Bristol, and HUGO VON RIETZENSTEIN CUNLIFFE-OWEN, of the same address,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide improved means to be used in con-
nection with metal cases, or boxes especially such as are hermetically closed, for
the purpose of severing the tagger plate, or inner top thereof.
In devices as hitherto used, wherein a cutter forins part of, or is permanently
attached to, the outer cover or lid which is placed over the tagger plate, or inner
top, there is liability to the said tagger plate, or inner top, being perforated
accidentally (before it is required to open the box, or case) by reason of the said
cutter not being in proper position when the outer lid, or cover, is put in place.
According to this invention there is provided a separate knife, or outter, prefer-
ably flat, or of such shape that it can be placed between the inner and outer tops
of the box, or oase, without danger of perforating the former. The said knife, or
cutter, is so shaped that it can readily be secured to the outer lid, or cover, so that
the cutting portion projects therefrom in position to cut the tagger plate or inner
top. The means for securing the cutter, or knife, to the outer cover, or lid, may
be of any suitable kind, such for instance as slots in the sides of the upper part
or shank of the cutter, or knife, and a radial slot in the cover, or lid, so that by
passing the shank through the said slot in the cover, or lid, until the slots in the
shank of the knife or cutter, coinoido with the motal at the sides of the slot in the
cover, or lid, and then turning the said knife, or cutter, at right angles to the last
named alot; the knife, or cutter, is firmly secured in place; or the shank of the
knife, or cutter, may take the form of a stem passed through a hole in the outer
cover, or lid, and secured therein by a cotter passed through a slot in the said
shank, or by a screw-nut screwed thereon.

Boxes or Cases.
We, W. D. & H. O. WILLS, LIMITED, of Bedminster, in the City and County of
Bristol, and HUGO VON REITZENSTEIN CUNLIFFE-OWEN, of the same address,
Engineer, do hereby declare the nature of this invention and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement:-
-
This invention has for its object to provide improved means to be used in con-
nection with metal cases, or boxes, (especially such as are hermetically closed), for
the purpose of severing the tagger plate, or inner top thereof.
In devices as hitherto used for this purpose, wherein a cutter forms part of, or
is permanently attached to, the outer cover, or lid, which is placed over the tagger
plate, or inner top, the said tagger plate, or inner top, is liable to be perforated
accidentally (before it is required to open the box, or case,) by reason of the said
outler not being in its proper inactive position when the.outer cover, or lid, is put
in place.
According to this invention there is provided a separate knife, or cutter, prefer-
ably flat, or of such shape that it can be placed between the tagger plate or
inner top and outer cover, or lid, of the box, or case, without danger of perforating
the tagger plate, or inner top. The said knife, or cutter, is so shaped that it can
readily be secured to the outer cover, or lid, when required so that the cutting
portion projects therefrom in position to cut the tagger plate, or inner top. The
means for securing the cutter, or knife, to the outer cover, or lid, may be of any
suitable kind and we have shewn several arrangements in the accompanying
drawing, but we do not limit ourselves thereto.
Figure 1 shows a cutter, or knife A, with slots a, in the sides of the shank thereof.
The lower part a, is the cutter or knife, proper, and the upper part as is a flat
piece to be grasped between the finger and thumb. In the outer cover, or lid, B,
is a radial slot 6 as shewn in Figure 2 in perspective, and in Figure 3 in section.
By passing the part a through the said slot b, in the cover, or lid B, until the
slots a in the shauk of the knife, or cutter, coincide with the metal at the sides
of the slot b, in the cover, or lid B, and then turning the said knife or cutter A
at right angles to the last named slot, as shewn in Figure 3, the knife or outter A
is firmly secured in place for use in cutting the tagger plate, or inner top C, as
shewn in Figure 3. Figure 4 shews a modification in the form of the cutter in
which there is a slot a, only at one side. Figure 5 shews a knife, or cutter, with
a stem in the form of a screw a', to be passed through a hole 6, in the cover, or
lid, B, as shewn in Figure 6, and secured for use by means of a thumb nut a³.
Or the stem a, may be perforated as shown in Figures 7, and 8, and be secured by
a cotter-pin a, passed through the perforation in the said stem. Either of the
knives, or cutters, and the means by which they are secured in place, if separate
means (such as the nut, or cotter-pin,) be used therefor, may be placed in the space
between the tops B, and C, as shown in Figure 9 and, when required for U60, the
cover, or lid, B is removed and the knife, or cutter, fixed in place thereon as
herein before described, and then the cover, or lid, B, is put in place again upon
the box or case, and forced down so that the knife, or cutter, penetrates the tagger
plate, or inner top, C, as shewn in Figure 10, and, on the cover, or lid, B, being
rotated the cutter, or knife, inakes a círcular cut in the said tagger plate, or inner
top, and severs it from the box, or case.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed we declare that what we
claim is:-
1. In connection with metallic boxes, or cases, a separate knife, or cutter,
adapted to be placed between the outer cover, or lid, and the tagger plate, or inner
top, the outer cover, or lid, and the knife or cutter, being provided with means
whereby the cutter can be secured to the outer cover, or lid, for use in severing
the inner top, or tagger plate; substantially as herein before described.
2. The several devices herein before described and illustrated in the accompanying
drawings for the purpose set forth.
