To eel-Z who-m it may concern.

Be it known that I, CHmsroPnER W. LEVALIA-LY, a Acitizen 'of the United States, residing at ilwaukee, in the county of Mil'- waukee and State of Wisconsin, have invented certain new and usefal Improvements in Blacking-Boxes, of which the following is a specification. i Y

Many substances, such as paste shoe polish, have to be'kept in practically a liermetically closed package or box, and thesey are generally made of metal with a closefitting cover or cap. Great difticulty has been experienced in removing the covers because of the fact that they fit so tightly. Resort is usually had to the use of tools for forcing oil' the cover by means of blows or a'prying action, with the usual result that the cover or the box, or both, are so dis torted as t\A make it practically impossible to ti htly Ypply the cover, if, indeed, it is possi le to out it in place upon the box at all, the resenlt being that the lsubstance contained within the package or box is subjectto-the atmospheric influences with resulting deterioration.

My invention has for its object to produce a simple but elicientmeans for easily removing a tightly-fitting cover, and for accomplishing this without distorting either the cover or the box, so that the former may be applied again and again. f

In the accompanying drawings-Figure l is a perspective view of a .blackingbox pro vided with my invention; Fig. 2 is an inside face view of the cover removed from the box; Fig. 3 is a view of a cover illustrating a slightly different embodiment of my invention from that shown in Fig. 2.

In the drawings A-represents the box and B the cover, these parts being of any usual or preferred construction. As shown, they are preferably formed of metal, and the cover is arranged to fit closely the open end of the box. To the inside of the cover is secured a wire 2 preferably by means of solder, as indicated at 3. The wire may be fastened in the angle formed by the'meeting of the flange and top plate of the cover, as indicated in Fig. 2, or it may be secured nearer the middle of the top plate as represented in Fig. 3. The end of the wire is formed into a loop 4 to facilitate its manipulation. The len th of the wire is such that there is a consi erable ortion between the loop 4 and the place o attachment 3, this box.

portion of the wire being bent or coiled within the cover. W'hen the cover' is applied to the box the looped end of the wire is yallowed to project out between the cover' and the bex, as represented in Fig. l. If, when thus arranged, one pulls upon the loop of the wire the cover will be easily lifted tents; and this is done without distorting to any. practical extent either the cover or the When 1t 1s desired t o again close the latented J lily 2, 1'9-12. l

from olf the box, thereby exposing its Ycon- I box the cover is put in place, leaving the looped end of the wire exposed. When this is done the cover may be forced down upon the box tightly to form a practically airtight closure which is not practicable with boxes now commonly in use because of the difiiculty that is experienced in removing the cover when pressed onto the box tightly.

l am aware that it has been proposed to employ a wire secured to the edge of the box and lying between it and the cover with one end exposed for the purpose of removing the cover, but this arrangement, while perhaps a successful expedient for removing the cover of the box in the rst instance, is not adapted to be used again and again, as is my device.

By attaching the end of the wire to the cover the main portion of the wire between the attached end and the exposed loop lies beyond the edge of the box proper, and only a short part is disposed between the flange' of the cover and the body or rim of the box. When draft is applied to the end of the wire the latter is drawn out from within the cover and moves around the box, or 'rather along the joint between the box and cover, thus gradually and easily lifting the cover from its seat.

I have referred to the means for lifting the box cover as being a wire, and such probably will be found to be the most prac-V tical material, but I wish it understood that any flexible article having the characteristic of a piece of wire are intended by me to be included within the term wire, which is hereinafter used in a broad or generic sense.

W'hat I claim is:

l. The combination with a box having an open end and a cover for closing it, of a. flexible wire secured at one end to the inside of the cover at a pontlsuici'ently far from the edge thereof to be above the edge of the box when the cover is applied, and having its f between the cover and the box so it may be grasped, and being of a length suflicient to allow a considerable portion between its ends to lie free within the cover and between the joint thereof with the box and the attached end when the cover is applied, whereby the free portion of the Wire may be drawn out and at the same time carried around the box, thus loosening and removing the cover, and permitting the cover to be applied, and removed by the use of the wire, again and again.

2. The combination with a box and a cover therefor having a flat top plate and a the cover at a point Ain close proximity to the plane of the lower face of the top plate,

the wire being of a length sliliicient to allow a considerable free portion between its ends to be within the cover and above the edge of the box when the cover is applied, the free end of the wire being carried out through the joint between the flange of the cover and the upper end of the box and left exposed to be grasped, substantially as and for the purposes setforth.
