PROVISIONAL SPECIFICATION.
Improvements in Implements for Cutting Twine and the like.
We, JACOB CRANDALL and OSCAR WILLIAM SHERWOOD, both of Westport,
Mendocino County, California, U.S.A., Inventors, do hereby declare the nature
of this invention to be as follows:-
This invention relates to improvements in implements for cutting twine, string,
thread or thin wire.
An implement of the kind above mentioned, and constructed in accordance
with our invention, will be found especially useful to shop assistants and others
who are constantly tying up parcels, dress makers and tailors for cutting thread,
and florists for cutting of wire for binding together flowers.
The invention comprises a narrow band of metal, bent in such manner as to
fit around the finger; but its ends do not meet and are bent upwards and then
inwards to form opposite cutting blades. The band is prevented from turning
upon the finger by hollow surfaces formed on opposite sides thereof and adapted
to fit the sides of adjacent fingers. If desired, however, partly circular lugs may
be formed on the band to fit beneath the adjacent fingers.
Thread, twine or the like to be severed is placed between the blades, and the
band, being squeezed between the fingers, causes the blades to sever the twine
between them.
In an alternative form, the band is substituted for a complete ring having a
lug upon its upper part in which a fixed cutter, having V-shaped cutting edges,
is secured. In this form, twine to be cut is passed around the lug and is severed
by the projecting cutter when slightly jerked.

COMPLETE SPECIFICATION.
Improvements in Implements for Cutting Twine and the like.
We, JACOB CRANDALL and OSCAR WILLIAM SHERWOOD, both of Westport,
Mendocino County, California, U.S.A., Inventors, do hereby declare the nature
of this invention, and in what manner the same is to be performed to be par-
ticularly described and ascertained in and by the following statement:-
-
Our invention relates to a twine cutting attachment for finger rings; and it
consists essentially, in a peculiar construction of the ring with bracing arms and
a means for removably seating the cutting blade therein and exposing the edges
and guides by which the twine is brought into contact therewith.

page_text: Referring to the accompanying drawing, the figure is a view of the ring.
In the application of cutters of any description to a ring or device by which it
may be conveniently held upon the finger of the operator it has been difficult to
prevent the ring from. turning when pressure is brought upon it; and our
invention is designed, primarily, to hold the ring in its proper position, pre-
venting its turning, and providing a proper resistance when the twine is being
cut.
A is a ring of suitable size to fit the finger of the user, and this ring has a
head B projecting outwardly from it. This head is made integral with the body
of the ring and has lugs or arms b, b projecting from the upper part, following
the line of peripheral curvature of the ring, and at such a distance therefrom as
to leave open channels between these ends 6 and the body of the ring. This head
is made of approximately the same thickness as the ring, and it has a V-shaped
slot made through it, the length being sufficient to receive a knife or cutter C.
This knife or cutter is of tapering or wedge shaped form, being the widest at the
top, tapering downward, so that it will fit snugly into the slot or channel and so
that its sharpened edges are presented across the openings formed between the
body of the ring and the projections b, so that a thread or twine drawn into
either of the openings will be brought into contact with the edge of the cutter,
and thus severed. This cutter is seated in a correspondingly shaped channel, as
before described, and is secured in place by a small screw c passing transversely
through it and removable at any time for the purpose of removing and sharpening
the cutters.
In order to prevent the ring being turned by the pressure brought upon one
side of it when the twine is introduced to be cut, I have shewn projecting curved
arms Dextending in either direction from the body of the ring, with which they
are made integral, and upon the opposite sides of the cutter. These arms are
curved to fit within the fingers adjacent to the one upon which the ring is worn,
whilst the cutter is on the exterior or outside of the fingers. The curvature of
the arms is approximately the same as that of the ring itself, and these arms
act as braces, pressing against the adjacent fingers to prevent the ring being
turned when the twine is being cut.
The contrivance is exceedingly effective and convenient for the purpose required.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
(1) A thread or twine cutter consisting of a ring having a head projecting upon
one side with arms projecting therefrom in the line of curvature of the ring,
forming channels between themselves and the ring upon each side, a tapering or
V-shaped knife having cutting edges on each side adapted to fit a correspondingly
shaped channel made in the head of the ring whereby the cutting edges cross
the openings upon each side of the head, a removable screw by which the cutter
is held in place and means for preventing the cutter from turning upon the
finger consisting of the curved lugs formed integral with the ring and pro-
jecting upon each side substantially as described.
(2) A ring fitted to the finger of the user having an exterior cutting knife, and
curved arms extending upon each side of the opposite portions of the ring and
adapted to engage the inner part of the fingers adjacent to the one upon which
the ring is worn.
