SEALENG MEANS FOR ENVELOPS, 81.0.
SPECIFICATION forming part of Letters Patent No. 788,029, dated April 25, 1905. Application filed June 13,1904. Serial Nu. 212.422.
1'1) all whmn it may concern..-
Be it known that I, BENJAMIN R. DYER, a subject of the King of England, residing at Hobart, in the State of Tasmania, Australia, have invented pew and useful Improvements in Sealing Means for Envelops, of which the following is a specification.
-My invention relates to certain new and useful improvements in sealing means for envclops or other receptacles of like character, and has for its object to provide an envelop that may be quickly, easily, and securely sealed and at the same time one which cannot be opened or tampered with without detection.
More particularly, my invention relates to that class of envelops which are fastened in the usual manner and then sealed by means of a tab or other form of counter-seal, so that in the event of tamperingwith or opening the main seal the counter-seal will become mutilated or broken.
\Vith these and other objects in view I have constructed the novel device illustrated in detail in the drawings forming a part of this specification, which I will now fully describe, referring to the said drawings, like characters of reference indicating like parts.
Figure 1 is a plan view of my improved envelop unsealed, showieg the main sealing-flap, the means for opening' the envelop secured thereto, and-the tab or counter-seal. Fig. 2 is a view in detail of the tab and the means for fastening the same to the envelop. Fig. 3 is an enlarged vertical cross-sectional view through the line .1: .1'. of Fig. 1, showing the various parts of the envelop as they will be disposed when the same is sealed. Fig. 4 is a plan view, partly broken away, showin g the curl-lop sealed and the locking means in dotted lines.
a designates the body of an envelop of the usual construction, comprising the side flaps l and 2, sealed one over the other, the rear 3, and the main sealing-flap -1, gumrncd along its outer edge, as indicated at E sealing-flap.
I the cross-head 15, provided in the tab.
one of which strips, in this instance strip 8, the end 7 thereof projects, so that when it is desired to open the envelop in the proper manner the latter may be seized and drawn upward thereby severing the main sealingflap 4 from the body of the envelop and permitting ready access to'the contents. The other end, 10, is gummed to the inner surface of the body A, as is shown in the dotted line of Fig. 'l. Arranged upon the adhesive surface 5 and at a point central thereof is a pronged hook 11, which has its ends passed through respective slitted openings therefor and then bent over upon the inner face of the flap 4, so that the pronged end overlaps the blunt end of the said hook.
The rear sealing-flap 3 is provided with parallel longitudinal slits l3 and 14 of equal length throughout, within which slides a metallic cross-head 15, carrying the auxiliary sealing-tab 16, the latter having formed therein a longitudinal slot 17. Thetah 16 may be used either with or without a. gummed inner face, although to secure the best results 1 prefer the latter method.
In Fig. 1 the full lines represent the envelop unsealed and the dotted lines represent the same sealed. In the dotted lines the crosshead 15), carrying tab 16, is represented as drawn downward to thelimit of itsmovemcnt between the overlapping ends of the hook 11, a locking engagement between the hook and the tab being thereby effected.
\Vhen it is desired to seal the cnvelop the tab 16 is slid to the termination of its upward movement, the main scaling-flap 4 is folded down over the flaps 1, 2, and 3 and the tab 16, the hook carried by the said flap passing through the slotted opening 17 and engagli rlig ic latter is then drawn downwardly to the termination of its movement and the fiap after this operation securely fastened by means of the adhesive coating These slits 13 and 14 thus serve as guides for the cross-head 15 in its vertical movement. \Vhen the flap 4 is sealed, any niovernentof the tab 16 to unlock the same from the hook 17 will be impossible, the latter is securely held by that portion f the axhesive surface ifhafi com-as in mm f ted 2 tact hevewii h :1 case any we mm or Wad. (2 2- 5 in ether wise campers wiih the enveiop 2114; book 11 will tear the cross-head 15 from pesition on me tab 16 and from wifihin the slits 1.3 and 1%, thereby mutilating'he flap 3 03', the book 11, as the case may be, will 5e Eatten so that det ecticn W221 be readily insured.
in .additiofi to fibeadvantages described above improved davice can applied as tbs; faszening means pwkets, WHEEL, Eegai docgmenils, and the 1ike,aiihough E havefhown it iiithe drawings as appiieii an envelop, gonsidering thatmethod one which may be most easiiy undex'st-ocd.
It win he readiiy apparent tmt minor changes be mafia withouz demrting *i a'mn the general spirit of invention.
I am aw'ar that? it is not new in 31 (wide an envelop with a main and auxiliary sealing means for the purpose described, and I not claim the same bmadiy; but
' 'W'hat 1 do giaim, and desire is secure by Letters Eatent', is
1. An enveiop cemprising; a body pox-50m, main, rear and side seaiing-fi ps carried thereemi 0 f I 7,. -A mam, mm: and seaiing fia-ps there by, the mam flap being fovme i with madmszve surface mad carrying E1001; 11-;- a point cents-a1 thereof, the rear seaiingflap being pwvided with imlgitudinal slits; av cross-head sfidiabiy secured Wifihn the siits am; a tab carried thereby, said tab baing pwvide'd with iongiludimfi 510%, the said hank being adapted as engage he cross-head, farmer passing through the said 316%,.
3. An envelop comprisizlg bawdy par bien, main, rear and side sealing flzips married. thereby, the main fiapi formed with amadhesurface and carrying 21001-1 81min thereof his tab segm'ed within the ram s afiingy adapted have we and thezeo'f by the hook.
