To all whom 'it may concern Be it known that we, EDWARD P. PULLEN, a citizen of the United States, and AnoLPi-I F. BnoEoKEL, a subject ofthe Emperor of Germany, and both 'now residingrespec tively, at Hackensack, in the county of Bergen and State of New Jersey, and at West Hoboken, in the county of Hudson and said'State of New Jersey, have jointly invented certain new and vuseful Improvements in Sitting-Top Cans, of which the following is a .specication Our invention has relation to a sifting top can for ly'e and other preparations; and in such connection it 'relatesto the particular arrangement of the sifting top or end in its connect-ion with thev can-body, for the above defined purposes.
Our inventionl for a sifting top can em-l braces first, an outer metal cap having perforations for sifting therethrough the contents of the can, and which is peculiarlyy seamed in connection with a flange of the can-body; second, an lnner metal disk having an opening as large in diameter as or larger in diameter than the diameter of a circle circumscribing the perforations in the outer metal cap and having a periphery to rest upon the liange of the can-body, but small enough so that its outer edge does not extend beyond the outer edge of the flange of the can-body, in order that duringthe operation of seaming 4the outer cap onto the can-body the outer edge of the lnner' disk will be rolled over only-enough so that after being turned down parallel with the body of- `the can itwill not again turn up parallel with the can-body; and third, between the 'top' perforated cap and inner disk is placed a layer of paper saturated with parain, rosin, or a mixture of parailinand rosin or `other materials impervious tothe action of lye, caustic soda, etc., and this .layer has a diameter approximately equal to the inside I diameter of the can; the paper layer being unattached to either the cap or theY disk of the can-body, and the said three elements constituting. the sifting top of the can secured by the usual seaming or crimping operation of the cap onto the can-body, to thereby secure the siti'ngtop in such manner as that the layer of prepared paper is held firmly in position, thus producing an air-tight lye or caustic preparation proof container for shipment, and a can which requires for use of -contents merely the perforatlon of the interposed paper layer to an extent of any or all off vthe perforations in the said cap, for removal of such contents.b
The nature and sco e of our present in vention will be more illy understood from the following description taken in connection with the accompanying drawings forminpart hereof, in whichlgure 1,. is a pers ective view of. the Aseveral parts of the si ting Itop can, detached from the can-body, which whed assembled embrace the Amain features of our present in-A vention. Fig. 2, is atop or plan view ofthe sifting top shown in operative relation with the can-body, for shipment and Fig. 3 is a vertical broken sectionalview on the line w-w, vof Fig. 2, showing how the outer edge lofthe perforated cap is formed in conjuncperforations b1, formed therein, in prefer?V ably rows of three openings at right angles to each other. The. periphery of the cap b, is provided with a' crimping gutter-like ange b2, having an outer down-turned lip b3, arranged so 'that the flange of the said cap fits onto the said flange a1, of the canbody a, and by an ordinary` crimping or seaming operation the two 'anges are readily secured permanently to .\each other.
c, is the inner metal centrally perforated disk, the perforation c1, beingin` diameter as large or larger than a circle circumscribing the series of small perforations of the cap a, This'inner disk c, has a periphery arranged to rest on the flange a1, of the can-body a, but small enough so that its outer edge cdoes not extend beyond the outer edge of the flange a1, of the said canbody, in order that during the seaming of the cap b, to the can-body a, the' eriphery of the inner disk is rolled over o y enough that after being turned down parallel tn the can-body, it does not turn up parallel with the can-body, as will be apparent from the sectional view Fig. 3, of the drawings.
d, is a layer of paper saturated with parain, rosin, or a mixture of parafiin and rosin or other materials impervious to the action of lye, caustic soda or the like, and which paper circular slip or layer is of a diameter approximately equal to the inside diameter of the can. The said paper slip or layer d, is placed between the' cap b, and disk c, and the said elements then assemf bled are ap lied to one. end of the can-body a, and wit the inner disk resting on the flange al, of the canfbody a, and with the flange of the perforated cap b, resting on the crimped overlapping Bange a1, of the can-body, to securely attach the cap b, to the can-body a, by crimping of the respective ianges of the c ap and can-body to each other, resulting in so attaching the cap to the can that the said circular slip o'r layer of paper d, will be held between saidcap b, and disk c, to provide an air-tight lye or caustic soda proof 'capped can, for shipping; and in order that by perforating the paper about perforations of said cap suitable openings will be provided for the removal of the contents of the can, for use. Having thus described the nature and objects of our invention, what we'claim as new and desire to secure by Letters Patent 1s:-
The combination, in a sifting top can, of a body formed into tubular form and provided with an outwardl extending end flange al, a disk c, provlded with an endisk provided with an outwardly extending flange c, arranged to rest upon the fiange al, but not to extend beyond the same, an unianged disk d, of paper saturated with para-Hin or rosin or a mixture of parain and rosin to render the same free from the action of lye, caustic soda or the like, fitted to the disk 0, and snugly contouring therewith below the flange thereof and a perforated cap provided with an outwardly extending inverted gutter-like flange b2, provided with a down-turned lip b3, fitting under the flange a1, and against said body ka, to permanently secure the several parts together, of said sifting top can.
In witness whereof,- we have hereunto set our signatures in the presence of the two subscribing witnesses.
