Description

UNITED STATES PATENT OFFICE.
BERTRAND JOSEPH HOFFACKER, OF MELROSE, NEW YORK.
IMPROVEMENT IN ENVELOPES.
Specification forming part of 'Letters Patent No. 90,663, dated June 1, 1869.
To all whom it may concern:
Be it known that I, BERTRAND JOSEPH HOFFACIGER, of Melrose,in the. county of Westchester and State of New York, have invented a new Safety-Envelope; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters otl reference marked thereon, making a part of this specifica-tion.
The nature of my invention consists in an envelope shaped and constructed to close without any adhesive substance, metal pins, plates, bands, or shields, or any other material whatever attached to it.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
Figure l represents the shape of the envelope unfolded, with the two excavations of the side aps, the dovetailed excavation of the lower Hap, and the i'oldings of the top end of the upper or seal Hap. Fig. 2 represents all four tlaps folded and the envelope closed.
The object of my invention is to fasten the aps of the envelope inl a more secure, safe, and ready manner (more ready because of excavations instead of incisions) than is done in the ordinary way, without any adhesive or other substance in order to close it, and thus reducing the cost of its manufacture.
The lower flap, A, has a dovetailed lappet, m. The side ilaps, B B, have an acute-angular excavation, n ot. When these aps are folded the projecting pieces of paper caused by said two excavations are inserted into the opening caused by the dovetailed lappet of flap A, and will pass sidewisc initier the lower flap. The dovetailed lappet is then bent inside, and by that covers and holds the inserted parts of the side flaps.
ln order to secure a more firm hold of the insertion of the two side liaps, I would suggest cuts s s to be made in each, by which that part could be passed under the narrow part of the lower flap, or equivalent cuts to the same effect. The two projecting pieces caused by the excavation a n can also be inserted into two oblique or perpendicular excavations ofthe lower flap, A, dispensing by this inode with the dovetailed lappet, `and simplifying' its manufacture. Another horizontal excavation above or below the inserted side ilaps is made for the insertion of the upper BERTRAND JOS. HOFFAOKER.
