Reproducing Mechanism for Phonographs.
I, MAX SCHLUSS, of 27, Albertstrasse, Gohlis, near Leipzig, Germany,
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:-
-
In phonographs, as hitherto constructed, the pencil or pin for receiving or
repeating the sound waves is cemented or otherwise fixed direct to the diaphragm
of the sound box. The disadvantage of this is that a part of the plane of vibra-
tion of the diaphragm for the production, propagation or transmission of the
sound is rendered useless. According to the present invention, the receiving
or repeating pin is fastened to a spring, which carries upon its free end a ball
arranged to bear against the centre of the metal diaphragm of the sound box, so
that the contact between the two is always at a single point only.
Referring to the accompanying drawings, Figure I is a section, and Figure 2
an elevation of a sound box of this description.
The metal diaphragm m is inserted in the sound box. In order that the sound
may not be objectionably affected by the vibrations peculiar to the metal itself
layers of india-rubber may be inserted between the diaphragm and the case.
The receiving or repeating pin d which bears against the phonograph cylinder w
is fastened to the spring f, which extends beyond the middle of the diaphragm m
and carries on its free end, a ball g which rests or bears against the centre of the
diaphragm mi In consequence of this spherical shape the contact surface
between the spring and the diaphragm is reduced to a single point. If this be
the central point of the diaphragm the whole surface thereof will be free for
the vibrating transmission of the sounds. In this manner, the latter will be
very clearly repeated.
A connection of this kind between the receiving and repeating pin and the
metal diaphragm is considerably more sensitive than the direct fastening of the
pin to the membrane by cementing or the like.
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 sounding box for phonographs, the distinguishing feature of which is that
the receiving or repeating pin is fastened to a spring f which carries upon its
free end a ball arranged to bear against a metal diaphragm m, for the purpose
of enabling the whole plane of vibration of the membrane to be utilised for the
production or transmission of sound.

Appliance for Cycles for Surmounting Inclines and for Use on Snow
and Heavy Ground.
I, LUDWIG MEYER, of 24, Heinrich Strasse, Hanover, in the Empire of Germany,
Merchant, 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 appliance, which, attached to
cycles will facilitate the mounting of inclines, and render the use of the cycle
practicable in the case of snow.
In the annexed drawings, the appliance is represented in Figure 1, as attached
to a wheel, and in Figure 2 as seen from above.
The appliance for facilitating the mounting of inclines is attached to the back
wheel or to the front wheel; or, in case the cycle is to be used for riding in snow,
to both wheels.
The appliance consists of a broad leather belt a, which is adapted to be fastened
on the inner rim ly means of small straps c, arranged at the sides, and provided
with a fastening device b. The use of the cycle in the snow, in the case of heavy
ground, and on steep inclines, is partly impossible, partly a matter of great diffi-
culty. The reason for this lies in the fact that the customary rubber tyre touches
the ground only on a very narrow line. Now the effect of the present invention
is to widen this line of tread to such an extent, so that the surmounting of diffi-
cult ground is facilitated, and the wheel is given a larger "gripping" or contact
surface in the case of heavy roads, and snow.
b
The fastening appliance 6 may be of the well known glove fastener type, which
being of a spring" nature in themselves, are pressed on to buttons d'arranged
on the rim at suitable intervals. Other suitable known types of fasteners may
however be used, in lieu of the above specific type.
In any case, the principal thing to be considered is that the fastener shall hold
the belt a close to the tyre of the wheel.
The appliance is easily rolled up, and carried without difficulty when not in
use.
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:
―
1. The herein described appliance for use in connection with cycles, consisting
of a broad leather belt a with straps c for fastening it to the inner rim of the

page_text: wheel, and fasteners whereby the mounting of inclines is facilitated, and
also the use of cycles in snow, or on heavy ground is rendered practicable: sub-
stantially as set forth.

Improved Method of Rendering Iron Vessels Resistent to Acids.
A communication from the SOCIÉTÉ ANONYME DE PRODUITS CHIMIQUES DE
DROOGENBOSCH, of Ruysbroeck, Belgium.
I, ALFRED JULIUS BOULT, of 111, Hatton Garden, in the County of London,
Chartered Patent Agent, 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:―
When concentrated sulphuric acid is poured over iron particles gas will be
evolved in large quantities. The generation of gas ceases after a few minutes,
but when the re-action is allowed to continue for several days in a closed chamber
at a temperature of about 35° C. accompanied by constant agitation it will be
observed that a generation of gas continues even if chemically pure acid is used
for the purpose. Hydrogen and sulphurous acid are evolved while the iron passes
into solution partly as oxide and partly as protoxide.
The re-action of concentrated sulphuric acid on iron particles is totally different
however if the latter are subject before being treated with the acid, to a
temperature of about 800° C. while air is freely admitted. Iron thus prepared
does not evolve any gas on being treated with sulphuric acid, neither immediately
or subsequently, less iron enters into the solution and the solution contains only
oxide of the metal.
By thus heating the iron a coating of more or less oxidized iron forms on the
metal which is not soluble in concentrated sulphuric acid, and thus protects the
iron under the oxide coating against the attack of the acid. The same remarks
apply to nitric acid and other acids.
According to this invention, therefore, the iron parts employed in the construc-
tion of acid-holding vessels, such as are to be used for storage or transport
purposes, are heated before they are made up or connected together, up to
incandescence and until the protecting iron oxide coating is formed; or the
completed vessels may be treated in a similar manner by heating them under
a current of air or oxygen.
Having now particularly described and ascertained the nature of the said
invention, as communicated to me by my foreign correspondents, and in what
manner the same is to be performed, I declare that what I claim is;-
A method of increasing the resistance of iron vessels or plates against the
attack of acids and for avoiding the generation of gas in closed iron vessels
intended for the storage or transport of acids consisting in heating the said
vessels or parts employed in the construction of such vessels to incandescence, air
or oxygen being admitted during such heating, substantially as described.

parallelogram has this inscription but on the drawing the central one only is shown
with the inscription in order that the drawing may be clearer.
The rectangular sheet thus divided is cut along the lines mn, op, grand st;
it is then folded in the same way as the sheet in Fig. 2 so that the five parallelo-
grams, bearing the inscription, appear visible; the sheet forms in this manner
a cover of parallelopipedon form which is placed so as to fit on and cover over the
similar receptacle containing the fire-lighters.

FREDERIC GEORGE SISON НAM, of 13, Grosvenor Road, Westminster, S.W.,
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 has for its objects to provide a means of distributing the weight of
the cover in the frame over two or more bearing surfaces instead of the whole
weight of the cover resting upon one ledge or seating only as is usually done.
also to maintain a permanent equal level between the top of the cover, frame, and
road surface.
A further object of my invention is to prevent grit or other foreign substance
collecting between cover and frame thereby rendering the removal of the cover a
difficult operation..
According to my invention I provide a frame having two or more steps,
ledges or seating into which I fit the cover similarly provided with two or more
steps ledges or seatings to correspond with and rest upon the steps, ledges or seat-
ings which form part of the frame. I thus provide a much larger bearing surface.
The uppermost ledges of the cover and the frame are always in contact but the
lower ledge or ledges may be free until the cover has worn down to its seatings.
The cover may be constructed in such a manner that when new and first fitted into
its frame its top surface is slightly above the level of the top of the frame so that
after a certain amount of use the cover is worn down until its lower ledge or
ledges are brought into contact with the lower ledge or ledges of the frame and
the top of the cover is on a level with the top of the frame and the road surface.

Improvements in Fasteners for Neckties.
I, Dr. HANS ZIEGLER, Professor, residing at Reutlingen, Kingdom of Würtem-
berg, 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: —
My invention relates to a fastener for neck-ties in combination with a collar
stud.
Various neck-tie-holders are made and sold, but they are useless because some of
them are provided with a pointed catch which pricks holes through and spoils
the neck-tie, and others without a catch allow the neck-tie to slip unless it is pressed
into them very tight. These disadvantages are removed by my invention of which
the following specification contains the objects.
In the accompanying drawing
Fig. 1 is a view of the fastener, closed and with spiral springs.
Fig. 2 is a section through Fig. 1;
Fig. 3 is a view of the fastener closed and provided with flat springs, the
dotted lines showing the lid open.
Fig. 4 is a front-view of Fig. 3.
Fig. 5 is the inside view of the lid.
Fig. 6 is a view from above with the lid removed.
Fig. 7 shows how the fastener is used.
For fastening the apparatus to the collar for instance a double winged folding-
foot (a) is used. To this a U-shaped frame (u) is attached which at the end of its
bent up ends is provided with a hinge (b) at one side and with a projection (c) at
the other, both of which are serving to fix the lid (o) in the known manner.
Inside the upright sides narrow guides (f) are arranged for the purpose of guiding
and fixing the moving of a plate (m). The surface of the plate (m) is riffled,
its sides (n) are bent upwards so that the lid (o), which is also riffled inside, can
place itself between these side-walls (n) Fig. 2.
These bent up walls (n) of the plate (m) which laterally confine the lid (o),
secure a firm hold of the tie and at the same time improve its appearance as they
cause the tie to fall in folds which is not the reason of nor case with any of the
existing fasteners.
The movable plate (m) can be moved up and down in the frame-like guides (f)
of the side-walls.
This plate (m) is always pressed upwards by the springs (r), so that it catches
with its ends under the upper parts of the guides (f), and is pressed down when
the neck-tie is put in and pressed down by the lid (o).
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:-
:―
In a fastener for neck-ties the combination of a movable plate (m), riffled on its

page_text: inner surface and provided with lateral bent up walls (n, n), guides (f) at the
inside of the U-shaped bent lower part (u), springs (s) and folding-stud (a) below
the lower part (u), the bent lower part (u) closed by means of a riffled lid (0)
fixed by means of a hinge.

An Improved Process for Dyeing or Printing on Leather.
We, EDOUARD PELTZER, PAUL PELTZER, and GEORGES PELTZER, trading as
Peltzer & Co., of Renoupré-Verviers, Belgium, Dyers and Tanners, 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 state-
ment:-
This invention relates to an improved process for dyeing or printing on leather,
and consists in reproducing on such material diversified drawings or representations
of all kinds in one color or in different colors at one operation by the following
means.
In carrying out the invention, the drawing to be reproduced on the leather is
firstly prepared on paper or on any other suitable substance by being printed
thereon in one color or in different colors soluble by water, and the desired repro-
duction thereof on the leather is effected by wetting the leather and by stretching
out the original drawing, prepared as above, on and applying it to the wet leather
and maintaining the former in contact with the latter under pressure for a suffi-
cient time for the wet leather to take the desired impression from the soluble color
drawing.
This improved process effects an important economy of time and of labor, and,
at the same time, attains a result superior to anything attainable by the best
process in present use, in which latter the least defect spoils the result and adds
very considerably to the cost of production.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
The hereinbefore described improved process for dyeing or printing on leather
drawings or representations of all kinds in color or in colors, the same consisting
in preparing the drawing or representation to be reproduced on the leather on any
suitable substance in a color or in colors soluble by water and in wetting the leather
and applying the prepared color drawing to the wet leather and maintaining the
same in contact under pressure for a sufficient time for the leather to take the
impression, as set forth.

A New or Improved Insertion Slot Device for Hand Pull Testing.
1, JOHN THOMAS MEDLICOTT BURGESS, of Saint Vincent Street, in the City of
Birmingham, Coal Merchant, do hereby declare the nature of this invention
to be as follows:-
This invention relates to a new or improved insertion slot device for hand pull
testing, and consists as follows;-
A tubular body is formed having at the one end a handlelike formation by which
it may be held in the one hand. Within this tube is a longitudinal spring
pull rod having at its inner end a block or head, between which and the handle
end is carried a spring which thus tends to raise the said block in the tube. At
the outer end of the spring pull rod is a ring or the like by which it may be
taken hold of by the other hand or finger for pulling down purposes. Upon this
rod may be index numbers indicating strength of pull or relative position of
interior block. The upper side of this block is preferably further bevilled and
upon such surface rests the inserted coin or other article. In or near the end
of the tube, an insertion slot or opening is made, which, in the case when coins are
used may preferably be made in an inclined direction or otherwise so as to increase
the difficulty of extracting the coin therethrough. At varying distance downwards
in the tube one or more exit slots are made so that as the pull brings the block
epposite to such slots, the coin &c. will readily fall therethrough:
When two or more of such slots are used, I may place a sliding sleeve upon the
exterior of the tube, by which the several slots above the one determined upon
as the particular exit slot shall be covered, to prevent exit until such an one is
reached.
If desired more than one of such tubes may be grouped together with their slot
or slots arranged after the manner indicated.
As before intimated articles other than coins may be used such as tablets of
choclate or other sweetmeats &c. If desired also I may provide perforations along
the tube serving as sight holes, by which the location &c. of the inserted coin &c.
may be seen.

Improvements in Dental Dams.
I, CHARLES CILANNING ALLEN, of 507, Rialto Building, Kansas City, County
of Jackson, Missouri, United States of America, Doctor of Dental Surgery, 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 that class of apparatus or articles of manufacture-such
as rubber and the like-which is used by dentists for the purpose of damming
up the mouth of a patient during the process of dental surgery; and its principal
object is to provide a simple, economical and efficient dental dam, formed of rubber
or similar material, with a light reflecting surface.
In the accompanying drawing, Figure 1 is a plan view of a dental dam con-
structed in accordance with my improvements, and partly in section; and Fig. 2
a transverse sectional view, taken on line 2 of Fig. 1.
In the art to which this invention relates, it is well known that in using
rubber dams the dental surgeon, whenever it is desirable to inspect the mouth
of the patient, must use a mirror which takes up valuable space and prevents him
from operating efficiently at the same time. This invention, therefore, is intended
primarily to remove the above objection and provide a dental dam, flexible and
elastic in its nature with one light-reflecting surface, as will more fully herein-
after appear.
In constructing a dam in accordance with my improvements, I provide a sheet
of rubber or similar material A, with a coating of aluminium-bronze, or similar
material, B, which does not in any way impair the efficiency of the rubber or
act as a deteriorating agent. This coating of the sheet enables the dentist to use
the dam and take advantage of its flexibility and elasticity, and at the same time
furnishes the mouth of the patient with the maximum amount of light reflected
and deflected by the light-reflecting silvery surface.
Although I prefer to use aluminium-bronze, it will be understood that other
substances for coating may be used which will accomplish to a more or less extent
the objects of the invention; and of course the coated dam may be used either
with or without a mirror, as desired.
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. As a new article of manufacture, a dental dam formed of flexible elastic

COMIDELE DIEUITIVATION.
An Improved Steam Boiler.
We, CARL HÄGER, Mechanical Engineer, and JOHAN VICTOR SVENSON,
Director, both of Kungsgatan 44, Stockholm, Sweden, 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 simple and very efficient steam-boiler.
In Figure 1 of the accompanying drawing, one half of the said boiler is shown
in vertical and horizontal section.
Figures 2 and 3 show like sections of modified arrangements, of the said boiler.
a is a boiler or shell surrounded by tubes n which terminate, at the bottom
in the lower portion of the water-space of the boiler, and at the top in the upper
portion of the steam-space of the boiler, and which tubes, at or close to their
bottom ends c only, are arranged so as to permit a very large amount of the heat
from the heating-source placed below, to be absorbed by the water passing
through the said tubes, so that the water is here transformed into bubbles of
steam which rise in the tubes to the steam-space of the boiler and are immediately
replaced by freshly inflowing water, a brisk circulation being thus produced and
a rapid generation of steam accordingly effected.
To enable the tubes to absorb a large amount of heat at the point mentioned,
they are spirally bent at their bottom part, as illustrated in Figures 1 and 2,
or they may be provided with ribs or flanges d, as shown in Figure 3.
Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed, we declare, that what.
we claim is:
-
A steam-boiler comprising a main-boiler or shell provided with external
water- or circulation-tubes communicating with the bottom and top portions of
the said main-boiler or shell, which tubes, at or near their lower ends, are made
into a spiral or coil or are provided with flanges or the like, while their upper
portions are straight or without such spirals or flanges, for the purpose of enabling
the said tubes to absorb, at their lower ends, the greater portion of the heat of a
heating-source placed below, so that the water may be converted into bubbles of
steam at the said lower ends of the tubes and a brisk circulation and speedy
generation of steam may take place in the boiler, substantially as hereinbefore
described.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Laundry Starch.
I, MARIA DOROTHEA PETERSEN (née Christiansen), of Oberjersdal, North
Schleswig, Wife of a Railway Official, do hereby declare the nature of this inven
ion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:
-
Of the ordinary kinds of starch employed for starching and getting up clothes,
linen and textile fabrics generally, rice starch is most usually employed because
it has very great advantages as compared with the other ordinary kinds of starch,
such as maize starch, wheat starch and especially potato starch. This is doubt-
less due to the fineness of the particles of rice starch which with the aid of a
microscope can be readily seen to be the finest of the ordinary starch flours.
But even rice starch has great drawbacks when used for starching clothes &c.
and dark colored materials (dark blue, dark brown, or black &c.) cannot be
starched with the ordinary starches procurable in the market, without becoming
grey and spotted.
Now the present invention has for object to obviate these drawbacks.
This is effected by manufacturing a laundry starch of peculiar composition,
which has very great advantages as compared with the laundry starches hereto-
fore employed.
This improved laundry starch is made by mixing together sago flour (which
is the finest of all starch flours) dextrin and common salt in suitable proportions.
All these materials are well mixed together in the dry state, then the mixture
is first stirred with a little cold water, and finally stirred up with some boiling
water which is poured slowly into it. All boiling of the mixture must however
be avoided. The following proportions of the ingredients have been found
suitable:-
1 part by weight of dextrin.
These proportions may however be varied.
By using laundry starch prepared in the manner above described for starching
linen &c., all greyness and spotted appearance is avoided and the linen acquires
a much more lustrous gloss than could be produced with the laundry starch
hitherto employed.
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 process for the manufacture of a laundry starch, which consists in
mixing together in suitable proportions sago flour, common salt and dextrin in
the dry state, then first stirring the mixture with cold water, and then with
boiling water, substantially as herein before described.

Improvements in Screw Connections for Brass Vases and Knobs.
GEORGE HENRY BLACKHURST, Clerk, 24, Mostyn Road, Edgbaston, do hereby
declare the nature of this invention to be as follows:-
A metallic wire coiled (or wormed) to form a screw for inserting into the neck
of brass vases or knobs instead of the pummels or cast brass neck parts (which
require tapping to receive the screw) & which are usually used for receiving iron
screw.
The wire when coiled is practically a corrugated tube and adapts itself to being
leaded into the neck of vases by having lead or soft solder poured round, the
outside of coil and inside of neck.
I, GEORGE HENRY BLACKHURST, Clerk, 24, Mostyn Road, Edgbaston, 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:—
A metallic wire coiled (or wormed) to form a screw, for inserting into the neck
of brass vases or knobs instead of the pummels or cast brass neck parts (which
require tapping to receive the screw) which are usually used for receiving iron
screw.
The wire when coiled is practically a corrugated tube and adapts itself to being
leaded into the neck of vases by having lead or soft solder poured round the
outside of coil and inside of neck.
In order to more clearly explain this my invention, I have appended hereunto
an illustrative drawing upon which are figures and numbers of reference.
Fig. 1, is a general sectional view of a knob or vase made according to this my
invention.
Fig. 2, is a detail view of the wire (screw) coil ready for being secured in the
neck of the knob.
Figs. 3, 4, and 5, show suggested sections of coil wire which may be used.
, is the vase or knob to which the neck 8, is secured by any of the usual
9, is a wire coil which is spiralized to any required size and pitch, in
means.

page_text: agreement with the screwthread of a similar sized pin. As will be seen the
sectional shape of the wire may be varied, such as round, square, triangular as
shown in Figs. 3, 4 and 5, or otherwise.
The said coil is preferably secured in the neck before the latter is secured to
the knob. It is held centrally in the neck 8, and secured by molten metal
being poured between it and the said neck.
Such molten metal preferably consists of a solder and assisted by a suitable
flux, but for many purposes such a soldering character is not necessary.
By these means the neck is practically solid, but having an immovable screw
thread of a hard and durable character.
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1. In screw connections for vases and knobs, the forming of the internal
screwthread by means of a coil of wire secured within the neck substantially as
set forth and shown.

An Improved Brick Pallet or Carrier.
Year: 1899

page_text: Date of Application, 7th June, 1899-Accepted, 22nd July, 1899
An Improved Brick Pallet or Carrier.
I, HENRY GRIMBLEBY, of Barrow Haven, in the County of Lincoln, 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 follow-
ing statement: -
Brick carriers are for the purpose of lifting blocks or lumps of plastic or other
clay from the shaping machine on to a barrow or drying boards or otherwise.
Ordinary brick carriers or forks have two or more tines necessitating correspond-
ing holes to be formed in the shaped clay to receive the tines for lifting the same.
My invention or improvement consists of a fork or carrier hereinafter described
so constructed as to automatically embrace or grasp the bricks or shaped clay
sufficiently tightly so that it can be carried without injuring the forni of the
bricks or shaped clay thus dispensing with holes in the clay to receive the tines.
I construct my improved pallet or carrier by fixing to the handle A a stock B
having attached two arms C. C, forming levers the whole attached to the side 1)
by hinge. Side D has attached to it by hinges two wings E, E which have a
portion of their outer sides bevilled as shown in end view drawing and on these
bevilled sides I fix long staples to receive and guide the two lever bars C, C.
When applying my improved pallet or carrier to the bricks or shaped clay the
handle A is held at an angle causing the lever bars C, C, to radiate downwards
pressing against the staples and forcing the two wings E E outwards. When
the pallet or carrier is in position the handle is lowered to the horizontal or
nearly so causing the lever bars C, C to radiate upwards and pressing the wings EE
inwards and against the bricks or shaped clay. The length of the levers C, C,
and the bevilled portion of the outer sides of the wings E, E are so formed that
the grasping of the bricks or shaped clay is sufficiently tight to enable it to be
lifted and removed. The weight of the grasped bricks or shaped clay acts on
the levers C, C, so as to automatically keep the wings pressed tight against the
bricks or shaped clay.
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 and arrangement of parts substantially constituting the com-
plete apparatus for a self acting brick pallet or carrier whereby bricks or shaped
clay can be lifted carrier or removed and laid down without any part thereof
projecting below the bottom surface of the bricks or shaped clay and without pene-
trating tines as described above and illustrated by way of explanation in the
accompanying drawing.
