(Transparencies).
I, WALTER SYMONS, of 22 Haringey Park, Hornsey, County of Middlesex,
Publishers Manager do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement:-
-
This invention has for object, the preparation and use of two separate line
engraved or line printed transparent sheet like bodies which when a plain lined
one is moved slowly over or along or at an angle circularwise or otherwise but in
contact with a deviced line engraved or line printed sheet when exposed to the
light or by light from below, the lines of the upper in crossing those of the lower
changes of appearances, are visible and ever varying according to the line devic-
ing of the lower transparency. Thus, supposing the line engraving or printing of
the lower sheet represents a piece of machinery with the necessary line shading or
line toning of lights and shades, the movement of the upper plain lined trans-
parent sheet will give the effect as if the lines were in motion, in wave like form-
ation gradually increasing in proportion until lost to view, and where there are
several pieces of machinery with wheels and other line marked indications, some
of the lines when looked at through the upper moving sheet give the appearance
of some of the machinery as at work and some of the wheels rotating.
With a line engraving representing a Human Head, the Eyes, Nose, and Mouth
can be distorted and apparently moving when the upper plain lined transparent
sheet is moved on it, the same with a line engraving of a Ship or other still body,
it can be seen as if moving with line engraved water, the ripple of the surface
waves are apparent.
The effect is such that if one transparent plain line engraving or print be moved
slowly over the transparent yet deviced line engraving or print changes of appear-
ances visibly varying seem to be constantly approaching while others retire at the
same time mixing with others in a novel and amusing manner.
The material may be Celluloid Mica, Clear-Horn, Paper, or the like of a trans-
parent character.
nature of this
Having now particularly described and ascertained the
Invention and in what manner the same is to be performed I declare that what I
claim is
The production of illusory effect by the employment of two transparent sheets
of suitably line engraved or printed bodies, one of which has plain straight lines,

Improvements in the Stoppering of Bottles.
Year: 1897

page_text: Date of Application, 15th June, 1897-Accepted, 17th July, 1897
Improvements in the Stoppering of Bottles.
I, GEORGE SILLY, Clerk, 1 Victoria Street, Belfast, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to improvements in the stoppering of bottles.
The object of the invention is to so stopper medicine bottles, wine bottles, etc., as
to prevent their contents being tampered with for unlawful or dishonest purposes.
And in order that my said invention may be properly understood I have hereunto
appended an explanatory sheet of drawings, which shows, by way of example or
illustration, a medicine bottle having my invention applied thereto.
Fig. 1 is an elevation of the bottle and Fig. 2 shows the same bottle with the
shoulder and neck part in section.
When the bottle is being blown or moulded a weak part is made in the neck.
This weak part preferably takes the form of a V groove c running round the outside
of the neck b.
After the bottle a has been filled the ordinary cork e is inserted and pushed down
until the upper end of the cork is below the V shaped groove, a glass stopper dis
then inserted into the upper portion of the neck as shown at Fig. 2 and secured
immovably in position by means of "Diamond" or other well known and suitable
cement or its equivalent. An ordinary capsule f, if so desired, can be finally fitted
over the stopper d and the neck of the bottle as shown.
A space is left between the stopper and the cork and this space may be filled
with a liquid.
To open the bottle the capsule is first removed and then a sharp knock is given to
the top portion of the neck in order to break off the upper portion at the V groove.
When this has been done the cork e can be drawn in the ordinary manner.
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 consider novel
and desire to claim is :-
1. Fitting a glass stopper immovably in the neck of a bottle by means of cement
or its equivalent, for the purpose of preventing the contents of the bottle being
tampered with, substantially as set forth.
2. A bottle having the neck portion made with a weak part for the purpose of
being easily broken, substantially as hereinbefore set forth.
3. The application and use for the purpose of stoppering bottles of two stoppers
one of cork and one of glass the glass one being on top, substantially as and for the
purpose set forth.

page_text: I, OLIVER IMRAY, of No. 28, Southampton Buildings, Chancery Lane, in the County
of London, Chartered Patent Agent, do hereby declare the nature of this invention
(as communicated to me from abroad by The Farbwerke vormals Meister Lucius
and Brüning, of Hoechst a/Main, in the Empire of Germany, Chemical Manufac-
turers), to be as follows:-
By melting certain chemical compounds with sulphur and sulphur alkalies, dyestuff's
have been obtained of which the most prominent are probably the so-called, "solid-
black" and "vidal-black."
Each of these dyestuff's requires a special method of dyeing or can be fixed on the
fibre only in presence of certain agents.
"Solid-black" draws only.in presence of sodium sulphide, in a cold or boiling bath.
"Vidal-black," on the other hand, draws only with common salt and soda in a boiling
bath, and not in the cold.
My foreign correspondents have found a dyestuff which, with properties of fastness
equal to those above referred to, unites in itself the two modes of application, that is
to say, it dyes with sodium sulphide and with common salt and soda, drawing in both
a cold and a boiling bath. This variety of character renders the dyestuff of importance
in the dyeing of cotton.
EXAMPLE.
18 kilos. of sodium sulphide and 7 kilos. of sulphur are heated to 150° C. in an
iron vessel on the oilbath; the sulphur being dissolved and the melt having begun
to boil, which generally takes place within half an hour, 6 kilos. of dinitraniline 1.2.4
are gradually added while actively stirring, and then the heating is continued for
about 4 hours up to 180°-190° C. The melt is then taken out, broken up and
roasted for 4 hours in a flat iron pan in an oven at a temperature of 2300-240º C.,
finally a black porous mass of metallic lustre remains which dissolves in water with a
dirty green colour and may be directly employed for dyeing.
A similar dyestuff is obtained from dinitraniline 1.2.6.

page_text: I, GUSTAV HILLER of Zittau in the Kingdom of Saxony, Cycle 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:-
It is a well known fact that detachable pneumatic tyres cannot be used with
wood rims because the wood of the rim is liable to be split asunder by the pressure
produced on inflation of such tyres.
But the single tube or "hose pipe" pneumatic tyres which can be used with
wooden rims, cannot be readily repaired when damaged or punctured.
Now with the object of enabling pneumatic tyres to be reliably repaired, such
tyres are according to the present invention provided with a protective cover.
In Figure 1, a is a pneumatic tyre of this kind to which there is fastened one
edge of the protective cover b.
The air tube is placed in the deflated state upon the rim, and the protective
cover b is wound around it. Then on inflating the air tube, the cover is held by
the pressure of the air tube firmly between the air tube and the wheel rim as shown
in Figure 2.
For the purpose of facilitating the placing of the tyre upon the wheel rim, the
edges of the cover b may be provisionally held by means of button-shaped or
hook-shaped fastenings or closing devices.
In the case of damage or puncture, the tyre is taken off the wheel rim, the
cover 6 is pushed back, and the puncture in the air tube is repaired with a patch.
Then the cover is brought back into its original position. After the tyre has been
replaced on the wheel rim, the tyre can be re-inflated without any risk of the
patch which is covered over by the cover, becoming detached. It is not necessary
that one edge of the cover should be fixed to the air tube.
The security of the clipping of the cover can be still further increased by
making its edges take into recesses in the wheel rim or in the air tube as illustrated
in Figures 3, 4 and 5.
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:
shown.
(1) A pneumatic tyre constructed substantially as hereinbefore described and
(2) A pneumatic tyre provided with a protective cover for holding repairing
in which the nuntantive cover is clinned with one edge or with

A New or Improved Mechanism for Adding Up in Cash-controlling
Apparatus.
I, Dr. ADOLF FRANKE, of 23 Hagelsbergerstrasse Berlin in the Empire of Germany,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement :—
In cash-controlling-apparatus for adding-up English money that is pence to
shillings, and shillings to pounds, a special key has been used and adding devices for
the pence, shillings and pounds, or at least for the first two kinds of money using for
the counting-wheels of the shillings and pounds a simple carrying over of tens, by
introducing half pounds for counting.
Now by the present invention by means of only one key and counting device the
addition of pence to shillings and shillings to pounds and so on can be effected by
using counting-wheels divided into 60 equal parts for the adding mechanism.
The invention may be perforined as shown by the annexed drawing in which
Fig. 1 shows the counting wheels of such an adding mechanism, there being one
counting-wheel P for the pence, one counting-wheel S for the shillings and
3 counting-wheels ££10 £100 for the ones, tens and hundreds of pounds sterling.
Figs. 2, 3 and 4 show the three kinds of wheels, the periphery of each of which is
divided into 60 equal parts, so that on the periphery of the pence-wheel P, Fig. 4,
the numbers 0 to 11 can be arranged five times; on that of the shilling-wheel S,
Fig. 3, the numbers 0 to 19 can be arranged three times, and on that of the pound-
wheels £, Fig. 2 the numbers 0 to 9 six times. In accordance with this division
during a complete revolution the pence-wheel P carries over five times one shilling,
the shilling-wheel S carries over three times one pound and the pound-wheels £ carry
over six times the tens of pounds. For this purpose may be used any convenient
carrying over mechanism, which is operated according to the dotted lines in
Figs. 2, 3 & 4 five times for the pence-wheel P, three times for the shillings-wheel S
and six times for the pounds-wheels £.
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:
The new or improved adding mechanism for cash-controlling apparatus consisting
of counting-wheels divided into 60 parts, in order to carry over pence to shillings and
shillings to pounds, as well as to carry the tens for the counting-wheels of the
pound sterling, all substantially as illustrated and described.

"An Improvement in Electric Plug Contacts."
We, HENRY CHARLES GOVER, Secretary, of The Edison and Swan, United
Electric Light. Company Limited, MATTHEW SELBY BLAIR, Electrician, and CHARLES
FARADAY PROCTOR, Electrician, all of 36 Queen Street, Cannon Street, in the City
of London, 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 electric plug contacts as they are usually constructed, there are holes into
which the plugs are inserted. These holes are liable to become more or less filled
with dirt, preventing the plugs from being properly inserted or from making good
contact. According to the present invention the contact appliance is provided with
spring plungers which when the plugs are withdrawn are caused by the springs to
follow so as to quite fill the plug holes.
Fig 1 of the accompanying drawing is a section of a double plug contact, accord-
ing to this invention, shewing the plugs inserted.
Fig 2 is a section shewing the plugs withdrawn.
Fig. 3 is a plan of the base with the cover removed.
Fig 4 is a plan of the cover.
On a base B of insulating material are fixed two socketa S, S₁ each in metallic
connection with a terminal TT". Within each socket is fitted to slide a spring
plunger PP. All these parts are enclosed within a cover C having holes through
which the sockets SS' extend almost to the upper surface of the cover.
The plugs A A' which are split up a certain distance from, their points are held
in a cap D. These plugs are provided with nuts to take flexible or other connections.
The cover C is provided with a pair of holes H for the purpose of holding the
cover down.
Although we have shewn a contact appliance for two plugs obviously a similar
construction could be adopted for other number of plugs.
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:-
An electric contact plug constructed and operating substantially as and for the
purpose set forth.

page_text: I, HENRY HALE, of Greenvale, Ardee County Louth, Ireland, Corn Merchant
and Miller, do hereby declare the nature of this invention, and in what nianner the
same is to be performed, to be particularly described and ascertained in and by
the following statement:-.
This invention relates to improvements in connection with driving belts, and has,
for its object to provide a simple and secure means by which the ends may be
connected together. The device is intended to be used in place of the faces
commonly employed and it is of such a simple nature that the parts can be con-
nected together by any person without requiring skilled labour.
The device I propose to employ is formed from a small strip of metal which is
bent or doubled so as to form a double stem with a head. The belt is. formed
with a number of slits which are equal in length to the width of the fastening
and the latter is passed through one of these slits in each end of the belt. After
passing through the ends of the stem are bent round so as to prevent the fastening
being withdrawn and as the metal is of considerable strength there is no danger
of the fastening coming out. A number of these articles is employed for each
joint according to the width of the belt, two rows being preferably used and one,
two or more fastenings in eacli row.
In order that the invention may be more clearly understood reference is had
to the accompanying sheet of drawings in which Fig. 1 shows the blank front
which the fastening is made, Fig. 2 shows the complete fastening, and Fig. 3 is
a section of a belt connected in the manner described.
As shown in Fig. 1 the blank consists of a strip of metal, the ends of which are
preferably cut slightly narrower than the body. This strip is bent or doubled
as shown in Fig. 2 so as to form the head A and the double stem B. The two
parts of the belt C are formed with slits through which the stem of the fastening
passes. As shown in Fig. 3 after the stem is passed through the extremity b of
each leg is bent back preventing the stem being withdrawn.

Vue, West Hartlepool in the County of Durham, 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 has for its object a device for cleaning school slates for the
purpose of removing matter which has been written or drawn thereupon.
It will be understood from the following description, reference being had to the
accompanying drawing, in which a perspective view of the device is shown.
It consists of a piece of wood forming a backing A, coloured or otherwise, on
one face of which is secured a piece B of leather, indiarubber or other suitable
material, or the leather or rubber may be on both sides if so desired.
To use the article in connection with school slates, all that is necessary is to
rub the surface of the slate with it, when the writing or drawing will immediately
disappear. The use of water is unnecessary, thought a breath from the mouth
applied to the surface of the slate may quicken the operation of cleaning. It
leaves the slate free from grease, requires very little pressure, and the cleaning
can be effected almost instantaneously. The backing may be provided with a
suitable handle if so desired.
The invention can if desired be used largely as an advertising medium, the
article in such case being made cheap and sold at a small price with an advertise-
ment printed or displayed on the face of the backing.

I, HEINRICH KOENEMANN, of Augustastrasse 17, Barmen, 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 object of this invention is to provide for means by which the jaws in vices can
be adjusted angularly to each other.
The invention is represented in the accompanying drawing, in which :
Fig. 1 is an elevation view representing the whole vice with its adjustable jaws;
Fig. 2 is a section through the movable jaw;
Fig. 3 represents the movable jaw detached from its spindle-base.
The essential feature of the invention consists in the fact that one jaw of the vice
is pivotally arranged upon a disc in such a manner that the said jaw admits of its
being angularly adjusted relatively to the other jaw.
Upon the free end of the spindle base a a disc b is arranged which serves as a slide-
surface for the jaw c, which latter is provided with a disc d corresponding in shape to
that of the disc b.
The spindle base a and the movable jaw c are connected with each other by means
of the spindle e which simultaneously serves as a guide or pivot, on which the movable
jaw c is adapted to turn.
For fixing the movable jaw c in any desired position, several screw-bolts f are
provided, which are rigidly connected to the disc b and pass through a slot-guide g,
arranged in the disc d.
For the purpose of displacing the jaw c, the screw-bolts f are detached, subsequently
the jaw c is angularly adjusted to the stationary jaw according to the shape of
the piece or blank to be worked, and is then secured in this position by tightening the
screw bolts.
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 vice presenting this characteristic feature that one jaw c and the spindle-base a
are constructed in two separate parts, provided with slide-surfaces b and d, which said
two parts are movably connected by a guide-spindle or pivot e, and that, through the
medium of screw bolts f, the movable jaw c can be secured in any position relatively
to the stationary jaw.

Improved Means for Distributing Manures and similar Substances.
We, ALEXANDRE HEBERT, of 66 Rue Gay Lussac, Paris, and GEORGES TRUFFAUT,
of 39, Avenue de Picardie, Versailles, both in the Republic of France, Chemists,
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 our invention is an improved means for distributing manures
consisting in compressing soluble manures of all kinds and either enclosing them
in receptacles or not so as to obtain small pastilles of compressed manure of a
fixed weight enclosed if desired in one or more metallic coverings in such a way
that they are especially applicable for use in the cultivation of garden plants and
can also be employed in general agriculture.
Hitherto both in agriculture and horticulture manures have been distributed
in a pulverulent state or dissolved in the water used for irrigation.
In both cases it may well be that a considerable quantity of manure is wasted being
carried off with the drainage water and further when manures are distributed in
irrigation water errors of weight and quantity may be introduced.
To avoid such inconveniences, we distribute manures in the form of pastilles
which we prepare by previously mixing the dry manure intimately with dry,
clay enclosing it if desired in a metallic covering and then compressing it under a
pressure of several thousand pounds.
The ingredients which enter in the pastilles are very varied since as is well
known each plant requires a special kind of manure.
The following is an example:-
Nitrate of soda
Phosphate of ammonia
Sulphate of potash
Nitrate of ammonia
Phosphate of lime
Sulphate of iron

Sulphate of magnesia
Chloride of ammonium

The chemical products are mixed together and introduced into a case or shell
preferably of thin soft metal and the metallic shell is compressed in any ordinary
apparatus.
Pastilles so obtained are ready for use either in agriculture or horticulture.
Under these conditions the diffusion of the manure only takes place gradually;
and the manure is only exhausted in the course of several weeks or even several
months according to the number and thickness of the metallic coverings in which
it is contained.
The advantage of this slow and gradual diffusion is that it allows the regular

Improvements in Tooth Picks.
I, HENRY THOMAS TISSINGTON of Aspen, County of Pitkin, Colorado, U.S.A.,
Bookkeeper, 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 tooth picks of that class comprising
a metallic body portion with arms and a string or band secured thereto and
bridging the same.
In the accompanying drawing Fig. 1 is a perspective view of the tooth pick of
this invention and Fig. 2 a section through the same.
In carrying out my invention I take a piece of suitable material such as wire
of any suitable diameter and of a length required to make a toothpick of the
desired size. This is bent to form the two curved arms which terminate in
closed eyes
bor the eyes may be formed by flattening the wire at the ends of the
arms and forming holes therein, or the tooth pick may be made of flat material
in which the holes are made. The wire is twisted round and together to form the
handle which may be of any desired length. The twisting not only gives
strength but also a better hold, so that the toothpick will not slip in the hand.
or
C is a thread or piece of dental floss or other suitable material for taking
between the teeth. It is passed through the eyes in the ends of the arms
U shaped part and secured to the twisted handle as shewn.
From the foregoing the manner of use will be readily understood.
The bend of the wire at the middle of its length is drawn out to form a pointed
pick.
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:
The toothpick herein described, formed of a single piece of metal bent at its
centre and elongated and sharpened to form a point and twisted from its point to
formi a straight handle, the material branching from the end of the handle forming
a substantially shaped portion with the ends of the material bent to form eyes
and having a thread passed through the eyes and twisted about, and secured to
the twisted handle at the point beyond the junction thereof with the U shaped
portion, substantially as described and shewn.

County of London, Chartered Patent Agent, do hereby declare the nature of this
invention (as communicated to me from abroad by the Farbwerke vormals Meister
Lucius and Bruning, of Hoechst */ Main, in the Empire of Germany, Chemical
Manufacturers), to be as follows:-
My foreign correspondents have found that 5-alkyloxy-1 phenylpyrazoles may be
transformed by heating into 2-alkylphenyl-pyrazolones, as for instance in the
following manner.
1-phenyl-3 methyl-5 methoxypyrazole described by Knorr (Berichte 28. p. 717)
is heated in a closed vessel for several hours to 2500-260° C, 1-phenyl 2-3-dimethyl-
pyrazolone is extracted from the cold product of reaction by means of water and
separated from the solution with benzene. Any phenylmethylpyrazolone that
may be formed is removed from the benzene solution by shaking with soda-lye
and the 1-phenyl 2-3-dimethyl-pyrazolone is obtained by distilling off the benzene.
In a similar way 1-phenyl 2-ethyl 3-methyl-pyrazolone is obtained from 1-phenyl
3-methyl-5-ethyloxypyrazole.

An Improved Collapsible Cardboard Box."
Year: 1897

page_text: Date of Application, 24th July, 1897-Accepted, 4th Dec., 1897
"An Improved Collapsible Cardboard Box."
I, EMANUEL STERN, of 71 Thieboldsgasse, Cologne 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 concertina-like collapsible box which appears particularly
suitable for containing hats.
A collapsible cardboard box has the considerable advantage over those hitherto
employed that it requires very little space for storage, which circumstance appeals
especially to large shops and stores which can better employ their expensive store
room than in storing empty boxes.
A form of construction of the object of the invention is shown in the accompanying
drawings, in which,
Figure 1 is a longitudinal section ;
Figure 2, a plan view after removal of the lid ;
Figure 3, a cross section of the collapsed box and
Figure 4, a view in perspective of the expanded box.
This box has at the bottom two diagonal grooves or creases a and b and a third
crease c which connects two end creases d and e, see Figures 2 and 4. By means of
these creases or grooves the bottom and the two ends may be pressed in in such a
way that the box when collapsed only occupies a height of about 3 centimetres.
In order to collapse the box the lid i and the internal stiffening frame ƒ are
removed when the bottom is easily pushed upwards by means of the thumb causing
the ends to fold inwards at their creases d and e.
The stiffening of the box, when in an expanded condition, is attained by means of
a frame f of wood, sheet metal or wire which is laid on the bottom of the same, which
frame prevents the bottom being pushed in and the box being thus collapsed.
Cords gh are attached to the two grooved sides, which cords securely hold these
sides and also the lid i.
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 concertina-like collapsible box with grooves or creases in the bottom and ends,
and a frame adapted to be inserted as a stiffening piece, substantially as herein before
described.

COMPLETE SPECIFICATION.
Improvements in or relating to Automatic Syphon Flushing Tanks.
We, GEORGE CRAPPER and ROBERT MARR WHARAM, both of Marlboro"
Works, Marlborough Road, Chelsea, S. W., in the County of Middlesex, Sanitary
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 object of the present invention is to ensure the starting of the syphons-
of automatic flushing tanks directly there is a sufficient head of water therein.
Many water companies now require these tanks to be fitted with a drop by drop-
supply, the result of this extremely gradual filling of the tank being that the water
frequently merely trickles away continuously through the syphon, without starting
it, when the tank is full.
Now according to our invention, we provide an air outlet valve at the top of the
syphon the said valve being automatically operated by a lever and float. Directly
there is a sufficient head of water in the tank this valve is lifted by the lever
and float and the compressed air in the syphon immediately escapes therethrough
causing a sudden rush of water through the syphon which is thus started with.
certainty.
In the accompanying drawings,
Fig. 1 represents the application of our invention to an automatic flushing tank
fitted with an annular syphon.
Fig. 2 shews the application of the invention to an automatic flushing tank
having a tubular syphon.
Fig. 3 is a detail.
Similar letters refer to like parts in all figures.
A represents the syphon and B is the air outlet valve at the top thereof the said
valve being automatically operated by the lever a and float b. So soon as there is.
a sufficient head of water in the tank C, the valve B is opened by the lever and.
float thereby permitting the compressed air in the syphon to escape and causing a..
sudden rush of water through the syphon which is thus started with certainty.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner, the same is to be performed, we declare that what we
claim is :-
In an automatic syphon, flushing tank providing the top of the syphon with a.
float operated air outlet valve, substantially as described and for the purpose-
set forth.

page_text: Date of Application, 8th July, 1897-Accepted, 9th Oct., 1897
Improvements in the Construction of Window Frames and Sashes,
and in Apparatus therefor.
I, CARL BRAUNSTEINER of No. 153 Gladbeck, Germany, Architect, do hereby
declare the nature of this invention and in what manner the same is performed, to
be particularly described and ascertained in and by the following statement:-
My invention has reference to a machine for cutting angular grooves into the
frames of windows and sashes for embedding the angle irons. In order to make my
invention more easily understood I have shown in Fig. 1 of the accompanying
drawing a top view of the improved machine, in Fig. 2 a bottom view and in
Fig. 3 a side view of same.
The ground plate a, having the rectangular guide slot b, carries a pin c, engaging
the slot e in the bar d. The latter thus can swing around the pin c and can also be
moved lengthwise. The slotted bar d carries a pivot f upon which turns the
fly-wheel q. On the inside of the fly-wheel a toothed wheel h is provided,
engaging the pinion which is fastened on the axle k. This axle k is journalled in
the bar d, runs through the rectangular slot 6 and carries on its other end the
cutter l. If the toothed wheel h is rotated by means of the handle m, the pinion i
and consequently the cutter will also be rotated. The cutter is now moved along
in the rectangular slot 6 by guiding it by means of the bar d. The window frame to
be grooved, shown in dotted lines in Fig. 1, is held in place by means of the clamp o,
pressing the window frame against the ground plate a. The angle iron to be put in
the groove has the shape of the slot b, i.e. rounded ends and a rounded corner.
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 carving-machine for hollowing out the angular grooves of window frames
the combination of a bar d, being guided on the ground-plate a by means of the
pin c engaging the slot e and the cutter k, being guided in the rectangular slot b,
substantially as and for the purpose set forth.
2. Angle iron, having rounded ends and a rounded corner, as described.

page_text: GEORGE HARTLEY West Field Workington Cumberland Photographer 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 :-
Description of the shutter appliances I wish to have patented; are fitted outside of
shutter case and are as follows
Lever for the Release of Roller Blind Shutters with spring attached to Lever to
keep same in Position also a wheel and pin to which is applied the Lever, also a pawl
to hold the above Lever in position when focusing. The top shutter shaft is brought
through the side of the case, to which is fitted a wheel on the outside, and on the face
of the wheel a pin is fixed to which is applied a forked Lever, the Lever is kept in
position against the pin by a spring, the same is released for work by air pressure.
The accompanying drawing shows the feature of novelty claimed, viz. the lever A
with spring E attached; the wheel or disc D with a pin shown in position for
instantaneous exposure at C or for focusing or time exposure at H; the pawl F is used
to keep the lever A in position when focusing.
The shaft B is the end of the top roller blind shaft on which camera shutters and
their revolving motur (as commonly used) are fixed.
This shaft end is brought through from the inside to the outside of the shutter
case. To it is fixed a wheel or disc D into which a pin is fixed so as to project from
the face of the disc D, to this pin the ends of the forked lever A are applied as
occasion requires viz., Prior to the shutters being worked for an instantaneous
exposure, the pin would be held in position at C: but, if either focusing or time
exposure is in use the position of the pin and lever A would be as shown in dotted
lines at H. An indiarubber air ball and tube at G. is applied to the single end of the
lever A.
When inflated-by pressing this air ball causes the lever A to release the disc pin
at C for instantaneous exposure, or hold the disc pin in position for time exposure or
focusing at H, in order however to allow the photographer freedom with both hands
when focusing, a pawl F can be used to keep the lever A in position.
The spring E forces the lever and holds in such a position as is suitable for being
actuated upon by the air ball G or the pawl F.
To take an instantaneous photograph the operator merely grasps and presses the air
ball and at once releases it.
For time work the operator grasps and presses the air ball, holding it as long as
may be 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 :—

page_text: Improvements in Carpet Sweepers.
We JONATHAN BARNES, RICHARD WALTON KENYON and WILLIAM HENRY KENYON,
of the firm of Entwisle & Kenyon, of Ewbank Works, Accrington, in the County of
Lancaster Machinists, 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 carpet sweepers whereby the band or
fender of rubber or other material passed round the sweeper may be adjustably
secured.
It consists essentially in securing this band or fender by means of detachable spring
clips or fasteners and in clips designed for the purpose.
It will be fully described with reference to the accompanying drawings.
Fig. 1. End elevation of sweeper.
Fig. 2. Section of end showing spring clip in position.
Fig. 3. Side view of spring clip detached.
Figs. 4 5 and 6 show modifications in the shape of the spring clips.
The casing A the wheels B and the brush Care all of the ordinary construction.
The rubber band or fender D is passed round the sweeper and over the end bars E
in the usual way.
In each of the bars E we cut one two or more notches e to receive a spring clip.
Around the bar E at intervals embracing the fender band D we place a spring clip F
which grips the bar E and secures the band D in position. When it is desired to
remove the band D for repairs or to alter its position the spring clips F can be
removed and then replaced.
We at present prefer to construct the spring clip F as shewn in Figs. 2 and 3 with
an elongated end by which it can be raised by the finger to remove or release it.
It is curved or inclined at ¹ to enable it to be pressed or sprung over the bar. This
curve or incline may be at the bottom of the clip in addition to or instead of at the
top. The lower end 2 is hooked to engage the bar, it inay be placed on the bar in
the position shown or may be reversed. The clip may be made in either of the forms
shown in Figs. 4, 5 or 6, or in any suitable or convenient shape.
The spring clip F is preferably inade from spring steel as shown in the drawings
though it may be made from steel wire of flat, round, half round or other convenient
section, or it may be made of any other suitable metal or material.
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. The securing of the rubber band or fender around carpet sweepers by spring
clips substantially as described.
2. In a carpet sweeper the combination with the end bars E provided with notches e
of a spring clip F passing over the edges of the bar and embracing the fender band D
substantially as described.
3. The spring clips for securing the fender bands around carpet sweepers substantially
as described and shown.
