GEORGE ZERBE, OF TIOSA, INDIANA.

ENVELOP.

Specification of Letters Patent.

Patented July 9, 1918.

Application filed October 20, 1917. Serial No. 197,704.

To all whom it may concern:

Be it known that I, GEORGE ZERBE, a citizen of the United States, residing at Tiosa, in the county of Fulton and State of Indiana have invented certain new and useful Improvements in Envelops, of which the following is a specification.

This invention relates to envelops such as are used in railroad work for transporting despatches between various departments in an office or between various ofiices, requiring no sealing.

This invention contemplates for an object the reinforcing of the scam in the rear face of the envelop where the greatest wear is caused in opening the envelop for the extraction or replacing of its contents.

Another object of the invention contemplates the provision of an envelop which may be manufactured without an appreciable increase in cost over the style now universally used.

With these and other objects in view the invention consists in the construction, combination and arrangement of parts as will be hereinafter fully described and claimed Reference is to be had to the accompanying drawings forming part of this invention, in which like characters of reference indicate corresponding parts throughout the several views, and in which:

Figure 1 is a rear view of an envelop showing the application of this invention,

Fig. 2 is a fragmentary view of an envelop showing detail construction of the reinforcing member, and

Fig. 3 is a view on the line 3-3 of Fig. 1.

It is the general practice in oflices where it is necessary to transport despatches from one department to another, and in certain businesses from one building to another, not to seal the envelop, but merely to send it in a packet with others securely bound by a suitable binder. When taking the envelop to remove its contents the operator pulls the back flap away from the front face, causing considerable strain to come upon the joint formed by the rear andcend flaps, making the life of the envelop extremely short.

In order to overcome this disadvantage and to increase the life of the envelop,v I

have devised a reinforcing means, forming an integral part of the envelop thus reducing the cost of manufacture to a mini mum.

In the drawings 5 indicates the rear flap of an envelop, 6 and 7 the end flaps, 8 the sealingflap and 9 the front face thereof. Each of the end flaps has the free corner extended as at 10 to provide an ear to be folded over the outside of the flap 5 and firmly held in this position by a suitable adhesive applied to the adjacent side of the car 10. Although I have suggested the use of adhesive to secure the ear to the rear of the envelop, it is to be understood that any suitable fastening means, such as an eyelet or the like may be utilized, but the use of such means would of course increase the cost of production of the envelop. The cars 10 are folded somewhat obliquely with respect to the upper edge of the back of the envelop so that the connection formed between the ends and the back may be squarely covered eliminating the possibility of the ear becoming severed in the manipulation of the envelop.

The advantages resultant upon the use of my invention will be manifest to all who are conversant with the inconvenience of the devices heretofore used in the art. Such changes as are permissible by the subjoined claims may be resorted to without sacrificing any of the principle or departing from the spirit of my invention.

Having fully described my invention what I claim as new and novel is:

An envelop of the usual form having the free corners of its triangular end flaps provided with extensions having one of their edges parallel with one edge of the end flap, and said extensions extending at substantially a right angle to the upper edge of said flap, being adapted to be folded obliquely over the corners of the back flap for reinforcing the seams between the end flaps and back flap.

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

GEORGE ZERBE.
