  • An electrically powered can opener according to the ter base'being unified by said pivotal shaft, and a latching member operable from the exterior of the housing for the purpose of precluding withdrawal of said base.
  • a feed wheel holder carrying a rotary cutter fixedly is supported on said base for-fee rotation and is con'- nected for axial separation to the end extremity of a driving shaft extenting beyond the upright front'member of the housing from the-interior of same.
  • the pivotal shaft is supported bythe upright front member and is latched by the latching membernot to be withdrawn, the feed wheel holder is in position to be connected to and rotated by thedriving shaft;
  • the pivotal shaft is made separable by operating the latching member, the cutter base. carrying the rotary cutter and the base carrying the feed wheel holder can be withrawn as a unified body from the housing for the purpose of washing.
  • cleaningwork becomes very easy and the contamination of the cutter or the toothed feed wheel with lubricating oil of the driving shaft is eliminated.
  • FIG. 1 is a front elevational view of an electrically powered can opener
  • a cutter base 15 having an integral grip 15' at one end extremity and a pivotal hole 15" at the.
  • pivotal shaft 16 inserted in the pivotal hole 15 and the bearing boss 13 and to the end portion of the pivotal shaft a nut 17 is in threaded connection with pivotal shaft 16 for unification of the pivotal shaft and the cutter base and for precluding withdrawal of the former.
  • the intermediate portion of the pivotalshaft 16 is provided with a head 18 and between this head and the nut 17, another nut 19 is in connection with pivotal shaft 16 as a spacer.
  • a cut- .tercarrying stud 20 is extending in an oblique downward direction and, a rotary circular cutter 21 is mounted rotatably on the stud 20, withdrawal of the cutter being prevented by a screw 22 afiixed to the end extremity of the stud 20.
  • a magnet 23 is held forwardly of the cutter 21 by an arm 24 extending from the upper portionof the cutter base 15.
  • a base 25, which has such a size that it can be positioned on the front surface of the depressed portion ll, is provided with a pair'of perpendicular stopping members 26 at both sides of the base.
  • stopping members are made thin as shown and the lower edges of the same have cuts 26' and 26' respectively.
  • a loose aperture 27 is bored and the part of the pivotal shaft 16 between head 18 and nut 19 is inserted rotatably within this loose aperture 27.
  • the stopping members 26 are inserted in the interior of the housing through slots 25' formed through the depressed portion ll of the upright front member 10'.
  • a push out spring 28 is secured on the front surface of the depressed portion 11 whereby the base 25 placed closely before the front surface of the depressed portion 11 is biased forwardly of the housing by the push out spring 28.
  • the lower portion of the end rim of a can to be opened is made in contact with the toothed feed wheel 30 and the grip of the cutter base 15 is gasped to be lowered, the start push button 53 is depressed by the grip 15' to close the electrical contacts 55 and 55' and the electric motor 42 is started to rotate the driving shaft 36 through the reduction gear assembly 43.
  • the toothed feed wheel is rotated with support by the driving shaft 36 immediately when the projection 38 is fit in the jointing groove 32 and after only the driving shaft 36 rotates to fit the projection 38 in the jointing groove 32 due to the biasing force of the planar spring when the projection 38 is not fit in the jointing groove 32.
  • the rotary cutter 21 proceeds to open the can.
  • the above-mentioned torque disappear and the grip 15 is lifted slightly by a restoring spring suitably provided. Then the electrical contacts 55 and 55 are disconnected to stop the electric motor 42. The opened can can be withdrawn from the can opener by further lifting the grip 15.
  • the engaging relationship between the latching member 45 and the stopping members 26 is released by depressing the push button 52 to lower the latching member'45 once and then making the cuts 26' out of registrationwith the lower edge of the opening 51. Because no members prevent the cutter base 15 and'the base unified by the pivotal shaft 16 from moving forwardly of the housing 10, the base 25 and the cutter base 15 are pushed forth slightly by the force of the-push out spring 28 the planar spring 41 in the absence of the push out spring 28) urging the base forwardly and keep their slightly pushed out position. Then, the cutter base 15 carrying the rotary cutter and the base 25 carrying the toothed feed wheel are withdrawn from the housing 10, the situation shown in FIG. 7 being attained.
  • thevtoothed feed wheel 30 is separated from the housing 10 very readily and quickly by releasing the engagement between the stopping members 26 and the latching member 45 and cleaning work of the toothed feed wheel becomes very easy.
  • contamination of the toothed feed wheel 30 with lubricating oil of the driving shaft 36 escaping in washing solution at the time of washing is avoided, because the toothed feed wheel 30 is separated from the driving shaft therefor and the periphery of the aperture 29 can practically dispense with the provisionof lubricating oil.
  • provision of lubricating oil for the driving shaft 36 is not necessary as the lubricating oil on the driving shaft 36 is not washed off.
  • an electrically powered can opener having a housing, a driving shaft rotatably supported in said housing and an electric motor for rotating said driving shaft, a combination therewith of an upright front member of said housing, a cutter base having a grip at one end portion, a rotary cutter rotatably carried by said cutter base, a base closely mounted on said upright front member and provided with two loose apertures, a pivotal shaft affixed to said cutter base, said pivotal shaft extending through one of said loose apertures, said base being disposed on said upright front member, means unifying said cutter base and said base in cooperation with said pivotal shaft, 2.
  • An electrically powered can opener as described in claim 1 including a spring secured on said upright front member, said spring biasing said base away from said upright front member.
  • Att0rneyl(emon, Palmer & Estabrook [57] ABSTRACT A cutter suitable for cutting, for example, swaged-on metal collars of lockbolts to facilitate removal of the lockbolts has two blades movable to bring their cutting edges together to cut a collar beteen them, and has resilient guides attached to the blades for guiding the blades to cut a collar or other workpiece symmetrically.
