专利汇可以提供Machine for cutting slabs from ice blocks专利检索，专利查询，专利分析的服务。并且A rotatable table carries a plurality of open-bottomed holders for blocks of material to be cut, more specifically dry ice. Under the table is a sector plate of about 240* to 270* of arc and spaced from the bottom surface of the table by a vertical distance not greater than the smallest thickness of slab to be cut. Beyond one edge of the sector plate, is mounted an indexing platform the height of which can be adjusted according to the exact thickness of slab desired. Beyond the edge of the indexing plate and still within the open portion of the sector plate, is a horizontal bandsaw blade operable with a slight clearance space from the bottom of the table. The block to be cut slides upon the sector plate as the table rotates and drops onto the indexing platform. Means then are actuated to hold the block in suspension within the holder as the block approaches the saw blade. An even cut is made parallel to the bottom face of the block without danger of jamming or breaking the block. When the clamped upper portion of the block is carried over the sector plate again, the clamping means is released and the block falls to the sector plate in preparation for another cut. A chute is provided below the saw blade and a sweeper arm is actuated after every cut to remove any debris from the indexing platform.，下面是Machine for cutting slabs from ice blocks专利的具体信息内容。

权利要求

1. A cutting apparatus for cutting portions of predetermined thickness from blocks of material having polygonal cross sections comprising, in combination, a rotatable table, means to rotate said table, a plurality of block holder means on said table adapted to accept blocks of material to be cut, each of said block holder means having at least one substantially planar surface and a material-locking means for engaging the block of material to be cut and for rigidly pressing it against the said surface in the holder means, bandsaw means having an endless blade with a straight course positioned adjacent said table, blade holder means mounted on said cutting apparatus and positioned to resist deflection of said endless blade during a cutting operation, indexing means to advance the material to be cut from the holder means a predetermined amount so that it may be cut by the straight course of the bandsaw means and to actuate the material-locking means so that the material is firmly held in the block holder means against the said surface as it is cut by the bandsaw means, the portion of the block cut being essentially unsupported so that it is free to drop away from the bandsaw means at the end of the cut each block holder means having its said at least one planar surface positioned to pass over the straight course and oriented on said table so that a corner of a block of material initially contacts the straight course thereby facilitating the starting cut and so that the trailing edge of the block is substantially parallel to the straight course of the bandsaw blade as the trailing edge passes over said blade.

2. The apparatus defined in claim 1, in which the material-locking means comprises at least one plunger which is adapted to contact the block of material to be cut.

3. The apparatus defined in claim 1, in which the indexing means comprises a platform adjustable as to height located adjacent to and at a level below said saw means to receive and support material to be cut as it is advanced from the holder means so that the depth of cut may be determined by the height of the platform, and so that the material-locking means may be actuated to secure the material to be cut before said material contacts the saw means.

4. The apparatus defined in claim 3, together with a sector plate located below said table and parallel thereto at a height above said platform to support an initial advance of the material to be cut before said material is advanced to cutting position by being lowered to said platform.

5. The apparatus defined in claim 1 in which the material to be cut is solid carbon dioxide blocks having a rectangular cross section.
