This invention relates'to can openersand'more particularly to can opener cutter assemblies.

i This application is a continuation-in-part of Serial No. 129,139, fil'edj'No'vember 23 1949, 'now PatentNo1-'2 ,602,991-, andserial No. 204533, filed January 5,'1951,'now Eatent N0.-2,619,718.

An'object of this invention isto provide a can opener cutter assembly having a cutter which is easily removable by the housewife for cleaning,"sharpening and replacement. A further object of this inve'ntio'nis to provide a can opener witha cutter locking arrangement which will lockonly whenthe cutter isproperly positioned onits support "'Otherand furtherobjects of this -invention will appear irom'the following description.

The invention as hereinafterdescribedjcomprises a can opener cutter assembly which is mounted upon a can opener I operated by a handle H. Mounted on'the same shaft I2; as the handle is a feed wheel [3. By operation of the handle H the can opener cutter-assembly is moved toward and away from the feed wheel 13 in the can cutting operation. On an inset portion [4 ofthe housing of the opener is a screw l5 to which may be attached an L-shaped bracket 16 supporting a can top removing magnet H. The L-shaped bracket l6 has one arm 16a bifurcated to engage screw [5 and one arm 16b apertured to receive a screw attachment l8 on the magnet l1. Arm [6a is adjustable on screw [5 to position the magnet at a greater or lesser distance from the opener.

Above the feed wheel l3 there is a recessed opening IS in the housing wherein is located the cutter assembly. This assembly has a base 20 formed on aeplateoflthe inner mechanism-oithe opener on which is mounted an inclined-cutter post 2|. .This postfis 'enlarged at; its 'base to form a shoulder Zla wagainst which-the-cutter 22 abuts The outer extremity ofithe' post is of reduced diameter. and has-nearbits end a circumferential '-groove -2Ibiwhich receives the hooked end of locking clip orfifingerz23e The cutter member 22 consists of a bearing disk 22a, a'blade 2212, a central post-holeand an annular hub 22c around the post-hole on theouterablade side. Parallel to and spaced rearwardlyfof the cutter post is an inclined post 24 which-,asmore fully expl'aine'd 'in .my. .copendin'g application Serial No. 204,533gis engagedib'y the upper rim of the can during the lid-severing operationand exerts an obliquely 'directeddownward-force thereon to prevent the cani from tilting, tD Stabi-r lize it in upright position and to iotherwise'assist in the cutting operation.= V At the end of-post 24 ispivotallyattached-a hooked-shaped lockingclip 23'having a recess 23a on itsunder edge adapted-to engage the groove 2|b in the cutter post. A projectionor tit 23b is positioned between the recess-23a and the pivot point on the edge of the'locking clip to abut the cutter bearing disk 22a when the cutter has been reversed. and is improperly mounted on the cutter post. Thetop of the clip is bent to form a flange 230 which facilitates operationof' the clip.' In Figs. 3,4, and 5, the cutter is shown with the'locking clip engaging the cutter post securing thecutter in its proper "*To remove the cutter 22 from its post 2 I the clip'23 is disengaged 'fromthe cutter postgroove 2 l and swung up' to the position shown i'n dottedlines in Fig. 4; If the cutter andieed wheel'liha've beenseparated by rotation of the handle"! l, as shown inFi'gsJ3; 4,an'd 5; the cutter may then'i'be "slid off its post for'suchpurposes as cleaning-sharpening orrepla'cin'g. 3rd replacethe'cutter it' is slipped back on its post=','-*but in order 'to' 'do' some bearing disk 1 2211 must be inside and the blade 22!) outside. If the cutter is reversed the clip 23 cannot be lowered since the projection 231) will contact the edge of the bearing disk 22a and prevent the clip from being moved into locking engagement with the cutter post. This results from the annular hub 22c abutting shoulder 2la of the cutter post. The annular hub 210 on the blade side of the cutter thus eifectively prevents improperly positioning the cutter on the post. When the cutter is properly placed on the post, with the
