Improvements in Steam Boilers.
I, RICHARD JOHN O'NEILL, a Citizen of the United States of America, residing
at 1004, North Main Street, Bloomington, McLean County, Illinois, U.S.A.,
Mechanic, 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 certain improvements in steam-boilers designed to
strengthen the same and make them more durable under the great strain to which
they are exposed.
The invention is illustrated in the drawings by means of a face view of a
portion of a boiler-casing shown in Figure 1, and by means of two sections, one
of which, Fig. 2, is cut in line 2-2 of Fig. 1, and the other, Fig. 3, is cut in
line 3-3 of Fig. 1a
In the drawings, A represents the wall of the boiler which is subject to the
heat of the fire, and A', the outside wall. The two are spaced apart by means
of ordinary stay-bolts B. The space between these two walls is the steam and
water space and the pressure is from within outward.
My invention consists in forming the wall A with depressions from the out-
side between the stay-bolts, so that it is convex upon the inside between said
bolts.
The effect of this is that the pressure from within tends to condense the wall
instead of to stretch it, as in the case of an ordinary flat wall. Furthermore,
by making the portions between the stay-bolts convex inward the pressure tends
to crowd the metal of the wall more tightly against the stay-bolts, instead of
drawing it away therefrom and to pinch the bolts more tightly the greater the
pressure. This prevents not only the loosening of the stay-bolts, but also the
bulging of the wall, A, and greatly reduces the possibility of bursting.
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. In a steam-boiler the combination with the boiler-walls and a series of
stay-bolts secured thereto in perforations therein, of a series of depressions from
without inward formed in the boiler-wall between the stay-bolts; substantially
as described.

page_text: 2. In a boiler the combination with a series of stay-bolts, of a wall secured
thereby having the portions between the bolts convex inward whereby the pressure
from within outward tends to condense the metal and crowd the same against
the stay-bolts; substantially as described.

Improvements in Piston Rings.
We SALOMON SIGMUND KRAUSZ, of Bálváryutcza 15 Budapest V, and
SIGILISMOND MÁRTON, of Debreczen, both in the Kingdom of Hungary, Engineers,
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 purpose of this improvement in piston rings is to facilitate the penetration of
the lubricating material between the friction surfaces a.
This purpose is ob-
tained by bevelling the edges of the piston ring so that the surfaces limiting
the surface of friction of the ring sliding along the cylinder wall do not form
a right but an obtuse angle with the sliding surface. Hitherto the section of the
piston rings was a rectangular quadrangle; in this application it is a figure
which could be placed within a quadrangle so that those edges of the rectangular,
quadrangle which come into contact with the cylinder wall, are cut off either
with a conical surface b or with other curved surface, the friction surface of
ring c is thus divided so that the sliding surfaces round the whole circumference
of the ring are limited by the channel d.
The lines of demarcation of the section of this channel pass at one end into the
line of the cylinder and at the other end the guiding lines of those conical or
other surfaces which form a blunt angle with the sliding surfaces. The purpose
of the ring channel c is to divide the sliding surface and to create at the divided
surface a suitable space d for receiving lubricant, for the purpose of guiding the
steam penetrating through a into the space d where its pressure is reduced by the
enlarged space and the oil-water-mixture and it can no longer pass the next
sliding surface a.
This not only economises the ring and cylinder but saves leakage of steam and
therefore fuel, whilst by the form of the ring a considerable saving of oiling
material is obtained.
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:
Improvements in piston rings for obtaining a better lubrication wherein the
sliding surfaces of the piston ring e formed of one piece are divided by suitable
ring grooves d for receiving oiling material into two or more parts a so that the
sliding surfaces a of the ring c and the conical or other surfaces b limiting the same
form together an obtuse angle.

rubber, Gum Elastic, and similar Materials.
I, ALBERT EDVARD JENS VALDEMAR JOHAN THEILGAARD, of 30, Wiedeweltsgade,
Copenhagen, in the Kingdom of Denmark, Chemist, do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement:--
The object of the present invention is a process of disvulcanizing caoutchouc,
india rubber, gum elastic and similar materials, and consists in subjecting the
vulcanized material to a treatment with such solutions that are able to remove
sulphur and especially the alkaline earths.
The following is an example of the above-mentioned process:-
Vulcanized caoutchouc, divided into pieces of a suitable size, is placed in a
recipient adapted for the purpose and is therein treated with a solution of lime or
another alkaline earth in proportion to the amount of sulphur contained in the
material subjected to the treatment.
In order to accelerate the process the temperature may be raised by means of
direct or indirect steam.
When the disvulcanization is finished the solution is removed and the material
is washed and carefully dried. The disvulcanized caoutchouc can now be formed
into new articles and again be vulcanized.
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 process of disvulcanizing caoutchouc, india-rubber, gum elastic, and
similar materials, characterized by the said materials, after being divided inte
pieces of suitable size, are placed in a recipient and treated with a solution of one
5 of, the alkaline earths, eventually under a raised temperature, whereupon the
materials, after a thorough disvulcanizing, are removed from the solution, washed
and dried.

Roller-bearing.
WILHELM SEVERIN, Engineer, 15, Maximfeldt Road, Erith, Kent, 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 article to be patented is a new roller bearing applicable to bicycles, motor
cars and other similar vehicles. It has advantages over existing bearings by its
simple construction causing less friction therefore easy running and can be used as
shewn in Figs. 1 & 4.
Fig. 1 shews a longitudinal section.

"
2 is a side view with dust cap removed.
3 is the detail of rollers.
4 is a longitudinal section shewing two rows of rollers.
5 is a side view with dust cap removed shewing two rows of rollers.
The new roller bearing as shewn in Figs. 1 & 4 consists of an axle (a) and
the hub (6) between which the rollers (c) are arranged. The axle (a) is enclosed
by a holding device (d) for the rollers consisting of a tube like body. The flanges
of this body are fitted with studs (f) for the rollers (e) which run in a direction
inclined to the vertical axle of the hub () in order to be able to regulate for
any slight wear on the bearing. The rollers (c) which are represented in
Figs. 1 & 4 roll on one side of its periphery on a bearing ring (n) of the hub (b)
and on their opposite side upon a cone (2) mounted upon the axle (a) and
formed at the same time like a nut which is held in its position by a lock nut (k).
By exact work the friction of the new bearing should only exist in the two points
that is in the ring (n) and on the cone (i) so that the friction is reduced to a
minimum. The studs (f) are held in a rigid position by means of a ring (1)
so as to prevent the rollers from touching one another. The rollers (c) are only
hardened at the periphery and the hole in the centre of the roller (c) is counter-
sunk on both sides so as to have free play on the studs (f) & to allow for same
taking their inclined positions. The roller bearing as shewn in Figs. 4 & 5
shews a second method of constructing same with two rows of rollers. The
bearing (m) in Fig. 4 is arranged for two rows of rollers also the cone (i) in
Fig. 4 is arranged for two rows of rollers.
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:
The combination using the rollers guide with studs and the rollers.

The bottom A the sides B, and end Care constructed in the usual way.
In the bottom A near the end C we form one two or more apertures or slots I)
to allow of the escape or drainage of water. The apertures or slots D are made
narrow on the type side to prevent the type falling or passing through and wide
at the back to allow of ample clearance so that the hole cannot be readily clogged
or choked with dirt.
The hole or aperture I) is formed in Figs. 1 to 3 by cutting one or more large
slots or holes in or through the bottom A. These holes are placed so that they
are principally covered by the end C thus presenting a narrow slit at the inside
of the galley and a wide opening at the back or underneath. Instead of being
cut square through the bottom plate the holes 1) may be inclined towards the
front thus forming the slit.
A hole or slot with small inlet and large outlet may also be formed in the
end C or near the corner of the side B for the purpose of drainage sufficiently
wide at back to prevent clogging or choking.
In Figs. 4 to 6 the holes or apertures D are formed by cutting away a portion
of the end C inclined from front to back forming a narrow slit at the front and
a wide opening at back. Instead of cutting the end a tapered hole may be
drilled through the end at any convenient position.
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 printers galley constructed with drainage holes at one end formed with a

Improvements in Clippers for Animals' Hoofs.
Year: 1899

page_text: Improvements in Clippers for Animals' Hoofs.
I, EDWARD COURT, 58, Warrangate, Wakefield, Engineer, do hereby declare the
nature of this invention to be as follows:-
This invention consists of a new or improved clipper for clipping the hoofs of
animals. At certain parts of the season, such as the time when they are to be
confined in mistles, there is a superfluous accumulation of hoof which renders
walking painful to the animal and has a tendency to cripple them.
In carrying out my invention I form the clippers of suitable material, such as
steel jaws, of a suitable shape and configuration. The shearing or cutting edges
of these steel jaws being shaped or arranged so as to conform approximately to
the shape or configuration of the part to be operated upon thus enabling the super-
fluous hoof accumulation to be cut away without causing the animal pain or
inconvenience. The cutting blades or jaws one of which is serrated are carried
upon suitable handles or supports and a set screw or pin may be employed for
the purpose of regulating the amount of play or cut of the jaws.
EDWARD COURT, Engineer, 58, Warringate, Wakefield, 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 of improvements in clippers for animals hoofs, and the
essential feature is the toothing or roughening of one of what may be termed the
clippers.
For purposes of illustration, I will refer to the annexed drawings in which: -
Figure 1, is a de elevation shewing my invention.
a is a lever or handle pivoted at b to the lever or handle c which carries the
cutting edge d. The lever a is provided with the toothed or corrugated surface c
for the purpose of preventing what is called slipping when cutting the hoofs of
animals as owing to the corrugated or toothed surface or edge e a greater grip
is obtained than would be possible in the case of two cutting edges being employed
without the corrugations or toothing as shewn at e.
The toothed or corrugated surface may be bevelled in the required direction
.

page_text: and the cutting edge may be what is termed hollow ground in order to prevent
"choking" or catching of the clippings.
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. The improved clipper for animals hoofs, substantially as described and illus
trated herein and for the purpose set forth.
2. In clippers for animals hoofs, the employment of a toothed or serrated edge
or surface in combination with a cutting edge, substantially as described and
illustrated herein and for the purpose set forth.
3. A clipper for animals hoofs consisting of two rods or levers pivotally con-
nected together, one rod or lever having a toothed or serrated edge of the required
configuration, and the other rod or lever having a cutting edge, said cutting edge
and serrated or toothed surface being adapted to prevent slipping of the desired
object when being cut or clipped.

A New Knitted or Woven Fabric for Underwear,
I. CARL ENGELBERT STURM, of Kleinbeerenstrasse 26, Berlin, in the Empire
of Germany, Doctor of Medicine, do hereby declare the nature of this invention
to be as follows;
The present invention relates to stuffs woven or knitted of nettle yarn for wear
directly against the skin.
Instead of using pure nettle yarn (ramie, Chinagrass, Indian nettle and the
like) one can also mix them with any other textile fibre in large or small pro-
portion for making the stuff.
Out of these materials are made underclothes as for instance under shirts, pan-
taloons, stockings and the like which are worn directly on the skin and come
intimately in contact with the body. Such improved garments are very agree-
able in wear in consequence of the hygroscopic qualities of the nettle fibre and do
not irritate the skin as for instance wool does.
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:
A fabric produced by knitting or weaving nettle threads or nettle threads
mixed with any other textile fibre thread for garments or the like worn directly
against the skin.

Process for Combining Ornamental Representations in Relief
with a Suitable Ground-work or Back-ground.
I, JULIUS WEZEL, of 17, Dresdnerstrasse, Leipzig, in the Empire of Germany,
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:
This invention relates to a process by means of which representations in relief
impressed on textile materials, paper, leather, celluloid, sheet metal or other
impressionable substances, and employed for the ornamentation of all kinds of
objects, can be applied to a ground work, in a manner essentially different to that
employed hitherto.
According to the usual method, the representations in relief are stamped,
cut out and then employed for ornamenting all kinds of objects such as glove
boxes, screens, bon-bons etc.
According to this invention the ornamentations, no-matter of what material
they may be made, paper, leather, celluloid, metal or otherwise, are after having
been duly sketched fastened to the ground work, by gumming, riveting, or in
the manner that is most suitable.
After being fastened together, the two connected parts are completed by stamp-
ing out, whereby the representation fastened evenly on to the ground work,
not only appears in relief but also so closely connected with the material as
to suggest their having been produced in one piece.
S
By the means adopted, the part in relief is made more durable and shows
up better and clearer.
It is thus worth while to print better class productions on a better kind of
ground, for example, good silk, as they can be worked on an underground of
less valuable material, and so that the work is not visible.
A textile material may be combined with a similar material, leather with
leather, a textile material with paper, paper with paper, metal with metal, and
so on through all the possible variations, and be thus applied in the most varied
ways.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what
I claim is:-
Process for combining representations in relief, impressed on textile material,
paper, leather, celluloid, sheet metal, or other impressionable substances, and cut
out into objects for ornamentation, with a suitable ground-work or back-ground,
by first cutting the picture that is to give the relief, then joining it evenly with
the flat back ground by gumming, riveting or otherwise, and in this condition

page_text: stamping out or embossing it in conjunction with the said ground, in order to
impart to the relief the appearance of being in one piece with such ground as
well as to give it greater durability and clearness.

Method of Producing Hard Mantles or Hoods for Incandescent Light.
We, OTTO HENTZE, of 5, Koenigsplatz, and HERMANN MÜLLER, of 3, Markt, both
Merchants, at Leipzig, in the Kingdom of Saxony, and German Empire, 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: -
Our invention relates to a new and improved method of producing mantles or
hoods for incandescent light and the object of our invention is to obtain hard
mantles or hoods for incandescent light, which are insensible against rough
handling and careless shocks.
The mantles or hoods for incandescent light, at present in use, are made of a
tissue impregnated with a solution of nitrate of thorium and a solution of nitrate
of cerium or the like and are sensitive to such an extent, as to fall to pieces like
a cobweb at the slightest touch or shake.
After many laborious experiments we succeeded in discovering a process of manu-
facture, by means of which such resistance and hardness can be imparted to said.
mantles, or hoods, as make them insensible against rough handling and careless
shocks, not only without reducing their candle power, but by actually increasing
it, as clearly shown by experiments.
:
Our above mentioned process consists in impregnating the mantles or hoods
for incandescent light made of a tissue of cotton, wool or silk, with the nitrates
of thorium and cerium or the like, with the addition of Carlsbad-salts and Carlsbad-
mineral spring-water of any one or all the different sources of Carlsbad, or their
ingredients.
The process is simple and inexpensive and the results obtained will allow of
a hitherto impossible extension of the incandescent gaslight for all purpose,
especially for street- and railway-lighting.
It is obvious that this invention will open a new field to the incandescent light
industry and that the resistible mantles or hoods prepared by our new and
improved process will soon entirely supplant the old fragile and brittle products.
Having now particularly described the nature of our said invention and in what
manner the same is to be performed, we declare that what we claim is:-
1. A mantle or hood for incandescent light made of a tissue of cotton, wool, silk,
or the like, impregnated with Carlsbad salts or Carlsbad waters of any one or all
the different sources of Carlsbad or their ingredients.
2. The production of incandescent light mantles or hoods, made of a tissue of
cotton, wool, silk or the like, impregnated with the nitrates of thorium and cerium
and the like, with the addition of Carlsbad salts and Carlsbad waters of any one
or all the different sources of Carlsbad, or their ingredients.

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:-
Spanners employed at the present time with a jaw adaptable to different sizes
of nuts or bolt heads are mostly constructed in such a manner that grip pieces are
inserted into the bush of the head and retained therein by screwing. In spanners
of this kind the shape has on the one hand to be modified, and further the
operation of inserting and removing the said grip pieces involves great loss of
time.
The object of the present invention is to produce a spanner of the simplest
form, the jaw of which is rendered serviceable by the simple insertion or removal
of special grip pieces adapted to engage different sizes of nuts or bolt heads. The
inserted grip pieces are either made flush with the surface of the jaw or are made
to project over the jaw upon both sides, so that the spanner can also be applied
to nuts located close together.
Such constructional form is represented in the accompanying drawing, in which,
Fig. 1 is a front elevation, Fig. 2 is a longitudinal section on line B-B
Figure 1, and
Fig. 3 is a transverse section on line A, A, of Fig. 1.
The grip pieces or insertions a are so shaped that their outer dimensions exactly
correspond with the inner dimensions of the spanner jaw, the span of which
varies according to the different sizes of nuts and bolt heads. Internally, the
grip piece a is strengthened by a web or rib d so that breakage of its jaws is
rendered practically impossible. The fixing of the grip pieces or insertions a
may be effected in any suitable manner, in the drawings the grip piece is repre-
sented as formed with exterior grooves which fit the spanner jaws, and when
slipped into position is firmly fixed by means of the extension † formed on the
web said extension fitting within a recess in the spanner handle and being
secured therein by the screw e. The said grip piece a projecting over the jaw cat
both sides and having its ribs 6 firmly applied against the side faces of the jaw.
the grip piece is prevented from wearing angular.
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 spanner with adjustable span, the characteristic feature being that the grip

page_text: pieces or insertions introduced into the jaw, either project upon both sides over
the jaw or are made flush therewith and that the strength of the grip piece or
insertion is increased by a rib connecting its jaw substantially as described.

Improvements in Apparatus for Generating Acetylene Gas.
I, Dr. LEON STEINER, of Technisches Bureau fur Acetylenbeleuchtung, 2, Strada
Academier, Bucharest, Roumania, 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 this invention is to provide an acetylene gas generator, in which
the generated gas is thoroughly cooled and, at the same time, owing to the
arrangement of the generator, whereby the cooling is effected, the possibility of
explosion, in the case of excessive production of gas is entirely prevented.
The accompanying drawing illustrates one form of acetylene gas generator
constructed according to this invention.
The carbide receptacle a is supported in the gas holder b, and can be taken
cut from the side or from below. The gas holder is surrounded by a water
tank the two being connected by means of holes m or the like, so that the lower
part of the gas holder contains water. Above the water level in the tank c one
extremity of a safety pipe d projects, the other being carried outside into the
open air.
The two vessels bc serve for cooling the gas and the carbide and, owing
to the arrangement of the safety pipe render an explosion, in case of excessive
production of gas, impossible.
Above the vessels bc is a water reservoir e, to which the water necessary for
generating the gas is conveyed through the opening . By means of the
valve which can be rotated from outside through the medium of the valve
rody, the admission of water to the carbide on to which it drops through the pipe i
is regulated. Pipes f convey the generated gas from the generator a to the gas
holder b, the gas being cooled in its passage. Thence it is conveyed by pipes to
the place where it is to be consumed.
If too much gas be generated, the pressure of the gas forces the water out of
the holder b into the tank c whence it can escape through the safety pipe d, so
that an explosion in case of excessive production of gas is rendered impossible.
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. An acetylene gas generator, the distinguishing feature of which is that
the carbide receptacle a is arranged in the gas holder b, the lower part of which
contains water, the holder b being surrounded by a water tank c, and connected
therewith by means of openings m, a safety pipe d extending above the water level
being provided in the water tank, so, that, in the case of excessive production
of gas, the water is forced by the pressure of the gas, out of the gas holder into
the water tank, which surrounds it, and can escape through the safety pipe.

We, THOMAS MORTON, of Saint Georges Place, in the City of Birmingham, and
GEORGE TAYLOR, of 4 and 5, Long Lane, Aldersgate Street, London, E.C., Manu-
facturers, 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;-
;一
This invention relates to improvements in means for securing elastic or other
similar bands to dress clips, and is primarily intended for double-ended elastic
band clips for retaining shirt sleeves and the like, but it will be readily seen
that the same may be applied to similar clips for other purposes.
In order to more clearly explain this our invention we have appended hereunto
an illustrated drawing upon which are figures and numbers of reference, in
which similar numbers refer throughout the several views to the same thing or
part.
Fig. 1, is an enlarged general side view of clips connected to each other by an
elastic band, according to this our invention.
Fig. 2 is an enlarged sectional plan view of the invention on line A-B Fig. 1.
Fig. 3, is a doubly enlarged sectional side view of the invention on line C-D.
Having reference to the drawing:-5, is the body of the clip, having the
interior grip spring 6, which is secured thereto by the gate frame 7, which is
soldered or otherwise secured to the spring and to the body. The grip spring 6, is
operated in the usual manner by the lever 8. To these clips is secured the
band 9, which may be of elastic or other suitable material.
As will be seen the end of the band is placed between the spring G, and the
lower part of the clip body 5, and carried thence below and along the underside
of the said body and upwardly through gate opening 10, and again downwardly
through gate opening 11. In the spring 6, one or more teeth are projectingly
pushed down so as to catch into the band 9, which further tends to prevent its
removal. By these means the band is securely fixed to the clips, and the said band
also furnishes a very desirable fabric covering to the lower part of the clip body.
Having now particularly described and ascertained the nature of this our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. Securing the end of a band to a clip body 5, having an internal part 6, and
gate frame 7, by passing the end through the gate frame, and thence between
the parts 5 and 6, substantially as set forth and shown.
2. Covering the lower part of the clip by means of an extension of the band or
the like fabric, substantially as set forth and shown.
