invention to be as follows
The object of my invention is to provide an instrument for opening tin and other
cans or boxes in which preserved meats, fruits and other produce are supplied for
sale and use.
For this purpose I employ a slotted blade or bar carrying an adjustable bracket
or stud with a sharp edged roller and having a hent point at one end which pierces
the lid or cover of the can or box and acts as a pivot and fulcrum for the sharp edged
roller to be worked round and pressed against the lid or cover so as to cut same
through in a circle.
The bracket or stud is provided with a screw and nut by which it may be
fastened in the slot at any desired distance from the pivot according to the diameter
or size of the lid or cover to be cut.

Improvements in Instruments for Opening Preserved Meat Cans
and other Boxes of a similar kind.
I, JAMES RUSSELL BRADY of 5 Holborn Terrace in the City late Borough of
Belfast and County of Antrim in Ireland Master Mariner 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 :-
The object of my invention is to provide an instrument for opening tins and other
cans or boxes in which preserved meats fruits and other produce are supplied for sale
and use.
For this purpose I employ a radial slotted blade or bar carrying an adjustable
bracket or stud with a sharp edged roller and having a bent and pointed end which
pierces the lid or cover of the can or box and acts as a pivot or fulcrum for the sharp
edged roller to be worked round and pressed against the lid or cover so as to cut the
same through in a circle or circularly.
The bracket or stud is fitted into and passes along the slot in the radial blade or
bar and is provided with a screw and nut or spring by which it may be fastened or
held in the slot at any desired distance from the pivot or fulcrum according to the
diameter or size of the lid or cover to be cut. I prefer to use a spring in most
instances as a simpler and less expensive means of preventing the bracket or stud
from shifting in the slot and when I so fit the instrument with a spring I notch or
roughen the under side of the radial slotted. blade or bar and I form a flange on the
bracket or stud and notch or roughen the upper side thereof to correspond with the
under side of the blade or bar and to give it a better bite or hold thereon.
And I form in the radial blade or bar a circular, oval or other enlarged perforation
at one end of the slot sufficient to admit the head or top of the bracket or stud so
that the bracket or stud may be placed in or removed from the slot at pleasure.
And in order that my said invention may be more fully understood I shall now
proceed to refer to the sheet of drawings hereunto annexed, the same letters being

page_text: used throughout all the figures to indicate the same or corresponding parts of the
instrument.
Fig. I is a longitudinal elevation of the radial slotted blade or bar notched under-
neath and with a bent and pointed end thereon and a sharp edged roller carried by a
flanged bracket or stud correspondingly notched on the top and passing through the
slot of the radial blade or bar, with a spring to hold it in position.
Fig. II is a plan of the parts shewn on Fig. I and
Fig. III is a transverse section of the radial blade or bar with the flanged bracket
or stud and roller in the slot and the spring holding them in position in the notches
of the blade or bar.
a is a radial slotted blade or bar, notched underneath to prevent the flanged and
notched bracket or stud, b, from shifting along the slot when being used and having
the bent and pointed end, c, by which it is fixed into the lid or cover of the can or
box to be opened; d is the sharp edged roller carried by the bracket or stud, b, to
be pressed against the lid or cover of the can or box, which is cut through by it
circularly; e is a spring to hold the two notched faces together and prevent the
bracket or stud from shifting in the slot and is a perforation in the radial blade or
bar through which the bracket or stud and roller may be introduced into or removed
from the slot at pleasure.
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. A radial blade or har arranged with a slot and a bent and pointed end employed
substantially in the manner and for the purposes hereinbefore described and shewn on
the drawings hereunto annexed.
2. The use, in instruments for opening meat tins or other cans or boxes, of a sharp
edged roller constructed, carried and employed substantially in the manner and for
the purposes herein before described and shewn on the drawings hereunto annexed.
3. The use, in instruments for opening meat tins or other cans or boxes, of a pivot
or fulcrum constructed and employed substantially in the manner and for the purposes
herein before described and shewn on the drawings hereunto annexed and
4. The combinatiou and arrangement of parts constituting my improved pre-
served meat and fruit tin opener constructed and employed substantially in the
manner and for the purposes hereinbefore described and illustrated by the drawings
hereunto annexed.
