of Middlesex, Manufacturer, for the Invention of "IMPROVEMENTS IN THE
MANUFACTURE OF BARRELS, BOXES, CANISTERS, CARTRIDGES, AND OTHER
SIMILAR ARTICLES."
Sealed the 13th July 1877, and dated the 19th January 1877.
PROVISIONAL SPECIFICATION left by the said Alfred George Speight at the
Office of the Commissioners of Patents on the 19th January 1877.
ALFRED GEORGE SPEIGHT, of 207, City Road, in the County of Middlesex,
Manufacturer. " IMPROVEMENTS IN THE MANUFACTURE OF BARRELS, BOXES,
CANISTERS, CARTRIDGES, AND OTHER SIMILAR ARTICLES."
The object of this Invention for an improvement in the making of tubes or
cylinders made with wood and paper, cardboard, or pasteboard combined, or paper,
cardboard, or pasteboard only, for the manufacturing of barrels, 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 preserved from atmospheric
influences. Barrels, boxes, canisters, and receptacles for matters of this character
are usually made, if from wood, from cut blanks or pieces of wood, which are rolled
or bent round and forced into moulds with wood blocks and wedges; when barrels,
boxes, or canisters are made from paper, cardboard, or pasteboard, they are usually
made by cutting blanks, pieces, or sheets to the required size; they are then pasted
and rolled round wood rolls or metal tubes commonly called formers. Whereas
according to my Invention I produce a barrel, box, canister, or receptacle of an
effective and ornamental appearance with considerable flexibility, toughness, and
economy in the cost of production, as one half the labour is saved.
I proceed to describe one mode which I adopt in producing articles according to
my Invention; I cut blanks or sheets of wood of proper or suitable sizes, I also cut
blanks or sheets of paper, cardboard, or pasteboard of corresponding sizes, I then
paste, glue, or otherwise cement one side or surface of the wood, I then line or lay
on the cut blank or sheet of paper, cardboard, or pasteboard on the adhesive side of
377

page_text: the wood, and press the two blanks or sheets together; I then cut pieces of suitable
sizes from the cemented sheets of wood and paper, cardboard and pasteboard
combined; I then cover one side of each cut piece of wood and paper, cardboard, or
pasteboard combined with paste, glue, or other adhesive agent, and press the two
cemented sides together, so as to show the wood on both sides, or the interior and
exterior of the tube or cylinder, and by the insertion of the paper, cardboard, or
pasteboard, between the two sheets of wood I produce considerable flexibility and
toughness. The pieces or sheets may be both of equal sizes, but I prefer the one
piece that is to be used for the inside or interior of the tube or cylinder to be
shorter than the piece or sheet that forms the outside or exterior of the tube or
cylinder, so as to allow the outside piece or sheet to overlap the inside piece or sheet
about one inch for the purpose of producing a neater and better fitting joint.
Another mode may be adopted by lining one piece or sheet of wood only instead
of both pieces or sheets with paper, cardboard, or pasteboard, or inserting one piece
of paper, cardboard, or pasteboard between two pieces or sheets of wood, but I
prefer the former. I then. roll or bend round on a block, core, or mandril the
cemented material, and place the said cemented material with the block, core, or
mandril into a mould of the required shape or form, I then withdraw the block,
core, or mandril, leaving the cemented material only in the mould; I then insert in
the place of the block, core, or mandril an india-rubber bag, having an air cock
with a piece of flexible tubing attached to the same, and I fix or otherwise attach the
said piece of flexible tube on to an air pump; I then pump or force air into the india-
rubber bag for the purpose of pressing or forcing the material into the required
shape, whether cylindrical, quadlilateral, or otherwise. I usually allow the pressure
to remain one hour before removing the tube or cylinder from the mould; the
amount of pressure required depends entirely upon the thickness or substance of the
material used. When a greater amount of pressure is required I prefer having a
cap or stop attached to each end of the mould to prevent the bursting of the india-
rubber bag. The moulds may be made of wood, metal, glass, earthenware, or
porcelain.
If a barrel, box, or canister is required to have figures or designs raised or
embossed round the exterior of the tube or cylinder, I prepare or soften the wood,
or wood and paper, cardboard or pasteboard, by any known means for the purpose
of bringing the same to a more plastic condition, and I also use a mould in two or
more parts or sections with the figures or designs cut, engraved, or cast in the
interior of the said parts or sections of the mould; in this case I fasten the parts
or sections together with rings fitted to the outside or exterior of the mould. When
the tube or cylinder is sufficiently dry to allow of its being removed from the
mould I release the air, and remove the india-rubber bag; I then place the mould
with the tube or cylinder therein in an oven, stove, or hot chamber, in order to be
baked, heated, or dried, and to impart rigidly to the article.
I
I do not confine myself to making any particular length of tube or cylinder;
prefer making them of sufficient lengths to allow the said tube or cylinder to be cut
into two or more parts, as required, and for that purpose I place the tube or
cylinder upon a block, core, or mandril, and fix the same in a lathe, and cut to the
required lengths by knife or chisel or other known means; I then cut or stamp out
discs or pieces of the cemented material for the purpose of forming the lids and
bottoms of the barrels, boxes, canisters, and dredgers, as before described, and fix
the said discs or pieces by the ordinary known means of tin or other metal rims;
or I use the ordinary tin or other metal lids and bottoms for finishing the barrels,
boxes, and other receptacles.
In making tubes or cylinders of paper, cardboard, or pasteboard only for the
manufacture of barrels, boxes, canisters, dredgers, cartridges, and other similar
articles, I adopt the same method as before described.
