Core trimmer

An improved core trimmer for removing extraneous material having predetermined dimensions from prefabricated or manufactured products, comprising in combination with a driving means for rotatably driving said trimmer:

• a housing, said housing having a first and second end portion, a cutting means, a transmitting means having a transmitting shaft and for rotatably transmitting torque to said cutting means, a means for providing leverage to said cutting means such that the cutting means engages a surface portion of a work-piece for cutting, said housing further including a centrally disposed drive bushing and a cutter advance block;
• a means for ejecting at least one severed work-piece material of said predetermined dimensions, and
• a means attached to said transmitting means for setting and adapting an electro-motor means thereto;
• wherein the transmitting shaft further comprises a tapered lever arm mounted in adjacent and abutting relation with a face portion of the cutter advance block of predetermined slope for selectively rotating the drive bushing.
