Improvements in Tin Openers.
We, HORATIO Saqui of 29 and 30 Liverpool Street in the City of London,
Jeweller, HENRY NORWOOD BRENT Traveller of South Weald in the County of
Essex, and FRANCIS MARSH Engineer of 38 Kingswood Road, Penge, County of
Surrey, 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 relates to implements for opening tins such as are commonly
employed for meat, fruit, vegetables etc. This improved implement has the
advantages over other tin openers that it is suitable for either round or square
tins, the round tin being opened by cutting with the implement a circular disc out
of the end and the square or similar tin by cutting out the piece of the required
shape either from the top or cutting round the sides so as to cut the top entirely
off; square tins may be opened by cutting out a circular piece from the end,
but as this would leave closed corners, we prefer to provide means for getting rid
of these.
The invention will be best understood by reference to the accompanying drawings
in which,
Figure 1 is a perspective view of the complete instrument for cutting circular
holes,
Figure 2 being a side or face view and
Figure 3 a side view partly in section of the implement with the addition for
cutting squares as well as rounds.
Like letters represent like parts throughout the drawings.
A is a bar or equivalent preferably provided with a handle B and slotted at C to
receive a movable point D which can be adjusted to any position in the slot and
may be fixed by screwing up the wing nut E. B₁ is a collar or enlargement upon
the point D to prevent it slipping through the slot C and E is a washer against
which the nut E which screws on to the screwed portion D2 of the point D bears.
The portion D³ of the point D is shaped so as to fit in the slot C and thus prevent
the point from turning while the nut is being turned.
Fis a fixed knife or cutter and A' is the closed end of the bar A which may be
used if desired for applying pressure to that end of the implement either for
holding it upon the tin or forcing the point D through the tin.
In use the implement as above described and shown in Figure 1 of the accom-
panying drawings is held by the handle B and the tin struck with the point D
which thus perforates or marks it and secures a hold while the implement is moved
round the point D as a centre the cutter F thus cutting out a circular disc from the
end of the tin. By making the point D adjustable the distance between D and F
can be varied so that the implement may be used for tins of different sizes.
The arrangement illustrated in Figures 2 and 3 of the accompanying drawings
is similar to that above described but the end A¹ of the bar A is enlarged so as to
provide a bearing surface G with a flange or edge G and a knife H secured
thereto, the construction of this part of the implement being similar to that of a
common and well known form of tin opener. This part of the implement is used
in the well known mauner and is suitable for opening square or other tins having
straight sides and corners; it may also be used for cutting out the ends of round
tins but does not do this nearly so neatly as the arrangement described in relation
to Figure 1.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination in a tin opener of an adjustable point or centre and a fixed
knife or cutter.
2. A tin opener having a knife or cutter such as F fixed at or about the centre
of its length and an adjustable point such as D substantially as and for the
purpose described and illustrated in Figure 1 of the accompanying drawings.
3. The combination in a tin opener of means such as described for opening
either round or cornered tins.
4. In a tin opener the combination in the same implement of an adjustable
point such as D a fixed cutter such as F and an ordinary tin opening device such
as G H.
5. The combination and arrangement of parts constituting the combined tin
opener substantially as described and illustrated in Figures 2 and 3 of the
accompanying drawings.
