Improvements in Apparatus for Working Disappearing Targets for
Rifle Shooting.
I JOHN JAMES WOOD of Church House, Ardington near Wantage in the County
of Berks Estate Clerk of Works, do hereby declare the nature of this invention to
be as follows :—
My invention has for its object to provide a simple and efficient apparatus which
will easily and quickly raise from a pit or trench targets to be shot at and dummy
targets for signalling the value of each shot and for easily and quickly lowering the
said targets or dummy targets into the pit again.
The apparatus consists of a main beam having boxes or bearings in the centre of
its length and revolving in a slightly inclined vertical plane-similar to the wind-
sails of a windmill-on an axle which said axle is secured to a post or other support.
At the ends of the revolving beam I form sockets for receiving the wooden legs of
the targets and dummies.
The said targets or dummies being securely held in the sockets by means of
screws and swivelled plates, one target or dummy being presented above the beam
and the other below it.
When the apparatus is worked the beam is caused to revolve on the axle carrying
with it also the targets or dummies and presenting one above the pit in a vertical
position towards the firing point and presenting the other in a reversed vertical
position towards the marker in the pit and being there held in position by means of
a trigger catch.

1 JOHN JAMES WOOD, of Church House, Ardington, near Wantage, in the
County of Berks, Estate Clerk of Works, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention has for its object to provide a simple and efficient apparatus for
working disappearing targets for rifle shooting which will easily and quickly raise
from a pit targets to be shot at and dummy targets for signalling the value of each
hit, and for easily and quickly lowering the said targets or dummy targets into the
pit again, which can be fixed and operated with little labour; to which targets of
varying sizes can be readily secured; whereby the targets used impart to each other
additional strength at their weakest points; and whereby the apparatus easily
holds the targets in position for shooting, or releases the hold for transposing
them.
The apparatus consists of a main beam, having boxes or bearings in the centre
of its length, revolving on an axle, similar to the windsails of a windmill. The
said axle is secured to a strong post fixed into the ground, or to a beam, trestle, or
other support.
Towards the ends of the revolving beam are fixed strong sockets provided with
set screws and swivelled plates.
These sockets, being open, allow the legs of two targets to be passed through

I, JOSEPH ERNEST BEAL of Redhill Works, Sheffield, in the County of York,
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 has for its object to more firmly secure, and to effectually prevent
the handles of table knives and the like, from turning round upon their tangs.
The invention is illustrated in the sheet of drawings annexed to this Specification
in which
Fig. 1, represents the side and back view of a table blade with the tang made
according to my invention.
Fig. 2, shows the handle for same, being the side, back and end views.
Fig. 3, shows a modification in the arrangement.
Similar letters of reference indicate similar parts in any of the figures in which
they may occur.
In carrying my invention into effect, in the manufacture of an ordinary table
knife for example, such as shown in the drawings, I form directly underneath the
bolster A, a projecting piece of metal B, extending from one side of the bolster to
the other, that is, as shown in Fig. 1, from back to front, and I prefer that this
projection shall be of the same thickness as the tang or thereabouts.
I make the handle shown in Fig. 2, to correspond, by cutting or otherwise forming
a groove or recess C, across the top edge, passing through the hole D, for the tang,
and into which the projection will fit when the parts are put together.
By these simple means the strength of the knife is greatly increased at the place
where it is usually the weakest, and the blade is effectually prevented from turning
round upon its tang.
As a modification I may vary the plan of construction as shown in Fig. 3, in
which the projection instead of being made in a line from the back to the front, or
edge, is made transversely or from side to side, the handle being grooved to
correspond.
I
may if desirable make the projection on one side only of the tang, and I do not
confine myself to the flat and squared form of the projection, as it may be varied in
its configuration to suit a recess in the handle formed by a revolving cutter.
Having now particularly described and ascertained the nature of my said
invention and the manner in which it may be carried into practice, I declare that
what I claim is :-
The improvements in table cutlery and similar cutlery, consisting of a single or
double sided projection B, directly under the bolster A, extending either from back
to front as in Fig. 1, or from side to side as in Fig. 3, and fitting into a corresponding
groove across the top of the handle, substantially as hereinbefore described and
show

Sizing Composition for Cotton Yarn.
I, JAMBETJEE EDULJEE BOYCE of Bombay, India, Merchant, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My said invention relates to a new composition to be used as an ingredient of the
mixtures used in sizing cotton yarns proparatory to their manufacture into cloth.
The purpose of such new composition which I designate "Boyce's Palm Composi-
tion for Sizing," as an ingredient of the size is to obtain a good "glaze" and
finish on the cloth and a very smooth "feel" when the cloth is handled.
Two of the ingredients of the said new composition, viz. :-Satvaina powder
and Jatamanasi juice are Indian vegetable products obtained from the Satavina and
the Jatamanasi plants.
The Satavina plant is known by botanists under the designation of Alstonia
Scholaris and is one of the Apocynaceae.
The Jatamanasi plant is known by botanists under the name of Nardostachys
Jatamanasi and is one of the Valerianaceœ.
The bark of the former is dried and pulverised. In the case of the Jatamanasi
plant small punctures or cuts are made in the stem and the juice which exudes
therefrom is used.
To as one hundredweight 119 the I of th
LL
The castor oil and the wax are mixed and then heated to boiling point at the
same time being continually stirred.
When the boiling point has been reached the Russian tallow is added and then
while still stirring the Satavina bark powder and the Jatamanasi juice are added
and thoroughly incorporated into the mixture which is then allowed to cool.
When cooled to the temperature of the atmosphere the palm oil is added and
thoroughly stirred and worked into the mixture.
The resulting composition is used as a substitute for and is added in the same
proportion as plain tallow to the other ingredients used in the preparation of size
for cotton yarn and the quantity to be used will vary according to the effect to
be obtained as is well understood.
The proportions and the order of adding the ingredients as given above are
merely stated by way of example and such as I find most convenient and suitable
for the purpose but they may be varied.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. As a substitute for plain tallow in the preparation of size for cotton yarn the
composition onbatantially haveinkafans deannibaldi kul

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 valves particularly applicable for musical instruments
the closure of which valves are effected pneumatically by suction or pressure upon
bands of air-proof material and such valves are opened by loosening and pushing
back the band or bands into folds all as hereafter described.
My invention will be understood by the following description referring to the
accompanying drawing on which Figure 1 shows a valve so constructed, the same
being closed, Figure 2 a similar valve opened, and Figure 3 is a horizontal section
through Figure 1.
The
According to my invention I provide in a valve chamber a Figure 1 one or more
bands or leaves of india rubber, leather, parchment or other airproof or suitable
material each band or leaf being fastened at one end to the bottom of the
chamber a and at the other end to a piece of metal or other suitable material c, so
that upon the lifting of the said piece o the bands & lie against or nearly parallel
and adjacent to the walls of the chamber a and cover the openings e, e¹.
hermetic closure of the openings ensues, upon the air suction taking place, through
one or more of the bands coming against the aperture or apertures e, e¹ and upon
the entry of air pressure the valve is closed by the pressure of the bands against
the walls of the valve chamber. The opening of the valve is effected by lowering the
piece c, by means of wire or rod d, actuated by, for example, a lever or a key
sliding downwards say by its own weight or by spring pressure or by depression of a
key or of a lever, and thereby drawing away the bands from the valve openings e
and e', so that the suction or pressure can freely take effect and reach the notes
(see Figure 2 in which represents the note for suction, 9 the note for compression
and e' the opening for the entrance and exit of the air).
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 single or double acting pneumatic valves for musical instruments the bands
or leaves composed of india rubber, leather, parchment or other suitable air-proof
material such bands or leaves closing the valves aperture or apertures either by
suction or by pressure the valves being opened by the drawing away or folding
down of the said bands substantially as described.
2. The general combination and arrangement of the parts composing my improve-
ments in single or double acting pneumatic valves all substantially as herein
described and illustrated with reference to the accompanying drawings.

of this invention and in what manner the same is: to be performed, to be
particularly described and ascertained in and by the following statement :-
My invention relates to the spring or holder used for steadying and holding the
whip when placed in the socket. At the present time this is done by a rubber washer
or ring, or by springs inside the socket, and my improvements consist in arranging a
spring near the top of the socket and making it from a covered or uncovered rubber
thread, or from an ordinary coiled metal spring which may also be covered.
In Figs. 1 & 2 I have shown my invention as applied to a wooden socket a having a
number of holes near the top edge for the rubber thread or coiled spring b which is
threaded in the manner shown and its ends secured by any convenient method. The
socket is recessed at c to hold the rubber or spring and at dito allow the same to

Improvements in Drawers for Cabinets and the like.
EYRE CROWE, Manufacturer, Gatteridge Street, Banbury, Oxon, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My improvements relate to drawers for cabinets & the like, more particularly to
those intended to hold papers, music etc. & their object is to facilitate the handling
or removal of the contents of the drawers.
In my improved drawers the fronts are attached rigidly to the remainder of the
drawer but are secured to brackets which turn on pivots fixed to the sides of the
drawers, so that when the drawer is opened the front can swing underneath
the bottom of the drawer leaving the drawer open at the front and the contents
easy to get at.
I will now proceed with the aid of the accompanying drawing to fully explain the
manner in which I carry out the invention.
The drawing shews the part section of a cabinet A with three drawers B, C & D
the top drawer being shewn open and the lower ones shut.
The fronts E. E have fixed firmly to each extremity a bracket F the other end
of which works on a pivot or pen G fixed into the sides of the drawer. The bottom
of the drawer may be cut back as shewn so that the papers or whatever may be in
the drawers will project beyond the bottom enabling the contents to be easily
handled.
The sides of the drawers are brought forward to form a stop for the front when
lifted up into the position for closing the drawer.
Having now fully explained the nature of my invention & the manner in which
it may be carried out, what I claim as novel in drawers for cabinets and the
like is
A drawer the front of which is made of a single flat piece & is connected to the
body of the drawer by means of two swinging brackets substantially as hereinbefore
described and illustrated.

An Improvement in Standard Electrical Condensers.
I, ALEXANDER MUIRHEAD, of Cowley Street, in the City of Westminster,
Doctor of Science, Electrical 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 :-
This invention has for its object the diminution of the variation of capacity with
temperature of standard electrical condensers and is based on the fact that it is
possible to build up a condenser of two different dielectrics which alter in inductive
capacity with temperature in contrary directions. I have found, for instance, that
the capacity of condenser plates having paraffined mica sheets as the dielectric
diminish with rise of temperature whereas that of condenser plates having shellacked
mica sheets as the dielectric increase in capacity with rise of temperature.
In the construction of standard condensers according to this invention I build up
the capacity required by combining a certain number of plates laid, in the manner
well known in the manufacture of electrical condenser plates, with shellacked mica
(or other dielectric whose inductive capacity varies with temperature in the same
direction) with the requisite number of plates laid with paraffined mica (or other
dielectric whose inductive capacity varies with temperature in the same direction)
to neutralize the effect of temperature upon the capacity of the former plates thus
producing a combination whose capacity is less variable with temperature than has
been obtained hitherto.
For example, supposing a standard condenser of one microfarad capacity is
required and the temperature coefficient of the shellacked mica plates is found to
be, say, '075 per cent. per degree centigrade, and that of the paraffined mica
plates to be, say, 025 per cent. per degree centigrade, then, according to this
invention, the capacity of one microfarad is made up of one part of shellacked mica
plates and three parts of plates of paraffined mica.
-
In the manufacture of such condensers I prefer to coat the whole surface of the
mica sheets with the paraffin wax or shellac.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In the manufacture of standard electrical condensers the employment of two
dielectrics the inductive capacities of which vary in contrary directions with
temperature substantially as and for the purpose herein set forth.
2. The combination in the manufacture of standard electrical condensers of plates
in which shellacked mica is the dielectric with plates of paraffined mica as dielectric
in such proportion as to reduce the variation of the capacity of the total with
temperature to a minimum substantially as herein set forth.

Improvements in Keys.
STER
I, PAREN ENGLAND, of 300, E. Hopkin Avenue, Aspen, Pitkin, County
Colorado, United States of America, Lawyer, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :—
My invention relates to improvements in that class of door locking keys which
are provided with an attachment in the form of a supplemental bit pivoted to the
key shank for the purpose of serving as a guard for the key hole.
Reference is to be had to the accompanying drawing, forming part of this
Specification in which similar letters of reference indicate corresponding parts in all
the figures.
Figure 1 is a sectional view of a portion of a lock with my improved key in
position;
Figure 2 is a perspective view of the key; and
Figure 3 is a longitudinal section thereof.
In the accompanying drawing, A indicates the lock, and a a' the oppositely-
disposed key-holes. B denotes the key, which is most clearly shown in Figures 2
and 3 of the drawings, by reference to which it will be seen that the same in general
appearance is of the ordinary shape, the body portion or stem being however apertured
longitudinally from its foot part to the finger member b¹.
In this longitudinal aperture B', is disposed a stem C, the lower end of which
extends slightly beyond the foot part of the key and is provided with a right-
angled locking finger or bit e, which is of the same thickness as the key foot b³,
proper and extends out flush with the same as shown.
The upper or outer end of the shank C is formed with a flattened head C¹, which
seats in the looped portion 3, of the key, as shown.
By reference to Figure 1 of the drawings, the manner in which my improved key
operates will be clearly understood. It will be seen that when the key is inserted
through the key-hole a, the locking finger e will enter the hole a¹ and plug the
same up, and as the key B is turned its foot part will be at an angle to the finger c
(see dotted lines, Figure 1), thereby preventing any possibility of the key being
pushed from the lock.
The key is simple, cheap, easily made, durable and makes an absolute lock for
the purpose intended.
I am aware that it is not broadly new to make a key with a pivoted locking
member which will serve to plug up the outer key-hole. I therefore do not broadly
claim such construction.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
The combination, with the key proper, having the bit 6, and hollow shank B,
rigidly connected, of the key-hole guard composed of the part c, the shank C, and
the flat head C', as shown and described.

Improvements in Planofortes and similar Instruments.
I HANS CLEMENS PETERS of Markt 2, Leipzig, German Empire, 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-
In teaching young children to play on the pianoforte, harmonium or other
keyboard instrument much difficulty is experienced as the said instruments have
their keyboard fixed at an invariable level, suitable for an adult but quite
unsuitable for a child. For the same reason different performers are unable with
equal comfort to play on any given instrument.
Now the object of the present invention is to provide means whereby the level
of a keyboard instrument such as say a pianoforte can be raised or lowered to
meet the requirements of players of different statue.
The said invention is illustrated in the accompanying drawings in which Fig. 1
is a front elevation and Fig. 2 an end elevation of a pianoforte to which this
invention is applied. Fig. 3 is a detail view on an enlarged scale.
It will be seen that in general construction the instrument does not differ from
those in common use.
At A A however plates are secured to the case and in each
of these plates is a threaded hole. Thumbscrews B B with broad heads & engage
in the threaded holes of the plates. Standards C, C, are provided and these have
The screws B pass through the slots c.
slots c c.
It will be readily understood from the drawings that by the means above
indicated, or by equivalent mechanism the instrument may be raised or lowered
as required and securely fixed in the position so that the player may readily
reach the keyboard. For short players (children say) the pedal D will be con-
veniently accessible but when the piano is to be used by a player tall enough to
require it to be raised to its highest position or nearly so, this pedal will be at a
height that will not allow the player readily to use it and a secondary pedal E is
provided for such cases.
The secondary pedal, as shown, consists of a simple stirrup piece suspended by
say a hook and ring from the pedal so as to be easily detached when desired. As
shown in the drawings the pianoforte is one of four octaves only and has but one
pedal but it is evident that the instrument may be made larger and with the usual
two pedals.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that.what
I claim is:
1. A pianoforte or other keyboard instrument so mounted that it may be raised
or lowered in order to bring the keyboard to a level suitable for different
performers.
2. In a piano or other keyboard instrument capable of being raised or lowered
as set forth, the secondary pedal E suspended from the principal pedal as set
forth.

WILLIAM CHARLTON BLACKETT 16 Wharncliffe Street Newcastle upon Tyne,
and St. Thomas Street Newcastle upon Tyne Organ Builder and Tuner do hereby
declare the nature of this invention to be as follows :--
A. valve, or pallet constructed of wood, metal, silk, leather, or other suitable
5 materials in the form of a bellows, and applied so that one side will be the pallet,
or valve, to open or close against an outlet, or inlet, and the opposite side to be
held in suspension by suitable means, so that the bellows or flexible part is
partially expanded, and will receive the pressure of air, water, or other fluids
(according to what purpose the invention is applied) thereby causing the valve, or
pallet to be free from the said pressure, and easily opened or closed, and quiet in
action.
This invention will be very valuable in organ-building when used in the sound
boards and actions-pneumatic or otherwise.

WILLIAM CHARLTON BLACKETT 16 Wharncliffe Street, Newcastle on Tyne
Organ Builder, of the firm of Blackett and Howden Organ Builders, St. Thomas'
Street Newcastle on Tyne 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 valve will be most valuable in organ building, and may be constructed of
wood, leather and felt or other suitable materials, as may be desired, and in the
form of a bellows, same as, or similar to the inclosed drawing, so that one side (A)
will be the surface of the valve which covers the hole (B) through which the
compressed air or other fluid is required to be admitted, and the other side, or
opposite surface (C) of the valve is connected to the side (A) by a surrounding of
leather, or other flexible material (D), and held in suspension by a suitable method
such as a strip of leather, tape, wire, or cords (E). The surfaces (C and D)
relieve (A) of the surrounding pressure causing it to be easily opened by the
(pull-down" (F). (A) is closed by the spring (G), and has a hole (H) to allow
the valve bellows to collapse when opened on hinge lath (I).

Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. The removing of the surrounding pressure from the seat of the valve making
it easy to open, and quiet in closing.
2. When applied to organ actions it greatly lightens and quietens the "touch" of
the keys, as there is only the valve spring for the action to pull against.
3. When applied to certain pneumatic actions in organs, it promotes quickness in
the repetition.

Improvements in Scales for Readily Ascertaining the Measurement of
Properties Shewn on Ordnance Maps.
I, WILLIAM JAMES VILLAR of 10 Hammet Street Taunton, Somersetshire,
Land Agent, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
For the purpose of readily ascertaining the measurement of town property shown
on ordnance maps, I construct a scale graduated to 50 of the real dimensions of
the property or 41.66 feet to one inch. Figure 1 of the accompanying drawings
represents such a scale which is divided in parts of 100 feet, say three of them as
here shewn as a convenient length for surveyors and general use and marked
accordingly. Each 100 feet length is divided in ten parts and each such part
subdivided in 5 or 10 parts. These "100" divisions "10" divisions, and sub-
divisions are marked as shown. The numbers denoting the subdivisions are for the
sake of clearness arranged slanting as shewn. The aforesaid graduations may be
applied to paper, card-board, wood, ivory, bone, celluloid metal or other suitable
material; the paper ones would be cheap and suitable for the general public,
while those on ivory or other more lasting material would be more suitable for
surveyors.
I prefer to combine the above scale on the same piece of material with an
ordinary scale for measuring landed property on the ordnance map. Such a scale
is shewn at Figure 2. It is arranged say to take a mile (5,280 feet) in length
equal to 6 inches or 880 feet to one inch. This scale is divided into 50 feet
divisions as far as they will go and marked accordingly by figures say every
10 divisions and also into 4 quarter mile divisions and marked accordingly. I may
also opposite to this scale apply chain divisions as shewn in Figure 3, 80 of them
marked for every ten or fifteen of them, and perch divisions, 320 of them marked
for every 10 and 20 of them.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is.
First. A graduated scale for measuring on the ordnance maps for town property
substantially as described with reference to Figure 1.
Second. A graduated scale for measuring on the ordnance maps for town property
combined with a scale or scales for measuring on the ordnance maps for landed
property substantially as described with reference to Figures 2 and 3.

A Combined Mixing and Stirring Spaddle and Thermometer.
GEORGE SNIDER FERGUSON Confectioner Detroit, Michigan, U.S.A., and
GEORGE GRAY Ice Dealer Detroit Michigan, U.S.A., do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
Our invention relates to a combined mixing and stirring spaddle and thermometer
and has for its object to provide a tool for mixing and stirring heated mixtures of
every description which will constantly indicate the temperature of the same.
These mixtures may be fluid, semi-fluid or viscous, such as the saccharine masses of
confectioners, fruits and jellies, varnish potash, soap, the masses usually prepared
by chemists and pharmacists and all other mixtures whether for dairy, domestic or
other uses.
According to our invention we are enabled to save a considerable amount of time
which is generally employed in removing a vessel containing such hot mixtures
from the fire, while at the same time avoiding the liability to scorching and burning
to which those who remove the vessel may be otherwise exposed.
In the accompanying drawings,
Fig. 1 is a perspective view of our improved mixing and stirring tool or
device,
Fig. 2 being a vertical section thereof.
Our improved spaddle consists of a spatula shaped piece or bar A of wood, metal,
porcelain or other suitable material (Fig. 1) in the front part of which is formed a
recess e terminating with a circular perforation A¹. In the recess e is located the
thermometer C¹ the lower part of which including the bulb C is protected by two
shield plates D and D¹ screwed to the spaddle in the manner shown in Figs. 1 and 2
and curved inwardly at their lower ends (Fig. 2). The mixture gains access to
the bulb C through the perforation A'.
As shown in the drawings, the thermometer C¹ is located in the lower part of the
recess e; it may however be moved up and down therein and fixed in the desired
position by a fly nut such as f, as shown in dotted lines in Fig. 1 in which case the
instrument occupies its uppermost position. The plated screwed upon the spaddle A
assists in holding the thermometer in position. a is a perforation through which a
string or cord may be passed and tied for the purpose of suspending the mixing
tool to a nail or hook. Fig. 1 fully illustrates the shape which I prefer to give to
my improved combination tool, although it is obvious that any other similar shape
may also answer the purpose.
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 as our invention
The combination of spaddle and thermometer with circular and elongated opening
in which the thermometer can be moved up or down as required.

Improvements in Dress Fabrics known as Crapes.
I, WILLIAM EDWIN BRIGGS PRIESTLEY, of Albion Mills, Laisterdyke,
Bradford, in the County of York, Stuff 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 has for its object, the rendering of a well known fabric called
Crape, more serviceable than hitherto.
The fabric is of delicate construction and is liable to loose its form and be
rendered worthless by damp and rain.
By subjecting the material in the piece to the process of waterproofing, I
thereby render the fabric not only impervious to rain, but its form and appearance
is preserved and thus the fabric becomes more durable and therefore more
serviceable than hitherto.
The waterproofing may be accomplished by any of the well known processes
now in common use for rendering imperial mantle cloths and dress goods water
repellent; as for example, passing the crape fabric through waterproofing machines
and subjecting it to the various solutions known as artificial gums and other
waterproofing compounds, treating it in a similar manner as light dress fabrics.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is: :-
A waterproof crane
