IMPROVEMENTS IN STEAM BOILERS AND THEIR APPENDAGES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by John Smith at the Office of the
Commissioners of Patents, with his Petition, on the 8th March
1872.
I, JOHN SMITH, of Crosby Hall Chambers, Bishopsgate Street, in the
City of London, Engineer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN STEAM BOILERS AND THEIR APPENDAGES," to
be as follows (that is to say) :-
This the first part of my Invention, which relates to that description
of tubular boiler in which the circulation of the water through the tubes
for the more rapid generation of steam is effected by double pendant
tubes, the outer tubes being subjected on their external surfaces to the
action of the fire, has for its object the obtaining of a more rapid
circulation of the water by more effectually splitting or dividing the
heated water and steam rising from the outer tubes, and separating it
from the water descending into the inner tubes, and the following is a
simple method of carrying this part of my Invention into effect :-I
continue the inner tube a certain height above the crown plate, and
carry the outer tube to the same height but in a bulb form, so that its
appearance above the crown plate will be that of a sphere with the

page_text: inner tube descending through its central portion. Horizontally round
the largest circumference of this sphere I form a ring of small holes,
and if necessary one or more rows beneath it, and through these holes
the heated water and steam rising from the outer tubes is forced in a
spray or in fine streams into the surrounding water, thereby keeping it
in a constant state of ebullution, and greatly increasing the circulation
of the water and facilitating the generation of steam.
The second part of this Invention has reference to means or apparatus
for preventing the explosion of steam boilers by allowing the steam to
escape immediately it reaches a pressure dangerous to the boiler, and
the following is a simple method of carrying this part of my Invention
into effect:-Into any convenient part of the outer shell of the boiler
where it will be subjected to the full pressure of the steam I screw
or otherwise fix a chamber containing a disc held in its position by
a ring or belt of soft metal or combination of metals, and constructed
so as to blow out at a fixed pressure, there being a cap over it to prevent
its being blown right away and doing any damage. This cap is pro-
vided with an opening to allow the steam to escape, and when desirable
has affixed to it a whistle so that the steam whilst escaping will at the
same time sound an alarum.
IMPROVEMENTS IN LAMPS
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Alexander Browne at the Office
of the Commissioners of Patents, with his Petition, on the 13th
April 1872. A communication from abroad by Thomas Hartley, of
Philadelphia, Pennsylvania, United States of America.
I, ALEXANDER BROWNE, of the Firm of Browne and Company, Patent
Agents, of 85, Gracechurch Street, in the City of London, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN LAMPS,”
a communication from abroad by Thomas Hartley, of Philadelphia,
Pennsylvania, United States of America, to be as follows:-
This Invention consists in constructing lamps in the following manner:
―The wick holder, which should be screwed on to the lamp, I form of a
tube, over this tube I place another tube closed at the top, this outer
tube has one or more holes in it near the top thereof, and on the side
there is a handle for the purpose hereafter stated. A flange is made
below the holes to prevent the heat descending to the body of the lamp,
and also for spreading the flame. To use a lamp constructed as above
unscrew the wick holder and pour in the oil or spirit to be used, then
pass a wick through the holder or tube aforesaid, so that it shall be just

page_text: above the top thereof, this done place the aforesaid outer tube over the
tube, with the wick in it, and by applying a light to the holes in the
outer tube the lamp may be lighted and will burn like gas.
By this Invention the light may be regulated by pushing the outer
tube either up or down according to the light required, and this is 5
effected by means of the aforesaid handle on the side of the tube.
IMPROVEMENTS IN FURNACE FIRE-BARS
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by William Henry Dilnutt at the
Office of the Commissioners of Patents, with his Petition, on the
28th March 1872.
I, WILLIAM HENRY DILNUTT, of Mawbey Road, Old Kent Road,
in the County of Surrey, Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN FURNACE FIRE-BARS," to be as
follows:
This Invention relates to improvements in the construction of fire-
bars which possess the advantage of insuring an equable distribution of
air to the incandescent fuel in the furnace, and also provide a larger
grate surface than is due to the area occupied by the fire-bars.
The fire-bars are formed in pairs, and they are cast with lateral pro-
jections from two to three times larger than the thickness of the web of
the bar, and of a depth about equal to that of the web. These lateral
projections are V shaped on their face and taper towards their ends, and
they taper also from the face downwards. The projections on one side
of the bar will coincide with the spaces between the projections on the
opposite side of the bar. These double wedge-shaped projections will in

page_text: the one bar incline upwards from the upper edge of the web of the bar
to the apex of the wedge, and in the other bar of the pair they will
incline downwards in the same degree. The spaces between the pro-
jections will be such as to provide a narrow zig-zag air space of uniform
width between the bars when the bars are set in the furnace. The bars
will alternately be set at a higher and a lower level, and thus the surface
of the fire-place will be increased beyond what is due to its area limits,
and afford increased facility for the admission of air to the fire.
It will be understood that as the fire-bars present an interlocking
surface they will, if made to rock in bearings effectually break up the
superincumbent fuel and prevent the formation of clinkers.
IMPROVEMENTS APPLICABLE TO LITHOGRAPHY, ZINCO- GRAPHY, ENGRAVING, AND SUCH LIKE PROCESSES OF PRODUCING PRINTS OR IMPRES- SIONS
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Henry Louis Delabene Marsden
at the Office of the Commissioners of Patents, with his Petition,
on the 16th February 1872.
I, HENRY LOUIS DELABENE MARSDEN, of Louth, in the County of
3 Lincoln, Surveyor and Lithographer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS APPLICABLE TO LITHOGRAPHY, ZINCO-
GRAPHY, ENGRAVING, AND SUCH LIKE PROCESSES OF PRODUCING PRINTS OR IMPRES-
SIONS," to be as follows:-
These improvements have reference to a process for producing upon
a stone plate or block used for lithographic or zincographic printing or
other printing of similar nature, or on a plate or block used for any
kind of engraving, or on a coating upon the same, a reversed sketch or
copy of the form or outline of the drawing, writing, tint or colour
intended to be printed, accurate in form or outline, free from greasiness,
which can be washed with water, gum, or spirit of turpentine without
being effaced, and is fit for working upon in the usual manner, by a
draughtsman or engraver, with ink or chalk of a greasy nature, or by
engraving or etching, as he would at present work upon a sketch for_the
same purpose made with red chalk or blacklead.

page_text: I use for the above described purpose transfer paper, or papers, or other
substance coated with starch, gelatine, paste, or other similar coating,
and indian ink or water colour or other substance mixed with water or
other fluid, so that the mixture is not of a greasy nature, in the following
or similar manner, namely:-The sketch or copy of the drawing, writing,
tint or colour intended to be printed is made with indian ink, water
colour, or other substance mixed with water or other fluid, so that the
mixture is not of a greasy nature, on lithographic transfer paper (or
paper or other substance similarly used), coated with starch, gelatine,
paste, or other similar coating, by drawing with a pen, brush, or water
colour, pencil, writing, stencilling, or in any other convenient manner or
combination. The paper or other substance used is then damped on
the side not having thereon the sketch or copy, and the same is wholly
or partially transferred to the stone or plate by pressure in the same way
as a transfer of greasy lithographic ink is made, and after the stone
plate or block has been well washed with water, and if desired with spirit
of turpentine, the reversed sketch or copy is ready for the draughtsman's
or engraver's use, or if desirable it may be used by an engraver without
being washed.
AN IMPROVED LIFE BELT
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Hugh Jones at the Office of
the Commissioners of Patents, with his Petition, on the 13th
November 1872.
I, HUGH JONES, of No. 8, Church Yard Row, Newington Butts,
in the County of Surrey, do hereby declare the nature of the said
Invention for "AN IMPROVED LIFE BELT," to be as follows:-
The belt is composed of cork covered with sail cloth or other such
material, spaces being left to admit the arms, so that the cork shall
come up to the neck and above the shoulders. The form of belt and
dimensions suitable for a man of average size are shown on the plan
annexed. The cork is about one inch and a half in thickness, being
composed of two layers fastened together with pegs, twine, or otherwise.
It is cut into sections as shewn in the plan. The sail cloth is laid
on each side of the cork, and the two coverings of sail cloth are
firmly sewn together in all the divisions between the several sections
and also at the ends and sides, so as to preserve the cork from the
direct action of the water.
The sail cloth may be rendered waterproof, and an adhesive cement
may be used between the layers of cork if found advisable. Allowance

page_text: must be made on the outside of the belt in stitching the sail cloth
between the sections, so that the belt shall bend properly to the
body. One or two strong bands of webbing are fastened to the
sail cloth from end to end, to tie the belt around the waist. Straps
of the same material are attached to the upper side to go round the 5
neck and shoulders, and to keep the belt in its proper position.
•
By the form adopted allowing the cork to come up to the neck and
above the shoulders the head of the wearer is effectually prevented
from dipping under water even in a heavy sea, and by encasing the
cork in the sail cloth the life belt is rendered more durable; the cork 1
being thus protected from the action of the water will be more
certain to retain its buoyancy for a longer period.
IMPROVEMENTS IN THE DRIVING MECHANISM OF SEWING MACHINES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by John Millward at the Office
of the Commissioners of Patents, with his Petition, on the 31st
August 1872. A communication from abroad by Isaac Philip
Fishburn and Cyrus Davis Fishburn, both of Cinciunati, Hamilton
County, State of Ohio, United States of America.
I, JOHN MILLWARD, of No. 27, Paradise Street, Birmingham, in
the County of Warwick, Civil Engineer, do hereby declare the nature
of the said Invention for " IMPROVEMENTS IN THE DRIVING MECHANISM OF
SEWING MACHINES," to be as follows:―
This Invention relates to that form of mechanism used to drive
sewing machines in which the treadles are hinged at or near the heel of
the foot, and consists in connecting two treadles hinged at the heel as
above described by means of two pitmen to two cranks placed diametrically
opposite on the driving shaft.
This Invention also consists in the constructing of pitmen (applicable
alike to machines having single or double treadles) so that they can be
lengthened or shortened by means of a right and left handed screw
coupling or other equivalent adjusting mechanism, and thus allowing

page_text: the operator to change the angle of the treadle or treadles to suit bodily
deformities or the requirements of different individuals.
This Invention further consists in constructing the treadle or treadles
by which sewing machines are propelled with sector shaped edges or
openings vibrating upon knife edged fulcra, by which method friction
is reduced to a minimum and lateral motion of the treadles prevented.
By these means sewing machines are rendered much less irksome to
work, and less injurious to the health of operators than heretofore.
IMPROVEMENTS IN DAMPERS FOR DAMPING PAPER, OR FOR OTHER PURPOSES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by John Henry Johnson at the
Office of the Commissioners of Patents, with his Petition, on the
1st March 1872.-A communication from abroad by Jean Louis
Leboeuf, of Paris, in the Republic of France.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County
of Middlesex, Gentleman, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN DAMPERS FOR DAMPING PAPER, OR FOR
OTHER PURPOSES," a communication to me from abroad by Jean Louis
Leboeuf, of Paris, in the Republic of France, to be as follows:-
This Invention relates to a simple and effective apparatus for damping
the sheets of paper to receive copics of letters or other documents and
consists of a bottle provided with a tight fitting cork through which
cork a slot is cut for the passage of a piece of felt or other suitable
absorbent material. This bottle is to be filled or partly filled with water
and one end of the felt is caused to protrude beyong the cork whilst
the other is immersed in the water in the bottle. On passing the
protruding part of the felt lightly over the surface to be damped an
even and uniform application of moisture will be applied thereto. By
pressing the cork which is tapered more or less into the neck of the

page_text: bottle the felt will be more or less compressed and the degree of moisture
of the protruding portion will consequently be varied. The cork may
if desired be fitted with a metal cover and be encased on the sides with
india-rubber. A screwed or other metal cap is adjusted on to the neck
of the bottle so as to cover the cork and the felt when not required for
use.
IMPROVEMENTS IN TAPS AND APPARATUS FOR FLUSHING WATERCLOSETS AND IN TAPS FOR OTHER PURPOSES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by William Wright at the Office of
the Commissioners of Patents, with his Petition, on the 27th June
1872.
I, WILLIAM WRIGHT, of Sheffield, in the County of York, Plumber,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
TAPS AND APPARATUS FOR FLUSHING WATERCLOSETS AND IN TAPS FOR OTHER
PURPOSES," to be as follows:-
My Invention with reference to apparatus for flushing waterclosets,
has for its object the substitution of a suitably formed tap for valves,
thereby dispensing with the ordinary cranks, wires, and weights for
working the valves, and which tap can be worked in connection with any
cistern which need not be over the closet. The said tap consists of a
hollow plug with two compartments in it inserted in a pipe fitted in any
convenient place in the closet, which pipe is in communication with both
the supply pipe and the flushing pipe. The tap is formed with a longi-
tudinal partition which separates one side of the plug from the other.
On the one side are two apertures, whereof one communicates with the
supply pipe and the other with the flushing pipe, both of these apertures

page_text: leading into one compartment of the plug, which compartment is closed
at both ends. And on the other side of the plug there is an aperture in
the compartment communicating with the flushing pipe only, one end of
the compartment being closed and the other having an outlet to the pipe
leading to the basin.
When the plug is turned so as to be open to the cistern, water comes
down through the supply pipe and passes upwards into the flushing box
or "boot," and when the plug is turned half round it closes the passage
from the cistern and opens that from the flushing pipe to the basin.
And my Invention with reference to taps for other purposes, consists
in the use of a hollow plug with transverse partitions in it by which it is
divided into separate compartments, apertures being formed for the inlet
and outlet on opposite sides of each compartment. By this means the
tap or plug can be adapted for drawing off a different kind of liquid
through each compartment.
IMPROVED MEANS OF AND APPARATUS FOR MOVING VESSELS THROUGH THE WATER
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by John James Allingham at the
Office of the Commissioners of Patents, with his Petition, on the
13th February 1872.
I, JOHN JAMES ALLINGHAM, of 68, Hamilton Road, Everton, Liverpool,
in the County of Lancaster, do hereby declare the nature of the said
Invention for "IMPROVED MEANS OF AND APPARATUS FOR MOVING VESSELS
THROUGH THE WATER," to be as follows:-
This Invention relates to the employment of flaps, screens, or louvre
plates in suitable frames below the surface of the water for causing a
vessel to which the frames are attached to move; the progress or speed
being in proportion to the pitching or rolling motion, or both, given to
the vessel by the waves or the wind.
The mode which I propose to adopt is to take a strong piece of metal
having its thinnest edge in the direction of the vessel's motion and at
its bottom end, which should be immersed as deep in the water as is
consistent with proper strength and safety. A framing which carries
a series of flaps, blades, or plates whose action is to remain shut while
the vessel lifts, and being set at an angle to the bottom of the vessel
their action is to impel her forward. As soon as she commences to

page_text: fall as the wave recedes the blades or flaps open to a corresponding
angle in the reverse direction and allow the water to pass freely through,
at the same time they are impelling her in the same direction with a
force equal to the weight lifted.
The principal propelling effect is from the pitching motion of the
vessel, but in order to obtain a propelling effect from the rolling motion
I employ two more systems of blades exactly similar, one on the port
bow and the other on the starboard bow, the effect of which is not only
to take advantage of the lifting and falling of the vessel but also of the
rolling motion.
The frame can be affixed to any vessel or to a float which would be
agitated by the water to open and to close the blades as it falls and
rises.
AN IMPROVED CHIMNEY. COWL OB AERIAL ASPIRATOR
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by William Morgan-Brown at the
Office of the Commissioners of Patents, with his Petition, on the
9th December 1872.-A communication from abroad by John
Brunt, Paris, Engineer.
I, WILLIAM MORGAN-BROWN, of the Firm of Brandon and Morgan-
Brown, Engineers and Patent Agents, of 38, Southampton Buildings,
London, and 13, Rue Gaillon, Paris, do hereby declare the nature of
the said Invention for "AN IMPROVED CHIMNEY. COWL OB AERIAL ASPIRATOR,"
to be as follows:-
The object of this Invention is an improved chimney cowl or aërial
aspirator to produce an upward draft, suction, or aspiration in a
chimney by means of the wind or motion of the air. For this purpose
I make use of a cowl suspended on a fixed centre with a laterally
protruding pipe, the open end of which is turned by the wind in the
direction in which the wind is blowing; and in the part of the rotating
cowl directly opposite to the said open end I insert concentrically with
the protruding pipe a short pipe open at both ends, and the diameter
of which may be about one half of that of the said protruding pipe.
IMPROVEMENTS IN THE MANUFACTURE OF NEEDLE AND PERFUMERY BOXES OR CASES AND OTHER USEFUL OR FANCY ARTICLES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by John Garrett Tongue at the
Office of the Commissioners of Patents, with his Petition, on the
24th August 1872.-A communication from abroad by Théodore
Givry, Merchant, of Paris, France.
I, JOHN GARRETT TONGUE, of the Firm of Tongue & Birkbeck,
Patent Agents and Engineers, of 34, Southampton Buildings, Chancery
Lane, in the County of Middlesex, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF NEEDLE AND
PERFUMERY BOXES OR CASES AND OTHER USEFUL OR FANCY ARTICLES," to be as
follows:-
This Invention has for its object the application of glass known as
platinized glass or "glace platinée" to various fancy articles, such as
needle and perfumery boxes and cases and other similar articles, also
to toys, artistic, useful, or fancy articles made of paper, leather, metal,
or other material.
The platinized glass or "glace platinée" is either applied to the lid
or other parts of boxes, cases, or other articles according to this Inven-
tion, and when the lid is closed it serves as a mirror or looking glass,

page_text: but when open or placed before the light it is transparent, and photo-
graphed or other objects or images taken thereon or applied thereto are
distinctly seen or displayed.. Or the photographic or other image may
be enclosed between two glasses or be covered with collodion or varnish
or with transparent silicate for protection.
By these means when the lid of the box is closed, or the back of the
platinized glass is screened from the light, the effect of the camera
obscura will be produced, the glass serving as a mirror or looking glass,
the photographic or other image disappearing and only being rendered
visible by transparency when placed before the light.
IMPROVEMENTS IN PIPES FOR SMOKING TOBACCO
Year: 1872

page_text: .
PROVISIONAL SPECIFICATION left by Walter Deeble Boger at the
Office of the Commissioners of Patents, with his Petition, on the
25th January 1872.
I, WALTER DEEBLE BOGER, of 77, Chancery Lane, in the County
of Middlesex, and of Lincoln's Inn, Barrister at Law, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN PIPES FOR SMOKING
TOBACCO," to be as follows:-
My Invention has for its object the prevention of the passage of the.
oil of tobacco or nicotine juice from the bowl of the pipe to the mouth
of the smoker during the act of smoking, such oil or juice being highly
deleterious, as well as unpleasant. For this purpose, a box or chamber
is placed between the bowl and the mouthpiece of the pipe, which box
or chamber is filled with a plug or filter of tobacco (or if preferred
some other similar filtering material), in order to intercept the passage
of the oil of tobacco or nicotine juice, as it is extracted from the tobacco
in process of combustion by the heat in the bowl.
The box or chamber is made to open and close as required by dividing
it into two parts, which two parts when the box is closed are fastened

page_text: together either by screwing or otherwise, so as to prevent the access
of air to the box when closed otherwise than through the stem of the
pipe.
A plug or stopper of meerschaum, wood, or other suitable material,
perforated with holes, is inserted in the box or chamber at each end
thereof, the one plug or stopper being placed close to or against that
part of the stem which connects the box or chamber with the bowl,
so as to prevent the tobacco in the box or chamber from passing into
that portion of the stem, and the other being placed close to or against
that part of the stem which connects the box or chamber with the
mouthpiece, so as similarly to prevent the tobacco in the box or
chamber from passing into that part of the stem.
The filtering tobacco may be changed as often as is found requisite.
IMPROVEMENTS IN APPARATUS EMPLOYED IN THE MANUFACTURE OF THE CARBONATES OF SODA AND POTASH
Year: 1872

Year: 1872

page_text: PROVISIONAL SPECIFICATION left by John William Edmonds at the
Office of the Commissioners of Patents, with his Petition, on the
1st March 1872.
I, JOHN WILLIAM EDMONDS, of Camberwell, in the County of Surrey,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN OBTAINING MOTIVE POWER," to be as follows:-
I connect a lever at one end with a balanced lover communicating
with another lever, which last lever is acted upon by motive power in
any suitable manner;
all the above levers are caused to act in a
contrary direction to one another, but so arranged as to gain or loose
arca, that is to say, supposing the power communicated by the last lever
to the arm of the balanced lever be five, the power at the opposite
extremity will also be five, and the same power will be communicated
to the short arm of the first lever, and the power will of course be
multiplied according to the distance of the fulcrum from the arm which
is connected with the balanced lever.

which latter is arranged in such manner in several pieces so as to allow
of removing the core from the shuttle without injuring this latter.
Im- PROVEMENTS IN STUFFING BOXES FOR PISTON, VALve, and Pump RODS, WHICH MAY ALSO BE USED FOR OTHER SIMILAR PURPOSES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by David Robertson at the Office
of the Commissioners of Patents, with his Petition, on the 4th
. December 1872.
I, DAVID ROBERTSON, of Kilmarnock, in the County of Ayr, North
Britain, do hereby declare the 'nature of the said Invention of “Im-
PROVEMENTS IN STUFFING BOXES FOR PISTON, VALve, and Pump RODS, WHICH MAY
ALSO BE USED FOR OTHER SIMILAR PURPOSES," to be as follows, that is to say :—
This Invention, which relates to improvements in the arrangement or
construction of stuffing boxes used for the purposes of packing piston,
valve, and pump rods, and which may also be employed for other similar
purposes, consists, in constructing the stuffing box with a movable ring
at the bottom, from which studs project through a plate or its equi-
valent at the outer end of the stuffing box. Between the upper part of
the box and the movable ring at. its lower part, a hollow gland is
situated, in the hollow of which the packing is contained, and an.
annular space is formed in the movable ring into which the inner part
of the hollow gland passes. By tightening the nuts on the studs
projecting from the movable ring, it is drawn outwards, so that by means
of this improved stuffing box the packing is at all times compressed
from both its ends.
IMPROVEMENTS IN OR APPLICABLE TO CARDING ENGINES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by William Henry Mitchell and
Ralph Jordinson at the Office of the Commissioners of Patents,
with their Petition, on the 23rd December 1872.
WC, WILLIAM HENRY MITCHELL, Card Maker, and RALPH JORDIN-
SON, Woollen Merchant, both of Huddersfield, in the County of York,
do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN OR APPLICABLE TO CARDING ENGINES," to be as follows:-
The object of this Invention is to prepare the wool or other fibrous
substance as it comes off the "scribbler" so as to feed the same to the
"carder" in more even or uniform manner, and the improvements
consist of framework on which rollers supporting two endless travelling
aprons, side by side, to receive the wool or other fibres from the
scribbler or first carding engine in two or more separate sheets or
films, and by a traverse motion of one part of the said aprons to
deliver the material to another endless travelling apron which winds
the same upon bobbins, which arc thence removed to an intermediate
machine" or apparatus for feeding the carder; the said intermediate
machine or apparatus comprises a series of rollers having endless aprons.
thereon, the top apron by frictional contact with the material or film

page_text: on the bobbin, which is received by and works in supports immediately
over and upon this apron causing the bobbin to revolve and give off
the material, which is thence guided by another endless apron to the
creeper sheet and conveyed to the carder.
A traversing or "to-and-fro" motion is imparted to the rollers and
endless aprons so as to deposit the film upon the creeper sheet in
layers or laps, in such manner as that the thick side or inside portion
of the film will be deposited immediately over or upon the opposite or
thin side of the film, and so the material will be evenly fed to the
carder; the second bobbin on being applied to the "intermediate "
above described will be deposited with the thick portion of the film
thereon in the same position in the supports; but the motion of the
contact apron will be reversed in order that the material may be wound
therefrom the more readily, and that such material may be deposited on
the creeper uniformly with that from the first or preceeding bobbin,
which is best secured by the films being drawn from the bobbins in
opposite directions. The reversing the motion of the endless sheet
may be accomplished by pulleys and cord, and a tension pulley, or by
means of reversing gear. The traverse of the endless sheets and film
are effected by means of pegged belts, or chain gear and pulleys; the
pulleys and endless sheets being driven by means of gear applied to a
square shaft parallel with the roller's ends.

both of the Hornsey Iron Works, Hornsey Road, in the County of
Middlesex, and WILLIAM GUEST, Machinist, of 83, Great Saffron Hill,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN MACHINERY FOR BRAIDING WHIPS OR OTHER
ARTICLES," to be as follows:-
Our Invention consists of the addition to the ordinary braiding
machine of a number of pairs of wheels and discs gearing outside
the usual circle of wheels and discs, and of conductors which can be
reversed so as to let one pair or more of bobbin carriers and their
strands go in or out of work when required according as the article to
be covered may be thicker or thinner.
In order that our Invention may be clearly understood we will
proceed to describe the same with the aid of the accompanying Drawing,
which is a sectional plan of a machine constructed according to our
Invention.

page_text: A, B, C, D, E, F, G, and.H, show the circle of discs geared together
below by wheels which are in the ordinary braiding machine; and
J K, L M, NO, P Q, denote four additional pairs of discs geared by
their wheels below with the circle. Now if the conductors r, s, t, and u,
were all in the same relative positions, shewn at r, the circle of discs
A, B, C, D, E, F, G, H, would move the eight pipes a, b, c, d, e, f, g,
and h, which hold the bobbin carriers and their strands in the ordinary
way to form a braid, whilst the pipes in the outside discs would simply
travel round and round their discs. But when an additional pair of
strands is to be put in, all the operator has to do is to move one of
the conductors, when clear of the pipes, in the same relative position
shewn at s, t, and u, until all the pipes and strands (in this case sixteen)
are at work.

page_text: PROVISIONAL SPECIFICATION left by Henry Page at the Office of
the Commissioners of Patents, with his Petition, on the 17th
December 1872.
I, HENRY PAGE, of Market Buildings, Mincing Lane, in the City
of London, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF PAPER PULF OR HALF STUFF," to be as
follows:-
This Invention consists in manufacturing paper pulp or half stuff in
the following manner :-I take spent hops either alone or in combination
with any other known paper making material or materials, and place
them in a suitable boiler and mix them with a solution of caustic soda
or other suitable alkali at a strength of two to ten degrees Baumé.
Into the said boiler I admit steam of a pressure below 90 pounds to the
square inch for the purpose of boiling the said spent hops, and continue
the boiling for about six hours, more or less, according to the strength of
the alkali and the pressure of steam in the boiler.
The pulp may be freed from the alkali by washing, and then be
A NEW SOLUTION FOR JOINING VULCANIZED INDIA-RUBBER
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Henry Myerns at the Office
of the Commissioners of Patents, with his Petition, on the 80th
April 1878.
I, HENRY MYERNS, of Liverpool, in the County of Lancaster, do
hereby declare the nature of the said Invention for “A NEW SOLUTION
FOR JOINING VULCANIZED INDIA-RUBBER," to be as follows (that is to say) :—
manner,
This Invention consists in a solution for cementing or joining vul-
canized india-rubber, causing it to adhere in a firm and permanent
and may be used for repairing articles manufactured “of vul-
canized india-rubber, such as water pillows, water beds, hose pipes,
"North British cloths," galoshes, and so forth; and is produced in the
following manner:-Take (say) three parts of Stockholm pitch, three
parts of American rosin, eight parts oil of turpentine, six parts best bottle
india-rubber, and twelve parts best mineral naptha, and dissolve them
together by gentle heat, or one or more of the solids may be dissolved
seperately, after which add the requisite quantity of the oil of turpentine
and mineral naptha thereto.

page_text: Should the mixture be too viscid for the use intended a little additional
oil of turpentine or mineral naptha, or both, may be added to obtain the
required consistency.
In applying the mixture coat the two surfaces to be joined together
and then bring them into contact with each other, then allowing them :
to remain untill they are sufficiently dry, when perfect adhesion of the
several parts will be found to have taken place.
A textile fabric coated with this composition may be applied to
vulcanized india-rubber goods for the purpose of patching or strengthening.
In some cases I prefer to roughen and clean the surfaces to be joined 1
with sand or emery paper, pumice stone, or other graining substances,
such as glass, grains of metal, and so forth.
Turpentine previous to distillation may be used in place of the rosin
and oil of turpentine either in whole or in part.
IMPROVE- MENTS IN MACHINERY OR APPARATUS FOR CUTTING SPLINTS
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Edmund Pace at the Office
of the Commissioners of Patents, with his Petition, on the 5th
February 1872.
I, EDMUND PACE, of Bow Common, in the County of Middlesex,
do hereby declare the nature of the said Invention for " IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR CUTTING SPLINTS," to be as
follows:-
The Invention has for its object improvements in machinery or
apparatus for cutting splints, and relates to that class of machinery for
which Letters Patent were granted to Frederic Tillett, dated March 23,
1859, Number 746, in which a series of lancets or scoring knives are
caused first to cut or score the wood to the depth of a splint, and then
a slicing knife is made to act at or about right angles to the path of
such lancets or scoring knives to cut off the splints from the wood.
Instead however of operating the lancets or scoring knives, and the
slicing knife as described in Tillett's Specification, I prefer to operate the
slicing knife by means of a lever connected thereto at one end, and
operated by a crank from the main shaft, whilst I prefer to operate the

page_text: frame carrying the scoring knives or lancets by an eccentric on the same
shaft.
Now my improvements consist in so mounting the frame of the
lancets or scoring knives that by means of a detent fixed thereto, and
coming at the required time when travelling in one direction in contact
with a stop or projection on the frame of the machine, to cause the
lancets or scoring knives to protrude above the surface of the plane in
which the slicing knife acts to cut the wood, whilst in travelling in the
other direction such detent comes in contact with another stop or
projection to cause the lancets or scoring knives to retire beneath the
surface of such plane. Or the frame of the scoring knives or lancets"
may be mounted in and controlled by suitable guides to cause the
lancets to come into and out of position for work as may be required.
As the splints are cut they pass through and out of a prolonged
mouth piece to which is jointed a long covered guide or trough, which
is open at the unattached end and rests upon a suitable support. To
this end the splints gravitate, allowing them readily to be gathered
together and removed.
IMPROVEMENTS IN AND APPLICABLE TO FIRE-BARS
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Albert Toller and Allen Smyth
at the Office of the Commissioners of Patents, with their Petition,
on the 7th December 1872.
We, ALBERT TOLLER and ALLEN SMYTH, both of Liverpool, in the
County of Lancaster, Engineers, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN AND APPLICABLE TO FIRE-BARS," (to be as
follows:-
Our Invention consists in forming fire-bars, each with a passage or
passages therethrough in the direction of its longitudinal axis when
each such fire-bar, placed from front to back of a furnace, is formed
with helical projections on its outer surface, and is caused to rotate on
its axis.
The advantages secured and the means whereby the same are attained
are herein-after set forth.
First. As means for supplying a blast of air in a furnace we connect
the ends of each said rotating fire-bar to an air blast pipe, and form
small holes through the bars so as to admit air from the internal passage
amongst the fuel.

page_text: Second. As means for heating water, such as feed water for boilers,
we connect each of the ends of the said rotating fire-bars to water-
supply and take-off pipes, the air holes leading into the furnace being.
in this case omitted.
Third. As means for admitting air into the furnace, and for heating 1
water, that is to say, for attaining the advantages of the above first and
second parts we construct each bar both with an air passage and
openings, and a water passage, the water passage is preferably contained
through the helical surface projections.
Fourth. As means for attaining the advantages mentioned under the
above third head, we place an air and a water bar alternately or other-
wise.
Fifth. As means for causing the air blast to pass up through the fire
instead of down we fit a plate close under the bars in the ash-pit,
thereby forming a solid bottom to the furnace, or we close the ash-pit
for the same purpose and dispense with the said plate.
Sixth. As means for supporting the fuel along the sides of the
furnace, or between the bars if necessary, we make use of chain bars
travelling from the front at the same rate as the helical projecting
surfaces.
IMPROVEMents in StuppinG BEDS, MATTRESSES, PALLIASSES, CUSHIONS, PILLOWS, &C. WITH GROUND OR GRANULATED CORK, OR OTHER LIGHT BARK OR WOOD
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Edwin Taylor at the Office
of the Commissioners of Patents, with his Petition, on the 24th
September 1872.
I, EDWIN TAYLOR, of 22, Woodstock Road, Finsbury Park, Holloway,
in the Parish of Hornsey, London, do hereby declare the nature of the
said Invention for "IMPROVEMents in StuppinG BEDS, MATTRESSES, PALLIASSES,
CUSHIONS, PILLOWS, &C. WITH GROUND OR GRANULATED CORK, OR OTHER LIGHT
BARK OR WOOD," to be as follows :—
I grind cork or any other light bark or wood to a fine powder, or reduce
it into a granular state, and with this I fill the tick or canvass cases to
make them into beds, mattresses, cushions, pillows, &c. Beds so made
are soft, elastic, durable, and inexpensive, and they are not affected by
damp.
AN IMPROVED MATCH Box OR CASE FOR AUTOMATICALLY LIGHTING WOOD OR WAX MATCHES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Arthur Charles Henderson at
the Office of the Commissioners of Patents, with his Petition, on
the 24th December 1872.-A communication from abroad by
Jules Saint Anne, Merchant, of Bordeaux, in the Department of
Gironde, France.
I, ARTHUR CHARLES HENDERSON, of the Firm of Henderson and
Company, British and Foreign Patent Agents, of No 31, Charing Cross,
in the County of Middlesex, do hereby declare the nature of the said
Invention for "AN IMPROVED MATCH Box OR CASE FOR AUTOMATICALLY LIGHTING
WOOD OR WAX MATCHES," a communication to me from abroad by Jules
Saint Anne, Merchant, of Bordeaux, in the Department of Gironde,
France, to be as follows:-
The match box referred to consists of a cylinder closed by a cap fixing
bayonet fashion, inside this cap is a kind of spring claw whose striated
surface effects the lighting of the match as it passes quickly out through
the сар. All the mechanism in connexion with the box is at its lower
part, and consists of two discs or rundles, the upper one fixed, which
receives a segment or blade in a suitable groove, a lateral axis of which

page_text: allows it to pivot downwards on a metal piece soldered to the cylinder;
the lower extremity of this same axis is flattened and acts as a spring to
the segment referred to, when it is lifted or raised by the second or
lower rundle, which latter is actuated by turning a plate or fly wheel to
which it is attached by pins. This same rundle is hollowed to receive a
spiral spring wound round a screw which unites the two rundles whilst
serving as pivoting axis to the lower one.
Supposing a certain quantity of matches placed in the box, in turning
the fly wheel from left to right a second blade is drawn. along in its
movement, whilst the first named one is simply raised by the action of
the spring at the flattened end of the axis in connection with the first
named blade, and continuing to turn the fly, the second blade or
segment always withdraws from, whilst that of the first returns to, its
point of departure. In this position and in the space comprised between
the two segments or blades, a match arrives by agitating the box, which
after loosening the fly (led naturally by the effect of the spiral spring) is
pushed and directed by the second segment to occupy the kind of case
formed by the superposition of the two segments, so that the stick of the
match is received by a holder in connection with an external button,
which pushed smartly in a groove on the cylinder or box causes the
head of the match to pass through the cap, when it ignites by friction
against the spring claw with striated surface. By raising a shield by
sliding it up the cylinder the light cannot be extinguished by the wind;
two small tenons prevent the shield leaving the cylinder.
AN IMPROVED EXHAUSTER AND BLOWER FOR GAS AND OTHER AERIFORM BODIES
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by William Foulis at the Office of
the Commissioners of Patents, with his Petition, on the 20th May
1872.
I, WILLIAM FOULIS, of Glasgow, in the County of Lanark, North
Britain, Civil Engineer, do hereby declare the nature of the said
Invention of "AN IMPROVED EXHAUSTER AND BLOWER FOR GAS AND OTHER
AERIFORM BODIES," to be as follows, that is to say :—
This Invention which relates to an improved arrangement or con-
struction of apparatus for exhausting or blowing gas or other aeriform
bodies, consists of a pair of hollow cylinders through which a revolving
shaft passes, and on those portions of this shaft which are situated
within the cylinders, eccentric revolving pistons are fixed in positions
diametrically opposed to each other. A chamber is formed on each
cylinder, and which contains a hanging valve or abutment, the extreme
or terminal edge of which is always in contact with the eccentrically
revolving piston; thus a constant separation is maintained between the
pressure and exhaust sides of the apparatus, as the hanging valve follows
the motion of the eccentrically revolving pistons. On either side of the
chambers containing the hanging valve ducts or passages are arranged,

page_text: these being respectively drawing or exhausting and forcing passages.
The motions of the hanging valve are caused to follow truly that of the
eccentric pistons by guide cams situated on that portion of the revolving
shaft which extends outside or beyond the cylinders, being coupled
thereto by suitable levers; and by means of the diametrically opposed
positions of the said pistons the exhausting or forcing action is rendered
continuous.
AN IMPROVED METHOD OF TREATING GALVANIZED IRON SCRAP, AND THE UTILIZATION OF THE PRODUCE
Year: 1872

page_text: PROVISIONAL SPECIFICATION left by Arthur Thomas Becks at the
Office of the Commissioners of Patents, with his Petition, on the
18th May 1872.
I, ARTHUR THOMAS BECKS, of Aston, near Birmingham, in the
County of Warwick, Iron Merchant, do hereby declare the nature of
my said Invention for "AN IMPROVED METHOD OF TREATING GALVANIZED
IRON SCRAP, AND THE UTILIZATION OF THE PRODUCE," to be as follows (that is
to say) :—
My Invention consists in removing the zinc deposited on galvanized
iron scrap (which is iron coated with zinc), and utilizing the iron residue
so as to be suitable for remanufacture as ordinary scrap iron. This I
effect by immersing the galvanized iron scrap in an acid solution of
tin, the acid of which acting upon the surface of the galvanized iron
scrap will dissolve the zinc therefrom, and thereby precipitate the tin
held in the solution in a metallic form, after which the zinc solution
may be drawn off and the zinc precipitated by any of the well-known
processes.
