Abstract: An electrically driven desk-top shredder which comprises a housing, a drive motor secured within said housing, and a shredding mechanism driven by said drive motor. The shredding mechanism comprises a pair of rotary shafts driven in mutually opposite directions by said motor, a plurality of rotary disks mounted on said rotary shafts and having a plurality of shredding blade about the outer periphery thereof, and a plurality of spacer members each having at least one cutting edge that engages with the shredding plate of a respective rotary disk in a gap formed between a pair of adjacent rotary disks.

Abstract: An adapter ring construction and cooperative arrangement with respect to an arbor for installing tooling on arbors or shafts such as the rotary disc shear knives which are mounted on arbors of slitters for strip metal slitting lines which are operated to continuously slit multiple strands from a wider continuously moving strip such as strip steel. The adapter comprises a ring-like member which is threaded onto a reduced threaded arbor stub shaft of each slitter arbor, after removal of clamping nuts from the stub shafts and retraction of the outboard bearing housing for a pair of cooperating parallel rotary shear knife mounting arbors. The ring-like adapter has a special outer annular contour in cross section which facilitates easy, rapid and damage-free telescoping of rotary shear knives and spacers onto the arbor for a changeover of desired spacing of the rotary knives when the desired strand widths of multiple strands to be slit are changed.

Abstract: A clamping collar is provided to be mounted about a shaft, arbor or the like, which may be secured at any position along the longitudinal axis of the shaft and preferably adjacent to the load on the shaft. The device comprises a pair of interfaced rings concentric about the shaft and arcuately shiftable one with respect to the other to shift locking lugs radially into and out of clamping engagement with the shaft. The device also includes means to make lateral pressure contact with arbor spacing sleeves, washers, spacers or flanges assembled on the shaft to space tool means, or the like, therebetween.

Abstract: Quickly adjustable, magnetically detachable spacing means for rotary slitting or shearing knives which permit the knives and spacing means to be loosened axially by the arbor nut and remain near their working positions on their supporting arbor while the axial spacing of any pair or pairs of knives is being changed. The spacing means may comprise one or more spacers of magnetic material and of conventional annular form and axial length having close sliding fit on the arbor. The spacer nearest a knife may carry permanent magnets with their poles near the axial face of the spacer proximate the knife to which semi-annular magnetic shims have been magnetically and detachably secured on diametrically opposite sides of the arbor. Substitution of a selected thicker or thinner pair of similar shims will increase or decrease the spacing of the knives as may be desired as by sliding the shims radially on the axial face of the spacer and over the poles of the magnets.

Abstract: A high bulk traveling web paper slitter for slitting a traveling web of a single layer or multiple layers with an unwinder for supplying the web and web processing equipment such as winders, sheeters, printing presses, etc., which take up the web and a slitting station having upper and lower rotating sharp edged slitting blades for slitting moving webs, and both the upper and/or lower sections can incorporate web support means with either or both driven independently or by the web and having drum surfaces on each side with the means suppporting the web reducing the dust, and the blades and support means being axially adjustable in position.

Abstract: A row of spacer blocks double as spacing means and scoring wheel holders so that a plurality of parallel score lines may be placed on a sheet of glass with a high degree of precision in the spacing of the score lines.

Abstract: The blade arrangement for meat cutters is such that the blades are mounted on a shaft in a form-locking manner and extensive continuous adjustment of the blades is possible while the blades remain firmly supported. With this arrangement the structure which secures the blades can bear extremely large forces at high shaft revolutions. The arrangement includes a driven shaft on which form-locking disks are mounted and between which a blade group is disposed. The blades of the blade group include a flange head which are guided in a radial direction on fixed guide surfaces on at least one of the disks. The flange heads of each blade of at least one blade group have one or more outer edges and one or more straight edge regions forming an opening. A guide bar is provided for the outer edges and a pin is provided for each opening.
