Improvements in Power Transmitting Apparatus.
I, MACARIUS PAÏDASSY, of Vassilieffsky, Ostrow, Great Perspective 68, St.
Petersburg, Russia, Inventor, do hereby declare the nature of this invention to
be as follows:-
My invention has for its object to provide an apparatus which I term a
telemotor." and which is designed to transmit reciprocating rotary motion to
any distance.
This apparatus is applicable for many purposes, as for instance
for controlling the angular movements of the rudders of boats or ships, for
closing and opening valves or doors at a distance, etc. etc. On boats the apparatus
can be applied more or less directly to the rudder head, through the medium of
levers, toothed segments, gear wheels etc., according to local conditions, whilst
on large ships and the like it is preferred to apply the apparatus to the valve of the
engine designed to move the rudder, whereby this latter can be controlled from
any desired place on the ship.
66
The application of my invention for such purposes as, for instance, controlling
a ship's rudder, is illustrated in the accompanying drawings wherein Figure 1
represents a front view of the motor engine of my apparatus; Fig. 2 is a
front view of the transmitting" engine of the same; Fig. 3 is a side view of
the transmitting" engine, and Fig. 4 represents a front view of a regulating"
engine attached to the transmitting engine.

My apparatus consists of two engines of almost the same construction A, A
and A', A¹ (Figs. 1 and 2) of which the first is the motor and the second the
power transmitter. Each of these engines consists of two cylinders pivotted at
their lower ends on hollow trunnions and provided with plunger pistons, the
upper ends of which are connected to opposite ends of a two armed lever or
swing beam B or B. On the axis of the swing beam B or B¹ is fixed a toothed
segment or arc T or T¹. In the motor engine the toothed arc is in gear with a
worm or screw C (Fig. 1) capable of being rotated by a hand wheel, whilst in the
transmitting engine the toothed segment meshes with a pinion D which receives
a rotary reciprocating motion and transmits it by means of any appropriate
gearing to the rudder or other part to be moved.
The cylinders of the motor and transmitting engines of my apparatus are
coupled together by tubes EE, -the right hand cylinder of the motor engine
to the left hand cylinder of the transmitting engine, and the left hand cylinder
of the motor engine to the right hand cylinder of the transmitting engine, the
end's of the tubes E E¹ being connected to the hollow trunnions of the respective
cylinders, whilst in the motor engine, the opposite ends of these trunnions are
connected with each other by means of a tube K provided with a cock (Figs. 1
and 3).
The tubes EE are connected by corresponding tubes E3 and. E provided
with cocks X and non-return valves Z (shewn in section in Fig. 1) to a vessel
or chamber G in which a constant pressure. is maintained. For this purpose
all the tubes E, E¹, E², E³ as also the vessel G are filled with water or other

page_text: .
fluid, and the vessel G is in communication with a steam boiler or other reservoir
of constant pressure.
When the apparatus is required to act, the cock on the tube K on the motor
engine must be closed. Then by turning the hand wheel of this engine towards
the right or left as the case may be, the worm C will rotate in the corresponding
direction, the toothed segment T, and consequently also the swing bar B which
latter causes one of the pistons of the motor engine to descend and the other to
rise.
In consequence of the way in which the cylinders of the motor and transmitting
engines are coupled together by the tubes EE as above described, the hydraulic
pressure generated by the descent of the plunger in the one cylinder of the motor
engine compels the corresponding piston of the transmitting engine to rise, thus
moving by means of the swing bar 13 of this engine, the toothed segment T¹
and consequently rotating the pinion D towards the right or left in strict con-
formity with the motion of the hand wheel of the motor engine. The axis of
the pinion D being connected to the rudder mechanism or other part to be
moved, it is evident that the motions of such part will be governed in strict
conformity with the movements of the hand wheel of the motor engine.
My apparatus has an additional controlling device in the form of a controlling
or regulating engine placed (as shown in Figure 3) behind the transmitting
engine and consisting of a single cylinder H communicating with the reservoir G
by a separate pipe 1'. The plunger piston of this engine carries three rods I, J
and L. The middle rod L serves as a guide for the piston and the two equally
inclined lateral rods I and J act on the opposite ends of a two-armed swing
bar M keyed on the same axis with the swing bar B (Fig. 3).
It is evident that, supposing the cock on the communication tube K between
the cylinders of the motor engine to be closed, the swing bar M (acting as one
with the bar B of the transmitting engine) will follow the movements of the
swing bar B of the motor engine when the latter is actuated by its hand wheel.
But when the cock on pipe K is opened and the two cylinders of the motor engine
are free to communicate with each other, the rotation of the hand wheel of this
engine will have no effect on the transmitting engine, and moreover, should
the swing bar B1 of the transmitting engine be in some inclined position, the
rods I and J attached to the piston of the cylinder H will so act on the swing
bar M as to compel the swing bar B1 to assume the horizontal position. Thus
the additional controlling engine affords an effective means of ensuring the
rudder (or other part) being brought to its middle position.
66
In ships I prefer to use as a reservoir of constant pressure (G) an ordinary
'steam trap" for condensed water, such as is always used where large steam
conduits exist. In this case the condensed water will compensate for any leakage
in the tubes E, E, E, E, thus avoiding the necessity of special pumps etc.

Improvements in Power Transmitting Apparatus.
I, MACARIUS PAÏDASSY, of Vassilieffsky, Ostrow, Great Perspective 68, St.
Petersburg, Russia, Inventor, 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:-
My invention has for its object to provide an apparatus which I term a

page_text: 66 telemotor and which is designed to transmit reciprocating rotary motion to
any distance. This apparatus is applicable for many purposes, as for instance
-for controlling the angular movements of the rudders of boats or ships, for
closing and opening valves or doors at a distance, etc., etc. On boats the apparatus
can be applied more or less directly to the rudder head, through the medium of
levers, toothed segments, gear wheels, etc., according to local conditions, whilst
on large ships and the like it is preferred to apply the apparatus to the valve of the
steering engine whereby this latter can be controlled from any desired place on
the ship.
The application of my invention for such purposes as, for instance, controlling
a ship's rudder, is illustrated in the drawings accompanying my Provisional
Specification wherein Figure 1 represents a front view of the motor engine'
"
"
of my apparatus. Figure 2 is a front view of the " transmitting" engine of the
same. Figure 3 is a side view of the "transmitting" engine, and Figure 4
represents a front view of an automatic quick return engine combined with the
transmitting" engine.
My apparatus comprises two hydraulically connected engines of almost the
same construction A A and A', A', (Figures 1 and 2) of which the first is the
motor and the second the power transmitter. Each of these engines consists of
two cylinders pivoted at their lower ends on hollow trunnions and provided with
plunger pistons, the upper ends of which are connected to opposite ends of a
two-armed lever or swing beam B or B. On the axis of the swing beam B or B
is fixed a toothed segment or are Tor T. In the motor engine the toothed arc
is in gear with a worm or screw C (Figure 1) capable of being rotated by a hand
wheel, whilst in the "transmitting" engine the toothed segment meshes with a
pinion which receives a rotary reciprocating motion and transmits it, by means
of any appropriate gearing, to the rudder or other part to be moved.
The cylinders of the motor engine are coupled with the corresponding cylinders
of the transmitting engine by tubes EE', the right-hand cylinder of the motor
engine to the left-hand cylinder of the transmitting engine, and the left hand
cylinder of the motor engine to the right-hand cylinder of the transmitting
engine, the ends of the tubes E E being connected to the hollow trunnions of
the respective cylinders, whilst in the motor engine the opposite ends of these
cylinder trunnions are connected with each other by means of a tube K provided
with a cock (Figures 1 and 3). The tubes EE are connected, by corresponding
tubes E and E provided with cocks X and non-return valves Z (shewn in section
in Figure 1), to a vessel or chamber G in which a constant pressure is maintained.
For this purpose all the tubes E, E', E2, E3, as also the vessel G, are filled with
water or other liquid and the vessel G is in communication with a steam boiler
or other reservoir of constant pressure.
When the apparatus is required to act, the cock on the tube K on the motor
engine must be closed. Then by turning the hand wheel of this engine towards
the right or left, as the case may be, the worm G will rotate, in the corresponding
direction, the toothed segment T, and consequently also the swing bar B, which
latter causes one of the pistons of the motor engine to move inwards and the other
to move outwards in the respective cylinders.
In consequence of the way in which the cylinders of the motor and transmitting
engines are coupled together by the tubes E E', as above described, the hydraulic
pressure generated by the inward movement of the plunger in the one cylinder
of the motor engine compels the corresponding piston of the transmitting engine
to move outwards, thus moving, by means of the swing bar B of this last
mentioned engine, the toothed segment T', and consequently rotating the pinion I
towards the right or left in strict conformity with the motion of the hand wheel
of the motor engine. The axis of the pinion D heing geared with the rudder or
other part to be moved, it is evident that the motions of such part will be
governed in strict conformity with the movements of the hand wheel of the
motor engine.

page_text: With the above mentioned engines there is combined an auxiliary quick return
engine placed (as shewn in Figure 3) behind the transmitting engine and
consisting of a single fixed cylinder H communicating with the reservoir G
by a separate pipe P. The plunger piston of this engine carries three rods I, J,
and L, of which the middle rod L serves as a guide for the piston and the two
equally-inclined lateral rods I and J act on the opposite ends of a two-armed
beam keyed on the same shaft with the swing bar B (Figure 3).
It is evident that, supposing the cock on the communication tube A between
the cylinders of the motor engine to be closed, the swing bar M (moving as one
with the bar B of the transmitting engine) will follow the movements of the
swing bar B of the motor engine when the latter is actuated. But when, by
the cock on pipe K being opened, the two cylinders of the notor engine are
free to communicate with each other, this engine will have no effect on the trans-
mitting engine, and should the swing bar B1 of the transmitting engine be in
an obliquely inclined position, the rods I and J attached to the piston of the
cylinder H will so act on the swing bar M as to compel the swing bar B¹ to
quickly assume the horizontal position. Thus the auxiliary engine affords an
effective means of quickly bringing the rudder (or other part) back to its middle
position, whilst the hand gear of the motor engine may be returned to its normal
mid-position at leisure.
65
In ships I prefer to use as a reservoir of constant pressure G, an ordinary
steam trap
"for condensed water, such as is always provided in connection
with large steam pipes. In this case the condensed water will compensate for
any leakage in the tubes E, E1, E2, E, thus avoiding the necessity for special
pumps, etc.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is-
66
1. Apparatus for transmitting motion, consisting of a "motor" engine and a
transmitting engine of substantially the same construction, in hydraulic
communication with each other in such a way that the position of the pistons
in one engine will always strictly correspond to the position of the pistons in
the other engine.
66
"
2. A motor engine consisting of two rocking cylinders with pistons or
plungers acting on opposite ends of a two-armed lever or swing bar secured on
the same axle with a toothed segment on which acts a worm capable of being
rotated by means of a hand wheel, the cylinders of this engine being provided
with hollow trunnions and communicating with each other by means of a tube
provided with a stop-cock as and for the purposes described.
3. A "transmitting" engine consisting of two rocking cylinders with pistons
or plungers acting on opposite ends of a two-armed lever or swing bar secured on
the same axle with a toothed segment which gears with a pinion adapted to
transmit the movements of the toothed segment to rudder or other movable
mechanism as and for the purposes described.
4. In the herein described apparatus the combination with the transmitting
engine as herein specified, of an auxiliary engine consisting of a single cylinder
and a piston adapted to so act on the opposite ends of a two-armed lever or
swing bar fixed on the same shaft with the lever of the transmitting engine so
as to bring the latter back to normal or mid position when the cylinders of the
motor engine are put in direct communication substantially as and for the
purpose set forth.
