SPECIFICATION forming part of Letters Patent No. 405,518, dated June 18, 1889. Application filed February 12, 1889. Serial No. 299,588. (No model.)

To aZZ whom it may concern.-

Be it known that I, ROBERT WILsoN, of

Grubville, in the county of Jefferson and' The invention consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure -1 is a perspective View of the improvement as applied. Fig. 2 is a perspective view of the improvement in an open position. Fig. 3 is a plan view of the improvement in a closed position and with parts in section. Fig. l is a plan view of a modified form or: the improvement. Fig. 5 is a side elevation of another modified form of the improvement, and Fig. 6 is a plan view of the same.

The improved bag-fastener is composed of the members 0 and D, lying side by side in the same plane and hinged together at one end by a link E. The inner corners of the members-that is, the portions lying between the opposite cross-bars e of the link E when the parts are in the position shown in Figs. 1, 3, 4, and 6-are rounded off, as shown at 0 (Z. Each of the members 0 and D is provided at its inner edge with a curved recess 0 or D, respectively, as is plainly shown in Figs. 2 and 8. A rod F passes transversely and loosely through a corresponding aperture (-1 in the free end of the member 0, its outer end being bent at right angles to form a hook or collar F, which prevents the rod from being pulled out of the members. The rod F is provided on the opposite end from that having the hook F with a ring F adapted to pass, with part of the slot D formed in the front end of the member l).

When the members 0 and D are closed, as shown in Fig. 3, the ring F is on the front rod F, through a longitudinally-eXtending 5o edge of the member D, so that when the op- 5 5 erator takes hold of the said ring F and gives it a quarter-turn said ring Wlll stand at right angles to the slot D and the two members 0 and D will be locked in place in a closed position.

When the device is to be applied, the fastcner is in an open position, as illustrated in Fig. 2, and the mouth of the bag is then folded up in the usual manner, after which the members 0 and D are placed around the folded part, which extends between the curved recesses O and D. The free ends of the members C and D are then pressed firmly toward each other, so that the rod F, with its ring F passes through the slot D after which the operatorgives the rod F a quarter-turn by taking hold of the ring F as before described. The bag fastener is then looked in place on the mouth of the bag and effectively closes the same.

The bag-fastener is quickly removed by giving the ring F .a quarter-turn, so as to place it in line with the slot D of the member D. The two members C and D can then be swung apart and removed from the mouth of the bag.

In the modification shown in Fig.4 the rod F is replaced by a link H pivoted on the member 0 and passed over the front end of the member D to engage a notch H in the latter.

In the modification shown in Figs. 5 and 6 the rod F is mounted to turn in the member 0, and is adapted to pass into a recess D formed in the front end of the member D. The rod F is then turned so that the ring F stands vertically and engages a notch D in the front edge of the member D.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The herein-described bag-fasten er, comprising two fiat members 0 D, lying in the same blame with their adjacent edges recessed and member and locking the front end of the 0p their inner rear corners rounded, apertures posite member thereto, substantially as set being formed in their rear ends, the rectforth.

tures to connect the two members, and a MALETA DENNY,

fastening turning on the forward end of one JAMES P. KEE.
