PROVISIONAL SPECIFICATION.
Improvements in Boxes or Cases for Postal or other Uses.
We, HUGH THOMAS EASTMAN the Younger of 23 Bucklersbury in the City
of London, Surveyor, and THE "DETECTER" PATENT SAFETY POSTAL BOX
SYNDICATE LIMITED of 1 and 2 Steward Street, Bishopsgate, in the County of
Middlesex, Box Manufacturers do hereby declare the nature of this invention to
be as follows:-
This invention relates to improvements in the construction of boxes or cases of
wood or other suitable material and of the lids or covers thereto, so that they may
be better adapted for use in containing and protecting articles or goods during
transmission through the post and for other purposes, and so as to permit of the
contents of the boxes, or cases being examined by removal of the covers or lids
and the replacement of the same without injury to box, or lid, or contents.
According to our invention we form the box or case with slots at the sides
passing at one or both sides through the wall of the box or case and upon the
underside of the lid or cover, in a dovetail groove is retained with capability of
sliding lengthwise of its retaining groove, a correspondingly shaped bar, so that
when the box lid or cover is placed in position, the one end of the bar is inserted in
the one slot and allowed to protrude from the wall of the box and the lid or cover
being pressed home on the box the bar is pushed from the outer side of the box on
one side so that its other end is caused to enter the slot in the opposite side, or wall
of the box and the lid is locked; the reversal of the operation will enable the lid
to be removed and so on.
The box may be made as or substantially as described in the Specification of
Letters Patent granted to William Heatley dated October 9th 1891 No. 17215 and
the lid may have the dovetailed recess and its bar formed, or formed and produced
substantially as therein set forth, but it is equally applicable to the securing of the
lids or covers of other boxes or cases and the sliding bar may be secured to the lid
by equivalent means of retention to the dovetail grooving. The bar may be
conveniently shifted in position by means of a coin.

COMPLETE SPECIFICATION.
Improvements in Boxes or Cases for Postal or other Uses.
I HUGH THOMAS EASTMAN the Younger, of 23 Bucklersbury in the City of
London, Surveyor and THE "DETECTER "PATENT SAFETY POSTAL BOX
SYNDICATE LIMITED, of 1 and 2 Steward Street Bishopsgate in the County of
Middlesex Box Manufacturers 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 relates to improvements in the construction of boxes or cases of
wood or other suitable material and of the lids or covers thereto, so that they may
be better adapted for use in containing and protecting articles or goods during
transmission through the post and for other purposes and so as to permit of the
contents of the boxes, or cases being examined by removal of the covers or lids and
the replacement of the same without injury to the box, or lid, or contents.

page_text: DESCRIPTION OF THE DRAWINGS.
Fig. 1 is, a plan view of the body of the box looking inwards, the lid being
removed; the right hand half part of the figure shews an alternative form of
construction to that shewn on the left hand half part.
Fig. 2 is a longitudinal section of the box taken on the line 1-1 of Fig. 1 and
also without its lid.
Fig. 3 is an underside view of the lid to fit the box shewn in the previous figs.
Fig. 4 is an edge view longitudinally of the lid and
Fig. 5 is a cross section of the same taken on the line 2-2 of Fig. 3.
Fig. 6 shews by a transverse section, the box with its lid partly entered into its
place in the box.
Fig. 7 shews by a similar view the lid in its closed position and locked.
Fig. 8 shews by a perspective view the box with its lid fitted and locked
therein.
Figs. 9, 10, 11, 12, 13, 14, 15 and 16 shew views corresponding respectively to
Figs. 1, 2, 3, 4, 5, 6, 7 and 8 of a modification in detail of form of the parts
designed chiefly to effect reduction in cost of production, the meeting edges of the
lid and box body simply butting against each other on the flat, instead of the lid
siuking within the inclined edges of box body and the rounding of corners is
dispensed with.
Otherwise the construction may be and is substantially the same, and locking is
effected in the identical manner.
The pins or screws a', a°, as may be dispensed with, in many cases reliance being
had upon the glue, or equivalent holding means, or ordinary jointing of the wood
walls at the corners of the body, an example of which is shewn in the right hand
half parts of Figs. 1, 2, 9 and 10; a³×, a³× being pins of iron or other material
passed through the sides of the box, or sides and bottom of the box.
This construction, whilst presenting a less ornamental appearance, is very
effective and economical to manufacture.
The following references apply to both forms in all main features ;-
-
a is the bottom, a¹, a³, a³, a are the four sides or walls of the box, a are pins of
wood or other material formed with a screw thread, and passed angularly through
the sides of the box, or sides and bottom of the box, to aid in securing the fastening
of the meeting edges of those parts, generally supplementing their hold by the aid
of glue or other adhesive matter.
The upper edges a° of the box sides are formed to incline inwardly from the outer
edge leaving sharp edges thereto, thereby providing angular seats to fit corre-
spondingly inclined meeting edges b¹ of the lid b.
.
The upper corners as of the box may be rounded, as shewn in Figs. 1, 2 and 8,
thereby affording greater neatness and other advantages, the meeting corners of
the lid being correspondingly rounded to fit same.
We form the box or case with slots a' at the sides, passing at one or both sides
through the wall of the box or case; and upon the under side of the lid or cover b,
in a dovetail groove, is retained with a capability of sliding lengthwise of its
retaining groove, a correspondingly shaped bar , so that when the lid or cover b
is placed in position, the one end 63 of the bar is inserted in the one slot a' and
allowed to protrude from the wall of the box as shewn in Fig. 6 and the lid or
cover b being pressed home on the box, the bar 6 is pushed from the outer side of
the box on one side so that its other side is caused to enter the slot a' in the
opposite side, or wall of the box and the lid is locked, see Fig. 7.
The reversal of the operation will enable the lid to be removed and so on. The
bar 63 is prevented from being pushed too far by the shoulder 6 coming against the
inner side wall of the box thus forming a stop.
The box may be made as, or substantially as, described in the Specification of
Letters Patent granted to William Heatley, dated October 9th 1891, No. 17215,

page_text: and the lid may have the dovetailed recess and its bar, formed, or formed and pro-
duced substantially as therein set forth; but it is equally applicable to the securing
of the lids or covers of other boxes or cases, and the sliding bar may be secured to
the lid by equivalent means of retention to the dovetail grooving.
The bar may be conveniently shifted in position by means of a coin.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The hereinbefore described box having shaped outer edges in combination
with a lid having correspondingly shaped outer edges and a sliding locking bar
applied as set forth, said box having slots adapted to receive and fit the ends of the
locking bar as and for the purposes set forth.
2. The described construction of boxes, each with a locking bar attached to its
lid, said bar being capable of being engaged in slots formed in the walls of said box
and of being disengaged therefrom for removal of said lid substantially as and for.
the purpose set forth and illustrated by the drawings..
