Specification of Letters Patent. Pate ted sig t gj 1920 Application filed May 23, 1919. Serial No. 299,255.
My invention relates to a solid'face, or
oneiece window envelop, of the type shown in S. Letters Patent, No. 835,850, in
I which there is a transparent part on the address, or front side of the envelop, pro-- .duced by applying varnish, or other material upon the envelop blank;
My invention particularly relates to an improved method of making window envelops of-the type above referred to, and my invention consists in my improved method of. making said envelops.
In the ordinary method of making window envelops of the type above referred to, the varnish, or other material, when applied to the envelop blank, to make the transparent part therein, leaves this part of the envqflop blank in a sticky condition, so that 1t is necessary to dry this part before the envelop blank can be folded.
In my improved method of making a window envelop of the type referred to, I apply immediately after the gum for the flaps, and the varnish for the transparent part have been applied to the blank, a separate transparent piece of paper on the inner side of the blank over the sticky varnished part, to cover said varnished part and allow the envelop blank to pass immediately to the folding mechanism to be folded, without waiting for. the varnish to dry.
Referring to the drawing':--
Figure 1 shows a front viewof a window envelop embodying my invention, and made according to my lIIlPIOVdIIltBthOd.
Fig. 2 shows an envelop blank before any operation has been performed thereon.
Fig. 3 shows the envelop blank shown in Fig. 2, after the gum has been "applied to the top, and bottom flaps, and the varnish, or
- other material has been applied to the body portion of the blank, to make the transparent part or window, .and
Fig. 4 shows th blank shown in Fig. 3,
after the transparent piece of paper' has' been 'applied'to the varnished part.
In the accompanying drawing, 1 is the blank from which the envelop is made, which blank may be of any desired shape or configuration. 2, and 3 are the side or end flaps, 4, and 5 are the top and bottom flaps, to which gum 6 is applied in any ordinary way, and on any well known machine for making window envelops. 7 is the transparent part or window, which in this instance is of the usual oblong shape, and is made by applying varnish, or other suitable material upon the inner side of the blank 1. The varnish is preferably. applied to the blank 1, at the same time that the gum 6 is 2 applied. The gum, and varnish may be applied to the inside of the envelop blank, at the picker mechanism of the machine.
The piece of paper 8, preferably of transparent material, Fig. 4, is placed on the inside of the blank to extend over the varnished surface 7. The placing of the piece of paper 8 over the varnished surface 7, and the folding of theblank, may be performed at the plunger mechanism of the envelop machine.
The folding of the blank produces the complete solid face envelop, 9, having the transparent window 7 shown in Fig. 1.
The placing of the iece of paper 8, on the varnished surface immediately after the varnish has been applied to the blank,
forms a covering for the varnish, and'overcomes the necessity of drying the varnished surface prior to the folding of the blank, and revents the flaps from sticking to the varnished surface.
My improved method of making a solid face window envelop may be carried out on any'well known type of machine for making window envelops.
It will be-understood that my improved method of making window envelops of the type above referred to, may be varied somewhat. i I
The gum for the flap, and the varnish for the transparent part, are preferably applied to the envelop blank at the same time, and at one operatlon. The piece of transparent paper 8 is preferably applied to the varnished surface, and the blank folded, to form the complete envelop, at the same time, and at one operation.
Having thus described invention, what T in materiel upon the inner side of the envelop blank, which consists in the application of piece of transparent. peper upon the inside of the envelop blank, toeXtend over and cover the trenspsrent part in the blank.
2. The improved method of making at window envelop, which consists in applying u on the inside of the envelo) blank um upon thelqleps, and varnish or other materiel to form the transparent part or Window, and then applying a piece of transparent paper on the inner side of the blank, to extend over and cover the varnish or other material, and then folding the blank to form the complete envelop.
3. T he improved method of making a Win- (low envelop, which consists in applying gum upon the flaps, and vernishor other
