IMPROVEMENT INV BAG-FASTENERS.

Speciiication forming part of Letters Patent No. 211,224, dated January 7, 1879; application filed November 8, 1878.

.Ff To all whom it may concern:

Be it known that I, THoMAs GLEARY, of New York city. in the State of New York,have

j invented certain new and useful Iinpro vemcn ts relating to Bag-Fastenings, of which the following is a specification:

W hen grain is carried as freight across the ocean it is necessary, for prudential reasons, to carry a certain portion of the grain in bags. Convenience requires that there'shall be a gathered quantity of the bag on each side at the top to facilitate handling, and it is iinportant for obvious reasons that the mouths of the bags shall be fastened by means which may be closed and opened with little skill or labor, and shall be reliable and durable. lt is furthermore important that the fastenin gs shall allow the holding of 4the greatest quantity of grain in a bag of a givmen size. My invention attains all these ends.

'lhe followin gis a description of what I con sider the best means of carrying out the invention.

The accompanying drawings form a part of this specification.

Figure'l is a side elevation of a full bag,A

showing my improved fastening applied. Fig.

2 is a view of the under side of lmy device,

. below the top to form the required ear or lug when that portion of the material of which the bag is composed situated above the same is drawn together. O1 C2 are strings, by which the mouth of the bag is ultimately secured and held iirmly in the closed position. I employ, in 1 connection, two rigid cheeks, Dl D2, of less length than the entire width of the closed bag, but sufficiently long to extend nearly across the top of the bag when its width is contracted by being filled. Certain parts of these cheeks D1D2 willbe denoted by further marks. These rigid pieces or cheeks may be of various materials, as malleable cast-'iron or brass. I prefer hard wood, and will so describe these parts. Each of my rigid parts D1 D2 is provided with two or more spurs or project-ions, D3, on its inner face, which extends through the material of the bag A and protrudesk beyond. These spurs or project-ions are preferably of metal properly coated to protect them from oxidization. They may be strongly "'secured by screw-threads, as indicated in Fig. 2. Each cheek Dl DZ is also formed with two or more recesses or holes, d, adapted to receive the corresponding spurs D3 of the opposite cheek; Each cheek is perforated, as indicated at di, to allow boththe strings C* C2 to be passed through. Each is also grooved, as indicated by d2, the groove being deep enough near the hole d1 to receive the string C1 or C2, and becoming near the end ofthe cheek much deeper. At the eXtreme end it assumes the form of a longitudinal hole in the pieces Dl D2.

I fasten the material of the bag firmly to the inner faces ofthe cheeks by rivets e, which engage through bot-h the cheek and bag, and also through a thin inner piece of metal, E. The ends of the strings Gl C2 may be secured to their respective cheeks by being rove through and knotted, with the knots drawn into a recess in the inner face, as shown in Fig. 3, or on the outer face, or on top or bottom.

The string G1 is permanently attachedto one end of the cheek D2. It extends out through the end thereof, and is"rove, first, through the eye H, and then through the orice in the adjacent eud of the cheek, D1; thence it follows along the groove d2, and is passed through the hole d* in bot-h cheeks. The other string, G2, is correspondingly applied at the other end of the clamps, being permanently fastened to the cheek D1, and rove through the eye and orifice, and finally rove through the holes d. It follows that the clamps D1 D2 will be closely and strongly held together, thus closing the central and main portion of the bag-mouth, and that on drawing the strings C1 G2 the flexible material of the bag will be gathered at and near each end of the clamps, thus eifectually stopping the mouth of the bag and forming the proper handles for manipulating it at the upper corA ners. On untyin g the knot G3, into which the strings (ll O2 are tied, the fastening is liber zles instead of one large one. This will allow my strings Gl C2 to be received in the crotch between the two nozzles. In cases where this provision shall not exist I can remove, or without much trouble draw out, the ends of strings from the holes d, and thread them through again to retie the bags.

Modifications may bey made. The cheeks may bemade of sheet metal, hollowed on the inner face, and liberally punched with small smooth holes to facilitate the` sewing of the bag material thereto. The bag may be glued or otherwise cemented to the cheeks, either Valone or in addition to the stitching or other fastening; but l prefer the riveting described.

The loose ends of the cords Cl G2 may be simply knotted when it is allowable to keep them always in the hole dl. When it is necessary to remove them at each operation their ends should be left small and properly fitted, in order to equip them for ready removal and rethreadin g in the holes d.

I believe it practicable to make the holesdl not in the center of each cheek, but much nearer one end than the other. This may allow my bags to be used with the ordinary elevator-nozzle without any special provision and without disconnecting' the strings.

The invention is eminently adapted to rough and rapid handling in Steamship work. The rigid parts are too short to interfere with the stowage when the bags are hastily rolled or otherwise compressed together, or placed many bags in one, for the return passage. The bags may be handled, if desired, by seizing directly on the clamps; butthe fastening provides for the accustomed means of handling by the gathered material at the corners. Repairs may easily be made by ordinary workmen.

Instead of sewing the guide-rings on the outside of the bag, they may be recessed partly orentirely into the material of' the bag; or the function may be performed by suitable small holes through the material of the bag, not large enough to allow the escape of the grain. In such case the holes should be worked or defended with a grommet or eyelet.V

The strings, in running along from the end to the middle or crossing-point in each clamp, may be grooved in the bottom or top or on the outside, or in some cases, perhaps preferably, on the inside, between the material of the bag and the strap. The vholes d1, through which the strings Gl C2 are passed in oppositedirections,may, instead of being large enough to take both strings, be two separateA holes close together.

The bags fitted with my attachments will -dump or empty their contents with greater rapidity than sewed bags, there being no stitches to impede the free iiow of the grain, so soon as the strings are loosened.

I claim as my inventionl. The perforated and grooved stripsD,l D2, of rigid material, with the projecting spurs D3 and receiving-recesses d, and the strings Cl (l2, combined and arranged for joint operation, as and for the purposes herein specified.

2. A grainbag having the strips D! D2, locking-spurs D3, and recesses d, and rings or string-guides H, and the strings C102, whereby the mouth of the bag is confined at will, and at the same time lugs or ears are gathered by the act of fastening at each side of the top of the same, as herein specied.

In testimony. whereof I have hereunto set my hand this 31st day of October, 1878, in the presence of two subscribing witnesses.
