We, WILLIAM DICKIE and WILLIAM INGLIS, both of 69 Virginia Street, Glasgow,
Lanarkshire, Paperbag Manufacturers, do hereby declare the nature of our invention
to be as follows-
Our Invention has reference to improvements in the manufacture of specially lined
paper bags, for the purpose of making them impervious or nearly impervious to the
atinosphere or its humidity or moisture-and preserving the materials enclosed within
the bags from the deleterious action and effects thereof.
And the nature and novelty of our Invention consist in the adaptation and making
of the lining of such bags of waxed tissue paper or of thin parchment paper (which
are in use for other purposes). This new or improved lining of waxed tissue or thin
parchment paper is essentially cut and made to the same size as the outer strong bag
and in the same manner that other ordinary lined bags have been made, that is, first
gumming up the centre overlapping edges of the inner lining before gumming up the
edges of the outer strong bag over it. And then in folding and gumming the bottom
ends of both thicknesses of paper in the same manner that the bottoms are folded and
gummed of single bags and other ordinary lined bags, to make them practically
air tight
Improvements in Paper Bags.
We, WILLIAM DICKIE, and WILLIAM INGLIS, both of 69 Virginia Street, Glasgow,
Lanarkshire, Paper-bag Manufacturers, do hereby declare the nature of our said
Invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement in writing, reference
being had to the accompanying Sheet of Drawings, and to the letters and figures
marked thereon, that is to say :-
Our invention has reference to improvements in the manufacture of specially lined
paper bags, for the purpose of making them impervious or nearly impervious to the

page_text: atmosphere, or its humidity, or moisture, and preserving the materials enclosed within
the bags from the deleterious action and effects thereof.
And the nature and novelty of our Invention consist in the adaptation and making
of the lining of such bags of waxed tissue paper or of thin parchment paper (which
are in use for other purposes). This new or improved lining of waxed tissue or thin
parchment paper is essentially cut and made to the same size as the outer strong bag
and in the same manner that other ordinary lined bags have been made, that is, first
gumming up the centre overlapping edges of the inner lining before gumming up the
edges of the outer strong bag over it. And then in folding and gumming the bottom
ends of both thicknesses of paper in the same manner that the bottoms are folded and
gummed of single bags and other ordinary lined bags, to make them practically
air tight.
And in order that our Improvements and the manner of performing or carrying
the same into effect or practice may be properly understood, we have hereunto
appended an explanatory Sheet of Diagram Drawings, in which the same reference
letters are used fo indicate corresponding parts in all the figures where shown.
Figure 1 shows the two pieces of paper A, B, forming the outer strong bag, and
the inner lining of the wax or tissue paper, respectively laid over the top of the former
ready for being pasted or gummed down the right hand edge a, a, b, b, of both sheets
and along the half of the bottom b₁, b¹, a², a², so that the left hand edges 62, a² of both
sheets are first folded in, one after the other, and the right hand edges a, b, then pasted
or gummed down over these respectively at the centre line a as indicated by the dotted
lines a³, a³ ³, 1. Figure 2, shows the bag so folded and pasted or gummed with the
joint a, a, up the centre, then the bottom is formed by folding in the right hand,
corner A first, and the left hand corner A² afterwards, and gumming this down over
the former so as to form the joint a', a', across the bottom of the bag. Then the
centre doubled corners c, c, are folded in and pasted or gummed down as shown in
Figure 3, which completes the bags ready for use, all so far air tight or impervious
to the humidity or moisture of the atmosphere owing to the inner lining of wax or
tissue paper B being all jointed and closed down within the outer bag sheet A.
Figure 4, shows a perspective view of one of these bags as filled, the top edges d, d,
being folded down much as the bottom edges a', a', were folded, only made to overlap
each other at the upper edges d, d, to a very much greater extent, with both doubled
ears d', d, finally doubled over the centre joint, as indicated in dotted lines at d², d²,
ready for being secured by string; all preferably without being pasted, or gummed,
at the top edges or folds, although this might be done when desired, by gumming the
inner upper edge d of the bags, and only require to moisten them when closing the
bags, as envelopes are closed.
:
Having now particularly described and ascertained the nature of our said Invention
and in what manner the same is to be performed, we declare that what we claim is :-
The manufacture of paper bags with inner linings of waxed tissue paper, or thin
parchment paper, or other equivalent, substantially as and for the purposes herein
described.
