专利汇可以提供Apparatus for making ceramic shingles from extruded hollow blocks of soft clay专利检索，专利查询，专利分析的服务。并且Ceramic shingles are produced from hollow blocks of soft clay cut from an extrusion. Each block is die formed at one end to produce an inward directed lip which will form the lower portion of a shingle. The blocks are stacked on parallel side edges while being heated to vitrify the clay, and afterwards portions of each block are discarded to produce two substantially duplicate ceramic shingles. Apparatus for die forming the hollow blocks of soft clay include internal and external dies to form the inward directed lips.，下面是Apparatus for making ceramic shingles from extruded hollow blocks of soft clay专利的具体信息内容。

权利要求

1. Apparatus for making ceramic shingles comprising, in combination: means for producing a hollow block of soft clay having parallel external top and bottom surfaces and parallel external side surfaces, internal die means, means for placing the internal die means within the hollow interior of said block through relative movement of said die means and said block, external die means movable with respect to said block and cooperating with said internal die means to deform and shape one end of the block to form a pair of inwardly directed lips each merging with one of said top and bottom surfaces, respectively, said formed block being shaped for stacking with duplicate blocks on their side surfaces to permit simultaneous firing of the stacked hollow blocks in a kiln.

2. The combination set forth in claim 1 in which a movable table is provided to support the hollow block, and stationary internal dies are received within the hollow interior of the block upon movement of the table.

3. The combination set forth in claim 2 in which external dies move in a direction at right angles to the movement of the table to cooperate with the stationary internal dies to form the inwardly directed lips.

4. Apparatus for making ceramic shingles comprising, in combination: means for producing a hollow block of soft clay having parallel external top and bottom surfaces and parallel external side surfaces, stationary internal die means, means for placing the internal die means within the hollow interior of said block, said means including a movable table for supporting the hollow block, external die means movable with respect to said block and cooperable with said internal die means to deform and shape one end of the block to form a pair of inwardly directed lips each merging with one of said top and bottom surfaces, respectively, said formed block being shaped for stacking with duplicate blocks on their side surfaces to permit simultaneous firing of the stacked hollow blocks in a kiln.

5. In a device for forming a pair of soft unfired clay shingles from an extruded hollow rectangular block of soft clay, the improvement comprising, in combination: a movable table to support the hollow block, stationary internal die means, means for moving the table and hollow block in one direction to place the internal die means within the interior of the hollow block, external die means, means for moving said external die means with respect to said block to cooperate with said internal die means to deform and shape the block to form a pair of inwardly directed lips at one end of the block, and means for moving the table in the other direction to separate the formed block from the internal die means.

6. The combination set forth in claim 5 in which said external die means comprises oppositely moving external dies engaging opposite faces of said hollow block.

7. The combination set forth in claim 5 including a separator tool, and means for moving the separator tool to engage said internal die means to cooperate with the internal and external die menas in forming siad lips.

8. The combination set forth in claim 5 including curved blade members, and means for moving said bladE members laterally into engagement with said hollow block after forming of the lips in order to define the side edges of the lips.
