'A communication by WILLIAM B. THOMSON, of Detroit, in the County of Wayne,
and State of Michigan, United States of America.
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention to be as follows;-
This invention has for its object an improved box or package of novel and
superior construction and utility and it consists of the construction, combination
and arrangement of devices hereinafter described.
The invention is especially adapted for the construction of boxes from paper,
or paper board, but my correspondent would have it understood that he does
not limit himself solely to any particular material, as the invention may be
applied to the construction of boxes of different materials within the scope of
this invention.
This invention is carried out as follows:-
The body of the box or package may be of any desired form. The body and
the head are primarily formed with downwardly projecting extremities, said
extremities extending downward below the end and one extremity being prefer-
ably longer than the other extremity. The latter may be in the nature of a flange
turned at right angles to the body of the head, the head being set up within
the body a sufficient distance to allow the other extremity of the body to project
beyond the body of the head a distance equal to or greater than the length of
the flange. When the head has thus been located within the body, as above
described, the two extremities are placed in a suitable machine or die and rolled
over and inward together on a curve and in under the head to securely lock the
head and body together. By rolling the extremities over and inward, thus,
and in under the head, my correspondent is enabled to secure superior strength
of joint, especially desirable and effective in a box made of paper, as well as a
tight and compact joint. This rolled joint is found to secure a special stiffness
greater than can be secured in any ordinary manner. By making the extremity
longer than the flange of the head, he is also enabled to roll the edge of the
extremity over and above the edge of the flange, so as to catch and hold the
flange firmly and securely.
A fastening piece or plate may be provided. secured on the outside of said
head or end piece in any suitable manner, as by cement, the periphery of the.
fastening piece projecting snugly up against the inner surface of the roll above
described and downward there against, and forming in the completed article
a projecting rim. The fastening piece being secured. thus snugly against the

page_text: inner surface of said roll or rim and to the outer surface of the end piece, stiffens
the construction of the box very materially and holds the roll or rim firmly in
its rolled position. For a smaller and lighter box, this invention contemplates
dispensing with the fastening piece but for larger and heavier boxes, it is pre-
ferred to use said fastening or locking piece.
For still larger boxes, requiring more strength, this invention contemplates
engaging in under the head a 'strengthening head, fitted in under the head within
the flange before the roll or rim is formed, the periphery of the strengthening
head fitting snugly against the inner circumference of the flange. The ex-
tremities are then rolled, as above described, in under said head with or without
the piece, said piece being preferably employed, the head being located between
the parts. This strengthening head may be made of wood or any other desired
material. It will be firmly held in place by the roll or rim. By its use greater
strength and stiffness at the bottom of the box or package is attained and when
located between the parts the head is not exposed to the weather, or to dampness,
but is thoroughly covered and protected, so that all liability. of contraction and
expansion thereof is entirely avoided. The body may be made of paper-board
rolled and lapped at its edges, into tubular or other form. This construction and
arrangement of the head, and the manner of holding it securely in place answers,
obviously, for either the bottom of a box or package, or for the formation of a
cover therefor, the cover being formed in a manner analogous to that already
described.
When the box or package is completed, this invention contemplates, if desired,
the application of a waterproof coating thereto.
A box so constructed is of the greatest possible strength, the joint of the end
piece with the body being absolutely tight, as well as strong and firm, said roll
or joint being in the nature of a compound roll or curve.

A communication by WILLIAM B. THOMSON, of Detroit, in the County of Wayne,
and State of Michigan, United States of America!
I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street, Manchester, both
in the County of Lancaster, 118, New Street, Birmingham, in the County of
Warwick, and 322, High Holborn, in the County of Middlesex, Civil 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 an improved box or package of novel and
superior construction and utility, and it consists of the construction, combination
and arrangement of devices hereinafter described and claimed and illustrated in
the accompanying drawings, in which:-
Figure 1 is a view in vertical section of a package with its lower flanges pro-
jecting downward into position ready to be rolled to secure the end and body
of the box together.
'

page_text: Figure 2 is a vertical section showing the flanges rolled together into permanent
osition to secure the end and body of the package together, and showing an
dditional locking piece engaged in place.
Figure 3 is an enlarged view showing a partial section of the device provided
vith a strengthening head.
This invention is especially adapted for the construction of shipping and other
packages constructed of paper or paper board more particularly, but is not limited
olely to the formation of the body of the package of any particular material,
as the invention may be applied to the construction of boxes of different materials.
The invention, however, will be described as applicable to a package formed of
paper-board.
The invention will be carried out as follows:
A represents the body of the box or package, which may be of any desired
form.
B is one end or head thereof, as the bottom, for example. The body A and
the head B are primarily formed with downwardly projecting extremities, indi-
cated in the drawings at a and b, said extremities extending downward below
the horizontal portion of the head B, the extremity a of the body being preferably
projected beyond the extremity of the head. The part 6 of the head B may
be in the nature of a flange turned at right angles to the body of the head, the
head being set up within the body a sufficient distance to allow the extremity a
of the body to project beyond said flange. When the head has thus been located
within the body, as shown more particularly in Figure 1, the two extremities a
and 6 being placed in a suitable machine or die are then rolled over and inward
together on a curve and in under the head B to securely unite the head and body
together. By rolling the extremities a and b over and inward and in under
the head thus, a joint of superior strength is secured, especially desirable and
effective in a box made of paper or fibrous material, as well as a tight and com-
pact joint. This rolled joint is found to secure a special_stiffness and a joint
firmer than can be secured in any customary manner. By making the ex-
tremity a of the body longer than the flange 6 of the head, said edge of the body
may be rolled over and above the edge of the flange b to catch and hold said
flange more firmly and securely.
In Figure 2 of the drawing is shown also a fastening or locking piece C
secured on the outside of said head B and in any suitable manner, as by cement,
the periphery of the fastening piece or locking plate C projecting snugly up
against the inner surface of the rolled joint, above described, said fastening
piece at its periphery also projecting downward against said joint. The roller
joint is indicated at Q, and forms in a completed article a projecting ring.
The piece or plate C being thus secured against the inner surface of the roll or
rim and to the outer surface of the head, stiffens the construction of the box
and holds the joint firmly in its rolled position. For a small or light package,
the invention contemplates dispensing with said piece C, but for larger and
heavier boxes said fastening or locking piece may be employed. For still larger
packages requiring more strength, the invention contemplates engaging in under
the head a strengthening head 1, shown in Figure 3, fitted snugly against the
inner surface of the flange b. The extremities a and b are then rolled, as above
described, in under said head D with or without the locking piece C. When
said locking piece is employed, the head D is located between the parts B and C,
as shown in Figure 3. This strengthening head D may be made of any desired
material, and will firmly be held in place by the joint Q. When said head D
is located between the parts B and C, it is not exposed to the weather, but is so
protected that all liability of contraction and expansion thereof is avoided.
The fastening or locking piece C shown in the preceding figures may have
its peripheral flange somewhat extended so as to form a metal shoe C¹ as shown
in Figures 4, 5 and 6, said shoe being constructed with a peripheral recess or
channel to fit over the rolled joint Q, c is the extended or upwardly projecting

page_text: peripheral flange, and C2 the channel or recess. The body of the metal shoe
may be made plain and flat, or it may be corrugated or formed with one or
more beads or corrugations, indicated at c¹, the corrugations being made deep
enough to contact with the floor or other support for the package, said corruga-
tions thus assisting to support the package. At the same time it will be evident
that the corrugations materially strengthen the shoe and cause it to more firmly
support the head B. At the same time, the shoe forms wearing surfaces, pro-
tecting the body and head and the rolled joint from wear and breakage. By
corrugating the body and shoe and making the corrugations of sufficient depth
to assist in supporting the package, the head B is effectually prevented from
springing, and the package is properly supported without springing and is also
protected from injury or wear by the metal surfaces of the shoe. When the
shoe has been slipped into place over the joint, the outer flange and the inner
wall of the channel C2 about the joint may be pressed or clamped upon the joint
to strengthen the joint and to assist in holding the shoe in place, but the shoe
might be secured in place in other ways, if desired.
This construction and arrangement, obviously, may be applied in the con-
struction of the bottom of a package, or in the formation of a cover B¹ therefor,
shown in Figure 2. When the package is completed, the invention contem-
plates, if desired, the application of a waterproof coating thereto.
A box or package so constructed is of the greatest possible strength, the joint
of the end piece 13 with the body being absolutely tight, as well as strong and
firm, said roll and joint being in the nature of a compound roll or curve owing to
the tubular form of the joint in cross section, and its curved outline or contour
round about the end of the package.
Having now particularly described and ascertained the nature of the said
invention. and in what manner the same is to be performed, as communicated
to me by my foreign correspondent, I declare that what I claim is:-
1. A box or package having in combination an end piece formed with a down-
wardly projecting hange at its edge, and a body having one of its extremities
projecting downwardly about and adjacent to the flange of said end piece, said
flange and the adjacent extremity of said body both rolled inwardly together
and in under the end piece in the form of a curve in cross section, making
inwardly turned tubular roll or rim to fixedly unite the body and the end piece,
substantially as set forth.
an
2. A box or package having in combination an end piece formed with a
downwardly projecting flange at its edge, and a body having one of its ex-
tremities projecting downwardly about and adjacent to the flange of said end
piece, said flange and the adjacent extremity of said body both rolled inwardly
together and in under the end piece in the form of a curve in cross section,
making an inwardly turned tubular roll or rim to fixedly unite the body and the
end piece, and an additional fastener rigidly engaged upon said end piece and
joint to lock the joint and prevent the unrolling of the same, substantially as
set forth.
3. A box of fibrous material constructed of an end piece having a downwardly
projecting flange at the edge thereof, a body projecting downwardly about and
adjacent to the flange of said end piece, said flange and the adjacent extremity of
the body both rolled inwardly together in the form of a curve in cross section
making an inwardly turned tubular roll or joint to unite said end piece and
body together, and in combination therewith, a fastener plate of fibrous material
rigidly engaged against the surface of said inwardly turned roll or joint, and
upon the adjacent outer surface of said end piece to form a permanent lock
to prevent the unrolling of said joint, the periphery of the fastening plate pro-
jecting snugly up against the inner surface of the roll, substantially as and for
the purpose described.

page_text: 4. A box or package of fibrous material constructed of an end piece having a
peripheral downwardly projecting flange, a body projecting about the flange
of said end piece, said flange and the adjacent extremity of the body both rolled
inwardly together in the form of a curve in cross section making an inwardly
turned tubular roll or joint to fixedly and immovably unite said end piece and
body, and an additional strengthening head, substantially as set forth.
5. A box or package of fibrous material constructed of an end piece having a
peripheral downwardly projecting flange, a body projecting about the flange
of said end piece, an additional fastener of fibrous material, said flange and the
adjacent extremity of the body both rolled inwardly together in the form of a
curve in cross section, making an inwardly turned tubular roll or joint to fixedly
and immovably unite said end piece and body, the edge of said fastener perma-
nently engaged snugly against the inner surface of said joint and against the
adjacent outer surface of the end piece to form a lock to prevent the unrolling
of said joint, and a strengthening head located between the fastener and said end
piece, the periphery of said strengthening head engaged between said tubular
roll and said end piece, substantially as and for the purpose described.
6. A box of fibrous material constructed of a body, an end piece or head
having their adjacent extremities rolled over and inward, in under the head on
a continuous curve that unites said body and head, and in combination there-
with a fastening or locking piece, whose flange is so formed as to constitute a
peripheral channel or recess to receive and cover said rolled joint, each side of
said channel being clamped one towards the other securely over said rolled joint
to keep the joint from unrolling and to protect the adjacent parts, substantially
as set forth.
