GEORGE D. BARBER, OF WOlEtCESTER, MASSACHUSETTS.
ENVELOP-FASTENER.
SPECIFICATION forming part of Letters Patent No. 757,716, dated April 19, 1904.
I Application filed December 5, 1903. Serial No. 183,890. (No model.)
citizen of the United States, residing at Worcester. in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Envelop- Fasteners, of which the following is a specificatio'n.
My invention relates to an envelop-fastener for what are ordinarily termed merchandise envelops. In this class of envelops a metallic fastener is ordinarily employed, which is secured to the body of the envelop and is adapted to engage with an opening in the flap, to hold the flap closed, and also detachably connect it with the body of the envelop.
The object of my invention is to provide an improved envelop fastener of simple construction and preferably made of sheet metal and stamped or cutout into the desired shape.
My improved envelopfastener is preferably of flat structure, with a plurality of attaching-prongs to attach the fastener to the envelop proper and a plurality of bendable tongues to extend through an opening in the flap when it s closed and engage the flap.
My lnvention consists 1n certain novel features of construction of my envelop-fastener,
as will'be hereinafter fully described.
Referring to the drawings, Figure 1 shows an envelop with my fastener attached thereto and the flap open. Fig. 2 corresponds to Fig.
1, but shows the flap closed and secured by my fastener; and Fig. 3 shows on an enlarged scale my fastener detached.
I have shown in the drawings the preferred form and structure of my envelop-fastener, which is stamped or out out of thin sheet metal and comprises the body portion 1, preferably of flat structure or surface, with a plurality of attaching-prongs 1" thereon, preferably three, which extend out from three edges of the part 1, (one from each edge.) The prongs 1 are bendable and, are inserted through the surface of the envelop 2 and then bend down or'flattened toward the part 1 and against the inner surface of the envelop to secure the fastener thereto.
From one edge of the part 1 of the fastener and in the same plane therewith extend a plurality of tongues 1", preferably three in numher, which are bendable. The middle tongue 1" is preferably shorter than the other two tongues 1", as shown.
The flap 2 of the envelop 2 has preferably a noncircular opening 3 therethrough of elongated shape. The length of the opening 3 is preferably a little greater than the width of the three tongues 1".
The opening 3 is preferably reinforced by a strip i of paper or other suitable material.
When the envelop is not in use, the tongues 1 lie flat upon the surface of the envelop, but when the flap is to be closed and secured the tongues 1 are bent and inserted through the opening 3 in the flap 2 as the flap is closeddown on the envelop and then two of the tongues 1", preferably the outside ones, are bent one Way down upon the flap and the other tongue 1 bent the opposite Way, as shown in Fig. 2.
By means of the three tongues 1 passing through the opening 3 in the flap 2 and being bent over as described the flap is securely fastened to the envelop and cannot become detached, except by bending up all of the tongues 1".
It will be understood that the details of construction of my envelop-fastener may be varied, if desired.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. An envelop fastener comprising a flat body portion having attaching-prongs projecting from three edges thereof, by which it is secured to the envelop, and three bendable tongues extending from one edge opposite one of the attachingprongs,said bendable tongues being of different lengths. 2. An envelop fastener comprising a flat body portion having attaching-prongs projecting from the body portion at three edges thereof, and three bendable tongues extending from one edge opposite one of the attaching-prongs, the intermediate prong being shorter than the other two.
