"Means for Protecting Sacks, Bags and other like Enclosures or
Wrappings from the Ravages of Vermin."
I, ERNEST GEORGE COOK BOMFORD, of Spring Hill, Pershore, in the County of
Worcester, Farmer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to means for protecting sacks, bags, hop pockets, wrapp-
ings and other like enclosures for grain, flour, roots and other produce and manu-
factured substances from the ravages of rats, mice and other vermin, and also
incidentally to protect the same from damp.
of
My said invention consists essentially of a double or treble sack and in dressing
the inner surface of the material composing the sacks or the like with a solution
gas and Stockholm tar in grease or oil, such as gallipoli colza or other suitable
oil, with or without the addition of chloride of lime or creosote or a solution of
alum and saltpetre or the like, or the said sacks may be dressed with chloride of
lime alone or creosote alone or alum and saltpetre alone. The dressing may be
served upon the fabric or material by dipping or in any convenient way.
In making up a sack or the like, I prefer to make each side of two thicknesses
or layers of material, the inside of the outer one being dressed as described or the
sack may be made in three thicknesses or layers of material the middle one only
of which is dressed as described, whilst in the case of enclosures or bags for
potatoes or roots, the sacking may be served interiorly.
As a modification of my invention, sacks or the like may be woven from
previously prepared hemp, having a dressed core surrounded by plain hemp
or other material.
I wish it to be understood that I do not confine myself strictly to the use of
the compositions or substances herein described, as I may dress the sacks or bags
with any material or substance obnoxious to rats or vermin

"Means for Protecting Sacks, Bags and other like Enclosures or
Wrappings from the Ravages of Vermin."
I, ERNEST GEORGE COOK BOMFORD of Spring Hill, Pershore, in the County of
Worcester, Farmer, do hereby declare the nature of this invention and in what
ד d

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:-
This invention relates to means for protecting sacks, bags, hop-pockets,
wrappings and other like enclosures for grain, flour, roots and other produce, and
manufactured edible substances from the ravages of rats, mice and other vermin,
and also incidentally to protect the same from damp and dry-rot.
One part of my said invention consists essentially in dressing the surfaces or
the inner surfaces of the material composing the sacks or the like with a solution
of gas tar alone, Stockholm tar alone, or both gas and Stockholm tar, in grease or
oil, such as gallipoli, colza or other suitable oil, with or without the addition of
chloride of lime, or a solution of alum and saltpetro or the like, or the said sacks
may be dressed with chloride of lime alone or alum and saltpetre alone.
dressing may be served upon the fabric or material or applied by dipping or in
any convenient way, and when the dressing compositions are composed of more
than one substance, the ingredients are intimately mixed before application.
The
As examples of the proportions in which some of the above-referred to com-
positions are employed, I may make a dressing for sacks by intimately incorporat-
ing together one gallon of Stockholm tar one pint of gas tar and half a pint of
Galipoli or other oil; or I may employ one gallon of Stockholm tar with one
pint of gas tar only; or one gallon of Stockholm tar with one pound of chloride
of Lime, or with one pound of alum, or one pound of saltpetre.
Another part of my invention consists in a double or treble sack with the inner
surface dressed with a composition or material as described, which acts as a
defence against the ravages of rats or vermin.
In making up a sack or the like, I prefer to make each side of two thicknesses
or layers of material, the inside of the outer one being dressed as represented in
elevation in figure 1 and in vertical section in figure 2, whilst figure 3 represents a
portion of the double walls of a sack in vertical section upon an enlarged scale.
a are the outer walls of the sack and the inner walls united together at the
mouth band with the inner surfaces c, dressed as described.
Or the sack may be made in three thicknesses or layers of material, the middle
one only of which is dressed as described, whilst in the case of enclosures or bags
for potatoes or roots, the sacking may be of a single thickness and dressed or
served interiorly.
As a modification of my invention, sacks or the like may be woven from
previously prepared hemp, having a dressed core surrounded by plain hemp or
other material. In this case, the bags or sacks need only be made of one thick-
ness of material. Or the seam at the extreme edges of sacks may be sewn with
prepared or tar-dressed twine, and in order to protect the enclosed produce from
contact from the dressed sewing, I propose to make another and inner row of
stitching of plain or undressed twine or hemp, as indicated by the dotted line d,
in figure 1.
I wish it to be understood that I do not confine myself strictly to the use of the
compositions or substances herein described, as I may dress the sacks or bags with
any kindred material or substance obnoxious to rats or vermin, and the applica- 4
tion of my invention to wrappers, hop pockets and the like differs in no essential
respect from its application to sacks and bags.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
First: Arming sacks, bags, hop-pockets, wrappers and like enclosures with a
dressing or defence of some composition or material obnoxious to rats or vermin,
which dressing is served upon the surfaces, or the inner surfaces, of the material
composing the sacks or wrappers in order to protect them and their contents
against the ravages of rats, mice and vermin.

for edible and like substances with a dressing or defence composed of a solution
of gas tar, or Stockholm or like tar, or both gas tar and Stockholm tar together,
in grease or oil, such as gallipoli, colza or other suitable oil, with or without the
addition of chloride of lime or a solution of alum and saltpetre; or with a dress-
ing of chloride of lime alone, or alum and saltpetre alone, substantially as and
for the purpose described and set forth.
Thirdly Making up sacks, bags, hop-pockets and the like from two or three
thicknesses or layers of material, with the inner surfaces served with a dressing
or defence for protecting said bags and their contents against the ravages of rats
and other vermin, substantially as described and set forth.
Fourthly: Making sacks or the like from prepared hemp having a served or
dressed core, surrounded by plain. hemp or other material, substantially as
described and set forth.
