Year: 1873

page_text: LETTERS PATENT to Alfred George Speight, of Spencer Street,
Goswell Road, in the County of Middlesex, Manufacturer, for the
Invention of "IMPROVEMENTS IN THE MANUFACTURE OF BOXES, CANISTERS,
DREDGERS, CARTRIDGES, AND OTHER SIMILAR ARTICLES."
Sealed the 6th January 1874, and dated the 11th July 1873.
PROVISIONAL SPECIFICATION left by the said Alfred George Speight
at the Office of the Commissioners of Patents, with his Petition, on
the 11th July 1873.
I, ALFRED GEORGE SPEIGHT, of Spencer Street, Goswell Road, in the
County of Middlesex, Manufacturer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF BOXES,
CANISTERS, DREDGERS, CARTRIDGES, AND OTHER SIMILAR ARTICLES," to be as
follows:-
The object of this Invention is the manufacture of improved boxes,
canisters, dredgers, cartridges, and other similar articles, so as to adapt
them for the reception of substances or matters requiring to be kept
clean, and to be preserved from damp and other atmospheric influences;

page_text: and my improved boxes, canisters, dredgers, and receptacles are especially
suitable for the reception of acid and pungent matters and substances
likely to penetrate porous receptacles.
Boxes, canisters, and receptacles for matters of this character are
usually made of metal or pottery, whereas according to my Invention
I produce an effective and cheap article (with sufficient rigidity,
durability, and impenetrability) of cardboard, millboard, or pasteboard,
or of paper pulp, or pressed paper, or of parchment, vellum, or skin, or
other animal integument, or of scaleboard; and such material I coat
with liquid glass or silicate solution on the inside or on the outside, or
both on the inside and outside.
I proceed to describe one mode which I adopt in producing articles
according to my Invention.
I cut blanks or pieces of proper size from the sheets, boards, or
material; I bevil or chamfer the edges intended to be brought together
if a neat fit or joint is required when thick material is used; I then
soak the blank in hot size or other glutinous or stiffening matter; to
give it consistency; I then roll, bend, or fit it on a mould, block; core,
mandril, or counter matrix, and I place the same with the material
thereon in a matrix counter mould, or outside mould, which is
preferably formed with perforations or orifices, and thus the required
shape, whether cylindrical, quadrilateral, or otherwise, is imparted to
the box or article; I then place the article with its mould and
counter mould in an oven, stove, muffle, or hot chamber, in order that
it may be baked, heated, or dried. When dry I cement or otherwise
fix together the edges. For this purpose I place the article on a
block of the corresponding shape, and I wind around the article a
flexible band or web to hold it together. Next I apply the liquid
glass or silicate solution by a sponge or brush, or other means; I
then attach a bottom to the article, after having prepared the same,
of the material of which I make the body of the article, and after
having coated it with the silicate solution I prepare and apply the
lid with a flange in the same manner. The whole is then left to dry.
The same method may be adopted with obvious modifications for scale-
board, parchment, vellum, or skin, or other integument.
The article may also be moulded into shape if brought to a plastic.
The article may also be moulded into shape if brought to a plastic
condition..

page_text: When I adapt the Invention to the manufacture of dredgers or
receptacles contrived for the dredging, sprinkling, or scattering of
powders or pulverized substances, I form a number of orifices or per-
forations in the top or other convenient part of the receptacle, and I
propose to protect these orifices with metal cyclets or ocillets.
:
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred George Speight in the Great Seal Patent
Office on the 9th January 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
GEORGE SPEIGHT, of Spencer Street, Goswell Road, in the County of
Middlesex, Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of July, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Alfred George Speight, Her special license
that I, the said Alfred George Speight, my executors, administrators,
and assigns, or such others as I, the said Alfred George Speight, my
exccutors, administrators, and assigns, should at any time agree with
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS
IN THE MANUFACTURE OF BOXES, CANISTERS, DREDGERS, CARTRIDGES, AND OTHER
SIMILAR ARTICLES," upon the condition (amongst others) that I, the said
Alfred George Speight, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said In-
yention, and in what manner the same was to be performed, and cause
the same to be filed in the Great Seal Patent Office within six calendar
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alfred George Speight, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and
by the following statement thereof; that is to say :-
-
The object of this Invention is the manufacture of improved boxes,
canisters, dredgers, cartridges, and other similar articles, so as to adapt
them for the reception of substances or matters requiring to be kept
clean, and to be preserved from damp and other atmospheric influences;
and my improved boxes, canisters, dredgers, and receptacles are especially
suitable for the reception of acid and pungent matters and substances
likely to penetrate porous receptacles.
Boxes, canisters, and receptacles for matters of this character are
usually made of metal or pottery, whereas according to my Invention
I produce an effective and cheap article, with sufficient rigidity,
durability, and impenetrability, of cardboard, millboard, or pasteboard,
or of paper pulp, or pressed paper, or of parchment, vellum, or skin, or
other animal integument, or of scalcboard; and such material I coat 1
with liquid glass or silicate solution, or as it is sometimes called solublo
glass, on the inside or on the outside, or both on the inside and outside.
I proceed to describe one mode which I adopt in producing articles
according to my Invention.
I cut blanks or pieces of proper size from the sheets, boards, or
material; I bevil or chamfer the edges intended to be brought together
if a neat fit or joint is required (when thick material is used); I then
soak the blank in hot size, or other glutinous or stiffening matter, or
otherwise apply the same to the blank to give it consistence; I then
roll, bend, or fit it on a mould, block, core, mandril, or counter matrix,
and place the same with the material or blank thereon in a matrix
counter mould, outside mould or frame, which is preferably formed
with perforations or orifices. This outside mould or frame may consist
of wire wound spirally, and thus the required shape, whether cylindrical,
quadrilateral, or otherwise, is imparted to the box or article; I then
place the article with its mould and counter mould in an oven, stove,
muffle, or hot chamber, in order that it may be baked, heated, or dried.
When dry I cement or otherwise fix together the edges. For this
purpose I place the article on a block of the corresponding shape, and
I wind around the article a flexible band or web to hold it together, 3
which is afterwards removed. Next I apply the liquid glass, or soluble
glass, or silicate solution by a sponge or brush, or other means; I then

page_text: attach the bottom to the article, after having prepared the same, of
the material of which I make the body of the article, and after having
coated it with the silicate solution, I prepare and apply the lid with a
flange in the same manner. The whole is then left to dry.
attach the bottom to the article, after having prepared the same, of
the material of which I make the body of the article, and after having
coated it with the silicate solution, I prepare and apply the lid with a
flange in the same manner. The whole is then left to dry.
The same method may be adopted with obvious modifications for scale-
board, parchment, vellum, or skin, or other integument.
The article may also be moulded into shape if brought to a plastic
condition.
When I adapt the Invention to the manufacture of dredgers or
receptacles contrived for the dredging, sprinkling, or scattering of
powders or pulverized substances, I form a number of orifices or per-
forations in the top or other convenient part of the receptacle, and
sometimes I protect these orifices with metal eyelets.
Sometimes in carrying out the Invention I take the cylindrical,
tubular, or otherwise shaped body of the cardboard or pasteboard box
formed as above described, or otherwise formed, and I dip or immerse
it into a silicate solution, or liquid glass, or soluble glass, so that it
receives a coating of such silicate or liquid or soluble glass on both
its interior and exterior surfaces; a piece of cardboard or pasteboard
is then prepared to form the bottom of the box, and it is dipped into
the silicate so that it may be coated thereon on one or both surfaces,
or the silicate is applied by a brush or otherwise; the bottom is then
applied to the tubular or cylindrical body of the box. The silicato
serves as a cementing material to attach the bottom piece and the
body of the box firmly together, and if there is to be a fixed top or
cover, this is prepared and applied and attached in like manner;
the box is then placed in a heated drying stove, so as to be stoved,
dried, or fired. The cylinder or tube may be immersed or dipped
twice or oftener; or the lid or cover may be made in any ordinary
manner, and fitted on the body of the box; or a lid or cover of tin
or other metal or suitable ordinary material may be used, and lined
with paper, cardboard, or pasteboard, silicated as above described; or
the lid, manufactured and silicated according to my Invention may be
protected by metallic edges.

page_text: of the perforations, because when the covers or tops are dipped into
the silicate this chemical agent hardens around the edge or periphery
of the holes or perforations, and forms a protective border.
I find that an excellent liquid glass for carrying out my Invention
is a solution of silicate of soda at 75° Twaddle, used in a hot or cold
state, and the heat of the stove in which the coated pasteboard, card-
board, or millboard is dried may be 80° or 120° Fahrenheit; but other
alcaline silicates and other strengths or degrees of the hydrometer and
other temperatures may be used, as will be obvious to any competent
workman.
Having now described the nature of the said Invention, and the
manner in which the same may be carried into practical effect, I declare
that I do not claim as of my Invention the manufacture of boxes of
cardboard, paper, pasteboard, millboard, paper pulp, pressed paper,
_scaleboard, parchment, skin, vellum, or integument, apart from the 1
application and use of my Invention; but that what I do claim
is, the employment of liquid glass, soluble glass, or silicate solution,
substantially in the manner and for the purposes described.
In witness whereof, I, the said Alfred George Speight, have here-
unto set my hand and seal, this Eighth day of January, in the 2
year of our Lord One thousand eight hundred and seventy-
four.
