PACKAGE.

SPECIFICATION forming part of Letters Patent No. 571,928, dated November 24, 1896.

Application i'lled May 7, 1896. Serial No. 590,540. (No model.)

To all whom t may concern:

Be it known that I, GURDoN PENDLETON, Jr., a citizen of the United States, residing at Carbondale, Lackawanna county, Pennsylvania, have invented a new and useful Improvement in Packages, of which the following is a specification.

This invention relates mainly to means for securing the covers of sheet-metal, glass, and other cans or packages in place, so that the cover will be water-tight, and may be readily applied or removed, and the particular obj ect of my invention is to provide a covering device for this purpose which can be applied and removed with unusual facility, is absolutely tight, is of exceedingly simple and strong construction, is applicable to nearly all varieties of packages,and renders the package extremely portable and easily packed.

In accordance with my invention I form the cover of the package with an expansible rim to fit within the mouth of the package, and by a simple dished plate expand said rim radially against the Wall of the package, so as to tightly seal the package, the expanding device acting when reversed to permit the contraction of the rim and the ready removal of the cover.

In order that my invention may be clearly ascertained, I shall iirst describe in detail the manner in which I carry my invention into practice, and then point out its novel features in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which like parts are designated by the same letters in all the figures.

Figure l is a cross-sectional view of a package embodying my invention, the cover being in place, but not sealed. Fig. 2 is a sectional plan view of the same on the line 2 2, Fig. 1. Fig. 3 is a sectional plan view on the line 3 3, Fig. l.

A designates the body of the package here illustrated, which may be of tinned iron or other flexible material or glass or other unyielding material, and which I, in this example of my invention, form with an internal corrugation or groove B a short distance below the upper edge and with a laterally-projecting rim or shelf C at its upper edge. I prefer to make the cover D for the package of sheet metal and to construct it with a bottom plate E, formed integrally, as ina die, With a depressed shoulder F, forming a channel around its edge, and with a yielding rim G to fit snugly within the upper end of the body A of the package, the rim G being also formed with an outwardly-projectin g horizontal rim H to iit and rest on the shelf C of the body and with an upwardly-projecting flange I. I also prefer to construct the cover D with a centrally depressed or dished top plate J, the edge of which rests on the rim H of the bottom plate and is secured thereto by having an upwardlyprojecting flange K, over which the angeI of the bottom plate is tightly bent. An exceptionally stiff cover is thus formed for the package, the riin G of which fits and is overlapped by the upper end of the body A of the package.

To seal and secure the rim G and thus the entirecover to the bod yA, I employ a device for expanding the iiexible rim G against the overlapping part of the body, and, when the same is provided with the groove B, into said groove, and I prefer to employ for this purpose an upwardly-dished plate L, which is composed of two plates radially slotted to allow the attening and consequent peripheral expansion of the plate L, the slots in one component plate being covered by the unslotted portions of the other component plate. I fit said dished plate L on the bottom plate E of the cover before the top plate J is secured thereon, so that its edge will bear against the inside of the rim G opposite the groove B, if

present, and will restV upon the depressed shoulder F as a fulcrum, so that bycentrally depressing or attening the dished plate L the periphery of the same will expand the yielding rim G evenly and tightly against the body of the package and into the groove B, thus eecting a perfect joint. For eecting this depression of the dished rim-expanding plate L and for releasing the saine so that the cover can be Withdrawn from the body I prefer to employ a screw M andrto form the top plate J integrally with a struck-up threaded extension N, in which the screw M turns and works against the rim-expanding plate L, the downward dishing of the top plate J serving to more eectually resist the consequent upward strain on the screw M and extension N.

ICO

I prefer to attach said cover securing and releasing screw M to and operate it by a handle O, which I prefer to employ also as the bail of the package, and to this end I provide the screw M with a head P, which I construct of a lower plate Q, formed, as in a die, with the said depending hollow screw M and an upwardly-projecting rim R, and of an upper plate S, formed with a downwardly-projecting rim S', which is fitted within the rim R and is secured therein by turning over the rim R, as shown. To this head P, I attach the handle or bail O by bending the ends of said bail and extending them inward through overlapping reversely-semicircular apertures T in the overlapping rims Rand Suntil they meet over the hollow screw M, whereIcouple them by means of a clip U, dropped over the said meeting bail ends and fitting within said screw. Vith this construction the bail O can be readily used to apply and secure or release and remove the cover, and can be folded down around the head P within the bent bodyfiange I, so as not to interfere with the close packing or storage of the package.

I claim as my inventionl. rPhe cover for a package herein specified as comprising a sheet-metal cover-plate E, formed integrally with a rim Gto iit the mouth of the package, a dished expanding-plate L Within the rim G to bearradially against the same, and means for attening the dished plate L toward a plane and holding it flattened.

2. The cover for a package herein specified as comprising a cover-plate E formedwith. a cylindrical sheet-metal rim G to it the mouth of the package, a dished expanding-plate within the rim G to bear radially against the same, and means for liattening the dished plate L and holding it flattened.

3. The cover for a package herein specified as comprising a cover-plate E'having a peripheral depressed shoulder F and a generally cylindrical expansible rim G to iit the mouth of the package, a dished expanding-plate L resting on the shoulder F within the rim G to bear radially against the same, and means for vflattening the dished plate L and holding it attened.

4. The cover for a .package herein specified as comprising a cover-plate E having a generally cylindrical eXpansible rim G to t within the month of the package, the rim G being formed with an outwardly-projecting ange I-I to rest upon the shelf C of the package, a dished expanding-plate L within the rim G to bear radiallylagainst the same, and means for iiattening the dished plate L and holding it iiattened.

5. The cover for a package herein specified as comprising a bottom cover-plate E having a generally cylindrical expansible rim G to t; within the mouth of the package, a top plate J fixed to the upper edge of the rim G, a dished expanding-plate L between the plates E and G, and within the rim G, to bear rar dially against the rim G, and means for fiattening the dished plate L and holding it fiattened.

b. The 'cover for a package herein specified as comprising a bottom cover-plate E, and top plate J, having their edges joined by an expansible rim G to it within the mouth of the package, and the `top plate having .a threaded boss N, a dished expanding-plate L between the plates E and J and within the rim G to bear radially against the saine, and a screw M working in the boss N against the center of the dished plate L to iiatten the same and hold it flattened.

7. The cover for a package herein specited as comprising a bottom cover-plate Eand top plate J joined by an expansible rim G to fit the month of the package, the top plate J having a threaded boss N, a dished expanding-plate L between the plates E and J and within the rim G to bear radially against the same, a screw M working in the threaded boss N against the dished plate L to flatten the same, and having a head P, and a bail O hinged to the screw-head P, for turning the screw M and expanding the rim G, and for withdrawing the cover, and adapted to be folded down upon the cover.

In testimony whereof I have hereunto set my hand the 11th day of March, 1896.

GURDON PENDLETON, JR.

In presence of- WILLIAM R. BAIRD, ADOLPH F. Hosen.
