. Improvements in Sardine Tin Openers and the like.
I, GEORGE PARROTT, of Bicester, in the County of Oxford, Coach Builder, do
'hereby declare the nature of this invention to be as follows:-
A.tin can opener according to this invention has a slightly laterally turned blade,
the cutting portion being on the top curved round towards the point which is at the
bottom. On the underside of the blade near junction of stem part is a divided
claw,. one part of which is a guide for the cutting edge, and the other part. is made
with a sharp, face or edge to grip or bite the edge of the tin to facilitate the cutting.
The straight part of the blade is used for cutting straight, and the laterally curved
part for cutting round.

Improvements in Sardine Tin Openers and the like.
I GEORGE PARROTT of Bicester in the County of Oxford Coach Builder 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 a tin can or box opener, having a cutting blade which is
laterally curved towards the point, the cutting portion being formed upon the upper
edge which latter curves downwards terminating in a point located at the extreme
end of the lower edge of the blade. I provide the blade with a part projecting
laterally opposite to the direction of the curve, such part serving to form a fulcrum
and to grip the edge of the tin can or box to facilitate the feed of the knife while
there is also a part projecting downwards from and in a plane with the cutting blade
and which serves as a guide for the cutting edge of the blade.
My invention will be readily understood by the following description which refers
to the accompanying drawings, whereon Fig. 1 is a side elevation of a tool or instru-
ment constructed according to my invention. Fig. 2 is a plan view of same, Fig. 3
is a transverse section on the line X. Y. of Fig. 1, and Fig. 4 is a perspective view
showing a position of the tool when in use.
A, is the cutting blade which in the example shown is a continuation of a stem
part A, and B is the cutting edge curved downwards as shown at Fig. 1, the blade
itself being bent laterally as at Fig. 2, formed with or attached to the blade A is the
laterally projecting fulcrum C, formed with a (preferably downwardly inclined)
knife edge C, Fig. 3, while below and projecting downwards from the blade is the
guide D.
The stem A, of the blade is fitted into a suitable handle E, as at Figs. 1 and 2.

page_text: As will be understood from the perspective view Fig. 4 when cutting, the handle E
is pressed downwards, the part. C acting as a fulcrum on the box F, the knife
edge C, gripping same and acting as an aid in traversing the blade while the part D
acts to guide and maintain the direction of the said blade A. The laterally curved
extremity of the blade A is brought into action when cutting round the corners of the
box or when making a curved, or circular incision which by this construction of tin
opener is effected with greater facility than heretofore and in a more regular and
even manner.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare- that what I
claim is :-
1. In sardine tin openers and the like, the combination with the blade A, having an
upper cutting-edge, curved laterally towards the extremity thereof, of a fulcrum
part C projecting laterally from the blade in an opposite. direction to the curvature
thereof and formed with a sharp acting edge to grip the tin and aid in traversing
the blade substantially as described:
2. In sardine tin openers and the like, the combination of a blade A,. curved
latérally and having an upper cutting edge, a laterally projecting fulcrum part/C,
with a sharp acting edge and a downward projection in the plane of the stem of
the blade, to act as a guide to the cutting edge substantially as described.
3. The general construction and arrangement composing the improved tool or
instrument for opening tin cans or boxes substantially as and for the purposes
described and illustrated with reference to the accompanying drawings.
