Application ar a November 2, 1921. Serial No. 512,218.
To all. whom it may concern:
' Be it known that 1, WILLIAM VTILBURGE a citizen of the United States, and resident of Brooklyn, in the county of Kings and 17 1918 to Farron S. Betts, the inner end of each envelope has an inwardly turned fold 22 which interferes with the insertion of a record because the latter is apt to engage the exposed edge of said fold, which then prevents the proper seating of the record in the inner end portion of the envelope and often causes the bursting or tearing of the outer end of the envelope. It is the aim of the present invention to providean envelope without any inwardly extending exposed edges or folds to interfere with the insertion of a record.
Another object is to increase the number of folds of the paper, or. other material froinwhich the envelope is made, along its inner edge, where the binding perforations are formed, so that said increased number of folds will be strong enough to effectually retain the envelope on the binder pins with- I out the necessity of employing the usual reinforcing metal eeyelets in said perforations. Others objects will appear as the description proceeds.
The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification, and then more specifically de fined in the claims at the end of the descrip tion.
In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views:
Figure 1 is a front view of an envelope inade substantially inaccordance with this invention.
'ticallv of said envelope.
Figure 2 a section taken horizontally through the middle of the envelope as shown in Figure 1.
nigure 3 is a plan view of the blank from which said envelopeis "formed, the folds being indicated. in dotted lines.
7 As indicated in Figure 3, the envelope is preferably made of a single piece of paper or other suitable material having portions 1 and 2 for forming the front and back walls of the container, the same being folded upon one another along the dotted line 3. The portion 1 has a flap 4 alongits lower edge adapted to be folded along the'dotted line 5 and secured to the lower edge of the portion 2, as indicated in dottedlines in Figure 1 when the envelope is made upl The upper edges of the portions l and 2 may be notched, as at 6, to permit a recordto be easily withdrawn from the envelope.
Theportion 1 is extended at its'i'nner end for some distance beyond the inner edge of the portion 2, and said extending part 7 is folded into the form of a box-'plait 8 arranged on the rear face of the envelope and having folds 9 and 10 extending ver- The inner edge21 of the portion 2 of the blank extends between the inner side of the outer fold 10 of the box-plait 8 and the adjacent part of the portion 1, and is secured by glue,';or otherwise, to said fold -10'sothat the extremity of said inner edge of the portion 2 extends away from the center of the envelope where it cannot obstruct theentrance of a record as in the Bet-ts construction, here inbefore mentionedw I Theextending part 7 of theportion'l of the blank has a fold 11. arranged on the front face of the envelope which lies opposite to the box-plait 8. The extremity of said portion 7 is fastened by glue, or otherwise to the portion 1 opposite the fold 10 of said box-plait, forming a corresponding lap 12 at the outer edge of the front fold 11. Another fold 13 is formed along the inner edge of the front fold 11 to overlap the fold 9 of'the box-plait. 8. four thicknesses of the material thus being provided along the inner edge of the envelope through which perforations 14: are formed for the passage of the binder pins, not shown. Because these perforations are made through the four thicknesses of material, it is not I lines 15 and necessary to reinforce them with the usual metal eyelets. 1
Referr ng again to Figure 3, the extension 7 at the end of the portion 1 of the blank is vfolded on the dotted lines indicated to form the rear boX-plait 8 and front fold 11.
The fold 10 of the rear box-plait s8 is formed by bending the material along the dotted 16, while the fold 9 of said rear boX-plait is formed bybending the material along the dotted lines 17 and 18. The fold 13 of the front fold 11 is formed by bending the material along the dotted line 19, the extremity 20 of said extension 7 being secured along the lap 12. as already explained. The sidesof the inner portions of the box plait 8 and front-fold 11 are preferably sealed or 'glued'together, but the folds 9 and 13 themselves through which the perforations l4: are formed, are preferably not glued together, as shown in Figure 2.
