PROVISIONAL SPECIFICATION.
Improvements in Can Openers.
1, HOWARD RENO, a citizen of the United States, residing at Folsom in the County
of Colfax and State of New Mexico, U.S.A. Stockman, do hereby declare the nature
of this invention to be as follows :-
This invention relates to a new and original design for can-opener blades, and it
will be fully understood from the following description.
The blade has a reduced shank at its rear end and from said shank the upper and
lower portions of the rear edge of the blade diverge. The upper portion of the rear
edge merges at its upper end into the upper longitudinal edge, which describes a
convex curve and is beveled and the lower portion of said rear edge merges at its
lower end into the lower longitudinal edge, which describes a compound curve, being
concave at the rear portion of the blade and convex at the forward portion thereof.
The blade is reduced gradually in width and thickness from its rear edge to its
forward end, and the lower longitudinal edge extends to said forward edge. The.
upper longitudinal edge, however, is shorter than the lower longitudinal edge and
merges at its forward end into the straight and flat or non-cutting edge which extends
to the forward end of the blade, the under edge being a cutting edge.

Improvements in Can Openers.
I, HOWARD RENO, residing at 1212 Hennepin Avenue, in the City of Minneapolis,
in the County of Hennepin, and State of Minnesota, United States of America,
late of Folsom, Colfax, New Mexico, U.S.A., Stockman, 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 blades for can openers and the object thereof is to
provide a device of this character which is simple in construction and operation
and with these and other objects in view, the invention consists in the construction
herein more fully described in the specification and illustrated in the accompanying
drawing in which:
The figure of the drawing shows a perspective view of the blade of the can opener.
In the practice of this invention the blade has been constructed with the reduced
shank or end portion B, from which the blade tapers upwardly and forwardly as
shown at C and is then curved outwardly and downwardly and the edges of the
curved portion are beveled or inclined to form a cutting edge D and this curved
portion terminates in a point or prong E, which extends outwardly therefrom, and
the lower surface of the blade is downwardly and outwardly and then inwardly and

page_text: rearwardly curved as shown at .F,to form a shoulder from which the blade extends
backwardly to the shank.
From this construction it will be seen that the prong E, can be readily inserted
into the head of the can to form a puncture therein which can be enlarged by the
cutting edge D..
It will be also observed that the enlargement in the rear of the prong E will
furnish a bearing surface for the device when the same is being operated.
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 blade for can: openers, .consisting of a shank from which: the blade tapers
outwardly to form a segmental cutting edge and terminates in an outwardly directed
prong, substantially as shown and described.
2. A blade for can openers, consisting of a reduced portion or shank from which
the blade tapers upwardly and outwardly forming a segmental cutting edge which
terminates in an outwardly directed prong, the under surface of said blade being in
the form of a compound curve and terminating in the shoulder which' extends back-
wardly to said 'shank, substantially as described.
