HANDEL BEECH of Denton in the County of Lancaster Machinist * IMPROVE-
MENTS IN SEWING MACHINES"
My invention relates first to the feed motion of sewing machines, and secondly
to the guide or folder, and the object of my improvements is to produce an angle
stitch by means of an improved feed motion placed at an angle with the arm of the
machine; the feed motion being secured above the table and driven either from the
top shaft or any convenient horizontal shaft above or below the table.
My improved "feed" consists of a frame secured to the bed or other convenient
part of the sewing machine; a bush is supported by the frame near the top, and
forms a bearing for the small shaft, which actuates the "feed."
To the top shaft of the sewing machine is secured a bevil wheel which gears
into and drives a bevil wheel fixed to the shaft for working the "feed"; at the
other end of this shaft is a disc with an eccentric pin which acts upon and imparts
a vibrating motion to the stitch lever, pivoted on a fulcrum in the frame; the
lower end of the stitch lever is. round and lies in a recess in the feed bar, to
which a to and fro motion is thus imparted: the feed bar slides in the lower part
of the frame.
The size of stitch may be regulated by an adjusting screw turned by hand,
which passes through the fulcrum stud of the stitch lever.
In place of driving the feed motion by bevil gears and an eccentric pin, acting
on the stitch lever, any suitable mechanism may be employed for imparting a to
and fro motion to the stitch lever from the top shaft or other horizontal shaft.
The second part of my invention consists of an improved guide for sewing
machines, when used for piping and binding.
This guide is formed of a piece of metal with the edges turned over, and the end
nearest the needle folded or doubled so as to fold the fabric, leather, or the like
over the cane, wire, cord, or other material.
Between this guide and the needle or needles I place a piece of metal or other
substance with a slot cut from the edge and terminating in a hole or eye; the
edges of the fabric or leather rest in the slot and the cane or wire covered by the
fabric or leather pass through the hole or eye which guides and presents them to
the needle or needles ready to be sewn together

HERBERT JOHN HADDAN, of Kensington, Middlesex, "IMPROVEMENTS IN
APPARATUS FOR BEATING SCYTHES," a communication to me from abroad by Jean
Faugère, of Montignac de Lauzun, France,
This invention relates to apparatus for beating scythes which apparatus comprises
chiefly the following parts. A piece of iron about 30 centimetres in length, the
upper end of which is cut obliquely and forms an anvil, while the lower end is
pointed so as to permit its insertion into the ground or into a block of wood. To
one side of this anvil is fixed a steel spring of the same breadth and reaching to
the same level as the anvil. To the other side of the anvil, and fixed by means of
the same screws as the steel spring, is a forked support made of brass or iron.
Each branch of this support is perforated at the end and adapted to receive a screw
spindle one end of which is slotted and serves to hold a small pulley made of brass
and also to receive the sharp side of the scythe.
The slotted end of the spindle is connected with the anvil by means of a helical
spring.

" IMPROVE-
MENTS IN AND IN APPARATUS FOR EMPTYING THE CONTENTS OF CENTRIFUGAL
MACHINES, AND IN SEPARATING LUMPS FROM FINER MATTER IN THE CENTRIFUGAL
MACHINE
33
In the use of a centrifugal machine much time and power are lost by having to
stop the machine, empty it, fill it again, and start it, getting it gradually up to
full speed. Now this invention is designed to save this loss and delay, and also to
enable me to separate lumps from finer particles in the centrifugal itself, while
running at full spred Upon the stationary framework of the centrifugal or other
stationary base, I fix an adjustable spout. This spout which has a chisel or gauge
shaped end, can be made to dip down into the centrifugal cage, with its edge
facing the way the machine is rotating. When the material in the cage is sufficiently
operated upon, this spout is guided against the mat-rial sticking on the side of the
cage. The immense speed at which this is rotating, forces the material to fly up
the spout into any receptacle outside the machine, into which the stream of material
may be directed. In this way a receptacle can be filled, the edge of the spout,
momentarily withdrawn from the material, an empty receptacle substituted for the
full one and filled in its turn. Canisters with spouts attached can, if desired, be
used, the spout being guided into place in the machine by stationary guides. The
spouts, if they be not required to guide the material into any special article, but
merely onto the floor, can be Hat like ordinary boards sharpened at the end.
In case it is wanted to separate sand from clay and pebbles, the clay is washed
out in the centrifugal with water, and a fork or skeleton scoop inserted, and the
pebble forked out on the above plan. An ordinary scoop can now be put in and the
sand extracted as above described. In this way lumps can be graded, by using
different meshed forks, and can be separated from coarse grains or powder, and
coarse grains can be separated from impalpable powder.

FOR COMBING AND PREPARING WOOL, COTTON AND OTHER FIBROUS MATERIALS
(A Communication to me by Charles Frederick Alexander, Wool Combing
Overlooker of Philadelphia in the United States of America)
The primary object of this invention is to dispeuse with the ordinary arrange-
ment of drawing off rollers and aprons of so called "Nobles" combing machine, to
produce a lighter noil and increase the capacity of the machine, and for this
purpose an arrangement of apparatus is employed by which a sufficient twist is put
in the slivers between the improved arrangement and the comb circles, preventing
thereby the fibres of the material being drawn apart.
For the above purpose of twisting, a revolving box is employed containing a pair
of rollers which are retained in contact with each other by means of springs or
their equivalents.
The sliver is passed between these rollers through suitable openings in the box.
The rollers in the interior of the box may be so geared as to perform the drawing
and twisting operation simultaneously or they may be used for twisting only and
caused to revolve by the movement of the sliver, in the latter case requiring
drawing forward rollers, motion being imparted to these from any convenient
source.
Suitable guides and shield plates are employed for retaining the sliver at the
correct height and position.
The above described arrangement for twisting is applicable to other classes of
combing and preparing machines for wool cotton or other fibrous materials.

IN STEAM BOILERS. [Communicated to him from abroad by Edouard Delpech, of
Marseilles, France]
رو
The object of this Invention is to avoid the loss of heat due to the accumulation
of soot in boiler tubes, the thorough cleaning of which is always a matter of
considerable difficulty and trouble.
According to this Invention in order to obviate these objections, the tubes or
flues of steam boilers are made of large dimensions varying from 1 foot to 3 feet
in diameter and are provided with metallic rods projecting on the inside and
outside of the tubes. In this manner the soot is prevented from adhering and the
heating surface is proportionately augmented.
This novel application of metallic rods to the tubes of steam boilers is based on
the property possessed by certain bodies of propagating heat when brought in
contact with other bodies, or in other words, upon the conductibility of metals.
The Invention is illustrated in the accompanying drawings as applied to a double
barrel boiler having double return flame tubes, although it may be employed in
connection with any other description of boiler.
Figure 1 is a front elevation of the boiler, Figure 2 is a cross section taken on
line A B Figure 1 showing the metallic rods or conductors radiating from the
tubes; Figure 3 is a longitudinal section on line C D E F; Figure 4 shows in plan
the manner in which the metallic rods X are disposed.
The rods may be made of any metal but preferably of copper which is an
excellent conductor and has a melting point as high as 1150° C about. The rods
being for one half of their length exposed to the heat and the other half immersed
in the water, are thus prevented from becoming red hot and destroyed by the
heat.
By the use of these metallic rods or conductors in the manner described a
reduction of fuel is ensured exceeding that obtained by any other system hitherto
employed.
IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR, SETTING THE TEETH OF CIRCULAR SAWS

WILLIAM ROBERT GODLONTON ROEBUCK of New Inn Yard, Shoreditch, in the
County of Middlesex, "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR,
SETTING THE TEETH OF CIRCULAR SAWS
11
The object of my said Invention is to provide a simple and efficient apparatus
for setting the teeth of circular saws to definite angles.
I construct an iron bed plate, of suitable length and width, having a dovetail
groove on or in its upper surface, cut longitudinally from end to end. I fit into
this groove a sliding pivot to receive and secure the centre of the circular saw, the
pivot being placed in such a position in the slot, that the teeth of the saw project
beyond the bed plate. The sliding and adjustment of the pivot is rendered
necessary in order to accommodate the radius of the saw, and to suit saws of various
diameters.
At one end of the bed plate I fix a steel bevel, the upper side of which is
bevelled off to the exact angle required for the teeth of the saw. This bevel piece
is carefully prepared, hardened, and tempered, and is firmly screwed to the end of
the bed plate, and crosses the end of the dovetail groove.
The sliding pivot is fitted with a dovetail and adjusting screw to fix it in any
part of the groove.
In the operation of setting the teeth of a circular saw, the centre is fitted to the .
pivot in such a position that the teeth lie directly over the bevel. Every alternate
tooth is then struck or pressed to such bevel, the saw being revolved until half the
teeth have been so treated. The saw is then placed on the bed plate the other
side upwards, and the remainder of the teeth are treated in the same manner. By
these means all the teeth of the saw will have a similar or equal "set"
or bevel
without any inequality on either side, and the resultant "clearance" will be
uniform on both sides of the saw when in use.

HENRY BARRON, of Kilburn, in the County of Middlesex, Sanitary Engineer,
"AN IMPROVED PERAMBULATING SANITARY TOILET AND ADVERTISEMENT CAR.'
"
My invention relates to a novel construction of perambulating car, designed to
afford means for sanitary or toilet purposes, easily available, and transportable
from place to place, and available as a novel and striking means for the display of
advertisements.
My car consists in the first place of any convenient form of body, mounted upon
suitable wheels, and roofed in. Along the centre of the body is a passage, and
from the walls to the passage extend partitions of wood or other suitable material,
thus forming a number of chambers on each side of the passage. These chambers
are separated from the passage by curtains or hinged doors, and they may be
partitioned of various sizes. The larger ones, preferably near the door, which is
at the rear of the car, form chambers for an attendant, waiting room, and for
toilet purposes, whilst the smaller ones, preferably more remote from the door, are
fitted with earth closets and disinfectant and deodorizing apparatuses (preferably of
the form patented to me in conjunction with Herbert Raimes 15th November 1881
Number 5003) applied thereto. The walls of the body have windows corresponding
to the chambers, and the blind of each of these windows is in the form of an endless
band stretched over two rollers, one above and one below the windows, reaching to
the end of the car, where either one or both is fitted with a cranked handle or
other convenient means of rotation. The endless blinds bear upon them various
advertisements, of the size of the windows, and a turn of the crank will bring
forward a fresh portion of blind to the window bearing a fresh advertisement, and
so on continuously through as many advertisements as the length of blind will
allow. The front of the car is fitted with shafts and a drivers seat external to the
body of the car, and the rear with suitable steps.
My thus specified car will be found of great service by its availability, whilst
slowly perambulating the streets of a city, and exhibiting the changing advertise-
ments (as also fixed external ones if required), or it may with ease and advantage
be readily transported to race and other open air meetings, such as exhibitions,
school feasts, etc.

Wilhelm Spaethe, of Gera, in the German Empire,
This invention relates to musical boxes, barrel-organs and other mechanical
musical instruments, in which pin-barrels or perforated sheets of paper are generally
used for producing the desired melody.
It consists in replacing the pin-barrels or perforated sheets by a sheet of metal
provided with elevated lines or dots produced by stamping or embossing and
corresponding as regards their length and distance from each other to the notes to
be played by the instrument.
Also in making the barrels of barrel organs or similar instruments from a sheet
or sheets of metal fixed on two discs mounted on a shaft, the said sheets being
provided with embossed or stamped elevations, and adapted to be easily exchanged
for playing another tune.
Also in making the distance of the barrel shaft from the keys adjustable by
providing each axle bearing with a vertical alot, and with a horizontally movable
slide, which has likewise a vertical alot with two or more superposed lateral
recesses, any of which may carry one end of the axle, the width of the vertical
slots and of the recesses being equal to the diameter of the axle. This arrangement
has for its object to adapt the bearings for barrels of different diameters.
IMPROVEMENTS IN THE MANUFACTURE OF ELECTRIC CONDUCTORS AND IN PLATES FOR GENERATING AND CONDUCTING ELECTRICITY

Commissioners of Patents on the 21st December 1883.
JOSEPH KAHN temporarily of the Bedford Head Hotel, Tottenham Court Road
in the County of Middlesex. "IMPROVEMENTS IN THE MANUFACTURE OF ELECTRIC
CONDUCTORS AND IN PLATES FOR GENERATING AND CONDUCTING ELECTRICITY."
The chief object of this invention is to effect an economy in the manufacture of
electric conductors.
The invention also applies to the manufacture of terminal earth plates and
positive and negative plates for primary and secondary galvanic batteries.
In manufacturing an electric conductor, I take a strand or a cord of spun
vegetable or other fibre and submit the same to the process of electro deposition,
whereby I obtain not merely a coating of the strand or cord but also a metallic
deposit within the body of the strand or cord.
When I require a conductor for carrying powerful currents I combine together
strands treated as above described and combine them into a cord or rope by
twisting. The cord or rope thus produced I submit to the electrotype process and
thus effect a metallic union between the strands.
The fibres I prefer to employ for the production of the strands are either cotton,
flax, wool or asbestos, the special merit of the latter being that it has no tendency
to decomposition or to become damaged by overheating. In general copper will
be the metal employed, but silver or other good conductors of electricity may be
used for coating the fibres. Electric conductors of this class may when thought
desirable be covered by silk or cotton or other insulating material such as Gutta
Percha or India Rubber, and they may be strengthened by the insertion therein
or by the addition thereto of wire.
In preparing terminal plates or electrodes I take a coarse woven fabric and
submit it to the electrotype process, whereby I produce at a cheap rate a metallic
cloth of any suitable character which may be cut up into plates of suitable size for
insertion in primary or secondary batteries. When used in primary batteries
comparatively small plates will, owing to their cellular or porous character present

page_text: a large surface to the exciting liquid, and similarly when applied to secondary
batteries the like beneficial result will be obtained. The fabric which I prefer to
employ is that known as asbestos cloth.
By the use of metallic plates of this character I effect material economy in the
manufacture of batteries and render them applicable in a variety of cases where
the ordinary heavy and bulky batteries would be inadmissible.

The principal feature of my tube-expander is that every roller bas a separate
casing which is hinged to a common ring by means of a link, so that during the
expansion of the rollers the casing rests always firmly against the ring, with a
point of its surface, like a wheel rolling on a fixed base. The roller casings are
further held together concentrically by means of an indiarubber ring.
The manipulation of the improved expander is like that of ordinary expanders,
a conical mandrel being introduced concentrically between the rollers and driven
home either by strokes of the hammer on its back or by means of an automatically
acting screw and nut.

radially from the body of the said benter.
In further carrying out this invention, I employ with the main card cylinder,
and the doffer and the anti-suction plate of the former placed between them, a
rotary beater arranged directly over the said plate and between the doffer and
main card cylinder.
This auxiliary rotary beater is to remove from the doffer, any extraneous

of Berlin in the German Empire,
The material employed in gas works for purifying the gas contains after having
been used, besides ammoniacal salts, tar, wood shavings, chiefly sulphur, oxide of
iron and ferro-cyanides.
In carrying out the present invention the soluble ammoniacal salts are extracted
from the spent purifying material by lixiviation, after which the residue is heated
in a closed vessel with an excess of lime and with water, to more than 100 degrees
centigrade, whereby calcium ferro cyanide and calcium sulphide are formed.
The latter product acts on the former, so as to produce calcium thiocyanate and
a sulphur compound of iron. Any sulphur which may have been absorbed by the
excess of lime is removed by the addition of sulphate of iron (green vitriol).
The solution of calcium thiocyanate thus obtained is purified in the usual
manner or converted into other thiocyanates.
Instead of lime, other bases, such as potash or soda, may be used.

direct upon the resonant part, it creates a vacuum (as in the injector) and, by
It consists

of an apparatus containing a nozzle through which the steam issues and by suction
draws the atmospheric air through an instrument tongued in a manner similar to
In order to

increase the sound the instrument is preferably enclosed in a funnel shaped casing
with a trumpet mouth to convey the air to it. A number of instruments may be
fitted with tongues each of which, as the air is drawn through it, may be so
proportioned as to emit a different note tuned so as to produce a kind of harmony.
The group of instruments is enclosed in a casing into which the air is drawn, by
the steam blast, through an opening so as to operate in succession on each
instrument and produce a continuous series of notes. A simple method of effecting
this is by making the cover of the casing, with one aperture for the entrance of
the air, to revolve on a central spindle so that the air in rushing in (impinging
upon an inclined wing or vane) will cause it to revolve and thus to convey the air
in succession to each instrument. Or by simple mechanism the action of the air
upon the instruments may be controlled by hand so as to sound any one note
continuously or a succession of different notes. Thus an intelligible code of signals
may be established which will be of great service in steam ships at night or in
foggy weather.
Such signals at fixed stations may be arranged to indicate their position to ships
at sea on a coast as a lighthouse is recognised by the character of the light
exhibited and are besides available for many other purposes.

method the brush is fixed upon an axle carried in a bearing or bearings at one end
of the rod or polo and provided with a grooved pulley around which is passed a
cord or belt. This cord or belt is also passed around another pulley carried by a
pin or stud fixed in the other end of the said rod or pole. According to another
method the said axle is provided with a crank in place of the pulley, which crank
is arranged to be rotated by means of a cord, wire or the like extending to near
the other end of the said rod or pole.
The said rod or pole is sometimes made telescopic or in lengths joined together
in any suitable manner. And in some cases I make a number of circular or
cylindrical brushes of different lengths or having bristles more or less flexible, so
that either of them can be placed upon the said axle, according to the shape or
nature, of the part to be cleansed or dusted.
It will be obvious, however, that the construction of the apparatus and the mode
of rotating the brush may be somewhat varied, if desired, the chief feature of tho
invention being the construction and arrangement of the brush in such a manner
that it may be used for cleansing places which would be out of reach with an
ordinary hand brush.

EDWIN JOSEPH SMITH of Grays Inn Road in the County of Middlesex,
"IMPROVEMENTS IN LOCKS OR FASTENINGS,"
The improvements consist in the combination in one lock or locking device or
lockcase of a slam bolt and a push bolt in such manner that the slam bolt being
operated the push bolt is operated by it. The invention is performed by making
the lock-case or box with two faces one at right angles to the other; through one
face the slam bolt projects and through the other the push bolt, both being worked
by the same pivoted tumbler-or other mechanism may be employed. The object
of the invention is to dispense with flush or thumb push bolts.
IMPROVEMENTS IN VICES AND CHUCKS FOR HOLDING WORK

Commissioners of Patents on the 12th October 1883.
JOSHUA HEAP of Ashton-under-Lyne in the County of Lancaster, Machine Tool
Maker, "IMPROVEMENTS IN VICES AND CHUCKS FOR HOLDING WORK
"
My Invention relates more particularly to the vices and chucks which are
employed to hold work or metal parts whilst being operated upon by machine tools
but may also be applied in part in the construction of bench vices. In the first
place I construct vices and chucks with jaws which can be set out of the parallel
so as to grasp work of taper or irregular formation. The jaw is provided with
a gripping piece which is turned to a convex curve and beds against a concave
seating turned in the front of the jaw. A facing on the back of the jaw is turned
or formed to a curve which is concentric with the front curve. A shank on the
gripping piece passes through a slot in the jaw and is provided with a nut whereby
the gripping piece can be fastened in position when adjusted to the work. In a
chuck and in some forms of vices the jaws are brought together by means of a
right and left hand screw. In cases where one jaw is fixed I prefer to employ a
left band screw and an adjustable tail pin as I can thereby dispense with the
ordinary loose collar. To shield the screw from cuttings I fix a shield over the
screw and form a slot in the jaw or a space between the jaw and the nut to clear
the shield.
In the second place I employ a revolving screwed ring to set up the dogs of a
chuck. The said ring is formed with a conical surface which when the ring is
screwed into a recess in the chuck forces the dogs towards the centre with a
simultaneous and equal movement of all the dogs.
IMPROVEMENTS IN MEANS FOR LOCKING NUTS UPON THEIR SCREW BOLTS

GEORGE AGARS WALKER commonly called John George Agars Walker of Danes
Hill near Retford in the County of Nottingham IMPROVEMENTS IN MEANS FOR
LOCKING NUTS UPON THEIR SCREW BOLTS
"
The Invention has for its object improvements in means for locking nuts upon
their screw bolts.
For this purpose I cut a longitudinal groove in the bolt across the threads of the
screwed part thereof and I use in connection with such screw bolt a nut of the
ordinary kind.
When the nut has been screwed up to the required extent I by means of a
punch force a small portion of the nut into the groove cut into the bolt by which
means the nut is fixed in position and cannot become loose from vibration.
AN IMPROVED STEAM SMOOTHING-IRON FOR LAUNDRY PURPOSES
Year: 1883

page_text: PROVISIONAL SPECIFICATION left by John MoLean at the Office of the
Commissioners of Patents on the 6th March 1883.
JOHN MOLEAN, of Belfast, in the County of Antrim, Ireland, "AN IMPROVED
STEAM SMOOTHING-IRON FOR LAUNDRY PURPOSES."
The object of my Invention is to improve the means or method whereby linen,
or articles of wearing apparel may be smoothened and a gloss produced in an easy
and efficient manner, and is accomplished chiefly by the application of steam for
the end in view.
For this purpose I arrange a suitable pipe over the bench on which the ironing
process is carried on, which pipe communicates with a steam-boiler; and to the
end of this pipe I connect one end of a flexible tube, the other end of which is
attached to the smoothing-iron, so that steam will enter the chamber provided in
the iron, through which it (steam) passes on to a second flexible tube, attached to
the opposite end of the iron, which conveys the steam to a heating chamber where
it is utilized for drying purposes. The steam in thus passing through the smoothing-
iron causes it to be kept at an equitable temperature for any given time; and the
temperature of the steam used may be varied at pleasure according to the class of
goods to be ironed.
By the application of steam in this manner, I claim the advantages of simplicity,
economy, and the production of better results than have hitherto been attained so
far as I am aware.

"IMPROVEMENTS IN FELTED
FABRICS AND IN APPARATUS EMPLOYED IN THE MANUFACTURE OF THE SAME
"
The object of my invention is to manufacture Felted Fabrics, with plain, or
fancy borders, or stripes, of a different color, or shade, to the other portion of the
felted piece, the borders, or stripes, forming part of the fabric itself, and are not
printed, or embossed upon it, such borders or stripes, may go through the felted
fabric, or only part through as required. Upon the feeder sheet of the scibbling
or carding machine I place narrow troughs, or partitions, forming spaces of sufficient
number, and at such distances apart as I require.
To form the borders, or stripes, material of different shades, or colors, to that of
the piece, is supplied to the troughs, or spaces, either in its raw state, or in the
form of sliver, condensed stubbling, yarn, thread, or weft, it being assisted forward
by a speeded roller; by the above means, uniform stripes of different colors or
sbades, are produced upon the felted fabrics, in any desired quantity or at any
distance apart, the color and width of stripes, or borders, may be varied to suit the
customers,
IMPROVEMENTS IN PUMPS, FOR EXTINGUISHING FIRE, AND OTHER PURPOSES
Year: 1883

Office of the Commissioners of Patents on the 17th April 1883.
EDWARD JOHN COWLING WELCH of Palace Chambers, St Stephens, Westminster
Civil Engineer "IMPROVEMENTS IN PUMPS, FOR EXTINGUISHING FIRE, AND
OTHER PURPOSES."
My Invention refers more particularly to that class of Pumps known as hand
pumps, such as are used by Fire brigades for extinguishing small fires but which
are also applicable to other purposes. I do not however limit myself to this
Application of the invention which consists of a general arrangement of parts
whereby a simple and yet double acting pump is obtained, without necessarily
involving the use of more Valves or more packings than are at present contained
in an ordinary single acting pump, and at the same time giving an increased
discharge of water without materially altering the size of the pump.
To carry this into effect I construct a Pump on what is known as the bucket
and plunger principle making the area of the bucket piston of double (or other
proportion of the area of the plunger or rain. The annulus thus formed however
being in most cases too narrow to allow of the valve or valves being placed there.
I place the upper or delivery valve in the centre of the bucket piston, practically
inside the ram, and just above this piston I form an outlet or outlets through the
sides of the ram which lead into the valve chamber so that the water can escape
into the annular space between the ram and the cylinder. The ram itself I make
hollow, leaving it open at the lower end where it unites with the piston, and
closing it at the top; by which I form the air vessel inside the plunger or ram,
thus avoiding the necessity of providing a separate one which would materially
increase the total size of the pump. The foot or suction valve is placed in a chamber
beneath the pump cylinder and both this and the delivery valve can be readily got
at when necessary without withdrawing the piston The only packings necessary
therefore are that for the bucket piston, and that for the gland at the top, through
which the ram or Plunger passes.
IMPROVEMENTS IN PEN AND PENCIL CASES

SIEGFRIED DUNKELSBÜHLER of Nuremburg in the Kingdom of Bavaria Manu-
facturer "IMPROVEMENTS IN PEN AND PENCIL CASES "
The object of my Invention is to construct pen and pencil cases for the pocket,
or for attachment to the watch chain or belt, in such a manner that the closing or
withdrawing of the pen or pencil into the case takes place instantaneously, and
thereby a saving of time and trouble is effected in such operation.
The ordinary ever pointed pencil, or common pencil holder, or pen holder which
slides into the tube (hereinafter called the "holder" is provided with a thumb nail
catch or pin, which projects through a slot in the side of the outer tube. This slot
is made sufficiently long to allow the holder to be propelled outwards and also to
recede into the outer tubo to protect its point.
At the inner end of the holder a trigger or catch is provided, attached to a
spring, which presses the trigger outwards.
When the holder is propelled outwards, for use, the trigger projects through a
second and shorter slot in the outer tube, and in that position keeps the holder
from receding again into the tube.
One ond of a spiral spring is attached to the inner end of the holder, and the
other end of such spring is attached to the back end of the tube inside. When the
holder is projected outwards for uso, this spring is in a state of tension, and its
tendency is to draw the holdor back again inwards; but it is prevented from
so doing by the trigger which catches in its slot and thereby keeps the holder in
position before use.
When it is desired to shut up or withdraw the holder into the tube, the thumb or
finger is used to depress the trigger, which causes it to leave its slot thereupon
the spiral spring instantaneously acts upon and withdraws the holder and its pen
or pencil into the tube, and the case is then ready for the pocket, or other place or
position in which it is desired to keep it,
IMPROVEMENTS IN BICYCLE AND TRICYCLE SADDLES.

FREDERICK WARRENDER SMALL of Walsall in the County of Stafford, Brown
Saddler IMPROVEMENTS IN BICYCLE AND TRICYCLE SADDLES.
This Invention consists of a metal support attached to the spring of the Bicycle
or Tricycle, the back of which support is forked, and to this forked end is hinged
another forked bar. This bar acts as a support to a thin metal plate which
supports the leather saddle, which is rivetted to it. This plate is hollowed out from
under the flaps or sides of the saddle. Between the two forked bars a metal spring
is placed, or this spring may be of India rubber or other suitable elastic material.
The bar carrying the metal plate is hinged or jointed so as to give greater
flexibility to the front of the saddle and relieve the rider from the effects usually
caused by jolting. The front ends of the forked bars may be jointed together.
