"IMPROVEMENTS IN APPARATUS FOR REGISTERING FARES,"
This invention refers to registering alarm punches to be used for punching
tickets and registering one or more fares on and by the same ticket and the
invention relates particularly to improved mechanism for causing the ticket
operated on to progress after each punching and so present another part of its
surface to the action of the punch, at the same time locking the ticket and
preventing its withdrawal until wholly punched and record made-I carry out the
invention by making the punch with an alarm and recording devices and I combine
therewith a pair of toothed or other convenient shaped wheels for embracing and
carrying forward the ticket and I operate said wheels by means of springs attached
to the punching bar or punch itself, or by other suitable means-I also actuate the
recording wheels and their devices (which in themselves may be of any ordinary
description) by a spring or springs attached to the punch.

According to these improvements water is heated to a temperature not greatly
exceeding 212 degrees Fahrenheit in a suitable vessel This heated water is forced
by means of a pump or other mechanical appliance into a pipe or pipes kept at a
high degree of heat by being placed or arranged in a furnace and flue of the fire
which heats the boiler.
The water on being forced into the pipes is rapidly converted into steam which
can be safely utilized at a high pressure.
There being little or no pressure on the vessel which heats the water all danger
of explosion is avoided.
The advantages obtained are economy of fuel. Safety with steam under great
pressure. The rapidity with which steam of any desired pressure can be produced.
The ease with which the pressure of the steam can be either raised or lowered
almost instantly. The waste steam from the cylinders of the engine being
available if desired to heat the water in the boiler and The ability to generate and
store steam with safety and economy at a pressure greatly in excess of that in
general use.

WEAVING
"
This Invention relates,
Firstly To that part of the picking mechanism employed in putting the picking
tappets in and out of position for picking
Our Improvements for effecting this purpose consist in the employment of a
vertical reciprocatory bar having a hinged toe piece at its lower end, and its upper
end provided with a short vertical connecting rod placed in contact with a cam on
the crank shaft for imparting the necessary reciprocatory motion
The connecting rod is provided with a spiral spring capable of adjustment by
nuts, so as to allow the parts to yield when there is stiffness
A horizontal rod connected to a horizontal square bar for sliding the picking
tappets on the picking shaft is also employed-When the picking tappets are
required to be in a certain position for picking they are slided upon their shaft by
the action of the hinged toe piece, The hinged toe piece is moved in one direction
by a flat spring and in the other direction by a bell crank lever operated when
required by a jacquard or pegging cylinder placed above the top rail of the loom
When the horizontal sliding bar for sliding the tappets has been moved in either
direction, it is firmly held in that position by a locking mechanism whilst the
loom is picking-The locking mechanism consists of two levers which are lifted at
each revolution of the tappet shaft by a cam thereon, but immediately the cam
has moved away one of the locking levers is caused to lower by a spring into a
notch formed in the sliding bar, and is firmly held there until released by the
cam.
By this means the picking is made positive and the holding bar keeps the parts
rigid whilst the loom is picking

page_text: Secondly Our Improvements refer to the mechanism employed for supporting
the piece beam and allowing the shaft thereof to lower as the beam becomes larger
in diameter by the winding on of the woven material
For this purpose we employ a hinged segment provided at one side with a
projecting arm or finger, upon which the shaft of the piece beam rests, and on the 5
opposite side thereof are ratchet teeth into which a holding catch bears-A strong
spring in connection with the segment is employed for bearing the weight of the
beam which as it becomes larger in diameter depresses the forward end of the
segment, thereby causing the said spring to yield but it is connected in such a
position on the segment, that it is soon past the hinged centre thereof, and 1
although the beam may continue to increase in diameter and depress the forward
end of the segment, the spring is stretched no longer thereby.

WILLIAM ALFRED PHILLIPS of The "Lea" Telegraph Works, Hackney Wick
in the County of Middlesex Electrical Engineer AN IMPROVED METHOD FOR
INSULATING WIRES FOR ELECTRICAL PURPOSES
The object of this Invention is an improved method of covering or coating wire
with an insulating material of strip form laid longitudinally and the seam secured
by heat or other means said,covered or coated wire being then encased in the same
or other material by braiding or otherwise.
This Invention consists essentially of the employment of a strip of Gutta percha
or other insulating material to cover the wire longitudinally and at the same or at
a separate operation to cover or braid the coated wire with cotton or other thread,
it is afterwards passed through Melting Ozokerit paraffin, wax or any other insula-
tion. The Gutta percha covered wire aforesaid is passed through a heated chamber
to ensure that the edges of the Gutta percha strip are perfectly joined; the above
insulation may be protected in various ways with Jute, Hemp or Asbestos.

MENTS IN ELECTRIC ARC LAMPS," a communication to me from Hardman Arthur
Earle, of London, England, at present residing in Hannover, Prussia, and Ewald
Goltstein of Hannover Prussia,
Our invention relates to electric arc-lamps in which the distance of the two
carbons from each other is regulated by the flow of a liquid controlled by the
electric current, and the chief improvement consists in operating, by means of the
current, a piston adapted to exercise a pressure on the liquid, and thereby to
separate the carbons when the lamp is switched into the circuit, the piston acting
subsequently as valve to limit the flow of the liquid according to the length of the
luminous arc.
The holder of the upper carbon is connected to the rod of a piston working
in a cylinder which contains glycerine or other suitable liquid. This cylinder
communicates at its base with a small cylinder carrying at its top a reservoir and
provided with a channel leading from a point of its side to the reservoir. Within
the small cylinder there is a piston adapted to open and close the said channel.
This piston is joined to a movable and balanced core of a solenoid or differential
solenoid inserted into the circuit of the lamp, or it is placed in any other known
manner under the control of the current, whether such control be direct or indirect,
and the parts are so arranged that, when the lamp is burning and the arc is of the
proper length, the piston will be in a position to keep the channel from the
cylinder to the reservoir closed; while on the other hand, when the distance
between the carbons becomes too great, the current operates to raise the small
piston or to allow it to be raised, so that it will then open the said channel. In
the first case the upper carbon remains stationary, whereas in the second case
liquid flowing from the large cylinder into the reservoir, the large piston with the
upper carbon will sink and the proper distance between the carbons will be
restored,

page_text: On switching the lamp into circuit, the action of the current at first causes the
small piston to be pushed so far inward in its cylinder as to raise the large piston
and thereby to separate the carbons.
In order to allow the liquid to flow back from the reservoir to the large cylinder
when the piston of the latter requires to be raised for the purpose of providing the
lamp with new carbons, a channel with a suitable valve in it is provided for
between the reservoir and the space containing the regulating liquid. This channel
may be arranged to pass through the small piston,

"IMPROVE-
This Invention has for its object improvements in cocks or valves, applicable for
water, steam, gas, or other fluid, and is specially applicable for use where the cock
or valve leaks or requires repairs, same being effected according to this my
Invention without interfering with the service of the cock or valve.
In carrying out my Invention, I adopt mainly the following arrangements :-
The body of the cock or valve is made adjustible, said cock or valve being
provided with suitable ports or openings for the passage of the liquid or fluid.-The
cock or valve is closed in the ordinary way by raising or lowering the valve or
plug. When the body or outer shell is turned so that the port or opening in same
is at such an angle as to meet the portway a continuous supply is ensured, whilst
the valve or valves is or are withdrawn for repair or otherwise.
IMPROVEMENTS IN MORTISE AND OTHER LATCH LOCKS

ALEXANDER MELVILLE CLARK, of the firm of A. M. and W. Clark of
53 Chancery Lane in the County of Middlesex, Fellow of the Institute of Patent
Agents IMPROVEMENTS IN MORTISE AND OTHER LATCH LOCKS [communicated to
him from abroad by Messieurs Gollot frères of Paris, France Manufacturers]
This Invention relates to improvements in door and other locks especially
mortise locks, in which a spring latch is operated by a follower on the spindle of
the knob or handles and it has for its chief object to increase the bearing surfaces
of the spindle follower, and thus prevent it wearing loose. In these locks the.
follower usually turns in mere holes made in the sides of the lock case the wearing
surfaces presented by its bearings being therefore only equal to the thickness of
the sheet metal case.
The follower and with it the spindle carrying the knobs or handles consequently
soon work loose.
These objections are avoided by this improved mode of mounting the follower
which consists in forming a deep groove in each of the two end faces of the
cylindrical boss of the follower concentric with the axis of the spindle hole, and in
providing each of the side covers or plates of the lock case with an inwardly
turned flange or circular rim around the hole in which the follower turns, these
flanges coinciding with and fitting in the circular grooves of the follower. By this
means each journal of the follower is provided with two cylindrical wearing
surfaces the one within and the other without the flange, each of these surfaces
being of twice, thrice, four, or more times the extent of that presented by a
mere hole in the lock-casing so that the wear of these parts is consequently
almost nil.
A particular feature of this form of bearing is that the thickness of the lock is
not increased there being no external projection which is essential in the case of
mortise locks, and the follower itself is in no way weakened. The follower may
ID 577

page_text: have one or two arms so as to act on the latch in one direction only or in either
direction as usual.
Another improvement relates to latches such as those used on shop doors which
are operated by lever handles and consists in the combination with a follower
mounted as above described of a clock spring coiled about the boss of the follower,
and so applied as to raise the handles sharply when released by the hand, the latch
itself being projected by another spring.

This invention relates to an improved method of distending the net employed in
the game of lawn-tennis whereby the same can be adjusted in height and torsion
to the greatest nicety without having recourse to the usual pegs which injure tho
surface of the ground and consists in the employment of a cam so mounted on the
poles at either end that the net rope can be pulled through in one direction but
which cam locks itself fast upon the rope as soon as it is "let go" or released
the rope in this case being by preference passed over pulleys mounted in the poles.
This arrangement of supporting the net is applicable to the ordinary lawn-tonnis
court and also permits the game of lawn-tennis being played upon a diminished
scale in-doors say upon a dining or billiard table in which case the poles are
supported in brackets clamped at cither side of the table and between which poles
the net is distended, the ends of the rope being either secured together by an
elastic medium or fastened in any convenient manner beneath the table or may be
secured by the clamping apparatus hereinbeforo described or by hanging weights.

JOSIAH REDPATH of Sheffield in the County of York. "A NEW OR IMPROVED
METHOD AND MEANS OF ADVERTISING
"
This Invention has for its object the exhibiting of advertisements and other
similar matter, in a novel, attractive and most advantageous manner, and it
consists in placing reading or the matter to be exhibited or advertised within a
specially shaped and adapted carafe, bottle, or vessel of glass or other transparent
material so that such matter becomes somewhat magnified when water or other
transparent liquid is placed in the carafe bottle or vessel. Consequently when
such carafes bottles or vessels are placed upon the dining tables of restaurants or
hotels or the bars of taverns, inns, or coffee houses, or other places of public resort
the advertisements within the vessels are rendered prominent and continually
attract the notice of the public.
In carrying out the Invention the carafe, bottle, or vessel is specially formed
with the middle part of its base rising upwardly within the interior of the vessel
like an inverted cup, and forming a cavity which cavity may be made of conical,
square or other desired and convenient form. The matter to be advertised or
exhibited is fixed within this cavity, with the reading or matter facing outwards
into the interior of the vessel and after fixing the advertisements the cavity may
be filled up with cement or other suitable material to prevent the advertisements
being tampered with and by making its base solid, the vessel will be rendered less
liable to be overturned.

This invention is designed to save coals, to save the trouble of continually
replenishing the fire, to burn the smoke in good part, and to dry the coals before
using. It consists in an arrangement of fireplace with a bottom capable of being
raised and lowered through an inclosed space or short shaft below, and in other
apparatus connected therewith as hereinafter indicated.
The mode of using it is as follows. The bottom being lowered, the entire shaft
and fireplace is filled with fuel and the fire lit at top; as the fire gets low the
entire column is periodically raised. When the floor of the column of fuel reaches
the level of the bottom of the fireplace, a plate or temporary bottom is shoved in
over it by suitable mechanism, and the true bottom lowered and filled up with
fuel again. At night the bottom is lowered, till the fire descends below the
temporary bottom, when the temporary bottom is brought forward covering it
and smothering the fire. A space behind the fire is in some cases left for ashes
with a shoot to the front. In other cases both the real bottom and the false or
temporary bottom are made sloping downward in front and the ashes can be poked
out to the front. The mechanism I prefer for raising or lowering the bottom, or
for propelling the temporary bottoni is a rack and pinion and a windlass arrange-
ment, but a screw or even suspending mechanism can do for the raising and
lowering mechanism, and levers for the other.

This invention relates to improvements chiefly applicable for hose couplings
whereby the coupling and uncoupling of hose pipes can be effected more quickly
and easily than hitherto. The improvements are also applicable to couplings for
other purposes.
In carrying out my invention the inner circumference of the female portion of
the coupling is formed or provided with a suitable number of lugs or projections,
the male portion of the coupling being provided with inclined projections around
its periphery with spaces between the ends of the projections, such spaces forming
slots and corresponding with the lugs of the female portion of the coupling. The
end of the male portion of the coupling is truly faced so as to fit against a corre-
sponding face in the female portion of the coupling and form a tight joint when
the coupling is closed, or a washer of suitable material such as rubber or leather
may be employed between the faces to form the joint.
The female portion of the coupling is provided with a spring key or bolt adapted
when the coupling is closed to pass into one of the spaces or slots between the
projections of the male portion of the coupling as hereinafter described.
The parts of my improved coupling are connected to hose pipe (or to other
articles to be connected together) in the usual manner, and to connect or couple the
hose together, the male portion of the coupling is passed into the female portion,
the lugs on the latter passing along the slots or spaces on the male portion of the
coupling, and the parts being then slightly turned one on the other the herein-
before described key or bolt will automatically slide into one of the herein before
described slots and the parts will be held together and a tight joint will be formed
by the faces of the coupling being drawn tightly together by the lugs sliding over
the inclined projections as the parts are turned.
To uncouple it is simply necessary to draw back the herein before described key.
or bolt and then to turn the parts of the coupling until the lugs correspond with
the slots when the parts can be drawn asunder
By this arrangement I provide a coupling which may be termed automatic in
its action, which is simple in construction and is not liable to get out of order.

"IMPROVEMENTS IN SOLDERING IRONS,"
My improved soldering iron consists of a copper bit of suitable size and shape
having a recess on the top side, said bit is rivetted or otherwise secured to a hollow
boss or ferrule which covers part of the copper bit, the boss or ferrule either forms
part of or is secured to n hollow receptacle of suitable shape and length bored
slightly conical, inside, the greatest diameter being the farthest from the copper bit,
the receptacle is screw-threaded exteriorly a part of its length, and is screwed into
a cap of iron provided with a wood handle, when in use solder is placed in the
recess in the copper bit after it has been heated, and after the ends of the wires to
be soldered together have been treated with a solution of spirits of salt or its
equivalent they are put together and placed in the liquid solder in the recess of the
copper bit, the solder immediately covers the parts treated with the solution, and
firmly solders them together the recess in the copper bit is of such size and shape
as to hold sufficient solder to make six or more joints, each time the bit is heated,
the remaining solder is allowed to run into the hollow receptacle before named
until the bit is reheated, by such means I am enabled to solder together the ends
of telegraph or telephone wires or other metal terminals in considerably less time,
and with less waste of solder than heretofore.

I make a frame of four "legs" connected at the top by cross pieces, the top being
covered with cane, similar to the seat of an ordinary cane chair. A short distance
from the feet of these "legs" there is another crossframe, on which I place a plate
of iron, fastened to which is a species of trivet, or circular or other shaped holdfast.
The plate of iron is fastened to the middle frame by movable bolts working in slots
in the plate, or by other suitable means. Into the trivet I drop a pan of iron
covered with a lid. This pan can either be filled with hot embers or with a piece
of iron made to fit it, and heated for the purpose and is covered with the lid to
prevent any sparks escaping. On each side of the top part of the frame I attach
another frame, also covered with cane, and having movable legs, so that these two
sides can be raised on the movable legs, and so form a sort of roof, over which the
bedclothes or other articles to be dried are placed, quite away from any danger of
fire. I would have it understood that I do not confine myself to the use of cane in
covering the apparatus, nor to the use of iron particularly in the parts made of
metal, but I use any suitable material for either purpose.
I can also, by covering in the sides and bottom of the apparatus, use it as a box
or trunk for travelling, when it can be utilised for carrying clothing or other effects
unless when wanted as a dryer or airer.

This invention relates to an improved method of producing photo-lithographic
plates for use in printing.
The object of this invention is to produce a plate from which a picture or the
like can be printed the shades of which are formed by a number of points or dots
placed more or less close together, the design for the picture being engraved upon
a zinc or other plate, from which impressions may be taken by pressure. The
production of the design is accomplished by taking by photography from a negative,
a small representation of the object which is to be reproduced. This representation
is enlarged whereby a design is produced which consists of a great number of
small points or dots and which is thus in a suitable form to be engraved upon a
zine or other plate in order to be reproduced by pressure. To prepare such a
design it is necessary that the collodion employed for taking the representation
should be very thin and only slightly iodized, as upon this depends the size of,
and the distance between, the points or dots. The plate should have a coarse or
a fine grain according as a greater or lesser enlargement of the proof is required..
The liquid, the composition of which is given below, is that which is required
for the production of the small image.

when the solution is stronger, and darker when the said solution is weaker; the
design can be transferred upon the stone in the ordinary manner and the picture
or the like can be reproduced by lithography.

IMPROVEMENTS
AUTOMATIC CHECKING OR STOPPING DEVICES OR APPARATUS FOR USE ON
IN
RAILWAYS
>>
The object of this invention is to enable the signal man to shut off the steam and
apply the brakes if desired. A movable rail or equivalent of any required length
is placed at the required position beside the ordinary rail; its ends are preferably
curved downwards and it can be raised or lowered by the ordinary connections if
preferred from the signal box or otherwise by eccentrics, levers or in other
convenient manner.
A rod terminating in a pulley depends from the engine or in some cases where
it was required to apply the brakes only it might be fixed upon one of the
coaches &c-and kept down by a spring or weight and its other end carries an
insulated plate which when the rod is raised makes contact with two other plates
so as to enable an electric current to pass as will presently appear.
Upon a convenient axle of the engine or vehicle is fixed an electro magnet and a
suitable armature depends from a slide above it so that it can rise or fall as desired.
The armature is connected in any suitable manner, as by a chain or rod with
preferably an independent valve which can shut off the steam from the cylinders
and where the brakes require it the steam may be at the same time turned on to
them or to an injector &c. Where air pressure is used as in the Westinghouse
brake the air valve may be opened.
When the movable rail is raised the pulley mounts upon it as the engine passes;
this raises the rod and the switch plate makes contact and the current passes to
the electro-magnet which attracts the armature and closes the valve and so shuts of
the steam from the cylinders and also applies the brakes, if so arranged, as already
explained. When the rail is lowered the rod descends and the valve opening steam
is again admitted to the cylinders
The electro magnet in revolving draws the armature round with it as far as it
can go and thus exerts a powerful pull upon the valve; when the direction of

page_text: revolution of the magnet is reversed the armature rises up in its slide and comes
down again on the opposite side of the magnet, so that the pull is exerted
which ever way the magnet revolves. Suitable means are provided for returning
the steam and brake valves when the switch rod lowers again. The current is
provided in any convenient manner as by storage or other batteries or a dynamo
upon the engine or vehicle
In some cases the current may be dispensed with and the side rod be caused to
actuate the valve or valves by suitable connections.

AUGUST EGESTORFF of the Borough of Kingston upon Hull in the County of
York. "IMPROVEMENTS IN MEANS FOR PRESERVING AND HARDENING WOOD, AND
RENDERING THE SAME CAPABLE OF RESISTING WEAR AND PRESSURE AND
IMPERVIOUS TO WET, DAMP DECAY, ROT, FIRE, OR OTHER INTERNAL OR EXTERNAL
DESTRUCTION OR INJURY."
The object of my invention is to effect improvements in means for preserving
and hardening wood, and rendering the same capable of resisting wear and
pressure, and impervious to wet, damp, decay rot, fire or other internal or external
destruction or injury.
The means whereby I effect these improvements is by applying to the wood
operated upon certain ingredients consisting of alkalies and phosphates varied by
use of Urine and Salts which are caused to impregnate and permeate into, through,
and among the pores and fibres of the wood.
The wood is cut and arranged in any form which is most convenient for the
purpose to which it is to be applied and is then boiled in a mixture consisting of-
quantities
Water
Urine
100 pounds
20 pounds.
5 pounds.
Burnt and unslaked Lime
and Creosote Tar in or about the same proportions for other
I sometimes use burnt and unslaked lime mixed with salt and water to a strength
of 20 degrees in the proportions of
Water
Lime
I sometimes use water
Burnt Lime
Phosphate of Soda
5 pounds
100 pounds
100 pounds
5 pounds.
The boiling is continued as long as is necessary in order that the wood may
become thoroughly saturated, and requires 20 hours in open boilers.

page_text: Sometimes I boil the wood. with the ingredients under reduced atmospheric
pressure for Six hours instead of in open boilers.
The proportions of the mixture as well as the time required for boiling varies
according to the dimensions and character of the wood and the degree of hardness
and nature of the fibre.
After sufficient saturation and permeation the wood is allowed to cool in the
liquid and afterwards dried in the open air and when dry is ready for use.

"
WALTER AYRES of 305 Kingsland Road in the County of Middlesex, Iron-
founder, IMPROVEMENTS IN THE MANUFACTURE OF SASH WEIGHTS AND OTHER
ARTICLES"
This Invention relates to certain improvements in the manufacture of sash
weights and other articles, the object being to so make the articles that they will
be of superior finish and that they may be supplied at a cheaper rate than
heretofore.
The Invention is carried out as follows:-I make a chill with a recess on each
side, and insert therein a transverse core of cast iron or other metal, provided with
projections to take into the recesses in the chill (to prevent the metal running in
front or behind the core, thereby enabling said transverse core to be easily removed,
after the casting has been effected) and I then insert perpendicularly through the
chill a tapered core, the upper end of which perpendicular tapered core takes into
a recess in the transverse core, and thus will be formed the holes in the casting for
the reception of the sash line or suspending cord or wire when the weights or
articles are used for other purposes.

OF SERRATED WEDGES."
Our Invention relates to an Improved Wedge suitable for wedging adjusting
and packing purposes. The said wedge is cast in metal with one or both sides
serrated in such a manner that the same may be easily driven forward but not
readily withdrawn, two wedges thus constructed may be driven one over the
other and act as a folding wedge. Our Invention further relates to an Improved
means or apparatus for shaping or cutting serrated surfaces on wooden wedges for
the purposes aforesaid, and consists of a series of cutters placed and secured upon
a revolving shaft or spindle. The wood is first sewn up into long strips and
passed under the cutters which cuts or flutes the strips longitudinally. The strips
thus fluted or serrated are afterwards sewn or cut into lengths to the breadth of
the wedges required.

ALFRED JULIUS BOULT of the Agency for Foreign Patent Solicitors, 323 High
Holborn in the County of Middlesex, Engineer "IMPROVEMENTS IN CALCULATING
APPARATUS," [a communication to him from abroad by Arnould Seignon a person
residing at Marseilles, Republic of France,]
This instrument consists of a suitable number (at least nine) of branches or
leaves, arranged like a fan, which on the top bear, one each of the first nino
numerals. Each leaf is divided into eight squares and each square contains one of
the first eight multiples of the figure which is marked on the top of the leaf each
multiple being again divided by a diagonal line which separates the tens from the
6 times 8 =
This therefore is simply the ordinary multiplication tablo, called the table of
Pythagoras, with this difference, that all the multiples marked in so many squares
aro decomposed into tens on the one hand and units on the other.
With this system the greatest multiplications can without the least difficulty be
carried out as well as all the operations that are directly derived therefrom.
This apparatus will have the shape of a fan but the principle of the invention
may be applied to other shapes also.
The material may also be any that is found convenient.
IMPROVED CONSTRUCTION OR ARRANGEMENT OF SECONDARY BATTERIES OR ACCUMULATORS

ISAC LOUIS PULVERMACHER of 194 Regent Street in the County of Middlesex
Electrician IMPROVED CONSTRUCTION OR ARRANGEMENT OF SECONDARY BATTERIES
OR ACCUMULATORS
This invention relates to certain methods of constructing secondary batteries for
storing electric energy in maximum quantity with minimum of weight and spaco
without being liable to derangement from ordinary handling
The appliance or secondary battery is easily and inexpensively constructed.
To carry my Invention into practice I spin lead-wire over a cord of thin metal
preferably composed of three distinct wires of different kinds vis a thin platinum
wire a copper wire and a lead wire as a compound core analagous to Gimp.
The lead wire which I spin upon this compound core is spun with its coils a
slight distance apart to form interstices for the reception of a paste of oxide of
load (red-lead).
I then take a strip of perforated, lead and spin or coat in spiral order the first
mentioned wire spun cord or gimp thereon to make a band of any desired width
and length which can be rolled up with an insulated material between each roll as
to form a somewhat rigid coil. The insulated material is perforated to permit of
the circulation of the electrolyte (liquid) through and between the coils and the
gases formed while charging to escape.
I purpose employing two of such coil coated strips as an element with insulating
material between them and to place any number of such elements of compact
construction one above another or superposed and these are connected either in
series or parallel.
The coil elements are arranged in a cylindrical vessel containing the electrolyte.
Instead of employing a perforated lead strip as the internal body of my spun
wire coated elements I may employ a perforated strip of insulating material such
as colluloid.
-
According to another construction or arrangement of secondary or storage
battery or elements for the purpose I cover the compound gimplike wire cord
with woollen thread with spacos between the wool winding or spinning the other

page_text: compound gimplike wire cord being uncovered. This with the woollen cover cord
are then wound upon the perforated insulating strip in spiral order and lodge
themselves side by sido thereon.
The woollen covered compound wire cord serves as the anode and the uncovered
compound cord the kathode the latter compound cord having the spaces between
the lead wire spinning filled with Letharge and those of the woollen covor
compound cord with peroxide of lead
Bands thus prepared can be rolled up with a perforated strip of insulated
material between the coils and placed in a vossol containing the electrolyte.
IMPROVEMENTS IN REVOLVING FIRE-ARMS

(Void by reason of the Patentee having neglected to file a Specification in
pursuance of the conditions of the Letters Patent.)
PROVISIONAL SPECIFICATION left by the said Walter William Colley at
the Office of the Commissioners of Patents on the 30th October 1883.
WALTER WILLIAM COLLEY of Camberwell in the County of Surrey, "IMPROVE-
MENTS IN REVOLVING FIRE ARMS,"
My Invention relates to an improved self cocking revolving gun for military or
sporting purposes, the gun being cocked, fired and revolved by one and the saine
means. The revolving cylinder containing any convenient number of charge
chambers turns upon a tubular axis, and is revolved by a pawl and ratchet motion
actuated by the hammer as in an ordinary revolving pistol. Through this revolving
axis passes a sliding rod which is jointed to the hammer at its rear end and at its
front end to a lever handle pivoted beneath the barrel of the gun in a suitable
position for being worked by the left hand whilst the gun is held up to the
shoulder in position for firing said lever acting at once as a means of supporting
the gun in that position and at the same time as a means of cocking and as a
trigger for firing the gun the ordinary trigger being dispensed with. The cocking
is effected through the medium of the sliding rod above mentioned whilst the firing
is effected through the agency of another sliding rod jointed to the said lever (at the
opposite side of its centre of oscillation to that at which the cocking rod is jointed.)
said rod working through a suitable guide and abutting against the end of a
corresponding rod in line therewith which is jointed to the scar. Thus by moving
the hand lever to and fro the hammer is cocked and the cylinder revolved by the
motion in one direction and the gun is fired by the motion in the other direction.

page_text: With the said hand-lever or with the sliding rod for cocking the hammer may be
combined a motion for extracting the spent cartridge cases if desired.
With this gun the whole of the charges may be fired in very rapid succession
without even taking the gun down from the shoulder.
In the case of sporting guns I may provide the ordinary trigger action for firing 5
the gun in lieu of handlover above mentioned if preferred.
IMPROVEMENTS IN BICYCLES
Year: 1883

page_text: PROVISIONAL SPECIFICATION left by John George Parker at the Office of
the Commissioners of Patents on the 1st December 1883.
JOHN GEORGE PARKER, Engineer, of Gracechurch Street, in the county of
Middlesex, "IMPROVEMENTS IN BICYCLES,"
My invention has for its object to reduce the power required for driving bicycles
and also their liability to accidents.
.
For this purpose I take two large wheels, preferably about seven feet in
diameter, and mount them loose on the ends of an axle curved forward or
backward in the centre, so as to give room for the body of the driver when
standing. On each side of the central opening I secure on the axle a support or
crutch of sufficient height and at a sufficient distance from the centre to reach
under the arm of the driver and to afford a rest for the same.
When using the bicycle the driver takes a standing position in the centre
between the two wheels, so that his centre of gravity is approximately in the same
vertical plane as the axis of the driving wheels. He places his arms on the said
crutches or supports and allows the weight of his body to rest on the same, while
the feet are alternately touching the ground and are only used for propelling the
vehicle. The axle may be made of two parts, and the central opening closed by
an adjustable strap or formed by a frame attached to the axles, instead of being
formed by the same. The crutches are preferably supported by springs in order to
counteract vibration.
