S1EC1FICATION forming part 0f Letters Patent NO. 611,445, dated September 27', 1898. Application filed November 8, 1897. Serial No. 657,8()5. (No model.)

T0 all whom t may concern:

Be it known that I, CHARLES V. CAsTER, a citizen of the United States, residing at Siloam Springs, in the county of Benton and State of Arkansas, have inventedv certain new and useful Improvements in Box-Fasteners; and

4I do declare the following to be a full, clear,

and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has relation to box-fasteners; and the object is to provide a simple, strong, and inexpensive fastener of this character.

Vith this obj ect in view the invention consists in certain features of construction and combination of parts, which will behereinafter fully described and claimed.

In the accompanying drawings, Figure lis a perspective view of a box, showing my improved fastener applied. Fig. 2 is an end view, the cover being swung back. Fig. 3 is a similar view with the cover in place and locked. Fig. 4 is a front view, and Fig. 5 is a perspective view showing my fastener attached to a box of different construction.

In said drawings, 1 denotes the box, and 2 the cover.

The fastener consists of two spring-arms a, having eyes b at their upper ends. The springarms are secured to the front side of the box by rivets or staples, as shown. A loop c is pivoted in the eyes of the spring-arms and has crank ends d, upon which is hung with friction contact apbail c, having a detent or toe f, adapted to the staple g, secured to the front edge ofthe cover of the box.

In operation when it is desired to lock the box the front end of the loop is elevated, which will throw the bail from the inclined position shown in Fig. 2 to a vertical position and the toe or detent directly above the staple. When the toe or detent reaches this position, the loop extends at right angles to the front side of the box, and by pressing it upwardly its cranked endsare moved downwardly, thus drawing the detent or toe into the staple of the cover, in which position the cranks are ata dead-center. The point f of the springloop is then pressed under the staple of the cover and is held in this position by the spring in the sides of the loop.

If desired, a wire with a seal may be wound about the bail and loop.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, s-

The combination with a box and its cover, of a fastener composed of spring-arms having eyes at their upper ends and secured to the side of the box, a loop having cranks, said loop pivoted in said eyes, and a bail pivoted to said cranks and provided with a detent or toe, and a staple secured to the edge of the box to receive said detent or toe, the construction being such that when the loop is depressed the detent or toe will be disengaged from the staple and thrown forwardly, and when the loop is elevated and pressed inward, the detent or toe will be thrown inward and be drawn down vertically into said staple, substantially as set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
