This invention relates to pocket knives with sliding blades
One important feature of this invention is the employment of a push knob
provided with two projections, a neck and a head and fitting into a vertical notch
formed in the rear end of the blade in such a manner as to be capable of receiving
an upward or downward movement. Below this vertical notch is a horizontal
notch in which is placed a spring one part of which presses upon the underside of
the push knob. The handle of the knife is hollow to permit the blade to be drawn
back into the same. The back of this handle is provided with a slot in which the
neck of the push knob slides when the blade is moved into or out of the said
handle. This slot is made wider at the top of the knife in order to ensure the
fixing of the blade as hereinafter described. The sliding of the blade in this knife
is effected in the following manner that is to say:-The push knob is caused to
slide along the back of the knife moving the blade with it until the said push knob
arrives at the wide end of the slot immediately above the horizontal notch above
mentioned when the said knob is pressed upwardly by the spring placed in the
said notch, the body of the said knob filling up the widened end of the slot whilst
its neck projects from the sheath or handle; the sliding back of this push knob
being thus prevented.
The projections of the said knob prevent the same from springing too far out.
When it is desired to sheath the blade in the handle the head of the knob is passed
down until the neck of the same is level with the slot, when the knob and
consequently the blades are capable of sliding back again. When the knife is
sheathed in the handle the spring presses the shoulders of the knob firmly against
the underside of the edges of the slot, and thus prevents the blade from sliding.

front, the spring acting also upon the knob in the same manner as hereinbefore
described when the knife was unsheathed.
This widening of the slot is not indispensable in ordinary knives as the pressure
of the knob upon the underside of the edges of the slot is strong enough to keep the
blade in its place; this widening can moreover be effected if desired in any part
of the slot in order to be able to fix the blade in any position

Office of the Commissioners of Patents on the 15th February 1883.
ALFRED AUGUSTUS AKERMAN of 23 Wilmington Square, in the County of
Middlesex "IMPROVEMENTS IN MEANS AND APPARATUS FOR DESTROYING
INSECT VERMIN,"
The object of my said invention is to effect the distruction of insect vermin in a
simple and efficient manner, by means of high pressure steam.
The apparatus consists of a small steam boiler, of a convenient size and shape to
be carried in the hand, and heated by means of a small spirit lamp
Although the form of the boiler may be very much varied, I prefer that of an
upright cylinder mounted on a flat metallic plate, the lower part of the cylinder
being cut away to admit the introduction and withdrawal of the lamp. At a
suitable distance above the lamp a circular plate is brazed or soldered to form the
bottom of the water chamber. The top of the boiler is similarly fitted with a
plate to form the top of the steam space. A circular opening in the upper plate
serves for a safety valve port. A slip of metal or wire is brazed to the side of the
boiler to form a handle. An additional handle is also fitted which can be raised
and lowered on a centre near the top of the boiler.
One end of this handle is furnished with a valve, which can be made to close
the safety valve port when necessary
A small steam pipe, without any cock, is also fitted to the boiler to direct the
emission of steam to the desired spot.
When the apparatus is used, the boiler is partially filled with water; the
spirit lamp is then lighted and put in its place. As soon as the water boils, the
boiler is taken in the hand: the valve is closed until steam issues with sufficient
force from the nozzle of the steam pipe The jet of issuing steam is then directed
to & into any spot or recess where insect vermin or their eggs or larvae may happen
to be, and they are destroyed by the issuing steam at a high pressure and
temperature
By means of my said invention the joints of bedsteads, & other places where
insect vermin or their eggs or larvae may be located, can be thoroughly cleansed &
purified

"IMPROVEMENTS IN TELEGRAPH CABLES
"
This invention has for its object improvements in telegraph cables.
At the present time great inconvenience is experienced from the kinking of
telegraph cables when laid in deep water. To avoid this is one of the object of
my invention. Another object is to provide an efficiently protected cable with
less weight than is necessary when wires are used as the protective covering.
The core of the cable is constructed as at present, whether it be to contain a
single insulated conductor or several and it is also lapped or served with fibrous
material in the usual way. Around this I lay a series of flat bands of galvanised
iron or steel or other protecting metal,-These bands are thin and of a breadth
equal to several times the thickness-they are laid so as to abut the one on the
other edge to edge and so as to form a complete metallic sheathing. Over the
sheathing the cable receives a serving of fibrous material.

The present invention relates to further improvements in slide valves for which
Letters Patent were granted to me N° 3687 dated the twenty fourth day of
August, one thousand eight hundred and eighty one and the said improvements
have for object to simplify the construction and reduce wear and consist in
employing one rod instead of two for connecting the slide valve with the piston
which balances the slide valve; in constructing the piston in one piece thereby
avoiding the use of a cap with corresponding pivots and stops; in packing the
piston with three small rings in place of one of complicated construction.
I also modify the pivots and the respective eyes of the connecting rod where
the pressure of the fluid is concentrated; this pressure on the piston and on the
back of the valve produces, when two rods are employed as in my said former
Letters Patent, great wear at the point of contact of the pivots with the corre-

slide.
Further, I now provide the eyes of the connecting rod, at their points of contact
with the pivots, with steel bearing pieces or bushes let into the eyes in such a
manner as to allow of their being easily replaced when worn, without necessitating
any alteration or change in the connecting rod which remains intact.

My said invention relates to improvements in mariners compasses combined with
automatic registering devices for the same and consists in so combining the ordinary
mariners compass with automatic registering devices for the same that every
deviation in the course of the ship is registered or recorded on suitable sheets of
paper or other suitable material that is to say the apparatus registers not only the
exact course the ship was steered but also the hour minute or second when such
variation in the ships course ensued and the force and direction of the wind.
In order to carry my said invention into effect I employ a suitable clockwork
and arrange appropriate discs of suitable material on each side of such said
clock work in such manner that the racks and the pointers and pencils or other
marking arrangement of the said clockwork is in connection with the aforementioned
discs. Each of these plates is provided with a series of concentric lines and the
various marks as on the compass id est. N. S. O. W. etc. The racks or other
suitable mechanical appliances arranged at the upper part of the said clock
work are provided with suitable writing points so as to mark on such said
sheets dials or discs each and every deviation or alteration in the course of the
ship, the time such deviation or alteration took place and the exact direction in
which the ship was steered. The clockwork is made to run 24 or more hours.
According to my said invention the ship owner or any other person is able to
thoroughly controll the course of the vessel even after years, and to decide in case
of collision stranding or such like who was to blame for such said collision, stranding
or other accident at sea.
A small flag, wind denoting or registering apparatus is attached to the one disc
employed for registering the direction and force of the wind.
One of the said discs is in connection with the steering apparatus so that each
and every movement of the steering wheel will be transmitted to the said disc and
the exact time marked on the said disc when such movement of the steering wheel
was effected, whereas the other disc is rotated by means of the small flag or other
apparatus for denoting the direction in which the wind blows.

THOMAS HOBERT BALL, of Chicago, Illinois, United States of America,
"IMPROVEMENTS IN THE CONSTRUCTION OF STEAM AND OTHER SHIPS "
My invention relates chiefly to the construction of steamships, but can also be
applied to all ships in which screw propellors are employed
The main object of my invention is to provide a ship with two propellors placed
in such positions that the pitching of the vessel will not injuriously affect their
action
My said invention is further designed to facilitate the steering of the ship.
For these purposes I proceed as follows, that is to say-I make the forward
part of the vessel from amidships or thereabouts of greater beam than the after
part of the vessel, and I construct the vessel in such a manner as to leave a space
on each side of the same at the point of junction between the narrower and wider
parts, for a propellor to be fitted. In each of the projecting parts of the vessel I
arrange a screw-propellor and its operating mechanism. These propellors may be
of any well known description and are fitted in the ordinary manner. They are
operated either by separate engines or by a single engine and can be so arranged
that they may be caused to rotate in opposite directions and thus turn the ship in
one direction or the other. I propose in most cases to make use of the ordinary
propellor at the rear as well as of the two side propellors. above described.

JOHN IMRAY of N° 28 Southampton Buildings, Chancery Lane, in the County
of Middlesex "AN IMPROVEMENT IN THE CONSTRUCTION OF IRON OR STEEL
VESSELS
[communicated to him from Abroad by Aristide Baude of Paris,
France.]
93
This invention relates to a mode of constructing iron or steel vessels, whereby
with a given weight of material greater strength is obtained than by the ordinary
modes of construction, and leakage at the joints of the plates is more effectually
prevented. For this purpose, instead of overlapping the plates of the successive
tiers and rivetting them to each other, there is interposed between each tier of
plates and the next in order a horizontal band forming a rib projecting inwards at
right angles to the contour. On each side of this band is rivetted an angle iron
and to these angle irons are rivetted the plates of the two tiers, the edge of the
band being made to project a little beyond the external surface of the plates, and
being afterwards caulked down by the hammer so as to form a continuous burr or
rivet covering the edges of the adjoining plates. The bands are made of greater
breadth in the lower part of the hull and in the middle of the vessel than they are
in the upper part of the structure and towards the ends of the vessel, so as to form
deeper ribs where greater strength is required. Where a a floor is required it may
be of wood fixed on angle irons rivetted to the inner edges of the of the deep
bottom ribs, or flat bars crossing each other diagonally may be secured to these
angle irons so as to give increased rigidity to the structure. The decks are laid on
girders which at each end, where they meet the sides of the vessel, are widened out
in knee form and are secured by angle irons to the plates and to the two inwardly
projecting ribs, the one above and the other below the knee end of the girder.
The bulkheads are notched at the sides for the passage through them of the
continuous horizontal ribs and their angle irons, which as well as the plates are
secured to the bulkheads by angle irons and suitably bent covering plates rivetted
to both. In constructing a vessel in this manner, it is convenient in the first place
to make the bulkheads with their notches in the proper places to receive the ribs,
and to set them up at the required distances apart so as to form a frame work to

page_text: which in the first place the horizontal ribs are attached, the plates being then
rivetted to the ribs. When the distance from bulkhead to bulkhead is too great to
afford proper support to the ribs, temporary framings can be erected between them
to carry the ribs until the plating is done. In order to prevent lodgement of
water on the horizontal ribs, drainage holes are cut through them at intervals, care
being taken that these holes in the several ribs do not come in vertical lines, which
would have the effect of weakening the structure in these places.
IMPROVEMENTS IN THE FASTENING OF FISH-PLATES TO ALL FORMS OF RAILWAY RAILS AND TRAMWAY RAILS.

JAMES GLOVER of 30 Crosby Road, in the parish of Birkdale, Lancashire Civil
Engineer and CORNELIUS WALTON of 63. Queen Victoria Street, in the City of
London, Engineer IMPROVEMENTS IN THE FASTENING OF FISH-PLATES TO ALL
FORMS OF RAILWAY RAILS AND TRAMWAY RAILS.
This invention relates to an improved method for securing fish plates to rails of
all sections used in the construction of all Railways and Tramways.
The Improved methods consists of screwbolts being used instead of bolts and
nuts, the said screw bolts being screwed into proper sized tapped holes in one of
the fish plates, the shanks of the said screw-bolts pass through clear holes in the
first fish plate and the customary clear holes in the rails.
The first improvement consists in a more permanant fastening being obtained,
the screw bolt not having the same tendency to work loose by the vibration, which
is caused by trains or trams passing over the rails as in the case of fastening by
nuts and bolts.
The second improvement, consists in less material and fewer parts being required
per mile of Railway or Tramway and the reduction in working expenses due to
less labour being involved in the tightening and screwing up of nuts at frequent
intervals entailed by the nuts working loose as in the ordinary fish plate bolts,
there being no nuts used in our method.
The third improvement consists in less attention being necessary after the fish
plates have been once properly fixed, and in their not working loose so easily as
the ordinary nut fastenings whereby the roads will be maintained in a more
efficient state, and the bad effects on the rolling stock &c. &c. due to joints not
properly fished or which have worked loose, will not attend the use of our method

"IMPROVEMENTS IN LAMPS AND LANTERNS
"
My invention relates to an improved construction of lamps or lanterns whereby
I am enabled to burn colza and other vegetable or animal oils, with a perfectly
steady flame, without the use of a chimney glass, while, at the same time a much
more brilliant light is obtained than with ordinary oil lamps or lanterns, with a
less consumption of oil and wick.
For this purpose, I fix upon a plate, which is slid into the bottom of the lamp,
an oil reservoir, by preference of the kind known as a "bird's fountain," which
supplies the oil to a wick-tube projecting up some distance from the said plate.
Surrounding the wick tube is a tubular enclosure, also fixed to the said plate, to
the top of which is hinged a cap having a slit or opening corresponding to the
configuration of the wick, and arranged at such a height as to be a certain distance
above the top of the wick. In the annular space between the wick holder and
enclosure, numerous perforations are formed in the base plate, through which air
can pass into the said annular space, and this air supply, in being drawn upwards
by the draught, is firstly heated to a certain extent by contact with the heated
wick-tube and enclosure, and is then caused by the cap to impinge against the
flame, thereby effecting a very perfect combustion, resulting in a very brilliant,
steady, and practically smokeless flame. The bottom of the lamp is formed with
perforations for the entrance of the air, and perforations are also formed in the
part of the before-mentioned base plate surrounding the enclosing tube of the
burner, through which air also passes up in the body of the lamp and in contact
with the flame. This construction of lamp is particularly applicable for use is
exposed places, such as for the head and tail lamps of railway trains, ship's lanterns,
carriage lamps and the like, but it may also be employed with advantage for other
descriptions of lamps and lanterns

"AN IMPROVED METHOD OF AND APPARATUS FOR, EXPANDING THE ENDS OF BOILER
TUBES IN THEIR TUBE PLATES." [Communicated to him from abroad by David
Henry Cunningham, of Paris France]
This Invention relates to an improved method of and apparatus for expanding
the ends of boiler tubes in, and for the purpose of setting them in the tube plates of
locomotive and other tubular boilers.
The improved method consists in simultaneously expanding the tube on the
inner or water side of the tube plate, and expanding or upsetting the end of the
tube on the outer side of the plate, this double operation being performed with
the aid of the tube expanding tool which I will hereafter describe. By this
method the tubes are made perfectly tight, the tube plates are greatly stayed and
strengthened by the tubes being clinched on both sides of the plate, so that the
joints are not liable to open and leak in consequence of the elongation of the tubes
or the expansion of the boiler plate by heat as when the ends of the tubes are
simply upset against the outside the tube plate. On the contrary, the expansion
of the tubes makes the joints tighter, and moreover ordinary iron tubes can be
made perfectly tight without having copper ends brazed on to facilitate making a
tight joint.
The improved tube expander consists of a mandrel and of two circumferential
sets of elliptical rolling dies respectively arranged to operate circularly within the
tube at a point just inside of the tube plate and on the end of the tube outside
said plate. The mandrel is constructed mainly of a central spindle and of a pair of
hardened steel cones slipped upon the spindle with their apexes facing each other.
The peripheries of these cones form the bearing surfaces for the dies which roll
around the cones. The dies are egg shaped and have their larger ends towards the
apexes of the cones and they are enclosed and retained in position by a tubular
shell having holes through which the rolling dies can project freely to a sufficient
Pin D71

circle or set preferably alternate with those of the other circle or set, the distance
between the two sets depending upon the thickness of the tube plate. The cones
are confined between a head or collar fixed on the one end of the spindle, and an
adjusting nut screwing on the other end whereby they may be drawn together in
order to expand the tool by throwing the dies outwards after being inserted in the
tube and from time to time as the tool is rotated in the tube by a wrench applied
to the spindle.

This invention relates to the construction of an improved movement for swing
looking glasses, the said movement being also applicable for swing sashes, ventilators,
and the like, also for other articles which have a swinging movement, telescopes,
paper clips, curtain rod holders, turnbuckles and for various other purposes.
For the purpose of illustration I will describe my invention as applied to a swing
looking glass.
I employ a barrel or short cylinder closed at one end; within the barrel I adapt
a spring arranged by being partly bowed or otherwise to press tightly against the
interior periphery of the barrel; the two ends of the spring are bent down at right
angles and serve as a means for the spring being operated by means of a slotted
stud on a cover which fits into the open end of the barrel: a central stud or pin is
provided to allow of the cap and spring turning within the barrel or vice versd;
on the outside of the cap is an inclined projection over which can slide a slotted
plate.
The action is as follows: the slotted plate is fixed to the frame of the glass and
the barrel is fitted to one of the standards supporting the glass, or the slotted plate
may be fitted to the standard and the barrel to the looking glass frame; the glass
can then be placed in its standards and will be kept at any angle at which it may
be placed by the pressure of the hereinbefore described spring against the interior
periphery of the barrel; a movement may be applied at one or both sides of the
glass if necessary
The application of my improvements to other articles or purposes will be
understood without further description.
Instead of the hereinbefore described spring pressing against the inner periphery
of the barrel I sometimes place between the spring and the barrel a lining of
suitable metal such as iron or steel which lining being moved carries with it the
spring.

IVAN LEVINSTEIN, of the City of Manchester, in the County of Lancaster,
Chemist. "IMPROVEMENTS IN CONVERTING ANTHRAQUINONE INTO A MONOSULPHO-
ACID OF ANTHRAQUINONE, ALSO APPLICABLE FOR TREATING OTHER ORGANIC
COMPOUNDS,"
My invention relates to and consists in a mode and arrangements for converting
Anthraquinone in one operation substantially into a mono sulpho acid of
Anthraquinone.
In the present process of manufacturing the mono sulpho acid of Anthraquinone
there are obtained three products, namely, Anthraquinone not acted upon by the
fuming sulphuric acid mono-sulpho acid of anthraquinone, and a disulpho acid of
Anthraquinone; these products inust be afterwards separated from each other in a
manner well known.
By my method the advantages are the saving of anhydrous sulphuric acid and
also economy in the general working of the process.
To carry out my invention I use pans preferably enamelled inside entirely closed
when in use, and provided with a mechanical stirrer or agitator-the axis of
which is hollow, and is at the bottom perforated and projects slightly over the
driving wheel, the projecting end being connected with a tap.
When the operation is finished, air is forced by any suitable means into the pan,
and its contents are discharged through the hollow agitator shaft. The pan is
provided with a safety valve and is charged with material through a manhole, and
is heated preferably by an oil bath.
I charge the pan, when I desire to produce a mono sulpho acid with say 5°
more than the calculated or theoretical quantity of the necessary anhydrous

other apertures from the pan and raise the temperature of the oil bath by which
it is heated to about 170° C, and keep it at this temperature-stirring the mass
continually until a sample of it dissolves practically in water.

IMPROVEMENTS IN CONNECTION WITH GAS RETORT FURNACES FOR GENERATING
HEAT
"
The object of our Invention is to utilise the waste heat or gases arising from
retort benches or settings whereby a saving in fuel is effected. For this purpose
we make the furnace much deeper than at present constructed so as to obtain a
large body of coke and we construct and arrange at each side of the furnace a series
of zigzag flues or openings which at one end are in connection with the furnace
whilst the other is open to the atmosphere and in connection with the usual flues
employed for removing the heat and gases. The quantity of air supplied to these
flues being regulated by dampers.
The bricks we employ for forming the newly arranged flues are of peculiar
construction, being dovetailed into each other, and when put together form openings
or flues at right angles to each other. The spent gases pass through one of these
flues whereby the bricks are heated, so that the atmospheric air in passing through
the other flue becomes heated and when it enters into the upper part of the furnace
it mingles with the carbonic oxide which is immediately ignited, and materially
assists in heating the retorts. The heated air enters the furnace in thin sheets by
means of narrow horizontal slits formed in the bricks.
This construction of heat generator may be used in connection with, either grate
bar furnaces or that constructed on a V principle and can be applied to existing
settings at a much less cost than the present construction of heat generator. In
order to break the clinkers so that a supply of air may be freely admitted to the
fire when constructed on the V principle, we employ a lever provided with prongs

level with the furnace. The pronged lever is placed underneath the fire with the
prongs passing through the slit entering into and amongst the fuel. At the rear of
the lever is connected one or more pulleys forming a carriage running upon rails,
so that the workman can run the wheels and lever backwards and forwards con- 5
sequently sliding the prongs to and fro in the slit and so breaking the clinkers in
the furnace and allowing for the admission of air.

ROBERT VACY ASH of 45 Marylands Road Saint Peters Park West in the
County of Middlesex "AN IMPROVED APPARATUS FOR STRETCHING TROUSERS OR
OTHER SIMILAR ARTICLES OF WEARING APPAREL
"
The object of the Invention is for the purpose of stretching trousers or other
fabrics of a similar and like nature and consists in the application of clamps and a
stretching medium such as india rubber or metallic springs so applied that an
automatic pull or stretch of the articles retained between the clamps will be given
thereto. The manner in which I carry out my improvements may be described as
follows-
I fix to one end of a metallic rod or tube a clamp which is so arranged and
strengthened that when a piece of fabric is placed between its jaws and the top
clamp a jaw is fastened down by an eccentric, clip, wedged link, rack or their
equivalent the fabric between the jaws of the clamp will be firmly retained.-This
metallic rod is also provided with a second similar pair of clamps which are so
arranged to slide thereon so as to have their position adjusted with respect to the
fixed or first pair of clamps, this second pair of adjustable clamps have securely
attached to then an india rubber spring so placed that when the fabric to be
stretched is distended between the fixed and moveable clamps the said india
rubber spring is pulled back so as to draw with it the sliding clamp which said
india rubber when so distended or stretched is hooked on to a fixed projection on
to a fixed projection on the said metallic rod or tube in which state it gives a full
pull or stretch to the fabric retained between the clamps.
It will be understood that in lieu of india rubber metallic springs may be
employed and a further mechanical distention may be given to the pull of the india
rubber by forcing between its looped or V formation when distended a stretching
bar or its equivalent.

HERBERT FRANCIS BROOKS of N° 60 South Quay, Great Yarmouth in the County
of Norfolk Shipping Agent "IMPROVED APPARATUS FOR USE IN DEEP SEA
FISHING OR TRAWLING
DJ
The improvement of the trawling apparatus has reference to the trawl heads.
The objects of the invention are to enable larger trawl heads to be used without
materially increasing the weight of the apparatus, also so to construct the trawl
heads that whilst great strength is obtained thereto, wringing or twisting of the
trawl heads may be prevented. Also so to construct the caps or joggles of the trawl
head for attaching thereto the beam, that the shape of the same may not be liable
to alteration in fitting them on to or taking them off the beam. Also to enable the
"Sole" to be disconnected from the "bow" or Rim for renewal or otherwise
without the aid of skilled labor being necessary and generally to obtain a much
better appliance without any great increase of cost of manufacturo.
In carrying out the invention I form the trawl heads of iron or steel of double
flanged or other suitable section or partly of such flanged form of section and partly
such as the sole portion, of plain rectangular section.
The caps or joggles may be constructed of like material and sectional form and
they are attached to the heads by bolts and nuts rivets or such like means of
attachment.
The sole is attached to the bow or rim portion of the trawl head by rivets or
bolts and nuts or other suitable means of attachment and thereby admit of those
parts being separated and the worn or damaged parts being removed and another
substituted and fitted without the aid of skilled labor being required

WILLIAM JAMES DONDERDALE of Huddersfield in the County of York, Land
Agent and Surveyor-" IMPROVEMENTS IN CONNECTION WITH WATER TAPS
"
The object of my Invention is to construct and arrange taps and apparatus in
connection therewith, so as to prevent water coming from the service pipes
impregnated with lead, and passing into utensils when such water is intended for
domestic consumption
My Invention consists in the use or employment of two taps (or a double tap)
one placed above the other, the valves of which are operated by the same spindle
and so arranged that when one valve is opened the other valve is closed
In connection with the two taps is a chamber or vessel of such a size, as to
contain the stagnant water which is lodging in the lead pipes, between the drawing
tap and main or cistern.
"When it is intended to draw water, the valve spindle is operated, whereby the
upper tap is opened and the lower one closed, which allows the water from the
service pipe to flow into the chamber until full; by which time the stagnant water
would have escaped from the service pipe into the chamber
The water from the service pipe would continue to flow, but instead of passing
into the receiving chamber which is now full, it ascends a branch pipe connected
to the top of the chamber and escapes therefrom
By this means only clear and unpoisoned water can be delivered
When sufficient water has been drawn the valve spindle is reversed, whereby
the upper tap is closed and the lower one opened allowing all the water in the
chamber or vessel to pass away.
IMPROVE- MENTS IN REGULATORS OF LEVEL IN STEAM BOILERS

PAUL GAUCHOT of 103 Quai Valmy in the City of Paris Engineer "IMPROVE-
MENTS IN REGULATORS OF LEVEL IN STEAM BOILERS"
This Invention relates to an improved water level regulator for steam boilers
consisting of a float whose range of movement is extended or amplified relatively
to the fluctuations of the level in the boiler by means of a supplementary level or
body of water communicating with the boiler as hereinafter described whereby
the said float is enabled to act upon a stop valve which according to the position of
the float opens or closes the passage or inlet by which water is supplied to the
boiler
•
In carrying out this Invention the apparatus is constructed with a bottle or
chamber communicating with the boiler through a passage or pipe which descends
inside the boiler to the level at which the water is to be maintained If the water
rise above the normal level when the boiler is heated the end of this pipe is
immersed in the water whereupon the steam confined in the bottle is cooled and
condensed. The water in the bottle then rises in the pipe and completely fills the
chamber or bottle. This chamber contains a float affixed to one extremity of a
lever turning on a fixed centre and provided at the opposite extremity with a Cam
surface hereinafter referred to-A valve interposed in the passage for the admission
of water to the boiler is provided with a rod or stem which when the float is raised
by the water filling the chamber as herein before described is acted upon by the said
Cam surface which thus operates to close the said valve-When the level of the
water in the boiler sinks sufficiently to expose the end of the pendent pipe the
water contained in the Chamber flows back into the boiler the float is lowered and
the lever connected to the float allows the valve to open and admit water to the
boiler The chamber being thus filled and emptied alternately the float which it
contains is alternately suspended in an atmosphere of steam without other support
than the lever and then entirely immersed in water being thereby enabled to exert
all the power of which it is capable. The valve is preferably constructed in the
form of a piston working in a Cylinder but may be made in any other suitable
form according to circumstances

page_text: In order to render the motion of the float visible externally the lever is provided
with an indicator such as a rod passing through the side of the chamber and
enclosed in a glass tube
In order to throw the apparatus out of action in case of need a bye pass pipe
provided with a stop cock is employed which when open neutralizes the action of
the regulator by providing a passage communicating with opposite sides of the
valve When the stop cock is closed the apparatus is again brought into action
IMPROVEMENTS IN THE SLEEPING BERTHS OF RAILWAY CARRIAGES AND STEAM BOATS
Year: 1883

Office of the Commissioners of Patents on the 14th February 1883.
THOMAS FEWSDALE CRAVEN, of 27 Westbourne Road in Sheffield, in the County
of York, "IMPROVEMENTS IN THE SLEEPING BERTHS OF RAILWAY CARRIAGES
AND STEAM BOATS
"
This Invention relates to improvements in mechanism for raising and lowering
berths in Railway Couches, and on Shipboard, more especially where berths or a
berth is required in a position over or above another berth or seat, in which case it
is desirable that it should be secured for use at a convenient distance from the seat
or lower bed, and also from the ceiling of the compartment; it is also desirable
that efficient means should be provided for raising the berth when not in use, and
securing it so as to permit the lower berth being used as a seat if required.
I propose to accomplish this by the following mechanism:-I provide a screw
and nut to work between grooved guides secured to the body of the couch; to the
nut I connect a hinge or bracket to carry the berth, and in order to reduce the
friction on the nut and the screw, I provide and arrange rollers to work on studs
on the nut, and in the grooves of the guides; I also place rollers on the brackets to
run against the face of the guides; and in order that the berth may be carried close
up to the roof or ceiling, I form projections of wedge like form on the face of the
guides, so that when the bracket, being hinged to the nut and having the rollers
running against the guides, reaches the proper height, it is, by the wedge like
projections, tilted so as to assume a position closely fitting the angle or pitch of the
roof or ceiling and be so secured.
I operate the screw by a handle in connection with bevil or screw wheels, and I
cover the opening between the guides by a band of any suitable material each end
of which being fastened to the nut, and passing over and under the supports of the
screw, it acts as a belt and effectually hides the screw and mechanism within the
guides, and also protects the same from dust or other obstruction.
It will be evident that with slight modifications this arrangement may be equally
well applied to the raising and lowering of Ships berths.
