The combination of a knife-bar having one of its ends provided on its upper face with an extension having a beveled underfaee, a series of vertically-arranged lugs carried by the said knife-bar, a series of removable eiltter-blades arranged on said cutter-bar, a locking-bar provided with a series of slots to reeeive the upper ends of the said lugs, and having one of its ends beveled and arranged under the said extension, and means whereby said knife-bar and locking-bar are locked together.

2. The combination with a knife-bar and a series of lugs arranged thereon, saidlugs having elongated upper ends provided with beveled under surfaces of a series of cutterblades arranged between the said lugs, a looking-bar provided with a series of openings to receive the upper ends of the said lugs, a locking-boltarranged between the said knifebar and looking-bar, said locking-bolt provided with an angular head seated in an opening in the knife-bar, and a nut on Vthe outer end of the said bolt.

3. The combination with a knife-bar havf under the said extension, a locking-bolt arranged between the said knife-bar and locking-bar and provided with an angular head seated in an opening in the knife-bar, a nut on the outer end of the said bolt, and means for preventing the rotation of the said nut, substantially as-deseribed.
