SEAL.-

Specification of Letters Patent.

Patented Sept. 17, 1912.

Application filed November 29, 1910. Serial No. 594,792.

Be it known that I, Anronso M. Pnnnnao; a citizen of the United States, residing at Richmond, in the county of Henrico, State of Virginia, have invented certain new and;

useful Improvements in Seals; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to seals and its principle object is to provide a seal adapted to secure the flap of an envelop in such a manner that access cannot be had to the con-- tents without destroying the envelop.

Another object of the device is to provide a seal wherein there will be two parts which may be so joined in the operation of sealing that it will be impossible to separate them without destroying the article to which they are attached.

While the principle object is to provide a seal for envelops it will readily be understood that the seal may be equally well applied to a number of sheets of paper so that any tampering with the same may be detected and a third object is to provide a seal of general application for use in holding two or more sheets of paper together.

With the above and other objects in view the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and specifically set forth in the claim.

In the accompanying drawings, like characters of reference indicate like parts in the several views, and Figure 1 is a view showing the seal applied to an envelop and with the cover of the seal removed. Fig. 2 is a longitudinal sectional view showing the seal applied to an envelop prior to sealing. Fig.

3 is a longitudinal sectional view showing the seal applied to an envelop and in sealed position.

The back of the envelop is indicated at 20, and the face at 21 while at 22 is shown the envelop flap.

The seal comprises in general a cap which is constructed from an annular base plate 23 having tongues 24 formed thereon, these tongues being bent upwardly from the body of the base plate and terminating in downwardly opening hooks 25. The base plate is provided with an annular series of openings 26 for purposes hereinafter to be described.

The cover of the cap comprises an imperforate plate the body portion of which is in dicated at 27, and this plate is surrounded by a downwardly extending annular flange 28 which terminates in an upwardly opening peripheral hook 29.

In forming the locking plate, as it is preferably termed, which is illustrated in Fig. 6 there is provided a blank having an 1111- perforate body portion 30 surrounded by a radial series of pointed tongues 31 which, in the completed article, are bent upwardly and form a coronal.

In the form illustrated in Fig. 7, there is provided a blank comprising a body portion 31- having an annular series of V-shaped tongues 32 formed adjacent its periphery by slitting the metal and bending the partially severed tongues upwardly to form a coronal similar to that shown in Fig. 2.

In the application of the device the looking plate is slipped inside of the envelop and the points of the tongues on this plate forced through the paper. The flap of the envelop is then pressed down over these tongues and the points forced through the flap. On the tongues which now project through the flap, the base plate is positioned in such a manner that these tongues pass through the apertures 26 therein. The tongues are now manually bent downwardly upon the base plate until they assume the position shown in Fig. 3. Finally the cap is pressed upon the base plate until the hook of the cap springs into and lockingly engages the hooks of the base plate, as clearly shown in Fig. 3. It is now clear that by reason of the cap lockingly engaging the base plate that access to the tongues of the locking member for straightening the same is posltivelv prevented.

The tongues it will be noted after once being manually bent in position cannot be again straightened without destroying the seal cap and mutilating beyond repair the envelop during this operation.

It is obvious that the effects will be. the same whether the form of locking member shown in Fig. 6 or that shown in Fig. 7 is employed.

There has thus been provided a simple and eflicient device of the kind described and for the purpose specified.

What is claimed, is

A three-piece seal including a cap formed of a base member and a cover member having marginal interfitting portions which spring into locking engagement upon the members being pressed together, said base member having a concentrically arranged circular series of openings, and a locking plate having a continuous series of pointed locking tongues adapted to be passed out wardly through the back and flap of an envelop, thence through said openings and into said cap, and finally clenched radially upon the inner face of said base member with a resultant clamping of the sealed portions of the envelop between said base member and said plate.

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