I, HENRY SCOTT, of 10, William Street, Dundee, in the County of, Forfar,
Scotland, Grocer, do hereby declare the nature of this invention to be as follows:-
This invention relates to openers for sealed meat tins and the like, the object
being to facilitate the movement of the opener in its progress round the tin.
In carrying out my invention I employ a handle in which is fixed a knife whose
cutting edge is so arranged that it acts on the metal from the inside of the tin.
Above the knife and at a small distance from its cutting edge is a roller. Such
roller may be of cylindrical shape; or its diameter may be larger at its extremities
than at its centre, or conversely, or it may have. flanged edges and its surface may
be roughened. The metal which is being cut passes between the roller and the
knife. The function of the roller is to cause the knife to move along more freely
and to assist in keeping it in the most suitable position for cutting.

Improvements in Openers for Sealed Meat Tins and the like.
I, HENRY SCOTT, of 10, William Street, Dundee, in the County of Forfar,
Scotland, Grocer, 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 openers for sealed meat tins and the like, the object
being to facilitate the movement of the opener in its progress round the tin.
And in order that my said invention and the manner of performing or carrying
the same into effect or practice may be properly understood, I have hereunto
appended an explanatory sheet of drawings in which the same reference numerals
are used to indicate corresponding parts in all the figures where shown, that is to
say:-
Figure 1, is a side elevation of the opener.
Figure 2, is a plan, and
Figure 3, is an end elevation looking in the direction of the arrow A, (Figure 1).
In carrying out my invention I employ a handle 4, in which is fixed a knife 5,
whose cutting edge is so arranged that it acts on the metal from the inside of the

page_text: tin. Above the knife and at a small distance from its cutting edge is a roller 6.
Such roller may be of cylindrical shape; or its diameter may be larger at its
extremities than at its centre-as is shown in, the drawings--or conversely, or it
may have flanged edges and its surface may be roughened. The metal which is
being cut passes between the roller and the knife. The function of the roller is
to cause the knife to move along more freely and to assist in keeping it in the most
suitable position for cutting. The knife is preferably removable and fits into a
recess in the handle it being held therein by means of a screw 7. 8, is a pointed
piece of tempered steel whose purpose is to make the initial opening in the can.
The roller is preferably of hardened steel or chilled cast iron.
In using the opener the point of the knife is inserted in the opening made by
the piece 8, and then run round the tin, the roller at that time bearing against such
tin and so assisting in keeping it from going too deep and at the same time
permitting it to move along more readily than the ordinary type of opener because
rolling is substituted for sliding friction.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:
-
(1) In openers for sealed meat tins the use of a roller as described.
(2) In openers for sealed meat tins the combination of a roller with a knife, as
described and illustrated.
(3) In openers for scaled meat tins the combination of a roller with a knife and
handle, substantially as described and illustrated.
(4) In openers for sealed meat tins, the combination of a roller with a knife,
handle and initial opener, substantially as described and illustrated.
