JAMES GILBERDS AND MILO HARRIS, OE JAMESTO WN, NEW YORK IMPROVEMENT IN BUT ER-suc ers.

Specification forming part of Letters Patent No. 142,456, dated September .2, 1873 application flied July 25, 1873.

To all whom it may concern:

Be it .known that we, JAMES GILBERDS and MILO HARRIS, of Jamestown, in the county of Chautauqua and State of New York, have invented certain Improvement in that class of Packages used to hold Butter, Lard, Fruit, or other articles of such nature as to require a strong close head or cover for safe transportation and protection from the atmosphere.

Our invention consists in securing the cover to such packages by means of a hoop having flanged edges, or curvedin cross-section, in such a manner that the cover or head is held securely, the package strengthened, and the joint made tight by the same, and is also readily opened when desired for inspection.

And to enable others skilled in the art to make and use our invention, we proceed to describe its construction, reference being bad to the accompanying drawings and the letters of reference thereon, in which- Figure l is an elevation of a package with our invention, and Fig. 2 is a sectional view of the same, in which A is the hoop; B, the cover; (1, the package; D, the rubber packing; E E, flanges on each end of hoop; I screw for connecting the two ends of hoop and drawing them together; G, lever for turning the same. The package 0 is made in the general form of such packages from staves with bottom grooved in and held together by means of hoops; or it may be con structed of other materials in convenient forms. The cover B is made of sufficient thickness to allow a flange to extend over the top of the package, said flange being about one-half as thick as the hoop A is wide, while the under side of said cover projects into the package, fitting closely, as shown at H, Figs. 2 and 3. The cover B isalso rounded on its upper corner in form of a quarter circle, and a corresponding quarter circle is out on the outer edge of package, the two forming a rib of semicircle or semi-elliptical cross-section, with the cover joint along its medial line. The hoop A is made, and swaged in form, to fit this said rib, except that its edges are a little shorter, and it has flanges E E at each end,

into which the screw F is turned by the lever Gr, drawing the ends together, thereby securing the cover to the package, and making a cheaper, closer, and more durable package than others.

We sometimes make the hoop for this purpose with a flange on each edge, the lower flange fitting a groove in the side of the package, and the upper one extending over the edge of cover, as shown, and which may be drawn together, as before described, but prefer the semicircle or semi-elliptical form, as it draws the cover more firmly to the package. \Ve also sometimes use a thin rubber packing between the .hoop A and edge of cover and package to more thoroughly guard against the atmosphere in case of shrinkage of package, or when the hoop may not be drawn sufficientlytight, thereby making an air-tight package. On jars and the like, in place of the semicircle,

we prefer a raised bead or flange around edge of cover and jar, the cover being held as before. We also forsome purposes prefer the flanged hoop to be made ofrubber and stretched over these beads, so as to hold the cover without the aid of the metal hoop.

The hoop A with curved cross-section, when tightened up by its clamping device, operates in both vertical and lateral directions, and

not only draws the cover downward upon the upper end of the package, as heretofore, but it also contracts said upper end and forces it inward against the shoulder or portion of the cover B, which projects downward into the package, and thereby the inner upper an gle of the package is forced into the angle II of the rabbet of the cover, and the cover may be made tight without the use of elastic packin g. The walls of the package 0 are sustained against lateral pressure by the rabbeted shoulder of cover B, and the clamping-hoop A so strengthens said upper end that it will remain undamaged even if the ordinary upper hoop be broken or displaced.

By these means apackage is produced which, while it will preserve its contents securely pro tected from atmospheric action and the risks of storage or transportation, may readily be opened for inspection of the contents, and as readily closed again. 7

We are aware that a fruit-jar has been provided with a cover held in place by a clamping device, which pressed it downward upon 2 Manse the upper edge of said jar; and, also, that such covers have been made with shouldered portions projecting downward within said jar; and, also, that elastic washers have been placed beneath said covers to pack the joint; but we'are not aware that a package has ever been made having a cover with a shouldered portion of the same fitted to, and projecting within, the open end of said package, and a clamping-hoop, having a curved cross-section capable of securing said cover in place, and at the same time clamping said package against the shoulder of the cover, as and to the effect above set forth; nor are we aware that an elastic band has ever been placed beneath a joint, as described.
