Abstract: To divide a unit of cheese, such as a wheel or block of cheese, into individual pieces of different sizes and shapes, the unit of cheese is placed on a support surface and is moved relative to a cutting device. The cutting device is made up of a network of knife-like blades each with a cutting edge and the blades are arranged to divide the unit of cheese into the desired shaped pieces. The entire unit of cheese is cut up into the individual pieces in a single cutting operation. In the cutting operation, the unit of cheese is placed on a support part movable relative to the cutting device. The support part is subdivided into surface parts each having a shape corresponding to the shape of one of the individual pieces of cheese. the support part is movably mounted on upwardly extending guide elements. The cutting device is held in a stationary position on the guide elements. The support part and the cutting device are replaceably mounted on the guide elements.

Abstract: A hacksaw machine comprises an upper and a lower horizontal bracket, a swinging arm in each one of the brackets and a driving mechanism for pivoting the lower swinging arm. A saw-blade connects the front ends of the swinging arms. The lower swinging arm is twice as long as the upper arm. Both swinging arm are tensioned in opposite directions by springs respectively which are adjustably fastened at the brackets. The swinging mechanism is independent on the lengths of the brackets.

Abstract: Apparatus for cutting a block of foamed material to the size of a laminate adhered thereto includes a support table and a carrier frame pivotally attached to the table. The carrier frame carries an electrical resistance wire and maintains same constantly under tension. The frame is vertically swingable to pass the wire through the foamed material along a clearly delineated line with respect to which the block is precisely located. This line is in registry with a transverse groove in the table which divides its supporting surface into sections on either side thereof and at right angles to an upstanding guide member extending along one side edge of the table.

Abstract: A kitchen utensil for the preparation of food and adaptable and easily convertible to numerous uses such as chopping, juicing, dicing, slicing, comminuting, can opening and cracking of nuts. All food processed is collected in a receptacle forming a basic element of the apparatus. Novel means are disclosed for the quick but firm attachment of a chopping blade and can opener, to an operating lever, for use over the receptacle.

Abstract: An apparatus for making semi-circular pipe insulation segments from a block of foamed glass of like foamed, expanded or cellular plastics or elastomers having reciprocating adjustable cutter members mounted on a reciprocating frame structure, which cutter member travels in an arcuate path through the block placed below the cutter members, the improvement of which comprises a rigid adjustable blade assembly.

Abstract: A self-contained, multi-blade package is constructed to be mounted in the blade head assembly of a slurry saw for cutting hard materials such as quartz, silicon, germanium, and the like. The blade package is pre-assembled with connecting rods extending through aligned holes of spacer plates and end caps which extend above and below the blades at either end of the blades. At least one end cap of each pair is drilled with a through hole or holes and counter bored to receive a nut threaded on the connecting rod which projects into the counter bore. The end caps have a thickness on the order of one-half their width dimension resulting in great dimensional stability. This prevents distortion of the blade pack when the nuts are tightened on the connecting rods ensuring parallelism and rigidity of the blade package. The end caps further eliminate the need for clamping blocks normally used in the blade head assembly of slurry saws thereby permitting more blades to be incorporated in the blade package.

Abstract: To floatingly support a saw blade in a frame, the frame is formed, at its free ends, with forked elements; clamping elements are clamped to the saw. The engagement between the forked element (the blade fitting between the gap in the fork) and the clamping element is by means of a depression-projection fulcrum engagement, so that the clamping element, to which the saw blade is attached, can rock or tilt with respect to the forked element, attached to the frame, thus avoiding holding stresses on the saw blade which lead to breakage of the blade at the attachment or clamping points.
