Abstract

A food-cutting apparatus comprises: a longitudinal supporting frame mounted in upright position on a base; an upper frame and a cutting plate below the upper frame both of which are fixed to a front surface of the supporting frame in lateral position; a longitudinal rotary main shaft provided on the upper frame movably up and down and provided with a holding member for a work at its lower end; a worm wheel meshing with a worm formed on the main shaft; a brake ring and a handle for moving the main shaft up and down, both of which are provided on a rotary shaft of the worm wheel; a brake shoe abutting on the brake ring for controlling a rotation of the worm wheel; a cover for enclosing a cutting operation area above the cutting plate, which cover is openable horizontally; an electric motor rotatably driving the main shaft; and a main switch provided in a control circuit for the motor; which food-cutting apparatus is characterized by further comprising: a stop means having its front end engaging portion engage with the worm wheel, which stop means is so supported that the front end engaging portion is travelable between a first position where the engagement with the worm wheel is established and a second position where the engagement is resolved; and a supporting member for the stop means, which is disposed on the upper frame.

Claims

1. A food-cutting apparatus comprising:

a longitudinal supporting frame mounted in upright position on a base;

an upper frame and a cutting plate below said upper frame both of which are fixed to a front surface of said supporting frame in lateral position;

a longitudinal rotary main shaft provided on said upper frame movably up and down and provided with a holding member for a work at its lower end;

a worm wheel meshing with a worm formed on said main shaft;

a brake ring and a handle for moving said main shaft up and down, both of which are provided on a rotary shaft or said worm wheel;

a brake shoe abutting on said brake ring for controlling a rotation of said worm wheel;

a cover for enclosing a cutting operation area above said cutting plate, said cover being openable horizontally;

an electric motor rotatably driving said main shaft; and

a main switch provided in a control circuit for said electric motor;

characterized by further comprising;

a stop means having its front end engaging portion engage with said worm wheel, said stop means being so supported that said front end engaging portion is travelable between a first position where said engagement with said worm wheel is established and a second position where said engagement is resolved; and

a supporting member for said stop means, said supporting member being disposed on said upper frame.

2. The food-cutting apparatus as set forth in claim 1, wherein:

said stop means is provided with a rod which is both rotatable and slidable in a through-hole provided in said supporting member, at a front end on which rod is formed said front end engaging portion having an inclined end surface engaging with said worm wheel, behind which engaging portion is formed a flange, around which rod a coil spring is mounted between said flange and said supporting member for biasing said rod toward said worm wheel, said rod being brought into said first position or said second position where said inclined end surface is directed up or down through a rotation of said rod, behind said rod is provided a stop pin which engages with a rear surface of said supporting member in said first position or said second position.

3. The food-cutting apparatus as set forth in claim 1, wherein:

said stop means is provided with a rod which is both rotatable and slidable in a through-hole provided in said supporting member, at a front end of which is formed said front end engaging portion engaging with said worm wheel, behind which engaging portion is formed a flange, around which rod a coil spring is mounted between said flange and said supporting member for biasing said rod toward said worm wheel, further which rod is provided with a pin in a rear portion thereof, which supporting member has an opening in a rear side thereof and is provided with a sleeve in which a long slit is formed in which which slit said pin is inserted.

4. The food-cutting apparatus as set forth in claim 1, wherein:

at a lower end of said upper frame is provided a sub-switch on-off operation of which is performed by opening-and-closing operation of said cover, which sub-switch is connected with said main switch in series in said control circuit for said electric motor.

5. The food-cutting apparatus as set forth in claim 1, wherein:

said holding member is formed by a base plate, a plurality of holding pins and a cover, which base plate is provided with a plurality of through-holes in which said plurality of holding pins are inserted.
