Abstract: A metal panel shear cutter is designed for metal panels which include support ribs. The metal panel cutter utilizes an anvil type cutting blade positioned at each side of a cutting base. Each cutting blade is pivotally connected to a cutting base in the vertical plane. The cutting base also includes supports for the ribs of the panels to allow for a smooth and clean cut of the panel. The cutting blades and a small portion of the cutting base are pivotally connected to the cutting base in the horizontal plane so they may be pivoted to the desired cutting angle while the metal panel remains fixed with respect to the base. This pivotal portion of the base includes additional supports for the ribs of the panel. These supports are adjustable to accommodate the various angles at which the panels are to be cut.

Abstract: A slicing device includes a base for supporting a foodstuff to be sliced and a repositionable knife or blade having a pair of bosses disposed at one end of the blade that extends outwardly away from the blade. The pair of bosses of the blade is coupled to a blade holding rack that acts as a pivot or fulcrum for the blade. The pivot or lever action of the blade permits a user to easily cut through large or hard foodstuff. In one embodiment, the blade is adjustable in the rack to permit a user to lower the blade to make successively deeper slices into and eventually through the foodstuff.

Abstract: A shear type miter cutter has a pivotal blade and four linearly sliding blades. The linearly sliding blades may be manually linearly positioned to preset locations for a particular size or type of stock material. The linearly sliding blades are further linearly adjusted automatically upon rotation of a stock material support fence, to ensure optimum alignment between the pivotal blade and the linearly sliding blades. The automatic adjustment allows an operator to make rapid changes in cut angles for a given stock material, while still yielding finished cut edges of high quality and precise angular orientation. A variety of designs for rapidly manually setting the cutter to specific preset angles and specific stock materials are also disclosed.

Abstract: The invention relates to a scrap shearer comprising a displaceable frame (1) and a pair of blade units (2, 3) shearing in a scissor-like manner, whereby the blade units are fastened on the frame (1) so that at least one of the blade units (2, 3) is pivotable. The object of the invention is to provide a scrap shearer which is displaceable to such large scrap objects as e.g. ships and which is capable of advancing within the scrap object, by means of which shearer the requirements of different kinds of scrap objects can be taken into account in the best possible way. This is achieved according to the invention in such a manner that fastening means (7, 8, 11) of the pivotable blade unit (2) are adjustable for the adjustment of the shearing gap and/or angle between the blade units (2, 3).

Abstract: The cutting tool has a circular blade having a center hole and a plurality of pivot holes spaced apart on a common radius with a handle fixed to the center hole and one of said pivot holes. A pivot shaft extends between spaced side plates and the blade is mounted on said pivot shaft. Each side plate has a throat and an anvil welded to each side plate at the rear lower corner of the throat. Each anvil has a bed plate and a back plate on which and against which the material to be cut is positioned. A blade guard depends from the handle and is contoured to lie close to the adjacent circumference of the blade and extend across the throat when the handle is in its lowermost position.

Abstract: A knife assembly for shearing angle stock has a square, plate-like, floating cutter provided with a pair of opposed, flat, parallel faces, presenting four, stock-engaging corners each having two pairs of cutting edges, permitting eight "settings" used successively as wear, breakage or dulling may require. Four rigid stops and a pair of floating abutments are provided so that during use, regardless of which of two directions the knife tends to rotate when engaging the stock, it is firmly backed up within a cutter-receiving recess formed in a shiftable cutter support.

Abstract: A cutter for ribbed sheet metal building panels wherein anvil blocks are mounted on the base table adjacent the shear edge of the base table which normally cooperates with the cutting edge of the swinging shear blade. The anvil blocks define sharp cornered oblique cutting edges shaped according to the shape of the ribs of the sheet metal panel; and the anvil blocks have obliquely oriented fore and aft sides to prevent interfering with the ribs when the sheet metal panels are obliquely oriented with respect to the shearing edge of the base table.

Abstract: A shear for cutting bar stock includes upper and lower cutting blade supports each having a cutting blade, and a hold-down member, all pivotally connected about a working bearing. This assembly is pivotally mounted about a second bearing or pivot axis on one end of a frame of the shear, and is height-adjustable by a lockable hydraulic actuator attached to the upper cutting blade support at the opposite end of the shear, to provide vertical adjustability of the cutting point with minimal horizontal or angular displacement thereof. Preferably, the two pivot axes and the cutting point are coplanar. The upper cutting blade support is pivoted relative to the lower one by a hydraulic actuator engaging the upper support at one upper part thereof which is not so coplanar, to provide both a relatively long lever arm and a relatively long cutting arm for minimizing arcuation of the cutting movement. One cutting blade is adjustable within its support for optimum positioning taking into account the shape of the stock.

Abstract: A knife cutter for the angular profiles includes a plate, generally triangular in shape, the posterior surface of which has a prismatic projection corresponding to one of the sides thereof. The side and the prismatic projection are arched in order to adjust in a complementary recess made for such purpose in the front surface of the knife bearing plate. The other two sides of the knife or the cutting edges thereof form a dihedral and are parallel to the cutting edges of a counter-knife.

Abstract: The machine comprises an operating arm accommodated with a pair of horizontally extending shoulders and is rockingly supported by a pin pivoted on parallel vertical supporting standards or uprights for said shoulders and forming part of the machine bedplate. The pin may be vertically moved along slots formed on said standards or uprights. The working plane is horizontal and may be rotated about a vertical axis and with said shoulders forms a cavity. Said plane has attached thereon the several counter-tools for the punching, nibbling and cutting operations and peripherally has cut profiles for rounding off. A mechanism is carried by the horizontal shoulders to cause the rocking movement for said operating arm and relative associated toolholders.
