Specification of Letters Patent.

The principal object of the present invention is to provide simple means of a novel nature for securing the flap of an envelop in closed condition, said means being exceedingly inexpensive being such that they may be expeditiously applied to an envelop, said fastening means moreover being highly effective, and while readily operable, is such that there is little danger of the iiap becoming accidentally released by handling or during transit in the mails.

In the accompanying drawings, Figure l is a plan view of a rear side of an envelop showing the flap fastened by the novel means. Fig. 2 is a longitudinal sectional view on the line 2-2 of Fig. l. Fig. 3 is a detail perspective view of a portion of the envelop showing the flap open. Fig. 4 is a detail sectional -view through a slightly modiiied form of fastening means.

Similar reference numerals designate coi'- responding parts in all the figures of the drawings.

Referring to the embodiment disclosed in Figs. l, 2 and 3, the envelop comprises a body 5, which may be of an f desired shape or character and of any material. The mouth 6 is arranged to be covered by the usual flap 7 and the terminal of said flap is preferably reinforced by being doubled inwardly, as shown at 8, though with heavier grades of material, doubling is not necessary.

he reinforced portion is provided with a single opening or slot 9. Secured to the rear side of the body of the envelop are oppositely disposed overlapping inner and outer tongues 10 and il secured at their outer ends to the rear wall of the envelop body by any suitably means, as for instance, glue. The inner tongue is preferably shorter than the outer tongue, and of less width than the saine, having its free portion tapered toward its rear end and said end being preferably curved or bent inwardly slightly as illustrated in Figs. 2 and 3. The various parts are so arranged that when the flap is turned down to closed position, the inner tongue 10 to manufacture, the parts l may be passed Patented March 9, 1909.

It will thus bc evident, particularly by reference to Figs. 1
