WILLIAM MASTERS, OF KANSAS CITY, MISSOURI.

REVERSIBLE ENVELOP OR WRAPPER.

SPECIFICATION forming part of Letters Patent No. 700,352, dated May 20, 1902.

Application filed June 22,1901. Serial No. 65,581. (No model.)

To all whom it may concern:

Be it known that I, William Masters, a citizen of the United States, and a resident of Kansas City, in the county of Jackson and 5 State of Missouri, have invented new and useful Improvements in Reversible Envelops or Wrappers, of which the following is a specification.

My invention relates to fastening devices to for reversible envelops; and the object of my invention is to produce a double fastener or one having two tongues which are inserted together through the eyelets in the flaps and are then bent flat in opposite directions for 15 securing the flaps in closed position.

I will now proceed to describe my invention with reference to the accompanying drawings, in which—

Figure 1 is a perspective view of an envelop 20 constructed according to my invention. Fig.

is a plan view of the envelop unfolded. · Fig. 3 is a detached view of the form of fastener shown in Figs. 1 and 2, the fastener being unbent or flattened out. Fig. 4 shows two edge25 wise end views of the envelop, the fasteningtongues being extended in opposite directions in said views.

As shown in Fig. 2, this envelop comprises a central portion 3 for the addresses, two end 30 flaps 4 and 9, and two triangular side flaps 6 6. All of said flaps may be folded against either face of the central portion 3 upon the dotted lines in Fig. 2. One of the end flaps 4 and the side flaps 6 6 are each provided with 35 an eyelet 7, and said eyelets are so located that they register, with one another when the flaps are folded together. In the other end flap 9 a semicircular cut is made, as shown in Fig. 2, and the semicircular flap 10 formed 40 by said cut is folded back upon the flap 9, forming an opening 8. A flexible metallic fastener 5 has a foot portion 5', which is held between flaps 9 and 10, while its two tongues 5 project through an opening in the fold of 45 flap 10, which is glued or pasted to the flap 9, thereby retaining”the fastener securely in position in a simple manner. In either direc tion in which the flaps of the envelop are folded (the flap 9 being folded first and one of flaps 6 last) the tongues may be inserted 50 through the three eyelets 7, as shown in Fig. 1, and then bent flat, thus securing the envelop. Fig. 4 shows the tongues 5 as bent ¹outwardly from either side of the flap 9. The address of the sender maybe printed on one 55 side of the central portion 3, while the opposite side thereof is left blank for the name of the addressee.

The above-described construction may be applied to wrappers as well as to envelops by 60 making all of the flaps of sufficient length and width to pass around the package and have the eyelets register with the fastening device.
