PROVISIONAL SPECIFICATION.
Improvements in Steam Engines.
I, WEBSTER BARBER, of 44, Conway Street, Halifax, in the County of York,
Warehouseman, do hereby declare the nature of this invention to be as follows:
This invention relates to a new arrangement of steam engine wherein the cylinder
together with the piston rod are connected, to the fly wheel, and may form the boss of
the said fly wheel. The cylinder is provided at each side with studs or pivots so as
to form axis upon which it is made to revolve along with the fly wheel. On one side
of the cylinder port holes are made for the admission and exhaustion of steam.
An ordinary form of crank is connected to one of the studs of the revolving
cylinder from which crank a connecting rod is attached, the opposite end thereof being
connected to the outer end of the piston rod which imparts rotary motion to the
crank and consequently to the fly wheel. As the cylinder revolves it brings the ports
equally on both sides of the inlet port, intermittently, consequently the same quantity
of steam is admitted to both sides of the piston whereby the cylinder is evenly
balanced.
•
The governors consist of weights connected to vertical rods the opposite end forming
valves capable of working in slides, therefore when the engine is running at the normal
speed the slide-valve-governors are normal but should the engine run too fast the
increased velocity causes the slide valve rods to be thrown forward and close the valve
so as to lessen the steam inlet and thus reduce the speed of the engine but when the
engine becomes normal spiral springs around the said slide valve rods causes the valves
to be further opened so as to admit an increased quantity of steam to the cylinder.
By combining the cylinder with the fly-wheel the engine will be self contained
and more evenly balanced and will occupy less room or space.; there are also fewer
working parts. This construction of engine will also be less costly and a saving in
steam and coal will be effected.

I, WEBSTER BARBER, of 44, Conway Street, Halifax, in the County of York,
Warehouseinan, 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
This invention relates to a new arrangement of steam engine wherein the cylinder,
together with the piston rod are connected to the fly wheel, and may form the boss of
the said fly wheel. The cylinder is provided at each side with studs or pivots so, as
to form axes upon which it is made to revolve along with the fly wheel. On one side
of the cylinder, port holes are made for the admission and exhaustion of steam.

Fig. 1 is elevation of my improved steam engine having the cylinder and fly
wheel cast in one piece or secured together, and
Fig. 2 is front elevation of same.
Fig. 3 is elevation and Fig. 4 plan of my improved steam engine, having the fly
wheel journalled on a shaft eccentric of the pivots on which the cylinder turns as seen
in plan.
"
Fig. 5 illustrates four positions assumed by the ports in making one stroke of
the piston.
.
Fig. 8 is section of the cylinder and steam chest shewing the application of means
for governing the engine.
Fig. 9 is elevation partly in section of the cylinder and steam chest shewing the
water valve and outlets from the cylinder.
Fig. 10 shews side and part end elevation of cut off valve gear.
In Figs. 1 and 2, A represents the fly wheel, in the centre of which is cast or
otherwise secured a steam cylinder B, provided on each side with pivots a, b, working
in sockets in the parts c.
In the standards E is a shaft D eccentric with the axis of the cylinder and there
is mounted on said shaft D the lower end of a connecting rod F, the opposite
end of said rod being connected to the top of the piston rod G of the cylinder B,
so that as the cylinder causes the fly wheel to revolve, the said cylinder being
secured thereto is carried around with it, and the piston slided backward and
forward within the cylinder. d and e represent the port holes, the former being
for the admission of steam and the latter for exhaust.
Fig. 3 is an elevation and Fig. 4 plan of a slightly modified form of engine.
In this case the cylinder works upon pivots as previously described, but the upper
end of the piston rod G is connected to an arm H projecting from the face or
side of the fly wheel, which answers the purpose of the connecting rod F in
Figs. 1 and 2, so that the fly wheel revolves when the piston rod is moved
backwards and forwards in the cylinder which is effected through the admission
of steam in the inlet port d.
Fig. 5 illustrates four positions assumed by the cylinder during one stroke of
the piston.
Fig. 8 is cross section of cylinder and steam chest on a larger scale shewing
the governors which consist of vertical rods f having weights g at each outer end
and spiral springs as shewn on the drawings.
At the bottom of the rods f is a slide valve i which opens and closes the inlet
and exhaust ports d, e, the said slide valves together with their weighted rods being
operated by centrifugal force through the rotation of the cylinder.
The quicker the cylinder revolves, the weighted rods fly further from the centre
and admit less steam and when the rotary motion of the cylinder becomes slower
the ports are open wider and more steam admitted. The spiral springs act in
the opposite direction.
Fig. 9 shews an enlarged view of the cylinder together with the steam chest.
I also shew the means I employ for allowing the condensed steam or water to escape
just previously to starting the engine. In order to do this, I employ a pipe j, each
end of which enters the ends of the cylinder. This said pipe is connected to an
opening formed in the pivot b. In the end of the pivot is a spindle and valve l,
which valve is forced over small openings in disc m by the pressure of steam when
the engine is working, but in order to open the said valve, the engineer operates
the thumbscrew n and removes the valve from the openings in the disc m which
permits the water to escape when the engine is about to start.
be
Fig. 10 illustrates the cut off arrangement, which consists of a plate or disc M
forming the inner face of the steam chest. This disc is provided with openings N
through which the steam passes into the cylinder, but more or less steam may
admitted by operating hand wheel O which turns a screw P attached to a block R,
which block or valve R is drawn backward and forward so as to cover the inlet
valve N as and when required.

page_text: 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:-
Firstly. A steam engine where the cylinder is connected to the centre of the
fly wheel, such said cylinder rotating upon pivots and revolving with the fly wheel,.
as described and shewn in Figs. 1 and 2.
Secondly. A steam engine where the cylinder rotates upon pivots carried around.
by the fly wheel and where the upper end of the piston rod is connected to and.
operated by the said fly wheel as herein described and shewn in Figs. 3 and 4.
