Quick-change cutting blade assembly and method
11577420 · 2023-02-14 · ·

A quick-change cutting assembly includes a base having a support surface for supporting a cutting blade, a clamping arm having a clamping surface, a spring interposed between the base and the clamping arm, and a pivot defining a pivot axis between the spring and the clamping surface that couples the clamping arm to the base. The spring biases the clamping surface toward the support surface and a cutting blade therebetween. The clamping arm is pivotable between a closed position where the clamping surface is parallel to the support surface and an open position removed from the closed position where the clamping surface is spaced further from the support surface. The cutting assembly further includes a locking pin transverse the direction of biasing action of the spring that connects the clamping arm to the base to prevent the clamping arm from pivoting relative to the base when in the closed position.

20230011013 · 2023-01-12 ·

A blade removal device removes a blade of a slicer. The removal device has: a base positioned with a contact side on one side of the blade; fasteners supported in the base, rotatable from an attachment position for attaching the blade removal device to the blade into a holding position for holding the blade; and a rotary handle supported on the base and rotatable relative to the base from a closed position into an open position to release an interlock between the blade and the drive. The interlock opens when the rotary handle is in the open position and is closed when the rotary handle is in the closed position. The fasteners in the attachment position engage in cutouts of the rotary handle in the closed position. The cutouts and the fasteners are out of engagement when the rotary handle is in the open position.
