"IMPROVEMENTS IN DIAPHRAGMS FOR GAS GOVERNORS OR REGULATORS; THEY
ALSO BEING APPLICABLE TO OTHER APPARATUS WHERE DIAPHRAGMS ARE USED
My invention relates to diaphragms used for lifting or working the valve or
valves in Gas Governors for preventing excessive pressure of Gas and the consequent
waste therefrom. Hitherto it has been the practice to make the diaphragm of
thin leather, india rubber, or other soft substance; the diaphragm is usually circular
and forms the roof of the Chamber of the Gas Governor, being secured thereto near
to its edge, the Gas entering this chamber expands or raises the diaphragm and by
that means lifts or works the valve, which is attached or connected to the said
diaphragm for the purpose of checking the inflow of Gas to the requisite quantity.
These diaphragms are objectionable because they are liable to become hard, to
crack, and thus be rendered inoperative; the action of the Gas affects them
injuriously and it is also able to percolate or leek through them which is not only
objectionable but dangerous. Diaphragms have also been made of metal but it has
hitherto been found necessary, when these latter have been employed to float or
work them in mercury oil or other liquid, which has necessitated mechanism more
or less complicated and costly.
According to my said Invention I obviate these inconveniences in the following
manner that is to say I employ in place of the leather rubber, or other diaphragms
herein before described, diaphragms of circular or suitable shape made of very thin
metal being an alloy of about 80 per cent of Tin, about 15 per cent of Lead and
5 per cent of Bismuth; which I have discovered not only makes a diaphragm of
sufficient pliability for the pressure of the Gas to expand or raise it and thus work
the valve in the necessary manner, but that it also resists the deleterious action of
Gas and water I have also employed diaphragms of Brass, Copper, Zinc, and Tin
plate and also an alloy of some of these metals, but have found them too tenacious
and liable to corrosion.
These diaphragms may be employed in any mechanism for which they may be
suitable, the essential feature being the employment of metal diaphragms as before
described which are more durable and more simple than others heretofore employed
MENTS IN BRAKES FOR CARRIAGES

Office of the Commissioners of Patents on the 6th December 1882.
EDMUND TUCKER ROBINSON of Cheshunt in the County of Herts " IMPROVE
MENTS IN BRAKES FOR CARRIAGES"
My Invention relates to improvements in Brakes for Landaus, Broughams,
Stanhope phaetons, and other similar four wheeled carriages and it has for its
object to enable the connection intermediate of the operating treadle or lever and
the brake blocks, to be so constructed and arranged, as, without presenting an
unsightly appearance to in no way interfere with, or be in the way of the fore
wheels when locked round, and so that the carriage may have as large wheels and
as short a wheel base as though it were unprovided with any brake.
According to my invention the brake connecting rod through which the pressure
applied to the operating treadle or lever is transmitted to the brake blocks is
arranged to pass centrally or otherwise through the structure itself of the arch
which connects the box or driver's seat to the carriage body so as to be quite out
of the way of the wheels under all circumstances and quite concealed from view.
And to enable this to be done the said rod is constructed in two parts, united by a
scarfed or other joint and bolts, the parts being inserted separately the one from
the front and the other from the rear and united when in situ, the latter part of
the rod being cranked or bent to pass beneath the body for the purpose of connec-
tion with the brakes. As applied to a square landau for instance the rod passes
straight through the structure of the arch (wherein it is jointed as above mentioned)
enters the body where it is cranked or bent to pass down behind the lining at
back of the front seat, through a hole beneath the Squab of the latter and so beneath
the body to the brake gear. At its rear end it is jointed to the inner and shorter
arms of a pair of levers pivoted beneath the body and extending laterally in opposite
directions from the central connecting rod, and whose outer and longer arms carry
the brake blocks in proximity to the hind wheels. A spring attached to the central
connecting rod or other part holds the brakes off the wheels except when overcome
by the pressure on the treadle or lever. The connection of the treadle or lever
with the front end of the connecting rod is such as to give the same a very short
stroke, a very slight forward movement of the said rod being sufficient to apply
the brakes.

JAMES PROCTOR, of Burnley, in the County of Lancaster, Mechanical Engineer,
"IMPROVEMENTS IN APPARATUS CONNECTED WITH THE FURNACES OF STEAM
BOILERS,"
This invention relates to improved combination of mechanism for imparting
reciprocating motion to the fire bars of furnaces and the invention is intended to
be used mainly in connection with my improved self-acting stoking apparatus
described in Specification of Patent No. 2017 of the year 1875.
On the Stoker shaft is a worin driving a worm wheel, a stud of which is received
within the slots of two levers one of such levers for each set of bars in a double
flued boiler, the other ends of the levers are connected or jointed to a bar the
latter communicating vibrating motion to a shaft which operates the furnace bars
by imparting a reciprocating notion to each alternate bar. Fingers or projections
entering recesses or slots in the bars and duplicate set of fingers being together
with levers, employed so as to carry all the bars forward at one time and bringing
them back by halves (i.e.) alternate bars.

HERBERT JOHN HADDAN, of Kensington, Middlesex. "IMPROVEMENTS IN
TOOLS FOR SETTING SAWS." A communication from abroad by Antoine Alfred
Rigaud, of Clermont-Ferrand, France.
This Invention has for its object to set the teeth of saw blades correctly and
rapidly by means of a simple tool. This tool consists of a short spindle, round or
prismatic and provided at each end with a groove corresponding to the thickness of
the saw blade. On one end of this spindle is mounted a movable sleeve provided
with a forked end and secured to the spindle by a thumb screw. In using the
instrument the free end of the spindle is scized by one hand, and one tooth of the
saw introduced into the groove at the other end. The sleeve is then fixed on the
spindle, so that the forked end projects a certain length beyond the spindle, and
the instrument is turned to the right or left until one of the inner edges of the
fork touches the blade. Afterwards the instrument is applied to the following
tooth and the latter turned to the opposite side for the same distance, that is to
say, until the opposite edge of the fork touches the opposite face of the saw blade.
In this manner all teeth are turned alternately to the right or to the left.

MENTS IN MILLING MACHINERY PARTS OF WHICH IMPROVEMENTS ARE ALSO
APPLICABLE TO WHEEL GEARING WHERE WOODEN COGS OR TEETH ARE USED
°
"
My said Invention is designed to effect improvements in milling machinery
where wooden cogs or teeth are used.
The first part of my Invention consists in forming a spiral groove round the
collar or "hackle" which is attached to the balance irons carrying the upper stone
in milling machinery. This spiral groové is constructed in such a manner that, as
the upper stone is revolved, the walls of the spiral groove tend to throw towards
the circumference of the mill stones the material undergoing pulverization between
said stones, thereby preventing any portion of such material from coming in
contact with the vertical spindles on which the mill stones are mounted. This
arrangement obviates the annoyance hitherto experienced by millers as regards the
leaking and heating caused by the material getting into the annular space formed
between the spindle and the aperture of the lower stone in which it works.
The second part of my Invention has reference to the wooden teeth or cogs of
wheel gearing. These teeth or cogs as hitherto used are found to show considerable
evidence of wear and tear after three years as a rule, when injurious vibration and
serious noise results.
To obviate these defects is the object of this part of my Invention; and to this
end I take a piece of leather or other suitable material which I fold round the
extremity of the cog or tooth, forming thereon a sort of envelope or cap, and secure
same by nails or screws. This improvement admits of the cogs or teeth being used
for a protracted period, facilitates the repairs of same, and prevents the disagreeable
effects arising from noise and vibration as above stated.

This invention has for its object to quench the burning end of partly-consumed
cigars, so that they can be put into the cigar case without danger.
It consists in the application of a conical cap of metal or other incombustible
inaterial, said cap being open at the wide end and closed with a flat or round
bottom at the thin end-By stripping the cap tightly over the burning end of the
cigar the access of air is prevented and therefore the cigar extinguished. The cone
is made of such diameter, that its thin end fits the thinnest and its thick end the.
thickest cigars.

WILLIAM RICHARD WYNNE of 116 High Holborn in the County of Middlesex
Mechanical Engineer A JOINT FOR ELECTRICAL LAMPS TO BE
SUSPENDED AND REMOVED
OCCASIONALLY
This invention is designed to facilitate the occasional application of the electric
light as for instance for illuminating shop windows from without in reflecting
lamps. It consists in the arrangement of parts so that when the joint is made by
attaching to the socket (or cemplement) the removeable part (or supplement) the
circuit of the electric current through the burner is completed and upon the removal
of the supplement the supply of electricity to other lamps from the same source is
not disturbed
An illustration of the joint is given in the annexed drawings in which fig 1 is a
vertical section of the complement and fig 2 a vertical section of the supplement,
figs 3 and 4 representing the faces of the cemplement and supplement respectively
which are to be brought together by suspending the supplement by the bar (shewn
at top of fig 4) upon the hooks one of which is shewn on fig 1. Two wires from
the battery are led to the wedge form pieces secured on springs (shewn as to one in
fig 1). Upon the joint being made the round headed projections from the supplement
press upon these wedge form pieces, and a wire leading to the burner being secured
upon each of these projections the circuit is complete.
To prevent disturbance by the severance of the joint the wedge form pieces
when released from pressure conduct the electricity to a resistance coil or a
secondary battery

HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN
HORSE-COLLARS," a communication to me from abroad by R. Fesch and Company,
of Leipzig, in the kingdom of Saxony,
This invention relates to hames or horse-collars and has for its object to make
them lighter than those hitherto used, and to make them variable in size, in order
to suit different conditions. For this purpose I make the horse-collar of a metallic
skeleton, to the inside of which the bolster is attached by screws. The skeleton
is made of several blades or bands forming a hinge at the top of the collar and a
lock at the bottom. For altering the length of the collar the hinge pieces are
toothed on one side and laid with their toothed portion over a correspondingly
toothed part of the plates which form the sides of the skeleton, a slot being formed
in both parts through which passes an eyebolt having a nut, by which the relative
position of the toothed parts can be fixed. The lock is formed of two hinge pieces,
a toothed strap and a bolt noved by a button and a helical spring enclosed in a
casing. The upper hinges are connected by a bolt, to which is attached an upward
projecting bracket for holding ornaments. The blades forming the sides of the
skeleton may be united by a hinged fishplate having several perforations for
altering the position of the bolt in order to vary the distance between the adjacent
blades.

THOMAS STOKOE LYON of No 203 Strand in the County of Middlesex. AN
IMPROVED BRACKET FOR HOLDING OR SECURING RODS, BANDS, STICKS, AND
OTHER SIMILAR ARTICLES.
The main feature of novelty which forms the subject of this application for patent
consists in pivoting the front portion of the bracket to the back in such manner
that the front portion (which forms a kind of Hap) can have imparted to it a
pendulous or swinging movement only. The front portion is pivoted to the back
sufficiently tight to prevent it having any action of its own so that if moved to any
angle with the back portion it will remain in the exact position left until aguin
moved, so as not to be liable to full or drop.
The invention is capable of being applied to a variety of purposes such as eyelet
brackets for stair-carpet rods, window-curtain bands and rods, as a holder for
billiard cues, fishing rods, umbrellas, whips, walking sticks, and for various other
similar purposes.
It is obvious also that the invention is susceptible of various slight modifications
in detail without departing from its essential features.

straps. Instead of the arm straps being made all in one as they now are, which
causes great inconvenience and discomfort to ladies when wearing low and trans-
parent bodice dresses, as they have to slip the arm out of the arm strap, and tuck
it underneath their corsets. The adjustable arm strap is made to button on both
back and front of the garment, and can be unbuttoned and taken entirely off,
or unbuttoned at the back only, and brought to the front and both the ends
brought from the back to the front buttoned to a button in the middle of the front,
the arm straps being trimmed along the edges form an extra row of trimming along
the front, for evening wear when worn thus-Worn in either way, does away with
the great inconvenience and discomfort of tucking the arm straps of underclothing

marle according to the said invention do not require for their detonation the anvil
ordinarily made in the head of the cartridge, and the manufacture of cartridges
with which the said percussion caps are user is in consequence inuch simplified.
The metallic portions of percussion caps made according to the said invention
consist essentially of two sheet metal cups the one somewhat larger than the other.
The larger one consists of a short cylindrical cup having a bottom concave
internally, the smaller on consists of a nearly similar cup which when inverted
and forced into the other fits therein tightly. The central portion of the bottom
of the smaller is raised internally the projection thus formed constituting the anvil
by which the detonation is effected in the completed percussion cap. The said
smaller cup is pierced with two or other number of holes through which the flash
or fire of the detonated percussion cap is communicated to the cartridge.
The parts of the percussion cap are put together and the manufacture of the
percussion cap completed in the following manner. The charge of detonating
composition is placed in the bottom of the larger cup in the usual way. After the
said composition has become thoroughly dry it is covered with a waterproof
varnish. A disc of tinfoil is introduced into the smaller cup and pressed into closo
contact there with at a press, the said tinfoil being afterwards covered with water-
proof varnish. The smaller cup is forced into its proper place in the larger one by
a press when the manufacture of the percussion cap complete. The detonating

page_text: compound in percussion caps thus made is protected by two layers of waterproof
varnish and a layer of tin foil and is not affected by prolonged exposure to wet
and damp.
The waterproof varnish employed is preferably a solution of shellac in alcohol
or methylated spirit to which a little tar has been added; but other waterproof
varnishes may be used with like effect.

"IMPROVEMENTS IN APPARATUS FOR SIGNALLING ON RAILWAYS."
This Invention has for its object improvements in apparatus for signalling on
railways.
According to my Invention in case of fog when signals may not be visible I give
notice of the state of the signals to the engine-man of an approaching train by
sounding a bell or gong upon his engine.
For this purposo I provide by the side of the line boxes containing moveable
levers or arms which by means of wires similar to distanco signal wires can at
the pleasure of the signalman in a distant cabin be caused to project from
.the box.
Each engine is provided with a finger or moving part which as the engine
passes a box from which the lever has been thrown out comes into contact with
the said lever, and being thereby moved, rings the bell, or sounds the gong,
I provide at each point three of these boxes so that the signalman may by
causing one blow to be struck on the bell or gong intimate that the line is clear
or by two bells that caution is necessary or by three bells that the train is to be
instantly stopped.
I provide also at the signal cabin two large bells or gongs sounding different
notes one for the up and the other for the down line and by blows on one or
other of these the signalman may intimate to the engineman when the line is clear
for him to proceed.
The number of blows on the signalman's bell or gong will indicate the line to
which the signal applies and will be answered by the engineman with the same
number of whistles.

IMPROVEMENTS IN FIREPLACES ESPECIALLY APPLICABLE TO
DOMESTIC AND OTHER STOVES FOR THE PREVENTION OF SMOKE AND THE
ECONOMY OF FUEL. (A communication from Rudolph Müller of Berlin Germany.
The principal object of this Invention is to economise heat and prevent smoke
in domestic, hot houses, and other stoves this Invention is however also applicable
to fire places for other heating and evaporating apparatus.
On the grate of the stove is placed a cast iron fire box or frame open below and
with a hinged fall down door in front; a Bue is formed on each side of the box
and with inlet in front; these flues are continued over the top of the box
entering an uptake formed thereon through many narrow lateral openings.
The air thus coming in contact with the sides and top of the hot fire box becomes
highly heated and in that state combines with the gases arising from the fire.
The stove is fitted with closely fitting door in front and has also a close fitting
lower or ash pan door with adjustable air inlet openings.
The mode of action is as follows. Having opened the stove door and the ash pan
door the inner fall down or firing door is opened and the fuel charged into the fire
box and lighted; the ash pan door and the firing door are then closed while the
outer or stove door is left open so that the air may enter the lateral flues. When
the fuel is burnt out the stove is closed.

"IMPROVEMENTS IN LATHES FOR TURNING AND CUTTING METAL A communi-
cation to me from abroad by Alfred Muir, of the Firm of William Muir and Co
Engineer, at present in the United States of America.
The first part of this invention relates to an improvement in transmitting the
variable speed to the back shaft of lathes.
A wheel on the cone spindle gives
motion to a wheel fixed on the intermediate shaft on which are fixed three or any
number of wheels of different diameters: on the back shaft are fixed three or any
number of wheels of different diameters so placed that the smallest wheel on the
back shaft may be moved into gear with the largest wheel on the intermediate
shaft when the quickest speed is required a larger wheel on the back shaft may
be moved into gear with another wheel on the intermediate shaft when the slowest
speed is required: wheels of suitable diameter on the intermediate and back shafts
transmit the medium speed. The back shaft is fitted so that it may slide
longitudinally to move any one of the wheels fixed on it into or out of gear
with one of the wheels on the intermediate shaft and a suitable retaining catch
is employed to keep the back shaft in the required position.
The second part of the invention relates to the method of traversing the tool
for boring and turning which is carried by the top slide the top slide is traversed
by a rack into which gears a pinion fixed on a shaft driven by a worin and wheel
which can be readily engaged or disengaged the worm shaft is turned by an
automatic ratchet or other feed motion: the tool when cutting or boring is fed by
the ratchet on the worm shaft and when the cut is completed the worin wheel is
released and the pinion shaft is turned by a handle fitted on it and the tool is thus
withdrawn rapidly.

THOMAS ALFRED ADAMSON, of Belfast, in the County of Antrim, Ireland,
Engineer "IMPROVEMENTS IN ROLLER MILLS FOR GRINDING FLOUR, AND
BREAKING, GRANULATING, OR FINE GRINDING GRAIN PRODUCTS, APPLICABLE
ALSO FOR GRINDING GRAIN.
My Invention relates to certain improvements in what are known as roller mills
for grinding flour, namely mills for breaking, granulating, or fine grinding grain
products applicable also for grinding grain.
Hitherto it has been customary to arrange the rollers with smooth, or plain
surfaces, working against each other, or with corrugated surfaces working against
each other.
The improvements which constitute my Invention consist in having one, or more
smooth rollers, working in combination with a fluted roller, or rollers and in the
arrangement thereof.
An example of my Invention consists in arranging "three high" roller mills
with rolls of chilled cast iron, fluted and smooth in combination, driven by
independent belts, the framework of the machine being arranged for the reception
of eccentric revolving bearing carriers, which level, or adjust the rollers one with
the other while in motion. One of the advantages arising from this arrangement
being that any roller with its bearings may be taken out for examination, or
repair without disturbing the other working parts.
The bearings are of extra size and length, and made in phosphor bronze,
lubricated by oil stored in the eccentri bearing carriers which are hollow.
The material to be operated upon is conveyed to a hopper fitted over the rollers
and the feed is regulated by a feed roller and sluice doors.
The rollers are kept to their work, or separated by means of powerful levers,
and scrapers are arranged where necessary and held in position by levers and
weights.
My Invention is applicable to roller mills of two, or more rollers in combination,
driven by belts, gearing and friction.

IMPROVEMENT CONNECTED WITH WINDOW SASH FASTENERS
The object of this invention is a certain improvement in connection with window
sash fasteners whereby the fastener is automatically and securely locked when
closed by a lever pressed against its face or edge under the action of a spring
said lever being easily shifted from the face or edge when the fastener has to be
opened.
For the purpose of our invention we pin or pivot a lever on the base plate of a
fastener or on a separate base plate and fit it so that one end of the lever may bear
against the face or edge of the fastener lever when it is pulled to the front over or
under the tongue piece to close it according to the construction of the fastener.
The opposite end of the automatic lever is acted upon by a spring to force the
other or long end into position the short or tail end being provided with a thumb
piece or button head by which the short end can be pressed inwards and the long
end outwards when the fastener has to be opened the fastener lever being then
permitted to pass in the ordinary manner.
The fastener lever may have a stud or projection on its under surface to force
the automatic lever out of its way while being closed after which the automatic
lever will drop back into its normal position under the action of its spring and
lock the fastener.

THOMAS BLACKHURST of Preston in the County of Lancaster
IN LOOMS FOR WEAVING,"
"IMPROVEMENTS
This invention of improvements in looms for weaving has reference to a novel
construction of dobby or jacquard mechanism in which the lattice barrels are
caused to revolve in stationary bearings and act directly upon the hooks whilst the
general arrangement of working parts is simplified, increased durability resulting.
Two lattice barrels are arranged one on each side of the hooks in the usual position
and are partially rotated simultaneously through the medium of geared wheels at
one end and a catch wheel at the other. A pawl mounted upon a horizontal
rocking lever actuated by a rod connected to a crank on the tappet shaft acts upon
the catch wheel and lattice barrels at each revolution of the tappet shaft, whilst a
vertical rod rising from the inner end of the rocking lever is made to impart the
necessary up and down motion to the knives When the lattice pegs are brought
opposite the hooks they will press upon them thereby causing them to be pushed
clear of the knives as will be well understood.
I prefer to employ in conjunction with the above described arrangement only a
single set of jack levers which I mount at one end on an axis or rod the other end
being connected to the upper heald staves by cords in the usual manner.

FORCING OR PROJECTING WATER OR OTHER LIQUIDS "
The object of these improvements is to utilise exhaust or waste steam or
otherwise steam of a very low pressure for the purpose of producing motive power,
for working bydraulic presses, hoists and other apparatus or for raising or forcing
liquids or projecting water for fire-extinguishing and other analogous purposes.
In carrying out our invention we take the exhaust steam from a steam engine
or low pressure steam from a steam boiler and utilise the same by means of an
arrangement of cones suitably proportioned and similar in construction to the
well-known exhaust injectors for forcing water into an enclosed vessel containing
water and compressed air-the air having been first pumped or otherwise forced
into such vessel at a tension of several atmospheres This pressure of air is
utilised for forcing out the water from such vessel on to a turbine or other suitable
hydraulic motor for producing motive power or for the other purposes before
mentioned.
It will be obvious that the supply of water withdrawn from the vessel must be
kept up by the injector and that thus the compressed air affords a constant and
powerful means of producing and regulating the issuing jet of water and which is
proportioned in velocity to the pressure of the compressed air. For propelling
boats and other vessels, the issuing jet either from the injector or vessel may be
arranged to play direct into the water, or upon the water jet system,

JOHN DOVE ELLSON of Coventry in the County of Warwick. AN IMPROVE-
MENT IN OR CONNECTED WITH THE DRIVING PARTS OF CERTAIN VELOCIPEDES."
"
This Invention refers to velocipedes having more than two wheels and consists
in connecting to the crank a compound arrangement of levers by which driving
arrangement there is no dead centre at any point and all chain or cog wheels aro
dispensed with.
To the crank shaft in addition to the treadle cranks there is connected a com-
pound crank having two arms placed at angles of 45 degrees with each other,
this crank is connected to a similar compound crank on the wheel axle by means
of two vertical links so that when the machine is worked the action will be
similar to that of an engine with four cranks all set at opposite angles to each
other.

JAMES CAMBELL STEVENSON of 20 Layland Street Liverpool in the County of
Lancaster Engineer "AN IMPROVED SELF COMPENSATING PRESSURE REGULATING
APPARATUS FOR GAS WATER OR OTHER FLUIDS OR VAPOURS
33
This invention has for its object an improved self compensating pressure regulating
apparatus by which the flow of fluids into a main or other passage or receptacle is
so regulated as to produce a constant or approximately constant pressure.
According to this invention the flow of Huid takes place through or past a double
valve, or opening controlled by apparatus subject to the action of the fluid in the
main or receptacle, whose pressure is to be regulated. This pressure acts upon a
floating body which can be more or less weighted as required.
In one form of apparatus according to this invention, suitable for regulating the
supply of illuminating gas, a main or chamber is provided with a suitable double
valve the two parts of which are situated respectively above and below a seating
fixed in a diaphragm or partition, the lower side of which is open to the gas supply
and the upper side to the gas outlet. The rod or spindle on which the two parts
of the double valve are placed works at its lower end in a guide, while its upper
extremity is connected to an annular, or other shaped float which can be weighted
to suit the required pressure in the main or chamber. This float acts as or carries
a lid or closure for the upper part of the chamber which lid or closure is subject to
the pressure in the chamber a slight alteration causing it to rise or fall as the case
may be, and to open or close the valve sufficiently to bring the pressure again to
the determined point.
The float is supported in water or other liquid in an annular or other suitably
formed vessel. This vessel is provided with an overflow pipe so that the water can
never rise beyond a certain level and so vary the position to which the float has
been adjusted
It is obvious that apparatus according to my invention may be constructed in
modified forms adapted for use with different fluids and liquids and under different
conditions without departing from the essential features of my invention.

Frankfort on the Main, in the Empire of Germany "IMPROVEMENTS IN APPARATUS
FOR CONSERVING COMESTIBLES." A communication from Heinrich Maehler, trading
under the firm of C. Walther & Co-a person resident at Hof in the Empire of
Germany
The said invention relates to the preservation of any description of comestibles
from decay or mould for a considerable period.
It consists of a lower part or dish of porcelain, earthenware or other suitable
material, and of a cover of glass or other suitable material -
The lower part or dish is supplied with a circular groove or channel to receive
the cover, the floor of the dish receiving the comestiblos being by preference raised
above the level of this channel.
This groove or channel is filled with a liquid such as water, or a mixture of
water and a liquid, such as salicylic acid, preventing decay and corruption.
On the cover is fitted a spring pressed valve which may be operated by the
pressure of the hand to allow the air to enter or escape when the cover is put
down or lifted.
Perishable provisions such as swiss cheese, may be preserved quite fresh in this
Fafe or protector for a period of from 10-15 days without the loss of weight or
flavour, and the cut surface will not get mouldy. This safe or protector is suitable
for households, restaurants, hotels, cheese-warehouses, and similar places and can
be made of any convenient size
IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR EXHAUSTING AIR FROM HAY OR OTHER STACKS

WILLIAM HAIGH of Skipton-in-Craven in the County of York Machine Maker
IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR EXHAUSTING AIR FROM
HAY OR OTHER STACKS
My invention relates to certain improvements for exhausting air from the
interior of Hay or corn stacks and has for its object the construction of portable
apparatus that can be applied to stacks and the air exhausted from the interior
of the stack for the purpose of drying the material when it has been stacked
insufficiently dry.
The manner in which I propose to accomplish my object is somewhat as
follows-l provide a compartment which for all practical purposes is air tight: the
bottom part of the compartiment is curved and the sides thereof parallel to each
other. To the sides are secured journals in which is mounted a shaft, and to this
shaft is secured a wing of sufficient size to fill the compartment in the direction in
which the shaft is mounted, but with clearance to allow the wing to oscillate.
The upper part of the compartment is connected by pipes to the interior of the
stack and is provided with inlet and outlet valves at each side of the wing, so that
when the wing is moved in either direction, air is exhausted from the interior of
the stack.
On reversing or moving the wing in the opposite direction the air exhausted
from the stack is made to pass out of the compartment by the outlet valve in
connection with that side of the wing, and the partial vacuum created in the
compartment on the opposite side of the wing is supplied with air from the stack,
thus by the oscillation of the wing in either direction air is exhausted from the
interior of the stack.

IMPROVEMENTS IN
APPARATUS FOR FILLING SACKS, a communication to me from abroad by Laurent
Laplace and Edouard Laplace, both of Issoudun, France,
This invention has for its object to control the weight of materials to be filled
into sacks.
For this purpose I fix a cylinder to the ceiling of the room into which the
material is to be delivered; around this cylinder are secured suspension rods
serving to hold a balance of any convenient system.
In the platform of this balance is an opening corresponding exactly to the
opening of the cylinder which is hermetically closed by an india-rubber ring.
Inside the cylinder is a disc-valve pivoted on a horizontal shaft projecting
through the cylinder and carrying a crank as well as a pointer.
On the balance and facing the axle of the valve is fixed a stop or abutment.
In the opening of the platform is fixed a ring terminating with a flange and
which serves to hold by means of a belt the sack to be filled.

CHARLES BROTHERS of Duke Street, Manchester Square A NEW OR IMPROVED
COMBINED VENTILATING AND FIRE EXTINGUISHING APPARATUS
This Invention has for its object to afford a simple and effective means for the
almost instantaneous extinction of fire and also to secure good ventilation
My improved apparatus consists of a system of distributing pipes which are
either fitted with suitable jets or perforated in such a manner that in the case of
a fire a large body of water can instantly be thrown upon the flames without
entering the burning building
To effect this a separate series of such distributing pipes is fitted in each room
or floor and each such series is connected to a separate main leading outside.the
building and there connected with the street main or other source of supply
Each of the mains so leading from the building is fitted on the outside with
suitable stop cocks and also with bib cocks or their equivalents for withdrawing
the water from the distributing pipes when not required.
Such distributing pipes when not in use as fire extinguishing apparatus serve to
effectually ventilate the various rooms or floors wherein they are fitted By this
improved arrangement an effectual means for the immediate suppression of fire is
provided without necessitating access to the interior of the building itself while
by providing for emptying the distributing pipes as already mentioned they serve
the purposes of ventilators and all risk of injury to the premises by leakage is
obviated
