Improvements relating to Coal and other Sacks or Bags.
L, GEORGE BREWIS, of 47, Euston Road, in the County of Middlesex, Coal
Merchant, do hereby declare the nature of this invention to be as follows:-
My invention relates to coal and other sacks or bags and is designed to provide
simple and efficient means for closing and fastening the same.
According to my said invention I provide the sacks or bags with a cover or flap
and an adjustable fastening device which enables the said cover to be secured
tightly over the contents of the sack or bag without leaving a space in which the
same might be liable to be shaken about and broken.
Thus for instance, a coal sack provided with my improved device may always be
closed and fastened although the bulk of an equal weight of coal will necessarily
vary on different occasions.
My improved adjustable fastener is not liable to get out of order and is very
easy to fasten or unfasten so that there will be no difficulty in unfastening the same
in cold weather.
In carrying my said invention into practice I proceed as follows, that is to say,
I provide the sack or bag with a flap or cover adapted to fold over the mouth of
the same and I secure upon the body of the sack two or more spring clips secured
thereon in any convenient manner and I attach to the cover thereof by any suitable
means two or more short lengths of rope provided with knots at intervals along the
same. The sack having been filled the cover or flap thereof is closed and drawn
as tight as possible by means of the aforesaid ropes each of which is then passed
under one of the aforesaid spring clips and is prevented from being drawn under
the same by the engagement of the knots thereon with the said clip. When it is
desired to disengage the rope to raise the flap or cover of the sack all that is
necessary is to pull the same forcibly in the reverse direction to that in which it
was inserted, from under the said clip.
The aforesaid spring clips consist preferably each of a strip of steel secured
upon and adapted to press towards or against a metal plate which is attached to the
body of the sack, or bag, by any convenient means as for instance by rivets or by
metal pieces formed thereon, passing through the material of the sack and turned
up on the other side thereof.
:
I sometimes employ a chain instead of the knotted rope, the links thereof
serving the purpose of the knots and engaging with the spring clip or I provide a
rope, chain or the like having special projections or engagement pieces formed
thereon in any convenient manner.
Moreover instead of a single clip I may provide two or more clips upon the same
plate.
The edges of the clips and plates are suitably bevelled or chamfered to prevent
the abrasion of the rope against the same.
It is obvious that my mvention may be somewhat modified in carrying the same
into practice without departing from the nature thereof.

Improvements relating to Coal and other Sacks or Bags.
1. GEORGE BREWIS, of 47, Euston Road, in the County of Middlesex, Coal
Merchant, 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 :-
My invention relates to coal and other sacks or bags and is designed to provide
simple and efficient means for closing and fastening the same.
The main object of my said invention is to prevent the fraudulent extraction of
coals from coal-sacks by carmen or other employes and the loss of coal in transit
from the wharves to customers' cellars.
According to my present invention provide the sacks or bags with a cover or
flap and an adjustable fastening device which enables the said cover to be secured
tightly over the contents of the sack or bag. I moreover provide around the said
sack or bag suitable strengthening pieces to which the parts of the fastening
devices are directly secured, thus distributing the strain of the said devices over a
considerable surface of the sack and avoiding any liability to tearing of the same.
I am thus enabled to provide a sack or bag which can be securely closed in such a
manner that no space will he left through which the contents would be liable to be
shaken out in transit.
Thus, for instance, a coal sack provided with my improved device may always be
tightly closed and fastened although the bulk of an equal weight of coal will
necessarily vary to a certain extent on different occnsions.
My improved adjustable fastener is not liable to get out of order and is very easy
to fasten or unfasten so that there will be no difficulty in unfastening the same in
cold weather, which is an important advantage in the case of coal-bags.
In the accompanying drawings,
Figure 1 is a front elevation of a sack provided with my improvements.
Figure 2 is a view drawn to an enlarged scale, of a clip or catch as used with my
improved sack.
In carrying my said invention into practice I proceed as follows; that is to say,
1 provide a sack or bag A with a flap or cover B adapted to fold over the mouth
of the same and I secure upon the body of the said sack two or more spring
clips Csecured to strengthening pieces or ribs (in any convenient manner. These
strengthening pieces (consist of bands of suitable material preferably extending
in one piece down the front of the bag and up the back thereof and either attacheil
to or woven into the material of the sack. I moreover attach to the lid or cover
of the bag or preferably to the strengthening band ("by any suitable means two
or more short lengths of chain D. The sack having been filled the cover or
flap B thereof is closed and drawn as tight as possible by means of the aforesaid
chains each of which is then secured by causing one of its links to engage with the
corresponding clip or by passing one of its links under the corresponding clip the
chain in this case being prevented from being drawn from under the said clip by
the engagement of the next link thereof with the said clip. When it is desired to
disengage the chain to raise the flap or cover of the sack all that is necessary is
to pull the same forcibly in the reverse direction to that in which it was moved to
cause its engagement with the said clip.
Each of the aforesaid spring clips C consists of a metal plate E having a strip or
tongue F partly cut therefrom and bent outward as shown in Figure 2, so that the
chain D can be easily connected with and disconnected from the said strip or
tongue. The clip is attached to the body of the sack or bag by any convenient
means as for instance by rivets or by metal pieces formed thereon passing through
the material of the sack and turned up on the other side thereof.
I sometimes employ instead of a chain a knotted rope, the knots therein serving
the same purpose as the links of the chain and engaging with the spring clip; or

page_text: I provide a chain, rope or the like having special projections or engagement pieces
formed thereon in any convenient manner.
Moreover, instead of a single clip I may provide two or more clips upon the same
plate and the construction of the said clip may in some instances be modified by
forming the tongue F of a separate piece of metal welded or riveted to the
plate E.
The edges of the clips and plates are preferably suitably beveled or chamfered.
It will be readily seen that by the position of my improved fastening device the
same are not readily accessible when a number of sacks are placed side by side in
a cart for delivery and a sack cannot be opened without removing the other sacks
bodily therefrom the fraudulent removal of coal in transit to the consumer is thus
very effectually prevented.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it understood
that I claim :—
The improved coal or other sack or bag provided with the lid, flap or cover and
with fastening devices substantially as, and for the purposes above specified.
