page_text: I, ALFRED TUCKER, of the East London Works, Sunbury-on-Thames, in the County
of Middlesex, 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 ascer-
tained in and by the following statement:-
My invention relates to the construction of a valve for a fluid main in such a
manner that it can be easily worked notwithstanding that the fluid may be under
great pressure, and that the valve casing is compact occupying little space laterally
beyond the main in which it is applied.
For this purpose I construct the valve and its casing as I shall describe referring to
the accompanying drawings.
Fig. 1 is a longitudinal section and
Fig. 2 is a sectional plan shewing by dotted lines the valve partly open;
Fig. 3 is a transverse section on the line 3-3 of Fig. 1 and
Fig. 4 is a transverse section on the line 4-4 of Fig. 1.
The valve a is a cylindrical shell provided at its ends with slightly projecting
rings be which may be of gun metal these rings being slightly tapered, the front
ring a little smaller in diameter than the rear ring c. This valve is made with a
cross rib d having a central boss with an internal screw thread to serve as a nut on a
screw spindle e connected by bevil gear to an upright spindle f which passes up
through a stuffing box and made with a square end or its equivalent to receive a
suitable key. From another cross ribh through the boss of which the screw spindle e
freely passes project two brackets i which can slide freely along grooves ; formed
along the interior of the main pipe k, the valve a being thus prevented from turning
when the screw spindle e is turned. When the valve & is advanced its rings b and c
fit rings slightly projecting from the interior of a cylindrical shell which has
through it numerous openings in the form of slots preferably having their ends
sloped in the direction of the fluid flow. Outside the shell is the casing m of such
internal diameter that the annular area within it around the shell is of the same
area as that of the main pipe ».
From this construction it will be seen that the frictional resistance to the opening
or closing of the valve by the longitudinal movement of a is not in any way affected
by the fluid pressure in the main, and that the only lateral space occupied beyond
the main is that of the casing m and the upper part of the spindle and its stuffing
box g.

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 valve for fluid mains comprising a sliding cylindrical shell which hu manna afa

page_text: screw and suitable gear can be advanced within or retracted from a perforated shell
arranged within a casing communicating freely with the main, substantially as
described.

Improvements in the Construction of Ladders.
I, WILLIAM WHARLDALL, Junior, of Southgate, Pontefract, in the County
of York, Cabinet Maker, 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 ladders and step-ladders, the object being to construct
a ladder or step-ladder which shall be very strong and durable, at the same time
being very light and produced at small cost.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a front elevation of my improved ladder.
Fig. 2 is a side elevation of same.
Fig. 3 is a plan of same (enlarged).
Fig. 4 is a side elevation of my improved step-ladder.
My improved ladder (see Figs. 1, 2, and 3) is made in the following manner:-
Each side of the ladder consists of two parallel wooden rods A, A, between which
are fastened at regular intervals a series of small wooden blocks B.
The said blocks B are hollowed on their vertical edges to receive the rods A A,
and are bored at their centres to receive the ends C of the rungs D. Each block B
may be secured in position by nails, screws, or bolts E E, preferably at top and
bottom of the block (see Fig. 1); this prevents the rungs being weakened as they
would be if the nails, screws, or bolts passed directly through them. The block
which supports the lowest rung is preferably extended to the foot of the ladder.
In constructing my improved step-ladder (see Fig. 4) the steps F are provided
with projecting pins G at each end, the said pins being supported in blocks B
held between rods A A as described above.
The pins G G on the top step are extended outwards so as to form pivots for the
supporting legs H H.
A cross bar K, bearing against the top step F, is provided to limit the outward
movement of the legs H, or chain or other stays may be provided for this purpose.
A short hand rail L is also provided on each side at the top of the step ladder.
My improved ladder and step ladder, being very light and portable, are particu-
larly adapted to domestic use, but are also suitable for warehousemen, builders,
and for indoor or outdoor use generally.
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 the construction of ladders or step-ladders the combination of the
rods A. A and the rung-supporting blocks B, the said blocks B being fixed at
suitable intervals between the rods A A by means of nails, screws, or bolts E
80 as to form the side uprights of the ladder or step ladder, substantially as shown
and described.
2. The complete ladder constructed substantially as described and as illustrated
at Figs. 1, 2, and 3 of the accompanying drawings.

An Improved Method and Means for Refining and Strengthening
Iron and Steel for Casting or Founding purposes.
We, JAMES EVANS, of Britannia Works, Salford, in the County of Lancaster,
Manufacturer, and ROBERT AUSTIN SMITH, of 9, St. Margaret's Terrace, Plum-
stead Common, London, in the County of Kent, Founder, 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:
Our process consists in treating the iron or steel, during any of its processes of
manufacture, from its first melting from pigiron, to its final melting for casting,
either in the form of iron, or after its conversion into steel, with a suitable com-
position or flux consisting of a combination of about equal parts of oxide of lead,
bicarbonate soda, and nitrate of potash, (but a convenient working proportion is
one part of oxide of lead, two parts of bicarbonate of soda, and three parts of
nitrate of potash), either plain, or mixed with a suitable conveyor, such as
bauxseite or even ordinary sand.
The proportion of the composition or flux required, is for ordinary casting iron
about one and a half parts of composition to one hundred and seventy eight parts
of iron, and for steel about three parts of composition to three hundred and fifty
six parts of steel, but it will be easily understood that the proportion is only
approximate and required varying according to the quality of the iron and steel
dealt with.
The flux or composition may be combined with the metal, either by placing
the required quantity at the bottom of the ladle into which the molten
metal is poured for casting purposes, or by blowing it into the cupola of the
melting furnace below the melting zone, or best of all, by blowing it directly
through the molten metal.
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 improved method and means for refining and strengthening iron and steel
for casting or founding purposes, substantially as described herein before.

A. Holder and Cutter Combined for Reels of Cotton or other Thread.
I, DONALD WILLIAM MCLEAN, of Mount Hutt, Methven, Canterbury, in the
Colony of New Zealand, Farmer, 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 a very simple and inexpensive con-
trivance for holding a reel of cotton or other thread in such a manner that the
end of the thread is left overhanging so as to be instantly grasped, but so held
that the reel will not turn until a slight movement is made whereby the thread
is released and the reel enabled to turn, when any required length of thread can
be drawn from the reel and then passed over a cutter formed upon the said
holder thereby cutting off the desired length of thread and at same time
securing the remaining end and leaving sufficient overhanging ready for use
again.
The holder and cutter combined can be made different sizes so as to be used
for varying sizes of reels.
Referring to the accompanying drawings illustrating my invention.
Fig. 1 is a side view of the holder clipping a reel of thread and showing the
end of thread secured but sufficient overhanging to be easily grasped.
Fig. 2 is an end view of same.
Fig. 3 is a side view showing the end of thread released ready for drawing out.
Fig. 4 is a side view showing the thread drawn out and passed over the cutter
at top in position for cutting off. A is the holder which is made of one piece
of wire (preferably steel) turned and formed in the shape as shown.
The two outer ends (") clip the ends of reel B containing the thread, the
tension of these ends preventing the recl from turning too freely.
The end of the thread is passed through the coil (b) thence threaded through
the loop (e) from the inside and then pulled upwards causing it to be jammed
between the side of the loop and the coil as shown in Fige. and 2 leaving the
end available for instant grasping.
When a length of thread is required, the overhanging end is pulled down clear
of the coil (as shown in Fig. 3) and the desired length drawn from the reel,

page_text: when an upward movement is made to draw the thread between the loop and the
coil, and then passed over the cutter (d) as shown in Fig. 4, a slight pressure
only being necessary to sever the thread, the remaining end being still secured
in the coil but sufficient left overhanging to be readily grasped again when
required.
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 hereindescribed holder and cutter combined for reels of cotton or other
thread consisting of one piece of wire, preferably steel, constructed, arranged
and operated substantially as herein described and illustrated in the accompany-
ing drawings.

Improvements in or relating to Switches for Conductors in Electric
Traction Systems.
I, HERMAN OTTO JOEDICKE, Manufacturer, of Friedrichstrasse, 47, Mühlhausen
(Thuringia), 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:--
The present invention relates to the well-known switches for electric railways
or traction system, particularly those in which overhead current collectors are
employed, and comprises two tongues cd, the pivotal points of which are situated
opposite to each other the tongues being automatically operated by the passing
current collecting roller.
When the current collecting roller a runs from one fixed contact a¹ to another a
the tongue e the tension of its spring being overcome, is pressed against the
tongue d and the roller passes, the tongue c resuming its normal position after
the passing of the current collecting roller. When, on the other hand, the current
collecting roller runs from 6 to a¹ the tongue d the tension of its spring being
overcome is pressed outwards in the direction of the arrow and I and returns
after the passing of the current collecting roller to the position shown in Figure 1.
During the passing of the current collecting roller over such switch tongues
the difficulty very easily arises that in consequence of the resistance of the
tongues, acting under the influence of a spring, against the movement of the
current collecting roller x the said roller jumps off the switch tongues, i.e., off
the switch itself.
In order to overcome this drawback guide plates i¹ are provided on each side
of the switch tongues viz. plate i for the switch tongue c and plate ¹ for the
switch tongued these plates having projecting edges turned inwardly. The
projecting edge of each guiding plates holds and catches the studs y or axle pro-
jecting on each side of the current collecting roller a whilst the current collecting
roller is passing over the switch tongues i.e., the air switch.
This switch can also be adapted for use with overhead wire conductors.
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. A switch for electric traction systems with three fixed conductors such
as a, a, b comprising intermediate spring controlled switch tongues such as c
and d with oppositely arranged pivotal points in combination with guide plates
having inwardly turned edges adapted to engage with the axle or studs on
the current collecting roller when the latter passes in order to prevent the jumping

page_text: off of the roller from the tongues at the switching points substantially as
described.
2. The complete switch for electric traction systems substantially as described
or illustrated in the accompanying drawings.

Improvements in the Manufacture of Rosin Size and in Apparatus
therefor.
We, FRITZ ARLEDTER, and GEORGE HUTH, Engineers, both of 28, Queen Street,
in the County of London, do hereby declare the nature of this invention and in
what manner the same is to be porformed, to be particularly desoribed and ascer-
tained in and by the following statement:-
This invention relates to the manufacture of rosin size containing up to 50 per
ceut. of unsaponified rosin, easily miscible with cold water and free from impuri-
ties so that it is ready for use in the beating engine. The accompanying diagram
shows the arrangement of apparatus for this purpose, which is a part of our
invention.
In a boiler t, which is heated by steam coils or by a steam jacket, the rosin.
which may be of the commonest kind, is melted and forced by steam pressure
through the steam jacketted filter f into the steam jacketted pressure boiler b.
This boiler has a false bottom c from below which the contents may be pumped
by the centrifugal pumps pp respectively back into the boiler or into the tank ¹
through the pipes d'd' provided with cocks. The pipe e allows the pump 2 to
circulate the contents of tank t¹.
The process of manufacturing the size is as follows:-
Into the boiler 6 are introduced water to the amount of 20 per cent. of the
weight of rosin to be saponified and alkali amounting to 7 per cent. of the weight
of rosin.
When the alkali has dissolved the rosin is run in as above described and the
mixture is boiled under pressure for an hour while the pump » circulates the
boiling liquid by pumping it from the hottom into the top of the boiler. The
size is then blown into tank t¹ and about 2 per cent. of concentrated carbolic acid
or the like is added. The pump 1 is then set in motion and the contents of the
tank circulated for 10 to 15 minutes to mix in the carbolic acid, after which
the size is ready for use without further diluting in the beater.
Such size is destined for use in paper making, but the carbolic acid in this
small proportion is not objectionable for this purpose, inasmuch as it evaporates
from the paper as this passes over the drying cylinder.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. The herein described manufacture of rosin size casily miscible with cold
water by adding to the finished size a small proportion of carbolic acid or the like.
2. Apparatus for the manufacture of rosin size combined and operating as
herein described.

Packing for Eggs.
I, CARL MICHAEL FRANZKE, of House Emelien, Fishmarket Street, Kasan, Russia,
Eggs Shipper, do hereby declare the nature of my invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
My improvement relates to a packing for eggs formed of strips of wood shavings
instead of cardboard strips, which were hitherto used therefore by providing the
said cardboard strips with slits up to half their height and crosswise putting the
strips into each other, so as to form a frame of quadrangular shape with square
compartments for the eggs and adapted to be folded together.
Between the several frames thus made usually were put layers of straw or other
soft material.
Now my improvement on the old method consists firstly in the use of strips of
wood shavings for making the eggframes as before said, and secondly in the use
of a mat likewise of wood shavings put between each eggframe.
In the enclosed drawing is shown: In
Fig. 1 one of the woodshaving-strips with slits e at the under side, in
Fig. 2 one of the other strips with slits at the upper side, crosswise to be put
into the former strip,
Fig. 3 shows the strips put together to a frame and
Fig. 4 the latter folded together.
Fig. 5 shows the mat made of the wood shaving strips c and d,
Fig. 6 is a cut through the mat parallel to one edge and
Fig. 7a view upon the other edge of the mat.
Having now particularly described and ascertained my said invention and in
what manner the same is to be performed, I declare that what I claim is :-
-
1. A packing for eggs made of wood-shaving strips with slits half through,
by means of which said strips are put into each other so as to form a frame baving
square compartments for the eggs and adapted to be folded together substantially
as described.
2. In combination with a frame made of wood shavings and having square
compartments, a flat mat of wood shavings, as and for the purpose specified.

a coating of lacquer or other suitable varnish or material, which causes the lace
to firmly adhere to the moulding.
The lace is preferably treated with a petrifying solution to render it brittle when
the lace is applied to the mouldings in long lengths, such treatment enabling a
clean saw cut to be effected without dragging the lace.
Also the lace may be protected after fixing on the moulding by a coat of laquer,
varnish, or other suitable material.
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 application and use of lace and similar textile materials to mouldings
and the like, either before or after the same has been cut and made up into frames

or vapours into them after they have been raised to a glowing heat in suitable
retorts.
The gases are decomposed by the action of the heat, the carbon being eliminated
In some cases the said
and deposited in and upon the material to be treated.
gases may be replaced by substances, such as hydrocarbons of the fatty and
aromatic series, which develop carburetted gases or vapours under the action of
the heat.
Now, according to this invention, I apply the above graphiting process to
mixtures containing carbon (such as coke, charcoal, turf-charcoal and the like,
either in a loose or in a compact or moulded state) and refractory substances such
as magnesite, or the like, whereby refractory materials are obtained which will
be found superior to analogous products heretofore known, both as regards dura-
bility and resistance to high temperatures.
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 production of refractory material either in a loose or in a compact or
moulded state, by passing carburetted gases through a mixture of carbon and
refractory substances exposed to a glowing heat in suitable retorts, substantially
as described.
2. The modification in which, instead of gases, substances generating car-
buretted gases or vapours are introduced.

Improvements in or relating to Shafting Brackets or Hangers.
We, JOHN HOUSTON, Engineer, and ROBERT COLVILLE MATHEWSON, Engineer,
both of J. & R. Houston, Cartsburn Foundry, Greenock, N.B., Engineers and
Ironfounders, 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 brackets or hangers for carrying the
bearings of shafting of all descriptions and consists in so constructing the bracket
or hanger that, amongst other advantages, its weight is lessened without diminish-
ing its strength.
But in order that our said invention may be more readily understood and easily
carried into effect we will proceed to describe the same with reference to the
accompanying drawings in which
Fig. 1 is an elevation and
Fig. 2 a plan of a bracket or hanger constructed in accordance with my
invention.
Referring to the said drawings, in place of casting or otherwise forming the
bracket or hanger in one piece we employ a steel tube A the lower end of which
is threaded and passed through the bearing or bush seating, B, which may be
cast and formed of any convenient shape. The bearing B is then tightly
clamped in position by the nuts C C or the attachment may be effected in
any other convenient manner. In order to effect a stable and rigid connection
between the tube A and the plate D by which the bracket is carried, we form the
tube A with four or more slits in such a manner that the severed portions d thus
produced can be curved radially outwards and their ends rivetted or otherwise
attached to the plate.
The drawing shews the bracket having a single arm or stem but our improve-
ments are also particularly applicable to brackets having double arms that is to
say an arm or stem at each side of the bearing. In this latter case the shaft,
in place of having to be placed in position end on, can, by removal of the bear-
ing proper after the arms have been secured, be raised straight up and lowered
into position when the bearing has been replaced, thus facilitating the erection
of the shafting.
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:-
1. The bracket or hanger for shafts constructed substantially in the manner
as hereinbefore described and shewn in the accompanying drawing.
2. In brackets or hangers for shafts, the employment of an arm, or arms, of
steel tube, the upper end of which is formed with a number of severed portions
curved radially outwards and rivetted or otherwise secured to the attaching plate,

thereto by nuts, or other equivalent means, substantially as hereinbefore described
and shewn in the accompanying drawings.

I, FRIEDRICH WILHELM MAX HÄRTING, of 8, Erdmannstrasse, Leipzig-Plagwitz,
in the Empire of Germany, Locksmith, 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 slide cutting lathes employed at the present time the cutting of screw-
threads of extraordinary pitch is attended with considerable difficulty as the
first "calculation" wheel seated on the adjusting arm is driven by change gear,
the wheels belonging to which can only be made small, consequently for the
purpose of ensuring a high degree of velocity for the guide spindle, a large
number of small wheels have to be fixed to the adjusting arm, whereby not only
is the "calculation" rendered more difficult but the action of the machine also,
the wheels moreover being easily broken and causing much noise.
In particular cases, a second connecting gear must be employed, as the desired
pitch cannot be secured, with the assistance of the set of wheels.
The object of this invention is to obviate such difficulties.
The form and arrangement of the invention will be seen from the following
description with the assistance of the drawing, in which
Fig. 1 is a partial end view of a screw cutting lathe fitted with driving gear
according to this invention.
Fig. 2 being a side view of Fig. 1.
The essential feature of the invention is that to the head-stock a bracket a
is fixed, which supports a shaft 6 so as to allow of its rotating parallel to the
spindle of the head-stock. The shaft b carries at one end the gear wheel c,
which engages with the spindle wheel d, is of the same size, and consequently
produces transmission of motion at the same rate.
The gear wheel c engaging with the spindle wheel d forms the standing gear
for the set of wheels.
The other end of the shaft 6 serves for the reception of the first "calculation"
wheel g, with which the rest of the "calculation" wheels fixed in the adjusting-
arm carried forwards, engage so that the change-wheel ƒ does not come into use
at all.
On the shaft b wheels of the largest down to the smallest diameter can be
arranged, so that the cutting of screw-threads with extraordinary pitch can thus
also be effected with few wheels.
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:-
"
An apparatus applied to screw cutting lathes, for the purpose of facilitating
the calculation of the wheels to be inserted for certain screw pitches, com-
prising a shaft b, supported by a bracket a, arranged parallel to the turning

page_text: spindle, this shaft having, at its one end, a gear wheel c, engaging with the
spindle wheel d, and being of the same size, and at the other end the first "calcu-
lation wheel g, the wheels so held being interchangeable.

Improvements in the Construction of Bicycle Frames.
I, WILLIAM WALKER REID, of 20, George Street, Edinburgh, in the County
of Midlothian, North Britain, Civil Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in the construction of bicycle frames,
and consists in the employment of two rigid frames, one for the wheels; and the
other for the saddle post, cranks and steering handle, the two frames being
retained in their proper relative positions one to the other, by a suitable elastic
medium such as an arrangement of springs and links.
In the carrying out of the said arrangement, I employ a flexible steering head in
which the upper and lower parts are held in their relative positions by means of
springs and links; communication between the handles and steering wheel being
maintained by an arrangement of universal joints and a connecting link or
links of variable length.

COMPLETE SPECIFICATION.
Improvements in Signs for Advertising and like purposes.
We, WILHELM FRICKE, Contractor, and CARL FRICKE, Engineer, both of
Neustadt (Orla), Grand-Duchy of Saxe-Weimer, 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 follow-
ing statement:-
Our invention relates to signs designed to be used for advertising and like
purposes. A sign constructed according to our said invention presents the
peculiarity that it has a front and back plate with the letters or the like punched
or cut through. The intermediate space which remains when the two plates are
fastened together is used for inserting selenite, mica or like material in one or
more colours for the purpose of rendering the letters translucent.
In the accompanying drawing Figures 1 and 2 represent a front view and cross
section of such a sign by way of example as a street sign.
In carrying our invention into effect the front and rear plates ab are made
of sheet metal, wood or other weather-proof material and are united with each
other by screws c or other suitable means. The letters d are punched or cut
through the two plates. In order that the letters shall be rendered translucent,
as herein before stated, we place selenite, mica or like material e between the two
plates a and b.
Signs made in this manner are preferable to other signs of a similar kind or
class by reason of the durability and weather-proof properties they possess in
addition to permanent translucency.
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:-
A sign with translucent letters for advertising and like purposes, in which
selenite, mica or like material is placed between the front and rear plates having
letters punched or cut through them and consisting of sheet metal or other
weather-proof material, substantially as set forth.
