' 16 omies of our invention will definitely appear from the description to follow. tion is defined in the claims.
A structure which embodies the features of our invention is clearly illustrated in the accompanying drawing, in which:
Fig. 1 is a fragmentary longitudinal section of a roll of paperembodying our invention or equipped with our core plugs on The invena line corresponding to line l1' of Fig.
- 2, one of the core plugs being shown in full lines.
Fig. 2'is an inner end elevation of our improved core plug.
In the accompanying drawing 1 represents a tubular core and 2 the roll of paper wound thereon. Our improved core plug comprises a cylindrical rim portion 3 of considerable width having an inwardly tapered portion 4: at its inner end and an outtur'ned flange 5 at its outer end. The cylindrical portion'oi the core has longitudinal ribs 6 struck out therefrom. These ribs, however, terminate in spaced relation tojthe-inner edge of the cylindrical portion as clearly shown in Fig. 1.
These rib portions serve a double time tion; that 01" embedding more or less in the core and preventing rotative movement of the core plug therein, and also making it possible to use thecore plugs in cores varying considerably in diameter, that is, the. ribs embed themselves more or less depend-- ing on the internal diameter of the core and eiiectively hold the plug against rotative movementv even where the cylindrical portion oi the core'plug is not a close flt within the core; 7
The core is provided with a conical or outwardly flaring web portion 7 joined to the inner end of the portion 4 by a flat web -means for lifting or prying prising a cylindrical core-engaging rim -terminating inan outwardly projecting flange and having a central spindle opening proportion 8. The web has a central opening 9 provided with a flange 10 which constitutes 'a'spindle hub lying within the cylindrical j rim portion. The core is formed of a single piece of sheet metal and by thus shaping the web and supporting the hubportion, the core'is not likely to be distorted in slipping upon a spindle or by the use of a spindle or rod engaged within a ,core plug as a I the roll about. Our improved core plugsare' economical to produce, very strong in proportion to the .weight of material used, and, as stated,
adaptable to cores of considerable variation in diameter. 1
Having thus described our invention what we claim as new and desire .to secure by Letters Patent is:
1. A core plug for paper rolls formed as an integral sheet metal stamping and comprising a cylindrical core-engaging rim terminating in an outwardly projecting flange at its outer end and an inwardly tapered portion at its inner end and having a plurality of longitudinal coreengaging ribs struck outwardly therefrom, and an inwardly flaring web joined to the tapered portion of the rim by a relatively fiat narrow portion and having a central spindle opening provided with a flange-like hublying within the said cylindrical portion.
2. A core plug for paper rolls formed as an integral" sheet metal stamping and comat its outer end and an inwardly tapered portion atits inner end, and aninwardly flaring web joined to the tapered portion of the rim by a relatively flat narrow portion vided with aflange-like hub lying within the said cylindrical portion. 5
8. A core plug for paper rolls formed as an integral sheet metal stampingand com prising a cylindrical core-engaging rim terminating in anoutwardly projecting flange atits outer end andhaving a plurality of longitudinal core engaging tapered ribs struck outwardly therefrom, and; a web joined to the inner end of the" and hav- 100 ing a central spindle opening provided with a flange-like hub lying Within the said cylindrical portion.
