requires to be
examined or taken out then the trunk which acts as the front cylinder cover as well
as crank shaft bed has to be disconnected & removed, or the middle trunk together
with the water cylinder & connections have to be disconnected & removed. My
invention provides for the middle trunk which is fitted between the steam & water
cylinders & which acts not only as covers for the steam cylinder & water cylinder
but acts also as a binding connection & stay and is at present cast in one piece, is
to make this middle trunk in halves either longitudinal or cross ways & then bolt
them together or screw them with set screws, so that the trunk can be readily
taken in pieces & pistons examined & removed without removing the other parts of
engine as above indicated. I further provide for casting this trunk in three parts,
one part for steam cylinder cover, one part for water cylinder cover & one centre
piece for coupling these two together. I further provide in place of a trunk or
connecting piece to use & adopt bars or stays fastened to the steam & water
cylinders & these to act as coupling or binding bars.

COMPLETE SPECIFICATION.
A Method for Readily Connecting and Disconnecting Steam and
Water Cylinders of Pumping Engines.
GEORGE MILLS Engineer Globe Iron Works Radcliffe near Manchester do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
As at present arranged when the piston of the steam cylinder requires to be
examined or taken out then the trunk which acts as the front cylinder cover as well
as crank shaft bed has to be disconnected & removed or the middle trunk together
with the water cylinder & connections have to be disconnected & removed. My
invention provides for the middle trunk A which is fitted between the steam
cylinder B & water cylinder C & which acts not only as covers for the steam
cylinder B & water cylinders C but acts as a binding connection & stay.
Instead of casting this middle trunk in one piece my invention is to make this
middle trunk A four ways. One way being to make it in halves longitudinally as
shown on drawing D & bolt them together with bolts or set screws.
Another way
make it in halves cross ways & bolt them together with bolts or by set screws as
marked or shown on drawing J. Another way is to make the middle trunk in
three parts as shown on drawing E one part F to be attached to steam cylinder
cover, one part G being attached to water cylinder cover & one part H being the
centre piece for coupling F & G together being put together either with bolts or
set screws. Another way being in place of having the middle trunk A or similar
connecting piece I use bars or stays as shown on drawing I thereby acting as
couplings or binding rods between the steam cylinder B & water cylinder C.
