SAMPLE OR CONVEYING BAG.

SPECIFICATION forming part of Letters Patent No. 643,291, dated February 13, 1900. Application filed July 18, 1899. fierial No. 724,273. (No model.)

To aZZ whom it may concern.-

Beitknown thatI, OSCAR HorFMANN,a subject of the Emperor of Germany,and a resident of Nuremberg, Bavaria, in the Empire of Germany, have invented certain new and useful Improvements in Sample or Conveying Bags, of which the following is a specification.

This invention has for its object a samplebag or conveying bag formed of paper, strengthened by linings or the like of some suitable fabric or material, which bag isextremely 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, while the side seams are formed by folding and gum ming 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.

In the accompanying drawings a representation of this improved bag is shown, which will now be more particularly described.

Figure 1 is a vertical section of the bag on the linesA Band C D of Fig. 3; Fig. 2, aview in perspective of the whole arrangement, and Fig. 3 a cross-section of the connection.

The bag is made by a sheet of paper, combined with a lining or the like of fabric, being bent upward from its center to both sides, so that thus a bottom surface h is formed, and the bent-up surfaces form two sides a and b of the bag. By bending inward a portion of the said sides a b the narrow or remaining sides 0 d of the bag are formed, the encountering edges of which are overlapped or folded together in the manner shown in Fig. 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 b c d, are bent upward and connected with the narrow sides 6 d of the bag by means of wire clamps or staples f. Fur- 5o ther, a sure connection of these flaps 6 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 g 5 5 in several coils through suitable successive holes in the flaps e and in the side seams formed by the folding in the manner shown in Fig. 1. These carrying-bands g, the loose ends of which are provided with handles 0 to afford a better hold, as shown in the drawings, are passed along the side seams 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 bands '0', inserted in the fold or connection of the side seams.

The carrying-bands may also be sewed on or attached in any other suitable manner instead of being fixed with clasps.

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- As an article of manufacture, a sample or conveying bag comprising a single sheet of material folded upon itself with inwardlyturned overlapping side edges and bottom
