APPLICATION HLED 1ULY13,19I5- Patented Oct. 10, 1916.



Specification 01. Letters Eaten Patented a. '10, 191

I Applicationfiled July 13, 1915. Serial No. 39,594.

To all whom it may concern Be it known that I, JACOB J. KLEIN, a citizen of the United States, residing at Kearney, in the county of Buffalo and State of Nebraska, have invented certain new and useful Improvements in Envelops, of-which the following is a specification.

This invention relates to envelops andhas as its object to provide an envelop which I 10 may be readily and quickly opened without the use of a paper knife or letter opener and without the necessity of tearing the end of the envelop. piece by piece.

Another aim of the invention is to provide an envelop which, when opened, may be employed as a filing envelop and will present a neat appearance and be free from n asightly ragged edges at its open end or $1 e.

A further aim of the invention is to provide for the quick and ready removal of the contents of the envelop after the envelop has been opened.

In the instance of the ordinary envelop pened by means of a paper knife or the like, it is difficult to readily distinguish between. opened and unopened envelops in the mail, where a number are indiscriminately placed in a pile or stack and this frequently results in unopened mail being destroyed along with empty envelops. v

The invention, therefore, has as a further object to provide an envelop which, when opened, may be readily distinguished from 5 unopened envelops.

In the accompanying drawings: Figure 1 is a plan view of an envelop embodying the present invention. Fig. 2 is a-perspective view illustrating the manner in which the 40 envelop is to be opened. Fig. 3 is a similar view illustrating the manner in which the contents of the envelop are to be removed. Fig. 4 isa perspective view of one end of the envelop, the end or marginal portion thereof being also illustrated as being removed or separated from the remainder of the envelop.

Corresponding and like parts are referred to in the following description and indicated I in all the views of the accompanying drawings by the same reference characters.

In the drawings, the envelop is indicated in general by the numeral 1 and the same is formed in both of its walls and preferably near one end with a line of perforations, indicated by the numeral 2. The lines of perforations in the walls extend parallel to-theadyacent end edge-of the envelop and it is that portion of the envelop'lying between the said edge and the said line of perforations which is to be separated in opening. the. envelop, this portion being indicated by thenumeral 3. If desired the walls of the envelop may be weakened in some other manner than by the formation of lines of perforations therein. Each line of perforations 2 is interrupted preferably at a point midway between the upper and, lower edges of the envelop and an incision 4 is formed in each wall of "the envelop, the incision terminating at its ends atthe said line of perforations. In thepresent instance, the incisions l are arcuate and their formation results in tabs 5 projecting from the line of perforations toward the opposite end of the envelop, but if desired, the incisions may be made along lines to form a rectangular tab or in fact, a tab of any desired shape.

Referring now to Fig. 2 of the drawings,

it will be observed that when it is desired to I open the envelop, one end of the portion 3 is grasped between the thumb and forefinger of one hand and the said portion 3 is torn from the body of the envelop along the lines of perforations 2. As the tabs 5 are inte gral with the portion 3, they also will be separated from the body of the envelop and the separation of these tabs from the body of the envelop leaves in each Wall of the body a notch 6 to receive the thumb and forefinger in extracting the contents of the envelop. It will -bereadily understood that by reason of the formation of these notches 6, the contents of the envelop may be readily extracted, particularly if the paper is of such size that, when folded and inserted within the envelop, one lateral edge thereof or the end of the missive'registers with the line of perforations 2. I d

From the foregoing description of the invention, it will be seen that there is provided an envelop which may be readily opened by merely tearing off the portion 3 and that after this portion has been removed, the open end of the envelop will 1 present an even and neat appearance, there by particularly adapting the envelop to'be employed as a filing envelop. It will further be understood, as stated above, that the removal of the portion 3 leaves the notches 11-0- unobstructed so that the thumb and foreenvelop inthe act of extracting the contents.-

' The fact will be appreciated that the line of perforations 2 may be formed parallel to either end edge of the envelop or to either tion ma be opened and the contents thereof remove by. two movements of the hand whereas in opening the ordinary envelop and the present invention will an advertising medium.

removing the contents thereof a considerably greater number of movements are required.

It will also be obvious that the envelop of possess value as Having thus described the invention, what s is claimed as new is:

- 1. An envelop having a marginalportion separable from the remainder of the envelop, the said marginal portion having a tab portion separable therewith and formed by a' continuous incision-in the wall of the 2. An envelop its walls weakened along a line parallel to one edged the envelop, whereby the marginalportion of the envelop may be separated from the body of the envelop, the walls of thepnvelop being formed each with a continuous lncision terminating at their ends at the said weakened linela1 whereby to form notches in the said wa 3. An envelop having a removable marginal portion defined by series of erfora tions, the series being in alinement with each other and the said envelop being formed with a continuous arcuate incision extending between and connecting the adjacent ends of the series of perforations 4.An envelop provided parallel to one margin with spaced lines of perforations, the inner ends of the lines of perforations being spaced apart and their outer ends terminating at other margins of the envelop, the envelop being provided in its walls be-- tween the inner ends of the lines of perforations with an uninterrupted arcuate incision connecting the said innerends of the lines of perforations whereby the portion of the envelop between the lines of perforations and the first mentioned margin thereof may be removed by tearing along a straight line. and without the necessity of following the non-rectilinear line of the incision.
