An Improved Appliance for Holding Corks in Bottles.
I, ELIZA ANTHONY, of Morfa House, Kidwelly, Carmarthenshire, Grocer do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
This invention consists in an improved appliance for holding down corks in
bottles. It is especially intended for use on bottles charged with mineral and
aerated waters and effervescent wines and like liquids.
The appliance consists of a band or bar of iron or steel shaped to form a curved
spring clip for clipping on the bottle neck. Towards one end the spring clip is
cranked or turned so that the said end extends outwards at a right angle, or
approximately so. Connected to or slung on the spring clip is a strap of tin or
other suitable metal having at the front a row of holes. When the appliance is
placed on a bottle the spring clip embraces the bottle neck, and the perforated strap
having been pulled down on the cork is retained by engagement of the cranked end
of the spring clip with one of the holes in the said strap. The cork is accordingly
prevented from becoming removed from the bottle until the strap is released.
Referring to the accompanying sheet of drawings, Fig. 1 represents a part of a
bottle neck having applied thereto a cork-retaining appliance made according to
this invention. The appliance is shown in side view. At Fig. 2 is represented a.
front view of the appliance. Fig. 3. represents a plan.
Acting as a spring clip about the bottle neck, is a band or bar a of iron or steel..
Towards one end this band or bar a is cranked or turned outwards to form a pin a¹.
Connected to or slung on the clip is a strap b of tin or other suitable material.
This strap b has a row of holes extending to a suitable distance upwards from near
the lower end of the strap. When the band or bar a has been clipped on to the
bottle neck the strap is pulled down and is retained by the pin a' which for that
purpose is passed through one of the holes in the strap b. The cork is thus
prevented from flying out of the bottle neck under pressure of gas or air contained
in or associated with the liquid with which the bottle is charged.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
An appliance for holding down corks in bottles; said appliance consisting of a
spring band or bar such as a shaped to act as a spring clip about the bottle neck,
and a perforated strap such as 6 connected or looped at one end to the clip, the
latter having a cranked or turned end a' for engagement with the holes in the strap.
when the strap has been brought over the cork, substantially as herein before
described with reference to the accompanying sheet of illustrative drawings.

Improvements in Obtaining Pure Concentrated Nitric Acid from
Dilute or Impure Solutions.
I, Dr. FRIEDRICH VALENTINER of The Chemische Fabrik Valentiner and
Schwarz Leipzig-Plagwitz in the Empire of Germany, Chemical Manufacturer, do
hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement :-
In the German Patent No. 63207 is described a process for the preparation of
nitric acid through the decomposition of sali petre by means of sulphuric acid in a
vessel deprived of air. It has now been proved that nitric acid of any degree of
concentration and even such as has already been in use, that is to say, waste acid
for instance can be recovered as high strength perfectly pure acid by re-distillation
with concentrated sulphuric acid in vessels free from air or at least under reduced
atmospheric pressure.
By means of this new process it is possible to convert all dilute acid, obtained by
any method in use at present and which owing to its low degree of concentration
is often regarded as a by-product difficult to utilise, into easily saleable high
strength HNO. If, by way of example, a mixture of 800 kilos. H2SO with
1200 kilos. of impure HNO, of the specific gravity of 1-40 is subjected to distil-
lation in a partial vacuum, the temperature need not rise above 100° Centigrade
and consequently nearly all the water will be retained by the sulphuric acid
together with the other impurities present whilst pure concentrated HNO3 of 94
to 95% monohydrate will distil over and collect in the receivers.
Apparatus applicable for the above process is described in German Patent
No. 63207.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
Process for the obtaining of concentrated pure nitric acid consisting essentially
in re-distilling dilute nitric acid obtained from any source in vessels partially or
entirely deprived of nir.

I, JAMES ROSSDALE trading as J. R. Dale & Co. of 125 Gloucester Road
South Kensington in the County of London Ladies Tailor, do hereby declare
the nature of my said invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:--
This improved cycling skirt for ladies use embodies a pair of knickerbockers.
It is shewn in rear view in Fig. 1 of the accompanying drawing, in which dotted
lines represent the knickerbockers, and in sectional elevation in Fig. 2.
The front portion of the skirt A and the knickerbockers B are made as usual
and attached to the same waistband.
At the back however the skirt has two full pleats or folds, a a so gathered on the
waistband as to meet when the wearer is standing. Internally the skirt is at either
side, by the edges a¹ of the material forming the pleats a a attached to the seat
seam and the leg seam of the knickerbockers B.
When the wearer sits down on the saddle of a velocipede the natural action
of the body causes the folds a a to separate so that the garment offers all the
convenience of a bifurcated garment and nevertheless, when the wearer is walking,
is as becoming as an ordinary skirt.

aware that it has before been proposed to make a riding habit having its skirt attached
along one side of the inner or leg seam' of the right leg of the breeches, or of the
trousers and to the 'seat seam' and along the other side to the inner or 'leg seam
of the left leg and to the 'seat seam,' and I therefore make no claim to attaching
a skirt in such a manner to knickerbockers except when the skirt is made with two
full pleats or folds so gathered on the waist band as to meet when the wearer is
standing, as above specified, and I declare that what I claim is
A cycling skirt for ladies use divided from top to bottom at the back and united
with a pair of knickerbockers at the waist and along the leg seam of the knicker-
bockers as set forth and illustrated in the accompanying drawing.

Improvement in the Backs of Chairs and similar Articles of
Furniture.
I, JASPER WETTER, Patent Agent, of 433 Strand, in the County of London,
do hereby declare the nature of this invention, a communication from the Firm
of Jacob and Josef Kohn, Manufacturers, of 24 Elisabethstrasse, Vienna, in the
Austro-Hungarian Empire, to be particularly described and ascertained in and by
the following statement:-
Plates of bent wood or veneer have hitherto been employed for the manufacture
of chair-backs, but only so as to fill up the back frames or the space between
the upward extensions of the rear legs.
The present invention has for its object, to form the back of a chair from a
massive bent wood-plate or from several layers of veneer (crossing each other
alternately) without the necessity of using a frame or of extending the rear legs
above the seat to form part of such a frame. For this purpose I produce the
necessary rigidity by the shape of the massive wood plate or veneer plates and fix
it to the scat by screws or by letting it into the seat, or by any other suitable
means.
The accompanying drawing is a perspective view of a chair embodying the
present invention. a indicates the back of the chair and b the seat.
If the lower part of the back a', is made to extend forward on the right and
left, so as to partly enclose the seat, the braces which are now used in bent wood
chairs for strengthening the connection between the back and the scat, may be
dispensed with.
In this case the plate from which the back a is to be made, is cut out in such a
manner, that the base is wider than the middle part, and forms a pair of curved
wings or arms extending right and left from the main part, which may have any
convenient ornamental outline.
When the flat plate thus shaped is bent into the required concave shape, the
said wings a¹ are bent forward so as to enclose the rear part of the seat and follow
the outline of the same. The upper edge of each wing forms preferably a double
curve, as shown, being concave at its wide base, where it joins the main body, and
convex near the narrow outer extremity, and the two curves may be joined together
by a short straight line at an acute angle to the base.
If desired, the back may have an ornamental opening or perforation near the
top, or several such openings.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :
1. In chairs or similar articles of furniture, a back made entirely of a bent
solid plate of wood or veneer, substantially as described.
2. In chairs or similar articles of furniture, a back made entirely of a bent solid
plate of wood or veneer, and having at its base lateral extensions adapted to
serve as substitutes for braces, substantially as described.

Improvements in Hay-chopping Machines for the Removal of Dust.
I, GEORGE KELSEY of 13 Clarke Square, City of Sheffield Implement Maker
do hereby declare the nature of my invention to be as follows :-
My invention has for its object to extract and carry away the dust that is always
found in hay and the like, and that is shaken loose and set at liberty by the action
of chopping, and to accomplish this desirable object in a simple, efficacious and
cheap manner.
In carrying out the invention, I enclose the chopping machine in a casing having
a shoot or other outlet for the chop to escape from, preferably situated at the
bottom of the cutter casing, and from the top of the casing I carry the outlet for
the dust which inay terminate either in a box, room, or in the open air. The mouth
of the outlet is close above the revolving blade carrier, and is closed by a perforated
plate, or its equivalent to prevent the passage of the cut hay.
A blowing fan of any suitable construction is arranged to force air into the
lower part of the casing, which permeates or passes through the body of falling
chop and carries the light dust and any foreign floating particles upwards through
the perforated plate and outlet pipe before described.
The revolving blade carrier causes sufficient motion of the air in the upper part
of the casing to keep the surface of the perforated plate free from clogged dust.

Improvements in or relating to Friction Disks.
I, JOHN THOMAS GODFREY, of 80 Industry Road, Darnall, Yorkshire,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
My invention relates to friction disks of the kind described in Patents No. 263
A.D. 1863, and No. 3093 A.D. 1865, and my invention consists in tapering the
peripheries of one or both faces of the disks thereby setting back part of the
working face or faces, as represented in the annexed drawings, such taper or angle
in length and depth varying as circumstances may require.
When disks are used as a retarding frictional appliance for revolving shafts and
more especially when in connection with other gearing it is well known that they
slide over one another more easily according as they wear and as the machine with
which they are connected finds its working bearings. Therefore when made as
described in the aforesaid Specifications, riz.: with the working faces made
parallel right to the periphery, they either work too hard when new, or too easy
when worn.
My object is to overcome this defect by making the faces so that they will
increase in diameter and working frictional radius according as they wear away on
the face or faces.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I wish it to be understood that I
do not limit my claim to the exact shapes of taper shown in the drawings which
can be varied according as circumstances may dictate but I declare that what I
claim is :-
In friction disks of the description named, the method described of increasing
the frictional surface in any predetermined proportion, as and for the purpose
hereinbefore described.

I, EDWARD WILLIAM IVES of No. 2 Strand Derby in the County of Derby
Civil Engineer, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
The object of my invention is to make certain improvements in the method of
extracting the precipitated sludge or solids from sewage or foul or waste waters
from the bottom of precipitating tanks having inverted coned shaped bottoms and
for this purpose instead of the apex of the inverted cone terminating in a sump
I cut off the apex of the inverted cone thus forming a flat surface. Upon this flat
surface I place a cone and over this cone another larger one connected at its apex
with a suction pipe. A space is left between the two cones for suction of the sludge
from the bottom of the tank the bottom of the outer cone being shorter than the
inner cone.
In order that my invention may be more readily understood I have caused to be
annexed to this Specification a sheet of drawings the figures and letters of reference
marked thereon will be hereinafter referred to.
Figure 1, represents a vertical section of the bottom of a tank with an inverted
cone shewing the suction cones.
Figure 2, is a plan of same looking down upon it.
The drawing illustrates a cylindrical inverted cone bottom to tank the outer
casing A being of metal, brick, concrete, wood, or other suitable material, the
suction cones B and C, being of metal or wood or other suitable material. D is a
suction pipe, E is a space between the cones for the purpose of suction of the
sludge by means of pipe D, G is a diamond shaped spreader circular on plan so
placed to ensure the sludge being sucked from the sides of the cones in an uniform
manner all round the periphery of the outer cone, & to privent the suction taking
place along the line of least resistance F to the top of the sludge at H.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
1. The perfect removal of all deposited sludge or solids from a precipitating tank
having an inverted coned shaped bottom without leaving any of the sludge adhering
to the sides of the cones.
2. A thicker sludge than is now extracted by means of a straight cylindrical pipe,
or a pipe terminating in a single cone bottom.

Park, London; EWALD FISCHER 25 Listria Park, Stoke Newington London
Engineer, and CARL TUNSTILL JOHN OPPERMANN 2 Wynyatt Street,.
London E.C. Electrical Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to an improved process of effecting the amalgamation of
gold with mercury the object being to more effectually amalgamate what is known
more particularly as float gold in ores, or very finely divided goid.
In order to ensure the amalgamation of the gold we cause the vapour of mercury
at a suitable temperature to be brought into contact with the wet or dry crushed
ore either directly under the stamps which crush the ore or after the crushed ore
has been removed from the stamps. The mercury vapour may be conveyed by
suitable pipes, from a retort in which the mercury is heated to the crushed ore so
that the vapour of mercury is brought into contact with the gold and amalgamation
effected, the mixture being afterwards treated in any convenient way for extracting
the gold from the amalgam such as by electrolytic action.
The vapour may be brought into contact with the crushed ore by causing the vapour
to be blown upon or through the ore by means of steam under suitable pressure after
the ore has been crushed. The vapour of mercury is thus mixed with steam and we
make no claim to the use of mercury vapour for the purposes of this invention unless
it be so mixed.
In some cases we find it convenient to mix the vapour of mercury with ammonia
gas or other suitable reagent which facilitates the amalgamation when the gold is
coated with foreign bodies or substances.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed; we declare that what we
claim is :-
1. In amalgamation processes, the use of vapour of mercury with steam mixed
therewith, substantially as described.

Process of Manufacturing Carbon for Filtering and other Purposes.
We, OTTO WILHELM BRANDENBURG, Merchant and FRIEDRICH HERMANN
POTT, Chemist, trading under the Firm of Otto Brandenburg & Co. both of
44 Chausséestrasse, Berlin, do hereby declare the nature of our said invention
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
This invention relates to a process of manufacturing carbon, especially adapted
for the filtration of water, but which may also be used for numerous purposes in
the chemical industry.
According to this invention the carbon is manufactured in the following manner:
Coagulum or gore, flesh, glue or other organic substance is heated to about 1270° F.,
the residuum being then treated with concentrated sulphuric acid. All air is
excluded during such heating, which is preferably effected by means of surperheated
steam and may be accelerated by adding an alkali or alkaline earth. After
cooling the mass to about 230° F., it is reduced to small pieces and put into con-
centrated sulphuric acid; the function of the latter is to dissolve the impurities or
admixture and to convert all organic constituents into carbon i.e. to carbonize the
whole mass.
'
The resulting pulp or mass is now diluted with water and the carbon then
obtained from same by decantation or filtration. If necessary or desired, a further
purification of the carbon may be effected by boiling same with hydrochloric acid.
The washed carbon is finally reduced to a fine powder by passing same between
rollers or in any other suitable manner, in which state it is an effective filtering
agent.
Carbon produced in the above described manner remains exceedingly loose or
open and is remarkable for its purity and diffusibility. The well known chemical
and mechanical property of carbon is proof of same being an exceedingly fine
agent for filtering purposes, while the carbon produced as herein set forth possesses
the further excellent quality of being highly diffusive.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Process of manufacturing carbon for filtering purposes consisting in heating
coagulum, gore flesh glue or any other organic substance, to about 1270° F. and
treating the residuum with concentrated sulphuric acid, substantially as described.

Improvements relating to Velocipede Saddles.
I, CARL RAUHE, Dentist, of Königsallee 4, Düsseldorf, in the German Empire,
do hereby declare the nature of this invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates more particularly to saddle springs and is illustrated by
the accompanying drawings, of which
Fig. 1 is a side view of a bicycle provided with my improved saddle.
Fig. 2 is a side view of the saddle and the adjoining parts of the bicycle frame
on a larger scale, and
Fig. 3 is a plan of the saddle spring corresponding to Fig. 2.
Fig. 4 is a detail view.
The saddle is pivoted in front on a hinge pin s and supported at the back by a
spring, which is not rigidly connected with the saddle. The said spring may be
made of steel wire, flat steel or other suitable material, and may be fixed to the
cycle frame by any convenient means. It forms a single or double horse-shoe, as
represented by the drawing, and the extremities f¹ of the same are located under a
friction roller secured to the saddle frame, as shown by Fig. 3. Instead of such
a roller a sliding piece may be employed.
Owing to this arrangement of the spring, the saddle is very elastic, and does not
produce undue pressure even after prolonged riding.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
The combination of a velocipede saddle hinged in front, with a saddle spring the
upper extremity of which (f) is not rigidly connected with the saddle but supports
a friction roller (r) or a sliding piece secured to the saddle, substantially as
described.

Improvements in the Edging of Hat Leathers or Bands.
I, EDWARD JOHN SHARP, of 79, Shaw Heath, Stockport, in the County of
Chester, Helmet Manufacturer's Manager, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to improvements in the edging of hat leathers or bands.
Heretofore hat leathers or bands have been edged by simply turning the upper
edge over.
The object of my invention is to form the said edge separate from and suitably
attaching it to the hat leather or band which enables me to make such edge
different in colour and material to that of the hat leather or band itself which
greatly improves its finish and appearance and also tends to retain it in shape.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings which represent in perspective and at
an enlarged scale several ways in which my invention may be carried out.
To this end, according to one form of my invention and referring to Fig. 1,
I form the edge a from a strip of leather, leatherine, fabric, (say silk, linen or
cotton) or of fabric covered with paper or of any other suitable material. The
said strip I gum or otherwise fasten around a thin core c, which may be of cord,
wire, cane, or of any other suitable material, the edges being allowed to project
therefrom so as to form flanges a'. The cored edge a is then made to abut against
the edge of the hat leather or band band the flanges a' guined or otherwise fastened
to the back of the latter.
I may sometimes use the edging described without a core and produce its tubular
appearance by passing it through rollers as will be readily understood.
According to another form of my invention and referring to Fig. 2, I may bind
the edge of the hat leather or band b with a strip of suitable material as shown,
the latter with the hat leather or band between being afterwards passed through
rollers which press and give it the appearance of a cored edge.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improved method of edging hat leathers or bands consisting in forming the
edge separately from the hat leather or band and attaching the same thereto all
substantially as and for the purpose set forth.

page_text: I, HUGH CAMERON, of 431 Victoria Road, Crosshill, in the City of Glasgow,
Commercial Traveller, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object to better adapt table forks for use in lifting
meat and vegetables to the mouth. To that end I form the prongs of the fork
with their points bent or set over at an inclination so that they are more easily
inserted into meat, and when used for lifting vegetables or other soft substances
the bent ends of the prongs prevent such substances falling off the fork.
The handle end is turned back instead of forward so as to resemble a spoon
handle and to enable it to be better held between the thumb and fore-finger in
raising the fork to the mouth.

An Improvement in Pie Collars.
ALEXANDER MULLORD, Manufacturing Stationer, 1, 2 and 3 Penn Street,
Hoxton, London, N., do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to the ornamenting of pie collars by perforating. I first
cut plain, printed or embossed paper or other material into the proper lengths and
widths required. I then by the aid of dies, rollers,. chisels or other suitable tools
perforate a design on the same or I perforate the paper or other material first and
cut it up after. I then fold the paper or other material in the usual way to
produce a pie collar or I perforate the design on the pie collar after it is folded or
made up.
I do not confine myself to any particular design or pattern as from the nature
of the invention great scope is afforded for ornamentation by perforating.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
An improvement in pie collars by ornamenting them with perforations.

I, ALEXANDER PAUL BAUER, of 6 Hallerstrasse, Hamburg, in the Empire of
Germany, Engineer, do hereby declare the nature of this invention, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention relates to a two-jaw chuck actuated by a right and left handed
screw.
In the accompanying drawings
Figure 1 is an elevation of a chuck constructed in accordance with my invention,
the upper part of the figure being a half back view with the part a of the chuck
removed, and the lower part of the figure a half front view,
Figure 2 a sectional view taken on the line x-x of Figure 1, and
Figure 3 a half sectional view taken on the line y-y of Figure 1.
In the front part b, which is secured to the back part or body a of the chuck, is
arranged a screw furnished with right and left handed threads c and d. This
screw operates two sliding jaws fand f¹ guided in the slot e formed in the part b.
One of these jaws (f) is operated by the left-handed thread d and the other (f¹)
by the right-handed thread c. The jaws ff are held in the slot e by back plates
and screws in the usual way. One of the jaws (f) is furnished with a V-shaped
notch which serves to receive the object to be held, and the other jaw (f¹) with a
corresponding V-shaped projection which serves as a pressure piece to hold the
object in the aforesaid notch. The pitches of the screw threads d and c are
respectively proportioned to each other as 1 is to the sine of half the clamping
angle of the V-shaped notch in the jaw f.
The jaws of the clutch are actuated by means of a key applied to a square g
formed on the end of the right and left handed screw cd, and in
of
consequence
the difference in the pitches of the threads the jaws move in such relation to one
another that they always clamp the object to be held, whatever may be its diameter
with its axis coincident with that of the chuck.
This chuck has the advantage over those heretofore in use that it works easily
and with great accuracy, and is operated by a single screw only.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The new or improved two-jaw chuck in which the two holding jaws, one of
which (f) is formed with a V-shaped notch, and the other (¹) with a V-shaped
projection, are operated by a right and left handed screw the pitches of the
parts dc of which are respectively proportioned to each other as 1 is to the sine
of half the clamping angle of the V-shaped notch in the jaw f, substantially as
described.
