An Improved Sample Bag or Conveying Bag.
I, OSCAR HOFFMANN, of No. 7, Aufsessplatz, Nuremberg, in the Empire of
Germany, Merchant, do hereby declare the nature of this invention to be as
follows:
This invention has for its object a sample bag or conveying bag formed of
paper, strengthened by linings or the like of some suitable fabric or material, which
bag is extremely suitable for conveying pulverulent materials, such as cement,
meal, or the like. This is attained by the bag being made in one piece, so that
the bottom seam is entirely dispensed with, whilst the side seams are formed by
folding and gumming together the encountering edges, and strengthening the
seam at the points of connection by the insertion of wire clamps. The latter
serve at the same time for attaching carrying bands, which run up both sides
of the bag and serve also as distributors of the load, when the bag is conveyed,
and also allow of the bag being conveniently handled.
The bag is made by a sheet of paper, combined with a lining or the like of
fabric, being bent upwards from its centre to both sides so that thus, a bottom
surface is formed, and the bent up surfaces form the two sides of the bag. By
bending inward a portion of the said sides the narrow or remaining sides of
the bag are formed, the encountering edges of which are overlapped or folded
together and if necessary gummed together so that any escape at these points
of the material or substance contained in the bag is prevented with certainty.
The projecting flaps or lugs formed on the bottom by the folding of the side
walls, are bent upwards, and connected with the narrow sides of the bag by
means of wire clamps or staples. Further, a sure connection of these flaps
with the narrow sides which also affords an increased resistance to bursting at
the most susceptible places of the bag is obtained by passing one of the ends
of carrying bands in several coils through suitable successive holes in the flaps
and in the side seams formed by the folding. These carrying bands the loose
ends of which are provided with handles to afford a better hold are passed along
the side seams and attached thereto by means of wire clamps or staples inserted
through the latter, whereby the pull resulting when the sack or bag is carried
is conveyed to larger surfaces and any tearing or bursting of the bag is as far
as possible, suitably prevented.
After the bag has been filled, it is closed by the upper parts of the walls being
folded over a sheet of cardboard laid therein, and held closed by the bag being
bound with bands inserted in the fold or connection of the side seams.

I, OSCAR HOFFMANN, of No. 7, Aufsessplatz, Nuremberg, in the Empire of
Germany, 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: --
This invention has for its object a sample bag or conveying bag formed of
paper, strengthened by linings or the like of some suitable fabric or material, which
bag is extremely suitable for conveying pulverulent materials, such as cement,
meal, or the like. This is attained by the bag being made in one piece, so that
the bottom seam is entirely dispensed with, whilst the side seams are formed by
folding and gumming together the encountering edges, and strengthening the
seam at the points of connection by the insertion of wire clamps. The latter
serve at the same time for attaching carrying bands, which run up both sides
of the bag and serve also as distributors of the load, when the bag is conveyed,
and also allow of the bag being conveniently handled.
The invention is shown in the accompanying drawings:
Fig. 1 being a vertical section of the bag on the lines A B and CD of Fig. 3.
Fig. 2 a view in perspective of the whole arrangement of the sample bag;
Fig. 3 a cross section of the bag at the point of junction.
The bag is made by a sheet of paper, combined with a lining or the like of
fabric, being bent upwards from its centre to both sides so that thus, a bottom
surface his formed, and the bent up surfaces form the two sides ab of the bag.
By bending inward a portion of the said sides a and b the narrow or remaining
sides c and d of the bag are formed, the encountering edges of which are over-
lapped or folded together as shown in Figure 3 and if necessary gummed together
so that any escape at these points of the material or substance contained in the
bag is prevented with certainty. The projecting flaps or lugs e formed on the
bottom by the folding of the side walls a bed are bent upwards, and connected
with the narrow sides ed of the bag by means of wire clamps or staples f.
Further, a sure connection of these flaps with the narrow sides which also
affords an increased resistance to bursting at the most susceptible places of the
bag, is obtained by passing one of the ends of carrying bands 9 in several coils
through suitable successive holes in the flaps e and in the side seams formed by
the folding, and fastening them in the manner shown in Figure 1. These
carrying bands g, the loose ends of which are provided with handles o to afford
a better hold are passed along the side seams as shown and attached thereto by
means of wire clamps or staples f inserted through the latter, whereby the pull
resulting when the sack or bag is carried is conveyed to larger surfaces and any
tearing or bursting of the bag is, as far as possible, suitably prevented.
After the bag has been filled, it is closed by the upper parts of the walls being
folded over a sheet of cardboard laid therein, and held closed by the bag being
bound with hands or cords inserted in the fold or connection of the side
seams.
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:-
-
A sample bag or conveying bag, characterized by the two side seams of the
bag which is made in one piece with the bottom seam dispensed with, being
formed by folding together the encountering edges of the parts abed (which
are bent upwards and constitute the side walls), and strengthening same by

page_text: means of clamps or staples (f) inserted at the points of connection, which
clamps also serve for attaching flaps (e) projecting from the bottom surface (h)
and carrying-bands (9) to the joints of the side seams, substantially as described.
