Improvements in and relating to Packing Boxes and the like.
I, THOMAS KAY, of Thomas Kay and Company, Packing Case Works, 21,
Cathedral Street, in the County of the City of Glasgow, do hereby declare the nature
of my invention to be as follows:-
-
This invention has reference to improvements in and relating to wooden packing
boxes or shipping cases and the like, and comprises a new or improved method of
preventing the boxes being tampered with, without showing external evidence of
same.
These boxes are usually constructed of boards secured together by tongues or
feathers and grooves, or by dowels, and my improvements consist in coating these
tongues with colloid prepared in a state of thin solution or what is known in the
trade as a thin solution of scole liquid glue so that when these tongues are inserted
in the grooves and the solution hardens, the boards are thoroughly cemented and
bound together.
In carrying these improvements into practice the boards after passing through
the usual tonguing and grooving machine are with the tongued edges passed over
a grooved roller mounted and rotated within a tank or vessel containing the colloid
solution, so as to coat said tongues and then within a space of say 15 minutes these
tongues are inserted into the grooves of the adjacent boards and hammered together,
and the solution will thoroughly bind them together.
The boards of the bottom and top of case can have their rims or edges coated
with the colloid solution; or the lid can be fastened down in the ordinary manner.
The meeting edges of the four sides of box may also be cemented together by
the colloid solution.

I, THOMAS KAY, of Thomas Kay and Company, Packing Case Works, 21,
Cathedral Street, in the County of the City of Glasgow, do hereby declare the nature
of my invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement, in writing, that
is to say:-
This invention has reference to improvements in and relating to wooden packing

same.
These boxes are usually constructed of boards secured together by tongues or
feathers and grooves, or by dowels, and my improvements consist in coating these
tongues with colloid prepared in a state of thin solution or what is known in the
trade as a thin solution of "scoli" liquid glue to which it is preferred to add
methylated spirits to prevent frothing so that when these tongues are inserted in
the grooves and the solution hardens, the boards are thoroughly cemented and
bound together.
In carrying these improvements into practice the boards after passing through
the usual tonguing and grooving machine are with the tongued edges passed over
a grooved roller mounted and rotated within a tank or vessel containing the colloid
solution, so as to coat said tongues and then within a space of say 15 minutes these
tongues are inserted into the grooves of the adjacent boards and hammered together,
and the solution will thoroughly bind them together.
The boards of the bottom and top of case can have their rims or edges coated
with the colloid solution, or the lid can be fastened down in the ordinary manner
The meeting edges of the four sides of box may also be cemented together by
the colloid solution.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is :-
First. The use of a solution of colloid for coating the tongues or boards of pack-
ing boxes and the like, substantially as set forth.
Second. Packing boxes and the like, put together with colloid solution to prevent
them being tampered with, substantially as set forth.
