Description
MAX MANUEL BEROLZHEIMER, 0F NEW YORK, N. Y.
Letters Patent No.` 102,211, dated April 26, 1870.
IMPRO VEMN T IN ENVELOPE-FA'STENERS.
The Schedule referred to in these Letters P'atent and making part of the Barre To all whom il may concern.-
Be'it known that I, MAX EMANUEL BnnoLzHnr- MR, of the city, county, and State Ot' New York, have invented a new and useful Envelope-Fastener;- land I hereby declare t lat the. following is a full, clear, and exact description thereof, reference being had to the accompanying drawings making a part ot' this specilicatiou, and the letters of reference marked thereon, in which the saine letter represents the same thing in each figure.
The object of my invention is to secure envelopes and other articles made of paper or other material, capable ot' easy perforation, from being opened and liavility toabstraetion of contents without detection.
Figure 1 is a plan of the exterior disk.
Figure 2 is a plan 0t` the interior disk.
Figure 3, a side view thereof.
Figure 4, an envelope with the disks attached.
Figure' 5 is a cross-section ot' the exterior disk.
A 'relin'esents the exterior disk of the fastener;
B, the interior disk;
C C, the teeth ot' the interior; alu
D D, the holes corresponding therewith in exterior disk A.
The operation is ns follows:
Place disk B beneath the under surface of an euvelope, so that each tooth will come within-one otl the four divisions, and press them suttlciently upon the teeth, to insure perforation.
Place disk A upon the elastic teeth, and by aslght lt will be seen that, owing to the peculiar l'orm and construction ot' the exterior disk, when the two disks are applied to an envelope 4and attached together, as described, the teeth are entirely concealed, and cannot be reached foi' the purpose ot' det-aching them fronrthe exterior disk, without cutting or breaking the metal ot' said exterior disk.. t
What I claim, and desire to secure by Letters Patent, is-' The fastening device described, consisting ot' two parts A B, one toothed and the other correspondingly perforated, constructed substantiall y as described, and to operate together as and for the purposes specified.
MAX E. BEROLZHEIMER.
Witnesses S. J. GORDON, WM. T. WILLIS.
