Ax IMPROVEMENT IN THE CONSTRUCTION OF COKE OVENS
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by Joseph Dunning at the
Office of the Commissioners of Patents, with his Petition, on the
1st November 1852.
(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, JOSEPH DUNNING, of the Parthenon Chambers, No. 14, Regent
Street, in the Parish of St. James, in the City of Westminster, Sur-
veyor, do hereby declare the nature of the said Invention for "Ax
IMPROVEMENT IN THE CONSTRUCTION OF COKE OVENS " to be as follows, that
is to say-
For the purpose of conveying and applying the heat arising from
the ignited coal in coke ovens, during the process of coking, more
efficaciously to the whole charge of coal to be coked, and especially to
the lower portion and the under surface thereof which is next to and
upon the floor of the oven, instead of permitting the heat to pass away
at the top or back of the oven (according to the method hitherto prac-
tised) through a flue leading directly into a chimney; I construct in
the sides of the oven vertical flues, having their upper orifices in the
interior of the oven a little above the springing of the arch of the
roof, and made to open at their lower ends into and to communicate

page_text: with a series of horizontal flues, constructed under the floor of the oven.
This series of horizontal flues I make to open into and to communicate
with chimnies, built in the substance of the sides of the oven. [ also
construct in the sides of the oven horizontal flues parallel with the
direction of the said sides respectively, and opening at one end of each
respectively into the above-mentioned vertical flues respectively, and at
their other ends into the above-mentioned series of horizontal flues under
the floor of the oven; and in order better to regulate the heat which
will be carried down the vertical flues to the horizontal flues during the
process of coking, by permitting the escape of a portion of the heat
(should it at any time become excessive) before it passes through the
horizontal flues under the floor, I make these last-mentioned horizontal
flues to open into the external air by two or more openings (according
to the size of the oven) made through the walls of the oven. These
openings I close with doors of the usual and proper kind for the
purpose of confining the heat within the flues, or allowing it to escape
when necessary.
IM- PROVEMENTS IN THE GENERATION OF ELECTRICITY
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by Louis Napoleon Legras and
William Lawrence Gilpin at the Office of the Commissioners of
Patents, with their Petition, on the 23rd October 1852.
We, LOUIS NAPOLEON LEGRAS, of Wenlock Street, Hoxton, in the
County of Middlesex, Gentleman, Civil Engineer, and WILLIAM
LAWRENCE GILPIN, of Bayswater, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS IN THE GENERATION OF ELECTRICITY" to be as follows, viz. :—
This Invention consists in or has reference to improvements in the
generation of electricity.
These improvements are effected by using a battery, partly magnetic
and partly voltaic; that is, consisting of a cylinder or other suitable
piece of iron, or compounds of iron or metal, used with a solution com-
posed of any common salts and water or other suitable liquid.
By generating electricity by the above means many advantages will
be obtained.
IMPROVEMENTS IN CHESS AND DRAUGHT BOARDS
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by John Jaques the younger
at the Office of the Commissioners of Patents, with his Petition,
on the 1st November 1852.
I, JOHN JAQUES the younger, of Hatton Garden, in the County
of Middlesex, Ivory Turner, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN CHESS AND DRAUGHT BOARDS" to be as
follows:-
I construct the board with flaps and hinges to enable it to form a
flat board for playing, and when not in use to be folded up in the form
of a box or tray. The chess or draught men have pegs which take into
holes in the centre of the squares of the board, and in the event of the
game being interrupted, by simply turning up the flaps at the side of the
board a spring or springs comes or come into action, and the men are
retained in their position, and so firmly, that the board may, if desired,
be folded up into the shape of a box without the men falling or leaving
their position..

AN IMPROVED CHAIN CABLE
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by George Rennie at the
Office of the Commissioners of Patents, with his Petition, on
the 1st October 1852.
I, GEORGE RENNIE, of Holland Street, Blackfriars, in the County of
Surrey, Esquire, do hereby declare the nature of the said Invention for
"AN IMPROVED CHAIN CABLE" to be as follows:-
My improvement consists in forming the links of chain cables in
such a manner that they shall bear the greatest possible strain with the
least quantity of metal; or, in other words, disposing the metal of each
link in such a manner as that the centre of each link shall be in a direct
line with the line of tension. >
This I accomplish by bending each link of the chain in the form of
so that when the extreme tension or pull takes place
the figure of
in a chain thus formed the form of the links shall be as little changed
as may be from the form given to the links according to my plan.
IMPROVE- MENTS IN SEPARATING GOLD FROM QUARTZ OR MATTERS CONTAINING THAT METAL
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by John Barker at the Office
of the Commissioners of Patents, with his Petition, on the
23rd November 1852.
I, JOHN BARKER, of Richmond, in the County of Surrey, Physician,
do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN SEPARATING GOLD FROM QUARTZ OR MATTERS CONTAINING THAT
METAL" to be as follows:-
According to this Invention, the quartz or material being well
crushed, it is placed with quicksilver, with or without common salt
or other matters, in a barrel or revolving vessel having internal
projections, by which the gold is brought well in contact with the
quicksilver. From this vessel the matters are run into a hopper,
which is kept constantly jogged, and from the lower part thereof
the materials fall on to a trough, which is also kept constantly
jogged. In the bottom of such trough there are holes at intervals,
having guards or shields over them open at the end to receive the
heavier of the flowing materials, but so shallow as to let the less
heavy matters flow over and pass under the next shield or guard,
and so on. Under each of the holes there is a receiving vessel, to
receive the matters as they fall through, and the remainder of the

page_text: matters, if desirable, is then subjected to a washing process in a
vessel having outlets at greater and greater heights. Into the
lower part of this vessel a stream or streams of air are admitted;
whilst water continually flows into the vessel, and as constantly
runs out at the several outlets. By this arrangement the matters
will be kept in constant agitation, and the lighter matters will flow
off with the water, the heavier ones containing gold coming to the
bottom of the vessel. Or the whole of the matters may be thus
treated immediately after amalgamation. The gold is separated
from the quicksilver by causing the matters to be placed in a basin
of wood or other suitable porous matter, under which a partial ex-
haustion is obtained by an air pump or other means, when the
pressure of the air will cause, for the most part, the quicksilver to be
filtered away from the gold, and the remainder of the quicksilver is
drawn off by heat.

THE REVOLVER, A PERFECT SELF-RIGHTING WHALE-FISHING, PILOT, OR OTHER BOAT, TO BE CALLED 'BATES'S LIFE BOAT, (No. 1, OF A SERIES OF NAVAL ARCHITECTURE
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by Edwin Bates at the Office
of the Commissioners of Patents, with his Petition, on the
22nd November 1852.
(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, EDWIN BATES, Geometer, of No. 7, Great Portland Street, Port-
land Place, Middlesex, do hereby declare the nature of the said Inven-
tion for "THE REVOLVER, A PERFECT SELF-RIGHTING WHALE-FISHING, PILOT,
OR OTHER BOAT, TO BE CALLED 'BATES'S LIFE BOAT,' (No., 1, OF A SERIES OF
NAVAL ARCHITECTURE)," to be as follows:-
By a greater knowledge of geometry probably than ever one man
before possessed, I define positively the outlines of the best life bout.
1st plan. I draw a line to represent a diameter and a semicircle
with radius of half of it, within which, and with of the former
radius, I describe another, and upon it I mark the points of the
sexagon, and from those two points I draw (with the same radius),
lines to join the two semicircles. The four lines described form a
section of the boat as it would appear if cut across.
2nd plan. I describe a circle, and draw a vertical diameter and
equilateral triangle: in the third quarter from the lower end of this
diameter I place the compasses and describe a semicircle with

page_text: radius of half one side of the triangle. The of the circumference
of the large circle and half that of the inner one form the two
bottoms of the boat. Again, I draw a circle, and with the same
radius I fix the compasses on the circumference, and describe
another circle, and what may be termed the moon in this figure
forms the two bottoms.
3rd plan. I draw a line of the proposed width of the boat: I
extend a perpendicular downward to the extent of one fourth of it,
and I describe an arc to pass through this point and each end of
the line, from the quarters of which I describe quadrants; these three
lines form the exterior, and the interior bottom is a semicircle of
the same radius joining the two quadrants and the centre of the first
line.
4th plan. When merely a small and light boat, I construct it in
the form of an egg, but of the same lines as already described.
The balance for such a boat is a ball suspended in the water by a
chain from the centre of the bottom to act with a short keel.
In other cases, the righting power is effected by means of a tube
or cradle, placed between the two bottoms, with a ball or balls,
roller or rollers, or quicksilver, to oscillate from the extremities of
the side of the equilateral triangle, which may be extended to the
extremities of the horizontal diameter of the large circle when the
boat is the entire cylinder. These weights have a transverse action,
and always assist the ordinary keel, but are of the greatest impor-
tance when the boat is keel up, giving the balance in the direction
where it is required.
A NEW OR IMPROVED LOCK
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by Amédée François Rémond
at the Office of the Commissioners of Patents, with his Petition,
on the 26th November 1852.-A communication.
(Void by reason of notice to proceed not having been given within
the time prescribed by the Act.)
I, AMÉDÉE FRANÇOIS RÉMOND, Gentleman, of Birmingham, in the
County of Warwick, do hereby declare the nature of the said Inven-
tion for "A NEW OR IMPROVED LOCK" to be as follows:-
My Invention consists of a lock in which two sets of tumblers a, b,
are arranged, as shewn in the drawing; namely, one above, and the
other below, the keyhole. The tumblers turn upon axes a¹, b¹; c, d, e,
are three projections upon the bolt f. In order to shoot the bolt, it
is necessary to raise the tumblers a, and depress the tumblers b, to
such distances respectively, that the projection d, shall be disengaged
from the recesses a¹¹, 61, when the said bolt f, may be shot; but
the tumblers again returning by the action of the springs on their
ends, the projection d, becomes engaged in the recesses a¹¹1, 6111, and
the tumblers must be again operated upon, in order to disengage the
said projection d, from the said recesses a¹11, 6111, and allow the bolt
to be shot a second time. For this purpose a second key must be
used, as the tumblers require displacing differently in the second

page_text: shooting of the bolt. The projections c, and e, render it necessary
that the tumblers be not displaced beyond the exact distance neces-
sary to allow the projection d, to pass, otherwise the said projections
c, and e, will engage with the tumblers, and prevent the shooting of
the bolt. The number of the tumblers may vary, and the principle
may be extended to three, four, or more keys, and a corresponding
number of shootings of the bolt, or may be restricted to one key and
one shooting of the bolt. 7, is a screen by which a view of the re-
cesses in the tumblers is prevented from the keyhole.
IMPROVEMENTS IN PURIFYING GAS, AND IN OBTAINING FROM THE PRODUCTS RESULTING FROM THE PURIFICATION OF GAS CERTAIN USEFUL COMPOUNDS
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by Richard Laming at the
Office of the Commissioners of Patents, with his Petition,
on the 6th December 1852.
1, RICHARD LAMING, of Millwall, Poplar, in the County of Middle-
sex, Chemist, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PURIFYING GAS, AND IN OBTAINING FROM THE
PRODUCTS RESULTING FROM THE PURIFICATION OF GAS CERTAIN USEFUL
COMPOUNDS," to be as follows:-
One part of this Invention consists in purifying gas by means of a
solution of bone, phosphate, apatite, or coprolite in muriatic or
nitric acid mixed with sulphate or muriate of magnesia, either in a
fluid state, or absorbed into saw dust, or any other convenient
absorbent matter; the object being to purify the gas from certain
of its impurities, and by their means to obtain ammoniaco-phosphate
of magnesia, muriate or nitrate of ammonia, and phosphate, car-
bonate, and sulphate of lime.
Another part consists in purifying gas by means of magnesian
limestone, burned into a caustic state and slaked, and in afterwards
converting the residual sulphuret of magnesium into sulphate of
magnesia by roasting or other node of oxidation. I extract the

page_text: resulting sulphate of magnesia for use in the former part of this
Invention, or otherwise.
Another part consists in purifying gas by means of the aforesaid
magnesian compound, or lime mixed with sulphate of soda or
sulphate of potash.
Another part consists in purifying gas by means of oxides and
salts of antimony, for which purpose they may be used either in dry
or wet purifiers.
IMPROVEMENTS IN BACK FASTENINGS FOR VENETIAN AND OTHER SWING SHUTTERS OR BLINDS, AND ALSO FOR SWING WINDOWS AND DOORS
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by John Neale at the Office
of the Commissioners of Patents, with his Petition, on the 3rd
December 1852.
(Voil by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, JOHN NEALE, of High Street, Ordnance Place, Chatham, in the
County of Kent, Lath Render, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN BACK FASTENINGS FOR VENETIAN
AND OTHER SWING SHUTTERS OR BLINDS, AND ALSO FOR SWING WINDOWS AND
DOORS," to be as follows:-
The object of this Invention is to provide a self-acting back
fastening for shutters, swing windows and doors; its use being in
all cases to withdraw the fastening with ease, but, in the case of
shutters and windows, to enable a servant, when they are required to
be closed, to withdraw the fastening without the necessity of reach-
ing far outwards or going out of doors to unattach the fastening.
For this purpose, and also for holding back folding or other doors,
I employ latches or bolts, whether constructed to act by gravity or
by the elastic pressure of a spring, and I connect therewith a slide,
having a projecting knob for withdrawing the bolt, or a thumb
piece for lifting the latch; placing the knob or thumb piece, when

page_text: applied to windows and shutters, in such convenient part thereof
that it may be readily reached by the servant. The latches or bolts
are made to catch against a staple or hasp driven into the wall of
the building to which the Invention is applied; or they are other-
wise conveniently attached to retain the latches or bolts, and hold
the windows or shutters back as required, and an analogous arrange-
ment is adopted for doors.
In order to secure the shutters, windows or doors, in their back
or open position, it is only necessary to throw them back with
sufficient force to pass their latches or spring bolts over the
retaining catches before mentioned.
IMPROVEMENTS IN TREATING ZINC ORES
Year: 1852

page_text: LETTERS PATENT to Richard Taylor, junior, of Queen Street,
Cheapside, in the City of London, and John Arthur Phillips,
of Upper Stamford Street, Blackfriars, in the County of Surrey,
for the Invention of "IMPROVEMENTS IN TREATING ZINC ORES."
Sealed the 9th February 1853, and dated the 15th December 1852.
PROVISIONAL SPECIFICATION left by the said Richard Taylor
and John Arthur Phillips at the Office of the Commissioners
of Patents, with their Petition, on the 15th December 1852.
We, RICHARD TAYLOR, junior, of Queen Street, Cheapside, in the
City of London, and JOHN ARTHUR PHILLITS, of Upper Stamford
Street, Blackfriars, in the County of Surrey, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN TREATING ZINC
ORES" to be as follows:-
This Invention consists of dissolving the sulphur ores of zinc by
muriatic acid, by which sulphuretted hydrogen will be given off,
which is to be converted into sulphuric acid; or the ores may be

page_text: first calcined, and sulphurous acid similarly used, and the calcined
ore dissolved by muriatic acid. In both cases the zinc is thrown
down from the solution by lime, and oxide of zinc is obtained.
IMPROVEMENTS IN GIVING A METALLIC COATING TO IRON SHIPS BOTTOMS AND OTHER SURFACES
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by John Lyons McLeod at the
Office of the Commissioners of Patents, with his Petition, on
the 18th October 1852.
(Void by reason of notice to proceed not having been given within
the time prescribed by the Act)
I, JOHN LYONS MCLEOD, of Mary-le-bone, in the County of Middle-
sex, Lieutenant in the Royal Navy, do hereby declare the nature of
the said Invention ful "IMPROVEMENTS IN GIVING A METALLIC COATING TO
IRON SHIPS BOTTOMS AND OTHER SURFACES" to be as follows:-
My Invention consists in a method of covering metals, wood, or other
materials with thin plates, sheets, or leaves of any metal required for
that purpose, by attaching them with marine glue or any varnish,
cement, or similar adhesive matter. When iron or wooden ships'
bottoms are required to be covered, the surface must be made as dry as
possible, and prepared with varnish, in a cold or hot liquid state, laid on
with a brush, and the sheets of metallic foil may be treated in the same
way, and then attached to the surface in succession, commencing from
the keel upwards, & from the stern to the stem, thus allowing each
sheet to lap the one over the other; and when the entire surface is so

page_text: covered to a sufficient height above the water line I recommend a
metallic band of the same quality as the foil used to pass round the
vessel, and press against the edges of the uppermost sheets of foil, to
prevent their being rubbed or chafed by boats coming alongside or like
casualties.
I do not confine myself to any particular metal or thickness of metal
to be used as a coating, nor any particular adaptation of such coating,
neither has my method of using such metals any similarity to the known
inethods of gilding or plating; but I claim, generally, the covering of
metals, wood, and other substances with thin sheets, plates, or leaves of
metal, made to adhere as described.
IMPROVEMENTS IN CARRIAGE AND STABLE BRUSHES

Office of the Commissioners of Patents, with his Petition, on the
20th December 1852.
(Void by reason of notice to proceed not having been given within
the time prescribed by the Act.)
I, CHARLES WATSON, of the Bazaar, Harness Department, King
Street, Portman Square, in the County of Middlesex, Saddler, do
hereby declare the nature of the said Invention for "IMPROVEMENTS
IN CARRIAGE AND STABLE BRUSHES" to be as follows (viz.) :-
These Improvements are effected by making brushes of that class
denominated as above as carriage and stable brushes with backs com-
posed entirely of gutta percha or other analogous substance, whereby
pliancy will be given thereto, the backs will not be injured by the
water used therewith, and they will be generally rendered more
useful.
Thus I take a piece of gutta percha and perforate it with holes
suitable to receive the ordinary bristle stops, the lower ends whereof

page_text: I fix therein. I then cover the back with gutta percha solution or
cement, and place thereon a covering piece of gutta percha, which
will thus be firmly secured to the other portion of the back, also of
gutta percha, and form a brush as aforesaid.

of the Commissioners of l'atents, with his Petition, on the
2nd December 1852.
(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, ROBERT KIRKE, of Llanelly Dock, Llanelly, in the County of
Carmarthen, Colliery Agent, do hereby declare the nature of the said
Invention for "AN IMPROVED GRATE OR APPARATUS FOR BURNING FUEL,
ESPECIALLY ADAPTED FOR ANTHRACITE COAL, WHETHER USED UNDER REVERBE-
RATORY FURNACES OR BOILERS, OR WITH OR WITHOUT A BLAST," to be as
follows, viz.
This improved grate or apparatus for burning fuel, especially
adapted for anthracite coal, whether used with or without a blast,
consists of hollow bars through which water or steam is passed
through the fire place, combined with a due supply of oxygen, and
by the combination of the gases the desired result of perfect com.
bustion and economical use of anthracite fuel is assured, with the
great desideratum of perfect safety to the bars" themselves, which

page_text: with common care will last for years; whereas the use of anthracite,
with a blast with the common or usual sort of fire bars, subjects
the bars to be melted down in a few hours, and even without a
blast, anthracite injures them much more than any other fuel does.

facturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN ORNAMENTING ENAMEL WATCH DIALS, AND THE MANNER
IN WHICH THE SAME IS TO BE PERFORMED," to be as follows (that is to
say): -
My Invention consists in embossing or engraving, or producing
the resemblance of embossed or engraven designs on the surfaces
of enamel watch dials. The method I prefer employing is as
follows:-I take an ordinary enamel watch dial and draw upon its
surface any design that may be required. I then take fluoric
acid, consisting of Derbyshire fluor spar and oil of vitriol, and by

page_text: means of a fine camel hair brush apply it to those parts of the
design requiring to be sunk or cut in. After this has remained on
a sufficient time, I cleanse the dial with oil, and afterwards polishi
it in the usual manner.
Having thus described the nature of my said Invention, and the
manner in which the same is to be performed, I wish it to be
clearly understood that I do not confine myself to the precise
details nor to the use of the particular acid above mentioned; but
what I claim as my invention is, the embossing, or engraving, or
producing the resemblance of embossed or engraven designs on
enamel watch dials.
In witness whercof, I, the said John Webb, have hereunto set
my hand and seal, this Thirteenth day of December, in the
year of our Lord One thousand eight hundred and fifty-

Our Invention consists in or has reference to an improved means of
heating, cooking, and warming, which will afford heat for those purposes
by increasing the heating power of a gas or other suitable flame,
properly applied in connexion with the said means, as hereafter set
forth.
This means consists in using in a suitable stove (most of the close
stoves if provided with flues being suitable) an unconsumable compo-
sition consisting of pipe clay or other clay (or clay and dung), hay,

page_text: straw, or suitable vegetable substance and water, or of pipe clay or
other clay, muriatic or other acid and water, whiting and other calca-
reous substance, and alum or compounds of alum, which is compounded
together and then calcined by great heat, when it becomes a spongy
mass, which being placed in a suitable stove or apparatus for heating
or cooking, such as shall allow fire from a gas burner or other suitable
flame supplier to impinge upon and play through the above-named
mass so as to cause it to become hot, it will then afford greatly increased
heat so as to effect the purposes of heating, cooking, or warming, as the
case may be; and pipes may be used to circulate the heat, obtained as
above, throughout a house or building.

J, JOHN WOODS, of Rainhill, in the County of Lancaster, Tool Maker,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN SCREW STOCKS" to be as follows: -
My improvements relate to such screw stocks as are used for
cutting screws by hand, the points of novelty consisting in the method
of mounting and arranging the dies and in forcing the cutting (lie
forward. Within the screw stock are former two recesses, in which
the dies are placed; one of these is elongated, and within the elongated
part is placed a nut capable of being turned upon a screw, also placed
in the recess; one portion of the nut turns in a slot, which prevents
it from moving forward, so that upon turning the same the screw is
compelled to advance and carry forward the die so as to operate upon
the metal to be cut. Upon the top of the stock is placed a plate,
which being kept down by screws retains the dies in their seats. This
plate, however, may be removed by slipping it upon the said screws by
means of slots, in order to remove the dies and replace them by others
suitable for cutting another description of screw.
IMPROVEMENTS IN APPARATUS FOR SEPARATING GOLD FROM AURIFEROUS SAND AND EARTH

page_text: PROVISIONAL SPECIFICATION left by George Stenson at the
Office of the Commissioners of Patents, with his Petition, on the
1st November 1852.
(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, GEORGE STENSON, of the Town and County of Northampton,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR SEPARATING GOLD FROM AURIFEROUS
SAND AND EARTH" to be as follows:-
Figure 1, of the annexed Drawings represents my apparatus in a
state for working. A, is the hopper, into which auriferous sand or
earth is placed; B, B', an inclined plane with an aperture across it
leading into a pipe C; c, is a bridge or stop on the further side of the
aperture. Water is supplied from a pump of the peculiar construction
shewn in Figure 2, through the pipes E, and F. The water flowing
from the pipe E, liquifies the sand or earth, and causes it to flow down
the inclined plane, while the water forced through the pipe F, ascends
into the mass through the pipe C, with sufficient force to carry all
matters lighter than gold over the bridge c, and along the end B', of
the inclined plane, while the particles of gold themselves fall into a

page_text: receiver at the bottom of the pipe C. For the sake of recovering any
minute particles of gold which the current of water may have carried
over and past the stop c, I provide ridges across the inclined plane
between the stop and the end thereof.
The pump is contrived for the purpose of obtaining and maintaining
any particular degree of pressure required. In Figure 2, A, is the
pump barrel with induction and eduction passages and valves, as
usual; B, is a supplementary barrel, with a piston weighted to the
pressure required. On the pump being set to work water is forced into
the barrel B, from which a continuous stream issues at an uniform
pressure. By varying the weight on the piston the pressure will, of
course, be also varied.
I desire to claim the apparatus shewn in Figures 1, and 2, whether
used together or separately, for the purpose of separating gold from
auriferous sand and carth, as before described.
IMPROVED APPARATUS FOR VENTILATING CHIMNIES AND APARTMENTS
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by Robert William Billings
at the Office of the Commissioners of Patents, with his
Petition, on the 17th December 1852.
(Void by reason of notice to proceed not having been given
within the time prescribed by the Act.)
I, ROBERT WILLIAM BILLINGS, of St. Mary's Road, Canonbury, in
the County of Middlesex, Architect, do hereby declare the nature
of the said Invention for "IMPROVED APPARATUS FOR VENTILATING
CHIMNIES AND APARTMENTS" to be as follows:-
The chief object of this Invention is to obtain a better ventilation
for the chimnies of dwelling houses and the flues of ships' stoves.
This I effect by the use of an apparatus which prevents the down-
ward draught caused by high winds, and cuts off the access of damp
or rain to the chimney. The apparatus I propose to make of sheet
zinc, but other materials may be employed. It consists (by prefer-
ence) of a rectangular casing or shaft, which is closed at top, but
is open at bottom and at two opposite sides, and is inserted in the
chimney to a given depth, so as to form-a continuation of that flue.
The depth of the insertion I propose to determine by the position
at which I place two pairs of rigid wings composed of plates, which
project from opposite sides of the rectangular casing, for the

page_text: purpose of acting as wind guards for the flue vents, which are
formed in the sides at the part shielded by the guards. I contract
the space within the casing by the insertion of two diagonal
partitions, rising from the lower edge of the vents, and respectively
secured to, or forming part of, the sides of the casing. These
partitions fall towards each other, and they terminate near the
crown or top of the casing, thereby forming a central flue for the
passage upwards of the smoke and gases of combustion; and two
side flues, down which the smoke and gases pass, to make their exit
at the side vents. When, therefore, a wind is blowing in the
direction of one of the vents, the smoke or gases of combustion will
escape at the opposite side of the casing, and if blowing at right
angles, or any other angle, to the face of the escape sides of the
casing, the rigid guards will divert the action of the wind. I also
propose to apply this apparatus to the roofs of buildings, parti-
cularly warehouses and stores, and also to the decks of ships, for the
purpose of ventilating the same, as I find I am enabled to obtain a
considerable draught with a comparatively short casing or shaft.
IMPROVEMENTS IN MOURNING BANDS FOR THE ARM OR HAT
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by Donald Nicoll at the
Office of the Commissioners of Patents, with his Petition, on the
1st October 1852.
(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, DONALD NICOLL, of the firm of H. J. & D. Nicoll, of Regent Street;.
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN MOURNING BANDS FOR THE ARM OR HAT" to be as follows:-
The Invention consists in improvements in hat bands and in bands for
the arm, to be used chiefly for the purposes of complimentary mourning:
The liat bands generally worn at the present time are made of elastic
or other fine cloth, and varying in width. Crape, which was once the
only material employed for this purpose, is now almost entirely disused,
it being proved to spoil by rain, whereas cloth, properly finished, is
never injured by water. There are no means at present of distinguish-
ing by the hat band between court, general, family, or complimentary
mourning, except it may be that a widower will wear a broader band
than in any other case, but this is arbitrary and uncertain, and there is
certainly no intermediate degree. Now the object of this Invention is
to supply this want, and to enable persons to denote in this article of
apparel a degree of mourning; and we effect this purpose by using

page_text: bands of certain widths, and having thereon distinguishing marks,
forms, and devices. We stamp or emboss, either in relief or sunken
letter or figure, a name, motto, or design, heraldic or otherwise, upon
the band for the hat or arm; and this application of a design to this
purpose constitutes an entirely new feature in hat bands. For instance,
on the occasion of the death of the Duke of Wellington, we propose to
emboss on fine cloth the name Wellington, enclosed by a wreath of
laurel or cypress, forming a very appropriate memorial for public use,
or as an arm band for officers in the army, navy, or militia. Or the
word Waterloo might be introduced, or some motto or sentiment.
The letters and design may be white on a black ground if desirable,
but the former would be more quiet and gentlemanly in appearance;
and we have shewn in the annexed Drawing a hat band made according
to this part of our Invention. There are various ways of denoting by
-devices or designs, as well as by width in the band for hats, the par-
ticular kind of mourning worn; for instance, we have shown in the
Drawing one intended to be worn for family and one for compli-
mentary mourning, but as the character and principle of our Invention
will be clearly understood by what is already shewn and described, it
will be unnecessary to go further into detail. We desire to be understood
not to confine ourselves to the use or employment of any particular
mode of embossing, stamping, or marking any letter, device, or design
on fabrics to be employed as hat or arm bands for mourning, but we
claim the manufacture and use of hat or arm bands having thereon
devices, designs, or letters embossed, stamped, or printed thereon.
IMPROVEMENTS IN MACHINES FOR CLEANING KNIVES
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition,
on the 1st October 1852.
I, RICHARD ARCHIBALD BROOMAN, of the firm of J. C. Robertson &
Company, of Fleet Street, in the City of London, Patent Agents, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINES FOR CLEANING KNIVES" to be as follows:-
The improvements consists in placing the brushes or other cleaning
and polishing surfaces horizontally, instead of vertically as is now
practised in all knife-cleaning machines. Two circular brushes are
mounted horizontally in a frame, and are fixed to an axis, on which
is a bevelled tooth wheel set in motion by another bevelled wheel
mounted on a spindle which extends to the outside of the frame, and is
worked by a crank handle. The handles of the knives lie upon a rest
provided for them all round the machine, while the blades are inserted
between the brushes. Polishing powder is supplied, as required,
through openings provided for the purpose in the frame and in the
back of the top brush, or it may be supplied through an opening near

page_text: the axis, when, from centrifugal force, it will get distributed all over
the brushes. The outer edges of the bristle holders are filled with
bristles for the purpose of cleaning the guards or rests.
The advantages of this machine over one of equal size where the
brushes act vertically consists in its capability to clean from three to
four times more knives in the same time, and also in its cleaning the
guards or rests, which the vertical machines do not accomplish.

CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR ROVING OR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES FOR SPINNING
Year: 1852

page_text: LETTERS PATENT to Martin Watts, of Patricroft, near Manchester,
in the County of Lancaster, Cotton Spinner, for the Invention of
"CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR ROVING
OR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES FOR SPINNING."
Sealed the 5th January 1855, and dated the 30th October 1852.
PROVISIONAL SPECIFICATION left by the said Martin Watts at
the Office of the Commissioners of Patents, with his Petition, on
the 30th October 1852.
I, MARTIN WATTS, of Patricroft, near Manchester, in the County of
Lancaster, Cotton Spinner, do hereby declare the nature of the said
Invention of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS POR
ROVING OR PREPARING COTTON AND OTHER FIBROUS SUBSTANCES FOR SPINNING
to be as follows:-
The said improvements apply particularly to the preparation machine
known as the "roving" or "jack" frame. The nature of the said

page_text: improvements consists in a peculiar construction of roving frame,
whereby the slivers as they are brought from the "drawing frame "
are reduced or "drawn," afterwards "doubled" and reduced or drawn
again, and finally twisted and wound on to the bobbin in the form of a
"roving," the whole operation being completed in one machine. The
improved construction or arrangement of machinery whereby this
object is effected will be readily understood by referring to the accom-
panying Sketch, in which a, a, represents the cans in which the slivers
are brought direct from the ordinary drawing frame; b, b, is the "roller
beam supporting the first set of drawing rollers c, c, and the second
set of drawing rollers d, d; and e, e, is the ordinary roving spindle and
flyer. The slivers are doubled between the first and second sets of
drawing rollers, and the spindles and flyers are all placed in one row,
which allows all the rovings the same length for twisting between the
second set of drawing rollers and the spindles, and thus produce more
uniform rovings than heretofore. The advantages arising from the use
of the said improvements are, first, the saving of the entire cost and
wear and tear of the slubbing machines (by thus being able to dispense
with such machines), and also of all the labor of attending to the
same; secondly, a saving of 20 pr cent. or thereabouts in the labor
required for roving, as the supply of the material for the above de-
scribed double beam roving frame will be required but once a week
instead of once a day as at present; thirdly, only half the quantity of
"piccings" (or joinings) and "single" (or unequally doubled rovings)
will be made, and a much more uniform thread will be produced in
consequence of the drawing being more even, and not stretched in
the operation of slubbing; and fourthly, a saving of about 20 p. cent.
in oil, waste, and power.
IMPROVEMENTS IN LOOMS FOR WEAVING
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by John Frame at the
Office of the Commissioners of Patents, with his Petition, on the
5th November 1852.
(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, JOHN FRAME, of Glasgow, in the County of Lanark, North
Britain, Engineer, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN LOOMS FOR WEAVING" to be as follows:-
This Invention relates to the so arranging a power loom that two
separate pieces may be woven in it, one on each side, without taking
up more space than is involved in the ordinary single loom, whilst the
working details are simplified and reduced in number, and essential
compactness is secured. The two yarn beams are placed side by side
overhead in the centre of the loom, and the warps descend therefrom, side
by side, to suitable guide rollers, and then each passes off horizontally
through its heddles and reed to a cloth heam, one at the back and onc
at the front of the loom. Strictly speaking, the loom has no back, as
there is a cloth beam on each side, and the whole details extending to
the loom's centre are duplicates of each other, resembling a pair of looms
placed back to back with the yarn beams elevated between them. A

page_text: single central crank shaft works both slays by means of a double set of
connecting rods, passing in opposite directions to reach each slay. By
this means the loom's action is accurately balanced, and a high rate of
working may be obtained. The heddles for each side are worked from
a single set of central cams, and instead of the usual reversing tension
pulley, each set is strained in a light frame by an adjusting screw, like
a saw frame, so that any required tension may be given to the heddles
entirely within the reciprocating parts. The connection with the cam
levers below is by a light vertical rod on each side. Each shuttle is
actuated by a single central picking stick, worked by a cam, in any
convenient manner. By such an arrangement the attendant can
produce an increased amount of work, whilst superior facility is afforded
for seeing, regulating, and adjusting the warp and other details.
IMPROVEMENTS IN SHEATHING IRON VESSELS, AND IN COVERING, LINING, OR COATING SHEETS OR OTHER MANUFACTURED ARTICLES OF IRON OR STEEL
Year: 1852

page_text: PROVISIONAL SPECIFICATION left by James Edward Mac Connell
at the Office of the Commissioners of Patents, with his Petition,
on the 2nd October 1852.
(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, JAMES EDWARD MAC CONNELL, of Wolverton, in the County of
Buckingham, Civil Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN SHEATHING IRON VESSELS, AND IN
COVERING, LINING, OR COATING SHEETS OR OTHER MANUFACTURED ARTICLES
OF IRON OR STEEL," to be as follows:-
This Invention relates to the covering, lining, or coating sheets, or
manufactured articles of iron or steel, with a layer of brass or copper,
or an alloy thereof, or of such suitable metals as may be applicable, for
the prevention of the decay, chemical or otherwise, of the iron or body
metal of the surfaces so protected and covered. An example of the
manner of effecting this may be referred to in the case of boilers or
tanks (where the interior surface is to be protected). The connection of

page_text: the plates is by lap joints, and the iron or body metal is simply covered
on one side by a thin sheet of copper or other alloy laid on each of the
surfaces previous to revetting the plates together. As the iron surface is
to be entirely protected on the inner side, the inner lap of the joint has
its copper covering bent over its rounded edge, and turned back on the
outside to the extent of the width of the lap for the joint, so that when
the rivet is inserted it has to pass through five different metal sheets,
two sheets of the coated metal being interposed between the rivetted
surfaces. The head of the rivet is covered by a separate piece of the
coating metal as a species of cap, turned under at the neck, and com-
pletely embracing the entire head.
