We EDWARD ORMEROD Specialist in Concrete of 11 Victoria Road Battersea
Park in the County of Surrey and WILLIAM CULLEN HORNE Merchant of 3 Victoria
Road Charlton in the County of Kent do hereby declare the nature of our Invention
for IMPROVEMENTS IN RENDERING CEMENTS LUMINOUS AND DAMP PROOF to be as
follows:-
:-
Our Invention relates to a method of making cements, plaster of Paris concretes,
& such similar substances, luminous, by the introduction into same, of a phosphor-
escent substance by which means, the article of plaster, or cemented surface, when
exposed to rays of light becomes luminous in the dark, after such exposure, and is
more or less capable of imparting light to other objects, or as in the case of a
ceiling of a room being coated with such luminous cement, is capable at night of
dispelling the darkness therein, such luminous cement being rendered damp proof,
as hereinafter described.
We attach importance in taking for our phosphorescent substance, a luminous
powdered sulphide of calcium, that is of an enduring quality of phosphorescence,
lasting for many hours through a long winters night, we prefer such as is known,
as Puzey's luminous powder, and as used in the manufacture of Balmains luminous
paint, and sold by the proprietors of same at present, at 5a Aldermanbury Postern
London. We take of cement, such as that is known as Keen's Parian or other
suitable makes, in varying proportions, as for instance, 2 lbs to 5 lbs. to 1 lb of the
aforesaid luminous powder, and mix same with water, & then, mould the same
to required shape, in the usual way well known to workers in plaster, or lay it on to
ceiling or wall, by means of trowel.
We secondly attach importance, to placing the moulded articles as soon as they
have been dried, in a bath of paraffin wax & benzoline, or other suitable weather
& waterproofing substances. In the case of using the luminous cement upon a
wall or ceiling, we sponge or brush the surface over, with a solution of paraffin wax
& benzoline, or other suitable damp proofing solution.
The uses of this luminous cement are manifold.
For the garden. Luminous concrete as edging to garden paths, and carriage drives,
for guides, and beacons, at the entrance gates of drives, insides of stables, the base
of balustrades, or the entirety of balustrades.

page_text: For Roads. As luminous beacons at corners of dark country lanes, & at ends
of bridges, ends of walls, & curbs of foot paths, the pedestal of lamp posts, to serve
when the lamps are not lighted.
For Docks. For edging of piers, & wharves, & to guide the whereabouts of certain
positions.
For Waterworks. For the safety & dispatch of night work, by the erection of
luminous guides & beacons, and for fireplug notices on walls.
Canals & Rivers. Especially the key stone, & on each buttress of the arches of
bridges, luminous beacons, to facilitate navigation-also for luminous cementing
the base of all obstructions in the canal paths.
Railways. For the edges of station platforms, & interior of urinals, for edges of
all arch ways, & for luminous bands around pillars or obstructions in pathways-
for concrete letters for names of stations, etc. etc.
Military. For rendering the facing of walls inside of fortifications, enabling
gunners at night to work with comfort by the aid of its feeble light, that would
suffice for working, & yet not be strong enough to show a light to an enemy to
draw the enemy's fire. For outsides of magazines in times of peace, for the sentries
to detect trespassers on dark nights-for luminous guides to be carried by field
batteries, to fix in the ground, & preserve order in the dark.
Naval. For landing parties for surprise operations on a beach, enabling the
party to lay down from their boats luminous guides, so that they can quickly
retrace their steps to regain their boats.
Household. For facing the rises & sides of steps,-for cementing the ceilings or
walls of pantries, closets, & lavatories.
Factories & Mills. For cementing a narrow band luminous about the outside
premises, to guide nightwatchmen, for the entire interior of chambers, in which
explosive manufactures are carried on, so that in safety work can be conducted after
sunset.
Arts & Sciences. For making tiles & plaques of luminous cement, to receive
coloured decorations.
Trades. Match box holders. Toy trade, door handles, & taps, letters, & most
articles that are now made of cement.

Damp Proof.
EDWARD ORMEROD 11 Victoria Road Battersea Park, in the County of Surrey,
Specialist in Concrete & WILLIAM CULLEN HORNE 3 Victoria Road Charlton in the
-County of Kent Merchant do hereby declare the nature of our invention for
IMPROVEMENTS IN RENDERING CEMENTS LUMINOUS & DAMP PROOF, and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :-
The object of our Invention is to provide a means of making Cements Plaster of
Paris Concretes and such similar substances Luminous by the introduction into
same of a phosphorescent substance by which the article of Plaster or .cemented
surface when exposed to rays of light becomes luminous in the dark after such
exposure, and is more or less capable of imparting light to other objects, or as in
the case of a ceiling of a room being coated with such Luminous cement, is capable
at night of dispelling the darkness, such Luminous cement being rendered damp
proof as hereinafter described.
We attach importance in taking for our phosphorescent substance a Luminous
powdered Sulphide of Calcium that is of an enduring character & quality of
phosphorescence lasting for many hours through a long winter night, we prefer
such as is known as Puzey's Luminous Powder and as used in the manufacture of
Balmains Luminous Paint and sold by the proprietors of same at present at
5a Aldermanbury Postern London.
We take of cement such as that is known as Keen's Parian or other suitable
makes in varying proportions as for instance 2 lbs. to 5 lbs. to 1 lb. of the aforesaid
Luminous Powder and mix same with water & then mould the same to required
shape in the usual way well known to workers in plaster or lay it on to ceiling or
wall by means of trowel.
We secondly attach importance to placing the moulded articles as soon as they
have been dried in a bath of Paraffin wax & benzoline or other suitable weather or
waterproofing substance. In the case of using the luminous cement upon a wall or
ceiling we sponge or brush the surface over with a solution of paraffin wax &
benzoline or other suitable damp proofing solution. The uses of this luminous
cement are manifold.
For the garden-luminous concrete as edging to Garden paths and carriage drives
for guides and beacons at the entrance gates of drives insides of stables the base
of balustrades or the entirety of balustrades. For Roads-as luminous beacons at
corners of dark country lanes & at ends of Bridges ends of Walls & curbs of
footpaths the Pedestals of Lamp posts to serve when the lamps are not lighted.
For Docks for edging of piers & wharves & to guide the whereabouts of certain
positions. For waterworks for the safety & despatch of night work by the erection
of luminous guides & beacons and for fire plug notices on walls. Canals & rivers--
especially the Keystone & on each Buttress of the arches of Bridges Luminous
beacons to facilitate navigation also for Luminous cementing the base of all
obstructions in the canal paths,

page_text: Railways for the edges of station platform & interior of urinals for edges of all
archways & for luminous bands around pillars or obstructions in pathways for
concrete letters for names of Stations etc etc. Military-For rendering the facings
of walls inside of Fortifications, enabling gunners at night to work with comfort by
the aid of its feeble light that would suffice for working & yet not to be strong
enough to shew light to an enemy to draw the enemy's fire for outsides of
magazines in times of peace for the sentries to detect trespassers on dark nights
for luminous guides to be carried by field batteries to fix in the ground & preserve
order in the dark.
Naval for landing parties for surprise operations on a beach enabling the party
to lay down from their boats luminous guides so that they can quickly retrace
their steps to regain their boats. Household-for facing the rises & sides of steps for
cementing the ceilings or walls of pantries closets & lavatories Factories & mills-
For cementing a narrow band luminous about the outside premises to guide night
watchmen, for the entire interior of chambers in which explosive manufactures are
carried on so that in safety work can be conducted after sunset. Arts & Sciences.-
For working tiles and plaques of Luminous cement to receive colored decorations..
Trades Match boxholders, Toy trade, Door handles and Taps letters and most
articles that are now made of cement. .
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed we declare that what.
we claim is
Firstly. The rendering of Cements Plaster of, Paris Concretes and such similar
substances Luminous by the introduction of a phosphorescent substance by which
the article of Plaster or cemented surface when exposed to rays of light becomes
luminous in the dark and is more or less capable of imparting light to other
objects.
Secondly. The rendering of such Luminous Cements Damp proof by plunging in a
bath of Paraffin wax & Benzoline or other suitable weather or waterproofing
substance or sponging such luminous cement over with the aforesaid solution or
