Year: 1857

page_text: LETTERS PATENT to Joseph Miller, of Alpha Road, Regent's Park, in
the County of Middlesex, Engineer, for the Invention of "AN IMPROVED
ARRANGEMENT OF MARINE STEAM ENGINES."
PROVISIONAL SPECIFICATION left by the said Joseph Miller at the
Office of the Commissioners of Patents, with his Petition, on the
4th November 1857.
I, JOSEPH MILLER, of Alpha Road, Regent's Park, in the County of
Middlesex, Engineer, do hereby declare the nature of the said Invention for
"AN IMPROVED ARRANGEMENT OF MARINE STEAM ENGINES," to be as follows:-
My Invention consists in a new arrangement of the parts of marine steam
engines, in order to work the piston of the air-pump and feed, or cold water
or bilge pumps, by means of levers connected to and worked by links upon a
cross head on the head of the piston rod.
The cylinders are inclined, and to the cross head are connected two links; a
lever is connected to each link, and each lever is keyed or otherwise united to
a rocking shaft. From the under part of one end of this shaft another lever
descends, and is connected to the head of the piston rod of the air-pump. The
rocking shaft carries two other levers, which work the feed pumps, or cold
water or bilge pumps, as required.

+
My Invention consists in a new arrangement of the parts of, marine steam
engines, in order to work the piston of the air-pump and feed, or cold water
or bilge pumps, by means of levers connected to and worked by links upon. a
cross head on the head of a piston rod.
In Figure 1 of the annexed: Drawings, I shew, so much of one of a pair of
marine steam engines. as is necessary for the explanation of my Invention.
A is the inclined cylinder; B, the cross head;: to which are connected two
links C, one only being seen in the Drawing; D, D, are two levers shewn in
the detached view, Figure 2, connected at their upper ends to the links, and

page_text: at their lower ends they are keyed to a rocking shaft E; F is another lever,
keyed to the rocking shaft, and connected to the head of the piston rod G of
the air-pump, through the connecting rod H; I, I, are levers, also carried by
the rocking shaft, which work the feed pumps, or cold water or bilge pumps
K, K, as required.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim the particular
arrangement of the parts of marine steam engines, so far as regards the
working of the air-pump and feed, or cold water or bilge pumps, herein-before
described and represented in the Drawings annexed.
In witness whereof, I, the said Joseph Miller, have hereunto set my
hand and seal, this Third day of May, One thousand eight hundred
