"IMPROVEMENTS IN SELF-REGISTERING HYDRAULIC MOTORS AND THEIR APPLI-
CATION."
The object of my Invention is the production of a hydraulic motor of the
simplest description, and which having few parts is easily and cheaply made and
managed, and that will at the same time register the quantity of water passing
through it and be chiefly used where rectilinear movements only are required.
I attain this object in a design resembling somewhat the shape of a fork with a
couple of cross bars, the ends of the prongs forming the feet or the brackets, the
valve being placed in the centre where the prongs branch towards each side, and
the cylinder and slide or draw bar running through the prongs at right angles or
in any other convenient position, suitable bosses and ports being formed in the
prongs or arms of the fork to receive the cylinder, which consists in most cases of a
plain piece of brass or other metal tubing inserted from one end, and having its
ends expanded in the usual way or by some other convenient method, while the
cylinder ends, being of the usual description, are attached to the casting.
Parallel to the piston is the draw bar or slide bar to which the load is coupled,
and which is actuated by the piston rod and connected with the latter by means of
an ordinary bracket.
The valve is of the ordinary description, and worked by means of a lever coming
in contact with projections on the guide or draw bar, and on which projections

page_text: small indexed and adjustable cams are placed so that the length of the stroke may
be adjusted at sight.
Sometimes I use a tumbler arrangement instead of the latter.
I also provide the valve box with a suitable air vessel.
The inlet and outlot are on the sides of the valve box, and to one end of the
latter may be fitted a pressure gauge, and to the other a counting apparatus to
record the lengths through which the piston passes or the number of strokes and
to reduce it to gallons or other measurements, the quantity of water passing for
a given length or stroke being known. When this counting apparatus is applied
a pin is placed opposite to the valve, so that on removing the counting apparatus
the engine stops in consequence of the water escaping through the opening thus
left.
Another arrangement consists of a drum in a casing attached to the cylinder, and
revolving by the uncoiling of a chain or band attached to a reciprocating piston,
the projecting drum shaft carrying a pulley and actuating a counting apparatus,
the action being controlled by a three-way equilibrium cock or valve, made with a
double casing and peculiar arrangement of the ports, and serving as both in and
outlet and throttle valve. This valve is also applicable to other arrangements.
These motors may be used as organ blowers, for raising or lowering weights,
pulling bell hammers, alarums, punkahs, and for similar purposes, or they may be
used to produce a rotary motion. Among others I use it for winding up the weight
of a clock, the valve being opened by a pin fixed on one of the wheels.
These motors may be disposed in any position.

"IMPROVEMENTS IN SELF-REGISTERING HYDRAULIC MOTORS AND THEIR APPLI-
CATION."
The object of my Invention is the production of a hydraulic motor of simple
construction, and which having few parts is easily and cheaply made and managed,
and one that will at the same time register the quantity of water passing through
it, and be chiefly used where rectilinear movements only are required.
I attain this object in a design resembling somewhat the shape of a fork with a
couple of cross bars, the ends of the prongs or arms forming the feet or the
brackets, the valve being placed in the centre where the prongs or arms branch
towards each side, and the cylinder and also the slide or draw bar running through
the arms at right angles or in any other convenient position, suitable bosses and
ports being formed in the arms to receive the cylinder, which consists in most cases

page_text: of a plain piece of brass or other metal tubing inserted from one end, and having
its ends expanded in the usual way or by some other convenient method, while
the cylinder ends, being of the usual description, form part of or are bolted to the
casting.
Parallel to the piston is the draw bar or slide bar to which the load is coupled, and
which is actuated by the piston rod, and connected with the latter by means of an
ordinary bracket.
The valve is of the ordinary description, and worked by means of a lever coming
in contact with projections on the guide or draw bar, and on which projections
sinall indexed and adjustable cams are placed, so that the length of the stroke may
bo adjusted at sight.
I also provide the valve box with a suitable air vessel.
The inlet and outlet are on the sides, and to one end of the valve box or to the
top of the air vessel may be fitted a pressure gauge, and to the other end a counting
apparatus to record the lengths through which the piston passes, or the number of
strokes, and to reduce it to gallons or other measurements, the quantity of water
passing for a given length or stroke being known.
Another arrangement consists of a drum in a casing attached to the cylinder, and
revolving by the uncoiling of a chain, rope, or band attached to a reciprocating
piston, the projecting drum shaft carrying a pulley and actuating a counting
apparatus, the action being controlled by a three-way cock or by equilibrium
valves made with a double casing and peculiar arrangement of the ports, and
serving as both in and outlet and throttle valve. This valve is also applicable to
other arrangements
These motors may be used as organ blowers, for raising or lowering weights,
pulling bell hammers, alarums, punkahs, and for similar purposes, or they may be
used to produce a rotary motion. Among others I use it for winding up the weight
of a clock, the valve being opened by a pin fixed on one of the wheels.
These motors may be disposed in any position.
In order to more fully explain and illustrate my Invention I have delineated it
on the accompanying Drawings, which I now proceed to describe.
Similar letters denote corresponding parts.
Sheet I., Fig. 1, shows a view of a motor, and Fig. 2 a section of its body parallel
to that view; Fig. 3 is a cross section; Fig. 4, a side view in section of the
auxiliary valve; Fig. 5, a cross section of the valve box; and Fig. 6, part plan of
the same in section.
Sheet 2, Fig. 7, represents the arrangement of a drum in a casing attached to the
cylinder, actuated by a piston and chain or rope, as applied to hoists, and Figs. 8
and 9 illustrate the equilibrium valve in section and elevation and in end view.
Sheet 3 illustrates different applications of the motor.
Fig. 10 shews the motor working a direct-acting pump.
Fig. 11 is a perspective view of the motor with a pressure gauge on the air
vessel.
In Fig. 12 the motor is mounted on a base, and having a counter or registering
apparatus attached to one end of the valve box.
Fig. 13 represents the arrangement of a piston in a cylinder, with suitable valve
for winding up clocks automatically.
Fig. 14 shews the motor, fixed in an upright position, working a punkah.
Figs. 15 and 16 show two different modes of actuating bell hammers by the
motor.
C is the cylinder; P, the piston; R, the piston rod; D, the draw or slide bar
attached to the piston rod; p, p, are the ports; k, k, are the indexed and adjustable
cams to work the valve lever L; V is the valve box, and v the auxiliary valve
box; A is the air vessel.

page_text: In Fig. 7, 8, and 9, C is the cylinder; P¹, the piston; O, the chain, rope, or
other attachment; D', the drum in the casing B on the shaft S, carrying the pulley
or wheel W; E, E, are the equilibrium valves actuated by the lever L', on which
the cam F is pressed by springs, keeping the valve seats T in the desired positions
for effecting the ingress or egress of the water at the desired rate in such a manner
that both valves may be closed, or one may be wholly or partly open and the other
closed.
The various modes of coupling the motor illustrated on Sheet 3, and the manner
in which the same may be applied, require no further explanation, except Fig. 13,
which consists of an ordinary cylinder with a small common slide valvo, which is
opened by the action of the clock in the ordinary manner.
These various modes of applications may further be increased to all cases where
.rectilinear movement is required, and in some cases it will also be applicable to the
production of rotary motion.
The modes of application shewn may be largely modified, as also the form and
details shewn in the Drawings.
Having now particularly described and ascertained the nature of the said Inven-
tion, and in what manner the same is to be performed or carried out in practice,
I hereby declare that I do not confine myself to the exact forms and details shewn
in the Drawings, but I vary them according to the requirements of each individual
case, and I claim substantially and particularly,―
1. The construction of hydraulic motors with cast-iron arms, containing the ports
and having a cylinder of metal tubing inserted.
2. Actuating the valves by means of a lever from the slide bar.
3. Attaching registering or counting apparatus to the motor in such a manner
as to be self-registering, substantially as set forth.
4. The use of such motors for blowing organs, working pumps, punkahs, bell
hammers, and for other purposes requiring rectilinear or rotary movements.
5. The construction of double equilibrium valves worked by lovers and springs
and allowing both seats to be closed, or one wholly or partially open and the
other closed, substantially as set forth, and their use for motors, as shewn, and for
hydraulic purposes generally.
In witness whereof, I, the said William Henry Bailey, havo hereunto set my
hand and seal, this Twenty-fifth day of February, in the year of our Lord
One thousand eight hundred and seventy-nine.
