Year: 1873

page_text: LETTERS PATENT to John Richardson, Engineer to the Firm of Robey
and Company, Perseverance Iron Works, Limited, Lincoln, for tho
Invention of "IMPROVEMENTS IN PORTABLE AND SEMI-PORTABLE ENGINES FOR
PROVISIONAL SPECIFICATION left by the said John Richardson at the
Office of the Commissioners of Patcuts, with his Petition, on the
16th December 1873.
I, JOHN RICHARDSON, Engineer to the Firm of Robcy and Company,
Perseverance Iron Works, Limited, Lincoln, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN PORTABLE AND SEMI-
PORTABLE ENGINES FOR WINDING, PUMPING, AND DRIVING PURPOSES," to be as
follows:-
Engines of the portable and semi-portable classes have hitherto been
made with the working parts secured to the upper part of the boiler by
bolts or otherwise, and the bearings for winding or pumping gear and
driving purposes generally either bolted to boiler, or attached to a frame-
work or masonry independent of the same, the whole arrangement being

page_text: exposed to several grave defects, viz., the boiler itself is subjected to
very severe strains due to the working of the engine and winding gear,
and the bearings of the machinery being so high above the ground lack
that rigidity which is so essential to the safe and economical working.
According to my present Invention the whole engine and winding
gear and parts connected are crected upon a bed plate lying on the
ground or a prepared foundation, which bed may or may not have a
prolongation at the one end forming an ash-pit fitted with damper doors
upon which the fire-box of boiler rests. The other end of the boiler may
or may not be carried by a support resting on the cylinder or other con-
venient part of engine.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Richardson in the Great Seal Patent Office
on the 16th June 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
RICHARDSON, Engineer to the Firm of Roboy and Company, Perseverance
Iron Works, Limited, Lincoln, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of December, in the
year of our Lord One thousand eight hundred and seventy-three, in
the thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said John Richardson, Her
special licence that I, the said John Richardson, my executors, adminis-
trators, and assigns, or such others as I, the said John Richardson, my
executors, administrators, and assigns, should at any time agree with
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, uso, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN PORTABLE AND SEMI-PORTABLE ENGINES FOR WINDING, PUMPING, AND DRIVING
PURPOSES," upon the condition (amongst others) that I, the said John
Richardson, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly
describe and ascertain the nature of the said Invention, and in what

page_text: manner the same was to be performed, and cause the same to be filed
in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said John Richardson, 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 thereof, reference being had to the Drawings here-
unto annexed, that is to say :-
This Invention has for object an improved arrangement of the working
parts of portable and semi-portable engines suitable for winding and
pumping and driving purposes, by which they are more compact and
more evenly balanced; likewise the structure is less liable to vibration,
the whole of the engine proper with the valves, slides, shafts, and wheels
being supported upon the base or bed plate, and with the starting,
reversing, and break levers within easy reach of the attendant from ono
side, whereby he can attend to the stoking as well as the working, as
will be clearly understood by the accompanying Drawings, Figures 1, 2,
and 3, which are respectively a side clevation, a plan, and an end view.
I construct my base plate A so that the portion L of it which is under
the cylinders B, B, serves as a tank for holding the feed water, and for
receiving the condensed water from the engine as well as the whole or
a portion of the exhaust steam, this being utilized for warming the feed
wator. The cylinders B, B, are arranged between stop lugs on the base
plate A, and are firmly bolted down upon it.
The cylinders are arranged with the valve box J between them, and
with the steam chest K above, into which a supplementary valve is fitted
to act as a stop valve, whose levers E, E¹, arc in connection with the
break lever G, and are acted upon separately a short time before the
break lever G is pressed upon by the foot of the attendant.
The main crank shaft M is supported upon bearings N, N, upon the
base plate, and the valves and connecting rods are worked direct, a band
or strap pulley P being upon one projecting end, and a pinion Q upon
the other, the equalization of motion being governed by the pinion
gearing into a wheel R upon a separate shaft supported partly in bearings
upon the base plate A, and partly upon a separate bearing and standard S.
This separate shaft has the fly and break wheel T upon it, also the
winding drums D, D, and pumping arms when such are required, a

page_text: sliding clutch U being upon the shaft to put the drums or arms into
action in the well-known manner, the clutch lever H being upon the
same side of the structure as the other levers before referred to.
I fit the boiler G upon the base plate A, so that the engine and its
working parts are beneath the barrel and well protected from injury,
and so that all of them can be conveniently got at for oiling and for
repairs when required, the boiler resting one end upon the cylinders B, B,
and the other or fire-box end direct upon the base plate A, whereby
the boiler is prevented taking the least strain cither from the working
of the engine or from any extraneous cause other than that of steam 1
pressure.
The steam chest K above the cylinders has the supplementary stop or
shut-off valve fitted and actuated, the lever E of which is connected to
the break lever, so that the steam can be shut off from the valve box
before the break lever is moved. F is the reversing lever and I the
clutch lever.
Having thus described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim,—
Firstly. The special combination and arrangement of the working
parts of engines and of appliances connected therewith when fitted upon
a base plate, in the manner set forth in or to portable or semi-portable
engines in which the boiler is arranged above and independent of the
base plate, as shown.
Secondly. Arranging and combining the winding and pumping gear
and levers connected therewith with the bed plate and working parts of 1
the engine, so that all the strain of such machinery shall be taken up by
the bed plate, and be so contained within and upon it as to make it
independent of the usual brickwork or masonry foundations, as set forth
and shown.
In witness whereof, I, the said John Richardson, have hereunto
set my hand and scal, this Eleventh day of June, One thousand
eight hundred and seventy-four

reference being had to the Drawings hereunto annexed, that is to say :-
This Invention has for object an improved arrangement of the working parts
of portable and semi-portable engines suitable for winding and pumping purposes,
by which they are more compact and more evenly balanced, likewise the structure
is less liable to vibration, the whole of the engine proper with the valves, slides,

side, whereby he can attend to the stoking as well as the working, as will bo
clearly understood by the accompanying Drawings, Figures 1, 2, and 3, which are
respectively a side elevation, a plan, and an end view.
I construct my base plate A so that the portion L of it which is under the cylin-
ders B, B, serves as a tank for holding the feed water and for receiving the con-
censed water from the engine, as well as the whole or a portion of the exhaust
