1 Claim. (Cl. 220--52)
24 has semi-circular side sections de?ning a central hole
25, within which the protruding end of the tear strip TS
is adapted to engage and be wound up into spiral condi
tion 26 leaving a groove 27 in the outer portion of the
can C above the rib R thereof.
Operation
This invention relates to can openers, and more par
ticularly to a can opener adapted for severing the tear
strip from a coffee can, and winding it into spiral form
on the outside of the can.
A further object is to provide a device of the above
nature which will be simple in construction, inexpensive
to manufacture, easy to install and manipulate, compact,
ornamental in appearance, and very ef?cient and durable
in use.
With these and other objects in view there has been
illustrated on the accompanying drawing one ‘form in
which the invention may conveniently be embodied in
practice.
In the use of the present can opener, the split sleeve 23
with its center hole 25 will be ?tted over the end protrud
10 ing tongue of the tear strip TS, which normally extends
parallel to the can C. The arcuate plate 16 will then be
placed over the top edge of the can, with the short lug
11 and the long fulcrum ear 12 engaging the outside rim
of said can. The ‘lower inturned end 13 will then be lo
15 cated under the bottom of the tear strip TS.
Upon grasping the radial horizontal handle 16 in one
hand of the user, the knob 21 of the L-shaped rod 19
will be turned clockwise by the other hand of ‘the user,
to cause the tear strip TS to be severed from the can C
20 and wound into the spiral form 26 upon the sleeve 23

FIG. 1 represents a top plan view of the improved can
opener as it appears when in operating position assembled
upon the top edge of a coifee can.

(see FIG. 4).
It will be understood that while the tear strip TS is
being wound up into spiral form around the split sleeve
