Improvements in Reciprocating Water Motors.
I, WILLIAM THOMAS SUGG, of Vincent Works, Regency Street, Westminster,
S.W., Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a simple and effective apparatus,
by means of which fluids, such as coal gas or air, may be forced into a flexible
or equivalent receiver, preparatory to being used for any purpose in the arts.
The invention specially relates to the motor for operating the purely forcing
mechanism, and chiefly to such motors when driven by water power.
In carrying out this invention, a cylinder is provided having a motor piston
mounted on a rod which projects through both ends of the cylinder, so that the
effective area of the piston will be practically the same on both sides.
One end of this rod is free, and the other is connected to any convenient form
of forcing mechanism.
Each end of the cylinder is connected by ports or passages with a valve case in
which is mounted a floating valve, and also an auxiliary valve operated by a
tappet on the piston rod. This valve case may be said to include an inlet
chamber in connection with the water supply, an outlet chamber for the exhaust,
& with which both ports or passages connect, and what may be termed a pressure
chamber.
The inlet chamber connects directly with one end of the cylinder and, through
the floating valve, which is hollow, with the other end of the cylinder.
The floating valve consists of a piston with a hollow stem having lateral
openings just below the piston.
Beyond these openings, is a second piston, disc, or washer, of the same diameter
as the main piston, and at the other end of the hollow stem is another piston,
disc, or washer, of less diameter than the main piston.
This floating valve is arranged in the case so that it will shut off and open the
several ports or passages as desired.
The auxiliary piston is contained in the pressure chamber below the floating
piston, and is operated by a tappet on the motor piston, striking stops on the
piston rod.
This piston has ports or passages through it for the purpose to be presently
explained.
The inlet chamber is in connection with the pressure chamber above the
auxiliary piston, and the outlet chamber is connected with the pressure chamber
below the piston.
The working is as follows:-Suppose the motor piston has reached the end of
its upward stroke, the auxiliary piston will also have been raised, and will have
closed the pressure inlet. It will also have opened the outlet to the exhaust
below the piston.
The pressure being removed from the underside of the floating piston this
latter will, partly by its own weight, and partly by the pressure of the inlet on
the top, drop, and open the inlet port to the top of the cylinder, the water below

page_text: the floating piston escaping through the auxiliary valve and the exhaust con-
nection below the piston to the outlet.
The pressure of the water now acts on the top of the motor piston, and pushes
it down. As it reaches the end of its downward stroke, the tappet operates
the auxiliary valve, and lowers it, by which operation the outlet is closed,
and the inlet to the pressure chamber is opened. The pressure of the water
now acts on the larger area of the floating valve, and raises the valve, so that
the inlet to the top of the motor cylinder is closed. The exhaust is opened, and
the inlet to the bottom of the cylinder is also opened, the motor medium passing
down the hollow stem of the valve to the inlet port, and to the underside of
the piston. As the piston reaches the end of its upward stroke, the auxiliary
valve is again operated, the pressure is shut off, and the floating valve drops,
thus again changing the direction of the motor medium.
These operations are repeated so long as the water continues to be supplied
to the motor..
The supply of water will however be regulated by suitable means, actuated by
the movement of the gas receiver, under the influence of the pressure of the
gas being supplied thereto by the motor.

Improvements in Reciprocating Water Motors.
I, WILLIAM THOMAS SUGG, of Vincent Works, Regency Street, Westminster,
S.W., 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:-
The object of this invention is to provide simple and effective apparatus for
operating forcing or compressing mechanism by means of which fluids, such as
coal-gas or air, may be forced into a flexible or equivalent receiver, preparatory
to being used for any purpose in the arts.
The invention especially relates to the motor for operating the forcing or com-
pressing mechanism proper, of any convenient construction or character.
In the accompanying drawing I have shown this motor in vertical section,
applied to a compressing apparatus, which, however, forms no part of the pre-
sent invention.
The motor, which may be driven by water power, consists of a cylinder a, pro-
vided with a motor piston b, mounted on a rod c, which projects through both
ends of the cylinder, so that the effective area of the piston will be practically
the same on both sides.
One end of this rod e is free, and the other end is connected to the forcing
mechanism.
Each end of the cylinder is connected by ports or passages e, f, with a valve
case g, which contains a floating valve h, and also an auxiliary valve . This
valve consists of a short cylinder or ring, conveniently secured to a rod 7, and
is operated by a tappet j, on the piston rod c, striking against stops on the rod 7.
The valve case g may be said to include an inlet chamber m, in connection with
the water supply, an outlet chamber o for the exhaust, and with which both
ports or passages e, f, connect, a supplemental chamber m¹, and what may be
termed a pressure chamber p.

page_text: The inlet chamber m connects directly with one end of the cylinder a by the
port e, and with the other end of the cylinder a, through the stem of the floating
valve (which is hollow), and the supplemental inlet chamber m', by the port f.
The floating valve consists of a hollow stem, carrying a piston, disc, or
washer, h, 8, at opposite ends, and a third piston, disc, or washer, h³, about
midway between the other two. Below this middle disc h³, the stem is pro-
vided with lateral openings h, connecting with the supplemental inlet
chamber m', which is thus, in effect, formed by the two lower discs or
pistons, h The top piston or disc ¹ is of slightly less diameter than the
other two discs.
The floating valve is arranged in the case g, so that it will shut off and open
the ports or passages e, f, to the pressure and exhaust, as required.
The auxiliary valve i is contained in the pressure chamber p, below the bottom
piston or disc 2, of the floating valve h, and is operated by a tappet j on the
motor piston rod e, striking stops on the rod 7, as before explained.
The valve covers ports or passages in the case g, connected with the pipes q
and r, for a purpose to be presently explained.
The inlet chamber m is in connection with the upper part of the pressure
chamber 2, through the hollow stem of the floating valve h, the supplemental
inlet chamber m¹, and the pipe q, and the outlet or exhaust chamber o is con-
nected with the pressure chamber 7, below the piston, by the pipe r.
The working is as follows:-
Suppose the motor piston 6 has reached the end of its upward stroke, the
auxiliary valve i will also have been raised by the tappet j, on the piston rod o
striking one of the stops on the valve rod 7, and will have closed the port to the
pipe q
It will also have opened the port below the piston 2 of the floating valve h
to the exhaust o, through the pipe r.
The pressure being thus removed from the underside of the floating valve h,
this latter will drop, partly by its own weight, and partly by the pressure at the
inlet m on the disc ', and open the inlet port e,-to the top of the cylinder a,—
the water below the floating valve h passing through the cylinder of the
auxiliary valve i, and, by the exhaust connection r, below the valve i, to the
outlet o.
The pressure of the water now acts on the top of the motor piston b, and
pushes it down. As it reaches the end of its downward stroke, the tappet j,
on the rod c, operates the auxiliary valve i, in the opposite direction, and lowers
it, by which operation the outlet port to r is closed, and the inlet port to g and
the pressure chamber is opened. The pressure of the water now operates
on the larger area 2 of the floating valve h, and raises the valve, so that the
port e to the top of the motor cylinder is closed against the supply of water,
but is opened to the exhaust o. The inlet f to the bottom of the cylinder a
is at the same time opened to the water supply, the motor medium passing down
the hollow stem of the valve h, out through the openings h, into the supple-
mental inlet chamber m¹, and thence, through the inlet port f, to the cylinder a
at the under-side of the piston b. As the piston reaches the end of its upward
stroke, the auxiliary valve i is again operated. the pressure is shut off, and
exhaust opened, so that the floating valve h drops, thus again changing the
direction of the motor piston b.
These operations are repeated so long as the water continues to be supplied
to the motor.
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:-
-:
1. A water motor for various uses in the arts, constructed, arranged, and
operated, as herein shown and described,

page_text: 2. In a water motor, the means for changing the direction of the motor piston,
consisting of a cylindrical valve box, connected with opposite ends of the motor
cylinder, and containing at one end a main inlet chamber in direct connection
with one end of the cylinder, and at the other end a pressure chamber, a floating
valve separating the two chambers; the floating valve being composed of a
hollow stem, with a piston at each end, and another about the middle of its
length, the said three pistons, with the cylindrical valve box, forming (1) an
outlet chamber common to both ends of the cylinders, and (2) a supplemental
inlet chamber for the other end of the cylinder, and with which the main inlet
connects through holes in the hollow stem of the floating valve.-an auxiliary
valve in the pressure chamber suitably operated, and ports or passages connect-
ing the pressure chamber with the outlet chamber and the supplemental inlet
chamber, to be opened and closed by the auxiliary valve, as shown and described.
