SAFETY-SEAL FOP ENVELOPS;

Specification of Letters Patent.

Patented July 25, 1905.

Application filed June 1, 1904. Serial No. 210,745.

To aZZ whom it may concern.-

Be it known that 1, 101mm JAMES HALLO- RAN, a citizen of the United States, residing atBaltimore, State of Maryland, have invented new and useful Improvements in Safety-Seals for Envelops, of which the following is a specification.

This invention relates to a' safety-seal for envelops to be applied to the back thereof where the several flaps meet, the object being to prevent an envelop from being opened without wholly or partially destroying the seal or mutilating it to such an extent that a casual inspection of theseal will show whether the envelop has or has not been tampered with. The seal may also be used for packages and parcels of various sorts, as well as with envelops.

In the accompanying drawings, Figure l is a view of the back of an envelop with my improved seal applied thereto. Fig. 2 is a view of the seal.

The seal (indicated by '1) is made of paper, preferably in the shape of a rhomb or diamond, in each edge 2 of which near the points 3 of its longer axis is made a notch 4, formingspear-head-shaped corner portions adapted to lie in the angles between the edges of the bottom folding flaps of the back of the envelop, whereby when an attempt is made to open either flap at either ofits edges the adjacent spear-shaped corner portion will be moved in one direction or the other and causes strain to be transmitted at its weakest portion between the contiguous notches, this causing the seal to be torn or mutilated to show that the envelop has been tampered with. It is desirable, although not necessary, that the seal be of glazed paper. Color, crests, monograms, or other forms of decoration may be placed on the face of the seal, while its back is covered with an adhesive substance.

The seal is to be applied to the back of an envelop or placed on any other package over the closededge of the wrapper, as in Fig. l, in such manner that any attempt to remove the seal will cause it to tear at" the notches, and thus disclose the fact that the letter or package has been opened or an attempt to open it has been made.

Having thus described the invention, what is claimedas new is- The combination with an envelop having triangular top, bottom and side folding flaps, of a safety-seal therefor comprising a body of rhomb or diamond form'ha'ving notches in,

the edges near the points of its major axis,

the notches formingspear-shaped corner por-' tions, said seal adapted to be fixed to the back of the envelop with its body covering the ends of the fiaps at their point of union and with its spear-shaped portions lying in the angles between the fiaps, whereby when an attempt is made to open either flap at either of its edges the adjacent spear-shaped corner portions will be moved in one direction or the other and cause strain to be transmitted atits Weakest portion between the contiguous notches causing the seal to be torn or muti lated to show that the envelop has been tampered with.

In testimony whereof I afiix my signature in presence of two witnesses.
