HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN
APPARATUS FOR DRESSING LITHOGRAPHIC STONES AND SIMILAR OBJECTS," a com-
munication to me from abroad by Carl Gottlieb Röder, of Leipzig, Germany,
This invention has for its object to dress the surface of lithographic stones by
means of revolving discs, without allowing the latter to wear out unequally, which
drawback results from the fact, that in ordinary machines the grinding discs
describe continually the same path.
The invention consists in imparting to the grinding disc a cycloidal motion by
mounting it on a vertical shaft spindle, the upper end of which is screwed into a
tooth-wheel gearing into a internally toothed fixed ring and mounted on the
vertical crank pin of a disc crank whose shaft receives its motion from a horizontal
driving shaft by means of a pair of bevel wheels.
The invention further consists in an automatically acting sand and water sup-
plying apparatus, which is connected with the driving mechanism in such a manner,
that water and sand can only reach those parts of the stone which are not covered
by the grinding disc, and the sand is strewn on the stone in two or more intervals
during every revolution. This is preferably effected by providing the disc crank
with two concentric grooves open towards the top, one for the reception of sand
and the other for the reception of water.

My invention relates to those machines known as Howard and Bullough's cold
air sizing machines and the object of my improvement is to size a greater quantity
of yarn in a given time than can be done by machines now in use, to regulate the
supply of size and keep it from clotting and to prevent the yarns adhering
together.
I place near the size trough an additional trough in which is an agitator to stir
the size and a float connected to a valve in the pipe that supplies the size, so that
when the trough is sufficiently full the supply is cut off and as the level of the size
in the trough falls the valve is opened and more size supplied. I supply steam to
this trough to boil the size. I form the auxiliary trough with a curved or rounded
bottom to avoid the settlement of the size. In order to dry the yarn rapidly I place
Dear the delivery end of the machine a cylinder which I heat by steam and round
which I pass the yarn and thereby dry it quickly and so prevent it adhering
together or forming tape.'

The object of this invention is a means whereby temporary partitions or screens
may be formed at will, in buildings out in the open or on board ship but is
particularly applicable to class rooms where it is desired to separate the different
classes.
According to the first part of this invention I hinge to the backs of the forms or
seats one or more flaps composed of wood or other suitable material capable of
being turned up in a vertical position the said flap or flaps is or are kept in such
position by means of pins bolts or other suitable means. It will be seen that a
class room for example may be formed into a number of separate compartments
by turning up some or all of the flaps.

According to the second part of this invention I hinge the flaps in the floor this
propose to effect by having boxes or recesses (with covers) therein in which the
flaps fold and when such flaps are put in-position they form the screens or partitions.
The recesses or boxes being covered over so as to be flush with the flooring or
according to this part of my said invention instead of having Baps folding in the
said boxes or recesses. I may hinge a folding standard or standards at one or both
ends of the said boxes or recesses and fix between such standards a suitable flexible
material so that when the said standards are turned up in a vertical position a
partition or partitions is or are formed. The aforesaid boxes may be made portable

Commissioners of Patents on the 9th November 1882.
WILLIAM SMITH of Aberdeen in the County of Aberdeen North Britain, Civil
Engineer and Resident Harbour Engineer, "IMPROVEMENTS IN OR CONNECTED
WITH HYDRAULIC ACCUMULATORS."
This Invention has for its object to dispense with the weight or load on the rams
of hydraulic accumulators, and it consists in the substitution therefor of the elastic
pressure of air or of springs equilibrated or made uniform by means of levers. The
ram or plunger of the accumulator has friction pulleys on the top, on which bear
the ends of a pair of levers whose fulcrum pins are centred in line with the top of
the friction pulley when the plunger is wholly in the cylinder. The opposite ends
of the levers are coupled by means of connecting rods with the pistons or plungers
of two air cylinders which communicate with a reservoir containing air pumped to
a high pressure. The arrangement of the levers in relation to the hydraulic plunger
or ram, is such that the effective leverage at which the ram acts, increases in the
same proportion as the compression of the air by the air pistons so that the load on
the accumulator shall remain constant. The high pressure of the air is produced
by means of air pumps driven by hand or by the pumping engines. In the latter
case a valve connected with the hydraulic pipe or cylinder regulates the pressure
by allowing the fluid to escape when a certain pressure is exceeded into a small
cylinder wherein it acts on a piston and thereby causes the driving belt of the air
pumps to be shifted so as to arrest the supply of air. If the elastic pressure of
springs equilibrated by means of levers is to be employed in lieu of air, the
hydraulic cylinder, plunger, and levers are arranged as described above, but the air
reservoir is dispensed with and the air cylinders are filled with water or other fluid
which is forced into a series of tubes containing pistons pressed by helical springs
against the fluid, the springs being adjusted so that their pressure increases as the
effective leverage during the outward stroke of the hydraulic plunger.

In carrying out my invention I take the leaves of various kinds of plants or trees,
and subject them to suitable treatment whereby the fleshy part of the leaves are
removed, the "skeleton" only remaining; the "skeleton" is then dried and in this
condition it is ready to be employed in the manufacture or ornamentation of various
articles such as those hereinbefore mentioned.
For example, in the manufacture of a fancy box, a leaf or leaves treated as
herein before described is or are taken and cut to the size and shape required and
placed over the surface or part to be ornamented and attached thereto by glue or
otherwise, the interstices are then filled in if required with-suitable colors and the
box finished in the usual manner. Or box frames may be wholly made from
skeleton leaves in combination with suitable lining.
The application of my invention to other purposes will be understood without
further description.

This Invention, which relates to improvements in purses for holding money
tobacco and other articles, has for its object to construct such purses froin one
piece of leather or analogous material and without a seam the purse being at the
same time furnished with a cover lock,
In carrying out the Invention the piece of leather or other material is passed
through an apparatus whereby it is made into a round or oval bag shape and the
edge is then pressed into an oval frame and clenched or corded. An oval arched
cover of metal wood or equivalent material is fastened to this frame by a hinge
and opposite to the hinge a lock is fastened. The space caused by the arch of the
cover is closed by an inner. lock plate and is intended to contain the money or
other article. The lock is opened by drawing out a button or stud which permits
the inner lock plate to be jerked or forced up by means of a spring fastened to the
hinge.
The shape of the purse as well as the cover lock affords a complete view of the
contents when open and the space occupied by the purse is the smallest porsible
relatively with purses capable of holding the same amount or number of contents.

Lanark, North Britain, "IMPROVEMENTS IN APPLIANCES FOR COUPLING AND
UNCOUPLING RAILWAY CARRIAGES, TRUCKS, AND OTHER VEHICLES
"
This invention, which relates to improvements in the coupling or uncoupling of
railway carriages, trucks, vans, or other vehicles, has for its object to enable railway
or other vehicles to automatically. couple themselves together as they approach each
other and to enable them to be disconnected or uncoupled either automatically or
non-automatically without requiring a man to place himself between railway or
other vehicles where coupling or uncoupling them as is the present practice.
The Invention consists in providing at the central or other suitable part, at the
ends of each railway vehicle, one or more pairs of clutches. One clutch or one or
more pairs of clutches, the solid projection or projections on any one of which
enter into the hollow receptacle or receptacles of the clutch of the adjoining vehicle
and wherein after having so entered they are retained by a pin or catch holding
the solid within the hollow part thereof. This pin or catch of each such clutch is
mounted upon a shaft which extends out to one or both sides of the vehicle, and is
there provided with a counter weight, a screw wedge, or the equivalent thereof
which keeps the pins or catches of the clutches in that position whereby they are
held together.
Instead of using double clutches of the construction hereinbefore described,
double male and female screw clutches with either the male or female portions made
elastic, may be substituted.
For the purpose of uncoupling Railway vehicles provided with the aforesaid
clutches, this may be effected by hand by lifting the counterweights or loosening
the screws or wedges thus leaving the pins or catches free to be withdrawn from
the clutches or the uncoupling may be effected at any part of the train either by
mechanical or electrical connections which will raise the levers which carry and
retain the pins or catches. These electrical or mechanical connections are or may
be operated either from the engine or guards van and a dial plate or indicator is
attached provided with a pointer to shew the part at which the uncoupling is
effected.

" IMPROVE-
This invention is designed to economize labour in the preparation of plates for
cylindrical printing machines
It consists First in taking the damp paper moulds and instead of drying them in
sand or under a press bending them round in a cylindrical case preferably of the
exact size of the cylinder of the printing machine. This case has hollow walls
filled with steam from a boiler. A gentle current of air can be allowed to
circulate and carry off the vapour arising from the mould. As no pressure of sand
is applied to the dead spaces they are not pressed in unduly but remain nearly as
when in the damp state.
Second, in forming a series of gauges which fit into the casting blocks round the
heading and close up to the rule or type on every side. That on the side where
the metal is poured in is very thin so as to allow for gates and instead of a gate
the entire length of the side blocks are inserted in the casting blocks lessening the
width of the gates so that the thin gauge shall be supported and not have to span
such a large space and so be less likely to bend or sag
These gauges are so accurately fitted that they cover with a thin projection the
strips on the mould immediately round the type and thus dressing and finishing is
avoided.
This invention is also applicable for printing with flat plates in such case the
drying chest is rectangular instead of cylindrical & I place the table on top of the
drying chest.

An ordinary exhaust fan as now in use is fitted at the outlet pipe thereof with
one or more concentric pipes or rings-to each of which pipes or rings is attached
and fixed a pipe called by me the intake pipe
The apparatus is actuated by the motion of the fan which after having drawn
or exhausted air thro' the ordinary intake pipe discharges the same thro' the
ordinary outlet pipe into the surrounding or concenteric pipes or rings-The air or
vapor thus discharged in its passage thro' such surrounding or concenteric pipes
or rings and by virtue of its expansive properties creates rapidly an imperfect or
partial vacuum-This vacuum is supplied or filled as rapidly as exhausted with
air or substance to be removed thro' the intake pipe attached to each concentric
ring and this action sets up a rapid current of air in each intake pipe and each
concentric ring thus causing in each intake pipe a very powerful means of exhaust
and in each ring as powerful a discharge and tripling or quadrupling the ordinary
power of the fan.
In the accompanying plan which is a section of the apparatus "AAA" is an
ordinary fan enclosed in an ordinary case with the usual intake and outlet pipes.
"B. B." are the "concentric rings" surrounding the ordinary outlet pipe and each
other and "C. C," the intake pipe attached to each ring.
The mode of application is for the three or more or less intake pipes (as the case
may require) to be put into the space from which it is required to exhaust. The
fan is then set in motion and the exhausted or wasted air from the ordinary outlet
pipe becomes the force which passing thro' the surrounding pipes creates the
imperfect vacuum before named and sets up the current of air which affects and
ל

page_text: actuates the inlet pipes-The waste air thus becomes in this apparatus the means
or motive power of exhaust and is found on experiment that the exhaust action is
far greater in the pipes "C. C," than in the ordinary fan exhaust.
The apparatus is driven by any convenient motive power and is capable of
exhausting steam water dust or anything of like nature

aforesaid inner one, is open at both ends and has a flange round the top thereof.
Upon sliding the outer tube up the exterior of the inner tube, the interior of the
aforesaid inner one is exposed by means of the aforesaid opening and this inner

RICHARD HODSON of the Thames Iron Works, Black wall in the County of
Middlesex, Civil Engineer "IMPROVEMENTS IN "ROTARY, ENGINES."
This invention relates more particularly to improvements in the rotary engines
for which I have obtained Letters Patent dated respectively the 22nd day of
December 1875 No 4458, the 24th day of August 1877 No 3224, and the 9th day
of September 1881 No 3920, the object being to provide a packing whereby the
leakage of steam through the bearings of the main shaft, or of the oscillating valve
spindle will be avoided, while at the same time efficient and economical lubrication
of the bearings will be ensured, the heating of the bearings prevented, and friction
considerably reduced.
In carrying out my invention I truly face the cylinder cover, and I form a
recess in the end of the piston. In this recess I insert. a ring the outer edge of
which is also faced to correspond with the cylinder cover. The inner periphery of
this ring
cut away to form a chamber into which, when the shaft is in place,
asbestos or other suitable packing is placed. The packing is held in the chamber
in this ring which may be termed a gland box, by a second ring which may be
termed a gland, the gland being pressed in by a spring which has for its abutment
a collar or washer which fits against a shoulder pin or key on the shaft, but the
abutment may in some instances be taken from the piston itself. I may also use a
steam spring.
The bottom of the gland box is inclined, and as the gland presses on the packing
it will be forced tightly onto the shaft by the inclined portion of the box and form
a perfectly steam-tight packing round the shaft. At the same time the spring will
act on the gland box and press it against the cylinder cover, and thus make a
steam tight joint at that point.
The lubricating oil is allowed to run between the gland box and the cylinder
cover from a cup suitably placed for the purpose, and it finds its way into the
bearings thus lubricating them.
For ordinary purposes it is only necessary to have one of these packings at
opposite ends of the cylinder, but if desired one may be placed on either side of the
diaphragm in addition.

page_text: The packing for the oscillating valve shaft will be of the same construction, but
the spring may be dispensed with, the pressure of the steam in the steam chest
acting upon the valve rod spindle being sufficient to keep the gland ring well in
position.
Although I have described this packing as applied to my rotary engines I would
remark that it is equally applicable to other rotary engines whether worked by
steam, gas, air or water.
If desired the gland box may be made with a flange of greater or less width so
that it may take the whole or the greater portion of the rubbing surface of the ends
of the piston.
The gland box and gland are so connected with the shaft that they may rotate
with it, but be capable of sliding longitudinally on it. In the same way the piston
may be allowed to slide upon the shaft.

CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane
in the County of Middlesex "IMPROVEMENTS IN PORTABLE BAKING OVENS
[Communicated to him from abroad by Girolamo Taddei of Turin in the Kingdom
of Italy Engineer]
According to the present invention portable baking ovens, intended more parti-
cularly for military purposes, are constructed as follows:
The oven consists of two chambers with rectangular sides and arched tops the
one being situated within the other, with a narrow space intervening between tho
two. The bottom part of the outer chamber or casing extends downwards some
distance below the bottom of the inner chamber with inwardly curved sides,
terminating at bottom in a firegrate below which is an ashpit, the lower part
of the outer casing being thus made to form the fire box of the oven the flames
from which play all round the sides of the inner baking chamber and, escaping
through openings provided with slides at each end of the top space between the
two casings, pass along to the middle of the same where a chimney flue is provided.
This flue is made to turn down on a hinge for transport and the flue opening in
the casing is then closed by a cover.
The bottom surface of the inner chamber is protected against the direct fire heat
firstly by a double bottom filled with a bad conductor of heat, and secondly by a
curved shield projecting downwards towards the firegrate at the middle so as to
direct the flames towards each side of the chamber. The outer casing is also
provided with double sides and top, filled with a bad conductor of heat to prevent
loss of heat by radiation. The inner and outer casings are tied together by strong
tie bolts. On each sido of the firebox are arranged external cylindrical vessels
filled with water, in which steam is generated for supplying the interior of the
baking chamber with the necessary steam for carrying on the baking process, such
supply being effected through a regulating valve or cock; small openings are also
provided having doors or slides for admitting air into the chamber for cooling and
drying purposes. The baking chamber is divided by removeable trays or partitions
with double bottoms into an upper and lower compartment, and access is gained to
each of these by a separate door at the front end of the outer casing also made with
double sides filled with a bad conductor of heat.
The oven is mounted upon either one pair or two pairs of wheels and is provided
with shafts to be drawn by horses.

Secondly. To the construction and use of a shuttle guide and spring or springs
so arranged and combined as to act as shuttle guide and swell.
Thirdly. To an improved temple roller adjustable to varying widths of cloth
being woven.
Fourthly. To improved apparatus for taking up the cloth as woven without
the aid or use of the cloth beam or roller as ordinarily used.
Taking-up levers constructed according to this my said invention consist of
three parts, the lever having a clip or forked end within which the catch is received,
there being then introduced a dove tailed or angled locking piece in position.
Another construction comprises three pieces or parts the lever having a detachable
side piece extending from catch end of the lever to and including half or part of
the eyes for fulcrum stud and catch, the said side piece being bolted to the main
part of lever admits of removal and replacement of the catch when necessary.
Another construction comprises a clip at the end of the lever the catch having an
oblong projecting pin so that when the narrow side of the said pin is passed through
the slit leading to the clip on the oblong pin reaching the clip and being turned a
quarter revolution or into its working position it is securely held by the clip and
pin.
The shuttle guide I construct so as to be adjustable and movable and employ in
connection therewith a blade or spiral spring mounted upon guide studs so as to
ease and secure the shuttle on its entry into the box.
Temple rollers I construct of slightly taper or conical outer metallic roughed
cylinders mounted upon and secured to an inner shaft, and having end studs or
axles on which the whole rotates, the metallic covering is adjustable so that the
length of roller may be varied at will.
In lieu of the ordinary cloth beam or roller I attach to the axis or shaft of the

These Improvements relate to the Telephone Transmitters in which Carbon
Electrodes are employed in combination with powdered carbon for which Letters
Patent were granted to Alexander Marr dated the twenty first of June One thousand
eight hundred and seventy nine No. 2497.
In carrying out my Invention I mount upon the back of the diaphragm or
tympan one or more cells or shallow boxes to contain the Electrodes and the
powdered carbon-The carbon Electrodes may be attached to the back of the
diaphragm with an insulated space between them or one only of each pair may be
on the diaphragm the other being on the opposite side of its box-In either case
the circuit between the Electrodes is completed by the powdered carbon which acts
in conjunction with the Electrodes as a tension regulator. The diaphragm may be
of wood or other suitable material but I prefer to make it of sheet ebonite-Instead
of carbon any other substance possessing similar qualities may be used.
By means of this Invention the Electrodes and the carbon powder or tension
regulator is caused to vibrate with the diaphragm under the action of sound
producing a greater loudness and purity of tone in the receiver.

METAL PLATES OR SHEETS, APPLICABLE ALSO FOR ANNEALING OR CALCINING OTHER
MATERIALS
"
Our Invention consists in an improved arrangement of the furnace fittings and
apparatus connected therewith for annealing metal plates more especially with
reference to plates in the tin plate manufacture, although applicable to annealing
other metal articles, glass pottery or the like.
Our Invention has for its object the more equal diffusion of heat over the
annealing pots or vessels so that they may become more evenly and at the same
time rapidly heated throughout thus securing more effective annealing and also
preventing the pots or vessels from being damaged by unequal heating.
To obtain this end we enclose the ashpit with a door or doors and dispense with
the natural draft but use an artificial draft instead. For promoting the draft we
employ a fan, steam jet or any other convenient blower, and to make the furnace
self sustaining as to draft, we advantageously place a boiler in any convenient
position between the furnace and the smoke stack, so that the heat after doing its
work in the annealing furnace or oven may raise steam to work the blowing
apparatus.
It is obvious that the artificial draft may be supplied independently. In the
smoke stack there is placed a damper by the regulating of which together with the
draft the desired effect of a general and nearly equal temperature throughout can
be secured. It will be apparent that our furnaces can be used for calcining ores
and other matters the details being modified accordingly.

"IMPROVEMENTS IN GAS MOTOR ENGINES"
My invention relates to a construction and mode of working of a gas motor
engine in such a manner as to avoid the explosive shock resulting from too rapid
combustion of the charge by retarding the combustion within the cylinder.
For this purpose I provide in the cylinder a loosely fitting piston, which is
porous or perforated, consisting of layers of wire gauze or of a number of small
tubes or concentric rings or otherwise constructed with passages such that flame
cannot pass through them. At the time when the cylinder is charged, ready for
ignition, this piston is in such a position that only a small portion of the com-
bustible charge is on one side of it, next the point of ignition, whilst the greater
portion of the charge is on the other side of the piston. When the charge is
ignited on one side of the piston, the fluid on the other side of it is caused by the
movement of the piston to pass through its pores or perforations to the side where
the ignition exists, and thus the combustion of the whole charge is rendered
gradual.

Iron Merchant. "IMPROVEMENTS IN LIFTS OR HOISTS FOR WAREHOUSES AND
OTHER BUILDINGS
"
This Invention has for its object the application in connection with lifts or hoists
for warehouses and other buildings of improved automatic appliances by means of
which gates or doors in the doorways or openings giving access to the cage are
closed on the cage passing from them and opened as the cage is approaching
them.
.
In applying the improved apparatus to the ground-floor or lowest stage of a lift
where there is sufficient head room a vertically sliding gate is employed and chains
from it pass up over pulleys and down to slides moving in guides. These slides are
formed with projections and corresponding projections are fixed to the cage in such
positions that when the cage descends it acts on the slides and depressing them
causes them to raise the gate. When the cage ascends the gate descends by its
own weight at the same rate as that of the ascent of the cage.
At a top flat or stage, or where there is not sufficient head room for a vertically
sliding gate a vertically hinged door or pair of doors is provided there being
connected to each door a cord passing over a pulley to a weight which, tends to
close the door. Another cord passing over a pulley or pulleys is arranged for
opening the door and is either connected to a weight or to a slide arranged to be
acted on by the cage. The cage is provided with a suitable projection which either
lifts one of the weights or acts on the slide so as to open the door when approaching
it, the door closing by the action of the weight provided for that purpose when the
cage passes away from it.
Where there are several flats or stages served by the same lift or hoist selfacting
gates or doors may be fitted at each stage; the acting pieces on the cage being
arranged to act on each gate or door in succession and pass it. Or adjustable parts
may be applied to restrict the opening action to such stage or stages as may be
desired.

COVERINGS
a communication from abroad by Etienne Manginot, of Toul, France
This invention has for its object the rapid internal ironing of caps and similar
head gear, so as to dispense with the external application of the iron.
The apparatus consists essentially of four pieces, of which the upper ones are of
iron and fit into the cap, while the lower ones are made of wood and serve to
support the iron part by means of tenons or pins-The lower parts are hinged
together at the centre of their base and provided near their top with a screw
spindle having a handle by the turning of which the two lower parts can be
brought nearer to or further away from each other, each part carrying with it one
of the two parts attached to its top, thereby increasing or decreasing the distance
between the two upper parts, in order to fit various sizes of caps.

JOHN CLAYTON MEWBURN of 169 Fleet Street in the City of London, Patent
Agent and Consulting Engineer "IMPROVEMENTS IN PROTECTING WIRES OR
CABLES FOR CONDUCTING ELECTRICITY" A communication from abroad by
Antoine Marie Jarriant Jeune of Paris France
The wires and cables now employed in the various applications of electricity
are covered, externally to their insulating coating, with a protective jacket which
is generally of cotton in the case of wires and of lead in the case of cables-The
cotton covering does not perfectly protect the wire while the lead covering much
increases the weight of the cable besides adding considerably to the expense. Now
the present Invention consists in surrounding electric conducting wires and cables,
after they have been insulated with ordinary insulating materials, or with
Chatterton" bands or strips, with a braided plaited or woven metallic covering,
According to the particular use for which the electric conducting wire or cable is
intended, the braided, plaited or woven covering may consist of iron wire
galvanized or not, or copper or brass or other wire, and in cases where the electric
conductor is to be employed in houses the covering wires may be nickeled, silvered
gilt or otherwise ornamented.
The metallic braided covering may be conveniently applied by means of a
braiding machine such as that employed in making cotton braids.
Electric conducting wires and cables with a protective covering of braided
galvanized iron wire are lighter than cables having a sheathing of lead, they are
very strong and less expensive.
They may be employed in the various applications of electricity such for
example as lighting, the transmission of energy or power by electricity, telegraphy,
telephony electric signals, submarine cables &c.

DANIEL COLEMAN DEFRIES, of the Firm of J. Defries and Sons of No. 147
Houndsditch, London in the County of Middlesex Merchant. "IMPROVEMENTS IN
PENDANT LAMPS, LANTERNS OR CHANDELIERS."
My Invention relates to improvements applied to the basket or other shaped
pendant or hanging lamps, lanterns or chandeliers formed of rows of crystal drops
surrounding a central light, and it consists particularly in the use of a glass or other
transparent inverted cone fitted within such circle of drops, whereby I protect the
flame from vacillating or being extinguished by lateral currents of air, this cone or
conical glass being used in conjunction with a cup so arranged beneath it as to
deflect any upward draught; the use of the conical glass also affording an easy
means of directing any desired colour or variety of colours upon the surrounding
drops whereby very brilliant illuminating effects may be obtained.
While I protect the flame from lateral currents of air by the inverted truncated
cone and from direct upward current by the cup I leave a space between the cup
and the cone by which a sufficiency of air is supplied for combustion.
Should this Lamp be used beneath a Punkah it will be found that although the
downward draught may cause a wavering of the flame the arrangements of the
conical glass and cup will prevent the light being extinguished.
The conical shade may be of one piece of any desired colour or of a series of
pieces of glass or transparent material of various colours and the cup may be of glass
or metal or any suitable material.
Hydro Carbon or other oil Lamps, Candles or gas may be used with my
improvements, and I may use two or more of my improved lamps or lanterns in
combination to form Chandeliers or Pendants of various designs.
My improved Lamp will be found very suitable for lighting and decorating
Verandahs, Corridors, Gardens and all places where the light would otherwise be
exposed to strong currents of air.

WILLIAM MCDONNELL of the city of the County of Limerick Ireland "A
NEW OR IMPROVED MODE OF AND APPLIANCES FOR THE MANUFACTURE AND
PRESERVATION OF A NEW ARTICLE OR FOOD FROM FISH AND OTHER EDIBLE
SUBSTANCES,"
'
The object of this invention is the production of a new article or articles of
food made of fish meat or other edible substances
According to my invention I take fish when that is to be treated and after it is
properly cleaned I place same either in boiling water or hot oil, I then remove the
bones and mince it in any convenient manner and spice and season according to
taste the fish thus prepared is made up into what may be called fish "brawn" or
fish sausage, I then freely boil it and press same into forms of any desired shape
as fancy or taste may dictate.
I employ metallic materials or compositions thereof for wrapping and securing
these new articles of food so as to exclude the action of the air on the contents
and the same may be hermetically sealed. Suitable metals to make cases for
holding the preparations of fish made up as aforesaid are cased lead, hard pure tin,
quite pure tin, hard tin metals cased metal and malleable bronze but any
malleable metal may be used or tin foil or other flexible metal for example such as
that now used for the capsuling of bottles. The receptacles or coverings are in
some cases soldered up air tight.
The malleable material aforesaid is made up according to my invention into
cases of any desired size and shape and for this purpose I employ dies or blocks
or patterns to give or produce the required size and shape; for example these
blocks may be rectangular or round and when the contents are inserted the ends
are folded over and soldered to exclude the air. The blocks or dies enable me
with great facility to form the cases or wrappers for holding the preparations while
at the same time I obtain where necessary a hermetically sealed case.

To cover buildings with slate, tile, stone or other materials. The particulars of
this invention are as follows. First. The slates instead of being double and in some
places treble are only laid single with a sufficient lap. They are laid in the form of
diamonds or fish scales. This invention will save material and labour and be a
lighter roof.
The slates are cut square but will do otherwise the first layer next the front of
the building will be laid in the usual way, then they are laid in diamond form. It
is necessary in doing so that half slates must be used next a gable and in the roof
tiles and stone can also be used under this patent, the former being made flat and
moulded square and if the edges of the tiles have a turned up ledge they will turn
the weather without pointing.

"IMPROVEMENTS IN THE CONSTRUCTION OF PICKER-ARMS FOR POWER LOOMS."
This Invention which relates to Improvements in the construction of picker-
arms for power looms has for its object to render that end of the arm through
which the picking bolt or thong passes, more durable than at present, and the
Invention consists in fixing in that end of picker-arms at the position, which the
hole formed therein usually occupies, a metallic piece having a hole in the centre of
a bolt or thong to pass through, and provided with a flanch round the same, of
about the same width, as the leather of the picker-arm is formed. Holes of the
requisite size are formed at the outer layers of the leather of the picker-arms,
which allow the central projection parts of the metallic piece to pass into, whilst
the said metallic piece, and leather parts are secured together by rivets, bolts,
sewing, or their equivalents. The requisite "set" of this end of the picker-lever is
rendered permanent by rivets passed through the layers of leather.
