To all fui/wm t may concern: A

Beit 1snown that I, FREDERICK Drinnen, a citizen of the United States, and a residentof the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Box Openers, of which the following is a specification.

My invention relates to improvementsin box openers especially adapted for use on blaclring boxes, and has for its object the provision of an improved device of this character which is of simple construction and ei'iicient in use. 1

@ther objects will appear hereinafter. The invention consists in the combinations and arrangements of parts hereinafter de- The invention willbe best understood by the accompanying drawings forming a part of this specification, and inwhich,

. Fig. 1, is aside view ofra boxv equipped with an opener embodying the invention, l j Fig. 2, a top planview of the same,

Fig. 3, a partial side view of the box show-k body 5, removable lid 6, and stop bead 7,V

the vsame constituting` the ordinary forin of box for containing blaclring or the like. A supporting lip'8 is formed at or secured to one side of the lid 6 adjacent the bead 7 and a cam lever 9 is pivot-ally mounted on the under side of the lip 8 by means of a rivet 10 forming a pivot axis extending substantially parallel to the adjacent side of the boX. rlhe cam lever 9 is in channel form, as shown, one portion of said channel being notched or cut away and formed into a cam surface ll adapted to rub against the stop bead 7 of the box when said lever is turned.

The arrangement is such that when the lever 9 is thrown outwardly from the posi.- tion indicated in Fig. 2, to the position indicated in Fig.v 4:, the cam surface l1, rubbing against the stop bead 7 forces the lid 6 upwardly to permit of ready removal thereof. By this arrangement, the lever 9 is held in accurate and constant contact with the bead 7 during operation, and there is no way in which said lever can slip or spring specification of Leitersratent.

over said bead without forcing they lid ups.V

wardly. The action attained is Vpositive and effective for the purpose, and powerful leverage is exerted by the cam action to effect the removal of the lid.

While I have illustrated and described the' preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departl ing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the ap ended claims.

aving described my invention, what 'I claim as new and desire to secure byrLetters Patent is Y 1.,In combination with a receptacle having a lid; a bearing member mounted adj a` cent said'lid; a horizontally swinging lever mounted onsaid lid and an inclined surface on said vlever adapted to ride onV said bearingl *i i member to force the lidv from said receptacle when the lever is operated. Y

2. In combination with-a receptacle having a lid; a bearing member mounted adjacent said lid; a horizontally swinging lever` on said lid; and a cam surface on'said lever soV j having a gentle initially engaging steeply l' increasing curvature adapted to ride on said bearing memberand force the lid from said receptacle when the lever is operated.

3. In combination Vwith a receptacle have.

ing a bead and a lidengagingsaid beadia lever mounted on said lid and swingingin'a horizontal plane; and a cam surface on said lever having a gentle initially engaging steeply increasing curvature adapted to ride on said bead and force the lid from said receptacle when the lever is operated.

et. In combination with Ia receptaclehaving a bead and a lidengaging saidbead, an

opener comprising a lip attached to said lid l and projecting laterally therefrom; a lever` i pivoted on said lip and adapted to swing in a horizontal plane; and a cam surface on said lever adapted to ride on said bead to force the lid from the receptacle when the lever is operated, substantially fas described.

l5. In combination with a receptacle hav-r ing a bead and a lid engaging said bead, an opener 'comprising a lip attached to said lid and projecting horizontally therefrom; a

lever pvoted on said lip to Swingin a horizontal plane and when 1n lnoperatlve pos1-V tion engaging the side of said receptacle;

'and a cam surface on said. lever adapted to ride on Said bead and force the lid iromfsaid receptacle when the lever is swung outwardly, substantially as described.
