Year: 1885

page_text: I WILLIAM DODSHON of 129 Gloucester Road N.W. London in the County of
Middlesex Jeweller do hereby declare the nature of my invention for IMPROVE-
MENTS IN APPARATUS FOR THE PREVENTION OR RELIEF OF SEA-SICKNESS to be as
follows:-
This invention relates to improvements in and connected with apparatus for the.
prevention of sea-sickness in respect of which an application for a patent by
complete specification was accepted on August 21, 1885 and dated Dec. 2, 1884,
No. 15824.
According to the said application a resisting surface placed in the water some
distance below the bottom of the ship for the purpose of causing an electric
apparatus to work according to the rise and fall of the ship, this resisting surface
is exposed to the constant pressure of the water as the ship is propelled through
the water, the object of part of this invention is to protect the resisting surface
from this pressure by placing it in or enclosing it in a case or shield preferably in
the form of a cigar, fish, or similar shape, with openings top and bottom to allow
the water to act on the resisting surface when the ship rises and falls.
The resisting surface may be of any suitable form, it may work on a hinge or
joint or be connected or supported in any other suitable way.
The second part of this invention relates to a means by which the rise and fall
of the saloon and other apparatus may be regulated in the steam winding engine
system described in the before mentioned application, by this plan a large disk
which is made to revolve by a train of wheels, the disk gives motion to a small
wheel which is pressed against its face, the edge of the small wheel may be covered
with india-rubber, the spindle of the small wheel is connected to the stopping
valve.
The regulation is effected by moving the small wheel to or from the centre of
the disk by means of a screw and nut.
The other part of this invention relates to a means of working a saloon or seat,
and other apparatus by means of hydraulic power instead of a steam winding
engine as described in the invention refered to.
The hydraulic machinery is of the type used for the steering of ships with some
modifications

page_text: A general discription may be given as follows:-A steam pump supplies a
constant fluid pressure by a pipe to the working cylinder placed near the saloon
and other apparatus that is made to rise and fall, it is not necessary to use an
accumulator, but one may be used if thought desirable, as it will render the action
of the pump and engine more uniform and steady, an air chamber can be placed in
any convenient place on the water pipe, a relief valve is fixed near the pump.
The water or other liquid under constant pressure is conveyed to one side of the
piston of the working cylinder, on the other side of the piston the water is open
alternately to the exhaust and constant pressure, the area of the piston is larger
on this side on account of space taken up by the hollow piston rod on the other
side of piston-therefore when the valve opens the port that allows the constant
pressure to act on the large piston area the pressure on the small piston area is
overcome and motion is given to the saloon and other apparatus, and they are
made to rise. When the valve is reversed the water on the piston of large area
is open to the exhaust and the piston of small area is exposed to the constant
pressure therefore the movement due to this last condition will have less power,
which is just what is wanted for the falling motion of the saloon and other
apparatus as they have a tendencey to fall of their own accord or rather will do so.
The smaller area of piston is so proportioned to give just sufficient power to
overcome the friction and move the apparatus at the desired speed. I may use
single acting pistons or rams.
.
Motion is given to the saloon and other apparatus by pulley wheels and chains
connected with the pistons or rams in the usual way one stroke of the piston
effecting a rise and the back stroke the fall of the apparatus.
The falling is also regulated by a stop-cock placed in the exhaust passages by
which the escape of the water can be controlled.
The starting, stopping and reversing valve is all in one and is of a similar
formation to the valve arrangement described for the steam winding engine before
refered to, it is a double valve with perforated plate or plate with openings
corresponding to the ports on the valve face, with a box valve moving on top of it.
The cut off is caused by the action of a small hydraulic cylinder which works
the box or cut off valve automatically.
The magnets. work the plate valve in the same way as described for the before
said steam winding engine, the speed of the cut off being regulated by a stop-cock
that opens or contracts the passages that communicate with the large area side of
piston of the small cylinder and the exhaust and constant pressure alternately.
1 may use a small hydraulic or steam cylinder to work the starting or plate
valve, the piston of the small cylinder is connected to the spindle of the plate
valve.
The slide valve of the small steam or hydraulic cylinder, or engine, is worked by
the magnets, by this means I can use much smaller magnets.

page_text: Improvements in Apparatus for the Prevention or Relief of
Sea-sickness.
I WILLIAM DODSHON of 129 Gloucester Road London in the County of
Middlesex Jeweller 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 improvements in, and connected with apparatus for the
prevention or relief of sea-sickness, in respect of which Letters Patent have been
granted me, dated 2nd December 1884 N° 15824 According to the said former
patent an electric apparatus is used for the purpose of controlling the valves of a
winding engine by which seats, platforms, cabins, saloons, berths or hammocks
may be controlled so that they move in the opposite way to the rising and falling
of the ship caused by the rising and falling of the waves, and thereby be made
nearly notionless as regards up and down motion.
I may speak of the rising and falling of the saloon or other apparatus, but I
wish it to be distinctly understood that I mean rising and falling in relation to
the ship.
Part of the apparatus consists of a resistance surface placed in the water some
distance below the bottom of the ship for the purpose of causing the electric
apparatus to work in unison with the rising and falling of the ship, This resisting
surface is exposed to the constant pressure of the water as the ship is propelled
through the water the object of part of this invention is to protect the resisting
surface or body from this pressure, by placing it in or enclosing it in a metal case
or shield of the form of a cigar, fish, or similar shape I prefer to make it of copper
This case is shewn in section in Fig. 1 and 3 sheet 1 of the accompanying sheets of
drawings. The same reference numbers indicate corresponding parts in all the
figures on sheet 1 and 2.
Fig. 2 shews the outside of the case. This case is connected to the tube 9d, that
goes down into the sea some distance below the bottom of the ship by a fork 7ª
Fig. 3 sheet 1, and turns on the pins 7b, 7° which are placed nearer the head than
the tail so that it may keep itself true or parallel with the line of motion of the
ship, this fork is connected to the tube 8 which fits in the tube 9d, the tube 8
passes a little way through the case and has on this part a piece of metal in the
form of a segment of a circle 7, that fills the opening at whatever angle the case
may be, the movement of the case round the pins 7b, 7°, is limited by the sides of
the opening striking against the tube 8; the case is balanced by the weights 4
and 5.
.
The weight 4 is to balance the tail and the weight 5 is to keep the centre of
gravity of the case below the pins on which it turns so that it may keep
horizontal.
The tube 8 can turn a little in the tube 9ª and allows the case to turn in a
horizontal plane, this movement is limited, by a piece 9, that forins a stop and it
will be seen that two half caps 9, and 9' have rims that fit under this piece and

page_text: hold the tube 8 in position. The extent of the movement depends on the size of
the openings 9° and 9ª Fig. 10 which is a section through x, y. The half cap 9° is
partly broken away in Fig. 1. so that this part may be plainly seen.
2 is the resisting surface or body preferably oval in plan which is loaded with
lead or mercury 2³, the centre of gravity being below the hinge or joint 2b by
which it is connected to the rod 12 so that it may always remain horizontal, the
holes b. c, d, e f, g and others should be about half an inch in diameter they may
be in a cluster of ten or more these allow the water to press on the resisting body 2
when the ship rises or falls, to the rod 12 is attached the line or wire 12° that
passes up the tube 9d and communicates the pressure produced on the resisting
body 2 to the electrical, apparatus on board the ship, The rod 12 is kept central
with the tube by six rollers, two are shown at 8ª and 9° Fig. 1, Fig. 4 shews a
plan of the top set of rollers, the resisting. body 2 is kept from turning by the
small roller 8b that slides between plate guides the two studs Se and 8d prevent
the resisting body 2 from getting too much out of position even when the line is
detached, the working movement of the resisting body should be between the stops
and not touching them. The case 6 surrounds the resisting body and is attached
to the removable portion 10% of the fish shaped case, it must not fit close, and
serves to prevent the water escaping past the resisting surface too readily.
The bar 9 forms part of the tube 98, if thought desirable this may be bent down
at the ends and connected to a frame that forms a guard round the case 10. To
the bar the four cables or wire ropes are attached that hold the fish shaped case in
position, they are shewn by the dotted lines which shews their direction as well.
One of those connected to the end 9° and one of those connected to the end 9b are
made secure to one side of the ship and the other two to the other side of the ship,
these cables may be made tight by means of screw rods in the usual way.
This part of the apparatus should be arranged so that the fish shaped case is
under the middle of the saloon or other apparatus. or nearly so.
The fish shaped case and other parts herein explained are to be used instead of
the plan in the herein before mentioned patent for either the winding engine
system or the hydraulic system to be explained hereinafter.
A round case or shield and resisting body may be used, the case should be
heavily weighted at the bottom to keep it in its right position that is to say with
the holes top and bottom, the resisting body should have an area of about two
square feet, but the necessary size will vary according to the depth below the ship
at which it is fixed if at a short distance from the ship it must be larger than it
would require to be at greater distance.
Fig. 9 shews a method of holding the tube, that conveys the line, in position
against the keel and bottom of the ship, 81 is a section of the keel and part of the
body of a ship, 84 is a strong forging into which the keel fits, this has an
adjustable block 85, 82 shews a section of a bar which forms part of the forging
and goes along the keel for some distance on either side and is furnished at each end
with a fork that embraces the keel in the same way as the part of the forging 84,
83 is a cable or wire rope or other rope by which this part of the apparatus is
made secure on the deck or at the side. When it can be conveintly done I
should prefer to have the tube straight through the bottom of the ship to aviod
the angles and the necessary rocking levers one of which is shewn at 84ª four
other cables are shewn by dotted lines that take the same direction as those
attached to the bar 9.
The second part of. this invention relates to a means by which the rise and fall
of the saloon and other apparatus may be regulated in the steam winding engine
system described in the before mentioned patent, by this plan a large disk is made
to revolve by a train of wheels, the disk gives motion to a small wheel which is
pressed against its face. The edge of the small wheel may be covered with india-
rubber, the spindle of the small wheel is connected to the stopping valve. The
regulation is effected by moving the small wheel to or from the centre of the disk
by means of a screw and nut.

page_text: The other part of this invention relates to a means of working saloons, seats,
platforms, berths, floors, cabins, and hammocks by means of hydraulic power
instead of a steam winding engine as described in the invention herein. before
refered to.
The hydraulic machinery is of the type use for the steering of ships, with some
modifications, or as regards the engine and pumping part after the general con-
struction of a steam fire engine modified so as to produce the pressure that the
water or other liquid is to be worked at, which may be that pressure that is usually
found most advantageous in working lifts and cranes.
The following is a description of the hydraulic apparatus.
A steam pump supplies a constant fluid pressure by a pipe 36 Fig. 2, 3 and 5
sheet 2, to the working cylinder 25, Fig. 5 and 8 sheet 1, fixed in any convenient
position near the saloon or other apparatus, it is not necessary to use an
accumlator, but one may be used if thought desirable, as it may render the action
of the pump and engine more uniform and steady; an air chamber is to be placed
in any convenient place on the water pipe near the pump, a spring relief valve 37
is fixed near the pump.
The water or other liquid under constant pressure is conveyed by the pipe 36 to
the small area side of the piston 21 of the working cylinder 25. This side of the
piston has a smaller area than the other on account of the space, taken up by the
piston rod 20. The smaller area of piston is so proportioned as to give just
sufficient power to overcome the friction and move the apparatus at the desired
speed.
When the valve 31 Fig. 7 sheet 2 opens the port 34° that allows the pressure to
act on the large piston area by the pipe 34, the pressure on the small piston area
is overcome and the saloon, or other apparatus, is made to rise in relation to the
ship, or in other words to move in the reverse way to the motion of the ship.
There may be a valve on the pipe 34 to start and stop the apparatus. When the
valve is reversed the water on the large area side of the piston is open to the
exhaust and the small area side of piston is exposed to the constant pressure
therefore the piston is driven the reverse way; from the above it will be seen that
the larger area side of the piston is open alternately to the exhaust and pressure
by the action of the valves.
The object of having the piston double acting is to have the speed of the falling
of the saloon or other apparatus under control because the rate of motion of the
rising and falling of a small wave is different to that of a large wave.
The pipe 36 is furnished at any convenient part with a three way cock that in
one position cuts off the water under pressure from the small area side of the
piston 21 and at the same time opens that side of the piston to the atmosphere, by
this means the piston or rains becomes single acting, in the other position the
communication is as first described.
The valve case and valves are shewn in elevation Fig. 2 sheet 2. Fig. 3 is an end
elevation Fig. 5 is a plan of the valve face with part broken away, shewing the
relief valve and exhaust passages in section. Fig. 7 is a section, Fig. 9 is a section
through A. B. Fig. 2 shewing the valves and connections.
The starting, stopping and reversing valve is all in one and is of a similar
formation to the valve arrangement described for the steam winding engine
herein before refered to, it is a double valve with perforated plate 31 Fig. 7
sheet 2, or plate with openings. corresponding to the port 34 and 35b on the valve
face. This plate is controlled by the piston 29° working in a small hydraulic
cylinder the rod or spindle 29 that drives this part of the valve is connected to the
piston as shewn.
The valve 33 is supported by a spring 33° and is also provided with a balancing
piston 33
30 is a box valve moving on the top of the plate 31 and balanced by,
the piston 27 connected to the valve by links 27%. The cut off is automatically
effected, by the pistón 28* working in a small hydraulic cylinder the piston rod of

page_text: which drives the box or cut off valve 30 by means of the block 28° Fig: 7, and 9,
the speed of the cut off being regulated by a stop cock or valve 54 that opens or
contracts the passages 34b shewn in dotted lines in Figs. 2, 3, 5. 7 sheet 2, this
passage communicates with the large area side of piston 28" of the small cylinder
and the exhaust and constant pressure alternately according to the position of the
valves 30 and 31..
I should prefer to make the stroke of the valves 30 and 31 longer than is shewn
in the drawing this may be done by making the ports 34°, and 35 and 34° wider
and of course the valves 30 and 31 must be longer in proportion and the two
openings in the valve 31 wider apart.
"
'
I may here say that the two cylinders and pistons that actuate the valves work
on the same principle as the hydraulic ram 25 Fig. 5 sheet 1. The areas of the
pistons are so proportioned that the part of the piston rods that pass out of the
stuffing boxes or leathers are of a sectional area equal to one half of the area of
the large area side of the pistons, the small area sides of these pistons are exposed
to the constant pressure of the water in the valve case Fig. 27 sheet 2.
The electro magnets work the starting or plate valve 31 by first acting on the
valve 33 of the auxiliary piston and cylinder; they may work the valve directly
as in the before said steam winding engine system.
The electro magnets must be powerful enough to work the valve, the current
may be supplied from a dynamo or from a secondary battery.
If the steam pump has a fly wheel the dynamo or electric generator may be
driven from a pulley on the fly wheel shaft.
When the piston 29" moves the plate valve 31 the plate valve tends to carry the
box valve with it by friction, for the purpose of preventing this I use a break
Fig. 4 and 2 which embraces the rod 28. The friction can be regulated by the
handle and screw 56, the blocks 28, 28 may be hard wood or metal.
Fig. 6 shews another method which may be used for the same purpose the
piston 28 works in a longer cylinder than is shewn in Fig. 7, and the piston rod is
of the form shewn in Fig. 11, it will be seen that the end that passes out of the
leathers or stuffing boxes is round, the middle portion is twisted, a square rod
twisted, the part connected to the piston is square, the square portion fits and
slides in a square hole in a fixed block 50, this prevents the rod from turning, the
twisted part works in a long nut 41. This nut is screwed on the outside and
works in a nut 51* this nut engages with the box valve and has guide blocks 52
that prevent it from turning. The action is this, when the piston 28 and rod'
moves the long nut 41 turns, in doing so the nut or block 51 is caused to move
along and work the valve.
Fig. 12 is an end view of the valve and connections, part of the links are
broken away.
Motion is given to the saloon or other apparatus by pulley wheels and chains
connected with the pistons or rams in the usual way as shewn in Fig. 5 sheet 1.
If thought desirable one of the hydraulic cylinders may be fitted at each end of the
saloon, or more than one may be used at the one end.
Fig. 6 shews-four of the pulleys that are mounted on a cross head on the ram 20
there are also on the other end of cylinder four pulleys one of which is marked 17..
One stroke of the piston effects a rise and the back stroke the fall of the saloon,
seats, platforms, berths, floors, or hammocks as the case may be. The speed at
which the rising is effected can be regulated by the steam valve of the pump and
the falling too in the case of the double acting piston.
The falling may be regulated by a stop cock or valve 53 Fig. 10 sheet 2 placed
in the exhaust passage 35 by which the escape of the water can be controlled.
Fig. 8 sheet 1 shews a saloon to be controlled according to my invention.
I prefer to place it low down in the ship in order that it may turn on an axis
coinciding as nearly as may be with the axis on which the ship rolls by the motion
of the waves, or more correctly the axis on which the ship rolls about the saloon.
after the manner of the Bessemer şaloon. Patent No 4258-1874. 73 and 73ª are
E

page_text: girders that cross the ship, 72 and 72° are bulkheads, 75° and 75° are the axils or
trunnions on which the saloon swings.
The saloon is heavily weighted below the trunnions as low down as possible in
order that it may keep level when the ship rolls.
The general construction should be the same as in the said Bessemer saloon.
Stained or ground glass may be used for the lights. When the hydraulic
rams cause the cable or wire rope 24 to move in the direction of the arrow
the saloon rises there are four cables connected to the cable 24 at 24' only two
of which are shewn in the drawing 24 and 24b, the cables pass over the pulleys
and are connected to the uprights 25°, 25, at 24° and 24ª, the uprights are so fitted
with rollers as to be able only to move up and down, this part is fully explained
in my invention herein before refered to, on the other side of the axil there is
another set of pulleys the same as 24°, 24', 24, 24h, 24'
The apparatus may be worked without the electrical part by disconnecting the
electro magnets and controlling the spindle 33 by hand by means of the bandle 40°
Fig. 5. sheet 2.
The steam winding system herein before refered to may also be worked without
the electrical part, and the resisting body in the water, by controlling the starting
valve by hand which should have a lever handle for the purpose.
If it should be desired to fix the saloon at any time so that it may move as the
ship moves it may be done by means of the break, to each of the uprights 25dª, 25°,
is fixed a segment of a circle 74, 74° they have rollers at each end one is shewn
at 74 another at 74, now when the break blocks are forced against the segments
in any position, better of course in the lowest, by the break levers 76, 76° the
saloon is fixed and rolls with the ship. The action of the break is this, when the
break wheel 77 is turned it causes a worm W to turn the segment of a worm
wheel V and jam the break block against the upright 25ª at the same time a cable
or wire rope 80 that passes over a drum on the axil on which the break lever turns
as shewn by the dotted line and over a similar drum on the axil of the lever at
the other end of the saloon, by this means both breaks are put on at once, the
weight on the end of the lever 76 takes the break off when the other break is
released. Strong bolts may be pushed through the break block into the uprights
to make the fixing secure by the hand levers O. P.
Fig. 13 sheet 2 shews a means by which passengers may enter or leave the saloon
while it is in motion or to be more correct while the saloon is nearly at rest and
the ship is in motion, a bridge 69 is jointed to the deck 70 at a and to a sliding
stage 69 at b, at any time a passenger can walk along the bridge and on to the
sliding stage 69 and then step on to the fixed stage or landing 70b down the
steps 70° to the floor of the saloon, or leave the saloon by the same means. Fig. 8
is a plan of the same. A staircase enables passengers to pass from the floor of the
saloon to the promenade deck, of course the structure that I have called the saloon
may be partly fitted with sleeping cabins.
The saloon or other apparatus may simply rise and fall in relation to the ship
like an ordinary lift that is without any mechanism to prevent rolling or pitching.
Figs. 1 and 7 sheet 1 and 2 shews the application of my invention to a Bessemer
saloon in this case the chains are dispensed with and the rams one at each end of
the saloon work the saloon directly, 62 is the hydraulic cylinder that works the
saloon 58 for the swinging motions. When the rams rise one of which is 63 the
saloon rises and with it the frame 07 to which is attached the rollers a, b, c that
work against the cylinder as a guide, the piston rod of the cylinder 62 is jointed to
this frame and obtains the resistance by which it may work the saloon from it and
as the frame rises with the saloon it can control the angle of the saloon whether
the saloon is up or down or in any position.
60 is a massive frame one to be at each end, at the top of which the guide
block 61, that carries the trunnions of the saloon work in. Fig. 7. sheet 1 shews
a front view of the same end of the saloon..

page_text: The direct acting rams may be applied to the saloon shewn in Fig. 8 that is to
a saloon kept from rolling by gravitation. 71 is the joint by which the water
under pressure is conveyed to the cylinder 62 through the trunnion this is better
shewn in Fig. 11, the water under pressure is supplied to the tube 74 and enters
the case 71, the tube 72 is connected to the trunnion of the saloon, a small tube
extension of the trunnion passes through stuffing boxes or leathers in a case
similar to 71, it will be seen that the extension of the trunnion can turn in the
case 73 and that the tube 72 can slide in the case 71 and that the water can pass
from the tube 74 through the hole 75 along the tube 72 through the hole 76 into
the trunnion at all times when the ship is rolling and when it is rising and falling
as the saloon rises and falls in relation to the ship. The water, or the pressure;
can be conveyed from the trunnion to the apparatus that controls the ram 62, in
some cases a cylinder like 62 is placed on each side of the trunnion in the
Bessemer system. Fig. 11 shews the tube 72 U shaped to save space..
In order that my invention may be perfectly understood I will now explain the
action of the apparatus when the ship falls with the waves in order that the saloon
or other apparatus may remain nearly motionless as regards the up and down
motion.
The effect of the falling of the ship is to cause a pressure on the underside of
the resisting body 2, or an upward pressure this makes the line 120 slack and the
spring 128, presses on the contact or pressure lever 12b, and the current passes
from the electric generator 100 along the line 12c, 12c through the lever 12b and
line 47° to the electro magnet 47 which attracts the armature 45 to it but kept
from actual contact by the stops 33" striking against the pad 33° the spring 46'
tends to keep the armature central beteen the two magnets, the armature by the
above action draws the spindle 33 out and places the slide valve 33 in the
position shewn in Fig. 7, and the water under pressure in the case 27, supplied
by the pipe 36, acts on the small area side of the piston 29 the water on the
other side of piston exhausts through the port 39° into the common exhaust
pipe 38, the piston 29ª carries the plate valve 31 with it and opens the port 34*,
the water under pressure now goes, or communicates the pressure by the pipe 34
to the hydraulic cylinder 25 and by the ram being forced outward the saloon, or
other apparatus is caused to rise in relation to the ship as the ship falls, at the
same time the pressure is communicated by the small port 34° by the passage 34b
shewn in dotted lines to the piston 28a which moves the valve 30 and closes the
port 34'and stops the apparatus after the piston or ram 20 has travelled a certain
distance the speed at which the piston 28 noves is regulated by the handle 54
to suit the height of the waves at the time. The moment the ship begins to rise
a down pressure is produced on the resisting body 2 which produces a tension on
the line 12 which makes contact, or produces pressure between 12b, and 12k, and
the electric current passes from the electric generator 100 as before along the
line 12, 12, through 12b to the line 47d to the electro magnets 47 excites the
magnets and attracts the armature 45 and pushes in the spindle 33 which allows
the water under pressure, or the pressure to be communicated from the case 27
through the passage 39 and through the port 29b to the large area side of the
piston 29 this puts the ports 34 and 34° in communication with the exhaust 35b
and the ram 20 is forced inwards and the saloon and other apparatus fall in
relation to the ship at the same time the piston 28 connected to the valve 30
closes the ports 34, and 34°, after the ram has travelled a certain distance and
stops the ram 20 as before, the stroke of the valve 31 both ways is regulated by
the adjustable stops 31° and 32b striking against the buffer 32°.
The contact or pressure lever and the lines and electric generator are only shewn
in diagram forin. These parts are properly explained in the specification of the
before said Patent.
I am aware that hydraulic power has been applied to apparatus with the object
of preventing sea-sickness by stopping the rolling and pitching motion of a saloon
or other apparatus and there is no doubt that a part of the rolling or pitching.

page_text: motion is a vertical motion, but when all rolling and pitching is prevented there
is still a rising and falling motion and it is that kind of motion that I claim to be
the first to prevent by means of hydraulic power as hereinbefore described.
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 case or shield by preference cigar or fish shaped, with a cluster of holes or
openings at opposite sides, the case being supported in such a manner that the
holes are at the top and bottom, substantially as and for the purpose set forth.
2. The method by which the resisting body or surface is jointed to the rod to
which the line is attached that works the electrical apparatus on board the ship,
substantially as and for the purpose set forth.
3. The method of controlling the cut off in the winding engine system by means
of a small wheel pressed in contact with a large disc, substantially as and for the
purpose set forth.
4. The method or mode of neutralizing or preventing up and down motion in a
saloon, berths, seats, hammocks, platforms, cabins and floors by hydraulic power
obtained from the action of a steam pump, furnished with an air chamber, and a
relief valve, substantially as and for the purpose set forth.
5. The combinations with the electrical apparatus described in the herein before
said former patent, altered as herein described and explained, and the hydraulic

6. In apparatus for the prevention or relief of sea-sickness that act on the
principle of preventing or neutralizing the up and down motion The hydraulic

as and for the purpose set forth.
7. The method or mode of controlling the starting valve of hydraulic valve
apparatus by an armature connected, either directly or acting through an auxiliary
piston and cylinder, or engine, to the valve spindle, motion being given to the
armature by electro magnets substantially as and for the purpose set forth.
8. The method of controlling the water or other liquid under pressure by the
arrangement of valves, cylinder piston balanceing pistons, as shewn in figures 2, 5, 7
sheet 2, substantially as set forth.
9. The combination with two electro magnets and armature, and the arrange-
ment of valves by which the starting, stopping, and reversing is effected as shewn
in Figures 2, 5, 7 sheet 2, substantially as and for the purpose set forth.
10. In apparatus for the prevention of sea-sickness that act on the principle of
preventing or neutralizing the up and down motion, the arrangement of the ports
on the valve. face by which the water under pressure is communicated to and from
the working hydraulic cylinder or rams, and also to the cut off piston, substantially
as set forth.
11. The method or mode of actuating the cut off or box valve by being
connected to a hydraulic piston working in a cylinder one side of piston being
exposed to, or under a constant fluid pressure the other side of piston being open
to the exhaust and pressure alternately, substantially as and for the purpose set
forth.
12. The method or mode of regulating the time or the speed of the cut off so
that the motive or power ram, or rams may move the load through a greater or
less space at each stroke, at will, by means of a cock or valve that contracts or
opens the passage that communicates the pressure to, or exhausts the small
hydraulic piston, that works the box valve, alternately, substantially as and for
the purpose set forth.
13. The method or mode of driving the starting valve by a sinall piston
working in a cylinder the electric magnets giving motion to the slide valve that
