WILBUR J. RINGER, OF NE'WBERRY, SOUTH CAROLINA.

ENVELOP-SEAL.

Specification of Letters Patent.

Patented J an. 6, 1914.

Application filed March 8, 1912. Serial No. 682,491.

To all whom it may concern Be it known that I, WILBUR J. RINGER, a citizen of the United States, residing at Newberry, in the county of Newberry, State of South Carolina, have invented certain new and useful Improvements in Envelop- Seals; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in seals for envelops or the like.

An object of this invention is the provision of an envelop seal which is so constructed that the closing flaps will be locked to the lower flaps and held against any unsired displacement.

A further object of this invention is to improve and simplify devices of this character, rendering them comparatively simple and inexpensive to manufacture, reliable and eflicient in use and readily operated.

A still further object of this invention is the provision of a keeper member for the latch in the envelop fastener which by reason of its construction and disposition will act at once as a keeper for said latch and as clamping jaws for maintaining the several flaps of the envelop in secure assembled relation.

WVith the above and other objects in view, this invention resides in the novel features of construction, formations, combinations and arrangements of parts to be hereinafter more fully described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 is a rear elevation of an envelop having my invention applied thereto and showing the closing flap in open position. Fig. 2 is a transverse sectional view showing the envelop in its closed position. Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2.

Referring to the accompanying drawing by similar characters of reference throughout the several views, the numeral 10 designates generally an envelop which comprises the usual body portion 11 having formed upon its end edges the end flaps 12 and upon its lower edge a bottom flap 13 which is secured to the said end flaps 12 in the customary manner. The usual closing flap 14 is formed upon the upper edge of the body portion 11 and is adapted when in its closed posit-ion to overlap the upper edges of the flaps 12 and 13. A plate 15 is secured to the outer side of the flap 13 and is provided with a central opening 16 of elongated formation which registers with the slot 17 formed in the flap 13. The plate 15 is formed with slots 18 arranged in spaced relation from the ends of the said plate and from the opening 16, for the reception of locking tongues 19 formed upon the opposite ends of a rectangular casing 20 which is thus securedto the said plate 15.

It is readily seen that by the placing of the plate 15 on the outer side of the flap 13 and the casing 20 on the inner side and the projection of the looking tongues 19 through the slots 18 of said plates 15 will act as clamping means for maintaining the flaps 13, 1212 in fixed assembled relation.

In order to prevent any undesired displacement of the plate 15, a strip 21 is secured to the under side of the flap 13 and to the rear side of the plate 15 and casing 20. A strip 22 of resilient material is secured to the inner side of the closing flap let as indicated by the numeral 23 and this strip 22 is off-set as at 24: to produce a finger adapted when the flap 14 is in its closed position to pass through the openings 16 and 17. The free terminal of this finger is bent backwardly at an angle to produce a resilient locking barb 25 the extremity of which is spaced a distance from the finger greater than the width of the slots 16 and 17 to provide a means whereby when the finger is passed therethrough the barb 25 will prevent any removal of the same thereby locking the closing flap in its closed posi tion.

It should be understood in this connection that various minor changes in the details of construction can be resorted to within the scope of the appended claim without departing from or sacrificing any of the advantages of the invention.

From the foregoing disclosures taken in connection with the accompanying drawing it will be manifest that a device of the nature described is provided which will fulfil all of the necessary requirements of such a device.

, Having thus fully described this invention what I claim as new and desire to protect by Letters Patent, is:

The combination with an envelop provided with a bottom flap and a closing flap;

of a plate secured to the inner side of the bottom flap, said plate and bottom flap being provided with registering openings and the plate being further provided with spaced slots adjacent its ends, a rectangular casing provided With looking tongues extending through said slots to secure the easing to said plate, a strip secured to the underside of the plate, casing and bottom flap, end a latch member mounted on the closing flap and arranged to enter the openings and lock the closing flap and bottom flap together.

In testimony whereof, I a-fl ix my signature, in presence of tWo Witnesses.

WILBUR J. RINGER.
