An Improved Tin Opener.
Year: 1899

page_text: I, NIELS AULIN, Gentleman, of Buluwayo, Matabeleland, do hereby declare the
nature of this invention to be as follows:-
This invention for an improved tin opener has for its object an improved
construction whereby the operation of opening a tin, can or the like is greatly
facilitated.
According to this invention, the tin opener is in two main portions pivoted
together near one end and provided at their other ends with suitable handles
preferably of the character usually provided for scissors and the like. To the
outer end of one member a small rod is pivoted passing through a slot in the
other member and provided with a suitable cutting knife. The other end of this
rod is preferably enlarged. Upon the other member a small side pin is pivoted
so that it can be turned out at right angles or can be fitted in a groove out of the
way. A saw cut or the like is preferably made in the outer end of this pin. A
spring between the two members serves to return the parts after each operation.
In using the device the knife which is preferably pointed is forced into the
tin, and by working the opener scissors fashion, the upper edge of the knife cuts
through the tin the lower surface of the device providing a resistance. The side
pin acts to guide the opener in use.
The parts may be inade of any suitable material but preferably of iron or
steel. The knife and side pin should be of steel and the knife is preferably of
such shape that on its lower edge there is a pointed cutting surface and on the
upper edge another cutting surface.

An Improved Tin Opener.
I, NIELS AULIN, Gentleman, of Buluwayo, Matabeleland, 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 for an improved tin opener has for its object an improved
construction whereby the operation of opening a tin, can or the like is greatly
facilitated.

page_text: According to this invention, the tin opener is in two main portions pivoted
together near one end and provided at their other ends with suitable handles
preferably of the character usually provided for scissors and the like. To the
outer end of one member a small rod is pivoted passing through a slot in the other
member and provided with a suitable cutting knife. The outer end of this rod
is preferably enlarged. Upon the other member a small side arm is pivoted so
that it can be turned out at right angles or can be fitted in a groove out of the
way. A spring between the two members serves to return the parts after each
operation.
In using the device the knife which is preferably pointed is forced into the
tin, and by working the opener scissors fashion, the upper edge of the knife cuts
through the tin the lower surface of the device providing a resistance by the
bearing upon the top of the tin.
The parts may be made of any suitable material but preferably of iron or
steel. The knife and side pin should be of steel and the knife is preferably of
such shape that on its lower edge there is a pointed cutting surface and on the
upper edge another cutting surface.
In order that this invention may be more clearly understood, reference is had
to the accompanying sheet of drawings in which
Figs. 1 and 2 are side views of my device shown in two positions, Fig. 2 being
partly in section, and
Fig. 3 is an underside view.
The two levers A and A' are pivoted together at a and have at their ends the
rings a by which they are held and operated. The ends of these levers are formed
so as to lie flat against each other when released the spring B opening them at the
handle end and closing the other ends together.
The upper lever or member A carries the pin C which is pivoted to it and passes
through a slot close to its end, also passing through a slot or aperture in the
end of the lower lever, which is enlarged and has its under surface flattened at
an angle to the main part of the opener.
The pin C has at its upper end a head c and terminates at its lower end in a
blade Ď of peculiar form. This blade is preferably of triangular shape having
cutting edges and a sharp point at its lower side and also a sharp cutting edge d
at the upper side, preferably of curved form.
The under surface of the lower lever A is provided with the groove a² to receive
the top of the cutting blade when drawn into its upper position as shown in
Fig. 2 and it is also formed with the lip a³ which bears against the edge of the
tin during the opening process.
To the side of the lever A is pivoted a small arm E which normally lies in a
groove in the side of the lever. The arm can be extended at right angles to the
lever to serve as a stop and it is provided with a spring e to retain it in open or
closed position. The end of this arm is formed with a cut dividing it into two
parts.
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) A tin opener, comprising two levers pivoted together, a pin carried on the
end of one lever and extending through the other, and a cutting blade on the
end of the said pin adapted to enter the tin and to cut it as the levers are operated,
substantially as described and for the purposes specified.
(2) An improved tin opening apparatus, comprising two levers pivoted together,
a spring returning them to open position after each operation, a pin pivoted to
one lever and passing through the other, and a triangular blade on the end of the
pin having cutting edges at the top and bottom, substantially as and for the
purposes specified.

page_text: (3) The improved tin opening device constructed and operating substantially
in the manner described and shown in the accompanying drawings and for the
purposes specified.
Dated this 12th day of March 1900.
