COMPLETE SPECIFICATION.
Finger Ring Twine Cutters.
I, JAMES WALLACE of 859 Broadway, Oakland, County of Alameda State of
California United States of America, Gentleman, 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 :-
My invention relates to a convenient device for cutting twine.
It consists in the combination of a cutting blade with a ring which is adapted to
be worn upon the finger in such a manner that the blade will be in convenient
position to cut twine after a package has been made up.
Referring to the accompanying drawings for a more complete explanation of my
invention

Figure 2 is a sectional view shewing the manner of attaching the blade to the
ring.
A is a ring of such size as to fit the finger of the user.
made of sufficient width to clasp the finger firmly, and give a good grip on the
The body of the ring is
inside to prevent its tilting when the knife or cutter is used.
The top of the ring, which is adapted to lie upon the back of the finger, is
extended rearwardly as shewn at A', to form a support for the cutting blade. This
blade B is curved or arched as shewn, the front end being rounded or blunt so as
not to cut the finger where it approaches it.
The rear end is formed with a tongue C which is adapted to fit a corresponding
hole in the extension A', and a similar projection C at the rear of the inner
cutting edge of the blade.
D is an opening made in the ring centrally beneath the cutting edge of the blade
for the purpose of sharpening.
The inner concaved edge of the blade is made sufficiently sharp to cut any
twine which may be drawn across it. This edge arches upward from the point or
lug C which is at the rear of the cutting edge, extending upward over the
opening D and then extending down beyond the front edge of the ring, the point
being situated a little below the level of the top of the ring or approximately
midway between the outer aud inner periphery of its thickness. Constructed in
his manner, the ring is placed upon the index finger with the cutting blade.
bending forward.
The rearward extension A' which serves as an attachment for the blade B, also.
erves as a support to hold the ring firmly and resist the pull upon the blade when
he twine is to be cut.
The curvature and position of the blade are such that the twine introduced
beneath the point of the blade is drawn backwardly over the concaved edge and
vill be easily cut, either in the front portion or rear of the cutting edge.
The opening D made in the ring is of considerable size, and serves to admit a
harpening device by which the blade can be always kept in good condition.
This sharpening device may consist of an emery stick or other suitable material
which can be thus easily drawn across the edge of the blade to sharpen it whenever
t becomes dull.

page_text: 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 :-
A twine cutting device consisting of a ring adapted to fit the finger having a
rearward extension upon the back and an opening made between said extension
and the front edge of the ring, a concavo-convex blade, the rear end of which is
fixed to said rearward extension, the front end projecting over and beyond the
front edge of the ring and having the inner concave sharpened edge in a plane
above the opening in the ring.
