To all whom it may concern:

Be it known that I, FREDERICK VVEs'rnR- BECK, a citizen of the United States of America, and aresident of the city of St.

in the State'of Missournhave invented certain new and useful Improve ments in Sheet-Metal Boxes, of which the following is'a full, clear, and exact description, reference being had to the accompany ing drawings, forming a part of this specification. i v;.

invention relatesito sheet metal boxes such as are commonly used to hold shoe blacking. Boxes of this kind include a cylindrical body and a slip cover having a flange that frictionally engages the wall of the body. The wallof the box body is provided with an outwardly jutting which serves to limit the downward movement of the cover flange on the body wall. It is particularly desirable in making such boxes that the wall of the box body and the flange of the cover be made as nearly as when the cover flange is fitted to the box body wall, a very close joint will be provided between these members, so that air may be excluded from entrance to theinteriorof thebox. Boxes made as closely as possible in accordance with the foregoing have their covers so closely fitted to the box body walls as to render it extremely difiicult to remove the covers without injury to the box, the difficulty of removal being pronounced owing to the presence of the stop beads on the box bodies, which, due to their being located immediately beneath the lower edges of the cover flanges, act to prevent the ready introduction and movement of a sharp implement between the cover flange and box body wall to loosen the former from the latter, and permit the removal of the cover.

From the foregoing it will be perceived that it is highly necessary to locate any means serviceable for the removal of its cover beneath the contacting portions of the box body wall and the flange of the cover, and also that it is highly important to have such contacting surfaces in parallel lines, as otherwise the binding engagement between the cover flange and the box wall is imperfect.

The box made in accordance with my present invention is constructed with the object' in view of providing all the desirbead able features necessary to produce a box as nearly as possible air tight, where such box. includes a slip cover, the flange of which .is secured to the box body wall by frictional engagement only, and provide in such box a construction that permits the ready application of a knifeblade, or other sharp implement between the cover flange and thebox body wallfor the purpose of loosening the former from the latter, in

order that itmay beeasily separated therefrom. i

In the accompanying drawings :-A designates the body of my box and B its cover. The box body comprises a bottom 1, and a wall 2,the portion 2 of which hasan outer face extending strictly. in avertical plane. Between thelower portion of the box body wall and the upper portion 2 is an outrron.

wardly jutting head 3 that extends circum ferentially of thevbox and is intended to serve as a stop for the flange of the cover B whensuch flange is fitted to the box body wall portion 9/. The bead'S does not completely encircle the'box'body, but is discontinued at a given point to provide a gap 4:

between endsof the head, which latter are inclined inwardly at their terminals where they merge into the box body wall at oppo" site sides of the gap 4.

The body wall of my the location of'the gap a betweenthe ends of the beads 3 with an indentation 5, the upper end of which is located at the base of the cover flange receiving portion 2 of the box body wall. This indentation is preferably box is provided at inclined upwardly and also downwardly from a point about midway of the height of v v the bead 3, and is adapted to receive the blade of a knife, or other sharp implement, which may be utilized to separate the flange of the cover B from the box body wall.

The flange 6 of the cover B is so made as to conform at its inner face as nearly as possible to the outer face of the box body as Would be incurred if the lower edgeof the cover flange were curveduoutwardly to cn--.

form to the upper face ofthestop bead 3 beneath it.

' The flange of the cover B is provided With a downwardly jextending straight tongue 7 i that enters into the gap 45 betweenthe ends of the head 3 when the cover is applied to the box body, andwhich is, therefore, so

located asv to be protected by the bead; and,

furthermore, cause the bead to serve as: a guard that Will prevent injury to. the hands I of a person handling the box to. open it. It

Will be obvious thatinasmuch asithe tongue extends into the gap at; it also occupies a upwardly through the upper end of the. in.-
