ENVELOP.

Specification of Letters Patent.

Patented Inch 31, 1908.

Application filed August 5, 1907. Serial No. 387,116.

" To all. whom it may concern: 1 Be it :known that 1, JOHN W. CARRAWAY, a citizen of the United States, residing at St. James City, in the county of Lee and State of Florida," have invented a new and useful Envelop, oft which the following is a specification. J-

This invention relates to safety envelops. The object of the invention is in a novel and at once practical and ready manner to render it impossible, without detection, to openan envelo with the envelop has been made.

With the above and other objects in view as will appear as the nature of the invention is better understoodythe same consists, generally stated, in providing the lower flap of an envelop with two concentric slots, which may bevcurvilinear or angular, and back of which ispasted a detector, in the nature of a patch of any suitably colored paper bearing thereon any preferred legend, such as the name of the sender, that port-ion of the detector bearing the printed legend being adapted to be attached to the sealing flap,

whereby should the flap be opened, that lportion of the detector adhering thereto wi 1 be torn or disrupted in such a manner as to give ocular and positive evidence that an unlawful attem t to open the envelop has been made. Tlie detector is by preference secured only at its'ends to the envelop, and the second slot is utilized to permit insertion of the blade of a pen knife to cut away the lower and side flaps and thus permit the seal- .ing flap to be drawn backward, whereby an inspection may be made by the recipient or "not, should his suspicions be aroused, the

sealingfiap has been tampered with.

Instead of employing a printed legend upon the'detector that portion which will be attached to the sealing flap may be provided with lines of openings, conforming in arrangement to the contour of the slot, the weakened linesthus provided permitting the ortion that will be attached to the sealing a) to be torn, should the said flap be unlawfull opened.-

urther and more specific details of construction of the invention will be l'lcrcina'fter fully described and claimed.

In the accompanying drawings forming a after it is once-sealed, and. further to-enab e. the recipient of the envelop "to ascertain without destroying the safety "seal, whetheror not an attempt to-tamper by inserting the blade of a pen knife throufh part of this specification and in which like characters of reference indicate corresponding parts, Figure 1 is a view in elevation taken from the rear side of an envelop, dis.- playing the sealing fla turned u ward, and the legend upon the etector.'- Fig. 2 is a similar view taken from the front of the envelop, a portion thereof being exhibited as torn away to display :1" 3 detector. Fig. 3 is a view similar to Fig. l, of a slightly modified -t'e(. tor 6 which is preferably constructed of a thin strip of paper, of any preferred color, and that bears on that portion which will appear through the slot 4 any suitable legenc such as the name of the sender, or the like. Below the slot 5 and on the outer'face of the flap 3 is print-ed the directions Cut out here. As shown in Fig. 1, the detector is pasted only at its end portions 7 to the flaps 2, the intermediate portion being unattached, and the paste lines will be located beyond the terminals of the slot- 5, so that there will be no interference with the knife blade when it is inserted in the said slot for the purpose of cutting away parts of the pered with.

As shown in Fig. 2 the lower wall of the slot 4 will register or aline-with the center portion 8 of the flap 1, care being taken in sea-ling theenvelop that the ortlon 8 does not overlap the said slot wa 1. "When the sealing flap is attached in the usual manner, that portion of the detector under the slot 4 will adhere to the flap so that should an attempt be made to open the envelop said portion will be detached or mutilated insuch manner as to give positive proof that the envelop has been tamperedwvith. Should the recipient have a suspicion that an attempt has been made to o en the envelop, it will only be necessary to (eternnne this act the slot 5 and cut away those portions of t 1e flaps 2 and 3 to which the detector isattached and then turn the sealing fiap backwards or to the position shown in Fig. 1, whereby ready inspection of the detector may be secured.

In the form of invention shown in Fig. 3, instead of having that portion of the detector under the'slot 4 homogeneous, it may be weakened by rows of erforations 9, so that the field definedby t e openings may readily be detached from the remainin portion of the detector when the sealing ap is opened. To inspect this form the same procedure as thatabove described, will be observed. v

From the foregoing description it will be seen that although the improvements herein defined are simple in character they will be positive in securing the results designed, and further that to adapt the improvements to envelops' already made will require no other change in their structural arrangement than the provision of the

slots

4 and 5.

What is claimed is 1. An envelop having one of its flaps provided with a lurality of slots and a detector arranged baclz of the slots and having its end portions only attached to the envelop.

'2. An envelop having one of its flaps pro- 3mm. 1, v

vided with a urality of slots, and a detector arranged bacl; being so positioned as that one Wall thereof will conform to the line'of the sealing flap.

3. A11 envelop having one of its fla s provided with a plurality of concentrica y disposed slots, a detector of readily disruptible material secured at its end portions only back of the slots, that ortion of the detector under one of the legend.

4. An envelop having one of its flaps provided with two slots, and a detector secured at' its ends back of the slots, the intermediate portion of the detector be ng unattached to permit insertion of a pen knife blade for the purpose of separating those portions of the envelop to which the detector is attached for the-purpose of permitting inspection of the detector.
