WILLIAM EDWIN WILLIAMSON, of Hackney in the County of Middlesex,
Engineer, and EDWARD VORLEY NEW, of Portman Square, in the County of
Middlesex, Architect. IMPROVED MEANS, AND APPARATUS FOR, PREVENTING THE
RADIATION OF HEAT, IN VESSELS CONTAINING HOT WATER, OR OTHER LIQUIDS,
AND IN SOME CASES FOR KEEPING THE LIQUID, OR OTHER CONTENTS, COOL, AND
FOR OTHER SIMILAR PURPOSES "
This Invention has for its object improved means for effecting the retention or
otherwise preventing the radiation of het in vessels containing hot water, tea,
coffee, cocoa, milk, or other liquids, and also especially adapted for keeping the
contents hot or cool as desired, and at an approximately normal temperature: and
consists in an outer and inner vessel, the inner vessel containing the liquid. In
the annular space that is thus formed between the inner and outer or surrounding
case we pack or fill with suitably prepared or ordinary hair or hair felt or other
analogous material.
In a tea or coffee pot or other similar vessel constructed according to our invention
the spout protrudes from the inner vessel and it may also be encased in an outer
tube with a lining of hair felt or other analogous material in a similar manner to
the foregoing.
The lid is also advantageously provided with a chamber for containing a packing
of hair or hair felt or other material and of a size that will fit in the inner vessel
and prevent the escape of the ascending heat.
Our invention is also particularly well adapted to dish-covers, urns, flasks, hot
water jugs or cans, and all other similar articles or vessels.
In the construction of vessels to which our improvements are adapted we in
some cases make the inner vessel of china or earthenware and the outer one of
metal, with the space between them filled with the non-conducting material before
referred to. Or the article may be made entirely of earthenware or other material
and after being packed can be suitably enclosed.
This Invention is also adapted for keeping milk, butter, or other liquids,
substances, or perishable goods cool.

Jeweller "IMPROVEMENTS IN PENHOLDERS'
"
In the use of pens in penholders inconvenience is commonly found to arise from
the pen being exposed to injury when out of use and to the ink carried by it
being given off to the surfaces in which it comes in contact.
To prevent these inconveniences, I provide over the barrel, or portion of the
penholder that carries the nib portion of the writing instrument for ink, another
barrel or cylindrical cover or sleeve and I form on, or apply to, the one barrel, or
the penholder, a stud or projection adapted to take into a groove slot or bayonet
joint, or into suitably formed recesses, or openings, formed in the other barrell so
that by a longitudinal motion and a slight twist, or a partly longitudinal and
partly twisting motion, or other motion adapted to the form of the retaining and
guiding parts, being given to the pen holder the pen and a portion of the holder
will be drawn within, or thrust out from the shelter of the covering barrel, or
sleeve, so as to, alternately present the pen for use in writing, or to withdraw it
under cover when out of use safe from undesirable dispersion of writing fluid and
protect the nib.
AN IMPROVED METHOD OF TREATING PHOSPHATE OF SODA (OR POTASH) TO PRODUCE PHOSPHATE OF LIME

CHARLES HUMFREY of 27 Hough Green in the city and county of Chester AN
IMPROVED METHOD OF TREATING PHOSPHATE OF SODA (OR POTASH) TO PRODUCE
PHOSPHATE OF LIME
For the purposes of my Invention I take quantities of a solution of soda (or
potash) 1, 2, 3, 4 etc and I take equivalent quantities of carbonate of lime say as
chalk A, B, C, D etc. I boil 1 and A together in a vessel Z and allow the
precipitate to settle. I transfer the clear liquor to another vessel Y and boil it
with chalk B which practically exhausts the phosphate of soda (or potash) and
leaves carbonate of soda (or potash) in solution which can be recovered by
evaporation. To A in Z I add dose 2 of phosphate of soda (or potash) boil and
settle, this practically completes the conversion of the carbonate into phosphate of
lime which is removed washed and dried The clear liquor (2) now in Z is
transferred to Y and boiled with B quantity of chalk settled and the clear liquor
transferred to Z and boiled with dose C of chalk after which it is evaporated to
recover the carbonate of soda (or potash) while B in Y gets 3 dose of phosphate of
soda (or potash) and so on.
By using three or more vessels the operation can be repeated as many more times
as there are more vessels.
Instead of boiling the phosphate of soda (or potash) with the carbonate of lime
it may be agitated with it cold in the presence of carbonic acid.
I find that a pressure of about 40 lbs per square inch very much facilitates the
operation

"IMPROVEMENTS IN ATTACHING DOOR KNOBS TO THEIR SPINDLES."
"
I take an ordinary rectangular bar spindle with one knob fixed upon it in the
ordinary way and the other end of the spindle I form circular in section and
wormed with a screw thread upon its surface for some distance. In this circular
portion of the bar I form a longitudinal slot passing through its centre. In the
neck of the second or loose knob I form a screw thread to work over the screw
thread on the spindle, so that this knob may be placed onto the spindle and
screwed up and adjusted to the thickness of the door.
I then pass a screw pin through a hole in the neck of the knob and through
that portion of the slot in the spindle which is opposite thereto and thus into a
sinking in the opposite side of the neck of the knob. By this means the knob is
prevented turning independantly of the spindle and cannot be screwed from off it
without removing the small screw pin. The spindle may be made rectangular
in section its entire length with a screw thread cut upon its angles and the screw
pin may be wormed either at one or both ends.
The spindle may be constructed at both ends as above described.
IMPROVEMENTS IN CENTRIFUGAL CREAM SEPARATORS

ISAAC ALFRED HATTERSLEY of the Aylesbury Dairy Company Limited of
St Petersburgh Place, Bayswater in the County of Middlesex "IMPROVEMENTS
IN CENTRIFUGAL CREAM SEPARATORS "
In centrifugal cream separators, as they are usually constructed, the cream as it
escapes from the revolving drum, is scattered over an extended surface of pan on
which it is apt to become clotted, especially when the cream that is separated is
thick and the temperature is low, and thus its issue from the apparatus at
the proper orifice is much impeded and sometimes entirely arrested, so that
portions of the cream find their way into the discharge passage of the milk and
become mingled therewith. My invention relates to means of avoiding these
difficulties, which I effect in the following manner. I make the upper pan or cover
in which the cream is received from the drum with a bottom convex towards its
middle so that there is a slope in all directions down towards its outer circum-
ference, the convexity however being such that the slope is greater in two opposite
directions towards spouts which are made very wide where they open from the
pan and are gradually narrowed in to their outlets, to which the bottom slope is
continued. In order to prevent clogging of the cream in cold weather, I make the
cover of the cream pan as a double casing and cause warm water to circulate
through it, or from time to time I blow a little steam through it, so that the
radiation from its under surface keeps the cream passing along the surface of the
pan below in a sufficiently fluid condition.
IMPROVEMENTS IN ELECTRODES USED IN THE ELECTRO AMALGAMATION OF GOLD AND SILVER AND OTHER ORES

RICHARD BARKER the younger of Moriatta, Sunderland Road Forest Hill in the
County of Surrey Electrical Engineer IMPROVEMENTS IN ELECTRODES USED IN
THE ELECTRO AMALGAMATION OF GOLD AND SILVER AND OTHER ORES
This invention relates to improvements in the Electrodes used in Electro
Amalgamation by providing special metals for that purpose. These improvements
are specially applicable to the prevention of the accumulation of oxygen and other
gases or substances on the Electrodes used in Electro Amalgamation
By my invention the great loss of time and efficiency in working with the
ordinary electrodes which absorb oxygen (produced by the decomposition of the
water) is entirely prevented, as the metals I use have no affinity for oxygen
The metals at present used in Electro Amalgamation rapidly oxidize in water
under the Electric Current, and so become foul. This necessitates constant
watchfulness and cleaning. If this is neglected through inattention or want of
proper electrical knowledge the current ceases to flow, the process is at at a stand
still (although the ore is travelling over the riffle table all the time) and a
consequent loss of gold and silver and other ores is the result. By the use of
metals proposed by me this oxidation cannot take place, and the loss in gold and
silver caused by the cessation of the Electric Current is entirely avoided.
According to my invention I affix a film or layer of platinum gold or aluminium
on the under or exit side of an electrode and on the top or ingress of the
complimentary electrode, deposited thereon by the well known methods used in
Electro Plating, or rivetted thereto or screwed to or fixed in any suitable manner
so as to form a film or layer of Platinum, gold or aluminium on the outside of the
baser metal. I also use an alloy of aluminium and Copper in such suitable
proportions as in practice may be found most advantageous and economical for
attaining the object in view
AN IMPROVED DEVICE OR APPARATUS UPON WHICH TO HANG COATS OR OTHER LIKE ARTICLES

ALFRED ELLIOT of 42 Aden Grove Stoke Newington in the County of
Middlesex, "AN IMPROVED DEVICE OR APPARATUS UPON WHICH TO HANG COATS
OR OTHER LIKE ARTICLES
"
The object of my invention is to construct a device or apparatus upon which a
coat or other like article may be readily hung or suspended as though it were
actually upon a person whereby if it is wet or dirty it can be readily dried or
cleaned; my apparatus also has the advantage of keeping the coat or other article
in shape.
My apparatus consists essentially of a pair of arms or pegs hinged to a central
block and provided with springs to throw up the said arms to a convenient height
to enable the arm holes of the coat or other garment to be readily hung upon them.
The weight of the garment immediately lowers the arms of the apparatus into a
horizontal or approximately horizontal position whereby the back of the garment
is stretched like it is on the back of a person. As soon as the garment is removed
the springs again throw up the arms of the apparatus. The said arms are by
preference curved to correspond with the shape of the coat and are fitted with
knobs or like contrivances at the ends so as the better to hold the arm holes.
The springs may be of any form and fitted in any manner thought most suitable.
One way which I find to answer well is to employ flat metallic springs between the
centre block and the arms the springs having rounded ends to diminish friction.
The apparatus, one or more of them, may be fitted to a back board on a wall or
to a stand or pedestal which if thought desirable may be capable of revolving; or
they may be otherwise placed according to circumstances

ANTHONY RICHARD CRAGG of Hereford in the County of Hereford, Land
Surveyor. "IMPROVEMENTS IN SURVEYORS' PLOTTING AND MEASURING SCALES"
The object of this Invention is to facilitate the Plotting or laying down of offsets
on both sides of the line when Plotting a Survey without having to remove the
scale and thus to insure greater accuracy and expedite the work and it consists in
the employment of an Instrument constructed as follows.
The Chain Line Scale is raised about half an inch above the paper on two solid
end supports A small groove is in the centre of this scale to allow two narrow
plates to pass therethrough the one to contain a fine needle wire indicator to read
off the required length of the Chain line the other to secure a finger plate used to
propel a T shaped sliding plate about one inch in length supporting a shoe which
secures an offset scale at right angles to the chain line scale This T shaped plate
is supported on a grooved triangular bar fixed into the before mentioned end
supports
The Chain line scale and the triangular bar are bevilled to a centre about one
sixth of an inch above the paper being two acute angles to the Chain line scale
and forming a triangle above the Chain line so as not to obstruct the sight when
reading the offset scales.
A fine needle wire is drawn between the two end supports just above the paper
and a small pin is fixed exactly under the commencement of the Chain line scale
so as to slightly penetrate the paper. This pin being fixed at the commencement
of the Chain line and the fine wire placed over and along such line the scale is
thus fixed in position and the draughtsman lays down his survey marking off his
offsets on each side of the line.
Both the Chain line scale and the offset scale are marked off into feot and
inches or chains and links, the offset scale being marked off each way from its
centre.
The Scales are made moveable and are held in position by a small pin or screw
at each end, so that any desired scale may be applied to the instrument.
A small adjusting screw may be attached to the end of the wire line to tighten
it up when required.

JAMES MARLOW MARRIOTT VINEY of Birmingham in the County of Warwick
"IMPROVEMENTS IN TRICYCLES OR OTHER LIKE VELOCIPEDES WORKED BY THE-FEET
WHILE IN A SITTING OR RECUMBENT POSITION
"
This invention is designed to give a more comfortable action in tricycles and
other mechanisms worked by the feet and to substitute an oscillating or pendulum
motion for a rotary. It will also if desirable enable different speeds to be adopted,
one for up hill and the other for a level or down hill.
It consists in fixing the treadles to the bottoms of pendulum rods and in placing
on steel or other discs on the pendulum rods spring catches or pawls which catch
on to a ratchet toothed, milled, or other wheel.
If ratchets be attached at different points of the pendulous rods by using one
or another ratchet throwing the other out of gear greater speed can be obtained at
the expense of power, or greater power at the expense of speed.
The ratchet or other wheel is connected to the driving axle or driving wheel by
gearing or wrapping connectors such as straps, chains or the like-but I prefer
gearing. In place of altering the position of the pawls to increase or lessen the
speed relatively to the power differential gearing can be employed. The discs
above mentioned can be placed at the top of the rods and one be concave or
fastened or fitted to a concave surface and the other to a convex surface. The
discs thus fit on opposite sides of the milled wheel.
AN IMPROVED MACHINE OR APPARATUS FOR CUTTING CORKS, EITHER CONED OR CYLINDRICAL.

JAMES HIX of 8 Station Road, Battersea, in the County of Surrey, Engineer.
AN IMPROVED MACHINE OR APPARATUS FOR CUTTING CORKS, EITHER CONED OR
CYLINDRICAL.
In the construction of my machine for cutting cylindrical corks I use a bed
plate of iron or other suitable material upon which are fitted.-Two or more
bearings carrying a hollow spindle with a tool or cutter at its extremity on
which is a pulley to drive the said spindle pieces of metal to guide the pieces of
cork to be operated upon the centre of the guide being parallel with the tool or
cutter and a lever which propels the cork through the guide and is worked either
by hand or automatically by a screw from beneath the end of the lever working
in the guide being so constructed that it can be stopped and placed in any position
in the guide if required without stopping the feed screw it also stops automatically
at the end of the feed. I fit to the guide small knives for the purpose of slicing
the cork longitudinally in order to ease the tool or cutter of the debris.-The
tool or cutter is made of steel tube or other suitable metal sharpened at its
extremity at a slight angle and is resharpened when necessary whilst revolving in
its place by means of a whetstone fitted to the machine actuated upon automatically
or otherwise-In the use of a long guide for holding a number of corks I fasten to
the centre a head piece with rollers working under a spring in order to avoid the
corks bulging up by pressure of the feeding apparatus. In order to avoid friction
upon the tool or cutter I fit either on the tool or cutter or hollow spindle a
circular piece of metal coned towards the tool or cutter and is also recessed for
the purposes of containing water.-My machine for cutting coned corks is
constructed in the same manner as the machine just described with the exception
of the tool or cutter and slicing knives which are constructed as follows-The tool
or cutter is made of two or more pieces of metal forming a circle capable of
adjustment for decreasing their diameter when revolving around the cutter I place

page_text: a ring of metal working on a bearing against arms (four by preference) of the lever
thus in the action of feeding the corks it will be observed the lever also closes the
cutting tool. The slicing knives are placed in a bearing square by preference a
spring is placed between the head of the knife and its bearing point they are
actuated upon by arms of the lever placed at an angle with the guide and so give
them a piston action for slicing deeper as the cork is fed by the lever.
IMPROVEMENTS IN DETACHING GEAR FOR SHIPS BOATS, CARGO SLINGS-ROLLING STOCK COUPLINGS AND ALL PURPOSES TO WHICH INSTANTANEOUS RELEASING MAY BE ADVANTAGEOUS

IMPROVEMENTS IN DETACHING GEAR FOR SHIPS BOATS, CARGO SLINGS-ROLLING
STOCK COUPLINGS AND ALL PURPOSES TO WHICH INSTANTANEOUS RELEASING MAY
BE ADVANTAGEOUS
My invention is particularly applicable to the instantaneous releasing of ships
boats. and consists of a lipped pocket. enclosing a weighted hook-the pocket being
formed upon the end of a rod or bolt which it is proposed to secure to the keel of
the boat. the attachment may however be made in any other suitable manner
The end of the bolt which carries the pocket is formed similarly to the forked
end of An Engine Connecting Rod-in order to admit of the weighted hook being
pivotted between its jaws.
The upper end of the weighted hook is curved to a radius struck from a centre
near that of the pivot and the lower end which is extended below the pivot upon
the opposite side of the rod or bolt. is weighted. The object of the weight upon
the end of the lever is to effectually cause the hook to close in upon the link or
shackle after it has been dropped into the pocket
The object of the pocket (which is curved inside to the radius of the link it has
to receive) is to form an unmistakeable guide for the admission of the link to the
desired position and is so designed that it forms a V shaped entrance between its
side and the outer curve of the hook so that the shackle when being dropped opens
the look for the desired time and the weight which during this operation has been
momentarily raised during the passage of the link to its seat immediately falls and
causes the hook to secure its load.
The manner in which I " let go" is by pulling a trigger line attached to a staple
on the weighted end of the lever, and by thus taking up the pressure, the hooked
end is correspondingly thrown out making way for instantaneous detachment.

HERBERT JOHN HADDAN, of Kensington, Middlesex IMPROVEMENTS IN MUFFS
a communication to me from abroad by François Hüsgen, of Bruxelles, Belgium.
This invention has for its object to render muffs more practical by making them
lighter and handier so as to cause less inconvenience when used and also to prevent
their loosing their proper shape by constant use.
For this purpose I replace the material hitherto used for filling the interior of
muffs, such as wool, feathers, wadding, by an air reservoir made of indiarubber.
This air reservoir consists of two concentrical cylinders joined together at both
ends and provided with an opening to which is attached a small tube serving as
an ingress or egress for the air.
This tube is closed by means of an obturator or plug made of metal, wood, gutta-
percha or any other suitable material.
When the muff is to be used the reservoir is inflated by blowing air into it
through the tube after which the latter is closed by the plug.
This air reservoir may be applied to muffs of all kinds and shapes without
interfering with the requirements of fashion.

For this purpose I first mould the body of the label or tablet in clay or similar
material on which whilst in a plastic state I stamp or otherwise form the letters
and words of the inscription which the said label or tablet is to bear; this when
used for garden purposes would be the name of a tree or plant and when for indoors
would indicate the name or quantity of goods of any kind. The back of the label
or tablet has formed in it a groove or recess by which it is slid on and secured
to a metal stand or it may be provided with holes to allow of attachment to
objects by means of string or wire. When the label is completely formed it is
glazed and baked in the manner of earthenware goods generally.

"IMPROVEMENTS IN
My Invention relates to improvements in the class of tricycles known as the
Humber," wherein the rider straddles a seat mounted on a back bone in the same
manner as with a bicycle. It has been found with the ordinary steering arrange-
ment that in travelling over an uneven road the rider is apt to momentarily lose
control over the vehicle by reason of one of the wheels coming in contact with a
projection which causes the vehicle to swerve from its true course and is
consequently liable to lead to serious accidents.
The object of this Invention is to provide this class of machine with steering
gear which will enable the rider readily to guide the vehicle and maintain it in its
true course and thus avoid the objections above referred to. To this end I
interpose between the steering handle and the front axle either a screw rod
connected as hereafter described with the steering axis or centre, or interpose
between the steering axis and the steering handle an arrangement of bevel gear.
In the first instance I employ a horizontal screw shaft with a nut travelling thereon
and connected to a lever on the steering centre or axis by a link, or instead of a
single screw I may employ a screw shaft having right and left handed screws upon
it each provided with travelling nuts and connected to the ends of a double ended
lever.

"IMPROVE-
This Invention relates to an improved self cocking central fire sporting gun.
The Invention consists essentially in the construction, combination, and
arrangement of the lock mechanism whereby the gun is cocked by the motion of
the barrels when the breech end is thrown up for the purpose of loading. The
mechanism of the lock is reduced to the simplest possible form, there being but
three parts, viz, the main-spring, the combined hammer and tumbler and the sear,
carried by the lock plate.
The lock plate is prolonged forwards along the side of the action as far as the
joint on which the barrels rock and encloses a chamber provided within the action
for an arm which is rigidly fixed to the fore end of the stock and projects
rearwards into the said chamber wherein it rises and falls with the breech end of
the barrels.
The tumbler is provided with a forward extension or tail piece under which the
said arın takes in such manner that as the latter rises, the hammer is thereby
thrown back to full cock.
In order that this self cocking action may be effected without the aid of any
other part or spring as is at present the case, the longest branch of the main
spring engages in a notch in the tumbler whilst its shorter branch bears upon the
sear just in rear of its pivot.

"
The object of my invention is to increase the efficiency of telephones, and the
distance to which messages may be transmitted.
It being the fact that the intensity of the sound produced by the vibration of a
diaphragm depends upon the density of the air in which such vibration occurs;
my invention consists, essentially, in causing the vibrations or sounds arising from
the transmission of telephonic messages, to take place in enclosed cylinders
containing air or gas of greater density and pressure than that of the ordinary
atmosphere; and such increased density is obtained by using dense gases or
compressed air for the purpose.
Intermediately between the transmitter telephone and the receiver or transmittee
telephone, I place two telephones in a cylinder containing air or gas under pressure.
The cylinder is made sufficiently strong to sustain the necessary pressure, The
sound emitted by the enclosed telephone which receives the message is louder than
it would be under ordinary circumstances, and such increased sound is received
by the second telephone (in the cylinder). From this second telephone the
sound is transmitted to the receiver or transmittee; or it may be carried to a
second cylinder or a succession of cylinders, each containing a pair of telephones in
a dense atmosphere, in order to transmit telephonic messages to a greater distance
than hitherto has been found practicable.

My Invention is intended to simplify the use of gas burners for cooking and
similar purposes and to prevent waste of gas.
I propose to accomplish this by attaching to the supply tap a lever, in such a
way that when the pot or vessel is put on the burner it turns on the gas supply,
and keeps it so turned on as long as it remains in situ. When the lever is relieved
from the weight of the vessel it rises automatically and is restored to its place
by the action of a spring, a counter weight, or otherwise, and the gas is thus
turned off.

This invention consists in a continuous Process for the metallic coating of wires
by galvano plastic means
A Continuous process has heretofore been carried on in a somewhat similar way
but by the use of molten metal baths and whenever galvano plastic means were
used the wires were placed in the bath and left there till a sufficient coating of
metal had been formed
By my continuous galvano-plastic process the wires pass through the metal bath
over rollers and between anodes of nickel or other suitable plating material
arranged on supports that can be raised or lowered in the bath and which are
connected with the battery in the usual manner. The wires pass through the
bath without interruption in a continuous movement the velocity of the motion
and the draft and length of the vessel containing the metal bath being so arranged
that the wire is sufficiently coated with metal while passing through the bath It
is evident that the coating with metal of a given quantity of wire can hereby be
more quickly effected than heretofore the process offers therefore greater efficiency
besides giving a more even coating and thus not only a greater quantity of wire is
prepared in a given time but also of better quality
The arrangements for passing the wires through the bath may remain as
heretofore only for the molten metal bath is substituted a vessel containing the
galvanic bath through which a sereis of wires pass continuously in one direction
and leave the bath in a prepared state when they are wound up on rollers.

HENRY SMITH of Southampton Street, in the County of Middlesex IMPROVE-
MENTS IN APPARATUS FOR MARKING OUT TENNIS COURTS
This invention refers more particularly to devices for marking out and measuring
spaces or "Courts" for lawn tennis and similar games-although it may be used
for other purposes-The improvements relate to a dial affording the means of
recording the distances measured combined with an apparatus for marking right
angled off sets and a folding frame holding a colour reservoir intended to feed a
travelling wheel and so mark the lines required, and when said wheel is travelling
cause the recording device to move and show the distance travelled and indicate
the position at which the right angled off sets are to set out-The improvements
are conveniently performed by placing a peg on the axle of the travelling (and
marking) wheel said peg gearing into the teeth on the underside of dial said dial
having on it certain marked distances, to which the size of said wheel and its teeth
are proportioned. The apparatus for marking right angles consists of a syringe
arranged with its nozzle at right angles to the travelling wheel

"IMPROVE-
This invention consists in placing in the sunken vessel by means of divers,
inflatable bags formed of approximately the same shape as the vacant spaces in said
vessel. These can be introduced very easily in case of necessity even by cutting
holes in the hull and inserting the bags. When the bags are inserted in said spaces,
they are inflated by means of an air pumping apparatus on a pontoon or other
vessel on the surface and pipes connecting with the nozzles of the bags. Each of
these nozzles has a cock to turn off or on. The mode of application is as follows.
The bags being placed in position, their nozzles are connected by pipes to the air
pumping apparatus, and the pump set to work. If several are being inflated at
once, their pipes can be led to an accumulator on the floating vessel weighted to a
given pressure.
When the. bags are inflated, no more air is forced in, as the
accumulator or air pump as the case may be, having a safety valve or self acting
pressure stop of any ordinary construction, stops the further addition of air.
diver now turns off the cocks, and unscrews the pipes, or if all are attached at once,
inflation goes on till the vessel' rises. In practice however it will usually be found
Dost convenient, to inflate a few at a time, and to prevent straining the vessel,
these should be scattered about different parts of the length of the vessel, or so
placed as not to put a heavy strain on the vessel, while the remainder are being
inHated. In passenger vessels bags of this sort could be carried strapped up
to the underside of the decks in various parts, so that in case of danger of
foundering from springing a leak, they could be inflated and thus prevent the water
entering.

EDWARD LUMLEY, of the City and State of New York, United States of America,
"IMPROVEMENTS IN ELECTRIC LAMPS OR LIGHTING APPARATUS
"
This invention has reference to an improved electric lamp based on the principle
of incandescence, and the said invention consists of an electric vacuum lamp in
which the carbon conductor is secured into flattened and spirally-coiled ends of the
metallic conducting-wires and cemented thereto.
In carrying the said invention into practice I provide a glass bulb in which a
high vacuum is established by any approved apparatus. Through the glass-sealed
neck of the said bulb are passed the metallic conducting wires which support the
carbon conductor that forms the light-giving part of the lamp when the current is
passed through the same. Any carbonized filament may be employed for the
carbon conductor, the ends of which are secured into sockets formed at the interior
ends of the conducting-wires, said sockets being obtained by first flattening and
then spirally coiling the ends of these wires. A cement made of lamp-black or
finely ground plumbago is laid with a brush over the sockets so as to fill up the
interstices between the spiral coils of the sockets and form an intimate connection
between the carbon conductor and the terminal sockets of the wires. In this
manner a large contact surface between the conducting wires and the light giving
portion of the lamp is obtained, which has the advantage that the carbon conductor
is quickly and easily attached to the wires without requiring any extra plating or
carbonizing of the contact points, and that it is not liable to break at the points of
connection therewith.
IMPROVEMENTS IN GAS METERS

THOMAS GARDINER MARSH of Oldham in the County of Lancaster Gas Engineer
"IMPROVEMENTS IN GAS METERS."
My invention relates to wet gas meters and the object of my Invention is to
obtain an accurate measurement of the gas in spite of any alteration in the level of
the water in the meter.
In performing my Invention I mount the drum in suitable floating bearings
which with the drum are free to float in and rise and fall with the water through
which the drum moves.
The ordinary wet gas meter does not measure accurately unless the water level
is constant and this is difficult to maintain through evaporation and from other
causes: by my improvements the drum is always supported at an uniform depth
in the water and in this manner no alteration in the size of the measuring chamber
takes place even if the water in the meter is diminished or increased.
IMPROVEMENTS IN LAWN TENNIS AND RACKET BATS

"IMPROVEMENTS IN LAWN TENNIS AND RACKET BATS."
According to my invention I place or introduce in Teunis or racket bats a metal
weight preferably but not necessarily in the form of a ring, for example it might
be of oval shape in a line with the centre of the handle or in such manner as to
place the weight in a position to suit the player or to balance the curve in the
racket. The metal weight may be made in segments holted together or may be a
"jumped" ring adjustable by means of a screw or with a band of metal round it
or other convenient means so as to tighten or adjust the gut equally and finally at
the will of the player. The weight may be hollow so as to be filled with shot or
other substance to the required weight and the weight may be made in combi-
nation with rubber ivory or any elastic substance. The handle and frame of
the bat may thus be made light and the weight be placed or adjusted exactly
where it is required. Rackets or Tennis bats strung in this way will give increased
strength and lasting qualities to the bat.
The weight may take the form of a chain, to be tightened by swivels on screws
or otherwise. I prefer the string to be endless and to pass alternately through the
weight or through perforations in same and the side of the bat and the boring of
the bat for the strings or for the reception of same is to be in such manner that
the front and back strings shall be parallel with each other leaving space between
for the adjustable screw in connection with the ring. The screw may be a pin
with holes bored transversely for adjustment with a bradawl lever or other suitable
instrument.
In some cases I dispense with the boring altogether and then carry the string
round the outside rim of the bat and in this way I am able to reduce the thickness
of the bat and use lighter material
CERTAIN IMPROVEMENTS IN LAMPS FOR VELOCIPEDES, AND IN THE MODE OF CONNECTING THE SAME TO THE SHAFTS THEREOF

HENRY MARKHAM and THOMAS BRETTELL both of Birmingham in the County
of Warwick CERTAIN IMPROVEMENTS IN LAMPS FOR VELOCIPEDES, AND IN THE
MODE OF CONNECTING THE SAME TO THE SHAFTS THEREOF
"
Our Invention consists of the improvements herein after described in lamps for
velocipedes, and which are chiefly suspended to the shaft or axis
We will describe our Invention as applied to a Bicycle lamp
This class of lamp has hitherto been suspended to the shaft or axis by a barrel
connected to the upper portion of the lamp the interior of which is fitted with
leather washers in some cases a leather lining for preventing a noise, but by the
constant friction the said leathers soon wear out and a difficulty has arisen in
replacing them
We dispense entirely with the leathers by constructing a loose barrel the interior
of which corresponds to the shaft or axis, to arrange this upon the same it is
provided with a hinge for opening, and when adjusted securely held by a screw and
thumb piece by compressing the shaft or axis This barrel has also a check or seat
at each end, and the barrel of the lamp (which is divisible) being of the same
length as the barrel, fixed upon the shaft or axis, and provided with a collar at
each end corresponding to the check or seats above described and by means of
which the lamp is suspended
To that part of the barrel affixed to the top of the body of the lamp we
construct a slot, and to the door of the same (which is detached) a tongue piece, so
that when placed in the slot and the door and body compressed become secure by
engaging in the spring at the base of the lamp as bituerto-to facilitate the
adjustment we have two lip pieces one on the section barrel of the door, and the
other on the section barrel of the body for the thumb and finger It will be
perceived that the jointing or hinging is here dispensed with but we do not limit
ourselves as in some cases we may use hinges.

page_text: To the burners of lamps a spindle with toothed wheels is employed for the
raising and lowering of the wick, but by the vibration of the vehicle this is
frequently moved either to increase the light or diminish or extinguish ;-to
prevent this we employ a screwed rod with milled button (or its equivalent) at
the back by preference passing into the body of the lamp and against the spindle,
thus securing it in the desired position

JAMES CAMERON of Lauriston, Inchture, in the County of Perth, North Britain
"IMPROVEMENTS IN TRICYCLES, OR LIKE MACHINES"
This invention has especial reference to the mechanism by which tricycles or
like machines are driven and it consists in placing upon the driving shaft of the
tricycle and between the wheels a chain pinion, passing over and gearing with
which is a chain driven from a larger chain wheel which is carried upon a rotating
shaft. Upon the last mentioned shaft are fitted two ratchet wheels with the teeth
of which two spring pawls pivoted to the treadles are engaged when pressure upon
the same is brought to bear. For the purpose of returning the treadles to their
normal position they may be provided with springs, counterweights, or other
equivalent means and they may, if found necessary, be coupled together by a rigid
bar or other equivalent means so as to enable an alternating motion to be given
to them.
IMPROVEMENTS IN FIRE ARMS AND APPARATUS FOR TESTING THEM

HORATIO FREDERICK PHILLIPS of Broadway Works, in the City of Westminster,
"IMPROVEMENTS IN FIRE ARMS AND APPARATUS FOR TESTING THEM
"
My invention has reference to breech loading small arms of the kind technically
called "hammerless," and relates to means whereby the movement of the barrels in
relation to the stocks that occurs in the act of opening or exposing the breech ends
of the barrels is caused to effect cocking of the hammers
My invention may be applied to single or double barrelled guns. I will, for
clearness, describe it as applied to the lock of one barrel in a double barrelled gun.
I employ a lever of the second order that I will call a cocking lever, whose
pivot or fulcrum is in the lock plate or frame. This lever is operated by a
pivotted plate or lever which is brought into action when the barrels are turned on
the joint or body pin to expose the barrel ends. The cocking lever is provided
with a projection which when the said lever is operated by the above named
movement of the barrels acts directly against and thereby compresses the main
spring and cocks the hammer. The "fore end iron" is recessed, and is furnished
with a pivotted block so formed and arranged that it will allow of the "fore end
iron" being placed in position under the barrels, or removed when the hammer is
down, but when in place will bear against the fore end of the pivotted plate or
lever so as to ensure operating it to cock the gun on opening the breech.
It will be understood that there is a separate cocking lever and pivotted plate or
lever to actuate the same for each hammer in a double barrelled gun.
I have found by experiment that when one of the barrels of a double barrelled
rifle is discharged, such barrel besides becoming temporarily expanded or increased
slightly in diameter is also somewhat shortened, thus producing a temporary
curvature of both barrels-and I consider it due to this circumstance that it has
not heretofore been found practicable to obtain reliable results when firing double
barrelled rifles from mechanical rests. Now, according to my invention, with a
view to enabling this to be done I use a stand with Y shaped rests, to support the
barrels, and I provide a cross piece or bar of any suitable form, which by suitable
springs I cause to press evenly against the upper portions of the two barrels, so as
to hold them in proper position whilst a discharge takes place but to permit of the
temporary slight change of form due to expansion as above set forth
