Improvements in Hard Roller Castings and in the Manufacture
thereof.
I, ERNST MURMANN, of 48, Broichstrasse, München, Gladbach, in the German
Empire, Manager, do hereby declare the nature of this invention and in what man-
ner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
It is well known that chilled roller castings, which are used for crushing material
of all kinds are cast in chills whereby the casting becomes extremely hard on the
outside, while the inner material remained soft, to allow of its being worked.
This manner of casting has many disadvantages, of which the most serious is that
the slightest mistake in casting produces a number of defective articles and that
the chills are often broken. In consequence the cost of production is much in-
creased.
This invention is designed to remedy these effects, by casting a whole roller of
a mixture of iron and steel, which yields a product sufficiently hard and tenacious
to render the roller suitable for crushing mills to disintegrate stones and ores.
The interior of the roller is rendered suitable for working, i.e. for boring it for
bearings, axles, etc., by casting or welding into the hard metal of the roller a
wrought iron ring or equivalent device. The roller is cast in sand or loam in the
usual manner. When the wrought iron rings have been prepared in suitable
manner, and tinned if desired, they are placed on a core, and cast into the roller.
After casting, the whole roller is placed on a suitable lathe and the interior of the
rings are turned accurately.
The material used for casting the rollers consists essentially of hard white iron,
to which is added a certain quantity of steel and wrought iron as may be desirable.
The subject matter of the invention is illustrated in the accompanying drawing.
1 is the roller cast of hard material, and 2 indicates the wrought iron rings cast
into it. The dimensions of these rings may vary according to circumstances. The
rings are preferably turned with a dove-tail on their outer circumference and
tinned in order to ensure a better connection with the casting.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is:-
Hard cast rollers and the method of making the same, in which the roller is
cast entirely of hard material in which are secured by casting or welding wrought
iron rings or similar devices to allow of the adaptation of the hard cast rollers for
any desired purpose, so as to do away with chilled castings and to produce rollers
of great hardness which can be easily worked upon the inside.

Improvement in the Manufacture of Portland Cement.
I, JASPER WETTER, Patent Agent, of 37 & 39, Essex Street, Strand, in the
County of London, do hereby declare the nature of this invention, a communica-
tion from The Firm of Güldenstein & Co., of 125, Mainzerlandstrasse, Frankfort
on the Main, Germany, and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
Hitherto Portland cement has been made principally from alumina and lime.
It is known that blast furnace slag obtained as a bye product in the manufacture
of pig iron, resembles alumina as regards its chemical composition and its hydraulic
properties, for which reason blast furnace slag has been successfully employed for
the manufacture of Roman and Puzzolana cement.
The present invention has for its object, to utilize blast furnace slag for the
manufacture of Portland cement..
For this purpose I introduce the slag directly from the blast furnace, and in
an almost liquid condition, into cold water, whereby it is converted into small
granules, known as granulated slag sand.
This granulated slag sand is dried and subsequently reduced to a powder as fine
as flour by means of suitable machinery, and with the addition of crude lime stone.
The quantity of lime stone to be added depends on the chemical composition of
the slag sand.
As a rule equal quantities of slag sand and of lime stone are employed, only in
rare cases a variation of a few per cent. is necessary.
To the ground product obtained as described pulverized white lime is added
in small quantities, from 4 to 5 per cent. being sufficient in most cases.
This mixture is slightly moistened and moulded in a brick press, so as to form
bricks which are immediately exposed to the open air and after a few days are
delivered to the kiln. There these crude cement stones or bricks are burnt, until
they shrink and harden or sinter after which they are ground to the consistency
of flour.
The Portland cement thus obtained can be used immediately and is of excellent
quality.
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:-
1. The manufacture of Portland cement, which consists in reducing approxi-
mately equal quantities of slag sand and crude lime stone to powder, with the

Improvements in Waterproofing Garments.
I, HERMANN KRAUTWURM, of Pinneberg, in the Empire of Germany, Manu-
facturer, 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 the present invention is an improvement in waterproofing
garments, so that the latter differ in external appearance in no way from garments
of ordinary kind and on the other hand are either partly or wholly perfect.y
water-proof. By way of illustration I have represented in the accompanying
drawings a coat made according to the present invention.
For the purpose of waterproofing garments of any kind I insert between the
external cloth or fabrica and the lining b of the garment a layer of water-
proof material especially at those parts or portions of the garment which are
mostly exposed to the rain. These parts are generally the shoulders, the seams
and partly the front of the garment. It may be understood however that it is
within the scope of the invention to provide the entire garment with an internal
laver of waterproof material, which may simultaneously form the lining.
By inserting at the places required the above mentioned layer of water-proof
material, the appearance and shape of the garment will not suffer in the least
and the weight will only be insignificantly increased, this being a great advantage
over waterproof garments of ordinary kind.
It may be advantageous to employ these layers of waterproof material in com-
bination with ordinary, so-called waterproof garments which are made of chemically
prepared cloth or fabric and which generally are not perfectly waterproof.
Having now particularly described and ascertained the nature of my sail
invention and in what manner the same is to be performed, I declare that what
I consider novel and desire to claim is:-
1. In a garment of any kind inserting at those parts most exposed to the
weather a layer of waterproof material between the outer cloth and lining,
substantially as set forth.
2. In a garment of any kind a lining of waterproof material, substantially as
set forth.
8. An improved waterproof garment, substantially as described with reference
to the accompanying drawings.

Improvements in Stench Traps.
I, HEINRICH BRUNNER, of 32, Route de Chène, Geneva, Chemist, do hereby
declare the nature of this 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 invention relates to an improved construction of stench trap including a
straining device, a sludge receptacle and a sealed outlet.
And in order that my invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings showing a longitudinal section of
one form of my invention in which it may be carried out.
In carrying out my invention I form a cylindrical jacket, the upper end of
which I furnish with a removable perforated lid b and the bottom c of which I form
with an outlet c¹.
In the latter I employ a withdrawable hook shaped pipe d, one end of which
communicates with the interior of the jacket a and the other , with the outlet c¹.
Upon the hooked part of the said pipe is employed a removable cup c having a
withdrawable bottom el and a perforated top serving as a strainer.
e
The cup e is made less in diameter than the interior of the jacket a so as to
provide a space a¹ between the same. The strainer fits all round against the
interior of the jacket so that the fluid which flows to the jacket lid cannot
pass direct into the intermediate space a', but must first pass through the
Strainer and the cup e.
From the latter the fluid passes through the holes e³ near the strainer into
the intermediate space a¹ of the jacket a and through the hooked pipe d out
of the jacket.
The course which the fluid is obliged to take, causes the fluid to be first
strained by the strainers and e², whilst smaller impurities settle in the cup e,
as well as in the interior of the jacket a.
The hooked pipe d prevents the fluid leaving the interior of the jacket com-
pletely, and as it will never descend below the level shown by the dotted line,
the fluid outlet will remain sealed and the return of the drain gases thereby
effectually prevented.
"
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I claim is: :-
A stench trap, consisting of a jacket a, having at its top a strainer and in its
bottom a hook shaped pipe, which latter serves as fluid outlet and stench trap and
carries a cup e of less diameter than the interior of the jacket and formed near its
top with perforations for straining and at its top with a strainer which fits
against the interior of the jacket a and the perforations of which cause the fluid
from the strainer to pass first into the cupe and then through the perfora-
tions in the latter, into the interior al of the jacket a, from whence same leaves
through outlet pipe d, all substantially as set forth.

Improvements in or relating to Means for Converting Trousers into
Knickerbockers,
I, AUBUN LOUIS NOVER, at Dulmen Westphalia, in the Empire of Germany,
Tailor, 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 present invention relates to means whereby ordinary length trousers may
be shortened or converted into knickerbockers at will without turning up the
garment in the ordinary manner.
For this purpose a buckled strap or the like is arranged in the lower edge of
the trousers, which can be unbuttoned at the lower end of the longitudinal side
seam.
The invention is illustrated in the accompanying drawing in which:
Figure 1 is a view of the leg of the trousers with the bottom edge partly turned
back,
Figure 2 is a section through the leg of the trousers as worn ordinarily,
Figure 3 is a section through the shortened leg of the trousers.
The bottom edge of the long trouser leg 6 is turned inwardly and sewn at the
lower end, whereby a pocket is formed, in which a strap with holes and buckle
or equivalent is arranged, which strap is only long enough to be conveniently
taken hold of by the hands. When it is desired to shorten the trousers the button f
closing the side seam of the trousers is undone, and the bottom of the trousers
pushed upwards and fastened round the leg a by the strap d, and rebuttoned. Such
a shortened garment is very elegant in appearance, and is not exposed, when
cycling to be injured by coming in contact with the pedals or with the oil and dust
covered chain.

Improved Device for Closing or Holding the Lids of Sterilizing
Vessels.
1, JOHANN WECK, Merchant, of Schlösschen Oeflingen, at Oeflingen, in the
Grand Duchy of Baden, Germany, 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 devices for holding down the lids of sterilizing
vessels in such a manner, that they prevent atmospheric air from entering the
vessel, but allow the escape of vapours generated during the process of sterili-
zation.
As shown by the accompanying drawing, the improved device chiefly com-
prises a hoop 6, the ends of which are bent inward, so as to extend underneath
the flange of the jar or other receptacle; a pair of bent leaf springs f fixed at
one end to the hoop and pressing with the free end upon the lid; and an inverted
hoop fixed at the ends to the hoop b near the base of the same, and extending
downward towards the centre of the lid, so as to serve as an abutment for the
springs f, when the latter are pressed upward by applying the hoop to the jar,
the hoop being caused to slide on to the flange from the side.
The hoop 6 supports the springs f and assists their downward pressure, so as
to hold the lid securely, even if the contents of the jar are heated beyond a
given limit.
Instead of using an additional hoop 6, the principal hoop 6 may be bent so
as to form an abutment for the springs f, and the shape and arrangement of the
said springs may be varied without departing from my invention.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. A device for holding down the lids of sterilizing vessels or for keeping the
same closed, chiefly comprising a hoop adapted to be secured to the mouth of
the said vessels and provided with springs for holding down the lids, the said
hoop being either shaped so as to form an abutment for the springs, or provided
with an additional hoop, substantially as described.
2. The combination of a flanged jar or other sterilizing vessel having a lid
adapted to be pressed against the mouth of the same, with a hoop b, holding
down springs f, and inverted hoop ', substantially as described and shown by
the drawings.

This invention has reference to the carbonizing of precipitated sewage sludge
within retorts, gas producers, or like apparatus, and obtaining therefrom at
temperatures, which may vary from 1000 to 1400 degrees Fahrenheit, residue
products in the form of char or coke of superior quality.
In carrying out the improvements I purchase concentrated sewage from the
sewage works of towns, or the like, and place same in a retort, or like apparatus
and I bring this to a temperature of from 1000 to 1400 degrees Fahrenheit, and
by this means the organic constituents of the precipitated sewage are decomposed
and the char or coke will remain at bottom of retort and be recovered as a
valuable carbonized commercial product. While the gaseous products composed
of illuminating gas, tar, oil, ammonia and the like can be led away and treated
for their recovery in an ordinary manner.
In the case of treating the sewage sludge for the recovery of the carbonized
products in a gas producer, air and steam would be injected to assist combustion,
but no coals or like burning medium would be necessary the carbonization of
the sludge into char or coke taking place at a temperature of between 1000 and
1400 degrees Fahrenheit.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-

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 present invention consists of a process for producing spirits in solid form.
The product of the process, when burnt leaves but a very slight residue in the form
of a thin tissue, which sinks to the bottom of the receptacle.
The process is carried out in the following manner:-
About 45 grammes of caustic soda are mixed with about 600 grammes of water
and to this mixture are added about 400 grammes of mutton fat or tallow. The
mixture is then boiled for a short time after which a lye is added consisting of
After this mixture
about 40 grammes of caustic soda and 300 grammes of water.
has been allowed to boil again some little time about 85 grammes of common salt
and about 50 grammes of scraped stearic acid are added and the whole allowed to
boil for a short time and then to cool.
The solid resulting product gained forms the mass by means of which spirit in
solid form is attained."
One part by weight of this mass is added to from twelve to eighteen parts of
spirit of 80% or more strength, and the whole heated in a receptacle until the whole
mass is completely dissolved. The result is then allowed to cool and consists of
spirit in solid form.
The substance is of such consistency that it may be melted and cast in moulds
in the size of coffee beans or thereabout, thus, after having become hard, forming
a granular product which may be sold in closed receptacles or retailed by
weight.
The substance may also be brought into any convenient form by pouring the
same out and allowing it to cool in the form of a plate and then pressing or
stamping or hammering into shape or shapes.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
1: Process for producing spirits in solid form which leaves but a slight residue
when burnt, which consists in first producing a saponified mass by a mixture
of mutton fat or tallow and stearic acid, melting the same in warm spirits
and allowing to cool, in the manner and for the purpose substantially as described.
2: A process for producing spirits in solid form which consists in first pro-
ducing a saponified mass consisting of mutton fat or tallow and stearic acid as

resultant mass, after cooling, into granular or other form substantially as
described.

Machinist, do hereby declare the nature of this invention to be as follows:-
My patent refers to machines used in agriculture and especially that branch
for hoeing and clearing the ground from weeds.
The principle consists in arranging a system of hoes upon a frame. These,
by a series of cranks or other suitable arrangement, working from a revolving
shaft hoe the ground not by a forward pushing motion, but by a backward
pulling motion so that hoeing by this machine most nearly imitates hoeing as
performed by the field labourer.
The power utilized for its operation may be horse, steam or other power.

Improvements in Cone-locks for Ball Bearings.
I, FREDERICK MYERS, of 220, East 32d Street, New York, in the County and
State of New York, United States of America, Gentleman, 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 cone-locks for ball bearings for use on railway rolling
stock, bicycles or other vehicles, and the objects sought to be accomplished are,
to produce a device of this character which shall be simple in construction, reliable
and efficient in use and which will be easy to operate.
I attain these objects by means of the construction shown in the accompanying
drawing which forms a part of this specification and in which
Figure is an end view of a bicycle hub, showing my invention applied thereto.
Figure 2 is a partial vertical section of the end of the hub.
Figure 3 is a plan view of my cone-lock or disk.
Figure 4 is an end view of a bicycle hub, showing one modification of my
invention and
Figure 5 is a similar view of another modification of the same.
Like numerals of reference designate like parts wherever they occur in the
various views of the drawing.
1 is a bicycle hub of ordinary construction in each end of which is adapted to
be seated, the ball cone or cup 2. 3 is my cone which has a smooth outer surface,
and a central screw-threaded aperture 4 which screws over the exteriorly threaded
spindle 5. Secured to the outer face of the cone 3 is a detent or pawl 6 which
is pivoted upon the pin or stud 7. This pawl is held sufficiently tight against
the face of the cone by the pin 7 to prevent its movement by the ordinary jarring
of the wheel.
8 is my cone-look which consists of a disk of metal having notches 9 extending
entirely around the periphery thereof. This lock or disk is provided with a central
aperture 10 designed to fit the spindle 5. A lip or projection 11 is formed at some
point within the aperture 10 and the spindle 5 is provided with a longitudinal
groove 12 which conforms to the shape of the lip 11, and when the locking disk
is placed upon the spindle 5, it is prevented from revolving or turning thereon,
by said lip and groove. The balls 13 are seated in the bearing in the usual or
any well known way, it being immaterial to my invention what form of ball
bearing may be used. When the cone 3 has been adjusted to the desired position
within the hub, the pawl 6 having been raised out of contact with the locking
disk 8 for such purpose, said pawl is then moved upon its pivot 7 until its toe is
inserted into any one of the notches 9 in the locking disc 8.
It will be understood, of course, that there is a nut 14 upon the end of the
spindle 5 which holds the parts in contact, as is usual.
Instead of the pawl 6 I may use a hinged toe 6* as is shown in Fig. 4, or a sliding
holt as is shown in Fig. 5.
Or the detent may consist of a pin secured to or integral with the outer face of

I, CARL GROMPE, Merchant, of Leinefelde, in the Empire of Germany, 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 for an improved signalling apparatus has for its object to pro-
vide an apparatus for producing audible signals.
The improved signalling apparatus is shown in the accompanying drawing
and consists in the combination of a steel bottle a with safety valve, officially
tested to 250 atmospheres and filled with, at the utmost, 10 to 11 kilogrammes of
carbonic acid; a metal whistle b; a stout iron pipe c which connects the steel
flask with the metal whistle; a stand in which the apparatus thus combined
can be placed on any desired spot and a safety valve v.
The safety valve on the bottle being opened, the carbonic acid flows away
through the iron pipe c into the metal whistle 6 and thereby produces a sound
like that of a loud-sounding steam-whistle.
Any danger of explosion in handling is out of the question.
By means of this apparatus, signals are given at great distances. It is
thoroughly suitable for sailing ships, factories working without steam, remote
country residences, farms, and houses occupied by foresters, and open lines of
railway, for the purpose of whistling at a distance to stop trains endangered by
thick fog or heavy falls of snow, and for all other conceivable objects, including
the signalling of danger to life or property from fire, water, or otherwise, and
thus procuring assistance.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
:-
A signalling apparatus for producing signals by whistling through the medium
of carbonic acid, consisting of a steel flask a, an iron pipe c, and a metal whistle
connected with the same.

Process for the Production of a Homogeneous Horn Substance from
Horn Cuttings, Horn Shavings, Powdered Horn or the like.
I, FREDERICK WILLIAM GOLBY, of 36 Chancery Lane, in the County of Middlesex,
Patent Agent; do hereby declare the nature of this invention and in what manner
the same is to be performed, as communicated to me by Johann Gustav Bierich, of
Menkenhof near Lievenhof, Russia, Country Gentleman, to be particularly described
and ascertained in and by the following statement:-
The object of this invention is a process for the production of a homogeneous horn
substance from powered horn produced from horn cuttings, horn shavings, powdered
horn or the like, the distinguishing feature of which is that the material to be
worked up namely, raw untreated horn or hoof, after being thoroughly cleaned and
reduced to a fine powder is mixed with about 1% of flax oil or 1% of glycerine and
subjected to a temperature of 100° or more Celsius, for about 40 minutes or more, at
a pressure of about 200 or more atmospheres, the air being excluded from the
material.
The four principal factors.; heat, addition, pressure and time vary in the process
according to the quality of the horn substance which it is intended to produce. If
it be desired to produce a hard brittle substance it will be necessary to employ a high
temperature, without the addition of flax oil or glycerine, whilst, if a soft more
elastic substance be required, it will be necessary to add flax oil or glycerine and to
employ a lower temperature but more time.
The horn substance produced by this process can be worked up like natural horn
and consequently can also be applied to the same purposes.
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;
The process for the production of a homogeneous horn substance from horn
enttings, horn-shavings, powdered horn or the like, the distinguishing feature of
which is that the material to be worked up i.e. raw untreated horn or hoof, after being
cleaned thoroughly and powdered is mixed with flax oil or glycerine as is necessary
and subjected to a temperature of about 100° or more Celsius for about 40 minutes
or more at a pressure of about 200 or more atmospheres, the air being excluded from
the material, substantially as described.
